They are a set of human skills acquired via teaching or direct experience that are used to handle problems and questions commonly encountered in daily human life. The subject varies greatly depending on societal norms and community expectations
Ultraviolet traps called bug zappers are used to eliminate various small flying insects. They are attracted to the UV light, and are killed using an electric shock, or trapped once they come into contact with the device. Different designs of ultraviolet light traps are also used by entomologists for collecting nocturnal insects during faunistic survey studies
Atlantean alphabet are used to write Atlantean in the media of Atlantis: The Lost Empire. The letters c, f, j, q, v, x, z, ch, or th have likewise been acknowledged by the filmmakers as not being used. They were created so that Atlantean might be used as a simple cipher code. They are all also based on diverse ancient characters, just like the rest of the alphabet
Double Data Rate DDR memory controllers are used to drive DDR SDRAM, where data is transferred on the rising and falling access of the memory clock of the system. DDR memory controllers are significantly more complicated than Single Data Rate controllers, but allow for twice the data to be transferred without increasing the clock rate or increasing the bus width to the memory cell
The SDDS reader is mounted on top of a 35mm projector. The film is threaded through the reader before it passes through the picture aperture. As the film runs, red LEDs are used to illuminate the SDDS soundtrack. CCDs read the SDDS data and convert the stream of dots on the film into digital information. This information is pre-processed in the reader and passed on to the SDDS decoder
Mosaic is the art of creating images with an assemblage of small pieces of colored glass, stone, or other materials. It may be a technique of decorative art, an aspect of interior decoration, or of cultural and spiritual significance as in a cathedral. Small pieces, mostly roughly square, of stone or glass of different colors, known as tesserae,, are used to create a pattern or picture
Haptic technology has made it possible to investigate how the human sense of touch works by allowing the creation of carefully controlled haptic virtual objects. These objects are used to systematically probe human haptic capabilities, which would otherwise be difficult to achieve. These research tools contribute to the understanding of how touch and its underlying brain functions work
Besides earning a reputation as a respected entertainment device, the iPod has also been accepted as a business device. Government departments, major institutions and international organisations have turned to the iPod line as a delivery mechanism for business communication and training, such as the Royal and Western Infirmaries in Glasgow, Scotland, where iPods are used to train new staff
An extension on the brush building idea is the wattle and daub process in which clay soils or dung, usually cow, are used to fill in and cover a woven brush structure. This gives the structure more thermal mass and strength. Wattle and daub is one of the oldest building techniques. Many older timber frame buildings incorporate wattle and daub as non load bearing walls between the timber frames
High reach demolition excavators are more often used for tall buildings where explosive demolition is not appropriate or possible. Excavators with shear attachments are typically used to dismantle steel structural elements. Hydraulic hammers are often used for concrete structures and concrete processing attachments are used to crush concrete to a manageable size, and to remove reinforcing steel
The four difficulty groups – "Fun", "Tricky", "Taxing" and "Mayhem" – are used to organize the levels to reflect their overall difficulty. This rating reflects several factors, including the number of obstacles the player has to surpass, the limitation on the number of types of skills available to assign, the minimum rate of lemming release, and the percentage of lemmings that must be saved
A two-stage design has the benefit of minimizing ozone production, which would adversely affect health of personnel working in enclosed spaces. For shipboard engine rooms where gearboxes generate an oil mist, two-stage ESP's are used to clean the air, improving the operating environment and preventing buildup of flammable oil fog accumulations. Collected oil is returned to the gear lubricating system
Most of the above are used to avoid ambiguity when writing words of more than one syllable in pinyin. For example uenian is written as wenyan because it is not clear which syllables make up uenian; uen-ian, uen-i-an and u-en-i-an are all possible combinations whereas wenyan is unambiguous because we, nya, etc. do not exist in pinyin. See the pinyin table article for a summary of possible pinyin syllables
Numerous small explosives, strategically placed within the structure, are used to catalyze the collapse. Nitroglycerin, dynamite, or other explosives are used to shatter reinforced concrete supports. Linear shaped charges are used to sever steel supports. These explosives are progressively detonated on supports throughout the structure. Then, explosives on the lower floors initiate the controlled collapse
Digital editors are used to crop images. Cropping creates a new image by selecting a desired rectangular portion from the image being cropped. The unwanted part of the image is discarded. Image cropping does not reduce the resolution of the area cropped. Best results are obtained when the original image has a high resolution. A primary reason for cropping is to improve the image composition in the new image
Sinus infections are treated by prolonged courses of antibiotics. The development of nasal polyps or other chronic changes within the nasal passages may severely limit airflow through the nose, and over time reduce the patient's sense of smell. Sinus surgery is often used to alleviate nasal obstruction and to limit further infections. Nasal steroids such as fluticasone are used to decrease nasal inflammation
Aerial picture pairs, when viewed through a stereo viewer, offer a pronounced stereo effect of landscape and buildings. High buildings appear to ' keel over ' in the direction away from the centre of the photograph. Measurements of this parallax are used to deduce the height of the buildings, provided that flying height and baseline distances are known. This is a key component to the process of photogrammetry
Chest radiographs are used to diagnose many conditions involving the chest wall, bones of the thorax, and structures contained within the thoracic cavity including the lungs, heart, and great vessels. Pneumonia and congestive heart failure are very commonly diagnosed by chest radiograph. Chest radiographs are used to screen for job-related lung disease in industries such as mining where workers are exposed to dust
FireWire uses Data strobe encoding. In D / S encoding, two non-return-to-zero (NRZ) signals are used to transmit the data with high reliability. The NRZ signal sent is fed with the clock signal through an XOR gate, creating a strobe signal. This strobe is then put through another XOR gate along with the data signal to reconstruct the clock. This in turn acts as the bus's Phase-locked loop for synchronization purposes
Many natural treatments are used to treat the common cold. However, a 2007 review states that, "Complementary and alternative therapies are not recommended for treating common cold symptoms; however, ... Vitamin C prophylaxis may modestly reduce the duration and severity of the common cold in the general population and may reduce the incidence of the illness in persons exposed to physical and environmental stresses."
Computer graphics is widespread today. The Computer imagery is found on television, in newspapers, for example in weather reports, or for example in all kinds of medical investigation and surgical procedures. A well-constructed graph can present complex statistics in a form that is easier to understand and interpret. In the media "such graphs are used to illustrate papers, reports, thesis", and other presentation material
Prophecies of Earth changes have been described as a form of scientism, in which terminology and ideas borrowed from science are used to rationalize non-scriptural apocalyptical thought based on visionary experiences. David Spangler, a leader of the Findhorn Foundation spiritual community, described prophecies of Earth changes as an expression of collective fear and anger, rather than as foretelling of actual future events
Teepee or beehive burners are used to dispose of waste wood in logging yards and sawdust from sawmills by burning. As a result they produce a large quantity of smoke and ash, which is vented directly into the atmosphere without any sort of scrubbing or cleaning, contributing to poor air conditions wherever they are used. The burners are considered to be a major source of air pollution and are being phased out in most areas
In ongoing testing, Wolfgang Gruener, also writing in Conceivably Tech, said that cloud computing at cellular data speeds is unacceptable and that the lack of offline ability turns the Cr-48 "into a useless brick" when not connected. "It's difficult to use the Chromebook as an everyday device and give up what you are used to on a Mac / Windows PC, while you surely enjoy the dedicated cloud computing capabilities occasionally."
The use of air filters can trap some of the air pollutants. The Department of Energy's Energy Efficiency and Renewable Energy section wrote "[Air] Filtration should have a Minimum Efficiency Reporting Value of 13 as determined by ASHRAE 52.2-1999." Air filters are used to reduce the amount of dust that reaches the wet coils. Dust can serve as food to grow molds on the wet coils and ducts and can reduce the efficiency of the coils
Sales promotions are another way to advertise. Sales promotions are double purposed because they are used to gather information about what type of customers you draw in and where they are, and to jumpstart sales. Sales promotions include things like contests and games, sweepstakes, product giveaways, samples coupons, loyalty programs, and discounts. The ultimate goal of sales promotions is to stimulate potential customers to action
A helpful clinical test should predict a high risk for preterm birth during the early and middle part of the third trimester, when their impact is significant. Many women experience false labor and are falsely labeled to be in preterm labor. The study of preterm birth has been hampered by the difficulty in distinguishing between "true" preterm labor and false labor. These new tests are used to identify women at risk for preterm birth
Dogs today are used to find, chase, and retrieve game and, sometimes, to kill it. Hunting dogs allow humans to pursue and kill prey that would otherwise be very difficult or dangerous to hunt. Different breeds of dogs are used for different types of hunting. Waterfowl are commonly hunted using retrieving dogs such as the Labrador Retriever, the Golden Retriever, the Chesapeake Bay Retriever, the Brittany Spaniel, and other similar breeds
Designing the visual composition and temporal behavior of GUI is an important part of software application programming in the area of human-computer interaction. Its goal is to enhance the efficiency and ease of use for the underlying logical design of a stored program, a design discipline known as usability. Methods of user-centered design are used to ensure that the visual language introduced in the design is well tailored to the tasks
Since the NMPFT release, various names are used to designate the untitled films, such as "Leeds Bridge" or "Roundhay Garden Scene". Actually, all current online versions are derived from the NMPFT files, and these tentative titles are not canon to Le Prince whose mother tongue was French. However, "Leeds Bridge" is believed to be the original title, as the traffic sequence was referred as such by Frederick Mason, one of Le Prince's mechanics
Rods and cones differ in function. Rods are found primarily in the periphery of the retina and are used to see at low levels of light. Cones are found primarily in the center of the retina. There are three types of cones that differ in the wavelengths of light they absorb; they are usually called short or blue, middle or green, and long or red. Cones are used primarily to distinguish color and other features of the visual world at normal levels of light
Many mobile devices feature a dock connector. The simplest form of the dock connector today takes the form of a simple cable with the dock connector on one end and a USB connector on the other. This cable only has the USB signals in the dock connector, but is sufficient to synchronize and charge the devices. At the other end of the spectrum, dock connectors are used to completely merge devices into a variety of accessories, both mechanically and electrically
Surface rendering is limited in that it will display only surfaces that meet a threshold density, and will display only the surface that is closest to the imaginary viewer. In volume rendering, transparency and colors are used to allow a better representation of the volume to be shown in a single image. For example, the bones of the pelvis could be displayed as semi-transparent, so that, even at an oblique angle, one part of the image does not conceal another
Atmospheric dispersion modeling is the mathematical simulation of how air pollutants disperse in the ambient atmosphere. It is performed with computer programs that solve the mathematical equations and algorithms which simulate the pollutant dispersion. The dispersion models are used to estimate or to predict the downwind concentration of air pollutants or toxins emitted from sources such as industrial plants, vehicular traffic or accidental chemical releases
For example, spray towers are used to remove HCl gas from the tail-gas exhaust in manufacturing hydrochloric acid. In the production of superphosphate used in manufacturing fertilizer, SiF4 and HF gases are vented from various points in the processes. Spray towers have been used to remove these highly soluble compounds. Spray towers are also used for odor removal in bone meal and tallow manufacturing industries by scrubbing the exhaust gases with a solution of KMnO4
The cel is an important innovation to traditional animation, as it allows some parts of each frame to be repeated from frame to frame, thus saving labor. A simple example would be a scene with two characters on screen, one of which is talking and the other standing silently. Since the latter character is not moving, it can be displayed in this scene using only one drawing, on one cel, while multiple drawings on multiple cels are used to animate the speaking character
Various technologies exist for making paints that change color. Thermochromic paints and coatings contain materials that change conformation when heat is applied, and so they change color. Liquid crystals have been used in such paints, such as in the thermometer strips and tapes used in aquaria. Photochromic paints and coatings contain dyes that change conformation when the film is exposed to UV light, and so they change color. These materials are used to make eyeglasses
After this, data is output in PHP format. The backend is written in Java and Thrift is used as the messaging format so PHP programs can query Java services. Caching solutions are used to make the web pages display more quickly. The more and longer data is cached the less realtime it is. The data is then sent to MapReduce servers so it can be queried via Hive. This also serves as a backup plan as the data can be recovered from Hive. Raw logs are removed after a period of time
Much of the electronic old and new media used by commercial artists is multimedia. Exciting presentations are used to grab and keep attention in advertising. Business to business, and interoffice communications are often developed by creative services firms for advanced multimedia presentations beyond simple slide shows to sell ideas or liven-up training. Commercial multimedia developers may be hired to design for governmental services and nonprofit services applications as well
A dry or semi-dry scrubbing system, unlike the wet scrubber, does not saturate the flue gas stream that is being treated with moisture. In some cases no moisture is added, while in others only the amount of moisture that can be evaporated in the flue gas without condensing is added. Therefore, dry scrubbers do generally not have a stack steam plume or wastewater handling / disposal requirements. Dry scrubbing systems are used to remove acid gases primarily from combustion sources
The Ape Escape series is notable from its radical departure from the tried-and-true control method in most other games. It was the first PlayStation game to require the use of a DualShock controller; the left stick moves the character while the right operates whatever gadget the player has in his / her possession. Again, unlike many games which use to jump, both the R1 and R2 buttons are used, while the'shape ' buttons are used to cycle through the available items in the inventory
The Kōji molds are a group of Aspergillus species, notably Aspergillus oryzae, and secondarily A. sojae, that have been cultured in eastern Asia for many centuries. They are used to ferment a soybean and wheat mixture to make soybean paste and soy sauce. Koji molds break down the starch in rice, barley, sweet potatoes, etc., a process called saccharification, in the production of sake, shōchū and other distilled spirits. Koji molds are also used in the preparation of Katsuobushi
Due to the empirical nature of electronics theory, laboratory experimentation is an important part of the study of electronics. These experiments are used to prove, verify, and reinforce laws and theorems such as Ohm's law, Kirchhoff's laws, etc. Historically, electronics labs have consisted of electronics devices and equipment located in a physical space, although in more recent years the trend has been towards electronics lab simulation software, such as CircuitLogix, Multisim, and PSpice
The concept of genre is often applied, sometimes rather loosely, to other media with an artistic element, such as video game genres. Genre, and numerous minutely divided sub-genres, affect popular culture very significantly, not least as they are used to classify it for publicity purposes. The vastly increased output of popular culture in the age of electronic media encourages dividing cultural products by genre to simplify the search for products by consumers, a trend the internet has only intensified
Simple machines are elementary examples of kinematic chains or linkages that are used to model mechanical systems ranging from the steam engine to robot manipulators. The bearings that form the fulcrum of a lever and that allow the wheel and axle and pulleys to rotate are examples of a kinematic pair called a hinged joint. Similarly, the flat surface of an inclined plane and wedge are examples of the kinematic pair called a sliding joint. The screw is usually identified as its own kinematic pair called a helical joint
Multiple social gadgets are used to enable Friend Connect interaction. These include Social Bar, Comments, Ratings and Reviews, Featured Content, Interests ' Poll, Recommendations, Events and Games. In June 2009 Google added ClackPoint as a gadget. ClackPoint mixes live text chat, conference calling and document sharing. Status icons in the gadget mean that users can see who is dialed in and who is talking, and can poke or mute themselves or each other and a shared notepad allows multiple users to edit instantaneously
Primary explosives are often used in detonators or to trigger larger charges of less sensitive secondary explosives. Primary explosives are commonly used in blasting caps and percussion caps to translate a physical shock signal. In other situations, different signals such as electrical / physical shock, or in the case of laser detonation systems, light, are used to initiate an action, i.e., an explosion. A small quantity, usually milligrams, is sufficient to initiate a larger charge of explosive that is usually safer to handle
Since influenza spreads through both aerosols and contact with contaminated surfaces, surface sanitizing may help prevent some infections. Alcohol is an effective sanitizer against influenza viruses, while quaternary ammonium compounds can be used with alcohol so that the sanitizing effect lasts for longer. In hospitals, quaternary ammonium compounds and bleach are used to sanitize rooms or equipment that have been occupied by patients with influenza symptoms. At home, this can be done effectively with a diluted chlorine bleach
In the Legend of Spyro series, gems are used as powerups themselves; Red are collected to fill up Spyro's health bar, green are used to power his breath attacks, purple to power his fury attacks, and blue to upgrade his abilities in the main menu. In The Eternal Night, Dragon Relics are collectibles used to upgrade Spyro's health and magic bars, while Scriber's Quills are collectible items used to unlock concept art. Dragon Armor are collectibles in Dawn of the Dragon used to give Spyro and Cynder additional abilities in combat
Some digital video recorders can now record to solid state flash memory cards. They generally use Secure Digital cards, can include wireless connections (Bluetooth and Wi-Fi), and can play SWF files. There are some digital video recorders that combine video and graphics in real time to the flash card, called DTE or "direct to edit". These are used to speed-up the editing workflow in video and television production, since linear videotapes do not then need to be transferred to the edit workstation (see Non-linear editing system)
Many newer[vague] vehicles do not have air injection systems. Instead, they provide a constantly varying air-fuel mixture that quickly and continually cycles between lean and rich exhaust. Oxygen sensors are used to monitor the exhaust oxygen content before and after the catalytic converter and this information is used by the Electronic control unit to adjust the fuel injection so as to prevent the first catalyst from becoming oxygen-loaded while ensuring the second (HC and CO oxidization) catalyst is sufficiently oxygen-saturated
Three differently arranged styles of 2D diagrams are used to represent different aspects of the sequence ad structure relationships that confer specific physical and interaction properties on individual α-helices. Two of these emphasize circular placement around the cylindrical cross-section: the first-developed such diagram is called the "helical wheel", and a more recent version is called the "wenxiang diagram". The latter name came from the fact that it resembles a coil-like incense used in China to repel mosquitos; Chinese 蚊香
The energy for the formation of scrubbing droplets comes from the injected liquid. The high pressure sprays passing through the venturi throat form numerous fine liquid droplets that provide turbulent mixing between the gas and liquid phases. Very high liquid-injection rates are used to provide the gas-moving capability and higher collection efficiencies. As with other types of venturis, a means of separating entrained liquid from the gas stream must be installed. Entrainment separators are commonly used to remove remaining small droplets
The shot put ball is made of different kinds of materials depending on its intended use. Materials used include iron, cast iron, solid steel, stainless steel, brass, and synthetic materials like polyvinyl. Some metals are more dense than others making the size of the shot vary, for example, indoor shots are larger than outdoor shots, so different materials are used to make them. There are various size and weight standards for the implement that depend on the age and gender of the competitors as well as the national customs of the governing body
Interventions include intravenous medications, aerosolized medications, and positive-pressure therapy, including mechanical ventilation. Often multiple therapies are used to reverse the effects of status asthmaticus as rapidly as possible; though typically only one or two therapies are ultimately necessary, the permanent or generally long-term damage done by the airway restriction is a concern of clinicians. Intravenous and aerosolized treatments such as corticosteroids, and methylxanthines are often given. Magnesium sulfate is also commonly administered
Mass-distributed pornography is as old as the modern printing press. Almost as soon as photography was invented, it was being used to produce pornographic images. Some claim that pornography has been a driving force in the development of technologies from the printing press, through photography, to satellite TV, other forms of video, and the Internet. With the invention of tiny cameras and wireless equipments voyeur pornography is gaining ground. Mobile cameras are used to capture pornographic photos or videos, and forwarded as MMS, a practice known as sexting
At Nintendo's E3 press conference on June 15, 2010, the new Nintendo 3DS handheld console was revealed. At the conference Nintendo listed a number of publishers and franchises coming to the 3DS, one of whom was Activision with DJ Hero 3D, a new installment in the DJ Hero series and the first handheld DJ Hero title. The gameplay is similar in nature to DJ Hero, where the stylus and touchscreen are used to mimic scratching and crossfading between songs. It is unknown if the game is still in development after Activision stopped production of the Guitar Hero franchise
Diesel fuel is also prone to waxing or gelling in cold weather; both are terms for the solidification of diesel oil into a partially crystalline state. The crystals build up in the fuel line, eventually starving the engine of fuel and causing it to stop running. Low-output electric heaters in fuel tanks and around fuel lines are used to solve this problem. Also, most engines have a spill return system, by which any excess fuel from the injector pump and injectors is returned to the fuel tank. Once the engine has warmed, returning warm fuel prevents waxing in the tank
Request routing directs client requests to the content source best able to serve the request. This may involve directing a client request to the service node that is closest to the client, or to the one with the most capacity. A variety of algorithms are used to route the request. These include Global Server Load Balancing, DNS-based request routing, Dynamic metafile generation, HTML rewriting, and anycasting. Proximity—choosing the closest service node—is estimated using a variety of techniques including reactive probing, proactive probing, and connection monitoring
For drinking water, biological water treatment involves the use of naturally occurring micro-organisms in the surface water to improve water quality. Under optimum conditions, including relatively low turbidity and high oxygen content, the organisms break down material in the water and thus improve water quality. Slow sand filters or carbon filters are used to provide a place on which these micro-organisms grow. These biological treatment systems effectively reduce water-borne diseases, dissolved organic carbon, turbidity and colour in surface water, improving overall water quality
If investigations confirm NSCLC, the stage is assessed to determine whether the disease is localized and amenable to surgery or if it has spread to the point where it cannot be cured surgically. CT scan and positron emission tomography are used for this determination. If mediastinal lymph node involvement is suspected, mediastinoscopy may be used to sample the nodes and assist staging. Blood tests and pulmonary function testing are used to assess whether a person is well enough for surgery. If pulmonary function tests reveal poor respiratory reserve, surgery may not be a possibility
The most consistent aspect of therapy in cystic fibrosis is limiting and treating the lung damage caused by thick mucus and infection, with the goal of maintaining quality of life. Intravenous, inhaled, and oral antibiotics are used to treat chronic and acute infections. Mechanical devices and inhalation medications are used to alter and clear the thickened mucus. These therapies, while effective, can be extremely time-consuming for the patient. One of the most important battles that CF patients face is finding the time to comply with prescribed treatments while balancing a normal life
IMDb indicates that submitted ratings are filtered and weighted in various ways in order to produce a weighted mean that is displayed for each film, series, and so on. It states that filters are used to avoid ballot stuffing; the method is not described in detail to avoid attempts to circumvent it. In fact, it sometimes produces an extreme difference between the weighted average and the arithmetic mean. For example, Jonas Brothers: The 3D Concert Experience is considered to be the worst film with a weighted average of 1.3 as of March 2009, but has a rather ordinary arithmetic mean of 4.1
The word da, desu (polite) is the copula verb. It corresponds approximately to the English be, but often takes on other roles, including a marker for tense, when the verb is conjugated into its past form datta, deshita (polite) . This comes into use because only i-adjectives and verbs can carry tense in Japanese. Two additional common verbs are used to indicate existence ("there is") or, in some contexts, property: aru (negative nai) and iru (negative inai), for inanimate and animate things, respectively. For example, Neko ga iru "There's a cat", Ii kangae-ga nai "[I] haven ' t got a good idea"
Although WHO dropped its commitment to a global malaria eradication campaign in the 1970s as too ambitious, it retains a strong commitment to malaria control. WHO's Global Malaria Programme works to keep track of malaria cases, and future problems in malaria control schemes. WHO is to report, likely in 2015, as to whether RTS, S / AS01, currently in research, is a viable malaria vaccine. For the time being, insecticide-treated mosquito nets and insecticide sprays are used to prevent the spread of malaria, as are antimalarial drugs – particularly to vulnerable people such as pregnant women and young children
On the top of the controller is a row of four numbered LEDs, which are used to identify and distinguish multiple wireless controllers. These are similar to the indicators found on the Wii remote and the ring of light Xbox 360 Controller. Since the PlayStation 3 supports up to 7 controllers, but the controller only features 4 LEDs, controllers 5, 6 and 7 are represented as the sum of two other indicators. Sony has also patented a technology to be able to track the motion of these LEDs with the PlayStation Eye camera, for use alongside the PlayStation Move Controller, but it remains to be seen if this will be put to use
The most common fissile nuclear fuels are uranium-235 and plutonium-239 (239Pu) . The actions of mining, refining, purifying, using, and ultimately disposing of nuclear fuel together make up the nuclear fuel cycle. Not all types of nuclear fuels create power from nuclear fission. Plutonium-238 and some other elements are used to produce small amounts of nuclear power by radioactive decay in radioisotope thermoelectric generators and other types of atomic batteries. Also, light nuclides such as tritium (3H) can be used as fuel for nuclear fusion. Nuclear fuel has the highest energy density of all practical fuel sources
Australian Apprenticeships encompass all apprenticeships and traineeships. They cover all industry sectors in Australia and are used to achieve both ' entry-level ' and career ' upskilling ' objectives. There were 470, 000 Australian Apprentices in-training as at 31 March 2012, an increase of 2.4% from the previous year. Australian Government employer and employee incentives may be applicable, while State and Territory Governments may provide public funding support for the training element of the initiative. Australian Apprenticeships combine time at work with formal training and can be full-time, part-time or school-based
Another linear control track, at the tape's upper edge, holds pulses that mark the beginning of every frame of video; these are used to fine-tune the tape speed during playback and to get the rotating heads exactly on their helical tracks rather than having them end up somewhere between two adjacent tracks. Since good tracking depends on the exact distance between the rotating drum and the fixed control / audio head reading the linear tracks, which usually varies by a couple of micrometers between machines due to manufacturing tolerances, most VCRs offer tracking adjustment, either manual or automatic, to correct such mismatches
This process is the same for both character animation and special effects animation, which on most high-budget productions are done in separate departments. Effects animators animate anything that moves and is not a character, including props, vehicles, machinery and phenomena such as fire, rain, and explosions. Sometimes, instead of drawings, a number of special processes are used to produce special effects in animated films; rain, for example, has been created in Disney animated films since the late-1930s by filming slow-motion footage of water in front of a black background, with the resulting film superimposed over the animation
Several mechanical techniques are used to dislodge sputum and encourage its expectoration. In the hospital setting, chest physiotherapy is utilized; a respiratory therapist percusses an individual's chest with his or her hands several times a day, to loosen up secretions. Devices that recreate this percussive therapy include the ThAIRapy Vest and the intrapulmonary percussive ventilator (IPV) . Newer methods such as Biphasic Cuirass Ventilation, and associated clearance mode available in such devices, integrate a cough assistance phase, as well as a vibration phase for dislodging secretions. These are portable and adapted for home use
A ship may also have one or more slots for rigs, modules that require no power grid or CPU, but instead require a ship resource called calibration. Installing a rig is a semi-permanent action, as a rig cannot be removed from the ship without being destroyed. Rigs come in three sizes: small, medium, and large, which roughly correspond to the size of the ship, and are used to affect other aspects of the ship such as maximum speed or cargo capacity, or to augment the capabilities of other modules installed in the ship. Most rigs also incur a penalty to certain aspect of the ship; for example armor rigs reduce the maximum velocity of the ship
A pair of inertial sensors inside the controller, a three-axis linear accelerometer and a three-axis angular rate sensor, are used to track rotation as well as overall motion. An internal magnetometer is also used for calibrating the controller's orientation against the Earth's magnetic field to help correct against cumulative error by the inertial sensors. In addition, an internal temperature sensor is used to adjust the inertial sensor readings against temperature effects. The inertial sensors can be used for dead reckoning in cases which the camera tracking is insufficient, such as when the controller is obscured behind the player's back
Theatre is a collaborative form of fine art that uses live performers to present the experience of a real or imagined event before a live audience in a specific place. The performers may communicate this experience to the audience through combinations of gesture, speech, song, music or dance. Elements of design and stagecraft are used to enhance the physicality, presence and immediacy of the experience. The specific place of the performance is also named by the word "theatre" as derived from the Ancient Greek θέατρον (théatron, “ a place for viewing ”), itself from θεάομαι (theáomai, “ to see", "to watch", "to observe ”)
Diagnosis of infectious disease is nearly always initiated by medical history and physical examination. More detailed identification techniques involve the culture of infectious agents isolated from a patient. Culture allows identification of infectious organisms by examining their microscopic features, by detecting the presence of substances produced by pathogens, and by directly identifying an organism by its genotype. Other techniques are used to produce images of internal abnormalities resulting from the growth of an infectious agent. The images are useful in detection of, for example, a bone abscess or a spongiform encephalopathy produced by a prion
A wet scrubber's ability to collect small particles is often directly proportional to the power input into the scrubber. Low energy devices such as spray towers are used to collect particles larger than 5 micrometers. To obtain high efficiency removal of 1 micrometer particles generally requires high energy devices such as venturi scrubbers or augmented devices such as condensation scrubbers. Additionally, a properly designed and operated entrainment separator or mist eliminator is important to achieve high removal efficiencies. The greater the number of liquid droplets that are not captured by the mist eliminator the higher the potential emission levels
Drawing is a means of making an image, using any of a wide variety of tools and techniques. It generally involves making marks on a surface by applying pressure from a tool, or moving a tool across a surface. Common tools are graphite pencils, pen and ink, inked brushes, wax color pencils, crayons, charcoals, pastels, and markers. Digital tools which can simulate the effects of these are also used. The main techniques used in drawing are: line drawing, hatching, crosshatching, random hatching, scribbling, stippling, and blending. An artist who excels in drawing is referred to as a draftswoman or draughtsman. Drawings are used to create comics and animation for example
Although Gran Turismo has an arcade mode, most gameplay derives from its simulation mode. Players start with a certain number of credits, usually 10, 000, which are used to purchase vehicles from several manufacturer-specific shops, or from used car dealers, and then tune their car at the appropriate parts store for best performance. Certain events are open only to particular types of vehicles. In order to enter and progress through more difficult races, a license-testing system has been implemented, which guides players through skill development. Players may apply prize money won in events to upgrade their existing car or buy a new one, collecting a garage of vehicles
Emerging forms of feminism and feminist art of the time was particularly influential to activist art. The idea that “ the personal is the political ”, that is, the notion that personal revelation through art can be a political tool, guided much activist art in its study of the public dimensions to private experience. The strategies deployed by feminist artists parallel those by artists working in activist art. Such strategies often involved “ collaboration, dialogue, a constant questioning of aesthetic and social assumptions, and a new respect for audience ” and are used to articulate and negotiate issues of self-representation, empowerment, and community identity
There are two basic methods of treating: with and without pressure. Non-pressure methods are the application of preservative by brushing, spraying or dipping the piece to be treated. Deeper, more thorough penetration is achieved by driving the preservative into the wood cells with pressure. Various combinations of pressure and vacuum are used to force adequate levels of chemical into the wood. Pressure-treating preservatives consist of chemicals carried in a solvent. Chromated copper arsenate, once the most commonly used wood preservative in North America began being phased out of most residential applications in 2004. Replacing it are amine copper quat and copper azole (CA)
Large scale cyclones are used in sawmills to remove sawdust from extracted air. Cyclones are also used in oil refineries to separate oils and gases, and in the cement industry as components of kiln preheaters. Cyclones are increasingly used in the household, as the core technology in bagless types of portable vacuum cleaners and central vacuum cleaners. Cyclones are also used in industrial and professional kitchen ventilation for separating the grease from the exhaust air in extraction hoods. Smaller cyclones are used to separate airborne particles for analysis. Some are small enough to be worn clipped to clothing, and are used to separate respirable particles for later analysis
Most times, a foreign language is spoken in film, subtitles are used to translate the dialogue for the viewer. However, there are occasions when foreign dialogue is left unsubtitled. This is often done if the movie is seen predominantly from the viewpoint of a particular character who does not speak the language. Such absence of subtitles allows the audience to feel a similar sense of incomprehension and alienation that the character feels. An example of this is seen in Not Without My Daughter. The Persian language dialogue spoken by the Iranian characters is not subtitled because the main character Betty Mahmoody does not speak Persian and the audience is seeing the film from her viewpoint
Garcia-Ballester says the following of Galen’s use of prognosis: "In modern medicine, we are used to distinguishing between the diagnostic judgment and the prognostic judgment (the conjecture about what will happen to him.) Galen, like the Hippocratics, was not. For him, to understand a clinical case technically, ‘to diagnose’, was among other things, to know with greater or lesser certainty the outcome fore the patient, ‘to prognosticate’. Prognosis, then, is one of the essential problems and most important objectives of Galenic diagnosis. Galen was concerned to distinguish it from divination or prophecy, both to improve diagnosis technically and to enhance the physician’s reputation."
While there is some controversy concerning the patenting of isolated genes and the way those patents are used, and there is controversy concerning patents on the diagnostic uses of genes, it is difficult to find controversy surrounding patents on genes that are used to manufacture therapeutic proteins (for an example of patents on therapeutic proteins, the drug candidate that is the subject of the early part of the movie ' Extraordinary Measures ' was covered in part by a classic gene patent, US Patent 6, 770, 468.) There is also little controversy concerning the role of gene patents in the chemical industry—for instance in the manufacture of enzymes used in consumer products or industrial processes
Resident Evil 4: Wii Edition was released for the Wii on May 31, 2007 in Japan and on June 19, 2007 in the United States. It features updated controls that utilize the pointing and motion-sensing abilities of the Wii Remote and Nunchuk, though both the GameCube controller and the Classic Controller are also supported. The Wii Remote is able to aim and shoot anywhere on the screen with a reticle that replaces the laser sight found in the other versions, and motion-based gestures are used to perform some context-sensitive actions, such as dodging or slashing Leon's knife. The Wii Edition also includes the extra content from the PS2 and PC versions, and a trailer for Resident Evil: The Umbrella Chronicles
Cryogens, like liquid nitrogen, are further used for specialty chilling and freezing applications. Some chemical reactions, like those used to produce the active ingredients for the popular statin drugs, must occur at low temperatures of approximately −100°C. Special cryogenic chemical reactors are used to remove reaction heat and provide a low temperature environment. The freezing of foods and biotechnology products, like vaccines, requires nitrogen in blast freezing or immersion freezing systems. Certain soft or elastic materials become hard and brittle at very low temperatures, which makes cryogenic milling (cryomilling) an option for some materials that cannot easily be milled at higher temperatures
Fire retardants are used to help slow wildfires, coat fuels, and lessen oxygen availability as required by various firefighting situations. They are composed of nitrates, ammonia, phosphates and sulfates, as well as other chemicals and thickening agents. The choice of whether to apply retardant depends on the magnitude, location and intensity of the wildfire. Fire retardants are used to reach inaccessible geographical regions where ground firefighting crews are unable to reach a wildfire or in any occasion where human safety and structures are in endangered. In certain instances, fire retardant may also be applied ahead of wildfires for protection of structures and vegetation as a precautionary fire defense measure
Once the accounts balance, the accountant makes a number of adjustments and changes the balance amounts of some of the accounts. These adjustments must still obey the double-entry rule. For example, the "inventory" account asset account might be changed to bring them into line with the actual numbers counted during a stock take. At the same time, the expense account associated with usage of inventory is adjusted by an equal and opposite amount. Other adjustments such as posting depreciation and prepayments are also done at this time. This results in a listing called the adjusted trial balance. It is the accounts in this list and their corresponding debit or credit balances that are used to prepare the financial statements
Early grain elevators and bins were often constructed of framed or cribbed wood, and were prone to fire. Grain elevator bins, tanks and silos are now usually constructed of steel or reinforced concrete. Bucket elevators are used to lift grain to a distributor or consignor, from where it falls through spouts and / or conveyors and into one of a number of bins, silos or tanks in a facility. When desired, silos, bins and tanks are emptied by gravity flow, sweep augers and conveyors. As grain is emptied from bins, tanks and silos it is conveyed, blended and weighted into trucks, railroad cars or barges, and shipped to grain wholesalers, exporters and / or local end-users, such as flour mills, breweries and ethanol or alcohol distilleries
Filters with activated carbon are usually used in compressed air and gas purification to remove oil vapors, odors, and other hydrocarbons from the air. The most common designs use a 1 stage or 2 stage filtration principle in which activated carbon is embedded inside the filter media. Activated carbon is also used in spacesuit Primary Life Support Systems. Activated carbon filters are used to retain radioactive gases from a nuclear boiling water reactor turbine condenser. The air vacuumed from the condenser contains traces of radioactive gases. The large charcoal beds adsorb these gases and retain them while they rapidly decay to non-radioactive solid species. The solids are trapped in the charcoal particles, while the filtered air passes through
Japanese is an agglutinative, mora-timed language with simple phonotactics, a pure vowel system, phonemic vowel and consonant length, and a lexically significant pitch-accent. Word order is normally subject–object–verb with particles marking the grammatical function of words, and sentence structure is topic–comment. Sentence-final particles are used to add emotional or emphatic impact, or make questions. Nouns have no grammatical number or gender, and there are no articles. Verbs are conjugated, primarily tense and voice, but not person. Japanese equivalents of adjectives are also conjugated. Japanese has a complex system of honorifics with verb forms and vocabulary to indicate the relative status of the speaker, the listener, and persons mentioned
The response of a tumor to radiation therapy is also related to its size. For complex reasons, very large tumors respond less well to radiation than smaller tumors or microscopic disease. Various strategies are used to overcome this effect. The most common technique is surgical resection prior to radiation therapy. This is most commonly seen in the treatment of breast cancer with wide local excision or mastectomy followed by adjuvant radiation therapy. Another method is to shrink the tumor with neoadjuvant chemotherapy prior to radical radiation therapy. A third technique is to enhance the radiosensitivity of the cancer by giving certain drugs during a course of radiation therapy. Examples of radiosensiting drugs include: Cisplatin, Nimorazole, and Cetuximab
Aside from landing gear brakes, most large aircraft have other ways of decelerating. In the context of aircraft, air brakes are aerodynamic surfaces that create friction with the airflow causing the vehicle to slow. These are usually implemented as flaps that oppose airflow when extended and are flush with aircraft when retracted. Reverse thrust is also a feature of many airplane engines. Propeller aircraft implement reverse thrust by reversing the pitch of the propellers, while jet aircraft implement it by redirecting their engine exhaust forward. On aircraft carriers, arresting gears are used to stop an aircraft instead of the above methods. Pilots may even apply full throttle on touchdown in case the arresting gear doesn ' t catch and a go around is needed
As performers have become interested in the instrument, harp makers such as Jay Witcher, David Kortier, Ardival Harps, Joël Herrou and others have begun building wire-strung harps. The traditional wire materials are used, however iron has been replaced by steel and the modern phosphor bronze has been added to the list. The phosphor bronze and brass are most commonly used. Steel tends to be very abrasive to the nails. Silver and gold are used to get high density materials into the bass courses of high quality clàrsachs to greatly improve their tone quality. In the period, no sharping devices were used. Harpers had to re-tune strings to change keys. This practice is reflected by most of the modern luthiers, yet some allow provisions for either levers or blades
Propellers are used to move through a fluid. Propellers have been used as toys since ancient times, however it was Leonardo da Vinci who devised what was one of the earliest propeller driven vehicles vehicles, the "aerial-screw". In 1661, Toogood & Hays adopted the screw for use as a ship propeller. Since then, the propeller has been tested on many terrestrial vehicles, including the Schienenzeppelin train and numerous cars. In modern times, propellers are most prevalent on watercraft and aircraft, as well as some amphibious vehicles such as hovercraft and ground effect vehicles. Intuitively, propellers cannot work in space as there is no working fluid, however some sources have suggested that since space is never empty, a propeller could be made to work in space
When infection attacks the body, anti-infective drugs can suppress the infection. Four types of anti-infective or drugs exist: antibacterial, antiviral, antitubercular, and antifungal. Depending on the severity and the type of infection, the antibiotic may be given by mouth, injection or may be applied topically. Severe infections of the brain are usually treated with intravenous antibiotics. Sometimes, multiple antibiotics are used to decrease the risk of resistance and increase efficacy. Antibiotics only work for bacteria and do not affect viruses. Antibiotics work by slowing down the multiplication of bacteria or killing the bacteria. The most common classes of antibiotics used in medicine include penicillin, cephalosporins, aminoglycosides, macrolides, quinolones and tetracyclines
Hydraulic excavators may be used to topple one- or two-story buildings by an undermining process. The strategy is to undermine the building while controlling the manner and direction in which it falls. The demolition project manager / supervisor will determine where undermining is necessary so that a building is pulled in the desired manner and direction. The walls are typically undermined at a building's base, but this is not always the case if the building design dictates otherwise. Safety and cleanup considerations are also taken into account in determining how the building is undermined and ultimately demolished. Hoe rams are typically used for removing the concrete road deck and piers during bridge demolition, while hydraulic shears are used to remove the bridge's structural steel
Video game genres are used to categorize video games based on their gameplay interaction rather than visual or narrative differences. A video game genre is defined by a set of gameplay challenges. They are classified independent of their setting or game-world content, unlike other works of fiction such as films or books. For example, an action game is still an action game, regardless of whether it takes place in a fantasy world or outer space. Within game studies there is a lack of consensus in reaching accepted formal definitions for game genres, some being more observed than others. Like any typical taxonomy, a video game genre requires certain constants. Most video games feature obstacles to overcome, so video game genres can be defined where obstacles are completed in substantially similar ways
Most modern sonographic machines use pulsed Doppler to measure velocity. Pulsed wave machines transmit and receive series of pulses. The frequency shift of each pulse is ignored, however the relative phase changes of the pulses are used to obtain the frequency shift. The major advantages of pulsed Doppler over continuous wave is that distance information is obtained (the time between the transmitted and received pulses can be converted into a distance with knowledge of the speed of sound) and gain correction is applied. The disadvantage of pulsed Doppler is that the measurements can suffer from aliasing. The terminology "Doppler ultrasound" or "Doppler sonography", has been accepted to apply to both pulsed and continuous Doppler systems despite the different mechanisms by which the velocity is measured
Attaching a small metal, rubber, leather, or wooden device called a mute, or sordino, to the bridge of the violin gives a softer, more mellow tone, with fewer audible overtones; the sound of an entire orchestral string section playing with mutes has a hushed quality. The conventional Italian markings for mute usage are con sord., or con sordina, meaning ' with mute ' ; and senza sord., meaning ' without mute ' ; or via sord., meaning ' mute off ' . Larger metal, rubber, or wooden mutes are widely available, known as practice mutes or hotel mutes. Such mutes are generally not used in performance, but are used to deaden the sound of the violin in practice areas such as hotel rooms. Some composers have used practice mutes for special effect, for example, at the end of Luciano Berio's Sequenza VIII for solo violin
Competitive pole vaulting began using solid ash poles. As the heights attained increased, the bamboo poles gave way to tubular aluminum, which was tapered at each end. Today's pole vaulters benefit from poles produced by wrapping pre-cut sheets of fiberglass that contains resin around a metal pole mandrel, to produce a slightly pre-bent pole that bends more easily under the compression caused by an athlete's take-off. The shape of the fiberglass sheets and the amount of fiberglass used is carefully planned to provide the desired length and stiffness of pole. Different fiber types, including carbon-fiber, are used to give poles specific characteristics intended to promote higher jumps. In recent years, carbon fiber has been added to the commonly used E-glass and S-glass materials to create a pole with a lighter carry weight
Another part of Dark Cloud's gameplay involves special items called Atla which are used to rebuild the world. These items, which are present in almost each dungeon level, are large spherical objects and can be retrieved only by the main character. When removed from the dungeon, they become pieces of the world. These pieces must then be placed through Georama mode, an element similar to city-building games, in which the player can arrange the pieces of the world onto the landscape. After villagers have been placed, the player can speak to them to discover what their wishes are for the rebuilding of the village. As the player approaches the ideals concerning the village restoration and its villagers ' preferences, their progress is recorded as a percentage of completion in the Georama menu. When the progress reaches 100%, the village is considered complete
Treatment, or voice rehabilitation, usually involves vocal training, speech therapy, and, occasionally, vocal rest. In rare cases, surgery may be required. Removal of vocal cord nodules is a relatively safe and minor surgery. However, those who sing professionally or otherwise should take serious consideration before having surgery as it can affect the ability to sustain notes, as well as alter the vocal range. Examples of this are Ryan Key, José José, and Julie Andrews, who lost much of their singing ability after undergoing vocal nodule surgery. While the patient is subdued under general anesthesia, long thin scissors and scalpels are used to remove the nodules, or CO2 surgical lasers might be used which are very effective in such cases. The best preventive steps seem to be wrapped up in the study of vocology, the science and practice of voice habilitation
The 1931 National Science Museum copy of the remaining film sequence shot in Roundhay garden features 20 frames. The digital version produced by the NMPFT has 52 frames (run time 2.11 seconds at 24.64 frame / s) and switches the left side and the right side, since the house is actually incorrectly shown on the right-hand side of the scene in the 1931 copy. It is believed to have been mirrored because of paper parts stuck on the left side of the film that would reduce the visibility. The reason is both physiologic and cultural, a Western viewer's eyes are used to automatically watch from top left to right, this reflex action comes from the childhood taught reading direction. The garden sequence film's damaged side results in distortion and deformation on the inverted, right side of the digital movie. The scene was shot in Le Prince's father-in-law's garden at Oakwood Grange, Roundhay on October 14, 1888
Air dispersion models are also used by public safety responders and emergency management personnel for emergency planning of accidental chemical releases. Models are used to determine the consequences of accidental releases of hazardous or toxic materials, Accidental releases may result fires, spills or explosions that involve hazardous materials, such as chemicals or radionuclides. The results of dispersion modeling, using worst case accidental release source terms and meteorological conditions, can provide an estimate of location impacted areas, ambient concentrations, and be used to determine protective actions appropriate in the event a release occurs. Appropriate protective actions may include evacuation or shelter in place for persons in the downwind direction. At industrial facilities, this type of consequence assessment or emergency planning is required under the Clean Air Act (CAA) codified in Part 68 of Title 40 of the Code of Federal Regulations
X-rays are used to produce the diffraction pattern because their wavelength λ is typically the same order of magnitude as the spacing d between planes in the crystal. In principle, any wave impinging on a regular array of scatterers produces diffraction, as predicted first by Francesco Maria Grimaldi in 1665. To produce significant diffraction, the spacing between the scatterers and the wavelength of the impinging wave should be similar in size. For illustration, the diffraction of sunlight through a bird's feather was first reported by James Gregory in the later 17th century. The first artificial diffraction gratings for visible light were constructed by David Rittenhouse in 1787, and Joseph von Fraunhofer in 1821. However, visible light has too long a wavelength (typically, 5500 angstroms) to observe diffraction from crystals. Prior to the first X-ray diffraction experiments, the spacings between lattice planes in a crystal were not known with certainty
Snake venom consists of many different toxin proteins: these can either have enzymatic activity, which typically assists in digestion, or can be shorter peptides that are used to immobilize prey. Toxin proteins make up many multigene families, and arose from gene recruitment of proteins that do not code for toxins, followed by extensive evolutionary modification. Toxin evolution follows the birth-and-death model of gene families, where duplication followed by functional diversification results in the creation of structurally related proteins that have slightly different functions. It is thought that venom as a way to immobilize prey was beneficial in allowing the uncoupling of feeding system and locomotion, which are coupled in the Haenophidians, which then enabled snakes with venom systems to colonize open areas. Venom continue to evolve as specific toxins are modified to target a specific prey, and it is found that toxins vary according to diet in some species
