- Over the active dynamic range of most films, the density of the developed film is proportional to the logarithm of the total amount of light to which the film was exposed, so the transmission coefficient of the developed film is proportional to a power of the reciprocal of the brightness of the original exposure. This is due to the statistics of grain activation: as the film becomes progressively more exposed, each incident photon is less likely to impact a still-unexposed grain, yielding the logarithmic behavior. A simple, idealized statistical model yields the equation density = 1 - light, where light is proportional to the number of photons hitting a unit area of film, k is the probability of a single photon striking a grain ( based on the size of the grains and how closely spaced they are ), and density is the proportion of grains that where hit by at least one photon
- A 2004 cross-Europe study found that approximately one in four people reported meeting criteria at some point in their life for at least one of the DSM-IV disorders assessed, which included mood disorders, anxiety disorders ( 13.6% ) or alcohol disorder ( 5.2% ) . Approximately one in ten met criteria within a 12-month period. Women and younger people of either gender showed more cases of disorder. A 2005 review of surveys in 16 European countries found that 27% of adult Europeans are affected by at least one mental disorder in a 12 month period
- After the announcement and release of the third generation iPad, the iPad 2, which continues to be available for purchase received a hardware upgrade. The upgraded variant of the iPad 2 features a smaller version of the Apple A5 SoC, which is able to reduce battery consumption. Benchmark tests conducted by Anandtech concluded that the upgraded variant is able to last longer by at least an hour and a half, depending on the task that is conducted on the device. The maximum temperature that the device heated up to was also less than original iPad 2, tests conducted by the same organisation revealed that the upgraded variant was able to operate at 1 degrees lower when performing intensive tasks. Performance difference between the two variants, according Anandtech is negligible
- The most common form of chromosomal crossover is homologous recombination, where the two chromosomes involved share very similar sequences. Non-homologous recombination can be damaging to cells, as it can produce chromosomal translocations and genetic abnormalities. The recombination reaction is catalyzed by enzymes known as recombinases, such as RAD51. The first step in recombination is a double-stranded break caused by either an endonuclease or damage to the DNA. A series of steps catalyzed in part by the recombinase then leads to joining of the two helices by at least one Holliday junction, in which a segment of a single strand in each helix is annealed to the complementary strand in the other helix. The Holliday junction is a tetrahedral junction structure that can be moved along the pair of chromosomes, swapping one strand for another. The recombination reaction is then halted by cleavage of the junction and re-ligation of the released DNA
- While still officially working with the Poor Law, Chadwick took up the question of sanitation in conjunction with Dr Thomas Southwood Smith. Their joint efforts produced a salutary improvement in the public health. His report on The Sanitary Condition of the Labouring Population was researched and published at his own expense. A supplementary report was also published in 1843. Chadwick's efforts were acknowledged by at least one health reformer of the day: William James Erasmus Wilson dedicated his 1854 book Healthy Skin to Chadwick "In admiration of his strenuous and indefatigable labors in the cause of Sanitary Reform"
- Nasal blockage is determined by at least two factors: 1 ) the size of the adenoids, and 2 ) the size of the nasal pharynx passageway. The adenoid usually reaches its greatest size by about age 5 years or so, and then fades away by late childhood - generally by the age of 7 years. The lymphoid tissue remains under the mucosa of the nasopharynx, and could be seen under a microscope if the area was biopsied, but the mass is so reduced in size that the roof of the nasopharynx becomes flat rather than mounded. Just as the size of the adenoids is variable between individuals, so is the age at which adenoids atrophy
- In the United States, pediatric pulmonologists are physicians who, after receiving a medical degree, complete residency training in pediatrics, followed by at least three additional years of subspeciality fellowship training in pulmonology
- Andorra's first match in a FIFA-sanctioned competition was a 3–1 loss to Armenia on 5 September 1998 in a qualifier for UEFA Euro 2000. Andorra lost all ten qualifiers for the tournament. The team particularly struggled in away matches; each loss was by at least three goals. Andorra scored only three goals, two of which were penalties, and two of which were in the away matches. Andorra conceded 28 goals, and their biggest defeat of the qualifiers was a 6–1 away loss to Russia
- In the United States, pulmonologists are physicians who, after receiving a medical degree, complete residency training in internal medicine, followed by at least two additional years of subspeciality fellowship training in pulmonology. After satisfactorily completing a fellowship in pulmonary medicine, the physician is permitted to take the board certification examination in pulmonary medicine. After passing this exam, the physician is then board certified as a pulmonologist. Most pulmonologists complete three years of combined subspecialty fellowship training in pulmonary medicine and critical care medicine
- Former Real Madrid coach Miguel Muñoz, who had temporarily coached Spain in 1969, returned to coach the national team. Spain was in Euro 84 qualifying Group 7, against The Netherlands, Republic of Ireland, Iceland, and Malta. Entering the last match, Spain needed to defeat Malta by at least 11 goals to surpass the Netherlands for the top spot in the group, and after leading 3–1 at half time, Spain scored nine goals in the second half to win by 12–1 and win the group. In the final tournament, Spain was drawn into group B with Romania, Portugal, and West Germany. After 1–1 draws against their first two opponents, Spain topped the group by virtue of a 1–0 victory against West Germany. The semifinals saw Spain and Denmark drawn at 1–1 after extra time, before Spain proceeded by virtue of winning the penalty shootout 5–4 on penalties. Hosts and tournament favourites France defeated Spain 2–0 in the final after a goalless first half
- Myriad's appeal was granted, and the case was heard in United States Court of Appeals for the Federal Circuit. Myriad, the defendant-appellant, was supported by at least 15 amicus briefs and the plaintiff-appellees ' position received support from 12 amicus briefs. The Department of Justice provided a surprising and unsolicited brief that in part supported the appellees but also suggested that claims covering isolated naturally occurring human genetic sequences are not properly patentable. Oral arguments were held on April 4, 2011
