Lutra is a genus of otters, one of seven in the subfamily Lutrinae. The genus includes these recent species: The genus most evolved in Asia during the late Pliocene epoch. Lutra species are semiaquatic mammals, so they are well-adapted to both water and land, they prefer shallow, narrow areas of streams surrounded by mature trees and with rocks where weirs reduce the flow of the water, as well as attract fishes. They seem to tolerate roads and residential and agricultural areas, but only moderate human interaction, they avoid areas without vegetation cover and rocks. The otters' diets consist of fish. However, during the winter and in colder environments, fish consumption is lower and the otters use other resources for their food supply, their diets can consist of amphibians, bird predation, small rodents, invertebrates such as water beetles and crayfish. They have feed on plants grasses. With this large diversity of prey and resources for their diets, otters are considered "opportunistic eaters".

Some otters live in solitude, while others live in groups

Thomas Cromwell (Parliamentary diarist)

Thomas Cromwell, was an English Member of Parliament during the reign of Queen Elizabeth I. His diaries of proceedings in the House of Commons are an important source for historians of parliamentary history during the period when he was a member, Sir John Neale draws upon them in his ground-breaking two-volume study of Elizabeth I and Her Parliaments. Thomas Cromwell was the third son of Gregory Cromwell, 1st Baron Cromwell and Elizabeth Seymour, sister to Jane Seymour, third wife of Henry VIII, he was the grandson of statesman Thomas Cromwell, 1st Earl of Essex, chief minister to Henry VIII. Born in around 1540, he was educated at St John's College, Cambridge where he matriculated in 1553. Cromwell was a member of five successive Parliaments between 1571 and 1589 during the reign of Queen Elizabeth I, his constituencies included Fowey and Grampound. Gregory Cromwell had been a friend of Sir William Cecil, who he described in his will as my especial and singular good lord, it may have been Cecil who found Thomas Cromwell his seats at Fowey and Grampound.

His return at Preston in 1584 may be accounted for by the patronage of Sir Ralph Sadler, chancellor of the Duchy of Lancaster, brought up in the household of Cromwell’s grandfather. He served on numerous Parliamentary committees and, by the end of his career, seems to have been one of the most respected of the independent members and recognised as an authority on Parliamentary procedure, his sympathies were with the Puritan party in the House. Neale described him as the model type of parliamentarian versed in the history and procedure of the institution, though lacking in historical perspective, he was a puritan but his zeal did not cloud his judgment which, with his knowledge of procedure, rendered him one of the most experienced committeemen of his time. Thomas Cromwell married, on 18 Aug 1580, daughter of Thomas Gardner of Coxford, by her had 5 sons and 4 daughters. Henry Cromwell Humfrey Cromwell Ann Cromwell Susan Cromwell Lyonell Cromwell Thomas Cromwell Gregory Cromwell Katherine Cromwell Mary Cromwell After retiring from Parliament, Cromwell resided at King’s Lynn, making his will on 17 Feb. 1610.

Cromwell requested that no "pomp or sumptuousness" be used at his funeral, "being not willing to have vanities continued for me after my death, whereto I have been too much subject in my lifetime." He died between February 1610 and April 1611, leaving money and property to his wife "who has always been a most loving wife... and hath besides endured many griefs and sorrows for my sake", to his children, subject to their good behaviour and money to the poor of Great Risborough, to the poor of the parish where he died.

Ratio distribution

A ratio distribution is a probability distribution constructed as the distribution of the ratio of random variables having two other known distributions. Given two random variables X and Y, the distribution of the random variable Z, formed as the ratio Z = X/Y is a ratio distribution. An example is the Cauchy distribution, which comes about as the ratio of two distributed variables with zero mean. Two other distributions used in test-statistics are ratio distributions: the t-distribution arises from a Gaussian random variable divided by an independent chi-distributed random variable, while the F-distribution originates from the ratio of two independent chi-squared distributed random variables. More general ratio distributions have been considered in the literature; the ratio distributions are heavy-tailed, it may be difficult to work with such distributions and develop an associated statistical test. A method based on the median has been suggested as a "work-around"; the ratio is one type of algebra for random variables: Related to the ratio distribution are the product distribution, sum distribution and difference distribution.

More one may talk of combinations of sums, differences and ratios. Many of these distributions are described in Melvin D. Springer's book from 1979 The Algebra of Random Variables; the algebraic rules known with ordinary numbers do not apply for the algebra of random variables. For example, if a product is C = AB and a ratio is D=C/A it does not mean that the distributions of D and B are the same. Indeed, a peculiar effect is seen for the Cauchy distribution: The product and the ratio of two independent Cauchy distributions will give the same distribution; this becomes evident when regarding the Cauchy distribution as itself a ratio distribution of two Gaussian distributions: Consider two Cauchy random variables, C 1 and C 2 each constructed from two Gaussian distributions C 1 = G 1 / G 2 and C 2 = G 3 / G 4 C 1 C 2 = G 1 / G 2 G 3 / G 4 = G 1 G 4 G 2 G 3 = G 1 G 2 × G 4 G 3 = C 1 × C 3, where C 3 = G 4 / G 3. The first term is the ratio of two Cauchy distributions while the last term is the product of two such distributions.

A way of deriving the ratio distribution of Z from the joint distribution of the two other random variables, X and Y, is by integration of the following form p Z = ∫ − ∞ + ∞ | y | p X, Y d y. This may not be straightforward. By way of example take the classical problem of the ratio of two standard Gaussian samples; the joint pdf is p X, Y = 1 2 π exp ⁡ exp ⁡ Defining Z = X / Y we have p Z = 1 2 π ∫ − ∞ ∞ | y | exp ⁡ exp ⁡ d y = 1 2 π ∫ − ∞ ∞ | y | exp ⁡ d y {\displaystyle \.

Guillermo Cifré

Guillermo Cifré Figuerola, known by his first name, Cifré, was a Spanish cartoonist and animator, creator of some of the most representative characters of the "Bruguera school", such as El repórter Tribulete and Don Furcio Buscabollos, about an unlucky knight and his talking mare in a pseudo-medieval world. Some of his characters were the old bachelor type such as Golondrino Pérez; as a result, he is considered one of the "Big Five" of that editorial of the 1950s, along with Conti, Giner and Peñarroya. He was the father of cartoonist Guillem Cifré. Figuerola was born in Castellón, his professional career began, along with other future artists of Bruguera, in the studios of Dibujos Animados Chamartín, where he participated in the production of series like Civilón and Garabatos In 1947 he began working for Bruguera publishing, creating the series El repórter Tribulete, que en todas partes se mete, Las tremebundas fazañas de Don Furcio Buscabollos, Cucufato Pi and Amapolo Nevera for magazines "Pulgarcito" and "El DDT".

At this time, he worked with his friends Escobar in a rented studio. They liked to catch red pine mushrooms in joke about it among themselves. Cifré was a big fan of football and painting, his son Guillem was born in 1952. In 1957, together with these and other cartoonist of Bruguera, Carlos Conti and Eugenio Giner, he created an independent company that began publishing a new journal, Tío Vivo, keeping the typical schemes of Bruguera magazines. For this magazine, Cifré draw new characters, such as Golondrino Pérez, Rosalía and El sabio Megatón, all in 1957. After the economic failure of Tío Vivo, he returned to Bruguera, for which continued creating characters, such as Pepe Despiste, Cepillo Chivátez and Don Tele, he died in Barcelona. According to researcher Luis Gasca, Guillermo Cifré was "the most successful maintainer of Pulgarcito style, his iconographic types and style served as inspiration for future artists. Armando Matías Guiu considers him one of the three main artists of the Bruguera style alongside Conti and Escobar.

10Kh was the designation for the initial series of Soviet Union pulse jet engine powered air-launched cruise missiles, reverse engineered from the Fieseler Fi 103 flying bomb, developed in the 1950s by OKB-52 under the leadership of Vladimir Nikolaevič Čelomej and cancelled in the same decade. Reports of the German V-1 flying bomb attacks on London prompted Stalin to initiate a programme to develop a Soviet equivalent, commencing in June 1944. Vladimir Chelomey, working on pulse jet engines, was assigned to the project in October 1944 and given control of OKB-52; the programme was assisted by the partial recovery of a V-1 by Soviet forces at the Blizna test range in Poland. The initial V-1 copy was called 10Kh and Izdeliye 10. Serial production was scheduled to commence in March 1945 with 100 per month, increasing to 450 per month that year. By the end of 1944 the development of the D-3 pulse engine that propelled the 10Kh was at the prototype stage and the first production 10Kh was ready on 5 February 1945.

As no launching ramps had been constructed, the first test was an air launch from a Petlyakov Pe-8 heavy bomber on 20 March 1945, near Tashkent. By 25 July, 66 missiles had been launched, of which 44 transitioned to autonomous flight, 22 of these reaching the range target and 20 maintaining the required heading. A batch of improved 10Kh were constructed with wooden wings, 73 more air launches were performed in December 1948. A ground-launched variant called the 10KhN was tested in 1948, which used rocket-assisted take-off from a ramp; the purpose of the first tests was to determine the feasibility of dropping the 10Kh missile from an aircraft in flight and ignite the pulse jet about 100 m below the mother-ship, but only six out of 22 missiles did so correctly. The second, more successful series of tests, achieved a success rate of 12 out of the 22 launched; the final tests were conducted to determine effectiveness. 10Kh The initial production version of the V-1 reverse engineered look-alike, powered by a single Chelomey D-3, reverse engineered Argus As014 engine.

10Kh Izdeliye 30 An improved version with wooden wings. 10KhN A ground-launched version using rocket assisted take off gear to boost the missile up a launch ramp. 14Kh A further development with revised wings of several configurations and structural material, powered by a single Chelomey D-5 engine. 14KhK1 A sub-version of the Kh14 powered by a single Chelomey D-6. 15Kh A ship launched version. 16Kh Experimental missiles using Kh10 airframes with single Chelomey D-6 engines tested with two Chelomey D-3 engines mounted side by side on V-configured pylons on the aft fuselage and extended tailplanes with rectangular fins and rudders at the tailplane tips. 17Kh A ship launched version. 18Kh A further development of the 10Kh series of cruise missiles. A gliding bomb An un-powered gliding bomb was derived from the 10Kh featuring a twin tail similar to the 16Kh in addition to a central fin, as well as a jettison-able undercarriage
