King penguin

The king penguin is the second largest species of penguin, but somewhat similar in appearance to the emperor penguin. There are two subspecies: A. p. halli. King penguins eat lanternfish and krill. On foraging trips king penguins dive to over 100 metres, have been recorded at depths greater than 300 metres. King penguins breed on the subantarctic islands at the northern reaches of Antarctica, South Georgia, other temperate islands of the region; the king penguin weighs from 9.3 to 18 kg. Although female and male king penguins are monomorphic they can be separated by their calls. Males are slightly larger than females; the mean body mass of adults from Marion Island was 11.1 kg for 71 females. Another study from Marion Island found; the king penguin is 25% shorter and weighs around 1/3rd less than the emperor penguin. At first glance, the king penguin appears similar to the larger related emperor penguin, with a broad cheek patch contrasting with surrounding dark feathers and yellow-orange plumage at the top of the chest.

However, the cheek patch of the adult king penguin is a solid bright orange whereas that of the emperor penguin is yellow and white, the upper chest tends to be more orange and less yellowish in the king species. Both have colourful markings along the side of their lower mandible, but these tend towards pink in emperor penguin and orange in king penguin. Emperor and king penguins do not inhabit the same areas in the wild, with the possible exception of vagrants at sea, but the two can be distinguished from one another by the king's longer, straighter bill and noticeably sleeker body; the chicks of both species are different from one another in appearance. Once molted of its heavy dark brown down, the juvenile king penguin resembles the adult but is somewhat less colourful. King penguins breed on the same large, circumpolar islands as at least half of all living penguins, but it is distinguished from co-occurring penguins by its much larger size and taller frame, distinctive markings and grizzled sooty-greyish rather than blackish back.

King penguins breed on subantarctic islands between 45 and 55°S, at the northern reaches of Antarctica, as well as Tierra del Fuego, the Falkland Islands, other temperate islands of the region. The total population is increasing; the largest breeding populations are on the Crozet Islands, with around 455,000 pairs, 228,000 pairs on the Prince Edward Islands, 240,000–280,000 on the Kerguelen Islands and over 100,000 in the South Georgia archipelago. The King penguin population on South Georgia and the Falklands was nearly wiped out by the early 1920s by whalers on the islands who would eat the birds and their eggs, burn the oily, blubber rich penguins as fuel. Macquarie Island has around 70,000 pairs; the non-breeding range is unknown due to many vagrant birds having been seen on the Antarctic peninsula as well as in South Africa and New Zealand. King penguins appear to have suffered a massive population decline of nearly 90% on Île aux Cochons, or Pig Island in the Crozet Archipelago. Analysing new helicopter and satellite images from 2015 and 2017, the colony's numbers have dropped to 60,000 breeding pairs.

The cause of this decline may be due to changes in the ecosystem related to climate change as their primary source of food is moving farther away from places where the penguins can breed. This may result in population declines and shifts in the locations of the King penguin breeding grounds; the Nature Protection Society released several king penguins in Gjesvær in Finnmark, Røst in Lofoten in northern Norway in August 1936. Penguins were seen in the area several times during the 1940s. American zoologist Gerry Kooyman revolutionized the study of penguin foraging behaviour in 1971 when he published his results from attaching automatic dive-recording devices to emperor penguins, recording a dive of 235 metres by a king penguin in 1982; the current maximum dive recorded is 343 metres in the Falkland Islands region, a maximum time submerged of 552 seconds recorded at the Crozet Islands. The king penguin dives to depths of 100–300 meters, spending around five minutes submerged, during daylight hours, less than 30 metres at night.

The majority of dives undertaken by king penguins are flat-bottomed. They have been described relating to the course of the dive; the remaining 12% of dives have a V-shaped or "spike" pattern, in which the bird dives at an angle through the water column, reaches a certain depth, returns to the surface. In contrast, other penguins dive in this latter foraging pattern. Observations at Crozet Islands revealed. Using the average swimming speed, Kooyman estimated the distance travelled to foraging areas at 28 km; the king penguin's average swimming speed is 6.5–10 km/h. On shallower dives under 60 m, it aver

Field kitchen

A field kitchen is a mobile kitchen, mobile canteens or food truck used by military services to provide warm food to the troops near the frontline or in temporary encampments. The first field kitchens were carried in four-wheeled wagons by military units on campaign throughout history. Indeed, this method of feeding a large travelling group of people was used, such as on the Wagon Trail in late 19th Century America where the Chuckwagon was employed. By the 20th Century, smaller two-wheeled trailers, became common with the invention of locomotive travel. Field Kitchens were given affectionate nicknames. Karl Rudolf Fissler of Idar-Oberstein invented a mobile field kitchen in 1892 that the Germans came to refer to as a Gulaschkanone because the chimney of the stove resembled ordnance pieces when disassembled and limbered for towing; as technology has advanced, larger trailers have evolved as horses were phased out in favour of motorized vehicles more capable of towing heavier loads. In WWII the mobile canteen was used as a morale booster in the United Kingdom, fitting in with the culture of the tea break and in particular as a result of the successful wartime experiment of the tea lady on productivity and morale.

The larger mobile kitchens can service entire battalions of troops. Canteen Field ration Mess Mess kit Chuckwagon Yagai suigu

Muthoni Kirima

Muthoni wa Kirima is a retired top-ranking female fighter in the Kenya Land and Freedom Army of the Mau Mau Uprising in the 1950s. Few Mau Mau women became active fighters, Muthoni is the only woman to have attained the Mau Mau rank of field-marshal. Muthoni wa Kirima was born in 1931 to parents working on a European farm in Kenya's central region, her journey as a revolutionary started when she was a girl, saving money to fund Jomo Kenyatta's travels abroad. After her marriage to General Mutungi, she moved to a village reserve for Africans in Nyeri before joining the Mau Mau. In her 20s, she worked as a spy for Mau Mau fighters who had camped in the forest when war broke out in 1952. During the war, Muthoni was wounded on two occasions. On one and seven other fighters were attacked, she was able to crawl to safety with a gunshot wound in her shoulder, but all the others were killed. Muthoni was never caught in the forest, she moved out of the forest after Kenya gained independence from Britain in 1963.

Her husband, General Mutungi, died two years later. Field Marshal Muthoni got a license to trade in ivory in 1966, recovering and selling tusks the Mau Maus had buried around Mount Kenya, having hunted elephants for food and ivory during the uprising, her permission to collect and sell "wild" ivory ended in 1976. In 1990, she served as a nominated councilor in central Kenya. In 1998, President Daniel arap Moi awarded her a medal for distinguished service, in 2014, President Uhuru Kenyatta awarded her the Head of State Commendation. Muthoni wa Kirima lives in a Nyeri suburb. "Kenya is my only child," she told the Daily Nation in an interview in 2012, referencing a miscarriage during her time in the forest which left her unable to conceive. As of 2013, she still has the long dreads, she has said that she will not cut her hair until she sees the benefit of independence

Natural frequency

Natural frequency known as eigenfrequency, is the frequency at which a system tends to oscillate in the absence of any driving or damping force. The motion pattern of a system oscillating at its natural frequency is called the normal mode. If the oscillating system is driven by an external force at the frequency at which the amplitude of its motion is greatest, this frequency is called resonant frequency. Free vibrations of an elastic body are called natural vibrations and occur at a frequency called the natural frequency. Natural vibrations are different from forced vibrations which happen at the frequency of an applied force. If the forced frequency is equal to the natural frequency, the vibrations' amplitude increases manyfold; this phenomenon is known as resonance. In a mass-spring system, with mass m and spring stiffness k, the natural frequency can be calculated as: ω 0 = k m In electrical circuits, s1 is a natural frequency of variable x if the zero-input response of x includes the term K 1 e − s 1 t, where K 1 ≠ 0 is a constant dependent on initial state of the circuit, network topology, element values.

In a network, sk is a natural frequency of the network if it is a natural frequency of some voltage or current in the network. Natural frequencies depend only on network element values but not the input, it can be shown that the set of natural frequencies in a network can be obtained by calculating the poles of all impedance and admittance functions of the network. All poles of the network transfer function are natural frequencies of the corresponding response variable; these frequencies happen at some special initial states. In LC and RLC circuits, the natural frequency of a circuit can be calculated as: ω 0 = 1 L C Fundamental frequency Bhatt, P. Maximum Marks Maximum Knowledge in Physics. Allied Publishers.
