Desert rat-kangaroo

The desert rat-kangaroo called the buff-nosed rat-kangaroo, plains rat-kangaroo or oolacunta, is an extinct small hopping marsupial endemic to desert regions of Central Australia. It was discovered in the early 1840s and described by John Gould in London in 1843, on the basis of three specimens sent to him by George Grey, the governor of South Australia at the time, it was formed like a kangaroo, but had the bulk of a small rabbit, was described as having a delicate and slender form. The length of the head and body combined is estimated to be about 254–282 mm in addition to a 307 to 377 mm long tail, its head was short and wide, different from that of any kangaroo or wallaby with a naked nose and rounded ears. The color of its dense, soft fur was appropriate for its desert surroundings, it was pale yellowish brown, the hairs tipped with sooty brown. Its underbelly was described as white with pale yellowish-brown feet and tail. A distinguishing feature of this species was the difference in size between hind limbs.

Its fore limbs were quite delicate with bones weighing 1 gram, while its hind limbs are large with bones weighing 12 grams. This difference is related to saltation. Other characteristics related to hopping locomotion include a rather thin tail. Caloprymnus campestris was thought to occupy a small area in South Australia, extending just over the borders of southwestern Queensland and Northern Territory, it was last seen in 1935 in the eastern Lake Eyre basin of northern Southern Australia The desert rat-kangaroo lived in the desert regions of Australia, including clay pans, loamy flats, sand ridges, gibber plain habitats. Its native habitat was arid, cover is sparse, consists of saltbush and other chenopods and emu bush. Caloprymnus campestris was solitary except for mothers with young offspring, it lived in nests built over shallow depressions in the ground. These nests were excavated or found and are crucial in the desert, where temperatures can be high, while little brush or foliage is available for cover.

The "pits" were lined with grass. The nest would be covered with twigs to provide cover from the scorching sun; the desert rat kangaroo was found peeking out of the top of the nest to observe its surroundings. This species would spend most of the day taking cover in the nest, emerge at dusk to feed. Thus, it was at least nocturnal; the desert rat-kangaroo was herbivorous, feeding on foliage and stems of desert vegetation, but has been found to eat insects such as beetles and weevils. It was so independent of water, it shunned the succulent plants of the sand hills, it was able to survive without any surface water. It had a distinct method of hopping, its posture was forward and the long tail was extended when it moved at high speeds. Unlike other marsupials, Caloprymnus would land with the right foot in front of the left foot, it showed great endurance while being chased on horseback at high speeds, "paused only to die". Females reached sexual maturity at about 11 months, while males reached maturity some two months later.

Marked sexual dimorphism was apparent, with females being larger. Females could mate throughout the year. Although able to mate all year, they had an irregular breeding season. Females with pouched joeys had been found between December. Young were born undeveloped, as is typical of marsupials. Gestation was around one to two months, with a pouch period of two to three months. All females were found with only one young at a time. Young remained dependent for over a month after leaving the pouch and soon after would leave permanently; the desert rat-kangaroo was discovered in the early 1840s. However, after these early sightings, it was no longer recorded for 90 years, was believed to be extinct; this species before European colonisation, was never abundant. Following the relief of drought conditions which improved the local habitat, the animal was rediscovered in 1931 when Hedley Finlayson found a thriving colony of them, he made multiple returns. The last confirmed record of the species came in 1935 from near Ooroowilanie, east of Lake Eyre.

Caloprymnus campestris was well adapted to the barren and arid regions it inhabited. However, as early as the 1930s, the red fox had spread to the areas inhabited by the desert rat kangaroo. Thus, the rapid decline of the desert rat-kangaroo began shortly after its recovery in 1931 correlates with the invasion of its habitat by the fox. Predation by the red fox and cats, as well as variable seasonal patterns and overhunting by indigenous Australians, were blamed for the extinction of this species. No reliable reports of the species have been made since 1935, but unconfirmed sightings in Queensland followed periods of rain in 1956-1957 and 1974-1975. Recent remains of this species have been found in the mid 1980s inside caves; the desert rat-kangaroo was declared extinct in 1994, making it the only mammal species to be recovered and lost again. In view of its amazing recovery following a 90-year period when it was not seen, the extinction of the desert rat-kangaroo is not certain. In similar cases, the broad-faced potoroo was last seen in the late

UpFront Records

UpFront Records is a record label owned and founded by DeVyne Stephens. Stephens began his career in the early 1990s with Devyne featuring 90 Miles an Hour. "I was one of the first artists L. A. and Babyface signed to LaFace Records," he says. But the group broke up. Undaunted, Stephens found his niche as a imaging expert for LaFace Records, he worked with everyone from Toni Braxton and Pink to TLC, Usher and Boyz II Men. He says. "Being I'm a native from Atlanta, I cultivate that style and put it on different artists," he says. Stephens discovered Senegalese R&B singer Akon, he secured a distribution deal with SRC/Universal. "I always believed that Akon was special," he says. Akon went on to sell over a million copies of his 2004 debut and score hit singles like "Locked Up" and "Lonely." UpFront Records' roster includes Akon, R&B quartet Red Dirt, rap group FA. He says there isn't much difference between his former job at LaFace and his current duties as a record executive, he teaches his artists, "The first thing people look.

Potassium persulfate

Not to be confused with potassium peroxymonosulfate. Potassium persulfate is the inorganic compound with the formula K2S2O8. Known as potassium peroxydisulfate or KPS, it is a white solid, sparingly soluble in cold water, but dissolves better in warm water; this salt is a powerful oxidant used to initiate polymerizations. Potassium persulfate can be prepared by electrolysis of a cold solution potassium bisulfate in sulfuric acid at a high current density. 2 KHSO4 → K2S2O8 + H2It can be prepared by adding potassium bisulfate to a solution of the more soluble salt ammonium peroxydisulfate 2S2O8. In principle it can be prepared by chemical oxidation of potassium sulfate using fluorine; this salt is used to initiate polymerization of various alkenes leading to commercially important polymers such as styrene-butadiene rubber and polytetrafluoroethylene and related materials. In solution, the dianion dissociates to give radicals: 2− ⇌ 2 •−It is used in organic chemistry as an oxidizing agent, for instance in the Elbs persulfate oxidation of phenols and the Boyland–Sims oxidation of anilines.

As a strong yet stable bleaching agent it finds use in various hair bleaches and lighteners. Such brief and non-continuous use is hazard free, however prolonged contact can cause skin irritation, it has been used as an improving agent for flour with the E number E922, although it is no longer approved for this use within the EU. The salt is incompatible with organic compounds. Prolonged skin contact can result in irritation

Alexander Murylev

Alexander Vladimirovich Murylev, known as the "Yeltsin's Sanitary", is a Russian serial killer and former real estate broker, between 1993 and 1994, killed several alcoholics in order to appropriate and sell their apartments. Alexander Murylev was born in 1971 in the family of an officer of the Soviet Army. Before coming of age, he lived with his family in East Germany, where his father held a high position in the counterintelligence headquarters of the Group of Soviet Forces. Returning to the USSR, Murylev enrolled into a medical school. After graduating from it, he went to the army. After demobilization, Murylev tried to enroll in the MSU Faculty of Journalism, but was unsuccessful. After that, he got a job as a freelance correspondent in a number of Moscow print media. One time he was given a task by the editorial which led him one of the metropolitan casinos, where the young man got addicted to gambling, he began to spend all his free time in gambling houses, once he lost a large sum of money.

Due to this, he began to commit crimes. Murylev was well versed in the issues of privatization and housing sales, to which his journalistic work contributed a lot. So, in one of the newspapers, shortly before this, an article published by Murylev titled "Small privatization - a great swimming" was followed up by "And what about the big one?", which raised the issue of privatization of real estate in Moscow. Murylev knew that he law was passed in hurry, for the sale of someone's apartment only one document was enough - a power of attorney could dispose of it. Murylev investigated the places where marginal personalities gathered, in particular, single alcoholics, he treated his victims to alcohol, having made sure they had no close relatives, he offered to sell or exchange with the surcharge of their apartment. Having heard the sums, huge for them, they made out powers of attorney on Murylev. After that, Murylev killed them, he always checked the pulse of his victims. He committed his first murder in July 1993.

Murylev disposed of the body in the Moskva River, where it was found on July 30. The body could not be identified and was cremated, but a year Zheleztsov's brother identified the corpse from his wristwatch, preserved by the authorities. In the same month, Murylev committed two more murders - those of a man named Troshin and his mistress Vinokurova; the double murder was committed at Troshin's apartment, with Murylev wrapping up the bodies in a blanket, calling a taxi, going to another area and subsequently disposing of the corpses by throwing them down a manhole. The bodies were discovered a year only thanks to Murylev's testimonies; the following murder, that of a man named Sidorov, was done in Murylev's own apartment, where he killed the man with a cleaver. In September 1993, Murylev tried to persuade a certain Alexander Ershov to issue a power of attorney for him to sell the apartment. Ershov refused, appealed to the police. A week he was killed by Murylev, who took him out of town and shot him with a TT pistol.

Soon after, Murylev killed a daughter named Petukhovi, who suffered from alcoholism. Their bodies were thrown into the manhole; the next day, Murylev brought to the same place a man named Bulanenkov, in a state of intoxication, putting him on the edge of the manhole and waited until the man fell down and drowned. In the spring of 1994, Murylev began to engage in apartment sales, for which he used the services of official real estate companies. During the inspection of one of these apartments, an agent of one company was arrested, who mentioned Murylev. Two days Murylev was detained at the Belorussky railway station in Moscow. Murylev soon confessed to the murders of 8 people, describing in detail his crimes to the investigators. At one of the interrogations, he told the investigator that he was "Yeltsin's Sanitary", helping clear Russia from marginal elements; some of the bodies were found. In 1996, the Moscow City Court sentenced to Alexander Murylev to death, but the sentence was commuted to life imprisonment in a special regime colony according to a moratorium on the death penalty.

Murylev is serving his sentence in the White Swan prison. His accomplice, the notary Igor Agarkov, who pledged the false powers of attorney, was sentenced to six years imprisonment. Subsequently, Murylev assured journalists that he is innocent and is a victim of a judicial error
