A 3-year-old Persian queen was referred to Teaching Veterinary Hospital while 3 neonates' umbilical cords were entangled with the queen's tail hair.Close inspection of the cat showed that the umbilical cords of 3 kittens had twisted around together and entangled with the moms' hairs in the base of tail region.Also this complex has been warped around the left tarsus of one of the involved kittens and caused swelling and skin darkness in the involved limb.Operation was carried out urgently.After cutting the queen's involved hairs the kittens were released.Then the twisted umbilical cords and the hairs were isolated from the umbilical cord and the involved leg was released from the umbilical cords and the twisted umbilical cords were separated from each other.During one week follow up,dry gangrene occurred in the distal extremity of the injured limb and consequently,amputation was performed on the distal part of tibia.Our clinical findings suggest that long hair coats of queens could be a maternal life threatening factor for neonates' life. 展开更多

A regional profile of AChE activity was noted in the Indian termite queen Odontotermes redemanni with the head recording the higher and body the lower range of activity. The enzyme characteristics such as substrate and temperature optima were more or less similar while pH requirement for optimum AChE activity varied from 7.0 to 7.6 In vitro inhibition of head and body AChE was studied using pure and commercial anticholinesterase compounds. Interestingly, the commercial formulations like Metacid-50 and Carbaryl are potent enough at 1×10^(-8) M to produce 50% in vitro inhibition of AChE of head and body regions within 15 min of preincubation. A 20 min of preincubation (t0.5) was necessary to record 50% in vitro inhibition of AChE with known and pure anticholinesterase compounds such as DFP (3.5×10^(-10)M) and physostigmine (3.6 ×10^(-10)M). It is surmised that (a) the response of the head and body AChE to the commercial formulations of the insecticides may be used as a reliable and sensitive bioindicator of pesticidal contamination of the terrestrial environment and (b) termite control may be successfully done with the application of organophosphate or carbamate compounds. 展开更多

The queen bee embryo, the chrysalis of the queen bee, is very nutritious and valuable and is also a natural product in the process of manufacturing royal jelly. In modern industrial production, the embryo is produced by transplanting one-day-old worker bee chrysalises into queen bee shaped incubators to allow worker bees to feed them believing they are queen bees. As a result, the weight of these chrysalises increases by some 1,000 times in 70 hours. When the royal jelly is collected, the chrysalises must be 展开更多

In 1970, during the excavations in the area of the Great Temple of Boghazkǒy (the Lower City) a cuneiform tablet was found that at once attracted the attention of Hittitologists. This tablet (Bo 70/10, KBo XXII 2) is the Old Hittite original, written in the old ductus, of KBo III 38 (=2 BoTU 13). The latter, known from the autograph of M.H. Figulla (1918), is a New Hittite copy with a very characteristic ductus and a preference for Akkadian forms where the Old Hittite version uses Hittite words or, more seldom, Sumerograms. The text, known as The Legend about the Queen of Kanis and the City of Zalpa, was published in transliteration and with a commentary by H. Otten (1973). 展开更多

The passing of Queen Elizabeth Ⅱ on September 8,after a reign of over 70 years,brought to the end an extraordinary life,and an era in British and European history.Queen Elizabeth II came to the throne on the death of her father King George VI in February 1952 when Winston Churchill was prime minister.She died only days after appointing the 15th incumbent to this position,Liz Truss.Churchill was born in 1874,and Truss in 1975.There is a gap in the birth years between the first and last prime ministers who served the Queen of 101 years.This is one of many utterly extraordinary statistics about her reign. 展开更多

An US woman soldier and an Iraqi medical student were given a voice to their feelings in Helen Benedict’s Iraqi war Narrative Sand Queen.It was the first time war stories had been told by two women from different nations.Character-narrator Kate Brady,a female American soldier,tells the story about how she tried to be an independent woman respected in American society by the way of being a female soldier,but failed in the end.The thesis focuses on Kate’s narration and analyzes her ethical choices from the perspective of Ethical Literary Criticism.By probing into the ethical situation Kate faces,and exploring the ethical conflicts among rational will and natural will on Kate,this thesis attempts to reveal what led to Kate’s ethical choices and caused her ethical confusion,and more importantly,what made her dreams shatter. 展开更多
