Bed bugs have made a major comeback in the U.
In the words of this beautiful canticle, Saint Francis of Assisi reminds us that our common home is like a sister with whom we share our life and a beautiful mother who opens her arms to embrace us. This sister now cries out to us because of the harm we have inflicted on her by our irresponsible use and abuse of the goods with which God has endowed her. We have come to see ourselves as her lords and masters, entitled to plunder her at will. The violence present in our hearts, wounded by sin, is also reflected in the symptoms of sickness evident in the soil, in the water, in the air and in all forms of life.
Animal welfare is the well-being of non-human animals. Formal standards of animal welfare vary between contexts, but are debated mostly by animal welfare groups, legislators, and academics. Respect for animal welfare is often based on the belief that nonhuman animals are sentient and that consideration should be given to their well-being or suffering , especially when they are under the care of humans. There are two forms of criticism of the concept of animal welfare, coming from diametrically opposite positions. One view, held by some thinkers in history, holds that humans have no duties of any kind to animals. The other view is based on the animal rights position that animals should not be regarded as property and any use of animals by humans is unacceptable.
Swine flu can affect both pigs and humans. It is a respiratory disease that results from an influenza A virus. The influenza A variant subtype H1N1 is commonly the cause of swine flu in humans. It has similar genetic features to the H1N1 subtype of influenza virus that causes influenza in pigs. Other main subtypes known to occur and cause influenza in pigs include H1N2 and H3N2. There have been infections in humans with these two variant subtypes as well.
Pigeon photography is an aerial photography technique invented in by the German apothecary Julius Neubronner , who also used pigeons to deliver medications. A homing pigeon was fitted with an aluminium breast harness to which a lightweight time-delayed miniature camera could be attached. Neubronner's German patent application was initially rejected, but was granted in December after he produced authenticated photographs taken by his pigeons. He publicized the technique at the Dresden International Photographic Exhibition, and sold some images as postcards at the Frankfurt International Aviation Exhibition and at the and Paris Air Shows. Initially, the military potential of pigeon photography for aerial reconnaissance appeared interesting. Battlefield tests in World War I provided encouraging results, but the ancillary technology of mobile dovecotes for messenger pigeons had the greatest impact. Owing to the rapid perfection of aviation during the war, military interest in pigeon photography faded and Neubronner abandoned his experiments.
Jump to navigation. Carson, a renowned nature author and a former marine biologist with the U. Fish and Wildlife Service, or FWS, was uniquely equipped to create so startling and inflammatory a book. A native of rural Pennsylvania, she had grown up with an enthusiasm for nature matched only by her love of writing and poetry. The educational brochures she wrote for FWS, as well as her published books and magazine articles, were characterized by meticulous research and a poetic evocation of her subject.
There would be a rustle of oily black feathers as a raven settled on the window ledge of a once-grand apartment building in some Eastern European capital. The bird would pace across the ledge a few times but quickly depart. In an apartment on the other side of the window, no one would shift his attention from the briefing papers or the chilled vodka set out on a table. Nor would anything seem amiss in the jagged piece of gray slate resting on the ledge, seemingly jetsam from the roof of an old and unloved building. Those in the apartment might be dismayed to learn, however, that the slate had come not from the roof but from a technical laboratory at CIA headquarters in Langley, Virginia.
This article reviews the use of non-human animals in biomedical research from a historical viewpoint, providing an insight into the most relevant social and moral issues on this topic across time, as well as to how the current paradigm for ethically and publically acceptable use of animals in biomedicine has been achieved. The use of non-human animals in biomedical research has given important contributions to the medical progress achieved in our day, but it has also been a cause of heated public, scientific and philosophical discussion for hundreds of years. This review, with a mainly European outlook, addresses the history of animal use in biomedical research, some of its main protagonists and antagonists, and its effect on society from Antiquity to the present day, while providing a historical context with which to understand how we have arrived at the current paradigm regarding the ethical treatment of animals in research. Animal experimentation has played a central role in biomedical research throughout history. For centuries, however, it has also been an issue of heated public and philosophical discussion.
Это абсолютно исключено. - Спасибо.
Он в последний раз бросил взгляд на труп на алюминиевой столешнице. Покойный лежал на спине, лицом вверх, освещаемый лампами дневного света, вроде бы ничего не скрывая. Беккер непроизвольно снова и снова вглядывался в его странно деформированные руки. Он присмотрелся внимательнее.
Стратмор хмыкнул. Мысль Сьюзан показалась ему достойной внимания. - Неплохо, но есть одно. Он не пользовался своими обычными почтовыми ящиками - ни домашним, ни служебными. Он бывал в Университете Досися и использовал их главный компьютер.
