흡혈하는 빈대는 총 2종입니다. 빈대(Cimex lectularius, Bed bug)와 반날개빈대(Cimex hemipterus, Tropical bedbug)입니다. 1934년 일제강점기 당시 발행된 조선박물학회잡지 17호에 ‘한국에 2종의 빈대가 조선 각지에 분포한다’고 기록된 바 있지만, 그 이후에도 주로 보고된 것은 빈대종이었습니다. 반날개빈대는 ...
a chilly 5°C. And infections slowly decline as the mercury rises, before stopping altogether at 30°C. Therefore tropical countries, where constantly high temperatures are continued, tend to have relatively even rates of flu infection all year long, without the sharp peaks and valleys of infection rate graphs seen in cooler countries. But cold temperatures aren’t the only reason for the ...
TD: tropical depression)으로 분류하고, 중심부 최대 풍속이 17-32m/초인 경우 열대성폭풍(TS: tropical storm), 중심부 최대 풍속이 32m/초 이상일 때에만 태풍(Typhoon)이라 부른다.열대저기압은 대체로 남·북위 8-15도 지역의 해양에서 발생한다. 해수면의 온도가 27℃ 정도 되는 바다가 열대저기압의 주된 발생지가 ...
Gulf Coast VulnerabilityThere are two main geographic reasons the Gulf Coast is vulnerable.First,our proximity to tropical water pust us in the path of the storms.Second,the water of the Gulf sre warmer than those of the Atlantic,which is attractive to the storms.The entire Gulf region is a magnet for storms looking for a warm place to grow.The Gulf Coast,particularly Louisiana and Mississippi ...
before the malaria genome is completely understood (and funding is running out).Malaria is no longer just another tropical disease. It encompasses the world and must be fought. But as Sheldon M. Schuster, head of the Malaria Genome Project at the University of Florida says, "You need to know the enemy in order to attack it effectively."(c) 1993, Los Angeles Times ...
dominicus, was also found in Dominican amber, and is related to the primitive Mastotermes darwiniensis, which lives in tropical Australia.DNA extraction from the cells of insects trapped in amber is itself an amazing process. Tiny bits of DNA are "amplified" by PCR, the "polymerase chain reaction" technique: in an enzyme solution, the DNA copies itself. The technique, and the study of the DNA, ...
quick death, while the warm water of the tropics is a paradise for swimmers― but not so for sea life in general.The tropical waters, with their dearth of oxygen, are, compared with other parts of the ocean, deserts. The polar waters, however, are rich with life. Microscopic life swarms in incredible abundance. Small animals feed on it, larger animals feed on them, and are eaten by still ...
들 대신에 다양한 인종적 기원을 갖는 토착민들이 살고 있다. 인류가 본래 열대성동물(tropical animal)이었다는 점을 감안한다면 북극지역은 이제 막 탐사가 시작된 남극을 제외하고는 인간이 정착한 마지막 지역임에 틀림없다.북극의 토착민들이 언제부터 북극지방에 살게 되었는지 그 기원은 ...
doing this, we are doing the opposite. The forests of the Earth are being chopped down at a huge rate, espacially in tropical countries such as Brazill. This must be stopped. It is suicidal to maintain that what a country does within its own borders is its own business. The loss of the forests will increase the carbon dioxide supply and decrease the oxygen supply for all humanity. This is an ...
감염사고였다.사건의 발달은 런던에 있는 런던위생열대의학교(London School of Hygiene and Tropical Medicine)에서 시작되었다. 학교건물 4층에 있는 진균실험실에 1973년 1월중 '앤 알지오'라는 아일랜드출신의 여성이 실험실 기사로 취업했다. 그녀는 더블린대학에서 동물학을 전공하고 졸업한지 6개월밖에 ...
