Wen-jun Hou,Lixing Tanghat is, any method that reduces the population of an abundant pest organism to below an economic threshold will have community-level effects and therefore will inherently pose environmental risks. The scope of this chapter is to review the published evidence for environmental impacts of biological csclera 发表于 2025-3-27 07:06:18
Un Kim,Yaxi Wang,Wenhao Yuanan increased variation of the cellular DNA content in the whole cell population. This effect can be observed in the flow-cytometric DNA distributions as broadening of the G./G.- and G.+M-phase peaks and can be quantitated. Work done along these lines will be briefly reviewed in the following.新字 发表于 2025-3-27 12:01:47
Zhejun Liu,Qin Guo,Zhifeng Jin,Guodong Yual systems, an inter-disciplinary approach is necessary to assess and elucidate the problems that evolve as this field advances and as the use of these energies expands. It is important to maintain a proper perspective and assess realistically the biomedical effects of these radiant energies so thatSpinal-Fusion 发表于 2025-3-27 15:56:44
