年轻的尼古拉·特斯拉前文 ☛戈斯皮克事件尼古拉·特斯拉的故事摘自玛格丽特·斯通(Margaret Storm)著作RETURN OF THE DOVE:The Story of Freedom's Star(1996)威廉译(这只是一个粗译的版本,小标题为译者所加)5 神秘瞬间1873 年,特斯拉(Nikola Tesla,1856-1943)到格拉茨(Gratz)学习电气工程。他知道命运的力量正在...
The similarity is likely caused by the convergent evolution of two different proteins for DNA binding. The two structures reported here provide insight into the specificity of different σI paralogues in one bacterium. Non-conserved residues in the HTH motif of the SigIC domain specifically bind ...
Although the CAFE results discussed above support selection as a force that drives the loss of (a part of) photosynthesis during the evolution to full mycoheterotrophy of P. guangdongensis, further comparisons with other full mycoheterotrophs are necessary to generalize if the loss of photosynthesis...
In fact, Hippocratic medicine and the search for a healthy human being constitute the “cultural force” that initiates the Greeks´ basic concept of paideia (Jaeger 2013), first establishing a relationship between culture and nature to achieve ideal health. In the book On Human Nature, part ...
First of all, it is important to remember that the Quranic corpus was elaborated in the atmosphere of the civil wars that marked the birth and the first developments of Islam. These wars seem to have played a major role in the elaboration of the official version of the Quran, which the ...
This paper investigates the Yellow Vests movement and the extent it constitutes an original platform for resistance to a sustainability transition agenda i
Force-elongation curves from the tensile tests are shown in Fig. 4a. It is seen that the steel is slightly anisotropic both in flow stress and elongation to failure. This is most evident in the 45° and 90° directions. However, Gruben et al. [25] showed that plastic anisotropy in Docol...
7. Initially, the force-displacement curve ascends almost linearly until F≈75 kN, when the first crack initiates on the inner surface at the middle span. The force increases and reaches the first peak at approximately 110 kN, followed by a very limited drop, as a result of the ...
COVID-19 is a highly spreadable viral infection, reported first in Wuhan, China in December 2019 which spreads worldwide later. The pathogen of this disease is SARS-CoV virus. World Health Organization announced first the name of this new disease and declared this outbreak as a Public Health ...
This allows students to think of evolution not in the common sense—as a unified “force” that punches out “finished” products (e.g., life forms)—but from a new perspective; that evolution is the unintended consequence of three somewhat independent, observable facts of nature. This ...
