Using such specimens, the researchers sequenced a sandwort specimen (Arenaria globiflora) collected nearly 200 years ago in Nepal and, despite the poor quality of its DNA, were able to place it in the tree of life. They even analyzed extinct plants, such as the Guadalupe Island olive (Hesper...
The above account of the economic life of a Chinese village is the result of a microscopic examination of a specimen. 上述一个中国村庄的经济生活状况是对一个样本进行微观分析的结果。 tr.hjenglish.com 8. His former life of freedom and happiness is all but buried as the new social order makes...
seem to yield to the habit of finding happiness in doing things, in love and in the memory of love. I hope I never lose that habit either. It would be like putting out the light. So I learned to live, by the great laws, and these little rules of thumb. I wouldn’t take a mill...
The latter results in a cavalry charge that stops short of contact with all figures firing their pistols at the enemy. As I have been DEEP into convention prep this month, I am just going to be brief here and show you some WIP and the finished products. For these, I chose a lot of...
The laser clad specimens showed a reduced fatigue life compared to the specimen without cladding but of the same size due to the presence of residual stresses in substrate and coating regions. The presence of higher compressive residual stresses in substrate region and lower tensile residual stress ...
The fatigue life of a poled PZT specimen under mechanical cyclic loading conditions in four-point bending is predicted by the finite element method, using a continuum damage mechanics approach. The damage parameter is defined as a scalar in proportion to the microcrack density in a representative ...
The only plants with that kind of calyx are this group of 80 or 90 species," said Stacey Smith, an author of the paper.The well-preserved specimen(标本) was revealed in the Green River Formation, a site chock-full of Eocene(始新世的) fossils and discoveries. But, it ended up not ...
section of roundworm. The combination of the fluorescence lifetime-based information and the fluorescence intensity with a stage application, gives an extra layer of contrast to tell different structures apart. LAS X Navigator enables this task to be performed seamlessly over the entire specimen. ...
A microscopy technique that transmits a beam of electrons through an ultra-thin specimen and that is capable of imaging at much higher resolution than light microscopy. Field emission scanning electron microscopy An electron microscopy technique in which an image is produced by scanning the sample wi...
which considered the size effect.The maximum stress and stress ratio have been taken into the life reliability computation of the disk as parameters.Then the fatigue life reliability of a disk simulation specimen was analyzed by the method given.The difference between computational median life in ...
