which was highly developed at that time. The TEM uses an accelerated and focused high-voltage beam to illuminate the object and create an image in the manner of an optical microscope using light. The electron beam is created by a hot, biased cathode...
Their designs cater to their respective purposes: telescopes often have larger apertures to collect more light from distant stars, while microscopes focus on illuminating and enlarging minuscule subjects. 5 One primary distinction between a telescope and a microscope lies in the nature of the observed...
Immunogold electron microscopy (IEM) was completed to visualize cellular expression of the hydrolytic enzyme cathepsin L2 (Cath L2) and biochemical assay was performed to ascertain Cath L2 activity. Immunoblotting of light and dark epidermal lysates demonstrated that of the six enzymes initially ...
A marked sexual difference in kininase activity was found in the adult mouse submandibular gland. The activity was over 3-fold higher in females than in males between 10 and 12 weeks of age. Castration of male mice increased kininase activity up to the level of females. Testosterone administra...
Developments in spectrometers are making new spectroscopies possible and with the push for more light-driven technologies, these tools and methodologies will only become ever more important. To summarize, spectroscopy is the study of the interaction between light and matter, whereas spectrometry refers ...
PRL and GH cells in the adenohypophysis of adult mice were studied with immunohistochemistry and stereological morphometry by light and electron microscopy. We compared findings for males and females. In female mice, most PRL-immunoreactive cells (43% of all parenchymal cells) and most GH-immunoreac...
The supersonic expansion of a heavy gas and a light gas may result in a velocity slip and a temperature difference between light and heavy species. The pur... K Takamura,Y Sakiyama,Y Matsumoto - 《Proceedings of Thermal Engineering Conference》 被引量: 0发表: 2001年 Translational nonequilibri...
aAbstract: A known species,Physarum melleum,was found fruiting on living leaves of Dendrobium candidum,which was collected in China in 2004.Its morphological characters were revealed by light microscopy(LM),environmental scanning electron microscopy(ESEM)and scanning electron microscopy(SEM).Character ...
The air gap between the hotter part and cooler part is 1 cm. Measurement and characterization Morphology of the samples are characterized by emission scanning electron microscopy Apreo S. The output current signals of TDNG are measured by a low-noise current preamplifier Stanford Research SR570...
Three ulnar nerves at the elbow were obtained at necropsy on two patients with unrelated terminal illnesses and were examined by light and electron microscopy. In one case clinical evidence of ulnar neuropathy had been present. A neuroma... D Neary,RA Eames - 《Neuropathology & Applied Neurobiolo...
