V. RELATIONSHIP OF ANIMAL VIRUS STRUCTURES TO THEIR IMMUNOLOGICAL PROPERTIES AS DETERMINED BY ELECTRON MICROSCOPY

Electron Microscopy of Fowl Pox Virus

Examination of Lung Parenchyma by Electron Microscopy

In this paper many of the principal struc­ture of the Moral Lung were studied with the help of Electron Microscopy. Detailed descrip­tion was given of Granular Pneumocytes, Membranous Pneumocytes, Macrophages, and Alveolar Capillaries. A discussion followed on the form and function of Granular Pneumo­cytes.  Acknowledgements  I am grateful to the Reza Shah Pahlavi Foundation for its generou...

Properties of the Ehrlich ascites tumor cell as determined by electron microscopy, ultracentrifugation, and hydrostatic pressure.

In fact, it was not until the development of the air-turbine ultracentrifuge (5) that an instrument capable of producing stratification in normal somatic and neoplastic cells became available. Guyer and Claus (12†" 14) were the first to study the phys ical nature of neoplastic cells by use of the air-turbine ultra centrifuge. They observed a difference between the displace ability of the cont...

Four-stranded Dna as Determined by Electron Microscopy

Pneumococcus DNA, of weight-average molecular weight 1.6 million by light scattering, had a weight-average length of 4300 A by electron microscopy. Thus, the average mass per unit length was 370 molecular-weight units per A, or approximately two times that expected (208) for a Watson-Crick double helix. This corresponds to an average of 3.6 strands per molecule, which is close to that obtained ...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
