Two strains of Ixodes spirochetes, one isolated in the United States (B31) and the other in Sweden (G25), were examined by electron microscopy. Cells of strain G25 were 11-25 micron long with a wavelength of 2.1-2.4 micron and an amplitude of 0.4 micron. Eleven flagella were inserted subterminally at each end of the cell. Cells of strain B31 were similar but had eleven or seven flagella. Cytopl...

Isolated bovine retinal and brain microvessels, exhibiting a patent lumen, were used to study the contribution of the microvasculature to the blood-brain and blood-retina barriers. The diffusion marker, sucrose, was taken up slowly by the isolated microvessels in contrast to leucine, tyrosine, and valine which were taken up at a considerably faster rate. Uptake of leucine was temperature depend...

A new class of fires suppressants, known as Encapsulated Micron Aerosol Agents (EMAA), having superior volumetric efficiency, low initial and life cycle costs, low toxicity, no known global atmospheric environmental impacts (ODP/GWP), and with the potential for a wide variety of applications, is being developed via a joint program between the private sector and the U.S. Air Force. The research ...

We present new room-temperature 1100 - 1800 cm^{-1} spectra of melilite silicates and 600 2000 three randomly orientated fine-grained carbonates to determine the possible carrier(s) a 6.9~micron absorption feature observed in variety dense astronomical environments including young stellar objects molecular clouds. focus on low-mass post-AGB star Sakurai's Object which has been forming substanti...

Micron-CT technology can make up for many shortcomings of traditional rock physics experiments and provide a new platform research. In this paper, 3D digital core model with realistic pore structure characteristics was established using micron-CT scanning combined advanced image processing techniques carbonate rocks as the research object. Various morphological algorithms included in software (...
