In situ transmission electron microscopy (TEM) is used to study the electrochemical lithiation of high-capacity crystalline Si nanoparticles for use in Li-ion battery anodes. The lithiation reaction slows down as it progresses into the particle interior, and analysis suggests that this behavior is due not to diffusion limitation but instead to the influence of mechanical stress on the driving f...

BACKGROUND The discontinuation of mechanical ventilation after coronary surgery may prolong and significantly increase the load on intensive care unit personnel. We hypothesized that automated mode using INTELLiVENT-ASV can decrease duration of postoperative mechanical ventilation, reduce workload on medical staff, and provide safe ventilation after off-pump coronary artery bypass grafting (OPC...

in this study, damar batu (db) − a novel biomaterial− is evaluated for its potential application in pharmaceutical coating. db is a whitish to yellowish resin, characterized initially in terms of solubility, acid value, molecular weight (mw), polydispersity index (mw/mn) and glass transition temperature (tg). neat plasticized films of db are investigated for mechanical, water vapor transmission...

Anaplasma marginale Theiler is a tick-borne intraerythrocytic rickettsial pathogen of cattle that also can be mechanically transmitted by biting flies. Rickettsemia during the acute phase of infection may reach as high as 10(9) infected erythrocytes (IEs) per milliliter of blood. Animals that survive acute infection develop a life-long persistent infection that cycles between 10(2.5) and 10(7) ...

Mechanical transmission ofAnaplasma marginale by horse flies (Tabanidae) is thought to be epidemiologically significant in some areas of the United States. We compared the relative efficiencies of mechanical transmission of Anaplasma marginale by the horse fly, Tabanus fuscicostatus Hine, during acute infection (approximately 10(7) to approximately 10(9) infected erythrocytes [IE]/ml blood) wit...
