cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
enteritis due to campylobacter is the most common cause of acute bacterial diarrhea worldwide. in most cases, infection occurs as a result of consuming contaminated water or food, especially raw meat of fowls. campylobacters are saccharolytic and fastidious bacteria. these traits limit the number of available biochemical tests by which isolates may be differentiated. these limitations might, in...
INTRODUCTION Live vaccine strain (LVS) Francisella tularensis is a live, attenuated investigational tularemia vaccine that has been used by the US Army for decades to protect laboratory workers. Postvaccination bacterial kinetic characteristics of LVS at the inoculation site and in the blood are unknown and, therefore, were assessed in a prospective study. LVS vaccination of laboratory workers ...
