According to biodiesel from microalgae is an attractive fuel for several reasons such as renewable, biodegradable and environmental friendly. Thus, this study, green microalgae Scenedesmus acutus PPNK1 isolated from natural water, was selected based on high growth rates, easy cultivation and high lipid content. The Nile red fluorescence method has been successfully applied to the determination ...

BACKGROUND AND OBJECTIVES Previous studies have shown substantial geographical variation in blood donation within developed countries. To understand this issue better, we identified community characteristics associated with blood donor rates in German municipalities in an ecological analysis. MATERIALS AND METHODS We calculated an aggregated rate of voluntary blood donors from each of 1533 mu...

OVERVIEW The plasma supply for pharmaceutical manufacturing consists of surplus plasma recovered from whole blood collection and source plasma from plasmapheresis in Korea. Shortages are typically covered by importation. The total plasma supply for fractionation was 608,352 liters in 2009, of which 430,267 liters were supplied domestically. The self-sufficiency rate was, therefore, about 71% in...

A comprehensive seroepidemiologic study was conducted in two Red Cross regions (Los Angeles and Miami) to determine the prevalence of Trypanosoma cruzi antibodies in at-risk blood donors, to identify additional risk factors, and to assess the likelihood of transmitting T. cruzi by transfusion. At-risk and control donors were stratified by a broad risk question, tested for T. cruzi antibodies, a...

As communities across the United States attempt to address red light running (RLR), a number of them have implemented RLR camera-enforcement programs. Since 2004, three Iowa communities—Davenport, Council Bluffs, and Clive—have implemented RLR camera-enforcement programs. The objective of this research was to evaluate the effectiveness of RLR cameras in these three Iowa communities. A reduction...

Well-distributed eolian red clay in a wide area of northern China is believed to imply the onset of an ancient East Asian monsoon system since Late Miocene. Two continuous red clay sequences spanning the time interval 7-2.6 Ma and 11-2.6 Ma in the Chinese Loess Plateau was investigated to determine the magnetic orientation and grain alignment in the primary fabric of eolian sediments. The north...
