A more comprehensive understanding of how ocean temperatures influence coc co lithophorid production of particulate inorganic carbon (PIC) will make it easier to constrain the effect of ocean acidification in the future. We studied the effect of temperature on Emiliania huxleyi PIC production in the Barents Sea using ocean colour remote sensing data. Gross annual PIC production was calculated f...

The Earth’s core is made up of a solid inner portion, encircled by a liquid metallic region [Fig. 1]. Surrounding this is a thick mantle made up of silicates and minor amounts of metal (perhaps reaching 1 wt%), and the outermost layer is the crust, made up of silicates (Figure 1). The mantle is not homogeneous – there are distinct regions of differing mineralogy and composition [2]. Understandi...

1.1 Current situation in the development of pharmaceuticals A typical testing scheme for a small-molecule therapeutics (outlined in Fig. 1) begins with a large number of compounds and high-throughput assays (Kramer et al., 2007). As the number of viable lead molecules is reduced, incrementally more predictive but lower throughput assays identify those leads with the most drug-like properties an...

Garcinia kola tree, known as "bitter kola," to treat infectious diseases. This treatment has no apparent side effects. In vitro tests of the plant identified 46 biochemical principles that appear to kill bacteria and viruses, including the deadly Ebola virus, the cause of fatal hemorrhagic fever. "The same forest that yields the dreaded Ebola virus could be a source of the cure," said Maurice I...

BACKGROUND Psycho-active substance use among adolescents is a national and global problem and its attendant effects on adolescents cannot be overemphasized. The objectives of this study are to determine the prevalence and pattern of psychoactive substance use among adolescents; the substances involved and the extent of the problem in this locale. METHODS This is a cross-sectional study that a...

Gotu kola is often used to make fresh juice without heating. In Nha Trang, gotu kola drinks are usually prepared and refrigerated while being traded. Listeria monocytogenes a bacterium capable of growing at cold temperatures; whereas the pathogenicity low, mortality rate can be up 25 - 30%. Therefore, assessment level L. monocytogenes contamination on raw in ...
