Yuan, Guodong - - 2009
Soil plots on a pasture were amended with biosolids spiked with copper (Cu), nickel (Ni), or zinc (Zn), resulting in maximum concentrations of 181 mg Cu, 58 mg Ni, and 296 mg Zn/kg in soil. Soil solutions from the plots were obtained by centrifugation for chemical analyses, and free metal ...

An incubation experiment was carried out to assess the rate of oxidation of lead (Pb) shot and subsequent transfer of Pb to the soil under different soil moisture and temperature regimes. Lead was readily released from Pb shot into the soil environment due to rapid corrosion of the Pb shot; ...

The adsorption characteristics of tetracycline by 2 soils including a clay-rich soil (cinnamon soil) and an iron oxide-rich soil (red soil) were investigated as a function of soil organic matter (SOM). SOM is the main adsorbent for tetracycline in the soil environment. The results indicated that the adsorption kinetics of ...

Australian agriculture contributes an estimated 16% of all national greenhouse gas emissions, and considerable attention is now focused on management approaches that reduce net emissions. One area of potential is the modification of cropping practices to increase soil carbon storage.

Cropland may play a significant role in mitigating climate change by sequestering atmospheric C[O.sub.2]. To evaluate the extent of carbon sequestration, an examination of the changes in soil organic carbon (SOC) is essential. We compiled data from 50 published papers that reported changes in the SOC in eastern China over ...
Machado, P.L.O.A. - - 2009
The objective of this study was to determine, at a farm level, the spatial variability of organic carbon stock (CS) at different depths on a field of 1 soil type in long-term (13-year) crop production under no-tillage. The crop rotation comprised soybean [Glycine max (L.) Merr.] alternating with maize (Zea ...
Hulugalle, N.R. - - 2009
The well-documented decline in soil organic carbon (SOC) stocks in Australian cotton (Gossypium hirsutum L.) growing Vertosols has been primarily analysed in terms of inputs from above-ground crop residues, with addition to soil C by root materials being little studied. Potential contribution by cotton roots to soil carbon stocks was ...

Since April 2006, in accordance with its mandate to provide guidance to member states World Health Organization (WHO) issues a series off regularly updated position papers on vaccines and vaccine combinations against diseases that have an international public health impact according to the experts report. WHO published its first position ...

Gastroenteritis is the leading cause of morbidity and mortality in children worldwide. The most common cause is Rotavirus, although it varies by age and region. Rotavirus is responsible for severe diarrhea. The severity of disease is related to dehydration, electrolyte disturbance and metabolic acidosis. Thus clinical evaluation begins with the ...

Invasive fungal infections are important cause of morbidity and mortality especially in immunocompromised children. In response to the increased incidence and high mortality, novel antifungal agents have been developed. In this review, the efficacy of antifungal drugs and the change of the antifungal therapy were evaluated.
Soysal, Ahmet - - 2009
Invasive fungal infections (IFIs) have historically been associated with high morbidity and mortality. Although Candida species have been the most common cause of IFI, recently there has been an increase in the incidence of infections produced by non-candidal yeasts. Infections by Candida species, especially candidemia, are currently one of the ...

The molds are ubiquitous in nature. They have a wider impact on humans as plant pathogens causing fruit decay than as human and animal pathogens. The mold spores are frequently isolated from the air because spores are light weighted, resistant to desiccation and easily dispersed. The Aspergillus can be recovered ...

Osteomyelitis and septic arthritis, before the discovery of penicillin, were associated with a high mortality; at present, however, the disability related to these infections is an important health problem. Early diagnosis followed by appropriate treatment is the best method for preventing or reducing disability related to osteomyelitis and septic arthritis. ...
Kurugol, Zafer - - 2009
Rotavirus is a major cause of severe gastroenteritis in children aged <5 years worldwide. Rotavirus causes an estimated 600.000 deaths and more than 2 million hospitalizations each year. In addition to causing morbidity and mortality in children, rotavirus gastroenteritis creates a major economic burden on health care systems and families. ...
