Most bituminous adhesives or binders that are used for pavement materials are derived primarily from fossil fuels. With petroleum oil reserves becoming depleted and the drive to establish a bio-based economy, there is a push to produce binders from alternative sources, particularly from biorenewable resources. However, until now, no research has studied the applicability of utilizing bio-oils a...

BACKGROUND Diagnosing Plasmodium falciparum malaria during pregnancy is a great challenge for clinicians because of the low density of parasites in the peripheral blood and parasite sequestration in the placenta. Nevertheless, few data on the use of malaria rapid diagnostic test (RDT) during pregnancy have been published. METHODS P. falciparum infections were assessed in 156 febrile pregnant ...

BACKGROUND Avian influenza (AI) is an important zoonotic disease responsible for significant losses in most sub-Saharan countries. However, the role of poultry other than chicken in the epidemiology of the disease, especially after the first AI outbreak in Ghana, has not been fully elucidated. The obiective of this study is to determine whether the AI virus infection that was reported in the ar...

in order to investigation the effects of different combination and amount of chemical, biological and organic manure in present of water absorbent materials on some phenological, morphological and yield of soybean, a field study was carried out gorgan region climate conditions in a factorial experiment based on randomized complete block design with three replications. in this experiment two lev...

Background: DNA immunization with plasmid DNA encoding bacterial, viral, parasitic, and tumor antigens has been reported to trigger protective immunity. The use of plasmid DNA vaccinations against many diseases has produced promising results in animal and human clinical trials; however, safety concerns about the use of DNA vaccines exist, such as the possibility of integration into the host gen...

BACKGROUND Yersiniosis is believed to be the third most common intestinal zoonosis in the European Union, after campylobacteriosis and salmonellosis. Yersinia enterocolitica is the most common species responsible for human infections. Pigs are regarded as the biggest reservoir of pathogenic Y. enterocolitica strains, which are mainly isolated from pig tonsils. The aim of this paper is to examin...

An increase in the antibiotic resistance among Enterococcus faecium strains has been observed worldwide. Moreover, this bacteria has the ability to produce several virulence factors and to form biofilm that plays an important role in human infections. This study was designed to compare the antibiotic resistance and the prevalence of genes encoding surface protein (esp), aggregation substance (a...

there is a great call for using microbial bio-decaffeination approach to remove caffeinefrom caffeinated products and industrial wastes. we aimed in this study to screen strainsof yeasts which exhibit high caffeine tolerance and to investigate the bio-degradation ofcaffeine under growth conditions. sixteen yeast strains were isolated from the cultivatedtea soils collected from sites of northern...

the objective of this research is to investigate the effect of four additives including iron slag (is), works debris (wd), fly ash (fa), and lime kiln dust (lkd) on the biochemical properties of biosolids produced at mangere wastewater treatment plant (mwwtp), auckland, new zealand. all these additives are homogenously mixed in the laboratory with biosolids at various percentages with and witho...
