Different pathways towards the generation and detection of a single metal nanoparticle (MNP) on a conductive carbon support for testing as an electrocatalyst are described. Various approaches were investigated including interparticle distance enhancement, electrochemical and mechanical tip-substrate MNP transfer onto macroscopic surfaces, scanning electrochemical microscopy (SECM)-controlled el...

Forest land-use changes have long been suggested to profoundly affect soil microbial communities. However, how forest type conversion influences soil microbial properties remains unclear in Tibetan boreal forests. The aim of this study was to explore variations of soil microbial profiles in the surface organic layer and subsurface mineral soil among three contrasting forests (natural coniferous...

Cerebral fat embolism (CFE) is a rare, albeit serious complication of long-bone fractures. CFE results in variable neurological disability, often associated with a significant recovery time. Magnetic resonance imaging (MRI), particulary diffusion-weighted imaging (DWI), is the most sensitive method to establish a diagnosis of CFE, with typical findings of multiple punctate highintensity lesions...

Soil microbes are involved in many important ecosystem processes including nutrient acquisition, biogeochemical cycling and soil aggregation. microbial diversity affects the belowground dynamics fate of carbon nutrients. for agricultural plant production systems, hence understanding effects agroforestry systems on microbes, is necessary order to improve health fertility. The objective study was...

Several studies have shown that face identification accuracy is lower in older than younger adults. This effect of aging might be due to age differences in holistic processing, which is thought to be an important component of human face processing. Currently, however, there is conflicting evidence as to whether holistic face processing is impaired in older adults. The current study therefore re...

Currently microalgae are considered as an efficient biological producer of oil.Present study was conducted to explore the lipid yield percentage three microalgal strains Chlorellasp., Oedogonium sp. and Spirogyra Bligh Dyer, Soxhlet, Folch Microwave assistedextraction methods were employed for oil extraction. It observed that Dyer method withChloroform-methanol (1:2, v/v) gave maximum extractio...

A standardized extract of the plant Caralluma fimbriata (SlimalumaTM) is widely used in the management of obesity but its mode of action is not yet clarified. This study investigated the ability of Caralluma fimbriata extract (CFE) to modify pre-adipocyte cell division and thus the development of hyper-plastic obesity. Mouse 3T3-L1 pre-adipocyte cell line samples were treated with different con...

Three vegetable dyes are used for the study: anthocyanin dye from pomegranate arils extract, betalain dye from beet root extract and chlorophyll dye from tridax procumbens leaf. The anthocyanin and betalain, anthocyanin and chlorophyll, betalain and chlorophyll dyes are blended in cocktail in equal proportions, by volume. This study determines the effect of different extraction concentrations a...

dispersive liquid liquid microextraction (dllme) combined with gas chromatography–mass spectrometry (gc–ms) was used for the extraction and determination of 13 polycyclic aromatic hydrocarbons (pahs) in mineral water samples. in this procedure, the suitable combination of extraction solvent (500 µl chloroform) and disperser solvent (1000 µl acetone) were quickly injected into the water sample (...
