The aim of this study was to access the Mn contamination in soil, forages, and animals. Heavy metal pollution is a matter prime significance natural environment. Through food chain, toxicity heavy metals their bioaccumulation potential are transferred into humans. Higher concentrations metallic compounds toxic living organisms but these essential maintain body metabolism. Intake crops polluted ...

Depletion of mineral reservoirs along with health and environmental concerns have led to a greater focus on bio-lubricants. The purpose this study was analyze optimize the reaction conditions transesterification process for cotton biolubricant synthesis by using Response Surface Methodology (RSM). In RSM, Rotatable central composite design selected examine effect input factors yield bio-lubrica...

This study investigated co-liquefaction of microalgae (Chlorella pyrenoidosa, CP) and lignocellulosic biomass (Rice husk, RH) in subcritical water for bio-oil production. The effects of liquefaction temperature (200-350°C), residence time (10-90min), solid concentration (10-30wt.%) and mass ratio of CP/RH on product distribution were investigated. The results showed that the highest yield of bi...

We have proposed a fruitful design principle targeting concentration ratio (CR) >1000× for typical high concentrating photovoltaics (HCPV) system, on account of two-concentrator system + homogenizer. The primary dual-lens concentrator unit, completely analogous basic optics seen in the superposition compound eyes, is trend not hitherto reported solar concentrators to our knowledge. Such cons...

BACKGROUND Succinic acid is one of the key platform chemicals which can be produced via biotechnology process instead of petrochemical process. Biomass derived bio-oil have been investigated intensively as an alternative of diesel and gasoline fuels. Bio-oil could be fractionized into organic phase and aqueous phase parts. The organic phase bio-oil can be easily upgraded to transport fuel. The ...

Abstract Intercropping of medicinal plants/legumes along with bio-fertilizer application is a relatively new sustainable practice for improving the yield and secondary metabolites production. Here, 2-years field experiment was performed to evaluate effects water deficit stress arbuscular mycorrhizal fungi (AMF) (as bio-fertilizer) on nutrients concentration, dry matter yield, essential oil quan...

BACKGROUND This study aimed to investigate new bone formation using recombinant human bone morphogenetic protein 2 (rhBMP-2) and locally applied bisphosphonate in rat calvarial defects. METHODS Thirty-six rats were studied. Two circular 5 mm diameter bony defect were formed in the calvaria using a trephine bur. The bony defect were grafted with Bio-Oss® only (group 1, n = 9), Bio-Oss® wetted ...

During recent years, experimental data, case reports, and epidemiological studies have suggested an important role for estradiol in bone metabolism in men. In a cohort of 596 men, aged 51-85 yr, we measured bone mineral density (BMD) of the lumbar spine, hip, total body, and forearm; serum levels of sex steroid hormones [total and free testosterone, total estradiol (17betaE(2)), bioavailable es...

Particle size distribution is a major factor in the health and climate effects of ambient aerosols, it shows large variation depending on prevailing atmospheric emission sources. In this work, particle number distributions air were investigated at suburban detached housing area northern Helsinki, Finland, during half-year period from winter to summer 2020. The measurements conducted with scanni...
