With the rapid development of economy, heavy metal soil pollution causes ecosystem deterioration and raises serious concerns. Topsoil samples (n = 205) were collected to investigate characteristics, risk levels, sources metals in topsoil eastern Tibet. Heavy contents, such as As, Hg, Pb, Cr, Mn, Mo, Ni, Cu, Zn, Cd, tested, potential analyzed using correlational principal component analysis. The...
New ELISAs for detecting macroamylase or free autoantibodies to amylase were tested with 48 samples that had been characterized by gel chromatography and electrophoresis. The macroamylase ELISA, with anti-IgG or anti-IgA for detection, detected macroamylase in 28 of 33 samples known to contain macroamylase (85% sensitivity), whereas the ELISA for free autoantibody to amylase was positive for on...
Discoloration of raw or cooked tissue can occur from cell disruptions and blood migration caused by slow or variable chilling rates. Color parameters established by the Commission International D'Eclairage for measuring lightness, redness, and yellowness (L*, a*, and b* respectively) were determined on two groups (A and B) of uncooked and cooked leg quarters chilled at +4, 0, -3, -12, or -18 C....
This study combined finite element method (FEM) simulations and physical experiments to develop a novel cold bulging process, with the aim of studying mitigating quenching residual stresses in 2A14 tapered cylinder forgings. The samples underwent at different ratios (0–4.0%) evaluate stress reduction performance (via hole-drilling strain-gauge method) improvements their mechanical properties. F...

Effect of Gamma Radiation on Aflatoxin Load, Amino Acid and Fatty Acid Composition of Oryza Sativa L
Crops which are stored for more than a few days become a potential target for mould growth and mycotoxin formation by the species Aspergillus. The present study investigated an effective extraction, clean up and analysis methodology for aflatoxins, amino acids and fatty acid methyl esters (FAME) in rice (Oryza sativa L) samples collected from Faisalabad Division, Pakistan The extraction solvent...
Soil degradation during construction often results in soil loss through erosion and reduced vegetation establishment. Composted organic materials are used to restore health of compromised urban soils when planting trees shrubs; however, less is known about compost amendments for turfgrass The objective this trial was determine the effects differing incorporation rates two types on perennial rye...
Estimation and monitoring of soil organic carbon (SOC) stocks is important for maintaining productivity meeting climate change mitigation targets. Current global SOC maps do not provide enough detail landscape-scale decision making, allow tracking sequestration or loss over time. Using an optical satellite-driven machine learning workflow, we mapped (topsoil; 0 to 30 cm) under natural vegetatio...
