Abstract The nanomaterial containing amphiphile‐stabilized mononuclear Cu(II) is developed. material characterized by various spectroscopic techniques, such as X‐ray absorption spectrscopy (XAS), high‐resolution transmission electron microscopy, nuclear magnetic resonance (NMR), UV‐vis, and infrared spectroscopies. Since the structural data for amphiphile‐bound center not available, a theoretic...

This study aims to characterize salmonid manures and to determine their potential use in agricultural soils. Sampling was carried out below salmon and trout cages in farms located in lakes and in the sea in the South of Chile during 2002-2003. Manure was analyzed for macronutrients, micronutrients and heavy metals. Results showed a high variability between samples and differences between sea an...

A field experiment was conducted to evaluate the different brands of zinc fertilizer produced and marketed in different areas of Bangladesh and their effect on nutrients content in rice (BRRI dhan 32). Among the nutrients; the content of N, S and Ca in grains and straw did not vary significantly, but the contents of P, K, Na, Mg, Zn, Cu, Fe and Mn in grain and straw varied significantly due to ...

BACKGROUND Deficiency of macro and micro-minerals in the ration of dairy cows adversely affects growth, milk production and reproduction efficiency. It is essential to examine mineral concentrations in feeds offered to dairy cows in practical farms. METHODS Two villages from each taluka were selected at random for taking representative samples of feeds, forages and hair. Within the village, h...

Cell-cell fusion between gametes is a defining step during development of eukaryotes, yet we know little about the cellular and molecular mechanisms of the gamete membrane fusion reaction. HAP2 is the sole gamete-specific protein in any system that is broadly conserved and shown by gene disruption to be essential for gamete fusion. The wide evolutionary distribution of HAP2 (also known as GCS1)...

Deuterium isotope effects were evaluated as a strategy to optimize the pharmacokinetics of 7-(3,5-dimethyl-1H-1,2,4-triazol-1-yl)-3-(4methoxy-2-methylphenyl)-2,6-dimethylpyrazolo[5,1-b]oxazole (NVSCRF38), a novel corticotropin-releasing factor receptor 1 (CRF1) antagonist. In an attempt to suppress O-demethylation of NVSCRF38 without losing activity against the CRF1 receptor, the protons at the...

The objective of the current study was to evaluate high levels dietary copper (Cu) on goat carcass traits and meat quality. Thirty-six French Alpine goats (18.43 ± 2.35 kg) were randomly assigned 6 treatments (basal diet with Cu at 0, 10, 20, 40, 80, 160 ppm) replications each. experiment carried out for 102 d. Plasma enzymes, slaughter variables not different (P > 0.05) between levels. in diet...

In this study, minor-addition elements such as Si, Co, Cr, W, Mo, and Ti were added to matrix to improve the wettability between the diamonds and Cu matrix. The pressureless liquid-phase sintering technique adopted in this study provides a low-cost method for producing diamond/Cu composites with high potential for industrial mass production. Thermal properties of the diamond/Cu-Ti composites fa...

Kandungan logam berat pada sedimen sungai Batang Agam segmen Kota Bukittinggi telah diidentifikasi. Sampel diambil aliran sepanjang 3 km 6 titik sampel. Enam sampel yang kemudian di uji XRF untuk mengetahui kandungan beratnya. Hasil menunjukan bahwa mengandung Cr, Mn, Fe, Ni, Zn, Cu, As dan Pb. Konsentrasi rata-rata Sungai sudah melebihi ambang batas tetapkan, yaitu Cr (206,6 ppm), Mn (3646,6 F...
