10-[40-(N-diethylamino)butyl]-2-chlorophenoxazine (DBCP) undergoes a reversible one-electron oxidation with cerium (IV) to form a pink coloured radical cation [DBCP ] in the presence of stoichiometric amounts [DBCP: Ce(IV) 1:1] of the reactants. The radical cation underwent a second oneelectron oxidation to form a brownish yellow coloured dication [DBCP2] in the presence of more than one equ...
Magnesium is the lightest of all the commonly used metals. It is one of the most abundant elements in the earth's surface, amounting to a mass fraction of c.a. 2.5 %. It has been prepared for industry as metal and alloy ingots; the latter are most often made with aluminum. Various magnesium-based alloys have been developed and mainly applied to transport facilities and mobile electric devices b...
The aim of this study was to investigate the effectiveness of a new experimental complex in diets of lactating cows. The scientific and economic experiments were conducted in conditions of a large industrial complex for milk production from cows of Holstein breed (Russia). Four groups of Holstein cows (third calving), 20 animals each, were formed to conduct an analog method research. The cows i...
Human pancreatic lipase (HPL) is a single-chain glycoprotein with a molecular weight of 48,000 Da (1) . Its concentration in the pancreas is approximately 9000-fold greater than in other tissues, and the concentration gradient between pancreas and serum is approximately 20,000-fold (2) . For full catalytic activity and greatest specifi city, the presence of bile salts (such as sodium deoxychola...
Several oxovanadium (IV) complexes of pyradoxamine (PM), pyridoxol (P), pyridoxal (PL), and glycinehydroxamate (GX) were obtained as a result of potentiometric data analysis using SUPERQUAD at I = 0.15 M NaCl and T = 25°C. Protonated, unprotonated and hydroxospecies were detected in solutions. No polymeric species of oxovanadium(IV) were found under the experimental conditions used. Differentia...
