This study examines the role of glucagon and insulin in the incorporation of N derived from N-labeled glutamine into aspartate, citrulline and, thereby, [N]urea isotopomers. Rat livers were perfused, in the nonrecirculating mode, with 0.3 mM NH4Cl and either 2Nor 5-N-labeled glutamine (1 mM). The isotopic enrichment of the two nitrogenous precursor pools (ammonia and aspartate) involved in urea...
in this study, the particleboard was made with rice husk and urea formaldehyde resin of 7, 8, 9 and 10 percent (based on dry weight of rice husk). to improve mechanism of bondability a definite amount of isocyanate resin is introduced to replace the same amount of urea formaldehyde resin. the effect of urea formaldehyde resin and diisocyanate content on bondability was evaluated by studying the...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
The application of organic fertilizers can improve soil fertility specifically on Inceptisol soils which are quite extensive but have problems with relatively low nitrogen nutrients so that the effort to overcome this is through addition matter into fertilization or inorganic fertilizers. purpose study was determine effect goat and urea fertilizer chemical properties inceptisols from Rantau Sel...
Limited information exists on the impact of addition 28% urea ammonium nitrate (UAN) to 2,4-D, applied preplant (PP) soybean, control multiple-herbicide-resistant (MHR) Canada fleabane. A total five field experiments were conducted over a two-year period (2020, 2021) in southwestern Ontario determine if MHR fleabane with 2,4-D ester PP can be improved by adding UAN spray solution. Glyphosate + ...
The asymmetric unit of the crystal structure of the title compound, C(8)H(9)ClN(2)O(2), contains four independent mol-ecules. The dihedral angles between the urea N-(C=O)-N planes and the benzene rings are 83.3 (3), 87.8 (1), 89.1 (1) and 17.5 (2)° in the four mol-ecules. Extensive N-H⋯O hydrogen bonding is present in the crystal structure.
In the crystal of the title compound, C(10)H(14)N(2)O, double supra-molecular layers of PhCH(2)CH(2)CH(2)NHC(O)NH(2) are formed parallel to the bc plane by inter-molecular N-H⋯O hydrogen bonding, with R(2) (2)(8) and R(2) (1)(6) motifs in the b- and c-axis directions, respectively. The mean plane of the C(ar)-C-C group makes a dihedral angle of 84.8 (2)° with the benzene ring.
