One of the approaches for increasing yield and reduction rice production costs is precision agriculture. Complete correct determination nutrition status paddy soils necessary in precise To compare fuzz y Boolean methods mapping nitrogen phosphorus, 370 compound samples were collected from 306 ha Rice Research Institute Rasht County plots with dimension 50 × 100 m. Total available phosphorus con...

Results of research into four-membered 2-halo-1,2λ⁵-oxaphosphetane phosphorus(V)-heterocycles are presented. The preparation of 2-halo-1,2λ⁵-oxaphosphetanes by reaction of P-haloylides with carbonyl compounds is described. The mechanism of asynchronous [2+2]-сycloaddition of ylides to aldehydes was proposed on the base of low-temperature NMR investigations. 2-Halo-1,2λ⁵-oxaphosphetanes were iso...

A UV-curable, flame-retardant monomer, DAPP (bis[di-acryloyloxyethyl]-p-tert-butyl-phenyl-phosphate), was synthesized based on BPDCP (4-tert-butylphenyl-dichloro phosphate) and HEA (2-hydroxy ethyl acrylate). DAPP was blended with regular bisphenol A epoxy acrylate (BAEA) in various ratios to yield various phosphorus contents. The TGA-IR (thermogravimetric analyzer interface with an infrared sp...

Biofertilizer Ning shield was composed of different strains of plant growth promotion bacteria. In this study, the plant growth promotion and root-knot nematode disease control potential on Trichosanthes kirilowii in the field were evaluated. The application of Ning shield significantly reduced the diseases severity caused by Meloidogyne incognita, the biocontrol efficacy could reached up to 51...

The chemoenzymatic synthesis of a Lewis basic phosphine-phosphine oxide organocatalyst from a cis-dihydrodiol metabolite of bromobenzene proceeds via a palladium-catalysed carbon-phosphorus bond coupling and a novel room temperature Arbuzov [2,3]-sigmatropic rearrangement of an allylic diphenylphosphinite. Allylation of aromatic aldehydes were catalysed by the Lewis basic organocatalyst giving ...

the tumors in which odontogenic differentiation is fully expressed are the odontomas. odontomas are considered as hamartomas rather than a true neoplasm. these tumors are composed of enamel, dentine, cementum and pulp tissue. it is most commonly associated with the eruption of the teeth. they are usually discovered on routine radiographic examination. in exceptional cases, the odontoma erupts i...

It has been shown (Owen, 1948 a, b) that thyroxine increases the percentage of phosphorus in cow milk without affecting the percentages of nitrogen or calcium. Experiments were therefore planned (for preliminary reports see Chanda & Owen, 1949a, b) with the object ofpartitioning the phosphorus in the milk of cows treated with thyroxine to find out whether any particular type of phosphorus compo...

Attempts to utilize the compound ethylenediphosphine as a ligand bonded to the metal rhodium were made with a view towards the synthesis of complexes useful for kinetic studies. The desired Rh(III) complexes were not produced. Instead a Rh(I) complex was postulated to have been formed. A general review of rhodium-phosphorus chemistry is given as well as some suggestions for possible synthetic r...
