The attention is focused on the main classes of anthelmintics. Mode of action of the anthelmintics and the anthelmintic resistance, and alternative methods for dehelminthization are discussed. A targeted search for new anthelmintic substances in the series of speculative parental hydrocarbons (benzene, indene, naphthalene, 1 H1-cyclopenta [a]-naphthalene and phenanthrene) is suggested to be pro...
In the presence of various catalysts (TiCl4, AlCl3, H2SO4), process obtaining a coumarone-indene-carbazole resin (CICR), which is produced from liquid products coal coking, and its subsequent use for bitumen modification was investigated. The influence catalyst type on yield modifying properties CICR (change in thermoplastic adhesive after adding obtained resins to them) studied. effect amount ...
Using methanesulfonic acid as a catalyst, a series of cyclododeceno[b]indene derivatives were synthesized by the cyclization of alpha-benzylcyclododecanones, which were prepared by the reactions of cyclododecanones with a variety of substituted benzyl chlorides or bromides using NaH as a base. Their structures were confirmed by mp, IR spectra, 1H-NMR, 13C-NMR, MS, and x-ray diffraction. The pre...
هدف از انجام این تحقیق مقایسه آمادگی جسمانی دانش آموزان شهری و روستایی در دبیرستانهای پسرانه شهرستان ساری است. در این تحقیق آمادگی عمومی جسمانی دانش آموزان دردو بخش قابلیتهای جسمانی و حرکتی مورد بررسی قرار می گیرد.
An efficient use of plasticizers in rubber compounds requires an understanding their miscibility behavior. Besides the chemical properties both and plasticizer, rigidity plasticizer plays important role for miscibility. The is investigated here using glass transition measured by differential scanning calorimetry broadband dielectric spectroscopy (BDS). Additionally, interfacial relaxation phase...
Recent literature kinetic studies revealed the importance of new mechanisms for polycyclic aromatic hydrocarbon (PAH) and soot inception beyond hydrogen–abstraction–acetylene–addition (HACA) hydrogen–abstraction–vinylacetylene–addition (HAVA) in combustion ethylene other hydrocarbons. Co-flow diffusion flame is a canonical used to investigate interaction between fluid dynamics PAH chemistry. In...
