objective: spinal cord injury (sci) causes inflammation, deformity and cell loss. it has been shown that melissa officinalis (mo), as herbal medicine, and dexamethasone (dex) are useful in the prevention of various neurological diseases. the present study evaluated combinational effects of dex and mo on spinal cord injury. materials and methods: thirty six adult male wistar rats were used in th...

background: silicon hydrogel bandage contact lenses are used to enhance epithelial healing, control surface-generated pain, and prevent epithelial erosions after refractive surgery. considering the importance of faster reepithelialization in preventing complications of photorefractive keratectomy (prk) and the fact that the features and specifications of these commercially-available lenses are ...

in order to improve uv and visible lights photocatalytic activities of the pure anatase tio2, a novel and efficient n-doped tio2 photocatalyst was prepared by sol-gel method. n-doped titania is prepared using triethylamine (with difference molar ratios) as the nitrogen source. the crystalline structure, morphology, particle size, absorbance and band-gap and chemical structure of n-doped tio2 wa...

supergene oxidation-leaching and secondary sulfide enrichment in the sarcheshmeh porphyry cu-mo deposit generated a supergene profile to depths of 20 to 80 meters with oxide ore reserve about 22 mt. @1.08% cu and sulfides ore [email protected]% cu. geochemical distribution and behavior of trace metals associated with cu namely mo, au, and ag in the supergene profile of the sarcheshmeh were po...

the effect of geometry and material of the micro/nano particle on contact mechanic for manipulation was studied in this work based on atomic force microscopy. hertz contact model simulation for eph biological micro particle with spherical, cylindrical, and circular crowned roller shape was used to investigate the effect of geometry on contact simulation process in manipulation. then, to validat...

Density pumpout and edge-localized mode (ELM) suppression by applied n=2 magnetic fields in low-collisionality DIII-D plasmas are shown to be correlated with the magnitude of the plasma response driven on the high-field side (HFS) of the magnetic axis but not the low-field side (LFS) midplane. These distinct responses are a direct measurement of a multimodal magnetic plasma response, with each ...

The paper is concerned with determining the influence of the laser treatment process on the properties of electro-spark deposited coatings. The properties were assessed by analyzing the coating microstructure, microhardness, residual stresses and corrosion resistance. The tests were conducted for Mo, Ti and Cu coatings (the anode) which were electro-spark deposited over the C45 steel substrate ...

An extensive study of Higher Alcohols Synthesis (HAS) from syngas using alkalized MoS2 catalysts supported on Carbon Nanotubes (CNTs) is reported. Up to 30wt.% of Mo and 8wt.% K are added to the CNTs by impregnation method. The catalysts were characterized by different methods and the performance of the catalysts was assessed in a micro-reactor. TEM images showed that mo...

Reaction of MoCl3(THF)3 with [Me2Si{NLi(Dipp)}2]2 (Dipp = 2,6-i-PrC6H3) afforded a triply bonded dimolybdenum complex 1,2-Mo2Cl2[Me2Si(NDipp)2]2 1, spanned by two Me2Si[N(Dipp)]2 ligands, thus resulting in a syn conformation. The air- and moisture-sensitive compound 1 was characterized by NMR spectroscopic, elemental, and single-crystal X-ray crystallographic analysis. Reduction of 1 by Na/Hg y...
