nanocomposite of zro2/zno was prepared under ultrasonic irradiation by sol gel process from directly mixing zirconium and zinc gels, and the mixture was placed under ultrasonic irradiation for 2 hours then aging time the filtrated composite gel was calcinated at 500°c for 3h in furnace. the precursor sol of zirconium was prepared from an aqueous solution of zrcl4 and zinc acetate dihydrated was...

a new dimeric orthopalladated complex was synthesized via reaction of 2,3-dimethoxy benzaldehyde oxime with palladium chloride and lithium chloride in methanol as solvent and sodium acetate as base at room temperature. the catalytic activity of this dimeric [pd{c6h2(-ch=noh)-(ome)2-2,3}(µ-cl)]2 complex as an efficient, air, and moisture tolerant catalyst was investigated in mizoroki–heck cross ...

fusarium solani wasisolated from diseased roots of common bean (phaseolus vulgaris) grown in fields which were severely infected with fusarium root rot of bean in markazi province of iran. specific pcr primer pairs were used for the identification and verification of f. solani (mart.) f.sp. phaseoli (burkholder) w.c. snyder and n.h. hans. spore suspensions of f. solani f.sp. phaseoli were subje...

a total of 300 one-day old male broilers (cobb 500) were randomly divided into four treatment groups. the groups comprised of 15 birds each, and were defined by diet and the birds in each group were fed 0 (control), 3, 5, or 7 kgy electron-beam irradiated diets. a total of 5 replicates were performed. the chemical composition of the diet was not affected by irradiation.irradiation doses of 5 an...

in this research, cobalt and nickel sulfide nanoparticles (nps) were grown on almcm-41 matrix by using ion exchange method. the prepared samples were irradiated by thermalized neutron that emitted from am-be source up to fluencies (7.9+e9n/cm2). after that, x-ray diffraction (xrd), uv-vis spectroscopy, fourier transform infrared (ftir), scanning electron microscopy (sem) and transmission electr...

background: this study was carried out to observe the radioprotective effects of rosemarinus officinalis leaves extract (roe) against radiation-induced histopathological alterations in liver of mice. materials and methods: adult swiss albino mice were exposed to 6 gy gamma radiation in the presence (experimental) or absence (control) of roe to study the qualitative and quantitative alterations ...

collagen is the major protein component of cartilage, bone, skin and connective tissue and constitutes the major part of the extracellular matrix. collagen type i has complex structural hierarchy, which consists of treepolypeptide α-chains wound together in a rod-like helical structure. collagen is an important biomaterial, finding many applications in the field of tissue engineering. it has be...

background: magnetic resonance imaging (mri) is a safe modality and useful in characterizing normal and abnormal bone marrow (bm). mri also presents a more global view of bm than biopsy therefore, it may provide a better understanding of hematologic disorders. the purpose of this study was to monitor radiation-induced alterations of bm in acute phase of irradiation (1-10 day after total body ir...

the dried nitrate-urea gels exhibit the combination of autoicatatric combustion behavior and ultrasonic, whichcan be used to synthesize the nanocatalyst ferrite powders. cu and ni unites nanocatalyst powders sithcomposition of caned], and nife204 were synthesized by a sol-gel auto catalnic combustion process. themolar ratio between metal ions and urea was 11.2. the sob gel process was done at 8...
