E nveloped viruses acquire a lipid membrane when they bud across a cellular membrane during virus assembly. In cell entry, the viral membrane must be fused to the host-cell membrane to deliver the viral genome into the cytoplasm for replication. Membrane fusion is therefore an essential step in the life cycle of enveloped viruses, and a great deal of research in recent years has been directed a...
postcolonial feminism, also dubbed as third world feminism, is an innovative approach, demonstrating the way women of colonized countries suffer from both native patriarchies and imperial ideology. also due to this double-colonization, postcolonial feminists contend that third world women are subjected to both colonial domination of empire and male domination of patriarchy. while western femini...
Thin layers of ZnS in two different temperature conditions of 25 or 2000C and also with different thicknesses from 100nm to 600nm were prepared by physical vapor deposition. Absorption and also transmission spectra of the films were obtained to determine absorption coefficient, extinction constant and optical band gap of the films. It was found that by decreasing the substrate temperature or de...
Background and Objectives: Preparation and evaluation of nanocomposite films have become prevalent in recent years. Depending on the purpose of using the film, and considering the effects and interaction effects of nanomaterial and other modifiers on the film properties, the amounts of nanomaterials and modifiers should be optimized. The effects of montmorillonite (MMT), glycerol (GL), and thei...
this study investigates the strategies native english and persian speakers employ for expressing gratitude in different situations. the strategies of persian efl learners are also compared with english strategies in order to find the differences that may exist between these two languages. social status and size of imposition of the favor are social variables which are investigated in detail for...
the purpose of the present study is to find out whether bilinguals of khuzestan-arab origin or monolinguals of iranian origin code-switch during learning or speaking english and which group is more susceptible to code-switch. to this end, the students of 24 classes from high schools and pre- university centers were screened out, and interviewed and their voices and code-switchings were recorded...
abstract the influence of cation?? and anion?? interactions on the strength and nature of n…h hydrogen bond has been investigated by quantum chemical calculations in s-triazine…3hf complex. ab initio calculations were performed at mp2/6-311++g(d,p) level of theory. the natural bond orbital (nbo) analysis and the bader’s quantum theory of atoms in molecules (aim) were also used to elucidate t...
in this thesis, structural, electronical, and optical properties of inverse pervskite(ca3pbo) in cubic phase have been investigated.the calculation have been done based on density functional theory and according to generalized gradiant approximate (gga) as correlating potential. in order to calculate the configurations, implementing in the wien2k code have been used from 2013 version. first of ...
abstract this study tried to investigate whether there was any significant relationship between technical translation quality of the senior english translation students and their levels of verbal-linguistic, visual-spatial and interpersonal intelligences. in order to investigate the research questions, the researcher selected a hundred senior english translation students from three universitie...
objective(s): the aim of this study was to insert nitrofurazone in a chitosan membrane to be used as a wound dressing. materials and methods: several blend films using chitosan (cs) and polyvinyl alcohol (pva), containing nitrofurazone were prepared by means of casting/solvent evaporating technique. different characteristics such as mechanical properties, water vapor transmission rate (wvtr),...
