introduction: health care is one of the most important sectors in the development of each country and disparities in their distribution will reduce the level of development. the aim of this study was to examine the access to healthcare and degree of development in health care resources in the west of iran in 2011. method: this was a cross-sectional and retrospective study. the study setting was...

in the current paper,nanostructured nickel oxide (nio) were synthesized by co-precipitation method using nickel(ii) chloride hexahydrate (nicl2.6h2o) and sodium hydroxide (naoh) as starting material. structural, optical and magnetic properties of nanostructures were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), atomic force microscope (afm), uv–vis absorption; fo...

To better understand the influence of prepreg parameters such as surface roughness, fibres/matrix distribution (e.g. presence or absence pure matrix layer on surface) and initial crystallinity, two different carbon fibres/Poly-Ether-Ketone-Ketone prepregs are used to fabricate unidirectional laminate by Vacuum-Bag-Only (VBO) process. By an in-situ monitoring set-up, thickness temperature differ...

The changes of the morphology during heating and the degree of crystallinity of dry and hydrated starch granules are investigated using second harmonic generation (SHG) based Stokes polarimetry. A spatial distribution of various polarization parameters, such as the degree of polarization (DOP), the degree of linear polarization (DOLP), and the degree of circular polarization (DOCP) are extracte...

The glass properties and semi crystalline properties of polymers are observable by X-ray diffraction. Some previous works 1, 2, 3 were about determination of degree of crystallinity of sPS by various technologies, like for example DSC, XRD and Raman spectroscopy. The purpose of this paper is to show importance of Raman spectroscopy as analytical tool for the study of amorphous and semi-crystall...

The mechanisms underlying the biosynthesis of cellulose in plants are complex and still poorly understood. A central question concerns the mechanism of microfibril structure and how this is linked to the catalytic polymerization action of cellulose synthase (CESA). Furthermore, it remains unclear whether modification of cellulose microfibril structure can be achieved genetically, which could be...

7 A systematic study for the optimization of the deposition process of ZnO thin films grown by 8 DC magnetron sputtering at room temperature was carried out using different oxygen partial 9 pressures and deposition times. We have established a correlation between the oxygen partial 10 pressure, the chemical composition and the crystalline structure of the films. 11 Stoichiometric and highly ori...

Shear piezoelectricity was investigated in a series of composites consisting of increased loadings of single-wall carbon nanotubes (SWCNTs) in poly (γ-benzyl-L-glutamate), or PBLG. The effects of the SWCNTs on this material property in PBLG will be discussed. Their influence on the morphology of the polymer (degree of orientation and crystallinity), and electrical and dielectric properties of t...

In order to determine the effects of nitrogen fertilizer on grain quality and starch physicochemical properties japonica rice cultivars with different contents amylose, normal amylose content (NAC) low (LAC) were grown in a field, or without (WN). The relationships between content, eating also examined. Compared WN, (NF) significantly increased yield but markedly decreased weight. addition, pro...

Abstract. Flexible free standing polymer electrolyte films have been successfully prepared using a blend of poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) and poly(vinyl chloride) (PVC) doped with lithium perchlorate (LiClO4). The conductivity of the film was influenced by salt concentration and the degree of crystallinity. An optimum room temperature conductivity obtained was 2.10...
