Abstract

The aim of this research is to identify the general level of teachers’ curriculum expectations in (geography subject as a model), as well as the significance of the difference in the level of teachers’ curriculum expectations in light of the gender variables (male, female), the years of service (10 years or less - more than 10 years), the level of attitudes of fourth-grade literary students towards geography, the level of congruence between teachers’ curriculum expectations and the attitudes of fourth-grade literary students towards geography in light of the variables, the general level of congruence and the level of congruence between teachers’ curriculum expectations and the attitudes of students in the fourth literary class towards geography, the level of congruence between teachers’ curriculum expectations and the attitudes of their students in the class fourth literary towards geography, the level of congruence between the expectations of male and female teachers (with 10 years of service 10 and less), the methodology and the attitudes of female students in the fourth literary grade towards geography, the level of congruence between the expectations of male and female teachers (with more than 10 years of service), and the methodology and attitudes of female and male students in the fourth literary grade towards the subject of geography. thus, The methodological expectations tool was applied to a random sample of teachers of geography with a total of (73) participants, while the tool for students’ attitudes towards geography was applied to a random sample of fourth-grade literary middle or secondary students, totaling (872) male and female students. The results showed that there is a positive significance in the curriculum expectations of the teachers of geography for the fourth preparatory literary class, As well as there is a significance difference according to the gender variable in the level of curriculum expectations of teachers in favor of males, there is significance difference according to the variable of years of service in the level of curriculum expectations of teachers in favor of those with service more than 10 years, there is a positive significance in the attitudes of the fourth literary students towards the geography subject, there is a relative match at the level (positive extrusive graph) between the two variables (Teachers’ curriculum expectations) and (the fourth grade literary students’ attitudes towards geography), there is a relative (general) match between the two variables and with a significant difference in favor of (curriculum teachers) among the study sample, there is a relative match between the two variables with a significant difference in favor of female teachers among the female students, there is a relative match between the two variables and a significant difference in favor of the teachers over the students, there is a causal match between the two variables and a significant difference in favor of teachers with service (10 years and less) among the study sample, and there is a relative match between the two variables and a significant difference in favor of teachers with service (more than 10 years) among the study sample, according to these results appropriate relevant recommendations and suggestions were presented.

Dielectrical and electrical properties of PVA-NaI composites
...Show More Authors

                The electrical characteristics of polyvinyl alcohol PVA doped with different concentrations (0, 1, 2, 3 and 4wt%) of sodium  iodide NaI powder were studied. The films are prepared using solution casting technique, in order to investigate the effect of sodium iodide NaI additions on the electrical properties of PVA host. The D.C conductivity measured by measuring the D.C electrical resistance using the Keithly Electrometer type 616C, and for different temperatures ranging from 30 – 70oC.

          The dielectric properties measured by measuring the capacitor and the loss

Morphology and Mechanical Properties of (Epoxy/PVC) Blend
...Show More Authors

Abstract

     In this research, the morphology and mechanical properties of (Epoxy/PVC) blend were investigated.  (EP/PVC) blend was prepared by manual mixing of epoxy resin with different weight ratios of (Poly vinyl chloride (PVC) after dissolving it in cyclohexanon). Five sheets of polymer blends in wt% included (0%, 5%, 10%, 15% and 20%) of PVC were prepared at room temperature. Tests were carried out to study some mechanical properties for these blends and compared with the properties of pure epoxy. The morphology of the prepared materials was examined to study the compatibility nature between the two polymers under work. It was found that the best ratio of addition is (20%) of PVC.

Synthesis and characterization of nanocrystalline copper sulfide powders
...Show More Authors

Nanocrystalline copper sulphide (Cu2-xS) powders were synthesized by chemical precipitation from their aqueous solutions composed of different molar ratio of copper sulfate dehydrate (CuSO4.5H2O) and thiorea (NH2)2CS as source of Cu+2, S-2 ions respectively, and sodium ethylene diamine tetra acetic acid dehydrate (EDTA) as a complex agent. The compositions, morphological and structural properties of the nanopowders were characterized by energy dispersive spectroscopy (EDS), scanning electron microscope (SEM), and X-ray diffraction (XRD), respectively. The compositional results showed that the copper content was high and the Sulfur content was low for both CuS and Cu2S nanopowders. SEM images shows that all products consist of aggregate o

This work contain many steps starting from esterification of isophthalic acid to yield diester compound [I] which was converted to their acid hydrazide [II], then the later compound reacted with ethylacetoacetate to yield pyrazol-5-one compound [III]. Afterword added acetyl chloride to give the compound [IV], the reaction of this compound with theiosemicarbazide led to produce a new carbothioamide compound [V], which was reacted with ethyl chloro acetate to yield the thioxoimidazolidin compound [VI]. The condensation reactions of this compound with different substituted aldehyde give new alkene derivatives [VII] ad. The synthesized compounds were characterized by melting points, FT-IR, 1H-NMR and Mass spectroscopy.

 In the present work polymer electrolytes were formulated using the solvent casting technique. Under special conditions, the electrolyte content was of fixed ratio of polyvinylpyrolidone (PVP): polyacrylonitrile (PAN) (25:75), ethylene carbonate (EC) and propylene carbonate (PC) (1:1) with 10% of potassium iodide (KI) and iodine I2 = 10% by weight of KI. The conductivity was increased with the addition of ZnO nanoparticles. It is also increased with the temperature increase within the range (293 to 343 K). The conductivity reaches maximum value of about (0.0296 S.cm-1) with (0.25 g) ZnO. The results of FTIR for blend electrolytes indicated a significant degree of interaction between the polymer blend (PVP and PAN)

Optical properties of ZnS and PEDOT thin films
...Show More Authors

Vanadium dioxide nanofilms are one of the most essential materials in electronic applications like smart windows. Therefore, studying and understanding the optical properties of such films is crucial to modify the parameters that control these properties. To this end, this work focuses on investigating the opacity as a function of the energy directed at the nanofilms with different thicknesses(1–100) nm. Effective mediator theories(EMTs), which are considered as the application of Bruggeman’s formalism and the Looyenga mixing rule, have been used to estimate the dielectric constant of VO2 nanofilms. The results show different opacity behaviors at different wavelength ranges(ultraviolet, visible, and infrared). The results depict that th
