Sheets of Epoxy (EP) resin with addition of TiO2 of grain size (1.5μm, and 50nm) and weight percentage (1%, 3%, and 5%) were prepared. Discs of 20mm diameter and 3mm thickness were cut for dielectric measurements. Dielectric properties (dielectric constant, dispassion factor and electrical conductivity) over the frequency range 102 -106 Hz were measured.
Comparison was made between the effect of micro and nano particles of TiO2 on the dielectric properties of EP composites with different weight percentage. Epoxy composites with micro sized particles of TiO2 were observed to have the better values of dielectric properties.

The work aims to calculate pollutants gases concentration that are emitted from gasoline
engine Vehicles exhaust .These concentration are compared with emission limits in other
countries. These gases are carbon monoxide (CO), unburned or partially burned hydrocarbons
(HC), nitrogen oxides (NOx), lead oxides, particulate matter and soot.

The analysis of exhaust gases carried out by using the electronic exhaust gas analysis system (T156D). Which is maunfactured in Italy and operate with windows system. The results show decre

This study was aimed to investigate the possibility of using iron slag by product as reactive materials in the porous reactive barriers technologies to achieve the principles of sustainability. Results reveal that the maximum adsorption capacity of iron slag (=2.309 mg/g) can be calculated by Langmuir model because it is more representative for adsorption data. This means that the chem-sorption is predominant mechanism for sorption of lead ions where the dissolution of calcium oxide by hydrolysis and ion exchange can enhance the removal of lead ions by iron oxide surface sites. In addition, the results of continuous tests conducted for 140 hours certified that the longevities of the barriers is proportional straightforwardly with

The trail included three salicylic acid concentrations (100, 200 and 300 mg L^-1) in addition to control treatment (distilled water spraying) within main plots and three linseed cultivars (Syrian, Egyptian and Iraqi local) within sub plots. The results showed that the Syrian cv. produced the hi

An attempt was done to develop a micropropagation protocol for oak using embryo culture. Oak is considered a hard-to-root woody plant by conventional propagation methods, that’s why using tissue culture techniques is a very suitable alternative method. For oak embryo culture, WPM was used and found to be better than MS medium for embryo germination which gave 66.13%. As well as adding of GA₃ to the medium improved the germination rate of embryos (43.25% and 82.25 %). At initiation stage, WPM was used and found to be the best medium by giving the highest number of shoots/ explant which was 1.80, the highest number of leaves (15.17 leaves/ explant) and the longest shoots (1.42 cm) followed by MS medium then GD which ga

To evaluate the role of anti-inflammatory and analgesicof Iraqi pumpkin seed oil. The oil seed (25-100 mg / kg) were investigated using various experimental models for analgesic and anti-inflammatory benefit. Acetic acid and thermal induced models of pain were used to examine the anti-nociceptive property. Though models of oedema induced by carragenin were used to evaluate anti-inflammation. Results were reported from these studies that the extract prepared from Iraqi pumpkin seeds possess potential anti-inflammatory and analgesic activity when  compared with standard drug Diclofenac. Even though all the co

The element-substituted calcium Deficient hydroxyapatite samples were synthesized using liquid-phase precipitation method. Different element ions (Mg⁺², Zn⁺², and Cu⁺²) were added at constant ratio (5% wt.). The phase composition of the element-substituted calcium hydroxyapatite samples was investigated by using X-ray diffraction. A comparison with known characteristics of the synthetic ion-substituted forms of hydroxyapatite was conducted. It was determined, that the investigated materials are single-phase solid solutions of the element-substituted hydroxyapatite. By the methods of IR spectroscopy and Raman scattering (RS) it was discovered the dependence of incorporation of the carbonate anion t

In vivo genotoxicity was assessed by quantifying the incidence of micronucleated polychromatic erythrocytes in the bone marrow cells of mice that were administered different doses of P.ostreatus extract (150, 200,250, and 300 mg/kg/day( respectively, individually, and in combination with CP (40 mg/kg body weight) according to the following three experimental protocols (pre 2h, post 2h, and concomitant treatment for 14 day

  In this paper, we introduce and discuss an algorithm for the numerical solution of two- dimensional fractional dispersion equation.  The algorithm for the numerical solution of this equation is based on explicit finite difference approximation. Consistency, conditional stability, and convergence of this numerical method are described. Finally, numerical example is presented to show the dispersion behavior according to the order of the fractional derivative and we demonstrate that our explicit finite difference approximation is a computationally efficient method for solving two-dimensional fractional dispersion equation

The effects of reinforcing polymers with glass and graphite particles on enhancing their flexural properties are investigated.   Five composites were fabricated using the same polymer matrix material with different volume fractions of reinforcement particles. They comprise glass particles and graphite particles each  having volume fractions of 20% and 30% as well as a hybrid composite having 10% glass and 10% graphite. Three-point bending tests using a Universal Testing Machine were carried out on specimens of the above mentioned composites, as well as specimens of the polymer matrix material to determine their flexural properties. The experimental test results indicate that the flexural stiffness of all the composites wer
