About

The Iraqi journal of science is a quarterly specified scientific journal issued by the Faculty of Science at the University of Baghdad. The members of the Editorial Board representing the Departments of Eight Scientific departments, college of science/ Baghdad University and its related units of research, all are professors, scientists with extensive experience and considerable skills in their field of science, as well as an advisory board in support composed of professors and scientists with great reputation in their field of science from other Colleges, universities, or research institutes. The specialty of publication includes the following fields:

1.Pure and Applied Physics.
2.Mathematical Sciences.
3.Computer Science and Information Technology.
4.Science of chemistry.
5.Bio-Science technologies.
6.Earth Sciences, geo-physics, and remote sensing.
7.Astronomy, Space Sciences, and Remote Sensing Unit.
8.Science and Research of tropical area

The visions, goals, and the mechanisms of the Iraqi Journal of Science is to publish scientific research sober in the areas of Applied and Pure Sciences and instructive Iraqi society, scientific research, scientific interest large to contribute to the development of various disciplines, which provides significant support to researchers in all scientific facilities to continue to support the development plans in Iraq.

NUTRITIONAL STUDY of Anthrenus flavipes (LECONTE). (COLEOPTERA:DERMESTIDAE) ON DIFFERENT FOOD MATERIALS

Abstract

Eight food materials were used. They affected differently the biology of this beetle. Females laid highest number of eggs when fed on raw wool (45 eggs), then on goats hair (40.4 eggs) lowest number of eggs (17.2) when fed on natural silk, and (18 eggs) on sheep hide. Larval duration was shortest on raw wool (78.4 days), then goats hair (84.8 days) and camels hair (91.8 days). It was largest on human hair (176 days) and natural silk (173 days). Larval mortality was lowest on goat’s hair (1%) then on raw wool (4%) and highest on natural silk (16%) and human hair (12%). Other material lies between them. These materials affected variably pupal duration, adult emergence. Adult longevity when beetles were fed, as larvae. Raw wool and goats hair was more favorable for the beetle’s biology where as natural silk and human hair were the least favorable. Other materials ranged between them. Protein content did not show any correlation between these contents and the results of this investigation.

Abstract

To estimate the prevalence of the thalassemia genes in Mosul city, a study was carried out on 375 persons randomly selected, from people attending three major hospitals in the city. A reduced mean cell volume (MCV) below 80 fl was used as screening test for thalassemia genes (e.g. hemoglobin, Hb. Electrophoresis, and finally blood Iron content). A total of 33 cases (8.8%) were found carrying thalassemia genes. From the above cases, 25 cases (6.7%) were beta-thalassemia trait 8 cases (2.1%) were alpha-thalassemia.

Abstract

Pollen of Phlomis spp. grown wildly in Iraq has been investigated for the first time, as a part of comparative study for the species of this genus. Description of these pollen were important in diagnosis of this spp., the study showed that pollen were isopolar and a single pollen is tricolpate, with reticulate surface, and spherical -subspherical, in polar view, and almost ellipsoid to shortly ellipsoid in equatorial view, but it was spherical in P. oliveri Bth.; The longest axis of the pollen is 48 um, thus all the species included in present study were of medium size. Pollen of P.oliveri was the smallest in size, while pollen of P.rigida Labill was the biggest. There is a table for result, also figures and diagrams for illustration

Abstract

This research carried out to estimate mobility three herbicides (Basta 20%, Weedoff 48%, Carbyne 12.5%) it might be reach on water table and polluted it. We definite the mobility by hydraulic conductivity it depends on liquid and soil feature. The samples collected from two locations Kefel was first one sandy soil belonged to Orthids group and second one was Mishkab clay soil belonged to Torrifluvents group. Soil columns had been prepared by three replicates to each one. So the H.CO determinated with constant head method to sandy soil and variable hydraulic gradient to clay soil. The H.CO measures made by two stages: 1-First stage treatments (3 soil herbicides vs control) 2- Second stage treatment (3 soil + herbicides + drying vs control). The results analysised by C.R.D. design with Dunnett's method to mean comparison it were : Carbyne > Water > Basta > Weedoff in sandy soil Water > Weedoff > Basta > Carbyne in clay soil It refers to Carbyne herbicide mobile by H.CO(0.57) cm.min-1 with significant deference (D0.05 = 0.12) vs other . It might be reach on water table as well as Weedoff succeeded by H.CO (0.05) cm.min-1 with (D0.05 = 0.122) vs others but that meant no risky than H.CO of control.

Abstract

In this paper the effect of light exposure duration on Anthracene solution in chloroform is studied. It is found that: the Anthracene solution change its color when it is exposed to light, and that its relative quantum efficiency, Φ, decreases as the light exposure duration, t, increases and this govern by following empirical equation:- Φ = 0.7918-0.0762 In (t)

Abstract

The rapid thermal annealing (RTA) of single crystal silicon solar cell using the radiation from a halogen lamp has been demonstrated. The electrical properties under dark and illumination conditions followed by RTA are presented. The maximum conversion efficiency and filling factor obtained after 600oC/20S RTA were 13% and 0.7 respectively.

Abstract

A variational-perturbation approach is invoked to study the effect of the environment potential around Fluoride ion on some important electronic properties. The dipole polarisability α, oscillator strength S(-2) and S (-1) and magnetic susceptibility χ are theoretically estimated for Fluoride ion in different potentials. Also we calculate these electronic properties in many Fluoride structure crystals such as CdF2¬, CaF2¬, PbF2¬, SrF2¬ BaF2¬, and LiF.

Abstract

Let R be an integral domain with quotient field K. A prime ideal P of R is called a strongly prime ideal of R if for each x, y  K, x y  P implies x  P or y  P. In this paper, we generalize this concept to submodules, thus we define strongly prime submodules and give some of their properties.

Abstract

Let R be a commutative ring with 1, and let Aut(R) denote the group of ring automorphisms of R. We will usually consider a group G Aut(R). In this paper we will study the relation between G- invariant ideals and their traces. Also we study C.P modules and C.F modules.

Abstract

In this paper we prove some theorems, the first states: If R is an almost Noetherian domain, then the following statements are equivalent: 1- R is an almost Dedekind domain. 2- A(B∩C)= AB∩AC, for all ideals A, B and C of R. 3- (A+B)(A∩B)= AB, for all ideals A and B of R and the second states: If R is an almost Noetherian domain which is not a field, then the following statements are equivalent: 1- R is a valuation domain. 2- The nonunits of R form a nonzero principal ideal of R. 3- R is integrally closed and has exactly one nonzero proper prime ideal. In addition to the above some other results are proved.
