Blood lipids are important mediators of host defense during the acute phase of innate immunity. Parasites may induce significant changes in lipid parameters, as has been shown in vitro study where substitution of serum by lipid/cholesterol in medium and in experimental models (in vivo). Thus changes in lipid profile occur in patients that having active infections with most of the parasites. Toxoplasma cannot synthesize cholesterol and depends upon acquisition of low density lipoprotein (LDL)-derived from the host cell, via endocytosis mediated by the LDL receptor or the LDL receptor-related protein.The present study is conducted to evaluate the changes in lipid profile in T. gondii infected women.A total of patients included 87 aborted women who had positive test for toxoplasmosis and a two control groups (115 non toxoplasmosis women): The first control group (negative control) contains 88 apparently healthy women and the second control group (positive control) contains 87 aborted women, were registered from Al-Yarmouk Teaching Hospital in Baghdad. Both control groups had negative test for toxoplasmosis. These samples were collected between the period January 2009 and May 2010. Patients and controls women's had comparable age that ranged between 15-45 years old. Serum samples were collected from each woman in the three groups and then the Enzyme Linked Immunosorbant Assay (ELISA) and Lipid profile assays were performed by using two commercial kits. In the basis of ELISA test anti-T. gondii antibodies (IgG and IgM), detected in the patients sera, three types of toxoplasmosis were identified. These were; acute type, sub-acute type and chronic type. Most of patients had chronic type 75 (86.2%). There were significant decreased in the total cholesterol are 165.05 (control groups 212.44, 213.33 respectively), triglycerides 134.98 (control groups 173.81, 174.40 respectively), LDL 87.78 (control groups 137.32, 135.87 respectively) and vLDL values 26.99 (control groups 34.70, 34.60 respectively). In contrast, there was significant increased in HDL value (49.0) as compared with control groups (40.42, 38.78 respectively). Also the result indicated that there were no significant differences in lipid profile values between the three types of disease. Toxoplasma gondii had a role in changes lipid profile values in infected women which characterized by decrease in cholesterol and triglyceride and LDL with a significant increases in HDL level. Further studies needed to maintain the effect of duration of the toxoplasmosis (acute or chronic) on the changes in lipid profile.
This study aimed to statement jet stream and its impact in the anti-cyclone affecting the climate of Iraq. Through the use of simple correlation coefficient ( Pearson ) that there is a very strong relationship between high- Siberian and both of the jet stream especially during the winter or over the stations of North . Therefore we, observe the relationship be significant in most of the winter months , spring and autumn . Statistically significant , but are different between station and another station , while the study come to another Anti-ciyclon have a real ,significant and statistically relationship corrclation . But this relationship is less than which found in are much less it with the Siberian high , it depends on the type of stat

The research consists of three chapters: chapter one studies the methodological framework of the research; chapter two includes three units: unit one studies technologies of electronic communication including its concept, features and types; unit two studies electronic publications i.e. its concept and features; and unit three deals with designing the electronic websites .it ends with chapter three which is divided into two sections: section one studies the
One of the most significant elements influencing weather, climate, and the environment is vegetation cover. Normalized Difference Vegetation Index (NDVI) and Normalized Difference Built-up Index (NDBI) over the years 2019–2022 were estimated based on four Landsat 8 TIRS’s images covering Duhok City. Using the radiative transfer model, the city's land surface temperature (LST) during the next four years was calculated. The aim of this study is to compute the temperature at the land's surface (LST) from the years 2019-2022 and understand the link, between LST, NDVI, and NDBI and the capability for mapping by LANDSAT-8 TIRS's. The findings revealed that the NDBI and the NDVI had the strongest correlation with the

In this research (100* 40* 4 cm) solar cell panel was used in Baghdad at autumn season (2010), to get best solar cell panel angles experimentally, and then a mirror (40*50 cm) is use to concentrate incident sunlight intensity on a panel. At first case we get (Tilt angle ?P =60°and Surface Azimuth angle ?P =36°E) is the best angles and other case, we add a mirror at angle = 120° at bottom of panel, then we get output power (27.48watt) is bigger than without using a mirror (25.16watt). We can benefit from these cases in variety applications.
This study included the determination of mercury level in twelve samples of skin whitening cream available in local market in Baghdad by atomic absorption spectrophotometer ,all the samples analyzed was contained a detectable amount of mercury. The lowest concentration of mercury in the sample C (Top Shirley) was 0.482 μg/g, and the higher concentration was 29.54 μg/g in the sample J (Norseen) .It was also noted that the samples H (whitening speckle removing day cream) and K (whitening speckle removing night cream) did not mention in the label significance the name of the country of origin and date of the validity of the product.
