Cerebellum (cb) is the most important and sensitive part of the central nervous system (CNS) after cerebrum. The exposure to any infection during embryogenesis produces abnormalities in the cerebellum function and morphology that effect on behavioral of offspring later. In the present study we used 30 mature female pregnant albino rats divided in to three groups, each group contain 10 females: G1 was considered the control group received D.W only, while G2 group treated orally with (2mg/kg /day) suspension of silver nanoparticles (AgNPs) and G3 group treated orally with (20mg/kg/day) AgNPs. The embryos retrieved in different embryonic days from ED12 to ED21. In this study morphometric analysis was measured in the developing albino rats cerebellum after maternal exposure to two concentrations of AgNPs from preimplantation period until delivery . we measured the morphometric parameters (area, perimeter, anterior-posterior diameter APD and transverse diameter TD) of the selected embryonic days; ED12,ED15,ED18, and ED21 and retrieved the embryos from these days. The morphometric results in the control group(G1) showed that increased significantly (P≤ 0.05) in the area of the developing cerebellum from ED12 until reach the optimal level in the end of gestation at ED21 (14.0815mm2 to 18.969 mm2 respectively), perimeter (9.804 mm2 to 16.267 mm2) and TD (52.6308μm to 431.6 μm),while the APD value was increased significantly (P≤ 0.05) at ED12 and ED15 only (367.0041 μm, 454.011 μm )respectively but the orientation growth of the cerebellum decreased significantly (P≤ 0.05) at the later stage of the development at ED18 and ED21(364.48 μm, 225μm) respectively. In the present research both concentrations of the AgNPs (2mg and 20 mg/kg/ B.Wt) showed changes in the dimensions of the developing cerebellum cortex according to the studied morphometric parameters; in the 2 mg/kg/ B.Wt, the area of the developing cerebellum cortex was increased significantly (P≤0.05) from ED12 (47.437mm 2) and reached to maximum growth at ED18 (130.220 mm2), while it is growth inhibited at ED21( 68.909 mm2) compared to control group, the values of the developing cerebellum cortex perimeter increased significantly (P≤0.05) from ED12 until ED15 (0.964 mm 2, 2.548 mm 2) respectively compared to control group; TD values of the developing cerebellum cortex increased significantly (P≤0.05) from ED12 until ED15 also (259.341 μm,436.203 μm) respectively compared to control group. While the APD of the developing cerebellum cortex was decreased significantly (P≤0.05) during late development of the cortex at ED18 and ED21(330.415 μm, 131.5 μm) respectively as in the control group. In G3 group which treated with 20mg/kg/ B.Wt concentration of AgNPs, the similar results of area were showed as in the lower concentration, area of the developing cortex increased significantly (P≤0.05) from ED12(80.11mm 2) and reached to maximum growth at ED18(140.56 mm2) and lower after that. the values of the developing cerebellum cortex perimeter increased significantly (P≤0.05) from ED12 until ED15 (0.256 mm2, 0.543 mm2) respectively compared to control group; while in the APD and TD values the effect of the higher concentration of the AgNPs was more effect on these dimensions; APD values decreased significantly (P≤0.05) at ED15 (360.48 μm ) and not reach to the complete growth, also in TD values decreased at ED15 (400.5744 μm) and do not reach to maximum growth at end embryonic development compared to the embryonic development timing in the control group.
Collapsing building structures during recent earthquakes, especially in Northern and Eastern Kurdistan, including the 2003 earthquake in Cewlig; the 2011 earthquake in Van; and the 2017 earthquake near Halabja province, has raised several concerns about the safety of pre-seismic code buildings and emergency facilities in Erbil city. The seismic vulnerability assessment of the hospital buildings as emergency facilities is one of the necessities which have a critical role in the recovery period following earthquakes. This research aims to study in detail and to extend the present knowledge about the seismic vulnerability of the Rizgary public hospital building in Erbil city, which was constructed before releasing the seism

The problem of research is the need to find out the obstacles and difficulties facing women in accessing leadership positions at the University of Baghdad from their point of view. The importance of research comes from the importance of women in the university and their vital role in the development of society. The research objectives summarized the most important obstacles facing women Access to the leadership positions in the university and the relative weight of these obstacles as well as trying to identify differences in their view of these obstacles according to the variables of specialization (scientific, human) and the scientific title (Professor, Assistant Professor, Teacher, Assistant Lecturer).

The study of chronic toxicity at the doses 100, 300 and 600mg/kg body weight in male and female rats for 90 days, recorded no mortality. Treated animals showed a normal weight change compared with control. The parameters of male fertility showed a significant decrease in the weight of testis, epididymis and seminal vesicle as well as a reduction in the number and the motility of spermatozoids at treated groups by the doses 300 and 600 mg/kg body weight compared to control group.
Disturbances of lipid metabolism is a predisposing factor of cardiovascular diseases, which are accompanied by high mortality rates of the population - ischemic heart disease and ischemic stroke. Plant polysaccharides can be promising remedies for correction of lipid imbalance.
In this regard, the aim of the study was to assess the hypolipidemic activity of polysaccharides isolated from the leaves of mistletoe.
The test-object was the leaves of the white mistletoe (Viscum album L.) growing on the apple (Malus domestica Borkh.), and the pear (Pyrus communis L.). Polysaccharides (water-soluble polysaccharides and pectin substances) were quantitatively determined by the gravimetric method followed

Friction coefficient between BHA and wellbore is the main player of stick slip amount, which can be mitigated by support a good lubricators as additives in drilling mud.
Mathematical (or empirical) solves should be done through adjusting all parameters which supposed to reduce stick- slip as low as possible using different models, one of the main parameters is drilling mud. As per Nanoparticles drilling fluid is a new technology that offers high performance

Managing unstructured social media data is difficult. Noisy data is a challenge to sentiment analysis. Since over 50% of the sentiment analysis process is data pre-processing, processing big social media data is challenging too. If pre-processing is carried out correctly, data accuracy may improve. Also, sentiment analysis workflow is highly dependent. Because no pre-processing technique works well in all situations or with all data sources, choosing the most important ones is crucial. Prioritization is an excellent technique for choosing the most important ones. As one of many Multi-Criteria Decision Mak
