Parasitic diseases including amoebiasis, blastocystosis, giardiasis, trichomoniasis, and schistosomiasis, are all globally wide spread with harmful consequences. The present study was carried out to provide information of the prevalence of these diseases in some regions of Baghdad. Objectives: to detect the prevalence of human pathogenic parasites in some regions of Baghdad in stool samples and urine samples, and to determine the most common age group affected. Methods: Data were collected from Al-Kindy Teaching Hospital and Medical City Teaching Hospital, in the lab of parasitology from November 2018 to May 2019. The present study included (400) sample, which were collected from patients at different ages of both genders, samples of the study were selected randomly, divided them into equal number of stool samples and urine samples. Results: The results of epidemiological study showed that the total number infected with Entamoeba Histolytica parasite was (168) positive samples with total percentage of (84%) in both of Al-Kindy Teaching Hospital and Medical City Teaching Hospital with a percentage of (100%,and 68%) respectively, followed by Blastocystis Hominis with total number of (22) positive samples and a percentage of (11%), and then Giardia lamblia with total number of (10) positive samples and a percentage of (5%). Males showed higher number and percentage of infection with E. histolytica, (97) case with percentage of (48.5%), while females were (71) case with percentage of (35.5%), while number and percentage of infection with B. hominis in males were (17) case with percentage of (8.5%), and females were (5) case with percentage of (2.5%), finally number and percentage of infection with G. lamblia in male (5) case with percentage of (2.5%), equal females were (5) case with percentage of (2.5%). The highest percentage of infection occurred among age group (20-29) years with percentage of (36%), while the lowest percentage of infection occurred among age group (1-9) years, and age group (60-69) years with percentage (1%), were detected in Medical City Teaching Hospital. Urine examination showed there were no parasites in urine samples. In conclusions Entamoeba Histolytica was the most prevalent parasite in our study, followed by Blastocystis Hominis, while Giardia lambilia was the least prevalent one. Also males were more affected than females to parasitic infections, and the most common age group affected was (20-29) years. While urine examination showed there were no parasitic infections in our study. The current study recommend using permanent stains, also making more studies including increasing in number of samples.
Bacteriocin is an important antimicrobial peptide that can be used in industrial and medical fields due to its characteristics of antibacterial, food preservation and anticancer activities. Fifty isolates of Bacillus sp were collected from different soil samples which were already recognized via morphological and biochemical identification process. The isolates were screened for bacteriocin production effective against Staphylococcus spp in order to select the highest producing isolate. The isolate NK16 showed the maximum bacteriocin production (80 AU/ml) which was further characterized as Bacillus subtilis NK 16 through using API identification system (API 20E and API 50CHB). Then, next step was to detect the optimal conditions for maximum

The study involved preparing a new compound by combining Schiff bases generated from compounds for antipyrine, including lanthanide ions (lanthanum, neodymium, erbium, gadolinium, and dysprosium). The preparation of the ligand from condensation reactions (4-antipyrinecarboxaldehyde with ethylene di-amine) at room temperature, and was characterization using spectroscopic and analytical studies ( FT-IR, UV-visible spectra, 1H-NMR, mass spectrometry, (C.H.N.O), thermogravimetric analysis (TGA), in addition to the magnetic susceptibility and conductivity measurement of the synthesis complexes, among the results we obtained from the tests, we showed that the ligand behaves with the (triple Valence) lanthanide ions, the multidentate

This paper compare the accurecy of HF propagation prediction programs for HF circuits links between Iraq and different points world wide during August 2018 when solar cycle 24 (start 2009 end 2020) is at minimun activity and also find out the best communication mode used. The prediction programs like Voice of America Coverage Analysis Program (VOACAP) and ITU Recommendation RS 533 (REC533 ) had been used to generat HF circuit link parameters like Maximum Usable Frequency ( MUF) and Frequency of Transsmision (FOT) .Depending on the predicted parameters (data) , real radio contacts had been done using a radio transceiver from Icom model IC 7100 with 100W RF

This study presents the debonding propagation in single NiTi wire shape memory alloy into linear low-density polyethylene matrix composite the study of using the pull-out test. The aim of this study is to investigate the pull-out tests to check the interfacial strength of the polymer composite in two cases, with activation NiTinol wire and without activation. In this study, shape memory alloy NiTinol wire 2 mm diameter and linear fully annealed straight shape were used. The study involved experimental and finite element analysis and eventually comparison between them. This pull-out test is considered a substantial test because its results have a relation with behavior of smart composite materials. The pull-out test was carried out by a u
