Synthesis of Some New Bis- 2, 3-Dihydroquinazolin-4(1H)-one Derivatives from Dapsone Drug and Investigating their Liquid Crystalline Properties and Antibacterial Activities
...Show More Authors

     During this paper, new Schiff's base derivatives [F1-F5] were prepared through the reaction of dapsone drug with different substituted benzaldehyde compounds. Schiff's bases were then converted into 2,3-dihyroquinazolin-4(1H)-one derivatives [F6-F10] through the reaction with 2-amino benzoic acid in ethanol. The synthesized compounds were identified by their physical properties using UV-Vis, FT-IR and 1H-NMR analyses. The liquid crystalline properties of some prepared compounds revealed smectic and nematic phases. Using two separate bacterial species, Pseudomonas aeruginosa (Gram -ve) and Staphylococcus  aureus (Gram +ve), the antimicrobial activities of certain synthesized compounds [F1,F2,F7,F8] were investigated using the agar diffusion process. The findings revealed that some of the assayed compounds had antimicrobial activities against the bacteria tested.

Prevalence of Some Parasitic Infections in Iraq from 2019 to 2020
...Show More Authors

      Parasitic infections are associated with low education, wars and migration, absence of animal control and poor sanitation. Infections like visceral and cutaneous leishmaniasis (VL and CL), trichomoniasis, toxoplasmosis, malaria, echinococcosis and schistosomiasis are all spread worldwide and have harmful effects on individuals and societies. The aim of this survey was to identify the possible association of these infections with spatial distribution (province/governorate) and patient demographics (age and gender). According to the data collected from the Iraqi National CDC from 2019 to 2020, the predominant parasitic infections in both years were trichomoniasis and CL, followed by echinococcosis, VL and toxoplasmosis. Iraq is

ON SOME SPECIES OF TUBULIFEROUS THRIPS (THYSANOPTERA: PHLAEOTHRIPIDAE) FROM BAGHDAD, IRAQ
...Show More Authors

Twelve species of Tubuliferous thrips, of the family Phlaeothripidae had been reported from Iraq. Two of these were reported previously, Haplothrips cerealis Priesner, by El-Haidari and Daoud 1971 and Haplothrips tritici kurdjumov by Al-Ali 1977 and the rest were recorded for the first time: these are Haplothrips hukkineni Priesner; Haplothrips subtilissimus (Haliday); Haplothrips reuteri Karny; Haplothrips jasonis Priesner; Haplothrips sallloumensis Priesner; Haplothrips pharao Priesner; Phlaeothrips sycomri Priesner; Karnyothrips flavipus (Jones); Karnyothrips melaleucus (Bagnall); Dolicholepta micrurus (Bagnall).

Clinical Evaluation of Some Biochemical Parameters from Patients in Heamodialysis Room
...Show More Authors

As a marker of systemic inflammation, raised (C-reactive protein (CRP)) concentrations which are still within the normal range have been associated with an increased inflammation of chronic renal diseases (CRD). The current study aimed to establish potential determinats of raised CRP concentrations in patients who treated in Heamodialysis room,then study the relationship between CRP& some biochemical parameters related CRD We used a CRP latex reagents Kit which is based on an immunological reaction between CRP antisera bounded to the biologically inert latex particles or with CRP in the test specimens of 19 patients with (CRD) mean age 48 years ,range = 30?65 & in 21 healthy subjects as control group their age range = 30 ?45 years.

Some Mechanical Properties of Concrete by using Manufactured Blended Cement with Grinded Local Rocks
...Show More Authors

The use of blended cement in concrete provides economic, energy savings, and ecological benefits, and also provides. Improvement in the properties of materials incorporating blended cements. The major aim of this investigation is to develop blended cement technology using grinded local rocks . The research includes information on constituent materials, manufacturing processes and performance characteristics of blended cements made with replacement (10 and 20) % of grinded local rocks (limestone, quartzite and porcelinite) from cement. The main conclusion of this study was that all types of manufactured blended cement conformed to the specification according to ASTM C595-12 (chemical and physical requirements). The percentage of the compress

Effect of silver nitrate incorporation into heat polymerized acrylic resin on some mechanical properties
...Show More Authors

Background: Polymers are very rarely used in their form. These modifications are carried out in order to improve the properties of polymers.Recently silver have been used successfully as antimicrobial (medical and dental) biomaterials that can prevent caries and infection of implants Purposes: The aim of the present in vitro study is to evaluate the effect of addition of silver nitrate to acrylic resin in different concentrationsthrough several tests part of these are: The effect of this additive on impact strength, transverse strength, and tensile strength of AgNO3 – loaded resin, and to assess any effect of addition of silver nitrate on coloration of acrylic resin. Materials and methods: Different concentrations of silver nitrate
