Al-Mustansiriya University is a university in Baghdad, Iraq.The original Mustansiriya Madrasah, was established in 1227 by the Abbasid Caliph Al-Mustansir and was one of the oldest universities in the world. Its building, on the left bank of the Tigris River, survived the Mongol invasion of 1258 and has been restored.The modern Al-Mustansiriyah University was established with the help and financial support of the Republic of Ίrāq Teacher’s Union in 1963, mainly providing evening courses. In 1964, the University was given the status of a semi-state institution and some state financial support. At the same time it absorbed Al-Sha’ab University, another private university that had been founded by the Ίrāqi Association of Economists, and then moved to a new campus to the north of the city centre. Initially, the University also managed colleges in Mosul and Basra.In 1966 a law was passed under which the private universities were converted into public universities. Al-Mustansiriyah thus became, briefly, a College within the University of Baghdad. In 1967 a major reorganisation of higher education was initiated, with the intention that by 1969 all previous institutions would be abolished and reconstituted. Al-Mustansiriyah was designated as a separate University in 1968, and its branch campuses were detached to form part of the University of Mosul and the University of Basra. Wikipedia.

Capability of Rice Husk (RH) on the removal of four types of dyes pollutant from wastewater which were methylene blue, Congo red, brilliant green and crystal violent using different design parameters by adsorption process is focus on. The design parameters studied to adsorb above four dyes using RH as an adsorbent material were initial concentration of dye, absorbance material packing height which was RH, pH of dye solution feed inlet, treatment time, feed flow rate and feed temperature, these parameters were varied from (1-100) mg/l, (10-100) cm, (1-8), (1-60) min, (5-100) ml/min and (20-55°C) respectively. Results show that the higher removal efficiency was (95.81, 93.44, 96.62 and 96.35) % for brilliant green, Congo red, crystal violent and methylene blue dyes respectively from aquatic solution and these efficiencies were decreased with increasing of initial concentration and flow rate while the removal efficiencies increased with increasing absorbance material bed height and feeding temperature. The removal efficiency was increased with increasing pH of solution for methylene blue, brilliant green and crystal violent dyes and decreased with increasing pH of solution for Congo red dye. Statistical model is achieved to find an expression combined all operating parameters with the removal efficiency for dyes used in this paper in a general equation. By this way we can possess different benefits which are: remove the toxic dyes contaminated the water, get rid of agricultural waste RH.

The new ligand [N, N`-bis (3-methyl-2-benzothiazilidene) thiocarbamide] [BTC]. [BTC] its complexes with some trivalent metal ions [Cr, Fe, Rh and Ru]. Structures of the new compounds were characterized by elemental and thermal analyses as well as FT-IR and UV-Vis spectra. The magnetic properties and electrical conductivity of metal complexes were also determined. Study of the nature of the complexes formed in ethanol following the mole ratio method. The stability constant of the complexes have been studied with the time, as well as the molar absorptivities have been calculated. The work also include a theoretical treatment of the formed complexes in the gas phase, this was done using the (hyperchem-8) program for the molecular mechanics and semi-empirical calculations. The heat of formation (ΔHf°), binding energy (ΔEb) and total energy (ΔET) for ligand and their complexes were calculated by (PM3) method at 298 K°. The electrostatic potential of the ligand [BTC] was calculated to investigate the reactive sites of the molecules. PM3 were used to evaluate the bond length, vibrational and electronic spectra for the ligand [BTC] and their metal complexes then comparing with the experimental values. The antibacterial activity for the [BTC] and its metal complexes were studied against two types of pathogenic bacteria (Pseudonomous aerugionosa, as gram negative) and (Staphylococcus aurous, as gram positive). The minimal inhibitory concentrations (MIC) have been also studied to determine the low concentration for inhibition. Two antibiotics (Ampicillin and Amoxicillin) have been chosen to compare their activity to those of the new compounds. The results showed higher activity of the new compounds relative to the chosen antibiotics. Furthermore, the antifungal activity against (Candida albicans) and (Aspergillus flavus) were also studied for [BTC] and their metal complexes. © 2016, Sphinx Knowledge House. All Rights Reserved.

In this study, three different brackish surface water qualities, which represented the water quality in the Iraqi marshes, were simulated and used as feed waters to run a flat sheet reverse osmosis (RO) membrane system. The performance of three different types of the RO membrane (Thin-Film Composite (SE), Cellulose Acetate (CE), and Polyamide (AD)), under these water qualities, was investigated. The effect of the high and low feed water temperature (37. °C and 11. °C) on the operation efficiency of the three RO membranes was also investigated. In addition, using the Microfiltration (MF) membrane to pretreat the feed water and its effect on the performance of the RO membrane was examined. The results revealed that the SE membrane produced the highest permeate flux, while the AD membrane produced the lowest permeate flux in all three feed waters. Also, the elemental analyses showed that the CE membrane had the least rejection percentage (from 91.1% to 99.2%), but the AD membrane had the highest rejection percentage (from 97.6% to 99.5%) for all the existing feed water ions. Moreover, using the MF membrane increased the permeate flux, particularly of the runs conducted with a high temperature, and slightly improved salt ions rejection ratios by the RO membranes. Additionally, all membranes at the temperature of 37. °C exhibited higher permeate fluxes than those of corresponding membranes at a lower temperature (11. °C). © 2013 Elsevier B.V.

The free -COOH present in NSAIDs is thought to be responsible for the GI irritation associated with all traditional NSAIDs. Exploitation of mutual prodrugs is an approach wherein the NSAID is covalently bounded to a second pharmacologically active carrier/drug with the ultimate aim of reducing the gastric irritation. In this study some NSAIDs were conjugated with gabapentin via ester bonds using glycol spacers with the expectation of reducing gastric adverse effects and obtaining synergistic analgesic effects. The kinetics of ester hydrolysis were studied in two different non enzymatic buffer solutions at pH 1.2 and 7.4, as well as in 80% human plasma using HPLC with chloroform -methanol as mobile phase. Compounds 9a-c with ethylene glycol spacers showed significant stability at buffer solutions with half lives ranging from about 8-25 h, while the underwent a reasonable plasma hydrolysis (49%-88%) in 2 h. Compound 9d with a propylene glycol spacer shows a higher rate of enzymatic hydrolysis than the corresponding ethylene glycol compound 9c. The result of compounds 9a-c indicate that these compounds may be stable during their passage through the GIT until reaching the blood circulation. © 2012 by the authors; licensee MDPI, Basel, Switzerland.

Background: Observational studies indicate that higher vitamin C intake is associated with reduced risk for cardiovascular diseases. However, randomised controlled trials (RCT) examining the effect of vitamin C on endothelial function (EF) have reported inconsistent results. The aims of this systematic review and meta-analysis were to determine the effect of vitamin C supplementation on EF and to investigate whether the effect was influenced by health status, study duration, dose and route of vitamin C administration. Methods: We searched the Medline, Embase, Cochrane Library, and Scopus databases from inception to May 2013 for studies that met the following criteria: 1) RCT with adult participants, 2) vitamin C administered alone, 3) studies that quantified EF using commonly applied methods including ultrasound, plethysmography and pulse wave analysis. Results: Pooling the data from 44 clinical trials showed a significant positive effect of vitamin C on EF (SMD: 0.50, 95% CI: 0.34, 0.66, P<0.001). Stratification of the analysis by health outcome revealed improved EF in atherosclerotic (SMD: 0.84, 95% CI: 0.41, 1.26, P<0.001), diabetic (SMD: 0.52, 95% CI: 0.21, 0.82, P<0.001) and heart failure patients (SMD: 0.48, 95% CI: 0.08, 0.88, P<0.02) after vitamin C supplementation. The effect size appeared to be unaffected by study design, duration, baseline plasma vitamin C concentration or route of administration of vitamin C. The meta-regression showed a significant positive association between vitamin C dose and improvement in EF (β: 0.00011, 95% CI: 0.00001, 0.00021, P=0.03). Conclusions: Vitamin C supplementation improved EF. The effect of vitamin C supplementation appeared to be dependent on health status, with stronger effects in those at higher cardiovascular disease risk.
