Development of optimal location and design capacity of wastewater treatment plants for urban areas: a case study in Samawah city

Water, and related wastewater structures, are critical factors in the existence and the improvement of civilizations. Wastewater gathering and management has a considerable effect on the climate and economy at both regional and global level, and, accordingly, it is appropriate to advance actions that guarantee effective management for wastewater, particularly in urban areas. This research thus examined the environmental and economic aspects of proposed locations for wastewater treatment plants. Samawah city, located in the southern part of Iraq, was selected as a case study for the research methodology, and for research purposes, the studied city was divided into three main zones (1, 2, and 3) of sixteen areas. The Google Earth tool was used to calculate the lowest elevations in the studied zones in order to assess the suggested positions of treatment plants. Additionally, the WinQSB program was utilised to select the most appropriate positions for treatment plants based on data obtained from local government departments. These data include population, water consumption, and required lengths and subsequent cost of pipes. This research thus developed a new strategy for assigning the locations of wastewater treatment plants

Osmotic drug delivery system of valsartan

The objective of this study is to design and evaluate a new EOP called swellable elementary osmotic pump (SEOP) of the freely water soluble drug, amitriptyline hydrochloride (1 g /mL) by adding water swellable polymers in the core. The hydrophilic polymers included in the core retard the highly water soluble drug by producing hydrogel within the core, which may restrict and delay the solvent contact with drug molecules and may increase the diffusional length of the solvent to achieve a constant release rate. Thus, this technology can be exploited to achieve constant drug release at predetermined rate especially for highly water soluble drugs

A study on prescribing trends in respiratory tract infections in a tertiary care hospital

The drug utilization pattern of respiratory tract infections to assess the rational prescribing pattern at tertiary care teaching hospital, endorsing drugs by mark names may undermine a portion of the objectives of fundamental solution idea. Recommending by nonexclusive name causes the clinic drug store to have a superior stock control. This will likewise assist the drug store with purchasing drugs on contract premise, as the quantity of brands is less, in this manner decreasing the perplexity among drug specialists while apportioning. Bland medications are regularly more temperate than the marked ones. With respect to recommending of FDCs, Potential points of interest of FDC's incorporate lessened reactions, expanded patient consistence, cooperative energy and expanded adequacy and decreased cost, potential impediments incorporate unbendable settled measurements proportion, contrary pharmacokinetics, expanded harmfulness, doctor and drug specialist's obliviousness

Extraction and Characterization of A Chromosomal Stain From Black Mulberry (Morus Nigra)

A dark-blue chromosomal stain from Black Mulberry (Morus nigra) wasextracted using organic solvents including dioxane, n-hexane, petroleum ether andacetone. This extracted stain stained chromosomes satisfactory. In order toascertain purity of the extracted stain, it was compared spectrophotometery withthree commercial standards stains; they are Azur II Eosin, Giemsa’s andMethylene blue Stains using a 200-900nm Spectrophotometric scan at threedifferent concentrations (25, 50 and 100mg/ml).It was found that the second peaks produced by Azur II eosin and Giemsastain (as well as the single peak produces by Methylene blue) occupied the samearea occupied by the second peak of the extracted stain, which agree to somedegree of similarity. The extracted method proved to be an appropriate analyticaltechnique with hope that further trials can be carrying out to simplify theextracting of the stain in future researches and make it less expensive

Formulation and invitro evaluation of oral extended release microspheres of aceclofenac using various natural polymers

In the present work, bioadhesive microspheres of Aceclofenac using Sodium alginate along with Carbopol 934, Carbopol 971, HPMC K4M as copolymers were formulated to deliver Aceclofenac via oral route. The results of this investigation indicate that ionic cross-linking technique Ionotropic gelation method can be successfully employed to fabricate Aceclofenac microspheres. The technique provides characteristic advantage over conventional microsphere method, which involves an “all-aqueous” system, avoids residual solvents in microspheres. FT-IR spectra of the physical mixture revealed that the drug is compatible with the polymers and copolymers used. Micromeritic studies revealed that the mean particle size of the prepared microspheres was in the size range of 512-903µm and are suitable for bioadhesive microspheres for oral administration. The in-vitro mucoadhesive study demonstrated that microspheres of Aceclofenac using sodium alginate along with Carbopol934 as copolymer adhered to the mucus to a greater extent than the microspheres of Aceclofenac using sodium alginate along with Carbopol 971 and HPMC K4M as copolymers. The invitro drug release decreased with increase in the polymer and copolymer concentration. Analysis of drug release mechanism showed that the drug release from the formulations followed non-Fickian diffusion and the best fit model was found to be Korsmeyer-Peppas. Based on the results of evaluation tests formulation coded T4 was concluded as best formulation

SPARC 2017 retrospect & prospects : Salford postgraduate annual research conference book of abstracts

Welcome to the Book of Abstracts for the 2017 SPARC conference. This year we not only celebrate the work of our PGRs but also the 50th anniversary of Salford as a University, which makes this year’s conference extra special. Once again we have received a tremendous contribution from our postgraduate research community; with over 130 presenters, the conference truly showcases a vibrant PGR community at Salford. These abstracts provide a taster of the research strengths of their works, and provide delegates with a reference point for networking and initiating critical debate. With such wide-ranging topics being showcased, we encourage you to exploit this great opportunity to engage with researchers working in different subject areas to your own. To meet global challenges, high impact research inevitably requires interdisciplinary collaboration. This is recognised by all major research funders. Therefore engaging with the work of others and forging collaborations across subject areas is an essential skill for the next generation of researchers
