Tethering of Homo and Block Glycopolymer Chains onto Montmorillonite Surface by Atom Transfer Radical Polymerization

引用

Open Journal of Organic Polymer Materials 2012年第4期2卷 80-88页

作者： amal Amin Heba Kandil Ahmed Ramadan mohamed Nader Ismail Chemistry Department Faculty of Science Helwan University Cairo Egypt Polymers & Pigments Department National Research Center Giza Egypt

Well-defined homo glycopolymer/montmorillonite (MMT) nanocomposite (gly1) was prepared successfully by the “grafting from” technique from the modified surface of MMT via surface initiated atom transfer radical polymerization (SI-ATRP) of 3-O-methacryloyl-1,2:5,6-di-O-isopropylidene-α-D-glucofuranose (gly) in the presence of Cu(I)Br/ bi- pyridyl at 90?C in xylene. Well-defined diblock copolymers (gly2, gly3, gly4 and gly5) were also synthesized via the same technique by using comonomers of methylmethacrylate (MMA) or styrene (St) with glycomonomer (gly) using the same catalytic system. The formed nanocomposites showed both intercalated and exfoliated structures, as judged by XRD and TEM measurements. Further analyses were performed on such nanocomposites to confirm their formation such as TGA and DSC. The structures of the attached polymers to MMT were characterized by 1H NMR.

Pharmacology & Pharmacy 2014年第8期5卷 821-827页

作者： Suleiman Ibrahim Sharif Manar Abdulla amal Yousif Duaa mohamed Department of Pharmacy Practice & Pharmacotherapeutics M23-College of Pharmacy University of Sharjah Sharjah United Arab Emirates

Background: The present study was undertaken to evaluate the correct interpretation by university students of internationally available pictograms and to assess the ability of the pictograms to convey the intended messages. Aim: To compare the ability of pharmacy and non-pharmacy students to comprehend pharmaceutical pictograms. Method: Twenty eight internationally available (United States Pharmacopoeial Convention Inc. USP) pictograms were used throughout this study, which was conducted with 300 pharmacy and non-pharmacy students. Questionnaires included relevant questions, and participants were instructed to study the pictograms and write their interpretations. The American National Standards Institute requirement of 85% correctness criterion was used for correct interpretation. Differences between responses of the two groups were calculated using SPSS version 18 and p elpful for all patients. Out of the 28 pictograms 7 (25%) and 2 (7.1%) of them achieved the ANSI requirement of 85% correctness criterion by pharmacy and non-pharmacy students respectively. Conclusion: Interventions to increase public awareness of the usefulness of pharmaceutical pictograms are needed.

Transient Stability Analysis during an Improved Coupling Procedure for an Induction Generator Based Wind Generation System to the Grid

引用

International Journal of Modern Nonlinear Theory and Application 2014年第3期3卷 77-87页

作者： Soulaymen Kammoun amal Marrekchi Souhir Sallem mohamed Ben Ali Kammoun Commande des Machines electriques et Réseauxde Puissance (CMERP) University of Sfax Sfax Tunisia

For fixed speed wind turbines, the connection of its squirrel cage induction generator (SCIG) to the grid leads to inrush current which can reach an average of 2 p.u. up to 2.5 p.u. in higher wind speed even by using a soft starter. We propose in this paper a new soft starting of squirrel cage induction generator based wind turbine connected to the grid. Our strategy overcomes such transient instability problems and pinpoints rapidly synchronous speed regardless the wind speed acting on pitch angle. The proposed strategy ensures at least 50% reduction of inrush current and 18% gain of WTG starting time. A state model of the system is given including the wind turbine model and the SCIG model in the synchronous reference frame. Simulation results are analysed and compared to the classic coupling procedure.

Journal of Biosciences and Medicines 2020年第4期8卷 69-80页

作者： Reem Dbas Alharbi amal Hussain Mohammed Ali Ahmad Almatroudi Shaimaa mohamed Department of Medical Laboratories College of Applied Medical Sciences Qassim University Qassim KSA Alrass General Hospital Qassim Health Cluster Saudi Ministry of Health Qassim KSA

Hospital-acquired infections (HAI) reflect as a major global safety concern for both patients and health-care professionals. These infections could be in the form of cross-infection, endogenous infection and environmental Infection. Over 80% of these infections are related to devices’ utilization needed for patients’ life support. Methods show this is an observational and cross-sectional study, to identify the microorganism and determine the potential source of transmitting of hospital acquired infection by routine devices in adult ICU. The samples were collected using Amies transport media;three swabs were taken from the surfaces of indwelling urinary catheter, mechanical ventilation device and central venous catheter used from every twelve patients. The samples were cultured and analyzed by using microbiologic technique. Finally, all samples analyzed by MicroScan WalkAway 96 pulse. Results showing the most bacteria isolated are “Klebsiella pneumonia” (18.37%), “Acinetobacter baumannii” (11.48%), “Staphylococcus epidermidis” (4.59%), “Staphylococcus haemolyticus” (4.59%), “E. coli” (4.59%), “Serratia marcescens” (2.3%), “Pseudomonas luteola” (2.3%), “Kocurio kristinae” (2.3%) and “Photorhabdus luminscens” (2.3%). This study detects a high contamination of routine devices and resistant organisms. In the end it is recommended that effective infection control practices and effective strategies to control antibiotic-resistant bacteria should be applied.

The last decade has seen a noticeable advance in diagnosing and treating infertility, however, the overall incidence has remained the same, with an estimated 40% - 50% resulting from factors related to the female [1]. Unexplained infertility where the cause remains elusive, still accounts for up to 30% of cases. Increasing evidence demonstrates the significant of antioxidants in all physiological and biochemical processes in humans, including human reproduction.

Removal of Some Toxic Ions from Seawater and Wastewater by Sorption onto Natural, Synthetic Hydroxyapatite and Alginate-Hydroxyapatite Composite Nanoparticles: A Comparative Study

引用

Journal of Environmental Protection 2019年第9期10卷 1155-1173页

作者： mohamed A. Shreadah Osama E. M. Rizk mohamed A. Aly-eldeen amal R. Rashad mohamed E. Mahmoud National Institute of Oceanography and Fisheries Alexandria Branch Alexandria Egypt Chemistry Department Faculty of Science Alexandria University Alexandria Egypt

The main objective of this paper is to study the removal of Cadmium(II), Lead(II), Chromium(VI), and Mercury(II) ions by sorption onto different natural and synthetic nanoparticles. Special attention has been given to the application of fish bone in nanoform as a useful, inexpensive and eco-friendly alternative material. A comparison between natural hydroxyapatite (fish bone), synthetic hydroxyapatite nanoparticles (HAP) and alginate-hydroxyapatite composite (Alg/Hap) to assess their removal efficiencies to remediate the selected heavy metals has been done. Surface characterization by using different techniques has also been performed to understand the influence of surface characteristics of the adsorbent materials in the removal process. Different parameters (pH, contact time, mass dose and metal ion concentration) have been examined to identify the optimum conditions for remediation of different metals from polluted water. The potential applications of the biosorbents for removal and sorption of these metal ions from seawater and wastewater samples were also investigated and evaluated.
