rats. The oral administration of 200 mg/kg, 400 mg/kg and 600 mg/kg, body weight of methanolic extract, one hour before induction of inflammation, exerted a significant inhibition effect of 47%, 57% and 62% respectively after 4h λ-carrageenan treatment and highly significant inhibition effect of 57%, 66% and 75% respectively after 8h λ-carrageenan treatment, compared to non treated group (100%) and that treated with aspirin, a standard anti-inflammatory drug. On the other hand, the effect of the plant extract on stomach was macroscopically and microscopically studied. The plant extract has an impact on the loss ratio of granulocytes that have invaded the stomach after a period of inflammation at a dose of 600 mg/kg body weight. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inflammation" title="inflammation">inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=Anacyclus%20pyrethrum" title=" Anacyclus pyrethrum"> Anacyclus pyrethrum</a>, <a href="https://publications.waset.org/abstracts/search?q=gastritis" title=" gastritis"> gastritis</a>, <a href="https://publications.waset.org/abstracts/search?q=Wistar%20Albinos%20rats" title=" Wistar Albinos rats"> Wistar Albinos rats</a> </p> <a href="https://publications.waset.org/abstracts/17054/evaluation-of-activity-of-anacyclus-pyrethrum-methanolic-extract-on-acute-inflammation-induced-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17054.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">487</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">11</span> A Clustering-Sequencing Approach to the Facility Layout Problem</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Saeideh%20Salimpour">Saeideh Salimpour</a>, <a href="https://publications.waset.org/abstracts/search?q=Sophie-Charlotte%20Viaux"> Sophie-Charlotte Viaux</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Azab"> Ahmed Azab</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Fazle%20Baki"> Mohammed Fazle Baki</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Facility Layout Problem (FLP) is key to the efficient and cost-effective operation of a system.

First, clusters of vertically aligned facilities are formed, which are later on sequenced horizontally. The developed methodology provides promising results in comparison to its counterparts in the literature by minimizing the inter-distances for facilities which have more interactions amongst each other and aims at placing the facilities with more interactions at the centroid of the shop. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clustering-sequencing%20approach" title="clustering-sequencing approach">clustering-sequencing approach</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20modeling" title=" mathematical modeling"> mathematical modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=optimization" title=" optimization"> optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=unequal%20facility%20layout%20problem" title=" unequal facility layout problem"> unequal facility layout problem</a> </p> <a href="https://publications.waset.org/abstracts/58494/a-clustering-sequencing-approach-to-the-facility-layout-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58494.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">333</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">10</span> The Fit of the Partial Pair Distribution Functions of BaMnFeF7 Fluoride Glass Using the Buckingham Potential by the Hybrid RMC Simulation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sidi%20Mohamed%20Mesli">Sidi Mohamed Mesli</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Habchi"> Mohamed Habchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arslane%20Boudghene%20Stambouli"> Arslane Boudghene Stambouli</a>, <a href="https://publications.waset.org/abstracts/search?q=Rafik%20Benallal"> Rafik Benallal</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The BaMnMF7 (M=Fe,V, transition metal fluoride glass, assuming isomorphous replacement) have been structurally studied through the simultaneous simulation of their neutron diffraction patterns by reverse Monte Carlo (RMC) and by the Hybrid Reverse Monte Carlo (HRMC) analysis. This last is applied to remedy the problem of the artificial satellite peaks that appear in the partial pair distribution functions (PDFs) by the RMC simulation. The HRMC simulation is an extension of the RMC algorithm, which introduces an energy penalty term (potential) in acceptance criteria. The idea of this work is to apply the Buckingham potential at the title glass by ignoring the van der Waals terms, in order to make a fit of the partial pair distribution functions and give the most possible realistic features. When displaying the partial PDFs, we suggest that the Buckingham potential is useful to describe average correlations especially in similar interactions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fluoride%20glasses" title="fluoride glasses">fluoride glasses</a>, <a href="https://publications.waset.org/abstracts/search?q=RMC%20simulation" title=" RMC simulation"> RMC simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20RMC%20simulation" title=" hybrid RMC simulation"> hybrid RMC simulation</a>, <a href="https://publications.waset.org/abstracts/search?q=Buckingham%20potential" title=" Buckingham potential"> Buckingham potential</a>, <a href="https://publications.waset.org/abstracts/search?q=partial%20pair%20distribution%20functions" title=" partial pair distribution functions"> partial pair distribution functions</a> </p> <a href="https://publications.waset.org/abstracts/38108/the-fit-of-the-partial-pair-distribution-functions-of-bamnfef7-fluoride-glass-using-the-buckingham-potential-by-the-hybrid-rmc-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38108.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">503</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">9</span> Epidemiological Profile of Healthcare Associated Infections in Intensive Care Unit</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdessamad%20Dali-Ali">Abdessamad Dali-Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Houaria%20Beldjillali"> Houaria Beldjillali</a>, <a href="https://publications.waset.org/abstracts/search?q=Fouzia%20Agag"> Fouzia Agag</a>, <a href="https://publications.waset.org/abstracts/search?q=Asmaa%20Oukebdane"> Asmaa Oukebdane</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramzi%20Tidjani"> Ramzi Tidjani</a>, <a href="https://publications.waset.org/abstracts/search?q=Arslane%20Bettayeb"> Arslane Bettayeb</a>, <a href="https://publications.waset.org/abstracts/search?q=Khadidja%20Meddeber"> Khadidja Meddeber</a>, <a href="https://publications.waset.org/abstracts/search?q=Radia%20Dali-Yahia"> Radia Dali-Yahia</a>, <a href="https://publications.waset.org/abstracts/search?q=Nori%20Midoun"> Nori Midoun</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Healthcare-associated infections are a real public health problem, especially in intensive care units. The aim of our study was to describe the epidemiological profile and to estimate the incidence of these infections at the intensive care unit of our teaching hospital. A prospective study was conducted, from June 2012 to December 2013. During this period, 305 patients having a duration of hospitalization equal or more than 48 hours were included in the study. In terms of the incidence of healthcare associated infections, nosocomial pneumonia occupied the first position with a cumulative incidence rate of 20.0%, followed by bacteremia (5.6%), central venous catheter infections (4%), and urinary tract infections (3%). In the case of isolated microorganisms, Gram-negative bacilli not enterobacteriaceae occupied the first place with 48.5%, followed by enterobacteria (32.1%). Acinetobacter baumannii was the most common germ (27.6%). Our study showed that the rate of health-care-associated infections was relatively high in the intensive care unit. A control program to reduce all infections is a priority for the Infection Control Associated Committee. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=epidemiological%20profile" title="epidemiological profile">epidemiological profile</a>, <a href="https://publications.waset.org/abstracts/search?q=healthcare%20associated%20infections" title=" healthcare associated infections"> healthcare associated infections</a>, <a href="https://publications.waset.org/abstracts/search?q=intensive%20care%20units" title=" intensive care units"> intensive care units</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20hospital%20of%20Oran" title=" teaching hospital of Oran"> teaching hospital of Oran</a>, <a href="https://publications.waset.org/abstracts/search?q=Algeria" title=" Algeria"> Algeria</a> </p> <a href="https://publications.waset.org/abstracts/72027/epidemiological-profile-of-healthcare-associated-infections-in-intensive-care-unit" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72027.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">301</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">8</span> Mathematical Modeling and Algorithms for the Capacitated Facility Location and Allocation Problem with Emission Restriction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sagar%20Hedaoo">Sagar Hedaoo</a>, <a href="https://publications.waset.org/abstracts/search?q=Fazle%20Baki"> Fazle Baki</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmed%20Azab"> Ahmed Azab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In supply chain management, network design for scalable manufacturing facilities is an emerging field of research. Facility location allocation assigns facilities to customers to optimize the overall cost of the supply chain.

A mathematical model is formulated to fully express the problem at hand and to solve small-to-mid range instances. A dedicated constraint has been developed to restrict emissions in line with the Kyoto protocol. This problem is NP-Hard; hence, a simulated annealing metaheuristic has been developed to solve larger instances.

The stoichiometric Nd₂Fe₁₄B hard magnetic alloy and Nd₃₃.₄Fe₆₂.₆Al₄ composition was produced by arc melting under argon atmosphere. The Nd₃₃.₄Fe₆₂.₆Al₄ alloy has added to the 2:14:1 hard magnetic alloy with 48% by weight, and melted again by arc melting. Then, it was heat treated at 600, 700 and 800˚C for 3h under vacuum. In AC magnetic susceptibility measurements, for the as-cast sample, the signals decreased sharply at 101 ˚C and 313 ˚C corresponding to the Curie temperatures of the two ferromagnetic phases in addition to Fe phase. For the sample annealed at 600 ˚C, two Curie points were observed at about 257˚C and at 313˚C. However, the phase corresponding to the Curie temperature of 101 ˚C was disappeared. According to the magnetization measurements, the saturation magnetization has the highest value of 99.8 emu/g for the sample annealed at 600 ˚C, and decreased to 57.66 and 28.6 emu/g for the samples annealed at 700˚ and 800 ˚C respectively. Heat treatment resulted in an evolution of the new phase that caused changes in magnetic properties of the alloys. In order to have a clear picture, the identification of these phases are being under the investigation by XRD and SEM–EDX analysis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=NdFeB%20hard%20magnets" title="NdFeB hard magnets">NdFeB hard magnets</a>, <a href="https://publications.waset.org/abstracts/search?q=bulk%20magnetic%20materials" title=" bulk magnetic materials"> bulk magnetic materials</a>, <a href="https://publications.waset.org/abstracts/search?q=arc%20melting" title=" arc melting"> arc melting</a>, <a href="https://publications.waset.org/abstracts/search?q=Curie%20temperature" title=" Curie temperature"> Curie temperature</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20treatment" title=" heat treatment"> heat treatment</a> </p> <a href="https://publications.waset.org/abstracts/67627/investigation-of-nd-al-fe-added-nd-fe-b-alloy-produced-by-arc-melting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/67627.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">284</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">6</span> ELF in the Classroom: Use of ELF and Its Effects on Speaking Anxiety in Turkish Tertiary Level EFL Setting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baki%20Dursun">Baki Dursun</a>, <a href="https://publications.waset.org/abstracts/search?q=Kemal%20Benk"> Kemal Benk</a> </p> <p class="card-text"><strong>Abstract:</strong></p> English as a Lingua Franca (ELF) has become an increasingly hot topic in many of the developing countries including Turkey. Likewise, in most of these expanding circle countries the way of teaching English has been redesigned in accordance with Lingua Franca Core. Admittedly, the focus was on Grammar-based teaching formerly; however, with the introduction of the ELF, the shift is now more on teaching speaking abilities and strategies of negotiation of meaning. However, there are several reasons for this shift, one of the major contributions stems from the teacher training programs offered by Turkish universities as M.A. programs. Therefore, the aim of this paper is to compare and contrast the similarities and divergences among the instructors who have taken ELF classes in their teacher-training program and those who have not. With a longitudinal design, for five months, classes of two different groups of teachers (ELF Group vs. Traditional Group) have been observed and three teachers have been selected for each group. During the observations, principles of Lingua Franca Core offered by Jenkins have been taken into account and used to form the rubric for the observations. After the five-month period, a Likert scale type questionnaire has been given to the students to explore their level of anxiety while speaking. Independent samples t-test have been administered to see the groups differences statistically. The results of the study will be presented during the conference. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ELF" title="ELF">ELF</a>, <a href="https://publications.waset.org/abstracts/search?q=teacher%20training" title=" teacher training"> teacher training</a>, <a href="https://publications.waset.org/abstracts/search?q=speaking" title=" speaking"> speaking</a>, <a href="https://publications.waset.org/abstracts/search?q=anxiety" title=" anxiety"> anxiety</a> </p> <a href="https://publications.waset.org/abstracts/45343/elf-in-the-classroom-use-of-elf-and-its-effects-on-speaking-anxiety-in-turkish-tertiary-level-efl-setting" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45343.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">323</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">5</span> Molecular Characterization of White Spot Syndrome Virus in Some Cultured Penaeid Shrimps of Coastal Regions in Bangladesh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Md.%20Baki%20Billah">Md.

This study was undermined to develop rapid detection method of WSSV. A total of shrimp samples 240 collected from the 12 shrimp farms of different coastal regions (Satkhira, Khulna, and Bagerhat) were analyzed by conventional PCR using VP28 and VP664 gene-specific primers. In satkhira, Bagerhat and Khulna 39, 41 and 29 samples were found WSSV positive respectively. Real-time PCR using 71-bp amplicon for VP664 gene correlated well with conventional PCR data. The prevalence rates of WSSV among the collected 240 samples were Satkhira 38%, Khulna 47% and Bagerhat 50%. Molecular analysis of the VP28 gene sequences of WSSV revealed that Bangladeshi strains phylogenetically affiliated to the strains belong to India. This work concluded that WSSV infections are widely distributed in the coastal regions cultured shrimp in Bangladesh.

Making the right decisions in production planning will affect directly the performance and productivity of a manufacturing firm, which is important for its ability to compete in the market. Therefore, developing and improving solution procedures for production planning problems is very significant. In this paper, we develop a Dantzig-Wolfe decomposition of a multi-item hierarchical production planning problem with capacity constraint and present a column generation approach to solve the problem. The original Mixed Integer Linear Programming model of the problem is decomposed item by item into a master problem and a number of subproblems. The capacity constraint is considered as the linking constraint between the master problem and the subproblems. The subproblems are solved using the dynamic programming approach. We also propose a multi-step iterative capacity allocation heuristic procedure to handle any kind of infeasibility that arises while solving the problem. We compare the computational performance of the developed solution approach against the state-of-the-art heuristic procedure available in the literature. The results show that the proposed heuristic-based decomposition approach improves the solution quality by 20% as compared to the literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=inventory" title="inventory">inventory</a>, <a href="https://publications.waset.org/abstracts/search?q=multi-level%20capacitated%20lot-sizing" title=" multi-level capacitated lot-sizing"> multi-level capacitated lot-sizing</a>, <a href="https://publications.waset.org/abstracts/search?q=emission%20control" title=" emission control"> emission control</a>, <a href="https://publications.waset.org/abstracts/search?q=setup%20carryover" title=" setup carryover"> setup carryover</a> </p> <a href="https://publications.waset.org/abstracts/112830/a-heuristic-based-decomposition-approach-for-a-hierarchical-production-planning-problem" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/112830.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">138</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Replacement of Dietary Soybean Meal by Dried Grains with Solubles on Liver Histology of Rainbow Trout, Oncorhynchus mykiss</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baki%20Aydin">Baki Aydin</a>, <a href="https://publications.waset.org/abstracts/search?q=Erkan%20Gumus"> Erkan Gumus</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The aim of the present study was to investigate the effects of replacing dietary soybean meal by dried grains with solubles (DDGS) on liver histology of rainbow trout, Oncorhynchus mykiss. Five isoproteic (∼45% crude protein) and isocaloric (∼3570 kcal/kg digestible energy) diets were formulated: Conrol-1 (Fish meal control), Control-2, DDGS33, DDGS66 and DDGS100 which included 0%, 0%, 10%, 20% and 30% DDGS, respectively. Triplicate groups of fish with an average weight of 20.46 g were fed three times a day until apparent satiation during 84 days. The obtained results showed that diameters of hepatocyte nuclei were not statistically different among the groups. The histological examination of liver sections from the fish fed the Control-1 diet showed normal histology, mild cytoplasm vacuoles and appears to be central to hepatocyte nuclei. Fish fed diets containing soybean meal and DDGS presented variable levels of cytoplasmic vacuolization and some with eccentric hepatocyte nuclei. But, fish fed diet soybean meal based control (Control-2) showed the highest hepatocyte nuclei displacement, and cytoplasm vacuoles compared the DDGS30 diet. DDGS20 and DDGS30 fish also showed more regular hepatocytes than in Control-2 fish. The results of this study demonstrated that fish fed diets containing increasing DDGS levels exhibited less histomorphological changes compared the Control-2 diet. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DDGS" title="DDGS">DDGS</a>, <a href="https://publications.waset.org/abstracts/search?q=soybean%20meal" title=" soybean meal"> soybean meal</a>, <a href="https://publications.waset.org/abstracts/search?q=rainbow%20trout" title=" rainbow trout"> rainbow trout</a>, <a href="https://publications.waset.org/abstracts/search?q=hepatocyte" title=" hepatocyte"> hepatocyte</a> </p> <a href="https://publications.waset.org/abstracts/83605/replacement-of-dietary-soybean-meal-by-dried-grains-with-solubles-on-liver-histology-of-rainbow-trout-oncorhynchus-mykiss" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/83605.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2</span> Synthesis and Characterization of Some Novel Carbazole Schiff Bases (OLED)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Baki%20Cicek">Baki Cicek</a>, <a href="https://publications.waset.org/abstracts/search?q=Umit%20Calisir"> Umit Calisir</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carbazoles have been replaced lots of studies from 1960's to present and also still continues. In 1987, the first diode device had been developed. Thanks to that study, light emitting devices have been investigated and developed and also have been used on commercial applications. Nowadays, OLED (Organic Light Emitting Diodes) technology is using on lots of electronic screen such as (mobile phone, computer monitors, televisions, etc.) Carbazoles were subject a lot of study as a semiconductor material. Although this technology is used commen and widely, it is still development stage. Metal complexes of these compounds are using at pigment dyes because of colored substances, polymer technology, medicine industry, agriculture area, preparing rocket fuel-oil, determine some of biological events, etc. Becides all of these to preparing of schiff base synthesis is going on intensely. In this study, some of novel carbazole schiff bases were synthesized starting from carbazole. For that purpose, firstly, carbazole was alkylated. After purification of N-substituted-carbazole was nitrated to sythesized 3-nitro-N-substituted and 3,6-dinitro-N-substituted carbazoles. At next step, nitro group/groups were reduced to amines. Purified with using a type of silica gel-column chromatography. At the last step of our study, with sythesized 3,6-diamino-N-substituted carbazoles and 3-amino-N-substituted carbazoles were reacted with aldehydes to condensation reactions. 3-(imino-p-hydroxybenzyl)-N-isobutyl -carbazole, 3-(imino-2,3,4-trimethoxybenzene)-N-butylcarbazole, 3-(imino-3,4-dihydroxybenzene)-N-octylcarbazole, 3-(imino-2,3-dihydroxybenzene)-N-octylkarbazole and 3,6-di(α-imino-β-naphthol) -N-hexylcarbazole compounds were synthesized.

An ideal wound dressing material should protect the wound from any contaminations of exogeneous microorganism. In addition, the dressing material should provide a moist environment through extraction of body fluid from the wound area. Recently, wound dressing electrospun nanofibrous membranes are produced by electrospinning from a polymer solution or a polymer melt. These materials have a great potential as dressing materials for wound healing because of superior properties such as high surface-to-volume ratio, high porosity with excellent pore interconnectivity. Melt electrospinning is an attractive tissue engineering scaffold manufacturing process which eliminated the health risk posed by organic solvents used in electrospinning process and reduced the production costs. In this study, antibacterial wound dressing materials were prepared from TPU (Elastollan 1185A) by a melt-electrospinning technique. The electrospinning parameters for an efficient melt-electrospinning process of TPU were optimized. The surface of the fibers was modified with poly(ethylene glycol) (PEG) by radio-frequency glow discharge plasma deposition method and with silver nanoparticles (nAg) to improve their wettability and antimicrobial properties. TPU melt-electrospun mats were characterized using SEM, DSC, TGA and XPS. The cell viability and proliferation on modified melt-electrospun TPU mats were evaluated using a mouse fibroblast cell line (L929). Antibacterial effects of theirs against both Staphylococcus aureus strain and Escherichia coli were investigated by disk-diffusion method. TPU was successfully processed into a porous, fibrous network of beadless fibers in the micrometer range (4.896±0.94 µm) with a voltage of 50 kV, a working distance of 6 cm, a temperature of the thermocouple and hot coil of 225–230ºC, and a flow rate of 0.1 mL/h. The antibacterial test indicated that PEG-modified nAg-loaded TPU melt-electrospun structure had excellent antibacterial effects and cell study results demonstrated that nAg-loaded TPU mats had no cytotoxic effect on the fibroblast cells. In this work, the surface of a melt-electrospun TPU mats was modified via PEG monomer and then nAg. Results showed melt-electrospun TPU mats modified with PEG and nAg have a great potential for use as an antibacterial wound dressing material and thus, requires further investigation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=melt%20electrospinning" title="melt electrospinning">melt electrospinning</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofiber" title=" nanofiber"> nanofiber</a>, <a href="https://publications.waset.org/abstracts/search?q=silver%20nanoparticles" title=" silver nanoparticles"> silver nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=wound%20dressing" title=" wound dressing"> wound dressing</a> </p> <a href="https://publications.waset.org/abstracts/23367/functionally-modified-melt-electrospun-thermoplastic-polyurethane-tpu-mats-for-wound-dressing-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23367.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">462</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response);
