They are specially designed to release the drug in the vicinity of target tissue. The aim of this study was to prepare and evaluate polymethacrylic acid nanoparticles containing Zidovudine in different drug to polymer ratio by nanoprecipitation method. SEM indicated that nanoparticles have a discrete spherical structure without aggregation. The average particle size was found to be 120 ± 0.02 - 420 ± 0.05 nm. The particle size of the nanoparticles was gradually increased with increase in the proportion of polymethacrylic acid polymer. The drug content of the nanoparticles was increasing on increasing polymer concentration up to a particular concentration. No appreciable difference was observed in the extent of degradation of product during 60 days in which, nanoparticles were stored at various temperatures. FT-IR studies indicated that there was no chemical interaction between drug and polymer and stability of drug. The in-vitro release behavior from all the drug loaded batches was found to be zero order and provided sustained release over a period of 24 h. The developed formulation overcome and alleviates the drawbacks and limitations of Zidovudine sustained release formulations and could possibility be advantageous in terms of increased bio availability of Zidovudine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title="nanoparticles">nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=zidovudine" title=" zidovudine"> zidovudine</a>, <a href="https://publications.waset.org/abstracts/search?q=biodegradable" title=" biodegradable"> biodegradable</a>, <a href="https://publications.waset.org/abstracts/search?q=polymethacrylic%20acid" title=" polymethacrylic acid"> polymethacrylic acid</a> </p> <a href="https://publications.waset.org/abstracts/1479/preparation-and-evaluation-of-zidovudine-nanoparticles" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/1479.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">625</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">142</span> Study of Interaction between Recycled Asphalt Pavement (RAP) Material and Virgin Material</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=G.%20Bharath">G.

When RAP is mixed with virgin aggregates in the presence of fresh binder there will be partial blending in a hot mix asphalt mixture. A recent approach used by some researchers for studying the degree of blending of RAP binder with virgin binder has been adopted in this study. Dense Bituminous Macadam mix of Ministry of Road Transport of India with a nominal maximum aggregate size of 19 mm was studied. Two proportions of RAP-20% and 35% and two types of virgin binders – viscosity grade VG10 and VG30 were considered. Design binder contents were determined for all the four types of mixes (two RAP contents and two virgin binders) as per Marshall mix design procedure. The degree of blending of RAP and virgin binders was evaluated in terms of the complex modulus of the binder. Laboratory test results showed that with an increase in RAP content, the degree of blending decreases. Better blending was observed for softer grade binder (VG10). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blending" title="blending">blending</a>, <a href="https://publications.waset.org/abstracts/search?q=complex%20modulus" title=" complex modulus"> complex modulus</a>, <a href="https://publications.waset.org/abstracts/search?q=recycled%20asphalt%20pavement" title=" recycled asphalt pavement"> recycled asphalt pavement</a>, <a href="https://publications.waset.org/abstracts/search?q=virgin%20binder" title=" virgin binder"> virgin binder</a> </p> <a href="https://publications.waset.org/abstracts/24171/study-of-interaction-between-recycled-asphalt-pavement-rap-material-and-virgin-material" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24171.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">432</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">141</span> Disaster and Crisis Management Using Geographical Information System (GIS) during the Operation and Maintenance Stages of the Hyderabad Metro Rail in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sai%20Rajeev%20Reddy">Sai Rajeev Reddy</a>, <a href="https://publications.waset.org/abstracts/search?q=Ishita%20Roy"> Ishita Roy</a>, <a href="https://publications.waset.org/abstracts/search?q=M.%20Anji%20Reddy"> M.

Dowel bars are generally used to ensure sufficient degree of load transfer, in addition to the load transferred by aggregate interlock mechanism at the joints. Joint efficiency is the measure of joint quality, a major concern and therefore the dowel bar system should be designed and constructed well. The interaction between dowel bars and concrete that includes various parameters of dowel bar and concrete will explain the degree of joint efficiency. The present study focuses on the methodology of selecting contact stiffness, which quantifies dowel-concrete interaction. In addition, a parametric study which focuses on the effect of dowel diameter, dowel shape, the spacing between dowel bars, joint opening, the thickness of the slab, the elastic modulus of concrete, and concrete cover on contact stiffness was also performed. The results indicated that the thickness of the slab is most critical among various parameters to explain the joint efficiency. Further displacement equivalency method was proposed to find out the contact stiffness. The proposed methodology was validated with the available field surface deflection data collected by falling weight deflectometer (FWD). <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contact%20stiffness" title="contact stiffness">contact stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=displacement%20equivalency%20method" title=" displacement equivalency method"> displacement equivalency method</a>, <a href="https://publications.waset.org/abstracts/search?q=Dowel-concrete%20interaction" title=" Dowel-concrete interaction"> Dowel-concrete interaction</a>, <a href="https://publications.waset.org/abstracts/search?q=joint%20behavior" title=" joint behavior"> joint behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20numerical%20simulation" title=" 3D numerical simulation"> 3D numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/105004/quantification-of-dowel-concrete-interaction-in-jointed-plain-concrete-pavements-using-3d-numerical-simulation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105004.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">151</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">139</span> Investigation on Biomass as an Alternate Source for Power Generation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narsimhulu%20Sanke">Narsimhulu Sanke</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20N.%20Reddy"> D.

Cast-in-situ short concrete panels (short slabs) laid on a strong foundation consisting of a dry lean concrete base (DLC), and cement treated subbase (CTSB) will reduce the thickness of the concrete slab to the order of 180 mm to 220 mm, whereas JPCP was with 280 mm for the same traffic. During the construction of SPCP test sections on two Indian National Highways (NH), it was observed that the joints remain uncracked after a year of traffic. The undoweled and uncracked joints load transfer variability and joint behavior are of interest with anticipation on its long-term performance of the SPCP. To investigate the effects of undoweled and uncracked joints on short slabs, the present study was conducted. A multilayer linear elastic analysis using 3D finite element package for different panel sizes with different thicknesses resting on different types of solid elastic foundation with and without temperature gradient was developed. Surface deflections were obtained from 3D FE model and validated with measured field deflections from falling weight deflectometer (FWD) test. Stress analysis indicates that flexural stresses in short slabs are decreased with a decrease in panel size and increase in thickness. Detailed evaluation of stress analysis with the effects of curling behavior, the stiffness of the base layer and a variable degree of load transfer, is underway. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=joint%20behavior" title="joint behavior">joint behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=short%20slabs" title=" short slabs"> short slabs</a>, <a href="https://publications.waset.org/abstracts/search?q=uncracked%20joints" title=" uncracked joints"> uncracked joints</a>, <a href="https://publications.waset.org/abstracts/search?q=undoweled%20joints" title=" undoweled joints"> undoweled joints</a>, <a href="https://publications.waset.org/abstracts/search?q=3D%20numerical%20simulation" title=" 3D numerical simulation"> 3D numerical simulation</a> </p> <a href="https://publications.waset.org/abstracts/105020/3d-numerical-simulation-of-undoweled-and-uncracked-joints-in-short-paneled-concrete-pavements" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105020.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">181</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">137</span> The Temperature Influence for Gasification in the Advanced Biomass Gasifier</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Narsimhulu%20Sanke">Narsimhulu Sanke</a>, <a href="https://publications.waset.org/abstracts/search?q=D.%20N.%20Reddy"> D.

The XRD studies were carried out to understand the phase of the samples where we found a sharp peak of Rb-G at 26.470. UV-Spectroscopy of Graphene and Rb-modified graphene samples shows the absorption peaks at ~248 nm and ~318 nm respectively.

To overcome all these issues, we implemented a cloud space for storing the data, and it provides more security to the data. We can access the data with just using the internet from anywhere in the world. We implemented all these with the java using Net beans IDE. Once user uploads the data, he does not have any rights to change the data.

That is because of our sophisticated methods of transporting the data at very high speeds and to very long distances, within no time. That is also because we kept on changing the method of serving the connections as the no of connections kept on increasing, that has led to many methods like TDMA, CDMA, and FDMA, etc. in wireless communications. And also the areas, where the connections are provided are also divided into CELLS, which are the basic blocks for cellular communications. Along with the wireless network, providing a wired network in mobile phones would serve as a very good alternative and would divert the extra traffic of a cell, so that a CELL which is providing wireless network can operate more efficiently. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CDMA" title="CDMA">CDMA</a>, <a href="https://publications.waset.org/abstracts/search?q=FDMA" title=" FDMA"> FDMA</a>, <a href="https://publications.waset.org/abstracts/search?q=TDMA" title=" TDMA"> TDMA</a>, <a href="https://publications.waset.org/abstracts/search?q=CELL" title=" CELL"> CELL</a> </p> <a href="https://publications.waset.org/abstracts/16271/wired-network-services-in-mobile-phones" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/16271.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">486</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">129</span> Thermal Radiation and Chemical Reaction Effects on MHD Casson Fluid Past a Permeable Stretching Sheet in a Porous Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20Sunita%20Rani">Y.

However, most of the bitumen production plants in India are unable to produce the air-blown VG40 grade bitumen. This requires plant’s air-blowing technique modification, and often the manufactures finds it as uneconomical. In this context, stiffer grade bitumen can be produced if bitumen is modified. Gilsonite, which is naturally occurring asphalt have been found to be used for increasing the stiffness of binders.

Over the years, different researchers have investigated this issue from a variety of angles. The significant contributions of the key mathematicians over the time have been summarized in this article. To this end, we classify finite groups into three categories viz. (a) Groups for which the number of subgroups is less than |G|, (b) equals to |G|, and finally, (c) greater than |G|. Because every element of a finite group generates a cyclic subgroup, counting cyclic subgroups is the most important task in this endeavor. A brief survey on the number of cyclic subgroups of finite groups is also conducted by us. Furthermore, we also covered certain arithmetic relations between the order of a finite group |G| and the number of its distinct cyclic subgroups |C(G)|. In order to provide pertinent context and possibly reveal new novel areas of potential research within the field of research on finite groups, we finally pose and solicit a few open questions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=abstract%20algebra" title="abstract algebra">abstract algebra</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclic%20subgroup" title=" cyclic subgroup"> cyclic subgroup</a>, <a href="https://publications.waset.org/abstracts/search?q=finite%20group" title=" finite group"> finite group</a>, <a href="https://publications.waset.org/abstracts/search?q=subgroup" title=" subgroup"> subgroup</a> </p> <a href="https://publications.waset.org/abstracts/153000/characterization-of-number-of-subgroups-of-finite-groups" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153000.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">120</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">121</span> Structural and Electromagnetic Properties of CoFe2O4-ZrO2 Nanocomosites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ravinder%20Reddy%20Butreddy">Ravinder Reddy Butreddy</a>, <a href="https://publications.waset.org/abstracts/search?q=Sadhana%20Katlakunta"> Sadhana Katlakunta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The nanocomposites of CoFe2O4-xZrO2 with different loadings of ZrO2 (x = 0.025, 0.05, 0.075, 0.1 and 1.5) were prepared using ball mill method.

The Green Supply Chain Management (GSCM) is a powerful way to differentiate a company from its competitors and it can greatly influence the plan success. With increased awareness to corporate responsibility and the requirement to meet the terms with environmental policy, GSCM is becoming increasingly important for companies. This paper explains the concept of green supply chain management, the difference between conventional supply chain management and green supply management and how GSCM benefits organizations while at the same time supporting a sustainable environment system.

Photocatalytic reduction of CO<sub>2</sub> to fuel, such as methanol, methane etc. is a promising way to reduce greenhouse gas CO<sub>2</sub> emission. In the present work, Bi<sub>2</sub>S<sub>3</sub>/CdS was synthesized as an effective visible light responsive photocatalyst for CO<sub>2</sub> reduction into methanol. The Bi<sub>2</sub>S<sub>3</sub>/CdS photocatalyst was prepared by hydrothermal reaction. The catalyst was characterized by X-ray diffraction (XRD) instrument. The photocatalytic activity of the catalyst has been investigated for methanol production as a function of time. Gas chromatograph flame ionization detector (GC-FID) was employed to analyze the product. The yield of methanol was found to increase with higher CdS concentration in Bi<sub>2</sub>S<sub>3</sub>/CdS and the maximum yield was obtained for 45 wt% of Bi<sub>2</sub>S<sub>3</sub>/CdS under visible light irradiation was 20 <em>μ</em>mole/g. The result establishes that Bi<sub>2</sub>S<sub>3</sub>/CdS is favorable catalyst to reduce CO<sub>2</sub> to methanol. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=photocatalyst" title="photocatalyst">photocatalyst</a>, <a href="https://publications.waset.org/abstracts/search?q=CO2%20reduction" title=" CO2 reduction"> CO2 reduction</a>, <a href="https://publications.waset.org/abstracts/search?q=methanol" title=" methanol"> methanol</a>, <a href="https://publications.waset.org/abstracts/search?q=visible%20light" title=" visible light"> visible light</a>, <a href="https://publications.waset.org/abstracts/search?q=XRD" title=" XRD"> XRD</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-FID" title=" GC-FID"> GC-FID</a> </p> <a href="https://publications.waset.org/abstracts/43005/preparation-and-characterization-of-photocatalyst-for-the-conversion-of-carbon-dioxide-to-methanol" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43005.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">501</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">117</span> Effective Texture Features for Segmented Mammogram Images Based on Multi-Region of Interest Segmentation Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ramayanam%20Suresh">Ramayanam Suresh</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20Nagaraja%20Rao"> A.

This work suggests a novel approach to increase the precision of thyroid nodule identification by combining machine learning and deep learning. The new approach first extracts information from the ultrasound pictures using a deep learning method known as a convolutional autoencoder. A support vector machine, a type of machine learning model, is then trained using these features. With an accuracy of 92.52%, the support vector machine can differentiate between benign and malignant nodules.

Successes with AI in medical imaging interpretation and clinical decision support are paving the way for its incorporation into routine healthcare delivery. While there has been a focus on the development of ethical principles to guide its application in healthcare, challenges of this application go beyond what ethics principles can address thus requiring robust governance frameworks. Also, while ethical challenges of medical artificial intelligence are being discussed, the ethics of deploying AI in lower-income countries receive less attention than in other developed economies. This creates an imperative not only for sound ethical guidelines but also for robust governance frameworks to regulate AI in medicine around the world.

The ZnO/MPS nanocomposite was irradiated with gamma rays of doses 30, 60, and 90 kGy and dose-rate of irradiation was 0.15 kGy/hour. Irradiated samples are characterized with FE-SEM, FT-IR, UV-vis, and Photoluminescence (PL) spectrometers. SEM pictures showed that morphology changed from spherical to flake like morphology. UV-vis analysis showed that the band gap increased with increase of gamma ray irradiation dose. This enhancement of the band gap is assigned to the depletion of oxygen vacancies with irradiation. The intensity of PL peak decreased gradually with increase of gamma ray irradiation dose. The decrease in PL intensity is attributed to the decrease of oxygen vacancies at the interface due to poor interface and improper passivation between ZnO/MPS. <p
