An Efficient Architecture in Next Generation Wireless Networks
Anjali Rasal,Dr. S. D. Lokhande
International Journal of Engineering Science and Technology , 2010,
Abstract: Next-Generation wireless networks are proposed to achieve the goal of ubiquitous wireless networking by utilizing heterogeneous networks. The performance of Location management scheme directly affects the overall performance of NGWN at large. This affect significantly impacts on the signalling traffic in terms of the database’s waiting time, query and update response time, processing power, bandwidth requirements etc. in the global roaming. Several architectures have been proposed to reduce such traffic. We have analyzed the impactof different system parameters with different architectures, one is multi-tier HLR and another is WING architecture. The performance of these architectures is analyzed with parameters such as location management cost, paging cost, query response time etc. The result of this work shows that WING architecture enhances the location management scheme than MHLR architecture during heterogeneous system roaming process. Thus in global roaming WING architecture can improve the network performance significantly in terms of signalling traffic.

Abstract: 1The term “street children” has been used inter changeably with “children in especially difficult circumstances” in the remaining document. This paper discusses the findings of a research project which is an exploratory cum descriptive study [1] that aims to describe and examine the state and nature of the quality of life of street children accommodated at an unorganised colony in the city of Delhi. It provides a social profile of children and their families, and exploring the needs and aspirations of these children living in especially difficult circumstances. A non-probability sample of 100 street children in the age group of 5-16 years was randomly selected guided by their availability. An interview schedule was constructed and administered to gather data. The statistical analyses comprised frequencies and percentages on all the sections of the interview schedule. Thematic content analysis was used to analyse data from open-ended questions and observations. Case studies were supportive in giving an insight into the lives of children living in especially difficult circumstances. Findings suggest that the quality of life of the participants in this study was depressed due to a lack of access or substandard educational and medical facilities, or absence of emotional support from their poverty stricken families. The existing limited programmes by the government or the civil society for the welfare of street children are lacking in their focus and do not include the voices and needs of the beneficiaries. Although service providers expressed sympathy for street children, many regarded them as deviants, delinquents, future criminals, and a public nuisance. Based on the findings, it has been suggested that the street child phenomenon necessitates a partnership between governmental and non-governmental organizations to provide for policy and legislation, funding and resources to translate programs into concrete plans of action. It has further been argued that such an approach should extend to children using their resourcefulness and creativity, and show that they can be significant in development interventions. Children illustrate both the need for participatory approaches and the problems that arise when perceptions of participants conflict with those of experts.

Indian Journal of Orthopaedics , 2006,
Abstract: Background : Though described long back, there has been a renewed interest towards Ponseti method of conservative treatment of clubfoot recently. Methods : Forty children with idiopathic clubfeet were treated by Ponseti technique. The median age at presentation was 9 days. Twenty-six children with bilateral and 12 children with unilateral clubfeet were graded by the Pirani method at the commencement of treatment and then at the final follow-up. Feet were graded as excellent if the Pirani score was zero, fair, if the sum of mid-foot and hind-foot score was one or less and poor, if the score was more than one. Thirty four children need a heel cord tenotomy and all children received conventional ankle-foot orthosis (AFO) and foot-abduction orthosis (FAO) to maintain correction. Results : Twenty-eight children had excellent correction, four had a fair outcome and eight cases had relapse in their deformity. Poor splint compliance and fitting along with incomplete correction of the deformity were identified as the chief causes leading to a poor result. Conclusion : A strict protocol and parent education can improve the outcome for all cases with the Ponseti technique. Key-words: Clubfoot; Congenital talipes equinovarus; Ponseti technique.

Amrita Talapatra, Anjali Srivastava
Journal of Environmental Protection (JEP) , 2011, DOI: 10.4236/jep.2011.21003
Abstract: Different aspects of Volatile Organic Compounds (VOCs) are being investigated in details by different research groups in Indian institutes. The spectrum covers measuring technologies, source apportionment and variability studies, all these are in due process of preparing a guideline for the sustainable development in terms of industrial, infrastructural as well as overall growth of the country. Both the outdoor and indoor air quality has significant impact on human health. With special concentration on BTEX and HAPs, the health related investigations are conducted as part of interdisciplinary studies of environmental science. Newer technologies to remove VOCs under specific industrial and practical conditions are getting emerged as a comparatively new era. It addresses fields like adsorption, condensation, pervaporation, biodegradation and catalytic combustion. Besides, different kinds of biofilters have drawn significant attention nowadays. The final selection of appropriate technology depends on type and concentrations of VOCs, extent of separation required and cost involved. All these technologies are although well studied, but could not be adopted for regular commercial usage till date. There is scope to explore new horizons as well as regular monitoring on the introduced pathways to limit VOC emission in the ambient air. This review aims at a concise discussion on all the areas that come under the umbrella of non-methane VOC technologies.

Anjali Goel, Neetu Rani
Open Journal of Inorganic Chemistry (OJIC) , 2012, DOI: 10.4236/ojic.2012.23010
Abstract: Commonly transition metal nano particle are synthesized by physical, chemical or electrochemical methods. In the present work colloidal iridium nanoparticles were synthesized by chemical oxidation method with different surfactants like poly vinyl pyrrolidone (PVP), poly vinyl alcohol (PVA) and poly oxyethylene lauryl ether (POLE). It was found that shape and size of Ir-nano particles resulted were related to kind of capping agent (surfactant) used. The characterization of the synthesized nano particle has been carried out by UV-vis, X-ray diffraction (XRD), FT-IR, scanning electron microscopy (SEM) and transmission electron microscopic (TEM) techniques. UV-vis and FT-IR confirm the oxidation of IrCl3 into IrO2 while XRD confirms the amorphous nature of the iridium nanoparticles synthesized. The morphology and size of the particle were confirmed by TEM. The average particle size determined by Scherrer equation was about 4.12 nm to 4.23 nm with PVP, 2.74 to 3.36 nm with PVA and 20.41 to 42.25 nm with POLE. Poly oxyethylene lauryl ether particles were not further analyzed because of their large size and less stability. Further particle size was confirmed with TEM, which was 4.5 nm with PVP and 7.0 nm with PVA. The particles are spherical with no agglomeration tendency.

Anjali Malhotra, Sumitra Yadav
World Journal of AIDS (WJA) , 2016, DOI: 10.4236/wja.2016.64020
Abstract: Background: Women diagnosed with HIV/AIDS may transmit the infection to their child during pregnancy. The infection may spread during pregnancy, childbirth, or breastfeeding. However, the risk of mother-to-child transmission of HIV may be reduced by the use of HIV medications known as antiretroviral therapy (ART). Infection with HIV/AIDS is not a contraindication to pregnancy. Some women are unaware they have the disease until they become pregnant. In this case, they should begin antiretroviral therapy as soon as possible [1]. With the appropriate treatment, the risk of mother-to-child infection can be reduced to below 1% [2]. Without treatment, the risk of transmission is 15% - 45% [3]. Objective: The main aim of the study is to appreciate the declining trend of HIV in babies with HIV positive mother by implementation of PPTCT services. Methods: A retrospective study of detection of HIV positive mothers among all the antenatal patients attending OPD and including the patients coming in Emergency services and delivered in Department of Obstetrics and Gynecology at MGMMC & M. Y. Hospital, Indore, Madhya Pradesh (India) from Jan 2006 to Dec 2015 was included in the study. They were screened for HIV status and further management of all HIV positive patients.

Anjali Sharma, Barkha Singhal
Advances in Bioscience and Biotechnology (ABB) , 2019, DOI: 10.4236/abb.2019.103004
Abstract: The phenomenal rise in the demand of biosensors accelerated their rapid development and immersive applications in the myriads of fields. The essential requirement of developing efficient bio-sensing platform is to find stable well organized interfacial architecture that can serve as an excellent matrix for binding and recognizing biomolecules. In this context, the enormous potential has been envisaged in surface layer proteins that represented themselves as most primitive and simplest self-assembled system with repetitive physicochemical properties for the molecular functionalization of surfaces and various interfaces. The prominence of S-layer proteins has been broadened by integrating genetic engineering approaches for the fine tuning of functional groups and protein domains in geometrically well-defined manner. The efficient and stable binding of various nanomaterials with S-layers in regular arrays has led to paradigmatic shift in their nano-biotechnological sensing applications. More recently, functional S-layer supported lipid membranes have been generated through covalent binding of lipid molecules either with native or recombinant S-layer proteins at nano-scale dimensions serving as “proof of concept” for the development of bio-sensing platform. Thus, in the light of benefits conferred by surface layer proteins for the development of highly efficient biosensors, an exciting path has been opened for broadening their translational applications in drug delivery, disease diagnosis, vaccines development, lab-on-chip devices etc. Therefore, this review intends to describe about the importance of surface layer proteins in the development of biosensors.

Open Journal of Medical Microbiology (OJMM) , 2017, DOI: 10.4236/ojmm.2017.73005
Abstract: Purpose: Bacterial biofilm develop on the surfaces of urinary catheter and proceed to cause full blown bacterial infections and sepsis. Urinary catheters, infection rates increase with the duration of catheterization at rates of per day with virtually all of those who undergo long-term catheterization becoming infected. Also antibiotics results in the adaptation and development of resistance leading to treatment failure, prolonged hospitalization, increased costs of care, and increased mortality. Methods: In the present study total 200 used urinary catheters were studied from the different hospitals of Amravati city in 2015-2016. Different bacterial uropathogens were isolated by conventional method and biofilm formation was studied by tissue culture plate (TCP). Antibiotic sensitivity was performed by disc diffusion method. Minimum inhibitory concentration (MIC) and Minimum biofilm eradicating concentration (MBEC) of triclosan was determined by TCP. Results: Out of total samples 93% are contaminated. Around 59% urinary catheters contain mixed consortia. Pseudomonas aeruginosa was found to be the strong biofilm forming and multidrug resistant organism. The most effective drug over seven bacteria isolates were chloramphenicol. Triclosan was used to test against the strong and moderate biofilm forming isolates the MIC of triclosan ranged between 1.5 and 1000 μg/ml and MBEC was between 800 and 3200 μg/ml Conclusions: From the study it was concluded that female are more prone to be infected with catheter associated infection. Pseudomonas aeruginosa was found to be deadly caused of infection, as it is highly resistant to antibiotics. Also triclosan showed effective result on the bacterial uropathogens.
GASD: An aid for stone-deaf person
Rasal Suyog M.,Dahale Ketaki P.
International Journal of Engineering Science and Technology , 2012,
Abstract: About 120 million people, around the world have some or more degree of hearing loss. Out of these 20% of people are profoundly deaf or stone deaf that is they hear NO sound from the outside world. Three in every 1000 children are born with a hearing loss or lose some hearing before learning to speak. Digital hearing aids are not working for residual hearing persons. Corrective surgery and hearing aids can improve some forms of deafness but usually not profound deafness caused by inner ear damage. In this work it has been tried toimplement a guiding system for stone deaf persons. We have defined the generic electronic circuit imposing PIC microcontroller as that allowing the assembly of several hearing aids models based on the some electronic components. This guiding aid is very useful forstone-deaf person, who can respond the sound himself only. The device also includes RF modules. When particular frequency sound waves coming from different directions, are sensed by respective sensors, the respective sensor produces electric signals so that the respective vibrating device generates vibration. In this way, deaf person is capable to respond sound sources.
