The experiences of AIDS orphans living in a township
D van Rooyen, S Frood, E Ricks
Health SA Gesondheid , 2012,
Abstract: An overwhelming challenge to health-care professionals today, is the rendering of care services to AIDS orphans. This article is based on a study that explored and described the lived experiences of AIDS orphans in a township in order to understand their ‘life world’ as AIDS orphans. A further purpose was to provide information to primary health-care nurses (PHCNs), related professionals and partners involved in the care of these children, so that they could plan a care response to meet the orphans’ unique needs. A qualitative research design that used an explorative, descriptive, contextual and phenomenological strategy of inquiry was employed. Data were collected by means of in-depth interviews from a purposively selected sample, and were analysed according to the steps of qualitative data analysis proposed by Tesch (Creswell 1994). Guba’s model was used to ensure the trustworthiness of the qualitative data. Two main themes and their sub-themes were identified. The first theme was that children experience devastating changes in their life circumstances when they become AIDS orphans. The second theme highlighted how the participants rediscovered hope to persevere. Recommendations directed at nursing practice, education and research, were made based upon the findings.

Opsomming ‘n Uitdaging wat professionele gesondheidswerkers huidiglik oorweldig, is dienslewering aan VIGS weeskinders. Die doel van die studie was om die geleefde ervaring van kinders wat in dorpsgebiede woon en VIGS weeskinders geword het, te verken en te beskryf ten einde hul leefwêreld te verstaan. Hierdie inligting kan deur Primêre Gesondheidsorg Verpleegkundiges (PVGs), verwante beroepslui en vennote betrokke by die versorging van hierdie kinders, gebruik word as basis om versorging te beplan wat in die kinders se unieke behoeftes sal voorsien. ‘n Kwalitatiewe navorsingsontwerp met verkennende, beskrywende, kontekstuele en fenomologiese strategie van ondersoek, is gebruik. Data is versamel deur middel van in-diepte onderhoude met ‘n doelbewus geselekteerde steekproef. Data is geanaliseer ooreenkomstig die stappe van kwalitatiewe data analise volgens Tesch (in Creswell 1994). Guba se model was gebruik om die betroubaarheid van data te bepaal. Twee hooftemas en hul subtemas is ge dentifiseer. Die eerste tema was dat kinders dramatiese veranderinge in hulle lewensomstandighede ervaar wanneer hulle VIGS weeskinders word. Die tweede tema wat na vore gekom het, was hoe die deelnemers die hoop om voort te gaan met die lewe, herontdek het. Aanbevelings, gebaseer op die bevindinge, is gemaak
Study of the Structural and Electrical Properties of Cr-Doped BiFeO3 Ceramic  [PDF]
S. S. Arafat, S. Ibrahim
Materials Sciences and Applications (MSA) , 2017, DOI: 10.4236/msa.2017.810051
Abstract: Multiferroic BiFe1-xCrxO3 (x = 0.2 and 0.4) ceramics were synthesized in a single phase. The effects of Cr3+ substitution on the crystal structure, dielectric permittivity and leakage current were investigated. Preliminary X-ray structural studies revealed that the samples had a rhombohedral perovskite crystal structure. The dielectric constant ε' significantly increased while the dielectric loss tanδ was substantially decreased with the increase in Cr3+ substitution. The temperature effect on the dielectric properties exhibited an anomaly corresponding to magneto-electric coupling in the samples and was shifted to lower temperatures with the increase in Cr3+ substitution. The leakage current density also reduced in magnitude with the increase in the Cr3+ substitution.

S. S. Sandhya, S. Somasundaram, S. Anusa
Applied Mathematics (AM) , 2015, DOI: 10.4236/am.2015.66086
Abstract: Let \"\" be an injective function. For a vertex labeling f, the induced edge labeling \"\" is defined by, \"\" or \"\"; then, the edge labels are distinct and are from \"\". Then f is called a root square mean labeling of G. In this paper, we prove root square mean labeling of some degree splitting graphs.
A Parameter Estimation Model of G-CSF: Mathematical Model of Cyclical Neutropenia  [PDF]
S. Balamuralitharan, S. Rajasekaran
American Journal of Computational Mathematics (AJCM) , 2012, DOI: 10.4236/ajcm.2012.21002
Abstract: We investigate the FFT (Fast Fourier Transform) model and G-CSF (granulocyte colony-stimulating factor) treatment of CN (Cyclical Neutropenia). We collect grey collies and normal dog’s data from CN and analyze the G-CSF treatment. The model develops the dynamics of circulating blood cells before and after the G-CSF treatment. This is quite natural and useful for the collection of laboratory data for investigation. The proposed interventions are practical. This reduces the quantity of G-CSF required for potential maintenance. This model gives us good result in treatment. The changes would be practical and reduce the risk side as well as the cost of treatment in G-CSF.

Fuzzy Based Intelligent Monitoring of Critical Lines in the Restructured Power Market  [PDF]
S. Rajasekaran, S. Sathiyamoorthy
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.79191
Abstract: Restructured electric market environment allows the power wheeling transactions between the power producers and customers to meet the growing load demand. This will lead to the possible of congestion in the transmission lines. The possible contingencies of power components further worsen the scenario. This paper describes the methodology for the identification of critical transmission line by computing the real power and reactive power performance indices. It also demonstrates the importance of fuzzy logic technique used to rank the transmission lines according to the severity and demonstrated on IEEE-30 bus system.
Error Correction Circuit for Single-Event Hardening of Delay Locked Loops  [PDF]
S. Balaji, S. Ramasamy
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.79210
Abstract: In scaled CMOS processes, the single-event effects generate missing output pulses in Delay-Locked Loop (DLL). Due to its effective sequence detection of the missing pulses in the proposed Error Correction Circuit (ECC) and its portability to be applied to any DLL type, the ECC mitigates the impact of single-event effects and completes its operation with less design complexity without any concern about losing the information. The ECC has been implemented in 180 nm CMOS process and measured the accuracy of mitigation on simulations at LETs up to 100 MeV-cm2/mg. The robustness and portability of the mitigation technique are validated through the results obtained by implementing proposed ECC in XilinxArtix 7 FPGA.
High Frequency Charging Techniques—Grid Connected Power Generation Using Switched Reluctance Generator  [PDF]
S. Sridharan, S. Sudha
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.714352
Abstract: Power generation becomes the need of developed, developing and under developed countries to meet their increasing power requirements. When affordability increases their requirement of power increases, this happens when increased per capita consumption. The existing power scenario states that highest power is produced using firing of coals called thermal energy. A high efficiency Switched Reluctance Generator (SRG) based high frequency switching scheme to enhance the output for grid connectivity is designed, fabricated and evaluated. This proposed method generates the output for the low wind speed. It provides output at low speed because of multi-level DC-DC converter and storage system. It is an efficient solution for low wind power generation. The real time readings and results are discussed.
