HIV/AIDS and men : a critical examination of tensions and challenges in establishing a support group for men

The HIVI AIDS pandemic has introduced significant challenges to health care professionals, specifically the appropriate means of supporting those living with the virus. Little research, however, has critically investigated the difficulties involved in the creation of community interventions in this area. In addition, few men's only HIV/AIDS support groups exist and a relatively modest amount of literature surrounds the subject. This thesis, aims to investigate the struggles and tensions involved in the formation of men's only HIV I AIDS support groups. Three knowledgeable practitioners in the field were interviewed, using semi-structured interview schedules, regarding their experience and knowledge of the complexities faced by those forming a support group of this nature. Supplementary data was also drawn from the authors attempt's to start a support group for men living with HIVI AIDS, based on the principles of Participatory Action Research. The data was examined using thematic analysis. Results from the study indicate that a number of areas may influence or hamper the progress of such groups. Factors surrounding attendance, needs assessment, gatekeepers, the role of masculinity, denial and stigma around HIV/AIDS, as well as unemployment and poverty, all played a role in the ability of a group to sustain itself The dynamics of power and politics inherent in many of these areas, divided broadly into individual, interpersonal, environmental and socio-political are discussed. Critical theory is used to allow for a layered and contextual understanding of the numerous challenges faced by such a project within South Africa. The findings suggest that though there are significant challenges posed in such an intervention, reflexivity, informed preparation and an awareness of power, may all allow for a sustainable group process and thus limit the influence of the intricacies raised.
Assessing the Wind Energy for Rural Areas of Vietnam

This study assesses the wind energy potential of a Bac-Lieu wind farm. The daily wind speed data using in this study was collected over a period of five years between 2006 and 2010. The designed wind farm capacity was 99 MW with 60 individual units of 1.65 MW Vestas wind turbines. The wind energy potential and wind farm economic analysis were carried out by WAsP 10.0 and RETScreen International software, respectively. The results showed that at 80 m height and 0.03 m roughness length, the mean wind speed and wind density were 7.2 m/s and 379 W/m 2 , respectively. The most wind energy came from East, Northeast, and North-Northeast directions. The wind farm produces 332.100 GWh/year, and prevents 232,470 tons/year of CO 2 equivalent greenhouse gas (GHG) from entering the local atmosphere. In the economic analysis, the wind farm has total initial cost of $198,100,000 USD. Total annual savings and profit is about $39,558,901 USD. The simple payback and equity payback of the wind farm are around 5.2 years and 2.1 years, respectively. The wind farm being assessed is located at Vinh-Trach-Dong, Bac-Lieu, Vietnam.
Reliability of the Electromechanical Delay Components Assessment during the Relaxation Phase

The study aimed to assess by an electromyographic (EMG), mechanomyographic (MMG), and force-combined approach the electrochemical and mechanical components of the overall electromechanical delay during relaxation (R-EMD). Reliability of the measurements was also assessed. To this purpose, supramaximal tetanic stimulations (50 Hz) were delivered to the gastrocnemius medialis muscle of 17 participants. During stimulations, the EMG, MMG, and force signals were detected, and the time lag between EMG cessation and the beginning of force decay ( EMG-F, as temporal indicators of the electrochemical events) and from the initial force decrease to the largest negative peak of MMG signal during relaxation ( F-MMG, as temporal indicators of the mechanical events) was calculated, together with overall R-EMD duration (from EMG cessation to the largest MMG negative peak during relaxation). Peak force (pF), half relaxation time (HRT), and MMG peak-to-peak during the relaxation phase (R-MMG p-p) were also calculated. Test-retest reliability was assessed by Intraclass Correlation Coefficient (ICC). With a total R-EMD duration of 96.9 ± 1.9 ms, EMG-F contributed for about 24% (23.4 ± 2.7 ms) while F-MMG for about 76% (73.5 ± 3.2 ms). Reliability of the measurements was high for all variables. Our findings show that the main contributor to R-EMD is represented by the mechanical components (series elastic components and muscle fibres behaviour), with a high reliability level for this type of approach.
Scalar Wave Diffraction by Perfectly Soft Thin Circular Cylinder of Finite Length; Analytical Regularization Method

A new mathematically rigorous and numerically effective method for solving the boundary value problem of scalar wave diffraction by an infinitely thin circular cylindrical screen of finite length is proposed. The method is based on the combination of the Orthogonal Polynomials Approach, and on the ideas of the methods of analytical regularization. As a result of the suggested regularization procedure, the initial boundary value problem is equivalently reduced to the infinite system of the linear algebraic equations of the second kind, i.e. to an equation of the type (I + H)x = b in the space \ell 2 of square summable sequences. This equation can be solved numerically by means of truncation with, in principle, any required accuracy.
STOCK MARKET AND MACROECONOMIC VARIABLES: EVIDENCES FROM LITHUANIA

The stock market has been historically viewed as a reliable instrument to indicate economic processes. However, contemporary papers reveal the controversy of the issue. A clear understanding of stock market determinants is vital for investors, regulators, and academic researchers. Therefore, future researches are required to further explore this issue. The present paper analyzes relationships between a group of macroeconomic variables and the Lithuanian stock market index, i.e. OMX Vilnius index. The objective of this paper is to investigate whether stock prices may serve as a leading indicator for macroeconomic variables in Lithuanian economy or a group of macroeconomic variables may serve as a leading indicator for stock returns in Lithuania. Granger causality tests have been employed to estimate the relationship between the OMXV index and 40 macroeconomic variables depicting the health of Lithuanian economy from December 1999 to March 2008. The research reveals that some macroeconomic variables (e.g., GDP deflator, net export, foreign direct investment, etc.) lead Lithuanian stock market returns, some macroeconomic variables (e.g., GDP, material investment, construction volume index, etc.) are led by the OMXV index and, finally, some macroeconomic indices (e.g., money supply, payment balance, etc.) and the stock market returns Granger-cause each other.
Failure of an Inconel 718 Die used in Production of Hot Copper Direct Extrusion

Steel dies used in hot extrusion of copper failed after several extrusion cycles (2-5 tons of extruded material). In the extrusion process the die is subjected to high temperatures and stresses the failure mechanisms was plastic deformation. Industry considers new die materials, such as Inconel 718. In this research it was shown that during production using an Inconel 718 die one can extrude 8 times more material (approx. 40 tons). After the extrusion of 40 tons of copper small cracks and plastic deformation on die aperture are seen. The die was discarded and used to investigate die failure mechanisms. By using different investigation methods (optic and scanning electron microscopy, hardness and microhardness tests) microstructure changes were observed. This research was done in the collaboration of Politehnica University of Bucharest, Romania and S.C. LAROMET S.A. (a manufacturer of copper and copper alloys).
Host habitat location mediated by olfactory stimuli in anaphes iole (hymenoptera: mymaridae), an egg parasitoid of lygus hesperus (hemiptera: miridae)

Host Habitat Location Mediated by Olfactory Stimuli in Anaphes iole (Hymenoptera: Mymaridae), an Egg Parasitoid of Lygus hesperus (Hemiptera: Miridae). (December 2003) Veronica Manrique, B.S., University of Buenos Aires Co-Chairs of Advisory Committee: Dr. J. S. Bernal Dr. W. A. Jones Lygus hesperus is an important pest on different crops including cotton and alfalfa in the western U.S. Anaphes iole is a common parasitoid of Lygus spp. eggs in the U.S. and has potential as a biological control agent against L. hesperus in different crops. Its foraging behavior has been studied to a limited extent, but it is unknown whether A. iole females rely on plant volatiles to locate host habitats. L. hesperus feeding and oviposition are known to induce emission of plant volatiles in cotton and maize, but no studies have addressed the role of plant volatiles in the host searching behavior of A. iole. The objectives of this study were to evaluate the attraction of A. iole females toward volatiles derived from L. hesperus habitats and flight response of A. iole females toward cotton plants harboring L. hesperus eggs or treated with methyl jasmonate. Results from olfactometry bioassays showed that female wasps were attracted to odors emanating from different plant-L. hesperus complexes and from adult L. hesperus, while plants damaged by non-hosts or mechanically-damaged were not attractive. These findings suggested that A. iole females use specific plant volatiles released following L. hesperus
Transformations Accompanying a Shift from Surface to Drip Irrigation in the Cànyoles Watershed , Valencia , Spain

Drip irrigation is widely promoted in Spain to increase agricultural production and to save water. In the Cànyoles watershed, Valencia, we analysed the consequences of change from surface irrigation to drip irrigation over the past 25 years. There were a number of transformations resulting from, or accelerated by, this change including the 1) intensification of well construction causing a redistribution in access to groundwater, water shortages and a lowering of the groundwater table; 2) expansion of irrigation into former rain-dependent uphill areas resulting in increased water use; 3) shift to highervalue monoculture fruit crops, but with associated higher crop water requirements; 4) increased electrical energy consumption and higher costs due to groundwater pumping; and 5) loss of cultural heritage as wells have replaced traditional surface irrigation infrastructure that originated in the Middle Ages. Consequently, the authors argue that transitioning from surface irrigation to drip irrigation should critically look beyond the obvious short-term benefits that are intended by the introduction of the technology, and consider possible unforeseen side effects, that may have serious long-term impacts on the environment and the community.
ON-SITE DERATING OF IN-SERVICE POWER DISTRIBUTION TRANSFORMERS SUPPLYING NOLINEAR LOADS

The paper analyzes the intentional reduction of the maximum load capacity (derating) for the in-service dry-type three-phase power distribution transformers that operate under nonsinusoidal steady state condition. A real-time, less intrusive and efficient derating procedure was developed and implemented in accordance with the international standards recommendations. Due to a flexible developed software package, the proposed computation method only requires the nameplate data of the investigated transformer and the harmonic spectrum of the load current measured at transformer secondary (low-voltage) windings. Thus, the additional harmonic losses within the transformer and their corresponding maximal permissible nonsinusoidal current are continuously computed according to the characteristics of load changes. In order to validate the results, the procedure was tested on a distribution transformer that supplies heavy nonlinear loads of an industrial facility.
Theoretical perspectives on resource tax design

The importance and complexity of petroleum and hard minerals operations is matched by the importance and complexity of finding effective ways to tax them. Many of these challenges arise in other activities too (exhaustibility of deposits being the main exception), but they take such extreme form in relation to resources as to have led to a proliferation of creative instruments and analytical methods. This paper reviews the challenges for tax policy in dealing with the resource sector, the principal instruments used, and some of the central design issues.
STUDY OF LOW-CYCLE FATIGUE IN HEAT-TREATED Al-Mg ALLOYS

The AA5182 Al-Mg alloy is used in applications where high formability and strength are required like container ends, can stocks, reinforcement members and automotive parts. With convenient heat treatments the alloy strength increases and it can be used in aerospace applications. In the present research Al-Mg aluminum beverage can tabs were heat treated within a temperature range between 170oC and 450oC beginning with solubility and then aging treatment. The tabs were tested under low-cycle fatigue conditions. The fatigue strength measured by the number of loading cycles increased in the first two hours of exposure to the aging treatment at any temperature. The maximum resistance was reached at 2.5 hours. After this time it dropped in all treatments except for the 270oC treatment, where it decreased gradually. The fatigue strength increment could not be defined since the geometry of the tab affected the type of fracture and the number well of cycles. In the microstructure, the formation of precipitates at low temperature (aging 170 oC and 270 oC) caused a low fatigue resistance in the material. However at high temperatures (370oC) the treatment facilitated precipitates dissolution reinforcing the aluminum matrix and making it more resistant.
System approach to the hygienic standards of xenobiotics in different environments

Based on the own experimental data and comprehensive analysis of national toxicometric indicators and MPC of 330 chemicals in different media (working area, atmospheric air and water reservoirs), as well as 265 standards used in the US and the EU, a systematic approach was designed and implemented with the purpose of substantiating the chemicals hygienic standards in different media. It takes into consideration the parameters of toxicity and cumulative properties of standardized substances which are manifested integrally by the reliability standard value, determined by the ratio of LC50 (LD50)/MPC wz , which correlates with the corresponding relations of foreign standards. At the same time, MPC wz plays an important part in the parameters of the system creation. Implementation of the methodological guide developed by the authors and approved by the Ministry of Public Health of Ukraine provided the opportunity to significantly reduce uncertainties in the process of hygienic standardization, improving the reliability of newly developed standards and correction of existing standards on the basis of newly accumulated experimental and clinical data. Further development of systematic approach to the hygienic standards will more successfully solve challenges of hygiene and quantitative toxicology, as the assessment of acceptable risk, the combined effects of chemical substances, the substantiation of regional, emergency standards, integrated regulatory support of chemical safety of the workers and the population as whole.
Modulation of autophagy enhances the apoptotic cell death in human T lymphoma cells treated with Anthocyanin

In the present study, the effect of modulation of autophagy induced by anthocyanin on cell death of Human T lymphoma cells (Jurkat) was studied. Anthocyanin was abstracted from dry petals of Hibiscus sabdariffa, aquous solution of anthocyanin was added to cells at different concentrations then cell viability was determined by trypan blue exclusion method. Autophagy induced by anthocyanin was inhibited by 5 mM NH4CL which halts lysosomal enzymes and accordingly preventing autolysosomes formation. On the other hand, Autophagy was enhanced by glucose starvation. In both experiments of autophagy inhibition and enhancement, cell viability was studied to investigate the effect of autophagy modulation on cell viability. The results of this work revealed that both inhibition and enhancement of autophagy induced by anthocyanin lead to massive cell death. Immuno-detection of active caspase 3, one of the major hallmark of apoptotic cell death revealed remarkable increase of active caspse3 upon autophagy inhibition or enhancement. In conclusion, modulation of autophagy induced by anthocyanin lead to increasing of apoptotic cell death.
Performance and Efforts Regarding Usage of Mobile Phones among Farmers for Agriculture knowledge

Nowadays everyone is using mobile phone for connect with each other’s and get information about different issues and updates around the world. However, mobile phones have also played an important role in the development of agriculture and make it easy for farmers to communicate with buyers and sellers to sell their goods in reasonable price. The study was conducted in Sindh province of Pakistan where ten districts were selected and 1500 farmers randomly were selected for interview. While 150 farmers were selected from these ten districts according to the list provided by Agriculture Department Government of Sindh and Sindh Irrigation & Drainage Authority (SIDA). Study showed that most of the farmers possessed their own mobile phone and more than half around 64% of the respondents directly call the buyers and negotiated to sell their goods. Moreover, 44.9% of the respondents neither agree nor disagree regarding mobile phone expanding their market information and 40.3% of the respondents take efforts and understand that mobile phones has improved their skills to communicate with buyers in market. However, due to lack of infrastructure still farmers are facing many problems in their working areas and have no proper information about pesticide use and weather updates in their agriculture areas. Government and non-governmental organizations should improve their skills and knowledge about agriculture product where farmers can increase their product in future.
TeXTracT: a Web-based Tool for Building NLP-enabled Applications

Over the last few years, the software industry has showed an increasing interest for applications with Natural Language Processing (NLP) capabilities. Several cloud-based solutions have emerged with the purpose of simplifying and streamlining the integration of NLP techniques via Web services. These NLP techniques cover tasks such as language detection, entity recognition, sentiment analysis, classification, among others. However, the services provided are not always as extensible and configurable as a developer may want, preventing their use in industry-grade developments and limiting their adoption in specialized domains (e.g., for analyzing technical documentation). In this context, we have developed a tool called TeXTracT that is designed to be composable, extensible, configurable and accessible. In our tool, NLP techniques can be accessed independently and orchestrated in a pipeline via RESTful Web services. Moreover, the architecture supports the setup and deployment of NLP techniques on demand. The NLP infrastructure is built upon the UIMA framework, which defines communication protocols and uniform service interfaces for text analysis modules. TeXTracT has been evaluated in two case-studies to assess its pros and cons.
Spatial and temporal variability in nutrients and carbon uptake during 2004 and 2005 in the eastern equatorial Pacific Ocean

Abstract. The eastern equatorial Pacific plays a~great role in the global carbon budget due to its enhanced biological productivity linked to the equatorial upwelling. However, as confirmed by the Equatorial Biocomplexity cruises in 2004 and 2005, nutrient upwelling supply varies strongly, partly due to the tropical instability waves (TIWs). The aim of this study was to examine patterns of spatial and temporal variability in the biological uptake of NO3, Si(OH)4 and carbon in this region, and to evaluate the role of biological and physical interactions controlling this variability over seasonal and intraseasonal time scales. Here, high resolution Pacific ROMS–CoSiNE (Regional Ocean Modeling System–Carbon, Silicon, Nitrogen Ecosystem) model results were evaluated with in situ and remote sensing data. The results of model–data comparison revealed a good agreement in domain-average hydrographic and biological rate estimates, and patterns of spatio-temporal variability in primary productivity. We confirmed that TIWs have the potential to enhance phytoplankton biomass through an increased supply of nutrients and elevated local and instantaneous phytoplankton nutrient uptake as opposed to only advecting biomass. Furthermore, we concluded that initial biological conditions (e.g., zooplankton biomass) may play an important additional constraint on biological responses, in particular of large phytoplankton such as diatoms, to TIW-induced perturbations in the physical and biogeochemical fields and fluxes. In order to fully resolve the complexity of biological and physical interactions in the eastern equatorial Pacific, we recommended improving CoSiNE and other models by introducing more phytoplankton groups, variable Redfield and carbon to chlorophyll ratios, as well as resolving the Fe–Si co-limitation of phytoplankton growth.
Natural convection of alumina-distilled water nanofluid in cylindrical enclosure: an experimental study

Temperature distribution of nanofluids has been investigated experimentally using thermography method and it is shown that suspended small amount of Al 2O3 nanoparticles into distilled water were capable of lowering surface temperature of cylindrical enclosure. Also, for low concentration of nanoparticle, homogenising is the most preferable equipment used to produce homogenous and stable nanofluid. However, deterioration result was observed at high volume
Electrochemical Sandwich Immunoassay for the Ultrasensitive Detection of Human MUC1 Cancer Biomarker

A new electrochemical sandwich immunoassay for the ultrasensitive detection of human MUC1 cancer biomarker using protein G-functionalized magnetic beads (MBs) and graphite-based screen-printed electrodes (SPEs) was developed. Magnetic beads were employed as the platforms for the immobilization and immunoreaction process. A pair of primary and secondary antibodies was used to capture the MUC1 protein. After labeling with a third antibody conjugated with horseradish peroxidase (HRP), the resulting conjugate was trapped at the surface of the graphite-based SPEs and MUC1 determination was carried out by differential pulse voltammetry (DPV) at 0.4 V upon H2O2 addition using acetaminophen (APAP) as the redox mediator. A linear relationship was obtained for the detection of human MUC1 over a range of 0–25 ppb with the lowest detection limit of 1.34 ppb when HRP was applied as a label. Preliminary experiments were performed using disposable electrochemical sensors in order to optimize some parameters (i.e., incubation times, concentrations, and blocking agent).
