Abstract: We describe factors determining retention and survival among HIV-infected children and adolescents engaged in two health care delivery models in Kampala, Uganda: one is a community home-based care (CHBC) and the other is a facility-based family-centred approach (FBFCA). This retrospective cohort study reviewed records from children aged from 0 to 18 years engaged in the two models from 2003 to 2010 focussing on retention/loss to follow-up, mortality, use of antiretroviral therapy (ART), and clinical characteristics. Kaplan Meier survival curves with log rank tests were used to describe and compare retention and survival. Overall, 1,623 children were included, 90.0% (1460/1623) from the CHBC. Children completed an average of 4.2 years of follow-up (maximum 7.7 years). Median age was 53 (IQR: 11–109) months at enrolment. In the CHBC, retention differed significantly between patients on ART and those not (log-rank test, adjusted, ). Comparing ART patients in both models, there was no significant difference in long-term survival (log-rank test, , adjusted, ), while retention was higher in the CHBC: 94.8% versus 84.7% in the FBFCA (log-rank test, , adjusted ). Irrespective of model of care, children receiving ART had better retention in care and survival. 1. Background Sub-Saharan Africa (SSA) is home to the vast majority of infants, children, and adolescents living with HIV and morbidity and mortality remain high [1–3]. For example, mortality among HIV-infected children has been measured at 4.3% per year in East Africa and 8.3% in West Africa [4, 5]. A recent meta-analysis conducted in SSA reported a higher risk of early death among perinatally infected children [6]. Studies have also shown that substantial proportions of children and adolescents initiate treatment in SSA with advanced disease (46.3%–72.0%) and comorbidities such as tuberculosis (TB) (5.7%–34.0%) and malnutrition (33%–54%) that tend to be associated with early mortality and poor clinical outcomes [7–10]. Significant child mortality can be averted if antiretroviral therapy (ART) is started early [11–14]. However, despite overwhelming evidence demonstrating the benefits of ART, in practice high mortality and poor retention persist among HIV-infected children and adolescents in care in the resource-limited settings of SSA. In addition to scarce resources for programmes for children, the situation is compounded by a combination of factors including late HIV diagnosis, missed opportunities to initiate ART, health care programmes not tailored to the needs of the infected child and their family,
Economically Precise Water Resource Management for Domestic Usage in India  [PDF]
P. Babu, C. Rajasekaran
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.710240
Abstract: In the present years water resource that can be utilized for domestic usage is getting reduced dramatically. In order to have sufficient water for the utilization of future generation, it is our duty to conserve and utilize the available water in a very efficient way. This paper is aimed to help the people to conserve water; it is done with the help of an embedded system that is reconfigurable depending on the number of persons in the family. The system consists of three modules. Each has a different purpose, one module senses the water level present in the tank and intimates the user regarding when the water is needed to be restored. The second module deals with the division of water based on the type of application for which is intended. The third module deals with intimating the municipality regarding the availability of water. All the three modules combine to work in conserving the water; as a result, we can consume nearly 30% per year per head. So this would result in a large amount of conservation of water. Thus the saved water can be reused for several applications.

American Journal of Plant Sciences (AJPS) , 2016, DOI: 10.4236/ajps.2016.77108
Abstract: Cassava is the principal staple root crop, providing a major source of calories for rural and urban households in Luapula province of Zambia. However, the yields on smallholder farms are relatively low largely due to disease infections. The study was therefore conducted to establish farmers’ perceptions, knowledge and management of cassava mosaic disease (CMD), which is one of the major diseases of cassava, and to establish farmers’ preferred traits, constraints and assess sources of cassava cuttings for planting. Focus group discussions (FGD) and structured interviews involving 156 farmers in Mwense, Mansa and Samfya districts were conducted from December 2008 to March 2009. Knowledge of CMD was limited among the respondents. Only 2.4% of the respondents were aware of the disease despite high CMD incidence in farmers’ fields. The majority of the farmers were aware of the importance of insect pests; however, they could not differentiate between damages due to diseases or insect pests. High yield and early bulking traits were highly ranked. Most of the farmers planted local landraces on small-fields (<1 ha). It was evident that a local breeding programme aimed at developing locally adapted disease and pest resistant cassava cultivars was a pressing requirement.

Abstract: Depression is the most common psychiatric condition in Chronic Kidney Disease (CKD), but there are few studies that analyzed this condition in patients in different phases of disease. This article aims to evaluated depression in CKD patients, comparing patients in different phases of disease. Methods: We evaluated 134 patients with CKD submitted to conservative ambulatory treatment, and 36 patients with end-stage renal disease undergoing hemodialysis (HD). To evaluate depression, we used the Beck Depression Inventory (BDI), and the Beck Depression Inventory—SF (BDI-SF), a subscale that allows evaluate only the cognitive aspects of depression. Functional capacity was evaluated using the Karnofsky Performance Scale, and clinical and sociodemographic variables were also investigated. Results: Using BDI, depression was identified in 37.3% of patients in conservative treatment and in 41.6% in HD patients (p > 0.05). This percentage reduced when the BDI-SF was used, to 11.1% in conservative CKD patients and 13.8% in HD patients (p > 0.05). Depression was associated with marital status, professional activity, income, comorbidities and functional capacity. Discussion: We observed high prevalence of depression in patients with CKD undergoing conservative or hemodialysis treatment. Depression was associated with some clinical and sociodemografic variables and with functional capacity.

Journal of Crystallization Process and Technology (JCPT) , 2012, DOI: 10.4236/jcpt.2012.21004
Abstract: In this analysis, the single crystal of L-Proline Succinate (LPS) has been successfully synthesized and the purity of ma- terial has been increased by repeated recrystallization process. Single crystal was grown by adopting the method of growing in a slow evaporation solution using water as solvent at room temperature. The LPS single crystal has been synthesized by taking equimolar quantity of L-Proline and succinic acid, by mixing them thoroughly using deionized water. The prepared concentrated solution was placed in an undisturbed condition, and the solution was inspected regu- larly. The single crystal has been harvested over a period of 1 month. The same crystal was characterized by different techniques for finding its suitability for device fabrications. The grown crystal was characterized by Single crystal XRD, Powder XRD, FTIR, UV-vis-NIR, DTA/TGA and SHG analyses, respectively. The observed results from various char- acterization show the suitability for NLO application. The second harmonic generation of this grown crystal was checked using Kurtz Perry technique which showed positive results. The UV cut-off wavelength and the decomposition temperature of this grown crystal were found to be good when compared with the existing organic crystals.

Journal of Signal and Information Processing (JSIP) , 2013, DOI: 10.4236/jsip.2013.41011

In data mining framework, for proficient data examination recent researchers utilized branch-and-bound methods such as seriation, clustering, and feature selection. Conventional cluster search was completed with diverse partitioning schemes to optimize the cluster pattern. Considering image data, partitioning approaches seems to be computationally complex due to large data size, and uncertainty of number of clusters. Recent work presented a new version of branch and bound model called model selection problem, handles the clustering issues more efficiently. The existing work deployed spatially coherent sampling for generating cluster parameter candidates. But if the problem-specific bounds and/or added heuristics in the data points of the domain area get surmounted, memory overheads, specific model selection, and uncertain data points cause various clustering abnormalities. To overcome the above mentioned issues, we plan to present an Optimal Model-Selection Clustering for image data point analysis in the context of knowledge and data discovery in highly dense data points with more uncertainty. In this work, we are going to analyze the model selection clustering which is first initiated through the process of heuristic training sequences on image data points and appropriates the problem-specific characteristics. Heuristic training sequences will generate and test a set of models to determine whether the model is matched with the characteristics of the problem or not. Through the process of heuristic training sequences, we efficiently perform the model selection criteria. An experimental evaluation is conducted on the proposed model selection clustering for image data point using heuristic approach (MSCHA) with real and synthetic data sets extracted from research repositories (UCI) and performance of the proposed MSCHA is measured in terms of Data point density, Model-Selection Criteria, Cluster validity.

A Novel Asymmetrical Single-Phase Multilevel Inverter Suitable for Hybrid Renewable Energy Sources  [PDF]

Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.76079
Abstract: This paper introduces a novel single-phase asymmetrical multilevel inverter suitable for hybrid renewable energy sources. The proposed inverter consists of two isolated DC sources and six power semiconductor controlled switches. The suggested inverter is capable of generating seven-level output when the input DC voltage is taken in the ratio of 1:2. The higher magnitude DC source is fed from Photo Voltaic (PV) panels, whereas the lower magnitude DC source is fed from Wind Turbine (WT) driven Permanent Magnet DC (PMDC) generator. Both the renewable energy sources are connected to the inverter via two DC-DC boost converters connected in cascade (i.e.one for maximum power point tracking and another for DC-link voltage control). The proposed hybrid renewable energy source inverter is connected to single-phase grid via proper control systems. The complete system is simulated using MATLAB/SIMULINK and the results are presented in detail.

Abstract: Pre-tested, self-administered questionnaires were sent by email to all Fogarty alumni at the MAKCHS (mentors) and each of them was requested to complete and email back the questionnaire. In addition to training level and number of mentors, the questionnaires had open-ended questions covering themes such as; status of mentorship, challenges faced by mentors and strategies to improve and sustain mentorship within MAKCHS. Similarly, open-ended questionnaires were sent and received by email from all graduate students (mentees) registered with the Uganda Society for Health Scientists (USHS). Qualitative data from mentors and mentees was analyzed manually according to the pre-determined themes.Twenty- two out of 100 mentors responded (14 email and 8 hard copy responses). Up to 77% (17/22) of mentors had Master's-level training and only 18% (4/22) had doctorate-level training. About 40% of the mentors had ≥ two mentees while 27% had none. Qualitative results showed that mentors needed support in terms of training in mentoring skills and logistical/financial support to carry out successful mentorship. Junior scientists and students reported that mentorship is not yet institutionalized and it is currently occurring in an adhoc manner. There was lack of awareness of roles of mentors and mentees. The mentors mentioned the limited number of practicing mentors at the college and thus the need for training courses and guidelines for faculty members in regard to mentorship at academic institutions.Both mentors and mentees were willing to improve mentorship practices at MAKCHS. There is need for institutional commitment to uphold and sustain the mentorship best practices. We recommend a collaborative approach by the stakeholders in global health promotion to build local capacity in mentoring African health professionals.Mentoring, defined as a partnership in personal and professional growth and development, is a core component of medical education and career success [1,2].
