EFFECT OF SOLVENT COMPOSITION ON THE ELECTROCHEMICAL PERFORMANCE OF HIGH-VOLTAGE CATHODE LiNi0.5Mn1.5O4
Authors: Man Tran Van 
Published: June 2018

The spinel LiNi0.5Mn1.5O4 (LNMO) is considered as an accurate cathode material for high-voltage Li-ions batteries above 4.5 V due to its high energy density, safety and eco-friendly. The electrochemical performance of spinel LNMO depends on the combability between electrode material and electrolyte. In this work, we reported the essential role of solvent compositions–carbonate solvents such as ethylene carbonate (EC), dimethyl carbonate (DMC), ethylene methyl carbonate (EMC)–in 1 M LiPF6 electrolytes on the long-term cycling test. The volumetric ratios in which the solvent compositions were varied were as follows: EC-EMC (7:3), EC-EMC (1:1), EC-DMC (1:1), EC-DMC (1:2). Result of cycling test in the solvent EC-EMC (7:3) leads to a discharge capacity of 140 mAh/g and a retention of 85 % initial capacity after 50 cycles.

Abstract

Background
This study was conducted to identify barriers and facilitators to cervical cancer screening, diagnosis, follow-up care, and treatment among human immunodeficiency virus (HIV)-infected women and clinicians and to explore the acceptability of patient navigators in Tanzania.

Materials and Methods
In 2012, we conducted four focus groups, two with HIV-positive women and two with clinicians who perform cervical cancer screening, diagnosis, follow-up care, and treatment. Transcriptions were analyzed using thematic analysis.

Results
Findings from the patient focus groups indicate the prevalence of fear and stigma surrounding cervical cancer as well as a lack of information and access to screening and treatment. The clinician focus groups identified numerous barriers to screening, diagnosis, follow-up care, and treatment. Participants in both types of groups agreed that a patient navigation program would be an effective way to help women navigate across the cancer continuum of care including screening, diagnosis, follow-up care, and treatment.

Conclusion
Given the fear, stigma, misinformation, and lack of resources surrounding cervical cancer, it is not surprising that patient navigation would be welcomed by patients and providers.

Implications for Practice
This article identifies specific barriers to cervical cancer screening and treatment from the perspectives of both clinicians and patients in Tanzania and describes the acceptability of the concept of patient navigation.
¿Qué significa integrarse en una sociedad liberal? La integración social vista desde el prisma de la discapacidad
Authors: Merklen Denis 
Published: June 2018

¿Cómo abordar el tema de la discapacidad desde el ángulo de la integración social? ¿En qué medida el problema de la discapacidad permite desplegar nuevos interrogantes sobre la problemática de la integración social? En este artículo intentaremos articular esas dos preguntas con el propósito de ubicar el problema que nos ocupa en una coyuntura precisa. En el marco de sociedades liberales, que sitúan al individuo en el centro de lo social, tanto las regulaciones y las protecciones sociales como las relaciones del trabajo pasan a un segundo plano. ¿Pero qué ocurre con el individuo discapacitado? ¿Qué lugar ocupan aquellos sujetos a quienes se les reconoce una forma de invalidez en la economía de la integración social de nuestras democracias liberales? ¿Y qué nos dice el lugar que se reserva a estos individuos en las formaciones sociales contemporáneas a propósito del régimen general de la integración social? Proponemos una “comparación en la historia”, siguiendo las recomendaciones de Robert Castel. Prestaremos una atención particular al tipo de política social que se promueve hoy en relación con el rol que se les atribuyó en el pasado.
Discapacidad intelectual y violencia de género: un análisis transnacional
Authors: Morcillo Martínez Juana María , Pérez Villar Juana 
Published: June 2018

Dentro de los múltiples factores que pueden originar situaciones de discriminación, la discapacidad se configura como un factor importante a tener en cuenta, problema que se ve agravado en función de los factores discriminatorios añadidos que puedan ir sumándosele. De este modo, si a dificultades intrínsecas que afrontan las personas con discapacidad le unimos la cuestión de género, nos encontramos con que las mujeres con discapacidad sufren una doble discriminación que las situará en una posición desigual con respecto a la población en general y hombres con discapacidad en particular. Por otro lado, la violencia de género, entendida como la manifestación de las relaciones sociales, económicas y culturales, que históricamente se han mantenido de forma desigual entre mujeres y hombres, se convierte por tanto, en un fenómeno de enorme calado que afecta, no sólo a la integridad física de las mujeres, sino al reconocimiento de su dignidad, donde se socava el principio básico de igualdad entre hombres y mujeres consagradas en la Constitución española. Por ello, el objetivo fundamental de este trabajo es analizar desde una perspectiva de género la situación actual de la mujer con discapacidad intelectual que sufre violencia de género, tanto españolas como de otras nacionalidades, poniendo de manifiesto que la característica más notable a destacar, es su sustentación en las desigualdades de género.

Authors: Meshram Rajkumar M. , Patil Ashwini 
Published: June 2018

Background: Although, diphtheria is eliminated by many developed countries by effective immunization, still diphtheria continues to be endemic in India and leading cause of morbidity and mortality, especially in areas in the border of the two states. The objective of the present study was to recognize the clinical profile, morbidity and mortality pattern of diphtheria and to study their immunization status as a retrospective observational study performed in pediatric wards and paediatric intensive care unit.Methods: The medical records were recovered from the case files, searching for cases diagnosed as diphtheria from the Medical Record Section and Statistical Service of the institute. A pre-established protocol was formed after approval from institutional ethical committee. Case study included suspected, probable and confirmed cases of diphtheria as per the WHO definition guidelines. All the relevant data and information regarding age, gender, residence, socioeconomic status, immunization status, clinical details, laboratory investigation, complications, and treatment provided, and outcome were recorded.Results: Amongst 47 patients, 55.32% were >5years and mean age was 6.46±3.08 years with no difference in sex distribution. 2(4.25%) patients were completely immunized, 27(57.45%) were partially immunized and 18(38.30%) were not immunized. An immunization rate was less in females as compared to males. All patients presented with fever and membrane in throat followed by throat pain 95.74%, enlarged/congested tonsils 80.85%, respiratory difficulty 68.08%, dysphagia 59.57% bull neck 48.94% and voice change 36.17%. Myocarditis was the commonest (42.55%) complication followed by palatal palsy (14.89%), polyneuropathy (8.51%), acute renal failure (4.25%) and DIC & shock (4.25%) were observed. Case fatality rate was 21.28%. Maximum numbers of cases were noted during the rainy season.Conclusions: Shifting of occurrence of diphtheria in the age group of 5-15 years suggest the need to improve and strengthen the immunization activity specially booster doses in the border districts as most of the cases were from areas at the border of two states.
Moyamoya disease: a case report
Authors: Sehgal Parul , Wasim Sanober 
Published: June 2018

Moyamoya disease is a chronic, progressive occlusion of the circle of Willis arteries that leads to the development of characteristic collateral vessels seen on cerebral angiography. The appearance of these small, multiple vessels at the base of the brain resembles “puff of smoke”. The disease may develop in children and adults, but the clinical features differ. Children are likely to suffer with ischemic or haemorrhagic stroke. In the present report, authors describe a 7-year-old female with history of recurrent stroke apraxia and atrophy of left side with facial nerve palsy and was later on diagnosed with Moyamoya disease at HIMS Dehradun. Conclusion: Child with Moyamoya disease presents with recurrent episodes of sudden hemiplegia that might occur on alternate sides. The disease is progressive and dynamic in children. MRA clinches the diagnosis and neurosurgical intervention may be required as a part of definitive management.

Published: June 2018

Background: Cardiovascular disease (CVD) has a major impact on both developed and developing nations as it has become as a leading cause of death all over the World. In recent years an increasingly robust body of epidemiological evidence has highlighted the proliferation of CVD risk factors worldwide. The westernization of dietary habits, decreased levels of physical activity, increased childhood obesity and increased tobacco consumption accelerated by industrialization, globalization now threaten once low risk regions. The project aims to establish the need for screening, risk assessment, education and management in young adults. Objective of the study was to assess the risk behaviours in relation to smoking habits, alcohol use, sexual promiscuity among college going youth populace in southern part of Calicut.Methods: A cross-sectional study was conducted among college students aged 18-25 years around Calicut city. Study was conducted during the months of June 1st and July 30th 2016. The colleges were selected using simple random sampling method and the partakers were interviewed after getting assent from the concerned institutions. The sample size was calculated as 200 from WHO Global health observatory data prevalence of tobacco usage as 51%.Results: Mean (SD) age of study population is 20.90 (±2.11). Majority of the study population were females (78.5%) and males were 21.5%. Prevalence of smoking found to be 4% and alcohol consumption was found to be 2.5% among study population. BMI of the study population is 21.04 (±3.73).Conclusions: The results of this survey are alarming that the college going youth population fail to understand the devastating consequences of risky behaviours. Hence, interventions must be designed to prevent high-risk behaviours among the vulnerable population.

A Novel Digital Approach to Predict Production Rates from PCP Wells
Authors: Álvarez Julieta , Espinola Oswaldo , Ramírez Christian , Torres Adelfo 
Published: June 2018

Abstract
Progressive cavity pumps (PCP) have been used as artificial lift system for heavy oil lifting, low productivity wells and other challenging conditions which are common characteristics of brownfields. In addition to those conditions, there is the current complicated economic environment in which operating companies seek to reduce investments while enhancing field production operations with low-cost solutions aiming to increase the overall's field recovery factor.
The initial step when trying to enhance field production operations in wells operating with PCPs as artificial lift system is performing a well-level analysis. During this analysis, the existing operational conditions and its corresponding production are evaluated. The continuity and accuracy of this analysis is highly dependent on the data input for analysis purposes. For instance, the rate of production is required as input and due to the nature of operation in brownfields, this value is not measured with the required frequency needed for performing a proper production enhancement analysis.
This paper aims to provide a simple, automated, and accurate way to perform a calculated rate of production that is cost effective and easy to maintain, capable of being used during field production operations enhancement analysis, and applicable to wells operating with PCPs as artificial lift in heavy oil conditions, using regression and analytical methods.
Both methods are being used part of a digital oilfield solution implemented in a heavy oil brownfield with telemetry-instrumented PCP wells. This solution is working inside a production operations platform that validates input data, manages different frequencies and types of data, and automatically calculates a production rate, which is then pushed to a visualization dashboard.
Results provide an accurate production rate estimate suitable for reservoir engineering analyses while providing insight for the production operations enhancement.
Hydrologic processes of groundwater in a small monsoon-influenced mountainous watershed

Published: June 2018

AbstractMountain block recharge is the least well quantified owing to the lack of a thorough understanding of mountain block hydrological processes. Observations of spatio-temporal variations of groundwater were employed to clarify hydrologic processes in a semi-arid mountainous watershed of northern China. Results showed that the annual feeding rate of precipitation changed between 21% and 40%. However, infiltration of precipitation was mainly drained as interflow on slopes and recharged into the mountain valley as focused recharge. As a result, the mean correlation coefficient between precipitation and groundwater level was only 0.20 and seasonal variations were reduced. Mountain slope is essentially impermeable with no bedrock percolation under arid circumstances. Only a bedrock percolation event occurred after multiple closely-spaced heavy rains during the four-year observation, which induced a local rapid ascending of the water table and an enhanced lateral recharge from upgradient watersheds. The influence of the enhanced lateral recharge lasted three years, suggesting a huge groundwater catchment overcoming local watershed divides in mountain blocks. The average of the gradual recession of the water table was 5.1 mm/d with a maximum of 11.4 mm/d in the beginning stage. Both interflow and bedrock percolation are important. Our results highlight the changeability of hydrologic processes in mountain watersheds.
Multi-date trends in groundwater pollution from pit latrines
Authors: Dzwairo Bloodless 
Published: June 2018

Abstract
This paper provides a multi-date review of trends in groundwater pollution from pit latrine sanitation structures using global, regional and South African cases. The paper focuses on three parameters which are microorganisms, nitrate and phosphorus, which are aligned with the challenge of waterborne diseases, and generally linked to poor water quality, and inadequate sanitation and hygiene. Poor sanitation and hygiene open up transmission routes for ingestion of faecal matter, which as at 2018 continue to pose risks of diarrhoea, opportunistic infections, and consequent malnutrition. These challenges currently account for approximately 1.7 million deaths annually, of which more than 90% are in developing countries, which have low sanitation coverage. While pit toilets are the generally preferred form of sanitation technology for developing countries, most provide evidence of the interconnectedness between the structures and groundwater pollution. The mechanism of pollution is generally indicated to be seepage of polluted pit latrine leachate into groundwater. This specific type of microbial and chemical routing from toilets into the environment increases the prevalence of diseases. These diseases usually result in high mortality for developing countries. Therefore, this review has highlighted the need to minimize pollution of groundwater from pit latrines, thereby contributing towards sustainable water quality management.
Enhanced biosorption of Cr(VI) using cotton fibers coated with chitosan – role of ester bonds
Authors: Rojas Sergio I. , Duarte Diana C. , Mosquera Sergio D. , Salcedo Felipe , Hinestroza Juan P. , Husserl Johana 
Published: June 2018

Abstract
We report on the role of ester bonds in the enhanced removal of hexavalent chromium from water using cotton fibers coated with chitosan. Adsorption capacities up to five times higher than those of the unmodified fibers were observed when the cotton fibers were exposed to an NaOH, followed by citric acid (0.97 M), and a chitosan solution (2%). We found that the use of NaOH favors the formation of ester bonds over amide bonds on the surface of the cotton fibers. This increase in the surface density of ester bonds generates an increase in the amount of exposed amino groups from the chitosan, hence increasing the removal capacity of the modified fibers. Experimental results also reveal that the adsorption is induced by the electrostatic attraction between the protonated amino groups on the surface and the negatively charged chromium ions in the water. Adsorption isotherms and kinetic studies indicated that the adsorption process fits the Langmuir and the Freundlich isotherm models as well as the pseudo-first and pseudo-second order kinetic models. These results can open a new avenue for the manufacturing of fibers with enhanced removal capacities for hexavalent chromium.
Circulating Biomarkers in Migraine: New Opportunities for Precision Medicine
Authors: Ferroni Patrizia , Barbanti Piero , Spila Antonella , Fratangeli Federica , Aurilia Cinzia , Fofi Luisa , Egeo Gabriella , Guadagni Fiorella 
Published: June 2018

Background:
Migraine is the most common neurological disorder and the second
most disabling human condition, whose pathogenesis is favored by a combination of genetic,
epigenetic, and environmental factors. In recent years, several efforts have been made to identify
reliable biomarker(s) useful to monitor disease activity and/or ascertain the response to a
specific treatment.

Objective:
To review the current evidence on the potential biological markers associated with
migraine.

Methods:
A structured search of peer-reviewed research literature was performed by searching
major publications databases up to December 2017.

Results:
Several circulating biomarkers have been proposed as diagnostic or therapeutic tools
in migraine, mostly related to migraine’s inflammatory pathophysiological aspects. Nonetheless,
their detection is still a challenge for the scientific community, reflecting, at least in part,
disease complexity and clinical diagnostic limitations. At the present time, calcitonin generelated
peptide (CGRP) represents probably the most promising candidate as a diagnostic
and/or therapeutic biomarker, as its plasma levels are elevated during migraine attack and decrease
during successful treatment. Other molecules (including some neuropeptides, cytokines,
adipokines, or vascular activation markers) despite promising, do not possess the sufficient
prerequisites to be considered as migraine biomarkers.

Conclusion:
The characterization of migraine-specific biomarkers would be fundamental in a
perspective of precision medicine, enabling risk assessment and tailored treatments. However,
speculating on the clinical validity of migraine biomarkers may be premature and controlled
clinical trials are presently needed to investigate both the diagnostic and therapeutic value of
these biomarkers in migraine.
