Though vegetarians own the privilege of a wide range of health benefits and of much lower risk of many diseases, they are also cut off many essential nutritional values. This study aimed to determine the vegetarian practices, body composition and dietary intake of vegetarians among Hindus and Buddhists in Kuching, Sarawak. Using questionnaire and anthropometric measurement, this cross-sectional study was carried out in Hindu and Buddhist temples in Kuching. Data was entered and analysed using SPSS version 22. A total of 114 respondents participated in the study, with mean age of 45.8 years (SD±16.01), females (57%), and majority Buddhists (81.6%). Majority of the respondents were on lacto-ovo vegetarian diet (71%) with more among the Hindus. More than half of the respondents were overweight and obese (64.1%). About 58% of the respondents were found to have abnormal waist circumference and 78.1% with over fat percentage. Buddhist respondents consumed more carbohydrates than Hindus. Hindu respondents consume more macro-nutrients such as protein and fat with a mean intake of 102.9 g (SD ±34.60) and 20.9 % of total energy intake respectively and more micro-nutrients. Vegetarian diet does not warranty healthy body as the quality and quantity of the food intake can influence the nutritional status of a person. Knowledge on choice of food should be imparted to improve their health status.

Bonos verdes versus bonos convencionales: ¿existe una demanda diferenciada en México?
Authors: Arellano Cadena Rogelio , Pérez Delgado Lucía 
Published: October 2019

¿Es la demanda de bonos verdes diferente a la demanda de bonos convencionales? A partir del estudio seminal de Fama y French (2007) quienes consideraron que la demanda de activos financieros, además de criterios de rendimiento y riesgo, podría explicarse por motivos no pecuniarios, diversos trabajos han intentado responder a esta pregunta (Asian Bond Monitor, 2018; Ehlers y Packer, 2017; Reboredo, Quintela y Otero, 2017; Östlund, 2015, y Zerbib, 2016, 2019). La mayoría de los resultados indican que los bonos verdes otorgan un rendimiento inferior a aquel pagado por los bonos convencionales. Ello hace concluir que sí existe una demanda diferenciada de este tipo de bonos. Hasta ahora, no se cuenta con estudios que realicen esa comparación para el caso de México.
El presente análisis pretende cerrar esa brecha, intentando identificar si existe una diferenciación por parte de los inversionistas en México entre su demanda de un bono verde y de un bono convencional. Para ello, se utilizan las posturas de compra (ask price) para dichos bonos emitidos por la misma institución, ya sea en la misma fecha o con el mismo plazo de vencimiento. Los resultados sugieren que la distribución de las posturas de compra difiere entre uno y otro tipo de bono y que, cuando los bonos tienen el mismo plazo de vencimiento, los inversionistas están dispuestos a aceptar rendimientos ligeramente inferiores en bonos verdes.

The practice of regular physical activity is paramount for health promotion, which by definition involves physical, psychological, emotional and social aspects. These factors influence the quality of life, which is nothing more than the degree of personal satisfaction with life. People with physical disabilities tend to have higher rates of a sedentary lifestyle when compared with the population in general, and this may influence their Self-Perception of Quality of Life (SPQL) negatively. The study aimed at evaluating/comparing SPQL among sport participants and non-sport participants with spinal cord injury. 20 people with spinal cord injury (75% Male and 25% Female) participated in the study, they were divided in two groups. Group 1 (n=10) Sport Participants with an average age of 41,1±13,9 years, and the Group 2 (n=10) Non-Sport Participants with an average age of 37,9 ±12,8 years. As a collection instrument, two questionnaires were used, one to assess the Quality of Life (Medical Outcotnes Study 36 - Item Short - (SF36)), and the other aiming to analyze the sociodemographic profile of the participants (created by the authors). The results showed that only for the Physical Aspects of SPQL there was a statistically significant difference, where G1 had a higher score than G2. Regarding the labor profile of the groups, in G1, 80% are retired due to disability, already in G2, this number drops to 40%. It can be concluded that non-sport participants of this research are more involved in work activities, but the group engaged with sports enjoys a better SPQL in the physical aspects.

The local structure of Ta(v) aqua ions in high temperature fluoride- and chloride-bearing solutions: Implications for Ta transport in granite-related postmagmatic fluids
Authors: Anderson Alan J. , Mayanovic Robert A. , Lee Thomas 
Published: October 2019

Abstract
The local structure of Ta(V) in high-temperature fluoride- and chloride-bearing acidic solutions was investigated using in situ X-ray absorption spectroscopy (XAS). All XAS spectra were collected from two solutions, designated A and B, at beamline ID-20-C at the Advanced Photon Source, Argonne National Laboratory. Spectra were collected from solution A at 350 and 400 °C and from solution B at 25, 360, and 400 °C after the solutions were sealed in a hydrothermal diamond anvil cell. Solution A was prepared by dissolving Ta2O5 powder in 5% HF solution; solution B consisted of TaCl5 dissolved in 2% HF. The dominant tantalum species in solution A at elevated temperatures was TaF83–. In contrast, TaCl6–, which was the dominant complex in solution B at room temperature, disappeared as hydroxide complexes with an average ligand number between 5 and 7 became the dominant species at 350 and 400 °C. The XAS results confirm the previously recognized effect of fluoride activity on Ta speciation in hydrothermal fluids and suggest that both fluoride and hydroxide complexes play an important role in the transport of Ta in acidic fluoride-bearing solutions involved in the formation of mineralized mica-rich replacement units in granitic pegmatites.

Core Ideas
‘Fiskeby III’ harbors a combination of abiotic stress traits, including iron deficiency chlorosis (IDC) tolerance.
An IDC quantitative trait locus on chromosome Gm05 was identified in genome‐wide association studies and biparental populations.
Fine‐mapping resolved a 137‐kb interval containing strong candidate genes.
Iron deficiency chlorosis (IDC) is an important nutrient stress for soybean [Glycine max (L.) Merr.] grown in high‐pH soils. Despite numerous agronomic attempts to alleviate IDC, genetic tolerance remains the most effective preventative measure against symptoms. In this study, two association mapping populations and a biparental mapping population were used for genetic mapping of IDC tolerance. Quantitative trait loci (QTLs) were identified on chromosomes Gm03, Gm05, and Gm06. Heterogenous inbred families were developed to fine‐map the Gm05 QTL, which was uniquely supported in all three mapping populations. Fine‐mapping resulted in a QTL with an interval size of 137 kb on the end of the short arm of Gm05, which produced up to a 1.5‐point reduction in IDC severity on a 1 to 9 scale in near isogenic lines.
Les enfants enfermés, une histoire sans fin…
Authors: Blanchard Véronique 
Published: October 2019

Cet article se propose de reprendre l’histoire de la détention des enfants depuis le xix e en France. Il s’agit non seulement de décrire et comprendre les modalités de l’enfermement des mineurs de justice en deux siècles mais également de s’interroger sur la permanence de ce système. De La Petite Roquette, première prison réservée aux enfants, aux Établissements pénitentiaires pour mineurs ( epm ) des années 2000, il faut se souvenir que la France est un pays qui n’a jamais souhaité abolir l’incarcération des enfants et adolescents. Est-ce à dire que la (ré)éducation des jeunes délinquants ne peut se passer des murs de la prison et de l’enfermement ? Une approche diachronique doit permettre de répondre à cette interrogation en insistant sur les évolutions du regard social concernant la déviance et la criminalité juvéniles.

Published: October 2019

Abstract
Aim: Childhood cancer patients are subjected to recurring painful medical procedures. In low- and middle-income countries (LMIC), where the majority of the world’s childhood cancer patients live, pain management is often unsatisfactory due to limited resources. This study aimed to evaluate the possibility of conducting a preprocedural preparation for lumbar punctures (LPs) at a pediatric oncology unit in a LMIC and to assess whether this intervention would decrease procedural pain and fear. Methods: Patients aged 5–18 who underwent LPs between February 25, 2017, and April 12, 2017, were eligible and invited to participate. Included patients were interviewed to assess the procedural pain and fear in conjunction with the LP and the patients’ understanding of why an LP was done. Closest caregivers and the medical staff were interviewed to compare the perceptions of pain. The study was conducted in two separate phases; patients included in the period of February 25–March 9 underwent LP according to routines without preparation while patients included in the period of March 10–April 12 received procedural preparation with information. Results from the interviews from the two study groups were compared. Results: Out of 79 patients who met the inclusion criteria, 76 were included and preparation was successfully implemented for 25 of them. The pain decreased significantly (P = 0.022) after preparation. The physicians underestimated the patients’ pain (P < 0.0001). The understanding of the reason for the LP increased significantly among patients (P = 0.0081) and their caregivers (P < 0.0001). Conclusions: Preparation by preprocedural information, created to fit the situation at a state-run hospital in a LMIC, is feasible and efficient.
