Authors: Pogozheva A. V. , Sorokina E. Yu. , Sokolnikov A. A. 
Published: April 2019

Background: It has been shown that vitamin D availability depends on the body mass index (BMI). Genetic polymorphisms contribute to the development of vitamin D deficiency.Aim: To study the availability of vitamin D in the population of various regions of the Russian Federation, depending on the BMI values and the rs2228570 polymorphisms of the VDR gene and rs9939609 of the FTO gene.Materials and methods: The rs2228570 polymorphisms of the VDR gene and rs9939609 of the FTO gene were identified in 311 subjects (136, from the midland of Russia, and 175 from the Far North). Serum 25-hydroxyvitamin D [25(OH)D] levels were measured by an immunoenzyme assay in the autumn and winter seasons. Genotyping was performed with the allele-specific amplification and real-time detection of results using TaqMan probes complementary to the polymorphic DNA segments and the CFX96 Real Time System amplifier (Bio-Rad, USA). We studied associations of the rs9939609 polymorphism of the fat mass and obesity-associated (FTO) gene located at 16q12.2, as well as the rs2228570 polymorphism of the vitamin D receptor gene (VDR) located at 12q13.11.Results: Frank vitamin D deficiency (serum 25 (OH) D level<20 ng/ml) was observed in 39.7% (54/136) of the sample from the midland, in 40% (14/35) of the migrants and in 30.7% (43/140) of the indigenous inhabitants of the Far North (Nenets). Obese residents of the midland Russia had significantly lower serum 25(OH)D levels, and the indigenous population of the Far North had significantly higher levels than those with BMI<30 (р<0.05). In the indigenous population of the Northern Region, there was a significant association between vitamin D deficiency and C allele of the rs2228570 polymorphism of the VDR gene (odds ratio [OR] 2.5, 95% confidence interval [CI] 1.46–4.27, p=0.0006) and the AA genotype of the rs9939609 polymorphism of the FTO gene (OR 8.83, 95% CI 0.94–82.5, p=0.02).Conclusion: The association between obesity and vitamin D availability in the individuals with the rs2228570 polymorphism of the VDR gene and the rs9939609 polymorphism of the FTO gene depends on their ethnicity.

PERBANDINGAN HERMENEUTIKA DAN TAFSIR
Authors: Rahmawati Erik Sabti 
Published: April 2019

Hermeneutic as interpretation knowledge can be classified into three categories: objective, subjective, and liberation. 1). Objective hermeneutic means an effort to interpret and to understand the meaning of text as the author means. 2). Subjective hermeneutic means an effort to interpret and to understand the meaning of text based on the social context at this time without any consideration to the author thought. 3). Liberation hermeneutic means an effort to interpret and to understand the meaning of text based on the spirit of circumstance and try to make the result of interpretation as the spirit to change the life and the circumstance of the interpreter and the reader. In Islamic perspective, objective hermeneutic can be compared with tafsir bi al-ma’tsur, and subjective hermeneutic can be compared with tafsir bi al-ra’y. <br />However, hermeneutical discourse has been giving much contribution for the development of interpretation knowledge, so it can appear hermeneutic of liberation. It is a new penetration. If it is applied in Islam, interpretation does not only understand the meaning of al-Qur’an text as God means or based on the context, but also an effort how to make the result of interpretation as the spirit for Muslim society to change their society become better and the best.<br /><br />Keyword: hermeneutic, tafsir and tradision. <br />

Authors: Usman Mohammed 
Published: April 2019

<p>Effective trade unions in Nigeria play crucial roles in protecting the interest of their members. Without employee unions in Nigerian organization’s workers would be turned to slaves. Therefore, there is a need for employees to form unions for their welfare and well being. The paper aimed at examining the impact of employee involvement in trade unions on employee well being in Federal University Kashere of Gombe State Nigeria. Data were collected through interview and observation. The respondents of the study were the employees of Federal University Kashere who are members and some executives of ASUU, NASUU, SSANU and NAAT. Literature was reviewed through journal articles, bulletins, internet and prior knowledge on text books. The study found that the four trade unions in Federal University Kashere played significant roles in protecting the interest of their members which leads to the well being of the employees. The study recommended that the trade unions should seek for full certification from the national body to progress from an observer’s status in order to function fully. By pioneering research on staff unions in Federal University Kashere and adding on existing literature on trade unions, the paper contributes to knowledge.</p>

Published: April 2019

Abstract
Background: Erector spinae plane block (ESPB) is a novel local nerve block technique. However, evidence regarding the impact of ESPB on postoperative pain management after video-assisted thoracoscopic surgery (VATS) is lacking. This randomized controlled trial aimed to evaluate the effect of erector spinae plane block on postoperative analgesia and intra-operative opioid consumption for video-assisted thoracoscopic surgery patients.
Methods: We randomly allocated 91 participants to block with 30ml ropivacaine 0.375% (n=45), or no block without placebo or sham procedure (n=46). We analyzed results from 41 participants in each group ultimately. The primary outcome was postoperative NRS pain score. The secondary outcome was intra-operative sufentanil consumption. Postoperative QoR-40 scores and postoperative complications were also recorded.
Results: Erector spinae plane block reduced the median (IQR) pain scores during postoperative 0-1h, 1-6h, 6-12h and 12-24h: 3 (3-5) vs. 6 (5-7), p<0.0001; 5 (3-5) vs. 6 (5-7), p<0.0001; 4 (3-5) vs. 6 (5-7), p<0.0001 and 4 (3-5) vs. 5 (5-7), p<0.0001, respectively. Block also reduced the mean (SD) intra-operative total sufentanil consumption and per hour, per kilogram sufentanil consumption, as well as increased the median (IQR) global QoR-40 scores on POD1.
Conclusions: Erector spinae plane block can be used to reduce postoperative pain and intra-operative opioid consumption for VATS patients.
Influence of Selected Admixtures on the Microstructure of Renovation Plaster Mortars
Authors: BRACHACZEK Wacław 
Published: April 2019

Abstract
In the environment in which the renovation plaster mortars are exposed to moisture, followed by the crystallization of salt, their required durability is obtained by aeration. Aeration increases the porosity and resistance to salt crystallization, significantly changing the properties of plaster mortars. The paper presents the results of research on the influence of aeration and hydrophobizing admixtures on the porosity and pore size distribution in renovation plaster mortars. It was found that when aeration admixtures are used together with hydrophobizing admixtures, there may be problems with maintaining the proper degree of aeration of the mixture.

Published: April 2019

Abstract
Experimental testing of epoxy adhesives, which are commonly used in civil engineering for the strengthening of existing structures with composite products have been a topic of limited studies. It was due to the damage which usually occurred not in the adhesive layer but in the strengthened material. Recent studies have shown that the choice of an adhesive significantly affects the load-bearing capacity of the entire joint. The paper presents the results of strength tests of a selected methyl methacrylate adhesive, carried out according to the standards EN ISO 527-1 and EN ISO 527-2. Comparing the results to the data provided by the manufacturer (tested in accordance with ASTM D638) discrepancies have been found in the normative assumptions and consequently differences in the results. Experiments on the adhesive showed clear dependency on the speed of testing which revealed through variable characteristics after the elastic limit. Numerical simulations were also carried out assuming the elastic-plastic material model. The analyses allowed to obtain the distribution of stresses and deformations along the length of the sample and allowed to verify the length of the extensometer used. Comparison of results obtained for different measuring lengths of chosen adhesive confirmed the need to use extensometers in the testing of mechanical properties.
Soil Column Simulation of Natural Nutrient Flux after Short‐term Inundation
Authors: Collins R. J. , Mylavarapu R. S. , Clark M. W. , Osborne T. Z. 
Published: April 2019

Core Ideas
Intact soil column flood studies inaccurately capture short‐term nutrient flux.
Filter paper creates barrier to physical disturbance of soil into water column.
Filters are permeable to dissolved nutrients to chemically flux into water column.
Cone filters prevent floating soil and organic materials from entering water column.
Intact soil column studies have been widely used as laboratory simulations in determining the effects of long‐term inundation on nutrient flux in soils, but preliminary studies on total Kjeldahl N (TKN) have shown that physical disturbance associated with current flooding techniques causes an overestimation of TKN flux after short‐term inundation. Therefore, the objective of this study was to create a laboratory protocol that would minimize the effect of physical disturbance associated with current flooding procedures. To determine physical disturbance, total P concentrations were measured as a proxy for soil particles. Within 3 h of inundation, results found that total P concentrations in the water column were significantly reduced when using flat or cone‐shaped filter paper on the soil surface compared with blanks. By adapting the Collins‐filter barrier technique to short‐term flooding simulations, we were able to more accurately predict TKN flux to represent a natural real‐world response to short‐term inundation.

Core Ideas
There are many potential benefits of incorporating embryo culture into a doubled haploid program.
There is no known non‐transgenic method of selecting haploid embryos following embryo culture.
Our goal was to establish a non‐transgenic haploid selection method following embryo culture.
These methods allow early haploid selection based on differential root growth features.
Potential benefits of incorporating embryo culture (EC) into a doubled haploid (DH) program, including shortening the breeding cycle and increasing chromosome doubling rates, make the laborious and tedious task of excising embryos worth the effort. Difficulties arise during embryo selection considering the marker gene R1‐nj, which is typically used in DH programs, is not expressed in early stages after pollination. Although transgenic approaches have been implemented to bypass this issue, there is so far no known non‐transgenic method of selecting haploid embryos. The findings of this study reveal methods of selecting haploid embryos that allow the possibility of incorporating EC into a DH program without using transgenic inducers. The best performing method involves a machine‐learning classifier, specifically a support vector machine, which uses primary root lengths and daily growth rates as traits for classification. Selection by this method can be achieved on the third day after germination. By this method, an average false negative rate of 2% and false positive rate of 9% was achieved. Therefore, the methods presented in this research allow efficient and non‐transgenic selection of haploid embryos that is simple and effective.
Diurnal water use patterns for low-cost houses with indigent water allocation: a South African case study
Authors: Pretorius Dian , Crouch Melissa Lauren , Jacobs Heinz Erasmus 
Published: April 2019

Abstract
The diurnal water use patterns are of interest to hydraulic modellers, as these patterns are required for the design of water distribution systems. An extensive body of literature is available with regard to daily, weekly and seasonal diurnal water use patterns of typical suburban houses. However, the characteristics of South African low-cost houses, the socio-economic status of the consumers and the level of water service to such houses differs from typical western suburban houses reported on elsewhere. Notable differences include the limited access to heated water and negligible garden irrigation at the low-cost houses. Knowledge of water use in low-cost houses, which are prevalent in South Africa, is limited. To reduce this lack of knowledge, approximately 2.5 million flow records were collected over a period of 3 years from a sample of 14 low-cost houses as part of this empirical case study. Subsequently, a diurnal water use pattern was constructed for the selected low-cost houses at 15-minute and 1-hour resolution. The diurnal pattern is useful for hydraulic modellers when data that represent extended period time simulation of water networks in low-cost housing developments is required.

Abstract
Ozone has been widely used for water treatment all over the world. This study investigated the effects of pre-ozonation on N-nitrosodimethylamine (NDMA) formation from four drinking-water sources during subsequent chloramination. Moreover, relationships between NDMA and water-quality parameters (dissolved organic carbon (DOC), dissolved organic nitrogen (DON), hydrophobic fractions (HFs), positive-charged fractions (PCFs), ultraviolet absorbance at 254 nm wavelength (UV254), ammonia) were determined. The results indicated that NDMA formed directly by ozonation, but the concentrations (5.7–37.8 ng/L) were much lower than during chloramination (25.3–193 ng/L). Pre-ozonation slightly augmented NDMA formation from reservoirs, while it facilitated NDMA precursor destruction in the lake and river. The river was rich in organic matter, its DOC concentration was up to 4.97 mg/L, while the DON/DOC ratio (4.68%) was low; the lake possessed the most organic nitrogen and highest DON/DOC ratio (10.76%). HFs in reservoir #2 were low (1.27 mg/L), and the HFs/DOC ratio was especially high (73.4%). PCFs constituted 48.5–72.1% of DOC. UV254 values were in the range 0.081–0.175 cm−1. The ammonia concentration was high in the lake water (0.29 mg/L), while that in reservoir #2 was only 0.08 mg/L. There was a strong correlation between NDMA formation and the removal of ammonia, DON and PCFs.

Authors: Bellmunt-Bardas Josep M. , Pedro-Botet Juan , Chillarón Juan J. , Lund-Palau Helena , Caylà Joan A. 
Published: April 2019

Background:
Immigrants from countries with a high prevalence of Tuberculosis (TB) may constitute a source of infection.

Objective:
The aim of the present study was to describe a Tuberculosis (TB) screening programme at a primary health care centre directed at immigrants from countries with a high prevalence of TB.

Methods:
This was a descriptive study conducted at a primary health centre in Barcelona between 2009 and 2012 for immigrants from countries with a TB incidence > 100/100,000. They were invited to join the TB detection programme on registering at the primary health care centre when a reference nurse conducted a survey on socio-health data, performed a Tuberculin Skin Test (TST) and requested a chest X-ray. Interferon Gamma Release Assays (IGRA) were applied in individuals with positive TST or an abnormal X-ray.

Results:
Ninety-one (70.5%) of 129 individuals, aged 29.8 ± 9.8 years, who entered the programme, were men, 60 (46.5%) were from Pakistan and 3 reported previous TB. Eighty-six (66.7%) immigrants completed the study protocol. Three cases (2.3%) of TB were diagnosed and 29 (30.5%) had latent TB infection. Seven chest X-rays yielded other non-TB radiological changes.

Conclusion:
This TB screening programme should aid early detection of TB and LTBI among immigrants from high-TB prevalence countries on first registering at the primary health care centre.
El Corredor Magmático Intracratónico Pérmico-Triásico de la provincia de La Pampa, Argentina: nuevas edades U-Pb SHRIMP, composición isotópica de Hf e implicancias geodinámicas

Published: April 2019

Se ha realizado un estudio y revisión de las unidades magmáticas que integran el Corredor Magmático Intracratónico Pérmico-Triásico de La Pampa (CMPT-LP), centro-sur de Argentina. Se dan a conocer nuevas edades U-Pb SHRIMP, composición isotópica de Hf y composición química de algunas unidades integrantes del CMPT-LP: 1) Sienogranito Chacharramendi, edad 254.7 ± 1.3 Ma (Pérmico tardío, Lopingiano), edad modelo Hf de 1640 Ma con εHf promedio de -5.68; 2) Riolita Lihue Calel, 239.3 ± 1.5 Ma (Triásico Medio), edad modelo Hf de 1640 Ma con εHf promedio de -5.56. Esto indica que las dos unidades datadas fueron cristalizadas a partir de un fundido mantélico que incorporó corteza de edad statheriana tardía hasta calymmiana, tomando en cuenta también la edad modelo Nd de 1483 Ma del sector más distal (sudoriental) (Granito López Lecube) del CMPT-LP obtenida por otros autores.
Nuevos datos geoquímicos aquí aportados, analizados junto con datos geoquímicos previos, denotan la impronta o huella anorogénica –ambiente de intraplaca– del corredor magmático CMPT-LP, destacándose su consistencia con los granitos del tipo A1 debido a la similitud de sus fuentes con aquéllas de las que derivan los basaltos de islas oceánicas (OIB), como queda evidenciado, p. ej., en los cocientes Y/Nb <1.2. La pertenencia de las rocas del CMPT-LP mayoritariamente al tipo de alto potasio también es consistente con su ocurrencia en un ambiente tectónico de intraplaca. El ambiente anorogénico del CMPT-LP contrasta con aquél de la etapa tardía del Grupo Choiyoi propiamente dicho, que si bien también está asociada a extensión pérmica tardía – triásica temprana, ocurre en el contexto orogénico propio del Arco Magmático Choiyoi. Por tal razón se analiza la conveniencia de excluir el CMPT-LP del Grupo Choiyoi, en el que hasta ahora estaba incluido. Asimismo se comparan brevemente los marcos tectónicos de las fajas orogénicas lindantes del CMPT-LP: fajas de San Rafael (o Sanrafaélica, o Arco-Retroarco Choiyoi) y Gondwánides Norpatagónicos.

<p>El auge minero en determinados periodos históricos se debe a la incidencia de varios factores, como son el precio de los metales, el desarrollo de la tecnología, y las<br />políticas económicas y ambientales. El presente artículo reseña los principales periodos del desarrollo de la minería en México y profundiza en el más reciente: la aplicación de la automatización. La mayoría de los análisis sociales sobre la minería se enfocan en el concepto de neoextractivismo y hacen énfasis en las políticas económicas y los precios. La aportación de este estudio es sobre los datos de la revolución en las fuerzas productivas del sector minero, aspecto que puede ser igual de importante que los precios de los metales y la política económica en el sector para entender el contexto actual</p>
