Abstract
The stannides REIr2Sn4 (RE=La, Ce, Pr, Nd, Sm) were synthesized from the elements by arc melting or by induction melting in sealed niobium containers. They crystallize with the NdRh2Sn4 type structure, space group Pnma. The samples were characterized by powder X-ray diffraction (Guinier technique). Three structures were refined from single-crystal X-ray data: a=1844.5(2), b=450.33(4), c=716.90(6) pm, wR2=0.0323, 1172 F

Determination of Coal Pillar Width and Support Parameters in Deep Coal Mines—A Case Study
Authors: Chen Shi-hai , Zhang Zi-hua 
Published: July 2018

Abstract
With the depletion of shallow mineral resources, many large mines have turned to deep mining. The mine pressures associated with deep mining activities induce severe damage and deformation in the surrounding rock. The stability of coal pillars in the mining area is an important factor in maintaining roadway stability, so reasonable retainment of coal pillars is a primary issue in safety production. In this article, the stresses on coal pillars and roadways under different coal pillar widths are analyzed with ABAQUS software (Dassault Systèmes, Vélizy-Villacoublay, France). The result is a reasonable coal pillar width of the first mined face in the Kongzhuang mine, which was determined to be approximately 5 to 7 meters. This width ensures that the coal pillar will not be crushed or fractured and avoids both spontaneous combustion of the coal and waste of resources. The roadway’s support parameters are determined by empirical calculation and then verified by numerical simulations and field tests. The reasonability of the arrangement of bolts and cables are verified in the same fashion.
Effect of CuO Nanoparticles on Rheological Behavior of ISO VG46, Jatropha Oil, and Their Blend

Published: July 2018

Abstract
This article presents experimental results on the mixing of CuO nanoparticles in ISO VG 46 oil, Jatropha oil, and a blend of the two oils. Initially, blend oil was prepared by mixing ISO VG46 and Jatropha oil in a fixed proportion. This blending caused a reduction in the viscosity of the oil mix as compared to the ISO VG46 oil. Therefore, to bring the viscosity of the blend oil to the level of the ISO VG46 oil, various concentrations of CuO nanoparticles were added to the blend to prepare stable nano-blend oils. The stability of the blend oil, ISO VG46, and Jatropha oil-based nano-lubricants was checked by measuring viscosity at regular intervals of time, and it is observed that stability decreases with the increase of CuO loading in base fluid. Viscosity values of nano-blend oils for various concentrations of CuO ranging from 0 to 3 wt. % were measured. These values were compared to the viscosity values of ISO VG46 and Jatropha oil-based nano-lubricants with the same CuO concentrations. About 19, 17, and 20 % enhancement in viscosity was observed in the blend oil, ISO VG46 oil, and Jatropha oil-based nano-lubricants, respectively, for 3 wt. % concentrations of CuO at 30°C. The nano-blend oil showed inferior performance up to 2 wt. % concentration of CuO in the entire temperature range (30 to 60°C). The viscosity of the nano-blend oil dispersing with 3 wt. % concentration matched well with the viscosity of ISO VG46 mineral oil. Furthermore, the experimental viscosity data of all the types of nano-lubricants are compared to the different viscosity models, and it is observed that the viscosity of the nano-lubricants closely matched with a viscosity model available in the literature. It is observed from viscosity sensitivity analysis that viscosity is more sensitive to greater concentration. The studies on the effects of nanoparticles’ concentration on density and friction coefficients revealed that the addition of nanoparticles in base oils had a small impact on pumping power.

Published: July 2018

Background
During intensive BP lowering, acute declines in renal function are common, thought to be hemodynamic, and potentially reversible. We previously showed that acute declines in renal function ≥20% during intensive BP lowering were associated with higher risk of ESRD. Here, we determined whether acute declines in renal function during intensive BP lowering were associated with mortality risk among 1660 participants of the African American Study of Kidney Disease and Hypertension and the Modification of Diet in Renal Disease Trial.

Methods
We used Cox models to examine the association between percentage decline in eGFR (<5%, 5% to <20%, or ≥20%) between randomization and months 3–4 of the trials (period of therapy intensification) and death.

Results
In adjusted analyses, compared with a <5% eGFR decline in the usual BP arm (reference), a 5% to <20% eGFR decline in the intensive BP arm was associated with a survival benefit (hazard ratio [HR], 0.77; 95% confidence interval [95% CI], 0.62 to 0.96), but a 5% to <20% eGFR decline in the usual BP arm was not (HR, 1.01; 95% CI, 0.81 to 1.26; P<0.05 for the interaction between intensive and usual BP arms for mortality risk). A ≥20% eGFR decline was not associated with risk of death in the intensive BP arm (HR, 1.18; 95% CI, 0.86 to 1.62), but it was associated with a higher risk of death in the usual BP arm (HR, 1.40; 95% CI, 1.04 to 1.89) compared with the reference group.

Conclusions
Intensive BP lowering was associated with a mortality benefit only if declines in eGFR were <20%.

Objective: to assess short-term and long-term outcomes of right hemicolectomy with extensive lymph node dissection using the experience of one clinic.Materials and methods. This retrospective study analyzed data from a prospectively collected database containing information on all patients with right-sided colon cancer that underwent laparoscopic right hemicolectomy with D3 lymph node dissection between 2013 and 2018. We estimated intraoperative blood loss, surgery duration (taken from anesthetic records), frequency of postoperative complications, length of in-hospital stay, duration of lymphorrhea, time to gastrointestinal recovery, integrity of the mesocolon, number and location of removed lymph nodes.Results. A total of 50 underwent laparoscopic right hemicolectomy with D3 lymph node dissection. No cases of surgical conversion were registered. Median surgery duration was 185 min; median blood loss was 30 mL. No postoperative mortality was observed in the study cohort. Twelve (24 %) patients had postoperative complications; 2 (4 %) patients underwent repeated surgery. Median number of lymph nodes examined was 26; high-quality specimens (G ) were obtained in 48 (96 %) patients. At a median follow-up of 19.5 months, 2 (4 %) patients had disease progression (developed liver metastases).Conclusion. Our results confirm safety of laparoscopic approach for right colon resection with D3 lymph node dissection

Published: July 2018

Background. The effect of anastomotic leakage (AL) on oncological outcomes after total mesorectumectomy is controversial.Objective: to investigate the influence of AL and other factors on oncological outcome.Materials and methods. Data of 67 patients underwent total mesorectumectomy with normal healing were compared with those for 16 patients who experienced AL. Long-term oncological outcomes were analysed.Results. Median follow-up was 43 months. AL rate was 19.4 % (16 cases out of 83). Following factors had negative influence on lower 4-year disease-free survival rate and reached statistical significance in univariant analysis: tumor invasion (hazard ratio (HR) 8.8; 95 % сonfidence interval (CI) 1.4–13.7; р= 0.01), metastases in regional lymph nodes (HR 3.5; 95 % CI 1.2–12.3; р= 0.03), tumor stage (р= 0.048), level of tumor differentiation (HR 0.1; 95 % CI 0–0.6; р<0.0001), tumor stenosis (HR 8.8; 95 % CI 1.4–13.7; р= 0.002), AL (HR 3.9; 95 % CI 1.6–37.1; р= 0.01). In the logistic regression analysis independent risk factors for the development of recurrence were not revealed.Conclusion. AL was not proved to be a risk factor of worse oncological outcome. Hence, additional adjuvant treatment or extended follow-up on the basis of the occurrence of AL after low anterior resection of rectal cancer might not be justified.
Emergency resections in patients with complicated rightand left-sided colon cancer: long-term outcomes
Authors: Schaeva S. N. 
Published: July 2018

Objective: to evaluate five-year overall and relapse-free survival in patients with complicated rightand left-sided colon cancer that underwent emergency resection.Materials and methods. The study included 501 patients with urgent complications of rightand left-sided colon cancer that underwent emergency resection. The data was obtained from an electronic register containing the information on patients with urgent complications of colorectal cancer treated in general and specialized surgical hospitals in Smolensk between 2001 and 2013 (13 years). We assessed fiveyear overall and relapse-free survival in these patients.Results. A total of 501 resections were performed during the study period. We observed significant differences in resection statuses of patients after emergency resection: the R1 resection status was more frequent in individuals with right-sided colon cancer compared to those with left-sided colon cancer (20.8 % vs. 6.9 %, p = 0.0002). Mean number of lymph nodes examined was 4.6 ± 2.0 in patients with right-sided cancer and 5.3 ± 3.0 in patients with left-sided cancer (p = 0.18). There were no differences in the number of patients receiving adjuvant treatment between the groups (p = 0.11). Patients with left-sided stage II/IIIB/IIIСcomplicated colon cancer demonstrated better overall and relapse-free survival than those with right-sided tumors of the same stages (overall survival: p = 0.007, p = 0.0002, p = 0.0001 for stages II, IIIB, IIIСrespectively; relapse-free survival: p = 0.005, p = 0.0003, p = 0.0002 for stages II, IIIB, IIIСrespectively).Conclusion. The observed differences in the outcomes of treatment for rightand left-sided complicated colon cancer can be explained by the fact that the majority of emergency resections for right-sided tumors were one-stage and were performed in general surgery hospitals. Patients with left-sided cancer underwent tumor removal on the second stage more often than those with right-sided cancer (32 % vs. 13 %). Treatment of patients with complicated colon cancer should be consistent, stepwise, and pathogenetically reasonable.

Objectives.According to literature and experts, prostate cancer (PC), breast cancer (BC), colon cancer (CC), melanoma (MEL) and renal cell carcinoma (RCC) are the most high-cost oncological diseases. The aim of our study was to calculate the charges for each of these nosologies from the point of view of Moscow’s budget and compare them with each other.Methods.To assess the annual costs of drug therapy in Moscow in patients with PC, BC, CC, MEL and RCC there has been developed an analytical model in MS Excel software, considering the data of Cancer Register, as well as literature sources.Results.There has been estimated that if the costs of drug therapy for all five of assessed types of cancer are taken as 100 %, then the most costly is BC (41 % of costs), then MEL (20 %), RCC (15 %), CC (13 %) and PC (12 %). There has been also calculated, that if the number of patients with all five types of assessed cancer undergoing drug therapy, we would consider as 100 %, the highest percentage of them is in BC (50 % of all patients), then PC (36 %), CC (9 %), MEL (3 %) and RCC (1 %).Conclusions. The structure of drug therapy costs in patients with PC, BC, MEL, CC and RCC in Moscow shows that the most expensive is the treatment of patients with melanoma (for 3 % of patients Moscow City Health Department spends 20 % of charges) and RCC (1 % of patients spends 15 % of charges).

El objetivo de este estudio fue determinar la influencia de la cobertura vegetal en la composición, la estructura y la diversidad de la ictiofauna en las quebradas de las zonas de vida de los bosques húmedo premontano (bh-PM) y muy húmedo premontano (bmh-PM) del Alto Magdalena, Colombia. Para esto, se muestrearon 23 estaciones distribuidas en las coberturas vegetales de pastos, mosaico de cultivos, arbustos y bosques en las diferentes zonas de vida. En cada estación se establecieron transectos longitudinales (100 m/ancho variable); los peces se capturaron con un equipo de pesca eléctrica y una red de arrastre (5 m x 1,5 m, ojo de malla de 0,05 m), y se evaluaron paralelamente algunas variables ambientales. La estructura y la diversidad de la ictiofauna se calcularon mediante el uso de modelos estándar. En cuanto a la diversidad, medida con números de Hill, no hubo diferencias significativas entre las coberturas vegetales en el bh-PM. Sin embargo, en el bmh-PM la cobertura de pastos fue la más diversa. En el análisis de escalamiento multidimensional no métrico, no se evidenciaron diferencias en la estructura del ensamblaje de peces en los tipos de cobertura vegetal, sin embargo, en el análisis canónico de correspondencias se evidenció que la cobertura de dosel, la calidad de la vegetación de ribera y la elevación influyeron de manera significativa en la composición y la distribución de la ictiofauna. Si bien la cobertura de pastos presentó la mayor diversidad íctica, es un hábitat con degradación del bosque de ribera y cambios en la temperatura, idóneo para el establecimiento de especies tolerantes e invasoras. © 2018.

La influencia de los roles de género en el consumo de alcohol: estudio cualitativo en adolescentes y jóvenes en Asturias
Authors: Fernández Rodríguez María Aránzazu , Dema Moreno Sandra , Fontanil Gómez Yolanda 
Published: July 2018

A pesar del desarrollo de políticas de prevención dirigidas a abordar el consumo de alcohol en adolescentes y jóvenes, durante la última década se ha producido un aumento considerable de quienes realizan un consumo abusivo de esta sustancia en España. Las encuestas oficiales sobre este fenómeno muestran un acercamiento entre varones y mujeres en las prevalencias de consumo y en los consumos de riesgo, e incluso una mayor incidencia de estas conductas en el caso de las mujeres al final de la etapa adolescente. El objetivo de este artículo es conocer la influencia que ejercen los roles de género en estas pautas de consumo en adolescentes y jóvenes. Para ello, se han realizado grupos focales que han permitido identificar las similitudes y diferencias que se producen tanto en las prácticas de consumo y abuso del alcohol que desarrollan estos colectivos, como en el significado social que unos y otras atribuyen a las citadas prácticas. Los resultados obtenidos muestran que las variables género y edad actúan de forma combinada en el aprendizaje del consumo de bebidas alcohólicas, así como en las motivaciones y expectativas que los y las adolescentes y jóvenes tienen sobre dichas prácticas. Además, en este estudio se identifican tres etapas diferenciadas, en la primera de ellas los roles de género se encuentran claramente definidos, en la segunda se observa cierta transgresión de los mismos fundamentalmente por parte de las mujeres y en la última se advierte una vuelta a los tradicionales roles de género.
