Published: December 2020

Abstract
Background: Most of the studies assessing the corrective posterior total hip arthroplasty (THA) mainly focused on the mini-incision approach. Studies exploring the short external rotator sparing approach are rare. Therefore, this study aimed to compare the effectiveness of standard posterior approach and short external rotator sparing approach.Methods: This prospective observational study included 126 patients who underwent THAin 06/2017-06/2018. Patients were assigned to standard (standard posterior approach) and corrective (short external rotator sparing approach) groups based on the surgical method. Surgical data were recorded postoperatively. Postoperative hip joint recovery was assessed using the times to ambulation and independent stair use, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, Harris score, and Oxford hip score (OHS) at 2 and 8 postoperative weeks. The visual analog scale (VAS) was used for postoperative pain assessment.Results: Postoperative changes of creatine kinase (CK), myoglobin, CRP, and prosthesis position were similar in both groups (P > 0.05). However, intraoperative blood loss (P < 0.001) and postoperative 6-hour drainage volume (P = 0.03), hospital stay, blood transfusion rate, and times to ambulation and independent stair use were significantly reduced in the corrective group. Postoperatively, Oxford and WOMAC scores significantly decreased in both groups. After surgery, the VAS score was more overtly decreased in the corrective group compared with the standard group.Conclusions: This study concluded that the less invasive short external rotator sparing approach for THA caused less damage, reducing perioperative blood loss, shortening functional recovery time, maintaining prosthesis stability, and improving postoperative pain.

Abstract
Background. Tumors are the second most common cause of death in humans worldwide, second only to cardiovascular and cerebrovascular diseases. Although methods and techniques for the treatment of tumors continue to improve, the effect is not satisfactory. These may lack effective therapeutic targets. This study aimed to evaluate the value of SNHG12 as a biomarker in the prognosis and clinical characteristics of various cancer patients.Methods.We analyzed SNHG12 expression and plotted the survival curves of all cancer samples in the TCGA database using the GEPIA tool. Then, we searched for eligible papers up to April 1, 2019 in databases. Next, the data were extracted from studies examining SNHG12 expression, overall survival and clinicopathological features in patients with malignant tumors. We used Review Manager 5.3 and Stata 15 software to analyze the statistical data.Results.In the TCGA database, abnormally high expression of SNHG12 in tumor samples indicates that the patient has a poor prognosis. Results of meta-analysis is that SNHG12 high expression is related to low overall survival (HR=2.72, 95% CI=1.95-3.8, P<0.00001), high tumor stage (OR=3.94, 95% CI=2.80-5.53, P<0.00001), high grade (OR=2.04, 95% CI=1.18-3.51, P=0.01), distant metastasis (OR=2.20, 95% CI=1.40-3.46, P=0.0006), tumor size (OR=2.79, 95% CI=1.89-4.14, P<0.00001) and lymph node metastasis (OR=2.66, 95%CI=1.65-4.29, P<0.0001).Conclusions.Our study confirmed that the high expression level of SNHG12 is closely related to the clinicopathological characteristics and prognosis of patients and is a new predictive biomarker for various cancer patients.

Published: December 2020

Introduction. Extreme psychrophiles still remain largely understudied. However, they can serve as biological components in drug production, as well as increase the shelf life of food products in food industry. Therefore, the properties of psychrophilic microorganisms are a relevant study object. The present research objective was to isolate new psychrophilic microorganisms in extreme low-temperature conditions of the caves of Gornaya Shoria and Salair (Kemerovo region) and study their antimicrobial properties.
Study objects and methods. The research featured psychrophilic microorganisms isolated in the caves of the Kemerovo region. The sampling was performed in triplicate. The samples were placed in sterile paper. Antibiotic resistance was defined according to the area where the antibiotic plate suppressed bacterial growth. The cell suspension was placed in a Petri dish with an agar-based medium. The discs with antibiotics were put on the surface of the medium and incubated in a thermostat at 28°C for 24 h in order to describe the growth of the isolates.
Results and discussion. The microbial communities of the Gavrilovskaya and Azasskaya caves produced seven isolates with different morphological characteristics. Isolates 1, 4, and 5 had pronounced suppressive properties at 2 ± 4°C. Isolates 1, 4, and 5 proved resistant to antibiotics. Isolate 1 exhibited high resistance (21–26) to Neomycin and Novogramon, medium resistance (17–22) to Ceparin, Kanamycin, Levomycin, Carbenicillin, and Streptomycin, and low (2–8) resistance to Benzylpenicillin and Clotrimazole. Isolate 1 had no antibiotic resistance to Ampicillin, Gentamicin, and Tetracycline. Isolate 4 showed high resistance (22–27) to Novogramon, medium resistance (10–22) to Tetracycline, Clotrimazole, Neomycin, Zeparin, Kanamycin, Levomycin, and Monomycin, and low resistance (2–8) to Ampicillin, Benzylpenicillin, Streptomycin, and Gentamicin. Isolate 4 demonstrated no antibiotic resistance to Carbenicillin and Polymyxin. Isolate 5 proved highly resistant (27–26) to Ceparin, Benzylpenicillin, Levomycetin, and Novogramon, and medium resistant (12–22) to Clotrimazole, Streptomycin, Neomycin, Gentamicin, Polymyxin, Carbenicillin, and Monomycin. Isolate 5 demonstrated no resistance to Ampicillin, Tetracycline, and Kanamycin.
Conclusion. Psychrophiles can serve as microorganisms to create new biological products that suppress the development of diseases in plants. Psychrophiles proved an extremely promising research direction for cultivating and storing agricultural products.

Abstract
The objective of this study is to assess the level of application of integrated water resources management (IWRM) in the lower Oueme valley. In order to achieve this, interviews with the actors' families allowed, on the basis of the survey on indicator 6.5.1 of the Sustainable Development Goals, to represent the degree of implementation of IWRM in the lower Oueme valley using a United Nations (UN) form. The results of this analysis reveal a low level of IWRM implementation with a score of 31 on a scale of 0–100. The weaknesses identified are mainly related to the lack of funding (score of 20/100) to cover all aspects of the development and management of water resources. Inadequate instruments or tools (score of 25/100) to enable decision-makers and users to make rational and informed decisions between different options and action measures, the unfavourable environment (score of 35/100) and finally weak institutional efficiency (score of 45/100), intersectoral coordination, and the involvement of various other stakeholders, are all evils that undermine the efficient management of water resources in the lower valley of Oueme.

Published: December 2020

Abstract
Nigeria is a signatory to the United Nations Sustainable Development Goals (SDGs). Target 6.2 of Goal 6 has requested countries who are parties to the SDGs to end open defecation by 2030. Notwithstanding this, the Government of Nigeria launched a far more ambitious National Road Map in 2016 to end open defecation in the country by 2025. Since water and sanitation are inextricably linked, this paper estimates Nigeria's freshwater requirement to attain open-defecation-free status by 2025. The analysis revealed that the quantity of freshwater required amounted to between 2.74 and 2.94 × 106 cubic metres (m3) per day or between 1.0 and 1.1 × 109 m3 per year under the assumptions made. This amount is relatively less than Nigeria's total water resources potential estimated at 375.1 × 109 m3/year. The data presented will help increase the reliability of estimates of water for sanitation in Nigeria.

Abstract
The Girl Talk initiative, a collaboration of Sesame Workshop, World Vision International and World Vision Zimbabwe, is an innovative project to address gaps in pubertal health and menstrual hygiene education among pre-adolescent and adolescent girls and boys in rural Zimbabwe. Girl Talk uses short animated videos, with accompanying print materials, that use stories about a Zimbabwean school girl, Didi, and her female and male friends growing up and helping each other deal with the challenges they face as they enter puberty. Girl Talk materials are all in the local language, Shona, and are designed to foster conversations among the students and teachers about the experiences of puberty and menstruation that are based on science. The Education Development Center (EDC) and the Zimbabwean firm, NGO Consultancy Africa, were contracted by Sesame Workshop to evaluate Girl Talk. Using a quasi-experimental control-group design with repeated measures to assess the impact of Girl Talk on participating students, the research found a significant impact on participating students’ knowledge about puberty and menstruation compared with the control sample.

Published: December 2020

Abstract
The elimination of diclofenac traces from aqueous environments is important. In this research, the effect of alkaline (NaOH) pretreatment on clinoptilolite before its modification with a surfactant (HDTMA) for diclofenac adsorption under the speculation of the sole presence of diclofenac in the aqueous solution is investigated. The results are compared through isotherm, kinetic, and thermodynamic studies and supplemented by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Brunauer–Emmett–Teller (BET), and the zeta potential analyses. The contact time was investigated in a 0–180-min range. The pH effect was studied in a range of 5–10 because of diclofenac dissociation below pH = 5. The effect of the temperature on diclofenac adsorption was also considered by establishing the experiments at 25, 35, and 45 °C. For HDTMA-modified clinoptilolite, Temkin, and for NaOH-HDTMA-modified clinoptilolite, Dubinin–Radushkevich, and Freundlich isotherm models and in both cases, the pseudo-second-order kinetic model fitted the experimental data best. All the enthalpy and the entropy changes were negative, suggesting exothermic adsorption with a decrease in the degree of freedom of diclofenac anions after the adsorption. Furthermore, diclofenac physisorption was confirmed through isotherm and kinetic studies.
Identification of the actual excess excavation ratio (Stakhanovskaya street – Nizhegorodskaya street site)
Authors: Ter-Martirosyan Armen Z. , Isaev Ilya O. , Almakaeva Anastasia S. 
Published: December 2020

Introduction. Redundant strain arises in buildings and structures in areas of construction work influence caused by the deep bore tunneling performed by tunnel boring machines. The strain analysis must include an excess excavation ratio that depends on the structural features of the shield, the technology of grouting mixture injection outside the lining, the counterweight pressure applied to the shield face and geotechnical conditions so that excessive settlement could be taken account of. The purpose of the article is to identify actual values of the excess excavation ratio to raise excavation and determine the values of standard averaged excess excavation to be further applied in design.
Materials and methods. This paper focuses on tunnel driving between “Stakhanovskaya Street” and “Nizhegorodskaya Street” stations. The project excess excavation ratio was applied pursuant to the regulatory documents in order to perform the analysis using PLAXIS 2D and PLAXIS 3D software packages. The method of sequential iteration was applied to identify the value of excess excavation in line with the actual settlement of buildings and structures obtained by means of monitoring.
Results. The analysis has shown that the actual excess excavation ratio varies between 0.1 and 1.2 % for this construction site which is below the values required by the regulatory documents. As for the 3D setting, the values of actual excess excavation ratios are 2 to 4 times higher than those obtained for the 2D setting, although the value of the actual building settlement remains the same.
Conclusions. Since the actual building settlement is smaller than the projected one, the cost of deep bored tunneling can be reduced by cutting the cost of protection of nearby buildings and structures within the area of tunneling influence without violating any safety requirements and also by reducing the number of buildings withing the projected area of influence, and respectively, by reducing the cost of geodetic monitoring over their displacements.

Published: December 2020

Introduction. Investment value assessment, investment decision making, and successful implementation of investment and construction projects at all stages of their life cycles depend on high-quality feasibility studies focused on budget investments. The purpose of the work is to substantiate budget investments (calculation of the estimated (marginal) cost) by means of modeling and ensuring the compliance between the cost of similar types of work at other construction facilities and requested capacity values or types of work specified in design assignments or preliminary project documentation packages.
Materials and methods. The co-authors analyzed the technical requirements and conditions affecting pre-project solutions (engineering studies), as well as the feasibility and expediency of the project implementation. The calculation of projected (marginal) project costs performed to substantiate budget investments in accordance with established administrative/territorial, organizational, technical and technological pre-design solutions and alternative engineering options, is implemented by means of modeling the costs to be incurred and assignments fulfilled at a similar construction facility.
Results. Budget investments are substantiated by the analysis of the estimated (marginal) cost, performed on the basis of cost parameters and types of works performed at a similar construction facility and with regard for the features and requirements set in the design assignment and pre-project documentation.
Conclusions. The significance of the research project consists in the practical application of the process of modeling the cost of similar construction facilities in the course of compiling a package of documents to substantiate the investments to be made, assess the investment value and make a contribution to investment decision making.

Authors: Burgos Flórez Marco Antonio 
Published: December 2020

El giro dado por Argentina y Brasil hacía gobiernos de derecha, establecen un nuevo escenario para la integración regional, en donde el cambio por una economía más liberal, con perfiles más hegemónicos y menos críticas a la integración regional más profunda y en ámbitos de ampliación del comercio a contextos continentales, le genera un nuevo espacio a profundizar las relaciones con las economías que giran en ámbitos de relaciones hegemónicas y que han tenido un marcado regionalismo abierto como Colombia, México, Chile y Perú.
La crisis del socialismo del Siglo XXI, pone de relieve la pérdida de los espacios para los argumentos anti hegemónicos y las críticas a las relaciones extra latinoamericanas, lo cual aunado a las políticas revisionistas del gobierno norteamericano, generan como lo han manifestado la Comisión Económica para América Latina CEPAL, el Banco Interamericano de desarrollo BID y otros analistas, un nuevo escenario para avanzar en la integración regional, en apoyo a un regionalismo abierto.

Authors: Castillo Alejandro 
Published: December 2020

En la costa pacífica nariñense conviven ancestralmente comunidades afrodescendientes, las comunidades indígenas Awa y Eperara Sapiadara y nuevos grupos poblaciones que dinamizan una relación conflictiva permeada por los saberes propios de las comunidades étnicas y los discursos occidentales de desarrollo del Estado y de las empresas privadas con fines económicos. Desde un enfoque decolonizador, se problematizan las consecuencias de los discursos del desarrollo occidental planteando que las lógicas del extractivismo de la tierra ha producido extractivismo del saber de las comunidades ancestrales. Occidente ha promovidodiscursos de blancura y racionalidad sobre las comunidades étnicas que habitan el territorio.
Se propone la responsabilidad social con el buen vivir de la comunidad, la defensa del territorio y la preservación de los saberes propios es el desafío presente de la etnoeducación. Ante una nación que aún se sigue construyendo, el empoderamiento de las comunidades étnicas implica una autodeterminación de los pueblos que irrumpe en occidente desde sus saberes propios y sus propias formas de ser y de existir.
