Published: January 2022

Layered double hydroxide (LDH) is known as a layered material that can be used as an adsorbent to remove pollutants from aqueous solutions. The use of layered double hydroxide as an adsorbent is not very effective due to its structure which is easily damaged so that it cannot be reused and its small surface area which results in a small adsorption capacity. This can be overcome by developing layered double hydroxide into a composite material. Modification of layered double hydroxide is done by using supporting materials in the form of humic acid and hydrochar. In this study the adsorbent was applied in the removal of Cr(VI) metal from aqueous solutions. The layered double hydroxide modification process was successfully carried out as seen from the XRD, FTIR, and BET analysis. XRD analysis shows the peaks that appear in Mg/Al-AH and Mg/Al-HC are peaks composed of their constituent materials, namely Mg/Al LDH, humic acid, and hydrochar. The vibrations that appear in Mg/Al-AH and Mg/Al-HC are vibrations originating from Mg/Al, humic acid, and hydrochar. The layered double hydroxide material composited with humic acid showed a surface area from 2.155 m2/g to 3.337 m2/g. The layered double hydroxide material composited with hydrochar showed a larger surface area than the Mg/Al LDH base material. The surface area increased 37 times, from 2.155 m2/g to 74.207 m2/g. The Mg/Al-AH composite showed the first adsorption ability of 89.064% and there was no significant decrease in the next cycle. The Mg/Al-HC composite showed adsorption ability in the first cycle which reached 97.079%, the ability to survive up to the fifth cycle with a final ability of 75.029%.
The Impact of the Coronavirus Pandemic on the Resumption of the Conflict in Nagorno-Karabakh
Authors: Khashe J. , Abdollahi M.
Published: January 2022

The Covid‑19 virus pandemic has affected all areas of human life in the past year at three levels: national, regional, and international. The frozen Nagorno-Karabakh conflict was expected to be less intense during the corona pandemic than in previous years. On the contrary, during the coronavirus pandemic, it went through its most stressful period. Moreover, it has entered a new phase in its history with the most casualties and the longest war. In this regard, this article seeks to answer the following question in a descriptive-explanatory manner: “What role has the coronavirus pandemic played in initiating and intensifying the recent conflict in the Karabakh region?”. Therefore, to answer the article’s central question, the authors presented the hypothesis in this way. Although important national and regional factors contributed to the escalation of these tensions, the coronavirus pandemic as a catalyst had a significant impact on the escalation of the Nagorno-Karabakh conflict, which had the highest human cost in the last three decades.
ENVIRONMENTALLY SOUND RESOURCE-SAVING AGROTECHNICAL MEASURES FOR IRRIGATED AGRICULTURE IN THE VOLGA REGION
Authors:   Timirâzevskaâ selʹskohozâjstvennaâ akademiâ, Shadskikh V. A. , Kizhaeva V. E.
Published: January 2022

The article presents the results of research on the conduct of agrotechnical measures in the cultiva-tion of crops on long-term irrigated dark chestnut soils of the Volga region and the impact on their productiv-ity. Resource-saving agrotechnical methods of land use are proposed. An important direction of increasing the efficiency of irrigated lands is to improve the structure of crops: it is advisable to allocate at least 65% for fodder crops, cereals - up to 25%, vegetables, potatoes and industrial crops - 10% of the sown area. When placing crops on the best predecessors, irrigation moisture and effective soil fertility are most productively used, the effectiveness of agromeliorative methods for the cultivation of agricultural crops increases, and their yield increases by an average of 20-25%. The effectiveness of the use of non-moldboard tillage has been proven, since it does not lead to a decrease in crop yields, while it is aimed at preventing negative envi-ronmental processes, such as soil erosion, and saves energy resources. However, for decompaction of the arable horizon, it is advisable to use a multi-depth system of basic tillage. Its depth depends on the level of occurrence of groundwater and their mineralization. It is proposed to carry out the irrigation regime differen-tially, taking into account moisture reserves, especially in soils with a heavy granulometric composition: irri-gation should be avoided after sowing crops, in order to avoid the formation of a soil crust and sparse crops, and the irrigation rates should be set below optimal to prevent runoff.

Un viaje por el tiempo
Authors: Morones Ibarra José Rubén
Published: January 2022

En este artículo se analiza la evolución que ha tenido el concepto tiempo en la ciencia. El tiempo como un concepto elemental que se forma en nuestra mente simplemente como resultado de nuestra existencia, y que nos permite ordenar los acontecimientos, ha resultado ser uno de los más misteriosos y difíciles de comprender. El tiempo lo introdujo Newton en la ciencia como un parámetro absoluto que no resulta afectado por nada, usándolo como un recurso matemático para describir los fenómenos de la naturaleza. Posteriormente, Einstein encontraría que el tiempo no es una cantidad absoluta, sino que depende del observador que lo mida. Actualmente se piensa que el tiempo, que parece que fluye como un continuo, puede ser discreto. Además, es posible que el pasado, que creemos que es algo que dejó de existir, puede ser revisitado con la posibilidad de los viajes en el tiempo.

MEASUREMENT OF THE DETERIORATION OF THE DIESEL ENGINE OIL USING THE IDT CAPACITOR SENSOR
Authors: Lee Sang Hoon , Cho Youn Joung , Sin Tae Ho , Jeon Jae Hyeon
Published: January 2022

A capacitor-type engine oil sensor is designed and fabricated to measure the property of the diesel engine oil depending on the vehicle mileage. This sensor has flat structure with the interdigitated (IDT) electrodes for the smooth oil flow and is constructed using printed circuit board (PCB) for the fabrication convenience. For the increased capacitance, the smaller spacing between the electrodes is preferred and determined with 0.5 mm based on the fabrication limit. The device is applied to actual trucks with diesel engine. From the experiment, the capacitance of vehicle A is initially constant and then increased upto approximately 6,000 km. And then, the output is dramatically decreased, which indicates that the engine oil has been degraded and should be replaced. The interval at which the reduction in capacitance occurs varies depending on each vehicle, which means the exchange interval of engine oil is different from each other. The degree of deterioration of the oil is also measured with the viscosity tests and total acid number (TAN) tests, and the results are compatible with the measurement of capacitance. From these results, it has been confirmed that the fabricated IDT capacitor sensor can measure the engine oil conditions depending on the mileage.
LEGAL DIMENSION OF TRADITIONAL AND COMPLEMENTARY MEDICINE PRACTICES IN TURKEY
Authors: Reva Zeynep
Published: January 2022

Context and Aim: The World Health Organization defines traditional and complementary medicine (TCM) practices as “the sum total of the knowledge, skills, and practices based on the theories, beliefs, and experiences indigenous to different cultures, whether explicable or not, used in the maintenance of health as well as in the prevention, diagnosis, improvement or treatment of physical and mental illness”. This study aims to analyse the main legal regulations on TCM practices in Turkey.

Methodology: The study is based on a systematic review and analysis of desk research and data in the literature. TCM practices were analysed by reviewing the literature screening in particular data of the Ministry of Health, the CAMbrella study which had been conducted by the European Union and the WHO Global Report On Traditional And Complementary Medicine 2019. The literature review was carried out in “Ulakbim Turkish Academic Network and Information Center”, “Google Scholar“. The research was made between September 2021 and October 2021, and 5 keywords were used: “traditional medicine”, “complementary medicine”, "integrative medicine", "alternative medicine" and "functional medicine".

Findings: TCM practices in Turkey are based on the Supplementary Article 13 of the Law No. 1219 on the Practice of Medicine and Medical Arts, Article 9/c and Annex 11 of the Health Services Basic Law No. 3359, and the Presidential Decree No. 1. Traditional and Complementary Medicine Practices Regulation (“Regulation”), dated 2014, stipulates the TCM practices in 15 areas, including acupuncture, apitherapy, phytotherapy, hypnosis, leech, homeopathy, chiropractic, cupping, larva, mesotherapy, prolotherapy, osteopathy, ozone, reflexology and music therapy. Although the regulation basically specified the qualifications of TCM practitioners, the minimum requirements of the practice centres, and in which cases TCM practice can be imply or not, the issues such as the obligation to informed consent regarding TCM practices, medical malpractice regarding TCM practices is not fully regulated. In this respect, it is required to make comprehensive and detailed regulations on these issues.

Conclusion:  TCM practices fill an important gap in terms of human health in areas that modern medicine cannot deal with. It is important to make the necessary legal regulations, especially to regulate informed consent; to define the care standards for medical malpractices regarding TCM practices, to  strengthen the evidence base of TCM practices just like the conventional medicine practices.

Published: January 2022

Diabetic ketoacidosis is a frequent complication of type 1 diabetes mellitus in children and adolescents. One of the leading causes of death in this pathology is cerebral edema. This complication is often asymptomatic, which makes it difficult to diagnose. The main risk factors for cerebral edema in children include the true factors (low partial pressure of carbon dioxide, high blood urea nitrogen, concomitant psychiatric pathology, etc.) and iatrogenic factors (large volume of infusion therapy, rapid decrease in blood glucose levels, administration of bicarbonate, etc.). The pathophysiology of this complication is not yet fully understood. The main pathophysiological elements of cerebral edema in children with DKA include the disruption of blood-brain barrier permeability, edema of brain cells, and dysfunction of cell membranes. Important roles are also played by hypercapnia and reduction of osmotic pressure. Based on the character of pathophysiologic changes, cerebral edema in children and adolescents with DKA is subdivided into vasogenic and cytotoxic. Gaining a better understanding of the pathophysiological mechanisms of this complication will increase the quality of care provided in pediatric practice.
