THE PROTO-IRANIAN CORE OF THE OSSETIAN EPIC TRADITION (DRAGON-FIGHTING PLOT)
Authors: Салбиев Т.К. 
Published: August 2021

В статье предпринимается попытка реконструкции драконоборческого сюжета осетинской Нартиады как важнейшего условия решения проблемы ee происхождения. Впервые эта задача решается с привлечением персидского материала, обеспечивающего успешное восстановление искомого общеиранского эпического ядра. Обращение к сюжету из Шах-наме о восстании кузнеца Каве позволяет установить важнейший социально-исторический параметр этого сюжета, а именно, царскую инвеституру, а также выявить два производных от него основных характерных атрибута: знамя из шкуры быка и быкоголовую палицу. В свою очередь эти конститутивные особенности сюжета делают главным героем не нарта Батрадза, как было принято считать до сих пор, а тех нартов, которые не только обладают названными царскими регалиями, но и выступают в роли первого нарта . Таковыми оказываются нарт Сауасса и пара Уархтанага / Уархага. В конечном счете, удается привести к общему знаменателю две основных версии индоевропейского происхождения Нартиады. Первая из них опирается на трехфункциональную теорию Ж. Дюмезиля, и вторая, выдвинутая В. В. Ивановым и В. Н. Топоровым, на сюжет о поединке героя с чудовищем.
The article attempts to reconstruct the dragon-fighting plot of the Ossetian Nart epics, as the most important condition for solving the problem of the origin of Nartiade. For the first time, this problem is solved with the help of Persian material, which ensures the successful restoration of the sought-after Proto-Iranian epic core. The investigation of the plot from Shah-Nameh about the uprising of the blacksmith Kava allows us to establish the most important socio-historical parameters of this plot, namely, the royal investiture, as well as to reveal two main characteristic attributes derived from it: a banner made from the skin of a bull and a bull-headed club. In their turn, these constitutive features of the plot do not allow Batradz to be considered the main hero, as was commonly believed, but to switch on to those heroes that do not only possess the named royal regalia, but also act as the first Nart . These include Sawassa and twin brothers Warxtanag and Warxag. In the long run, it seems possible to bring to a common ground two main versions of the Indo-European origin of Nartiade. The first of them is based on the three-functional theory of G. Dumzil, and the second, put forward by V. V. Ivanov and V. N. Toporov, is based on the plot of a hero fighting with a monster.

Published: August 2021

Выявлена взаимосвязь между наркопреступностью и уровнем общей пре- ступности, между распространением наркомании и инфекционными заболеваниями, в том числе СПИДом, гепатитами и т. д. Определены географические факторы нарко- преступности рассчитана динамика преступлений в сфере незаконного оборота нар- котиков в России за 19902015 гг. выявлены основные направления наркотрафиков и территориальная дифференциация наркопреступности в стране. Определено, что одним из главных факторов бурного роста наркопреступности в стране стало формирование и становление Северного маршрута наркотрафика из Афганистана. Развитию Северного маршрута благоприятствовало наличие прозрачных границ с Казах- станом и странами Центральной Азии. Северный маршрут изначально ориентировался как наркотрафик через Россию в Европу, однако постепенно стал наркотрафиком в Россию. Таким образом, Россия стала самой героинопотребляющей страной в мире. Установлено, что самый высокий уровень наркопреступлений наблюдается либо в регионах, находящихся на наркотрафиках, либо в регионах поставщиках наркотиков, либо в богатых регионах. Определено, что постепенно меняется структура потребления наркотиков. Выявлен устойчивый тренд с запада на восток: с движением в этом направлении уровень наркопреступности постепенно повышается.
The correlation between drug-related crime and the level of general criminality, between the spread of drug abuse and infectious diseases, including AIDS, hepatitis, etc., is revealed. The geographical factors of drug crime are determined the dynamics of crimes in the sphere of illicit drug traffi cking in Russia for 1990-2015 is calculated the main directions of drug traffi cking and territorial differentiation of drug crime in the country are identifi ed. It is determined that one of the main factors of the rapid growth of drug crime in the country was the formation of the Northern Route of drug traffi cking from Afghanistan. The development of the Northern Route was favored by the presence of transparent borders with Kazakhstan and the countries of Central Asia. The Northern Route was originally oriented as drug traffi cking route through Russia to Europe, but gradually became drug traffi cking route to Russia. Thus, Russia has become the most drug addicted country in the world. It is established that the highest level of drug crimes is observed either in the regions that are situated on drug traffi c routes, or in regions - drug suppliers, or in rich regions. It is determined that the structure of drug consumption is gradually changing. A stable trend has been identifi ed from west to east: the level of drug crime is gradually increasing with the movement in this direction.
Stress-echocardiography or coronary computed tomography in suspected chronic coronary syndrome after the 2019 European Guidelines? A practical guide

Published: August 2021

Stress-echocardiography can rightly be considered one of the champions of cardiac functional imaging, thanks to its real-time imaging, high temporal resolution, high safety and very low cost. When stress-echocardiography is performed at top technical quality, hence taking advantage of ultrasound contrast media for endocardial border delineation at least for suboptimal cases, subjectivity is minimized, and with the routine use of coronary flow reserve measurement (left anterior descending coronary artery, stress/rest ratio reduced or normal, i.e. <>2.0) diagnostic sensitivity is strengthened.
The true competitor of any type of functional imaging, stress-echocardiography included, is nowadays coronary computed tomography angiography, which is instead a diagnostic method directly, noninvasively assessing coronary anatomy, apparently the holy grail for any cardiologist. The new 2019 Guidelines on chronic coronary syndrome of the European Society of Cardiology change the existing landscape and clinical practice, while they probably cannot clarify which type of test, functional or anatomic, should be first chosen in different clinical scenarios of suspected chronic coronary syndrome.
We review the existing data and the authors’ personal view in order to assess how functional stress-echocardiography compares with coronary computed tomography angiography regarding three main aspects: diagnosis of coronary artery disease, guidance of therapy (coronary revascularization versus medical therapy) and risk stratification.

Published: August 2021

Chromium oxide (Cr2O3) doped ZnO nanoparticles were prepared by pulsed laser deposition (PLD) technique at different concentration ratios (0, 3, 5, 7 and 9 wt %) of ZnO on glass substrate. The effects of ZnO dopant on the average crystallite size of the synthesized nanoparticles was examined By X-ray diffraction. The morphological features were detected using atomic force microscopy (AFM). The optical band gap value was observed to range between 2.78 to 2.50 eV by UV-Vis absorption spectroscopy, with longer wavelength shifted in comparison with that of the bulk Cr2O3 (~3eV). Gas sensitivity, response, and recovery times of the sensor in the presence of NH3 gas were studied and discussed. In the present work, we found that the sensitivity was increased upon increasing the concentration ratio from 3 to 5%wt of ZnO, whereas it was decreased again over that value. Also, we found that the sensitivity was increased when increasing operating temperature, while the response time was decreased. The optimum concentrations ratio for NH3 gas sensitivity at 5%wt ZnO revealed sensitivity of 66.67% and response time of 14s at operating temperature of 300oC and 700mJ PLD energy.

This study was achieved to satisfy two goals, the first of which is to treat an environmental problem represented by the disposal of date seeds, and the second is the use of these wastes to improve some mechanical and thermal properties of poly methyl methacrylate PMMA through strengthening different proportions of the powder of date seeds.
Particles of date seeds were used as a natural strengthening material for PMMA polymer, by mixing the matrix material (resin) with the hardener while still stirring continuously for a period of 10 min. After that, the samples of the reinforced material were prepared by adding the powder of date seeds, which is the reinforcing substance, with different percentages of weight fraction (0, 0.5, 1, 2, 3, 5 wt. %) and a grain size of <75 µm, while continuing to stir (10 min) for a second time. The composite samples were prepared by the Hand-Lay-up method and cut according to the standard ASTM. Thermal conductivity and some mechanical properties, such as impact strength, tensile strength, compressive strength, flexural strength, and hardness, were studied. An improvement was found in all properties at the reinforcement rate of 1-2 wt. %.

Authors: Mildawani Irina , Rahman Arief 
Published: August 2021

The COVID-19 pandemic in 2020 affected countries across the world and sudden disruptions to everyday life and impact well-being. The implementation of exceptional procedures of social distancing includes working places and schools’ closures urged people to stay at home to reduce the number of close physical interactions and decrease the spreading of pandemic. With the long hours of family members staying at home, people prefer to do some activities at home. Doing gardening is seen as one of the preferences of urban inhabitants. However, few studies have measured the preference of urban gardening, particularly during household gardening in Jabodetabek, Indonesia. This paper examines people preferences on household gardening during the pandemic of Covid-19, comparing it with their activities before and predict it with possibility after the pandemic. We explore how type of gardening varies between vegetable or ornamental plants, community or household garden type, and the persons involved during gardening. Using google form, 148 respondents in Jabodetabek were answering between July-Dec 2020. Our study examines the emotional well-being (EWB) using Qualitative Content Analysis (QCA), applying codes and categories. Gardening as one of the favorable activities considered to generate happy time with family and they would like to continue the activities after the pandemic. However, landscape architect was not yet chosen as the gardener when they need professional assistance. This might rise a future research about the role of landscape architect in gardening movement in urban community gardening
Protective effects of lycopene against adenine-induced chronic renal failure in rats
Authors: Gori Pooja , Patel Alkesh , Solanki Nilay , Shah Umang , Patel Veena , Patel Sandip 
Published: August 2021

Objectives:
Chronic renal failure (CRF) is a public health concern in both developed and developing countries. Therefore, there is still a need to look for secure and successful agents that can either minimise or prevent CRF from advancing to end-stage renal disorder. This study aimed to assess the effect of lycopene on adenine-induced CRF in the rat.

Materials and Methods:
Animals were divided into five groups (n = 6). Normal control group received normal vehicle, disease control group received orally adenine (50 mg/kg/day), L 100 group received orally lycopene (100 mg/kg/day) + adenine (50 mg/kg/day), L 200 group received orally lycopene (200 mg/kg/day) + adenine (50 mg/kg/day) and L 400 group received orally lycopene (400 mg/kg/day) + adenine (50 mg/kg/day) for 30 days.

Results:
Compared to the control group, the disease control group had decreased bodyweight, food intake and also increased the relative kidney weight and urine output. Adenine-treated group also significantly increased the blood urea nitrogen, serum creatinine, phosphorus, alkaline phosphatase, uric acid, magnesium and reduced the calcium, urine creatinine and urine urea nitrogen. Besides, adenine also gave a positive test of serum C-reactive protein and proteinuria. Histopathologically, adenine caused significant inflammatory changes to renal tissues compared with the normal control group. When administered concomitantly with adenine, lycopene alleviated all the measured adenine-induced physiological, biochemical and histological changes.

Conclusion:
We concluded from this analysis that oral lycopene administration could potentially mitigate the adverse effect of CRF that might be due to their antioxidant and free radical scavenging properties.

Authors: Kala Niranjan , Pal Sushma , Sharma Sachin Kumar , Telles Shirley , Balkrishna Acharya 
Published: August 2021

Objectives:
The present study compared yoga practitioners with age- and gender-matched yoga naïve persons on performance in a mirror tracing task which involved tracing a star pattern on a sheet of paper while looking at its reflection in a mirror.

Materials and Methods:
The present cross-sectional study included twenty yoga practitioners of both sexes (15 females; group mean age ± SD; 24.8 ± 3.4 years) and twenty yoga naïve persons (15 females; group mean age ± SD; 24.2 ± 3.8 years) of the same age range. Both groups were assessed for performance in the mirror tracing task in three trials. The distance covered, total errors, and time taken to complete the task were noted.

Results:
Yoga practitioners made significantly less errors (P < 0.05) in the third trial and covered greater distance in star tracing in the first (P < 0.05) and second (P < 0.05) trials compared to yoga naïve participants. Mann– Whitney U-test was used for all comparisons.

Conclusion:
Yoga practice may be useful to facilitate learning in the tasks that require better perceptual and motor skills.
Immediate changes in cardiac autonomic tone and stroke volume during microgravity simulation using head-down tilt
Authors: Shankhwar Vishwajeet , Singh Dilbag , Deepak K. K. 
Published: August 2021

Objectives:
Gravity plays an important role in the day-to-day functioning of the cardiovascular system (CVS) in the human body. The absence of gravity severely affects CVS functioning. Out of existing simulation models of microgravity, the 6° head-down tilt (HDT) is frequently used analog to replicate the physiological effects of microgravity on earth.

Materials and Methods:
The present study has been designed to determine the specificity of 6° HDT usage as a microgravity simulation. The heart rate variability (HRV), blood pressure (BP), cardiac output (CO), and stroke volume (SV) responses to 5 min exposures were investigated for 4°, 6°, and 8° HDT. It was hypothesized that the graded HDT around 6° will demonstrate reversal of autonomic parameters. The study was conducted on 28 male subjects aged 20–30 years.

Results:
The study reveals that there was a significant rise in diastolic and mean BP at 6° and 8° HDT as compared to baseline. It was also observed that the high-frequency power in HRV was increased at 6° HDT (P = 0.026), with a concomitant reduction in the low-frequency power (P = 0.03) of HRV. The CO was increased at 6° and 8° HDT as compared to baseline (P = 0.037 and 0.021, respectively). There were no significant changes observed in any of the recorded parameters at 4° HDT. The cardiopulmonary volume receptors might have sensed the blood volume change in HDT as in microgravity simulation the blood passively shifts to cephalad. To overcome the low blood volume problem, the heart tried to pump extra blood through increased CO. At 8° HDT, it was observed that the cardiac sympathetic activity and CO were increased, which is not observed during microgravity exposures.

Conclusion:
The study suggests that 6° head-down-tilt is the best tilt level for producing microgravity on earth to study immediate cardiovascular parameters as it is a balanced compromise of increased vagal activity and CO without activation of cardiac sympathetic activity. Therefore, our data provide physiological evidence in support of 6° HDT microgravity simulation for the study of immediate cardiovascular responses.

Authors: Veena C. N. , Kamath Rashmitha Vinayak , Kumar M. Prashanth 
Published: August 2021

Objectives:
The concept of neuronal plasticity has been considerably studied to know how long-lasting changes are associated with brain’s capacity to be shaped or sculptured by experience. Potential cognitive benefits of abacus training have been proved by various studies indicating it to be a promising tool in improving cognitive abilities including arithmetic abilities, visuospatial and working memory. Critical flicker fusion happens when the individual can no longer differentiate between changing visual stimuli. It can be modulated by behavioural or psychophysical techniques. The objectives of the study were to evaluate the effects of abacus training on critical flicker fusion frequency (CFFF) threshold.

Materials and Methods:
CFFF threshold (CFFFT) was measured in 60 school students studying third and fourth standard (30 trained in abacus and 30 not trained in abacus) using portable software-based apparatus.

Results:
The mean scores of abacus trained individuals were significantly higher compared to those who were not trained.

Conclusion:
Since higher CFFFTs can absorb more visual information, increasing their threshold might lead to cognitive improvement and better academic performance. Abacus trained individuals showed significantly higher critical fusion frequency threshold.

Ship sanitation and its environment are a mandate from International Health Regulation (IHR)2005 and the regulation of Ministry of Health Republic IndonesiaNo 40 Tahun 2015 that request all the ship in Indonesia territory should have a certificate of ship sanitation. This is due to prevent, protect and control spreading of diseases. This study aimed to analyze the sanitation condition of cargo ships in working area of Harbour Health Office (KKP) type III Manokwari. Research location was done in Manokwari Harbour on September to October 2020. Method used in this study was descriptive approach and direct observation. Sample was obtained by purposive sampling, that 13 (thirteen) cargo ships anchored in Manokwari. Variables observed included room sanitation, vector, foods and drinking water, and waste. Results showed that in general the sanitation of the 13 cargo ships was qualified good (91.21%), except for warehouse and medical facilitation. There were two ships (15.38%) unqualified because had no storage room for dry and wet foods. Moreover, six cargo ships (46.15%) had no medical facilitation according to the requirement, but only some medicines without observation room and medical tools. On the other hands, the vector and disease-spread animals, management food and drinking water, as well as the waste management for 13 cargo ships were qualified.
