Authors: Makarov Sergey , Rodin Sergey , Kuznetsova Irina , Chudetsky Anton , Tsaregradskaya Svetlana
Published: October 2021

Introduction. Forest berry plants are popular on the food market and in pharmacy for their high nutritional and medicinal value. Plantations of forest berry plants can proliferate on unused lands, including depleted peatlands. Clonal micropropagation is the most effective method for obtaining large quantities of high quality planting material. Light-emitting diodes are highly effective for clonal micropropagation. The research objective was to study the effect of different spectral ranges on the process of root formation of forest berry plants in vitro. Study objects and methods. The research featured regenerant plants of half-highbush blueberry, arctic bramble, American cranberry, European cranberry, lingonberry, and Kamchatka bilberry of different cultivars. A set of experiments made it possible to study the effect of lighting type on the growth and development of the root system of forest berry plants in vitro using white fluorescent lamps, white spectrum LED lamps, and LED lamps with a combination of white, red, and blue spectra at the in vitro rooting stage of clonal micropropagation. Results and its discussion. The largest number (3.4–14.6 pcs.) and the maximum total length (10.0–156.9 cm) of roots were observed under LED lamps with a combination of white, red, and blue spectra. The effect was by 1.1–2.8 and 2.0–4.5 times higher than in the case of white-spectrum LED lamps, and by 2.3–7.0 and 3.3–14.9 times than in the case of fluorescent lamps. Variety and shape proved to have no significant effect on biometric indicators. Conclusion. LED lamps had a positive effect on the process of rhizogenesis of forest berry plants during clonal micropropagation. They appeared to be more effective than fluorescent lamps. The combination of white, blue, and red spectra increased the biometric parameters of plants at the stage of in vitro rooting.

Authors: El'gart Elena , Holodceva Elena , Kameneva Veronika , Sergeeva Anna
Published: October 2021

The article introduces a methodological approach to teaching English as a second language (ESL) to schoolchildren with general speech underdevelopment and identifies the main interlingual influences. The research featured various means that optimize the English language acquisition by schoolchildren with general speech underdevelopment. The research objective was to identify and substantiate the optimal methodological tools that take into account interlanguage influences. The study revealed the causes of the poor native grammar skills in this group of schoolchildren. A longitudinal study of interlingual influences made it possible to define several methodological tools that are able to improve the process of ESL acquisition by schoolchildren with general speech underdevelopment. These tools take into account the native vocabulary skills in children of this category. The authors propose to create additional adapted ESL syllabuses for schoolchildren with general speech underdevelopment. Such programs should be based on the peculiarities of the native vocabulary and grammar development in this category of children.
Debatable Issues of Law Enforcement Practice on Reducing the Penalty by the Court in Accordance with Article 333 of the Civil Code of the Russian Federation
Authors: Abakumova Ekaterina
Published: October 2021

This study is an attempt to draw a theoretical and legal understanding of law enforcement practice to reduce the penalty in court. The research was based on the comparative legal, statistical, historical, and general scientific methods of cognition (system method, analysis and synthesis, logic, etc.). The author analyzed doctrinal ideas regarding the legal nature of penalty. The study revealed controversial conceptual and theoretical issues related to this legal institution that are of fundamental importance for its practical implementation. A retrospective analysis of the law enforcement practice under Article 333 of the Civil Code of the Russian Federation demonstrated a need for a wider recognition of the penalty function, not only in civil law, but also in tax relations.
Private vs. Public Principles in the Regulation of Physical Culture and Sports Relations
Authors: Kovalenko Ekaterina , Tydykova Nadezhda
Published: October 2021

The research objective was to find the optimal ratio of private and public principles in the regulation of physical culture and sports relations. The authors used the method of induction to analyze the general approaches to the essence of private and public principles in the modern theory of law. At the present stage, their optimal balance is necessary. The systemic-structural method made it possible to present private and public aspects through their specific manifestations, i.e. institutions of responsibility, control, and partnership. The methods of critical analysis were used to question some of the official positions regarding the institution of public and private partnership and the strengthening of criminal liability. The comparative legal method demonstrated the similarities between the ongoing processes in the sports law abroad and in Russia. The public principles in the regulation of sports relations need to be expanded by expanding the scope of social functions of the state. Some specific cases provided a positive assessment of the increase in the private law mechanisms in terms of the relative autonomy of various sports and the development of the institution of public and private partnership. An appropriate legislative framework would guarantee the rights and legitimate interests of private investors and help the state to achieve socially significant goals. The research results can expand the scientific understanding of sports law and serve as material for lawmaking. Thus, the balance of private and public principles in the regulation of physical culture and sports relations is in the shift of the role of the state from control towards the expansion of obligations to implement its social function. However, the expanding scope of private methods, which is natural for this stage, requires restrictions.
Participation of Employees of the Penitentiary System as a Condition for Illegal Drug Trafficking in Prisons
Authors: Serezhkina Mariya
Published: October 2021

The research featured the causes of drug traffic in prisons. The hypothesis is that this crime would be impossible without the participation of employees of the Federal Penitentiary Service. The paper introduces an analysis of statistical data on drug trafficking in Russian prisons. The statistics showed that the level of drug trafficking in prisons remains stable for the last five years, despite the ongoing anti-drug policy of the state, which confirms the abovementioned hypothesis. The study highlighted the role of an employee of the Federal Penitentiary Service in various types of criminal activities related to drug trafficking in prisons. The author analyzed the legal practice of qualifying the actions of prison employees in the field of drug trafficking during their official duties and proposed to introduce uniformity in the qualification of these actions. The paper contains a comparative analysis of a Criminal Investigation Department employee engaged in drug trafficking and a citizen involved in the same crime outside the Criminal Investigation Department. The composition of crimes related to drug trafficking needs an additional qualifying feature for employees of the Federal Penitentiary Service.

Published: October 2021

Abstract This paper presents a discussion of conceptual art in terms of new media and technology. The author aims to highlight the interplay of technology and new media with conceptual art. In conceptual art, the idea or concept behind the work is as important as the work itself. In these ways, new media is a blend of various media juxtaposed with enticing thoughts and ideas. Taking an essential step in that direction, technology has been a significant player in the global impact of 21st-century artists from India. Interestingly, artists used electronic technology to broadened their ways and expressed their ideas conceptually based. Technological development giving rise as well as generate creative visual forms. “In conceptual art, the idea or concept is the most important aspect of the work…the idea becomes a machine that makes the art”. In this way, both conceptual Art and Technology are much more closely related. The author further exemplifies the contemporary artists work in India at the intersection of conceptual Art, Technology, and new media art. Therefore, using secondary data and descriptive research methodology, this paper re-examines conceptual Art, new media, and Technology to promote dialogue and creative expression and address social change. By interpreting conceptual art in terms of media and technology, the author concludes that these tendencies share significant similarities, and that is a beneficial and innovative sight in the contemporary art scene in India. Technology is shown to have a significant influence on conceptual art but often based on historical, social and cybernetic narratives.

Published: October 2021

The present study shows the investigation of variables causing waste in the pattern making process through the examination of common methods of skirt design to ensure the optimal arrangement. Hence, efficiency is boosted during the pattern making phase by removing such variables. In this regard, it is proved the idea of making different skirts designs in the zero-waste approach without changing the skirt design structure. Moreover, the weight of pattern wastepaper is calculated after separating the garment parts from the main layout to evaluate the effect of creating a design regarding waste reduction. The study shows while maintaining the skirt design structure and using the standard pattern methods, appropriate changes are needed for a creative style of skirt design. The results can be used as a guideline to pattern makers and manufacturers for more objective selection and to support the development of zero-waste pattern making methods.

Published: October 2021

Understanding the details of the water-flow hazard (WH) to workers in water disasters is extremely important in disaster-risk management. This paper aims to develop a numerical assessment model for the WH affecting worker safety. An assessment model of WH is proposed for water disasters in the underground mine, which includes two characteristics: (a) from water-disaster environment to WH of workers and (b) from multiple influencing factors to quantitative comprehensive quantification. To verify the feasibility of WH, it is applied to a water disaster in an underground coal mine. The simulation results highlight that the WH model can assess the hazard value of worker-1 (m = 72 kg, H = 1.72 m) at paragraph – 6134 and paragraph – 8840 of roadway, with different water-flow conditions, in the whole time of the disaster. Meanwhile, the differences between WH for three workers, worker-1, worker-2 (m = 95 kg, H = 1.82 m), and worker-3 (m = 60 kg, H = 1.62 m), under the same flow conditions are provided by the curve. Moreover, dynamic visualization of WH is achieved, which shows how the hazard of worker-1 changes into the time of 2, 5, 11, 19, and 27 h after a disaster in the full mine. Therefore, this numerical assessment can be used to evaluate the hazards posed by water flow to workers, which meets the urgent demands of water-disaster management for underground mines.
Impacts of urbanization and climate change on water quantity and quality in the Carp River watershed

Published: October 2021

Pressure on water resources has reached unprecedented levels during the last decades because of climate change, industrialization, and population growth. As a result, vulnerability to inappropriate water availability and/or quality is increasing worldwide. In this paper, a Soil & Water Assessment Tool (SWAT) model of the Carp River watershed located in the city of Ottawa, Ontario was calibrated and validated. The model was then used to evaluate the individual and coupled impacts of urbanization and climate change on water quantity (discharge) and quality (nitrogen and phosphorus loads). While most of the watershed is currently rural, the headwaters will undergo rapid urbanization in the future, and there are concerns about possible negative impacts on water quantity and quality. Seven scenarios were developed to represent various watershed configurations in terms of land use and climate regime. Future climate time series were obtained by statistically downscaling the outputs of nine regional climate models, run under representative concentration pathways (RCP)4.5 and RCP8.5. The impacts were evaluated at the main outlet and at the outlet of an upstream sub-watershed that would be most affected by urbanization. Results show that climate change and urbanization's impacts vary greatly depending on the spatial scale and geographic location. Globally, the annual average discharge will increase between 6.75 and 9.34% by 2050, while changes in annual average nitrogen and phosphorus loads will vary between −1.20 and 24.84%, and 19.15 and 23.81%, respectively. Local impacts in sub-watersheds undergoing rapid urbanization would be often much larger than watershed-scale impacts.

Authors: Chaudhary Rakesh Kumar , Ahmad Zulfequar , Mishra Surendra Kumar
Published: October 2021

Experiments were performed over smooth and corrugated aprons with different corrugation dimensions to study the scour and flow characteristics under submerged wall jets condition. The scour depth and length are significantly lower for corrugated than smooth rigid aprons. The maximum reductions in scour depth and length are 79 and 83%, respectively. Optimum scour depth and length are found for aspect ratio (ratio of corrugation wave length to amplitude) three for corrugated apron. The factors affecting scour depth and length were analyzed graphically, and empirical equations are proposed for predicting maximum scour depth and length, and the point of maximum scour depth for corrugated aprons. Velocity, turbulence characteristics, and Reynolds stress in scour holes for smooth and corrugated aprons were also studied.
Hydrological peaks evaluation at Chitral and Tarbela stations, Pakistan, using combined Bayesian regularized neural network and signal difference average based variational mode decomposition method: A case study
Authors: Khan Mehwish Shafi , Hassan Syed Ahmad
Published: October 2021

Pakistan, being an agricultural country, highly depends on its natural water resources which originate from the upper regions of Hindu Kush-Karakoram-Himalaya Mountains and nourish one of the world's largest Indus Basin irrigation systems. This paper presents streamflow modelling and forecasting using signal difference average (SDA) based variational mode decomposition (VMD) combined with machine learning (ML) methods at Chitral and Tarbela stations on the Indus River network. For this purpose, VMD based random forest (VMD-RF), gradient boosting machine (VMD-GBM) and Bayesian regularized neural network (VMD-BRNN) have been chosen. Moreover, traditional time series flow models, that is seasonal autoregressive integrated moving average (SARIMA) and classical decomposition approach with particle swarm optimization-based support vector regression (PSO-SVR), are considered as benchmark models for comparison. The results show that overall, VMD-BRNN performed best, followed by VMD-GBM and VMD-RF, whereas SARIMA and PSO-SVR ranked last. Overall, SARIMA and PSO-SVR are failing to capture most of the peaks even during the training period whereas hybridization of VMD and ML methods has shown increased robustness of the models. The results show that the influential role of the high dimensional components and robustness on the river flow may be explored by most optimum SDA based VMD signals hybrid with BRNN method.

Published: October 2021

Most residents in developing countries suffer severe water shortage and often resort to self-supply. Unfortunately, some self-supply water sources contain disease-causing biological and chemical contaminants and require point-of-use (POU) treatment. However, recontamination and persistence of chemical contaminants occur, which defeats the aim of POU. This study aims to develop an affordable low-technology system that effectively treats whole-house water sourced from borehole and rain without recontamination. Raw borehole water (RBW) was treated with KAl(SO4)2·12H2O (8.10 mg/L), Ca(OH)2 (68.21 mg/L) and NaOCl (1.875 mg/L) in two separate tanks and thereafter filtered through 5-micron and 0.5-micron carbon filters, and a reverse osmosis system. The results showed that heterotrophic plate count (2,700 CFU/mL) and total coliform (378.00±21.25 MPN/100 mL) in RBW were reduced to zero, and total hardness was reduced by >83% after treatment and there was no recontamination. Chromium (0.05±0.002 mg/L), Cu (0.04±0.001 mg/L), Pb (0.09±0.001 mg/L), Fe (0.26±0.005 mg/L) and Mn (0.2±0.001 mg/L) in the RBW were reduced below detectable limits after treatment. The annual per capita cost of water treatment was estimated at N 4,744.44 ($9.32) at per capita consumption of 100 L/day. Our technology shows exceptional promise in providing affordable and safe water to the entire household throughout the year.

Authors: Yang Ling , Wang Lin
Published: October 2021

With the quick development of social economy, the sharp contradiction between supply and demand of urban water resources is becoming much more obvious. Comprehensive assessment of urban water resources carrying capacity is of great significance to urban sustainable development planning. In this study, the urban water resources carrying capacity of Qingdao based on basin unit over 2010–2030 is predicted using analytic hierarchy process and system dynamics method. The results showed that the total water demand of all the nine basins have an upward annual trend from 2017 to 2030, among which the domestic water consumption increase obviously. The urban water resource carrying capacity indexes in all basins over 2017–2030 show a downward annual trend under the current social development model. So it is urgent to improve the water resource carrying capacity of each river basin by means of industrial structure optimization and upgrading and active development of new water sources.
EMPLOYMENT OF YOUTH AND OLDER PEOPLE IN THE LABOR MARKET OF THE TYUMEN REGION: ANALYSIS BASED ON MICRODATA
Authors: SHMUNK Daria Yu. , GILTMAN Marina A.
Published: October 2021

The unfavorable demographic trends of an aging population are leading to a reduction in the size of the labor force and its structural changes. Young people and older people are the most vulnerable applicants for employment in the labor market. The economic behavior of young people and older people is still insufficiently studied at the regional level. This study analyzes the situation within the region. For instance, the Tyumen region without autonomous okrugs was selected, as a region characterized by a stable situation on the labor market with a fairly diversified structure of the economy (therefore, the study did not include the northern autonomous okrugs). Microdata of a sample survey of the labor force of the Federal State Statistics Service were used as a basis for the analysis. Using binary logit models, the probabilities of being employed in the Tyumen region at the age of 20 29 and 55-64 are estimated, taking into account the type of settlement and the individual characteristics of the employee. Estimates are given for the Tyumen region and Russia for 2010, 2015 and 2019.The results showed that the greatest contribution to the probability of employment is made by education (higher, secondary and primary vocational) and young age, which is especially typical for the Tyumen region. Men are more likely to be employed both in the region and in the rest of the country than women. Living in a city in 2010 and 2015 reduced the likelihood of employment in the Tyumen region, in 2019 it increased. For the rest of Russia, the marginal effects (slope coefficients) for the variable of urban residence in all years were small but positive.

Published: October 2021

The development of effective technologies to cope with persistent and progressive global
problems in human health and sustainable development has become an imperative worldwide
challenge. The search for natural alternatives has led to the discovery of bacteriocins, which are potent
protein antimicrobial compounds produced by most bacteria. The relevance of these molecules
is evidenced by more than 4,500 papers published in the last decade in Scopus indexed journals
highlighting their versatility and potential to impact various aspects of daily life, including the food
industry, medicine, and agriculture. Bacteriocins have demonstrated antibacterial, antifungal, antiviral,
and anticancer activities, and they also act as microbiota regulators and plant growth promoters.
This mini-review aims to provide insights into the current state and emerging roles of bacteriocins,
as well as their potential and limitations as feasible solutions against current diverse global
problems.

Iodoacetate Induced Osteoarthritis
Authors: Chen Rilan , Zhang Xiaoyun , Liao Zilong , Zhu Ying , Chen Yueping , Liu Jianhang , Chen Xia
Published: October 2021

Background:

Osteoarthritis (OA) is a degenerative joint disease with an increasing incidence
associated with increased life expectancy. The application of traditional Chinese medicine in
the treatment of OA has become a research hotspot.

Objective:

This study investigated the effects of XGS externally applied to osteoarthritic joints and
analyze its effect on pain in monosodium iodoacetate (MIA)-induced OA rats. This study also
evaluates potential mechanisms behind the anti-osteoarthritic effects of XGS.

Methods:

A total of 24 Sprague Dawley rats were evenly and randomly divided into three separate
groups, including the normal control (NC), OA and XGS groups. MIA (50 μL, 10 mg/mL) was injected
into the left knee joints of the rats to induce OA. After 7 days, The rats of XGS group were
given XGS (0.45 g) that was externally applied to the left knee joint, were fixed with gauze, and
continuously administered XGS for 28 days. Morphological changes in tissues and organs were
examined using H&E staining. Biochemical indicators were measured using an automatic biochemical
analyzer. Inflammatory cytokines were detected using ELISA kits and immunohistochemistry.
RNA-based high-throughput sequencing (RNA-seq) was performed to detect differential
expression of mRNAs in normal and MIA–induced OA rats.

Results:

Stride of the left leg was extended in rats, matrix increased on cartilage tissue surfaces,
and inflammatory cytokines were reduced when treated with XGS. RNA-seq results revealed that
the PI3K-Akt signaling pathway is activated in the OA model. The qRT-PCR showed that the expression
levels of Tnn, Col6a6, Igf1 and Lamb1 were up-regulated by XGS.

Conclusions:

Altogether, this work demonstrated the potential therapeutic effects of XGS in rats
with OA induced by MIA. The XGS may be considered an alternative therapy to manage OA.

Published: October 2021

Background

Basic studies suggest that statins as add-on therapy may benefit patients with COVID-19; however, real-world evidence of such a beneficial association is lacking.

Objective

We investigated differences in SARS-CoV-2 test positivity and clinical outcomes of COVID-19 (composite endpoint: admission to intensive care unit, invasive ventilation, or death) between statin users and nonusers.

Methods

Two independent population-based cohorts were analyzed, and we investigated the differences in SARS-CoV-2 test positivity and severe clinical outcomes of COVID-19, such as admission to the intensive care unit, invasive ventilation, or death, between statin users and nonusers. One group comprised an unmatched cohort of 214,207 patients who underwent SARS-CoV-2 testing from the Global Research Collaboration Project (GRCP)-COVID cohort, and the other group comprised an unmatched cohort of 74,866 patients who underwent SARS-CoV-2 testing from the National Health Insurance Service (NHIS)-COVID cohort.

Results

The GRCP-COVID cohort with propensity score matching had 29,701 statin users and 29,701 matched nonusers. The SARS-CoV-2 test positivity rate was not associated with statin use (statin users, 2.82% [837/29,701]; nonusers, 2.65% [787/29,701]; adjusted relative risk [aRR] 0.97; 95% CI 0.88-1.07). Among patients with confirmed COVID-19 in the GRCP-COVID cohort, 804 were statin users and 1573 were matched nonusers. Statin users were associated with a decreased likelihood of severe clinical outcomes (statin users, 3.98% [32/804]; nonusers, 5.40% [85/1573]; aRR 0.62; 95% CI 0.41-0.91) and length of hospital stay (statin users, 23.8 days; nonusers, 26.3 days; adjusted mean difference –2.87; 95% CI –5.68 to –0.93) than nonusers. The results of the NHIS-COVID cohort were similar to the primary results of the GRCP-COVID cohort.

Conclusions

Our findings indicate that prior statin use is related to a decreased risk of worsening clinical outcomes of COVID-19 and length of hospital stay but not to that of SARS-CoV-2 infection.

Authors: Reyes Velasco Jacobo , Grünwald Christoph Imre , Jones Jason Michael , Ahumada Carrillo Ivan Trinidad
Published: October 2021

The herpetofauna of Colima has received relatively little attention until recently. A few state lists and several unpublished dissertations are the only references available for the herpetofauna of the state. Recently a revised herpetofaunal state list was published by Lemos-Espinal et al. (2020). Unfortunately, that revision was published with numerous errors and omissions. Here we review all published accounts on the herpetofauna of Colima as well as two unpublished thesis related to the herpetofauna of the state, and records in online databases (GBIF, Vertnet). We examine museum specimens of previously published taxa and show that many of the species reported from the state are in fact misidentifications, and that other species already known from the state have been ignored in the most recent state list. Additionally we report on six species of amphibians and reptiles that are new records for the state. Based on our revision, we show that the herpetofauna of Colima consists of 148  species, of which 110 are reptiles and 38 are amphibians, with five introduced species.  We also comment on species of possible occurrence in the state. We recommend that other state lists which have been published for Mexico be revised in order to fix a variety of issues and erroneous information in those lists.

El objetivo principal del presente estudio piloto es analizar los niveles de conciliación trabajo-familia (clima familiar, conflicto trabajo-familia, interacción positiva e interacción negativa trabajo-familia) y variables psicosociales de salud (estrés, burnout, tensión laboral, satisfacción laboral y mentalidad hacia el estrés) con el fin de comparar dos grupos: profesores no universitarios y no profesores. Además, se analizarán las relaciones entre las variables de conciliación y las psicosociales. 95 sujetos (50 profesores y 45 trabajadores de otros colectivos) participaron en este estudio transversal. Los resultados muestran que los profesores puntúan significativamente más en clima familiar y en uso de habilidades en sus trabajos, y menos en burnout y mentalidad hacia el estrés. Además, en ambos grupos las variables de conciliación correlacionan con el uso de habilidades, burnout y estrés. Estos resultados se discuten enfatizando la puesta en práctica de medidas efectivas que ayuden a mejorar el bienestar laboral, familiar y personal.

Authors: Ray Richik
Published: October 2021

Abstract: In this paper, a MATLAB based Simulink model of a Series-Parallel Hybrid Electric Vehicle is presented. With the advent of Industry 4.0, the usage of Big Data, Machine Learning, Internet of Things, Artificial Intelligence, and similar groundbreaking domains of technology have usurped manual supervision in industrial as well as personal scenarios. This is aided by the drastic shift from orthodox and conventional Internal Combustion Engine based vehicles fuelled by fossil fuels in the order of petrol, diesel, etc., to fully functional electric vehicles developed by renowned companies, for example Tesla. Alongside 100% electric vehicles are hybrid vehicles that function on a system based on the integration of the conventional ICE and the modern Electric Propulsion System, which is referred to as the Hybrid Vehicle Drivetrain. Designs for modern HEVs and EVs are developed on computer software where simulations are run and all the essential parameters for the vehicle’s performance and sustainability are run and observed. This paper is articulated to discuss the parameters of a series-parallel HEV through an indepth MATLAB Simulink design, and further the observations are presented.

Literature in Culture & Culture in Literature: Explain 21ST century
Authors: Behera Dr. Sanghamitra
Published: October 2021

Abstract: As the cultural environment of the twenty first century comes into clear focus, Cambridge Studies in Twenty-First Century. Literature and culture presents a series of monographs that undertakes the most penetrating and religious analysis of contemporary culture and thoughts. The series is driven by perception that critical thinking today is in a state of transition. The global forces that produce cultural forms are entering into powerful new alignments, which demand new analytical vocabularies in the wake of later twentieth century theory. The series will demonstrate that theory is not simply availed revolutionary gesture that we need to move beyond, but rather brings us to the thresh hold of a new episteme, which will host work that explores the most important emerging critical contours of the 21st century, marrying inventive and imaginative criticism with theoretical and philosophical rigor. The aim of the series will be to produce an enduring account of the 21st century intellectual landscape that will not only stand as a record of the critical nature of our time, but that will also forge new critical language and vocabularies with which to navigate an unfolding age. Keyword: cultural environment, perception, revolutionary, episteme, transition, vocabularies

The adoption of Electric Vehicles (EV) is one of the solutions to reduce emission problems. In Indonesia, the government targets 2.1 million Electric Motorcycles (EM) ownership in 2025. One of the keys to encouraging the EV Indonesian market is vehicle cost analysis, like Total Cost of Ownership (TCO). This study developed a TCO model to compare EM with Conventional Motorcycles (CM) in Indonesia.  Data were collected from surveys and information from stakeholders. The proposed TCO model considered a battery replacement cost, which influenced the resale value of the vehicle. As a result, the TCO of EM had a more economical value than CM of 12% (IDR 3 million) on low mobility, 16% (IDR 4 million) on medium mobility, and 18% (IDR 5.5 million) on high mobility. In addition, several scenarios were also analyzed as a study to consider providing subsidies ownership motorcycles in Indonesia.

Industrial developments and environmental problems encourage decision-makers to determine optimal decisions. In addition, transportation is an aspect that has a significant contribution to environmental damage. Therefore, inventory and transportation decisions need to be integrated to minimize environmental problems. This study made an effort to develop a model of Sustainable EOQ with Multi Container Transportation Problems. The optimal procedure was proposed to determine the optimal number of containers in one vehicle. The results suggested that the proposed procedure could minimize the total annual inventory cost compared to the company's current solution.
Landscape intervention in the Hospital for Covid-19 pandemic in Madrid

Published: October 2021

From Design with Nature of Ian L. McHarg to The Origin of Eukaryotic Cells of Lynn Margulis, the role of the microorganisms in the cycle of life, health, and disease, and in climate change constitutes the life support system of the biosphere. The micro-parklands of the Emergency Hospital in Madrid create a natural system of prefabricated elements following the aim of rapid implementation, isolation, and protection taking as reference the simple integrated system of living microorganisms. These micro-enclosures provide circular areas where patients, visitors, or healthcare professionals can meet in secret places surrounded by trees and shrubs or long green islands where they can walk around. The landscape architecture project has a surface of 7,434 sqm and occupies a plot of 69,791 sqm located in the Hortaleza district of Madrid. Belonging to the previous City of Justice project on the north side of the Institute of Legal Medicine, the plot, which is trapezoidal with a drop of 4,5 meters, is destined for a public hospital constructed in four months during the Covid-19 pandemic. Due to dry climatic conditions, adapted species with low water demand have been selected reducing the risk of allergies or respiratory problems. The topography has been modified to conserve rainwater and direct it to green areas that act as sponges that reduce runoff, store water, remove sediment and pollutants and release it into other ecosystems. There is no separation between soft scape (planting) and hard scape (soil) in the intervention, both are soft and porous and have macro and micro living beings. Following the references of these books, creativity and destruction as real phenomena both have attributes such as fitness and unfitness in the evolutionary way or health and disease. The vital system of living organisms (creativity) and viruses (destruction) has guided the design and distribution of these external areas that intend to prevent infections in the open air, as part of the mutation and adaptation process.

Purpose: to improve the complex therapy of rotavirus infection in infants by including interferon and to evaluate its clinical and immunological effectiveness.

Materials and methods. Infants without infectious pathology and with rotavirus infection, who were on standard therapy and treatment, including standard therapy and interferon (20 in each group), were examined using general clinical methods. The diagnosis of rotavirus infection was carried out by molecular-genetic method and immunochromatography. Indicators of cellular immunity were determined by flow cytometry. Statistical processing of the results was carried out using the STATISTICA 8.0 program for related and independent samples using the nonparametric Mann-Whitney test and χ2.

Summary. In all infants with rotavirus infection, the disease occurred in a moderate form with symptoms of grade II exicosis. In the group of patients who received an additional interferon drug as part of complex therapy, the duration of intoxication symptoms was significantly less, and in the hemogram at discharge from the hospital, the relative content of neutrophils was higher and monocytes lower compared to infants who were only on standard treatment, which corresponded to the norm. In the acute period of rotavirus infection, the relative level of lymphocytes decreased, and NK cells and T-NK cells increased compared to healthy infants. The relative number of cells expressing TLR-3 at the beginning of the disease was lower than in the control group. The inclusion of interferon in the complex therapy contributes to normalization of the relative number of NK cells, while maintaining an increased content of T-NK cells in both relative and absolute terms compared to healthy infants, and a reduced content of cells expressing TLR-3.

Conclusion. Currently, rotavirus infection in infants is typical, the most pronounced and long-lasting clinical symptom of the disease is watery diarrhea. The use of interferon in complex therapy helps to reduce the duration of intoxication and normalize the hemogram. Changes in the immune status in the acute period of rotavirus infection indicate increased antigenic stimulation of the cell link and inhibition of the synthesis of pro-inflammatory cytokines, including interferons, under the influence of rotavirus, which is the justification for the use of interferon therapy.
