Authors: YILDIRIM Ferda , TEMEL MERT Zeynep
Published: November 2021

Aim: The aim of this study is to determine the relationship between family functionality perceptions of 12–15-year-old middle school students and sociodemographic variables. Methods: This descriptive study was conducted with 859 children between the ages of 12-15 in three primary schools. Data were collected using a survey form containing 14 questions about the students’ sociodemographic characteristics and the Family Assessment Scale (FAS) consisting of 60 items were used. Results: It was found that the highest average score of the students was in the 'roles' sub-dimension (28.81±2.71) and the lowest average score was in the 'problem-solving' sub-dimension (11.33±3.63) of the FAS, with the age of the students and the FAS sub-dimension. It was determined that the difference between all dimensions, gender, and “behavior control” was significant (p<0.05). The difference between maternal education level and all of the FAD sub-dimensions (p<0.05), and father education level and all sub-dimensions except problem-solving (Communication, Roles, Emotional Responsiveness, Showing Due Care, Behavior Control, General Functions) were significant (p<0.05). 0.05), among all sub-dimension items (PÇ, İLT, R, DTV, GİG, Gİ) except for 'behavior control' and family income level (p<0.05), children whose mothers and fathers are separated were 'showing the necessary attention' and it was determined that the difference between the sub-dimension mean scores of behavioral control were significant (p<0.05). Conclusion: One of the most important results of this study is that as the education level of mothers increases, students perceive their families more functional. Likewise, as the family income level increases, students perceive their families as more functional. This study is important in terms of determining the functional and non-functional areas of the family.
A Review of Database Security Concepts, Risks, and Problems
Authors: Teimoor Ramyar Abdulrahman
Published: November 2021

Currently, data production is as quick as possible; however, databases are collections of well-organized data that can be accessed, maintained, and updated quickly. Database systems are critical to your company because they convey data about sales transactions, product inventories, customer profiles, and marketing activities. To accomplish data manipulation and maintenance activities the Database Management System considered. Databases differ because their conclusions based on countless rules about what an invulnerable database constitutes. As a result, database protection seekers encounter difficulties in terms of a fantastic figure selection to maintain their database security. The main goal of this study is to identify the risk and how we can secure databases, encrypt sensitive data, modify system databases, and update database systems, as well as to evaluate some of the methods to handle these problems in security databases. However, because information plays such an important role in any organization, understanding the security risk and preventing it from occurring in any database system require a high level of knowledge. As a result, through this paper, all necessary information for any organization has been explained; in addition, also a new technological tool that plays an essential role in database security was discussed.
The Successful Synchronized Orchestration of an Investigator-Initiated Multicenter Trial Using a Clinical Trial Management System and Team Approach: Design and Utility Study
Authors: Mudaranthakam Dinesh Pal , Brown Alexandra , Kerling Elizabeth , Carlson Susan E , Valentine Christina J , Gajewski Byron
Published: November 2021

Background

As the cost of clinical trials continues to rise, novel approaches are required to ensure ethical allocation of resources. Multisite trials have been increasingly utilized in phase 1 trials for rare diseases and in phase 2 and 3 trials to meet accrual needs. The benefits of multisite trials include easier patient recruitment, expanded generalizability, and more robust statistical analyses. However, there are several problems more likely to arise in multisite trials, including accrual inequality, protocol nonadherence, data entry mistakes, and data integration difficulties.

Objective

The Biostatistics & Data Science department at the University of Kansas Medical Center developed a clinical trial management system (comprehensive research information system [CRIS]) specifically designed to streamline multisite clinical trial management.

Methods

A National Institute of Child Health and Human Development–funded phase 3 trial, the ADORE (assessment of docosahexaenoic acid [DHA] on reducing early preterm birth) trial fully utilized CRIS to provide automated accrual reports, centralize data capture, automate trial completion reports, and streamline data harmonization.

Results

Using the ADORE trial as an example, we describe the utility of CRIS in database design, regulatory compliance, training standardization, study management, and automated reporting. Our goal is to continue to build a CRIS through use in subsequent multisite trials. Reports generated to suit the needs of future studies will be available as templates.

Conclusions

The implementation of similar tools and systems could provide significant cost-saving and operational benefit to multisite trials.

Published: November 2021

Background

Health professions education has undergone major changes with the advent and adoption of digital technologies worldwide.

Objective

This study aims to map the existing evidence and identify gaps and research priorities to enable robust and relevant research in digital health professions education.

Methods

We searched for systematic reviews on the digital education of practicing and student health care professionals. We searched MEDLINE, Embase, Cochrane Library, Educational Research Information Center, CINAHL, and gray literature sources from January 2014 to July 2020. A total of 2 authors independently screened the studies, extracted the data, and synthesized the findings. We outlined the key characteristics of the included reviews, the quality of the evidence they synthesized, and recommendations for future research. We mapped the empirical findings and research recommendations against the newly developed conceptual framework.

Results

We identified 77 eligible systematic reviews. All of them included experimental studies and evaluated the effectiveness of digital education interventions in different health care disciplines or different digital education modalities. Most reviews included studies on various digital education modalities (22/77, 29%), virtual reality (19/77, 25%), and online education (10/77, 13%). Most reviews focused on health professions education in general (36/77, 47%), surgery (13/77, 17%), and nursing (11/77, 14%). The reviews mainly assessed participants’ skills (51/77, 66%) and knowledge (49/77, 64%) and included data from high-income countries (53/77, 69%). Our novel conceptual framework of digital health professions education comprises 6 key domains (context, infrastructure, education, learners, research, and quality improvement) and 16 subdomains. Finally, we identified 61 unique questions for future research in these reviews; these mapped to framework domains of education (29/61, 47% recommendations), context (17/61, 28% recommendations), infrastructure (9/61, 15% recommendations), learners (3/61, 5% recommendations), and research (3/61, 5% recommendations).

Conclusions

We identified a large number of research questions regarding digital education, which collectively reflect a diverse and comprehensive research agenda. Our conceptual framework will help educators and researchers plan, develop, and study digital education. More evidence from low- and middle-income countries is needed.
America’s HIV Epidemic Analysis Dashboard: Protocol for a Data Resource to Support Ending the HIV Epidemic in the United States
Authors: Sullivan Patrick Sean , Woodyatt Cory R , Kouzouian Oskian , Parrish Kristen J , Taussig Jennifer , Conlan Chris , Phillips Harold
Published: November 2021

Background

The Ending the HIV Epidemic (EHE) plan aims to end the HIV epidemic in the United States by 2030. Having timely and accessible data to assess progress toward EHE goals at the local level is a critical resource to achieve this goal.

Objective

The aim of this paper was to introduce America’s HIV Epidemic Analysis Dashboard (AHEAD), a data visualization tool that displays relevant data on the 6 HIV indicators provided by the Centers for Disease Control and Prevention. AHEAD can be used to monitor progress toward ending the HIV epidemic in local communities across the United States. Its objective is to make data available to stakeholders, which can be used to measure national and local progress toward 2025 and 2030 EHE goals and to help jurisdictions make local decisions that are grounded in high-quality data.

Methods

AHEAD displays data from public health data systems (eg, surveillance systems and census data), organized around the 6 EHE indicators (HIV incidence, knowledge of HIV status, HIV diagnoses, linkage to HIV medical care, viral HIV suppression, and preexposure prophylaxis coverage). Data are displayed for each of the EHE priority areas (48 counties in Washington, District of Columbia, and San Juan, Puerto Rico) which accounted for more than 50% of all US HIV diagnoses in 2016 and 2017 and 7 primarily southern states with high rates of HIV in rural communities. AHEAD also displays data for the 43 remaining states for which data are available. Data features prioritize interactive data visualization tools that allow users to compare indicator data stratified by sex at birth, race or ethnicity, age, and transmission category within a jurisdiction (when available) or compare data on EHE indicators between jurisdictions.

Results

AHEAD was launched on August 14, 2020. In the 11 months since its launch, the Dashboard has been visited 26,591 times by 17,600 unique users. About one-quarter of all users returned to the Dashboard at least once. On average, users engaged with 2.4 pages during their visit to the Dashboard, indicating that the average user goes beyond the informational landing page to engage with 1 or more pages of data and content. The most frequently visited content pages are the jurisdiction webpages.

Conclusions

The Ending the HIV Epidemic plan is described as a “whole of society” effort. Societal public health initiatives require objective indicators and require that all societal stakeholders have transparent access to indicator data at the level of the health jurisdictions responsible for meeting the goals of the plan. Data transparency empowers local stakeholders to track movement toward EHE goals, identify areas with needs for improvement, and make data-informed adjustments to deploy the expertise and resources required to locally tailor and implement strategies to end the HIV epidemic in their jurisdiction.
Predicting the Number of Suicides in Japan Using Internet Search Queries: Vector Autoregression Time Series Model
Authors: Taira Kazuya , Hosokawa Rikuya , Itatani Tomoya , Fujita Sumio
Published: November 2021

Background

The number of suicides in Japan increased during the COVID-19 pandemic. Predicting the number of suicides is important to take timely preventive measures.

Objective

This study aims to clarify whether the number of suicides can be predicted by suicide-related search queries used before searching for the keyword “suicide.”

Methods

This study uses the infoveillance approach for suicide in Japan by search trends in search engines. The monthly number of suicides by gender, collected and published by the National Police Agency, was used as an outcome variable. The number of searches by gender with queries associated with “suicide” on “Yahoo! JAPAN Search” from January 2016 to December 2020 was used as a predictive variable. The following five phrases highly relevant to suicide were used as search terms before searching for the keyword “suicide” and extracted and used for analyses: “abuse”; “work, don’t want to go”; “company, want to quit”; “divorce”; and “no money.” The augmented Dickey-Fuller and Johansen tests were performed for the original series and to verify the existence of unit roots and cointegration for each variable, respectively. The vector autoregression model was applied to predict the number of suicides. The Breusch-Godfrey Lagrangian multiplier (BG-LM) test, autoregressive conditional heteroskedasticity Lagrangian multiplier (ARCH-LM) test, and Jarque-Bera (JB) test were used to confirm model convergence. In addition, a Granger causality test was performed for each predictive variable.

Results

In the original series, unit roots were found in the trend model, whereas in the first-order difference series, both men (minimum tau 3: −9.24; max tau 3: −5.38) and women (minimum tau 3: −9.24; max tau 3: −5.38) had no unit roots for all variables. In the Johansen test, a cointegration relationship was observed among several variables. The queries used in the converged models were “divorce” for men (BG-LM test: P=.55; ARCH-LM test: P=.63; JB test: P=.66) and “no money” for women (BG-LM test: P=.17; ARCH-LM test: P=.15; JB test: P=.10). In the Granger causality test for each variable, “divorce” was significant for both men (F104=3.29; P=.04) and women (F104=3.23; P=.04).

Conclusions

The number of suicides can be predicted by search queries related to the keyword “suicide.” Previous studies have reported that financial poverty and divorce are associated with suicide. The results of this study, in which search queries on “no money” and “divorce” predicted suicide, support the findings of previous studies. Further research on the economic poverty of women and those with complex problems is necessary.
Pareto-based Dynamic Difficulty Adjustment of a Competitive Exergame for Arm Rehabilitation (Preprint)
Authors: Rammohan Mallipeddi , Ajani Oladayo Solomon
Published: November 2021

BACKGROUND

Lack of motivation is a major hindrance to frequent and intense exercise which is critical to rehabilitating people with arm disabilities due to old age, neurological disorders or stroke. Recently, the use of interpersonal exergames has been associated with increased motivation and exercise intensity in arm rehabilitation and is becoming a common trend. However, the Dynamic Difficulty Adjustment (DDA) of such games is still an open issue because unlike the traditional DDA frameworks where game intensity is simply adapted to suit the players' performance, the aim of DDA for exergames is to optimize the conflicting objectives namely of intensity and performance.
Objective: To design a dedicated DDA for rehabilitation exergames that optimize the conflicting objectives of intensity and performance by generating a set of feasible trade-off solutions. Based on the rehabilitative needs, the tradeoff worth information of each solution is to be used to select a unique solution.

OBJECTIVE

To design a dedicated DDA for rehabilitation exergames that optimizes the conflicting objectives of intensity and performance by generating a set of feasible trade-off solutions. Based on the rehabilitative needs, the tradeoff worth information of each solution is to be used to select a unique solution.

METHODS

We designed a Pareto-based DDA for a competitive exergame that optimizes the two conflicting objectives. Using a set of feasible solutions generated during the first episode of the game, the proposed Pareto-based DDA is used to modify the parameters of the game. Optimizing conflicting objectives generally results in a set of trade-off solutions called Pareto optimal set instead of a single solution. Therefore, the DDA is capable of selecting a single solution from the optimal Pareto based on the trade-off worth information of each solution in the optimal Pareto set.

RESULTS

Results: Experimental results with 12 unimpaired participants show the capability of the proposed Pareto-based DDA to online adjust the game parameters effectively based on a trade-off between the intensity and motivation.

CONCLUSIONS

Since rehabilitation outcomes rely on both intensity and motivation, unlike traditional DDA approaches, the capability of Pareto-based DDA to provide trade-off solutions between conflicting objectives of intensity and motivation is very promising to rehabilitation outcomes. However, multi-session investigation over a period of time needs to be carried out to examine if they influence rehabilitation outcomes positively.

CLINICALTRIAL

This work is not a clinical trial. Although humans participated in this study, they participate in the evaluation of a single-session of a rehabilitation exergame rather than a comprehensive rehabilitation intervention with no health outcomes investigated.

ORBITAL UNCERTAINTY ESTIMATION SUPPORT FOR AUTONOMOUS SPACE DEBRIS OBSERVATION
Authors: Jiang H. , Liu J. , Cheng H. W.
Published: November 2021

The continually increased space debris have posed great impact risks to existing space systems and human space ﬂight. Accurate knowledge of propagation errors of space debris orbit is essential for many types of uses, such as space surveillance network tasking, conjunction analysis etc. Unfortunately, propagation error is not available for a two-line element (TLE). In this paper, a new TLE uncertainty estimation method based on neural network model is proposed. Object properties, space environment and predicted time-span are considered as the input of the network, the propagation errors in the direction of downrange, normal and conormal are as the output of the network. In order to assure the chosen orbit for training is not stable, only debris and rocket bodies are used. The network's effciency is demonstrated with some objects with continuous TLE data. Overall, the method proves accurate, computationally fast, and robust, and is applicable to any object in the satellite catalogue, especially for those newly launched objects.

GWAC will have been built an integrated FOV of 5,000 degree2 and have already built 1,800 square degree2. The limit magnitude of a 10-second exposure image in the moonless night is 16R. In each observation night, GWAC produces about 0.7TB of raw data, and the data processing pipeline generates millions of single frame alerts. We describe the GWAC Data Processing and Management System (GPMS), including hardware architecture, database, detection-filtering-validation of transient candidates, data archiving, and user interfaces for the check of transient and the monitor of the system. GPMS combines general technology and software in astronomy and computer field, and use some advanced technologies such as deep learning. Practical results show that GPMS can fully meet the scientific data processing requirement of GWAC. It can online accomplish the detection, filtering and validation of millions of transient candidates, and feedback the final results to the astronomer in real-time. During the observation from October of 2018 to December of 2019, we have already found 102 transients.

Behavior of Native Food Isolates of Listeria monocytogenes and Listeria innocua under the Influence of Selected Cultural Attributes and Heat and Cold Treatments
Authors: Hampapura Jayanth Sunderraj , Chakravarathy Varadaraj Mandyam
Published: November 2021

The present investigation assesses the influence of cultural attributes and heat and cold treatments on the behaviour of native toxigenic L. monocytogenes CFR 1302 and non-toxigenic L. innocua CFR 1304 in selected medium. The growth responses of L. monocytogenes and L. innocua under the influencing factors of storage temperature (10-40°C), pH level (5.5-7.5), and storage period (6-48 h) in brain heart infusion and nutrient broths revealed closeness between observed and predicted populations. Response surface plots were generated for the growth behavior of the two test cultures as a function of pH level. The toxigenic L. monocytogenes CFR 1302 could reach a higher viable population. The effect of heat treatment on Listeria spp. in selected five heating menstra showed the lowest D-value of 3.7 min at 60°C for L. innocua CFR 1304 in Milli-Q water to the highest of 8.4 min at 56°C for L. monocytogenes CFR 1302 in skim milk. The average z-value across the heating menstra for L. monocytogenes was 27.3°C as against that of 22°C for L. innocua. In the case of cold treatment, storage of 4 and 8°C resulted in appreciable increase in counts of L. monocytogenes CFR 1302 from the initial inoculum introduced in selected media. At -20°C, there was a slight decrease in the viable population. The research data helps to predict the viable populations of L. monocytogenes as a part of risk assessment in the food chain. This is of significance in providing safe and healthy food to human population.
Applying Data Science to Assess Postpartum Depression in Women from Rural Bihar in India
Authors: Sinha CRia
Published: November 2021

Abstract: Postpartum Depression (PPD) affects women during pregnancy or within a year of giving birth. This paper uses data science principles to study the prevalence of PPD in women from the state of Bihar in India. Data was obtained by trained surveyors for a random sample of 531 women, aged 15 to 41 years old, who had been pregnant or recently given birth. Our results show a significant occurrence of PPD in the population with 24% ± 4% of women showing symptoms based on a 95% confidence interval. We analyze the impact of age, number of children and sex of the last child on PPD. PPD was found to be 70% more prevalent in women between the ages of 30 and 39, correlated with them having more children.

ANALYTICAL QUALITY-BY-DESIGN (AQBD) APPROACH FOR THE DEVELOPMENT AND VALIDATION OF RP-HPLC METHOD FOR THE ESTIMATION OF LAMOTRIGINE IN BULK AND TABLET FORMULATION
Authors: Puranik Manisha P.
Published: November 2021

The current analytical exploration illustrated developing a reversed-phase high-performance liquid chromatography (RP-HPLC) technique and consequent substantiation for analyzing lamotrigine (LAM) active pharmaceutical ingredient (API) using a Quality-by-design (QbD) approach (Central Composite Design), in bulk product as well as in the tablet formulations. In this experiment, based on systematic scouting, four key components (viz., mobile phase, column, flow-rate, and wavelength) were studied by the RP-HPLC method. 13 experimental runs were done with acetonitrile (ACN) (40-60% v/v) having flow-rate in the range 0.8 mL/min to 1.2 mL/min. The proposed analytical method was thoroughly corroborated in terms of ruggedness linearity, robustness, accuracy, and precision in accordance with ICH guideline Q2A and ICH guideline Q2B. Under the optimum chromatographic environment; Intersil C8 column of 250 mm length, 4.6 mm (i.d.); 20 μL injection volume; and mobile phase ACN: Methanol (60:40 v/v), a retention time of 2.542 min was noticed at 220 nm detection wavelength. The method was found to be extremely reproducible, accurate, linear, precise, robust, and economically adequate to execute the estimation. The intended analytical technique was thoroughly assessed through statistical tools and could be an imperative concern for the habitual scrutiny of LAM in bulk products and its formulation.
The Revolution is Over, Forget It: To the 30th Anniversary of the Russian Federation
Authors: Nisnevich Yuliy A.
Published: November 2021

After the collapse of the Soviet Union, the power in post-Soviet Russia was seized by the leaders of the democratic movement - first wave democrats, and the more progressive Soviet nomenclature. As a result of the miscalculations made by the leaders of the democratic movement, the representatives of the Soviet nomenclature soon started displacing the first wave democrats and the reformers of the Gaidar call from the Russian governmental bodies in order to gain full control over the governance in the country. This appeared to be a manifestation of the more general and fundamental process, where the Russian nomenclature separated from the democratic movement, emerging as a new ruling stratum - the immediate heir to the Soviet nomenclature. The turning point, which accelerated the separation and the retreat of the Russian nomenclature from liberal and democratic principles of the countrys modernization, was the beginning of the Chechen tragedy in 1994. Not only did the Chechen events separate the Russian nomenclature and the democratic movement but also split the democratic movement itself. The goal of the article is to examine the transformation of the relationship between the democratic movement and the soviet and, later on, Russian nomenclature during the revolutionary changes of the early 1990s.
Political and Civic Identity of Libertarians in Contemporary Russia: Problems and Perspectives
Authors: Dumler Denis A.
Published: November 2021

Libertarianism is a new ideological trend, popular among young people. We try to find out whether libertarianism rises as independent political movement or it is the reaction on the fall of popularity of traditional political parties. For that purpose, the author made the comparative analysis of the program documents of the Libertarian Party of Russia with the classical works of the American libertarians and analyzed the published interview both of the party leaders/activists and of the experts. The author used the interview which he took from some activists in order to clarify the political identification of the Russian libertarians. The political identity of libertarians is characterized by the broadest possible interpretation of personal and economic freedom. Libertarians believe that such freedom is compatible with law and legality and is opposite to anarchy. At the same time, they avoid definitions and norms that could constrain freedom by both the state and the adherents of certain, including liberal, values and slogans. This broad approach makes it difficult to politically identify libertarians, but contributes to their attractiveness among young people.
Development of environmental measures to reduce the dusty emissions of stone coal in loading and unloading works
Authors: Lukanin Alexander V. , Klevanova Elena S.
Published: November 2021

Now Russia is one of the worlds leading coal producers. Particles inevitably pass into an aerosol state, forming dust, which is subsequently emitted into the atmosphere during the extraction, crushing, sorting and transportation of coal. This dust negatively affects the health of workers in the mining industry, as well as the population of the residential area. In this regard, the question arises about the effective air cleaning in the working area from coal dust and reducing its concentration. The work purpose is to develop a comprehensive cleaning of gas-air emissions from coal dust in the working area where it is transported. The main task is to create an additional degree of air purification from coal dust. For this purpose, a vortex absorber was used, which is a cylindrical apparatus in which a contact element with perforated holes is located. The geometric dimensions of the absorber and its main parameters have been determined. The absorber developed by the authors has shown very good results as a device for the final purification of gas-air emissions. The efficiency of trapping small solid particles in the presented scheme reaches 99%. At the same time, as a result of the introduction of this installation, effective air purification from dust particles with a diameter of about 0.2 microns is carried out and the coal briquettes production is increased by 144 tons per year.
Methodology for the economic estimation of the environmental damages caused by land, soil and air pollution in Kenya: a review of previously used methods
Authors: Mamboleo Martin
Published: November 2021

Environmental compensation is a form of payment for pollution of nature and the environment and the destruction of land, plants or animals. One of the challenges in ensuring waste management in Kenya is how to measure the negative effect of industrial activities and waste on the environment, economy, and human health. Although the amount of compensation should be established on the basis of the environmental-economic assessment of the appropriate environment, it should also be sufficient to implement measures aimed at restoring, reproducing and improving this environment. Kenya has not yet developed a clear legal framework for compensation for environmental damage even through it has a clear and elaborate Environmental Management and Coordination Act for the protection of the environment. Previous studies on the cost of environmental damage in Kenya have successfully used two methodologies: emergency costs and soil, air, and water pollution. This works examines the essence of these methods, as well as the possibility of their application in assessing the cost of damage to the environment as a result of human economic activity.

Published: November 2021

The results of the floristic and hydrobiological studies performed in May - August 2020 on the territory of the ecological park Samara Venice (Samara Region, Russia) are presented. These data form the basis for the ecological assessment of the territory. The diversity of vascular plants is presented by 4 divisions, 65 families, 205 genera, and 309 species. Among them, 66 species (21.4%) belong to the alien plant species, including nine invasive. Habitats of the plants included in the regional Red List are found. The zooplankton diversity comprises 60 species and morphs. The zooplankton community has undergone significant transformation, manifesting by an increase in the total biomass and in the biomass of crustaceans and rotifers, and by a decrease in absolute and relative species richness. It is revealed that a number of the studied water bodies belong to the transitional type, and may be characterized as of middle position between the meso- to eutrophic type (moderately polluted and polluted waters).

The provisions of the halal standards in force in the Republic of Turkey and the United Arab Emirates are examined. The differences in the requirements for halal products established in the indicated countries are analyzed. Halal products are gaining popularity in the consumer market. According to the results of the report on the Islamic economy, the growth in popularity by 2020 will be 6.5%. At the same time, there is a constant trend o f growth in market volumes. There is a report from the Center for Development of Islamic Economy in Dubai that Muslims spent $ 2.2 trillion in 2018, while by 2020 this amount was $ 2.4 trillion. The global development of the halal food market and its frequent discrepancies in the concept, the lack of uniform rules for handling products leads to disunity of the rules for handling products. It should be remembered that the Republic of Turkey and the United Arab Emirates, being members of the Islamic Cooperation, are also the main suppliers of halal goods. Moreover, both states should have the same requirements for halal, which nevertheless differ. In the Republic of Turkey, halal food requirements and slaughter rules are set out in one standard TS OIC/SMIIC 1 General Guidelines for Halal Foods. In the UAE, the same requirements are set out in two standards: UAE.S GSO 993 Requirements for slaughtering animals in accordance with Islamic rules and UAE.S GSO 2055-1 Halal Food. Part 1. General Requirements. A study of the requirements for halal products and processes, set out in the standards of the two countries, showed that on fundamental issues they coincide. But there are also certain differences in the requirements that can become a problem when supplying the same products to Turkey and the UAE.

The impact of Taldan crushed stone plant and wastes formed in process of its activity on the environment is considered. About 2.9 million tons of siftings of rock grinding were accumulated in dump massifs with a total area of 600 hectares. Therefore, elimination of accumulated harm to the environment that has arisen over many years of operation of Taldan crushed stone plant is the actual task. One of the technological solutions of liquidation of objects of accumulated harm to the environment based on physicochemical impact on wastes is stabilization or artificial stone formation. Drawing of siftings of rock in soil concrete compositions (artificial stone materials) allows to solve complex of acute environmental problems due to their largetonnage direct use. The use of siftings of rock in road building will contribute to the rational and cost-effective use of natural mineral raw materials, since this process will not entail an increase in the costs of its extraction and processing. A set of modern methods (atomic-emission spectrometry with inductively coupled plasma, scanning electron microscopy, X-ray phase analysis, infrared spectroscopy) were used to study the chemical, phase composition and properties of siftings of rock to substantiate the possibility of its utilization in the composition of soil concrete. It is shown that the introduction of an 8 wt. % of mineral binder and polymer stabilizing additive Element (1, 5, 10 wt. %) allows to get soil concrete with a mark of strength М100.

Authors: Jabrayilov Emil Akif oghlu
Published: November 2021

The high growth rate of consumption of natural resources by people in the last century have seriously and negatively affected ecosystems and led to the loss of biodiversity. At present, it is important to take the necessary measures to ensure sustainable development and biodiversity conservation. Ecological networks play an important role in maintaining and controlling the stability and balance of communication between ecosystem complexes. For this purpose, the possibility of creating an ecological network that includes core areas, buffer zones, ecological corridors and restoration areas in the section of Shamakhi district of the Shahdagh National Park was explored. The designated buffer zone of the national park includes 14 villages and 1 settlement type administrative unit. Mountainous landscapes predominate in the area, and the absolute height ranges from 500-200 m. Riverbeds, intermountain depression, mountain passes, trails and forests which should be planted in the areas we offer, were considered as main factors during the construction of ecological corridors in the national park and the buffer zones. The materials obtained from the literature and our field studies, also, vector and raster data were used during the site identification. The data was processed in software such as ArcGIS 10, ERDAS Imagine, Global Mapper, Google Earth, etc. Existing ecosystems were identified, and areas were calculated in separate elements of the ecological network in the study area.
