Published: June 2021

The article presents on observations made in the period from 2019 to 2021 and contains research materials on the distribution and seasonal changes of the avifauna of the city of Turkestan. The main research method is route and 5-minute boundary control. As a result of the study, it was found that 70 species of birds belonging to 11 orders live in various landscape areas of the city of Turkestan. Among them 5 species of Columbiformеs, 45 species of Passeriformes, 6 species of Falconiformes, 2 types of Ciconiiformess, 2 species of Caprimulgiformes, 2 species of Strigiformes, 2 species of Piciformes, 1 species of Cuculiformes, 2 types of Apodiformes and 2 species of Galliformes. The variety of birds varies by season. 14 species were recorded in winter, 51-in spring, 63-in summer and 39-in autumn. The location of birds on the territory also varies depending on the season. Insectivorous (51.0 %) and granivores (43.0 %) birds occupy the leading positions in the main component of the food composition. The most extensive spectrum is found on the territory of park areas: up to 20 species have been recorded there. The avifauna of open spaces and multi-storey structures is poor, there are 9 species and 5 of them nest. In the course of determining the number of birds in the city, several dominant species were identified. These are: A Pica pica from the family of Corvidae, а сorvus corone, a Passer domesticus from the family of Passeridae.

Published: June 2021

The evolution of modern humans began two and a half million years ago as Homo erectus. Several hundred thousand years ago, Neanderthals, Denisovans, and modern men Homo sapiens have been separated from the Homo erectus branch. Nevertheless, Homo sapiens is the only one that has survived to our days. The complex history of Homo is revealed by genetic research and comparison of the modern human genome with genes of Neanderthals and Denisovans. Svante Pääbo, a professor at the Max Planck Institute for Evolutionary Anthropology, made a significant contribution to these studies and decoded the genome of Neanderthals and Denisovans. Comparison of the genome of modern humans with the genes of Neanderthals and Denisovans made it possible to reveal the size of the population, the paths and times of migrations, interactions of various groups of ancient humans and their biological crossing. It was found that in Eurasia, modern man carries traces of Neanderthal genes, whereas in Asia and Oceania – Denisovan genes. According to anthropological research, the survival of Homo sapiens was driven by the cognitive revolution, which took place about seventy thousand years ago and included the development of language, communication and association in large groups.

Background: Due to the high content of nitrogen in the municipal wastewaters, this study evaluated the efficiency of Scenedesmus as an important microalgae in the removal of nitrate from wastewaters and its application as an appropriate culture medium. As algae have high resistance to temperature and pH changes, they can absorb low concentrations of nutrients and need simple low-cost technology. Through photosynthesis, microalgae effectively stabilize carbon dioxide at a low cost, and the oxygen produced by the photosynthesis process can reduce the biochemical oxygen demand (BOD) of wastewaters. Methods: In this research, the chemical oxygen demand (COD), BOD, pH, total nitrogen (TN), and microalgae density were measured in the samples within 14 days after sampling from the inlet and outlet of municipal wastewaters treatment plant. Results: The results showed that nitrogen removal rate from the wastewaters at the laboratory conditions was 93% in the inlet and 85% in the outlet, which are higher in efficiency than those provided by other treatment processes. Conclusion: The microalgae can be used for the removal of nitrate and the production of algae biomass in municipal wastewaters processes before entering the natural environment.

Background: The present study investigated the protective effect of C. myxa extract on the liver biochemical and histologic changes induced by cadmium chloride (CdCl2) in adult male rats. Methods: We used 48 adults male Wistar rats, divided into 6 groups of 8. Control group received water and normal food. Sham group 1 received 2 mg/kg of CdCl2 for 35 days intraperitoneally. In Addition, Sham Group 2 received 125 mg/kg extract of C. myxa fruit for 35 days by gavage method. The experimental groups 1, 2 and 3 received 125, 250 and 500 mg/kg of C. myxa extract for 21 days through gavage, followed by 2 mg/kg of CdCl2 given intraperitoneally for 14 days. After the experimentation period, blood samples were taken and the serum total protein and albumin concentrations measured. Also, liver tissue sections were prepared, stained and examined by light microscopy to evaluate the histologic changes. Results: The mean body weight, serum total protein, albumin in sham group 1 showed a significant decrease in comparison with those in the controls and Sham Group 2. The mean body weight and serum total protein in Experimental Groups 2 and 3 showed a significant increase compared to those in Sham Group 1. The mean serum albumin in Experimental Group 3 showed a significant increase compared to that in Sham Group 1 (P <0.05). Conclusion: The extract of C. myxa fruit demonstrated protective effects on changes in body weight, serum biochemical factors and liver histology induced by the adverse effect of CdCl2 in adult male rats.

Background: Synthetic coagulants commonly used for water treatment are associated with undesirable properties, such as inefficacy and toxicity in addition to being expensive. Natural coagulants are considered safe and economical alternatives for developing countries where the plants are abundantly available. Methods: The phytochemical composition and safety of water samples treated with Mangifera indica (M. indica) were evaluated in 13 groups of albino rats (N=36) for four weeks and compared with water samples treated with alum and calcium hypochlorite, using biochemical and hematological parameters. Results: Mangifera indica bark contained alkaloids, flavonoids, saponins, phenols, tannins, terpenes, steroids and cardiac glycoside. Both the raw water samples (rivers, ponds & streams) and treated waters (alum, calcium hypochlorite and plant material) did not caused any significant (p>0.05) changes to the activities or levels of transaminases (AST and ALT), alkaline phosphatase, total serum proteins, urea, creatinine, sodium, potassium, platelet and mean corpuscular hemoglobin concentration compared with those in normal control rats. Water samples treated with M. indica caused significant increases (p<0.05) in packed cell volume, hemoglobin, and red blood cells of the animals while the untreated water samples significantly increased the white blood cell. However, alum treated water significantly increased (p<0.05) the concentrations of serum urea, sodium and potassium while calcium hypochlorite treated water significantly (p<0.05) increased the creatinine and potassium concentrations. Conclusion: The use of M. indica bark in water purification confers hematopoietic properties to the water and reduces adverse effects on the biochemical parameters, thus could be considered as an effective and safe agent for water purification.

Background: This study investigated the concentration of some heavy metals in plastic housing of televisions produced over three decade (1980-2000) with the aim of providing information and comparing the trend in the concentration of these metals. Methods: The heavy metal concentrations were determined by atomic absorption spectroscopy after acid digestion using a 1:1 mixture of sulphuric and nitric acid. Results: The mean concentration of the heavy metals (mg/kg) in the television sets for 1980s, 1990s and 2000s, respectively, were as follows: 12.75 (Nd); 1.32 (Pb); 1.84, 1.47 & 2.79 (Ni); 1.53, 16.19 & 40.42 (Ag); 82.24, 159.69 & 113.29 (Zn); 7.12, 4.23 & 5.26 (Cr); 3.26, 2.76 & 2.39 (Cu); 4.84, 24.05 & 26.67 (V); 9.30, 8.40 & 12.63 (Co); 2.59, 4.05 & 4.28 (Cd). Conclusion: Although the mean concentrations for Zn, Cu and Ag in the television samples were relatively high, compared to the total threshold limit concentration (TTLC), they were below the threshold limit. These results suggest that there may not be any immediate environmental hazard posed from the TV plastic housings. The correlations analysis showed that most of the metals declined in TV housings over the subsequent decades.

Authors:   Department of Neurosurgery, Shiraz University of Medical Sciences, Shiraz, Iran., Rahmanian Abdolkarim
Published: June 2021

Cerebrovascular diseases comprise a major subspecialty in neurological surgery. Current education curriculums lack the necessary training modalities for teaching the microvascular techniques, to neurosurgery residents. We have included a 1-month micro-lab and animal lab rotation for senior residents, which can be added to their current educational program. Necessary equipment for this rotation includes an operating microscope Zeiss S8, microsurgical instruments, and animal anesthesia equipment are used to perform revascularization techniques on the aorta of a rat model (average-sized Sprague-Dawley weighing 200-250 gram). This rotation was included in previous curriculums as micro-lab. Evaluation of microvascular surgical skills following the addition of animal models to this skill lab is suggested to be considered as a part of OSCE in board certification in future studies. The addition of animal models to micro-lab rotations, provides a better understanding of tissue consistency while dealing with a microvascular surgery procedure, for neurological surgery residents.

Published: June 2021

This study aims at introducing and discussing the concept of ‘academic culture,’ the Chinese concept of ‘talent cultivation’, and the influence of ‘academic culture’ in the process of ‘talent cultivation’in the Chinese context. It uses the analysis of some observation notes and relevant literature that examines the issue of ‘academic culture’. The Chinese ‘talent cultivation’is fascinating and seems useful due to the significant development of the higher education system with the increasing internationalization and the innovation of scholars. However, some challenges such as academic scandals and academic corruption, the falsification and plagiarism of academic achievements, the phenomenon of money-worshipping, the vulgar pragmatism, the utilitarianism, the academic creation of falsehood, the culture of guanxi, the lack of talent competition, and the lack of competition with consciousness remain actual. It appears that the cultivation of creative talent and innovative research involves the enhancement of the whole academic organization and environment.
Situated Learning – Foreign Sites as Learning Contexts
Authors: Chang Bo
Published: June 2021

As part of the globalization effort, study abroad has been researched in the fields of education, business, language, etc. However, what is not well-discussed is how foreign sites in study abroad programs can function as learning contexts to promote in-depth learning in various subject areas, which was the purpose of this study. Twelve participants from one public research university involved in some study abroad programs were interviewed. Documents such as syllabi and travel plans relevant to participants’ trip were also collected. The data were analyzed inductively. The findings show that foreign sites serve as learning context to support students’ learning by (a) providing cues to understand new knowledge from different perspectives; (b) providing a context to understand the meaning behind words; (c) providing minute details tying facts towards abstract knowledge; and (d) creating a space for stimulating emotional attachments.

Il suicidio è l’atto umano di porre fine alla propria vita. Gli atteggiamenti suicidi con l’intenzione di morire, ma senza portare alla morte, sono chiamati tentativi di suicidio, cioè sono atti intenzionali di autolesionismo senza che il risultato sia la morte. Questo studio ha analizzato, epidemiologicamente, le cure fornite dal Mobile Emergency Service – SAMU / AP relative ai tentativi di suicidio nel 2018 a Macapá / AP. È stata condotta una ricerca trasversale, descrittiva e quantitativa. I dati sono stati raccolti da 61 record di cure iniziali riferiti a eventi nel 2018, dal sistema di archiviazione di file SAMU / AP. Questo studio ha permesso di ampliare la conoscenza delle caratteristiche dei casi di tentativi di suicidio e suicidi consumati avvenuti a Macapá / AP, consentendo così al supporto di professionisti di lavorare su interventi con la popolazione alla ricerca della riduzione delle statistiche esistenti. È interessante notare che il problema della mancata o notifica di casi di tentato suicidio eseguiti in modo insufficiente è un aspetto importante per l’indebolimento delle informazioni epidemiologiche, delle azioni di assistenza in rete e per la realizzazione della territorializzazione e intersettoriale nella salute mentale. Azioni educative e politiche pubbliche che rafforzano al medico e alle squadre di pronto soccorso in generale l’importanza della corretta e completa registrazione delle informazioni.

Effective economic activity of any enterprise, regardless of size, is an important factor in the economic and social development of the country's economy, improving the welfare and quality of life of the population, increasing the GDP of the state and the like. To succeed in business today, entrepreneurs need to be flexible and have good planning and organization skills. The growing uncertainty and variability of the external environment require entrepreneurs and managers to be highly competent in setting up business structures. Accordingly, the question arises of determining the ultimate goal of the creation and operation of the business (enterprise), as well as the formation of the terminological field (set of terms), which are used for this purpose. The purpose of the article is to deepen the study of the problem of assessing the success of entrepreneurship and ways to increase the success of small and medium-sized businesses. The relevance of the article lies in the need to disclose the content of the concept of "enterprise success", which is an integral qualitative characteristic of the state of the enterprise, reflects the presence of competitive advantages and the potential for further development. The article describes the characteristics of the concept of "enterprise success" through the systematization of the definition of the concept by other authors and highlighting the key aspects of focusing attention. The methodological approaches to assessing the success of the business of various scientists are highlighted and their developments are analyzed. Theoretical research methods have been applied to form new hypotheses regarding the definition and analysis of academic performance. The result of the study was the selection and meaningful disclosure of the most important criteria for the success of an enterprise, including measures of success for both owners and consumers and partners / investors. A “portrait” of a successful enterprise has been formed.

Published: June 2021

Recently, marketing has become an integral part of the strategies of many organizations. It becomes more and more understandable and used in Ukraine, and, if earlier this phenomenon of economic life was a kind of exoticism, namely the word "marketing" seemed strange, now marketing is the most important component of the success of any enterprises, firms, companies: large and Small, commercial and non-profit, national and international. As in any other system, it is impossible to determine the most important component. Potentially, each of them, in case of failure, will be able to destroy the entire mechanism. But special attention should be drawn to the compliance of the program's goal and strategy. For the construction of the program and the definition with the strategy it is necessary to conduct an economic analysis of the environment in which the enterprise functions and determine marketing potential. Marketing activities are even and currently aimed at identifying specific objectives and ways of their implementation. In the modern world, the manufacturer must produce such products that will find sales and bring profits to the enterprise. To do this, it is necessary to study the social and individual needs of the client, a market request as a condition and prerequisite for production. The concept lies in the fact that production begins with consumption rather than exchange. Marketing potential is a component of production capacity and is considered as potential: - production; - Marketing; - informational; - technical and technological; - organizational; - social; - Financial. Each segment affects others. Under similar potential, the possibility of all factors to form competitiveness of the enterprise is considered. Marketing potential is an integral part of a marketing strategy that focuses on improving the competitiveness and growth of enterprise profits through the unification of all its resources to identify and attract consumers and maintaining the most profitable ones. Consider the marketing potential of the enterprise "Otis" we will be on the side of assessing the results of obtaining new clients through the analysis of conversion and recovery indicators, as well as customer retention and cash flow analysis.

The methodology of regional management has been considered in this article. It has been noted that it consists of three components: economic, social and environmental, which are in interaction with each other. It has been concluded that the methodology of regional management should be aimed at involving different participants in the development process and planning in order to create a common perspective. It has been determined that the implementation and enforcement of regional economic policy is the most important component through which it is possible to achieve effective implementation of management decisions. It has been concluded that the methodology of regional management includes several components, namely: development of a strategic platform, component plans and a plan for monitoring and evaluation of implementation measures. Of these three components, such a component as the analysis of regional economic policy has been identified. Conduction of a qualitative economic analysis of regional economic policy is a very important element of the methodology of regional management, because thanks to it this is possible to determine the priority of the application of all regional policies. As mentioned earlier, economic analysis of regional policy is an integral part of the methodology of regional management. Based on the work of Olexander Kilievich in which two aspects of any economic analysis of regional economic policy (positive and normative) are distinguished, the sequence of economic analysis of regional policy has been provided. It has been noted that the facts need to be analyzed first, the next step is to analyze the values and the last step is to decide on the course of action by the authorities. It has been determined that there are also time limits for the implementation of the analysis of regional economic policy. Depending on the time of analysis, there are: ex-ante analysis and ex-post analysis. It has been concluded that the effectiveness of further implementation of regional economic policy of the region and the country as a whole will depend on the effective analysis of regional economic policy.

Published: June 2021

In the financial and economic crisis context, which is characterized by an increase in the number of insolvent business entities of the credit market, there are an increase in the share of doubtful loans in loan portfolios of the banks and the issue of studying the assessment of the creditworthiness of borrowers of a commercial bank becomes especially relevant. The article considered various approaches to the interpretation of the essence of the creditworthiness of borrowers and various methods for assessing the creditworthiness of potential customers of banks, such as regression models, neural networks, a classification tree, genetic algorithms, scoring cards, which are the main tools for data mining. Note that the different models can be applied at various stages of assessing a bank's credit risk. The analysis of the assessment of the creditworthiness of borrowers by banks gave grounds to propose a credit-scoring model. The model is presented in the form of a scoring card, which is based on the results of evaluating the logistic regression. Scoring maps are constructed on the assumption that «the past reflects the future». Accordingly, based on data on previously opened loans and analyzing the available information, it is possible to predict the result (behavior) of future borrowers. To create a scoring card, the following business process was considered: the manager of a partner store of the bank fills in the client's personal data, after which the form is sent to several banks for consideration. Banks review the application, obtain information from external sources, and make decisions. The bank, in turn, must quickly and efficiently assess the client and immediately indicate the agreed loan. The scoring model in the form of a scoring card is based on the results of evaluating the logistic regression in the R-Studio software package. The quality of the investigated model was checked by the area under the ROC-curve and the GINI index. According to the results of the study, we can conclude that this model can be included in the automatic decision-making process on the issuance of loans, which will allow banks to 1) reduce the time for a bank to decide to issue a loan; 2) be sure that the loan will be repaid by the borrower; 3) reduce the bank's credit risks.

Authors:   Prydniprovska State Academy of Civil Engineering and Architecture, Kiriukhin Rostyslav
Published: June 2021

Against the background of global transformations and imperatives, it has been considered that countries need to find and form effective public administration strategies. In these circumstances, Ukraine is reforming decentralization in order to optimize the activities of the state apparatus through changes in the administrative-territorial structure and redistribution of powers between central and local authorities. The main tasks for the government are to find effective mechanisms for decentralization strategy and assess their impact on the development of individual territories within the country. The impact of financial decentralization on investment processes in the Dnipropetrovsk region has been analyzed in this article. The stages of decentralization in Ukraine have been considered and the main achievements and tasks of each of them have been highlighted. The regulatory framework, which is the foundation of decentralization reforms in Ukraine, has been described. Indicators of development of united territorial communities (UTC) in Dnipropetrovsk region and Ukraine on the basis of comparative analysis have been considered. Conclusions are made about the leadership of the Dnipropetrovsk region from the results of reforms. The dynamics of revenues and expenditures of local budgets of the Dnipropetrovsk region for the period 2014-2019, as well as the change in the amount of funds by accounts have been analyzed. It has been concluded that there is a surplus and budget deficit in the specified period. The dynamics of capital investments of the Dnipropetrovsk region for the period 2014-2019 has been given and the structure of their financing at the expense of the state and local budgets has been analyzed. Conclusions are made regarding the positive impact of financial decentralization on investment processes in the Dnipropetrovsk region. According to the analysis of financial decentralization of the Dnipropetrovsk region, the reforms led to an increase in local budgets and capital investments, an increase in the share of capital investment financing from the state and local budgets, and led the region to leadership in a number of UTC indicators. Thus, it can be argued that decentralization has had a positive impact on the Dnipropetrovsk region and contributed to the strengthening of its socio-economic processes and investment activity.

Invihsibles. Trajectoires de femmes séropositives
Authors: Fargnoli Vanessa
Published: June 2021

Les femmes séropositives n’appartiennent pas à des groupes cibles tels que définis par l’Office fédéral de la santé publique suisse. Elles constituent donc un groupe de personnes invisibles, absentes des débats publics et médicaux, non considérées dans la littérature scientifique en général et non intégrées dans les recherches cliniques. Pour combler cette lacune, ce livre présente et analyse trente récits de vie récoltés entre 2013 et 2016 auprès de femmes hétérosexuelles séropositives en Suisse romande, qui ont été diagnostiquées positives au VIH avant l’an 2000. Ces entretiens ont permis de revisiter presque quarante ans d’histoire du VIH/sida sous un angle critique féministe.

Pertanian menjadi sumber mata pencaharian utama di sebagian  masyarakat pedesaan Kabupaten Purwakarta. Daya dukung lahan harus sangat diperhatikan karena  berpengaruh dengan  keberlangsungan kehidupan dan  kesejahteraan manusia. Analisis daya dukung lahan pertanian dapat memecahkan masalah perubahan lahan dan ketahanan pangan. Penelitian ini akan membahas mengenai perhitungan kebutuhan lahan pertanian di Kabupaten Purwakarta berdasarkan perhitungan proyeksi penduduk 10 tahun ke depan, dengan menggunakan data pada tahun 2018. Metode yang digunakan dalam penelitian ini yakni dengan metode deskriptif kuantitatif. Proses pencarian, pengumpulan, dan analisis data dilakukan dengan menggunakan studi kepustakaan dari berbagai sumber terpecaya. Teknik analisis yang digunakan untuk menentukan daya dukung lahan pertanian mengunakan rumus matematika dari konsep gabungan atas teori Odum, Christeiler, Ebener Howard, dan Issard dalam Soeharjo dan Tukiran (1990) dalam Moniaga (2011), perhitungan Jumlah Penduduk Optimal (JPO), dan perhitungan Kebutuhan Lahan Pertanian (KPLR). Hasil dari penelitian ini adalah Peta KLPR 2028 yang menunjukan hasil tingkat daya dukung lahan yang bervariasi yang disebabkan oleh faktor data luas panen, produksi, dan jumlah penduduk pada tiap kecamatan tergantung pada komoditasnya. Hasil perhitungan jumlah penduduk optimal (JPO) di beberapa kecamatan Kabupaten Purwakarta apabila disesuaikan dengan komoditasnya masih lebih sedikit dibandingkan dengan jumlah penduduk yang terdata pada masing-masing kecamatan. Hasil perhitungan kebutuhan lahan pertanian dari perhitungan JPO 2028 dan KPLR 2028 yang menunjukan bahwa kecamatan Jatiluhur, Maniis, Sukatani, Purwakarta, Babakancikako, Campaka, dan Bungursari tidak bisa menjadi wilayah swasembada pangan pada tahun 2028. Sedangkan untuk kecamatan yang lain masih bisa menjadi swasembada pangan untuk 2028 karena kebutuhan masih dapat terpenuhi dari luas lahan panen yang ada

Morphofunctional changes in cells of Tetrahymena pyriformis W infusoria under the influence of plant growth regulators — derivatives of pyridine-n-oxide
Authors: Vasetska OP
Published: June 2021

The aim of the Research. To identify morphological changes in Tetrahymena pyriformis W infusoria under the acute exposure to plant growth regulators (PGR) — derivatives of pyridine-N-oxide and compare them to functional disorders of cells.

Materials and Methods. In the research we used the 2-methylpyridine-N-oxide, 2,6-dimethylpyridine-N-oxide and their complexes with organic acids (succinic, maleic) or metal salts (ZnCl2, ZnI 2, CoCl2, MnCl2) (a total of 15 substances), synthesized at the Institute of Bioorganic chemistry and Petrochemistry, NAS, Ukraine. Studies were performed on Tetrahymena pyriformis W infusoria in isotoxic doses — at the level of toxic concentrations — LC50, LC16 and inactive concentrations (LC0). Morphological changes in cells of infusoria were assessed visually with the use of a light microscope. Structural changes in infusoria were compared to functional changes in cells (motor activity and energy state) obtained under the same experiment.

Results and Conclusions. It is demonstrated that 2-methylpyridine-N-oxide, 2,6-dimethylpyridine-N-oxide and their complexes with organic acids (succinic, maleic) or metal salts (ZnCl2, ZnI2, CoCl 2, MnCl2) cause functional and morphostructural changes in infusoria, the extent of which depends on the current concentration. Morphostructural changes in infusoria under the influence of the studied PGRs are characterized by a change of shape, growth of the contractile vacuole, vesiculation, damage to the integrity of the cytoplasmic membrane, emission of cytoplasm and structural elements of cells into the nutrient medium.

Complexes of methyl derivatives of pyridine-N-oxide with metal salts in the studied concentrations reduce speed and increase energy expenditure on movement, cause changes in behavioural reactions and structure of cells to a greater extent than 2-methylpyridine-N-oxide, 2,6-dimethylpyridine-N-oxide and their complexes with organic acids. Both functional and morphological changes in infusoria are more evident under the influence of studied PGR occurring at concentrations corresponding to LC50. At lower concentrations the changes in the functional activity of infusoria were observed. Comparison of the obtained functional and morphostructural indicators of the state of infusoria shows that complexes of methyl derivatives of Pyridine-N-oxide with metal salts have more toxic effects on infusoria than complexes of methyl derivatives of pyridine-N-oxide with organic acids. Reduced motor activity and an increase in energy consumption per a unit of a path of motion, together with the morphological changes of cell structure, are the indicators of toxicity of xenobiotics for infusoria and criteria for assessing their viability.

Key Words: methyl derivatives of Pyridine-N-oxide, Tetrahymena pyriformis W, morphofunctional changes.

RECYCLING TECHNOLOGY OF ACTIVE MATERIALS OF THE ZINC-MANGANESE CURRENT SOURCES

Published: June 2021

It is being investigated whether it is possible to develop a low-cost method for processing used Zn-MnO2 primary chemical power sour­ces, which is focused on a closed cycle of ge­nerating zinc-manganese power sources from wasted batteries. It is proposed that chemical processing reagents be replaced with less dangerous ones for the environment and people, in accordance with «green chemi» principles. The existing hydrometallurgical method of processing of primary current sources with selective extraction of the spent part of the anode mass is modified and laboratory processed. The stage of additional extraction of arsenic is entered. The proposed technological scheme avoids heavy air loads in the form of carbon dioxide emissions by eliminating the stage of burning organic matter. The use of acetic acid allows to avoid sulfuric acid discharges and to obtain high-quality for secondary production of cathode mass of new chemical current sour­ces, as well as to obtain technical zinc powder and active zinc powder using hydrometallurgical technology for anode mass production of primary batteries. Also, the presence of stages of extraction of heavy metal ions (Hg2 +, Pb2 +, Cd2 +) and Arsenic to obtain products that can be further used in other technological processes makes this technology virtually waste-free, and in the stages of recovery of acetic acid and hypochlorite – closed. Thus, the use of the proposed technological schemes allows to make such production not only a little harmful to the environment, but also for workers, as well as to simplify the requirements for technological equipment.
Fabrication of WC-Graphene-Al Composites by Rapid Sintering and Their Mechanical Properties
Authors: Shon In-Jin
Published: June 2021

Tungsten carbides are very attractive because of their superior properties, e.g., high thermal and electrical conductivities, high melting point, high hardness, and relatively high chemical stability. Tungsten carbides with a binder metal, for example Ni or Co, are mainly used to fabricate nozzles, molds and cutting tools in the composite form. Al has been reported as an alternative binder in Tungsten carbide since Al shows a higher oxidation resistance than Ni or Co and is less expensive. Nanostructured WC-Graphene-Al composites were sintered rapidly using pulsed current activated sintering (PCAS). The mechanical properties (hardness and fracture toughness) and microstructure were investigated using scanning electron microscopy and Vickers hardness tester. The PCAS method successfully obstructed grain growth, resulting in nanostructured materials, and induced a very fast consolidation nearly at the level of theoretical density. The grain size of WC in WC-Graphene-Al composite decreased with the addition of Al content. The fracture toughness and hardness of the WC-5vol.% graphene-x vol.% Al (x=0, 5, 10, 15) were 4.7, 5.5, 5.9, 7.9 MPa·m1/2 and 2008, 1961, 1883, 1731 kg/mm2, respectively. The fracture toughness was improved without remarkable decrease of hardness due to the small dimensions of the WC grain and the consolidation facilitated by adding Al to WC-Graphene matrix.
