Opportunities and risks of the climate policy in Russia
Authors: Porfiriev B. N. , Shirov A. A. , Kolpakov A. Y. , Edinak E. A.
Published: January 2022

The climate agenda involves significant economic dimension and component. This is precipitated, on the one hand, by the climate change impact on the economy and its implications for economic development that necessitate costs for planning and implementing adaptation measures, and, on the other hand, by the imperatives of structural and technological modernization of the economy to strengthen its competitiveness and sustainability of socio-economic development including reduction of industrial greenhouse gases (GHG) emissions and increasing the ecosystems’ carbon sink capacity. The above implies harmonization of ecological, climatic, socio-economic, and technological characteristics to produce an effective national low GHG emissions socio-economic development strategy required by the Paris Climate Agreement. This in turn calls for comprehensive assessment of the impact produced by new low-carbon technologies on economic dynamics using the framework of macrostructural calculations and scenarios of economic development of Russia with different volumes of funding invested in decarbonization. It is argued that the most efficient is a group of so-called moderate scenarios that provide for both GHG reduction and economic growth rates above the global average. More ambitious scenarios involve risks of slowing GDP growth given weighty additional investment which constrains the dynamics of household consumption. The key role of the Russian ecosystems capacity to absorb and sequester carbon in implementation of the low GHG emissions socio-economic development strategy is substantiated and the imperative for the complex of measures to improve the efficiency of land use and forestry resources (LULUCF), primarily the quality of R&D and the national monitoring system development, is emphasized.
Effect of main cultivation methods in dry rainfed conditions on the amount of weed under winter wheat
Authors: Feyzullayev H. M.
Published: January 2022

Relevance. Against the background of predecessors, soil cultivation and nutritional conditions, weeding of the area under Barakatli 95 durum wheat variety was studied and the results obtained are given in the article. Thus, high weeds in the field reduce the quantity and quality of crops. One of the main factors preventing this is the application of proper cultivation methods appropriate to the region. This is one of the most important and urgent issues in agriculture.

Methodology. The research was conducted in a 3-factor (2×3×3) field experiment in a short-rotation crop rotation (pea-wheat-wheat) located at the Jalilabad Regional Experimental Station in the rainfed conditions of South Mugan. The amount of weeds in the field was studied in the first decade of March and April by counting weeds per 1 m2 from different parts of the field according to the options.

Results. The results of the 3-year study (average for 2019–2021) showed that the effect of predecessors, soil cultivation and nutritional conditions on the amount of weeds under winter wheat was different. Among the cultivation options, relatively high weeding soil was obtained with a heavy disc harrow at a depth of 10–12 cm in the form of 1 disc, and against the background of feeding conditions, N60P60 + 10 tons of manure on all three cultivations, and the least weeding was observed in the variant where N90P60K45 fertilizer norm was applied in 2 discs at a depth of 10–12 cm with a heavy disk trowel after the pea predecessor.
New technological solutions for restoring the inner surface of hydraulic cylinders
Authors: Chavdarov A. V. , Tolkachev A. A.
Published: January 2022

Relevance. Agricultural machines widely use hydraulic cylinders for various auxiliary and working movements. Operation in harsh field conditions leads to the failure of the hydraulic cylinder mirror and, as a result, to the loss of force on the cylinder rod. The development of technological solutions for the restoration of the inner surface as a more appropriate solution in repair production is relevant.

Methods. Studies of the heat flow using the “Fluke Ti32” thermal imager and ofthe influence of gas-dynamic spraying (GDS) modes on the adhesive and cohesive strength when using a new design of the nozzle part of the GDS equipment were carried out.

Results. The suitability of usage of new nozzle design for GDS in order to restore the inner surface of the hydraulic cylinder body has been established. The elongated and curved nozzle for installations of the “Dimet” type practically does not change the temperature regime of spraying. The adhesive and cohesive strength of the coatings obtained with the new nozzle design is sufficient to operate under conditions characteristic of the inner surface of the hydraulic cylinder body.
Assessment of the degree of lameness in cows
Authors: Kontsevaya S. Yu. , Nefedov A. M. , Lutsay V. I. , Lavrov S. I. , Pekurovsky D. A.
Published: January 2022

Relevance. The structure of the hoof of cows is a complex biological mechanism consisting of the hoof joint, hoof bone, finger pad, sole, hoof wall, etc. According to V.A. Lukyanovsky (1982), hooves are an additional heart of the animal, since when the hoof hits the ground, the blood actively rises, which allows to create auxiliary pressure in the blood vessels, facilitating the work of the heart muscle. When this system is violated, pathologies of the cardiovascular system often develop. The appearance of foci of the pathological process in different parts of the hoof will not only disrupt the work of the heart, but also cause discomfort, pain, and most importantly — lameness, which will be the driving force in a significant decrease in the productivity of cattle.

Methods. Scientists identify three main signs of developing lameness in an animal. The first is the position of the back when walking, normally the back should be smooth and straight, while with the onset of lameness, the animal will carefully rearrange the limb, thereby straining the dorsal muscles, after which a bend in the back will be observed. The second sign is a short step, since with pain syndrome, the animal tries to minimize the load on the diseased limb. The third sign will be the obvious protection of the diseased limb, as a result of which the animal will completely cease to rely on the limb, both when walking and when standing.

Results. A systematic approach will allow us to present a mathematical model of a healthy animal and of lame one. Thus, the following pattern can be identified: In order to receive nutrients together with the feed, the cow must reach the feeder, therefore, depending on the degree of lameness, there is a decrease in the consumption of dry matter, up to 15%. Based on this, it can be calculated that with a lack of nutrients and energy, there will be a decrease in milk yield of up to 36%. Which, according to P.I. Nikanorov and I.M. Kasyanov, will lead to a loss of up to 300 kg of milk for the entire lactation period. It was found that in the presence of overgrown and deformed hooves, the daily milk yield of cows is reduced by 5–12%, and with the appearance of cracks in the fragments of the horny capsule — by 19–20%. Also, the birth of a calf is required to obtain milk, and the presence of lameness will negatively affect the production of reproductive hormones, lead to the appearance of “quiet” hunting, which in turn will indirectly lead to a loss of milk productivity.

A REVIEW OF MICROSTRUCTURE AND CORROSION BEHAVIOR OF CU AL NI SHAPE MEMORY ALLOY
Authors: Mohammed Dawood Nawal
Published: January 2022

The shape memory alloys (SMAs), that consist of Cu-Al-Ni, have been established and developed for the applications used at higher temperature values due to their capability to return to its original shape when heating close to its transformation temperature. Cu-Al-Ni alloy has high value of transformation temperature and show small hysteresis as compared to the other types of SMAs. This work present a general review about how SMAs have developed by adding several metals such as, Ti, Be, B, Mn, and Zr or by changing its content (Ni or Al) by either decreasing or increasing. That might show a significant impact on the phase transition and enhancing the corrosion behavior and mechanical properties of the presented alloys. However, the transformation of the martensite phase is the critical factor that might change the properties of Cu-Al-Ni SMAs. This phase is largely affected by addition of the alloying element mentioned above. A review about effect of addition some alloying elements for enhancing the corrosion characteristics of the alloy and phase transition is presented.

Authors: Siregar Iskandarsyah , Zulkarnain
Published: January 2022

Conflict and social change are a couple that influences each other. Conflict inevitably drives social change. Social changes also inevitably lead to conflict. These conditions can manifest in large or small sizes. Every society that exists on this earth in their life will certainly experience what is called changes. The existence of these changes will be known if we compare by examining society at a particular time which we then compare with the state of society in the past. Changes that occur in society are a continuous process. This situation means that every society will, in fact, experience changes. This study aims to collect argumentative views on the relationship between conflict and social change. The conclusions of this study have a significant impact in providing illustrations and projections of what social situations occur before and after conflicts or social changes occur. This research is a discourse relation analysis research. This type of research analyzes the relationship between two or more variables and then describes each contextual factor. This study concludes that the argumentative view of implying and exposing the relationship of conflict to social change is vital and sensitive.

Authors: Zulkarnain  , Indrayani Irma
Published: January 2022

This study discusses the effect of China's economic revival on Indonesia's foreign policy orientation. Historically, the relationship between China and Indonesia, which had been severed in 1965 due to ideological conflicts and Indonesia's suspicion of China's support for the Indonesian communist party (PKI), has now been re-establish since the 1990s, which began with China's economic growth. Foreign policy is often caused by a combination of unexpected external forces with unfavorable structural factors. The continued stalemate in China-Indonesia bilateral relations has equally serious consequences for China. China's diplomatic failure against Indonesia has cost China, and that loss cannot be offset by the diplomatic gains generated by the opening of new relations with other ASEAN countries. This study tries to discuss this situation in depth using several approaches to find two variables that become the topic of this thesis: the rise of the Chinese economy and its influence on Indonesia's foreign policy. This research found that Indonesia's bilateral relations with China under the leadership of President Susilo Bambang Yudhoyono ran normatively and without significant fluctuations.

Published: January 2022

As initially, Australia supported the integration of Timor Leste into the Republic of Indonesia, many events occurred which caused the relationship between Indonesia and Australia to be slightly disturbed. The changes that have taken place in Australia's relationship with Indonesia illustrate the real effects of Timor-Leste's independence. As a result of Australia's role in the East Timorese independence process, its relationship underwent many changes, especially in the political and military fields. The changes taking place in military relations are evident. The Agreement on Mutual Security (AMS) was released, the joint training was canceled, and the troops that used to work together became enemies. Eventually, Australian arms sales to Indonesia were stopped. Changes in the political and diplomatic sphere, including all political visits, were canceled, and politicians within Australia and Indonesia publicly denounced others. Furthermore, cooperation within the global framework is limited, and the Ambassador's 'high alert' status is. Overall, Australia's relations with Indonesia became hostile. This study aims to determine how the influence of Australian foreign policy on Indonesia after the independence of Timor Leste. This research shows that the independence of Timor Leste and Australia's role in this process directly influenced government relations between Australia and Indonesia. Most Indonesians view the Australian government's actions and policies as separate from its relationship with Australian citizens.

An Analysis on the Impact of Natural Disasters on the Economy of the Philippines
Authors: Bringas Bea , Bunyi Lance Jared , Manapat Carlos L.
Published: January 2022

Over the past century, natural disasters have been terrorizing the economy by causing human fatalities and damaging infrastructure and production inputs. The Solow growth model suggests that natural disasters adversely affect gross domestic product (GDP) since these disrupt the production of inputs. On the contrary, the Schumpeterian growth theory provides an explanation behind the positive effect of natural disasters on economic growth. This study analyzed the relationship between natural disasters (i.e. earthquake, flood, and storm), economic activities (i.e. foreign aid and foreign direct investment) and GDP per capita income in the Philippines from 1990 to 2019. This study employed a multivariate analysis, time series regression, and autoregressive distributed lag (ARDL) approach. The results revealed a complex relationship between GDP per capita and the regressors. In the short run, the independent variables have a negative and significant relationship with the country’s per capita income. On the contrary, only FDI has a significant long-run relationship with the economy of the Philippines. The results highlight the Philippines’ need for comprehensive disaster plans and to lessen its dependence on foreign and external factors.

SOCIAL ENTREPRENEURSHIP DAN CORPORATE SHARED VALUE UNTUK PEMBERDAYAAN PETERNAK SAPI PERAH
Authors: Teguh Monika , Sitepu Sri Nathasya Br , Wiwiek Wiwiek , Tanaka Priscylia
Published: January 2022

Peternakan sapi merupakan salah satu sub-sektor yang berperan penting bagi masyarakat Indonesia. Selain karena usaha peternakan sapi mendorong perekonomian masyarakat di wilayah-wilayah pedesaan, peternakan sapi juga penting dalam menjaga ketahanan pangan nasional. Sayangnya masih banyak peternak sapi rakyat yang hidup pra-sejahtera. Maka dari itu diusung dua buah konsep yang saling berkesinambungan untuk mengatasi permasalahan para peternak sapi rakyat. Konsep pertama adalah social entrepreneurship Â di mana para peternak dapat membentuk suatu social entreprise bersama untuk meningkatkan daya saing mereka di pasar. Dengan konsep ini, para peternak rakyat dapat menyatukan sumber daya yang mereka miliki dalam satu organisasi yang terstruktur dan memiliki legalitas yang lebih kuat. Jika dalam membentuk social entreprise ini para peternak mengalami kesulitan modal, maka mereka dapat menggunakan konsep kedua yaitu creating shared value (CSV). CSV merupakan konsep di mana perusahaan yang bermodal kuat bergandengan dengan social entreprise, bukan hanya untuk mendukung social entreprise itu, namun juga untuk berbagi nilai yang saling menguntungkan. Dengan adanya kerjasama jenis ini, social entreprise dapat berkembang tanpa ketakutan akan kurangnya modal, sedangkan perusahaan pemodal bisa memperoleh keuntungan seperti pasokan bahan baku, pembagian keuntungan, maupun peluang usaha baru. Konsep-konsep ini telah dilaksanakan di negara berkembang lain seperti India dan memberikan dampak positif. Maka dari itu diharapkan konsep-konsep ini juga dapat dijalankan di berbagai wilayah di Indonesia dengan dorongan dari pemerintah, institusi pendidikan, maupun organisasi nirlaba.

En el marco de las discusiones sobre las complejas condiciones en las que operan las escuelas multigrado en México, y de la evaluación a la política multigrado realizada por el desaparecido Instituto Nacional para la Evaluación de la Educación, este trabajo muestra las necesidades de formación de los profesores de preescolar y primaria que laboran en contextos multigrado veracruzanos. A partir de un cuestionario con preguntas abiertas y de opción múltiple aplicado a 156 profesores que en el ciclo escolar 2019-2020 laboran en aulas multigrado, se analizan las necesidades de formación sentidas. Los resultados muestran que solo 55% de los docentes han participado en espacios de formación para trabajar en entornos multigrado. Además identifican que las necesidades de formación más reiteradas son: la planificación didáctica para trabajar en aulas multigrado y las estrategias de enseñanza en multigrado (tanto a nivel general como sobre contenidos específicos de español y matemáticas). En la discusión se destaca la importancia de fortalecer la formación continua de los profesores que laboran en estos contextos como parte de una comprensión más amplia del desarrollo profesional docente y en tanto no exista una formación inicial acorde con las prácticas de enseñanza que ahí se desarrollan.

Introduction: Soil-transmitted helminthiasis (STH) is common in areas with poor sanitation. In Indonesia, the prevalence of the disease is still high ranging from 16–72%, despite the elimination efforts that have been done. This study aimed to determine the prevalence of STH, nutritional status, and hemoglobin levels of elementary school-age children in of slum area in Makassar. 

Methods: This was an observational study with a cross-sectional approach. Subjects were 33 elementary school-age children in one of the slum areas in Makassar, South Sulawesi, Indonesia. Stool samples were collected and examined using the Kato-Katz method. Hemoglobin levels were examined with the Azidemet hemoglobin method using capillary blood samples. Assessment of nutritional status was carried out anthropometrically using weight for height, height for age, and body mass index (BMI) for age as indicators.

 

Results: The prevalence of STH in this study was 27%, all of them had low nutritional status. As many as 15% and 45% of subjects were severely wasted and wasted, respectively, based on the weight for height indication, 61% were wasted based on the BMI for age indicator, and 12% were stunted based on the height for age indicator.  Ten percent of the subjects had low hemoglobin levels, none of them had STH.

Conclusion: The STH prevalence of school-age children in one of the slum areas in Makassar is still high. Subjects with STH also experienced low nutritional status.

Background: The oral is the gateway for the entry of various kinds of microorganisms into the body, with the prevalence of people having dental and oral problems in Indonesia increasing every year. The normal flora of the oral acts as a body defense, but it can cause disease due to predisposing factors, namely oral hygiene. Therefore, it is necessary to find an alternative in maintaining oral health. Islam is a religion that emphasizes personal hygiene, such as performing ablution.

Content: The types of bacteria found in the oral before ablution was 33.33% Pseudomonas sp., 6.67% Lactobacillus sp., 3.33% Streptococcus sp. and 0.14% Staphylococcus sp. while the types of bacteria found in the oral after ablution were 26,8% Pseudomonas sp., 20% Lactobacillus sp., 5% Streptococcus sp. and 2% Staphylococcus sp.

Conclusion: There was a change in the number of bacteria, namely an increase in gram-positive bacteria in the oral after ablution.

The article deals with the actual problem of theoretical substantiation of the method of identification (diagnosis) of metal inclusions (hereinafter referred to as metal inclusions) in bulk raw materials under the conditions of a conveyor belt. The presence of metal inclusions in the raw material transported by the conveyor belt can lead to both emergencies and deterioration in the quality of the output product. The identification method provides for diagnosing the presence of metal inclusions, determining its dimensions, type of metal and coordinates relative to the cross-section of the conveyor belt. The results of theoretical and experimental studies of the method for identifying metal inclusions based on a scanning signal and an additional excitation coil are considered. A mathematical model has been developed for determining the position of metal inclusions on a conveyor belt relative to a line perpendicular to the axis between two excitation coils, including two trajectories for determining coordinates for three excitation coils and two receiving coils.
Separation of the 3D stress state of a loaded plate into two-dimensional tasks: bending and symmetric compression of the plate

The three-dimensional stress-strain state of an isotropic plate loaded on all its surfaces is considered in the article. The initial problem is divided into two ones: symmetrical bending of the plate and a symmetrical compression of the plate, by specified loads. It is shown that the plane problem of the theory of elasticity is a special case of the second task. To solve the second task, the symmetry of normal stresses is used. Boundary conditions on plane surfaces are satisfied and harmonic conditions are obtained for some functions. Expressions of effort were found after integrating three-dimensional stresses that satisfy three equilibrium equations. For a thin plate, a closed system of equations was obtained to determine the harmonic functions. Displacements and stresses in the plate were expressed in two two-dimensional harmonic functions and a partial solution of the Laplace equation with the right-hand side, which is determined by the end loads. Three-dimensional boundary conditions were reduced to two-dimensional ones. The formula was found for experimental determination of the sum of normal stresses via the displacements of the surface of the plate.

High-strength steels are widely used in the defense and civil industries. During operation, high-strength and armored steels are subjected to extreme static and dynamic loads. Material specimens or full-scale structures testing at such loads is a very complex and expensive process. Therefore, numerical calculation methods are commonly used to assess their strength. To determine the parameters of these models as an express method, it is reasonable to use tests that are similar in nature of the loading, deformation, and failure to full-scale or standard ones, but which are cheaper and easier to perform in the laboratory conditions. One of the key properties of high-strength steels is their resistance to penetration by various types of armor-piercing strikers. To simplify the testing procedure and minimize materials consumption, static and dynamic punching methods have been developed. A set of experimental and numerical investigations on the deformation of various specimens from high-strength steels has been made under static and dynamic load conditions, in particular, plate specimens punching (punches of different shapes) by the G. S. Pisarenko Institute for Problems of Strength of the NAS of Ukraine. This paper presents the experimental procedure and equipment for the investigation of the materials’ behavior under static punching. High-strength steel plate specimens have been tested on an upgraded servohydraulic machine Instron 8802 using three types of punches: flat, spherical, and conical. It is established that the diagram describing the spherical punching is the most informative, while the diagram showing the conical punching is less informative. The nature of the specimen fracture is consistent with the results of field tests in the barrier penetration by armor-piercing strikers. The obtained results are in good agreement with the known literature data and can be used to validate the results obtained by numerical simulations.
