Theoretical Substantiation of the Traction Resistance of the Ridge Seeder
Authors: Zykin Evgeniy S.
Published: February 2022

The analysis of the current state of the enterprises of the agro-industrial complex of Russia has shown that various energy-saving cultivation technologies of agricultural crops, including row crops on ridges, are being applied on a large scale. Mainly, such technologies imply a reduction in the number of technological operations performed, the replacement of sowing on pre-treated soil with sowing according to minimal technology or no-till at all. When implementing comb sowing of row crops, the problem of energy saving remains relevant. Keeping in mind the design features and the operation principle of tillage rollers, it can be stated that they are designed mainly for the destruction of soil lumps and compaction of soil on a flat field before or after sowing. There is a problem of high-quality rolling of soil ridges formed simultaneously with the sowing of row crops. (Research purpose) The research purpose is to substantiate the traction resistance of a roller aggregated with a combed roller theoretically. (Materials and methods) The algorithms used to assess the quality of the rollers are imperfect, for reliable justification of the optimization parameter, it is necessary to solve a number of issues, in particular, the methodology for determining the traction resistance of rollers designed for the final creation of soil ridges by simultaneous action of spherical disks and conical wheels on their sides. A skating roller has been developed for the finishing operation of forming a soil ridge with the required parameters and density simultaneously with sowing, the novelty of which is confirmed by patents of the Russian Federation No. 194330, No. 194348, No. 196712. (Results and discussion) The article presents the process of forming a soil ridge by a roller, and the justification of the traction resistance of a ridge drill roller. A vertical load artificially created by a spring additionally acts on the roller of the comb seeder, this load evenly spreads to the conical core and spherical disks of the roller. (Conclusions) The total traction resistance of the roller of the comb seeder is affected by the weight of the conical wheel, frame, additional spring compression load, the size of the rolling wheel and spherical discs, the speed of the roller, as well as the physical and mechanical properties of the soil.

Authors:   Voronezh State Agrarian University named after Emperor Peter the Great, Sudakov Aleksandr N.
Published: February 2022

Digitalization of technological processes makes it possible to optimize the cost for the poultry products. The low level of digitalization in determining the state of the poultry livestock is due to a significant amount of organoleptic research in the work of a zootechnician-poultry breeder. The absence of numerical indicators of controlled parameters entails a subjective assessment, limits the amount of information when transmitting data via electronic communication channels, complicates the process of training specialized personnel, reduces the efficiency of resources consumed (feed, heat and electricity, and others). (Research purpose) The research purpose is to study the prospects of digitalization of the functions of zootechnics in the optimization of technological processes of poultry farming. (Materials and methods) For the research, there were used documentary research, data analysis, and search experiments. (Results and discussion) The shortcomings of existing methods of determining the quality and comfort of livestock maintenance and its condition were revealed by the example of current recommendations on the content of highly productive meat of cross chickens. The following components of keeping poultry have the potential for optimization: maintaining the microclimate in the poultry house, veterinary care, wages, repair of fixed assets. The large amounts of digital data obtained by instrumental means for monitoring zootechnical indicators of poultry have the wide using possibilities. (Conclusions) The article presents a list of technical analogues of organoleptic control methods based on the use of thermal imaging equipment, video analytics, acoustic sensors, indirect signs using traditional technical control data. The article proposes an algorithm for processing large data arrays, which allows to increase the optimization of technological processes. Described modern technical solutions in the field of agricultural automation have wide prospectives.

Terdapat silang pendapat dari para manajer dan eksekutif perusahaan baik di Indonesia maupun di Luar Negeri mengenai pemberian bonus dengan bentuk  program saham karyawan/employee stock ownership program untuk meningkatkan motivasi dan mendongkrak kinerja karyawan dengan tujuan agar memaksimalkan profit (maximizing company profit). Terlebih bagi karyawan yang sudah mendekati usia pensiun, sering terlihat bahwa mereka lebih mengutamakan kebahagian dan kesejahteraannya dan tidak terlalu mengutamakan peningkatan motivasi dan kinerja. Hal ini dikarenakan untuk mencapai kinerja yang baik, memang diperlukan kerja keras yang ekstra. Mereka sering berpikir lebih ke masa pensiunnya dimana mereka akan mendapat suatu dana pensiun. Penelitian ini mencoba menggali kondisi suatu perusahaan di Indonesia dan kemungkinan2 apa saja yang dapat  meningkatkan motivasi dan kinerja para karyawannya, baik yang masih usia produktif ataupun yang sudah mendekati usia pensiun.There is pros and cons amongst managers and executives around the world including in Indonesia regarding incentives such as ESOPs – Employee Stock Ownership Programs (as an alternative bonus) to boost employees motivation and performance which in turn to achieve company’s target of profit maximization.  Moreover to the near pension employees, often come across that they prioritizing their happiness,  well being and enjoying life without being burdened with company target which is translated to excessive work load. They tend to focus on their pension plans since they will get their pension funds which can be used for vacation or other activities and plans. This research tries to get the feel and condition of the Indonesian company and try to find out whether bonus (or other form of incentives) can boost motivation and performance of all employees (across all ages)

Performance Evaluation of Surface Roughness in the Boring Operation of IS 2062 E250 Plate on CNC Machine Using Combined Entropy-Decision Tree-VIKOR Approach
Authors: Abiola Isaac Temitope , Oke Sunday Ayoola
Published: February 2022

In boring E250 B0 steel material, the selection of process parameters is one of the most challenging tasks to achieve. The boring literature lacks understanding and fails to reveal how to select the important boring parameters for utmost resource distribution to the most important parameters. This article proposes a novel method to analyse the importance of parameters in boring to produce utmost surface roughness using the entropy-decision tree-VIKOR approach as a multi-criteria decision-making solution to the choice of process materials for superior surface roughness. The choice parameters include speed, depth of cut, feed and nose radius. The entropy approach was instituted to attain the weight of the diverse parameters. The decision tree approach is deployed through the classification of the parameters as beneficial and non-beneficial and the expected values at each mode evaluated. The desirable weightage is then established and serves as the input to the VIKOR approach. This converts the desirable weightage into unit measures through the best/worst value and weightage evaluation. The individual regrets are then analyzed and the final ranking obtained. Results revealed that the depth of cut is the most important parameter, then nose radius (0.98), feed (0.307) and speed (0), respectively. Therefore, a plan to assign more measures to the depth of cut may be developed and the least resources may be assigned to speed. This detail may be helpful to prepare the annual budgets for the boring operation on the factory floor.

The prevailing literature and empirical studies on organizational performance management stress the increasing importance of non-financial performance measures and propose companies implement an integrated performance measurement system. The purpose of our research is to investigate the characteristics of performance measurement and management in various industries. This paper discusses the published literature related to the Performance Pyramids System (PPS), focusing on the latest progress in the 18 years, starting from 2002 until 2020. This paper involves the study review of 50 articles related to PPS implementation of available database search, including Google Scholar, Elsevier, Science Direct, and other publishers in the world. This literature review contains results from a variety of different perspectives. The perspective includes the industry's focus, the focus of the number of distribution by country, the year of publication, and the number of publishers. This is useful for all types of manufacturing industries to find solutions to problems. The paper also provides advantages for researchers next to add to the literature. The aims of this study are: (i) to identify the most discussed approaches in the literature to evaluate the organizational performance, and (ii) to carry out a diagnosis of how small and medium enterprises with economic activity in several countries measure and operationalize the evaluation of their performance. To meet the study's objectives, we analyzed published studies in scientific journals and conducted twelve interviews in SMEs. The results indicate that, in addition to the majority of the studied organizations not having a formal process of their strategy, they also do not measure their products in an integrated system that would allow them to evaluate according to their strategic goals.
LA UNIVERSIDAD EN LA GÉNESIS DE LA CONCIENCIA NEGRA EN SUDÁFRICA
Authors: Abreu Veranes Luis Edel
Published: February 2022

El origen del Movimiento de la Conciencia Negra en Sudáfrica está relacionado con los acontecimientos ocurridos al interior de las universidades sudafricanas, especialmente la situación del estudiantado negro. Situación que se articula perfectamente con las estructuras segregacionistas profundizadas por el régimen del apartheid en Sudáfrica a partir de 1948. En ese sentido se formulan determinadas interrogantes que salen a la luz en el proceso investigativo principalmente sobre esa relación que favoreció el origen del connotado movimiento. Para tratar de dar respuesta a ese fenómeno se manejaron variables propuestas y una metodología analítica e histórica-lógica, cuya intención es demostrar el impacto de la evolución de la educación bantú y la importación al sector educacional de las propuestas segregacionistas que crearon condiciones muy desiguales para el avance de los estudiantes, en función de su origen etno-racial, como parte de la estrategia de bantustanización del apartheid. En esa dirección se formaron un grupo de estudiantes, que para los años sesenta había nacido o crecido con el apartheid y que se encontraban doblemente segregados dentro y fuera de la Universidad, pero también influenciados por el proceso de descolonización africano, la represión del régimen en los años sesenta y los movimientos sociales que tuvieron lugar a nivel internacional. Para concluir que todas aquellas condiciones externas e internas, estructurales y circunstanciales condujeron al nacimiento del Movimiento de la Conciencia Negra en Sudáfrica, con una relativamente novedosa plataforma ideológica en el escenario de lucha sudafricano.
MANAGING POLITICAL IMPASSE THROUGH DIALOGUE: A VALIDATION OF CLIENTELISM IN AFRICA
Authors: Mbombo Jean-Marie Kasonga
Published: February 2022

Impasses políticos ocorrem cada vez que um líder africano viola acordos de paz, organiza eleições ou altera a constituição do país para permanecer no poder indefinidamente. Em um estilo moderno, o partido governante recorreria a uma ferramenta política de diálogo nacional para recuperar a legitimidade perdida e, ao mesmo tempo, manter o controle do poder. Usando a República Democrática do Congo (RDC) como um estudo de caso típico de clientelismo de elite, este artigo analisa o apelo ao diálogo nacional iniciado pelo ex-Presidente da República Democrática para discutir o futuro do país ao final de seu mandato constitucional em 2015. Baseia-se em dados secundários (revisão da literatura existente) e adota um quadro teórico do neopatrimonialismo para abordar a questão se o apelo ao diálogo nacional pretendia gerar soluções inovadoras para os problemas perenes de governança congoleses ou para legitimar a continuação do regime mediante a recompensa de alguns simpatizantes do regime com nomeações políticas. Como alternativa a um diálogo infrutífero, o estudo destaca a vontade política sob a nova liderança do presidente Felix Tshisekedi, que vem desmantelando gradativamente o antigo regime na RDC.

A compreensão sistemática da China e a pesquisa da África começaram na Nova China, que pode ser dividida em três etapas. O apoio à África (1950-1965). A ênfase política decidiu que o contato com a África e que o estudo sobre ela deveria ser baseado no apoio aos movimentos de independência nacional. Compreender a África (1966-1976). Algumas instituições traduziram um grande número de obras na "Revolução Cultural" para melhorar a compreensão da África. Estudar a África (1977-). A reforma e a abertura levaram a comunidade acadêmica a se familiarizar com a África e a iniciar pesquisas preliminares. O desenvolvimento das relações entre a China e a África promoveu uma pesquisa geral sobre o continente (Li, A. 2005). Este artigo tenta explorar melhor os estudos africanos da China, que estão divididos em cinco partes, por exemplo, um histórico das relações entre a China e a África, uma breve ilustração das realizações de quatro gerações (especialmente dos jovens), a participação e contribuição dos estudiosos chineses na academia internacional; o desenvolvimento de instituições de pesquisa e uma análise da nova tendência dos estudos africanos na China.
Exploring the causes of flow attenuation at a beaver dam sequence.
Authors: Graham Hugh , Puttock Alan , Elliott Mark , Anderson Karen , Brazier Richard
Published: February 2022

Beavers influence hydrology by constructing woody dams. Using a before
after control impact experimental design, we quantified the effects of a
beaver dam sequence on the flow regime of a stream in SW England.
Building upon our previous research (Puttock et al., 2021), we consider
the mechanisms that underpin flow attenuation in beaver wetlands.
Rainfall-driven hydrological events were extracted between 2009 and
2020, for the impacted (n=612) and control (n=634) catchments, capturing
events seven years before and three years after beaver occupancy, at the
impacted site. General additive models were used to describe average
hydrograph geometry across all events. After beaver occupancy, Lag times
increased by 55.9% and declined by 17.5% in impacted and control
catchments, respectively. Flow duration curve analysis showed a larger
reduction in frequency of high flows, following beaver dam construction,
with declines of Q5 exceedance levels of 33% and 15% for impact and
control catchments, respectively. Using event total rainfall to predict
peak flow, five generalised linear models were fitted to test the
hypothesis that beaver dams attenuate flow, to a greater degree, with
larger storm magnitude. The best performing model showed we can have
high confidence that beaver dams attenuated peak flows, with increasing
magnitude, up to between 0.5-2.5 m s
for the 94 percentile of event
total rainfall; but we cannot confidently detect attenuation beyond the
97 percentile. Increasing flow attenuation, with
event magnitude, is attributed to transient floodplain storage in low
gradient/profile floodplain valleys. These findings support the
assertion that beaver dams restore attenuated flows. However, with
long-term datasets of extreme hydrological events lacking, it is
challenging to predict the effect of beaver dams during extreme events
with high precision. Beaver dams will have spatially variable impacts on
hydrological processes, requiring further investigation to quantify
responses to dams across differing landscapes and scales.

Ongoing neurovascular dysfunction contributes to type 2 diabetes mellitus (T2DM)-induced cognitive deficits. However, it is not known whether early post onset of T2DM interventions may reduce evolving neurovascular dysfunction and thereby lead to diminution of T2DM-induced cognitive deficits. Using multiple MRI metrics, we evaluated neurovascular changes in T2DM rats treated with exosomes derived from cerebral endothelial cells (CEC-Exos). Two months after induction of T2DM in middle-aged male rats by administration of streptozotocin nicotinamide, rats were randomly treated with CEC-Exos twice weekly or saline for 4 consecutive weeks (n = 10/group). MRI measurements were performed at the end of the treatment, which included cerebral blood flow (CBF), contrast-enhanced T1-weighted imaging, and relaxation time constants T1 and T2. MRI analysis showed that compared with controls, the CEC-Exo–treated T2DM rats exhibited significant elevation of T2 and CBF in white matter and significant augmentation of T1 and reduction of blood-brain barrier permeability in gray matter. In the hippocampus, CEC-Exo treatment significantly increased T1 and CBF. Furthermore, CEC-Exo treatment significantly reduced T2DM-induced cognitive deficits measured by the Morris water maze and odor recognition tests. Collectively, our corresponding MRI data demonstrate that treatment of T2DM rats with CEC-Exos robustly reduced neurovascular dysfunction in gray and white matter and the hippocampus.

The paper gives the analysis of the ship power plant its elements: a shaft line and deadwood bearings. The deadwood bearings are said to serve as supports for the ship shaft line. The operating conditions, the effect of loads and the occurrence of possible defects that reduce the life of deadwood bearings and the shaft line are described. The actual operation life of ships without repair depends on the technical condition of the deadwood unit and on the size of clearance between the propeller shaft and deadwood bearings which increases because of wear of the bearings. Structural and technological ways of increasing the reliability of deadwood bearings are described. It is stated that the resource loss of deadwood bearings is caused by the irreversible physical processes occurring on the surface and inside the bearings at the structural level under continuous cyclic stresses, which results in the extreme condition and wear unacceptable for further operation. There are considered the methods of improving the structures of the deadwood unit, as well as new solutions for the design or repair of ship deadwood bearings. There is proposed a new design of a deadwood bearing based on the requirements and rules of regulatory documents. A sketch and a picture of the proposed deadwood bearing are presented, which is a metal housing with segments made of two materials: ZX-100K (Zedex) and rubber. The proposed design of the deadwood bearing will increase the reliability of the ship deadwood device, eliminate non-working sections of segments and increase the support area of the propeller shaft on the bushings. It has been inferred that there is a possibility to reduce the contact static and dynamic specific loads and amortize the shock loads.

Authors: Lebedev Anatoly Ivanovich , Radaev Anatoly Vyacheslavovich
Published: February 2022

The negative impact of greenhouse gases and emissions of pollutants into the atmosphere force international organizations to take measures to reduce them. The International Maritime Organization (IMO) has worked out the strategy, whose provisions are aimed at reducing harmful emissions from ships into the atmosphere to zero. Achieving this goal is directly related to improving the energy efficiency of marine electric power systems, as the main elements generating, distributing and converting different types of energy. The concept of vessels with electric propulsion is becoming the most promising option for the implementation of “green energy” on ships. There has been considered the current state in solving technical problems to achieve zero emissions through the use of marine unified electric power systems with a DC distribution bus, the use of energy storage devices, supercapacitors. There have been illustrated the single-line diagrams of the electric power system of ships: with an autonomous propeller electric unit, with general DC distribution buses. The dependences of the efficiency of a synchronous generator MSK103-4 type on the frequency of the output voltage for load capacity of 20, 80, 140, 200 kW are given. The frequency fluctuations of the output voltage of a gas-diesel generator at 100% load have been analyzed. The main directions for improving power efficiency are outlined. It has been inferred that using modern technologies and materials is necessary to improve the energy efficiency of the electric power systems of ships and reduce emissions of harmful substances into the atmosphere.

The article focuses on modernization of a small model tank in Astrakhan State Technical University, which was used for comprehensive testing of outboard motors and analyzing the exhaust gases of outboard motors for harmful emissions. Modernization was undertaken to expand the types of experiments carried out with outboard motors based on a previously obtained utility model patent RU 196596 U1, 06.03.2020. The small experimental pool was equipped with technical means, such as a device (pipe outlet) for redirecting the water flow from the outboard motor propeller and measuring instruments for determining the level of noise, vibration, temperature, etc. For further testing, it was necessary to evaluate the amount of heat discharged into the water by exhaust gases from the deadwood of the outboard motor, by friction developed by the propeller in the water, by heating during operation of the bevel hypoid gear in the gearbox of the outboard motor, by using various types of lubricating oils. All these caused the need to equip the small experimental pool with thermal insulation to save heat. Due to the special requirements for the thermal insulation of the small experimental pool, namely, a small thickness of the coating, neutrality when interacting with combustible materials and lubricants there was used a heat-insulating paint produced by NPP Termalcom, LLC, Astratek Metal brand. To measure the specific parameters, in particular, noise of the gas exhaust system of an outboard motor, there arose a problem to conduct the experiments in the tank with an open lid, which could result in splashing water during the propeller rotation. A detailed description of technical solutions, designs and principles of action to eliminate the identified shortcomings in a small experimental pool is given.

The article highlights an important scientific and technical problem: increasing the operation efficiency of the diesel generator power plants. One of the possible solutions of the problem is developing the diesel generators that operate in a variable speed mode with shared loads on the power plant. Introducing such diesel power plants into practice in recent decades has become possible due to the necessary converting semiconductor equipment, as well as a significant increase in prices for hydrocarbon fuels and objectively formulated requirements to improve the environmental performance of technical complexes. There is presented a comparative analysis of the energy efficiency of two power plants: with classic diesel generators and with a variable speed diesel generator. It has been proposed to compare the energy efficiency of the power plants by calculating the specific and absolute fuel consumption. The method of determining parameters of fuel consumption is considered. The method is based on using a multi-parameter characteristic of a diesel engine and the values of the efficiency ratios of the elements of the power equipment of plants. The results of calculating the specific fuel consumption of the power plants when changing the load power subject to the operating mode of the generators are presented. The results confirm the energy efficiency of the power plant with a variable speed diesel generator. Efficiency is increased due to saving the hydrocarbon fuels. The maximal savings correspond to the power plant operation under the load 20% less than the nominal.

O artigo explora a temática de empreendedorismo social e como correlaciona ao modus vivendi das mulheres artesãs de Barbacena -MG que informalmente integram as feiras livres de artesanato do município, tal qual os significados que atribuem a sua prática de comercialização que resulta em sua inclusão/exclusão social. Para tal, a revisão bibliográfica e a aplicação de 12 questionários semiestruturados tornaram-se o alicerce deste ensaio. A análise, ancorada nas temáticas de Empreendedorismo e Empreendedorismo Social permitiu mapear aspectos polissêmicos das representações das mulheres no que diz respeito a sua posição neste nicho de mercado, notadamente percebido na literatura como instrumento de evasão do precariado. O estudo conclui que as protagonistas atribuem múltiplos significados a sua atuação neste contexto como o de que seu produto, antes de assumir valor financeiro, recebe questões subjetivas como o de realização pessoal e status frente ao grupo que participa e a sociedade que integra.

The purpose of the study is to contribute knowledge about how teaching in preschool can be understood in relation to how teaching is described by preschool teachers. The following research questions were posed: How do preschool teachers describe teaching and its meaning in preschool? and What didactic questions appear in preschool teachers’ descriptions of teaching in preschool? The empirical data consist of reflective texts that were analysed through content analysis with the help of Bernstein’s concepts: classification and framing, and visible and invisible pedagogy. The results show that the preschool teachers in the study perceived the introduction of the concept of teaching in preschool as an opportunity, which allowed them to become more aware of their actions in different learning situations. That the preschool teachers described teaching taking place through play and in everyday situations based on children's interests and needs hints at an organization with invisible pedagogy, weak classification and weak framing. Strong classification and strong framing, on the other hand, became manifest when the preschool teachers described that they plan what they do with the children and use materials, organize children’s groups and design environments to promote children’s learning.  Furthermore, the preschool teachers focused mainly on the didactic questions of how and why, while the what-question received less attention.
Den kroppsliga läsningen

This paper illuminates what fiction reading means inside and outside of Swedish schools. It also argues for the need to formulate this endeavour as both an epistemological project and a phenomenological one.  At the core of this paper lies a troubling state of affairs—that reading is declining—and a wish to trace the origins of this decline to find available means for remedy. To be able to grasp what fiction reading means in a phenomenological sense, the paper first embarks on a critical discussion of the reader and the text, which is followed by a methodological and theoretical section fully devoted to the effort of describing reading as such through Michel Henry’s concept of flesh. Armed with a phenomenological understanding of the significance of reading, the paper then places fiction reading within the context of Swedish education. The phenomenological analysis finds that in education, when reading fails to be preciselyreading (pathetic-esthetic reading), it is instead often transformed into something other (objectified reading or instrumental reading) than what it sets out to be. The paper uses a literary example to concretize its findings.
HOUSE OF BLACK SOLDIER FLIES PETERNAKAN DAN GALERI EKOSISTEM LALAT TENTARA HITAM

The Bantar Gebang Integrated Waste Disposal Site (Bantar Gebang Landfill) is the largest landfill in Asia. This unique ecosystem is born from millions of garbage which include mountains of inorganic and organic waste, thousands of scavengers, and millions of flies. However, the ecosystem in this landfill has not worked well, the components in the ecosystem still work independently and do not work in mutualism way. The program is present with the aim of maximizing the existing ecosystem in this landfill, by making the components as one unit. Such as the Black Soldier flies breeding program which is made from organic waste, a waste workshop for the scavengers, and an information gallery about flies and garbage for the outside people. Processing organic waste naturally (using Black Soldier flies), make this program is very environmentally and ecologically friendly. Design methods such as sustainability and biomimicry are used to produce projects that care about the environment, and target the psychological level of the people. By doing so, the project is expected to be able to help overcome the problem of organic waste in the Bantar Gebang Landfill, as well as open up public knowledge about waste management. Keywords: Bantar Gebang Landfill; disposal; flies, scavengers; waste.AbstrakTempat Pembuangan Sampah Terpadu (TPST) Bantar Gebang merupakan TPST terbesar se-Asia. Ekosistem yang unik lahir dari jutaan sampah yang meliputi gunungan sampah organik anorganik, ribuan pemulung, serta jutaan lalat. Akan tetapi, ekosistem di TPST ini belum bekerja dengan baik, antar komponen dalam ekosistem masih bekerja sendiri-sendiri dan tidak bekerja secara mutualisme. Program hadir dalam tujuan memaksimalkan ekosistem yang ada di TPST ini, dengan menjadikan antar komponen sebagai satu kesatuan. Seperti program peternakan lalat BSF yang berbahan dasar sampah organik, workshop sampah bagi para pemulung, dan galeri informasi mengenai lalat dan sampah bagi masyarakat luar. Mengolah sampah organik secara alami (menggunakan lalat BSF), maka program ini menjadi sangat ramah lingkungan dan ekologis. Metode perancangan seperti keberlanjutan dan biomimikri dipakai untuk menghasilkan proyek yang peduli terhadap lingkungan, serta menargetkan pada tingkat psikologis masyarakat. Dengan begitu, proyek diharapkan dapat membantu mengatasi masalah sampah organik di TPST Bantar Gebang, serta membuka wawasan masyarakat luas tentang pengolahan sampah.
