IMPROVING THE DURABILITY OF CULTIVATOR BLADES USING ONE-SIDED GAS-FLAME SURFACING

In agar production one of the most common technological operations is cutting of soil or plants. It makes up at least 70% of the total volume of mechanized works. The purpose of this study is to help maintain the agrotechnological parameters of the cultivator's blade by coating the blade with powder wear-resistant coatings using the one-sided gas-flame surfacing technology. The technology of strengthening the cultivator blade using one-sided gas-flame surfacing is applied. As a result, were defined: powder granulation on the thickness of the applied layer; modes and parameters of the one-sided gas-flame surfacing during the formation of composite material coating. Foreign experience of the last decades shows that with the development of gasometric spraying methods it is possible to atomize various materials such as polymers, carbides, metals. These coatings withstand the impact of high thermal loads, shock-abrasive and chemically active environments. Comparison of application methods mentioned above shows that the quality of coatings expressed in the parameters: adhesions, porosity, oxidation levels remain at approximately the same level. However, a comparative analysis of foreign practice has shown that the method of gas-flame surfacing is more technological, more productivity, and the specific costs of the coating are reduced.

Podkarpackie Voivodeship is one of the regions of Poland in which the number of agritourism entities is very high. Therefore tourism plays a significant role in its development strategy. The aim of the paper is to identify the current state of agritourism and the changes that have occurred in the region in the years 2000–2016. Specific objectives are to determine the distribution of agritourism farms and their offer, together with a comprehensive analysis of the environmental and socio-economic factors, as well as the impact of the Slovak-Ukrainian border. The report was developed on the statistical materials from the Polish Central Statistical Office, Podkarpackie Agricultural Advisory Centre in Boguchwała and data collected from municipalities and district offices that is published on their websites, as well as through interviews with 100 owners of agritourism farms in the Podkarpackie Voivodeship. The research has shown, on the one hand, the decline in the number of farms in the region and, on the other hand, the increase in the diversity of the tourist offer of these entities. Distribution of agritourism farms is closely linked to the attractiveness of natural environment and quality of secondary tourism resources. Traditional agritourism has not yet fully used its countryside, as well as cross-border advantages of its location.

The aim of this study is to determine the existence of a characteristic personality profile of family carers of people with dementia. The correct knowledge and use of psychological variables which affect the carer, helps to promote appropriate actions to mitigate the impact of care and improve the carer’s quality of life and likewise the one of the person cared for. The study population consists of 69 family carers of people with dementia, members of various associations and care centers. The results allow us to identify a characteristic personality profile for these carers and it reveals a specific psychological working in this sample, although we cannot directly relate it with the tasks of caring for people with this disease, this profile gives us very relevant information to pay more attention to the needs of this group. Moreover, the analysis of personality styles depends on the sex of the family carer, showing, once again, that the woman is in a situation of most vulnerability.

The Impact

This study investigates the impact of pre-treatment options on the performances of soil columns simulating soil aquifer treatment (SAT). For this purpose a conventional activated sludge (CAS) process, a membrane bioreactor (MBR) and vertical flow reed beds were used as single units or in combination before SAT. The influent and effluent from each treatment train were monitored over three successive 6-month periods, corresponding to changes in the operational conditions of the MBR and CAS units from 6 days' sludge retention time (SRT) to 12 and 20 days. All the columns acted as efficient polishing steps for solids and bacteria. The column receiving effluent from the CAS system running at 6 days' SRT also presented high total nitrogen and total phosphorus removals, but this column was also associated with the lowest infiltration rates over that period. While the quality of the effluent from the column following the CAS process increased over 18 months of operation, the effluent quality of the columns receiving MBR effluent degraded. No correlations were found between variations in SRT of the MBR and CAS processes and the columns' performances. Overall, all columns, except the one receiving CAS effluent, underwent a reduction in infiltration rate over 18 months.

El objetivo de la presente investigación, cuyo corte metodológico es mixto, ha sido conocer el impacto que ejercen los influencers deportivos en un grupo poblacional de 404 adolescentes andaluces encuestados y 10 entrevistados cuya edad abarca desde los 16 hasta los 20 años. Atendiendo a los principales hallazgos, se demuestra que estos influencers contribuyen de manera positiva a aumentar el grado de motivación y adherencia por la actividad física. De forma sintética, el estudio establece una disociación entre la modalidad deportiva que se practica y el género del adolescente. Con esta afirmación queda expresado que ambos géneros tienen tendencia a seguir a influencers de su mismo género. Además, no se ha podido determinar que los hombres compren más dispositivos electrónicos que las mujeres. Sin embargo, un aspecto significativo a nivel estadístico es que el género masculino presenta más tendencia por compartir los datos en redes sociales y que los adolescentes que han comprado un dispositivo han intentado, en la mayor medida posible, que la marca se asemeje al que promociona su influencer. Concluimos que la labor que ejercen estos personajes públicos sobre sus seguidores es eficaz y directa, pues son capaces de incidir significativamente y mejorar la calidad de vida de todo aquel que los secunden. Abstract. The main of this research, whose methodological approach is mixed, has been to determine (otra opción: was to determine) the impact of sports influencers have on a population group of 404 Andalusian adolescents surveyed and 10 interviewees whose age ranges from 16 to 20 years. According to the main findings, it is shown that these influencers contribute positively to increasing the degree of motivation and adherence to physical activity. In summary, the study establishes a dissociation between the type of sport practiced and the gender of the adolescent. This statement shows that both genders tend to follow influencers of the same gender. In addition, it could not be determined that men buy more electronic devices than women. However, a statistically significant aspect is that males are more likely to share data on social media and that adolescents who have bought a device have tried, as much as possible, to have the brand resemble the one promoted by their influencer. Finally, it is concluded that the work of these public figures over their followers is effective and direct, as they are able to have a significant impact and improve the quality of life of all those who support them.

The Impact

The article offeres an approach to including ecological factor in the Human Development Index (HDI). HDI is aimed at reflecting the quality of life of population, which is defined along with other important characteristics and state of environment. However, there is still no ecological living conditions of population in the formalized representation of HDI. Two directions of constructing ecologically adjusted HDI are developed: introducing ecological index to HDR, and using ecologically adjusted GDP/GRP in income index. Ecological index reflecting the state of environment in the places of residence and recreation of population is constructed on the basis of indicators of the number of air/water samples exceeding the ambient standards, as a percentage of the total number of examined samples. This indicator is presented in the annex to the statistical handbook «Environment Protection in Russia» for all regions. It is offered to modify the index of income in HDI by subtraction of the economic damage caused by pollution from income, as this part of income does not go to growth of the population welfare, but only compensates for the damage. For implementation of this approach there is no official statistics, and in the study was used the database accumulated by the author over many years of ecological-economic research. As a result, there was calculated ecologically adjusted HDI for all 85 regions in comparison with the traditional HDI. In 14 regions with the best ecological situation the HDI value grew, in the others it decreased. Some of the regions formerly leading by the HDI value lost their positions. Comparing the impact on HDI of ecological index on the one hand, and of modifications of income index on the other, showed an incomparably greater role of the introduction of ecological index.

<p>Until recently, new technologies introduced into irrigated agriculture were mainly aimed at developing one or several related control actions. However, the needs of society to increase the volume and improve the quality of agricultural products have led to significant qualitative changes in irrigated agriculture. The various robotic systems used for this have proven their effectiveness in the mechanization and automation of the irrigation process, as well as in the application of chemical fertilizers and chemical protection of agricultural crops from diseases and pests. This resulted in higher yields while lowering production costs.Nowadays, biotechnologies currently being developed and being introduced into irrigated agriculture, as well as systems for controlling and monitoring environmental impacts, are aimed at solving problems related to further increasing the efficiency of the use of natural resources, while minimizing the risks of negative impact on components and services of the environment.This is largely due to the impact of the rapid development of IC and sensor technologies aimed at creating production management systems based on the cyber-physical systems (CPS) paradigm. For this, there are using a holistic vision of the structure and cybernetic methods of management, artificial intelligence technologies, as well as digital platforms for integrating information flows between sub-subsystems of management, control, monitoring and decision support.In this context, the main difference between developed agricultural CPSs from the existing industrial agricultural systems focused on current economic efficiency lies in the plane of making agricultural production sustainable in the long term based on a balance between economic efficiency and the quality of natural resources used and services of the environment. From this point of view, irrigated agriculture focuses on the efficient use of natural resources, which are water, soil and air, as well as renewable and non-renewable (fossil) energy. At the same time, weather are considered as the impact of the external environment providing an irreplaceable source of water, heat and energy resources but with stochastic characteristics that are difficult to formalize. In connection with this diversity, a CPSs are built taking into account a complex compromise that takes into account many aspects of the negative impact of intensive agricultural production technologies on the qualitative and quantitative characteristics of these resources, not only in the place of their use, but also on the external environment beyond these limits. In this regard, water resources are one of the most important factors necessary, on the one hand, to impart long-term sustainability to irrigated agriculture, and on the one hand, as a factor that can lead in the near future to a significant decrease in fertility, as well as to a negative impact on the environmental services of the surrounding area. This contribution discusses some points of the development of an agricultural irrigation CPS&#8217; subsystem aimed to monitor the soil moisture content at the root zone of the soil cover at the scale of irrigated agricultural crops and their relationship with industrial sprinkling technologies.Acknowledgments: The reported study was funded by RFBR, project number 19-29-05261 mk</p>

The Impact

The paper considers an integrated approach for constructing models for predicting the perioperative parameters of laparoscopic kidney resections, which include the duration of the operation, the time of thermal ischemia, and the glomerular filtration rate 24 hours after the operation. The approach is based on the principle of expanding the feature space, extracted from the analysis of the surgeon's "learning curve" data when mastering laparoscopic kidney resections. The aim of this work is to predict the main perioperative parameters that have the most significant impact on the surgical tactics of treatment at the stage of planning surgery. New methods have been developed for identifying significant parameters that take into account the complexity of the operation and the qualifications of the surgeon based on his “learning curve”. The parameters to be distinguished include: “complexity of the operation” based on nephrometric indices (RENAL, PADUA and C-index); the average value of the predicted perioperative parameters of surgical interventions depending on the complexity; slope and standard error based on the regression line of predicted perioperative parameters. Models were developed for predicting the perioperative parameters of laparoscopic organ-preserving kidney interventions using modern approaches based on machine learning, which are based on the algorithms “decision trees”, “multilayer perceptron”, “Naïve Bayes”, “logistic regression”. A comparative analysis of the quality of the developed models was carried out, as a result of which the best result was obtained using the “logistic regression” algorithm. The F-measure was used as a metric. A comparative analysis of the developed models was carried out to assess the impact on the final quality of the new selected features. For the predicted parameter “time of thermal ischemia” the increase was from 9.68% to 16.68%; for the predicted parameter “duration of surgery” the increase was from 2.76% to 4.08%. At the same time, for the predicted parameter “GFR in 24 hours” there was no significant increase, and for the “multilayer perceptron” algorithm it turned out to be negative. The obtained forecasting models can be used in applied software solutions that act as decision support systems in determining the surgical tactics of treating patients with localized formations of the renal parenchyma. Such software solutions can be implemented as a web service or as a separate program.
