In the article, the authors discuss the necessity of the mulching layer in organic farming technology and provide substantiation of parameters of a machine for packing and chopping of green manure on soil surface. The purpose of the research is to develop a machine for chopping of green manure on soil surface, which increases productivity and provides proper quality of the technological process. Developing such a machine is a quite urgent problem at present when the use of stubble remains and green manure in aggregate with other factors provides opportunities for increasing the fertility of the soil. When carrying out the research the authors used theoretical and experimental methods based on applying the fundamentals of the agricultural mechanics, the theory of agricultural machines and methods of measurement regulated by normative documents. In the article, the authors present the results of the research that substantiate a constructive-technological scheme of the machine for chopping of green manure and mulching of soil surface. Also the authors present the substantiation of the parameters of a roller with chopping elements that is the main working tool. Besides the authors present the results of experimental research which confirm the theoretical research on parameters of the roller. Based on the conducted research the authors concluded that the developed machine provides quality chopping of green manure and mulching of soil surface in organic farming technology.

Rose cultivation requires many inputs for satisfactory production, making the process expensive. Nowadays, alternative practices have been used for sustainable crop production. Green manure is an agricultural practice that aims to maintain or improve soil fertility, increasing its yielding capacity. The objective of this research was to evaluate the effect of green manure with legumes on the yield and quality of ‘Vegas’ roses. Grafted rose seedlings were cultivated in open field for 30 months. Legumes used as green manure and planted intercropped with rose bushes were forage peanut (Arachis pintoi) and jack bean (Canavalia ensiformis). Pigeon pea (Cajanus cajan) was grown in a separate area, cut, macerated, and applied in the rows between rose bushes every 3 months. Plants of control group received no green manure, only mineral fertilizer and cattle manure, as in all other treatments. The experimental design was randomized block with four treatments (three green manure species plus the control) and seven replications. The highest yield and quality of flower stems in ‘Vegas’ occurred with addition of pigeon pea on the soil surface or chemically treated (control). Forage peanut and jack bean are not suitable for intercropping with ‘Vegas’ rose bushes due to possible nutrient and water competition.

While there is growing recognition of the positive role played by organic farming in the reduction of the negative externalities due to conventional agriculture, there is uncertainty about the effect of the latter on the economic performance of the farms. In this scenario, the present paper aims at investigating the effect of organic farming on technical efficiency in Italian olive farms. A cross-section dataset was analyzed through the stochastic frontier function, where the adoption of organic farming was explicitly modeled. Then, to obtain an unbiased estimate of the impact of organic farming on technical efficiency, a propensity score matching method was implemented. The findings reveal that organic farming increases technical efficiency in Italian olive farms by approximately 10%. The highest impact of organic farming is observed in small farms. As for the propensity to become organic, we found that the production and the direct sales of a higher quality of gross marketable output, as well as the intensity of labor and machines, increase the probability to adopt organic farming. Conversely, farm localization, the availability of family labor, and financial capital discourage conversion to the organic farming system.

Over the years, rural areas have faced a number of problems and difficulties, such as an increase in the average age of the population, desertification, loss of employment and the abandonment of rural and agricultural activities, which have led to the emergence of new initiatives aimed at revitalizing these territories from a social, economic and environmental perspective, such as the successful Bio-districts or Eco-regions (e.g., Bio-district of Cilento). Understanding and establishing a proper framework for each territory based on agroecology and participatory methodologies is still a challenge. In this sense, based on the analysis of two European examples—Cilento, Italy and São Pedro do Sul, Portugal—we described each of the building processes and defined a set of drivers that might constitute guiding principles to serve as a basis for the creation of Bio-districts or Eco-regions. The drivers’ matrix identified was discussed in three focus groups carried out in Portugal in 2020. Such drivers included a technical and environmental component (the quality of the environment and landscape, the food system and the implementation of organic farming and agroecological practices), a social and economic component (valorization of the farmers, products and territories and a set of different stakeholders—farmers, consumers, schools, tourism entities and restaurants, local authorities) and a political component (the governance model). Most participants agreed that the recognition of a Bio-district or Eco-region should be informal, bottom-up, with farmers as the main pillar, with a fair and representative participation, namely family farmers.

AbstractThe medical practice of declawing has received much political debate over the past few years. Yet, empirical and theoretical research on how this practice is maintained and the ethical positions of those who actually participate in this work is lacking. Drawing from 9 months of ethnographic fieldwork in a feline-specific veterinary hospital and open-ended interviews with veterinarians and staff, this study examines veterinary staff members' attitudes toward, and strategies for, dealing with the medical practice of declawing. Specifically, findings show that a number of staff felt uncomfortable with their participation in onychectomy (declawing) and relied heavily on organizational support structures to cope both with these feelings and the moral ambiguity about the practice. Relying on these structures, the veterinarians and their staff are able simultaneously to define felines as subjects worthy of respect for their quality of life, protect their own self-identity as people who work toward the best interest of animals, and paradoxically support action toward felines that they find morally objectionable.

Compared to traditional EDM processing, UEDM (Ultrasonic Vibration Assisted EDM) have a great improvement in optimizing discharge environment. In this study, ultrasonic vibration is attached to the electrode. According to the relative positional relationship between the movement path of the electrode tip and the discharge gap, four working states of UEDM are defined. The four working states are the path within the discharge gap, the path in contact with the edge of the discharge gap, part of the electrode end path outside the discharge gap, and the path in contact with the workpiece, respectively. States are analyzed from the effective discharge energy and discharge frequency. A mathematical model for effective discharge energy and surface roughness is established for two conventional working states. The correctness of the theoretical research is verified by experiments. As the experiment results shown, the influence of ultrasonic amplitude on the energy of UEDM is primary, while frequency is secondary. A working state with better discharge stability and higher discharge energy when the electrode end path is in contact with the edge of the discharge gap. In the first three conventional machining states, the surface quality of the workpiece increases with the increase of ultrasonic amplitude and frequency. The study can provide scientific guidance for parameter matching of UEDM.

This article discusses the problem of choosing the correct and effective organizational structure of enterprise management for its correct functioning. The existing types of organizational structures of enterprise management, which are used in practice today, are analyzed, and their positive, negative sides and the type of enterprises for which they can be used are revealed. Along with this, this article discusses and describes methods for choosing an organizational structure for an enterprise. Also, during the study, internal and external factors were identified that affect the choice of an organizational structure. Based on the analysis, a methodology for choosing the most effective type of organizational structure for enterprises was drawn up. The question of choosing an organizational structure is acute for every manager at the very beginning of the operation of an enterprise, because the quality of performance of functions, both of individual divisions and of the entire enterprise as a whole, directly depends on this. Among many types of organizational structures in this study, the types of organizational structures that are most adaptable to changes in external and internal factors are identified. This study provides methods and tools for selecting the appropriate organizational structure for any enterprise. At the moment, some methods, be it goal structuring or computer modeling, are not widely used, which in turn makes it difficult to choose an effective organizational structure for enterprise management. The choice of an effective organizational structure is an extremely urgent problem today for every entrepreneur, who is interested in the stable economic activity of his or her enterprise.

This paper presents a theoretical research on electronic resources provided for mathematics education in primary school including online education, which has become ubiquitous as a result of the COVID-19 pandemic. Various aspects and forms of application of e-resources in mathematics education are explored in the literature, but the issue of their quality is less studied. E-resources potential to dynamically illustrate the mathematical learning content is defined as their main advantage, but this potential could be realized only in compliance with the principles of multimedia, as well as the requirements for accessibility, ergonomics and visual design. Therefore, in this study the parameters for the quality of e-resources for mathematics education in primary school are derived and specific criteria and requirements for their quality are proposed. Thus, in addition to providing a basis for future research, this paper could serve to primary teachers as a guide for measuring the quality of e-resources that they select or create for online mathematics education.

ISO organization (https://www.iso.org) in early 90s defined an industry standard for the communication protocol among electronic devices of different manufacturers of agricultural machines. After that, all of the market actors recognised that this technology would be very important for agricultural electronics. The appearance of ISOBUS products in the market was in the mid-2000s. ISOBUS description could be found in ISO-11783 (https://www.iso.org). Through the standards and the related technical background, the production processes and the operations could be followed and monitored by the extensive Data Management. Farmers' and users legitimate needs and developing goal is to elaborate a decision support systems that follow-up the utilisation of the machines and ensure the quality of operations. For this purpose, it is essential to determine which technical, economical, technological parameters detection, measurement, transmission, processing, and evaluation becomes necessary. In our work, we reviewed which mechanical characteristic, settings are monitored within the ISOBUS system by the major machine manufacturers. We developed the system of parameters and derived features that provide effective farm-, and land-management in case of attached equipment for spreading of input materials, plant protection and tillage implements.
