Capacitive proximity skin for non-contact liquid state measurement of robot grippers with different structures

Handling liquid-filled containers is a frequently encountered yet challenging task for robotics. In this paper, a novel capacitive proximity skin was developed to measure liquid levels before grasping, improving the performance of robotics in application areas like domestic service, manufacturing, healthcare, and food processing. This capacitive proximity skin features a flexible structure that is readily adaptable to a variety of grippers, and it seamlessly integrates with Robot Operating System (ROS)-based control systems. Experiments were performed to compare this proximity skin against non-flexible capacitive proximity sensors, focusing on detection frequency and working distance. The results showed that the capacitive proximity skin achieved data-lossless detection in 0.08 s (12.5 Hz) and contactless measurement of liquid level within 0.7 cm, making it highly suitable for grasping operations. This capacitive proximity skin offers as a versatile solution for robotic applications that involve unsealed liquid-filled containers, and it has the potential for application across a wide range of industries.

Gluing characteristics of Papua New Guinea timber species for various non-structural applications

Papua New Guinea (PNG) has abundant natural forest resources but there are many constraints which need to be addressed to support the development of competitive value-added wood industries. There is a need to develop knowledge and capacity in wood science and processing technologies which support successful domestic value-adding wood processing enterprises. A comprehensive testing program has been developed to assess the glue‐bond strength and performance of selected commercial PNG timber species in various climatic conditions to simulate service conditions in potential market destinations. Two criteria namely shear strength and wood failure have been used to determine if a species can meet the minimum requirements for either dry use or wet use applications. The performance of 24 different PNG commercial timber species has been assessed using a one-component cross-linking polyvinyl acetate emulsion adhesive. The bondability of the selected species has been carefully estimated considering the wood density and wood moisture content for the strength and durability in dry- and wet-use conditions. The testing results show that as the wood density as a wood property factor and moisture content as a service condition factor increase, high shear strength with high wood failure become more difficult to achieve consistently. The highest shear strength and wood failure results were achieved by softwood plantation species and low-density hardwood species. Based on the testing results, the selected species have been classified into bondability classes (bond very well, bond well, bond with difficulty, very difficult to bond).

Ecological and economic expediency of introducing modern membrane technologies of deep processing of milk whey

The article presents methodological and applied principles for justifying the feasibility of introducing modern membrane technologies of deep processing of milk whey into the practice of Ukrainian milk processing enterprises. It has been identified that the most common way of processing milk whey both in Ukraine and in global practice is its drying. As an alternative to the traditional technology of drying milk whey, it is proposed to introduce into the practice of Ukrainian milk processing enterprises an innovative technology of its deep processing, which includes the fractionation of whey proteins and the release of lactose derivatives, which is important for the use of processing products as innovative functional food products. The expediency of introducing modern membrane technologies of whey processing at domestic milk processing enterprises is substantiated, which allows rational use of raw milk resources, reducing the negative impact on the environment, and increasing the profitability of production. The results of calculations of the total ecological and economic effect are presented, which prove that the effect of the introduction of modern membrane technologies of deep processing of milk raw materials significantly exceeds the effect of using the traditional technology of drying milk whey, which is widely used in domestic milk processing enterprises. It was found that the ecological effect is manifested in the reduction of volumes of liquid industrial waste and fines for violations of environmental legislation and can be considered as an alternative to the construction of own treatment facilities. The economic effect is achieved by expanding the product range of exports and the offer on the world markets of high-margin dairy products for narrow target groups of consumers.

A design evaluation tool for older adults using domestic information processing appliances

Domestic information processing appliances include embedded digital technologies with which users interact. The designs of such appliances tend to be technology oriented and not well-suited to the needs of older adults. This is problematic because these appliances are essential in many activities of daily living and so affect the ability of people to live independently. This paper introduces a coding scheme for the analysis of users' interactions with such appliances and uses it to inform recommendations for the design of operational interfaces and associated instructional materials. The efficacy of the coding scheme as a design evaluation tool is illustrated by its application in a microwave oven case study. The coding scheme considers four aspects of users' interactions with this type of device: information processing activities, including the gathering and interpretation of information from the appliance, its user manual and cooking instructions from food packaging; interactions with the device's user interface; concurrent verbalisation supporting problem-solving; and impediments to the user's workflow.

How much wood do we use and how do we use it? Estimating Danish wood flows, circularity, and cascading using national material flow accounts

Understanding how much wood we use and how we use it has important implications for forest management, economic policy, and climate action. While individual wood streams are documented by various sources, a comprehensive, economy-wide mapping of wood use has been lacking in Denmark.Our study set out to produce a comprehensive national wood flow analysis for all wood products, to include harvest, import, export, and domestic flows through the economy, as well as to assess the level of circular and cascading wood resource use. We used the Physical Supply-Use Tables compiled by Statistics Denmark in combination with other sources to construct wood flows in m3 solid wood equivalent (SWE), enabling comparison throughout the processing chain with the standing natural resource.We estimated total Danish use of wood fibre in 2018 to be around 17.7 million m3 SWE, of which more than 15 million m3 was used for energy production. Most wood used in Denmark is imported, with a net import of more than 11 million m3 SWE. Apart from energy use the domestic wood processing, construction, and furniture industries are the largest users.By using mass balancing principles, we identified significant undocumented flows of wood from nature to the economy which are currently used for energy purposes, representing more than 1 million m3 SWE per year from 2015 to 2021, and we estimated the output of secondary wood products from the wood industry to be around 400,000 m3 SWE in 2018.According to Eurostat's Circular Material Use rate indicator, 8.4% of wood used is recycled and reused domestically, though with imported wood for energy excluded, the rate would be higher, around 17.8%. The overall cascading factor for wood in the Danish economy was calculated to 1.44, indicating that wood is used almost one and a half times before oxidation or final consumption.Ongoing monitoring of Danish wood flows would permit further analysis of any changes in patterns of use and reuse, and our estimates of wood flows could likely be improved with investigation of currently undocumented streams and country specific conversion factors.

Grand strategy for accelerating the development of the cocoa processing industry in Indonesia

This paper concerning about strategy development of downstream agroindustry of cocoa. As we have known, cocoa is one of the prime commodity export of Indonesia. Although Indonesia was producer of no 3rd in the world, but in the reality also still import of cocoa bean. Eighty percent of cocoa bean from Indonesia was exporting only 20% to fulfill requirement of domestic industry. Needed a strategy to accelerated of downstream industry of cocoa. This paper will present a strategy using the gap analysis methodology using SWOT Analysis. Improving the aspects of cultivation including post-harvest and increasing land production are driving forces for the cocoa industry. The application of SNI must be carried out immediately after the supporting facilities are fulfilled and applied in a disciplined manner, both for cocoa marketed domestically and for export. Provision of incentive schemes for farmers and domestic processing industries.

Cashew processing in Ghana – A case for infant industry support?

West Africa produces almost half of the world's cashew nuts. With the domestic cashew processing industry still in its infancy, however, most of it is exported as raw material and processed in India and Vietnam. In Ghana, this is provoking discussions about market interventions to support domestic processing. Since different price policies have diverging implications for farmers and processors, the choice of the policy instrument leads to conflicts of interest between the two groups. In this study, we analyse the short- and long-term economic impacts of enhancing cashew processing through (i.) a temporary export tax on raw cashew nuts, (ii.) a temporary subsidy to cashew processors, and (iii.)a temporary export tax on raw cashew nuts, with government revenues passed on to cashew growers. For this purpose, we develop a partial equilibrium model for the Ghanaian cashew market including the processing from raw cashew nuts to kernels. We find that in the short run, all price policies lead to a substantial increase in processing at the expense of net welfare. We argue, however, that the sector may experience productivity gains through learning by doing and thus, after price policies are phased out, stick to its increased level of output such that short-term welfare losses could be recouped. Therefore, temporarily introduced price policies could help the infant cashew processing industry to grow up, promote the development of the domestic cashew sector, and be welfare-enhancing in the long run. A subsidy to processors is the most appropriate option to achieve this.

The Paradox of Downstream Mining Industry Development in Indonesia: Analysis and Challenges

Development of downstream on the mining industry has been encouraged by the government of Indonesia these past years. With the increasing demand for nickel ore, the government focused on implementing downstream in this sector. Establishing an export ban and domestic processing requirement on nickel ore caused the EU to challenge Indonesia before the DSB WTO. In its report to the Panel, it was concluded that Indonesia had violated the provisions of GATT 1994. While it is understandable that Indonesia has absolute sovereignty over its natural resources, it is also bounded to international organisations and regulations, for it has expressed its consent. This paper aims to examine the analysis by the Panel on what caused Indonesia to decide as the losing party and how Indonesia would implement the development downstream in the middle of its sovereignty and obligations on an international level. Through a juridical normative method, it is concluded that Indonesia had failed to comply with the provisions of GATT 1994 that obliged it. It does not mean it has no sovereignty towards its natural resources, for it has agreed to be bound by the provisions. In order to exercise downstream development, it is recommended that Indonesia create national policies or regulations related to adhering to the provisions of the WTO. A cautious approach to governing the downstream may prevent potentially damaging disputes.

Forced labour risk is pervasive in the US land-based food supply

Social risk assessments and case studies of labour conditions in food production primarily focus on specific subpopulations, regions and commodities. To date, research has not systematically assessed labour conditions against international standards across diverse, complex food products. Here we combine data on production, trade, labour intensity and qualitative risk coding to quantitatively assess the risk of forced labour embedded in the US land-based food supply, building on our previous assessment of fruits and vegetables. We demonstrate that animal-based proteins, processed fruits and vegetables, and discretionary foods are major contributors to forced labour risk and that 62% of total forced labour risk stems from domestic production or processing. Our findings reveal the widespread risk of forced labour present in the US food supply and the necessity of collaborative action across all countries—high, middle and low income—to eliminate reliance on labour exploitation.

Фінансово-економічне стимулювання розвитку переробної промисловості на основі природно-ресурсного потенціалу регіонів у повоєнний період

Introduction. Financial and economic stimulation can be considered as one of the most effective ways to support the domestic processing industry as a whole and restore established or create new chains of generation of added value in the conditions of the legal regime of martial law. This actualizes the need to deepen the research of predictors and challenges of this process and the formation of approaches to the application of the most appropriate forms and tools of financial and economic stimulation, primarily in the regions of Western and Central Ukraine, which are currently actually a catalyst for the recovery of economic growth. Problem Statement. The sphere of financial and economic stimulation of the development of the processing industry through the prism of deepening the processing of natural resources in war and post-war conditions. The purpose is to determine the priority forms and directions of financial and economic stimulation of the development of the processing industry due to the in-depth processing of natural resources in Ukraine in the war and post-war periods based on the application of promising forms and tools of stimulation, using a natural resource and production potential of the western and central regions of Ukraine, which suffered the least economic losses as a result of Russian full-scale aggression. Methods. The methods of monographic analysis, comparison and analogies, correlation-regression, tabular and graphic analysis, and financial and economic synthesis were used. Results. The trends (both before the war and under the conditions of the legal regime of martial law) towards the growth of the role of the processing industry of the western and central regions, in particular in the context of the implementation of the Plan for the recovery Ukraine from the consequences of the war, have been established. Given the uncertainty of the pace of post-war reconstruction, it is advisable to carry out such regulation in the following directions: 1) improvement of the system of financial and economic stimulation formed before the war, taking into account the achieved adaptation progress of its forms and methods to the reform of decentralization in all its manifestations; 2) prioritization of strategically important spheres of processing, which have a significant potential for further development, capable of meeting the immediate needs of the security and defense forces; 3) integration of foreign financial and investment flows and innovative technologies into the national economic system for its extended recovery in accordance with the best global standards; 4) improvement of the state financial and credit system of support for business entities; 5) implementation of the principles of the concept of sustainable and comprehensive development and/or recovery. It has been proven that the stimulation of clustering processes in general and the formation of a new for Ukraine institute of agricultural and construction clusters in particular, the development of industrial and technological parks, primarily in the regions of Western and Central Ukraine, will contribute to the sustainable and comprehensive ontogenesis of the domestic processing industry. The successful implementation of these tasks requires effective coordination of relevant actions by the state and territorial communities, as well as an active position of medium and large businesses, as well as the creation of a favorable investment climate for attracting foreign investments. Conclusions. Prospective forms of ensuring the accelerated recovery of the processing industry from the consequences of armed aggression include industrial parks. When forming their network, it is important to take into account the natural resource potential and the traditional territorial production and economic specialization of the regions of our country. In particular, in the regions of Western and Central Ukraine, which have large areas of agricultural and forestry land, a significant number of small rivers, it is advisable to promote the creation of specialized industrial parks for the development of in-depth processing in the areas of food, light, woodworking, forest chemical industry, building materials industry, and also to develop a favorable environment for the development of renewable energy technologies (biogas, biodiesel, bioethanol, small hydropower plants, etc.).

Research on production technology of smoked-dried salted pork leg meat to ensure food hygiene and safety

Salted and smoked pork leg products (Ham) have become prevalent in the world for a long time. Although these foods have appeared in Vietnam for a few years, consumers warmly received them due to their tasty specificity. The quality of this product group is affected by several technological factors, including the composition of salty solution and additives, the technique of bringing meat, the heat treatment process (drying, smoking, steaming), and storage conditions. Therefore, the research of production technology to ensure food safety and hygiene are essential. Furthermore, level 2 orthogonal experimental matrix and optimization of technological factors have been applied for the best product quality. The study provides a perfect example of the production technology of bringing and drying meat products to ensure food hygiene and safety for consumers, contributing to promoting the domestic meat processing industry to develop in the direction of industrialization, safety, and integration.

MODERNIZATION OF PRODUCTION PROCESSES BY MILK PROCESSING ENTERPRISES OF UKRAINE AS A FACTOR IN INCREASING THE COMPETITIVENESS OF PRODUCTS

The article examines the relevance and substantiates the need for the introduction of the latest technologies and the modernization of existing production resources by domestic milk processing enterprises. The dynamics of the active enterprises of the milk processing industry of Ukraine over the last ten years were analyzed, and their structure for 2020 was also considered. For a generalized understanding of the state of development of the milk processing industry of Ukraine, the number of operating enterprises by region was studied and ranked. It was determined that the leaders of the milk processing industry are the following regions: Kyiv, Kharkiv, Lviv, Vinnytsia and Kyiv regions. As a result of the stable growth of the number of milk processing enterprises in Ukraine, the competition in the market of dairy products is also increasing, therefore business entities need to actively look for opportunities to increase the competitiveness of their products, and this is possible by introducing the latest and resource-saving technologies into their economic activity. A technical and economic substantiation of the application of the automatic system for washing the milk line of milking units UDM-100 "Bratslavchanka" and UDE-16 "Yalynka" was carried out. It is substantiated that in order to increase the quality of milk, production efficiency and resource saving (by reducing the consumption of air, hot water, energy and operating costs) it is advisable to use the invention, which increases the efficiency of the milking system washing system by using air and hydraulic injectors with automated control of mode parameters of their action depending on indicators of contamination of the milk-conducting equipment.

Scalar politics in transboundary fisheries management: The Western and Central Pacific Fisheries Commission as an eco-scalar fix for South Pacific albacore tuna management

Scholars and policymakers have debated the correct scales for managing and conserving ocean resources for decades. To address the conservation and management of highly migratory fish species, like tuna, countries have established regional fisheries management organisations (RFMOs) to regulate transboundary fisheries at the scale of oceanic regions. However, in the Western and Central Pacific Ocean region, countries have expanded their tuna management efforts to encompass multiple and overlapping intergovernmental institutions operating at regional and subregional scales. Scholars have argued that this proliferation of institutions across scales—including the development of the region’s RFMO, the Western and Central Pacific Fisheries Commission (WCPFC)—has strengthened transboundary tuna management. However, while scholars focus on the successes of scalar dynamics in the tropical purse seine fishery, less attention has been devoted to the smaller and less valuable southern longline fishery, where management progress has stalled. Management inaction at multiple scales has impacted the status of the fishery’s target stock, South Pacific albacore, and domestic fishing and processing industries in Pacific Island countries and territories. This article employs a scalar politics lens to consider why multi-scalar efforts to improve southern longline fishery management have produced no decisive change in management outcomes. Analysing over a decade of management debate and subregional institutional development, the article argues that the WCPFC has operated as an ‘eco-scalar fix’ in managing the southern longline fishery. Through a combination of ecological and political factors unique to the fishery, this eco-scalar fix has enabled distant water fishing countries to locate political authority with the WCPFC while shifting the responsibility for management reform onto the subregional efforts of Pacific Island countries. This case complicates and contributes to debates concerning scale in transboundary fisheries management by concluding that the effects of scalar politics on management outcomes are uneven and the product of asymmetrical, interest-driven dynamics among countries seeking to advance their interests in industrial fisheries.

Modern realities and trends in food security of the Republic of Kazakhstan

The problems of food self-sufficiency are global in the modern world. Quality food largely determines the health of the nation. In the context of global climate change, increasing food demand, depletion and scarcity of resources, pandemic, military conflicts, special attention should be paid to the aspects of sustainable economic growth. The article reflects approaches to the definition of the concept of "food independence" in the world, as well as its various components. The goal is to study food issue, to study the indicators used to assess the global food security index (hereinafter referred to as GFSI). Methods – set of statistical, theoretical and analytical methods was used. Results – GFSI for 2022 is analyzed, Food Security Plan of the Republic of Kazakhstan for 2022-2024 and prospects for its development are considered. Conclusions – the authors state that the republic is rising in the world ranking; this indicates the effective implementation of programs aimed to supply the country's citizens with affordable and high-quality products. Kazakhstan fully provides itself with such goods as flour, milk, meat, cereals, salt, sunflower oil. However, satisfaction of the needs of the population in canned food, sausage, fish and sugar has not yet reached the required level of domestic production. Despite the best government support measures, the share of processed goods is still low. Therefore, it is necessary to develop domestic agriculture and processing of agricultural products at a qualitatively new level. State support for agricultural producers should take into account regional aspects (natural and climatic conditions, territorial distribution of lands and level of their degradation). It is necessary to provide assistance through digitalization (installation and maintenance of appropriate systems; increase Internet coverage areas, etc.).

INNOVATIVE ENTREPRENEURSHIP AS A FACTOR OF THE DEVELOPMENT OF THE PROCESSING INDUSTRY

The development of modern innovative entrepreneurship is one of the main ways of Ukraine’s sustainable development. Innovations are a powerful tool that enhances its economic security and ensures competitiveness. Innovation is a driving factor in the development of both individual sectors of the economy and the entire economic system of any country. That is why the authors consider innovation as a factor in increasing the level of Ukraine’s competitiveness in the world market. The authors carried out a general assessment of the level of innovation in the domestic economy. The monitoring of the basic indicators of innovation was carried out based on a comparison of the positions of Ukraine and other European countries in world rankings, which characterizes innovative development. It was found that in 2021 Ukraine took 58th place in the Bloomberg Innovation Development Index. In 2022, it entered such rankings as the Global Innovation Index and the Networked Readiness Index, where it ranked 57 and 50, respectively. Ukraine lags far behind the advanced countries of Europe in the process of forming an innovative type of economic system. The authors found that the basis for ensuring the sustainable development of our state is the activity of processing industry enterprises. In recent years, the domestic processing industry brings about 10-11% of the total GDP. The authors note that it is advisable to define innovativeness as an extremely important and effective tool for improving the efficiency of the functioning of the business of the processing sector of the industry. The modern Ukrainian economy is characterized by the predominance of manufacturing enterprises with low-level technologies among the enterprises of the processing industry. For the period 2018-2020, the share of the number of innovatively active enterprises of the domestic processing industry was only 13.1%. However, despite the influence of various negative development factors, experts tend to believe that the development of innovative entrepreneurship in the processing industry, which will be based on the introduction of the latest innovative solutions in the production process, is important for the post-war recovery of Ukraine and strengthening its position in the world market.

Effects of domestic cooking on the bioactive compounds of pohpohan leaves (Pilea trinervia L)

This study aimed to analyze the influence of domestic cooking methods on the total phenolic content (TPC), antioxidant activity, and bioactive compounds of pohpohan leaves. This is the first study to examine the effect of domestic processing on the bioactive compounds of pohpohan leaves. The cooking methods included boiling for 5 and 15 mins at 100°C, boiling for 5 and 15 mins at 70°C, steaming for 5 and 15 mins, and heating by microwave for 1 and 3 mins. The TPC was determined by using the Folin-Ciocalteu method, while the antioxidant activity analysis was conducted by 2,2-diphenyl-1- picrylhydrazyl assay. Moreover, the bioactive components (caffeic and ferulic acids) were analyzed by a reversed phase-ultra high-performance liquid chromatography. The results showed that domestic cooking significantly decreased the TPC and antioxidant activity of pohpohan leaves, with the lowest changes recorded for steaming and microwave heating. The highest TPC was observed in raw leaves extract, measuring about 84.43±3.43 mg GAE/100 g wet basis, followed by microwave heating, steaming, and boiling, respectively. The highest antioxidant activity was measured in raw leaves extract, followed by steaming and boiling. Additionally, microwave heating significantly enhanced the antioxidant activity of pohpohan leaves and preserved the ferulic and caffeic acid content. In summary, domestic processing methods have different effects on the preservation of TPC, antioxidant activity, and bioactive compounds and these results are implied in the functional properties of pohpohan leaves.

INVESTIGATION OF THE EFFECT OF MECHANOCHEMICAL ACTIVATION IN A SHOCK-REFLECTIVE MILL ON THE CRYSTAL STRUCTURE OF NATURAL GRAPHITE

In this work, studies the changes in the crystal structure of the natural graphite of the Taiga deposit were carried out in the process of spheroidization. The spheroidization process consisted in giving the flat graphite particles of a quasi-spherical shape due to mechanochemical activation in a centrifugal mill of the shock-reflective principle of action. Spherical graphite obtained by mechanochemical spheroidization is currently the dominant anode material of lithium-ion batteries on the market. Currently, the problem of obtaining electrode materials based on domestic raw materials and using domestic processing technologies is becoming urgent. In the course of the work, it was found that the graphite under study consists of two graphite substructures with a greater and lesser degree of graphitation. During mechanochemical activation of graphite in a centrifugal mill of the shock-reflective principle, a significant change in the crystal structure of both substructures occurs, consisting in a decrease in the size of the crystallites, a decrease in the degree of graphitation and the formation of a rhombohedral phase. It is also noted that the changes in the structure are wave-like, and the less graphitized substructure is subject to stronger fluctuations. In the process of spheroidization, a decrease in the proportion of a more graphitized substructure and its transition to a less graphitized one was noted. In addition, it was found that the spheroidization process is accompanied by a decrease in the degree of texture of the crystal structure, expressed by a decrease in the ratio of the integral intensities of reflexes (002) and (110) corresponding to the crystallographic planes "c" and "a", respectively. An increase in the intensity of the impact from 55 m/s to 85 m/s makes it possible to intensify the ongoing processes, while no significant deterioration in the degree of graphitation was noted.

Phosphorus in waste sources in Southern Vietnam: potential for recovery

The potential for phosphorus (P) recovery from various sources in Southern Vietnam has been assessed in this study. Five types of waste were studied, namely sediment from catfish pond, manure from cattle and pig farming, and also sludge from domestic and rubber-latex processing wastewater-treatment plants. The study identifies P-reserve and assesses factors related to P recovery from waste sources such as distribution, collection, transportation conditions, and composition of wastes. P-reserve from catfish farming is estimated about 17.7 kt yr-1 while reserve from pig farming is the highest, about 21.7 kt yr-1. Total P-reserves from studied wastes are estimated about 50 kt yr-1, equivalent to 37% of Vietnam’s imported nutrient P quantity in 2019. Generated sludge from rubber-latex processing wastewater-treatment plants has the highest potential and favorable properties for P recovery. It turns out to be feasible to collect and recover P from this waste source under Vietnam’s current conditions.
