We have viewed a business in the south of the Great Plain Region from an economic point of view in 2004-2005. The main activity there is pear growing and storage. Four varieties of different time of ripening and storing are grown there. We have measured all the relevant activities, worked out a local normative and prepared a detailed technology. The economic evaluation was based on this data. Activities, like disinfection, pre-storage disinfection and selection, in-storing and out-storing, classification after storage, packaging, as well as loading trucks, were monitored by variety. Storage loss was determined and widely varied according to varieties, length of storage and time of out-storing. Different varieties resulted in different quality classes after storage. Price depended on the quality classes. Economic evaluation was carried out when all the relevant costs and revenues were known. Fixed and variable costs of storage were determined, break-even point was calculate and the market position of the product was evaluated.

The purpose of this study is to analyze the production of copper nanoparticles (Cu NPs) on an industrial scale in an engineering perspective and economic evaluation perspective. Energy is needed because of various energy related applications. Evaluation of Cu nanoparticle production in an engineering perspective is carried out from the selection of processes that are adapted to industrial scale, calculation of mass balance, to the adjustment of commercially available equipment. Evaluation of production from an economic point of view is done by calculating economic parameters: Gross Profit Margin, Internal Return Rate, Payback Period, Cumulative Net Present Value, Profitability Index, and Break Even Point. Briefly from the production process, we use Copper acetate hydrate (CuAc2.2H2O) (as a source of Cu), Tween 80 (polyoxyethylene-(80)-sorbitan monooleate) and ethylene glycol (as a reducing agent). The engineering viewpoint shows this process is capable of producing Cu nanoparticles which can be used as conductive nanoionic. Economic evaluation determines the process is beneficial, discussing with positive values ​​all economic parameters. However, for some variations this process is not profitable, so economic evaluation is needed.

Copper nanoparticles are the most frequently used materials in the field of nanoscience because of their electrical, optical, biomedical, antifungal, and antibacterial properties. The synthesis of copper nanoparticles with biological methods is known to be environmentally friendly, inexpensive, simple, and capable of producing better nanoparticles than other methods. This study aims to determine the feasibility of an industrial project to manufacture Cu nanoparticles through a biosynthetic method using Citrus medica Linn. extract and evaluate it from an engineering and economic point of view. Some of the parameters used for economic evaluation are Payback Period (PBP), Break Even Point (BEP), and Cumulative Net Present Value (CNPV). The analysis is supported using data taken from online shopping websites. The results showed that the number of Cu nanoparticles that could be produced in one year was 24,000 kg. The total initial capital cost is 272,640.00 USD and the profit is 698,655.90 USD/year. PBP occurred in the 3rd year with the CNPV/TIC value reaching 3.746% in the 9th year. Based on the economic evaluation, the project is concluded to be feasible to run with the anticipated tax and percentage of sales. The results of this study are expected to provide an overview of the economic evaluation of industrial-scale Cu nanoparticles production by biosynthetic method using Citrus medica Linn. extract.

For soilless vegetable production of the Southern Great Plain region in Hungary, there is enough water available, however, the origin and chemical composition of it are decisive from the point of view of practicability. The ground water is everywhere accessible, although its sodium and chloride content is almost always significant, moreover, human pollution may occur (e.g. nitrates and phosphates). A further unfavourable moment is the seasonal variation observed within the area of the same community. The abundant supply of water in the Quaternary strata are located in more than half of the cases within the upper 50 m region. As by the expected changes of the climate, a strategic increment of the importance of subsurface waters is anticipated. Their composition is relatively stable, and the prognoses are reliable for the same settlement. Salt content of the majority of water resources bearing hydrocarbonates is low, however, streaming of the subsurface waters tend to increase their sodium content and to diminish their calcium and magnesium, whereas the pH increases (mainly by ion-exchange). Water quality is decisive not only because of the interaction with the plants but also from the point of view of the distribution of water. Some micro-elements, mainly iron and secondarily manganese may cause problems, therefore, irrigation water ought to be prepared carefully. Production technology should be completed by a technical equipment using aeration for the elimination of ironinfluence of yields on rate of return of investment; (3) the role of increasing of added value content of products. Importance of the utilisation of alternative channels of distribution and the formation of producers' cooperatives are underlined, being based on calculation of return of investment.

Abstract This paper presents an economical assessment of the benefits of introducing 5G technologies into pilot use cases pertaining to the railroad transportation and energy sectors. For each of the pilots, undergone by EFACEC Engenharia e Sistemas and EFACEC Energia, respectively, under the scope of the H2020 5Growth project, evaluates the expenditure and benefits expected from introducing 5G capabilities over their on-going operations. This evaluation is expressed regarding the Portugal case, and are also scaled to assess the European-wide case. The main objective of the study summarized in this paper is to understand if solutions proposed by the H2020 5Growth project, and 5G as a whole, are also advantageous from an economic point of view. The results of the techno-economic analysis reported in this paper show, on a European scale, millions of euros saved by the different stakeholders involved in the deployment of 5G solutions.

It is a widely accepted practice in the European Union to break down countries into regions according to their stage of development, their cultural and economic characteristics. The basis of this methodology is the EU-conform MOTS system, which distinguishes territorial units on five levels. Besides the MOTS system, Hungary uses another system, too, which is the basis of our public administration, and whose roots go back to the times of King Saint Stephen: the county system. In Hungary, developmental decisions are taken by a county’s general assembly; at the same time, from an economic point of view the characteristics and competitive advantages of a county can be defined more precisely than those of a region. Szabolcs-Szatmár-Bereg County and Hajdu-Bihaur County may be described with completely different characteristics, albeit both of them are part of the North Great Plain Region. On a county level economically important and justified developmental areas may be mapped more precisely. Hajdu-Bihar County is the 4th most populous county in Hungary. With 80.2% of the population living in cities, the county is significantly urbanized. 2010 statistics show that the birth rate per 1,000 people in the county is practically the same as the birth rate of the country and that of the North Great Plain Region. Following the trends in developed countries, mothers now tend to give birth in an older age. Almost half (44.5%) of the children in Hajdu-Bihar County are born after their mother’s 30th birthday. The general health condition of the population of Hajdu-Bihar County can be described with various indicators. In terms of medical and hospital care no difference can be observed between regional and national data, the county’s health care does not straggle behind. In sum, with the health care system of the county, estimated life expectancy of men is higher than the regional average, and in case of women it is higher than both the regional and national average, according to the given year’s mortality. Children’s ratio among the county’s population is 15.9%, which is more than 1% over the national average. The ratio is higher in case of girls and boys alike. The income of the county’s population depends not only on labour income but also on social benefits. According to the analysis, the proportion of old-age pensioners and those receiving pension-like allowances within the whole population is somewhat lower in the county than the national average. The number of children receiving child-welfare and daytime care is prominent in the county. The number of families and children receiving child-care allowance has not changed significantly in recent years. All important elements of social benefits have increased in the last decade. The quality of life of the county’s population is largely affected by the presence (or absence) of basic infrastructure in their environment. Research conducted at the settlements of the county shows that currently the greater part of the population has access to basic public utility services which form part of everyday services. Although they affect the general quality of life, the network of roads and passenger traffic have their real significance in terms of economic development. The county’s modern, paved road-system had already been built earlier. Roads and pavements in inner-city areas have been paved up to 70%. The technical condition of roads and pavements can seriously impede the population’s mobility and it may hinder the development of certain settlements and districts.

In this contribution we focus on the role of experts in the assessment of tort damages from an economic point of view. We distinguish two different aspects.First, we examine the role which economists might play in assessing damages in tort cases. This approach focuses on the insights that Law and Economics provides regarding the correct assessment of damages. We pay specific attention to two problematic forms of losses where economic insights may play an important role: pure economic loss and personal injury damage (both loss of income and compensation for immaterial losses due to fatal and non-fatal accidents).Second, we investigate from a Law and Economics point of view the role of experts in general (not only economists) in the assessment of damages. We discuss i.a. the question why experts may be involved in the assessment of damages, the potential problems (and the possible solutions) when using experts, and differences between party appointed experts and court appointed experts.It turns out that the economic analysis can provide a different, insightful viewpoint in some respects, such as the fact that market based mechanisms may help to provide incentives to party appointed experts to provide an accurate and objective damage assessment.

The high freshwater consumption requirements in shrimp biorefinery approaches represents one of the major drawbacks of implementing these technologies within the shrimp processing industry. This also affects the costs associated with the plant operation, and consequently, the overall economic performance of the project. The application of mass integration tools such as water pinch analysis can reduce frewshwater consumption by up to 80%, contributing to shrimp biorefinery sustainability. In this work, the economic evaluation and the techno-economic sensitivity analysis for a mass integrated approach for shrimp biorefinery were performed to determine the economic feasibility of the project when located in the North-Colombia region and to identify the critical techno-economic variables affecting the profitability of the process. The integrated approach designed to process 4113.09 tons of fresh shrimp in Colombia reaches a return on investment (%ROI) at 65.88% and a net present value (NPV) at 10.40 MM USD. The process supports decreases of up to 28% in capacity of production and increases of 12% and 11% in the cost of raw materials and variable operating costs without incurring losses, respectively. These findings suggest that the proposed design of the water recycling network coupled to a shrimp biorefinery approach is attractive from an economic point of view.

This paper investigates the role technology can play in fostering good business practices that would deter economic corruption and extortion in developing countries. This paper first provides a problem statement with a brief description of corruption in form of bribery and extortion based on Foreign Corrupt Practices Act (FCPA) and its provisions. Second, we propose a definition of bribery and extortion. Our definitions indicate that, contrary to what is often claimed, many of the kinds of payments forbidden by the Foreign Corrupt Practices Act are not instances of bribery, but rather extortion. Third, we present an economic analysis of bribery and extortion and explain why they are thought to be undesirable practices from an economic point of view. Fourth, we present two case studies to support the use of technology to mitigate and facilitate business in developing countries that should improve economic and business practices.

For optimal farm management, it is very important to research potential opportunities of raising its rental ability. These opportunities lie as by side of selling income as of its costs. It causes a necesity of constant cost control and of looking for new methods of reducing these costs. The aim of study was the assessment of economic viability of family dairy farms .The economic efficiency of these farms was analysed according to scale of production. Basic indicators and measures of the economic efficiency of production, such as net agricultural income, gross margin, production costs, parity income and break-even point were calculated. The paper presents the analyze of disproportion income between small and large farms. The executed analysis showed that from economic point of view the optimal dairy farms maintains about 60 cows.
