Energy and Economic Balance between Manure Stored and Used as a Substrate for Biogas Production

The aim of the study is to draw attention to the fact that reducing methane and nitrous oxide emissions as a result of traditional manure storage for several months in a pile is not only a non-ecological solution, but also unprofitable. A solution that combines both aspects—environmental and financial—is the use of manure as a substrate for a biogas plant, but immediately—directly after its removal from the dairy barn. As part of the case study, the energy and economic balance of a model farm with dairy farming for the scenario without biogas plant and with a biogas plant using manure as the main substrate in methane fermentation processes was also performed. Research data on the average emission of ammonia and nitrous oxide from 1 Mg of stored manure as well as the results of laboratory tests on the yield of biogas from dairy cows manure were obtained on the basis of samples taken from the farm being a case study. The use of a biogas installation would allow the emission of carbon dioxide equivalent to be reduced by up to 100 Mg per year. In addition, it has been shown that the estimated payback period for biogas installations is less than 5 years, and with the current trend of increasing energy prices, it may be even shorter—up to 4 years.

The Post-COVID-19 Future: State Capability in Ensuring Shared Prosperity

The coronavirus (COVID-19) pandemic has caused profound upheavals in national communities, from humanitarian disasters to unprecedented economic downturns. All the consequences of COVID-19 have made it necessary to understand the reasons for state inefficiency and its traditional functions of ensuring economic balance and financial stability in the period before COVID-19. In fact, inefficiency is a fundamental problem of modern socioeconomic systems. Only a violation of societal integrity can explain why economic isolation and social distancing managed to instantly destroy economic structures, cause a loss in confidence in governments by citizens and increase the potential for protest against the extraordinary actions of nation-states in the fight against COVID-19. At the end of 2020, there was universal agreement about a fundamentally uncertain post-COVID-19 reality. Many progressive specialists have expressed the opinion that the degree of future socioeconomic progress directly depends on the abilities of policymakers to prioritise societal integrity in solving economic problems and achieving the goal of shared prosperity in the future

The Enforcement of MUI Fatwa Number 1 of 2003 concerning Copyright for Merchants Selling Pirated VCD and DVD in Manado City

This article aims to determine the enforcement of the MUI Fatwa Number 1 of 2003 concerning Copyrights for Muslim merchants selling pirated VCDs and DVDs in Market 45, Manado City. A qualitative method with observation, interview, and documentation techniques was used to analyze the data. Of the six Muslim traders interviewed, the results showed that the MUI fatwa enforcement was ineffective due to the lack of socialization and evaluation of merchants. Also, the merchants did not stop selling pirated products because they lacked religious understanding and awareness and lived below the poverty line. At the same time, the authors' economic rights become a barrier to the public in accessing the product because it is valued beyond the ability of consumers. This study suggests that the MUI ought to pay attention to the economic balance between the authors' economic rights and the public, such as merchants.

THE PREEMINENCE OF CUSTOMARY LAW IN ARAB SOCIETIES AN ANTHROPOLOGY STUDY IN RURAL AREAS

The prevalence of customary law within Arab societies, and in particular in the area of ​​water sharing and the organization of agro-pastoral lands has created a kind of conflict between customary legality and the positive law of the modern state, this the latter having become incapable of establishing its laws on the rural areas in which the tribes settle, and which have codified standards and have become familiar with modern laws enacted by the state.In order to preserve the social and economic balance in the Arab countries, the authorities in power were forced to promulgate laws and decrees in accordance with the customs and traditions of their peoples, in particular those related to agro-pastoral activity. Therefore, it can be said that the aim of the modern state is to place custom in a legal form respected by social groups.

Functional Regions as Bases for Provinces in Slovenia

Socio-economically based functional regions, which are partially self-contained economic areas, are often more suitable for various structural analyses, implementation of state and regional policies, development of state administration, planning and monitoring of spatial development, identification of spatial disparities and other analyses of socio-economic relations than the traditional historically and geographically based administrative regions. This article therefore examines the assumption that functional regions are a suitable basis for the formation of territorial provinces in Slovenia. We have modelled the functional regions of Slovenia according to the established and internationally accepted method CURDS and compared them with the current proposals for provinces and established statistical regions in Slovenia. The results show a very strong functional contiguity and a good economic balance of eight provinces and a very good population balance of the provinces with two special status urban municipalities.

The arbitrage In Securities Market Model And Some There Properties

The applications of functional analysis in economics began worked out since the by presenting theoretical studies related to the development and balance of financial markets by building mathematical models with linear topological space , describing and defining the economic balance of the stock market in mathematical formulas and terms , and then using the theorems of linear topological spaces such as Han's theorems . Banach , separation theorems , open function theorem ,closed statement theorem and so on to create the necessary and sufficient condition to make the market model achieve viability , achieve no arbitrage , and not recognize No free Lunches

A Step Change in Wild Boar Management in Tuscany Region, Central Italy

In this chapter, reducing the high-density populations of wild boars in an Italian’s Tuscany region is addressed as a measure of controlling crop damage and road accidents. The issue is usually tackled from a technical and rarely sociological point of view, making the proposed and implemented solutions less effective. The results presented in these chapter highlight the importance of awareness of the social context when the technical choices are applied. The management of ungulates creates economic interests that oppose changes that shift the economic balance, even when the actions taken are for the benefit of the entire community’. In the previous decades, the wild boar populations have increased considerably in Italy in the Tuscany region. As a consequence of this phenomenon, damage to crops and road accidents has increased. In 2016, the Tuscany region enacted a law to change the management of ungulates by promoting individualism in unsustainable harvest rate areas, allowing shooting wild boar with stalking and selling the meat and maintaining a corporate approach in sustainable harvest rate areas. In three years of enforcing the law, damage to crops and road accidents have decreased significantly and meet supply chain has started. On the other hand, a strong reaction against this Law by wild boar drive hunters emerged. The region is, consequently, faced with an emblematic case where political intervention in future is inevitable in order to mediate between long-term results and short-term consensus.

Psycho-Socio-Juridic Review Of Lockdown And Work From Home Policies On Psychological Symptoms In Productive Groups And Strategic Solutions Of National Economy

Covid-19 pandemic has a significant impact on all strategic aspects of human life. The influential aspects are the health, economic and socio-cultural. The Covid-19 pandemic creates a dilemma for the Government to find the best way to benefit from various sectors efficiently. One of them is the implementation of lockdown and work from home to reduce the spread of Covid-19, but this has an impact on the emergence of various psychological disorders and the balance of the economic balance which tends to be negative. The focus of this research is to reveal the impact of the Covid-19 pandemic and lockdown and Work From Home policies on psychological symptoms and to find the best alternative solutions in terms of the economic sector. This research consists of 2 main parts, namely survey research and research that examines the problems based on sociology with qualitative methods with the type of normative juridical research. The results of this study reveal that during the Covid-19 pandemic period caused a 39.1% incidence of insomnia, 12.1% incidence of depression, and 26.3% incidence of anxiety from various levels. Still, there was no strong relationship and correlation between existing policies such as Work From Home, income, layoffs, spiritual, psychological symptoms. A literature review reveals the most effective way to bridge these three aspects (health, economy, and psychology) is by applying the form of shifting or taking turns by dividing into a minimum of 2 teams, namely a minimum of 14 days of work and a minimum of 14 days for independent isolation at home.

How Much Is the Abandonment of Forest Management in Private Forests Worth? A Case of Poland

The provision of forest ecosystem services (such as biodiversity, water and soil protection, and recreation) is often associated with a reduction in timber harvesting. In the case of private forests, such a situation requires institutional solutions that allow the economic balance of forest management to be maintained. The aim of the study was to find out the average value of monetary compensation private forest owners would expect in case of timber harvesting restrictions. The study was conducted with a random sample of 1003 forest landowners. The average value of expected compensation ranged from PLN 2300/year/ha (which corresponds to the price of about 12 m3 of wood in Poland) under the condition of no restrictions on timber harvesting but the need to apply indicated of forest management methods, to PLN 4900/year/ha in the model assuming a total ban on harvesting. In general, higher compensation was expected by farmers who stated that they sold timber and those whose agricultural area was larger than the average in Poland. When harvesting restrictions are low, the expected compensation is influenced by the age and gender of the respondent, or the number of people in the household.
