Mercury emissions from cement plants has attracted the attention of the world, the United States and the European Union and other developed countries have already made strictly limitations of mercury emission from cement plants,China has also been developed to limitation of mercury emission from cement plants. Mercury of cement plants comes mainly from coal and raw materials.,and mercury from flue gas can be removed by removal equipment, so you can use mercury control technology to remove mercury in flue gas. Depending on the different size and raw materials, of the plants, and mercury emissions under different conditions is not the same, so there is no mature mercury removal technology can be applied directly.1 Overview

The twenty-first century is being touted as the Asian century. With its stable economy, good governance, education system, and above all the abundant natural resources, will Australia to take its place in the global economy by becoming more entrepreneurial and accelerating its rate of growth, or will it get infected with the so-called Dutch disease? It has been successful in managing trade ties with fast-developing economies like China and India as well as developed countries like the United States. It has participated in the growth of China by providing iron ore and coal. Because it is a low-risk country, it has enabled inflow of large foreign capital investments. A lot will depend on its capability and willingness to invest the capital available in entrepreneurial ventures, its ability to capture the full value chain of natural resources, and to export the finished products instead of raw materials, while building a robust manufacturing sector.

The healthcare industry is a large and fast-growing segment of the corporate world, especially in developed countries. In the face of growing competition, healthcare companies inevitably resort to mergers and acquisitions (M&As) in order to accelerate their development. The objective of this study is to identify the creation of additional value for M&A deal participants in the healthcare industry in the United States and the European Union in 2008-2017. In this paper, we propose the following thesis statement: can healthcare companies expect excess returns from M&A deals? On average, M&A deals in the healthcare industry in developed countries create positive abnormal returns for acquiring companies and are efficient; a positive, significant impact on abnormal returns was found in the deal value of M&A deals, a negative significant impact was observed for deals conducted with the shares payment method and for acquiring companies with a larger number of employees.

One of the factors for the development of civil society in democratically developed countries is an effective, wellfunctioning institution for providing administrative electronic services. Despite the intensity and wide scope of research covering various aspects of providing electronic administrative services to the population, many issues in this area remain quite debatable, as well as understudied, which conditioned the relevance of the study. The study is aimed at investigating the specific features of implementing electronic administrative services in the practice of countries with the most developed e-government mechanisms. In the study of the problem, a set of general scientific and special methods of cognition was used, in particular, the leading methods were: dialectical, comparative legal, analysis, synthesis, interpretation. The study analysed criteria for evaluating electronic administrative services in the leading countries of the European Union and the United States. The study examines the basic electronic administrative services for citizens in online mode provided in the countries of the European Commonwealth. The study examines the global experience of implementing electronic administrative services in such countries as: USA; France; Great Britain; Germany; Estonia and Sweden. The author’s approach to defining the concept of electronic administrative services is formulated, based on a personal interpretation of this concept from the standpoint of general theoretical analysis. It is concluded that one of the best ways to encourage the provision of administrative services in electronic form in the countries of the European Union is to standardise their provision – the development of clear organisational and technical-technological rules and requirements, and their main position is that the provision of services through electronic means of communication should complement, and not replace other communication channels

This chapter identifies four clusters of nations based on state of development, in order to highlight significant qualitative differences that may call for different law and policies. The first cluster comprises the least developed sub-Saharan African countries with the most resource-challenged competition authorities, such as Benin and Togo. The second cluster compromises nations that have advanced economically to a perceptibly higher level. The third cluster is a “group” of one—South Africa. With all of its challenges, the South African competition regime is as close to a gold standard as there is in sub-Saharan Africa. Finally, for comparison, the fourth cluster comprises the developed countries, led in particular by the European Union and the United States. These nations have open economies, fairly robust markets, good infrastructure, and good institutions. The chapter proceeds to identify, from the point of view of each of the clusters, the most fitting competition framework nationally and globally. The chapter proposes how the divergences can be brought into sympathy.

The paper is devoted to an analysis of the development of agrarian farms in Visegrad Group (V4) countries, primarily in terms of results and the most important production inputs of production factors and their efficiency in the period from 2004 to 2013 based on the EU Farm Accountancy Data Network (FADN). The results of the analysis show that if farms in the V4 countries want to achieve the same performance as developed countries, they must invest more in purchasing intensification factors and adjust the structure of assets production specification. It will be necessary to stop the reduction in the numbers of livestock and to strive for growth in gross farm income, mainly through the processing of agricultural raw materials.

This paper deals with the impact of the most important factors of the total production costs in bioethanol production. The most influential factors are: total investment costs, price of raw materials (price of biomass, enzymes, yeast), and energy costs. Taking into account these factors, a procedure for estimation total production costs was establish. In order to gain insight into the relationship of production and selling price of bioethanol, price of bioethanol for some countries of the European Union and the United States are given.

The need for an income is cited by several studies as a primary motive for both formal and informal business start-up activities found in emerging countries. Conversely, entrepreneurs from developed countries enjoying more favorable economic conditions (such as the United States, Canada, or the European Union) are mainly motivated by intrinsic motives. Given the extant literature, it appeared important to determine which motivators were at play in larger Mexican urban centers, where economic conditions seemed to have become similar to those of Canada and the United States. No significant differences were observed between the motives of female as compared to male entrepreneurs from urban Mexico because a majority went into business primarily for economic reasons rather than for intrinsic motives. Knowing that Mexican entrepreneurs are mostly motivated by economic goals should help local governments in designing policies aimed at fostering and facilitating entrepreneurship.

The heavy metals including Pb, Cd, Cr, As and Mn emission characteristics of coal-fired power plant boilers, industrial boilers, lead and zinc smelters, cement kilns, and steel industries were studied in this paper. The removing effects of heavy metals by pollution control technology were analyzed. ICP-AES method was used to measure the contents of heavy metals in solid samples. In addition, M-29, the U.S. EPA isokinetic sampling method was used to sample heavy metals in the flue gas, and the sampled heavy metals were tested by ICP-AES-hydride generator system. For coal-fired boilers, heavy metal contents in descending order were Mn, Pb and Cd in the tested coal. The heavy metals’ emission concentrations of coal-fired industrial boilers were much higher than the heavy metals’ emission concentrations of power plants. For the lead and zinc smelters, Pb and its compounds in flue gas after cleaning can meet the emission standards. The heavy metal contents in the cement raw materials in descending order were Pb, Cr and Cd. For the sintering mixture, the heavy metal contents in descending order were Pb, Cr and Cd as well. The removal effects of heavy metals by existing pollutant control technologies in the various typical industries were also tested and analyzed in the paper. The research did in the paper made a scientific basis for controlling heavy metal emissions from typical industries.

In view of the new Brazilian agribusiness scenario, this article aims to analyze, through a literature review, the challenges and perspectives for Brazilian agribusiness. The methodology adopted was a bi-biographical research. The theoretical considerations pointed out in this study demonstrate the Brazilian agribusiness is an activity that has great representativeness within the economy of the country. It has been shown that one of the challenges is to ensure greater participation in trade liberalization, with a greater counterpart of developed countries, such as the United States and the European Union, in order to gain greater access to international agroindustrial markets. Greater efficiency of public infrastructure services, especially the precariousness of road transport modes, are challenges for this sector. These studies conclude that there is a need to formulate public as well as private policies in order to make greater use of the subregion's potential in the subregion and to build sustainable and sustainable development

The paper presents in a broad outline the main characteristics of the evolution of the Finnish high-tech industry and ICT sector within the context of general changes in industry and the national economy. In the last decades of the 20th century Finland dynamically developed a knowledge-based economy and became one of the leaders of the information society. A spectacular manifestation of this is the position of the country in global competitiveness rankings, where Finland has occupied a top position for several years, sometimes even being ahead of the United States. The so-called ‘Finnish model of information society’ is characterised, among others, by a significant growth in knowledge-intensive industries and a complex system of research and development support. However, all those changes were dependent on the previous development path of the country. The structure of Finnish industry was rather one-sided until the 1980s, when knowledge- and expertise-intensive production started to catch up with the level of manufacturing dominated by raw materials, capital and energy. For a long time, Finland specialised in the forest industry and in the processing of metals. A new sector that has developed during the past decades is electronics and, especially, the manufacturing of communication devices. Furthermore, the economy has changed more dramatically in Finland than in any other developed country over the same period of time. Industries have become technology-intensive and production is strongly characterised by specialisation. Finland has become the most specialised country in information and communication technology in the world, and this specialisation trend is continuing. The forest industry and other traditional industries rely more and more on the new technologies and state-of-the-art knowledge. In Finland, industrialisation started later than in other countries, but it was very rapid. Industrial production and exports grew faster than the rest of the economy in the 1990s, and the structure of exports diversified. Unlike other developed countries, Finland “re-industrialised” in the 1990s. The contribution of industry to the total volume of production and employment has been higher in Finland than in other advanced economies in the past couple of years.
