As the country's rapid economic growth, the contradiction between people and the environment are more and more prominent, and the way which can make economic growth at the cost of the environment is not scientific. This article introduces that there is much industrial surplus heat in the dynamic wind pump house of QRRS (Qiqihar Railway Rolling Stock Co., Ltd) which is directly discharged without any treating, which produces unnecessary energy wasting and economic losses. But now there is the solution—making use of surplus heat generated from air compressor cooling water in dynamic wind pump house to heat bathing water (the water from molding line, furnace transformer and tap-water) with water source heat pump, which can achieve the goal of Energy Conservation & Emission Reduction.

Electricity is a key infrastructural input in the modern economy which increasingly aids in achieving a higher standard of living and rapid economic growth. Its inadequacy or, absence paralyses the functioning of all sectors and leads to economic losses. There is close association between electricity consumption and economic growth. The present study attempts to make the economic analysis of Gulbarga Electricity Supply Company (GESCOM). The study is based on primary data. The data were collected from selected talukas, villages and the sample domestic consumers’ in the study area. Total 350 domestic consumers’ were selected randomly by adopting a multi stage stratified random sampling for each village. The data analysed with the help of suitable statistical techniques like simple percentage, average, ratio etc. The study finds considerable awareness among the consumers and has they understand the importance of electricity and created the sense of proud about its functioning. The empirical results, further reveal that the practical problems of power cut in the regions. KEYWORDS: Electricity, Domestic Consumers, Billing, Complaint and GESCOM.

During the 2000s Chile achieved rapid economic growth and improved most labour market indicators: the unemployment rate fell; the mix of employment by occupational position and sector improved; the educational level of the employed population, the percentage of registered workers, and labour earnings increased; and all poverty and inequality indicators decreased. The economy suffered a recession during the international crisis of 2008, but recovered quickly. The chapter shows that some labour market indicators were negatively affected by the crisis. The unemployment rate was the only indicator that did not return to its pre-crisis level by the end of the period studied.

Vietnam has been remarkably successful in managing structural adjustment and macroeconomic reform. As a result, it has achieved very rapid economic growth during the present decade without, apparently, a substantial increase in inequality. All sectors of the economy have grown rapidly and yet there has been dramatic structural change. This growth and structural change, according to official data, have occurred despite a relatively low rate of investment. Our analysis suggests, however, that savings and investment have been understated, that actual output is higher than the national accounts data indicate and that growth is even faster than the official figures suggest. These results are a consequence of the nature and sequencing of the policy reforms that were introduced from the 1980s onwards.

Abstract Background Bluetongue (BT) is a vector-borne viral disease of ruminant and camelid species which is transmitted by Culicoides spp. The causative agent of BT is bluetongue virus (BTV) that belongs to genus Orbivirus of the family Reoviridae. The clinical disease is seen mainly in sheep but mostly sub-clinical infections of BT are seen in cattle, goats and camelids. The clinical reaction of camels to infection is usually not apparent. The disease is notifiable to the World Organization for Animal Health (OIE), causing great economic losses due to decreased trade and high mortality and morbidity rates associated with bluetongue outbreaks. The objective of this study was to investigate the seroprevalence of BTV in camels in Kassala State, Eastern Sudan and to identify the potential risk factors associated with the infection. A cross sectional study using a structured questionnaire survey was conducted during 2015–2016. A total of 210 serum samples were collected randomly from camels from 8 localities of Kassala State. The serum samples were screened for the presence of BTV specific immunoglobulin (IgG) antibodies using a competitive enzyme-linked immunosorbent assay (cELISA). Results Seropositivity to BTV IgG was detected in 165 of 210 camels’ sera accounting for a prevalence of 78.6%. Potential risk factors to BTV infection were associated with sex (OR = 0.061, p-value = 0.001) and seasonal river as water source for drinking (OR = 32.257, p-value = 0.0108). Conclusions Sex and seasonal river as water source for drinking were considered as potential risk factors for seropositivity to BTV in camels. The high prevalence of BTV in camels in Kassala State, Eastern Sudan, necessitates further epidemiological studies of BTV infection in camels and other ruminant species to better be able to control BT disease in this region.

AbstractThis study explores entrepreneurship research in Vietnam, a lower-middle-income country in Southeast Asia that has witnessed rapid economic growth since the 1990s but has nonetheless been absent in the relevant Western-centric literature. Using an exclusively developed software, the study presents a structured dataset on entrepreneurship research in Vietnam from 2008 to 2018, highlighting: low research output, low creativity level, inattention to entrepreneurship theories, and instead, a focus on practical business matters. The scholarship remains limited due to the detachment between the academic and entrepreneur communities. More important are the findings that Vietnamese research on entrepreneurship, still in its infancy, diverges significantly from those in developed and emerging economies in terms of their content and methods. These studies are contextualized to a large extent to reflect the concerns of a developing economy still burdened by the high financial and nonfinancial costs.

The Asia-Pacific countries achieved rapid economic growth with the flying-goose model in the 1980s, growth buttressed by export-oriented development strategies and the policy culture in these countries. While Japan and the other Asia-Pacific countries still have strong growth potential, many problems remain, including trade imbalances with the United States and the rise of protectionism there, the Asia-Pacific economies' vulnerability, and the need to consolidate the infrastructure for growth. It is imperative that Japan contribute to the development of the region by responding effectively to these issues and that it strengthen the international trading arrangements by promoting Asia-Pacific cooperation premised on openness. Given the region's great internal diversity, Asia-Pacific economic cooperation can well serve as a model for international economic coordination.

China’S Economy

The benefits deriving from rapid economic growth have chiefly accrued to capital returns. Consequently, the decline in the share of Chinese gross domestic product (GDP) accounted for by labour income has been most pronounced. To sustain growth, China will have to ensure robust consumption. Increasing the labour share in GDP and hence promoting domestic consumption will play a decisive role in rebalancing China’s economy.

This article explains why massive political corruption appears to be incompatible with economic growth in Russia but compatible with very rapid economic growth in China. The common assumption is that corruption is bad for economic performance. So how can we explain the puzzling contrast between Russia and China? Is Russia being more severely “punished” for its corruption than China? If so, why? This article demonstrates that three intervening factors—comparative advantage, the organization of corruption, and the nature of rents—determines the impact of corruption on economic performance, and that these factors can explain the divergent outcomes. The article thereby offers an alternative to statist explanations of the Russia-China paradox.

To evaluate the potential of using electrolyzed oxidizing (EO) water for controlling Escherichia coli O157:H7 in water for livestock, the effects of water source, electrolyte concentration, dilution, storage conditions, and bacterial or fecal load on the oxidative reduction potential (ORP) and bactericidal activity of EO water were investigated. Anode and combined (7:3 anode:cathode, vol/vol) EO waters reduced the pH and increased the ORP of deionized water, whereas cathode EO water increased pH and lowered ORP. Minimum concentrations (vol/vol) of anode and combined EO waters required to kill 104 CFU/ml planktonic suspensions of E. coli O157:H7 strain H4420 were 0.5 and 2.0%, respectively. Cathode EO water did not inhibit H4420 at concentrations up to 16% (vol/vol). Higher concentrations of anode or combined EO water were required to elevate the ORP of irrigation or chlorinated tap water compared with that of deionized water. Addition of feces to EO water products (0.5% anode or 2.0% combined, vol/vol) significantly reduced (P < 0.001) their ORP values to <700 mV in all water types. A relationship between ORP and bactericidal activity of EO water was observed. The dilute EO waters retained the capacity to eliminate a 104 CFU/ml inoculation of E. coli O157:H7 H4420 for at least 70 h regardless of exposure to UV light or storage temperature (4 versus 24°C). At 95 h and beyond, UV exposure reduced ORP, significantly more so (P < 0.05) in open than in closed containers. Bactericidal activity of EO products (anode or combined) was lost in samples in which ORP value had fallen to ≤848 mV. When stored in the dark, the diluted EO waters retained an ORP of >848 mV and bactericidal efficacy for at least 125 h; with refrigeration (4°C), these conditions were retained for at least 180 h. Results suggest that EO water may be an effective means by which to control E. coli O157:H7 in livestock water with low organic matter content.

Purpose The purpose of this paper is to analyze the structure and changes of China’s land system. To achieve this aim, the paper is divided into four parts. The first part gives a brief introduction to the structural characteristics of the Chinese land institutional arrangements; the second part analyzes the reform process of the land system in the past 40 years and its path of change; the third part engages the discussion about the historic contribution made by the land institutional change to rapid economic growth and structural changes; and the final part is conclusion and some policy implications. Design/methodology/approach After 40 years of reforms and opening up, China has not only created a growth miracle unparalleled for any major country in human history, but also transformed itself from a rural to an urban society. Behind this great transformation is a systemic reform in land institutions. Rural land institutions went from collectively owned to household responsibility system, thereby protecting farmers’ land rights. This process resulted in long-term sustainable growth in China’s agriculture, a massive rural-urban migration and a historical agricultural transformation. The conversion of agricultural land to non-agricultural uses and the introduction of market mechanisms made land a policy tool in driving high economic growth, industrialization and urbanization. Findings Research shows that the role of land and its relationship with the economy will inevitably change as China’s economy enters a new stage of medium-to-high speed growth. With economic restructuring, low-cost industrial land will be less effective. Urbanization is also shifting from rapid expansion to endogenous growth so that returns on land capitalization will decrease and risks will increase. Therefore, China must abandon land-dependent growth model through deepening land reforms and adapt a new pattern of economic development. Originality/value This paper gives a brief introduction to the structural characteristics of the Chinese land institutional arrangements, analyzes the reform process of the land system in the past 40 years and its path of change, and evaluates the historic contribution made by the land institutional change to rapid economic growth and structural changes.
