Rate Of Success

Animal wastes represent a vast untapped source of energy and nutrients which can be recycled by the use of bioconversion processes. Biomass production, improved digestibility, reductions in environmental pollution and cheaper feed bills are some of the advantages of utilizing animal wastes. However, economics, technological developments and the individual requirements of farming operations will determine the rate of success of such systems.

The article describes the essence and content of academic culture as a significant component of national innovation security. The semantic and terminological analysis of the key concepts of the research like «national security», «human security», «human security of humanity», «human capital» were carried out. The concept of «innovative security» is described as a stable, effective provision of country’s innovations in the economy, creation of conditions for modernization of industries, development of priority areas of fundamental and applied scientific research, technical and technological developments that ensure the competitiveness of the country.It was proved that main features of academic culture are the culture of study at the university, ethical values, traditions, norms, rules for conducting scientific research; scientific linguistic culture, professional subculture of the scientific community; social, moral responsibility for the process and results of the research which is formed in the cultural and educational space of higher education institution. The cultural and educational space of the university is described as a component of the development of human capital and one of the factors of national innovation safety. It is noted that universities must clearly show the values of educational services, be centers of academic culture, act on the principles of academic freedom, public responsibility, respect for human dignity and support adherence to academic integrity in research activities. The formation of the researcher’s academic culture in the conditions of the university’s cultural and educational space is defined as a complex, multidimensional, phased process of qualitative changes in the psychological sphere of the individual, taking into account the main provisions of the theory of activity, intercultural communication; the ideas of a humanistic, acmeological paradigm; concept of continuous pedagogical education.

Based on 1990-2007 data in Guangdong China, this chapter studies the correlation of environmental pollution, human capital, and economic growth. The results show that Guangdong’s economic growth deteriorates the environmental quality. Highly skilled human capital is one of the main engines of the economic growth and the growth promotes the human capital’s accumulation. Upgrading the human capital helps controlling pollutant emission and environmental pollution depresses the human capital accumulation. Furthermore, the authors hope that understanding the individual relationships between environmental pollution and human capital or economic growth will help the environmental protection authority or governments in China to make more effective and efficient regulations or policies to coordinate the country’s sustainable development.

Practical Factors

Empirical research into large ensemble performance has crossed many disciplinary boundaries from music education to management studies, and has included the investigation of musicians’ interpersonal coordination and communication, group creativity and decision-making, conductors’ gestures, group musical expression, the social organization of large groups and their leadership, audience perceptions of performances, the individual and social benefits of participation, and rehearsal practices. However, there are still relatively few empirical studies of large ensemble performance, due to the social and practical factors that make it challenging to collect research data from large numbers of people engaged in a complex musical activity. Technological developments have increasingly expanded the research methods available to include sophisticated audio capture and analysis, web-based video-stimulated recall, and motion capture. This chapter discusses the challenges faced by researchers investigating large ensembles and describes some of the technological solutions that are opening up new avenues for data collection and analysis.

Biocrude Oil

Post hydrothermal liquefaction wastewater (PHWW) was generated during biocrude oil production. It contains lots of carbon, nitrogen and phosphorous elements, which can cause environmental pollution and resource waste. Using photosynthetic bacteria (PSB) to treat this kind of wastewater can realize pollutants elimination and resource recovery. In this work, the feasibility of using PSB to treat PHWW was firstly investigated, and the treatment conditions were optimized. Results showed that the PSB can effectively degrade PHWW. The optimal initial COD concentration, inoculum size and light intensity for PSB to treat PHWW were 6000-10000 mg/L, 50 mg/L and 1000-3500 lux, respectively. With the initial COD concentration of 9000 mg/L, inoculum size of 50 mg/L and light intensity of 1000 lux, the COD, NH3-N, TP removal and biomass production reached to 71%, 90%, 47.2% and 773 mg/L, respectively. This showed that using PSB to treat PHWW can be an alternative method for PHWW nutrients recovery and pollutant treatment.

Solid Liquid

Dispersed multiphase flows—the study of the individual or collective motion of a discrete (solid/liquid/gas) phase in a continuous (liquid/gas) phase—has broad implications for health physics, processes in the natural environment, new technological developments (microelectromechanical systems) and many industrial problems. Many of these processes are important in our daily activities. In this paper, a general overview of the papers in this Theme Issue is described and some of the common issues are identified.

Source Sink

One of the hypothesized functions of marine protected areas (MPAs) is to serve as sources of biomass, with biomass spilling over from the reserve into neighbouring, harvested areas. We argue that the net larval flow (from or to the marine reserve) depends on between-area differences in the population-level biomass production rate, whereas the direction of adult flow depends on differences in the biomass standing stock. Hence, an important question is whether population-level biomass production increases (overcompensation) or decreases (undercompensation) with increased per capita mortality. We show that in a consumer–resource context, the source–sink status of an MPA may depend on the details of the individual-level bioenergetics, as well as on the dispersal rates of larvae and adults. We compare two classic bioenergetic models (net-production vs. gross-production allocation). The net-production model predicts that population-level reproduction may increase with mortality (overcompensation), whereas gross-production allocation always results in undercompensation. We show that models often implicitly assume gross-production allocation, thus potentially overestimating the capacity of MPAs to source unprotected areas. We briefly discuss results of two other models (a simplified, logistic model and a size-structured model), suggesting that the relation between overcompensation and the larval sink status of MPAs is general.

Dissolved organic matter (DOM) in the oceans is one of the largest pools of reduced carbon on Earth, comparable in size to the atmospheric CO2reservoir. A vast number of compounds are present in DOM, and they play important roles in all major element cycles, contribute to the storage of atmospheric CO2in the ocean, support marine ecosystems, and facilitate interactions between organisms. At the heart of the DOM cycle lie molecular-level relationships between the individual compounds in DOM and the members of the ocean microbiome that produce and consume them. In the past, these connections have eluded clear definition because of the sheer numerical complexity of both DOM molecules and microorganisms. Emerging tools in analytical chemistry, microbiology, and informatics are breaking down the barriers to a fuller appreciation of these connections. Here we highlight questions being addressed using recent methodological and technological developments in those fields and consider how these advances are transforming our understanding of some of the most important reactions of the marine carbon cycle.

<em>The millennial generation is the generation that has dominated the labor market in recent years. This generation is being faced with various challenges due to technological developments that are happening.</em> <em>Current technological developments are forcing the players in the goods and service industries to innovate in order to be able to increase the competitiveness of companies. Innovative work behavior can be raised</em> <em>by individuals in several ways, one of which is with a proactive personality. This study aims to measure the</em> <em>relationship between proactive personality with innovative work behavior in the millennial generation. The study was conducted on 315 millennials who are full time employees in goods and services companies in the city of Surabaya. Innovative work behavior is measured using the Innovative Work Behavior Scale, which is proven to be reliable (α = 0.760), while the proactive personality is measured using the Proactive Personality Scale that has proven to be reliable (α = 0.734). The analysis in this study uses Pearson's Product Moment analysis with a significance value of 0,000 (p &lt;0.05) which shows the relationship between proactive personality and innovative work behavior in the millennial generation. These results indicate that the higher the proactive personality an individual has, the higher the innovative work behavior exhibited by the individual. The results of this study also found a significant relationship between sex, years of service and age on innovative work behavior</em>
