• Monitoring of the quality of ambient air using high volume air sampler

    pg(s) 51-55

    The quality of ambient air is a noticeable demonstration because the ambient air plays a cardinal preface on the human activities and most of environmental processes. The monitoring of the quality of air is an important part of the pollution control because the ambient air was confirmed as an affected branch on the earth from both anthropogenic activities and natural phenomena. In the existing investigation, there were expected to test the selected important air quality parameters of the ambient air at around the Peradeniya region in Sri Lanka which is known as relatively populous region with the traffic. The ambient air samples were collected through a glass fiber filter paper which was attached to the high volume air sampler and both PM10 concentration and concentration total suspended particles (TSP) of the ambient air were determined using weight differences of air collection bottle and filter paper. Beside of that the lead (Pb) concentrations and NOX concentrations of the ambient air were investigated using hot acid extraction method while having the contribution of atomic absorption spectrometer (AAS) and of absorbing method in to a liquid with the aid of UV- visible spectrometer. As the results, there were obtained 0.0141 ppm of PM10 concentration, 0.0214 ppm of total suspended particles (TSP) concentration, 0.151 μg/m3 of NOX concentration and 0.015μg Pb/ m3 of lead (Pb) concentration of the ambient air at around the Peradeniya region at that moment. When comparing of those results with the air quality standards and norms, it was identified the non hazardous atmosphere at the selected region at that occasion.

  • Radical innovations as a drive of Industrial Revolutions

    pg(s) 25-28

    The purpose of this publication is to elucidate the nature of radical innovations as drives of various industrial revolutions, as well as the conditions that led to their emergence. They incorporate substantially different technologies from existing ones and meet the needs of consumers in a new way and better than the current ones.
    This article will discuss factors that can be used to evaluate an innovation as radical. A new view of Industrial Revolution will be presented, explaining critical factors and their relation to sectors of production. An invention may lead to the production of a new, unknown product at a certain time or to the provision of an unknown service. The use of these unfamiliar products or services on the market is characterized as a radical innovation. Relevant radical innovations in turn lead to industrial revolutions. It is argued that a paradigm shift takes place and we call it Industrial Revolution.

  • The impact of global change on consumer preferences of the Moravica District

    pg(s) 20-22

    The aim of the research, the results of which are presented in this paper, is to research the consumer preferences of the Moravica District towards the consumption of domestic and foreign products. As globalization alters market conditions, creates new sources of competition, it is impossible not to think about protecting domestic products and the impact of the increased import of foreign products on the preferences of domestic consumers. Liberalization, as a regulator of market, certainly influences the need to create mechanisms for the protection of domestic production, and the changed consumer preferences are an important factor in monitoring and defining new protection measures so that domestic producers of the Republic of Serbia are ready, primarily for the European market. For this reason, we decided to investigate what consumer ethnocentrism is like in the central part of the Republic of Serbia, in the Moravica District. As the results show, the challenges posed by globalization have greatly influenced consumer attitudes and changes in attitudes towards ethnocentrism.

  • Conceptual model for investigating the innovation activity of enterprises

    pg(s) 17-19

    The paper presents a conceptual model for investigating the innovation activity of enterprises from the wine industry in Bulgaria. The study aims to submit a unified methodological framework for application by experts in researching, analyzing and benchmarking the innovation activity in the sector. Many researchers confirm that different innovation models are appropriate for different sectors, regardless of best practices in innovation management, and it all depends on the specificity of innovation and its relationship to sector specificities. Thus, the examination of wine sector requires a specific approach and an empirical research, based on own questionnaire focused on the individualism and the need to study the innovation niches and opportunities of wine sector.

  • Оn predictability of precious metals towards robust trading

    pg(s) 14-16

    Large amounts of liquidity flow into several precious metals every day. Investment decisions are mainly based on predicting the future movements of the instrument(s) in question. However, high frequency financial data are somewhat hard to model or predict as stochastic processes and many other random factors are involved. It would be valuable information for the investor if he or she knew which precious metals were quantitatively more predictable, that would also be a good basis for more robust trading decisions. The objective in this study is to build predictive models on high frequency precious metal data and compare predictabilities of different metals using only past price and volume values which should be a basis for robust trading decisions. The data used consist of various frequencies from 1-minute to 4-hour covering a period of almost 20 years for each instrument and frequency. Artificial Neural Network (ANN) and Gradient Boosted Decision Tree (XGB) methods are applied. Comparable results are achieved.

    The increasing water deficit requires studies to optimize irrigation regimes and water-saving technologies to achieve economy of irrigation water at an acceptable yield level.
    In order to establish the irrigation regime in the field of “Chelopechene” Experimental Field, Sofia, there have been researches, examining different regimes – from full satisfaction of the daily needs of culture for water to irrigation with reduced by 20% and 40% water application rates.
    On average, over the survey period, the highest yields were obtained with the irrigated wit 100% water applicatipn rate. Reducing the irrigation rate leads to a corresponding reduction in yields and affects the quality of production. The application of regimes of irrigation with reduced iwater applicatipn rates is recommended  only in the case of water deficiency.

    In the paper, the current situation in the production of crop growing by-products in Ukraine is examined. The potential output of crop growing by-products in various regions of Ukraine, part of which could be allocated for energy production, is determined. The fuel properties of the main types of biomass are presented. The state-of-the-art approaches to the use of straw and plant residues in agriculture are analysed. The possible ways of utilising straw and plant residues in crop growing for maintaining and regenerating the fertility of soils, in livestock husbandry as bedding and a supplement to coarse fodders and in heat power industry as an energy source for the production of thermal power are established. The state-of-the-art technologies and machinery for the rational use of straw and plant residues are described. The need for additional research into what plant residues and what quantities of them can be reasonably used for the fertilisation of soils, taking into account the saturation of the crop rotation systems with cereal crops, the limitation of the phytopathogenic load on grain varieties, the development of weeds, the management of the soil’s nitrogen status under different soil and climate conditions.
