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.

With unprecedented number of tourists spotlighted by the leading international journals Georgia wins hearts of millions and becomes a revelation for the USA and Western EU countries.
This paper assesses current situation in Batumi Port that serves small cruise ships and explores potentials of cruise tourism development based on statistics, industry experts and investors reviews. The article uses a mixed method, a combination of qualitative and quantitative data analysis.
The findings show how Black Sea region will benefit from country’s cruise tourism development. Results of the study can be applied as basis for investment analysis of Georgian cruise industry
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.
Energy efficiency is a new domain in our country, so it is very much realistic and possible for us to succeed in implementing this field.The first EU-wide energy efficiency target was set in 1998. Member states agreed to improve energy efficiency by 1 percent a year over twelve years. Pristina Regional Water Company Utility is one of the largest companies in the state of Kosovo. Regional Water Company “PRISHTINA” cover 60% of the total population of Kosovo., with 8 municipalities included capital of Kosovo, Prishtina.This paper discusses energy issues facing public water utility sector, exactly for Regional Water Company “PRISHTINA”, steps that responsibility personnel can take to understand and reduce their energy use and costs, and funding resources for energy efficiency. Main focus in this paper is to perform possibilities for increasing energy efficiency of the Pumping Station in Milloshevë which supply with raw water Treatment Plant in Shkabaj, Kosovo.
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.
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.
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 influence of transnational corporations on the economy of developing countries (Contemplating the example of how the Coca – Cola Company influences the economy of Ukraine)pg(s) 9-13
Transnational corporations’ manufacturing and commercial activities are connected to national and regional markets. Taking this fact into account, the authors identify the main causes of the active development of transnational corporations around the world and determine five levels of economic growth of developing countries. The authors also consider directions of transnational corporations’ influence on developing countries and inquire institutional means and methods of regulating the influence of transnational corporations in Ukraine. Attractive sectors of the Ukrainian economy for transnational corporations’ activities are proposed, the Coca-Cola Company’s activities performed in Ukraine are analyzed, and conditions for further development of transnational corporations in Ukraine are named in the paper.
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.
The development of agricultural service co-operatives in Ukraine is one of the priority directions of the state agricultural policy. The cooperation of small and medium-sized agricultural producers in the dairy, horticulture, vegetable and grain sectors is the key to not only economic, but also social development of rural areas. Increasing the competitiveness of farmers involves significant investments into infrastructure and technology, while the cooperative model enables farmers to receive high-quality technical and logistic services at affordable prices and with affordable start-up investments.
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.
The present article presents in detail the concept of ports connectivity of the ro-ro shipping networks in the Black Sea region. The existing ro-ro services in the region are studied in terms of transportation availability, frequency and capacity. A set of port connectivity indices is applied for measuring the interconnections between the ports in the region via ro-ro services. The results demonstrate that the roro shipping network in the region has a potential for development and despite the low cargo volumes, low level of capacity utilization and lack of efficient hinterland connections of ports.
