This study aimed to assess the levels of heavy metals (HM) in sunflower (Helianthus annuus L.) cultivated on agricultural soils in the vicinity of a steel enterprise located in the western part of Galati town, Romania, and the pattern of their bioaccumulation from soil to plant compartments (leaves, seeds). The importance of the study originates from the necessity of understanding the HM pollution in soil-plant systems, especially in an agroecosystem impacted by the activity of ferrous metallurgical industry, and ...

The ultimate goal of this study is to obtain antimicrobial textiles, useful in various skin infections with different bacterial strains, due to the unique properties of contained essential oils, such as: antimicrobial and antiinflamatory effects. Four different matrices of biologic active systems in forms of stable emulsions were used in this study, namely: bee wax ? essential oil, chitosan ? agar ? essential oil, xanthan gum ? essential oil, xanthan gum ? gelatin ? essential oil and four different types of essent...

One of the most abundant renewable resources with a great potential as raw materials for production of fuels and bulk chemicals are carbohydrates derived from biomass. Among these, esters levulinates have been widely used as solvents and plasticizers in food industry or as fuels additives for transportation. The direct synthesis of methyl levulinate from fructose over solid superacid SO42?/TiO2-La2O3 catalyst was investigated in this study. The influence of different reaction parameters such as reaction temperatur...

Latvia is one of the greenest countries in Europe, and one of the advantages it gives is an opportunity to incorporate its nature and naturalness in tourism products. It is important for Latvia as a small country to contribute to the visibility of tourism products, which could promote sustainable economic growth. Solutions could be found within the scope of government policies. One of the objectives is to promote exports of tourism services without causing problems to the natural and social environments. In touris...

Environmental management is aimed at the safe use of natural processes, taking into account the biological features of management and the socio-economic possibilities of the management company. Responsible business contains a set of principles, methods, means and forms of production management, developed and applied at an enterprise in order to improve the environmental efficiency of production. Environmental management includes an assessment of the social and environmental performance of the organization. Environ...

In modern conditions, the main problem is the threat of loss of natural resistance. Environmental responsibility implies the maintenance of a rational system. Such a system contributes to the preservation of natural heritage for future generations. Environmental resources include climate, biosphere, landscape, aquifer. These resources are used to form innovative clusters. They set the conditions and limitations of business activities [1]. Corporate environmental management is designed to effectively manage the ent...

The problem of automatic geophysical facies classification from well logs has played a crucial role in the mining industry from the 1980s to the present day. During this period, many different approaches were proposed to cope with this task; they were based on the methods of machine learning and deep learning. This paper gives a systematic survey of modern effective solutions to the assigned problem. The comparison of the approaches to the solution which are described in the works of various researchers is present...

In the current social and economic context it is necessary to evaluate the directions of administrative-territorial development and socio-economic vulnerability in relation to natural hazards, as the frequency of catastrophic phenomena tends to grow. In order to minimize the loss of human lives and to reduce the economic impact, it is necessary to implement an adequate territorial planning in relation to the spatial distribution of natural disasters. Most settlements from the region of Moldova are located / develo...

The rapid change in the technological paradigma of Russian subsoil users is dictated by sharp changes in the energy policy picture of the world; the increase of Russia's geopolitical loneliness; the introduction of sectoral sanctions; the violation of the mechanism of international transfer of advanced technologies; the unpredictability of the global hydrocarbon market. The negative impact of global trends is complemented by unresolved internal problems of oil and gas companies in the regions of their presence. Th...

Inhalation delivery is a promising route of drug administration, including systemic action. It should be considered that the particles of drug aerosol should have a diameter in the range of 1 to 3 ?m. Microspherical particles based on protein molecules can provide increased bioavailability of drugs with poor water solubility. In the present work, microspherical particles of sodium caseinate with a model hydrophobic drug ? phenacetin were obtained using spray drying method. Average aerodynamic diameter of resulting...

Egypt is characterized by a hot desert climate. Most of the residential building occupants suffering from indoor environment because of the high indoor Temperature and the majority of buildings have poor design related to the climate. This paper investigates different passive design strategies to enhance energy efficient design and increase the performance of thermal comfort in a typical residential building in New Minia, Egypt. The approaches are conducted by computational IDA ICE 4.7.1 program to simulate differ...

At the head of all the activities of society are human resources, they are making technological breakthroughs and the development of economic growth. In the overwhelming majority of cases, the development of new technologies is carried out at the expense of organizations working to improve the economy and technological development; organizations face the difficult task of stimulating human resources for a technological breakthrough. In this article, corporate social responsibility is considered as one of the tools...

In recent years, oppression and even death of Baikal sponges has been noted. To monitor the state of the sponges and find out the reasons for their death, as well as to optimize the cultivation conditions and develop natural remediation measures, it is extremely important to have adequate biotesting methods based on changes in the physiological reaction of the sponges under the influence of adverse factors, including under the influence of various classes of pollutants. In view of the extremely low growth rate, va...

Marble onyx is a banded aggregate consisting of calcite and aragonite of the most diverse colors. Due to its decorative properties, onyx is valued in the jewelry and construction industry. In nature, marble onyx is formed by layer-by-layer deposition of carbonate substance from carbon-calcium dioxide water. It occurs mainly in the areas of young volcanism, rich in thermal springs. In recent years, information has appeared platform manifestations of onyx mineralization. One of these manifestations was found on the ...

The energy system is an area which requires a large enough attention in the process of automation and the use of all the possibilities of producer of energy from renewable sources. It is not enough to produce energy but also to collect and trade to the true value, without being used intermediate bodies for recouping. Drop is a technology that allows users to collect data, information from one or more establishments located remotely and send instructions with limited control by them. The article presents a study wh...

Rapeseed crop is an economical competitive crop which could have a good yield and a good profit to farmers. Due to its biological particularities the rapeseed crop is at the same time the highest risky crop in Europe, especially due to lower percent of emerged plants after sowing or due to lower hardiness during winter. To increase rapeseed resistance to drought and pests attack, during germination, there is a huge need to develop and use a new products based on Gibberellic Acids (GA3) and amino acids for seed tre...

Ash and slag waste constitutes a significant part of the waste of heating and power plant (CHP) complexes operating on solid energetic fuel. For the most part, this by-product does not find further application, accumulating in ash dumps. Meanwhile, taking into account the global trend towards the involvement of ash and slag waste in industrial processing, it is necessary to predict their recycling in Russia. However, for recommend recycling type of ash and slag it is necessary to know their structural and material...
