Today the concept of e-commerce has become commonly used, and e-commerce has become an integral part of commercial transactions. An increase in the number of global Internet users is the driver of increase in the number of e-commerce transactions. The introduction and role of e-commerce is not well-understood by any manager of a small and medium enterprise. It takes time and money to introduce e-commerce in business, especially in retailing. Enterprise managers need a clear e-commerce introduction strategy to see ...

The oceans cover more than 70% of the Earth's surface. There is a constant material andenergetic interaction of the ocean with the environment. This process determines themodification of the basic properties of its waters, which, in turn, determines the climatechange on Earth. Climate change remains today one of the most discussed issues in bothacademia and the public. The Intergovernmental Oceanographic Commission ofUNESCO responsible for supporting global ocean science and services pays greatattention to the imp...

Proposed within the framework of the conducted study were options for producing the titanium trichloride, a precursor for the synthesis of titanium dioxide nanoparticles to produce dye-sensitized solar cells (DSSC). Optimal concentrations of the initial titanium tetrachloride solution were identified, which have a major effect on the reduction process and the stability of resulting titanium trichloride solutions. Possible synthesis and destruction mechanisms of the titanium trichloride under the influence of vario...

Modern professional geographic information systems (GIS) include a wide range of well-tuned powerful algorithms for processing and analyzing spatial data, but their use is hampered by the specifics of the information environment in which the GIS data operate. At the same time, web technologies can provide an information environment that will allow users to access GIS software from anywhere in the world. The integration of GIS and web technologies provides greater opportunities for collecting, accumulating and proc...

Increasing the number of cars in urban areas and the development of a variety of production technologies involving the use of fossil fuels in the urban environment are leading to a significant increase in air pollution. As air pollution with heavy metals and other chemical elements increases, air quality is deteriorating. Poor air quality, in turn, causes a number of different problems for human health, causes poor feeling and reduces life quality in total. The method of analysis of snow samples is one of the meth...

In absence of core samples and open-hole well-log data, the broken bits of rock removed from the borehole during the drilling process represent in many cases the only lithological data that is recovered from a well. The main objective of this study was to build up a lithological profile and to use the data in order to improve the knowledge about the local geology (Quaternary deposits). Lithological information at shallow depth is generally used to better understand the local site effects, known to play an importan...

The optimal ratios of the components of the WC–Co-CrB2 system have been established, at which a finel...

Peptide-drug conjugates are therapeutic agents that combine one or more drug molecules with a peptide through a biodegradable linker. Even if the peptides used in synthesis of such conjugates have a smaller pharmacological action than the small molecule of organic drug, they easily penetrate the membranes and then bind to receptors. Peptide-drug conjugates are used in various fields, such as: (i) anticancer therapy; (ii) antimicrobial application; (iii) anti-inflammatory application. In the last decades, researche...

Surface mining method enormously affects the environment in terms of fugitive dust emission than underground mining method. High mechanization in mining operations leads to add heavy load of dust to the surrounding area. Dust not only deteriorates the environmental air quality in and around the mining site but also creates serious health hazards. During coal mining activities, large quantities of coal dust, ashes, polycyclic aromatic hydrocarbons, and heavy metals are released into the environment, forming a compl...

Landsliding is among the most massive and active exogenous processes. Now they increasingly manifest in permafrost zones due to climate change and require close attention and careful study. Analysis of the territory most prone to these processes, one of the largest islands in Northern Canada, Banks, confirmed earlier studies of landslide processes in this zone, which indicate a relationship between increased activation of landslides and abnormally warm summers. The study and assessment of the landslide focus param...

The article considers the problem of predictive estimation of deformation processes of geotechnical control objects. It is noted that the main task of geotechnical monitoring is the rapid identification and geodynamic forecasting of geological processes that may affect the safe state of life-supporting and man-made objects, in order to timely develop and take measures to prevent and eliminate emergency situations. One of the most effective ways to timely predict the beginning and activation of deformation processe...

Records of the magnetometers responding to the effects of big earthquakes were noticed more than a hundred years ago. Even then began to dispute what caused these effects: mechanical vibrations of instruments or electric or magnetic oscillations generated by the earthquakes. In Panagjurishte (PAG) observatory we have great opportunity to shed light on this issue because we have four important instruments installed on the site - three different types of magnetometers and one seismometer. Three large earthquakes wit...

Global seismic risk and vulnerability to earthquakes are increasing steadily as urbanization and development occupy more areas that a prone to effects of strong earthquakes. The assessment of seismic hazard and generation of earthquake scenarios is the first link in the prevention chain and the first step in the evaluation of the seismic risk. The territory of Bulgaria represents a typical example of high seismic risk area in the eastern part of the Balkan Peninsula. Over the centuries, Bulgaria has experienced st...

Ecoethics and its various forms are an important phenomenon today. The bad ecological situation and the threat of the ecological collapse of the planet have been the subject of reflection by many theorists.
