Transplantation experiments with Neckera pennata and Lobaria pulmonaria were conducted in nemoral Woodland Key Habitat and managed forest (in total 38 trees) in Latvia. Elastic cotton bandage was the best method for the present transplantation experiments. Dispersal and establishment limitation were found to be crucial for N. pennata and L. pulmonaria distribution between forest stands. Source

Artificial composite materials are currently being produced in large quantities, they are diverse and they are widely used in the economy. There have been extensive theoretical and experimental studies of different types of components, developed the calculation methods of composites production with predefined properties. At the same time industry produces a lot of mineral and polymer waste, which are practically technogenic resources, but their use is currently at quite low levels. The paper examines the possibilities to use technogenic resources- mineral (such as ash and clay) and organic (polymers -PET containers) for producing qualitative composite materials. For this purpose theoretical analysis and calculations of the physical properties of components and process parameters that determine the operating characteristics of the composite material were carried out. Composite-forming process efficiency determinative parameters were analysed: adhesion, the specific surface energy, specific free surface, adsorption capacity and the degree of dispersion of the particles. The role of external factors in processing of composite were examined – temperature, concentration of components. The characteristics of prepared samples of composites showed the possibility to use these waste for the development of qualitative products for different purposes. © Rezekne Higher Education Institution (Rēzeknes Augstskola), Rezekne 2015.

In the sawmill industry in Latvia the roundwood represents about 70% of the total production cost. The quantity measurements of the round wood are required throughout the logic chain of wood from forest to the sawmills but inspite of a large proportion of the total cost the term “true volume” of roundwood is equally actual for supplies and processors of wood. The roundwood volume results differ measured the same load by measuring the diameters of log in short intervals using harvester measurement systems and in sawmills by measuring the diameters of log in short intervals using electronic 3D systems or measured manually using the most accurate method according to the requirements of standard LVS 82:2003 by measuring top and butt diameter. This means that it is a great interest in industry to develop the measurement methods and systems to have a lower cost and more efficient algorithm to determine the wood volume. The purpose of this study is to compare the wood volume calculation results made by the most accurate manual and automatic measurement methods and give the recommendations for minimizing difference between them. The research is a continuation to the work done in the project „Harmonisation of piece-by-piece measurement methods of roundwood approved by Standard LVS 82:2003 „Apaļo kokmateriālu uzmērīšana” (Miklasevics, Z., 2013). © Rezekne Higher Education Institution (Rēzeknes Augstskola), Rezekne 2015.

Research of different studies related to collaboration municipality ─ university allows to establish a fact that it is very important for both partners and has distinctive forms. The core questions of this research are as follows: Is the regional university significant player in regional sustainable tourism development? What forms of collaboration among regional university and municipality are possible? The aim of this research is to examine the experience of regional university in sustainable tourism development in regional area. This research is performed on the illustration of collaboration among regional university (Rezeknes Augstskola) and Dagda county, which is one of the 19-th rural county in Latgale region. A new approach to the collaboration municipality ─ regional university is offered taking into account the possibilities of regional university in improvement of human resources capacity, in improvement of municipality administrative capacity, and in development of sustainable tourism products. The offered approach was set up by taking into account the interests of all stakeholders in this area. © Rezekne Higher Education Institution (Rēzeknes Augstskola), Rezekne 2015. Source

The electronic commerce has become an integral part of the global economy during the last decade. The most obvious indication of the importance of electronic commerce in the world economy is rapidly increasing Internet use in trade and other sectors. The successful growth of e-commerce promotes the use of other electronic media, as well as it is perspective for development of territories located in backcountry and remote regions. In the result of the Internet and electronic commerce technological development there can be observed changes also in the business environment. In these circumstances successful strategies applied in different levels and sectors for the implementation of the most modern information technology achievements, as well as for the development of professionals with appropriate knowledge, expertise and skills, are becoming increasingly important for the development of electronic commerce in Latvia. The article will view the current situation, will explain the main limiting factors and advantages for successful development of the electronic commerce in Latvia. © Rezekne Higher Education Institution (Rēzeknes Augstskola), Rezekne 2015.
