  • Research Into Biological Characterictics of Dried Sapropel

    Tretjakova, Rasma; Grebeža, Jūlija; Martinovs, Andris (2015)
    Microbiological characteristics of dried sapropel of Lake Rušona and Lake Ubagova and concrete containing sapropel and hemp sheaves (Ubagova Lake) have been studied. The antimicrobial activity was studied by thereference test culturesStaphylococcus aureus  ATCC 25923, Salmonella enteritidis ATCC 13076, Enterococcus faecalis  ATCC 29212, Bacillus cereus  ATCC 10876, Escherichia coli ATCC 25922, Candida albicans ATCC 10231. Antibacterial activity on Staphylococcus aureus reference test cultures...

    Determining the Isotopic Composition of Nitrate in the River Daugava and Loads of Nitrogen to the Gulf of Riga

    Skute, Arturs; Osipovs, Sergejs; Vardanjans, Davids (2015)
    The Daugava or Zapadnaya (Western) Dvina River belongs to the Baltic Sea basin. The length of the river is 1,005 km with a drainage area of 87,900 km2. It crosses three countries: Russia (323 km and 18,500 km2), Belarus (328 km and 33,100 km2) and Latvia (352 km and 24,700 km2). Water samples were collected at three points with the following coordinates: Kraslava, Daugavpils, and Riga and distance from the river mouth 320, 255, and 20 km respectively. Discharge measurements by use of acoustic...

    Floodwater storage capacity of the Middle Daugava floodplain

    Gruberts, Dāvis; Vilcāne, Kristīne (2015)
    This study highlights the flood risk prevention services provided by the Middle Daugava river-floodplain system located downstream from Daugavpils City. Today, it acts as a principal storage area for floodwaters of the Daugava River during the spring floods, therefore diminishing the risk of flooding and related costs for urban municipalities like Jēkabpils and Pļaviņas located further downstream. Statistical analysis of hydrological data records of the Daugava River at Daugavpils and Jēkabpi...

    Path Planning Usage for Autonomous Agents

    Valbahs, Edvards; Grabusts, Peter (2015)
    In order to achieve the wide range of the robotic application it is necessary to provide iterative motions among points of the goals. For instance, in the industry mobile robots can replace any components between a storehouse and an assembly department. Ammunition replacement is widely used in military services. Working place is possible in ports, airports, waste site and etc. Mobile agents can be used for monitoring if it is necessary to observe control points in the secret place. The paper ...

    Modeling of time dependent thermal process in sliding electrical microcontact

    Ilyin, Alexander; Plokhov, Igor; Savraev, Igor; Kozyreva, Oksana (2015)
    Temperature has great influence on mechanical, electrical and chemical processes that occur in transition layer of sliding contact. The aim of the research is creating a three-dimensional finite-element model for calculating time dependent thermal process in sliding electrical microcontact.The article starts with the description of the contact element representing a discrete microcontact and physics in it.  Then the authors suggest use modern simulation software COMSOL Multyphisics for modeli...
