Probability distributions of wave heights in the Lithuanian coast

Kasiulis, E., Aleksandras Stulginskis Univ., Akademija [2012]

Since discovering that signals of random waves submit to the known laws of probability, this became widely used in engineering and energetics for probability distributions analysis of wave height. From an energetic point of view, it is necessary to know the average wave height in, for example, highly wavy (1% probability), medium wavy (25% probability) or non-wavy (95% probability) years. Wher ...

Lithuanian Agricultural Library

In the period of 1993-1997 61 salmonella strains isolated from adult pigs and piglets on pig-breeding farms of 36 Lithuanian districts were investigated. Pigs on breading farms were most infected with Salmonella choleraesuis serotipe strains - 67,2. From the selected strains S. choleraesuis, S. choleraesuis var kunzendorf and S. enteritidis isolated from pigs on different Lithuanian farms an i ...

Analysis of heating value variations in stored wood

Ciganas, N., Lithuanian Univ. of Agriculture, Akademija et al. [2010]

This paper presents dynamics of calorific value variations in wood grown in Lithuania that can be used for fuel, namely: Scotch pine (Pinus sylvestris), osier willow (Salix viminalis) and silver birch (Betula pendula). Felled wood with a moisture content of Pinus sylvestris – 42.95 %, Salix viminalis – 43.34 % and Betula pendula – 37.82 % respectively, was stored in 3 variants of environmental ...

Estimation of forest parameters using the non-parametric techniques and satellite images at compartment level

Jonikavicius, D., Lithuanian Univ. of Agriculture, Akademija et al. [2010]

This paper discusses the use of medium resolution Landsat TM satellite images to support conventional approaches of Lithuanian forest inventory practices. Estimation accuracies achieved using just field measured sample plots, Landsat TM satellite images and two non-parametric k-nearest neighbour and most similar neighbour estimators were studied at a level of compartments. 19 mature forest are ...

Testing the simultaneous use of laser scanning and aerial image data for estimation of tree crown density

Bikuviene, I., Lithuanian Univ. of Agriculture, Akademija et al. [2010]

This paper introduces the first test results to use laser scanning and high resolution digital colour infrared aerial image data to estimate average tree crown density at a sample plot level. General methodological framework based on two-phase sampling schemes, non-parametric estimators and satellite images as the auxiliary data sets was adopted for the use with airborne data sources. More tha ...

Modelling of the wastewater treatment in the filters of vertical flow with the dolomite powder media

Kazakeviciene, J., Lithuanian Univ. of Agriculture, Akademija et al. [2010]

The possibilities to use other media instead of the sand in the filters of vertical flow are analysed in the article. The media used has to be inexpensive and its possibilities to clean the wastewater have to surpass that of the sand. The modelling of the wastewater treatment in the vertical flow filters was carried out in 2008 at the Water Research Institute of the Faculty of Water and Land M ...

In order to avoid the problem of stoppage in the filters of vertical filtration, we tried to search for the filter media which was coarse and could clean the wastewater to the allowable contamination level. For this purpose the dolomite chippings were chosen and the modelling investigation was performed. Two modelled filters taking 0.2 square m area each were equipped: one was filled with the ...

Research of surface wastewater in the territory of meat processing company

Miseviciene, S., Lithuanian Univ. of Agriculture, Vilainiai [2010]

Pollution and treatment efficiency of surface (rain) wastewater, forming in the production territory of meat processing company LTD ‘Krekenavos mėsa’ (centre of Lithuania in Kėdainiai district), were investigated in the period 2004-2009. On the surface of the company territory the precipitation water turns to surface wastewater, which is collected and sent down to treatment equipment. Wastewat ...
