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 ...

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 ...

The aim of the study was to investigate the properties of hyperspectral reflectance data of Scots pine (Pinus Sylvestris L.) and Norway spruce (Picea Abies L.). The hyperspectral reflectance data was obtained under laboratory conditions from the last season’s needles of healthy 20 year-old trees from the same site. Hyperspectral data was acquired using Themis Vision Systems LLC VNIR 400H porta ...

Distribution and status of common juniper (Juniperus communis L.) in Lithuanian pine stands

Vaitkeviciute, R., Aleksandras Stulginskis Univ., Akademija [2012]

Distribution and status of common juniper (Juniperus communis L.) in Lithuanian Pine stands are investigated in the study. The research was conducted in pure pine stands on sites with normal humidity and poor fertility in South – South Eastern parts of Lithuania. 40 stands were selected for data collection. Temporary rectangular sample plots with area of 10 square m were selected. According to ...

Thermal weed control in Norway spruce (Picea abies (L.) H.Karst.) nursery

Silingiene, G., Aleksandras Stulginskis Univ., Akademija et al. [2012]

Growing of economics and new technologies has caused the environment pollution and more intensive use of natural resources. The principles of stable and balanced forestry became more and more important. Ecologization forests economy directly and indirectly impacts environment, water, air, landscape. It is not allowed to use chemicals in ecological farms. In Lithuania the number of ecological f ...

Regulated streams rehabilitation using bioengineering methods

Maziliauskas, A., Aleksandras Stulginskis Univ., Akademija et al. [2012]

Within several decades many natural Lithuanian rivers were straightened and adapted for needs of soil drainage. By 1998, 63.4 thousands kilometres of trenches of which approximately 46 thousands kilometres were regulated rivers and streams were excavated. It is calculated that trenches of regulated rivers and streams currently cover 82.6, and natural – only 17.4% of total rivers network. While ...

The negative impact of agricultural pollution with biogenic materials on surface water bodies is a relevant problem. This problem is addressed by limiting or prohibiting certain activities in the so called buffer areas. The biogenic materials are carried by surface or groundwater runoff. Water infiltration is influenced by the lithological composition of sediments. River basins of sandy lithol ...

The influence of different humus layers on the drainage runoff during different seasons

Miseckaite, O., Aleksandras Stulginskis Univ., Akademija et al. [2012]

Hydro-physical properties of heavy or presses soil as well as water regime may be improved by various ways, taking into account the texture of soil and climatic conditions. Drainage is the tool for productive farming and economic benefit generation. Hydrological activity of drainage typically depends on project installation quality, anthropogenic and climatic factors. It is important to assess ...
