Įvairių dirvožemio drėgmės reguliavimo metodų analizė / Variety methods analises of a dampness regulation of soilGarbačiauskas, Aurimas 15 May 2006 (has links)
This biological preparation is not still investigated in Lithuania. That is why the purpose is to find out the influence of the biological preparation Agricol to fir seedings taken effect and for the distance of their development. Besides, to find out that influence this preparation has for regulation of dampness regime in soil. The article analyses damps regulation of soil using biologic preparation Agricol and it's influence for simple fir's seedings naturalization in the future development of them.

Drėkinimo sistemų poreikis Kauno apskrityje / The Need Of Irrigation Systems In Kaunas DistrictStravinskas, Tadas 14 January 2009 (has links)
Darbe analizuojami Kauno apskrities ūkininkų ūkiai, jų sausinimo ir drėkinimo sistemų poreikis, priklausomybė nuo ūkio veiklos. Analizei panaudoti ūkininkų, užsiimančių žemdirbyste, apklausos duomenys. Aktualiausia problema - išsiaiškinti drėkinimo sistemų poreikį Kauno apskrities žemdirbystės ūkiuose. Siekiant optimaliai padidinti derliaus apimtis, svarbu palaikyti tinkamą drėgmės kiekį dirvožemyje ir visą augalo vegetacijos laikotarpį išlaikyti optimalų dirvožemio drėgnumą. Ypatingai svarbu įvertinti drėkinimo sistemos reikalingumą ūkiui ar įrengta sistema padės padidinti derliaus apimtis. Taip pat aktualu įrengiant drėkinimo sistemas įvertinti ir sausinimo sistemos būklę. Išanalizavus esamą situaciją galima teigti, kad drėkinimo sistemos yra labai svarbios tam tikrų veiklos sričių ūkiams, ypatingai daržininkystei. Šiose veiklose galima žymiai padidinti derliaus apimtis, kokybę, prekinę išvaizdą. / The aim of thesis is to analyze farmers’ farms of Kaunas region, the condition of farms’ drainage and irrigation systems, their dependence on the farms’ work. The questioning data of farmers has been used for the analyse. The most relevant problem is to ascertain the demand of irrigation systems for agriculture of Kaunas region. In order to increase extents of harvest it is important to maintain optimal soil moisture regime during all period of plants’ vegetation. It is particularly essential to evaluate the need of irrigation system to a farm or if equipped systems will help to increase extents of harvest. As well as it is relevant while equipping irrigation systems to evaluate conditions of drainage system. According to the accomplished research about analyzed situation, it might be proposed that irrigation systems are very essential to certain work field farms, especially to vegetable-growing, seed-growing. Extent, quality and marketable looks of harvest might be considerably increased in these activities.

Braškių vandens poreikio tyrimai Lietuvos Vidurio zonoje / Strawberry water requirements in Middle LithuaniaTaparauskienė, Laima 09 February 2006 (has links)
Restoration of Lithuanian independence, land reform, radically changed farming structure and strawberry growing potential has conditioned an increase of modern strawberry plantation. Irrigation is a rather important precondition for the commercial cultivation of fruit and berries in Lithuania. The new farm structure requires new, mainly small-scale irrigation systems. Strawberry water consumption and the soil water dynamics during strawberry growing period stated performing pilot research and additional yield which had been got because of the irrigation influence allows to measure optimal irrigation regime of the strawberry based on research. The aim of the work was to investigate dynamics of strawberry evapotranspiration in the Middle Lithuania and in the course of experiments, with respect to development peculiarities and productivity, to determine optimal irrigation regime for the strawberry grown in loamy soils. In the summary is presented strawberry evapotranspiration results maintaining optimal soil moisture conditions with irrigation; analysis of reference evapotranspiration methods; determination of their interaction degree and evaluation of the possibilities to introduce reference evapotranspiration models in calculation of the evapotranspiration of strawberries; quantitative evaluation of the influence of meteorological factors on the amount of the water consumed by strawberries and analysis of strawberry evapotranspiration calculation methods; evaluation of soil...

Kietųjų kapsulių užpildymo miltelių mišiniais technologijos kūrimas ir vertinimas / Hard capsules filling technology creating and estimationPaulauskaitė, Giedrė 12 August 2006 (has links)
Hard capsules filling machines are useful for some reasons: with them we can quick pack small quantities of powder, can make drugs for clinical trials, also can use them for students learning in university. But in literature we couldn’t find method how to count the right quantity of powder, need to fill in one capsule. For this reason, we perform some experimental works with acetylsalicylic acid, paracetamol and lactose to find out how it does right. During these works, we research how affect powder flow, powders moisture, filling condition, powder particle size to the capsules filling. Also we research is any differences between capsules position in capsules filling machine and its weight. To find is our method right, we made 3 series of acetylsalicylic acid capsules and made uniformity of content and uniformity of mass tests with them. Made accomplished fulfils European pharmacopeia’s demands.
