Blueberry though one of the most valuable berry plants is limited in its occurrence in Lithuania. One of the reason – is lack of local cultivars. Over 1993 – 2004 the largest blueberry germ plasm was established in Kaunas Botanical Garden at VDU. This collection has been used for breeding of new cultivars. Seedlings ‘No.11, ’‘No.16’ and ‘No.17’ were investigated in Kaunas Botanical Garden over 2002 – 2004. The investigation aimed at estimating of productivity, character of fruiting and biochemical composition of berries. The obtained result were compare with those of halth-highbush ‘Northcountry’. Fruiting of 4 – 6 year old bushes was estimated, mean earliness of fruiting, berry size, volume and average yield for 3 seedling numbers were determined. Seedlings numbers ‘No.11, ��‘No.16’ and ‘No.17’might be classified as early cultivars. The main port of the blueberry yield was obtained in the first picking, due to this mechanised picking might be applied. The plants produce tasty, good marketable appearance and biochemical composition. The best marketable appearance typical of ‘No. 17’, the biggest berries – ‘No. 11����. The most productive were ‘No. 16’ and ‘No. 17’, their mean productivity is two times higher than that of ‘Northcountry’.

The tests purpose - to investigate the length and decorative of the preservation to different cultivates of roses blossom, keeping them in 14 C0 and 18 C0 soak water supply water and in solution of Chrysal. The experimentations carried out in the farm of Algimantas Žemaitis in the period of 2003 -2004. The cultivates of Thea hybrida clump Black Baccara, Black Magic, Eldorado, Raphaela, Red Devil, Vevdela, Versilia and clump of floribunda Akito, Gold Strike and Konfetti have been chosen to investigate the preservation of roses blossoms. The general conclusion of influence Chrysal solution: The length of decorative preservation of roses blossoms has been durable when we were keeping them in soak solution of Chrysal, neither the roses witches have been soaked in the water supply water. The cultivates from investigated of ten roses Raphaela have been blossomed durably and Gold Striks - shortly. In 14 C0 the cultivates of roses Raphaela preservated 16,1 days and Gold Strike – 13,1 days, keeping them in woter, 19,1 and 15,7 days accordingly in solution of Chrysal. In 18 C0 cultivates of roses Raphaela preservated 15,2 days and Gold Strike - 12,1 days, keeping them in woter, 18,0 days in solution of Chrysal. The cultivates of roses Black Bacara has been blossomed shortly – 14,0 days, keeping them in solution of Chrysal.

The investigations were carried out in the collection pears garden of the Lithuanian Institute of Horticulture in 2004.The aim of the work was to evaluate the manifestation of biological and morfometrical charakteristics of pears varieties of different origin to distinguish the desireable charakteristics and to recommend the varieties that are suitable for further selection in Lithuania. 161 pear cultivars were investigated. Phenological phases, their begginnig and duration, blossom injuries caused by spring frost, end of vegetation and fruits morphometrical parameters were evaluated. The latter two characters were estimated according to the scale 0 – 5: 0 – flowers not injured, 5 – all flowers injured in inflorescence. At the end of vegetation: 0 – leaf fall not started, 5 – all leaves are fallen. It was ascertained that 2,5  of investigated pear cultivars came into bloom on April 30. the phase of full bloom lasted for 12 days. On May 14 air temperature 1,5 m above land during spring frost dropped up to – 3,1 C degrees. Twelve cultivars did not show any symptoms of injury by frost, but blossoms of 12 ones were heavily damaged or killed. At the beginnig of November leaves were not fallen on fruit trees of 50 % pear cultivars and only 8 – 10 % cultivars ended vegetation.

For the first time it has been conducted an integrated research of possibilities to apply different kinds of fatty wastes for biodiesel fuel production. For this reason esterification process of oil an fat rich of free fatty acids by using acid catalysts and further transesterification of the obtained product until standard requirements for biodiesel fuel have been fulfilled. Intersolubility of different components of multi-component biofuel systems, and limits of stability were investigated. Emissions of the biodiesel fuel were analyzed and fuel biological decomposition in the environment was studied. Life cycle parameters of the suggested biodiesel fuel production process were determined.

In the dissertation evaluated frost influence to the change of physical–mechanical properties of the reinforced concrete slabs for earth dam slope protection. Established ice thermal expansion linear load acting the slabs and proposed more exact calculation of this load. Evaluated deterioration indices and defects influence to slabs state and durability.

Magistro darbo objektas – Lietuvos universitetų leidyklų veikla. Darbo tikslas – atsižvelgiant į Lietuvoje po 1990 m. įvykusius pokyčius ekonomikoje bei švietimo sistemoje, išanalizuoti Lietuvos universitetų leidybinės veiklos evoliuciją, įvertinant kiekvienos aukštosios mokyklos leidyklos veiklą ir leidybinį repertuarą. Leidyklų veikla tiriama 1991-2003 m. laikotarpiu, nes 1990 m. žymių pokyčių universitetų leidyboje neįvyksta bei nėra statistinių duomenų. Pagrindiniai darbo uždaviniai: aptarti universitetinės leidybos raidą pasaulyje ir pagrindinius jos veiklos principus; išanalizuoti Lietuvos universitetų leidyklų statistinius duomenis, nustatyti lyderius ir jų veiklos specifiką; išanalizuoti universitetų leidinius, jų repertuarą. Prieita prie išvados, kad steigiant universitetus, taip pat buvo kuriami leidybos skyriai, kurių pagrindinė paskirtis – leisti bei platinti mokslo ir mokomąja literatūrą akademinei bendruomenei. Leidyklos yra nepelno siekiančios organizacijos, gaunančios finansavimą iš įvairių Respublikos ministerijų, komisijų ir kitų rėmėjų bei universitetų biudžetų, kuriems yra pavaldžios. Kiekviena universiteto leidykla savo leidybinėje veikloje orientuojasi į aukštojoje mokykloje dėstomų studijų programų aprūpinimo literatūra bei akademinės bendruomenės informavimo ir jos narių darbų publikavimo poreikius. Dauguma universitetų leidyklų įsteigė mažas spaustuves ir įsigijo įrangą, kuri paspartino ir atpigino knygų leidybą, tačiau dalį spaudos darbų užsako...

Publishing offices activities are studied during period of 1991 – 2003, because there wasn’t any essential shift in university publishing and there is no statistical information presented about 1990. The main purpose shall be obtained by accomplishing these tasks: to dispute about university’s publishing processes and the main principles of it’s activities in the world; to analyze statistical information of publishing offices of the Lithuanian universities, to estimate leaders and the main principles of their activities; to analyze the publications and repertoire of universities. To conclude, every established university had it’s own publishing department, which was to publish and distribute scientific and educational literature to academic society. Publishing offices are non-profit organizations, which are financed by various Republic ministries, committees and other supporters also university budgets to which they are subordinated. Most of universities publishing houses established small printing houses and obtained equipment, which made printing quicker and cheaper. All Lithuanian universities concern about distribution, but this sphere is too complicated to many of them. The... [to full text]
