    The aim. To analyze the links between pregnant women 's nutrition and their health literacy. Research methods. A quantitative study was conducted, the study sample consisted of 409 women. An online survey have been selected for the study, and the HLS-EU-Q16 questionnaire determined the health literacy of the subjects. The research data was processed with statistical data analysis SPSS 24.0 program. Statistical methods used – average and standard deviation, Chi-square test, Kruskal-Wallis criteria, Spearman correlation analysis. Results. When examining the relationship between pregnancy weight gain and health literacy index a tendency has emerged that the higher the health literacy index, the lower the weight gain during pregnancy. Analysis of the study data found that some dietary supplements are more commonly consumed by women who are married or living with a man. Sweets were consumed significantly by women with higher education. Beef was consumed more by pregnant women living in rural areas. Conclusions. Most pregnant women give up animal foods, sugar, as well as uncooked foods during pregnancy, eating three times a day, taking folic acid immediately after learning that they are pregnant. The health literacy index still remains low enough for pregnant women. The majority of pregnant women have limited health literacy

    There are many areas in the world where scarcity of freshwater are threatening the human population. So humans have to look for solutions to replace freshwater when use of it is not necessary. This also has an effect to aquaculture – more and more farmers are farming freshwater fish in brackish water. Many authors have demonstrated the benefits of brackish water for fish growth and other physiological functions. Nile tilapia (Oreochromis niloticus) is valuable fish for its tolerance to high temperatures, salinity, low amount of dissolved oxygen. They are fairly easy to farm and the quality of the meat and the taste is good. But, despite all the qualities, farmers in Lithuania do not choose to farm these fish. The aim of this study was to evaluate the effect of brackish water on the efficiency of Nile tilapia aquaculture technology. To achieve the goal an experiment was conducted in the Laboratory of Fishery and Aquaculture of the Marine Research Institute of Klaipeda University on August 5 December 18, 2020. During it, three separate recirculating aquaculture systems were constructed from system B. One such system consisted of three tanks. Tank volume – 2,83 m3. Total amount of biofilter filler – 130 L, water inflow – 36 L min-1. All tanks were equipped with the same bio and mechanical filters, oxygen diffusers, the room is heated by heaters. In the experiment water of three different salinities were used: fresh water (0‰), water from the Baltic Sea (6‰) and diluted sea water (3‰). The remaining three basins are used as reserve tanks for storing and diluting seawater. Seawater is pumped to the laboratory from the shores of the Baltic Sea, and fresh water is obtained from a well. Nile tilapia were sorted and distributed into tanks. At the beginning of the study, the average fish weight was: 0‰ – 84,4 ± 19,51 g, 3‰ – 81,28 ± 22,31 g, 6‰ – 84,08 ± 16.47 g, stocking density - 0‰ – 8,08 kg m-3, 3‰ ir 6‰ – po 8,22 kg m 3. Fish were acclimatized for three weeks, their health and behavior were monitored. Water quality parameters were measured daily – temperature (°C), dissolved oxygen content (%), pH. Tests of water saples from each system were conducted to determine the amount of ammonium (NH4), nitrite (NO2) and nitrate (NO3) in the water. Dead fish were counted. During the experiment, approximately every three weeks, 30 fishes were randomly caught and measured from tank. Caught individuals were placed in plastic buckets filled with water. If present, juveniles were collected. Eggs and larvae were photographed, the amount was counted from the photo and fry was counted by transferring from one container to another. Counted juveniles were released into individual aquariums filled with water of appropriate salinity. Adult individuals were weighed, the total length (L) and the length to the caudal fin (l) were measured. During the last two measurements, the sex of the fish was determined according to the shape and size of the papilla and the urogenital organs. A toluidine blue solution diluted with distilled water was used for determination of gender. At the end of the experiment, the following were calculated: mean fish weight, specific growth rate (SGR), weight gain (Δw), feed conversion ratio (FCR), initial and final Fulton coefficients (Ki and Kf), final biomass, and survival. A respiration experiment was conducted using Nile tilapia juveniles to determine their metabolic rate (MO2). A PyroScience FireSting O2 optical oxygen meter was used for the respiration experiment. Experiment was conducted in two trials. First one: water of different salinity (0‰, 3‰, 6‰) was added to each respirometry system, the water temperature was 22 °C. Juveniles from 0‰ aquarium were placed in 0‰ system, from 3‰ to 3‰ systems and from 6‰ aquarium to 6‰ system. Second trial: water of different salinity (0‰, 3‰, 6‰) was added to each system, the water temperature was 23 °C., Juveniles from 0‰, 3‰ and 6‰ aquariums were placed in each system. Intermitted respirometry method were used: when the amount of oxygen dropped ~ 2 mg L-1 from the initial amount, the water was renewed – the former water was poured out of the bottle and a new, well-oxygenated water was added. Fry in the bottles were not changed. After the experiment, the fry was weighed (g). A study of physico-chemical properties of fish meat was conducted. After the growth experiment, three females and three males were randomly transferred from each pool to the reservoirs of the system with water of appropriate salinity. A total of 54 tilapias were used in the study. Skinless fish fillets were used for the study, each piece was weighed. A total of 18 samples were taken, 6 from each system (3 females and 3 males). Due to the low weight of the female fillets, the samples were pooled – one sample consisted of three fish using one half of their fillets. Samples were kept on ice until they reached the laboratory. The study of physico-chemical properties of meat was performed at the Veterinary Academy of the Lithuanian University of Health Sciences. The percentage of protein, fat, ash, dry matter, water binding and water content of the sample was determined and the pH was determined. In this study were found that water salinity had a statistically significant effect on dissolved oxygen content, pH, and nitrite content in water. Also, due failed adaptation of freshwater recirculating aquaculture system to the brackish water, the water quality deteriorated during the study, especially in the 6 ‰ system, which affected other results. Growth and feed conversion ratios did not differ statistically significantly under different salinity conditions. The worst survival was in the 6 ‰ system due to deteriorating water quality during the study, and the best in the 0 ‰ system. Gender had a statistically significant effect on fish weight, with the final weight of males being 54% higher than females. Brackish water conditions did not significantly affect the spawning of Nile tilapia females, larval and fry amount. There were also no statistically significant differences in the measurement of pup metabolic rate. When assessing meat quality, there was a statistically significant difference in meat pH and water content between systems. Water content in fish meat also differed statistically significantly between the sexes

    This master’s degree dissertation’s aim – analyse Borisas Dauguvietis play’s “Žaldokynė” production history and comedy expression by revealing the reasons behind the play’s popularity and touching on the consistent evaluation criteria on humour placed by Lithuanians. Study object – comedy expression Borisas Dauguvietis play “Žaldokynė”. The study involves observations on the evolution of comedy in the Lithuanian Theatre, definitions about laughter subject, laughter object, comedy concepts. Interfaces and differences between traditional (classical) and modern comedy are discussed. While analysing mentioned aspects, it is trying to discover how the understanding of humour by the Lithuanian nation is changing during the existence of “Žaldokynė”. To reveal the popularity phenomenon of Boris Dauguvietis play “Žaldokynė”, which has been shown on Lithuanian stages for more than 60 years, the dramaturgy, directing and acting phenomenon manifestations in the play are analysed. It is trying to find out how “Žaldokynė” phenomenal popularity is being perceived by experts directly related to the creation of the play: actor, who played Motiejus Sapiega (violinist in the country) Adolfas Večerskis in “Žaldokynė”, directed by Kazimiera Kymantaitė in 1975 and Jonas Buziliauskas, who directed “Žaldokynė” at the Žemaitė drama theatre in Telšiai in 2008. Moreover, the study shows the author’s impressions from the play “Žaldokynė” performed at the “Vyšnių festival” in Žagarė in 2010

    The aim of this paper is to analyse political activity in the mass media discourses of states with more democratic and more authoritative regimes respectively, so as to show a clear difference in the context of a formal analysis of mass media content. The current study examines political news on qualitative online media portals in Lithuania, Belarus and Ukraine. Thirty years ago, these states began their independent transition from a closed system to openness/democracy. However, at today’s transition point, only Lithuania is considered a democratic country. In different periods Ukraine has been considered an example of competitive authoritarianism, while Belarus deviated towards complete authoritarianism and dictatorship. All political news items between 2005–2020 (for delfi.lt – since 2007) were collected with the help of the Python program. To measure the indicators, several Python programs were designed. The results of the research confirmed that the intensity of political activity differs in the mass media discourses of states with more democratic (Lithuania, Ukraine) and more authoritative (Belarus) regimes. Furthermore, a clear difference was shown in terms of five indicators, average indicators and the dynamics thereof

    Accumulation of feed waste from a long-term aquaculture practice has resulted in the deterioration of the aquaculture environment. Floating net aquaculture engineering of tiger grouper (Epinephelus fuscoguttatus Forsskål, 1775) on Bacillus subtilis supplementation in the diet is one of the solutions to overcome the deterioration of the aquaculture environment caused by the accumulation of dieting waste. The purpose of the research was to study the effects of B. subtilis supplementation in the diet on protein digestibility, the efficiency of diet utilization, growth, and activities of digesting enzymes of E. fuscoguttatus. The sampled fish has an average weight of 4.24 g ± 0.023 g per fish. Diet used in the study contained 45 % protein with the supplementation of various amounts of B. subtilis varying in (0, 2.5, 5, 7.5, 10, and 12.5) % per kg of diet as A, B, C, D, E, and F treatment, respectively. The results show that B. subtilis supplementation in the diet significantly affected on protein digestibility (ADCP), the efficiency of diet utilization (EFU), feed conversion ratio (FCR), the protein efficiency ratio (PER), relative growth rate (RGR), survival rate (SR) and activities of digesting enzymes of E. fuscoguttatus. In conclusion, the optimum amounts of B. subtilis in the diet on ADCP, EFU, FCR, PER, RGR, and SR were at (7.34, 7.36, 7.18, 7.5, 7.48, and 7.5) % per kg of diet, respectively

    No full text
    To commemorate the 250th anniversary of his birth, the year 2021 was declared the year of Jurgis Ambroziejus Pabrėža (1771–1849). J.A. Pabrėža was a priest, Franciscan, scientist, botanist, educator, participant of Lithuanian Cultural Movement, Samogitian writer and creator of scientific terms, bibliophile as well as professional preacher. Fr. J.A. Pabrėža prepared his sermons with great responsibility, choosing a topic relevant to the time and place and taking into account the mentality of his listeners. He himself compiled his sermons and divided them by topic. The subject of this article is mariology in Fr. J.A. Pabrėža’s sermon collection entitled “Sermons on Various Matters”. J.A. Pabrėža’s sermons clearly reveal marionism in addition to the necessary christocentrism. By focusing on the proclamation of salvation through Jesus Christ and within Jesus Christ, the preacher associates this proclamation with a special emphasis on the role of the Blessed Virgin Mary in the history of salvation. Without Holy Mary, there would be no Jesus Christ, and thus there is an interconnection between the worship of Jesus Christ and the reverence for the Blessed Virgin Mary
