Topinambų (Helianthus tuberosus L.) gumbų laikymo sąlygų optimizavimas 2006 m. Lietuvos žemės ūkio universiteto pomologiniame sode išaugintoje topinambų veislėje ‘Swojecki’ tirta laikomų sandėlyje gumbų cheminė sudėtis. Standartiniais metodais žaliavoje nustatyti sausųjų medžiagų, tirpių sausųjų medžiagų, bendrojo, redukuojančių sacharidų bei sacharozės, žalios ląstelienos, žaliųjų proteinų, amino rūgščių kiekiai bei laikymo metu susidarę masės nuostoliai. Tyrimų duomenų vidurkiai bei standartiniai nuokrypiai statistiškai apdoroti programa „Microsoft Excel“. Skirtumų esmingumas (P≤0,05) apskaičiuotas programa „Statistica“. Nustatyta, kad po keturių mėnesių sausųjų medžiagų kiekis topinambų gumbuose, laikytuose polipropileniniuose maišuose, buvo 2,2 karto didesnis nei laikytuose durpėse ar smėlyje. Esminiai didžiausios tirpių sausųjų medžiagų, žalios ląstelienos ir žaliųjų proteinų kiekių netektys (atitinkamai 4,0%, 1,5 % ir 4%.) po keturių laikymo mėnesių nustatyta gumbuose, laikytuose polipropileniniuose maišuose. Esminiai mažiausi bendrųjų sacharidų ir sacharozės kiekiai nustatyti po dviejų mėnesių topinambų gumbuose, nepriklausomai nuo to, kur jie buvo laikyti. Esminiai didžiausi per visą tyrimo laikotarpį redukuojančiųjų sacharidų kiekiai nustatyti polipropileniniuose maišuose, laikytuose topinambų gumbuose. Visu tyrimų laikotarpiu daugiausiai laikomuose topinambų gumbuose, nepriklausomai kur jie buvo laikomi, buvo sukaupta nepakeičiamosios amino rūgšties arginino ir...

Darbe atlikta teorinė paauglių požiūrio į savo kūną ir mitybos įpročių analizė. Iškeltos dvi hipotezės: 1. Dauguma paauglių, norėdamos tapti lieknesnėmis, keičia savo mitybos įpročius, stengiasi sveikai maitintis, didina fizinį aktyvumą. 2. Daugumai normalaus svorio ir kūno sudėjimo merginoms atrodo, kad jų svoris yra per didelis, jos save vertina storesnėmis nei iš tiesų yra, tampa nepatenkintos savo kūno vaizdu.Empirinėje dalyje tiriami paauglių mitybos įpročiai, kūno vaizdas ir fizinis aktyvumas. Taip pat pasitenkinimas savo kūno vaizdu, bei paauglės nurodomas, jos norimas, tobulas kūno vaizdas.Anketinės apklausos metodu buvo atliktas tyrimas, kurio tikslas atskleisti paauglių (mergaičių) požiūrį į savo kūną ir mitybos įpročius. Atlikta statistinė duomenų analizė. Pusiau struktūruotu interviu buvo siekiama išsiaiškinti kaip paauglės vertina ir koks turėtų būti jų tobulas kūno vaizdas. Mergaičių supratimas apie kūno vaizdo estetiką nustatytas paveikslais, naudojant Ališauskaitės (2011) metodika, kur didesnis skirtumas tarp nurodomo kūno vaizdo ir norimo reiškia didesnį nepasitenkinimą savo kūno vaizdu. / The paper displays theoretical analysis of teenage girls’ attitude towards their body and eating habits. There are two hypotheses: 1. Most of the teenage girls change their eating habits, try to eat healthy and do physical activities in order to become fit. 2. Most of the regular weight and body type girls think they weigh too much and asses their self as thicker than they are and become not satisfied with their body. The empirical part studies eating habits, body image and physical activities. Moreover, the satisfaction of one’s body image, given and wanted image of the perfect body is explored.The questionnaire survey was made which aimed to reveal the attitude of teenage girls towards their bodies and eating habits. The statistic data analysis was made. Due to semi-structural interview, the self-assessment of how should a perfect body look like was made. Satisfaction / dissatisfaction of one’s body image (Ališauskaitė, 2011), where the difference between the given body image and the wanted body image shows the greater dissatisfaction of one’s body image.The quantitative part of the research consisted of 403 and the qualitative part of the research consisted of 14 teenage girl participants from various Lithuanian cities and regions.

Good health is a fundamental resource for social and economic development. Non-communicable chronic diseases (NCDs) such as cardiovascular diseases (CVD), cancer, chronic respiratory diseases and diabetes mellitus are reaching epidemic proportions worldwide. Over the last decades NCDs remain the main public health problem in Lithuania also. The leading NCD’s in the Lithuania are CVD and cancer. The key targets of the Health 21 policy for WHO European Region as well as of Lithuanian Health Programme are reduction of morbidity and mortality from CVD, cancer and other NCD’s. The leading strategy to tackle NCDs is control and prevention of risk factors. Common, modifiable risk factors underlie the major NCD’s. Seven risk factors are responsible for the majority of NCD in the European region: high blood pressure, tobacco, alcohol, high cholesterol, being overweight, low intake of fruits and vegetables, and physical inactivity. The lifestyle habits start to develop in childhood. Children and adolescents begin to smoke and use alcohol, adopt unhealthy nutrition habits and sedentary lifestyle. Harmful lifestyle choices lead to children’s overweight, increase of their blood pressure (BP), and metabolic disorders. Many epidemiological studies designed to assess the association between health indices in childhood and adulthood were conducted over the last years. However, the number of longitudinal, cohort studies that would follow people from childhood to middle age and would apply the... [to full text]

Širdies ir kraujagyslių ligos (ŠKL) yra pagrindinė mirties priežastis visoje Europoje ir Lietuvoje. Literatūroje plačiai, tačiau nevienareikšmiai aptarta MS svarba širdies kraujagyslių ligų atsiradimui. Neatsakyta į vieną iš pagrindinių klausimų: kurie MS sudarantys rizikos veiksniai ar jų grupės daugiausia lemia širdies ir kraujagyslių ligų progresavimą. Mes savo darbe įvertinome arterijų funkcinių ir struktūrinių pokyčių bei kairiojo skilvelio miokardo masės indekso kitimų sąsajas su amžiumi, lytimi ir MS; taip pat atsižvelgėme ne tik į MS, bet ir į atskirų širdies bei kraujagyslių rizikos veiksnių nepriklausomą įtaką kardiovaskuliniam pažeidimui. Be to, bandėme nustatyti, koks MS sudarančių atskirų komponentų skaičius gali daugiausia lemti širdies ir kraujagyslių arterijų funkcinius ir struktūriniais kitimus bei kairiojo skilvelio miokardo masės didėjimą. Darbe nustatyta, kad sergantiesiems metaboliniu sindromu nepriklausomai nuo lyties ir amžiaus yra didesnis intimos medijos storis, šlaunies miego arterijų pulsinės bangos greitis ir kairiojo skilvelio miokardo masės indeksas. Didesnis miego arterijoje aterosklerozinių plokštelių skaičius rastas tik moterims su metaboliniu sindromu. Širdies ir kraujagyslių pažeidimų rizika sergantiems metaboliniu sindromu vyrams ir moterims taip pat buvo skirtinga.

Based on some of the data, MS risk factors have different influence on changes of artery structure and function. MS and its components can influence differently the emergence of cardiovascular diseases and advance of complications in men and women. Furthermore, we tried to estimate the number of separate components constituting MS that can have the most significant influence on functional and structural changes in cardiovascular arteries and increase of the left ventricle myocardial mass index. The particularity of changes in different arterial stiffness indicators in patients with MS has not been determined yet in the literature, as well as prognostic value of MS when initiating early disorders in arterial structure and function and left ventricular hypertrophy. The research showed the following results: in subjects with metabolic syndrome irrespectively their gender and age higher intima-media thickness, femoral-carotid arteries pulse wave velocity and left ventricular myocardial mass index were found. However, higher number of atherosclerotic plaques in carotid artery was found only in females. Risk of cardiovascular disorders in males and females with metabolic syndrome is different. Nor in males, neither in females metabolic syndrome had no direct influence on pulse wave velocity, intima-media thickness, hypertrophy of left ventricle... [toliau žr. visą tekstą]

The made-up software let to construct the cylindrical shell with composition in laminate by chosen test (reinforcement’s corner, number of shells), also it offer to simulate a reliability of construction and to optimise it by chosen in statistic parameters. Shell’s parameters can be evaluated like episodic variables, which are modulated with Monte - Carlo method. There is given opportunity to evaluate construction’s reliability: of the supposition that distribution of strain at shell is known, construction can be optimised when we are minimizing mass. If we want to show construction’s distribution of limitary state in dotted chart, we have to model strain’s value in every Monte – Carlo step. It is computed factors, which have influence for shell’s strain in construction’s stability. In such succession of operations is controlled the reliability of model’s evaluation. There are analysed parameters, which have the biggest influence for strain at shell. Studied the minimal shell’s mass fluctuation in dependence with dispersion and also parameter’s, of construction strain, overtop probability.

The suspension of the motor vehicle is one of the most important elements of the flexible mounted and inflexible mounted masses of the vehicle bodywork, and most attention is paid to its exploration and improvement. Analysis of models of equivalent oscillation systems of motor vehicles testifies that the evaluation of motor vehicle oscillations and modelling of its motion modes is still very topical and requires further research. Suspension models of motor vehicles offered in publications regard only the influence of road irregularities, and the modernisation of these models is directed towards the improvement of passengers’ comfort. However not much research has been done on the influence of oscillations of flexible mounted and inflexible mounted masses of the bodyworks of vehicles in the process of braking; also there is not much investigation of the post-accident identification of the vehicle’s movement mode corresponding to the deformations of the suspension and the longitudinal pitch of the bodywork. Research of oscillations in the conditions of emergency braking is primarily important for the work in two practical directions: 1) improvement of calculation methods of motor vehicle’s response to external impact in the conditions of real operation; 2) further improvement of research methods on the road, and analysis of fait accompli road accidents related to oscillations in the emergency braking. Methodology defining the oscillations occurring in the braking may be applied... [to full text]
