    Get PDF
    Hypovolemia is represented in the clinical pathology of the dog in a high percentage. It mostly presents an accompanying syndrome in many diseased conditions (vomiting, diarrhea, sequestration, burns, cold burns, ascites periocardiac efusions, and others), while they primarily occur following acule hemorrhagia. Having in mind its diverse etiology, hypovolemia, in addition to a lack of fluids, can also be characterized by various other deficiencies (of electrolytes, proteins, albumins, carbohydrates), which presents an important factor for evaluating the condition of the patient and prescribing the adequate therapy

    This paper is an attempt to analyze particular scenes from the TV series “Složna braća” and “Crni Gruja” and the film “Balcancan” for the purpose of surveying the featured stereotypical representations of former-Yugoslav ethnicities, identifying their roles within the said examples of film and TV discourse, and proving that familiarity with the discursive practices of these particular cultures (discourse communities) is essential for interpreting these artistic discourses (texts) in the manner intended by their authors. Ethnic stereotypes are, therefore, discussed as socio-cultural constructs or myths generated by the discursive practices of a particular culture, as, it is discourses that “bring cultural objects into being by naming them, defining them and delimiting their field of operation” (Stam, Burgoyne and Flitterman-Lewis 2005: 216). They are also viewed as part of a larger structure – a discursive universe comprised of interrelated mythical texts (Johansen and Larsen 2002: 55–56) shaped by former-Yugoslav discourse communities. For this reason, the mentioned texts will be analyzed as sharing the said discursive universe

    summary:The paper applies some properties of the monotonous operators on the complete lattices to problems of the existence and the construction of the solutions to some fuzzy relational equations, inequations, and their systems, taking a complete lattice for the codomain lattice. The existing solutions are extremal - the least or the greatest, thus we prove some extremal problems related to fuzzy sets (in)equations. Also, some properties of upper-continuous lattices are proved and applied to systems of fuzzy sets (in)equations, in a special case of a meet-continuous complete codomain lattice

    Current analytical free-flow speed models consider all rural two-lane highways as the same road type despite their different functional significance in the network. The aim of this paper is to develop a prediction model for free-flow speed as a function of speed limit and road geometric characteristics for different classes of rural two-lane highways. The research was conducted on 50 representative sections of the two rural classes of two-lane highways equipped with automatic traffic counters in Serbia. In order to develop the appropriate models, it was necessary to determine the threshold values of vehicle time headway in the free-flow for both classes of rural two-lane highways, based on the total number of 191,720 vehicles. The obtained results show that there are differences in the threshold values of free-flow time headway for different road classes. Namely, it was determined that the values of free-flow time headway for Class I amounted to 6.3 s, and for Class II to 8.4 s. The free-flow speed prediction model for different road classes showed that speed limit had the highest impact on free-flow speed for Class I and II highways, followed by horizontal curve radius and shoulder width

    Cilj: Ciljevi ovog istraživanja bili su da se ispita povezanost mikro RNK-10b/21/34a sa kliničkim parametrima i odgovorom na radioterapiju kombinovanu sa temozolomidom kod bolesnika sa glioblastomom. Materijal i metode: U istraživanje su bila uključena 43 pacijenta sa glioblastomom lečenih po Stupovom protokolu. Istraživan je nivo ekspresije mikro RNK-10b/21/34a u tri vremenske tačke. Analizirane su demografske karakteristike pacijenata, kliničko-prognostički faktori, akutna toksičnost, preživljavanje bez progresije bolesti (PFS), ukupno preživljavanje (OS) i njihova povezanost sa nivoima ekspresije mikro RNK-10b/21/34a. Rezultati: Medijana PFS kod naših pacijenata bila je 10 meseci, a medijana OS bila je 15 meseci. 51.2% pacijenata je imalo akutnu toksičnost. 77.3% pacijenata je toksičnost imalo nakon 30. frakcije RT. Pacijenti sa toksičnošću pretežno su bili distribuirani u grupi pacijenata koji su imali glioblastom, NOS. Viši nivoi ekspresije miR-10b i miR-21 pretežno su povezani sa većim gradusom toksičnosti. Nivoi ekspresije miR-34a bili su značajno povišeni na 15. i 30. frakciji zračne terapije, u odnosu na početne vrednosti. Tumori manji od 4 cm su imali višu ekspresiju miR-10b i miR-21 u tački pre početka RT sa TMZ. Duži PFS utvrđen je za vrednosti ekspresije iznad medijane za miR-21 i miR-34a. Duži OS imali su pacijenti sa vrednostima ekspresije miR-10b iznad medijane. Zaključak: Ovo istraživanje je pokazalo da se mikro RNK-10b/21/34a menjaju tokom hemio-radioterapije i da su povezane sa akutnom toksičnošću. Ovaj koncept je jedinstven i sugeriše da se dinamične promene poput varijacija nivoa ekspresije mikro RNK, mogu koristiti kao parametri za predikciju radiosenzitivnosti, odgovora na RT i predikciju akutne toksičnosti.Aims: The objectives of this research were to investigate the associations between microRNA-10b/21/34a and clinical parameters and response to radiotherapy combined with a temozolomide in patients with glioblastoma. Methods: This study included 43 patients with glioblastoma, treated according to Stupp’s regimen. The levels of expression of microRNA-10b/21/34a were measured in the three-time points, at a baseline, at 15th and 30th fraction of radiotherapy (RT). Demographic characteristics of patients, clinical-prognostic factors, acute toxicity, progression-free survival (PFS), overall survival (OS), and correlation with the levels of expression microRNA-10b/21/34a were analyzed. Results: The median PFS in our cohort was 10 months, and the median OS was 15 months. 51.2% of patients had acute toxicity. 77.3% of the patients with toxicity had toxicity after 30th fraction of radiotherapy. Patients with toxicity were predominantly distributed in the group glioblastoma, NOS subtype. Higher expression levels of microRNA-10b and microRNA-21 are predominantly associated with a higher grade of toxicity. The expression levels of miR-34a were significantly elevated at the 15th and 30th fraction of RT, in comparison to baseline levels. Patients with tumor size less than 4 cm had higher expression levels of miR-10b and miR-21 at the baseline. The longer PFS was noticed in patients with expression values above the median value of microRNA-21 and microRNA-34a. Patients with microRNA-10b expression values higher than the median had better OS. Conclusions: This research showed microRNA-10b/21/34a change over treatment and that they are associated with acute toxicity. This concept is unique and suggests that dynamic changes such as variations of microRNA expression levels can be used as parameters for radiosensitivity, response to RT, and prediction of acute toxicity

    KAKO SMO PREŽIVJELE POSTKOLONIJALIZAM: Pravo na identitet u dramama fragile! i Nevidljivi Tene Štiviĉić

    U ovome se radu tumače dvije drame suvremene hrvatske autorice Tene Štivičić u kontekstu postkolonijalne kritike i hrvatske drame. Uporište mojega tumačenja drama fragile! i Nevidljivi jesu intertekstualne spone Tene Štivičić i suvremenoga hrvatskog dramskog ženskog pisma koje, kako ću nastojati pokazati, ima dugu povijest progovaranja s margine i o margini. Žensko dramsko pismo kritizira i redefinira „univerzalne“ stavove o pojedincu i društvu, jeziku, povijesti, kulturnoj i estetskoj formi (Lada Čale Feldman). Analizirane drame čine isto, pri čemu je središnje mjesto njihovih zapleta i mojega čitanja problem identiteta i alteriteta, sepstva i drugosti. Identiteti su rezultat uspješne artikulacije ili „ulančavanja“ subjekta u tok diskursa (Stuart Hall). Ulančavanje subjekata u fiktivne i/ili teorijske diskurse generira zaplete imigrantskih drama Tene Štivičić. Londonskim su imigrantima ponuĎena dva diskursa – orijentalizam i balkanizam, dvije artikulacije drugosti. Unatoč nastojanjima da se upišu u neoliberalne mitove o samoostvarenju, njihovo je nepripadanje neiskupljivo. U dramama je, osim rasnih, etničkih i vjerskih razlika, vaţno i rodno nepripadanje tematizirano nasiljem nad ţenama, prostitucijom i objektifikacijom – imigrantkinje su dvostruke autsajderice

    Many fascinating features of coordination chemistry originate from the fact that small changes in metal ion environment can induce big changes in the properties of the compounds. Moreover, most transition-metal (TM) ions with partially filled d-shells can manifest different spin multiplicity in the ground state that is, different spin states. The identity of the ground spin state and the analysis and description of close lying states of different multiplicity is of crucial importance for the understanding of the microscopic origin of the reactivity, electrochemistry and photochemistry in biomolecules, industrial catalysis and in spin crossover compounds. However, elucidating the role and effect of different spin states on the properties of a system, and even determining which spin state occurs naturally, is challenging task both from an experimental and theoretical point-of-view...Mnoge fascinantne osobenosti koordinacione hemije potiču od činjenice da male promene u okruženju centralnog metala mogu izazvati velike promene u svojstvima jedinjenja. Štaviše, većina jona prelaznih metala (TM) sa delimično popunjenim d-orbitalama može manifestovati različit spinski multiplicitet u osnovnom stanju, tj. različita spinska stanja. Identitet osnovnog spinskog stanja i analiza i opis bliskih spinskih stanja različitog multipliciteta su od ključnog značaja za razumevanje mikroskopskog porekla reaktivnosti, elektrohemijskih osobina, fotohemijskog ponašanja biomolekula, industrijske katalize i spin-crossover (SCO) jedinjenja. Međutim, razjašnjavanje uloge i efekta različitih spinskih stanja na osobine sistema, pa čak i samo određivanje osnovnog spinskog stanja je komplikovan zadatak sa eksperimentalne kao i teorijske tačke gledišta..

    Ова докторска теза обухвата истраживачки рад на унапређењу мерења топлотне проводности термоизолационих чврстих материјала у Метролошкој лабораторији за температуру и термофизичке величине (МЛТВ) Института за нуклеарне науке ВИНЧА. Топлотна проводност се, као једна од најзначајнијих термофизичких величина чврстих материјала, мери различитим експерименталним методама. Метода која код слабо проводних материјала може обезбедити резултате са најмањом могућом мерном несигурношћу је метода заштићене топле плоче и она се као референтна користи у свим најзначајнијим националним метролошким лабораторијама у свету. Експериментална поставка којом се примењује ова метода је установљена у Институту ВИНЧА још 60-их година прошлог века и била је функционална до средине 80-их. Топлотна проводност термоизолационих материјала се у том периоду мерила са релативном мерном несигурношћу од 3 % до 10 %. У складу са убрзаним развојем МЛТВ почетком овог века, као и њеним каснијим признавањем као именоване националне лабораторије за термофизичке величине, приступило се ревитализацији експерименталне поставке и унапређењу поступка одређивања топлотне проводности. У оквиру рада на овој дисертацији је унапређена како сложена мерна апаратура кроз моделовање, израду и тестирање нових елемената и система, тако и калибрациони и мерни поступак и начин обраде мерних сигнала. Као резултат широког унапређења, данас се у Институту ВИНЧА топлотна проводност термоизолационих чврстих материјала може мерити са високом тачношћу и прецизношћу, тј. малом релативном мерном несигурношћу која достиже ниво од 2 %. Тим резултатом, који је потврђен преко међународног међулабораторијског поређења извршеног у оквиру Eura-Thermal пројекта, Метролошка лабораторија за температуру и термофизичке величине Института ВИНЧА се сврстала у ред значајних светских лабораторија те врсте.This PhD thesis implies research on improving the thermal conductivity measurement of thermal insulations in the Metrological Laboratory for Temperature and Thermophysical Properties (MLTV) of the Institute of Nuclear Sciences VINČA. Thermal conductivity, as one of the most important thermophysical properties of solid materials, is measured by various experimental methods. A method that may provide results with a lowest possible measurement uncertainty for poorly conductive materials is the guarded hot plate method and it is used as a reference technique in all most important national metrology laboratories in the world. A related experimental setup was established at the Institute VINČA in the 1960s and was functional until the mid-80s. Thermal conductivity of thermal insulation materials was measured in this period with a relative uncertainty of 3 % to 10 %. In accordance with a fast development of MLTV at the beginning of this century, as well as its subsequent recognition as the designated laboratory for thermophysical properties, a revitalization of the experimental setup and an improvement of the corresponding measurement process began. Within the scope of this dissertation, the measurement apparatus was improved through modelling, designing and testing of new elements and systems, as well as through new calibration, measuring and data reduction procedures. As a result of these improvements, today, the Institute VINČA is capable to measure the thermal conductivity of insulation materials with a high accuracy and precision, i.e. with small relative uncertainties down to a level of 2 %. With this result, which was confirmed through an international inter-laboratory comparison performed within the framework of the Eura-Thermal project, the MLTV of the Institute VINČA has been ranked among the world's leading laboratories of this kind

    Među najuglednijim somborskim intelektualcima između dva svetska rata bio je i dr Simon (Šimon) Gutman, jevrejski sveštenik, nadrabin, publicista i prevodilac, čovek visoke kulture i obrazovanja. Rođen je 1886. godine, a za somborskog rabina postavljen je 1925. godine. Njegovo postavljenje osnažilo je međusobne veze i kulturno-prosvetne aktivnosti somborskih Jevreja, kojih je u to vreme u gradu bilo oko 1.200, a prevashodno su negovali mađarski jezik i mađarsko nacionalno osećanje. Rabin Simon Gutman govorio je i hebrejski jezik, a odlično je poznavao mađarski, nemački, srpski i ruski.Among the most respected Sombor intellectuals between the two world wars was Dr Simon (Shimon) Gutman, a Jewish priest, senior rabbi, publicist and translator, a man of high culture and education. He was born in 1886 and was elected rabbi of Sombor in 1925. His appointment strengthened the mutual ties and cultural and educational activities of the Jews of Sombor, who numbered around 1,200 in the town then and primarily nurtured the Hungarian language and national feeling. Rabbi Simon Gutman also spoke Hebrew and knew Hungarian, German, Serbian and Russian excellent.Podaci prema knjigama „Znameniti Somborci“ Stevana Vasiljevića, „Somborski Jevreji“ Milenka Beljanskog i „Somborski sinovi udovice“ Karla Hamedera.Tekst o rabinu Simonu Gutmanu preuzet sa sajta Ravnoplov [https://www.ravnoplov.rs/
