Full textTema doktorske disertacije je analiza ekstremenih temperatura vazduha na području Vojvodine (severni deo Srbije), koja se prostire na površini od 21.506 km2. U analizi su korišćene vremenske serije sa deset meteoroloških stanica za vremenski period od 1951. do 2000. godine. Ukupno je analizirano osam parametara ekstremnih temperatura, i to: srednje maksimalne i minimalne, apsolutne maksimalne i minimalne i dani sa ekstremnim temperaturama (ledeni, mrazni, letnji i tropski). Istovremeno, u istraživanje su uključene i vremenske serije raspona srednjih maksimuma i minimuma, kao i raspon srednjih apsolutnih maksimuma i minimuma. Tokom rada analizirani su godišnji, sezonski i mesečni nizovi prethodno navedenih parametara ekstrema. U cilju dobijanja neophodnih rezultata, korišćeno je više metoda, kao što su: Aleksandersonov test, prosta linearna regresija, t-test, Men-Kendalov test, koeficijent korelacije, klaster analiza, analiza rojeva tačaka, histogram i višestruka linearna regresija. Rezultati homogenosti mesečnih i sezonskih vremenskih serija, koji su dobijeni korišćenjem Aleksandersonovog testa, predstavljaju prve rezultate za prostor Vojvodine i pokazuju da je 26% ispitivanih nizova nehomogeno, od kojih je 11% podešeno, odnosno homogenizovano. Analize parametara ekstremnih temperatura vazduha pokazuju tendencije porasta u poslednjih pedeset godina XX veka. Posmatrajući godišnje nizove, javljaju se pozitivni trendovi kod svih parametara (osim za ledene i mrazne dane, gde su trendovi opadajući), međutim, jedino se za srednje minimalne temperature može potvrditi da imaju signifikantan porast tokom ispitivanog perioda. Istovremeno, zimski i prolećni trendovi imaju najvišu tendenciju porasta, dok su sa druge strane jesenji trendovi generalno opadajući. Analizom raspona maksimalnih i minimalnih temperatura, uvidelo se da maksimalne temperature generalno imaju nešto veći porast od minimalnih, a karakteristike ovakvih fluktuacija delimično su objašnjene korelacionom analizom sa drugim klimatskim elementima, koji mogu imati uticaj na ekstreme. Rezultati su pokazali da visoku korelacionu povezanost (uglavnom preko 0,7), odnosno uticaj na ekstremne temperature imaju insolacija, oblačnost, padavine i relativna vlažnost vazduha. Interesantno je napomenuti, da u većini radova koji analiziraju raspone maksimalnih i minimalnih temperatura u pojedinim regionima, na nivou kontinenta ili globalnom nivou, ukazuju na negativne trendove raspona ekstrema, međutim na prostoru Vojvodine godišnji rasponi imaju blagi pozitivan trend. Korišćenjem višestruke linearne regresije, uočeno je da pokazatelji atmosferske cirkulacije, odnosno NAO i AO indeksi, objašnjavaju prilično visok procenat varijansi srednjih i apsolutnih maksimalnih i minimalnih temperatura, tokom zimskog, prolećnog i letnjeg perioda. Istovremeno, uzrok rapidnijeg trenda porasta ekstrema tokom poslednje dekade XX veka, ukazuje kako na promene u oscilacijama drugih klimatskih elemenata, tako i na promene dominacije, odnosno učestalosti pojave određenih tipova atmosferske cirkulacije. Rezultati u doktorskoj disertaciji pokazuju da devedesete godine predstavljaju najtopliju dekadu na prostoru Vojvodine u okviru ispitivanog perioda, što je najverovatnije povezano i sa visokim pozitivnim vrednostima NAO indeksa tokom iste dekade, koje imaju uticaj na porast zimskih i prolećnih vrednosti ekstremnih temperatura.
This doctoral thesis deals with extreme air temperatures in Vojvodina (northern part of Serbia), which covers the area of 21,506 km2. Data series at ten meteorological stations for the period 1951- 2000 were used in the analysis. The following eight parameters of extreme temperatures were analysed: mean maximum and minimum; absolute maximum and minimum; and extreme temperature days (freezing, frosty, summer and tropical). Concurrently, the temporal series of mean maximum and minimum range were included into the research, as well as the range of mean absolute maximum and minimum. Annual, seasonal and monthly ranges of the aforementioned extreme parameters were included in the analysis. Towards obtaining important results, several methods were employed, such as Alexandersson test, simple linear regression, T-test, Mann-Kendall test, cluster analysis, scatterplot, histogram and multiple linear regressions. The results of homogenous monthly and seasonal temporal series obtained by employing Alexandersson test, being the first of the kind for Vojvodina highlighted that there were 26% non-homogenous, out of which 11% adjusted, i.e. homogenised within the analysed series. The analyses of extreme air temperature parameters trends showed increase in the last fifty years of the 20th century. Observation of annual series indicated positive trends for all parameters (except for freezing and frosty days, when the trends decreased). However, only mean minimal temperatures confirmed significant increase in the analysed period. Concurrently, winter and spring trends showed the highest increase, whereas autumn trend showed general decrease. In the course of the analysis of maximum and minimum temperature ranges, it was perceived that maximum temperatures generally showed higher increase compared to minimum, whereas the fluctuation features were partially explained by correlation analysis with other climatic elements, which might have influenced extremes. The results approved that high correlation coefficient (mainly above 0.7), i.e. the impact on extremes was perceived with insolation, cloudiness, precipitation and relative air humidity. Interestingly enough, most of the papers researching the series of maximum and minimum temperatures in certain regions, either continental or global, indicate negative trends in ranges of extremes. On the other hand, in Vojvodina the annual ranges show a moderately positive trend. The multiple linear regression technique brought to the perception that atmospheric circulation indicators, i.e. NAO and AO indices, explained the distinctly high percentage of variances in mean and absolute maximum and minimum temperatures during winter, spring and summer period. Concurrently, the cause of rapid increase in extremes during the 1990s indicated both the changes in oscillations of other climatic elements and changes in domination, i.e. frequency of certain types of atmospheric circulation. The results obtained for the doctoral dissertation indicated that the 1990s were the warmest decade in Vojvodina for the analysed period. Most probably, it was associated with high positive values of NAO index for the period, which affected winter and spring values of extreme temperatures.

Full textThe ability of insects to adapt to diverse ecological conditions iswell documented; they are the most diverse fauna on earth, with different species occupying arange of terrestrial and aquatic habitats from the tropics to the poles. Understanding the mechanisms by which insects survive such extreme temperatures and retain viability for longperiods in the dormant state is of great interest to many scientific fields. Insects have evolved three main strategies to survive sub-zero temperatures: i) freeze tolerance, ii) freeze avoidance and iii) cryoprotective dehydration. The main biochemical compounds involved in surviving sub-zero temperatures are same for different strategies but their physiological role is different. They include: ice nucleating agents (INAs), cryo/ anhydroprotectants, and antifreeze proteins (AFPs). The aim of this study was to determine molecular adaptations to extreme cold environments, combining physiology, biochemistry and molecular biology pproaches, in thePolar Collembola: Cryptopygus antarcticus and Onychiurus arcticus. Both species are freeze avoiding but employ different strategies for surviving low temperatures. The Antarctic springtail C. antarcticusis capable of rapid cold hardening with a bi-modal distribution of super cooling points (SCP) with high (less cold-hardened) and low (more cold-hardened) groups of animals present even during the growing season in summer. This bimodal distribution has been well documented, but is poorly understood. The Arctic springtail O. arcticusemploys the strategy known as cryoprotective dehydration to survive winter temperatures as low as -25ºC. With this technique, the amount ofavailable water in the body is reduced to almost zero and also there is an accumulation of trehalose, which acts as a cryo/anhydroprotectant. Although cryoprotective dehydration has been described in other insects, the molecular mechanisms behind this phenomenon are poorly understood.A total of 16,379 EST clones were generated for O. arcticus and 1180 for C. antarcticus. This represents the first publicly available sequence data for this two species providing useful data for comparative genomic analysis. The fact that around 60% of the clones for both species showed no sequence similarity to annotated genes in the datasets, suggests a specific pattern of gene expression in these species as adaptation to low temperatures.Two microarrays were constructed to identify genes involved in surviving low temperatures, one for C. antarcticus by printing 672 clones in duplicate and the other for O. arcticus by printing 6912 clones in duplicate. An analysis of those where putative function could be inferred via database homology, in C. antarcticus there was aclear pattern of up-regulation of structural proteins being associated with the cold tolerant group. These structural proteins mainly comprised cuticle proteins and provide support for the recenttheory that summer SCP variation within Collembola species could be a consequence of moulting, with moulting population having lowered SCPs. In O. arcticus EST and microarrayanalysis revealed clones and biochemical pathways associated with cryoprotective dehydration with a particular reference to genes involved in carbohydrate metabolism, aquaporin genes, heat shock proteins, LEA proteins and antioxidant enzymes.

Full textOsnovni cilj ove disertacije je istraživanje uticaja temperature vazduha na sezonalnost mortaliteta stanovništva u Novom Sadu. Odnos između temperature vazduha i mortaliteta stanovništva istraživan je u periodu od 1897. do 2009. godine. Tokom analize, a u cilju boljeg uočavanja sezonalnih promena mortaliteta stanovništva, posmatrana vremenska serija je podeljena na nekoliko perioda. Prvi period se odnosi na kraj 19. i prvu polovinu 20. veka (1897-1952), drugi period obuhvata drugu polovinu 20. veka (1953-1997), a treći period čini 1998-2009. godina.U radu je analiziran uticaj temperature vazduha na mortalitet ukupnog stanovništva, mortalitet stanovništva prema polu i mortalitet stanovništva starog 65 i više godina, a u periodu 1998-2009. godine, u analizu su uključeni i uzroci smrti stanovništva. Posebno je analiziran kardiovaskularni mortalitet i mortalitet stanovništva izazvan respiratornim bolestima, dok su ostali uzroci smrti posmatrani zajedno.Za analizu uticaja temperature vazduha na sezonalnost mortaliteta korišćene su različite statističke metode kao što su korelaciona i regresiona analiza (grafički prikazane na dijagramu rasturanja), t-test, relativni rizik i koeficijent sezonalne varijacije mortaliteta. Kod analize mortaliteta prema polu korišćen je i odnos šansi.Rezultati dobijeni u ovom radu pokazuju da je mortalitet stanovništva u Novom Sadu veći tokom zimskog perioda godine. U periodu 1897-1952. godine nije pronađena statistički značajna povezanost između temperature vazduha i mortaliteta stanovništva, dok je u drugoj polovini 20. veka (1953-1997) i u periodu 1998-2009. godine uočena statistički značajna negativna korelacija između temperature vazduha i mortaliteta stanovništva, a regresiona analiza pokazuje da se sa rastom temperature vazduha mortalitet stanovništva smanjuje. U periodu 1998-2009. godine pronađena je i statistički značajna negativna korelacija između mortaliteta kardiovaskularnih bolesti i temperature vazduha, kao i između mortaliteta respiratornih bolesti i temperature vazduha, dok kod ostalih uzroka smrti nije uočena statistički značajna veza. Kod analize uticaja temperature vazduha na mortalitet stanovništva prema polu nisu uočene velike razlike između muškaraca i žena. Za razliku od mortaliteta ukupnog stanovništva, kod starog stanovništva (65+), kao najugroženije kategorije, statistički značajna negativna korelacija javlja se od početka posmatrane vremenske serije, a regresiona analiza takođe pokazuje da sa rastom temperature vazduha mortalitet starog stanovništva opada.Analiza u radu pokazala je da se uočeni sezonalni obrazac mortaliteta postepeno menja. Razlike između mortaliteta stanovništva u zimskom perodu u odnosu na periode pre i posle zime, se postepeno smanjuju. Ove promene praćene su i promenom prosečne temperature vazduha. Na osnovu dobijenih rezultata može se zaključiti da promene prosečne temperature vazduha utiču na promenu i balans mortaliteta po mesecima u toku godine.
The main aim of this dissertation is to investigate the temperature-related human mortality in Novi Sad, for the period from 1897 until 2009. In order to detect temporal sesonal changes during time, research period was split in three parts. First period is related to the end of 19th century and first half of 20th century (1897-1953), second period covers second half of 20th century (1953-1997) and third period is related to 1998-2009.In this dissertation impact of air temerature on human mortality of total population, than mortality by sex and mortality of old population (population aged 65 and over) is scrutinised. In the period 1998-2009 in analyses and causes of death are included. Three group of cause of death are investigated: cardiovascular disease, respiratory disease and all other causes of death are observed together.Several different statistical methods were used for analysis of impact of air temperature on seasonal variation of human mortality: correlation and regression analysis (presented at scatter diagram), t-test, relative risk and coefficient of seasonal variation of mortality. The odds-ratio was used in the chapter related to mortality by sex.Results for Novi Sad, show that human mortality in higher during winter period. In the period 1897-1952 statistical analysis does not show significant relation between air temperature and human mortality, while in the period of second half of 20th century (1953-1997) and period 1998-2009 statistical analysis indicated strong negative correlation between air temperature and human mortality and according to results of regression analysis increasing of air temperature is related with decreasing mortality. In the period from 1998 to 2009 statistical analysis show significant and negative correlation between cardiovascular mortality and air temperature, as well as mortality from respiratory disease and air temperature. Analysis of relation between other causes of death and air temperature does not show any significant correlation. There is no clear difference between male and female in the temperature-related mortality patterns. The most vulnerable group is population aged 65 and over. From the beginning of the observed period, statistical analysis indicates strong negative correlation between mortality of old population and air temeprature and regression coefficient demonstrate that increasing air temperature is followed with decreasing mortality.Analysis in this thesis shows changes of seasonal pattern of mortality. Differences between mortality in winter and non-winter period (preceding and following period) are decreasing. During the time, this changes are followed by fluctuation of air temperature. According to results presented in this dissertation it can be concluded that changes of air temperature are connected with changes of distribution of mortality by month, during the year.

Full textThe object of this thesis was to characterize microstructure and mechanical propertiesof the unalloyed ADI material (Austempered Ductile Iron). In addition, the influence ofmicrostructure on the ductile to brittle transition temperature (DBTT) by Charpy impacttest in temperature interval from 196 to +100°C has been studied. The all propertiesobtained depend on the morphology of microstructure and the amount of retainedaustenite, i.e. on the austempering parameters. According to the mechanical propertiesand standard requirements (ASTM, ISO and EN) the processing window has beenproposed, also. It was found that DBTT is influenced by amount and stability of retainedaustenite. In upper temperature range (above cca. 25°C) the most influence factor onDBTT is amount of retained austenite, while at the lower temperatures the stability ismore prominent. Stability of high carbon retained austenite at lower temperaturesprevents transformation to martensite and thus the embrittlement of ADI.

Full textEuropean corn borer, Ostrinia nubilalisHb, is insect species of the temperate zone that survives low winter temperatures as a diapausing larva. Diapausing larvae are cold hardy and tolerate the formation of extracellular ice crystals.The aim of this thesis was to investigate the cellular and molecular basis of O. nubilalis cold hardiness.Thus, our research was focused on the non-diapausing (ND) as well as the diapausing (D) larvae that were exposed to low temperatures during different diapausal phases. Body water management, content of polyols and sugars as well as metabolomic NMR profiles, were assessed. Because of the possible role of the antioxidant defence system (ADS) in insects’ cold hardiness, antioxidant enzymes activity as well as the content of H2O2 and melanin was measured.Results showed that the exposure of diapausing larvae to low temperatures provokes exchanges of osmotically active (OA) body water between hemolymph and fat body. With low temperatures, OA water was decreased in hemolymph, increased in fat body while the content of osmotically inactive (OI) water was constant.The level of glycerol was higher in diapausing compared to non-diapausing larvae, and showed 2-fold increase with the exposure to low temperatures in mid-diapause. This confirmed that glycerol is O.nubilalismajor cryoprotectant in mid-diapause cold hardiness. On the other hand, at the end of the diapause, the content of trehalose, glucose and fructose, except the glycerol, was substantially increased.NMR metabolic profiling confirmed the importance of glycerol in diapausal cold hardiness as well as implied the importance of alanine and proline. In addition to this, putrescine, a well-know stress marker, were detected in ND and D larvae at 5oC suggesting that its metabolites, namely sperimine and spermidine, can have potential role in diapause.The ADS response to low temperatures differs during diapause timescale. In mid-diapause, exposure of larvae to -3oC, but not -16oC, resulted in the elevation of H2O2 concentration and melanin radical signal. On the other hand, the activity of catalase and CuZnSOD, but not of MnSOD, was decreased. Since the mitochondrial MnSOD is the main source of H2O2, this enzyme probably regulates the intracellular level hydrogen peroxide. Melanin probably serves as a defence mechanism against oxidative stress while it reduces the level of intracellular H2O2. Temperature of -3oC is probably the ‘trigger temperature’ for mechanism in adaptation of larvae O.nubilalisto cold. There were no changes detected in ADS during exposure to cold in the end of diapausing period.The results of this thesis suggested that the O. nubilalis diapause is rather dynamic state divided into different phases and that the cold hardiness is highly regulated and in accordance with the current metabolic demands of each diapausal phase.

Full textHur data bör representeras visuellt på ett intuitivt och effektivt sätt undersöks i det vetenskapliga fältet om visualiseringar. Vidare är det utmanande hur geografiska tidsserier ska visualiserar. Utmaningen består i hur en enda visualiserings vy ska skapas som både kan ge en överblick över data och detaljer om specifika data punkter. Anledning till att detta är utmanande är att med fler data dimensioner blir även de möjliga visuella kodnings möjligheterna flera. Därför består utmaningen i hur olika visuella kodningssätt och vyer ska kombineras i en enda vy effektivt. För att designa en effektiv vy undersöktes olika designriktlinjer kopplade till effektivitet. Dessa riktlinjer användes sedan för att designa om en existerande geografisk tidsserie visualisering in en iterativ designprocess. Data som visualiserades var historiska lufttemperaturmätningar i Sverige, en datamängd med både geografiska och tidsberoende komponenter. Den skapade alternativa visualiseringen jämfördes med originalet med hänsyn till effektivitet i en användarstudie. Resultaten tyder på att användarna uppfattar den alternativa visualiseringen som mer effektiv än originalet. Men prestations resultatet på fyra uppgifter tyder inte på att den alternativa visualiseringen skulle vara effektivare. Vidare, jämfört med relaterade arbeten är inte den alternative visualiseringen mer effektiv. Sammanfattningsvis är den alternativa visualiseringen svårare att lära sig än originalet, vilken kan påverka användarnas prestation. Men när användarna lärt sig att använda den alternativa visualiseringen, kan den alternativa vara effektivare att använda än originalet. Vidare är designriktlinjerna användbara i en designprocess men, ingen garanti för en effektiv visualisering i detta fall.

Full textTema doktorske disertacije je primena i procena klasifikacionog sistema lokalnih klimatskih zona (LKZ) pomoću automatizovanog modela i bioklimatskih analiza na primeru Novog Sada (Srbija). Razvijeni GIS model se pokazao kao adekvatan za mapiranje i definisanje LKZ u Novom Sadu i njegovoj okolini izdvojivši čak 13 LKZ upotrebom 7 parametara gradske površine. Osim toga, u okviru disertacije je prikazan i razvijen nov model za čišćenje baze podataka. Dobijeni rezultati su ukazali da se najizraženije razlike u srednjoj temperaturi vazduha (Tsr) javljaju između lokalnih klimatskih zona (LKZ) noću tokom toplotnog talasa i iznose do 5,5 °C (LKZ2-A, razlika između urbane zbijene srednjegradnje i guste šume izvan grada). Na godišnjem nivou razlike u Tsr iznose 1,7 °C između grada iprirodne okoline, odnosno 0,7 °C unutar različitih gradskih LKZ. Statističkom analizom srednjih maksimalnih i apsolutno maksimalnih temperatura vazduha na godišnjem, sezonskom i mesečnom nivou nisu uočene znatne razlike između LKZ. Učestalost pojave temperaturnih indeksa je ukazala da tzv. „hladni indeksi“ (mrazni dani, ledeni dani) ukazuju na temperaturne specifičnosti LKZ u Novom Sadu, dok to nije evidentno analizom tzv. „toplih indeksa“ (letnji dani, tropski dani), izuzev tropskih noći. Analizom relativne vlažnosti vazduha je uočeno da postoje znatne razlike između izgrađenih i prirodnih LKZ, dok to nije slučaj između izg rađenih LKZ. U Novom Sadu se javlja tzv. „urbano ostrvo suvoće“ noću tokom toplotnog talasa kada je zbijena srednjegradnja (LKZ 2) okarakterisana sa maksimalnim deficitom vlažnosti od oko 33% u odnosu na prirodnu LKZ A izvan grada. Statistička analiza vrednosti izračunatih bioklimatskih indeksa PET i UTCI je ukazala da se LKZ razlikuju u uslovima spoljnjeg termalnog komfora čoveka na godišnjem, sezonskom i mesečnom nivou, kao i tokom toplotnog i hladnog talasa (do maksimalnih 8-9 °C). Takođe su rezultati ukazali da je klasifikacioni sistem LKZ adekvatan za inter-urbanu analizu gradske klime (poređenja između gradova).
The topic of the doctoral dissertation is the application and assessment of the classification system of local climate zones (LCZ) using the automated model and bioclimatic analysis on the example of Novi Sad (Serbia). The developed GIS model proved to be adequate for mapping and defining LCZs in Novi Sad and its surroundings by delineating 13 LCZs using 7 parameters of the city surface. In addition, in the framework of the dissertation, is developed new model for cleaning the database. The obtained results indicated that the most pronounced differences in mean air temperature (Tsr) occur between LCZs at night during a heat wave and are up to 5.5 ° C (LCZ2-A, the difference between urban compact midrise and dense forests). At annual level, the difference in Tsr is 1.7 °C between the city and the natural environment, and 0.7 °C within different city LCZs. Statistical analysis of mean maximum and absolute maximum air temperatures at annual, seasonal and monthly levels did not show significant differences between LCZs. The frequency of occurrence of temperature indexes indicated that the so-called "cold indices" (cold days, ice days) indicate the temperature specificity of LCZs in Novi Sad, while this is not evident from the analysis of so-called "warm indices" (summer days, tropical days), except for tropical nights. By analyzing the relative humidity of the air it was noticed that there are significant differences between the built-up and natural LCZs, while this is not the case between built-up LCZs. In Novi Sad there is recognized so-called "Urban dryness island" at night during a heat wave period when a compact midrise LCZ 2 is characterized with a maximum humidity deficit of about 33% compared to the natural LCZ A outside the city. Statistical analysis of the values of calculated bioclimatic indexes PET and UTCI indicated that LCZs differ in the conditions of the outdoor thermal comfort of population at annual, seasonal and monthly levels as well as during heat and cold waves (up to a maximum of 8-9 ° C differences). The results also indicatedthat the LCZ classification system is adequate for inter-urban analysis of the city climate (comparsions between cities).

Full textPhD dissertation indicates a model of state diagnostics, which due to its research nature, could lead to new scientific knowledge and methods of monitoring the impact of the most important parameters on vehicle reliability, the study of key performance in the field of maintenance of motor vehicles. Its aim is to theoretically and empirically, critically, systematically and in a controlled way define the model of conditions diagnostic and to make the selection of optimal parameters, operating temperature and wear of bearings, all for the purpose of determining the security of functioning of the parts and components of motor vehicles. The research process of a model represents the relationship between the periodicity of testing parameters of the operating mode and cancellation of integral components of motor vehicles. The simulation can predict time for replacement of components before they cancel. The present model is of a universal type because it can be applied to complex systems, regardless of the dimensions of the components of motor vehicles.

Full textIntroduction: Traumatic brain injury (TBI) is a global health problem that affects about 10 million people worldwide annually. Severe traumatic brain injury (STBI) account for 10% of all TBI and has high morbidity and unreliable recovery. Early recognition of systemic factors that affect the treatment outcome can have a significant impact on the timely initiation of therapeutic measures and the reduction of morbidity and mortality. The objective of the research: to identify systemic factors that have a significant impact on the treatment outcome of the STBI patients in the Intensive Care Unit (ICU) during the first day of hospitalization. Methodology: The study was conducted as a retrospective-prospective study that included 115 injured patients with STBI who were hospitalized in the ICU, Emergency Center (EC) of the Clinical Center of Vojvodina (CCV) in the period from 01.01.2014 to 1.10.2017. From the medical documentation, for each participant involved in the research, the following parameters within the first 24 hours after the admission were considered and analyzed: demographic and general characteristics of the participants of importance for research and systemic predictive factors (systolic and mean arterial pressure-SAP / MAP, glycemia, body temperature -TT, pH, partial pressure of oxygen-PaO2 and partial pressure of carbon dioxide-PaCO2) registered at five time points (0h, 6h, 12h,18h, 24h). All of the above data were observed and analyzed as predictors, ie, independent variables in relation to the dependent variable "treatment outcome" defined as the Glasgow Outcome Scale (GOS) after the transfer from the ICU to the Clinic of neurosurgery of the CCV and GOS after discharge from a Clinic of neurosurgery and "treatment course" defined by length of stay in ICU, or the total duration of hospitalization in CCV, as well as the release to the home or the appropriate rehabilitation center. Statistical analysis was performed using the IBM SPSS 23 statistical package. The data are presented in tables and graphs, and the statistical significance was determined at p <0.05. The collected data were processed with adequate statistical methods. Results: Systemic factors that had predictive value for the lethal outcome (GOS 1) in STBI during the first day of ICU stay were the use of vasopressors and glycemia. The use of vasopressors increases the likelihood of fatal outcome 4.7 times (OR= 0,214; 95%CI: 0,096-0,479; p<0,05) and glycemic values > 10 mmol/l increase the likelihood of fatal outcome on admission (OR=0,240, 95%CI: 0,087-0,662; p=0,05) and after 24 hours (OR=0,206, 95%CI: 0,037 – 0,929; p=0,05). With each increase in body temperature for one unit in the observed interval, the probability of a positive outcome increases (OR=2,118, 95%CI: 1,097 – 4,091;p<0,05) and glycemic values in the range 4-8 mmol/l increase the probability of a positive outcome 2.5 times. Systemic factors that predict the treatment outcome of the patients after their discharge from ICU are glycemia and body temperature. The blood sugar on admission in the ICU in the range from 6.9 to 7.4 mmol/l increases the opportunity of a better recovery (GOS 4-5 vs. GOS 2-3). Lower glycemic values at the next time points (6h, 12h, 18h) also increase the opportunity of a better recovery. If the body temperature in the 6th and 12th-hour postadmission is higher than 36.5° C, the greater opportunity for better neurological improvement when the patient is discharged from ICU, or from the Clinic of neurosurgery. Participants who had higher values of body temperature had a longer duration of hospitalization (OR 4.096; 95% CI; 0.709-7.483;p<0,05). The length of the stay in ICU, as well as the release to the home or the appropriate rehabilitation center, was not affected by any observed systemic factor. Conclusion: Systemic predictive flow factors and outcome of treatment factors with STBI use of vasopressors, glycemia and body temperature.

Full textU doktorskoj disertaciji izvedeni su modeli za fotoakustički odziv refleksione i transmisione konfiguracije za optički providne dvoslojne uzorke sa toplotnom memorijom, koji predstavlja generalizaciju do sada korišćenih modela i to u tri pravca: uračunat je uticaj konačne brzine prostiranja toplote kroz oba sloja, generalizovan je model tako da uzme u obzir postojanje zapreminske apsorpcije kroz oba sloja i uračunat je uticaj ćelije minimalne zapremine koja se ponaša kao Helmholcov rezonator. Primenom ovog modela na eksperimentalna merenja pokazano je da se može proširiti frekventni opseg koristan za karakterizaciju i oslikavanje (imidžing) različitih uzoraka čime se povećava tačnost određivanja termoelastičnih i optičkih osobina materijala, a posebno struktura sa niskim stepenom uređenja.
In this dissertation, the models of photoacoustic (PA) response are derived for both reflection and transmission PA setup configurations of two-layered optically transparent samples with thermal memory.

The application this model on the experimental measurements has shown the possibility of the extending the frequency range useful for characterization and imaging of different samples, thus increasing the accuracy of thedetermination of thermoelastic and optical properties of various

The purpose of the research is to activate a temperature sensor method and propose an operation process for analyzing operation process of the Chinese restaurant production. The planning is to set up all scenarios for the operation process of central management system after central kitchen production such as store, cargo handling, transportation, and store storage, etc. All procedures follow international food safety standard Hazard Analysis and Critical Control Points (HACCP) that we set up check point to make sure every hazard check point temperature record is under monitoring immediately. For an example, the handheld temperature sensor is installed into the gravy meat pot on the side of the pot to monitor the temperature. The results are kept recorded for central kitchen temperature management system in central kitchen and store freezer. For steam container, a string type temperature sensor is installed inside the container. For food cool down area, a board type temperature sensor is installed beside the basket. If temperature is under standard, system will inform operators with alarm to execute corrective action. Central Kitchen Freezer temperature sensor management and store freezer are installed that we could keep freezer status monitored continuously. The boundary of freezer was set at 7℃. Once the freezer temperature is higher than 7℃, lasting 5 minutes, system will inform the operator immediately and automatically to check freezer status to avoid any food hazard occurrence. When temperature sensor is over standard for 15 minutes in recording, the system will be alarmed by delivering warning messages to the higher level of supervisors. When temperature sensor management system during the process of refrigeration logistics and transportation, it should be kept under 7°C. It should be with continuous type temperature sensor installed. Once the temperature is over warning line, the car driver will be informed by system to adjust car temperature for right temperature. When food is under reheating in store, food center temperature should be ensured reaching 75°C for store temperature sensor management system. Once the temperature is under warning line, the operator will be informed by system to adjust the temperature. This research helps us to set up the system which is immediate traceability from central kitchen production, cool down, cold store, logistics, to store, etc. via a wireless temperature sensor that we could reach cold chain control continuously by delivering the temperature warning message immediately. We could collect the data of lost temperature record from every phase that helps for food safety risk evaluation and best expiring date.

This thesis present a silicon micromachined probe integrated with three Cu-based resistance temperature detectors, three iridium oxide (IrOx)/AgCl pH meters and a PET flexible board as electric interconnect for heart muscle monitoring. The probe exhibits good linearity 98% at least and sensitivity -52.75mV/pH and 0.0259Ω/°C for pH and temperature sensing, respectively. The probe has been utilized for the pH and temperature detection at different depths of a frozen pig heart defrosting at room temperature for testing its feasibility for heart muscle monitoring application. In the measurement, the change of pH values with time shows the quality of testing pig heart starting with a low pH value resulted by myocardial hypoxia, the increase of pH value caused by the glycogen decomposition and drastically decrease of the pH value due to germs breeding at last. On the other hand, it was found that there is 3°C difference between the outer and inner surface of the pig heart, which is an important factor for a surgeon to considerate the possible side effects like myocardial necrosis on the heart preservation in open heart surgery.

There are three subjects in this dissertation, we illustrate them below: 1. Fabrication of low ordering temperature L10 FePt thin films Polycrystalline Fe52Pt48 alloy thin films were prepared by dc magnetron sputtering on preheated natural-oxidized silicon wafer substrates. The film thickness was varied from 10 to 200 nm. The as-deposited film was encapsulated in a quartz tube and post-annealed in vacuum at various temperatures for 1 hour followed by furnace cooling. Before annealing treatment, the structure of the as-deposited FePt thin films is in fcc FePt phase with ~4 nm grain size. L10 FePt phase with hard magnetic properties began to occur after annealing at 350 oC. FCC FePt phase transform completely into L10 FePt phase after annealing at 400 oC. Therefore, the ordering temperature from as-deposited soft magnetic fcc FePt phase to hard magnetic fct L10 FePt phase could be reduced down to about 350 oC by preheating substrate and furnace cooling treatment. The ordering rate of L10 FePt phase increases with increasing the annealing temperature. The ordering rate is non-existent at 300 oC. However, it is enhanced dramatically when temperature is raised above 300 oC and becomes nearly fully completed at 400 oC. From TEM bright images, it is clear that by lowering the ordering temperature it helps reduce the grain size of L10 FePt thin films. Grain grows from ~6 nm to ~9 nm when the annealing temperature increases from 350 oC to 400 oC. The magnetic properties measurements indicated that the in-plane coercivity of the films increase rapidly as annealing temperature is increased from 300 oC to 400 oC, but decrease when the annealing temperature is higher than 400 oC. The grain growth, in-plane coercivity, ordering rate, and formation of L10 FePt phase are impeded in thinner films. The critical order-disorder transformation in grain size of FePt is about 4.5 nm. L10 FePt phase and hard magnetic properties only occurred when the grain size is larger than 4.5 nm. After annealing at 400 oC, the in-plane coercivity of Fe52Pt48 thin film with film thickness of ~100 nm is 10 kOe, Ms is 580 emu/cm3, and grain size is about 9 nm. Factors responsible for reducing the order-disordering temperature of L10 FePt phase include higher sputtering rates, lower annealing temperature accompanied with a longer annealing treatment, and substrate preheating. Among these three factors, the higher sputtering rate of FePt plays the dominant role to help reduce the ordering temperature. 2. Study of perpendicular anisotropy of L10 FePt thin films FePt/Pt/Cr trilayer thin films with perpendicular magnetic properties were deposited on amorphous Corning 7059 glass substrate and natural-oxidized silicon (100) wafer substrates. Before sputtering, the base pressure of the sputtering chamber is better than 5×10-9 Torr. The perpendicular anisotropy of FePt(001) texture was not discernible right after depositing the FePt magnetic layer on top of the Cr(200) underlayer. The Cr-rich epitaxial barrier will be formed at FePt/Cr interface distorting the epitaxial growth of FePt(001) magnetic layer above the Cr(200) underlayer. After inserting a Pt buffer layer at the FePt/Cr interface, perpendicular magnetic properties with FePt(001) preferred orientation was observed. Squareness of the L10 FePt film was close to 1 when a magnetic field was applied perpendicular to the film plane. Pt buffer layer serves as a good barrier to impede diffusion of Cr into the FePt layer and modulate the lattice misfit between Cr underlayer and FePt magnetic layer. Semi-coherent epitaxial growth was initiated from the Cr (002) underlayer, continued through the Pt buffer layer and extended into the L10 FePt (001) magnetic layer. In this investigation, the ordered FePt phase in FePt/Pt/Cr film was found to show up at 250 oC substrate temperature. As the substrate temperature is increased to 300 oC, perpendicular texture and magnetic properties of L10FePt(001) become firmly established. Thus, the formation temperature of the ordered FePt(001) preferred orientation can be identified as low as ~300 oC. This is an important fact may be proven to be very useful for practical industrial perpendicular recording media application. 3. The effects on inserting a soft stability layer in perpendicular FePt/Pt/Cr trilayer thin films When a FeTaC soft layer was inserted in FePt/Pt/Cr trilayer thin film, the FePt(001) preferred orientation of the FePt/Pt/Cr trilayer thin films become distorted. Both Cr(200) and FePt(001) orientations were enhanced by adding a Si3N4 layer between FeTaC layer and Cr underlayer. FePt(001) texture will be preserved if Fe is used as the soft layer. But, the dominant magnetic properties of the films so prepared were longitudinal. This is due fact that there exists strong exchange coupling between soft and hard magnetic phase and very large shape anisotropy in the film. If a CoCr layer was used instead as the soft layer, the intensity of FePt(001) orientation will be reduced while the that of FePt(111) orientation enhanced. The perpendicular magnetic properties of FePt/Pt/Cr were distorted when CoCr is used as the soft layer. When a Cr intermediate layer was inserted at the interface of Pt/CoCr, the Cr intermediate layer may grow along the CoCr(11-20) texture and obtain the Cr(200) preferred orientation. Thus, depositing FePt/Pt bilayer films on this new Cr intermediate layer will exhibit FePt(001) texture and obtain perpendicular magnetic anisotropy properties again.

part1 The difference between HD-DVD and DVD-R is that the memory capacity of HD-DVD is 3 to 5 times of DVD-R. The increase of recerdting capatity is due to the track width of swaerding spot seduced form 0.74μm of DVD-R to 0.32μm of HD-DVD。Thus, for the same size compact disk, HD-DVD provides more memory tracks. With regards to such a thin the memory track, the laser dye layer plays a very important role to absorb the blue-ray laser with higher energy. The principle of the barning process form the memory data on disc is caused by laser dye to pits and lands when it absorbs laser light and releases heat to melt the substrate or to cause thermal decomposition.The solubility and stability of the dye also should be considered seriously when using these dye in HD-DVD. As a record medium, it should provide at leastten years of shelf live for comsumers. This stady invohes the synthesis of a series of HD-dvd dyes by changing the substitutents of heterocyclic ring and the measurement of UV/VIS abrsorption and thermal analysis of these dyes.foprfally are may abtion the detailed cardidale for application. part2 A thermochromic compounds may change color with the change of temperature. These materials be divided into inorganic and organic kinds of compounds. The color of these compounds may be reversible or irreversible. By control of temperature solvent polarity or pH value of medium the molecular transformation can be achived and resulfed in the change color for these thermochromic dyes.For example Same of the organic dyes and pigments occur molecular tautomerisim. For example fluorine dyes control by temperature, phthalides dyes control by pH value, and some of the phthalides dyes control by solvent polarity. This study deals with the synthesis of nitrilo-phthalides dyes one of the triaryl alkanes with the Function Group of substitutes on the aromatic rings
