Mixture of Gases with Multi-Temperature: Maxwellian Iteration
No full textIn this paper a hyperbolic model is proposed for mixtures of gases which are neither viscous, nor heat-conducting (Eulerian fluids). It is built upon assumption that each constituent obeys it's own temperature. Restrictions to the structure of the model come out from basic principles of extended thermodynamics, i.e.
Galilean invariance of balance laws and entropy inequality. Hierarchy of hyperbolic subsystems is recognized, with a single-temperature model as principal subsystem and classical Euler's equations as equilibrium subsystem. Finally, in order to relate this model to classical thermodynamics, a Maxwellian iteration is performed in the case of binary mixture, giving rise to a relation between the diference of non-equilibrium temperatures of constituents and classical fields

Punishing wartime sexual violence
No full textWartime sexual violence is a crime that not only leaves a deep physical and psychological trauma on the victim, but also threatens the fabric of society, especially when the ratio of the gravity of the crime and the sanction imposed is distorted. Ultimately, we should underline that real people and real lives lie behind the statistics and legal discussions in this analysis, belonging to a deeply vulnerable category and demonstrating exceptional courage by participating in criminal proceedings; however, the punishment imposed on the perpetrator often failed to contribute to their sense of satisfaction for the suffering suffered. To this end, the analysis and its guidelines, presenting clear criteria by which courts in Bosnia and Herzegovina can be guided when sentencing perpetrators of criminal offence of wartime sexual violence, can serve as an additional tool in the hands of the judiciary in Bosnia and Herzegovina.Full Tex
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Estimation of gestational age by ultrasound and extreme prematurity
No full textAccurate estimation of the gestational age of the fetus is a key assessment made by providers of obstetric care during pregnancy, since decisions concerning management strategies are dependent on this estimate. Thus, the prognosis for preterm infants born at the border of viability is strongly dependent on the accuracy with which gestational age can be determined. The aim of the present theses was to investigate the impact of maternal obesity, different procedures for dating and the different formulae employed in connection with ultrasonographic values on the estimation of gestational age. Furthermore, the incidence of and factors that influence the one-year survival of infants born extremely preterm were explored. Our examination of the data from the EXPRESS study, which cover infants born prior to 27 weeks of gestation, revealed a one-year survival rate of 70%. The chance for survival without any major morbidity increased significantly with advancing gestational age at birth, from 9.8% at 22 weeks to 85% at 26 weeks of gestational age.In accordance with current recommendations in Sweden, estimation of gestational age in 95% of the pregnancies included in the EXRPESS registry was based on measurements of biparietal diameter and femur length by routine ultrasound examination usually performed during mid- trimester. However, the applications of different procedures and dating formulae in other countries make comparisons of rates of neonatal mortality and morbidity both difficult and unreliable. Therefore, we examined estimation of GA based on the last menstrual period (LMP) in this same cohort. The predicted duration of pregnancy based on LMP was in general longer than when assessed by ultrasound, but the rates of survival and morbidity were the same with both approaches. Moreover, we found that despite the fact that the dating formulae developed by Hadlock, Persson and Mul and coworkers are all based on ultrasonographic measurements of biparietal diameter (BPD) and femur length (FL), the estimates of the gestational age that they provide for infants later born extremely preterm differed significantly. Fetuses which are found upon ultrasound examination to be at least 7 days smaller than expected on the basis of the LMP, exhibit an elevated risk for being born small for gestational age (SGA) as well as for stillbirth. In our extensive cohort study based on the Medical Birth Registry, the risk for such a discrepancy was found to be enhanced among obese mothers, increasing linearly with increasing maternal BMI. In this case, all of the dating formulae based on BPD and FL produced similar prediction of SGA.In conclusion, the procedure employed, the choice of ultrasonographic formula applied, and maternal obesity, all influence assessment of gestational age. These findings should be taken into consideration in managing pregnancies that result in preterm infants born on the edge of viability.List of scientific papersI. EXPRESS Group.

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied
