Experiences of students with HIV/AIDS in rural, post-conflict Uganda
2015
The roll out of Anti-Retroviral Therapy across Sub-Saharan Africa has given rise to a new generation of adolescents that previously would not have survived into their teen years. The aim of this research is to give voice to these young people, specifically HIV positive students, in the rural, post-conflict area of Katakwi, Uganda. Through the lens of empowerment, which focuses on participation, capacity building, leadership potential, and relationships, this research examines the factors in these students’ lives that contribute to their empowerment, or the absence of these factors that then have the potential to disempower them. It considers the way the students themselves see both the prot…
Measurement of the AtmosphericνeSpectrum with IceCube
2015
We present a measurement of the atmospheric $\nu_e$ spectrum at energies between 0.1 TeV and 100 TeV using data from the first year of the complete IceCube detector. Atmospheric $\nu_e$ originate mainly from the decays of kaons produced in cosmic-ray air showers. This analysis selects 1078 fully contained events in 332 days of livetime, then identifies those consistent with particle showers. A likelihood analysis with improved event selection extends our previous measurement of the conventional $\nu_e$ fluxes to higher energies. The data constrain the conventional $\nu_e$ flux to be $1.3^{+0.4}_{-0.3}$ times a baseline prediction from a Honda's calculation, including the knee of the cosmic-…
Lielvaru (ASV un Ķīnas) sāncensība 21. gadsimtā
2022
Maģistra darba “Lielvaru (ASV un Ķīnas) sāncensība 21. gadsimtā” mērķis ir vairāku lielvaru augšupejas un lejupslīdes teoriju aplūkošana un analīze, saistot tās ar empīriskajiem novērojumiem par šādu sāncensību. Maģistra darbā apskatītās teorijas tiks pretnostatītas ASV un Ķīnas kā lielvaru sāncensībai mūsdienās, tādējādi veicinot izpratni par iespējamo šādas sāncensības izcelsmi un norisi, izrietot no vēsturiskiem gadījumiem, kas saistīti ar lielvaru sāncensību. Darba teorētiskā bāze ietver izklāstu par lielvaru raksturojumu un vairāku citu jēdzienu apskatīšanu, kā arī apskata četras lielvaru sāncensības teorijas. Maģistra darba empīrisko daļu veido lielvaru sāncensības vēsturiskā ietvara …
Dynamic mean absolute error as new measure for assessing forecasting errors
2018
Abstract Accurate wind power forecast is essential for grid integration, system planning, and electricity trading in certain electricity markets. Therefore, analyzing prediction errors is a critical task that allows a comparison of prediction models and the selection of the most suitable model. In this work, the temporal error and absolute magnitude error are simultaneously considered to assess the forecast error. The trade-off between both types of errors is computed, analyzed, and interpreted. Moreover, a new index, the dynamic mean absolute error, DMAE, is defined to measure the prediction accuracy. This index accounts for both error components: temporal and absolute. Real cases of wind …
Upgrading landfill gas using a high pressure water absorption process
2014
Abstract The upgrading of landfill gas (methane 54.2 ± 2.0%, carbon dioxide 42.1 ± 2.4% and nitrogen 3.7 ± 1.2%) was studied with a pilot-scale high pressure water absorption system consisting of absorption, desorption and gas drying units. The gas was upgraded in two phases and with two absorption columns operating in sequence in pressures up to 180 bar, and with initial pressures of 8 and 10 bar. This type of high pressure process, where water is used for increasing the gas pressure, does not need a separate compression unit to produce the gas pressure required by gas vehicles. Product gas with a methane contents ranging from 83.0% to 92.1% was achieved with differing process parameters, …

Training Programs – Training and Development Alternatives for Students
2013
Abstract Training programs have been established as a form of training for adults, being generally used within companies’ personal development alternatives starting from the employees’ performance assessment processes. The current century requires a different way of approaching academic education, starting from the employers’ observation in reference to the lack of the graduates’ key competencies in the hiring process. We intend to demonstrate that it is useful to introduce training programs as an alternative form of education in academia, as well as in the high school environment.
Power and language in a multicultural workplace
2015
Today’s work markets are increasingly shaped by the multilingual reality. The present research offers an intercultural communication perspective on language diversity and power relations at modern work environment. Study investigates how young professionals and their foreign colleagues perceive diversity affecting in their communicative behaviours in culturally heterogeneous workplace. Analysis of data from participants has been conducted through an analysis of open ended self‐report questionnaire in a multinational company where English is used daily as a corporate language. In particular, results of present study indicate that more diverse language skills are attributed to perception of p…
Calculations of high-power production target and beamdump for the GSI future Super-FRS for a fast extraction scheme at the FAIR Facility
2005
A superconducting fragment separator (Super-FRS) is being designed for the production and separation of radioactive isotopes at the future FAIR (Facility for Antiprotons and Ion Research) facility at Darmstadt. This paper discusses various aspects and requirements for the high-power production target that will be used in the Super-FRS experiments. The production target must survive over an extended period of time as it will be used during the course of many experiments. The specific power deposited by the high intensity beam that will be generated at the future FAIR facility will be high enough to destroy the target in most of the cases as a result of a single shot from the new heavy ion sy…
Effects of ultrasound and temperature on copper electro reduction in Deep Eutectic Solvents (DES).
2014
Abstract This paper concerns a preliminary study for a new copper recovery process from ionic solvent. The aim of this work is to study the reduction of copper in Deep Eutectic Solvent (choline chloride–ethylene glycol) and to compare the influence of temperature and the ultrasound effects on kinetic parameters. Solutions were prepared by dissolution of chloride copper salt CuCl 2 (to obtain Copper in oxidation degree II) or CuCl (to obtain Copper in oxidation degree I) and by leaching metallic copper directly in DES. The spectrophotometry UV–visible analysis of the leached solution showed that the copper soluble form obtained is at oxidation degree I (Copper I). Both cyclic voltammetry and…
