Small-Scale Dosimetry for the Testis: Applications in Nuclear Medicine Diagnostics and Therapy

Popular Abstract in English 111-Indium is a radioactive isotope that can be chemically linked to different molecules. When this compound is given to patients is distributed heterogeneously within the structures that build up the testicle. Different parts of the so-called germ cells are sensitive to radiation in different ways. Therefore, if a radioisotope that send out electrons with low energies It is well known that the testicles are among the most radiosensitive tissue, and constitute an important critical target for both external and internal radiation during diagnostic and therapeutic use of radionuclides. In systemic radionuclide therapy where very high activities are administered, the testis may become a dose-limiting organ; often with a complex, non-uniform activity distribution an

In-situ vehicular antenna integration and design aspects for vehicle-to-vehicle communications

Vehicle-to-vehicle (V2V) communications aim to enhance driver safety and traffic efficiency by using the recently designated frequency bands in the 5.9 GHz range in Europe. Due to the time-frequency selective fading behavior of the vehicular communication channel, multi-antenna techniques can provide enhanced link conditions by means of diversity processing. This paper highlights the integration o

Utilization of terrestrially derived dissolved organic nitrogen by aquatic bacteria

I investigated the bacterial utilization of terrestrially derived dissolved organic nitrogen (DON) in aquatic ecosystems, and assessed the potential role of river-born DON in marine eutrophication. To determine the bioavailability of DON, I developed a bioassay employing N-limited bacterial regrowth cultures, which were calibrated with additions of inorganic nitrogen. I found that between 2 and 72

Sustainable Development Through Global Learning and Teaching

Towards sustainability the implementation of Global Learning for Sustainable Development (GLSD) is crucial. A better understanding of how to – from a global didactic angle – establish globally genuine dialogues forming nuanced conceptions of sustainable development (SD) is necessary. Global teaching as well as global learning has to identify the challenges in various contexts for transdisciplinary

Wrap your troubles into dreams

Wrap Your Troubles into Dreams, är ett praktikbaserat forskningsprojekt. Undersökningen berör stadsomvandlingsprocesser i Stockholmsområdet, speglade genom två politiska förhållningssätt gestaltat i staden: genomförandet av det funktionsseparerade Stockholms City (under 1960-talet) och de senaste decenniernas privatisering av stadsrummet. I forskningen har jag utgått från två platser som i motreakWrap Your Troubles into Dreams is a practice-based artistic research project. The study investigates city transformation processes in the Stockholm area, by viewing them through two political attitudes expressed in the city; the introduction of the function-separated Stockholm City area (during the 1960s) and the privatisation of urban space during the last few decades. I have based my research on

Structuring uncertainty: sponsoring innovation and creativity

Dynamic and complex decision-making environments may involve high levels of uncertainty. Such uncertainty may lead to difficulty within decision-making processes. High levels of uncertainty in decision-making occur in a dynamic and complex environment. While decision-making is needed as a response to uncertainty, this may lead to difficulty within decision-making processes. Furthermore, there are
