Clots of 1 ml venous blood formed in glass tubes after 10 min at room temperature were incubated at 37°C with the radiopharmaceutical to be studied. Methods for quality control of the radiopharmaceuticals were compared. Gel chromatography scanning was found to give reliable information. The incorporation into the clot was studied at different pH values and after various time intervals. The highest

One major problem in microwave-induced clinical hyperthermia treatment of superficial tumours is to obtain therapeutic temperatures at the tumour periphery and adequate deep heating when using a single applicator. The use of multiple applicators has therefore been investigated in order to improve the power distribution. Anatomical surface topography often permits the application of two tilted appl
Regional blood flow in rat liver and in inoculated liver tumors was studied before, during and after local hyperthermia treatment at 42.0°C for one hour. Hyperthermia was induced by microwave irradiation of the central liver lobe. The method used for blood flow studies was the clearance of Xenon-133 following portal and intraparenchymal injection. The wash-out curves were analyzed by using a bi-ex
The uptake of97Ru-transferrin (Ru-TF) in tumor and abscess bearing animals was compared with67Ga-citrate (Ga),123I-transferrin (I-TF), and several other plasma proteins. Maximal concentration in tumor of Ru-TF in mice was three times higher than67Ga-citrate (16.80±4.20 vs 5.08±0.58% D/g) although it occurred later (24 h compared with67Ga which reached its maximum 2 h after injection). Whole body a
The blood flow in rat liver was measured with Xe-133. Three techniques for administering the activity to the liver were employed: injection via the portal vein, via the hepatic artery, and directly into the liver parenchyma. Use of intraparenchymal injection of Xe-133 gave 60% higher flow values than by portal or arterial injection techniques. Mean flow index (k1) was for portal injection 0.52, fo
A computerized system for inducing total body hyperthermia by microwave irradiation was tested in rats. The tolerance to hyperthermia at different temperatures and fractions was studied as well as its effect on the growth of transplanted adenocarcinomas in the liver. Survival results indicated that 41.5 degrees C was maximum tolerated temperature both after single and repeated one hour exposures.
According to the UCDP database, roughly 60% of all armed conflicts between 1944 and 2016 have recurred, an issue which has become increasingly incorporated into the framework of United Nations peacekeeping operations. Economist Paul Collier has theorized upon the importance of economic recovery for building sustainable peace, proposing that economic recovery should be the true exit point of UN pea
The thesis investigates discourses on sexual orientation, gender identity, and expression in national addresses performed by Russian President Vladimir Putin since the large-scale invasion of Ukraine in February 2022. It applies an embedded approach of Critical Discourse Analysis and Queer Linguistics to disseminate how such discourses are produced by Putin in the war. The theoretical approach of
Issuing amnesty in the aftermath of violent conflict is a debated topic within Peace and Conflict studies. This thesis intends to contribute to the debate by investigating how the amnesty issued for Kurdish collaborators of the genocide in 1988, influences reconciliation in Iraqi Kurdistan. To achieve this, a content analysis of statements and news articles is employed to analyze the government
In recent years incel (involuntary celibate) perpetuated violence has escalated in the United States. Incels are motivated by deeply rooted misogynistic assumptions, which dehumanises women and promotes degradation and violence towards the group. Despite evidence of escalation research shows that there still are limited perceptions of this violence as a serious threat. Drawing from ideas of femini
The polarizing effect on the relationship between the West and Russia poses poses challenges to the otherwise close ties between right-wing populist parties and Russia. The thesis utilizes political imaginary in conjunction with political narratives to understand the impact of Russia's invasion of Ukraine in 2022 on the political imaginaries of the Sweden Democrats, the National Rally, and the
China and Russia are two influential powers within the international system which have different understandings of the threshold of nuclear use. The purpose and effect of possessing nuclear weapons have been widely researched but have yet to be utilised to analyse the broader effect on security. This thesis intends to understand the relationship between nuclear weapons’ purpose and the role and on
Sweden and Canada are internationally recognised for their contributions to defending human rights and managed to establish a reputation as humanitarian superpowers. However, both countries deal with the aftermath of a long violent past, concerning the dreadful treatment of their respective indigenous populations. In two separate contexts, the First Nations, Métis and Inuit peoples in Canada and t
Abstract The thesis highlights the need for a broader understanding of consociational democracy and its relationship with government immobilism and agonistic peace. Being a mixed study of the period 2006 to 2022, it suggests that the existing theory of consociational democracy, as proposed by Arend Lijphart (1969) overlooks the cyclical nature of these factors in Lebanon. The theis argues that gov
The purpose of this study is to contribute to the understanding of the interconnectedness of organisational identification and employer branding when strong employee identification with corporate social responsibility is prevalent. It is based on a single case study at a Swedish manufacturing company. An abductive research approach allowed us to mutually examine the empirical field and the theory
Cloud computing är en väletablerad affärsmodell för distribution och utveckling av mjukvara. Ett problemområde som ofta nämns i kontexten cloud computing är vendor lock-in, det fenomen som uppstår när en kund upplever sig inlåst till en specifik molnleverantör. Denna studie syftar på att undersöka möjligheten för positiva effekter av vendor lock-in samt hur molnleverantörer upplevs påverka detta.
What is luminal HER2-enriched breast cancer? Breast cancer is the most common cancer amongst women worldwide. While many people think of breast cancer as a singular disease it actually represents an umbrella term covering numerous different types of tumors that are characterized by specific molecular profiles and morphologies, bearing distinct clinical implications. In this light, the adequate su
As important components of the ecological system on earth, microorganisms and plants collectively constitute an assemblage of species called the holobionts. Microorganisms play an important role in the growth, development, and immunity of plants. Microorganisms may act as pathogens of plants, but they may also contribute to plant growth and development as well as help plants to tolerate both bioti
