Studies of Long-lived Radionuclides in the Environment - with Emphasis on 99Tc, 237Np and Pu Isotopes

Studies of the long-lived anthropogenic radionuclides 99Tc, 237Np, 239Pu and 240Pu were performed in marine and terrestrial areas contaminated by different accidental and controlled releases of radioactive materials. The three main sources discussed in this thesis are nuclear weapons tests, nuclear reprocessing plants and the Chernobyl accident. Results are mainly based on measurements of environm

Endothelial Barrier Dysfunction in Multiple Organ Injury. An Experimental Study in Rats

Popular Abstract in Swedish Multipel organdysfunktion-syndromet (MODS), dvs utveckling av sviktande funktion i ett flertal organsystem inkluderande lunga, lever, magtarmkanal, hjärta, koagulation, hjärna m fl, kan utvecklas vid ett flertal olika tillstånd. MODS kan uppkomma vid primära infektioner i buken typ inflammation och perforation (bristning) av någon del av magtarmkanalen, akut bukspottkörMultiple organ dysfunction syndrome (MODS) is still the leading cause of mortality in the surgical intensive care unit. The effect on among others endothelial barrier permeability, reticuloendothelial function, organ function and protease-antiprotease activities was studied following a variety of challenges, especially over-activation of macrophages induced by intraperitoneal administration of zym

Algebraic Dependence of Commuting Elements in Algebras

The aim of this paper to draw attention to several aspects of the algebraic dependence in algebras. The article starts with discussions of the algebraic dependence problem in commutative algebras. Then the Burchnall-Chaundy construction for proving algebraic dependence and obtaining the corresponding algebraic curves for commuting differential operators in the Heisenberg algebra is reviewed. Next

Global observables and identified hadrons in the phenix experiment at RHIC

The PHENIX experiment is one of the two large experiments at RHIC. It addresses most of the signals suggested from the Quark-Gluon Plasma. This paper focuses on the measurements of global observables and identified hadron spectra and particle ratios from the two first runs with Au+Au collisions at 130A GeV and 200A GeV. The energy density reached in the most central collisions is about 5 GeV/fm(3)

Packing effects in palladium(II) and platinum(II) compounds, X-ray crystallography

Popular Abstract in Swedish Det finns ett starkt samband mellan en förenings struktur och dess egenskaper. En detaljerad tredimensionell bild av en förenings struktur på molekylnivå är därför grundläggande information för att förstå dess reaktivitet, stabilitet och fysikaliska egenskaper. Röntgenkristallografi är ett utmärkt redskap för att ta reda på ett ämnes struktur i en kristall. En kristallsThis thesis focuses on i) the effect of packing on the molecular geometry ii) packing arrangements of neutral Pd(II) and Pt(II) complexes iii) the trans influence in Pt(II) complexes iv) the differences in bonding in corresponding Pd(II) and Pt(II) complexes and v) the geometry of Pd(II) complexes with potential catalytic properties. Detailed three-dimensional structural information at the atomic

Genocide; a background paper

The report is a brief introduction into the field of comparative genocide studies, written for the Swedish giovernment.

Predicting Travel Times in Dense and Highly Varying Road Traffic Networks using STARIMA Models.

As road networks are becoming increasingly utilised, it is increasingly important to be able to accurately predict travel times for disseminating information among road users and to support traffic management decisions and planning. Over the past few years, a new way of making such predictions utilising the space-time autoregressive integrated moving average (STARIMA) model has been introduced. Th

University and Culture: a Phenomenological Analysis of Formal and Informal Discourse on Education and Research at Universities in Sweden and China

I forskningen som presenteras här görs en empirisk undersökning av vetenskap och dess politiska gestaltning, i en analys av vad dessa begrepp betyder i olika sammanhang. Undersökningen är inriktad på en studie av formell och informell diskurs rörande universitet, utbildning och forskning. Den informella diskursen består av 202 skriftliga intervjuer, där elever och personal i båda länderna svarar pIn this research, science and its political appearance are studied through an empirical exploration of their representations in narrative expressions. The field of investigation is allocated to formal and informal discourse on university, education and research in Sweden and China. The analysed expressions were taken from 202 written reports, as students and personnel in both countries answered an
