We investigate whether it is possible that viable microbes could have been transported to the Earth from planets in extra-solar systems by means of natural vehicles such as ejecta expelled by comets or asteroid impacts on such planets. The probabilities of close encounters with other solar systems are taken into account as well as the limitations of bacterial survival times inside ejecta in space,
This master thesis aims at deepening the understanding of actors interacting with competitors from the same business field within the tourism sector. Special attention is paid to small and medium sized enterprises. In order to increase the knowledge of the phenomenon the German network forum anders reisen consisting of small and medium sized tour operators has been used as the case to conduct empi
lnvestigation of weak gravel for road construction has been going on at VTI for many years. The overall aim has been to find test methods that correspond with what happens in the road and that are easy to use in any road laboratory. Following methods have been used in this investigation: planetarytype mixer for wear tests, freeze-thaw variation for weathering tests, Californian Bearing Ratio (CBR)
Problem area Alfa Laval is a world leading company in the heat transfers area and have the vision to continue to be that in the future as well. The company has a lot of press lines where the utilization is high and also has started to become old. Prognosis shows that there is an increased demand of heat exchanger in the future. This increased demand is not something that existing lines will manag
One of the defining features of the post-Cold War era is the growth of international migration in all areas of the world, especially in Europe, where the lift of the Iron Curtain created needs and opportunities as far as immigrants are concerned. Although a beneficial process in itself, the growth of migration to Europe was frequently a cause of various forms of conflict, which in the social scien
Background: Prostate-specific membrane antigen positron emission tomography/computed tomography (PSMA PET/CT) enables sensitive detection and staging of prostate cancer, yet its relationship with long-term survival remains unclear. This study aimed to assess whether total lesion volume (TLV) measured on [18F]PSMA-1007 PET/CT predicts overall survival (OS) in prostate cancer patients. Methods: A co
The amyloid precursor protein intracellular domain (AICD) is an intrinsically disordered regulatory segment whose conserved YENPTY motif mediates transient interactions with multiple adaptor and signaling proteins. How sequence perturbations within this motif modulate its accessibility and interaction potential within a disordered ensemble remains poorly understood. Here, we combine small-angle X-
The proline-rich domain (PRD) of the tumor suppressor p53 plays a central role in modulating conformational dynamics and molecular interactions, yet its intrinsic structural behavior remains incompletely understood. Here, we combine extensive all-atom molecular dynamics simulations with biophysical validation to characterize the conformational ensemble of the p53 PRD. The domain behaves as an intr
Retrospective, propensity-score-adjusted (PSA) studies have indicated to practitioners in the field that contrast-induced acute kidney injury (AKI) after contrast-enhanced CT (CECT) is of minor importance or even non-existent. This has led to controversies between clinicians demanding CECT not to miss any diagnoses and radiologists reluctant or even refusing CECT in risky patients. A critical revi
Histatin 5 (Hst5) is a histidine-rich intrinsically disordered protein (IDP) whose biological function arises from a highly heterogeneous conformational ensemble and environmental sensitivity. Unlike structured antimicrobial peptides that rely on persistent secondary motifs, Hst5 remains disordered across a wide range of conditions, enabling continuous adaptation to changes in pH, ionic strength,
The aim of this thesis is to explore the job satisfaction of librarians and try to nuance stereotypes, which the public has and which still exist in massmedia concerning librarians and their work. The study is qualitative and based mainly on semistructured interviews with ten libraries born between 1937s and 1973s of which eight are women and two men. Furthermore, I have divided them into two grou
Sammanfattning Den här uppsatsen behandlar den höga organisationsgraden som vi har i Sverige idag. Huvudsyftet är att ge ett svar på varför organisationsgraden är så hög. Syftet är också att undersöka hur fackföreningsrörelsen kommer att utvecklas i framtiden. Uppsatsen inleds med en redogörelse av faktorer som bidragit till den höga organisationsgrad vi åtnjuter idag. Fackföreningarnas struktur b
The concept of disaster risk reduction has gained more and more attention since the end of the 20th century due to the exponential increased loss of human lives and material losses, without any evidence of increased number of hazardous events. Instead of just managing disastrous events, a greater emphasis has been put on prevention efforts; an understanding of underlying drivers and vulnerabilitie
Second homes, or summer cottages, are widely spread all over Finland. It is estimated that half of the country´s population have an access to one or several second homes. The phenomenon constitutes a remarkable part of how Finns spend their leisure time. Whereas traditional way of life attracts middle aged and retired urban dwellers to return to their roots, increasing number of second home users
Olovligt tillgängliggörande av upphovsrättsligt skyddat material genom fildelning är ett av vår tids mest debatterade ämnen. Teknikens utveckling har gjort det möjligt för enskilda personer att snabbt och kostnadsfritt tillgodogöra sig perfekta kopior av musik och film. Detta resulterar i att kompensation uteblir för upphovsmän och deras rättighetshavare.

In such audits the taxable’s accounting and other materials are compared against the information that has been submi
Polyphenols are a group of compounds that are widely spread in the plant kingdom. These compounds are of great interest for researchers because of their antioxidant properties that are important for both plant life and human health. Sample preparation is a crucial step for the determination of phenolic compounds and their metabolites in biological samples. Methods for isolation and preconcentratio
Cyanobacteria possess unique and exciting features among photosynthetic microorganisms for energy conversion applications. This thesis project focuses on conversion of solar energy into photocurrent generation comparing three different strains of Cyanobacteria, Leptolyngbia sp. from New Zealand (CYN82), Leptolyngbia sp. from Antarctica (CYN65), Chroococcales sp. from Antarctica (CYN67) and one euk
Rätten till familjeåterförening stadgas i såväl EU:s Familjeåterföreningsdirektiv som i den svenska utlänningslagen. Principen om familjens enhet, allas likhet inför lagen och barnets bästa är principer av stor vikt inom både internationell, europeisk och svensk rätt. Trots principer som att familjen ska hållas samman och att det ska göras vad som är möjligt för att återförena splittrade familjer,The right to family reunification is regulated in both the Family Reunification Directive of the European Union and in the Swedish Aliens Act. The principles of the family as a unit, all individuals equality towards the law and the child’s best interests, are principles of high importance in International, European and Swedish law. There are obstacles in the Swedish law preventing many families fr
