We investigate whether stellar-mass black holes have to receive natal kicks in order to explain the observed distribution of low-mass X-ray binaries containing black holes within our Galaxy. Such binaries are the product of binary evolution, where the massive primary has exploded forming a stellar-mass black hole, probably after a common envelope phase where the system contracted down to separatio
Summary Data on species' demography are essential to detect changes in population size, identify drivers of population change, motivate conservation plans, or evaluate the effectiveness of management. The Arctic Skua Stercorarius parasiticus is a seabird with a circumpolar distribution, which is listed as Endangered on the International Union for Conservation of Nature (IUCN) European Red List, al
OBJECTIVE: Explore women's subjective perceptions of healing from perineal tears in childbirth, with a particular focus on infection-related symptoms.METHODS: Women enrolled in a randomized-controlled-trial (ClinicalTrials, NCT02863874) were invited to complete a questionnaire at one- and eight-weeks postpartum. Infection-diagnosis was obtained separately through medical records.RESULTS: 1462 wome
Wild bees are declining in many parts of the world, which poses a risk for crop pollination and ecosystem health. Land use and climate change are two of the main drivers of the decline, and understanding the interactive effects of these two drivers and wild bees is very important to be able to develop proper responses and mitigate future negative effects. In this thesis I have investigated the ef
This report describes how the work has been conducted in the project “A National Strategy for Standardisation of Digital Information Management within the BuiltEnvironment” (further on denoted NSS). This report describes the project background, aim, objective, methodology, schedule, organisation, and identified areas and processes that have been the basis for the development of the initial three-y
Anthropogenic activities such as intensification of agriculture, animal husbandry and expansion of cities can negatively impact wildlife through its influence on the availability of high-quality food resources and pathogen transmission. The house sparrow (Passer domesticus), an urban exploiter, is undergoing a population decline. Nutritional constrains and infectious diseases has been highlighted
I slutet av 2014 hade 38 miljoner människor runt om i världen flytt sina hem till följd av krig, konflikt och våld. Att rädda liv och minska lidandet för dessa flyktingar är syftet med humanitärlogistik. Beredskap en nyckelroll i humanitära organisationer eftersom det är ett verktyg för att minska det negativa genomslaget av framtida händelser. En vanlig beredskapsåtgärd är att så kallad för-positAt the end of 2014, 38 million people around the world had fled their homes due to man-made disasters such as war, armed conflict and violence. To save the lives and alleviate the suffering of these refugees and displaced is the purpose of Humanitarian Logistics. Preparedness is of key importance in humanitarian organisations as it is a tool to reduce the impact of coming events. One common prepar
High-quality biosecurity practices are critical to restarting international tourism. Effective market segmentation improves the communication and efficacy of health advice. Travel frequency is an important basis for health-related consumer segmentation, as it is closely related to risk of greater exposure to infectious diseases. Theoretically grounded studies of tourist biosecurity behavior and tr
Background: Cyanobacterial blooms are of increasing concern for drinking water supply. In Sweden, a survey among drinking water producers showed that the sense of urgency was little. At 60% of the Swedish drinking water treatment plants, operators lacked monitoring strategies. To get a picture of the size of the problem the presence of cyanobacterial risk in 108 Swedish lakes was evaluated from 23
This thesis focuses mainly on the co-integration of vertical nanowiren-type InAs and p-type GaSb MOSFETs on Si (Paper I & II), whereMOVPE grown vertical InAs-GaSb heterostructure nanowires areused for realizing monolithically integrated and co-processed all-III-V CMOS.Utilizing a bottom-up approach based on MOVPE grown nanowires enablesdesign flexibilities, such as in-situ doping and heterostr
The corporate accelerator phenomenon is increasing in popularity and is a common vehicle of external innovation for large organizations. But many initiatives fail, and what characterizes the programs that have had longevity, has not been addressed in existing research. This includes their adherence to operating models of corporate accelerators; accelerating strategic fit between startups and the c
The number of devices connected to the Internet grows constantly. This information entity has been labeled the Internet of Things (IoT). One important aspect of this is the industrial applications, sometimes labeled the Industrial Internet of Things (IIoT). Collecting and analyzing the massive amounts of data that industry generates will only become more and more important as technology and the ne
The purpose of this thesis is to analyze the possibilities and challenges of certification for obtaining sustainable tourism. On the basis of the purpose, I have designed two research questions. 1.Which are the possibilities of certification? 2.Which are the challenges of certification? My problem approach is descriptive and my aim with the thesis is to explain “how things are” at a certain time a
This paper presents a statistical combination of searches targeting final states with two top quarks and invisible particles, characterised by the presence of zero, one or two leptons, at least one jet originating from a b-quark and missing transverse momentum. The analyses are searches for phenomena beyond the Standard Model consistent with the direct production of dark matter in pp collisions at
Background: Air pollution, mainly from combustion, is one of the leading global health risk factors. A susceptible group is the more than 200 million people worldwide suffering from chronic obstructive pulmonary disease (COPD). There are few data on lung deposition of airborne particles in patients with COPD and none for combustion particles. Objectives: To determine respiratory tract deposition o
Popular Abstract in Swedish Den arbetsrehabilitering som traditionellt erbjuds personer med psykisk funktionsnedsättning kan beskrivas som en trappa där varje steg består av olika åtgärder för att öka personernas arbetsförmåga. Målet är att personerna successivt skall bli friskare, öka sin funktionsnivå och utveckla fler färdigheter innan de kan ta steget ut till ett konkurrensutsatt arbete. För pIn the light of the limited research on the subject of Individual Placement and Support (IPS) in a Swedish context, this thesis has contributed with knowledge of the effectiveness and experiences of IPS among persons with severe mental illness (SMI) living in Sweden. The thesis has also provided information about the work motivation among those persons with SMI who seek vocational support by IPS.
The use of Reinforcement Learning (RL) to design controllers for safety critical systems is an important research area. On the one hand, RL can function in and adapt to complex and changing environments without requiring a model of the system. On the other hand, in such systems robustness is of high importance, as well as ways to guarantee and certify a level of robustness. This project investigat
In multi-user multiple input multiple output (MU-MIMO), the complexity of the base-station scheduler has increased further compared to single-user multiple input multiple output (SU-MIMO). The scheduler must understand if several users can be spatially multiplexed in the same time-frequency resource. One way to spatially separate users is through beamforming with sufficiently many antennas. In thi
Background As new product development is becoming more important due to higher and more global competition the new product introduction process needs to be efficient in order to launch new products before they become obsolete. Therefore, a more efficient development process with integrated functions is needed. Concurrent engineering claims to be this and has support in much research. However, conc
In the past people sought for information via libraries, travel magazines or were inspired by marketing the travel agency made in order to attract consumers. Before the Internet era one way communication was the right way to follow. Since Internet was developed two ways communication has evolved and people can talk to each other worldwide. The development of the two ways communication has created
