Popular Abstract in Swedish Hållfastheten hos en balk av konstruktionsvirke är beroende av balkens spännvidd och typ av belastning. En längre balk har en lägre hållfasthet än en kort balk på samma sätt som en balk med konstant moment har lägre hållfasthet än en balk belastad med en punktlast. Orsaken till denna längd- och lastberoende bärförmåga är variationen i hållfasthet längs med en balk. VariThe load carrying capacity of a beam of structural timber is dependent both on the span of the beam and the type of loading. The longer the beam and the more uniform the moment distribution, the lower the load carrying capacity. This phenomenon is due to the variability of material properties within a piece of timber. This variability is, in turn, due to the presence of knots, the slope of grain a

During the last decade there has been an increase in the use of horizontal organizational relationships (HORs) such as strategic alliances, shared services, and outsourcing. Studies accentuate the unstable, fragile nature of HORS and the importance of directing attention to how these arrangements are formed and how and why they change. The aim in this study is to explore control problems of HORs a

Popular Abstract in Swedish Människan lever inte bara själv, utan tillsammans med en mängd bakterier som lever i kroppen. Större delen av dessa lever i tjocktarmen. Dessa organismer är viktiga för vår hälsa. De stimulerar immunförsvaret, sänker pH i tarmen och gör det ogynnsamt för sjukdomsframkallande bakterier att växa till. Bakterierna lever i symbios med oss och med varandra. Förändringar i taThe human gut flora is important for our well-being. The gut bacteria are able to degrade and metabolize complex carbohydrates. Examples of such carbohydrates are β-mannans. β-Mannans consist of a backbone of β-1,4-linked mannose units and are present in e.g. the endosperm of legumes such as guar or carob. The composition of the β-mannan varies with the plant source. Carob and guar β-mannans are s

The ESA space astrometry mission Gala, due for launch in early 2012, will in addition to its huge output of fundamental astrometric and astrophysical data also provide stringent tests of general relativity. In this paper we present an updated analysis of Gaia's capacity to measure the PPN parameter gamma as part of its core astrometric solution. The analysis is based on small-scale astrometric sol

Code-based cryptography is one of the main techniques enabling cryptographic primitives in a post-quantum scenario. In particular, the MDPC scheme is a basic scheme from which many other schemes have been derived. These schemes rely on iterative decoding in the decryption process and thus have a certain small probability p of having a decryption (decoding) error.In this paper we show a very fundam

This paper proposes a novel Doppler penalty kernel used in the computation of multitapers corresponding to the Wigner-Ville distribution. The resulting multitaper spectrogram will approximately fulfil the time-frequency concentration of the Wigner-Ville distribution but also suppress the cross-terms outside a signal dependent Doppler bandwidth, making the penalty kernel appropriate for linear freqThis paper proposes a novel Doppler penalty kernel used in the computation of multitapers corresponding to the Wigner-Ville distribution.

Research shows that young people within ethnic minorities are subjected to police control more often than others, which seems to have a damaging effect on their trust in the police as well as on their wider sense of belonging. What is less often researched is how these young people deal with being over-policed. This article explores narratives of over-policing from those targeted by the police in Research shows that young people within ethnic minorities are subjected to police control more often than others, which seems to have a damaging effect on their trust in the police as well as on their wider sense of belonging.

BACKGROUND/AIM: Diagnostic efficacy, defined as the percentage of rectal suction biopsy (RSB) specimens sufficient enough to determine the absence of ganglia cells in Hirschsprung's disease (HD) diagnosis, has been reported to be low, requiring repeated biopsies. The aim was to explore whether RSB diagnostic efficacy was influenced by the child's weight and to ascertain whether RSB efficacy differ

The anticolonial uprising in 1920 against the British occupation of the provinces of Mosul, Baghdad, and Basra marked an unprecedented escalation in resistance and opposition to the colonial forces. While most narratives of this uprising focus on the more significant events across the lower and middle Euphrates, earlier, unsuccessful episodes of anticolonial resistance also emerged in the Jazirah

Growth conditions on acid soils may be hampered by low nutrient availability and phytotoxic Al (aluminium) concentrations. In this thesis I present my studies on adaptation mechanisms of wild plants to acid soils in the close root environment, the rhizosphere. The studies showed that plants have developed several mechanisms that may work simultaneously to face the complex soil chemistry. A first g

Since the birth of the industrial revolution, there has existed a fear of becoming redundant and unemployed due to technological development. However, this has not been the case, but the last decades have instead seen the surge of income inequality. This has been linked to the growing technology bias towards skilled workers. This paper studies if the interactive effect of technological development

In 2006 a new law in Peru was proposed by the government, compelling civil society organizations to work for the same development goals as the government, which basically meant to account for their funding, and if it was not in line with the goals of the government, organizations would be fined or suspended. I have conducted a minor field study in Peru and investigated the relationship between the

Stair-ascending at maximum ability is required during emergency evacuations to reach a safe refuge from deep underground structures. We hypothesized that an ascent can last maximum 5 min at the individual’s maximum step rate (SR), and oxygen uptake (V˙O2) would not reach a stable state. This study explored stair-ascending endurance and some physiological constraints of performance. Eighteen health

This licentiate thesis focuses on clustered parametric models for estimation of line spectra, when the spectral content of a signal source is assumed to exhibit some form of grouping. Different from previous parametric approaches, which generally require explicit knowledge of the model orders, this thesis exploits sparse modeling, where the orders are implicitly chosen. For line spectra, the non-l

The ongoing climate change is not only a challenge for the environment but also for economic and social development. The continuing rise of consumption and production of natural resources that needs to be preserved is affecting the environment. The urbanization is contributing to a higher demand of commercial buildings and housing, this needs resources like building material which releases carbon

The intention of this thesis is to explore how four self-defined BDSM practitioners describe and understand their practices. Furthermore, I want to explore if their point of view can help us to understand BDSM in other terms than violence and battery. The interviews are semi structured and were done through instant messaging. By using grounded theory method it turned up that the informants describ

Development and optimization of the production of lactic acid bacteria (LAB) and their attendant 'natural' inhibitors as biopreservatives to control undesirable bacteria currently remains a primary focus of several laboratories involved in research concerning food safety and quality. Strategies utilized to study incorporation of biopreservatives into food include either direct use of LAB-strains o

Elevators has for a long period of time been regarded as unsafe to use as a means of egress. This is an opinion that has shifted in the last couple of years as technical solutions has been found to the initial problems when using elevators as an escape route. This report investigates the possibility to replace a staircase with emergency elevators as a means of egress in a buildning. The report als
