Denna studie åsyftar att utreda hur saltlösning påverkar vanliga slitlager i kontrast till hur luft samt vatten påverkar slitlager. Slitlagerna representerades av asfalttyperna asfaltbetong, dränerande (ABD11 70/100) vilken är en dränerande beläggning samt asfaltbetong, stenrik (ABS11 70/100) som är en tät beläggning. ABD och ABS användes i experimentet eftersom ABD har en högre hålrumshalt än ABSThis study aims to investigate how salt solution affects typical road wear courses in contrast to how air and water affect road surfaces. The wear layers are represented by the asphalt concrete Porous Asphalt (PA or ABD11 70/100) which is a draining road surface and Stone Mastic Asphalt (SMA or ABS11 70/100) which is a dense road surface. PA and SMA were used as contrasts to use in the experiment

Syftet med detta examensarbete har varit att undersöka hur en förändring av processtemperatur kan påverka processtabilitet och produktion av biogas hos OX2. Anläggningen som drivs och förvaltas av OX2 Bio produktion AB i Helsingborg producerar biogas från främst matavfall från hushåll och från livsmedelsindustrin.

The plant which is operated and administrated by OX2 Bio Produktion AB located in Helsingborg produces biogas from primarily household food waste and waste from food industry. An ideal temperature to produce biogas at the plant is 37 °C but there is a flu

Förstainstansrättens dom i målet Microsoft mot Kommissionen har gett upphov till många konkurrensrättsliga frågor, bl.a. gällande Microsofts tying av Windows Media Player till sitt operativsystem Windows. Denna uppsats för framförallt ett resonemang kring frågan om huruvida de ”traditionella” EG-rättsliga metoder som idag används vid bedömningen av kopplingsförbehåll (tying) är förlegade när dessa

The intention of this master thesis is to model the internal flow of an Alfa Laval course Filter with 20 cm inlet and normal outlet (ALF20), which is an automatic self cleaning filter aimed to rinse the cooling water upstream the inlet of a compact heat exchanger. Along the automatic cleaning process the ALF20 turn into a flushing and a back flushing operation mode. The ALF20 consists of a filter

Every summer the Australian Bogong moth migrates from southern Queensland to the Australian Alps in southern New South Wales. Other migrants such as the monarch butterfly use a time-compensated sun compass. However, the Bogong is nocturnal and only has access to skylight cues such as the moon, polarized light or the Milky Way. Since these are considerably unreliable only being visible short period

The increase of the consumer electronics market the last couple of decades has been one of the main drivers of IC process technology development. The majority of the ICs are used in digital applications, and for these CMOS is the choice of technology. The urge to squeeze more transistors on to a given area has led to shrinking feature sizes. It has resulted in higher transition frequencies and red

The Advanced GAmma Tracking Array (AGATA) is a European project to develop and operate the next generation gamma-ray spectrometer. AGATA is based on the technique of gamma-ray energy tracking in electrically segmented high-purity germanium crystals. This technique requires the accurate determination of the energy, time and position of every interaction as a gamma ray deposits its energy within the

Furthermore, the study explores several ways and means of effectively combating child pornography. Thus, the intention with this essay is to consider various provisions that should be taken in order to achieve a more effective combating of child pornography on the Internet.

The morphology of gas-rich disc galaxies at redshift ∼ 1–3 is dominated by a few massive clumps. The process of formation or assembly of these clumps and their relation to molecular clouds in contemporary spiral galaxies are still unknown. Using simulations of isolated disc galaxies, we study how the structure of the interstellar medium and the stability regime of the discs change when varying the

Elastic fibers containing elastin play an important role in tendon functionality, but the knowledge on presence and function of elastin during tendon healing is limited. The aim of this study was to investigate elastin content and distribution in intact and healing Achilles tendons and to understand how elastin influence the viscoelastic properties of tendons. The right Achilles tendon was complet

Context. Young open clusters (ages of less than 200 Myr) have been observed to exhibit several peculiarities in their chemical compositions. These anomalies include a slightly sub-solar iron content, super-solar abundances of some atomic species (e.g. ionised chromium), and atypical enhancements of [Ba/Fe], with values up to ~0.7 dex. Regarding the behaviour of the other s-process elements like yt

Objectives: To describe the clinical and ultrasound characteristics of adnexal torsion. Methods: This was a retrospective study. From the operative records of the eight participating gynecological ultrasound centers, we identified patients with a surgically confirmed diagnosis of adnexal torsion, defined as surgical evidence of ovarian pedicle, paraovarian cyst and/or Fallopian tube twisted on its

Purpose: To assess the ability of MRI-DTI to evaluate growth plate morphology and activity compared with that of histomorphometry and micro-CT in rabbits. Methods: The hind limbs of female rabbits aged 16, 20, and 24 wk (n = 4 per age group) were studied using a 9.4T MRI scanner with a multi-gradient echo 3D sequence and DTI in 14 directions (b-value = 984 s/mm2). After MRI, the right and left hin

Clouds are essential elements within Earth's atmosphere, posing a challenge for cloud-resolving models in understanding the creation of new cloud ice particles from existing ice and liquid phases. Such ice initiation determines cloud microphysical and radiative properties, influencing cloud phase, precipitation and cloud extent/properties. To address this challenge effectively, it proves beneficia

Aims/hypothesis: Diabetic kidney disease (DKD) is the leading cause of kidney failure and has a substantial genetic component. Our aim was to identify novel genetic factors and genes contributing to DKD by performing meta-analysis of previous genome-wide association studies (GWAS) on DKD and by integrating the results with renal transcriptomics datasets. Methods: We performed GWAS meta-analyses us

Background: Climate change can directly affect human health by varying exposure to non-optimal outdoor temperature. However, evidence on this direct impact at a global scale is limited, mainly due to issues in modelling and projecting complex and highly heterogeneous epidemiological relationships across different populations and climates. Methods: We collected observed daily time series of mean te

The overall purpose of this paper is to contribute to the development of an internal crisis communication perspective. More precisely, we want to discuss and illuminate the need for an emergent, co-worker-oriented perspective on crises. Such a perspective implies a broader view on crises and a need to include change communication as an allied re-search field to crisis communication, and not at lea

Popular Abstract in Swedish Vårt immunförsvar arbetar konstant med att skydda kroppen från olika föremål, t. ex. bakterier, virus, gifter och cancertumörer, som kan orsaka skada eller sjukdom. För att kunna försvara kroppen mot sådana föremål så har immunförsvaret tillgång till flera, oerhört effektiva, vapen. Det viktigt att immunförsvaret känner igen, och endast angriper, skadliga föremål, så atCD40 is a cell surface receptor of pivotal importance that is expressed on several of the cells in the immune system. It is critical for many important events, such as T cell dependent B cell activation, isotype switching, somatic mutation and generation of B cell memory. The central role of CD40 in the immune system makes it an ideal target for antibody based immunotherapy. This led us to charact
