Popular Abstract in Swedish Alla levande organismer har DNA, och eftersom DNA är livsnödvändigt måste det repareras om det blir skadat. Ultraviolett (UV) strålning från solen är en av de vanligaste orsakerna till att DNA skadas. De flesta skador på DNA som orsakas av UV-strålning utgörs av cyklobutan-pyrimidindimerer (CPD) eller (6-4)-fotoprodukter. Dessa skador består av två intilliggande baser sAll living organisms have DNA and since DNA is essential to life it must be repaired when damaged. UV radiation is one of the major DNA damaging agents, which photosynthetic organisms cannot avoid. The major UV-induced DNA lesions are cyclobutane pyrimidine dimers (CPDs) and (6-4) photoproducts (6-4PPs) and the main repair pathways of theses lesions involve photolyases and various excision repair

This report describes a model for the estimation of the time required to evacuate a building, by dividing the evacuation process into three phases: awareness, behaviour and response, and movement. The times required in each of these phases can be estimated separately and the sum then represents the total evacuation time. The time elapsed from the fire breaking out, to the discovery of the fire, is

Popular Abstract in Swedish I vår kropp står ämnesomsättningen för nedbrytning av mat till kemiska ämnen som är nödvändiga för vår energiförsörjning, kroppsuppbyggnad och fortplantning. Varje cell i varje organism tillverkar eller tar upp små molekyler, som de sedan sätter ihop till stora molekyler. Samtidigt som detta sker så bryter cellerna ner molekyler som har blivit tillverkade. Ur detta får There are two fundamentally different ways by which a metabolite can be transferred between enzymes in metabolic pathways. If the two sequential enzymes cannot form a complex with each other, the metabolite must first be released from the producing enzyme to the reaction medium and then be transported to the consuming enzyme, via the reaction medium, by free diffusion. If the two sequential enzyme

Alcohol consumption may be associated with risk of colorectal cancer (CRC), but the epidemiological evidence for an association with specific anatomical subsites, types of alcoholic beverages and current vs. lifetime alcohol intake is inconsistent. Within the European Prospective Investigation into Cancer and Nutrition (EPIC), 478,732 study subjects free of cancer at enrolment between 1992 and 200

Objective: To evaluate the internal consistency of the Hip disability and Osteoarthritis Outcome Score-Physical Function Short-form (HOOS-PS) and the Knee injury and Ostecarthritis Outcome Score-Physical Function Short-form (KOOS-PS) in total hip replacement (THR) and total knee (TKR) replacement. Construct validity and responsiveness were compared to the Western Ontario McMaster Universities' Ost

Hamstring muscles play a major role in knee-joint stabilization after anterior cruciate ligament (ACL) injury. Weakness of the knee extensors after ACL reconstruction with patellar tendon (PT) graft, and in the knee flexors after reconstruction with hamstring tendons (HT) graft has been observed up to 2 years post surgery, but not later. In these studies, isokinetic muscle torque was used. However

The recombinant xylose-utilizing Saccharomyces cerevisiae TMB 3399 was constructed by chromosomal integration of the genes encoding Image-xylose reductase (XR), xylitol dehydrogenase (XDH), and xylulokinase (XK). S. cerevisiae TMB 3399 was subjected to chemical mutagenesis with ethyl methanesulfonate and, after enrichment, 33 mutants were selected for improved growth on Image-xylose and carbon dio

Aim The northern limits of temperate broadleaved species in Fennoscanndia are controlled by their requirements for summer warmth for successful regeneration and growth as well as by the detrimental effects of winter cold on plant tissue. However, occurrences of meteorological conditions with detrimental effects on individual species are rare events rather than a reflection of average conditions. W

PURPOSE: To investigate whether separate physical tests of the lower extremities, that assess movement speed and postural control, were associated with cognitive impairment in older community-dwelling subjects. SUBJECTS AND METHODS: In this population-based, cross-sectional, cohort study, the following items were assessed: walking speed, walking 2 × 15 m, Timed Up and Go (TUG) at self-selected an

Introduction: The aim of this study was to investigate the role of hand bone mineral density (BMD) loss analyzed with digital X-ray radiogrammetry (DXR) in early rheumatoid arthritis (RA) as a predictor for progression of joint damage. Methods: In 379 patients with early RA, baseline and one-year hand BMD was measured with DXR and the hand bone loss (HBL) was analyzed using the smallest detectable

CONTEXT: The prevalence of obesity among adolescents has increased and we lack effective treatments. OBJECTIVE: To determine if gastric bypass is safe and effective for an unselected cohort of adolescents with morbid obesity in specialized health care. DESIGN, SETTING AND PATIENTS: Intervention study for 81 adolescents (13-18 years) with a body mass index (BMI) range 36-69 kg m(-2) undergoing lapa

The goal of inquiry in this essay is to ascertain to what extent the Principle of Compositionality – the thesis that the meaning of a complex expression is determined by the meaning of its parts and its mode of composition – can be justifiably imposed as a constraint on semantic theories, and thereby provide information about what meanings are. Apart from the introduction (Chapter One) and the con

This paper combines epidemiological data on musculoskeletal morbidity in 40 female and 15 male occupational groups (questionnaire data 3720 females, 1241 males, physical examination data 1762 females, 915 males) in order to calculate risk for neck and upper limb disorders in repetitive/constrained vs. varied/mobile work and further to compare prevalence among office, industrial and non-office/non-

Since the demand on ready-to-eat (RTE) and raw, minimally processed products is high and increasing in today´s market, the microbial quality is important. One of these products is RTE salads and salads mixes that are bagged and since it is supposed to be eaten raw without any step to reduce the microbial load, these types of products are considered to be risk foods and that the risk of foodborne o

Popular science summary: Beavers are back in Denmark The beaver Castor fiber is an animal which used to be common in most places all over Europe. The beaver has also been an important resource for humans, where especially the meat, the thick fur and the castoreum, a secretion that was used by humans in perfume, medicines and food, was wanted. Therefore, hunting by humans has been the main reason

Popular science summary: One of the greatest challenges in studying animal behavior is to understand it from the animal’s perspective. We will never know exactly how they look at or think about the world, but we can infer a lot from giving them signals and seeing their responses. In evolutionary biology, we are trying to find out what forces drove change in a specific direction. The “force” or s

It has at times been a debate among media and legislators about the Swedish police officers dis-cretionary application and great room for interpretation when dealing with the Swedish act: the Act (1976:511) on arrest of intoxicated people, etc. (our translation) which in Swedish is short-ened: LOB. It has also been comments on the law's primary care purpose, which is strongly em-phasized in th

Food safety and quality has been an emerging trend on the food market in recent years. In the grain and cereals market focus is shifting from looking at grain as a bulk commodity to look at it as individual kernels. In the pursuit of quality improvement and assurance various methods are emerging attempting to sort grain, all grain, according to quality on a single kernel basis. One such technology

Purpose: In order to study the Galactic Chemical Evolution, elemental abundances are needed. The purpose of this work is to investigate the chemical evolution of the Milky Way by determining several elemental abundances of giants in the local disk. Large surveys are up and coming, and several surveys are already working, and with these, the aim is high quality abundance measurements of several ele
