Exposure, health effects, immunological markers and biomarkers of susceptibility among Swedish rubber workers

Popular Abstract in Swedish Arbetare i gummiindustrin utsätts för ett stort antal kemikalier med hög giftighet. Tidigare forskning har visat att kemikalierna innebär en fara för hälsan. Gummiarbetarna har tidigare haft en ökad risk att drabbas av olika sjukdomar, t.ex. cancer, hjärtkärlsjukdomar och luftvägsbesvär, jämfört med allmänbefolkningen. Däremot vet man inte exakt vilka ämnen som är farliWorkers in the rubber industry have an increased risk of several diseases, such as airway disease, cancer and probably cardiovascular disease. The exposure is very complex; carbon disulfide (CS2) and polycyclic aromatic hydrocarbons (PAHs) being two of the contaminants. The general aim of this thesis was to find exposure-response relationships usable for risk assessments in the rubber industry. U

Self-assembled aggregates of the carotenoid zeaxanthin: time-resolved study of excited states

In this study, we present a way of controlling the formation of the two types of zeaxanthin aggregates in hydrated ethanol: J-zeaxanthin (head-to-tail aggregate, characteristic absorption band at 530 nm) and H-zeaxanthin (card-pack aggregate, characteristic absorption band at 400 run). To control whether J- or H-zeaxanthin is formed, three parameters are important: (1) pH, that is, the ability to

Flexible Implementation of Model Predictive Control Using Sub-Optimal Solutions

The on-line computational demands of model predictive control (MPC) often prevents its application to processes where fast sampling is necessary. This report presents a strategy for reducing the computational delay resulting from the on-line optimization inherent in many MPC formulations. Recent results have shown that feasibility, rather than optimality, is a prerequisite for stabilizing MPC algo

Mechanisms of phase behaviour and protein partitioning in detergent/polymer aqueous two-phase systems for purification of integral membrane proteins1

Detergent/polymer aqueous two-phase systems are studied as a fast, mild and efficient general separation method for isolation of labile integral membrane proteins. Mechanisms for phase behaviour and protein partitioning of both membrane-bound and hydrophilic proteins have been examined in a large number of detergent/polymer aqueous two-phase systems. Non-ionic detergents such as the Triton series

Management of urinary tract infections in primary care: A repeated 1-week diagnosis-prescribing study in five counties in Sweden in 2000 and 2002

A diagnosis-antibiotic prescribing study was performed in 5 counties in Sweden during 1week in November in the y 2000 and 2002, respectively. As part of the study, the characteristics and clinical management of patients who received diagnoses of urinary tract infections (UTIs) ( n = 1564) in primary care, were analysed. 85% of the visits were by women, and 74% of all consultations were diagnosed a

Ontogenetic and comparative aspects of cerebellar and motor development

During the course of development the motor repertoire of animals and humans alike go through dramatic changes. New motor patterns arise; movements become coordinated, improve in precision and are at the same time continuously calibrated to the changing body dimensions. The cerebellum is critical for movement coordination and adaptation in adults. Also, interfering with cerebellar development durin

Att tänka med träd

Trees are present in the everyday life of most people, as eye-catchers, meeting points, obstacles, etc. Memories of people, events, and actions are also often connected to specific trees. But the same tree may acquire a range of different meanings, depending on personal experience. Adopting an analytical cultural perspective, "Thinking Trees: An Ethnological Study of Narratives About the Meaning o

The rehabilitation and release of injured or ill raptors and owls is widespread. The overall aim of this intervention is the successful reintroduction of the bird into the wild population. Though many injuries are treatable, it is thought that vision-impaired birds have no change of survival and their release is refused. Here we report a case study and give a description of the rehabilitation and
