OBJECTIVE: To determine if the frequency of alpha 1AT deficiency (PiZ) is increased in patients with abdominal aortic aneurysm (AAA), and, to investigate whether aneurysmal stiffness and other clinical characteristics differ in AAA patients with and without alpha 1AT deficiency. METHODS: We identified alpha 1AT-deficient individuals by a monoclonal-antibody ELISA technique, in 102 consecutive pati

Biotechnological leaching has been proposed as a suitable method for extraction of vanadium from spent catalysts and oil ash. In the biological leaching process, the vanadium(V) can be reduced to vanadium(IV), which is a less toxic and more soluble form of the vanadium. The present investigation showed that Acidithiobacillus ferrooxidans efficiently reduced vanadium(V) in the form of vanadium pent

An on-line microdetector containing amperometric biosensors was used for high temporal resolution (t(90%) approximate to 120 s) monitoring of glucose and ethanol concentrations during small scale fermentations. ne ability of the microdetector to report on the effect of different experimental conditions was tested in fermentation processes carried out at 30 and at 37 degrees C. An increased ethanol

Popular Abstract in Swedish Huvudsyftet med studien har varit att ta fram matematiska samband för dimensionering av processutrustning – dimensionering är ett klassiskt ingenjörsproblem. Korrekt dimensionering är viktig för att utrustningen skall fungera tillfredsställande och dessutom inte resultera i onödiga investerings- och driftskostnader. Den matematiska modell (en uppsättning ekvationer) soA study concerning closure relations pertinent to the design of sorption equipment of absorption heat pumps has been undertaken. Specifically, thermosiphon and vertical falling film arrangements were studied. For the thermosiphon, experimental data on the void fraction, the friction and orifice pressure drops, and the heat transfer coefficient at sub-atmospheric pressures were obtained for vapori

The aim of this study was to describe first-time mothers' views of satisfaction with their first encounter with the nurse, in order to investigate differences between home visits and clinic visits and between high/middle and low socioeconomic classification (SEC). A nation-wide postal questionnaire sent to 800 first-time mothers yielded the data for statistical analysis. Data were collected using

Eighteen groups of guinea pigs were exposed to a simulated impact noise for periods of 1.5-24 h. The peak level was kept constant at 131.5 dB and the repetition rate was varied to give seven different equivalent levels (Leq) between 96 and 117 dB. The auditory thresholds were assessed by electrocochleography after 1 month and compared with those of a control group. Significant damage occurred even

Background: Several countries are discussing new legislation on the ban of smoking in public places, and on the acceptable levels of traffic-related air pollutants. It is therefore useful to estimate the burden of disease associated with indoor and outdoor air pollution. Methods: We have estimated exposure to Environmental Tobacco Smoke (ETS) and to air pollution in never smokers and ex-smokers in

The Excellent University In just a few years, the quest for quality has become a concern of utmost priority in higher education. Universities, faculties, research councils and the National Agency for Higher Education regularly undertake evaluations to find out whether the academic work performed by university institutions is on “highest international level” or not. Ranking-lists are constantly pu

In this study full-scale experiments with two different conventional cooling-coils aimed for display cabinets were performed. Heat transfer and pressure drop on the liquid side for three different single phase secondary refrigerants were studied and compared to predictions by existing correlations. Predominantly, the laminar flow regime was studied. The results show that when predicting the heat t

Memorials wanted: A call for information on memorials in Denmark, where archaeological finds have been discovered.

Electricity has been regarded as a typical example of a general purpose technology and important for the surge both in energy productivity and overall productivity in the American economy in the 1920s. This view was challenged by Nicholas and Moser (2004) based on patent statistics. We argue that other methods are required for studying productivity effects and propose cointegration analyses. We de

Popular Abstract in Swedish Denna avhandling analyserar frågor som berör tillfälliga jobb på den svenska arbetsmarknaden under perioden 1990-1999. Ett viktigt bidrag i avhandlingen är att den stora gruppen tillfälliga jobb delas upp i mindre undergrupper för att ta i beaktande den heterogenitet som finns mellan olika former av tillfälliga jobb. En röd tråd som löper genom hela avhandlingen är fokuThis thesis analyses different aspects of temporary jobs in the Swedish labour market during 1991-1999. Throughout the thesis we put special focus on differences between the genders, and differences between native-born and foreign-born workers. In chapter 1, An Introduction to Temporary Jobs in Sweden, we describe the evolution of different types of temporary jobs in Sweden during the 1990s, we re

Freud´s 1921/1922 essay "Group psychology and the analysis of the Ego" is reviewed in light of Freud´s influence by LeBon, McDougall and Trotter. The cultural climat in post-war Europe and it´s pessimism is also demonstrated as a contributing factor to Freud´s view on groups and massses. Th influence of the essay on subsequent group resaerch is demonstrated and discussed.
