The impact of metabolic control on the development of rapidly progressive severe retinopathy was studied in 14 young type I insulin-dependent diabetes mellitus (IDDM) patients. Glycosylated hemoglobin (HbAlc) levels 45 months prior to and 12 months after the diagnosis of retinopathy were compared with HbAlc levels in 17 type I IDDM patients with no or minimal background retinopathy, matched for ag

Oxygen consumption, lactate production and tissue contents of ATP, phosphocreatine (PCr) and lactate were measured following readdition of K+ to K+-depleted rat portal veins, in order to study the energy turnover associated with Na+/K+ pumping. During incubation in K+-free medium at 37 degrees C spontaneous contractions disappeared in 10-20 min. Readdition of K+ (5.9 mM) after 40 min K+-free incub

Abstract in UndeterminedIn our modern society peoples attitudes towards animals are inconsistent, to say the least. Behind these heterogeneous attitudes there are several economic and cultural aspects. What possibilities do we have of studying relations between humans and animal, between nature and culture, in the distant past? What are our starting-points? How do we understand realities that diff

Based on the Keldysh formalism, the Boltzmann kinetic equation and the drift-diffusion equation have been derived for studying spin-polarization flow and spin accumulation under effect of the time-dependent Rashba spin-orbit interaction in a semiconductor quantum well. The time-dependent Rashba interaction is provided by time-dependent electric gates of appropriate shapes. Several examples of spin

Objective: To describe-and compare the consumption of total fish (marine foods) and the fish sub-groups - white fish, fatty fish, very fatty fish, fish products and crustacea, in participants from the European Investigation into. Cancer and Nutrition (EPIC) study. Design: Cross-sectional analysis of dietary intake using a computerised standardised 24-hour recall interview. Crude means, means and s

Do two impersonators select the same features of one target speaker? The present study is a comparative survey of two professional impersonators imitating the same target speakers. It is obvious that the impersonator has to capture many different phonetic features of the target speaker and some individual features seem to be more important for a successful voice imitation and for the listener when

With surface X-ray diffraction (SXRD) using a high-pressure reaction chamber we investigated in-situ the oxidation of the Ru(0001) model catalyst under various reaction conditions, starting from a strongly oxidizing environment to reaction conditions typical for CO oxidation. With a mixture Of O-2 and CO (stoichiometry, 2:1) the partial pressure of oxygen has to be increased to 20 mbar to form the

The Swedish welfare state has undergone structural changes in the last few decades, involving various cutback programmes and the decentralization of public service to the municipalities, with a shift from universal to more means-tested rights. Some of the responsibility for service to the very poorest people has been passed on to the family, the market and voluntary organizations. This has been pa

Chloroplasts and mitochondria originated as bacterial symbionts. The larger, host cells acquired genetic information from their prokaryotic guests by lateral gene transfer. The prokaryotically-derived genes of the eukaryotic cell nucleus now function to encode the great majority of chloroplast and mitochondrial proteins, as well as many proteins of the nucleus and cytosol. Genes are copied and mov

The atrial activity of the human heart is normally visible in the electrocardiogram as a P-wave. In patients with intermittent atrial fibrillation, a different P-wave morphology can sometimes be seen, indicating atrial conduction defects. The purpose of this study was to develop a method to discriminate between such P-waves and normal ones. 20 recordings of each type were used in a classification

Popular AbstractDenna avhandling behandlar Alfred Schutz (1899-1959) sociologiska ansats, tidigt av honom själv benämnd som en empirisk vetenskap om duet, med fokus på den teori han utarbetade i syfte att förstärka den förstående sociologin. Baserat på metodologiska resonemang om möjligheten att nå en vetenskaplig kunskap om den meningskontext den andre, duet, handlar utifrån fördjupade Schutz denThis dissertation examines Alfred Schutz's (1899-1959) approach to sociology, which early in his work he called an empirical science of the thou, with an emphasis on the sociological theory he worked out to strengthen interpretive sociology. Based on a methodological understanding about the possibility of being able to achieve scientific knowledge of the other's, the thou's, context within which m

In the present paper an iterative time-reversal algorithm that retrofocuses an acoustic wave field to its controllable part is established. For a fixed temporal support, i.e., transducer excitation time, the algorithm generates an optimal retrofocusing in the least-squares sense. Thus the iterative time-reversal algorithm reduces the temporal support of the excitation from the requirement of negli
