Background: The most common intrarenal cause for acute kidney injury/renal failure is tubular damage. The kidney tubules are arranged as compartments of cellular mosaics to perform their functions, and at rest almost a fifth of the human ATP consumption is allotted to the reabsorption of substances from the filtrate, rendering especially the proximal tubules highly sensitive to oxygen and/or nutri

This dissertation takes its point of departure in two questions about segregation and its implications for architectural research. The first question is whether examining segregation in terms of education is a fruitful tool for analyzing segregation in general. In answering that question, the dissertation describes how educational segregation relates to segregation by income, ethnicity and age. Th

We report our observations of cross-modal interactions between sight and touch using functional magnetic resonance imaging (fMRI). Experiments were devised to show that sight and touch are linked in a cross-modal arrangement, and two separate experiments were done in an MRI scanner. In the first, the subject's right hand was stimulated with a brush; in the second, a video sequence was presented to

The influence of vibration frequency was studied in 110 small-scale compaction tests conducted using a vertically oscillating plate. The underlying soil was dry sand, or sand close to the optimum water content. The results showed that there is a resonant amplification, providing a slightly higher degree of compaction. Frequency has a major influence on soil compaction. An iterative method for calc

Many children with adverse reactions to beta-lactams are labelled as allergic without performing an allergy study to confirm it. In this retrospective study of 10 years, we have detected only 3.3% positive cases. Although International Guidelines recommend a second allergy work-up in patients with a negative study, we found from our results a low profitability of retesting.

We consider the problem of localizing a novel image in a large 3D model. In principle, this is just an instance of camera pose estimation, but the scale introduces some challenging problems. For one, it makes the correspondence problem very difficult and it is likely that there will be a significant rate of outliers to handle. In this paper we use recent theoretical as well as technical advances t

Massive MIMO, also known as very-large MIMO or large-scale antenna systems, is a new technique that potentially can offer large network capacities in multi-user scenarios. With a massive MIMO system, we consider the case where a base station equipped with a large number of antenna elements simultaneously serves multiple single-antenna users in the same time-frequency resource. So far, investigatio

The connection between the tolerances possible to obtain in a machining process and the machining forces and clamping forces in turning of ring-shaped work pieces clamped in conventional chucks with varying jaw numbers has been investigated. The results can be used for adaptive control of the clamping forces in an optimal way so that the work piece does not come loose in the course of machining an

OBJECTIVES To compare the efficacy of tolterodine plus simplified bladder training (BT) with tolterodine alone in patients with an overactive bladder. PATIENTS AND METHODS In a multicentre, single-blind study at 51 Scandinavian centres, 505 patients aged >= 18 years with symptoms of urinary frequency (>= 8 micturitions/24 h) and urgency, with or without urge incontinence, were randomized to ora

Abstract in UndeterminedThis study investigates the determinants of transfer of waste between the affected areas and other municipalities that resulted from the Great East Japan Earthquake. In particular, we investigate to what extent economic factors, but also social factors such as reciprocity and pro-social concerns, affect municipalities’ decision to accept disaster waste. We find some evidenc

Baker's yeast Saccharomyces cerevisiae rapidly converts sugars to ethanol and carbon dioxide at both anaerobic and aerobic conditions. The later phenomenon is called Crabtree effect and has been described in two forms, long-term and short-term effect. We have previously studied under fully controlled aerobic conditions forty yeast species for their central carbon metabolism and the presence of lon

Light neutron-rich even-even nuclei, of which the ground state is oblately deformed, are looked for, examining the Nilsson diagram based on realisticWoods-Saxon potentials. One-particle energies of the Nilsson diagram are calculated by solving the coupled differential equations obtained from the Schrodinger equation in coordinate space with the proper asymptotic behavior for r -> infinity for both

We aim to provide a long-term ecological analysis of land-use and floristic diversity in the transition from traditional to modern land-use management in the time a.d. 1800-2008 in southern Sweden. We use the Regional Estimates of Vegetation Abundance from Large Sites (REVEALS) model to quantify land-cover changes on a regional scale at 20-year intervals, based on the fossil pollen record. Florist

Migration is an important event in many animal life histories, but the degree to which individual animals participate in seasonal migrations often varies within populations. The powerful ecological and evolutionary consequences of such partial migration are now well documented, but the underlying mechanisms are still heavily debated. One potential mechanism of partial migration is between-individu

Retrograde and transganglionic labeling techniques are commonly used to visualize subsets of neurons and sensory afferent projections in the nervous system. These methods commonly require anesthesia and surgical methods. However, some tracers can also be administered systemically in awake animals, thus reducing risks associated with anesthesia and surgery and allowing for labeling of neuronal popu

Epidemiological studies have indicated that chronic obstructive pulmonary disease (COPD) may be associated with an increased incidence of ischaemic cardiac events. The current authors performed a post hoc analysis of the European Respiratory Society's study on Chronic Obstructive Pulmonary Disease (EUROSCOP); a 3-yr, placebo-controlled study of an inhaled corticosteroid budesonide 800 pg-day-1 in

Ultrafiltration has proven to be a useful technology for treating alkaline bleach plant filtrates in sulphite pulp mills. In this investigation the treatment of seven alkaline filtrates from kraft pulp mills were studied. The results include high fluxes and fair, or even good, removal of organic, as well as inorganic, substances. The flux seems to depend on the concentration of the bleach plant fi

In this work we have further characterized the first mitochondrial nucleoside diphosphate kinase (mtNDPK) isolated from plants. The mitochondrial isoform was found to be especially abundant in reproductive and young tissues. Expression of the pea (Pisum sativum L. cv Oregon sugarpod) mtNDPK was not affected by different stress conditions. However, the pea mtNDPK was found to interact with a novel
