Effects of support material on the pattern of volatile fatty acid accumulation at overload in anaerobic digestion of semi-solid waste

Anaerobic degradation of a semi-solid waste with a total solids content of 4% particulate matter, much of it insoluble, was investigated in four laboratory-scale reactors. Two of the reactors were equipped with different textile materials for immobilisation of microorganisms, while the other two were used as continuously-stirred-tank reactor references, A constant organic loading rate and hydrauli

Characterisation and differentiation of lactobacilli by lectin typing

Lactobacillus isolates from healthy Estonian and Swedish children were characterised by a lectin typing technique; 56 isolates from six species (L. acidophilus, L. paracasei, L. plantarum, L. fermentum, L. brevis and L. buchneri) were tested. The typing system was based on an agglutination assay with a panel of six commercially available lectins, which,were chosen on the basis of their carbohydrat

Comparison of lung volume reduction surgery and physical training on health status and physiologic outcomes - A randomized controlled clinical trial

Study objectives: In 1996, researchers in Sweden initiated a collaborative randomized study comparing lung volume reduction surgery (LVRS) and physical training with physical training alone. The primary end point was health status; secondary end points included survival and physiologic measurements. Design: After an initial 6-week physical training program, researchers' patients were randomized to

Box-trees and R-trees with near-optimal query time

A box-tree is a bounding-volume hierarchy that uses axis-aligned boxes as bounding volumes. The query complexity of a box-tree with respect to a given type of query is the maximum number of nodes visited when answering such a query. We describe several new algorithms for constructing box-trees with small worst-case query complexity with respect to queries with axis-parallel boxes and with points.

Different types of acid-base changes at birth, fetal heart rate patterns, and infant outcome at 4 years of age

BACKGROUND: To study the relationship between different types of acidemia in umbilical artery blood at birth, fetal heart rate (FHR) patterns during labor, and infant long-term outcome. METHODS: Case-control study of 48 infants with pure high base deficit (base deficit (BD) > or = 12 mmol/L and pCO2 < 8.0 kPa), 51 with mixed acidemia (BD > or = 12 mmol/L and pCO2 > or = 8.0 kPa), born at or after

Core polarization in Ca I and Ca II

The effect of core polarization on binding energies, term splitting, fine structure, and transition probabilities is investigated for the low lying states 4s2S, 3d2D, 4p2P(o) in Ca II and 4s2(1)S, 4s4p1,3P(o) in Ca I. Results from inclusions of core polarization in the form of model potentials are compared with explicit MCHF calculations, and the accuracy of the different approaches is discussed.

Abstract in French La géométrie du tissue urbain a une grande influence sur le microclimat et influence donc le confort thermique extérieur des habitants et, le microclimat urbain influence à son tour indirectement le climat intérieur. Une mauvaise adaption climatique des environnements urbains a souvent pour conséquence l'utilisation d'une climatisation active et ainsi une augmentation de la cons

Jawed polychaetes from the Upper Sylvan Shale (Upper Ordovician), Oklahoma, USA

A jawed polychaete fauna from the upper 30 in of the Upper Ordovician Sylvan Shale (Richmondian, Ash-ill) of Oklahoma is described, based on recovered scolecodonts (polychaete jaws). The fauna includes members of six families: Paulinitidae, Ramphoprionidae, Polychaetaspidae, Atraktoprionidae, Hadoprionidae, and Kalloprionidae. Ten species are identified and one new paulinitid species, Ketmerites (

System weaknesses as contributing causes of accidents in health care

Objectives. Accidents in health care, resulting in injury or death to the patient, are a matter of considerable concern. The aim of this study is to examine whether system weaknesses can contribute to these accidents, and if so, how. Design. Eight consecutive accidents reported to the Health Authority in Sweden were analysed using MTO (Man-Technique-Organization) analysis. Setting. Emergency care

One-year follow-up of cognitive behavioral therapy for phobic postural vertigo

Background Phobic postural vertigo is characterized by dizziness in standing and walking despite normal clinical balance tests. Patients sometimes exhibit anxiety reactions and avoidance behavior to specific stimuli. Different treatments are possible for PPV, including vestibular rehabilitation exercises, pharmacological treatment, and cognitive behavioral therapy. We recently reported significant

Rank-dependent hoarding effort in willow tits (Parus montanus): a test of theoretical predictions

Many birds and mammals store energy as hoarded food supplies. A supply of stored food is beneficial during periods when food is scarce, but building up and managing such a supply also entails costs. The optimal number of caches will be reached when the net benefit is at its maximum. If dominants can steal more stored food from subordinates than the other way around, the optimum will differ between

Temperament, character, and self-esteem in relation to occupational performance in individuals with schizophrenia

Occupational therapy researchers have tried to clarify the links between occupation and statelike characteristics, such as people's experienced health, disability, and quality of life. However, to fully examine the spectrum of potential influences on occupation, trait-like features should also be investigated. This study focused on personality and self-related factors, in terms of temperament, cha
