The aim of the present work was to compare natural and chemical gypsums with respect to dehydration rate and to investigate the influence of air temperature, particle size and air humidity. No difference in calcination rate could be observed between natural and FGD-gypsum. However the small samples did not permit tests of setting times or simulation of the mixer behaviour. The calcination rate was

Background. During the past decade, experimental studies have provided convincing evidence that microcirculatory dysfunction plays a pivotal role in the manifestation of tissue injury in ischemia-reperfusion and osteomyocutaneous flap transfer. The study of the mechanisms of injury, however, requires sophisticated experimental in vivo models. With the use of microsurgical techniques, osteomyocutan

Asymmetric vestibular function affects optokinetic after-nystagmus (OKAN) in man, but little is known about the involvement of cervical proprioception in the visual-vestibular interaction reflected as OKAN. We studied the effect of asymmetric cervical proprioception induced by active maximal, or passive 70 degrees sustained horizontal head rotations on OKAN in 16 healthy subjects. We evoked optoki

OBJECTIVE: The study was performed in order to evaluate to what extent hypertension or diabetes mellitus may affect the urinary excretion rate of Tamm-Horsfall protein. MATERIALS AND METHOD: The urinary excretion rates of albumin and Tamm-Horsfall protein, a measure of glomerular and distal tubular function, respectively were measured in patients with essential hypertension (n = 17) and in type 1

Type II collagen (CII) is the main protein component of cartilage and immune recognition of CII plays a critical role for the development of collagen induced arthritis (CIA), a widely used animal model for rheumatoid arthritis (RA). Antigen presentation is an important requirement for the immune response, the more efficient presentation of the antigen the better tolerance will be induced and ther

Invariant NKT cells (iNKT cells) are characterized by a semi-invariant TCR comprising an invariant a-chain paired with beta-chains with limited BV gene usage which are specific for complexes of CD1d and glycolipid Ags like a-galactosylceramide (a-GalCer). iNKT cells can be visualized with a-GalCer-loaded CD1d tetramers, and the binding of mouse CD1d tetramers to mouse as well as to human iNKT cell

An adaptive controller needs supervisoryfunctions in order to function well in an industrial environment.This paper describes these needs, and provides examplesof supervisory functions that presently are used in industrialadaptive controllers. These supervisory functions ensure thatadaptation only is performed when proper excitation is available.Supervisory functions that prohibit adaptation durin

We present a first time-resolved deuterium NMR study on wormlike micelles under shear. For the investigation, a micellar system made of soybean phosphatidylcholine (lecithin), D2O, and cyclohexane was studied in the concentrated regime, in the vicinity of the isotropic/nematic transition but positioned in the equilibrium isotropic phase. The D2O dispersed in the micellar core was used as a probe t

Mechanisms by which self-desiccation occurs, and by which self-desiccation affects different concrete properties, have been explored by researchers contributing their results to this research seminar. By understanding the mechanisms one may also find ways of reducing the negative effects of self-desiccation. Attempts in this direction are presented at the seminar. 18 papers (6 Nordic).

Horizontal movement of liquid containers is a common operation in an industrial packaging machine. During the movement the acceleration of the container induces motion of the liquid within the container, this is referred to as liquid slosh or liquid vibration. If there is too much slosh the liquid might wet the sealing surfaces of the container and even contaminate the machine. There is no measure

In the third generation cellular networks and beyond, a wide variety of different services are/will be provided by the operators. Out of QoS reasons, it is preferable to give higher priority to certain connection types. These include calls carrying delay-sensitive services and already ongoing calls. In this paper, a prioritization method combining bandwidth borrowing and reservation, called BBR, i

This paper investigates the performance of reduced-state trellis-based intersymbol interference equalizers, which are based on the so-called Ungerboeck and Forney observation models. Although the two models are equivalent when an optimum equalizer is employed, their performances differ significantly when using reduced-complexity methods. It is demonstrated that practical equalizers operating on th

Nutrient sensors that can be located directly in the activated sludge processes are gaining in number at wastewater treatment plants. The in situ location of the sensors means that they can be located close to the processes that they aim to control and hence are perfectly suited for automatic process control. Compared to the location of automatic analysers in the effluent from the sedimentation re

Objective. Comparing habitual nutrient intakes in persons with a history of acute myocardial infarction (AMI), and age-matched controls. Design. Cross-sectional study. Subjects. Men and women (525 cases and 1890 matched controls), aged 47-73 years, of the population-based Malmö Diet and Cancer cohort. Methods. Nutrient intakes were assessed by a validated modified diet history method. Body fatn

The experiment was performed on piglets, divided into control and experimental groups The experimental group received orally, from the birth to the 35(th) d of life, 0.4 g/kg b.w./d of L-alanyl-L-glutamine dipeptide (Ala-Gln). One week after weaning the piglets were killed and the small intestine and bones were sampled for histological analyses. Measurements of bone physical and geometric properti
