Infrared dryers, both gas fired and electrically healed, have become a widespread technology in the paper industry. This work proposes a model for the absorption of thermal radiation in the thickness direction of a paper sheet. The model is based on the multilayer idealization of a paper sheet proposed by Scallan and Porch. In this model, the optical properties of paper are considered as the resul

The purpose of the present study was to establish a rapid and reproducible method for quantification of tissue-infiltrating leukocytes using computerized image analysis. To achieve this, the staining procedure, the image acquisition, and the image analysis method were optimized. Because of the adaptive features of the human eye, computerized image analysis is more sensitive to variations in staini

It is our impression that Gordon Pask’s writings cover fundamentals for large parts of the widely expanding fields of Cybernetics and Systems Theory. Thereby, and by his lecturing activities, he has become a unique figure in maintaining a kind of unity of the field of Cybernetics, well in accord with Wiener’s view (“control and communication in the animal and the machine”; cf[26]). And that, with

Suppose one sets up a sequence of less-and-less valuable objects such that each object in the sequence is only marginally worse than its immediate predecessor. Could one in this way arrive at something that is dramatically inferior to the point of departure? It has been claimed that if there is a radical value difference between the objects at each end of the sequence, then at some point there mus

Previous studies have used recombinant adeno-associated viral (rAAV) vectors to deliver glial cell line-derived neurotrophic factor (GDNF) in the substantia nigra to protect the nigral dopamine (DA) neurons from 6-hydroxydopamine-induced damage. However, no regeneration or functional recovery was observed in these experiments. Here, we have used an rAAV-GDNF vector to express GDNF long-term (6 mon

Vitamin D receptor (VDR) gene polymorphisms have been implicated in susceptibility to tuberculosis (TB), but reports have been inconsistent. We genotyped the VDR single-nucleotide polymorphisms (SNPs) FokI, BsmI, ApaI, and TaqI in 1139 case patients and control subjects and 382 families from The Gambia, Guinea, and Guinea-Bissau. The transmission-disequilibrium test on family data showed a signifi

We prove the existence of the old and metal-rich moving group HR 1614. This is done using the new Hipparcos parallaxes in combination with metallicities derived from Strömgren photometry, supported by dynamical simulations of the evolution of old moving groups in the galactic potential. A new selection criterion for this moving group is presented as well as a new, extended sample of probable membe

Differential photoproduction cross sections are measured for events containing D-*+/- mesons. The data were taken with the H1 detector at the ep collider HERA and correspond to an integrated luminosity of 51.1 pb(-1). The kinematic region covers small photon virtualities Q(2) < 0.01 GeV2 and photon-proton centre-of-mass energies of 171 < W gamma(Cep) < 256 GeV. The details of the heavy quark produ

Conclusion. Lipopolysaccharide (LPS) challenge of the human nose has the capacity to reduce the amount of natural anti-inflammatory proteins, such as uteroglobin. Objectives. Nasal challenge with LPS, an activator of innate immunity, has been shown to increase the amount of pro-inflammatory mediators in nasal lavage fluid. Uteroglobin is a newly described anti-inflammatory mediator that is secrete

Elongation factor P is a universally conserved protein stimulating peptidyltransferase activity during protein synthesis. The factor is sensitive to classical inhibitors of the ribosomal peptidyltransferase activity and is possibly involved in alignment of the substrate tRNAs in the catalytic centre of 70S ribosomes. Elongation factor P from the thermophilic Aquifex aeolicus was overexpressed as a

Microalgae enhance the removal of nutrients, organic contaminants, heavy metals, and pathogens from domestic wastewater and furnish an interesting raw material for the production of high-value chemicals (algae metabolites) or biogas. Photosynthetic oxygen production also reduces the need for external aeration, which is especially advantageous for the treatment of hazardous pollutants that must be

1. The input characteristics and distribution of climbing fibre field potentials evoked by electrical stimulation of various parts of the skin were investigated in the cerebellum of barbiturate anaesthetized rats. 2. Climbing fibre responses were recorded in sagittally oriented microelectrode tracks across the mediolateral width of the anterior lobe. Climbing fibres with similar response latencies

Injury patterns and epidemiologic data from 211 moped accident victims and 214 motorcycle accident casualties admitted to hospital over a 5-year period (1977-1981) have been analyzed and compared. The number of those injured in motorcycle accidents tripled; the number of moped accident victims slightly decreased in the period studied. Differences in injury pattern, sex ratio, cause of accident, an

The paper examines the nonlinear behaviour of one- and two-degree-of-freedom discrete mechanical models subjected to partial follower load under conditions at which divergence instability occurs. Section (1.6) of the paper deals with the dynamic instability of an elastoplastic damped strut compressed by partial follower force at the free end. Space-time curves for the system are presented and disc
