The function of a paper machine is to form the paper sheet and remove the water from the sheet. A modern paper machine is divided into three main parts, the wire section, the press section, and the dryer section. Although the dryer section is only responsible for removing less than 1% of the water volume in the original stock to the head box, this is the part of the paper machine that, by far, con

With standard and resonant x-ray magnetic diffraction we investigate the magnetic properties of Pt atoms in a Co/Pt(111) system. It is shown, that, depending on the thickness of the Co films, the magnetic anisotropy as monitored by the Pt magnetism changes from perpendicular to parallel, mimicking the behavior of the Co overlayer. Adsorption of carbon monoxide on very thin films has been found to

Purpose: To illustrate that the attenuation formula based on monochromatic radiation in homogeneous objects may be used for dose regulation in body computed tomography (CT) based on patient circumference and using a simple cloth measuring tape. Material and Methods: Based on the attenuation formula for monochromatic radiation, the following Microsoft Excel equation was derived: mAs(x)=mAs(n)* EXP(

This paper presents results of a survey on legislation regarding female genital mutilation in 15 European member states, as well as the results of a comparative analysis of the implementation of these laws in Belgium, France, Spain, Sweden and the UK. The research showed that although both criminal laws and child protection laws are implemented a number of difficulties with the implementation of t

(1) Thylakoids from spinach chloroplasts were phosphorylated, fragmented by sonication, and then fractionated by aqueous two-phase partitioning to yield membrane fragments, deriving from different structural domains of the membrane: grana, grana margins, grana core and stroma lamellae. The photochemical activities of PS I and PS II, located in the grana, and PS I and PS II, located in the stroma l

Outlines the development of PhD-education in the Nordic-Baltic area.

It has been stated many times that the formation of radiation infringements in PbWO4 is to a big extent stipulated by the non-stoichiometry defects of the crystals, arising in the process of their growth and annealing. To refine the idea of characteristics of the non-stoichiometry defects and their effect on the radiation hardness of PbWO4, the current study is aimed at the melt composition infrin

Enterobacter sp. strain D1 is a facultative anaerobic, Gram-negative heterotrophic bacterium isolated from toxaphene-contaminated soil. This organism was identified and characterized through phylogenetic and taxonomic studies. Based on 16S rDNA analysis, the strain D1 was clustered closely with the species Enterobacter cloacae subsp. dissolvens (LMG 2683) and E cloacae (ATCC 13047(T)). Strain D1 r

PURPOSE: To examine the clinical phenotype with emphasis on electroretinograms and visual fields in a Swedish family with X-linked retinitis pigmentosa (XLRP) type 2 (RP2), and compare it with Swedish XLRP families with the RP3 genotype. METHODS: Three affected brothers and their carrier mother were examined clinically and with kinetic perimetry, dark adaptation thresholds, and full-field electror

The shear strength of the interface between bone and an injectable calcium phosphate bone substitute that cures to form a carbonated apatite (Norian SRS) was measured and related to the time that elapsed between injury and surgery. Eleven rabbits had a 3 mm drill hole made in the retropatellar aspect of the distal femur. After one week, the rabbits were reoperated on and the hole filled with Noria

Social phobia is an anxiety disorder that is accessible to two forms of treatment yielding scientifically validated results: drugs and cognitive-behavioral therapies. Graded exposure to feared social situations is fundamental to obtain an improvement of the anxious symptoms. Traditionally, exposure therapies are done either in vivo or by imagining the situations. In vivo exposure is sometimes diff

Background: The classification of antineutrophil cytoplasmic antibody-associated vasculitis (AAV) and polyarteritis nodosa (PAN) for epidemiology studies is confusing. The existing schemes such as American College of Rheumatology (ACR) criteria, Chapel Hill Consensus Conference (CHCC) definitions and Lanham criteria produce overlapping and conflicting classifications, making it difficult to compar

We present morphological and molecular evidence of the occurrence of hybrids between great reed warblers Acrocephalus arundinaceus and clamorous reed warblers A. stentoreus in Kazakhstan where both species breed. Three males and one female of 249 examined individuals had wing characteristics that were intermediate between the parental species. Molecular analyses of a nuclear microsatellite locus a
