Popular Abstract in Swedish De semi-arida regionerna i norra Kina är drabbade av många faktorer som påverkar miljön negativt, t.ex. ökenspridning, vind erosion, överbetning, uttömmande av naturresurser. Det redan hårda trycket på ekosystemen i dessa regioner har ökat sedan Kina införde marknadsekonomi. Reformerna sedan 1978 har lett till en snabb ökning av antalet betesdjur och en expansion av jorLand degradation is commonly perceived to be severe in many parts of semi arid China. The transition towards market economy since the 1978 reforms, have set marginal dry lands under added pressure in the form of increased livestock numbers and expanding cultivation on erosive soils. To evaluate land degradation since the reforms, this study focuses on mapping and analysing the biological productio

The cellular and molecular pathways initiated by traumatic brain injury (TBI) may compromise the function and structural integrity of mitochondria, thereby contributing to cerebral metabolic dysfunction and cell death. The extent to which TBI affects regional mitochondrial populations with respect to structure, function, and swelling was assessed 3 hours and 24 hours after lateral fluid-percussion

Aims: To investigate whether a high level of commonly experienced physical and mental symptoms could predict long spells of sickness absence in Swedish women and, further, to investigate the causal pattern of socioeconomic and psychosocial factors in relation to long spells of sickness absence. Methods: A questionnaire containing items on socioeconomic and psychosocial variables was sent to a rand

A novel molecularly imprinted polymer was prepared by copolymerization of trimethylolpropane trimethacrylate (1) and methacrylic acid (3) in the presence of a dipeptide acting as the template. The recognition capability of the synthetic receptor-like binding sites produced in the polymer network for the peptide was demonstrated by using the polymer as a chiral stationary phase in HPLC. The polymer

Purpose - This paper aims to illustrate a new method to cluster consumer attribute preferences and to transform spontaneously written texts by consumers about a certain favourite food product (hamburger) into distinct preference clusters of attributes. Design/methodology/approach - A new way of finding significant clusters of consumer attribute preferences is developed by means of a new text analy

We have performed scanning tunnelling microscopy (STM) measurements of thin films of Co and CoPt alloys on Pt(111). In contrast to the interpretation of an earlier low energy electron diffraction investigation by Tsay and Shern [Surf. Sci. 396 (1998) 313] we find that the structure observed upon annealing a Pt(111) sample with a 2 ML (monolayer, ML) thick film of Co does not consist of a rotated C

The molecules of the title compound, C26H15N3S, have a pentacyclic ring system which is almost planar, with the central ring in a flattened boat conformation. The folding angle between the two quinoline rings is 6.75 ( 7)degrees. The 14- phenyl substituent is in a quasi- axial conformation, while the 14-cyano substituent is in a quasi- equatorial conformation with respect to the thiopyran ring. Th

Platelet-derived growth factor (PDGF)-D is a member of the PDGF/vascular endothelial growth factor family that activates PDGF receptor beta (PDGFR-beta). We show that PDGF-D is highly expressed in the myocardium throughout development and adulthood, as well as by arterial vascular smooth muscle cells (vSMCs). To obtain further knowledge regarding the in vivo response to PDGF-D, we generated transg

A numerical scheme for a stochastic partial differential equation of heat equation type is considered where the drift is locally bounded and the dispersion may be state dependent. Uniform convergence in probability is obtained.

This article analyses the consequences of using the concept of caregiving as a basis of extending social rights in the welfare state. By focusing on the administration of the right to a care allowance to a parent with a disabled child, the development of the concept of individualized justice and the use of discretion are examined. The article reveals how rights are differentially distributed throu

The Kalpha satellite spectra arising from the correlative multielectron processes accompanying K-shell photoionization of Ca, Ti and V were measured using a broad range crystal spectrometer. Multiconfiguration Dirac-Fock calculations were performed to interpret the observed,x-ray energies and the spectral line shape., The calculations agree fairly well with the experimental results. The variation

Background: Epidemiologic studies of associations between folate intake and breast cancer are inconclusive, but folate and other plant food nutrients appear protective in women at elevated risk. Objective: The objective was to examine the association between folate intake and the incidence of postmenopausal breast cancer. Design: This prospective study included all women aged >= 50 y (n = 11699) f

Objective: To investigate how first incidence of various mental disorders changed between the periods of 1947-1972 to 1972-1997 in the Lundby cohort. Method: First-incidence rates of mental disorders were calculated for two 25 year periods and ten 5 year periods. Results: From 1947-1972 to 1972-1997 a decrease in almost all age- and sex-specific incidences of neurotic and organic brain disorders w

The environmental impacts of landfills are associated mainly with the emission of leachate and biogas. Sanitary landfilling aims to stabilize the landfill in a efficient and controlled way, so that the environmental impacts are minimized. When a sanitary landfill has attained its final storage quality, it can be integrated into the environment. Both the presence and the flux of water play key role

BACKGROUND: An early age at menarche, a short menstrual cycle length, and a high age at first full term pregnancy or nulliparity are known risk factors for breast cancer. These risk factors have previously been reported to differ between breast cancer patients with and without a family history of breast cancer and also between breast cancer patients and controls. METHODS: Self-administered questio

BACKGROUND: The electrocortical background contains prognostic information in full-term asphyxiated newborn infants already during the first postnatal hours. In preterm infants with intra-ventricular hemorrhages (IVH) the background activity in EEG and amplitude-integrated EEG (aEEG) is depressed during the first days of life, and the extent of the depression correlates with the degree of IVH.
