Recent changes in land use and productivity in agro-pastoral Inner Mongolia, China

Popular Abstract in Swedish De arida och semi-arida grässtäpperna i Norra Kina anses vara svårt drabbade av markförstöring, främst genom vind- och vattenerosion, men även genom försaltning. Den rådande uppfattningen är att markförstöring och ökenspridningsproblematiken har eskalerat sedan införandet av de ekonomiska reformerna efter 1978, bl.a. genom en expansion av den odlade arealen på tidigare This study challenges the prevailing assumption that the expansion of cultivated land areas and increasing number of livestock in the agro-pastoral regions of northern China have aggravated the process of land degradation since the start of the rural reforms in 1978. Land-use and productivity trends in the Inner Mongolia Autonomous Region (IMAR), with special attention to the Keerqin steppe region

Differential effect of propofol on sympathetic neurotransmission in isolated human omental arteries and veins

1. The present study was undertaken to elucidate the effect of propofol on sympathetic neurotransmission in isolated human omental vessels. 2. Segments of both arteries and veins were exposed to 0, 10(-7), 10(-6), 10(-5) or 10(-4)M propofol, and studied in vitro to determine effects on: (i) isometric tension after electrical field stimulation (EFS) or after exogenous administration of noradrenalin

Hydrological processes in macrocatchment water harvesting in the arid region of Tunisia: the traditional system of tabias

In arid Tunisia, a tabia system is a traditional macrocatchment water harvesting system. It consists of a runoff area, which occupies two thirds of the slope arid is traditionally used for grazing; and one to five cropped plots within U-shaped soil banks arranged in a cascade in the third downstream area. These "run-on" areas accumulate and store the occasional runoff. Each soil bank is constructe

Recovery of cognitive and emotional functioning following withdrawal of topiramate maintenance therapy

The present investigation reports cognitive improvement following withdrawal of topiramate (TPM) maintenance therapy in two patients with intractable seizures. The first patient received a neuropsychological evaluation after 10 months of adjunctive TPM treatment and was reassessed after complete withdrawal. The second patient received a first evaluation without TPM therapy. A reassessment was cond

HIV/AIDS--information and knowledge: a comparative study of Kenyan and Swedish teenagers

Knowledge of hiv/aids, exposure to hiv/aids information and appreciation of given information was studied, by a questionnaire, among 326 Kenyan and 146 Swedish teenage school students in 1994. The aim of the study was to examine differences and similarities in knowledge in the two populations and to examine which sources of information about hiv and aids the respondents had been exposed to and whi

Late neonatal lupus erythematosus onset in a child born of a mother with primary Sjogren's syndrome

Background: The neonatal lupus syndrome can be present as congenital heart block (CHB) or as neonatal lupus erythematosus (NLE), both seldom passively acquired autoimmune diseases. CHB starts around week 20 of pregnancy and is a lifelong event, whereas NLE is self limiting and usually starts at the 6th week of the child's age - the maximum recorded up to week 20. Case report: An asymptomatic mothe

Nature and the Social Sciences : Examples from the Electricity and Waste Sectors

Popular AbstractWhen society first perceived the environmental condition as problematic, focus was on local emissions with local consequences. Subsequently, the center of attention partly moved beyond local effect research to a broader interest in, for instance, ecocycle processes of energy, and the whole lifecycle of materials. However, technological and natural scientific analyses of these phenoThe book has two interrelated objectives. One objective is meta-theoretical and concerns the exploration of theoretical debates connected to issues of studying society and environmental problems; another objective is empirical/analytical, referring to the analysis of "green" public participation in the electricity and waste sectors in Sweden, and partly in the Netherlands as well as the UK. The me

Cardiovascular responses to intravenous calcitonin gene-related peptide (CGRP) in the albino rabbit

The regional sensitivity of different vascular beds to i.v. CGRP was investigated in the albino rabbit by using the microsphere method. Experiments were performed without pre-treatment on both conscious and pentobarbital-anaesthetized animals. In addition, in one series on conscious animals, rabbits were pre-treated with indomethacin in order to reduce the formation of prostaglandins. In another s

Intrinsic inhibition of transcription factor E2A by HLH proteins ABF-1 and Id2 mediates reprogramming of neoplastic B cells in Hodgkin lymphoma

B cell differentiation is controlled by a complex network of lineage-restricted transcription factors. How perturbations to this network alter B cell fate remains poorly understood. Here we show that classical Hodgkin lymphoma tumor cells, which originate from mature B cells, have lost the B cell phenotype as a result of aberrant expression of transcriptional regulators. The B cell-specific transc

Slutredovisning från projekten "Brandteknisk dimensionering baserad på beräkning" (SBUF) och "Funktionsbaserad brandteknisk dimensionering" (Branndforsk)

This is a summary report of two integrated three year projects "Fire safety design based on calculations" and "Performance based fire safety design". The total project has been subdivided into several part projects: general principles for risk assessment, evacuation safety of public buildings, hotels and health care buildings, calculation of safety factors, calculation of model uncertainties, unce
