Time-domain reflectometry probe for water content and electrical conductivity measurements in saline porous media
A new coated time-domain reflectometry (TDR) probe design is described and evaluated. In contrast to previous coated TDR probes, our probe may be used to measure both the dielectric constant (K-a) and bulk electrical conductivity (sigma(a)) in saline porous media. This was made possible by attaching two coaxial cables to a 0.27-m three-rod with a coated central rod. The shield of the first cable w
Type 1 Diabetes: Evidence for susceptibility loci from four genome-wide linkage scans in 1,435 multiplex families.
Type 1 diabetes is a common, multifactorial disease with strong familial clustering (genetic risk ratio [{lambda}S] ~ 15). Approximately 40% of the familial aggregation of type 1 diabetes can be attributed to allelic variation of HLA loci in the major histocompatibility complex on chromosome 6p21 (locus-specific {lambda}S ~ 3). Three other disease susceptibility loci have been clearly demonstrated

Neonatal pre-ganglionic sympathectomy affects morphometrically defined architecture in rat cerebral arteries
In order to clarify further the nature of the long-term influence on the cerebral vasculature by the sympathetic nerves, a bilateral cervical pre-ganglionic denervation was performed in 1-week-old rats. Four weeks later, morphometric determinations of the vascular dimensions revealed diminished media cross-sectional areas and luminal radii in the middle cerebral and posterior cerebral arteries, wh
Calpain activity in retinal degeneration.
Retinal degenerations such as retinitis pigmentosa (RP) or glaucoma are a major cause of blindness in humans. Understanding the mechanisms underlying the various types of retinal degeneration is a pre-requisite for the development of rational therapies for these diseases. Activation of the calcium dependent protease, calpain, has been suggested to play an important role in cell death in various ne

Frost sensitivity and nutrient status in a fertilized Norway spruce stand in Denmark
The aim of this study was to assess the effect of the N, P and K status on frost sensitivity of Norway spruce needles in a fertilization experiment situated in a nutrient poor 29-year-old Picea abies stand in western Denmark. The relative difference in frost sensitivity among trees was assessed by an index of injury, based on conductivity measurements of ion leakage from needles. Despite fertiliza
Differential expression of cytochrome c oxidase subunit III gene in castes of the termite Reticulitermes santonensis
Social insects such as termites live in colonies in which cooperation is assumed by all individuals developing into castes to which specific tasks are allocated. Little has been reported about molecular aspects underlying termite caste-specific gene expression. Genetic regulation has recently been hypothesized to govern caste-specific traits and physiology in social insects. Cytochrome c oxidase (

Lack of association between cystopathy and progression of diabetic nephropathy in insulin-dependent diabetes mellitus
Whether an association exists between cystopathy and progression of diabetic nephropathy has never been clarified. The aim of the present study was to measure the degree of cystopathy in relation to the rate of progression of diabetic nephropathy. To that end, 17 insulin-dependent diabetic patients with diabetic nephropathy but without voiding symptoms were investigated urodynamically. The median

Thermal double donor annihilation and oxygen precipitation at around 650 degrees C in Czochralski-grown Si: local vibrational mode studies
We have used local vibrational mode (LVM) spectroscopy to monitor the formation of oxygen-related thermal double donors (TDDs) at 45 0 degrees C and their annihilation at 650 degrees C in carbon-lean Czochralski-grown (Cz-) Si crystals. A few samples were treated at 650 degrees C under high hydrostatic pressure. It is found that the annihilation of TDDs at 650 degrees C results not only in a parti

Mechanical function of intermediate filaments in arteries of different size examined using desmin deficient mice.
Protein composition and mechanical function of intermediate filaments were examined in arteries of different sizes using desmin deficient mice (Des-/-) and their wild-type controls (Des+/+). Using SDS-PAGE gels and Western blots we found a gradient in desmin expression in the arterial tree; the desmin content increased from the elastic artery aorta, via the muscular mesenteric artery to the resist

An investigation has been made with the purpose to obtain information about evacuation capacity of various escape routes. Most of the data is although describing movement of people under normal conditions but some are coming from a test made to simulate fire and emergency situation. As a result of the investigation a number of diagrams are presented showing the walking speed and people flow in sta
Towards a learning organization: the introduction of a client-centered team-based organization in administrative surveying work.
Within administrative surveying work in Sweden, a transition to a client-centered team-based organization was made during 1998. The aim of this study was to describe the employees’ perceptions and expectations of job and organizational practices when working as a generalist in a client-centered team-based organization; job and organizational practices and well-being and effectiveness measures were
Gross nitrogen mineralization-, immobilization-, and nitrification rates as a function of soil C/N ratio and microbial activity
A laboratory experiment was designed to challenge the idea that the ON ratio of forest soils may control gross N immobilization, mineralization, and nitrification rates. Soils were collected from three deciduous forests sites varying in C/N ratio between 15 and 27. They were air-dried and rewetted to induce a burst of microbial activity. The N transformation rates were calculated from an isotope d
