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

Direction of galvanically-induced vestibulo-postural responses during active and passive neck torsion

The direction of a postural response induced by galvanic vestibular stimulation depends on the head and trunk position. The relative importance of afferent information (proprioception) and efferent motor command/corollary discharge is unknown. We studied the direction of body sway evoked by galvanic vestibular stimulation in 9 healthy subjects during active and passive head positioning at 0 degree

Use of ciprofloxacin in patients undergoing transurethral prostatic surgery

The efficacy of a short (Group I) and a prolonged (Group II) course with ciprofloxacin was assessed in patients undergoing transurethral prostatic resection and compared with that of controls without antibiotic (Group III). Both regimens significantly reduced the frequency of post-operative bacteriuria (p less than 0.01) and of severe infectious complications (p = 0.004) compared to the controls.

Structure prediction and fold recognition for the ferrochelatase family of proteins

An alpha/beta barrel is predicted for the three-dimensional (3D) structure of Bacillus subtilis ferrochelatase. To arrive at this structure, the THREADER program was used to find possible homologous 3D structures and to predict the secondary structure for the ferrochelatase sequence. The secondary structure was fit by hand to the selected homologous 3D structure then the MODELLER program was used

Signal frequency studies of an environmental application of a 65 nm region ion sensitive field effect transistor sensor

A rapid and sensitive novel type of bioelectronic Region Ion Sensitive Field Effect Transistor (RISFET) nanosensor was constructed on a chip with a 65 nm sensing electrode gap. The RISFET nanosensor was demonstrated for the environmental pesticide analysis of neurotoxic organocarbamate/carbofuran. The linear range for carbofuran analysis is ac signal frequency dependent, studied in the range (500

Utrymningsvägars fysiska kapacitet. Sammanställning och utvärdering av kunskapsläget

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

A system perspective on the heating of detached houses

Primary energy use, emission and the cost of whole energy system chains, from natural resource to end-User, were analysed, in a Swedish context,, hen heating detached houses. Both electricity-based systems employing heat Pumps. boilers. or resistance heaters. and local fuel-based systems (e.g. natural gas. oil and wood fuel) were considered. The base-load electricity was Produced in stand-alone po

The Swedish knee arthroplasty register. A nation-wide study of 30,003 knees 1976-1992

1976 through 1992, 30,003 primary knee arthroplasties and their revisions have been recorded in a nation-wide Swedish study. We report on the structure of the register, demographic data and survivorship. We found that operations for osteoarthrosis (OA) counted for the increase in number of arthroplasties in contrast to rheumatoid arthritis (RA), where the number had slightly declined. For primary

Phase equilibria of model milk membrane lipid systems.

The phase behaviour of mixtures of recombined milk membrane lipids dioleoylphosphatidylcholine (DOPC), sphingomyelin (SM), dioleoylphosphatidylethanolamine (DOPE), phosphatidylinositol (PI) and dioleoylphosphatidylserine (DOPS) in 60% water was examined as a function of temperature between 5 and 90 °C. The aim was to examine under which lipid composition the average properties turn from balanced o

Moral reasoning: The influence of affective personality, dilemma content and gender

This study examined the influence of affective personality, perfectionism, gender, arousal and dilemma content on moral reasoning. 264 participants were presented with moral dilemmas to which they had to provide a solution that reflected various degrees of justice and care. The results indicated that a) affective personality had an effect on moral reasoning, b) female participants reported higher

Det förgångna är framtiden : Ursprungsfolk och självbestämmande i Hawai´i

Popular Abstract in Swedish Det förgångna är framtiden är en socialantropologisk studie av ett politiskt skeende som pågått under de senaste 20 åren och som handlar om hur ursprungsfolket kanaka maoli i Hawai´i fått rätt till självbestämmande och andra särskilda rättigheter. Kanaka maoli har använt en diskursiv strategi som handlat om att de en gång i tiden varit ursprungligt suveräna och att dennThe sovereignty- and self-determination movements of indigenous peoples are a salient factor on the political agenda in many western world countries. Indigenous peoples in Hawai´i and elsewhere have become increasingly politicised in hope of changing their relationship with the states within which they are located. The discourse of indigenous peoples turn around the concept ”First Nations” whose c
