In meteorological applications psychrometers are used both as a humidity transfer standard and as a measurement instrument. Unfortunately wet bulb temperature, t(wb), is not a thermodynamic property and consequently, in equation linking vapor pressure and temperature, the psychrometer constant, from now on called the psychrometer coefficient, a, must be experimentally evaluated. Both theoretical f
The > 10,000 living venomous marine snail species [superfamily Conoidea Fleming, 1822] include cone snails (Conus), the overwhelming focus of research. Hastula hectica (Linnaeus, 1758), a venomous snail in the family Terebridae Morch, 1852 was comprehensively investigated. The Terebridae comprise a major monophyletic group within Conoidea. H. hectica has a striking radular tooth to inject venom th
BACKGROUND: Epicardial mapping is a powerful tool that has enabled us to gain insight into the electrical phenomena perpetuating atrial fibrillation and has guided the design of surgical and catheter-based therapeutic strategies. However, epicardial data are acquired during abnormal physiological conditions; the patients are anaesthetized, their chests opened, dislocating the heart and exposing it
PURPOSE: The aim of this study was to compare oral health status on a geriatric rehabilitation ward among patients who were assessed using the Revised Oral Assessment Guide (ROAG) on admission and at discharge; and to investigate in what respect the oral health procedures (OHP) suggested in ROAG were applied when oral health problems were detected. MATERIALS AND METHODS: Registered nurses on the w
The purpose of this article is to describe three cases of kissing stent placement in the common femoral artery bifurcation in patients unsuitable for open endarterectomy and patch plasty. In three patients with critical limb ischemia, caused by primary atherosclerotic disease or dissection-related injury when performing a lower extremity intervention, a technique of kissing stents was used to trea
The aim of this study was to investigate self-theories (theories of intelligence, confidence in one's intelligence, internal attribution of failure, academic self-efficacy), specific control, and experiencing of stress by means of a questionnaire for 915 Swedish high school students. Factor analysis yielded 6 stress domains (Workload, Psychosocial Problems, Uncertainty, Problems in Close Relations
A comparative study was performed to reveal differences and relative figures of merit of seven different calculation algorithms for photon beams when applied to inhomogeneous media. The following algorithms were investigated: Varian Eclipse: the anisotropic analytical algorithm, and the pencil beam with modified Batho correction; Nucletron Helax-TMS: the collapsed cone and the pencil beam with equ
The bacterial flora of the intestine and the bacteria found in liver, mesenteric lymph nodes, portal and arterial blood after D-galactosamine-induced liver injury, with and without pretreatment with Lactobacillus plantarum DSM 9843, were studied in the rat. Dominating representatives were identified to species level by 16S rDNA sequencing and typed by randomly amplified polymorphic DNA (RAPD) and
Background: Four principles are used to distribute payments via the Swedish social-insurance system in cases of temporary or permanent illness and death. This paper studies the redistributive effects on income of these four principles. Methods: The analysis is based on aggregate social-insurance data from the 25 municipalities that comprise Stockholm County in Sweden. For nine different types of s
The interaction between the nonionic polymer poly(ethylene oxide) (PEO) of molecular weight 20 000 and surfactants of various types [sodium dodecyl sulfate (SDS), dodecyl trimethylammonium bromide, octyl beta-D-glucoside, and potassium laurate] has been investigated in an aqueous solution at 25 degreesC by H-1 NMR pulsed-gradient spin-echo self-diffusion techniques. The SDS/PEO study was further c
PURPOSE: In order to increase the theoretical understanding of the concept of accessibility, this paper reports the results from an exploration of methodological difficulties inherent in systematic accessibility assessments of single persons' travel chains in urban public bus transport. In addition, Special Transport Service (STS) travellers' perception of environmental demands in public transport
The protein C system provides important control of blood coagulation by regulating the activities of factor VIIIa (FVIIIa) and factor Va(FVa), cofactors in the activation of factor X and prothrombin, respectively. The system comprises membrane-bound and circulating proteins that assemble into multi-molecular complexes on cell surfaces. Vitamin K-dependent protein C, the key component of the system
The objective of this article is. to analyse the utilization of two academic narratives about innovation policy in policy discourse by examining the policy statements issued by one Swedish agency that was specifically set up to promote innovation policy, the Swedish Agency for Innovation Systems, VINNOVA. The main findings of this analysis show that the deployment of the examined academic narrativ
HSEPI (glucuronyl C5-epimerase) catalyzes the conversion of D-glucuronic acid to L-iduronic acid in heparan sulfate (HS) biosynthesis. Disruption of the Hsepi gene in mice yielded a lethal phenotype with selective organ defects but had remarkably little effect on other organ systems. We have approached the underlying mechanisms by examining the course and effects of FGF2 signaling in a mouse embry
Objective. To evaluate if magnetic resonance imaging (MRI) is superior to conventional radiography for detection of erosions in the fifth metatarsophalangeal (MTP5) joint. Methods. Within one year from the onset of rheumatoid arthritis (RA) (baseline), one and three years thereafter MRI and conventional radiographs of the MTP5 joint were performed in 23 patients. Results. MRI revealed erosions in
We use a linear autoregressive model to describe the movement of a soil-living insect, Protaphorura armata (Collembola). Models of this kind can be viewed as extensions of a random walk, but unlike a correlated random walk, in which the speed and turning angles are independent, our model identifies and expresses the correlations between the turning angles and a variable speed. Our model uses data
The role played by histamine from enterochromaffin-like (ECL) cells and mast cells in gastric acid secretion and in the development of ethanol-induced gastric lesions was studied in the rat. This was done by examining the effects of inhibition of the histamine-producing enzyme histidine decarboxylase (HDC) with alpha-fluoromethylhistidine (alpha-FMH) and the effects of degranulation of the mucosal
