In this paper we study the distribution of the product of an inverse Wishart random matrix and a Gaussian random vector. We derive its asymptotic distribution as well as its approximate density function formula which is based on the Gaussian integral and the third order Taylor expansion. Furthermore, we compare obtained asymptotic and approximate density functions with the exact density which is o

The consolidation of paper during drying is of interest to increase the understanding of the development of the paper quality. The mercury displacement technique proved suitable to measure the apparent solid density and the volume fractions of solid, liquid and gas in wet paper sheets. Measurements were performed on handsheets of chemi-thermomechanical pulp (CTMP), bleached and unbleached softwood

Popular Abstract in Swedish Blodkärlens insida bekläds av ett lager platta celler, s.k. endotelceller. Syrgas, näring och hormonella signaler måste passera dessa celler för att nå ut till kroppens olika vävnadsceller. På endotelcellernas yta finns normalt strukturer som förhindrar att blodceller (vita blodkroppar och blodplättar) fastnar och därigenom underlättas blodflödet. Endotelcellerna bildarThe vascular endothelium is an important regulatory organ in circulatory physiology and plays a central role in the response to acute inflammation and ischemia/reperfusion. Activation and dysfunction of the pulmonary vascular endothelium are closely related to clinical findings of pulmonary dysfunction. The endothelial-derived relaxing factor, nitric oxide (NO), is a gas, which can be administered

Using the findings of incident investigations to improve patient safety management is well-established and mandatory under Swedish law. This study seeks to identify the mechanisms behind successful implementation of the recommendations of incident investigations.

The present paper explores possible reasons why acceptance and mindfulness techniques may be beneficial in the treatment of insomnia. First, it is argued that sleep is facilitated by cognitive deactivation, with less controlled information processing as compared with daytime functioning, and correspondingly more acceptance of spontaneously occurring physiological and mental processes. Second, it i

BACKGROUND: The study is part of a collaborative project (Inuendo), aiming to assess the impact of dietary persistent organochlorine pollutants (POPs) on human fertility. The aims with the present study are to analyze inter-population variations in serum concentrations of 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153) and 1,1-dichloro-2,2-bis (p-chlorophenyl)-ethylene (p,p'-DDE), to assess inter-popul

This study aimed to establish whether the temperature-dependent effect of acidification on maximum force observed in mammalian muscles also applies to frog muscle. Measurements of force, stiffness, and unloaded velocity of shortening in intact single muscle fibers from the anterior tibialis muscle of Rana temporaria were performed between 0 and 22degreesC during fused tetani in H2CO3CO2-buffered R

Poly(D,L-lactide-co-glycolide) (PLG) is probably the biodegradable polymer most often used for polymeric controlled-release formulations. Different salts have been shown to affect the swelling and degradation of PLG, which, in turn, affect the release of encapsulated drugs. In this investigation the effect of divalent cations was especially investigated. Films of PLG were incubated in phosphate bu

In service life modeling of concrete, the ion transport in the pore solution is crucial. The main deterioration phenomena associated with ions in the pore solution are (1) corrosion due to external chloride ions reaching the embedded reinforcement bars; (2) carbonation due to presence of dissolved carbon dioxide (which will form carbonic acid with water) supplied from the surrounding air; and (3)

Background: The postantibiotic effect (PAE) of meropenem and ciprofloxacin was studied in the presence of the antineoplastic agent 5-fluorouracil (5-FU). The purpose of the study was to investigate whether the PAEs of the combinations differed from the PAEs of the antibiotics alone. Methods: The PAEs of the combinations of 5-FU plus meropenem or ciprofloxacin were determined with viable counts aga

The need to estimate indoor temperatures, heating or cooling load and energy requirements for buildings arises in many stages of a buildings life cycle, e.g. at the early layout stage, during the design of a building and for energy retrofitting planning. Other purposes are to meat the authorities requirements given in building codes. All these situations require good calculation methods. The main

The available evidence suggests that both genes and environment play a crucial role in the development of juvenile-onset myopia. When the human visual system is examined from an evolutionary perspective, it becomes apparent that humans, living in the original environmental niche for which our species is genetically adapted (as hunter-gatherers), are either slightly hypermetropic or emmetropic and

Electronic structure of two conjugated polymers, PPV and its derivative DIOXA-PPV, are studied by quantum-chemistry methods. Good agreement between the calculations and available experimental data validates the applied methods and enables us to draw conclusions about properties of excitons and polarons in these polymers. In particular, simultaneous use of different correlation plots in atomic site

Estimates of viability as measured by vital staining with fluorescein diacetate (FDA) were carried out on freshly isolated and partially aged (16-h-old) B. vulgaris and H. vulgare mesophyll protoplasts following irradiation with UV-B. Damage to the photosynthetic system by UV-B was determined by delayed light emission (DLE). In the case of freshly isolated protoplasts Beta was .apprx. 30% more sus
