Transvascular fluid exchange with application to the brain. An experimental study in cat skeletal muscle and brain.

Popular Abstract in Swedish MEKANISMER BAKOM VÄVNADSSVULLNAD MED INRIKTNING MOT DEN SKADADE HJÄRNAN. EN STUDIE PÅ SÖVD KATT. Störningar i vätskeflöden över ett organs minsta kärl, de s.k. kapillärerna, kan ge problem i form av vävnadssvullnad. Det är speciellt allvarligt när det sker i hjärnan eftersom hjärnan är innesluten i ett hårt skal och därför inte kan utvidga sig utan att trycket samtidigThis study evaluated transcapillary fluid exchange in the cat brain and in a cat skeletal muscle enclosed in a plethysmograph. A method for determination of capillary permeability (capillary filtration coefficient and reflection coefficient) and effects of transcapillary hydrostatic pressure changes were studied We found that capillary fluid permeability in a tissue can be determined by the capill

Simulation of the acoustics behind a wall due to a moving vehicle

The influence of a barrier on the acoustic field is investigated using an expansion of the compressible Navier-Stokes equations. Large Eddy Simulations (LES) is used to account for the acoustical sources and the equation for the acoustic density fluctuation accounts for the propagation of the acoustics waves. This combined approach enhances numerical efficiency while maintaining good accuracy. The

High performance 1 V 2.4 GHz CMOS VCO

A low phase noise 2.4 GHz voltage controlled oscillator (VCO) with 1 V supply is presented. The VCO is based on the differential negative resistance oscillator with the tail current source replaced by an inductor. The inductor both improves the noise factor of the oscillator and enables maximum voltage swing over the tank. The amplitude limitation which is usually set by the tail current source is

The inequality possibility frontier: the extensions and new applications

The paper extends the Inequality Possibility Frontier (IPF) approach introduced by Milanovic, Lindert and Williamson (2011) in two methodological directions. It allows the social minimum to increase with the average income of a society, and it derives all the IPF statistics for two other inequality measures than the Gini. Finally, it applies the framework to contemporary data showing that the ineq

Integrating Packaging and Logistics - Improving Supply Chain Performance

Packaging is a fundamental element in logistics systems. It not only affects every logistical activity; it also has a significant impact on logistics costs and performance. In order for packaging and logistics professionals to gain insight into packaging-dependent costs and performance, the interactions between packaging systems and logistics systems must be understood. The presented research prov

The effect of packing density on the startup and operation of an anaerobic single stage fixed wheat straw bed digester

In Southern Sweden, production of renewable energy from crop residues digestion is viewed as a worthwhile alternative. Also, the process gives valuable mineralised nitrogen as a by-product, which when produced at farm-scale can be recycled for ecological farming. It is difficult to achieve economic utilisation of crop residues in centralised slurry digestion, mainly because of the greater transpor

Fängelsebråk. Analyser av konflikter på anstalt

Massmedia sometimes report on quarrels, riots or violent escapes in prisons. This book takes the reader behind the headlines in order to present interviewed inmates' and staff members own descriptions and reflections on "jail quarrels". The author shows how the enforced intimacy of modern prisons creates peculiar patterns of both 'fighting mood' and its opposite: containment or 'prison stillness'.

Journalism Worthy of the Name: A Human Rights Perspective on Freedom within the Press

There is much tension between the conception of the press as a private enterprise subject to the logic of the market and the press as an instrument of democracy. One of the broken promises of democracy is the failure of the market in guaranteeing a vigorous political debate. The European Court of Human Rights has ascribed to the press the vital role of Public Watchdog, making it incumbent on it to

Realistic tissue dosimetry models using Monte Carlo simulations. Applications for radionuclide therapies

Popular Abstract in Swedish Vid radionuklidterapi används ett radioaktivt läkemedel för behandling av vissa sjukdomar, bl.a. struma och vissa tumörsjukdomar. En radionuklidmärkt målspecifik molekyl administreras till patienten och läkemedlet transporteras via blodomloppet till det sjuka området där molekylens egenskaper gör att läkemedlet ansamlas. Den joniserande strålningen som sänds ut från läkRadionuclide therapy (RNT) is a generic term for treatment modalities that use a radionuclide labeled to a target-specific molecule. This so-called radiopharmaceutical accumulates in the target, where the ionizing radiation damages the cells. At sufficient levels of radiation, the cells cannot repair themselves. The quantity of the energy deposited in a target region is referred to as the absorbed

On the Road. Paving stones past and present

We archaeologists are sensitive to the messages people convey through material culture. In Lund, paving stones carry a powrful message about Lund's 1,000-year-old history. However, paving stones are in fact a fairly recent phenomenon dating from the late 19th century. Thus, paving stones do not represent continuity in the longue duree, but they do represent our idea of what the past was like.

Similar software systems

During the last ten years or so, much effort has been spent on developing software architecture by analogy with hardware architecture from where the idea seems to originate. Much of the work has been devoted to specifying standard program units, called components, and their connections. The architecture is then the specific organization of these components and connections. In this paper, I suggest
