Venoarterial extracorporeal membrane oxygenation--how safe is it? Evaluation with a new experimental model

This study was undertaken to find out if about 25% right cardiac output is sufficient for preservation of lung function during prolonged periods of venoarterial extracorporeal membrane oxygenation. Six healthy pigs weighing 57 kg were subjected to 18-hour venoarterial extracorporeal membrane oxygenation. During this period 1200 ml/min venous blood was delivered to the lungs through the pulmonary a

Process Engineering Economics of Bioethanol Production

This work presents a review of studies on the process economics of ethanol production from lignocellulosic materials published since 1996. Our objective was to identify the most costly process steps and the impact of various parameters on the fi- nal production cost, e.g. plant capacity, raw material cost, and overall product yield, as well as process configuration. The variation in estimated etha

Ammoxidation of Toluene by YBa2Cu3O6 + x and Copper Oxides. Activity and XPS Studies

The catalytic activities of YBa2Cu3O6+x and copper oxides have been studied in the ammoxidation of toluene. At low oxygen pressures, over YBa2Cu3O6+x selective ammoxidation to benzonitrile occurs, whereas at high pressures, only total combustion of toluene to carbon oxides is observed. X-ray photoelectron spectroscopy (XPS) analysis of YBa2Cu3O6+x catalysts indicates predominance of Cu(I) states u

Steam drying a bed of porous spheres: Theory and experiment

The process of steam drying a bed of porous spheres is analysed in terms of a hybrid model that makes use of volume averaged transport equations for the fluid flowing in the bed and point equations for the heat and mass transport taking place in the spheres. To verify the model, a series of experiments with varying mass flux and steam temperature were carried out at atmospheric pressure using cera

Swedish registers to examine drug safety and clinical issues in RA

Data from several different monitoring systems are examined. The potential for registers based on data obtained from clinical practice, and linkage of such data to national health and population registers, is discussed. The approach described is a possible prototype for long term surveillance systems needed for the safe introduction of new treatments.

Climate and environment during the Younger Dryas (GS-1) as reflected by composite stable isotope records of lacustrine carbonates at Torreberga, southern Sweden

Climatic and environmental changes during the Younger Dryas stadial (GS-1) and preceding and following transitions are inferred from stable carbon and oxygen isotope records obtained from the sediments of ancient Lake Torreberga, southern Sweden. Event GS-1 is represented in the sediment sequence by 3.5 m of clay containing lacustrine carbonates of various origins. Comparison of isotopic records o

Cardiovascular morbidity and mortality associated with the metabolic syndrome

OBJECTIVE - To estimate the prevalence of and the cardiovascular risk associated with the metabolic syndrome using the new definition proposed by the World Health Organisation (WHO). RESEARCH DESIGN AND METHODS - A total of 4,483 subjects aged 35-70 years participating in a large family study of type 2 diabetes in Finland and Sweden (the Botnia study) were included in the analysis of cardiovascula

Development of a Test Procedure for Sandwich Panels using ISO 9705 Philosophy Nordtest Project nr 1432-99

Ett antal försök på olika typer av sandwichpaneler har genomförts. De valda sandwichpanelerna inkluderar de vanligaste kärnmaterialen. Två olika fullskaletester har genomförts. En av dem var utförd enligt ISO 9705 d.v.s. försök där panelerna var monterade inuti ett obrännbart rum. Det andra sättet av fullskaletesten var utförd genom att använda ett fristående rum under en stor kalorimeter. Denna kSummary : A number of tests have been performed on different types of sandwich panels. The chosen sandwich panels included most common core materials. Two types of full-scale tests were performed. One set was conducted according to ISO 9705 i.e. tests where the panels were mounted inside a non-combustible room. Another set of full-scale tests was performed using a free standing room under a large

Meat consumption in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohorts: results 24-hour dietary recalls

Objective: To evaluate meat intake patterns in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohorts. Design and setting: 24-Hour dietary recalls were assessed within the framework of a prospective cohort study in 27 centres across 10 European countries by means of standardised computer-assisted interviews. Subjects: In total, 22 924 women and 13 031 men aged 35-74 years.

Theoretical study of PbO and the PbO anion

PbO and PbO- were studied utilizing CCSD(T), CASSCF/CASPT2, and the Fock Space FSCCSD methods. Relativistic effects were treated by the spin-free, two-component infinite-order Douglas-Kroll-Hess, Dirac-Coulomb and the restricted active space state interaction RASSI-SO methods. Our adiabatic electron affinity (EA), 0.696 eV, agrees favorably with experiment (0.714 eV). Theoretical dissociation ener

How Swedish obstetricians manage hypertensive disorders in pregnancy. A questionnaire study

OBJECTIVE. To study treatment of hypertension in pregnancy in Sweden and compare our results with a similar study published in 1981. METHODS. A multiple choice questionnaire was sent to 92 obstetricians throughout Sweden and 88% responded. RESULTS. Most Swedish obstetricians would treat a woman in the second trimester with blood pressure 140/95 mmHg without antihypertensive medication (83%) in the

An electronic tongue in the dairy industry

The concept of electronic tongues or taste sensors has developed rapidly during recent years due to their large potential. They are based on electrochemical sensors combined with multivariate data analysis. Voltammetric electronic tongues have proven valuable in many applications. Due to their ruggedness and simplicity, they have been found especially suitable for on-line monitoring of industrial
