A part of this thesis has been devoted to present general recuperator technology such as available gas turbine recuperator types, applications where recuperators are utilized, recuperator materials etc. An investigation of some compact and highly efficient heat transfer surfaces, for intended use in gas turbine recuperators, include the following surfaces: · Cross Wavy (CW) primary surface. · Cor

A new flow-through electrochemical microcell was fabricated, in order to be used as an on-line detector in microdialysis-based investigations. The microcell is obtained by sandwich-like assembling the electrode system patterned on a glass chip and a silicon rubber gasket bearing the fluidic elements (inlet, outlet, flow channel, and containers for reference and counter electrode). Four Pt microele

The use of physiological data from human tests in modelling should consider background data, such as activity, environmental factors and clothing insulation on the whole body. The present paper focuses on local thermal comfort of feet with special attention on the effects of physical changes of footwear thermal properties. An alternative test method is available for footwear thermal testing beside

Popular Abstract in Swedish Livstidsprevalensen för läkemedelsberoende hos alkoholberoende patienter varierar mellan 20% och 45%. I normalbefolkningen är livstidsprevalensen av läkemedelsberoende cirka 2%; livstidsprevalensen för beroende av bensodiazepiner (BZD) respektive legala opioider (metadon exkluderat) är 0.3-0.9% respektive 0.8%. Förskrivningen av BZD har de senaste åren legat konstant elThe thesis contains 4 papers, two clinical studies and two meta-analyses. In the BZD taper study (Paper I) 21 BZD dependent (DSM-IV) patients were included for a 10-day inpatient detoxification. The average defined daily dose (DDD) was 4.7 doses. Withdrawal symptoms were not more pronounced compared to more extended detoxification procedures reported in literature. Five patients, all with concomi

Introduction. An open collaborative international network has been established which aims to improve inter-centre standards for collection of high-resolution, neurointensive care data on patients with traumatic brain injury. The group is also working towards the creation of an open access, detailed and validated database that will be useful for post-hoc hypothesis testing. In Part A, the underlyin

Diethylhexyl phthalate (DEHP) is widely used as a plasticizer in consumer products and is known to disturb the development of the male reproductive system in rats. The mechanisms by which DEHP exerts these effects are not yet fully elucidated, though some of the effects are related to reduced fetal testosterone production. The present study investigated the effects of four different doses of DEHP

By means of atomistic molecular dynamics simulations, we study cholesterol-DPPC (dipalmitoyl phosphatidylcholine) bilayers of different composition, from pure DPPC bilayers to a 1:1 mixture of DPPC and cholesterol. The lateral pressure profiles through the bilayers are computed and separated into contributions from the different components. We find that the pressure inside the bilayer changes qual

In this thesis we present new worst case computational bounds on algorithms for some of the most well-known NP-complete and #P-complete problems and their optimization variants. We consider graph problems like Longest Path, Maximum Cut, Number of Perfect Matchings, Chromatic and Domatic Number, as well as Maximum k-Satisfiability and Set Cover. Our results include I a) There is a polynomial--

Background: Lack of generalized guidelines for DNA flow cytometric analysis (FCM) may be the main reason for its limited use in the clinical management of breast cancer. Methods: After an initial interlaboratory reproducibility study (Round 1), we concluded that it was the evaluation of the DNA histograms rather than the technical performance of the analysis that was the main reason for discordant

The structure of the N=Z nuclei Zn-60, Ga-62, Ge-64 and Kr-72 has been investigated at GASP spectrometer through the S-32 + Ca-40 and Ca-40 + Ca-40 reactions at 140 and 160 MeV, respectively, using reaction channel selection with the ISIS Si-ball. The high spin states of such nuclei have been investigated searching for the four quasi-particle g(9/2) alignment. TRS calculations have been performed
