A coupled thermo-mechanical problem is presented in this paper. The constitutive model is based on thermoplastic model for large strains where both kinematic and isotropic hardening are included. It is shown that a non-associated plasticity formulation enables thermodynamic consistent heat generation to be modeled, which can be fitted accurately to experimental data. In the numerical examples the

The normal approach to digital control is to sample periodically in time. Using an analog of integration theory we can call this Riemann sampling. Lebesgue sampling or event based sampling is an alternative to Riemann sampling. It means that signals are sampled only when measurements pass certain limits. In this paper it is shown that Lebesgue sampling gives better performance for some simple syst
Popular Abstract in Swedish Sammanväxningar i buken utvecklas efter flertalet kirurgiska bukingrepp och utgör en betydande orsak till tarmvred, buksmärta och infertilitet. Buksammanväxningar skulle potentiellt kunna minskas i omfattning med användande av förebyggande behandling men här finns klara begränsningar i exempelvis effekt och ett stort utrymme för förbättring. De i denna avhandling ingåenPeritoneal adhesions develop after almost all abdominal surgical interventions and represent an important cause of postoperative intestinal obstruction, abdominal discomfort and infertility. Postoperative adhesions can potentially be reduced by using different antiadhesive agents. In the present study, we hypothesized that a combination of oppositely charged polypeptides could effectively decrease
Psychosocial stress has been linked to both hypertension and cardiovascular disease (CVD), and hypertension has been proposed to be one mediator of the increased CVD risk in subjects reporting stress. Genetic susceptibility for blood pressure elevation in relation to stress has been proposed, but so far there is little evidence. We aimed to study the prospective CVD risk of chronic stress (Pap
Decaline analogues of the bioactive fungal sesquiterpene (+)-isovelleral (1a), retaining the bicyclo[4,1,0]hept-2-en-1,2-dicarbaldehyde system, were prepared, and their cytotoxic and antimicrobial activities were compared with those of the natural product. While the two isomers (+/-)-2 and (+/-)-3 were as active as isovelleral (1a), the isomer (+/-)-4 was approximately 10 times less potent.
The gas phase far-IR spectrum of the small nu, Greek20 (A″, 367.88 cm−1) and small nu, Greek21 (A″, 311.28 cm−1) bands of 1,2,4-triazine, a five membered ring having the point group Cs, has been studied at a resolution ranging from 0.002 to 0.003 cm−1. From the MW spectrum 58 transitions in the small nu, Greek20 level and 64 in the small nu, Greek21 level have been assigned. The small nu, Greek20
BACKGROUND: Porcine embryonic neural tissue transplanted intracerebrally could potentially relieve the symptoms of Parkinson's disease if the immune response toward the graft could be overcome. However, conventional immunosuppressive treatments have proven inefficient in preventing rejection. An alternative is blocking the costimulatory signals for lymphocyte activation. Treatment with cytotoxic T
In the framework of the semi-hard (k(T)-factorization) approach, we analyze the various charm production processes in the kinematic region covered by the HERA experiments.
The gene encoding an alkaline active xylanase of Bacillus halodurans S7, containing an open reading frame of 1188 nucleotides encoding 396 amino acids, was cloned and expressed in Escherchia coli. On the basis of sequence similarity, possible -10 and -35, ribosome binding, and transcription terminator regions were identified. Analysis of the deduced amino acid sequence revealed that the protein wa
In the second of two papers, the atmospheric polybrominated diphenyl ethers (PBDE) deposition (wet and dry) at a municipal solid waste incineration (MSW) plant with electronics recycling is compared with that at an industrial urban reference site (URS) producing asphalt and concrete. Results of BDE209 and SigmaPBDE excluding BDE209 as representatives of "new" vs. "old" PBDEs are presented. Volume
We have previously reported a large Danish pedigree with autosomal dominant frontotemporal dementia (FTD) linked to chromosome 3 (FTD3). Here we identify a mutation in CHMP2B, encoding a component of the endosomal ESCRTIII complex, and show that it results in aberrant mRNA splicing in tissue samples from affected members of this family. We also describe an additional missense mutation in an unrela
During the last few years the home care services have had to face an increased responsibility for medical tasks. A study in the city of Malmö in 1993, repeated in 1998, shows that 95% of the health care assistants are engaged in the administration of medication. The studies demonstrate that health care assistants have inadequate knowledge not only about medicines and their administration but also
In order to assess the influence of severe hypoglycemia on local cerebral blood flow (1-CBF) artificially ventilated rats, maintained on 70% N2O, were injected with insulin to provide either an EEG pattern of slow-wave polyspikes, or cessation of spontaneous EEG activity for 5, 15 or 30 min ("coma"). In other animals, glucose was injected at the end of a 30 min period of "coma" and 1-CBF was measu
