The decays of the high angular momentum, high spin F-4(0) states of the electron configuration 3s3p3d in aluminium-like ions (with three electrons outside a closed shell) have been identified in delayed spectra of foil excited Ti, Fe and Ni ion beams. The line identifications were aided by HXR, MCHF, and MCDF calculations and are corroborated by lifetime measurements which demonstrate the differen

A state-dependent variable-gain control system is implemented to follow the characteristics of a laboratory-scale up-flow anaerobic fixed-bed reactor dynamically. The transition from one state to another is determined on an hourly basis, depending on difference between the setpoint of the reactor pH and its true value. Considerable improvement of the process stability - reduction of oscillation in

This thesis is about fixedness, or the process whereby orthographic words group together and congeal into fixed expressions that might subsequently reduce and become single words. The discussion focuses on three levels: realization, conceptualization, and discourse. At the level of realization, substitution tests have traditionally been employed to ascertain degrees of fixedness in expressions. T

Objective: In vivo electropermeabilization of cell membranes in rat muscle tissue cause a significant decrease of the electrical impedance, in the frequency region of 1-10 kHz. We aimed to study how the Tc-99m-DTPA uptake in the electropermeabilized region correlates to the change of admittance Y = 1/absZ, where Z is the measured impedance. Methods: The electropermeabilization was performed in viv

A large gravel pit 30 km north of the Pomeranian ice margin has been investigated. Besides gravel, sand, fines and diamicton, several deposits of organic material are present, some of them showing a typical Eemian Pollen- and macroflora. Previous interpretations assume that the sediments below the Eemian peat belong to the Saalian, and those above the peat to the Weichselian. Sorted sediments in t

In order to investigate whether c-Src is involved in carcinogenesis and progression of breast carcinoma, we examined the expression of activated c-Src in tissue sections from surgically resected human breast specimens. First, we confirmed the specificity of the antibody against activated c-Src (Clone 28) using six cell lines established from human breast carcinomas by western blotting. As expected

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.
