In this paper, the dynamics of bicycles is analyzed from the perspective of control. Models of different complexity are presented, starting with simple ones and ending with more realistic models generated from multibody software. Models that capture essential behavior such as self-stabilization as well as models that demonstrate difficulties with rear wheel steering are considered. Experiences usi
Popular Abstract in Swedish Avfallshantering ägnas nuförtiden ett ökande intresse. Detta verk syftar till att analysera hur vanligt förekommande företagsekonomiska modeller och metoder liksom principen om att förorenaren betalar (The "Polluter-Pays Principle" (PPP)), generellt kan appliceras på management av avfallshantering och specifikt på segregering av olika avfallsfraktioner i syfte att medgeIncreased attention is nowadays devoted to waste management. The objective of this work is to analyse how commonly known business economic models and methods, as well as the Polluter-Pays Principle, can be applied to waste management in general and to waste fractionation in particular, so as to facilitate environmental optimisation of industrial and construction waste fractionation. In discussing
Purpose: The purpose of this clinical investigation was to evaluate the treatment outcome with zygoma implants with regard to implant survival, patient satisfaction, and function of prosthesis replacement after 3 years. Patients and Methods: The treatment outcome of 76 patients treated with 145 zygoma fixtures at 16 centers was evaluated with regard to implant survival. Status of peri-implant muco
Objective: To assess the effects of a 6-month angiotensin-converting enzyme (ACE) inhibitor intervention on myocardial ischaemia.Method: We randomized 389 patients with stable coronary artery disease to double-blind treatment with ramipril 5 mg/day (n = 133), ramipril 1.25 mg/day (n = 133), or placebo (n = 123). Forty-eight-hour ambulatory electrocardiography was performed at baseline, and after 1
Novel experimental results on mirror nuclei in the sd and fp shells are presented. Their respective Mirror Energy Difference (MED) diagrams are interpreted by means of large-scale shell-model calculations. A unique way of extracting effective charges from isospin symmetry studies is also discussed.
Several tests of human conscious knee proprioception have been described, but there is no consensus or reference standard established. Difficulties remain in the separation of information originating from muscles, tendons, and joints, and the tests cannot discriminate between loss of afferent signals or altered activity in the remaining receptors. There is convincing evidence from several descript
The thesis is a broad attempt to analyse economic forces behind, and economic rationales for, institutions that constrain the organisation and operation of insurance companies. The basic task is threefold: (i) to develop institutional theory by providing an outline of a transaction cost explanation of the origin of, and the rationale for, institutions that constrain the organisation and the operat
OBJECTIVES. The aim of this study was to evaluate whether a resuscitation strategy based on administration of 40% oxygen influences mortality rates and rates of improvement in 5-minute Apgar scores, compared with a strategy based on 100% oxygen administration. METHODS. A population-based study evaluated data from 4 Swedish perinatal level III centers during the period of 1998 to 2003. During this
Electrochemical real-time monitoring of ligand binding to an engineered opioid receptor specific for morphine is reported. In the particular systems studied, 90% of the binding was found to be completed after only 85-120 s. Thus, the binding kinetics has proven to be more rapid than previously believed. The observed association rate constant for the morphine binding reaction was calculated to be 2
In the male moth, Agrotis ipsilon, the neuronal basis for juvenile hormone (JH)-linked modulation of sex pheromone responsiveness was investigated following stimulation of the antenna with i) an extract of female pheromone gland, ii) the synthetic pheromone blends from A. ipsilon and a closely related species, A. segetum, and iii) single components of the A. ipsilon blend. Response characteristics
Objective. Renal concentrating capacity (RCC) has been used as a tool in the diagnosis of the site of urinary tract infection (UTI). In this study, RCC was measured in women with symptoms of UTI in relation to the clinical picture and the bacterial species isolated. Material and methods. In 633 outpatients aged >= 18 years with symptoms of UTI, a renal concentration test with desmopressin was perf
Popular Abstract in Swedish Avhandlingen fokuserar på den andra vågen av järnålderns centrala platser, vilka formerades under det långa 600-talet. Utgångspunkten är en fallstudie av en aristokratisk miljö i Järrestad, sydöstra Skåne. Två problemkomplex bearbetas. Tolkningen av de förkristna aristokratiska miljöerna. Syftet är att undersöka hur härskarideologier gestaltades i hallmiljön och det omThis dissertation focuses on the second wave of central places in south Scandinavia, emerging during the prolonged 7th century. The point of departure is a case study of an aristocratic setting in Järrestad, situated in the southernmost part of Sweden. Two problem complexes are tackled: 1. The interpretation of the pre-Christian aristocratic settings. The aim is to investigate the staging of rule
Previously we observed that neural cell adhesion molecule (NCAM) deficiency in P tumor cells facilitates metastasis into distant organs and local lymph nodes. Here, we show that NCAM-deficient P cell tumors grew leaky blood vessels with perturbed pericyte-endothelial cell-cell interactions and deficient perivascular deposition of ECM components. Conversely, tumor cell expression of NCAM in a fibro
In stroke patients several cardiac changes associated with embolism can be detected with transoesophageal echocardiography. Potential major cardiac embolic sources (e.g. atrial fibrillation, thrombi of left ventricle/atrium, vegetation, myxoma, dilated cardiomyopathy) have a causal relationship to embolism. Other changes with no certain causal relationship are regarded as potential minor cardiac e
Superdeformed and highly deformed rotational bands were established in Zn-65 using the Ca-40(Si-29,4p)Zn-65 reaction, and averaged quadrupole moments were measured for two of these bands. The configurations of these bands were assigned based on Hartree-Fock calculations. One of the three bands exhibits at low (h) over bar omega a rise in the J((2)) dynamic moments of inertia that is similar to the
