When creating finite element simulations, fasteners are often simplified or disregarded even though they are exposed to large loads and are reasons to cause failure in the model. Aimpoint AB produces electronic red dot sights that are exposed to high accelerations of at least 400G. The aim of this degree project is divided into two parts: develop and evaluate a test methodology for measuring strai
Given the widespread underemployment in Africa, on-the-job search represents a key channel through which individuals seek better employment oppor- tunities that value their skills and competences. However, empirical research on the determinants of on-the-job search has almost exclusively been conducted in advanced economies. The study aims to identify the determinants of on-the-job search among di
AimsAdipose tissue distribution, metabolism, and expansion capacity exhibit notable sex- and depot-specific differences. Herein, we monitored adipocyte traits related to insulin responsiveness and glucose transport during adipose expansion in visceral and subcutaneous fat from male and female mice.Material and methodsAdipocytes were isolated from perigonadal and inguinal adipose tissue of chow-fed
The subject of this thesis is theoretical examination of freezing phenomena inside fire sprinkler systems during activation at low temperatures in the surroundings. Many sprinkler systems are installed in environments such that they must be operable at subfreezing temperature conditions. During activation of such a system, water is assumed to penetrate a significant distance and without interrupti
Background: An increase in intestinal permeability and subsequent bacterial translocation has been demonstrated in critical illness. Cellulose derivatives have in the past been shown to reduce gut leakage following liver resection. Aims: The aim of the present study was to evaluate changes in microbial counts in experimental acute pancreatitis and the effect of pre-treatment with cellulose deriva
The degradation of technical toxaphene in water with two kinds of bioreactors operating in sequence was studied. One packed bed reactor was filled with Poraver(R) (foam glass particles) running at anaerobic conditions and one suspended carrier biofilm reactor working aerobically. Chemical oxygen demand (COD), chloride, sulphate, pH, dissolved oxygen, total toxaphene and specific toxaphene isomers
The human vestibulo-ocular reflex (VOR) leads to maintenance of the acuity of an image on the retina and contributes to the perception of orientation during high acceleration head movements. Our objective was to determine whether vision affects the horizontal VOR by assessing and comparing the performance at the boundaries of contribution of: (a) unrestricted visual information and (b) no visual i
The heart rate during atrial fibrillation (AF) is highly dependent on the conduction properties of the atrioventricular (AV) node, which can be affected using β-blockers or calcium channel blockers, often chosen empirically. Thus, characterization of the AV nodal conduction properties could contribute to personalized treatment of AF. We have created a mathematical network model of the AV node wher
Eastern Northeast Brazil (ENEB) generally experiences a high variability in precipitation in the dry season, with amplitudes that can overcome 500mm. The understanding of this variability can help in mitigating the socio-economic issues related to the planning and management of water resources this region, which is highly vulnerable to drought. This work aims to assess spatio-temporal variability
Background: Overnight fasting is often prolonged before scheduled surgery, and the extent of perioperative fluid replacement may influence outcome. In clinical practice, basic requirements are estimated at 1.2-2.0 mL·kg−1·h−1, but there is little contemporary clinical data on what deficits result from complete fasting. This prospective preclinical study was designed to determine total fluid loss d
Among birds, falcons are high-performance flyers, in many cases adapted for aerial hunting and hence suitable targets for investigating limits to flight performance. Using an optical range finder, we measured flight tracks of Eleonoras falcon (Falco eleonorae), a species breeding in the Mediterranean region and specialised for hunting autumn passage bird migrants, when commuting between their nest
The influence of choice of constitutive relation on the prediction of crack-opening stress for fatigue cracks using the finite-element method is investigated and compared with experimental results. Two different experimentally obtained stress–strain relations for IN718 at 550 °C were used for fitting material parameters to the linear kinematic and the Bodner–Partom viscoplastic constitutive models
Wars are generally characterized by inflationary issue of currency. War is a costly affair which makes excessive demands on the resources of a country so that a large part of the productive apparatus has to be geared to the war needs. The government of a country involved in war has to find new sources of finance to cover the high costs of labour and materials for the war effort which does not sati
AIM: The relative roles(s) of impaired insulin secretion vs. insulin resistance in the development of gestational diabetes mellitus depend upon multiple risk factors and diagnostic criteria. Here, we explored their relative contribution to gestational diabetes as defined by the WHO 1999 (GDM1999) and adapted WHO 2013 (GDM2013) criteria, excluding the 1-h glucose value, in a high-risk Indian popula
Proteolysis in skeletal muscle is mainly carried out by the activity of the ubiquitin-dependent proteolytic system. For the study of protein degradation through the ubiquitin-proteasome pathway, we used a model of hyperthermia in murine myotubes. In C2C12 cells, hyperthermia (41°C) induced a significant increase in both the rate of protein synthesis (18%) and degradation (51%). Interestingly, the
Exploring autonomic nervous system (ANS) changes during hypnosis is critical for understanding the nature and extent of the hypnotic phenomenon and for identifying the mechanisms underlying the effects of hypnosis in different medical conditions. To assess ANS changes during hypnosis, electrodermal activity and pulse rate variability (PRV) were measured in 121 young adults. Participants either rec
