The effect of surface strain on the passive film evolution of SAF 2507 super duplex stainless steel exposed to ambient air and 0.1 M NaCl solution with varying anodic polarization at room temperature has been investigated using in-situ grazing incidence X-ray diffraction (GIXRD) in combination with electrochemical measurements. Surface strain affected the crystallinity of the passive film as such
MRI-based biophysical models are typically validated by comparison to ex-vivo histology of fixed tissue. The fixation process itself and the accompanied autolysis processes strongly modify tissue composition, and lead to MR signal changes, making the validation of biophysical models for in vivo MRI particularly challenging. To better understand the temporal evolution of the fixation process within
Popular Abstract in Swedish Inom svensk mjölkproduktion förekommer en hög frekvens av belastningsbesvär. Vid jämförelser mellan manliga och kvinnliga mjölkare har det visat sig vara stora skillnader avseende besvärsförekomst. Kvinnorna har rapporterat högre frekvens av problem i nästan alla kroppsdelar jämfört med männen. Dessutom har andelen hand- och handledsbesvär visat sig vara anmärkningsvärdThe aims of the thesis were to investigate the prevalence of the upper extremity musculoskeletal disorders in female milkers in relation to other occupational groups; to clarify the relationship between disorders and work environment, psychosocial and life style factors; to compare in a prospective study, pain, ache and discomfort reported by a questionnaire with clinical symptoms and sign; to exa
It is well documented that human modification of the hydrological cycle has profoundly affected the flow of liquid water across the Earth's land surface. Alteration of water vapor flows through land-use changes has received comparatively less attention, despite compelling evidence that such alteration can influence the functioning of the Earth System. We show that deforestation is as large a drivi
Becoming a father, especially for the first time, can present changes in men's identity and in the relationship with their partner. Affinity within the family and participation in the whole process of pregnancy, childbirth and the postnatal period are important for fathers' sense of postnatal security. The fathers want to be already prepared before birth for the early postnatal period. Willingness
PURPOSE: Sclerosing epithelioid fibrosarcoma (SEF) is a highly aggressive soft tissue sarcoma closely related to low-grade fibromyxoid sarcoma (LGFMS). Some tumors display morphological characteristics of both SEF and LGFMS, so called hybrid SEF/LGFMS. Despite the overlap of gene fusion variants between these two tumor types, SEF is much more aggressive. The present study aimed to further characte
African trypanosomes are responsible for significant levels of disease in both humans and animals. The protozoan parasites are free-living flagellates, usually transmitted by arthropod vectors, including the tsetse fly. In the mammalian host they live in the bloodstream and, in the case of human-infectious species, later invade the central nervous system. Diagnosis of the disease requires the posi
Radial velocity observations from three instruments reveal the presence of a 4 M Jup planet candidate orbiting the K giant HD 76920. HD 76920b has an orbital eccentricity of 0.856 ±0.009, making it the most eccentric planet known to orbit an evolved star. There is no indication that HD 76920 has an unseen binary companion, suggesting a scattering event rather than Kozai oscillations as a probable
INTRODUCTION: Poliomyelitis is currently a rare disease in developed countries, where only vaccinal strains seem to be in circulation, which replace wild poliovirus. Nevertheless, it is still a serious disease for children in underdeveloped countries of Asia and Africa.PATIENTS AND METHODS: We analysed nine strains of poliovirus type 2 isolated from the faecal matter of patients with vaccine assoc
Objective- The Wnt/β-catenin pathway orchestrates development of the blood-brain barrier, but the downstream mechanisms involved at different developmental windows and in different central nervous system (CNS) tissues have remained elusive. Approach and Results- Here, we create a new mouse model allowing spatiotemporal investigations of Wnt/β-catenin signaling by induced overexpression of Axin1, a
This paper gives an overview of some feedback & control systems at Synchrotron SOLEIL that are in use or in development today. Beam stability is crucial and adressed in all SOLEIL aspects; Fast Orbit Feedback is a multi-input multi-output control system made to stabilize beam position perturbations in the low- & high frequency band. In addition, active RF cavities are used to maintain stab
PURPOSE: To document and analyse the decision to withhold or withdraw life-sustaining treatment (LST) in a population of very old patients admitted to the ICU.METHODS: This prospective study included intensive care patients aged ≥ 80 years in 309 ICUs from 21 European countries with 30-day mortality follow-up.RESULTS: LST limitation was identified in 1356/5021 (27.2%) of patients: 15% had a withho
A cervical cytology biobank (CCB) is an extension of current cytopathology laboratory practice consisting in the systematic storage of Pap smears or liquid-based cytology samples from women participating in cervical cancer screening with the explicit purpose to facilitate future scientific research and quality audit of preventive services. A CCB should use an internationally agreed uniform cytolog
Probiotic bacteria provide unique opportunities to study the global responses and molecular mechanisms underlying the effects of gut-associated microorganisms in the human digestive tract. In this study, we show by comparative transcriptome analysis using DNA microarrays that the established probiotic Lactobacillus plantarum 299v specifically adapts its metabolic capacity in the human intestine fo
Introduction: The spatial peaks QRS-T angle accurately distinguishes children with hypertrophic cardiomyopathy from their healthy counterparts. The spatial peaks QRS-T angle is also useful in risk stratification for ventricular arrhythmias. We hypothesised that the spatial peaks QRS-T angle would be useful for the prediction of ventricular arrhythmias in hypertrophic cardiomyopathy patients under
PURPOSE: Hypermobility at the thumb carpometacarpal (CMC) joint has been proposed as an explanation for abnormal loading and subsequent development of osteoarthritis. Radiographic evaluation of this joint is difficult owing to the obliquity of the articulation. We modified a previously described technique to obtain a bilateral stress radiograph of the thumbs to measure CMC joint laxity. The purpos
Computer-based design analysis is nowadays of utmost importance for most engineering design projects. However, this brings some challenges, among them that of the collaboration between engineering designers and design analysts. Since they work with, and are responsible for, different areas, they do not necessarily have full insight into each other’s way of working. The issue of integration between
PURPOSE OF REVIEW: Moraxella catarrhalis is an emerging human-specific pathogen responsible for upper and lower respiratory tract infections. Understanding the events in the complex pathogenesis and underlying mechanisms during M. catarrhalis infection is a key to the development of novel therapeutics and vaccines. RECENT FINDINGS: Several novel findings have been reported on Moraxella pathogenesi
Water uptake on aerosol and cloud particles in the atmosphere modifies their chemistry and microphysics with important implications for climate on Earth. Here, we apply an environmental molecular beam (EMB) method to characterize water accommodation on ice and organic surfaces. The adsorption of surface-active compounds including short-chain alcohols, nitric acid, and acetic acid significantly aff
In searching for novel peptides with affinity for cadmium, the phage display technique was utilized. In the selection procedure, cadmium ions were immobilized on a metal chelating Sepharose gel. The peptides selected from a hexapeptide library showed no homology to naturally occurring metallothioneins. From the phage clones selected in the biopanning process, phages with affinity for Cd-109 in fre
