This study systematically investigates the passivation and dissolution mechanisms of TC4 (Ti-6Al-4V) in 3.5 wt% NaCl solution using in situ electrochemical atomic force microscopy (ECAFM), complemented by X-ray photoelectron spectroscopy (XPS) and X-ray absorption spectroscopy (XAS). Potentiodynamic polarization initially identified the electrochemical behavior of TC4, delineating passive, dissolv

Until now, computationally designed enzymes exhibited low catalytic rates1, 2, 3, 4–5 and required intensive experimental optimization to reach activity levels observed in comparable natural enzymes5, 6, 7, 8–9. These results exposed limitations in design methodology and suggested critical gaps in our understanding of the fundamentals of biocatalysis10,11. We present a fully computational workflow

The concept of integrated risk management (IRM) has developed as a response to more interconnected and complex contexts. To investigate how the concept is used and what is meant with integration in the scientific literature, a research profiling was carried out across all kinds of risk management applications. 1094 publications from scientific journals, conference proceedings, and books were inclu

Aim: To investigate the prevalence of eating and drinking difficulties as classified with the Eating and Drinking Ability Classification System (EDACS) in a large population-based cohort of children with cerebral palsy (CP) at all levels of motor function, and how EDACS classifications relate to undernutrition. Method: This was a cross-sectional study based on data from the Swedish CP follow-up pr

Objectives: To examine powered mobility learning in children with spinal muscular atrophy (SMA) type I, involving families and evaluating goal attainment through the use of small, modified electric toy cars in the children’s natural environments. Design: Single-blind pilot intervention study derived from an originally planned wait-list randomized controlled trial. This report includes only the imm

An experimental study on the duration of load effects in a glued shear plate dowel joint was conducted. The joint design features a single large diameter dowel for load transfers between members, via external steel plates, which are bonded to the timber with a low stiffness bond line. Due to the low bond line stiffness, the timber element is subjected to a close to uniform shear stress distributio

1. Hepatectomized rats were injected intravenously with doubly labelled ([14C]linoleic acid and [3H]palmitic acid) thoracic duct lymphs from rats fed cream, triolein or corn oil. The disappearance of the radioactive fatty acids of different molecular triacylglycerol species and of phospholipids from plasma was studied.2. 73–93% of the injected triacylglycerols had been cleared from plasma within 1

Companies share their intellectual property with potential competitors in many different ways, including patent pooling. A patent pool is an agreement between two or more patent owners to license one or more of their patents to one another or to third parties. In Europe the Commission used the term patent pool as the bringing together of the patents of two companies, which makes it available for u

Destructive leadership is a phenomenon widely known in organizations and may have severe consequences in high-risk environments such as the construction industry. The present study investigated the measurement of and relationship between safety climate, destructive leadership, and risk behavior on 2 construction sites in Sweden. It was assumed that the Destrudo-L exhibits at least an acceptable le

This bachelor thesis deals with the reporting around the demonstration in Gothenburg on September 30th 2017 arranged by Nordiska Motståndsrörelsen (NMR), a Nordic Neo-Nazi movement. After a cultural debate in Sweden regarding freedom of speech and the attendance of the internet based right-winged alternative media Fria Tider on Mässan Bok & Bibliotek, also known as Bokmässan, always arranged a

Förlust av biodiversitet är ett av de största globala miljöbetingade problemen idag. Arter står inför ökande och potentiellt synergistiska hot från markomvandling och överexploatering av naturresurser, från globala såväl som lokala socioekonomiska krafter. Populationerna av ryggradsdjur har mellan år 1970 och 2016 visat på en global genomsnittlig minskning på 68 procent. Större djur, s.k. megafaunThe critically endangered Sumatran rhinoceros (Dicerorhinus sumatrensis) has, due to previous hunting and habitat loss, diminished to a few non-viable and fragmented populations. Despite a relatively large amount of conservation efforts during the last 30 years, numbers are still declining. Accurate numbers today are unknown, since the species is rare. Information indicates that less than 100 indi

According to traditional research in subjective well-being, the more pleasant emotions we experience, the more satisfied with life we are. But according to newer research, our physical and mental health, including satisfaction with life, also depends on the emotional diversity between the positive and negative emotions we experience, and the difference between the emotions we desire and those we a

Studiens syfte var att undersöka om det fanns ett samband mellan anställningsotrygghet och upplevt psykiska välmående med det sociala samspelet mellan kollegor som en medierande effekt. Detta undersöktes genom en webbaserad enkät, där upplevt psykiskt välmående, anställningsotrygghet och det sociala samspelet mättes med konstruktestade formulär. Deltagarna (N=87) var anställda i livsmedelsbutiker The purpose of the study was to examine if there is a covariance between job insecurity and the experienced mental well-being with the factor social interaction between co-workers as a mediating effect. This was studied through a web survey where experienced mental well-being, social interaction and job insecurity was measured with construct validated surveys. The participants (N=87) were employee

Stabilitetsmätningar på bihålans storlek och O2-koncentration med hjälp av gasabsorptionsspektroskopi. Mätningar på bihålor med gasabsorptionsspektroskopi är stabila i tiden. Skillnader mellan den högra och vänstra sidan samt skillnader mellan individer har noterats. Bihåleinflammation är en vanlig sjukdom som i 85% av fallen orsakas av virus och i resterande fall av bakterier. Trots detta, försSinusitis is a common disease caused by a virus or bacteria, with 84% to 91% of cases caused by a viral pathogen. However, physicians prescribe antibiotics for this disease in 85% of all cases. GPX Medical is a company working on the development of a medical device which, by means of absorption spectroscopy, can determine whether the disease is caused by virus or bacteria supporting, thus, the doc

Metodutveckling i sökandet efter mikroplaster i tarminnehåll från tumlare Ett allt växande problem är ökande mängden mikroplaster i havet och hur de påverkar havslevande organismer. Mikroplast är små plastbitar som är mellan 0,1 - 500 mikrometer. De är uppdelade i primära och sekundära mikroplaster. Det har visat sig att båda typerna ackumuleras och stannar kvar i vattenlevande ekosystem där plasAn ever-growing problem is the increasing amount of microplastics in the sea and how they affect marine organisms. Microplastics are small pieces of plastic that are between 0.1 - 500 micrometres. They are divided into primary and secondary microplastics. Primary microplastics are those plastics that are intentionally produced to be microplastics. Secondary microplastics are generated from larger

Det har sagts att alla arkitekturepoker brukar nå sitt bottenmärke någonstans runt 30 år. Under en praktik på ett arkitektkontor upplevde jag det på egen hand när jag arbetade med ett område i Stockholm. Strategin för området är att riva stora delar av dess bebyggelse från 80- och 90-talet. Jag uppfattar strategin som ett uttryck för en allmän impopularitet av arkitekturen från denna period — den

Osteoarthritis is a widespread disease leading to physical disability affecting quality of life. It is primarily regarded as a cartilage disease but affect all tissues of a joint. Osteoarthritis can be regarded as an organ failure. Knee osteoarthritis is common in Kuwait, especially in women. The main symptoms are pain, stiffness and weakness affecting knee function. The diagnosis is made by histo

Complementary measures for the assessment of patient thermoregulatory state, such as subjective judgement scales, might be of considerable importance in field rescue scenarios where objective measures such as body core temperature, skin temperature, and oxygen consumption are difficult to obtain. The objective of this study was to evaluate, in healthy subjects, the reliability of the Cold Discomfo

BACKGROUND: The current trend of upgrading undervalued agricultural by-products involves the recovery of natural antioxidants. The purpose of this study was to recover phenols from fresh olive mill wastewater (OMW) with their dispersion in 85 mL ethanol per 100 mL and to investigate the effect of processing parameters on the phenol content and antioxidant capacity of the extracts. Moreover, all th

This paper presents a novel method for the analysis of heart rate variability (HRV) during exercise stress testing enhanced with respiratory information. The instantaneous frequency and power of the low frequency (LF) and high frequency (HF) bands of the HRV are estimated by parametric decomposition of the instantaneous autocorrelation function (ACF) as a sum of damped sinusoids. The instantaneous
