Conventional cemented carbide is recommended for machining Ti6Al4V. However, polycrystalline diamond (PCD) and polycrystalline cubic boron nitride (pcBN) also show promise. Demands for higher productivity accelerate diffusional dissolution and chemically driven wear mechanisms in these tool materials. This study investigates active wear mechanisms by studying the interactions between Ti6Al4V and P

The human pathogen Streptococcus pyogenes causes substantial morbidity and mortality. It is unclear if antibodies developed after infections with this pathogen are opsonic and if they are strain specific or more broadly protective. Here, we quantified the opsonic-antibody response following invasive S. pyogenes infection. Four patients with S. pyogenes bacteremia between 2018 and 2020 at Skåne Uni

This article explores the relationship between architecture and public administration at the Swedish National Board of Public Building (Kungl. Byggnadsstyrelsen, or KBS) in the years 1963–74. This government agency, which existed from 1918 to 1993, was in charge of planning, designing, producing and maintaining public service buildings and facilities. During the 1960s, it was subject to a number o

Bakgrund: Tidig diagnos och behandling av bröstcancer-relaterade lymfödem(BCRL) är viktigt för att förhindra försämring och påverkan på livskvalitet. Vidmindre BCRL i arm, kan det ansamlas lymfvätska lokalt i den ytliga vävnaden, utan en volymökning. Tissue Dielectric Constant (TDC), är en metod som mäter lokal vävnadsvätska i hud och subkutan vävnad och hade inte använts tidigare för att diagnostBackground: Early diagnosis and treatment of Breast Cancer-RelatedLymphedema (BCRL) are important to prevent lymphedema progress and impacton Health-Related Quality of Life (HRQOL). The treatment includes self-care andtreatment with compression garment. In mild BCRL, the lymphedema can be local, without an increase in arm volume. Tissue Dielectric Constant (TDC), measuring local tissue water in sk

From liquefied human seminal plasma, we purified the predominant basic protein which appears following liquefaction of coagulated semen. The protein was purified in the presence of di-isopropylfluorophosphate to retard its degradation. Heparin-Sepharose® chromatography was followed by gel filtration (Biogel® P 60) and by fast performance liquid chromatography on a reversed phase column (C8). The b

Aggregation of the amyloid β-protein (Aβ) is believed to be involved in Alzheimer's disease pathogenesis. Here we have investigated the importance of the aromatic rings at positions 19 and 20 for the aggregation rate and mechanism by substituting phenylalanine with leucine. Aggregation kinetics were monitored as a function of time and peptide concentration by thioflavin T (ThT) fluorescence, the a

This paper is the state of the art of charcoal signal studies (macro-, meso- and micro-charcoal) that have been carried out at the Epigravettian settlement of Mezhyrich. This work took part of the French ANR project "Mammouths". Charcoal signals have been found in both natural and archaeological (pits and activity areas) deposits that have been sampled during the 2007-2008 archaeological excavatio

A bioanode with high current density and coulombic efficiency was developed by co-immobilization of pyranose dehydrogenase from Agaricus meleagris (AmPDH) with the dehydrogenase domain of cellobiose dehydrogenase from Corynascus thermophiles (recDHCtCDH) expressed recombinantly in Escherichia coli. The two enzymes were entrapped in Os-complex modified electrodeposition polymers (Os-EDPs) with spec

we present results that provide fundamental insights on how to experimentally tailor the planar defect density and even the crystal structure in III-V metal-particle-seeded nanowires, where zinc blende is the stable bulk crystal structure. We have grown GaP nanowires with metal-organic vapor-phase epitaxy under different conditions: pulsing of the Ga source, and Continuous growth with and without

Effects of dynamic ultra-high pressure homogenisation (UHPH) on the micro-and macrostructure of whey protein-depleted milk concentrate solutions with different mineral concentrations (5.0, 7.5, 10.0%, w/w), pH (5.8, 6.2, 6.6) and amount of added sodium chloride (0, 1.5, 3.0%, w/w) were investigated. Significantly increased viscosity was observed in samples at pH 5.8 without added NaCl and with UHP

The driving factors behind the global epidemic of obesity have not yet been fully elucidated. Investigating the effect of age and cohort on weight change might enable us to develop effective intervention strategies. Aims To analyse the pattern of BMI change by age and birth cohort over five-year follow-up in adult Swedish sample. Methods The data was drawn from the Scania Public Health Cohort. The

In other hazardous complex socio-technical systems in society, e.g. nuclear power and aviation, systems-theoretical assumptions are considered a promising way to better understand and manage safety. In this paper, two fundamental approaches to road safety were assessed in the light of a systems theory approach. One approach, is based on a premise where individual road-users are solely responsible

Zeaxanthin is a carotenoid produced by plants and has been associated with protection of the photosynthetic machinery under light stress and, together with lutein, in protection of the central retina of the eye. Zeaxanthin levels in blood plasma have been negatively correlated to the development of AMD (age-related macular degeneration) (Gale et al, 2003). Under normal conditions, plants have a lo

Grammar and epigram Grammarians of antiquity—the precursors later generations of classical philologists—were often the target of attacks by contemporary writers of satiric epigrams. Examples appear in collections of both Greek and Latin epigrams from the Hellenistic period down to the end of antiquity. Grammarians are generally depicted in them as pretentious humbugs, a pest both to poets, whose w

Popular Abstract in Swedish Avhandlingen beskriver utvecklingen av ett personlighetstest, Stress Strategy Test (SST), och hur detta test kan skilja på olika personer utifrån personlighet och de särskilda kognitiva strategier de använder sig av. Det relateras också till ett begåvningstest och psykologintervju av över tretusen individer. Testet bygger på den av J.R. Stroop uppmärksammade principenThe thesis concerns the development of a computerised test, termed the Stress Strategy Test (SST), intended for use in a personnel selection and placement context. A similar but less extended form of that test, termed the Stroop Strategy Test, developed first, was adjudged to be somewhat less effective as a selection instrument. Both of the tests, concerned with cognition, personality and ability

Miljöområdet är flervetenskapligt och komplexiteten i frågeställningarna är uppenbara. Utgångspunkten i avhandlingen är att anlägga ett pedagogiskt perspektiv på detta kunskapsområde. I boken ingår en undersökning av gymnasieelevers miljötänkande, och på vilket sätt skolans unConditions to promote students' knowledge and education about environment The objectives of this Study are: · To describe and analyse the development of students' knowledge about the environment · To elucidate the nature of student thinking about the environment and, from the findings, to suggest the potential of Environmental Education Environmental education is multi-disciplinary and complex.

Biological invasions often cause major perturbations in the environment and are well studied among macroorganisms. Less is known about invasion by free-living microbes. Gonyostomum semen (Raphidophyceae) is a freshwater phytoplankton species that has increased in abundance in Northern Europe since the 1980's and has expanded its habitat range. In this study, we aimed to determine the genetic popul

Despite evidence that both pollinators and nonpollinator agents of selection can shape the evolution of floral characters, there have been few attempts to compare the strengths and directions of selection from pollinators and other agents in the same study system. In this investigation of Leucanthemum vulgare, a self-incompatible composite known for its conspicuous white rays, I obtained data from

Aim: To investigate health-related quality of life (HRQoL) in young persons with limb reduction deficiency (LRD). Methods: One hundred and forty children with LRD aged 8-16 answered the DISABKIDS questionnaire for children with chronic health conditions. Of their parents, 137 answered a corresponding questionnaire concerning their child. Results: Compared to reference data from children with other
