Wear mechanisms of uncoated and coated cemented carbide tools in machining lead-free silicon brass

Free-machining brass containing 2–3% of lead is a preferred industrial material as it shows excellent machinability where low cutting forces, short chips and reduced tool wear are attained. However this addition of lead, a highly toxic and hazardous material, leads to health and environmental issues. Alternative lead-free brasses are known for poor chip control and accelerated tool wear. The curre

Age-Related Changes in Immunological and Physiological Responses Following Pulmonary Challenge

Abstract: This review examines the current status of knowledge of sepsis and pneumonia in the elderly population and how the dynamics of the pulmonary challenge affects outcome and consequences. Led by an unprecedented shift in demographics, where a larger proportion of the population will reach an older age, clinical and experimental research shows that aging is associated with certain pulmonary This review examines the current status of knowledge of sepsis and pneumonia in the elderly population and how the dynamics of the pulmonary challenge affects outcome and consequences. Led by an unprecedented shift in demographics, where a larger proportion of the population will reach an older age, clinical and experimental research shows that aging is associated with certain pulmonary changes, b

Evolution and forcing mechanisms of El Niño over the past 21,000 years

TheEl Niño SouthernOscillation(ENSO) isEarth's dominant source of interannual climate variability, but its response to globalwarming remainshighly uncertain1.To improve ourunder standing of ENSO's sensitivity to external climate forcing, it is paramount to determine its past behaviour by using palaeoclimate data and model simulations. Palaeoclimate records show that ENSO has varied considerably si

Close to the edge: growth restrained by the NAD(P)H/ATP formation flux ratio

Most fermentative microorganisms grow well-under anaerobic conditions managing a balanced redox and appropriate energy metabolism, but a few species do exist in which cells have to cope with inadequate energy recovery or capture and/or redox balancing. Two cases of these species, i.e., the metabolically engineered Saccharomyces cerevisiae enabling it to ferment xylose and Lactobacillus reuteri fer

Neutrophil Trafficking in Pulmonary Inflammation: Monitoring Migration and Blockade with 111In-Labeled Leukocytes

AbstractAim: Although imaging of In vitro labeled leukocytes is commonly used for diagnosing inflammation and infection, data concerning the use of this technique to monitor neutrophil trafficking are scarce. Here we investigated thepotential of 111In-in vitro labeled leukocytes (InWBC) to monitor neutrophil trafficking in an animal model of pulmonary inflammation.Methods: F344 rats were divided i

To cooperate or not to cooperate ? : Collective action for rehabilitation of traditional water tunnel systems (qanats) in Syria

Communities all over the world are using traditional technologies to extract drinkingwater, irrigate their lands and feed their livestock. But these often sustainable and ancient ways to make use of groundwater are in rapid decline worldwide. A research project started in 1999 to study the rehabilitation of 1500-year old water tunnels called "qanats"in Syria. To Cooperate or not to Cooperate...? d

Eugenics and Racial Anthropology in the Ukrainian Radical Nationalist Tradition

Eugenics and race played significant roles in Ukrainian interwar nationalism, yet remain largely unstudied. The Ukrainian nationalists’ understanding of the racial makeup of their imagined community was contradictory as they struggled to reconcile their desire for racial “purity” with the realities of significant variations between the populations inhabiting the enormous territories which they sou

Remissvar om promemorian "Byte av målvariabel och introduktion av variansband" från Lunds Universitet

Lunds universitet har uppmanats att lämna ett yttrande på rubricerad remiss. Universitet avger härmed följande synpunkter som utarbetats vid Ekonomihögskolan av docent Fredrik NG Andersson och professor emeritus Lars Jonung. Lars Jonung var medlem av Finanspolitiska Rådet och dess ordförande 2012-13.Lunds universitet välkomnar i stort de två förändringar av inflationsmålet som Riksbanken har föres

Child physical abuse – High school students’ mental health and parental relations depending on who perpetrated the abuse

The aim of this study was to contribute to the research of child physical abuse (CPA) by examining if there were any differences in high school students’ mental health (in this study symptoms of depression and anxiety, self-esteem and sense of coherence) and/or, in how they perceive their parents, depending on whether or not they had been subjected to CPA during childhood. In addition, if high sch

The use of mutant proteins in protein adsorption studies

This paper presents some of the authors work on adsorption of proteins to solid interfaces, using sets of mutant proteins. The benefit of using mutants is that specific well-known changes can be made on the protein. Thus, only one property of the protein might be altered and a series of protein varying gradual in a protein characteristic can be produced. The systems presented in this paper are T4

Individual Defects in InAs/InGaAsSb/GaSb Nanowire Tunnel Field-Effect Transistors Operating below 60 mV/decade

Tunneling field-effect transistors (TunnelFET), a leading steep-slope transistor candidate, is still plagued by defect response, and there is a large discrepancy between measured and simulated device performance. In this work, highly scaled InAs/InxGa1−xAsySb1‑y/GaSb vertical nanowire TunnelFET with ability to operate well below 60 mV/decade at technically relevant currents are fabricated and char
