Computational Methods in Conceptual Structural Design

Conceptual design is the first phase in the design process in which all the requirements and design objectives are synthesized into conceptual alternatives. In practice today, major decisions regarding the buildings function, massing, and overall form are usually made during the first phase. Considering structural performance requirements during conceptual design enhances interdisciplinary interac

Generating initial reinforcement layouts using graphic statics

A key step to the strut-and-tie method is the selection of an appropriate truss model, due to the static indeterminacy of reinforced concrete there are often several suitable models possible. A method for automatically generating a suitable truss model by using graphic statics is presented. Optimal layouts are found by minimizing the total load path. A formulation of constraints suitable for gener

Unravelling protein stability and aggregation

Proteiner är fascinerande makromolekyler som är fundamentala för alla levandeorganismer. De utgör byggstenar i våra celler, ansvarar för transport och signalering både inom och mellan våra celler, utgör en del av vårt immunförsvar och katalyserar bildningen av andra molekyler. Proteiner består av flexibla kedjor uppbyggda av olika aminosyror. Varje aminosyra har olika egenskaper och den specifika Proteins are complex macromolecules that are fundamental to all living species. The stability of proteins are governed by non-covalent forces within the protein and between the protein and its surrounding environment. At high concentrations proteins are susceptible to self-association, which may lead to amyloid fibril formation – a process linked to many diseases, such as Alzheimer’s disease, Park

Cost-effectiveness of optimized adherence to prevention guidelines in European patients with coronary heart disease : Results from the EUROASPIRE IV survey

Background: This study aims to assess the cost-effectiveness of optimized guideline adherence in patients with a history of coronary heart disease. Methods: An individual-based decision tree model was developed using the SMART risk score tool which estimates the 10-year risk for recurrent vascular events in patients with manifest cardiovascular disease (CVD). Analyses were based on the EUROASPIRE

Sesquiterpene lactones from Ambrosia arborescens Mill. inhibit pro-inflammatory cytokine expression and modulate NF-κB signaling in human skin cells

Background: Ambrosia arborescens has been used in Andean traditional medicine to reduce problems associated with various inflammatory diseases and conditions, although the underlying mechanism is unknown. Hypothesis/purpose: The sesquiterpene lactones (SLs) coronopilin and damsin, which are major secondary metabolites of A. arborescens, have anti-inflammatory activity by attenuation of IL-6 and MC

Constraints on off-shell Higgs boson production and the Higgs boson total width in ZZ → 4ℓ and ZZ → 2ℓ2ν final states with the ATLAS detector

A measurement of off-shell Higgs boson production in the ZZ→4ℓ and ZZ→2ℓ2ν decay channels, where ℓ stands for either an electron or a muon, is performed using data from proton–proton collisions at a centre-of-mass energy of s=13 TeV. The data were collected by the ATLAS experiment in 2015 and 2016 at the Large Hadron Collider, and they correspond to an integrated luminosity of 36.1fb−1. An observe

Core values work in academia : – with experiences from Lund University

What are core values and what use are they? How can the central governmentcore values translate to academia? Why do the ‘statutory’, political valuesend up in conflict with academic values based on the specific culture ofuniversities? What methods and what examples exist for active and effectivecore values work at a university? And how do you implement core values sothat they are present and meani

Development and Psychometric Exploration of the Anesthesia Surrendering Instrument (ASI)

PurposeThe aim of this study was to develop and test an instrument to measure surrendering at the time of anesthesia induction and to explore the construct validity.DesignAn instrumental cross-sectional design was used and construct validity was evaluated via psychometric testing.MethodsThe anesthesia surrendering instrument (ASI) comprised 36 items. A total of 202 adults (older than 18 years) ans

Magnetic resonance imaging techniques for evaluation of left ventricular function

Hjärtinfarkt är en av de vanligaste anledningarna till för tidig död. Vid en hjärtinfarkt dör delar av hjärtmuskeln på grund av att den utsätts för mycket kraftig syrebrist när ett kranskärl täpps till. Även hjärtmuskelvävnad i infarktens närhet påverkas. Hjärtats vänsterkammare förser kroppen med syresatt blod. Exakt hur vänsterkammarens funktion påverkas under de första dagarna efter hjärtinfark
