Moodle som stöd för aktivt lärande

För att lära sig programmera måste studenterna själva vara aktiva och öva programmering på dator. Med ett omfattande kursinnehåll går det av resursskälinte att göra all nödvändig övning obligatorisk därför har vi digitaliserat övningsuppgifter som tidigare varit på papper i ett försök att få studenterna att göra fler övningar på med en mer aktiv approach.Försöken har mottagits väl och en majoritet

Att Märka Ord

Även om det är ytterst få av den undervisande personalen på Lunds tekniska högskola som medvetet skulle göra skillnad på kvinnliga respektive manliga studenter så förekommer det ändå. Det finns alltid en risk att undermedvetet ge fördelar/nackdelar av olika slag till olika grupper av studenter. För att undersöka detta gjordes en kvantitativ bedömning av kommunikationen mellan olika studentgrupper

Knowledge diversities and group dynamics within international master programs

Although international students are allowed to study at Swedish universities since 1985, the Swedish university landscape has undergone a strategic internationalization mainly during the recent few years. With a steadily growing number of international master programs and thereby more international students being part of the Swedish education system, a variety of problems related to cultural-diver

Distribuerad kurs- och ämnesutveckling

Läsåret 2013/14 skulle grundkursen i kemisk reaktionsteknik vid LTH omarbetas. Kontakt togs med lärare på Chalmers för att diskutera deras erfarenheter av undervisning i ämnet och den lärobok som var i åtanke för den nya kursen. Diskussionen ledde fram till ett konkret samarbete genom att vi beslöt att skapa en gemensam mapp för undervisningsmaterial på "molntjänsten" Box. Under det senaste läsåre

Diffusion tensor MRI to distinguish progressive supranuclear palsy from a-synucleinopathies

Background: The differential diagnosis of progressive supranuclear palsy (PSP) and Lewy body disorders, which include Parkinson disease and dementia with Lewy bodies, is often challenging due to the overlapping symptoms. Purpose: To develop a diagnostic tool based on diffusion tensor imaging (DTI) to distinguish between PSP and Lewy body disorders at the individual-subject level. Materials and Met

Evidence of New Particle Formation Within Etna and Stromboli Volcanic Plumes and Its Parameterization From Airborne In Situ Measurements

Volcanic emissions can significantly affect the Earth's radiation budget by emitting aerosol particles and gas-phase species that can result in the new particle formation (NPF). These particles can scatter solar radiation or modify cloud properties, with consequences on health, weather, and climate. To our knowledge, this is the first dedicated study detailing how gas-phase precursors emitted from

Strain improvement of Escherichia coli K-12 for recombinant production of deuterated proteins

Deuterium isotope labelling is important for structural biology methods such as neutron protein crystallography, nuclear magnetic resonance and small angle neutron scattering studies of proteins. Deuterium is a natural low abundance stable hydrogen isotope that in high concentrations negatively affect growth of cells. The generation time for Escherichia coli K-12 in deuterated medium is substantia

Developing a framework for characterising cascading failures in past events to inform emergency response decisions

Increasing interdependencies between critical infrastructures have made these systems more effective, but also more susceptible to cascading failures. In order to reduce the likelihood and consequences of cascading failures, it is essential to develop tools that support incident commander decisions so that an initial failure does not spread to other infrastructures. Here, a framework for generatin

Identification of the intermediate filament protein synemin/SYNM as a target of myocardin family coactivators

Myocardin (MYOCD) is a critical regulator of smooth muscle cell (SMC) differentiation, but its transcriptional targets remain to be exhaustively characterized, especially at the protein level. Here we leveraged human RNA and protein expression data to identify novel potential MYOCD targets. Using correlation analyses we found several targets that we could confirm at the protein level, including SO

Ensemble Green's function theory for interacting electrons with degenerate ground states

An ensemble Green's function formalism, based on the von Neumann density matrix approach, to calculate one-electron excitation spectra of a many-electron system with degenerate ground states is proposed. A set of iterative equations for the ensemble Green's function and self-energy is derived and a simplest approximation corresponding to an ensemble GW approximation is naturally obtained. The deri

Polyelectrolyte-nanoplatelet complexation : Is it possible to predict the state diagram?

The addition of polyelectrolytes (PEs) to suspensions of charged colloids, such as nanoplatelets (NPs), is of great interest due to their specific feature of being either a stabilizing or a destabilizing agent. Here, the complexation between a PE and oppositely charged NPs is studied utilizing coarse-grained molecular dynamics simulations based on the continuum model. The complex formation is eval

Disentangling the Environmental Factors That Shape Genetic and Phenotypic Leaf Trait Variation in the Tree Qualea grandiflora Across the Brazilian Savanna

Identifying the environmental factors that shape intraspecific genetic and phenotypic diversity of species can provide insights into the processes that generate and maintain divergence in highly diverse biomes such as the savannas of the Neotropics. Here, we sampled Qualea grandiflora, the most widely distributed tree species in the Cerrado, a large Neotropical savanna. We analyzed genetic variati

Defying hard-to-heal wounds with an early antibiofilm intervention strategy : 'Wound hygiene'

Biofilm has been implicated as a barrier to wound healing and it is widely accepted that the majority of wounds not following a normal healing trajectory contain biofilm. Therefore, strategies that inform and engage clinicians to reduce biofilm and optimise the wound tissue environment to enable wound progression are of interest to wound care providers. In March 2019, an advisory board was convene

Examining practice effects in repeated measurements of vibration perception thresholds on finger pulps of healthy individuals – Is it possible to improve your results over a clinically relevant test interval?

Aims To investigate practice effects in a test-retest situation, where vibration perception thresholds (VPT) were measured in healthy subjects using a multi-frequency test method. Methods In eight consecutive tests, VPTs were tested in the pulps of the index and little fingers at seven frequencies (8, 16, 32, 64, 125, 250 and 500 Hz). Subjects were twenty healthy adults aged 26 to 65 years (mean 4

Magnetic Guinier law

Small-angle scattering of X-rays and neutrons is a routine method for the determination of nanoparticle sizes. The so-called Guinier law represents the low-q approximation for the small-angle scattering curve from an assembly of particles. The Guinier law has originally been derived for nonmagnetic particle-matrix-type systems and it is successfully employed for the estimation of particle sizes in

Private Bank Money vs Central Bank Money: A Historical Lesson for CBDC Introduction

In this paper, a unique event is studied: the opening of Bank of Canada in 1935, the central bank note issuance monopoly and its impact on the note issuing chartered banks. Between 1935-1950, Canadian chartered banks had to gradually withdraw their notes from circulation. In a difference-in-differences analysis, I show that chartered banks constrained by new issuance limits experienced higher vola

Determinants of Wealth Inequality and Mobility in General Equilibrium

What determines inequality and mobility of wealth? This paper quantifies in closed form both the bottom and the top (Pareto) tail of the distribution for a rich continuous-time model. The distribution is especially shaped by bequest motives, demographics, and the asset portfolio composition under idiosyncratic wealth risk. Factors that increase inequality also reduce mobility. The model - enriched
