QREME – Quality requirements management model for supporting decision-making

[Context and motivation] Quality requirements (QRs) are inherently difficult to manage as they are often subjective, context-dependent and hard to fully grasp by various stakeholders. Furthermore, there are many sources that can provide input on important QRs and suitable levels. Responding timely to customer needs and realizing them in product portfolio and product scope decisions remain the main

The importance of gender roles and relations in rural agricultural technology development : a case study on solar fruit drying in Mozambique

Many agricultural technology interventions that aim to improve farmers’ livelihoods focus on households as the unit of analysis and ignore gender roles that entail different benefits and costs for different household members. Agricultural projects have shown limited success where gender roles and relations were ignored and thus more gender sensitive research is needed in agricultural technology de

Knowledge management in software testing : A systematic snowball literature review

Background: Software testing benefits from the usage of Knowledge Management (KM) methods and principles. Thus, there is a need to adopt KM to the software testing core processes and attain the benefits that it provides in terms of cost, quality, etc. Aim: To investigate the usage and implementation of KM for software testing. The major objectives include 1. To identify various software testing as

Abstract [Bryophyes in base-rich fens in Skåne, southern-most Sweden, now and in the past] Over the last centuries, due to the combined effects of drainage, cultivation, eutrophication and overgrowth, the majority of all tree-less base-rich fens that were once found in Skåne have been lost and the typical species of these habitats have suffered accordingly. Here, the past and present distribution Abstract [Bryophyes in base-rich fens in Skåne, southern-most Sweden, now and in the past] Over the last centuries, due to the combined effects of drainage, cultivation, eutrophication and overgrowth, the majority of all tree-less base-rich fens that were once found in Skåne have been lost and the typical species of these habitats have suffered accordingly.

The benefits that (only) capital can see? Resource access and degradation in industrial carbon forestry, lessons from the CDM in Uganda

Recent research has shed light on the various tradeoffs involved in carbon forestry, i.e. the pursuit of international forestry projects to help mitigate climate change. This article contributes to these debates by highlighting the importance of resource quality and degradation in evaluating project benefits and tradeoffs. Focusing on the case of an industrial tree plantation in Uganda, the Kachun

α-Synuclein Fibril Formation and the Effects of Lipid Membranes

Amyloid protein aggregation results in major disturbances of cellular processes in humans. The most common amyloid-related disorders are Alzheimer´s disease and Parkinson´s disease. Parkinson´s disease is charaterized by the formation of protein-rich aggregates that are deposited in neurons, termed Lewy bodies and Lewy neurites. The main component identified in these protein-rich deposits is the pAmyloid protein aggregation results in major disturbances of cellular processes in humans.

Measurement of charged-particle distributions sensitive to the underlying event in √s=13 TeV proton-proton collisions with the ATLAS detector at the LHC

We present charged-particle distributions sensitive to the underlying event, measured by the ATLAS detector in proton-proton collisions at a centre-of-mass energy of 13 TeV, in low-luminosity Large Hadron Collider fills corresponding to an integrated luminosity of 1.6 nb−1. The distributions were constructed using charged particles with absolute pseudorapidity less than 2.5 and with transverse mom

Search for anomalous electroweak production of WW /WZ in association with a high-mass dijet system in pp collisions at s =8 TeV with the ATLAS detector

A search is presented for anomalous quartic gauge boson couplings in vector-boson scattering. The data for the analysis correspond to 20.2 fb-1 of s=8 TeV pp collisions and were collected in 1972 by the ATLAS experiment at the Large Hadron Collider. The search looks for the production of WW or WZ boson pairs accompanied by a high-mass dijet system, with one W decaying leptonically and a W or Z dec

Measurements of ψ(2S) and X(3872) → J/ψπ + π − production in pp collisions at √s=8 TeV with the ATLAS detector

Differential cross sections are presented for the prompt and non-prompt production of the hidden-charm states X(3872) and ψ(2S), in the decay mode J/ψπ+π−, measured using 11.4 fb−1 of pp collisions at s=8 TeV by the ATLAS detector at the LHC. The ratio of cross-sections X(3872)/ψ(2S) is also given, separately for prompt and non-prompt components, as well as the non-prompt fractions of X(3872) and

On the taut string interpretation of the one-dimensional rudin–osher–fatemi model

A new proof of the equivalence of the Taut String Algorithm and the one-dimensional Rudin–Osher–Fatemi model is presented. Based on duality and the projection theorem in Hilbert space, the proof is strictly elementary. Existence and uniqueness of solutions (in the continuous case) to both denoising models follow as by-products. The standard convergence properties of the denoised signal, as the reg

Activin receptor-like kinase 1 is associated with immune cell infiltration and regulates CLEC14A transcription in cancer

Cancer cells sustain their metabolic needs through nutrients and oxygen supplied by the bloodstream. The requirement for tumor angiogenesis has been therapeutically exploited in the clinical setting mainly by means of inhibition of the vascular endothelial growth factor family of ligands and receptors. Despite promising results in preclinical models, the benefits for patients proved to be limited.

Nätkritiken utmanar censuren

På kort tid har Kina fått över 300 miljoner mikro­bloggare. På nätet sprids förutom skvaller och rykten även skarp kritik mot kommunistpartiet. Den kinesiska staten har fått en utmanare i kampen om informationen.

EPS production by Propionibacterium freudenreichii facilitates its immobilization for propionic acid production

Aims: Immobilization of microbial cells is a useful strategy for developing high cell density bioreactors with improved stability and productivity for production of different chemicals. Functionalization of the immobilization matrix or biofilm forming property of some strains has been utilized for achieving cell attachment. The aim of the present study was to investigate the production of exopolys

Nuytsia floribunda – sydvästra Australiens unika mistelträd och dess upptäckthistoria

Nuytsia floribunda, was first described in print by Jacques Labillardière in a work from 1805 – Novae Hollandiae Plantarum Specimen – under the name of Loranthus floribundus. The name aimed at describing the colorful flowering, on a tree unique in the plant world through its hemiparastic way of living, developing of haustoria not seen elsewhere. Labillardière had observed the species on a journey

Literature review of flexibility attributes : A flexibility framework for software developing organization

Software developing organizations strive to achieve flexibility to maintain a competitive advantage. There is no common understanding of what characterize flexibility for a software organization beyond the scope of the software product. Without a common understanding, it is difficult to evaluate the degrees of flexibility of software development approaches. The aim of this literature review is to

Replicate or alternate? Isotropic boundary conditions and implications for Ewald summation

Periodic boundary conditions (PBC) are well suited to describe repetitive structures in space, yet flawed for isotropic setups in which it is commonly used. We present an approach based on exploiting the congruency of a unit cell which combines the periodic nature of PBC with isotropy of an alternating cell. By applying these isotropic periodic boundary conditions (IPBC) to the standard Ewald summ

Speed reduction effects over distance of animal-vehicle collision countermeasures – a driving simulator study

Purpose: This study examined if speed reduction effects from animal-vehicle collision (AVC) countermeasures are merely local or do extend to a wider area, and what implications the results have on road planning practice regarding AVCs. Methods: Twenty-five drivers drove repeatedly on a 9-km long road stretch in a high-fidelity driving simulator. The development of vehicle speed in the surrounding
