Software Quality Across Borders: Three Case Studies on Company Internal Alignment

Context Software quality issues are commonly reported when offshoring software development. Value-based software engineering addresses this by ensuring key stakeholders have a common understanding of quality. Objective This work seeks to understand the levels of alignment between key stakeholder groups within a company on the priority given to aspects of software quality developed as part of an

Antitreponemal Antibodies Leading to Autoantibody Production and Protection from Atherosclerosis in Kitavans from Papua New Guinea

The objective of our study was to determine the prevalence of anti-infectious agent antibodies and autoantibodies in a unique non-Westernized population from Kitava, Papua New Guinea (PNG), compared to Western populations. We matched 120 serum samples from Kitavans with 437 samples from four healthy control groups. Sera were tested for the presence of anti-infectious agent antibodies (treponema, t

Unraveling the similarity of the photoabsorption of deprotonated p-coumaric acid in the gas phase and within the photoactive yellow protein

Using advanced QM/MM methods, the surprisingly negligible shift of the lowest-lying bright electronic excitation of the deprotonated p-coumaric acid (pCA(-)) within the photoactive yellow protein (PYP) is shown to stem from a subtle balance between hypsochromic and bathochromic effects. More specifically, it is found that the change in the excitation energy as a consequence of the disruption of th

Response actions to difficulties in using everyday technology after acquired brain injury

Purpose: People with acquired brain injury (ABI) have difficulties using everyday technology (ET) in daily tasks at home and in society. To support them in managing the demands imposed by using ET, knowledge is needed concerning their response actions to the difficulties. The aim of this study was to explore and describe what characterizes response actions to difficulties using ET, their condition

Spectral characterization of diffusion with chemical shift resolution: Highly concentrated water-in-oil emulsion.

We present a modulated gradient spin-echo method, which uses a train of sinusoidally shaped gradient pulses separated by 180 degrees radio-frequency (RF) pulses. The RF pulses efficiently refocus chemical shifts and de-phasing due to susceptibility differences, resulting in undistorted, high-resolution diffusion weighted spectra. This allows for the simultaneous spectral characterization of the di

Muesli with 4g oat beta-glucans lowers glucose and insulin responses after a bread meal in healty subjects

Objective: To evaluate the impact of an extruded muesli product based on -glucan-rich oat bran on postprandial glycaemia and insulinaemia. Subject/Design: The study is divided in two series. Blood glucose and serum insulin responses were studied after subjects consuming test meals including a serving of muesli with 3 g (series 1) and 4 g (series 2) of -glucans, respectively. The muesli was a comp

Education reform in Bolivia : Transitions toward which future?

This article concerns the impact of educational reforms on young people in Bolivian society as they transition into adulthood, against the backdrop of globalisation and far-reaching structural changes. Ethnicity and cultural capital are linked in complex ways with social stratification in Bolivia. In a pluricultural society, the language of instruction and curricular content are among the most fun

Dielectric Interpretation of Specificity of Ion Pairing in Water

We present a dielectric continuum model that, at a semiquantitative level, explains why ion pair formation in water is favored by like-sized ions over unlike-sized pairs. Using both classical and ab initio continuum approaches, we show that the now well-established empirical rule, the so-called “law of matching water affinities”, can be rationalized in terms of ion solvation. Namely, pairing of di

Self- healing of cracks in concrete long-term exposed to different types of water : results after 1 year exposure

SUMMARY The aim of the project was to find out if cracks in concrete exposed to water can heal so that chloride ingress in the crack is effectively obstructed. If this is the case it might be possible to accept wider cracks in concrete than is allowed today. 18 concrete specimens with induced cracks, 0.2 and 0.4 mm wide, were exposed to sea water, brackish water and tap water for 1 year. For most

Xinyi Jiang - en experimentell etnograf från Shanghai

In a master thesis on food waste the importance of culturally defined behaviour is addressed. By constructing a "Food Waste Game", experimental ethnographer Xinyi Jiang show how definitions of what can be considered as food waste change. The Food Waste Game give evidence to sorting by association, meaning that packaging of different materials is considered to be food waste.

Retrofitting Conventional Electric Domestic Hot Water Heaters to Solar Water Heating Systems in Single-Family Houses-Model Validation and Optimization

System cost reductions and development of standardised plug-and-function systems are some of the most important goals for solar heating technology development. Retrofitting hot water boilers in single-family houses when installing solar collectors has the potential to significantly reduce both material and installation costs. In this study, the TRNSYS simulation models of the retrofitting solar th

Differential Dopamine Receptor Occupancy Underlies L-DOPA-Induced Dyskinesia in a Rat Model of Parkinson's Disease.

Dyskinesia is a major side effect of an otherwise effective L-DOPA treatment in Parkinson's patients. The prevailing view for the underlying presynaptic mechanism of L-DOPA-induced dyskinesia (LID) suggests that surges in dopamine (DA) via uncontrolled release from serotonergic terminals results in abnormally high level of extracellular striatal dopamine. Here we used high-sensitivity online micro

Particulate PAH Emissions from Residential Biomass Combustion: Time-Resolved Analysis with Aerosol Mass Spectrometry

Time-resolved emissions of particulate polycyclic aromatic hydrocarbons (PAHs) and total organic particulate matter (OA) from a wood log stove and an adjusted pellet stove were investigated with high-resolution time-of-flight aerosol mass spectrometry (ANIS). The highest OA emissions were found during the addition of log wood on glowing embers, that is, slow burning pyrolysis conditions. These emi

Versatile multispectral microscope based on light emitting diodes.

We describe the development of a novel multispectral microscope, based on light-emitting diodes, capable of acquiring megapixel images in thirteen spectral bands from the ultraviolet to the near infrared. The system captures images and spectra in transmittance, reflectance, and scattering modes. We present as examples of applications ground truth measurements for remote sensing and parasitology di

A longitudinal study of the working relationship and return to work: perceptions by clients and occupational therapists in primary health care.

The working relationship between client and therapist can be important to enhance outcomes from vocational rehabilitation for women with stress-related disorders in primary health care. The aim was to investigate the working relationship, as perceived by clients and therapists in the Redesigning Daily Occupations (ReDO™) program, and its relationships to return to work and satisfaction with the re
