What Do We Know about Scientific Software Development's Agile Practices?

The development of scientific software has similarities with processes that follow the software engineering "agile manifesto": responsiveness to change and collaboration are of utmost importance. But how well do current scientific software-development processes match the practices found in agile development methods, and what are the effects of using agile practices in such processes?

Cyclic carbonates as monomers for phosgene- and isocyanate-free polyurethanes and polycarbonates

Polyurethanes and polycarbonates are widely used in a variety of applications including engineering, optical devices, and high-performance adhesives and coatings, etc., and are expected to find use also in the biomedical field owing to their biocompatibility and low toxicity. However, these polymers are currently produced using hazardous phosgene and isocyanates, which are derived from the reactio

Detailed theoretical and experimental description of normal Auger decay in O-2

The normal Auger electron spectrum of the O-2 molecule is assigned in detail on the basis of ab initio valence configuration interaction (CI) wavefunctions. Potential energy curves of the ground state, the core-ionized states and the doubly charged final states are calculated and Auger decay rates are obtained with the one-centre approximation. Using the lifetime vibrational interference method, b

Scholarly blogging practice as situated genre: an analytical framework based on genre theory

Introduction. Examines how an analytical framework of situated genre analysis can be used to study how research blogs are constructed and used as tools in scholarly communication. Method. A framework was extracted from genre research theories consisting of four concepts: aim, form, content and context. The term situated genre was used to focus on social practices. The context was further elaborate

Long-term Outcomes of Arthroscopic Acromioplasty for Chronic Shoulder Impingement Syndrome: A Prospective Cohort Study With a Minimum of 12 Years' Follow-up

Purpose: The Purpose of this Study was to evaluate long-term outcomes of arthroscopic acromioplasty for shoulder impingement syndrome. Methods: This was a prospective cohort study of 31 shoulders (24 men) that underwent arthroscopic acromioplasty for shoulder impingement syndrome during 1992 and 1993. The mean age at surgery was 49 years (range, 33 to 68 years). A group of 29 shoulders (22 men) op

Seasonal persistence of bumblebee populations is affected by landscape context

Bumblebee communities and their foraging resources were surveyed in south Swedish agricultural landscapes of contrasting complexity, defined by the size of arable fields and the amount of permanent grazed pastures. After the flowering of oilseed rape (OSR), simplified landscapes contained substantially less herbaceous flower resources and a lower proportion of perennials, compared to complex ones.

Numerical simulation of multi-scale transport processes and reactions in pem fuel cells using two-phase models

A numerical study for the cathode of a PEM fuel cell has been performed in this study. The results have been limited to cathode only because, in PEM fuel cells, the oxygen reduction reactions, ORRs, are considered the rate limiting reactions and govern the fuel cell performance. The modeling approach utilized the two-phase models involving water phase change for PEM fuel cells i.e. two-phase curr

Determinants of personal exposure to some carcinogenic substances and nitrogen dioxide among the general population in five Swedish cities

Environmental levels of airborne carcinogenic and related substances are comparatively better known than individual exposure and its determinants. We report on a personal monitoring program involving five Swedish urban populations. The aim of the program was to investigate personal exposure to benzene, 1,3-butadiene, formaldehyde, and nitrogen dioxide (NO2). The measurements were performed among 4

Changes of activity and isoforms of alkaline sphingomyelinase (nucleotide pyrophosphatase phosphodiesterase 7) in bile from patients undergoing endoscopic retrograde cholangiopancreatography.

Alkaline sphingomyelinase (NPP7) is an ecto-enzyme expressed in intestinal mucosa, which hydrolyses sphingomyelin (SM) to ceramide and inactivates platelet activating factor. It is also expressed in human liver and released in the bile. The enzyme may have anti-tumour and anti-inflammatory effects in colon and its levels are decreased in patients with colon cancer and ulcerative colitis. Active NP

How do children experience participating in a coeliac disease screening? A qualitative study based on children's written narratives

Aim: To explore how 12-year-old Swedish children experienced being involved in a coeliac disease (CD) screening. Methods: A qualitative approach was used to analyse short narratives written by children who had taken part in a school-based CD screening. Narratives were written after blood sampling, but prior to learning of the test results. Through an oscillation between the texts, codes, subcatego

High Transconductance, f(t) and f(max) in In0.63Ga0.37As FinFETs Using A Novel Fin Formation Technique

We report on In0.63Ga0.37As FinFETs utilizing nanowires grown by selective-area growth as channel. These nanowires are defined by crystallographic planes rather than pattern transfer using etching. The fabricated devices exhibit maximum transconductance g(m,max) = 2.05 mS/um at V-ds = 0.5 V, as well as record-high extrapolated f(t) = 300 GHz and f(max) = 342 GHz, on the non-planar III-V MOSFET pla

Finite element simulation of coating- induced heat transfer: application to thermal spraying processes

Thermal spraying is a widely applied coating technique. The optimisation of the thermal spraying process with respect to temperature or temperature induced residual stress states requires a numerical framework for the simulation of the coating itself as well as of the quenching procedure after the application of additional material. This work presents a finite element framework for the simulation

Gröbner Basis Approach to Some Combinatorial Problems

We consider several simple combinatorial problems and discuss different ways to express them using polynomial equations and try to describe the Gröbner basis of the corresponding ideals. The main instruments are complete symmetric polynomials that help to express different conditions in rather compact way.

Is Human Fear Affecting Public Willingness to Pay for the Management and Conservation of Large Carnivores?

From an interdisciplinary approach, this study aims at analyzing self-reported animal fear, specifically large carnivore fear, in relation to public willingness to pay to fulfill a governmental policy on large carnivore-induced costs. In a survey in Sweden involving more than 2,000 respondents, it was found that people whose animal fear was directed particularly toward large carnivores were less l

In Search of the Via Media between Christ and Marx: A Study of Bishop Ding Guangxun's Contextual Theology

This dissertation is the first academic treatment and systematic analysis on the theology of Bishop Ding Guangxun (K.H. Ding) who is an internationally- renowned Christian leader of the Chinese Protestant Church in contemporary China. It seeks to explore the development of Bishop Ding’s contextual theology with special emphasis on his political theology of accommodation and cultural indigenization

Sense of coherence and disability and the relationship with life satisfaction 6-15 years after traumatic brain injury in northern Sweden

The objective of the study was to assess sense of coherence (SOC) many years after traumatic brain injury (TBI) and explore the relationship between SOC and self-rated life satisfaction (LS) as well as measures of functioning and disability, sex, age at injury, injury severity and time post-injury. Sixty-six individuals (aged 18-65 years) who were 6-15 years post-injury were interviewed. Data on S
