Requirements engineering for market-driven software development entails special challenges. This paper presents results from an empirical study that investigates these challenges, taking a qualitative approach using interviews with fourteen employees at eight software companies and a focus group meeting with practitioners. The objective of the study is to increase the understanding of the area of

Fungal (acetate-in-ergosterol incorporation) and bacterial (leucine/thymidine incorporation) growth resulting from alfalfa (C/N = 15) and barley straw (C/N = 75) addition was studied in soil microcosms for 64 days. Nitrogen amendments were used to compensate for the C/N difference between the substrates. Fungal growth increased to a maximum after 3–7 days, at five to eight times the controls, foll

Site I of antigenic domain 2 (AD-2) on human cytomegalovirus glycoprotein B (gB) is poorly immunogenic in both man and mouse and knowledge about antibody repertoires reactive with this epitope is thus limited. Here we have characterized a phage display-derived repertoire of antibody fragments specific for this epitope in terms of antigen recognition, fine-specificity, and virus-neutralizing capaci

Popular Abstract in Swedish I denna avhandling analyseras unga mäns vålds- och offerupplevelser. Studien bygger på olika typer av material men det mest centrala underlaget består av samtalsintervjuer med unga män som har blivit utsatta för misshandel eller rån. Sätten på vilka de unga männen talar om sig själva, förövaren, våld och offerskap utgör utgångspunkten för analysen. Inom ramen för samtalIn this dissertation, young men's experiences of being victims of crime are analysed. Several kinds of material are considered in this study, but the primary data consist of informal, tape-recorded interviews with ten young men (17 to 21 year's old) who had been assaulted or mugged. Their accounts of their experiences are analysed using a number of constructionist, interactionist, and narrative pe

The RISING (Rare ISotope INvestigations at GSI) project constitutes a major pan-european initiative to study nuclear structure in exotic nuclei. A brief outline of the technical details specific to studies of isomeric decays following relativistic projectile fragmentation reactions is presented.

Context: Testis development is a tightly regulated process that requires an efficient and coordinated spatiotemporal action of many factors, and it has been shown that several genes involved in gonadal development exert a dosage effect. Chromosomal imbalances have been reported in several patients presenting with gonadal dysgenesis as part of severe dysmorphic phenotypes. Results: We screened for

A synthetic polymer selective for (S)-naproxen was prepared by molecular imprinting. 4-Vinylpyridine and ethylene glycol dimethacrylate were copolymerised in the presence of the template, (S)-naproxen. The template was extracted from the polymer, leaving specific recognition sites, complementary to the template. The polymer was utilized as a stationary phase in HPLC. Racemic naproxen was efficient

In this paper we investigate the structure and motion problem for calibrated one-dimensional projections of a two-dimensional environment. The theory of one-dimensional cameras are useful in several areas, e.g. within robotics, autonomous guided vehicles, projection of lines in ordinary vision and vision of vehicles undergoing so called planar motion. In a previous paper the structure and motion p

Mutual coupling effects between antenna elements on signal correlation are reported. A simple expression is derived to compute the correlation coefficient from the far-field radiation patterns including the characteristics of the propagation environment and the terminating impedance. It is shown that the mutual coupling between closely spatially separated dipoles call lead to increased signal deco

Aims: This study examined whether middle-aged men exhibiting markers of early ageing showed a different pattern of social factors, lifestyle, and biological variables compared with controls, and whether early ageing was associated with an increased mortality risk. Subjects and methods: We used a subgroup of 5,722 middle-aged men (mean age 47 years), investigated twice, from the Malmö Preventive Pr

We investigated whether dorsal hindbrain and/or peripheral cocaine- and amphetamine-regulated transcript peptide (CARTp) acts to suppress gastric emptying of a caloric stimulus. Furthermore, effects of dorsal hindbrain CARTp on sucrose consumption and licking microstructure was studied, as well as the possible contribution of corticotropin-releasing factor (CRF) receptors to mediate effects of CAR

We prove a general atomic decomposition theorem for weighted vector-valued Bergman spaces, which applies to duality problems and to the study of compact Toeplitz type operators.
