Purpose – This paper aims to discuss a new tool for requirements gathering in the Web 2.0 era. It seeks to investigate the features that this kind of tool should have in order to be as widely applicable and useful as possible. Further, it aims to explore the extent to which business requirements for enterprise resource planning (ERP) systems can be collected and discussed collaboratively in a worl

The major part of the Swedish hydro power development took place between 1945 and 1975. At that point of time, significant progress had been made regarding the use of high quality concrete for hydraulic structures. In spite of the progress made, deterioration of concrete due to freezing and thawing is still frequent. Superficial damage at the waterline and spalling of concrete far below the water

Popular Abstract in Swedish Melanin är ett pigment som finns i många olika slags vävnader. I hud och hår finns två slags melanin, pheomelanin som är typiskt för rödhåriga personer och eumelanin som finns i större mängd i mörkt hår och hud. Konstaterad korrelation mellan hudcancer och solexponering motiverar forskarna att förstå mer om melanin och dess växelverkan med UV-ljus. Man vet att rödhårigaMelanin is an epidermal pigment commonly known to give darker skin coloration under sun exposure. It is also present in the hair, eyes, inner ear and brain. The first function of epidermis melanin is believed to be photoprotective against harmful ultraviolet (UV) light, but the recent increase of skin cancer correlated to an increase of sun exposure questions the properties of melanin. Its presenc

In this contribution we study the balloon angioplasty in a residually stressed artery by means of a non-local gradient-enhanced fibre damage model. The balloon angioplasty is a common surgical intervention used to extend or reopen narrowed blood vessels in order to restore the continuous blood flow in, for instance, atherosclerotic arteries. Inelastic, i.e. predominantly damage-related and elastop

This article studies the Kyoto Protocol’s CDM as an example of hybrid governance, involving both public and private actors, and uses the concept of agency to explore the influence of public and private actors in the governance of the CDM over time. Even though public actors formally govern the CDM, the delegation of project implementation and supervision to private companies has created ample oppo

Poly(d,l-lactic-co-glycolic acid) (PLGA) is the most frequently used biodegradable polymer in the controlled release of encapsulated drugs. Understanding the release mechanisms, as well as which factors that affect drug release, is important in order to be able to modify drug release. Drug release from PLGA-based drug delivery systems is however complex. This review focuses on release mechanisms,

Many ICU-patients have memory-gaps which may affect their recovery. A tool in the recovery can be an ICU-diary to explain and clarify thoughts and events from the ICU-period. There are different standards for the content in the ICU-diary. The aim of this study was to identify the preferred content and usefulness of an ICU-diary as described by ICU-patients. METHOD: A descriptive, exploratory co

I denna artikel har jag försökt visa att när man engagerar sig i en politisk rörelse spelar emotioner en inte obetydlig roll. Ty den fråga man måste ställa sig är om det är troligt att känslorna inte har någon betydelse för de personer som är aktiva i föreningar av olika slag? Tron att passion och emotioner har en betydelse för engagemanget kan ses som ett alternativ till uppfattning att det är ”i

The authoritarian Ba?th regime in power in Syria since 1966 has been challenged twice by popular contention. In the first case, ?The Islamic rebellion?, the episode of contention erupted into violence, in the second case, ?The Damascus Spring?, it did not. In both cases the challengers changed strategies and methods of contention adapting to their counterparts and the external environment. This s

The irritation response of the rabbit eye to trigeminal nerve stimulation, which includes a breakdown of the blood-aqueous barrier (BAB), seems to be due to the release of substance P (SP) and calcitonin gene-related peptide (CGRP). In order to assess the relative importance of these two peptides for the barrier effect, and the role of arachidonic acid metabolites (AAM) in the response, we have st

The current ambition to enlarge the European Union (EU) from fifteen to twenty-seven member states has brought to the fore questions about European integration and its overarching aim. On 7 June, 2001, the Irish people decided not to ratify the Nice Treaty. However, the Irish 'no' was not considered to be an expression of political resentment that could impinge on further development of European i

Various Helicobacter species have been isolated from the stomach, intestinal tract and liver of a variety of mammalian and some avian species, and Helicobacter DNA has been detected in human bile and liver samples. An immunoblot assay was established to analyse serum antibody responses to non-gastric Helicobacter species in patients with autoimmune liver diseases, in comparison with healthy indivi

Popular Abstract in Swedish I början 1990-talet upptäcktes att det var möjligt att syntetisera så kallad mesoporös silika. Upptäckten fick stor uppmärksamhet då materialen har ett flertal intressanta egenskaper som inkluderar ett stort antal porer med väldefinierad diameter, jämn partikelstorlek och möjligheten att påverka dessa och andra egenskaper. I den här avhandlingen har det mesoporösa siliSeveral aspects related to the mesoporous silica material SBA-15 have been studied through the use of a wide range of experimental techniques, including low voltage high-resolution scanning electron microscopy, small angle X-ray scattering and nitrogen sorption. This work contains three parts, which are in many ways overlapping. The first part deals with the formation of SBA-15, it is found that a

In the emerging Delay Tolerant Networks (DTNs) content dissemination platform, mobile nodes opportunistically exchange content as they meet, with the intent of sharing content among nodes with common interests. During a meeting, nodes can exchange both content of direct interest to themselves as well as content that is of interest to a larger set of nodes that may be encountered in the future. The

Popular Abstract in English The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes. WrbA has a catalytic FMN-containing The catalytic and electrochemical properties of tryptophan repressor-binding protein (WrbA), pyranose dehydrogenase (PDH), cellobiose dehydrogenase (CDH) and glucose dehydrogenase (GDH) on carbon electrodes were investigated using cyclic voltammetry and flow injection amperometry to construct biosensors and biofuel cell (BFC) anodes.
