This thesis work is concerned with the efficient layout and operation of substations, i.e. those district heating (DH) system units which connect the network and internal building heating systems, such as radiator heating systems and domestic hot water distribution networks. The ambition was to make realistic investigations closely related to practical technologies within the field. The themes of

Background The aim of the Nordic Diltiazem (NORDIL) Study was to compare patients with essential hypertension receiving calcium-antagonist-based treatment with diltiazem and similar patients receiving conventional diuretic/beta-blocker-based treatment, with respect to cardiovascular morbidity and mortality. Objective To assess the influence of age, sex, severity of hypertension and heart rate on t

En fältstudie på åtta mastarbetare utfördes under februari i Svealand och Norrland. Mastarbetarnas aktiviteter observerades under en vanlig arbetsdag i masten och hudtemperaturen på sju ställen på kroppen, kroppstemperatur och hjärtfrekvens registrerades kontinuerligt. De fick också skatta sin temperaturupplevelse och ansträngningsgrad flera gånger under dagen. Lufttemperaturen varierade mellan -1

Architects design work sometimes originates from a simplified view of human demands and needs, which may result in environments that do not fulfill the users requirements. This thesis refers to five different case studies where the affected users were involved in the creation of their dwellings or working environment. The issue of the thesis is that participatory design creates environments which

The principal fate during litter decomposition and mineralization is rather well established only for a limited number of elements, mainly essential plant nutrients and a few potentially very toxic metals. Elements which occupy the majority of the positions in the periodical system seems almost unknown in this context. The objectives were, therefore to assess differences in the behavior of 58 mine

The thesis is a broad attempt to analyse economic forces behind, and economic rationales for, institutions that constrain the organisation and operation of insurance companies. The basic task is threefold: (i) to develop institutional theory by providing an outline of a transaction cost explanation of the origin of, and the rationale for, institutions that constrain the organisation and the operat

Thisthesis revisits and explores the relationship between verse and meaning bymeans of the notion of iconicity, i.e.,as signs primarily based on similarity. The aim of the thesis is to show howverse and its interaction with words and sentences create meaning and can be anintegrated part in the interpretation or understanding of the poem as a whole.Verse is discussed in relation to four other liter

Addressing sustainability concerns in supply chain operations can be a matter of long-term business survival for food retailers. However, regardless of whether it is perceived as a risk or market opportunity, acting across the value chain to address unsustainable production and consumption practices has been a constant challenge. This thesis investigated the sustainable supply chain management (SS

The characterization of naturally occurring mutations is one way to approach functionally significant domains of polypeptides. About 10 mutations have been reported in factor XIII (FXIII) A-subunit deficiency, but very little is known about the effects of the mutations on the expression or the structure of this enzyme. In this study, the recent crystallization of FXIII A-subunit and determination

Diet-breast cancer studies have shown that “healthy eating patterns” are associated with decreased risk whereas unhealthy patterns (especially those including alcohol) are associated with increased risk, particularly in postmenopausal women. The potential mechanisms behind the observed associations are still under investigation. A great deal of evidence supports the major role of lifelong overexpo

BACKGROUND: Interactive behavior change technology (eg, computer programs, Internet websites, and mobile phones) may facilitate the implementation of lifestyle behavior interventions in routine primary health care. Effective, fully automated solutions not involving primary health care staff may offer low-cost support for behavior change. OBJECTIVES: We explored the effectiveness of an electronic

Aims: During recent years, two strategies of incretin-based therapy [glucagon-like peptide-1 (GLP-1) receptor agonism and dipeptidyl peptidase-4 (DPP-4) inhibition] have entered the market for pharmacological management of type 2 diabetes. A main indication for this therapy is as add-on to on-going metformin therapy in subjects with type 2 diabetes who have insufficient glycaemic control with metf
