In this study full-scale experiments with two different conventional cooling-coils aimed for display cabinets were performed. Heat transfer and pressure drop on the liquid side for three different single phase secondary refrigerants were studied and compared to predictions by existing correlations. Predominantly, the laminar flow regime was studied. The results show that when predicting the heat t

Memorials wanted: A call for information on memorials in Denmark, where archaeological finds have been discovered.

Electricity has been regarded as a typical example of a general purpose technology and important for the surge both in energy productivity and overall productivity in the American economy in the 1920s. This view was challenged by Nicholas and Moser (2004) based on patent statistics. We argue that other methods are required for studying productivity effects and propose cointegration analyses. We de

Popular Abstract in Swedish Denna avhandling analyserar frågor som berör tillfälliga jobb på den svenska arbetsmarknaden under perioden 1990-1999. Ett viktigt bidrag i avhandlingen är att den stora gruppen tillfälliga jobb delas upp i mindre undergrupper för att ta i beaktande den heterogenitet som finns mellan olika former av tillfälliga jobb. En röd tråd som löper genom hela avhandlingen är fokuThis thesis analyses different aspects of temporary jobs in the Swedish labour market during 1991-1999. Throughout the thesis we put special focus on differences between the genders, and differences between native-born and foreign-born workers. In chapter 1, An Introduction to Temporary Jobs in Sweden, we describe the evolution of different types of temporary jobs in Sweden during the 1990s, we re

Freud´s 1921/1922 essay "Group psychology and the analysis of the Ego" is reviewed in light of Freud´s influence by LeBon, McDougall and Trotter. The cultural climat in post-war Europe and it´s pessimism is also demonstrated as a contributing factor to Freud´s view on groups and massses. Th influence of the essay on subsequent group resaerch is demonstrated and discussed.

The aim of this study is to analyse the total use of energy in four multi-family houses during their life cycles, and to compare the use of energy during the different periods in the life cycle. The aim is also to investigate how energy use during the life cycle changes with different construction parts, e g if the thermal insulation thickness or the framework is changed. Results show that the en

Element cycling and nutrient supply in forest ecosystems are of vital importance for short-term productivity and for longer-term land management in terms of nutrient leaching and CO2 fixation. This thesis includes a series of studies with the objective of modelling some aspects of the effect of acidification and climate change on element cycling and nutrient supply in forest soil. A reconstructio

The cerebral ischemia that occur after a subarachnoid hemorrhage (SAH) often results in death or severe disability and is a significant cause of stroke. Our hypothesis is that cerebral ischemia leads to pathophysiological receptor changes on the vascular smooth muscle cells. The changes may lead to a stronger vasoconstriction than normal in response to endogenous ligands. We are focusing on the en

A common control technique for limiting nitrogen oxide emissions is selective catalytic reduction (SCR) of NO, with NH,. The lifetime of the catalyst, which has a critical role in overall SCR system economics, is, however, limited due to deactivation by poisoning. A two-dimensional model was developed to describe poison accumulation and activity of an SCR catalyst. The model that has no adjustable

In an investigation conducted by the Swedish Cancer Society. the present status, critical issues and future aspects and potentials were described by expert group for each of nine major areas of radiation therapy research. In this report, research and development in radiation therapy clinical routines is described. The terms research, development, quality assurance, quality control and clinical rou

This paper treets the acquisition, variation and historical change in the use of the article with kinship names in Italian, or more precisely, the Florentine variety of Italian. The development in acquisition data and historical texts is compared regarding the use of the definitive article together with kinship nouns. The children studied in this paper classify DPs in non-target-like ways apparent

Artikel om kritiken av Lunds universitets studentdatorprojekt från utvärderaren Conny Svenning.

Popular Abstract in Swedish Vad är ett orsakssamband? Och vad är en orsak? Författaren hävdar att orsakssamband är lika verkliga och lokala som dess orsaker och effekter. Denna position är diametralt motsatt synen att orsakssamband i den mån de alls kan sägas finnas är instanser av lagbundenheter; en syn som (med viss orätt) tillskrivs David Hume, och som sedan dennes Treatise (1739) under långa tThe thesis addresses the nature of causation. It is argued that causation exists and is as local as its causes and effects. As a consequence, the position advocated is contrary to the as yet prevailing view that no 'causal tie' between cause and effect exists. Moreover, it is suggested that this tie can be perceived. The essay attempts to elucidate the nature of causes, effects, and causal mechani
