Spaceship Earth : när civilisationskritiken möter ekonomivetenskapen

År 1966 publicerade den amerikanske ekonomen Kenneth E. Boulding (1910–1993) sin inflytelserika essä ”The Economics of the Coming Spaceship Earth” med ett budskap som skulle landa mitt i en politisk omvälvningsfas, där civilisationskritiska perspektiv skulle låta göra sig alltmer gällande. Bouldings essä är en föregångare till dagens miljödiskussion.

An atrioventricular node model incorporating autonomic tone

The response to atrial fibrillation (AF) treatment is differing widely among patients, and a better understanding of the factors that contribute to these differences is needed. One important factor may be differences in the autonomic nervous system (ANS) activity. The atrioventricular (AV) node plays an important role during AF in modulating heart rate. To study the effect of the ANS-induced activ

Uniqueness and similarity in flame propagation of pre-dissociated NH3 + air and NH3 + H2 + air mixtures : An experimental and modelling study

Ammonia (NH3) has attracted significant attention as a promising hydrogen carrier and a carbon-free alternative fuel. Partial dissociation could convert part of ammonia to H2 and N2 before injecting the fuel into a combustor, thus overcoming the low reactivity and high NOx emission problems during the NH3 combustion. The pre-dissociated NH3 + air mixture has unburnt species NH3, H2, O2, and N2, th

Analysis of thermal efficiency of a corrugated double-tube heat exchanger with nanofluids

This research investigated convective heat transfer and hydraulic resistance of smooth and corrugated double-tube heat exchangers at various flow rates from 60 L/h to 200 L/h. The inner tube with a thread structure is designed with three pitches, i.e., 4 mm, 6 mm and 8 mm. Nanofluids are used as tube-side fluids to analyze the enhancement of heat transfer on the inner tube side. Results show that

Smartphoned Tourists in the Phygital Tourist Experience

The present thesis explores how the tourist experience is re-articulated through the mediation of smartphones. I adopt the postphenomenological theory of mediation as the overarching ontological position, placing the role of technologies on an ontological level, as mediators of perception and experience. The new tourist that emerges from smartphone mediation is the smartphoned tourist, that is a t

Ozonation of 14C-labeled micropollutants – mineralization of labeled moieties and adsorption of transformation products to activated carbon

Ozonation transformation products (OTPs) are largely unknown compounds that are formed during the ozonation of micropollutants, and it is uncertain to which extent these compounds can be removed by subsequent adsorption to activated carbon. Thus, 14C-labeled micropollutants were ozonated to generate 14C-labeled OTPs, for which the adsorption of the sum of all 14C-labeled OTPs to activated carbon c

Core competencies for a biomedical laboratory scientist - a Delphi study

BACKGROUND: After completing university education, biomedical laboratory scientists work in clinical laboratories, in biomedical research laboratories, in biotech, and in pharmaceutical companies. Laboratory diagnostics have undergone rapid development over the recent years, with the pace showing no signs of abatement. This rapid development challenges the competence of the staff and will most cer

Occupational risk of COVID-19 across pandemic waves: a two-year national follow-up study of hospital admissions

Objective: Assuming that preventive measures to mitigate viral transmission of SARS-CoV-2 at the workplace may have been improved in the course of the COVID-19 pandemic, we examined the occupational risk of COVID-19 related hospital admission across the four pandemic waves in Denmark between week 8, 2020, and week 50, 2021.Methods: The study included 4416 cases of COVID-19 related hospital admissi

Monoclonal Autoantibody Against a Cryptic Epitope on Tissue-Adherent Low-Density Lipoprotein for Molecular Imaging in Atherosclerosis

BACKGROUND: Antibody-based constructs for molecular imaging and therapeutic delivery provide promising opportunities for the diagnosis and treatment of atherosclerosis.OBJECTIVES: The authors aimed to generate and characterize immunoglobulin (Ig)G monoclonal autoantibodies in atherosclerosis for targeting of novel molecular determinants.METHODS: The authors created hybridomas from an unimmunized l

X-instance : en c-uppsats om negativa fakta

Många filosofer verkar gilla tanken om att fakta är verkliga, man menar att fakta är verklighetens byggstenar. Wittgenstein identifierar ?världen? med ?totaliteten av fakta?, och enligt Russell så tillhör fakta den ?objektiva världen?. Jag kommer här inte heller att förneka att fakta är verkliga, så jag antar att fakta tillhör den objektiva världen.

Tradition eller Förnyelse? En fallstudie av det politiska förändringsarbetet i Bromölla kommun

In 2003 the deciding political council in Bromölla municipality requested that an overhaul on the committee and public administration structure should be conducted. In the report Bromölla was characterized as a traditional organization with a low degree of change. This case study will examine why the organization previously has been reluctant to change its structure and why they are willing to do

"democracy in doses"? - en studie kring demokrati och Egypten under Mubarak

Abstract Why don't (some) regimes with formal democratic features undergo transition to democracy? Which are the internal dynamics of these regimes that can offer comprehension to this state of affairs? The main purpose of this thesis is to advance the above questions, and, on a lower level of abstraction, examine the case of Egypt. The Egyptian regime is characterized by, for instance, a mul
