The principle of proportionality revisited: interpretations and applications. : interpretations and applications

The principle of proportionality is used in many different contexts. Some of these uses and contexts are first briefly indicated. This paper focusses on the use of this principle as a moral principle. I argue that under certain conditions the principle of proportionality is helpful as a guide in decision-making. But it needs to be clarified and to be used with some flexibility as a context-depende

A true single-phase-clock dynamic CMOS circuit technique

The authors describe two dynamic circuit techniques, using only a single-phase clock which is never inverted. This class of circuits has the advantages of simple clock distribution, small area for clock lines reduced clock skew problems, and high speed. Several examples are demonstrated.

The Affects of Virtual Space on Learning: A Literature Review

This paper examines how the effects of virtual space on learning have been elucidated in recent research with the aim of providing both a comprehensive picture of the current state of research and interesting avenues for future projects. Drawing on a multidisciplinary review, it identifies five key themes that together constitute research in virtual space and learning: analogies between the study

Effect of upstream clopidogrel treatment in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Aims Immediate treatment with a loading dose of clopidogrel at diagnosis of ST-segment elevation myocardial infarction (STEMI) is recommended by ESC/AHA/ACC guidelines in patients eligible for primary percutaneous coronary intervention (PCI). However, the evidence for this practice is scarce. Methods and results All patients who underwent PCI for STEMI in Sweden between 2003 and 2008 were identifi

Distinct and overlapping patterns of cytokine regulation of thymic and bone marrow-derived NK cell development.

Although bone marrow (BM) represents the main site for postnatal NK cell development, recently a distinct thymic-dependent NK cell pathway was identified. These studies were designed to investigate the role of cytokines in regulation of thymic NK cells and to compare with established regulatory pathways of BM-dependent NK cell compartment. The common cytokine receptor gamma-chain (Il2rg) essential

From the ivory tower to the market place: Knowledge organisations in the development of biotechnology clusters

In the emerging knowledge economy, universities are adopting a key role as producers of scientific knowledge and skills, and they are experiencing far reaching changes in their tasks. Their main mission is no longer confined to education and research, but increasingly also covers technology transfer and commercialisation activities. The aim of this paper is to examine to what extent this phenomeno

von Langenbeck procedures at 8 months or Wardill at 18 months for primary repair of cleft palate in adult Swedish patients with unilateral complete cleft lip and palate: A study of facial growth.

The purpose of this study was to compare facial growth in patients with unilateral complete cleft lip and palate (UCLP) in whom the palate was repaired with the von Langenbeck procedure at 8 months (L-8), or the Wardill procedure at 18 months (W-18). A total of 151 unaffected subjects were used as a reference series. Sixty-one adult patients, 34 in the L-8 group and 27 in the W-18 group, were inve

A multi-centre study on quality of life and absenteeism in patients with CRS referred for endoscopic surgery

Aims: This study summarises the health-related quality of life (HRQOL) scores and absenteeism caused by sinus problems in patients awaiting surgery with the diagnoses recurrent acute rhinosinusitis (RARS), chronic rhinosinusitis with nasal polyps (CRS+NP) or CRS without nasal polyps (CRS-NP), in a prospective multi-centre study. Methodology: Two hundred and seven patients with RARS, CRS+NP or CRS-

Polynomial Solvers for Geometric Problems - Applications in Computer Vision and Sensor Networks

Given images of a scene taken by a moving camera or recordings of a moving smart phone playing a song by a microphone array, how hard is it to reconstruct the scene structure or the moving trajectory of the phone? In this thesis, we study and solve several fundamental geometric problems in order to provide solutions to these problems. The key underlying technique for solving such geometric probl

Study I: Effects of 0.06% and 0.10% blood alcohol concentration on human postural control.

Alcohol intoxication causes many accidental falls presented at emergency departments, with the injury severity often related to level of blood alcohol concentration (BAC). One way to evaluate the decline in postural control and the fall risk is to assess standing stability when challenged. The study objective was to comprehensively investigate alcohol-related impairments on postural control and ad

Med Newton bland gungor och karuseller

I nöjesparkens åkattraktioner är det din egen kropp som upplever krafterna i Newtons lagar, när den accelereras i 1, 2 och 3 dimensioner. Du får uppleva det fria fallets tyngdlöshet - eller känna dig mycket tyngre än vanligt när berg- och dalbanan går igenom en dal. Åkattraktinerna ger mpnga fina exempel på krafter i idealiserade situationer, som till exempel Slänggungan/Kättingflygaren på Liseber
