This article aims to contribute to discussions and reflections upon the practice and theory of fire safety design. Are we reaching the results we want by the best available means? The theoretical framework of fire safety design is today restricted by a linear design process where mainly quantitative data and methods matters. A deterministic approach to safety ignores the decision-making context an
Bacterial ice-nucleating particles (INP) have the ability to facilitate ice nucleation from super-cooled cloud droplets at temperatures just below the melting point. Bacterial INP have been detected in cloud water, precipitation, and dry air, hence they may have an impact on weather and climate. In modeling studies, the potential impact of bacteria on ice nucleation and precipitation formation on
Bacterial ice-nucleating particles (INP) are present in the atmosphere and efficient in heterogeneous ice-nucleation at temperatures up to -2 °C in mixed-phase clouds. However, due to their low emission rates, their climatic impact was considered insignificant in previous modeling studies. In view of uncertainties about the actual atmospheric emission rates and concentrations of bacterial INP, it
Some bacteria have the unique capacity of synthesising ice-nucleation-active (INA) proteins and exposing them at their outer membrane surface. As INA bacteria enter the atmosphere, they may impact the formation of clouds and precipitation. We studied members of airborne bacterial communities for their capacity to catalyse ice formation and we report on the excretion of INA proteins by airborne Pse
On the 20th anniversary of the euro, this column traces public support for the single currency and public trust in the ECB. The crisis years slightly dented support for the euro while trust in the ECB fell sharply. The recovery increased support for the euro, but while trust in the ECB has also risen, it remains below its pre-crisis levels. Unemployment is the key factor driving public support for
The euro as a common currency has recently been the subject of harsh criticism by economists from both sides of the Atlantic, including claims that citizens in some Eurozone countries are turning against it. This column argues that, in fact, the euro currently enjoys comfortable popular support in each of the 12 original member states of the Eurozone and that potential upcoming referenda in any of
The Eurozone crisis has meant slow growth, rising unemployment, and social unrest. This column gauges the impact of all this on European citizens‘ opinions about the euro and EU institutions. Using Eurobarometer surveys, the authors find that, within the Eurozone, the crisis has only marginally lowered support for the euro but has led to a sharp fall in public trust in the ECB.
Commençons par situer les travaux de Maurice Halbwachs en amont et en aval. En amont, on peut y voir une anticipation, à la fois de ce qui est devenu depuis un classique de la littérature sur l’architecture, « L’image de la cité » de Kevin Lynch, publié en 1960, et aussi, dans une direction assez différente, de la notion de cognition étendue, telle qu’elle est abordée en ce moment, dans la science
Parkinson’s Disease (PD) is the most prevalent neurodegenerative movement disorder. Despite investigative efforts into the pathogenesis of the disease, the aetiology and mechanism of PD remains unknown, with multiple factors and cellular pathways known to play a part. But the genetic component of the disease, as well as enhanced vulnerability of the midbrain dopaminergic neurons of the Substantia
Many items of culture which are conveyed from one culture to another may take verbal form, and then constitute what Jakobson called "translation proper." If such diffusions involve a co-occurrent change of semiotic systems, they are of such a different nature, that we better reserve another term for it: transposition. Whether or not accompanied by transpositions, such as pictures, translational ev
Cerebral autoregulation is crucial for maintaining cerebral blood flow and perfusion. In recent years, the importance of cerebral oxygenation in syncope and orthostatic intolerance (OI) has received increased attention. Cerebral tissue oxygenation can be measured by using near-infrared spectroscopy (NIRS), which determines the ratio of oxygenated hemoglobin to total hemoglobin in cerebral tissue.
The importance of effective facility management in enabling organizations to function efficiently is widely recognized. Total Facility Management offers a comprehensive treatment of what facility management means to owners, operators, tenants, facility managers and professional advisors, as well as containing advice on how facilities can be better managed from a number of perspectives. It consolid
The alarming rates of extinction and degrading ecosystems call for new means of understanding and accounting for how people depend on nature. Ecosystem services (ES) is a contested but widely applied concept aiming to connect ecosystem functions to human wellbeing and to assess and account for how nature matters in decision-making. More diverse frameworks and ideas of value intended for assessment
Bastin et al (Reports, 5 July 2019, p. 76) claim that 205 gigatonnes of carbon can be globally sequestered by restoring 0.9 billion hectares of forest and woodland canopy cover. Reinterpreting the data from Bastin et al, we show that the global land area actually required to sequester human-emitted CO2 is at least a factor of 3 higher, representing an unrealistically large area.
Background: In 2001, the EU nickel directive was introduced to prevent contact allergy to nickel. Contact allergy to palladium and/or cobalt is often seen together with contact allergy to nickel. Objectives: To compare the contact allergy prevalence of nickel, palladium, and cobalt allergy before and after the introduction of the EU nickel directive in consecutive patients with dermatitis. Methods
Biomass is an essential sustainable and carbon-neutral energy source. Through thermochemical conversion processes, such as combustion and gasification, biomass can generally be used in boilers to provide heat and/or power. Biomass fuels contain varying amounts of potassium, chlorine and sulfur. The release of these elements, especially in the form of potassium chloride (KCl), in the thermal conver
