Smart City : Leitfaden zur Umsetzung von Smart-City-Initiativen in der Schweiz

Dieser Leitfaden zur Umsetzung von Smart-City-Initiativen in der Schweiz wurde im Rahmen des Programmes EnergieSchweiz für Gemeinden konzipiert. Das Bundesamt für Energie (BFE) fördert damit die Umsetzung der nationalen Energiepolitik in den Bereichen Energieeffizienz und erneuerbare Energie. Mit dem Programm EnergieSchweiz für Gemeinden unterstützt das BFE gezielt Projekte auf kommunaler Ebene

Saltation under Martian Gravity and its Influence on the Global Dust Distribution

Dust and sand motion are a common sight on Mars. Understanding the interaction of atmosphere and Martian soil is fundamental to describe the planet's weather, climate and surface morphology. We set up a wind tunnel to study the lift of a mixture between very fine sand and dust in a Mars simulant soil. The experiments were carried out under Martian gravity in a parabolic flight. The reduced gravity was provided by a centrifuge under external microgravity. The onset of saltation was measured for a fluid threshold shear velocity of 0.82$\pm$0.04 m/s. This is considerably lower than found under Earth gravity. In addition to a reduction in weight, this low threshold can be attributed to gravity dependent cohesive forces within the sand bed, which drop by 2/3 under Martian gravity. The new threshold for saltation leads to a simulation of the annual dust cycle with a Mars GCM that is in agreement with observations

Supporting the Transformation Process to Smart Sustainable Cities in Switzerland: Implementation Guidelines and Promising Practices

Challenges such as the digitalisation of administration, the change of cities through urbanisation, climate change and the restructuring of infrastructure systems in the energy and mobility sector require a rethinking of the existing urban development approaches. The Smart City concept enables cities to tackle these challenges in the sense of a holistic development approach across departments, networked with partners and supported by digital technologies. In Switzerland's view, the Smart City concept goes far beyond internal administrative e-government and digitisation strategies. The overriding goal is to develop efficient and resource-saving solutions while at the same time increasing the quality of life and the attractiveness of the location. The overall aim is to create an innovative urban environment that involves the inhabitants and the economy and opens up new design possibilities

Leitfaden Smarte Quartiere : Ideenentwicklung und Prozessgestaltung für Genossenschaften und andere Akteure der Quartierentwicklung

Ein smartes Quartier vernetzt auf intelligente Weise die Bewohner und Bewohnerinnen, sowie Gewerbe, Logistik und Warenströme, um auf nachhaltige Weise eine hohe Lebensqualität zu schaffen.Die soziale Vernetzung unter den Quartierbewohnerinnen und Quartierbewohnern ermöglicht eine Sharing-Kultur und ist eine Bereicherung im alltäglichen Leben. Der Verkehr ist intelligent und die Warenströme sind effizient organisiert, Energie und natürliche Ressourcen werden dabei nachhaltig produziert und verantwortungsvoll genutzt. Informations- und  Kommunikationstechnologien werden dort eingesetzt, wo sie zur Lebensqualität und einer effizienten Organisation beitragen. Um dieser Idee näher zu kommen, braucht es einen koordinierten Prozess und gute Ideen für smarte Quartierprojekte. Dieser Leitfaden richtet sich an Genossenschaften und andere Akteure der Quartierentwicklung und soll Ideen für smarte Massnahmen im Quartier, sowie Anstösse für die Prozessgestaltung und Umsetzung bereitstellen

Applications of fluorescent sensor based on 1H-pyrazolo[3,4-b]quinoline in analytical chemistry

Fluorescent dye 2-[(2-Hydroxyethyl)-(1,3-diphenyl-1H-pyrazolo[3,4-b]quinolin-6-ylmethyl)-amino]ethanol (LL1) was examined for its efficiency in the detection of small inorganic cations (lithium, sodium, barium, calcium, magnesium, cadmium, lead and zinc). The dye was synthesized in the laboratory and investigated by means of both, steady-state and time-resolved fluorescence techniques. This compound acts as a fluorescent sensor suitable for detection of small inorganic cations (lithium, sodium, barium, calcium, magnesium, cadmium, lead and zinc) in strongly polar solvent (acetonitrile). An electron transfer from the electro-donative part (receptor) of the molecule to the acceptor part (fluorophore) is thought to be the main mechanism that underlies functionality of the compound as a sensor. This process can be retarded upon complexation of the receptor moiety by inorganic cations. Relatively high sensitivity but poor selectivity of the aminoalcohol thatcontains indicator towards the two-valued cations was observed. However, upon addition of some amounts of water the selectivity of this sensor has been enhanced (especially towards lead cation). The preliminary results in analytical application of the sensor are discussed
