De koop-/aannemingsovereenkomst in breed perspectief
No full textDeze dissertatie gaat over de model koop-/aannemingsovereenkomst met de daarbij behorende algemene voorwaarden. Bij de koop en verkoop van (nog te bouwen) nieuwbouwkoopwoningen in Nederland wordt deze modeloverkomst het meest gebruikt. Overeenkomsten naar dit model werden in het verleden vaak afgesloten met de garantie- en waarborgregeling van het Garantie Instituut Woningbouw (GIW) en daarom ook wel de GIW koop/-aannemingsovereenkomst genoemd. Van de koop-/aannemingsovereenkomst naar dit model bestaat een versie voor eengezinswoningen en een versie voor appartementen. In dit boek is de model koop-/aannemingsovereenkomst met haar algemene voorwaarden onderworpen aan een rechtsvergelijkend onderzoek. De vraag die daarbij centraal heeft gestaan is hoe de regeling van de koop-/aannemingsovereenkomst en de daarbij behorende algemene voorwaarden zich verhoudt tot het Nederlandse en het Europees verbintenissenrecht. Het boek beschrijft vrijwel alle relevante onderwerpen met betrekking tot de rechtsverhouding tussen verkrijger en ondernemer op basis van de model koop-/aannemingsovereenkomst. De volgende onderwerpen komen aan bod: inhoud en aard van de overeenkomst, uitleg van de overeenkomst, het sluiten van de overeenkomst, zekerheidstelling en financiering, betaling, subsidies en kostenwijzigingen, de levering van de grond, wijzigingen, de bouwtijd, de oplevering en de aansprakelijkheid van de ondernemer voor tekortkomingen.RE&HArchitectur
Empowerment door een recht op koop?
No full textDe introductie van de verhuurdersheffing kan leiden tot een toename van het aantal te koop aangeboden huurwoningen door woningcorporaties. Veel corporaties bieden ook al woningen te koop aan, onder meer in zogenaamde Te Woon programma’s. Te Woon biedt de klant van de woningcorporatie naast de mogelijkheid om de woning te huren, ook de mogelijkheid deze te kopen, eventueel met korting (zie bijvoorbeeld Gruis et al., 2005; Noordenne et al. 2009).Real Estate and HousingArchitectur

Do atmospheric aerosols form glasses?
No full textZobrist B, Marcolli C, Pedernera DA, Koop T. Do atmospheric aerosols form glasses? ATMOSPHERIC CHEMISTRY AND PHYSICS. 2008;8(17):5221-5244.A new process is presented by which water soluble organics might influence ice nucleation, ice growth, chemical reactions and water uptake of aerosols in the upper troposphere: the formation of glassy aerosol particles. Glasses are disordered amorphous (non-crystalline) solids that form when a liquid is cooled without crystallization until the viscosity increases exponentially and molecular diffusion practically ceases. The glass transition temperatures, Tg, homogeneous ice nucleation temperatures, Thom, and ice melting temperatures, Tm, of various aqueous inorganic, organic and multi-component solutions are investigated with a differential scanning calorimeter. The investigated solutes are: various polyols, glucose, raffinose, levoglucosan, an aromatic compound, sulfuric acid, ammonium bisulfate and mixtures of dicarboxylic acids (M5), of dicarboxylic acids and ammonium sulfate (M5AS), of two polyols, of glucose and ammonium nitrate, and of raffinose and M5AS. The results indicate that aqueous solutions of the investigated inorganic solutes show Tg values that are too low to be of atmospheric importance. In contrast, aqueous organic and multi-component solutions readily form glasses at low but atmospherically relevant temperatures (≤230 K). To apply the laboratory data to the atmospheric situation, the measured phase transition temperatures were transformed from a concentration to a water activity scale by extrapolating water activities determined between 252 K and 313 K to lower temperatures. The obtained state diagrams reveal that the higher the molar mass of the aqueous organic or multi-component solutes, the higher Tg of their respective solutions at a given water activity. To a lesser extent, Tg also depends on the hydrophilicity of the organic solutes. Therefore, aerosol particles containing larger (≳150 g mol−1) and more hydrophobic organic molecules are more likely to form glasses at intermediate to high relative humidities in the upper troposphere. Our results suggest that the water uptake of aerosols, heterogeneous chemical reactions in aerosol particles, as well as ice nucleation and ice crystal growth can be significantly impeded or even completely inhibited in organic-enriched aerosols at upper tropospheric temperatures with implications for cirrus cloud formation and upper tropospheric relative humidity

A decision theoretic analysis of the unit root hypothesis using mixtures of elliptical models
No full textThis paper develops a formal decision theoretic approach to testing for a unit root in economic time series. The approach is empirically implemented by specifying a loss function based on predictive variances; models are chosen so as to minimize expected loss. In addition, the paper broadens the class of likelihood functions traditionally considered in the Bayesian unit root literature by: i) Allowing for departures from normality via the specification of a likelihood based on general elliptical densities; ii) allowing for structural breaks to occur; iii) allowing for moving average errors; and iv) using mixtures of various submodels to create a very flexible overall likelihood. Empirical results indicate that, while the posterior probability of trend-stationarity is quite high for most of the series considered, the unit root model is often selected in the decision theoretic analysis
A novel model to predict the physical state of atmospheric H2SO4/NH3/H2O aerosol particles
No full textColberg CA, Luo BP, Wernli H, Koop T, Peter T. A novel model to predict the physical state of atmospheric H2SO4/NH3/H2O aerosol particles. ATMOSPHERIC CHEMISTRY AND PHYSICS. 2003;3(4):909-924.The physical state of the tropospheric aerosol is largely unknown despite its importance for cloud formation and for the aerosol's radiative properties. Here we use detailed microphysical laboratory measurements to perform a systematic global modelling study of the physical state of the H2SO4/NH3/H2O aerosol, which constitutes an important class of aerosols in the free troposphere. The Aerosol Physical State Model (APSM) developed here is based on Lagrangian trajectories computed from ECMWF (European Centre for Medium Range Weather Forecasts) analyses, taking full account of the deliquescence/efflorescence hysteresis. As input APSM requires three data sets: (i) deliquescence and efflorescence relative humidities from laboratory measurements, (ii) ammonia-to-sulfate ratios (ASR) calculated by a global circulation model, and (iii) relative humidities determined from the ECMWF analyses. APSM results indicate that globally averaged a significant fraction (17-57%) of the ammoniated sulfate aerosol particles contain solids with the ratio of solid-containing to purely liquid particles increasing with altitude (between 2 and 10 km). In our calculations the most abundant solid is letovicite, (NH4)(3)H(SO4)(2), while there is only little ammonium sulfate, (NH4)(2)SO4. Since ammonium bisulfate, NH4HSO4, does not nucleate homogeneously, it can only form via heterogeneous crystallization. As the ammonia-to-sulfate ratios of the atmospheric H2SO4/NH3/H2O aerosol usually do not correspond to the stoichiometries of known crystalline substances, all solids are expected to occur in mixed-phase aerosol particles. This work highlights the potential importance of letovicite, whose role as cloud condensation nucleus (CCN) and as scatterer of solar radiation remains to be scrutinized
