German Housing Market

The steep rise in German house prices in recent years raises the question of whether a speculative bubble has already emerged. Using a modified present-value model, we estimate the size of speculative house price bubbles in the German housing market. We do not find evidence for positive bubble accumulation in recent years, and interpret the current bullish run as reflecting the correction of house prices that have been undervalued for more than 10 years. With house prices close to their fair values as of 2018:Q1, our answer to the question is, ‘Not yet, but it is likely soon’.

AbstractWe discuss the evolution of the [O/Fe] as a function of [Fe/H] in the Galaxy. In particular, we discuss the influence of different stellar yields as well as different SN (II, I) rates on the [O/Fe] ratio. Possible explanations for the steep rise of the [O/Fe] ratio at low metallicities, as indicated by recent observations, are critically discussed.

High Reflectance

As an important component in 193nm laser system, high-reflectance (HR) coatings with excellent optical and mechanical properties are needed urgently. In this study, we designed and produced three different HR coatings at 193nm, Al2O3/ AlF3 coating, LaF3/ AlF3 coating and a double stack mirror with combination of Al2O3/ AlF3 and LaF3/ AlF3. With 14 layer pairs, the reflectance of Al2O3/ AlF3 coating could reach 98% which could not get higher duo to the absorption of Al2O3. The reflectance of LaF3/ AlF3 coatings could achieve 98.13% with 15 layer pairs. When the layer pair increased to 16, the reflectance lessened ascribed to steep rise in scattering loss caused by micro-cracks occurred in the coatings. A mirror with combination of Al2O3/ AlF3 and LaF3/ AlF3 could obtain the reflectance of 98.78% as deposited. Even 4 months later the value could still reach 98.47% which was an excellent candidate for practical application.

The total polarization of 1,4-dioxan vapour is reported for 20 temperatures between 118 and 365 �C. The results, considered together with 19 others previously recorded over a range down to 56 �C, indicate the generation of polar forms at higher temperatures, and confirm an earlier suggestion by Gibbs (1961). The variation of P with 1/T �K is shown graphically and may also be qualitatively forecast by equations having a semi-empirical character ; a steep rise of P is predicted as T is increased above about 200 �C.

Harsh Reality

Due to the recent coronavirus pandemic, there is a steep rise in the use of alcohol-based hand sanitizers (ABHSs) over the past few months. For them to be effective against microorganisms, the minimum recommended concentration of alcohol is 60%. This high alcohol content makes the sanitizers easily flammable. Although, they are extremely convenient to use, they can also prove to be a hazard if used in an improper manner. Guidelines have been published for safe manufacturing and distribution of these sanitizers. There are recommendations for storage and use, which should be adhered to in a strict manner. Their use by children should always be supervised. We report four cases of burn injuries caused by injudicious use of alcohol-based sanitizers. The flammable nature of ABHSs can also be exploited as witnessed in one of our cases. With this report, we wish to emphasize that judicious and correct use of these seemingly benign products is essential.
