A model of financialization of commodities
We analyze how institutional investors entering commodity futures markets, referred to as the financialization of commodities, affect commodity prices. Institutional investors care about their performance relative to a commodity index. We find that all commodity futures prices, volatilities, and correlations go up with financialization, but more so for index futures than for nonindex futures. The equity-commodity correlations also increase. We demonstrate how financial markets transmit shocks not only to futures prices but also to commodity spot prices and inventories. Spot prices go up with financialization, and shocks to any index commodity spill over to all storable commodity prices
Spectral variations of AeBe Herbig stars in the Mon R1 association
We present the change in the Halpha emission-line profile of the spectra of
some AeBe Herbig stars. In the spectrum of VY Mon, Halpha may have one of three
profile types: P Cyg, P Cyg III or single line in accordance with the
brightness variations of the star. HD259431 now shows a double Halpha profile
with the red component stronger than the blue component, while in the earlier
observations the blue peak was higher than the red peak. Finally, the last
Halpha profile of LkHalpha215 is very similar to that obtained by Finkenzeller

Using temporary water to resupply fresh water (on example Kanaka SCC)
In boarding houses, located at the mouth of the Kanaka beam (SCC), the problem
of provision with fresh drinking water worsened. So far, the provision with drinking
water was carried out with water wells from the aquifer at a depth of up to 15 m from
the earth surface
