Meat bone meal as nitrogen and phosphorus fertilizer

Meat bone meal (MBM) contains considerable amount of nutrients (~8 % N, ~ 5 % P and ~ 10 Ca). To quantify and qualify MBM use as an N and P fertilizers, two field experiments were done on spring barley and oat in 2000 and 2001

Bursts of ULF noise excited by sudden changes of solar wind dynamic pressure

International audienceWe present the results of analysis of the dayside magnetic pulsation response to a sudden change in solar wind dynamic pressure. We concentrate on the events when a burst or a series of short-lived bursts in the Pc1 frequency range with the repetition period of 7?15 min were observed on the ground around the local noon. Not every impulse of large amplitude caused this phenomenon. We have found that the ULF bursts were excited when the spectrograms of the DMSP satellites showed a signature of 10?30 keV ions in the vicinity of the magnetic flux tube of the ground observatory, that may be related to a geomagnetic storm preceding the event. In light of this finding a possible model of the phenomenon is suggested in which the hot protons influence significantly both the generation and modulation of Pc1 activity

A Small Interstellar Probe to the Heliospheric Boundary and Interstellar Space

The Small Interstellar Probe m1ss1on would be designed to cross the solar wind termination shock and the heliopause, and make a significant penetration into nearby interstellar space. The principal scientific objectives of this mission would be to explore the structure of the heliosphere, to investigate its interaction with the interstellar medium, and to explore the nature of the interstellar medium itself. These studies would be carried out by a ~200 kg spacecraft carrying a scientific payload designed to make comprehensive, in situ measurements of both heliospheric and interstellar plasma, fields, energetic particles, gas, and dust. New trajectory calculations indicate significantly improved performance over earlier studies with larger spacecraft, including spacecraft velocities ranging from -6 to -14 AU/yr., depending on trajectory and launch vehicle

Policy instruments and welfare state reform

A core, but so far untested, proposition of the new politics perspective, originally introduced by Paul Pierson, is that welfare state cutbacks will be implemented using so-called ‘invisible’ policy instruments, for example, a change in indexation rules. Expansion should, by implication, mainly happen using ‘visible’ policy instruments, for example, a change in nominal benefits. We have coded 1030 legislative reforms of old-age pensions and unemployment protection in Britain, Denmark, Finland and Germany from 1974 to 2014. With this unique data at hand, we find substantial support for this crucial new politics proposition
