Planet Earth is unique in our solar system as an abode of life. In contrast to its planetary neighbours, the presence of liquid water, a benign atmospheric environment, a solid surface and an internal structure providing a protective magnetic field make it a suitable habitat for man. While natural forces have shaped the Earth over millennia, man through his technological prowess may become a threat to this oasis of life in the solar system.

The main aim of the article was to present the investigation results of created megnetorheological fluids using carbonyl iron (CI) particles and analyse their behaviour in terms of the internal structure formation by a control of external magnetic field. Results of the experimental studies of a prototype magnetorheological rotary shock-absorber at various magnitudes of control current was presented in this paper.

AbstractSimultaneously and coherently studying the large-scale magnetic field and the stellar pulsations of a massive star provides strong complementary diagnostics suitable for detailed stellar modelling. This hybrid method is called magneto-asteroseismology and permits the determination of the internal structure and conditions within magnetic massive pulsators, for example the effect of magnetism on non-standard mixing processes. Here, we overview this technique, its requirements, and list the currently known suitable stars to apply the method.

Sample Orientation

AbstractIn vivo imaging of growing and developing samples requires a dynamic adaptation of the sample orientation to continuously achieve optimal performance. Here, we present how, after the injection of magnetic beads, a sample can be freely positioned by applying a magnetic field. We demonstrate its performance for zebrafish on an epi-fluorescence microscope and on a light sheet system for superior multi-view acquisition.

It is becoming recognised that one of the most fruitful sources of information as to the internal structure of atoms is provided by the phenomena attending the passage of swift electrified particles through them. In particular from a consideration of the scattering α-particles it has been found that the atom consists essentially of a very concentrated charge at the centre of the atom surrounded by eletricity of the opposite sign, probably electrons, distributed throughout the remainder of the atom. Further, Darwin and Bohr have attempted to obtain information as to the number and distribution of electrons in the atom by a consideration of the absorption or loss of velocity of the α-particles in passing through matter. The only data for this purpose so far obtainable are provided by the velocity curves, or relations between velocity and thickness of matter traversed, in aluminium as determined by Rutherford, and in mica as determined by Geiger. It seemed, therefore, of interest to make a more complete investigation of the velocity curves in various substances, more particularly as the earlier observations are subject to slight errors due to the assumption that equal thickness of matter have the same air equivalent at different parts of the range of α particles. In the present experiments the velocity curves in gold, copper, aluminium, mica and air have been determined, using as source the α-particles of radium C as in the experiments of Rutherford and of Geiger. The velocities of the α-particles before and after passing through sheets of matter of various thickness were measured by the deflection of the α-particles in a known magnetic field. The apparatus used is shown in fig. 1. It consists essentially of a source of radiation D, a series of absorption foils T, a slit L, to form a pencil of the α-particles, and a zinc sulphide screen M on which the position of the pencil could be observed, the whole being enclosed in an evacuated chamber C between the poles of a large electromagnet.
