The XIVth IAGA Workshop on Geomagnetic Observatory Instruments, Data Acquisition, and Processing was the first of its kind to take place in China, the country regarded as the birthplace of geomagnetism. These workshops are scheduled to take place every 2 years, and as such, it is an important meeting for all magnetic observatories to attend. These workshops serve to provide the standard of obse...

We present an overview of recent superconducting quantum interference device (SQUID) research and development in Europe. History, theory and fundamental experiments and especially practical SQUIDs and SQUID readout were covered by Part I of this overview. Today, the SQUID itself is a rather mature device, the most sensitive magnetic flux and field detector, which finds use also as an amplifier....

Magnetotactic bacteria are a miscellaneous cluster of microorganisms having geomagnetism aided navigation property against applied magnetic field. This oneness is because of the presence of intracellular organelles magnetosomes comprising a membrane-bound crystals of magnetic iron minerals which are formed due to partial reduction of ferric iron in the iron rich environment. It can biomineraliz...

Some Bravais lattices have a particular geometry that can slow down the motion of Bloch electrons by pre-localization due to the band-structure properties. Another known source of electronic localization in solids is the Coulomb repulsion in partially filled d or f orbitals, which leads to the formation of local magnetic moments. The combination of these two effects is usually considered of lit...

The behaviors of dairy cows, such as feeding, ruminating, running, resting (standing, lying), head-shaking, drinking, and walking, can indicate their health status. In this study, a multi-sensor was used to collect data cow's multi-behaviors for research on behavior recognition. Firstly, collar style acquisition system equipped with geomagnetic acceleration sensors the behavioral cows during da...

Research over the past 10 years into the pineal gland and its possible connection with a psiconducive state of consciousness (Roney Dougal, 1986 & 1989), has recently become linked with research on the connection between the earth's magnetic field (EMF) and psi awareness (Persinger, 1988a; Roney Dougal, 1988). This connection is explored with particular reference to neurochemical research into ...

Abstract This study calculates and comparatively tests the dynamic equilibrium angle characteristics of spin-stabilized projectile. Based on analysis spatial relationships angular motion projectile, a six-degrees-of-freedom (6 DoF) model is constructed. Through simulation calculation, changing law main parameters affecting with time obtained, then whole-trajectory curve drawn using approximate ...

As New Zealander geophysicist Gillian Turner’s book North Pole, South Pole: The Epic Quest to Solve the Great Mystery of Earth’s Magnetism [1] shows, our planet’s magnetic properties have intrigued people since a...
