Ragnar Metals Ltd (ASX:RAG) has discovered multiple conductors associated with polymetallic mineralisation at its Viken ...

Quasiperiodic (QP) very low frequency (VLF) emissions are intriguing phenomena observed in the Earth's magnetosphere, characterized by their periodic intensity modulation. These emissions are ...

Abstract: In this letter, an analytical method for studying the theory of an arbitrarily oriented multi-feed very-low-frequency (VLF: 3-30 kHz) linear antenna in a cold magnetoplasma is proposed. The ...

Results: Multivariable linear regression models in the baseline analysis revealed independent relationships between tonsil size and obstructive apnea-hypopnea index (OAHI), adenoidal-nasopharyngeal ...

The energy in the Very Low Frequency (VLF) band was then obtained through trapezoidal integration of the Power Spectral Density (PSD) function. Qualitative variables were described using absolute and ...

Initial drilling at Hampore, which has commenced, is designed to test beneath a recently identified high-grade existing outcrop identified through mapping and rock chip sampling, which returned ...

CFEWs exhibit horizontal line characteristics higher than the background on spectrograms. In this study, we focus on Very Low Frequency (VLF) waveform data and power spectral data collected by the ...

There are three major kinds of technology that you should be familiar with to choose your detector, which are very low frequency (VLF), pulse induction (PI), and multiple frequency (MF). Simply put, ...

The frequency dependencies of the magnetic field generated by ... An analysis of the nonlinear transformation of the spectrum: VLF (very low frequencies ~ 1 - 10 kHz) at a depth of about 30 km , ELF ...

Material erosion rates due to PD activity are very ... hipot test. VLF has the advantage that the energy requirements are 1/600 for 60 Hz voltages and 1/500 for 50 Hz voltages, so the test sets can be ...

The machine, in general, is very sturdy and well-built with intuition digital numeric ... The package includes four AA batteries so you can use it right out of the box. Despite the low price point, it ...
