Nonmonotonic (in concentration) conductivity of aqueous solutions of fungal melanin
Semiconductor Physics, Quantum Electronics & Optoelectronics, 2018 The conductivity of aqueous (distilled and natural water) solutions of fungal melanin (purified and non-purified) has been studied. It has been shown that, in the presence of impurities, the conductivity of solution increases (for the concentration 0.1 ...

Processing and characterization of CaTiO3 perovskite ceramics [PDF]
Processing and Application of Ceramics, 2014 Calcium titanate (CaTiO3) ceramics with perovskite structure were produced by solid state reaction. Calcium carbonate (CaCO3) and titanium dioxide (TiO2) were mixed (in molar ratios 1/1 and 3/2), and the obtained mixtures were calcined at 1150 °C in ...

Geomagnetic Impulses and the Electrical Conductivity of the Lower Mantle [PDF]
, 1991 This thesis is an investigation of the changes in the magnetic field as measured at the surface of the Earth on the time-scale of months to decades. In particular the phenomena of geomagnetic "impulses" or "jerks" are investigated.

Dielectric properties of deformed early potatoes
Research in Agricultural Engineering, 2008 The permittivity of potato tissue was studied during uniaxial compression of cylindrical specimens prepared from two early varieties. Both the real and the imaginary permitivity components were determined repeatedly during the loading and unloading tests.

Integration of sensors for dam water quality analysis – a prototype
Water Science and Technology, 2021 Water consumed is stored in several water bodies in and around us, out of which dams accommodate a major portion of water. The quantity and quality monitoring of water in dams is troublesome due to their large surface area and high depths.

Pediatric Blood &Cancer, EarlyView.ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...
