Major Inorganic Ions in Bottled Waters from Several Polish and Romanian Mineral Waters
Bulletin of University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca: Food Science and Technology, 2019 Mineral waters are important sources of micro- and macroelements for humans, thus its composition ought to be supported with good knowledge on their chemical composition and be controlled systematically. The aim of the study was to analyze the content of

Lack of direct evidence for a functional role of voltage-operated calcium channels in juxtaglomerular cells [PDF]
, 1990 In this study we have examined the role of voltage-gated calcium channels in the regulation of calcium in juxtaglomerular cells. Using a combination of patch-clamp and single-cell calcium measurement we obtained evidence neither for voltage-operated ...

Field efficacy of new compounds to replace copper for scab control in organic apple production [PDF]
, 2007 Efficacy of compounds was investigated in field experiments in Denmark and the Netherlands according to EPPO guidelines. Some Yucca extracts and potassium bicarbonate had an efficacy similar to sulphur on leaves.

Recombination, ionization, and nonequilibrium electrical conductivity in seeded plasmas [PDF]
, 1966 New data are presented which provide direct experimental confirmation of the validity of a physical model which has been widely employed to predict the electrical conductivity of dense, two-temperature, seeded plasmas.

Co-Mn-Al mixed oxides promoted by K for direct NO decomposition: Effect of preparation parameters [PDF]
, 2019 Fundamental research on direct NO decomposition is still needed for the design of a sufficiently active, stable and selective catalyst. Co-based mixed oxides promoted by alkali metals are promising catalysts for direct NO decomposition, but which ...

The conduction pore of a cardiac potassium channel. [PDF]
, 1998 Ion channels form transmembrane water-filled pores that allow ions to cross membranes in a rapid and selective fashion. The amino acid residues that line these pores have been sought to reveal the mechanisms of ion conduction and selectivity. The pore (P)

Potassium silicate-zinc oxide solution for metal finishes [PDF]
, 1970 Examples of zinc dust formulations, which are not subject to cracking or crazing, are fire retardant, and have high adhesive qualities, are listed. The potassium silicate in these formulations has mol ratios of dissolved silica potassium oxide in the ...

Effects of Potassium Source and Secondary Nutrients on Potato Yield and Quality in Southcentral Alaska. [PDF]
, 1990 Calcium (Ca), magnesium (Mg), and sulfur (S) are required for the growth and development of all higher plants. They are commonly referred to as secondary nutrients because they are less often limiting to plant growth than the primary nutrients nitrogen ...
