Summary Here, we describe a method for loading a calcium-sensitive dye through the frog nerve stump into the nerve endings. We also present a protocol for the recording and analysis of fast calcium transients in the peripheral nerve endings. Cite this Article Copy
77.95%. These calcium concentra-tions are attributed to the formation lithology of the studied area. 2. Heavy metal contents in soil Levels of heavy metals in soil are shown in table 2. The mean concen - trations were 0.99 (mg / kg) for Cd, 14.93 (mg / kg) for Cu
In the trials carried out in a greenhouse in Morocco, the crop yield increased by 20% with 50% less water consumption. The main raw material of Porous Alpha is used glass bottles and solar panel glass. They are crushed into a powder, then calcium carbonate

Calcium is an alkaline-earth metal that is an important component of the cell walls of aquatic plants, and of the bones and shells of aquatic animals. Calcium ions find their way into water as it flows over rocks that contain calcium, such as limestone and gypsum.
The present overview is intended to point the readers’ attention to the important subject of calcium orthophosphates. These materials are of the special significance because they represent the inorganic part of major normal (bones, teeth and dear antlers) and pathological (i.e. those appearing due to various diseases) calcified tissues of mammals. Due to a great chemical similarity with the
Thus, 2g of sulfate calcium was immersed in 200 ml of metal ions of varying time ranging from 0 to 180 min in 250ml Erlenmeyer flasks at room temperature (298K) and the pH 6.01 for the case of nickel and pH 5.70 for the case of lanthanum.

During the development of calcium carbonate limestone, other elements are present and some of them get into the calcium carbonate structure. One of these is the metal element magnesium. It so happens that magnesium atoms are similar enough in size to calcium, only slightly smaller, and its electron valence matches that of calcium.

Rhassoul (or Ghassoul) Clay, not to be confused with Moroccan Red Clay, is rich in potassium, magnesium, calcium and sodium. Mined in Eastern Morocco, Rhassoul Clay is found to have higher percentages of magnesium and silica, making it silky smooth and …
for calcium sulfate and 400–600 mg/litre (median 525 mg/litre) for magnesium sulfate (NAS, 1977). In a survey of 10–20 people, the median concentrations that could be detected by taste were 237, 370 and 419 mg/litre for the sodium, calcium and
BONDERITE® M-ZN 20 (GRANODINE 20) is a nitrate, nitrite-accelerated phosphating metal pre-treatment which produces micro-crystalline zinc calcium phosphate layers on steel and iron surfaces. This provides very good corrosion protection and excellent adhesion for painting or coating.
Summary We present a technique for contactless micromanipulation of vesicles, using localized calcium ion gradients. Microinjection of a calcium ion solution, in the vicinity of a giant lipid vesicle, is utilized to remodel the lipid merane, resulting in the production
Calcium phosphate refers to numerous materials consisting of calcium ions (Ca 2+) together with orthophosphates (PO 4 3−), metaphosphates or pyrophosphates (P 2 O 7 4−) and occasionally oxide and hydroxide ions. Especially, the common mineral apatite has formula Ca 5 (PO 4) 3 X, where X is F, Cl, OH, or a mixture; it is hydroxyapatite if the extra ion is mainly hydroxide.
