Sodium caused

Treatment. Treatment of poisoning from soluble barium salts may be preventive or curative (47,51). Preventive treatment involves inhibition of intestinal absorption by administering such soluble sulfates as magnesium or sodium, causing precipitation of barium sulfate in the alimentary tract. 

Sodium, potassium and sodium-potassium alloys Liquid sodium, potassium or alloys of these elements have little effect on niobium at temperatures up to 1 000°but oxygen contamination of sodium causes an increase in corrosionSodium does not alloy with niobium . In mass transfer tests, niobium exposed to sodium at 600°C exhibited a corrosion rate of approximately 1 mgcm d . However, in hot trapped sodium at 550°C no change of any kind was observed after 1 070 h . 

Soils properties are very sensitive to the type of exchangeable ions. Calcium imparts favorable physical properties to the soil, while adsorbed sodium causes clay dispersion and swelling. It is generally recognized that an exchangeable sodium percentage of 10 is sufficient to cause soil dispersion, reduction of soil permeability and impaired growth of some crop plants. On the other hand, excess salt concentration prevents the dispersive effect of adsorbed sodium. 

It also reacts violently with lithium in the molten state as well as with sodium, causing emissions of flaming metal. The reaction takes place with pure sodium as well as with sodium combined with calcium or sodium oxide. 

If samples were taken for the GPC and GC it was found that after all the dichloride was consumed that the product was distributed into the three peaks on the GPC PI, PII, PHI (Figure 1). Although high molecular weight material was present as soon as the dlchloride was consumed, continued reflux with sodium caused changes in the molecular weight, particularly of PII (Table I). This was very... 

Passage of moist hydrogen sulfide over unheated sodium causes melting and then usually ignition of the metal. Mixtures of sodium (or its alloy with potassium) and carbon disulfide are shock-sensitive explosives. 

The enteric-coated tablet divalproex sodium causes fewer GI side effects. It is metabolized in the gut to valproic acid. When switching from Depakote to Depakote-ER, the dose should be increased by 14% to 20%. Depakote ER may be given once daily. 

The flask is heated on a water bath until the alcohol boils. The pieces of sodium are then (one at a time) introduced through the vertical limb. The benzene adhering need not be removed from the sodium. The first pieces of sodium cause a vigorous reaction, but the alcohol is kept at a boil. When the reaction becomes sluggish a further 100 ccs of absolute alcohol is added and... 

Sulphur and phosphorus do not affect the fluoride even at 500° C., but hot sodium causes gradual decomposition, with complete absorption. 

Placing the chloride in contact with finely divided sodium caused an explosion after a short induction period [1]. Reaction with sodium sulfide gives molybdenum disulfide in a vigorous deflagration autoignition will occur on mixing if the sodium sulfide is... 

The most potent type of diuretic, loop diuretics are named after the loop of Henle, a component of a nephron. The nephrons are the filtering units of the kidney, and are responsible for moving fluids and waste out of the bloodstream, resulting in urine formation. The loop of Henle is a branch within each nephron where sodium and potassium are reabsorbed back into the bloodstream instead of being filtered into the urine. Loop diuretics inhibit this action and promote excretion of the sodium and potassium instead, along with calcium and magnesium. Since excess sodium causes excess fluid build-up, this results in fluid loss. Furosemide (Lasix), bumetanide (Bumex), torsemide (Demadex), and ethacryinic acid (Edecrin) are all loop diuretics. 

Dietary restriction of sodium causes lithium retention and an increased risk of toxicity. The same would be true of a diet that markedly restricted fluid intake. In brief, dietary extremes should be avoided. 

Zettner and Seligson (Z3) conducted an extensive study of calcium interferences deriving from serum constituents and other substances. In the air-acetylene flame, no effect was seen from excess concentrations of the ions of potassium, ammonium, magnesium, chloride, bicarbonate, and hydroxide. Phosphate, sulfate, oxalate, and EDTA acted as strong anionic depressors. Sodium caused a small but distinct depression of... 

The patient experiences hyperosmolality—a higher than normal concentration of sodium—causing water to shift out of cells and into extracellular space, resulting in cellular dehydration. 

This process, going hand in hand with the fall in the price of metallic sodium, caused an enormous reduction in the price of cyanide from 160 per ton in 1895 to only yo per ton in 1909. No doubt, in consequence of the production of cheap synthetic ammonia (see page 53), a further fall in price of cyanide may be anticipated. 

It is ivdl known that Wohler obtained alnminum in the for n of a powder when he treated the chloride with potassium if one modifies Wohlers pro cedure in an appropriate way the decomposition of chloride of aluminum can be regulated in such a way that there results a white-heat sufficient to cause the metal particles to fuse into spheres. Heating to a lively red-heat in a porcelain crucible the resulting mass, which consists of the metal and chloride of sodium, causes excess chloride of aluminum to escape, leaving behind a salt mass that produces an acidic reaction, and in which can he found more or less large spheres of entirely pure aluminum ...

Cholera and pertussis toxins catalyze the covalent addition of ADP-ribose to specific sites in the ot subunits of Gs and Gi, respectively. This modification inhibits GTPase action in the ot subunits and converts them to irreversible activators of adenylate cyclase. As a result, cAMP accumulates. In the intestine, the response to this is an uncontrollable secretion of water and sodium—causing severe diarrhea and dehydration. 

Thus, as follows from the analysis of the exchange kinetic characteristics, the substitution of copper for sodium causes a considerable change in the exchange mechanism. 

Stoichiometric silicon nitride (Si3N4) often is used for chemical passivation and encapsulation of silicon bipolar and MOS devices, because it serves as an extremely good barrier to diffusion of water and sodium ions. Water causes device metallization to corrode and sodium causes devices to become electrically unstable. Silicon nitride is also used as a mask for the selective oxidation of silicon, and as a strong dielectric in MNOS (metal-nitride-oxide-silicon) structures. 

Treatment of [Tc (NAr) iir (Ar=2.6-diisopropylphenyl) (Sect. 12.14) [35] with two equivalents of sodium causes the green solution to rapidly change to the orange-brown color of [Tc (NAr)j " ... 

The first step in the strength loss process is the hydration of sodium. Little strength is lost in this step since the polysilicic acid network is not destroyed. Absorption of another water molecule by sodium causes strength failures through cleavage of the silicate network, probably catalized by hydroxide ion. When even small numbers of silicate bonds are broken, the polysilicate network is destroyed and the strength of the bound sand system is lost.

Heating of circuit with frozen sodium should start from sodium free level, and each heater section should be switched on in the strict sequence only after sodium in the previous section has been molten. If this sequence of procedures is not observed, expansion of sodium caused by phase transition occurs in the restricted volume. This is the cause of sodium communication mptures. This was caused by either incorrect arrangement of heaters, or errors in operating instructions, or errors of personnel. 

Owing to neptunium introduction, the SVRE value caused by the removal of 15 kg of sodium from the central area of the insert becomes less negative by about 0.3 Pef, while the removal of 0.15 kg of sodium causes its change from - 0.16%Pef to +...
