Magnesium ratio

Figure 4. Dissolved sulfite concentration as a function of magnesium concentration and chloride-to-magnesium ratio for liquors saturated with calcium sulfite and gypsum at pH 5.5 and 50°C...

For a typical limestone scrubber inlet liquor pH range of 5.2-6.0, and for liquors having a chloride-to-magnesium ratio of 0.2 mole/mole or less, the following simplified equation can be used to determine gypsum saturation from calcium measurements ... 

Magnesium concentration = 0-600 m-mole/1 Chloride concentration = 50-500 m-mole/1 Chloride-to-magnesium ratio with magnesia additive = 0.1-1.2 mole/mole Slurry flow rate = 20, 30, or 40 gpm/ft ... 

A large variety of cuprates are known nowadays. They include heteroleptic derivatives R(Y)CuM (Y = alkynyl, halide, amido, alkoxide, thiolato, phosphide M = Li or Mg), and have found widespread application in organic chemistry. Their syntheses and applications are discussed in the other chapters of this book. In addition, compounds in which the copper to lithium (or magnesium) ratio differs from 1 1 are also known examples are R3CuLi2 and the so-called higher order cyanocuprates introduced by Lipshutz et al. [99]. 

Groups I IE metal, it is the unique ratio of magnesium and titanium that defines the catalyst efficacy. In earlier studies Ziegler-Natta catalysts containing varying titanium/magnesium ratios were prepared and then used to polymerize ethylene. 

If these site enrichment factors apply to bulk mineral assemblages, the transition metal/magnesium ratios might be expected to follow the trends...

Magnesium is involved with many neuromuscular activities and cellular pathways that may affect PMS. Low intracellular magnesium levels have been reported in women with PMS compared with controls. It has been suggested that PMS may be related to an increased serum calcium-to-magnesium ratio. Daily or luteal magnesium supplementation of 200-360 mg/day was reported to be minimally helpful in reducing premenstrual fluid retention in women with PMS. A daily supplementation of 200 mg magnesium and 50 mg pyridoxine was found to reduce anxiety-related premenstrual symptoms in women with PMS compared with placebo. ... 

Results were expressed as /liver zinc content was significantly reduced in the alcoholic cirrhotic patients whatever convention was used. For example, the controls had a mean value of 266 /ig Zn/g dry weight whereas the patients with liver disease had a mean of 96 fig Zn/g dry weight and this was statistically significant. 

The quality of brine/salt supplies varies over time, and in particular instantaneous values of the calcium/magnesium ratio can change quickly. 

When calcium/magnesium ratios are high, the structures of precipitates tend to be more favorable. Fortunately, such high ratios are common and are the rule with rock... 

In Britain, type 1 Norway spruce decline has not been seen. A survey of the magnesium contents of foliage indicated that levels were well above the deficiency threshold (Binns et ai. 1986) and there was no indication of an unbalanced nitrogen magnesium ratio (Innes and Boswell...
