Mass gain

It does not have the same value, however, because eqn. (21.5) refers to thickness gain and not mass gain the two can be easily related if quantities like the density of the oxide are known. 

It must be kept in mind that the reaction term will not occur in the overall mass balance equations of reactive systems because S(R- = 0, i.e., there is no net mass gain or loss as a result of chemical reactions.

Probably the most frequently made observation is the change in mass of a test-piece. This may take the form of a mass gain or a mass loss. 

Mass-gain determinations are most common in studies of the extent and rate of oxidation or scaling at elevated temperatures (see ASTM G54 1984). 

Thermogravimetry (TG) is a measure of the thermally induced weight loss of a material as a function of the applied temperature [45]. Thermogravimetric analysis is restricted to studies that involve either a mass gain or loss, and it is most commonly used to study desolvation processes and compound decomposition. The major use of TG analysis is in the quantitative determination of the total volatile content of a solid. When a solid can decompose by means of several...

Because the choice of a particular derivative is a compromise between good mass spectrometric characteristics and good chromatographic characteristics such as volatility, stability, and absence of interference, heptafluorobutyryl derivatives have been preferred to trimethylsilyl ethers because of their higher mass gain, which made interference less likely to occur, and their favorable fragmentation... 

This method involves preparation of a standard curve by equilibration of a specific amount of dry standard material in duplicate or triplicate over different saturated salt solutions. The standard curve is a plot of aw versus water content of the standard material. The standard must be stable during reuse of the material, and the chamber used should be exactly the same as will be used later. For the measurement, the size of each standard should be in a controlled narrow range, (e.g., —1.6 0.1 g). Once the standard curve is made, dry aliquots of the same mass of standard are equilibrated over a large quantity of the food material (-10 to 20 g). The moisture content of the standard material is then measured (e.g., by mass gain) and aw is estimated from the standard curve (Vos and Labuza, 1974). This method avoids preparation or storing of saturated salts for each determination moreover, use of a standard shortens the equilibration, thus requiring less time for measurement, and less abuse of temperature for sample as well as standard. 

The relative amounts of sample and standard material have to be different because the moisture transferred from the food sample to the standard (characterized by the mass gain of the standard) must not result in a significant change in the vapor pressure maintained by the sample. Essentially, the sample replaces the salt solution in the Basic Protocol to create constant aw in the closed chamber. 

The product was created with the intended use of treatment for various conditions resulting from menopause in women. Female athletes used the product to obtain the effects of testosterone while utilizing the somewhat protective qualities from virilization of estrogens. Males who are prone to prostate problems, hair loss, and serious acne use reported the product allowed them to reap the rapid mass gains of testosterone use while minimizing these effects. 

Women often reported use of Winstrol Depot. "Usually" those who reported 25mg 2-3 times weekly or a single weekly 50-mg injection use reported no virilization effects. (I have known many women who have utilized 50-100mg daily of this drug) Stacked with Oxandrolone and/or Durabolin, women achieved excellent quality lean mass gains. 

Sometime in the 80 s athletes found out Zeranabol had anabolic activity. Since it is actually a form of estrogen, the drug increases nitrogen retention. IGF-1, GH, and Insulin secretion increases are also realized for the same reason. The result is some lean mass gain with high water retention. For the most part, users have realize HPTA function suppression at extreme rates, gyno, fat deposits, and head-aches. Oh, did I mention liver damage ...
