“…5 shows the sorption isotherm for rice at 25" determined in this laboratory and elsewhere. [8][9][10][11][12] In view of the many different kinds and varieties of rice to which Fig. 5 refers, the consistent differences evident in the equilibrium moisture contents at each level of relative humidity, though they rarely exceed 3 %, are not unexpected.…”

Factors affecting the quality of rice during storage in bulk have been investigated, including environmental requirements for minimising microbial growth on the rice by convective and evaporative cooling. In laboratory tests, mould on Caloro rice was first detected after 1+ months' storage at 25" and 75% R.H., but was evident after only one week on rice stored at 25" and 90% R.H. Limiting conditions for drying (and hence evaporative cooling) of rice during ventilated storage were ascertained from a study of the sorption isotherms, determined in the laboratory which indicated that during the last stage an aerating atmosphere of 25" would require to have a humidity of 75 % R.H. or less in order to reduce the moisture content of rice to the desirable final value of 14-15 %.Rice with an initial moisture content ranging between 16 and 22% was used during a full-scale aeration trial in which temperatures at various locations in the rice load (520 tons) were continuously recorded. Since these temperatures varied systematically with ambient temperature, heating of rice through microbial activity apparently did not take place during aeration-a fact confirmed when the rice was unloaded from the storage bin at the end of the aeration trial.A specially designed humidity-controlling device was tested during the last 2f weeks of the major aeration trial and functioned satisfactorily.

“…Since the center of symmetry exists between these two oxygens, hydrogen may locate statistically at the off-centered position. Bond lengths and the estimated bond valences calculatedwith the empirical parametersof Brese and O' Keeffe[4] are given inTable 3. The possible sites for hydrogen are along the O-O pair which is the edge ofvacanttetrahedraas shown inFig.1.…”

A single crystal ofphase G, Mg1.24Si1.76H2.4806was analizedwith synchrotron radiation. The structure ofphase G has close structural similarity to that ofstishovite,SiO2. The valence sum ofthe 0 site is 1.52, indicating the existenceofhydrogen bonding as anion chemistry fir oxygen being OH1/2. The possible sites fr hydrogen are along the O-O edge of vacant tetrahedrabetween corners of Mg06 octahedrawhich are separatedby a distance of 2.654(6) A.[dense hydrous silicate, phase G, hydrogen sites, valence sum]
