The nutritional composition of ogi and its by-products were evaluated with respect to proximate composition, mineral contents and physicochemical properties using standard methods of analysis. The results showed that guinea corn contained more protein (17.52%) than maize (11.24%), but was lower in nitrogen free extract, lipid and minerals (P, K, Na, Fe, Zn and Cu). The predominant content of residue was fibre.

The thermogravimetry (TG) is a technique used in the quality control of foods. In this work the moisture and ash contents
in the rice and by-products (bran and husk), the thermal stability and the gelatinization process by conventional, thermogravimetric
and calorimetric methods were studied. The moisture and ash contents obtained by TG and conventional methods did not present
significant differences. The rice presented higher starch content, while the bran presented higher protein content. The thermogravimetric
data presented the following thermal stability order: rice>bran>husk. The calorimetric curves indicated the gelatinization
of the starch. The kinetic parameters were compatible.

Instrumental neutron activation analysis (INAA) with gamma-ray spectrometry was applied to determine As, Ca, Cd, Cl, Co, Cu, Cr, Fe, Hg, K, Mg, Mn, Mo, Na, Sb, Se and Zn in the Brazilian agroindustrial by-products. These materials are widely used in ruminant feeding. The results obtained were compared with requirement and maximum tolerable concentrations. The general conclusions from the data obtained were: (1) many by-products presented concentrations of some essential elements lower than the requirement concentrations, while in some concentrations of Cr, Fe, Mg and Se exceeded by a little the maximum tolerable concentrations, (2) the elements As, Cd, Hg and Sb, generally considered toxic, showed concentrations lower than maximum tolerable values.

The rate of heat evolution as well as total heat output are strongly affected by other components of hydrating mixture, apart
from neat portland cement, such as slag, fly ash and other industrial by-products; among them the wastes from fluidised bed
combustion (FBC) has been taken into account recently. In this study the calorimeter was applied to follow the early hydration
of cements produced with these materials. They interact with cement paste in a few ways: as set controlling agent and as active
pozzolanic admixtures. Thus the rate of heat evolution/hydration is modified, depending on the composition of clinker and
percentage of waste in the mixture. After the series of measurements for clinker-waste mixture hydrated systems also some
‘model’ mixtures were investigated to separate the effects from particular waste components.
The concentration of 226Ra, 232Th and 40K has been determined by -ray spectrometry. The measured activity in the selected building materials and by-products of coal fired power plants ranges from 21.5 to 91.3 Bq·kg–1, 15.4 to 63.2 Bq·kg–1 and 83.2 to 683.9 Bq·kg–1 for 226Ra, 232Th and 40K, respectively. The results were compared with the reported data of other countries and with the world average activity of soil. The radium equivalent activities values of all building materials are lower than the limit of 370 Bq·kg–1, equivalent to a -dose of 1.5 mSv·y–1. The values of the external hazard index and the internal radiation hazard index are less than unity.

DTA, TG and XRD methods were used for the determination of by-product - obtained during flue gas desulfurization by means
of introduction of dehydration - resisting sludge from water decarbonization system. Analysis results enabled the development
and application of sludge utilization technology by means of semi-dry flue gas desulfurization in 'Siersza' power plant.
