BACKGROUND: The purpose of this study was to evaluate the sensitometric characteristics of Ultraspeed, Ektaspeed Plus and Insight dental radiographic films using manual and automatic processing systems. METHODS: In this experimental invitro study, an aluminum step-wedge was used to construct characteristic curves for D-, E- and F-speed radiographic films (Kodak Eastman, Rochester, USA). All fil...

The extraction and processing of starch from agricultural commodities is one of the most important agro-industries world wide. By the early 1990s, global production of starch probably exceeded 38 million metric tons (mmt) per year for a market value of at least $11 billion. In Asia, starch production was about 16 mmt and demand for starch by food and non-food industries was growing by 5-10 perc...

Colour and texture are important parameters in foods processing industries. Both these two factors represent meaningful visual stimuli and can be represented by a model for quality control of the products. Some food processing industries give emphasis on the coloury compounds towards quality of the food items. Intensive processing in complex controlled environments of tea fermentation requires ...

Food waste and food processing wastes which are abundant in nature and rich in carbon content can be attractive renewable substrates for sustainable biohydrogen production due to wide economic prospects in industries. Many studies utilizing common food wastes such as dining hall or restaurant waste and wastes generated from food processing industries have shown good percentages of hydrogen in g...

The purpose of this study was to establish the validity and reliability of a hydrostatic weighing method using total lung capacity (measuring vital capacity with a respirometer at the time of weighing) the prone position, and a small oblong tank. The validity of the method was established by comparing the TLC prone (tank) method against three hydrostatic weighing methods administered in a pool....

Nondestructive evaluation (NDE) techniques are widely used in manufacturing and service industries for quality assurance and related applications [1]. Depending on the sophistication of a given NDE procedure, the inspection result can be in a form of a simple go/no-go indication, an amplitude readout, a list or a table of measurements, a twodimensional figure, or an image which correlates test ...

— Seven important variables having profound impact on the ability of a mixing tank to suspend particles have been investigated using computational fluid dynamics (CFD) technology. The results obtained from this study can be applied across a broad range of industries such as the chemical, biochemical, petrochemical and mineral processing industries. Finally, a design template incorporating the o...

Laccases are an interesting group of multi copper enzymes, which have received much attention of researchers in the last decades due to their ability to oxidise both phenolic and nonphenolic lignin-related compounds as well as highly recalcitrant environmental pollutants. This makes these biocatalysts very useful for their application in several biotechnological processes, including the food in...
