the objective of this study was to evaluate different pistachio hullers and determine the proper harvest time of pistachio nuts for hulling. three pistachio hulling machines (helical drum, helical- blade drum, rubber drum) at three harvest times and 15 days interval were evaluated. the hulling efficiency, percentage of damaged nuts, faulty hulled nuts and unhulled nuts were measured at each tim...

Plastics recycling has become a key industry in developed countries, to reduce ecological damage and save non-renewable resources. This paper discusses the concept design of electrostatic separator as test bench for separation different plastics applications. In automotive process, all these waste materials must be processed further re-entering cycle or thermal utilization. The following applic...

The ergometer can be a versatile means of measurement if attachments are developed for special purposes or if attachment is developed for multi-uses. In this study, an ergometer attachment for the measurement of power was designed and the measurement of power and the maximum anaerobic power in swimming was tested. A rotation drum was attached to one pedal of an ergometer. The rotation of this d...

The insertion losses of five neoprene diving hoods varying thicknesses (2 mm–9 mm) were measured in one-third octave bands using a Kemar manikin diffuse broadband noise field. air for both dry and wet hoods. loss was calculated as the sound level each frequency band with hood, minus corresponding without hood. similar ears manikin. Both neither attenuated nor amplified below 250 Hz. Between 315...

In pistachio nuts, aflatoxin is mainly concentrated in the green hull-cracked nuts in the orchard even prior to harvest. However, during the hull-removal process, the hulls of all nuts including the cracked, identifiable nuts are removed causing an important characterization criterion of the contaminated nuts, to be lost. This, in turn, makes it harder to detect the contaminated nuts. However, ...

This article aimed to separate ilmenite (FeTiO3) mineral from tin tailing applying a single splitter IRMS (Induced Roll Magnetic Separator). Ilmenite is the substantial main source for TiO2. work used air table middling feeding. The components of feeding using grain counting analysis were found as follows: cassiterite (48.61%), (21.36%), monazite (18.56%), pyrite (4.60%), zircon (5.85%), quartz...

The treatment of Wastes Electrical and Electronic Equipment (WEEE) is a significant source secondary raw materials. Ferrous non-ferrous metals, electronic equipment, plastics are among these One the most common metals sourced out WEEE stainless steel. Dishwashers sources steel, so large amounts steel can be recovered from them. In this project, dishwashers were submitted to size reduction via s...
