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...

Abstract Three new ethyltin complexes containing ferrocenecarboxylate, Et 2 Sn(OC(O)Fc) ( 1 ), [(Et SnOC(O)Fc) O] and [EtSn(O)OC(O)Fc] 6 3 ) (Fc = C 5 H FeC 4 have been synthesized by the reaction of diethyltin dichloride with ferrocenecarboxylic acid in presence potassium hydroxide characterized means elemental analysis, FT-IR, NMR spectroscopy, X-ray single crystal diffraction. In solid state...

This article presents the question whether it is correct to classify Günter Grass’s The Tin Drum as a work of magical realism. A brief scrutiny of the elements of magical realism, particularly Authorial Reticence and concept of Hesitation indicates that contrary to the advertisement of certain sources and publishers, this novel in certain circumstances, contradicts and opposes these two indispe...

Chip size distribution is an important quality variable not only for buyers of forest fuels, but also for chipping contractors as it influences both fuel consumption and productivity of chippers. Studies of disc chippers and of drum chippers with closed drums have shown that increased chip target length increases chipper productivity and decreases fuel consumption per ton of chips produced. For...

The boiler drum process is a nonlinear, complex and multivariable process which includes significant time delay. Therefore, the control on the water level in the drum is not easy and ideal. The first objective of this paper is to model the drum water level referring to 210 MW power unit for Nassiriyah thermal power plant. The second objective is to study the water level controller operation wit...

cumin is an annual plant suitable for dry and semi-dry regions. it is harvested at two stages to prevent seed shedding. first, the cumin bushes are harvested by hand or using a scythe. after drying, the cumin bushes are beaten with a stick or trampled using animals or a small tractor. this harvesting method is time consuming, requires intensive labor and is an incomplete threshing process resul...
