abstract this study aimed at investigating the impact of etymology strategy instruction on the development of vocabulary of iranian intermediate efl learners. etymology, knowledge of origin of words, roots, and affixes, has proved to be a controversial issue and a question of long debate with regard to its impact on the process of vocabulary learning. this study employed etymology strategy in ...
A wetness duration experiment was carried out within a lily field situated adjacent to coastal dunes in the Netherlands. A within-canopy model was applied to simulate leaf wetness in three layers, with equal leaf area indices, within the canopy. This simulation model is an extension of an existing model. It appeared that in most cases leaf wetness started in the uppermost layer followed by the ...
The results of an investigation into the effects of pre-bond moisture absorbed by fibrecomposite substrates prior to bonding with various structural epoxy adhesives are presented. Substrates were bonded in the as-received condition (where substrates had been exposed to atmospheric moisture for periods of greater than three months) and were also bonded in the fully-dried condition (after drying ...
<abstract> <p>Up to 5% of the total olive weight arriving at mill is discarded as leaves. Interest in possible uses these residues growing, because they constitute a potential cheap and abundant source compounds with high antioxidant capacity (TAC) associated phenolic content (TPC) biophenols such hydroxytyrosol (HC) oleuropein (OC), which could be used nutraceuticals or natural sub...
Kim, M.H., Kim, S.M., Kim, C.S., Park, S.J., Lee, C.H. and Rhee, J.Y. 2002. Quality of Korean ginseng dried by a prototype continuous flow dryer using far infrared radiation and hot air. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 44: 3.473.54. This study was performed to examine the effects of infrared (IR)/hot-air combination drying on some quality attributes of Korean ...
background : agaricus blazei mushrooms are one of the most important edible and therapeutic mushrooms, and they contain minerals, vitamins, and amino acids essential for the human body. this mushroom is used raw, dried, and in the form of pharmaceutical products. one of the most important processes after harvesting is drying in order to enhance the quality and the length of maintenance of the p...
in the present study, saffron was dried using a heat pump-assisted hybrid photovoltaic-thermal solar dryer. the effect of different drying air temperatures at three levels (40, 50, and 60oc) and two different modes of the dryer (with and without heat pump system) were investigated on drying behaviour of saffron. after collecting the pertinent data, eleven drying models were used to describe dry...
rice is one of the most widely human consumed agricultural products. for a prevention or diminishing of rice cracking in its milling process, precision control of drying conditions is indispensable. in this research, a thin layer experimental dryer is employed to obtain paddy’s drying kinetics. drying experiments were conducted at five inlet temperatures of drying air of 30, 40, 50, 60 and 70 °...
Response surface methodology was applied for optimization of the sour cherry Marasca juice spray drying process with 20, 30 and 40% of carriers maltodextrin with dextrose equivalent (DE) value of 4-7 and 13-17 and gum arabic, at three drying temperatures: 150, 175 and 200 °C. Increase in carrier mass per volume ratio resulted in lower moisture content and powder hygroscopicity, higher bulk dens...
Botulinum toxin for medical use is diluted to very low concentrations (nanograms per milliliter); when it is preserved by lyophilization, considerable loss of activity can occur. In the present study, conditions that gave > 90% recovery of the toxicity after lyophilization of solutions containing 20 to 1,000 mouse 50% lethal doses per ml were found. Toxicity was recovered upon drying 0.1 ml of ...
