Vacuum Drying Characteristics of Some Vegetables
In this research the drying of four kinds of vegetables was investigated in a vacuum dryer. The effect of temperature on drying rate of samples at various temperatures (30, 35 and 45 °C) was studied. Six thin-layer drying models were fitted to drying data and suitable model was selected from them. Then effective moisture diffusivity and ...
متن کاملRadio Frequency/vacuum Drying of B.c. Softwoods; Preliminary Experiments
Five exploratory drying runs were carried out in a commercial size (23 m3), radio frequency/vacuum hardwood kiln. The species investigated were Pacific coast hemlock, Douglas-fir and western red cedar of different sizes and grades. Evaluation of the dried lumber showed that the three species can be dried in very short times and low amount of degrade irrespective of thickness with the exception ...
متن کاملConstructing an Ultra-High Vacuum Chamber and a Radio Frequency Helical Resonator for Trapping Ions
We describe the construction of an ultra-high vacuum (UHV) chamber and a radio frequency helical resonator for use in co-trapping atomic and molecular ions. Cleaning procedures for the in-vacuum components are provided. These procedures give positive results in cleaning copper electrodes. The thesis also provides general UHV construction techniques and design choices for our UHV chamber. For th...
متن کاملfocus on communication in iranian high school language classes: a study of the role of teaching materials in changing the focus onto communication in language classes
چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
15 صفحه اولThe complexity of tangent words
A smooth curve is a map γ from a compact interval I of the real line to the plane, which is C∞ and such that ||γ ′(t)|| > 0 for any t ∈ I (this last property is called regularity). Any such curve can (and will be considered to) be arc-length reparametrised (i.e. ∀t ∈ I, ||γ ′(t)||= 1). We can approximate such a curve by drawing a square grid of mesh h on the plane, and look at the sequence of s...
