چکیده

This study is aimed at investigating the moisture sorption behavior and thin-layer drying kinetics of local sweet potato sada (LSPS) variety slices. The tubers were sliced 3, 5, 7 mm dried temperatures 45, 55, 62°C a constant air velocity 0.6 m/sec in laboratory-scale cabinet dryer. BET (Brunauer, Emmet, Teller) GAB (Guggenheim-Anderson-De Bore) models applied to fit data. Fick’s diffusion equation was used calculate rate effective diffusivity. Our current result reveals that LSPS exhibited an isotherm with sigmoid (type II) shape, model more goodness than clarify adsorption LSPS. time increased increasing slice thickness but reduced temperature. for decreased increase loading density two different shapes (French cut cube cut) also affected constant, which density. Using statistical parameters, five findings indicated logarithmic 45-55°C Page most suitable explaining diffusivity temperature, ranging from 7.10 × 10 − 11 id="M2"> 1.55 m2/s over temperature range studied. activation energy thickness, values 5.55 7.39 kJ/mol 3 5 slices, respectively. suggested sample on dryer trays affect

since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
