Davis, Gillon and Matthewson (hereafter Davis et al) argue that “hypothesisdriven fieldwork has led to a more complete and accurate picture of linguistic diversity than has been produced by methods which rely largely on extracting information from existing descriptive grammars”. They discuss five cases to support their conclusion. In this response, I will discuss only one of these cases, since ...

garlic (allium sativuml.) is one of the most important allium spice. from an economic point of view, the dried garlic slices are valuable products. in this research, garlic slices as a thin layer were dried in a laboratory scale hot-air dryer, under air flow of 1.5 m/s, air temperatures of 50, 60 and 70˚c and slice thicknesses of 2, 3 and 4 mm. the mean values of shrinkage of garlic slices obta...

This study investigated the effects of temperature on drying behavior and kinetic features lily scales. A series experiments were carried out at 65, 75, 85 °C to dry scales in a laboratory air-ventilated oven dryer. Drying was found significantly affect times rates. The rate curves suggested that process occurred entirely within descending period. During simulation kinetics, Page Logarithmic mo...

drying is a high energy consuming process. solar drying is one of the most popular methods for dehydration of agricultural products. in the present study, the performance of a forced convection solar dryer equipped with recycling air system and desiccant chamber was investigated. the solar dryer is comprised of solar collector, drying chamber, silica jell desiccant chamber, air ducts, fan and m...

this study determined optimum conditions for drying pomegranate arils in a solar dryer. a cabinet solar dryer was used in active and mixed modes. the response surface method was employed with nine treatments (runs) and a control run (3 m/s air velocity and 2 cm in thickness) and five replications. the bryte cultivar was tested and samples were dried to approximately 10% moisture. drying time, v...

Small particles are of great interest in a variety applications. Spray drying is common technique for particle synthesis, but it limited with respect to sizes below 10 μm. Therefore, new laboratory-scale spray dryer was designed address this issue. A novel aerosol generator consisting piezo crystal swirl chamber obtain droplets the low micrometer range. After and cooling, were deposited molten ...

Drying of spruce, beech, willow, and alder sawdust was examined in a laboratory type dryer. The effect drying air temperature T (25, 60, 80 °C) airflow velocity v (0.01, 0.15, 1.5 m/s) investigated. obtained results demonstrated that have impacts on the sawdust. experimental dehydration data were fitted to theoretical, semi-theoretical, empirical thin-layer models. accuracies models estimated u...

Mercury Levels Lower in Great Lakes, but Still High Although mercury concentrations have decreased about 20% in fish, fish-eating birds, and inland lake sediments across the Great Lakes region in recent decades, levels in top predator fish and wildlife are still dangerously high, and in some places concentrations in some fish and wildlife may now be increasing, according to a new report. Levels...

The current study aims to determine the performance of a rack-type solar dryer. dryer uses heat absorber in form large wave plate and small which is placed collector room. dried material cassava. system used natural air flow due density differences. research was carried out by making two collectors, difference being used, one other wave. test simultaneously between dryers. In this study, result...

A numerical investigation of a solar greenhouse tunnel drier (SGTD) has been performed. In the present study, the geometry of the tunnel roof is assumed semi-circular which is covered with a UV (200μ) stabilized polyethylene film. The simulated SGTD reduces moisture of copra from 52.2% to 8% in 55 h under full load conditions. A system of partial differential equations describing heat and moist...
