MASS TRANSFER MODEL BUILDING IN DRYING
Drying Technology, 1993ABSTRACT The objective of much experimentation in drying is to build or discover a suitable model for a drying system. In this study, an attempt is made to formulate an approach to the problem of iteratively improving models, guided by the inefficiences of an initial tested model.

A procedure has been developed for the determination of the dry mass of a pure protein preparation dissolved in one electrolyte. The procedure not only renders the concentration (in g/l), but additionally gives the partial specific volume of the protein (in ml/g).

Abstract 1. To measure the value of the dry mass of Purkinje cerebellar cells, two methods of cell isolation were chosen (‘free hand dissection’ and tissue imprints). The cells isolated by the modified technique of smears with the aid of polyvinyl foil, had a smaller degree of damage.

[Conversion methods of freshwater snail tissue dry mass and ash free dry mass].
Ying yong sheng tai xue bao = The journal of applied ecology, 2010Mollusk biomass is usually expressed as wet mass with shell, but this expression fails to represent real biomass due to the high calcium carbonate content in shells. Tissue dry mass and ash free dry mass are relatively close to real biomass. However, the determination process of these two parameters is very complicated, and thus, it is necessary to ...

Mass Transfer Properties for the Drying of Pears
2014Portugal is among the tropical countries that have a long tradition of drying fruits, such as figs, grapes or pears. The knowledge of the transfer phenomena involved in drying processes is of major importance for the design and optimization of the most adequate operating conditions.

Heat and Mass Transfer in Spray Drying
Journal of Fluids Engineering, 1955Abstract The heat and mass-transfer phenomena to and from droplets during spray drying are discussed. Evaporation from pure liquid drops and drops with solids present in quiescent and in moving air are considered. The problem of evaporation at high air temperatures is noted.

Simulation of Wear Through Mass Balance in a Dry Contact
ASME/STLE 2004 International Joint Tribology Conference, Parts A and B, 2004Numerical investigations are carried out to simulate wear and the analysis of these simulations leads to proposing an original new wear law that takes into account interfacial particles in the contact. A 3D Discrete Element Model is presented that simulates the detachment of particles, their flow in the contact and their ejection. It shows that a layer

An integrator for measuring the “dry mass” of cells and isolated components
Experimental Cell Research, 1956Abstract In general the total “dry mass” of a cell may be determined by measuring first the average optical path difference of the cell in water and then multiplying this value by the cell projected area. It is shown that this product can be measured directly provided that the maximum optical path difference of the cell in water is less than about 0 ...

HEAT AND MASS TRANSFER IN IMPINGEMENT DRYING
Drying Technology, 1993ABSTRACT In industrial drying applications, efficient transfer of heat and mass between a drying medium and the material being dried is very critical for the overall economics of the operation. Impinging jets are therefore widely used for their enhanced tmnsport characteristics, especially for drying of continuous sheets of materials such as paper and ...

Determination of the dry mass of tissue sections by interference microscopy
Journal of the Royal Microscopical Society, 1965SYNOPSISUnder certain conditions the relationship between the optical‐path difference and the light intensity in an interference system is identical for both even field and interference fringes. This principle has been utilised to determine the absolute value of optical‐path differences in interference contrast (even field) for estimation of the dry ...
