most specialists in the field of foreign language teachingconsiderreading skill as an interactive process between the reader’s prior knowledge and the text.accordingly, the activation of prior knowledge for an effective comprehension is very important. it is generally agreed that the pre-reading phase is the stage where this type of interaction and activation may be enhanced throughcertain stra...

multiphase flows are commonly encountered in oil and gas industries. the transport of multiphase flow causes the formation of slug, the increase of pressure drop and the possibility of phase changes therefore, a set of simulation runs was performed to predict flow regimes in a horizontal pipeline, and the results were compared with the baker chart. the effects of small downward inclinations of ...

1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...

Nonlinear kinetics of both spinodal decomposition at early stages, and the dissolution of homogeneities formed during spinodal decomposition,is studied. Variation of the scattering intensity during a complete cycle consisting of a step temperature change from T i in the one-phase. region to T2 in the two-phase region, a period of spinodal decomposition followed by a temperature drop from T2 bac...

This document provides an update of the WINNER system requirements described in WINNER phase I, considering the latest developments in research, regulation, standardisation, wireless market, and industry. The focus is only on system requirements with impact on the development of a new radio interface concept and design, which is the primary goal of WINNER. Keyword list: WINNER, requirements, se...

Mathematical models for a class of two-phase chemical absorption processes with a single irreversible chemical reaction are presented, as well as an analysis of their dynamical behaviour. Here emphasis is put on the interfacial mass transport which especially in the case of fast reactions must be considered carefully. The resulting models consist of systems of reaction-diiusion equations on the...

We introduce a technique that can be used to model the behaviour of protocols. In our model each process within a protocol belongs to a particular class. A set of rules governs the behaviour of a process within a process class. The rules give rise to a transition system that models the behaviour of the protocol. By exploiting the homogeneous behavior of a process within a particular class it is...
