This article proposes to decide on the impact of external and internal factors (competitive forces strategic capabilities) competitive choices (pure or hybrid). Using a sample Tunisian companies operating in manufacturing industry, results show that face competition’ intensity, opt for hybrid strategies at expense pure ones only when they have strong combined capabilities. However, st...

  In this study we investigated the bronchodilatory and anticholinergic effects of the aqueous extract (AE), brewed extract (BE) and ethanol extract (EE) of Polygonum avicular in comparison with saline (S) on isolated tracheal chains of the guinea pig. Due to the probable confounding effect of ethanol in the EE, the effects of this extract were also compared with 96 % ethanol. None of the plant...

A short-term electricity market coordinated by a system operator provides a foundation for a competitive electricity market. In this setting, transmission congestion contracts are equivalent to perfectly tradeable physical transmission rights. With such contracts to allocate transmission benefits, it would be possible to rely more on market forces, partly if not completely, to drive transmissio...

Recent empirical studies have focused attention on the interplay in multi-host systems of parasite-mediated apparent competition and direct competition between hosts. However, theoretical investigation of such systems has been hindered by the onset of algebraic intractability with the increase in system dimensionality. In this paper we circumvent this problem by using a geometric approach in wh...

Today, numerical simulation can be used as a suitable tool to measure large quantities that are very expensive and, in some cases, impossible to measure. One of the important issues in predicting rock mass boreability in excavation with full face tunnel boring machines is estimating the discchr('39')s forces for rock cutting. For this purpose, the linear cutting test is  employed. However, limi...

Communication and information technologies (CIT) have made possible a multitude of ways in which Australian universities can deliver their educational services. At the same time, universities face increasing pressure from new and emerging markets to diversify their delivery and to improve their efficiency. These pressures are the result of various policy, competitive, demographic and technologi...

Calcium-silicate-hydrate (C-S-H) is the major binding phase responsible for strength and durability of cementitious materials. The cohesive properties of C-S-H are directly related to the intermolecular forces between its layers at the nanoscale. Here, we employ free energy perturbation theory (FEP) to calculate intermolecular forces between crystalline C-S-H layers solvated in aqueous medium a...
