Regarding the nutritional value and availability of acorns in west and southwest of Iran, the effects of partial substitution of wheat flour with acorn flour was investigated. Wheat flour was replaced by treated acorn flour in the formulation of sponge cake and the quality characteristics were evaluated. Density of cakes was increased with increasing the acorn flour. As the substitution degree ...

In this paper we develop an inventory model, to determine the optimal ordering quantities, for a set of two substitutable deteriorating items. In this inventory model the inventory level of both items depleted due to demands and deterioration and when an item is out of stock, its demands are partially fulfilled by the other item and all unsatisfied demand is lost. Each substituted item incurs a...

Reaction of dialkyl acetylenedicarboxylates 1a-c andpyrrole derivatives 2a-e in the presence of triphenylphosphite (TPP) was investigated and the effect of the pyrrole substitution was established. Diastereoselectivity is observed with pyrroles, 2a,b, yieldingphosphonate ester derivatives 3a-f and 4,and their relative configuration is determined by 1H/13C and 31</...

(Abstract) According to one theory, consumer-voters mistake the lump-sum aid for matching aid such that the former reduces their tax price of the aided service, generating the substitution effect. This flypaper effect is more likely when both lump-sum aid and matching aid (or equivalent tax-price reducing mechanisms) coexist and there is a high likelihood of interaction between the lump-sum aid...

This paper proposes an explanation of the backward-bending labor supply curve that is not based on the premise that the income effect dominates the substitution effect. Unlike the classical labor supply theory that treats working hours and work effort as being synonymous, this paper treats them as distinct variables in an efficiency wage model. A wage rate increase is shown to give rise to two ...
