Today considerable consumer interest has risen towards the use of herbal hygienic and cosmetic products. Lavender oil is a well-known essence with uses in the treatment of alopecia, dandruff and scalp hair re-growth, as well as possessing antimicrobial, antiviral and antifungal effects. Hence, this study was undertaken to formulate and assess the efficacy of a new clear liquid hair shampoo cont...

Product Market Regulation and Endogenous Union Formation We contribute to the growing literature which aims to link product market regulation and competition to labor market outcomes, in an attempt to explain the divergent US and continental European labor market performance over the past two decades. The main contributions of this paper are threefold. First, we show that the choice of bargaini...

We investigate some aspects of proof methods for the termination of (extensions of) the second-order λ-calculus in presence of union and existential types. We prove that Girard’s reducibility candidates are stable by union iff they are exactly the non-empty sets of terminating terms which are downward-closed w.r.t. a weak observational preorder. We show that this is the case for the Curry-style...

By studying the effect of different patterns of demand in an evolutionary selection model this paper shows how product differentiation reduces competitive selection pressure and thus increases the chances for the coexistence of firms. With the example of a duopoly it shows that: (1) a monopoly is the likely outcome of competition in homogeneous products, (2) although product differentiation doe...
