THE RESULTS of experiments on the potassium loss in nerves during stimulation have led to no definite general conclusion. Fenn (‘38) working with the myelinated nerves of cats and frogs obtained no significant loss of potassium. Cowan ('34) using the unmyelinated nerves of the spider crab, Maia squinado, obtained an appreciable loss of potassium during fZteen minutes of stimulation. His method,...

IT has been suggested (Huxley, 1927; Shaw, 1928) that in various animals, such as some Crustacea which show disharmonic growth, there exist growth centres correlated with the active growth of specific organs or regions. Also that the growth of neighbouring parts is correlated with the growth of the heterogonic organ. In Maia squinado (Huxley, 1927) and Inachus dorsettensis (Shaw, 1928) the grow...

Keywords: Bimetric space Fixed point Coincidence point Two-point boundary value problem a b s t r a c t In this paper, we introduce a generalized contraction of Krasnoselskii-type using auxiliary functions, and obtained some sufficient conditions for existence and uniqueness of fixed point for such mappings on bimetric spaces. We also establish a result on coincidence point of two mappings, and...

The aim of this paper is to identify the effect of financing constraints on the employment decisions of firms. We present a theoretical model that determines the optimal use of fixed term and permanent contracts in the presence of financing constraints. We then estimate the effect of financing constraints on the dynamics of fixed-term employment contracts versus permanent employment contracts f...
