By distinguishing between producible and nonproducible public goods, we are able to propose a general equilibrium model with externalities that distinguishes between and encompasses both the Starrett [1972] and Boyd and Conley [1997] type external effects. We show that while nonconvexities remain fundamental whenever the Starrett type external effects are present, these are not caused by the ty...

In this paper‎, ‎we introduce a new type of graph contraction using a special class of functions and give a best proximity point theorem for this contraction in complete metric spaces endowed with a graph under two different conditions‎. ‎We then support our main theorem by a non-trivial example and give some consequences of best proximity point of it for usual graphs.

preterm contraction of uterus is a main cause of miscarriages and preterm labour. euphorbia known as ferphion in iranian traditional medicine texts like al-hawi, is reported for prevention of preterm labour. therefore, the objective of this research was to investigate the effect of euphorbia spinidens bornm. ex prokh. on motility of rat uterus. uterine horns were isolated form non-pregnant fema...

Excitation-contraction (E-C) coupling was investigated in rat hearts 6 wk after induction of myocardial infarction (MI) by ligation of the left coronary artery. Heart weight was increased by 74% and left ventricular end-diastolic pressure was 23 +/- 2 mmHg in MI compared with 8 +/- 2 mmHg in sham-operated controls (Sham, P < 0.001). Cell shortening was measured in voltage-clamped myocytes at 36...
