Using the recently proposed ggη effective vertex, we investigate the production of η from gluon fusion in polarized pp collisions. We show that by measuring ALL in η ′ production, one can extract the polarized gluon distribution ∆G(x,Q) at Q ∼ 1GeV and in a wide range of x.

Still another attractive book attempting to describe the cause, course, and current treatment of diabetic retinopathy is now available. This particular volume represents papers presented at a Symposium held in 1972. Of course the thinking on the subject of diabetic retinopathy is in a rapidly changing phase, and therefore comments and discussion, even from serious-minded persons, are soon outda...

Production function studies have mainly been directed at the formal health care sector, in particular hospitals. Health production function relating medical and/or non-medical health inputs to good health, however, have not been intensively investigated. This paper explores the possibility of employing a health production function to examine the relationship between preventive health programs a...

in the market for factors of production usually the equilibrium will be stablished on the based of the equality between the value of marginal products of output and their relative price level. on the other hand the value of marginal product of output is a function of observed rate productivity of output and the market capacity of factors of production. thus the fluctuation in the rate of produc...

The ratio estimator of the markup is output elasticity for a flexible input to that input’s cost share in total revenue. We highlight identification and estimation issues pertaining this estimator, when firm-level prices are not observed. If revenue used place elasticity, then profit maximization implies identically equal one, thus uninformative about markups. Concerning elasticities: with only...

Inventory management seeks to improve manufacturing by contracting inventory costs in a similar fashion raise efficiency and profit. One approach is develop models according actual production systems. Furthermore, governmental policies many countries impose regulations on firms fulfill the growing demand for reduction carbon emissions. Warm-up familiar concept industrial applications. It allows...
