Current study investigates the effect of two alternative media NPK (20-5-20) fertilizer and NPK plus macrophyte (M+NPK) compared to the commercial medium (WC) under growth rate and physiological parameters in batch culture mode (2-L), and verifies whether the use of fertilizer (NPK) and macrophyte (Eichhornia crassipes) would be a good tool for Haematococcus pluvialis culture in the laboratory....

OBJECTIVE The objective of this study was to examine the predictive relationships between employee health risk factors (HRFs) and workers' compensation (WC) claim occurrence and costs. METHODS Logistic regression and generalised linear models were used to estimate the predictive association between HRFs and claim occurrence and cost among a cohort of 16 926 employees from 314 large, medium an...

In this study, from the user’s perspective, a spare ordering policy for replacement of a non-repairable product/one-unit system, which with finite useful lifetime limit under a rebate warranty, is developed. The spare unit for replacement is available only by an order and the lead-time for delivering that spare is random. By introducing the gain due to rebate warranty, and the costs due to orde...

Motivated by the quasi-renewal approach in the preceding chapters which emphasized the importance of improved repairs during warranty, in contrast to a replacement, the present chapter analyzes the impact of degree of repair for second-hand products employing quasi-renewal processes. In general, the significant factors which contribute to warranty cost analysis of second-hand systems are age, u...
