In order to corroborate the efficiency of PET bottle inspection equipment coupled with mass spectrometry detection, a method for determination of BTEX presented in the interior of returnable PET bottles was developed and validated. It was verified that the method was able to detect BTEX compounds in the range 0.1-10mL of gasoline.

The classical economic order quantity model is extended to the case where items may be acquired from various suppliers. It assumed that any lot size received a supplier contains perfect and imperfect quality items. percentage of in random variable having known probability distribution. are detected through 100% screening process conducted at start inventory cycle. When concluded, sold one batch...

An order level inventory system for deteriorating items has been developed with demand rate as a ramp type function of time. The finite production rate is proportional to the demand rate and deterioration rate is time proportional. The unit production cost is inversely proportional to the demand rate. The model with no shortage case in inventory is first solved. The inventory shortage is discus...

In this article, we extend Cheng, Zhang and Wang [17] model studied pricing strategies in marketing. The objective is to find the optimal inventory and pricing strategies maximizing the net present value of total profit over the infinite horizon. It is important to control and maintain the inventories of deteriorating items for the modern corporation. We will discuss two models: one is without ...

BACKGROUND Latex allergy has emerged as a major cause of allergic reactions in health care workers. However, information is limited regarding the diagnostic methods available.

BACKGROUND The prevalence and predictors of functional status and disability of elderly people have been studied in several European countries including Spain. However, there has been no population-based study incorporating the International Classification of Functioning, Disability and Health (ICF) framework as the basis for assessing disability. The present study reports prevalence rates for ...
