We study a periodic-review production/inventory control problem where both the supply of raw material and demand for the finished product are exogenous and random, the raw material can be stored for future use, can be purchased from or sold to an outside market. We study both the lost sales and backlogging cases under both strict convex and linear raw material purchasing/selling costs. Convexit...

The demand for herbal raw material has increased tremendously due to renewed interest in plant-based medicines, especially in developed countries. This has led to the indiscriminate cutting and collection of medicinal plants from natural resources resulting in depletion of natural resources and in some cases extinction of species. In the recent past, aseptically grown raw material and cell cult...

The current standard and open formats for forensic data describe whole disk and memory image properties, but do not describe the products of detailed investigations. We propose a simple canonical description of digital evidence provenance that explicitly states the set of tools and transformations that led from acquired raw data to the resulting product. Our format, called Digital Evidence Exch...

We report the results of an analysis of raw material selection patterns in the assemblages from two Late Pliocene in situ archaeological localities in the Makaamitalu Basin (Hadar, Ethiopia). While the same local conglomerate was used as a raw material source for both archaeological occurrences, different selection criteria are identified. At A.L. 894, selection for quality is subtle and the cl...

This research is about manufacture nanopowder Bioceramics from local materials used Ball Milling for biomedical applications. Source materials for the manufacture of medicines are plants, animal tissues, microbial structures and engineering biomaterial. The form of raw material medicines is a powder before mixed. In the case of medicines, research is to find sources of biomedical materials that...
