This study proposes a new multi-item inventory model with hybrid cost parameters under a fuzzy-stochastic constraint and permissible delay in payment. The price and marketing expenditure dependent stochastic demand and the demand dependent the unit production cost are considered. Shortages are allowed and partially backordered. The main objective of this paper is to determine selling price, mar...

Calcitriol-mediated hypercalcemia has been reported in malignant lymphomas and granulomatous diseases but not in lung carcinoma. We describe a patient with squamous cell lung carcinoma with hypercalcemia and elevated calcitriol levels. A 60-year-old Caucasian male patient with stage IIIB squamous cell lung cancer developed hypercalcemia at 14.8 mg/dL two years after receiving chemotherapy and r...

Keeping materials in use for a long time is key to reducing primary material demand and environmental impacts of resource use. Recycling yields metals should only be limited by thermodynamically unavoidable losses the remelting processes well-defined scraps. In practice, however, additional dissipative occur due incomplete collection end-of-life products, insufficient waste sorting, contaminate...
