The problem we consider is a practical multiple-period wood procurement planning problem in the Eastern Canadian context. The forest cut blocks are large and heterogeneous; they have different densities and the diameter of the trees varies. This is a difficult forest management problem because it integrates two related problems: the forest bucking problem with a cut-to-length (CTL) bucking syst...

Background: Succinylcholine is the most anesthetic drug used to muscle relaxation in emergency endotracheal intubation. Unfortunately it can have serious side effects. The perpose of our study was to comparison of Atracurium + Alfentanyl with succycholine.

Optimal bucking methods were applied to two operational sites of the Nasu-machi Forest Owners’ Co-operative to maximize profits, with and without taking log size into consideration, and to maximize revenues considering a new subsidy system and higher unit prices of smallsized logs. Corresponding optimum extraction rates and small-sized log prices were examined. Extraction rates from stands usin...
