End products are returned in all or in part to the country of the supplier of plasma. The costs involved in establishing a contract fractionation program are substantially less than those involved in establishing and operating a fractionation plant. In the absence of a local fractionation plant, products originating from plasma collected locally can be made available using contract fractionatio...

In the fields of researches associated with plant layout optimization, the main goal is to minimize the costs of pipelines and pumping between connecting equipment under various constraints. However, what is the lacking of considerations in previous researches is to transform various heuristics or safety regulations into mathematical equations. For example, proper safety distances between equip...

Information management is one of the most significant issues in nowadays data centers. Selection of appropriate software, security mechanisms and effective energy consumption management together with caring for the environment enforces a profound analysis of the considered system. Besides these factors, financial analysis of data center maintenance is another important aspect that needs to be c...

ON OPTIMAL POLICIES FOR MULTI·REPAIR·TYPE MARKOV MAINTENANCE MODELS Yukio Hatoyama Tokyo Institute of Technology (Received April 6, 1978) This paper treats an extension of an optimal machine maintenance model with Markovian deterioration introduced by Derman. The system consists of an operating machine whose deterioration is Markovian, a finite number of identical spare machines, and several ty...

Abstract Feedwater to Euroa Water Treatment Plant contains increasingly high levels of natural organic matter (NOM) which were determined cause its strong earthy odour. A multidisciplinary approach was used evaluate the coagulation process better remove taste and odour (T&O) causing organics from water supplied local towns. Such NOM require elevated doses coagulant for removal, accounting a...

We tested whether growth and maintenance costs of plant organs vary with environmental stress. Quercus ilex L. seedlings from acorns collected from natural populations in the northern Iberian Peninsula and in a lower elevation and putatively less stressful habitat in the southern Iberian Peninsula were grown in pots under the same conditions. Growth and maintenance respiration were measured by ...
