This paper presents a dynamic programming (DP) model of operating a nuclear power plant (NPP). In each period the operator decides whether to run the reactor, to shut it down for preventive maintenance or refueling, or permanently close the plant for decommissioning. The maximum life of a NPP is determined by the length of the operating license issued by the Nuclear Regulatory Commission. The o...

The Plant Diagnostic Lab at Auburn University receives plant problem/disease samples for diagnosis and soil samples for nematode analysis from all sections of the state. The Plant Diagnostic Lab at Birmingham receives predominantly horticultural samples for disease/problem diagnosis from Jefferson County and adjoining counties. Records from both labs are often used to document plant disease occ...

Reliable and continuous operation of ships is vitally important to the decision-makers. Driven by rising cost newbuilding ships, maintenance actions are needed on existing ensure safe enduring service beyond their initial design life. Extending ship life can provide economic operating profit promote sustainability. Meanwhile, during extended may involve higher failure risk additional expenditur...

rosa hybrida l. is an important commercial cut flower. salicylic acid (sa) and calcium chloride (cacl2) act as endogenous signal molecules responsible for growth parameters in plants. the aim of this study was to evaluate the effects of preharvest sa and cacl2 treatments in extending the vase life of cut rose flowers. therefore, a factorial experiment based on completely randomized design with ...

the effect of eight cucumis l. (cucurbitaceae) genotypes, including native cucumber genotypes (hormozgan, bushehr and gilan), greenhouse cucumber genotypes (girtap, negeen, sepehr and pouya) and armenian cucumber (cucumis melo var. flexuosus) was studied on the life table and population growth parameters of aphis gossypii glover to evaluate antibiosis resistance. the experiment was conducted at...

the aim of this study was the better assessment of the relationship of pulsing treatment of gibberellic acid as an anti-senescence agent and holding in sucrose as a carbohydrate supply resource on improving some qualitative and physiological attributes of cut rose flower cv. velvet. hence, an experiment involving the pulsing treatment with gibberllic acid (ga3) at 0, 20, 40 and 60 mg l-1, for 2...

abstract. vegetation of each region is one of the most important phenomena of nature and is the best guide to judge about the ecological sciences of that region because the plants are resistant organisms that have endured the long term conditions of all kinds of environmental conditions for a long period of time and have adapted with environmental stresses. therefore floristical investigation o...

the present survey deals with the floristic study of dalab woodlands, located in manesht and ghelarang protected area, western iran. it covers an area of 4335 ha. in total, 224 vascular plant species belonging to 46 families and 156 genera were identified. the largest families are asteraceae (29 species), fabaceae (23 species), poaceae (22 species), and apiaceae (18 species). astragalus (13 spe...
