In this article, we analyze the application of options contract in the special commodity supply chain such as fresh agricultural products. This problem is discussed from the point of the retailer. When spot market and future market are both available, we discuss how the retailer chooses the optimal production. Furthermore, overconfidence is introduced to the supply chain of the fresh agricultur...

Abstract Cocoa ( Theobroma cacao ) seedlings are very sensitive to water stress during the nursery stage and early field establishment. Sawdust, carbonated rice husk, compost in following ratios (i) 60: 40: 0 – M1, (ii) 30: 10 M2, (iii) 20: 20 M3, (iv) 10: 30 M4, (v) 0: 40 M5, (vi) topsoil M6 as control were used investigate effect of growing media, stress, re-watering on growth, dry matter pro...

Lamport’s Happened-before relation is fundamental to coordinating actions in asynchronous systems. Its role is less dominant in synchronous systems, in which bounds are available on transmission times over channels. This paper initiates a study of the role that time bounds play in synchronous systems by focusing on two classes of problems: Ordered Response, in which a triggering event must be f...

INTRODUCTION The chemical industry is a much safer place to work than many industries with fewer inherent hazards. Nevertheless, almost all the accidents that have occurred need not have occurred.

The aim of present study was to evaluate the effects of drought stress on net photosynthesis rate (Pn), stomatal resistance, water use efficiency (WUE) and biomass (BM) of six maize (Zea mays L.) hybrids. Drought stress applied by withholding water supply at 4-5 leaf stage (S1, vegetative stage), anthesis (S2, reproductive stage), and dual stress condition (S3, combination of vegetative and rep...
