“This paper considers advance order strategies in a two-echelon supply chain with one supplier and multiple buyers for seasonal products. We study how advance strategies MLN2238 nmr affect the interactions between the supply chain members. In contrast to much of the literature, we specifically consider the supply chain with multiple buyers by introducing
a demand function under uncertainty. Furthermore, we present two main different advance order strategies. We assume that exactly one of the multiple buyers has the ability to make an advance order before the selling season (we call this buyer the natural leader). In one strategy, the natural leader can only order products one time. The model shows that, below a threshold level of demand uncertainty, the supplier can benefit from providing adequate pricing incentives to entice the natural leader to order products before demand information is revealed. In another one, the natural leader can order products two times, we find that the supplier always can gain more Selleckchem ALK inhibitor profit from this advance order strategy. Our results show that the first advance order strategy is easier to control but has
more strict constraint on coefficients of variation, while both two advance strategies bring more flexibility to the supply chain. (C) 2009 Elsevier Inc. All rights reserved.”
“Food plants are important sources of iodine, an essential nutrient required for the synthesis of thyroid hormone in humans. Understanding iodine metabolism in plants is
important for tackling iodine deficiency, a serious micronutrient deficiency in the world. Elucidation of iodine metabolism in plants is also important for understanding biogeochemical iodine cycling because plants absorb iodine from the soil and emit considerable amounts of gaseous iodine compounds into the atmosphere. HAMLESS TO OZONE LAYER (HOL) family proteins found in plants have been reported to synthesize methyl halides, including methyl iodide, from halide ions and S-adenosyl-L-methionine (SAM). Here, we report the kinetic analysis of two rice HOL proteins, named OsHOL1 and OsHOL2. learn more Recombinant OsHOL1 and OsHOL2 proteins synthesized methyl iodide from an iodide ion and SAM. Kinetic analyses of the recombinant proteins showed that methyltransferase activities toward iodide ions were highest among the examined substrates-bromide, chloride, and thiocyanate ions. These results suggested that OsHOL1 and OsHOL2 are involved in iodine metabolism in rice and contribute to methyl iodide emissions from rice.”
