For any partition of {1, 2, . . . , n} we define its increments Xi, 1 ≤ i ≤ n by Xi = 1 if i is the smallest element in the partition block that contains it, Xi = 0 otherwise. We prove that for partially exchangeable random partitions (where the probability of a partition depends only on its block sizes in order of appearance), the law of the increments uniquely determines the law of the partit...

W model a situation in which two retailers consider launching an “Advance Booking Discount” (ABD) program. In this program, customers are enticed to precommit their orders at a discount price prior to the regular selling season. However, these precommitted orders are filled during the selling season. While the ABD program enables the retailers to lock in a portion of the customer demand and use...

C a retailer who sells perishable seasonal products with uncertain demand. Due to the short sales season and long replenishment lead times associated with such products, the retailer is unable to update demand forecasts by using actual sales data generated from the early part of the season and to respond by replenishing stocks during the season. To overcome this limitation, we examine the case ...

Purpose: The main objective of this study was development of determination of phase fraction methodology in cast magnesium alloy containing aluminum and rare earth elements. Design/methodology/approach: The study was conducted on magnesium alloy containing 4 %wt. aluminum and 4 %wt. mixture of rare earth elements (mischmetal) in the as-cast condition. The mischmetal includes cerium, lanthanum, ...

Conservative mostly used upto six years age, while for children more than 12 surgery usually preferred. We extended hip spica cast till 10 This study evaluates results followed by age.Methods: Study was done GMC Doda April 2019 Mar...

Association of genetic polymorphism in the calpastatin (CAST) gene with average daily gain was examined in Iranian purebred Kurdi sheep. The genotypes for CAST were determined by the PCR-SSCP method. Blood samples were collected from 84 purebred Kurdi sheep belonging to the Kurdi Breeding Station located in the Khorasan province, north-east of Iran. Extraction of genomic DNA was based on the Gu...

High accuracy dental impression is usually a first step during fabrication of indirect restorations that have to be seated in or on prepared teeth. The dimensional stability of the impression material could have an influence on the accuracy of the final restoration. Elastomeric materials (additioncured silicones and condensationcured silicones) are most frequently used as the impression materia...

The relation between muscle atrophy and bone osteoporotic changes due to immobilization are still not completely understood. This study tried to throw more light on this association and to probe the ability of amino acid Lleucine, to limit these changes in a trial to accelerate rehabilitation. Adult male Albino rats weighing 180-210 g were used and classified into three groups, I-control group,...
