research was carried out in 2007 on 7 native summer-ripening apple cultivars grown in kamal abad karaj research station. the 16 year-old plants were grafted onto seed rootstocks. the cultivars were ghandak-e-kashan, golab-e-isfahan, golab-e-kohanz, mashad, assali, ghermez-e-rezaieh and a new cultivar--koli-e-mahallat (syn. escr). the aim of the study was to identify changes in qualitative and q...

This paper presents a method for determining the performance of shuttle-based storage and retrieval systems (SBS/RS) with tier-captive, single-aisle shuttles serving tiers multiple-deep using class-based policy. approach is used in design process SBS/RS upgrading existing SBS/RS. With this approach, it possible to evaluate improvement system by applying The basis calculation continuous-time, op...

Stack allocation and first-class functions don’t naturally mix together. In this paper we show that a type and effect system can be the detergent that helps these features form a nice emulsion. Our interest in this problem comes from our work on the Chapel language, but this problem is also relevant to lambda expressions in C++ and blocks in Objective C. The difficulty in mixing first-class fun...

Parallel NFS (pNFS) extends Network File Sharing version 4 (NFSv4) to allow clients to directly access file data on the storage used by the NFSv4 server. This ability to bypass the server for data access can increase both performance and parallelism, but requires additional client functionality for data access, some of which is dependent on the class of storage used. The main pNFS operations do...

background: despite the growing tendency toward tooth-colored restorations in dentistry, polymerization shrinkage and subsequent marginal microleakage remains a problem. the aim of this in vitro study was to compare microleakage between silorane-based and methacrylate-based composite resins at different time intervals and with different restorative techniques. materials and methods: in this in ...

The Brown Object Storage System (BOSS) provides extensible support for persistence in a distributed multi-client, multi-server environment. BOSS is built on a loosely coupled, asynchronous computation model. One of the artifacts of asynchrony is increased extensiblity. This paper presents the storage class, the means by which the BOSS client interface is extended. The BOSS prototype is complete...
