Purpose: Commonly used diffusion weighted (DW) imaging such as DW spin echo (SE) type echo planar imaging (DW-SE-EPI) is known to be a snapshot-like acquisition and to have a relatively high signal-to-noise ratio. Spiral MRI sequence (SPIRAL) has characteristics similar to these of EPI, but it has rarely been used for diffusion-weighted imaging (DWI). In vivo DW-SPIRAL of the rat brain has almo...

This paper addresses DW design problems, with the goal of improving the DW logical design process. Some of the existing work in transformation oriented methodologies for DW design construct the DW starting from an EntityRelationship model of the source database, and arrive to a conceptual or highlevel-logical dimensional model of the DW. We propose a mechanism for obtaining the DW logical schem...

the essential oils and aromatic water, known as arak in traditional iranian medicine, comes from the aerial part of teucrium persicum boiss., which is grown in fars province located in iran. the samples were collected in summer and the oils and aromatic water were obtained through steam distillation. the chemical composition of the oils was analyzed using gc-ms. an analysis of the chemical prof...

Efforts to assess forest ecosystem carbon stocks, biodiversity, and fire hazards have spurred the need for comprehensive assessments of forest ecosystem dead wood (DW) components around the world. Currently, information regarding the prevalence, status, and methods of DW inventories occurring in the world's forested landscapes is scattered. The goal of this study is to describe the status, DW c...

Development, homeostasis and regeneration of tissues result from a complex combination of genetics and mechanics, and progresses in the former have been quicker than in the latter. Measurements of in situ forces and stresses appear to be increasingly important to delineate the role of mechanics in development. We review here several emerging techniques: contact manipulation, manipulation using ...

the impact of de-oiled and dried two-phase olive mill waste (dw) amendment on the sorption,degradation, leaching, and persistence of the herbicide terbuthylazine in a mediterranean agricultural soil were studied under laboratory and long-term field conditions. the results are compared with those of a previous study, where the intermediary by-product of the olive-oil processing technology (ow) w...

Walters The IBM zEnterpriseA 196 (z196) system, announced in the second quarter of 2010, is the latest generation of the IBM System zA mainframe. The system is designed with a new microprocessor and memory subsystems, which distinguishes it from its z10A predecessor. The system has u...
