We present an application of the program of groupoidification leading up to a sketch of a categorification of the Hecke algebroid—the category of permutation representations of a finite group. As an immediate consequence, we obtain a categorification of the Hecke algebra. We suggest an explicit connection to new higher isomorphisms arising from incidence geometries, which are solutions of the Z...

We present a three-dimensional modeling study of gas flow in the unsaturated fractured rock of Yucca Mountain. Our objective was to estimate large-scale fracture permeability, using the changes in subsurface pneumatic pressure in response to barometric pressure changes at the land surface. We incorporate the field-measured pneumatic data into a multiphase flow model for describing the coupled p...

introduction: the use of multiple cameras for motion analysis and single joint motion is very difficult and needs high technology in laboratory conditions. detection of single joint motion in kinesthesia and analysis of its changes can be done by one camera at one direction. in this study, we present the validity and reliability of a new prototype simulator system used for motion analysis appli...

background to prevent diseases transmission, infection control in dental offices without reducing the accuracy and dimensional stability of impression materials is very important. objectives the aim of this study was to evaluate the effects of sanosil disinfectants on the dimensional stability of some usual impression materials. materials and methods three types of impression material, namely, ...

abstract statement of the problem: dental prosthesis is usually made indirectly; therefore dimensional stability of the impression material is very important. every few years, new impression materials with different manufacturers’ claims regarding their better properties are introduced to the dental markets which require more research to evaluate their true dimensional changes. objectives: the ...

background: with the technical development, ultrasound tends to overpass its limits and to become the main investigation tool even for situations when it was traditionally considered second best. it is more convenient both for patient and doctor, less expensive and has real diagnostic value. objective: the present paper, and its graphic back-up, are intended as a visual testimony of the fact th...
