Interconnection is necessary for competition in telephony, but interconnection agreements are difficult to negotiate. With local service competition, entrants usually cannot duplicate the local loop, so interconnection also involves “renting” the incumbent’s local loops. An incumbent may object to being asked to permit use of its infrastructure by its competitors, in order to allow its competit...

BACKGROUND Long healing periods and submerged implant placement are commonly used in the maxilla. This extends the time of oral handicap and makes the use of immediate loading protocols an attractive option. The current clinical literature on direct loading of dental implants in the maxilla is limited. PURPOSE The purpose of this prospective clinical study was to evaluate the clinical outcome...

one of the new methods for electrical powering of the bridge health monitoring systems is applying energy harvesting systems using bridge vibration. in this method, the piezoelectric material is employed for converting mechanical energy into electrical energy. the advantage of this method is based on not implementing the battery charging system. in previous research, some studies have been done...

abstract our religious teachings show a bridge on hell that in the hereafter, all will inevitably pass over it. the bridge path is very slippery and difficult to pass and has obstacles that each is called by particular name. peoplepass overit invariousforms. some fall to the depths of hell, some hop or suspend and a group pass quickly and easily.this paper studies and analyzes these teachings b...

In the asymmetric unit of the title salt, (C(5)H(12)NO)(6)[PMo(12)O(40)](2)·5C(5)H(11)NO, there are two independent α-Keggin-type [PMo(12)O(40)](3-) polyoxidoanions, which show characteristic features with respect to bond lengths and angles. One of the [CH(3)CH(2)C(=OH)N(CH(3))(2)](+) cations is hydrogen bonded to the neighboring polyoxidoanion through a C=O-H⋯O(bridge) hydrogen bond. The organ...

A series of 8 new complexes of titanium and zirconium with diamido ligands bearing an ethylene and propylene bridge between the two amido groups were synthesized and tested for ethylene polymerization. Titanium complexes bearing an ethylene bridge between the two amido groups showed higher activities than the derivatives with a propylene bridge. In the case of the zirconium complexes, the p...

Abstract To explore the effect of canyon topography on seismic response railway irregular bridge–track system that crosses a V-shaped canyon, ground motions horizontal site and were simulated through theoretical analysis with 12 earthquake records selected from Pacific Earthquake Engineering Research Center (PEER) Strong Ground Motion Database matching condition bridge. Nonlinear analyses an ex...

Enhanced p l a in TJ$ macros and a bidding environment for typesetting bridge card distributions and bidding sequences are given as a follow-up to the IPW macros given in [12]. Moreover, macros for annotated printing of the course of the play are provided. Examples of use are included.
