We propose a class of decisive collective choice rules that rely on linear ordering to partition the majority relation into two acyclic relations. The first these relations is used pare down set feasible alternatives shortlist while second make final from shortlist. Rules in this are characterized by four properties: classical rationality requirements (Sen's Expansion Consistency and Manzini Ma...

The Chadegan metamorphic complex is a WNW-ESE- trending antiformal structure located in Sanandaj-Sirjan structural zone, Iran.The inner core of the structure is made of orthogneiss, containing eclogitic lenses. Schists and marbles lie structurally above theorthogneiss and crop out in the external limbs of the antiformal dome. Two main deformational episodes have been documented in theschists an...

We introduce a new concept in column generation for handling complex large scale optimization problems, called two-stage column generation, where columns for the compact and extensive formulation are simultaneously generated. The new framework is specifically conceived for tackling complex problems that cannot be efficiently solved by standard column generation and exploits the relationship bet...

Since the advent of osseointegration approximately 20 years ago, there has been a great deal of scientific data developed on two-stage integrated implant systems. Although these implants were originally designed primarily for fixed prostheses in the mandibular arch, they have been used in partially dentate patients, in patients needing overdentures, and in single-tooth restorations. In addition...

the aim of this study is to investigate the role and structure of motivation in learning a foreign language in order to introduce the model ofinformation processing as a new approach and scale to evaluate themotivation of foreign languages.for this purpose,two hundred and fifty participant employees ofthe iranian oil terminals company enrolled in the english language training courses were selec...

the structure and histogenesis of the stigma of datura stramonium was investigated by light and scanning electron microscopy to determine the developmental origin of the transmitting tissue and “wet stigma”. four developmental stages were defined on the basis of bud length. stage one, the histogenesis stage, was comprised of buds 2-15 mm in length. stage two, signified by the growth and develop...
