Dimensionless coefficient () in convergence confinement method shows the relaxation of stress in the wall of the tunnel at different excavation movements. This factor is considered a constant number in previous studies and tunnel geometric characteristics (such as depth, cross-section shape, radius, soil material, etc.) are not included in its determination; however, ignoring these effects can...

Exclamative constructions form a variegated class, both within and across languages. This article presents a typological survey of the coding of exclamations. This survey will proceed in the following fashion. First, we will explore the conceptual basis of the category exclamation, and in particular the category of degree exclamations (section 2). Second, we will examine the formal, semantic an...

dalichai formation at the rey-abad section (northeast shahroud) along the principal road of the mayamey-jajarm has a thickness of 166 meters .in this section, middle to upper jurassic carbonate rocks are well exposed and is typically composed of massive to medium-bedded limestones with thin shale interbeds. in the studied area and most places of this region, the lower boundary of dalichai forma...

moment-resisting frames have extensive usage in earthquake-prone areas and high ability in energy dissipation.after the earthquake in northridge 1994,kobe 1995 fixed connections of steel structures have shown poor performance and generally they were caught brittle fracture of beam flange weld to the column.in order to remedy to avoid similar situations in future earthquakes,researchers introduc...

This paper is to serve as an introduction to the study of symmetric spaces, with the goal of describing Hermitian symmetric spaces of noncompact type. There are three basic types of symmetric space: compact, noncompact, and Euclidean, defined in terms of properties of g, the Lie algebra of its group of isometries. It turns out that a simply connected symmetric space can be described completely ...

in order to determine the dalichai formation paleoecology (middle jurassic), with measured thicknesses of 255 m at bar section, nw neyshabour, 28 samples systematically were collected. based on 112 palynological slides studies, 29 species of spore and pollen, which belong to 21 genera, have been identified. in addition to spores and pollens, dinoflagellate and fungus bodies form the palynomorph...

background: dental wastes are one of the environmental issues due to toxic and pathogenic agents such as pathological wastes, pharmaceutical and chemical etc have particular sensitivity. the aim of this study was to determine the dental waste management and related factors in the city of ilam. methods: in this cross-sectional study, the studied community was all the sixteen dental clinics in il...

This paper is a sequel to the paper [7] in which generalized Cartan type S Lie algebras tzS(A, T, φ) over a field F of characteristic 0 were studied. We have tried to make this paper independent of other papers. So in Section 2, we give a description of relevant Lie algebras and some basic facts which will be used in this paper. In Section 3 we introduce a class of Lie algebras which are subalg...

OBJECTIVE Frozen section is an accurate diagnostic tool with some unavoidable pitfalls in gynecologic tumors. We aimed to evaluate the diagnostic value of frozen section, and to detect the factors causing erroneous diagnosis in ovarian tumors. MATERIAL AND METHOD Frozen section and paraffin section reports of 282 patients with ovarian neoplasms diagnosed between July 2006 and January 2013 in ...
