subsea structures such as manifolds, line pipes and flow lines are important investments. also because of the sensitivity of environmental issues, corrosion of these structures is of vital importance. subsea corrosion management is different from on-shore and shallow water off-shore corrosion management in mainly three factors: materials, corrosion management practice and cathodic protection. t...

objectives: language development is often very slower in hearing impaired children compared with their normal peers. hearing impairment during childhood affects all aspects of speech production and language acquisition. it seems that hearing impaired people suffer from language and speech impairments such as production of complex linguistic structures. the purpose of this study is to determine ...

unlike the languages we know, some of the arabic sentences form without any verbs. arab grammarians call these sentences, which contain a subject and a predicate without any linking verbs, nominal sentences. examining theses sentences indicates that their predicate is composed of one of the following words or structures: 1. noun, 2. prepositional phrase, 3. an adverb of time or place, 4. a nomi...

an ab initio and density functional theory (dft) study about conformational analysis of tripeptide model hco−gly−l−ile−gly−nh2 is presented. the tripeptide was scanned about initial, central, and final residues, separately while for every scanning procedure the two other residues had been kept in the β conformation and side chain (sc) dihedral angles were maintained on the gauche− (g‾) state (χ...

copper oxide nanostructures have been successfully synthesized via one-step solid-state thermolysis of two metal-organic frameworks, [cu3(btc)2] (1) and [cu(tpa).(dmf)] (2), (btc = benzene-1,3,5-tricarboxylate, tpa = therephtalic acid = 1,4-benzendicarboxylic acid and dmf = dimethyl formamide) under air atmosphere at 400,  500, and 600°c. it has also been found that the reaction temperature pla...

a case of an interesting previously unreported mixed adnexal tumor of the scalp of a 38 year old man is presented, which was composed of randomly dispersed areas of trichofolliculoma, trichoepithelioma, and pilomatricoma concomitantly. while these lesions are classified under adnexal tumors with differentiation towards hair follicle structures, controversy is present concerning the exact origin...

this study investigated the effectiveness of individual and collaborative outputbasedfocus-on-form instructional tasks on the acquisition of english inversionstructures by efl learners. moreover, it explored the developmental trend oflearners’ inversion acquisition. to this end, 60 homogeneous efl learners wereassigned to individual and collaborative output groups. they were exposed to textsenc...

for the analysis of structures, the first step consists of configuration processing followed by data generation. this step is the most time consuming part of the analysis for large-scale structures. in this paper new graph products called triangular and circular graph products are developed for the formation of the space structures. the graph products are extensively used in graph theory and co...

nonlinear static procedure (nsp) is a common technique to predict seismic demands on various building structures by subjecting a monotonically increasing horizontal loading (pushover) to the structure. therefore, the pushover analysis is an important part of each nsp. accordingly, the current paper aims at investigating the efficiencyof various algorithms of lateral load patterns applied to the...
