the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
abstract ion selective electrodes (ises) are electrochemical sensors that respond selectivity to the activity of ionic species. an ion-selective electrode is an electrochemical device that uses a thin selective membrane or film as the recognition element, and is an electrochemical half-cell equivalent to other half-cells of the zeroth (inert metal in a redox electrolyte). in common methods o...
INTRODUCTION The aim of this systematic review was to examine the effects of a lingual arch on mandibular arch dimensions when it is used as a space maintainer. METHODS PubMed, Medline, Lilacs, Cochrane Central, and Cochrane Database of Systematic Reviews were surveyed for articles published between January 1980 and January 2009. Inclusion criteria were human subjects, prospective or retrospe...
Aim of this paper is to search and find ways and methods of constructivism teaching and learning ideas inteaching the architectural design studio. The objective is to extract all the positive things constructivism has to offer the architectural design studio for efficient teaching and effective learning. Although there are similarities in the curricula of training architects all over the world,...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
statement of the problem: the stability of orthodontic treatment depends on preserving the patient’s pretreatment arch form and arch size during and after treatment. purpose: this investigation was aimed to study the size and shape of iranian mandibular dental arch and evaluate the correlation of their average dental arch with commercially available preformed rectangular nickel-titanium arch wi...
abstract part one: the electrode oxidation potentials of a series of eighteen n-hydroxy compounds in aqueous solution were calculated based on a proper thermodynamic cycle. the dft method at the level of b3lyp-6-31g(d,p) was used to calculate the gas-phase free energy differences ,and the polarizable continuum model (pcm) was applied to describe the solvent and its interaction with n-hydroxy ...
Purpose: Several variations of aortic arch have been reported yet. In present study another variation of aortic arch was reported. Right subclavian artery arises from posterior surface of the distal end of the aortic arch. Case Report: we present a variation of an aorticarch in which right subclavian artery arisesfrom posterior surface of the distal end of the aortic arch and passing behind eso...
The term "bovine arch" is widely used to describe a common anatomic variant of the human aortic arch branching. This so-called bovine aortic arch has no resemblance to the bovine aortic arch. We describe the most common human aortic arch branching patterns and compare these with the bovine aortic arch.
