Optimization of pretreatment and various gas-solid interaction conditions is necessary for effective carbonation recycled coarse aggregates derived from concrete wastes (RCA). This study demonstrated the use linear weighted sum method to simultaneously optimize test conditions. The optimization produced simplified, eco-friendly pretreatments drastically reduced duration RCA 72 h 3 weeks in prev...
abstract in a protocol analysis of second language writing from 20 adult english as a foreign language (efl) iranian students, this research observed how language-switching (l-s), i.e., first language use in l2 writing, was affected by l2 proficiency. switching interactively between first (l1) and second (l2) languages has been recognized as one of the salient characteristics of l2 writing....
abstract this research has been carried out with the purpose of investigating the conditions and related elements of the employment of the educational sciences graduates of hamedan province universities in 1382-1387 academic years. it has been a descriptive research of a correlation kind, and the population number has been 1180 grduates of payam- e noor universites in asad – abaad, kaboudaraha...
the present study set out (a) to examine the categories of pedagogical knowledge related to the act of teaching of novice and experienced teachers as gleaned from their verbal report of what they were thinking about while teaching and (b) to compare the categories of pedagogical knowledge of novice and experienced teachers. the aim of comparing these two groups of teachers was to see whether di...
In-Flight ElectroSpraying (IFES) is a novel approach to generate electrically charged micrometer-sized and/or nanometer-sized progeny drops in a controlled manner. This is accomplished in ight, beginning with millimeter-sized parent drops. The breakup of charged drops that is exploited in IFES also occurs (sometimes unwantedly) in conventional electrospraying, electrospinning, and electrospray ...
for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...
The within-field spatial distribution of beneficial arthropods was assessed using two-dimensional grids of pitfall traps and suction sampling across two winter wheat fields of 4 and 16 ha, before and after an application of dimethoate. An unsprayed 6 m wide buffer zone was left around half the edge of the larger field. Arthropod numbers fluctuated to varying extents prior to spraying. Two speci...
The differential quadrature method (DQM) is one of the most elegant and useful approximate methods for solving initial and/or boundary value problems. It is easy to use and also straightforward to implement. However, the conventional DQM is well-known to have some difficulty in implementing multiple initial and/or boundary conditions at a given discrete point. To overcome this difficulty, this ...
investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
