This study develops mathematical models for obtaining optimum flexural strengths of normal laterised(NLC) and high strength laterised concretes (HSLC). The can be expressly used to evaluate the indirect tensile both types without going through traditional methods mix design. Optimum mixing ratios predicted are also supplied by models. three point load method was adopted testing strengths. Later...
building on previous studies on the effectiveness of different types of written corrective feedback, the present study aimed at investigating whether direct focused corrective feedback and direct unfocused corrective feedback produced any differential effects on the accurate use of english articles by efl learners across two different proficiency levels (low and high). in current study, the par...
Background & Aims: The purpose of this study was investigating the relationship of sensation seeking and self-regulation in delinquent and normal adolescent boys. Methods: In this descriptive-correlation study, 80 delinquent adolescent boys who were habitant in Mashhad Training and Improvement Association, Mashhad, Iran, were selected via random simple sampling method; and 80 normal male studen...
nowadays, the development of anti cancer drugs is an important subject in pharmacology. bisphosphonates (b.p) are a great choice for design and production of the types of drugs which not only could perform as anti cancer agents but also could inhibit the function of acetyl cholinesterase (ache). ache hydrolyzes the acetylcholine (which is a neurotransmitter in nervous system) using the oh in i...
The construction methods currently adopted for multi-story concrete buildings resorts the strategy to cast columns and slabs with high normal compressive strength, respectively. intersection region affects load transfer performance of columns, causing expressive confinement stress in interior columns. However, when is only provided by two sides, as corner it not enough increase lateral stress. ...
background and aims. effect of surface treatments on repair bond strength of aged composite resins might be different due to their dissimilar fillers. the aim was to evaluate the effect of different surface treatments on repair micro-shear bond strength (µsbs) of silica- (spectrum tph) and zirconia-filled (filtek z250) composite resins. materials and methods. twenty-seven composite resin blocks...
Self-control and cognition are among the factors involved in the tendency toward delinquency. The aim of this study was to compare self-control and metacognition components in normal minors and juvenile delinquents at correction and rehabilitation centers. This was a causal-comparative descriptive study. The statistical sample included 70 juvenile delinquents (55 boys and 15 girls), selected...
background: as the use of different irrigants to eliminate residual debris and smear layer in the field of endodontic is unavoidable, by considering the effect of irrigants on the bond strength of resin composite restorations, this study was designed to evaluate the effect of a mixture of a tetracycline isomer, an acid, and a detergent (mtad) on the shear bond strength of two self-etch adhesive...
The intent of this paper is to study the structural behavior voided normal and high strength reinforced concrete two-way slabs. Voided slab a hollow core which has an advantage reducing self-weight by mass within center zone section. experimental program included testing twelve simply supported specimens with dimensions (1100 x 1100 100) mm, they were subjected vertical four patch loads. Many p...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
