Appropriate design of collaborative learning activities for students using 1:1 handheld devices can lead to peer scaffolding, building up students‟ collaborative skills. Building on such prior studies in mCSCL (mobile Computer Supported Collaborative Learning), we derived Chinese-PP, a novel design of in-class mobile synchronous collaborative learning game on constructions of Chinese characters...

The results of an ongoing FEM parametric study are presented regarding the dependence of the resulting piled raft behavior under lateral load and combination of loads on pile diameter, pile length, arrangement of piles and raft thickness. Taguchi method with Analysis of Variance (ANOVA) was employed to calculate the contribution ratio of these factors on the lateral displacement of piled raft. ...

in this study the effects of plant growth regulators including; ga3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (perlette and yaghuti). at the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and l/d ratio, flesh firmness, fresh weight, ta, ph, tss and fruit color were ...

the focus of this paper is to evaluate the influence of mechanical characteristics of the implant on primary stability in different bone types, based on resonance frequency analysis (rfa).a number of 60 nobel biocare replace select tiunit tapered implants of two different lengths (10 mm and 13 mm) and three different widths as 3.4 mm (narrow platform (np)), 4.3 mm (regular platform (rp)) and 5 ...

this study was performed in order to evaluate the effects of application of super absorbent on the yield and water use efficiency of cucumber under deficit irrigation conditions in greenhouse. plants cultivated in plastic pots and irrigation emitter with four liters per hour discharge was performed. three levels of irrigation water height (10, 8.3 and 6.2 mm day-1) were used as the main factor ...

the autotetraploidy was achieved in basil using tip meristem treatment of seedlings with various concentrations of colchicine solution (0, 0.05, 0.1, 0.2, 0.5 and 0.75% (w/v) ph = 6). a significant increase in the essential oil content was observed in tetraploids as they carry the potential of productivity of 69 % more oil over the diploids. a field experiment was conducted to investigate the e...

• In 1888, a histological study Avas made of blood vessels in dog mesentery by Mall. Several decades later, the data were used by Schleier to discuss the effects of branching of an arterial tree on the velocity and pressure of blood. Mall's data were again used by Green, in 1944, to compute the approximate dimensions, numbers, lengths, and total crosssectional area of component parts of the cir...

abstract this reasearch was conducted to study the phenotypic diversity of thymus kotschyanus populations. seeds were collected from natural inhabitats (guilan, mazandaran, west azarbaijan, semnan and qazvin) and planted in qom reasearch station in 2007. a number of some such different morphological and phenological traits of the plants as plant,s height, leaf length, leaf width, oil content, i...

Introduction: The human anthropometric characteristics are surveyed in anthropology. Anthropology is used in archeology, rehabilitation and legal medicine. The purpose of this study was to determine femur which has a special place in the science of anthropometry. Methods: To measure the femur, both direct and indirect methods was used. The direct method of measuring the 113 femur in dissection...
