Floodwater spreading (FWS) has an important role in floodwater control, groundwater recharge, restoration and enhancement of vegetation and desertification control. Since the flood causes the transporting of soil particles including organic materials, the floodwater spreading project can be a suitable place to sequestration of organic carbon in sediment yielded by flood. The knowledge of soil o...
Objective: Zirconia cores have limited light transmittance and data are scarce on light transmission through zirconia cores with and without the veneering ceramic. Methods: In this in vitro study, Disc-shaped specimens (11.5 mm in diameter and 0.4 (0.05) mm in thickness) were fabricated of three types of zirconia namely Mamut, Heany and ZirkonZahn (n=5). A disc-shaped specimen (11.5 mm in d...
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
the purpose of the present study was to investigate the effect of task-based instruction of vocabulary on the receptive and oral productive acquisition of english vocabulary and compare the results with those obtained from the traditional method. the method and procedure applied in this study was as follows: after the implementation of opt, a group of sixty female students were chosen. the stu...
The three-dimensional organization of the smooth endoplasmic reticulum (SER) in Purkinje cell dendrites in the chick cerebellum was investigated to assess the connectivity between its various components. Three-dimensional reconstructions of the SER within portions of Purkinje cell dendrites were performed from serial sections through the cerebellar molecular layer. In addition, semithick and th...
Abstract Traditional railway power supply systems impose substantial power quality problems (PQ) on the utility network, such as unbalance, harmonics and a large amount of reactive power. This paper proposes a topology based on three-phase to single-phase modular multilevel converters (MMC) to obviate these problems. The MMC based traction substations (TSS) are connected directly to the utili...
Most popular models of narratives and narrative analyses have been drawn on native stories, yet EFL learners’ narratives have not received due narrative analysis. The present study then aims at scrutinizing the structure of personal English stories as told by EFL learners. To this aim, three hundred narratives were collected through classroom discussions and interviews. Qualitative analysis met...
We present some basic properties of two general graphical techniques for constructing views of high-dimensional objects, projection and section. Projections can easily display aspects of structure that are only of low dimension, while sections, i.e., intersections of subspaces with a highdimensional object, can easily display structure of only low codimension (and hence often high dimension). H...
