this study was conducted to investigate the impact of portfolio assessment as a process-oriented assessment mechanism on iranian efl students’ english writing and its subskills of focus, elaboration, organization, conventions, and vocabulary. out of ninety juniors majoring in english literature and translation at the university of isfahan, sixty one of them who were at the same level of writing...
this ethnographic case study research was carried out in a private school setting in the context of iran. the research tried to explore the analysis and identity construction of a group of learners and teachers along with the content analysis of books on the basis of four types of commodified, political, national and narrative identities. how english language learners and teachers in an informa...
BACKGROUND/AIMS Measuring and predicting Alzheimer's disease (AD) progression is important in order to adjust treatment and allocate care resources. We aimed to identify a combination of subtests from the Consortium to Establish a Registry for Alzheimer's Disease Neuropsychological Battery (CERAD-NB) that best correlated with AD progression in follow-up as well as to predict AD progression. M...
Clock recovery circuits which extract the clock signal from random NRZ data are very important to the multigigabit-per-second integrated receivers. Regarding the factors of flexibility and cost of implementation, phase-locked loops are standard approaches to CRCs. In a PLL, the phase detector is a key component which determines several significant properties of the PLL. The goal of this project...
As data communication rates climb toward ten Gbls, clock recovery and synchronization become more dificult, if not impossible, using conventional electronic circuits. We present in this article experimental results of a high speed clock and carrier recovery using a novel device called the photonic oscillator that we recently developed in our laboratory. T h i s device is capable of recovering c...
Communications service providers (CSPs) are being pushed to the lower end of the value chain by standalone, over-the-top (OTT) players and Internet of Things (IoT)—which are able to establish direct customer touch points. However, there is a proven methodology for CSPs to transform and migrate their data assets into the digital landscape to meet their business objectives. Business Imperatives f...
copper extraction from heap 3 low grade ore at sarchechmeh is limited due to its mixed composition (copper oxide and sulphide minerals). changing this heap to a bioheap could improve the copper recovery.
A burst-mode clock recovery circuit with a novel dual-mode structure is presented. It utilizes two gated-oscillators to align recovered clock edges to data. It can operate in double data-rate mode in which both rising and falling edges of recovered clock are used. To enable this, gated-oscillator reset-phase control scheme is introduced to switch the starting phase of gated-oscillator dynamical...
Background: Promoter hyper-methylation of tumor suppressor genes is a common event that occurs in cancer. As methylation is a reversible modification, agents capable of reversing an abnormal methylation status should help to combat cancer. 5-Aza-CdR is a DNA methyl-transferase inhibitor. The present study aimed to evaluate the effect of 5-Aza-CdR on the proliferation of human pancreatic cancer ...
abstract: country’s fiber optic network, as one of the most important communication infrastructures, is of high importance; therefore, ensuring security of the network and its data is essential. no remarkable research has been done on assessing security of the country’s fiber optic network. besides, according to an official statistics released by ertebatat zirsakht company, unwanted disconnec...
