Puffs are local Ca(2+) signals that arise by Ca(2+) liberation from the endoplasmic reticulum through concerted opening of tightly clustered inositol trisphosphate receptor/channels (IP(3)R). They serve both local signaling functions and trigger global Ca(2+) waves. The numbers of functional IP(3)R within clusters differ appreciably between different puff sites, and we investigated how the prob...
There are various ways to control a computer, but today the mouse function, to move a cursor and to perform a click function, is essential. For motion-disabled persons, especially persons with high spinal cord injuries, special aids are needed to perform these interactions. In this study, an alternative way to perform a click function has been investigated, the sip-and-puff function. The purpos...
the purpose of this study was to examine the status of supervision on departments’ heads at ferdowsi university of mashhad (fum) and realize some applied themes to provide a fit model for supervising departments’ heads in fum. the method was case study under a research category aimed for applied one. using purposive sampling, interviews were conducted with top fum managers, head departments, an...
A set of parameters is introduced to characterize the dispersion of puff releases based on the measured dosage. These parameters are the dosage, peak concentration, arrival time, peak time, leaving time, ascent time, descent time and duration. Dimensionless numbers for the scaling of the parameters are derived from dimensional analysis. The dimensionless numbers are tested and confirmed based o...
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
Generalized convulsive seizures are frightening to observe and often result in EMS calls. Seizures may be the symptom of a serious underlying medical or neurologic condition or may refl ect recurrent seizures, alcohol-related seizures, or poorly controlled epilepsy. It is estimated that between 1% and 2% of emergency department (ED) visits are for seizure-related complaints, with the majority o...
this study was an attempt to investigate the effect of teaching meta cognitive strategies on iranian intermediate efl students speaking proficiency. in this study the researcher has employed metacognitive strategies taken from brown (2000) to teach speaking strategies to number of participants. the participants were intermediate students of shokouh language institute; they were divided into an ...
a significant problem in multicarrier communication systems is the necessity to reduce the value of papr (peak-to-average power ratio) of transmitting signal. in this thesis we study the effect of the system parameters such as coding and modulation types on papr and ultimate ber in a mc-cdma system. in this study we consider fading channel as well as the nonlinearity of transmitter’s amplifier ...
the purpose of this study was to examine the comparative effect of story retelling and role playing on efl learners’ vocabulary learning and reading comprehension. to carry out the purpose of the study 90 female learners of tabarestan language school located in noshahr were non-randomly selected. they took pet test and among these 90 participants 62 students were selected as homogenous learners...
