there are now several tests available that can assess fetal status. a series of 164 cases of high risk pregnancies were studied in order to assess predictive value of a nonstress test. the majority (36%) of patients complained about postdate pregnancy. a nonreactive test was identified in 24 of the patients (14.6%). fetal distress, low apgar score in 1 and 10 minutes after birth and mean of apg...
within the components of communicative competence, a special emphasis is put on the “rules of politeness,” specifically the politeness strategies (brown and levinson, 1978) that speakers deploy when performing the request speech act. this is because the degree of imposition that making a request places upon one’s interlocutor(s) has been seen to be influenced by several factors among which, as ...
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
A bunching system is proposed for the initial stage of CTF3 which consists of one (two) 3 GHz prebuncher(s) and one 3GHz travelling wave (TW) buncher with variable phase and group velocities. The electron beam is emitted from a 140 KV DC gun. Since the average macropulse beam current (3.5 A) at the exit of the TW buncher is rather high, inside the TW buncher one has to take the beam loading eff...
At Brookhaven National Laboratory there is an R&D program to design an Electron Beam Ion Source (EBIS) for use in a compact ion injector to be developed for the relativistic heavy ion collider (RHIC). The BNL effort is directed at developing an EBIS with intensities of 3 x 10 particles/pulse of ions such as Au and U, and requires an electron beam on the order of 10A. The construction of a test ...
The realisation of a 7 tesla/25 kA test facility for measuring the critical current density and the quench propagation velocity of high-current superconductors has already been reported [11. The test volume in this set-up is torus-shaped having a diameter of 0.2 m and a cross-section of 5 cm2. The test facility has been equipped with a set of AC coils and pick-up coils in order to perform AC lo...
