By following closely Weinberg's soft theorem, which captures the $1/\omega$ pole contribution to amplitude for graviton emissions ($\omega<\Lambda$) on top of an arbitrary background hard process, we calculate expectation value graviton's angular momentum operator collisions dressed with radiation. We find that result becomes independent cutoff $\Lambda$ frequency, effectively localizing at $\o...
study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
the present study was concerned with exploring the frequency and linguistic focus of corrective feedback types given by novice and experienced female teachers working with young learners and compared it with those of elementary classes for adults. moreover, it aimed at measuring learners’ acknowledgement of teachers’ corrective feedback in the form of uptake in relation to linguistic coverage o...
abstract pragmatics is the study of communicative action in its sociocultural context. communicative action includes not only using speech acts (such as apologizing, complaining, complimenting, and requesting), but also engaging in different types of discourse and participating in speech events of varying length and complexity. the present study aimed to investigate the assessment of pragm...
abstract: the present study is an attempt to find out cultural exophoric references in iranian high-school elt textbooks and touch stone series to compare the frequency of occurrence of such references in these books. the purpose is to find out which of the series of the books under investigation impose a greater referential burden on efl learners as far as their reading comprehension of the ...
Recent studies state the importance of conceptual modeling in simulation life cycles. Proper development of a conceptual model is critical for expressing the context, elements, relationships, limitations and purpose of the simulation study. Surprisingly there are many simulation projects that have no explicit conceptual model, a poorly or only partially developed conceptual model, or incomplete...
A CTF3 drive beam injector for the nominal stage is proposed, which includes thermionic DC gun, three SubHarmonic Bunchers (SHBs), one prebuncher, one 6-cell travelling wave buncher and two accelerating structures. Its beam dynamics is simulated by PARMELA. It is shown that all important parameters, e.g. satellite charge, bunch length and normalized transverse emittance can be met with the desi...
The paper deals with the problem of angular vibration measurements in time history of rotation angle, angular velocity or angular acceleration. The source of information about angular vibrations is an encoder producing an impulse signal. It is supposed that the impulse frequency is changed proportionally to the rotational frequency. A time record of an impulse signal is transformed to an analyt...
the present study was an attempt to conduct a contrastive analysis between general english (ge) and english for specific purposes (esp) texts in terms of cohesion and cohesive devices. to this end, thirty texts from different esp and ge textbooks were randomly selected. then they were analyzed manually to find the frequency of cohesive devices. cohesive devices include reference, substitution, ...
