oxidative addition reactions of 1,4-diiodo-butane and 1,3-diiodo-propane with [ptme2(ph2phen)]; in which ph2phen=4,7-diphenyl-1,10-phenanthroline, were studied in different solvents such as acetone and benzene.oxidative addition reaction of [pt me2(ph2phen)] with i(ch2)4i and i(ch2)3i produced the [pt me2i(ch2)4(ph2phen)i] (1a) and [pt me2i(ch2)3(ph2phen)i] (1b).all the platinum (iv) products w...
the application of a comprehensive model of communicative language ability (cla) to language teaching and testing has always been an imperative in l2 education since hymess proposal of communicative competence in the 1970s. recent l2 research has clearly underscored the importance of sufficient pragmatics representation as an essential component of cla in pedagogical and testing practices in l2...
Provided that the data show that a compound is safe, it is the primary efficacy analysis that determines whether the compound is approved. The secondary analyses support, clarify and confirm, but only one prospectively planned efficacy analysis can be primary in support of an effectiveness claim for a given trial. Why should this be so? And how can we design the trial and set up the primary eff...
from its emergence till present time marxist principles has undergone great changes since their promulgation by marx. many theorists and thinkers set at rectifying marxist tenets and introducing those of their own while others advocated its main concepts and attempted at improving them. among marxist philosophers who had an intensive study of marxs ideology, is louis althusser whose reflections...
This study investigated the role of women’s economic empowerment on fertility behaviour using Ogbia Local Government Area in Bayelsa State as a case study. The study sought to know how different women’s economic empowerment indicators can affect different fertility behaviour. The Quality-Quantity theory and Feminist patriarchal theory served as the theoretical framework for the study. The sampl...
هدف از انجام این پایان نامه برسی تاثیر خود آزمایی با چک لیست بر روی مهارت نوشتاری دانش آموزان با دانش زبانی متوسط میباشد.طبق تعریف alderson (2000) خودآزمایی به معنی قبول مسئولیت ، داشتن کنترل و قضاوت در مورد همه ی جنبه های یاد گیری زبان انگلیسی میباشد. برای رسیدن به این هدف گروهی از دانش آموزان موسسه سخن در سطح pre-intermediate انتخاب شده اند تا در این تحقیق شرکت کنند. در تمام طول ترم خود آزمای...
This study assessed stress and their attendant coping mechanisms employed by the senior members in the University of Cape Coast. The descriptive survey research design was employed in conducting the study. In all, 214 senior members were sampled through the use of the convenient sampling procedure. Questionnaires were used to solicit for the requisite data for the study. Descriptive statistics ...
this thesis is presented 10 ghz voltage controlled ring oscillator for high speed application. the voltage controlled ring oscillator was designed and fabricated in 0.13یm cmos technology. the oscillator is 7-stages ring oscillator with one inverter replaced by nand-gate for shutting down in the ring oscillator during idle mode. tri-state inverter was used to control of 126 bit vector in ri...
the space now known as complete erdos space ec was introduced by paul erdos in 1940 as the closed subspace of the hilbert space ?2 consisting of all vectors such that every coordinate is in the convergent sequence {0} ? { 1 n : n ? n}. in a solution to a problem posed by lex g. oversteegen we present simple and useful topological characterizations of ec. as an application we determine the ...
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 ...
