sciences exist to demonstrate the fundamental order underlying nature. chaos/complexity theory is a novel and amazing field of scientific inquiry. notions of our everyday experiences are somehow in connection to the laws of nature through chaos/complexity theory’s concerns with the relationships between simplicity and complexity, between orderliness and randomness (retrieved from http://www.inc...
the purpose of this two-phase, sequential mixed methods study was to find out whether there were any decencies between male and female ma students’ theses regarding the common features of academic writing such as syntactic complexity, means of integrating cited information, and organizing arguments. i chose 10 male written theses and 15 female written theses in tefl and linguistics. in the firs...
هدف اصلی این تحقیق بررسی تاثیر افزایش میزان پیچیدگی تکالیف مکالمه محور بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 15 الی 18 سال درسطح pre-intermediate از طریق petو vhs تست به عنوان شرکت کنندگان در تحقیق انتخاب شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی دو تکلیف ساده و پیچیده را طی 2 جلسه انجام...
ارزیابی اثر داروی انروفلوکساسین بر فرایند آنژیوژنز با استفاده از مدل غشاء کوریوآلانتوئیک جنین ماکیان
چکیده به منظور ارزیابی تأثیر داروی انروفلوکساسین بر روی فرایند آنژیوژنز، تخم مرغ های نژاد راس (میانگین وزن 4±55 گرم) انکوبه شدند. در روز چهارم انکوباسیون، یک پنجره ی 5/1×1 سانتی متری در محور طولی ایجاد شد و تخم مرغ ها به دو گروه تقسیم شدند (7 تخم مرغ در هر گروه). در روز 7، انروفلوکساسین (mg/ky egg weight 10) در گروه درمان، روی پرده کوریوآلانتوئیک تلقیح شد و گروه کنترل pbs دریافت کردند. سه روز ...
This study examined the effects of task complexity on written narrative production under different task complexity conditions by EFL learners at different proficiency levels. Task complexity was manipulated along Robinson’s (2001b) proposed task complexity dimension of Here-and-Now (simple) vs. There-and-Then (complex) in. Accordingly, three specific measures of the written narratives were targ...
the aim of this study is to show that the measures derived from electrocardiogram (ecg) signals many a time perform better than the same measures obtained from heart rate (hr) signals. a comparison was made to investigate how far the nonlinear symbolic dynamics approach helps to characterize the nonlinear properties of ecg signals and hr signals, and thereby discriminate between normal and cong...
due to the particular importance of projects in human life and in organizations, proper project management has been always regarded highly by researchers and practitioners. recent advances in technology and fundamental changes in most scientific areas have affected projects and made their nature and environmental circumstances much more complex than in the past. fortunately, in recent years, ma...
the notion of sustainable development has rapidly gained considerable attention since the lastdecades of the twentieth century. it has become a locus for global paradigm shift on environment and development issues particularly after rio conference in 1992. the comparative analysis of agenda 21 and major un documents, mdg, and rio+20 as well as some major sources are made to provide a context fo...
Complexity is one of the most important issues of any production planning. The increase in complexity of production planning can cause inconsistency between a production plan and an actual outcome. The complexity generally can be divided in two categories, the static complexity and the dynamic complexity, which can be computed using the ant ropy formula. The formula considers the probability of...
slope stability analysis is a geotechnical engineering problem characterized by many sources ofuncertainty. in slope stability computations, some of these sources are encountered, such as geologicaldetails missed in the exploration program, estimation of soil properties that are difficult to quantifyand many other relevant factors. therefore, accurate reproduction of the spatial variability in ...
