abstract sensitive and precise voltammetric methods for the determination of trace amounts of furaldehydes, mainly as furfural (f) and 5-hydroxymethyl-2-furaldehyde (hmf), in waste waters and other matrices is described. determination of total furaldehyde at < ?g g-1 levels in alkaline buffered aqueous media was individually investigated. by the use of ordinary swv and adsorptive square wave ...
in the area of vocabulary teaching and learning although much research has been done, only some of it has led to effective techniques of vocabulary teaching and many language learners still have problem learning vocabulary. the urge behind this study was to investigate three methods of teaching words. the first one was teaching words in context based on a traditional method of teaching that is,...
منظور از { r{an توپولوژی حلقه ای روی حلقه ی r است که در بین همه ی توپولوژی های حلقه ای روی r که در آن ها t-دنباله ی {an} به صفر همگرا است ماکزیمم باشد در این پایان نامه ابتدا با کمک پالایه ها قضیه ی مهمی راجع به کامل بودن { r{an بیان می کنیم و...
فرض کنیم c یک زیرمجموعه ی محدب، بسته وناتهی در یک فضای باناخ e و {ُsn} خانواده ای از نگاشت های نامنبسط از c به توی c باشد به طوری که مجموعه نقاط ثابت مشترک خانواده {sn} ناتهی است. دنباله {xn} در c را به ازای هر n ، باx=1x در c xn+1=an f(xn)+(1-an)snxn تعریف می کنیم که در آن ( an}?(0,1 } وf یک انقباض از c به c است. در این پایان نامه شرایطی بر{ an} و {sn} تعیین می کنیم که تحت ان شرایط {xn} همگ...
depth estimation of the top of the bedrock in the sedimentary basins is the main goal in geomagnetic explorations. the depth estimation of this kind of anomalies can be done using different methods, in the cases where the bedrock is magnetized. in this article, we use the standard euler deconvolution method and its results to interpret the magnetic data from the reshm region in semnan province ...
Clinical observations with AN-1792 using tissue amyloid plaque immunoreactivity (TAPIR) analyses established for the first time evidence in humans that antibodies against beta-amyloid-related epitopes are capable of slowing progression in Alzheimer's disease. Antibodies derived upon TAPIR assay selection may specifically target the pathologic neoepitopes of aggregated A beta species present in ...
In this document, we define the NADA security architecture based on refined use case scenarios, a derived high level model and security analysis. For the architecure design and verification we are applying the well known STRIDE model.
Spinning dust appears to be the best explanation for the anomalous emission that has been observed at ∼ 10 − 60 GHz. One of the best examples of spinning dust comes from a HII region in the Perseus molecular cloud. Observations of other HII regions also show tentative evidence for excess emission at frequencies ∼ 30 GHz, although at lower emissivity levels. A new detection of excess emission at...
In this paper, we introduce the concept of 3-D radar signatures in a slow time-range-Doppler, fast timerange-Doppler and frequency-range-Doppler. Then, we describe how to utilize 3-D time or frequency-rangeDoppler signatures to extract information for detecting, relocating and re-focusing moving targets. Finally, we use AN/APY-6 X-band radar data for the demonstration of ground moving target de...
In a multi-study naturalistic quasi-experiment involving 269 students in a semester-long introductory philosophy course, we investigated the effect of teaching argument diagramming (AD) on students’ scores on argument analysis tasks. An argument diagram is a visual representation of the content and structure of an argument. In each study, all of the students completed preand posttests containin...
