Tُhe process of the emergence and formation of a work of art has always been the concern of artists and researchers in art studies. The creation of artwork has also been the subject of educational programs due to its technical aspects. This underscores the importance of studying the path of the creation of a work. This is possible through the genetic criticism and its methodological feasibility....
Large-scale beamforming with radio interferometers has the potential to revolutionize science done pulsars and fast bursts by improving survey efficiency for these sources. We describe a wide-field beamformer MeerKAT telescope outline strategies optimally design such surveys. A software implementation of techniques, ${\rm M{\small OSAIC}}$ is introduced its application in presented. show initia...
BACKGROUND Peak magnetic field exposure was associated with increased risk of miscarriage in 2 recent studies. Reduced physical activity levels in healthy pregnancies may affect measured exposure and thus bias results. METHODS We recruited 100 pregnant women to wear an Actigraph accelerometer and EMDEX magnetic field monitor for a 7-day period. We evaluated the association between physical ac...
in this thesis, a new optically active poly(amide-imide) (pai) was synthesized by the indirect polycondensation reaction of the l-phenylalanine based diacid chloride and 4,4?-diaminodiphenylether in the presence of triethylamine in n-methyl-2-pyrrolidone. the formation of pai was confirmed by ftir, 1h nmr and elemental analysis. in next step, the surface of titanium dioxide (tio2) nanoparticles...
the construct of self-efficacy has received increasing attention in research over the past two decades. many studies have been carried out 1.3 significance of the study this study has pedagogical implications since improving students’ self- efficacy and autonomy is important for promoting actual performance on classroom academic tasks. in academic settings, it has been shown that self-effi...
چکیده کنه تارتن دو لکه ای tetranychus urticae koch یکی از چندخوارترین آفات شناخته شده محصولات کشاورزی دنیا به حساب می آید. در این بررسی جمعیت تخم و مراحل فعال این کنه در شرایط آلودگی طبیعی و مصنوعی در برگ های 8 رقم لوبیا در سال 1392 در گلخانه و مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه ارومیه موردمطالعه قرار گرفت. آزمایش به صورت طرح کاملاً تصادفی برای شرایط مزرعه در10 تکرار و برای شرایط گلخانه ای...
detailed petrographic, geochemical and strontium isotope studies, combined with field observation and rnicrofacies investigations indicate that syngenetic celestite at the base of asmari formation at the bangestan anticline, behbahan region, was deposited directly from tertiary seawater in an intrasupratidal to supratidal environment. during diagenesis, the precipitated celestite underwent seve...
Background and purpose: Dental caries are highly prevalent and their exact detection at initial stages is necessary. The laser-based DIAGNOdent device is used to detect these caries. The aim of this study was to assess the level of agreement between visual observation, bitewing radiographs, and DIAGNOdent system in detection of proximal caries in clinical applications. Materials and methods: I...
in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
