The prevalence of temporal landmarks has been revealed in a wide range of tasks associated with autobiographical memory, such as recall and dating of personal events. The author examined 3 types of events that have usually been considered landmarks: flashbulb memories, 1st experiences, and reference points in personal histories. The differences between landmark events and nonlandmark events are...
This article explores the heat and mass transfer behaviour of magnetohydrodynamic free convective flow past a permeable vertical rotating cone and a plate filled with gyrotactic microorganisms in the presence of nonlinear thermal radiation, thermo diffusion and diffusion thermo effects. We presented dual solutions for the flow over a rotating cone and a rotating flat plate cases. Similarity var...
A conventional twin-roll caster usually casts strips at a speed slower than 2 m/min and roll load greater kN/mm. vertical-type high-speed can cast aluminum alloy higher 10 smaller 550 N/mm due to the effect of large thermal conductivity copper rolls, compared with that steel rolls. However, properties an strip 140 30 are not clear. In this study, Al–5%Mg were loads 88 using caster. The effects ...
We present unusual retained remnants of hidden conjoined twin of possible abdominal pagus after 21 years who presented with abdomenpain and incidentally have found his forbidden conjoined twin. He presented for many years with a palpable epigastric mass, and recent abdominal pain, early satiety, nausea and vomiting. The mass was a like deformed fetus weighing 815 gr who was anencephalic and dep...
Late Neoproterozoic- Early Cambrian schists exposed in southwest of Zanjan in northwest Iran. Intrusion of Tertiary Korramdaragh monzogranite body within these schists have caused crystallization of porphyroblasts of hexagonal cordierite with cyclic radial sixling twin structure. Hexagonal cordierite consists of six optically sectors. Under microscope with crossed polarized, all of the sect...
در این مقاله به منظور تحلیل الاستیک پوستههای استوانهای تشکیل شده از مواد هدفمند (fgm)، معادلات دیفرانسیل حاکم بر استوانههای جدارضخیم چرخان fgm تحت فشار در حالت متقارن محوری به کمک تئوری تغییر شکل برشی مرتبه سوم (tsdt) استخراج و حلّ عمومی آنها برای شرایط انتهایی دو سرگیردار ارائه شده است. سپس با انجام مطالعه موردی و همچنین ارائه یک حلّ عددی، توزیع جابهجایی و تنش حاصل از حلّ تحلیلی به کمک تئور...
In this work, polypropylene (PP) nanocomposites containing different weight concentration of graphene nanoplatelets (GNP) were prepared by melt-mixing using an industrial-scale, co-rotating, intermeshing, twin-screw extruder. The materials then compression moulded into sheets, and biaxially stretched at stretching ratios (SRs) below the PP melting temperature. effects GNP content biaxial on bul...
Most plastics products are made from a base polymer mixed with complex blends of materials known collectively as additives, to ensure that the physical, mechanical and surface properties of the final product is optimised in all aspects. This will include safer, cleaner product possessing optimal colour and properties. Fine additives such as fillers or coloured pigments are most widely used and ...
OBJECTIVE We sought to review the natural history, pathophysiology, diagnosis, and treatment options for twin-twin transfusion syndrome (TTTS). METHODS A systematic review was performed using MEDLINE database, PubMed, EMBASE, and Cochrane Library. The search was restricted to English-language articles published from 1966 through July 2012. Priority was given to articles reporting original res...
this study introduces the differential transform method (dtm) to analyse the free vibration response of a rotating, closed section, composite, timoshenko beam which features material coupling between flapwise bending and torsional vibrations due to ply orientation. the governing differential equations of motion are derived using hamilton’s principle and solved by applying dtm. the natural frequ...
