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...
This work presents the study of the variability of foF2 and hmF2 at a low latitude station in South America (Tucumán, 26.9°S, 294.6°E; magnetic latitude 15.5°S, Argentina). Ground based ionosonde measurements obtained during different seasonal and solar activity conditions (a year of low solar activity, 2009 and one of high solar activity, 2016) are considered in order to compare the ionospheri...
Ground-based nightglow observations of the atomic oxygen green line at 557.7 nm have been carried out at a low latitude station Kolhapur (17 N), India, during November 2003–April 2004 and December 2004–May 2005. The nocturnal behaviour of OI 557.7 nm intensity and a comparative study with simultaneous OH Meinel band temperature measurements has been presented. OI 557.7 nm intensity and OH tempe...
Temperatures obtained from Sounding of the Atmosphere using Broadband Emission Radiometry (SABER) instrument on board Thermosphere Ionosphere Mesosphere Energetics Dynamics (TIMED) satellite during period 2003 to 2019 are analysed obtain trends in region 50°S 50°N method Empirical Mode Decomposition (EMD). This is used remove long-term oscillations data accurately estimate linear trends. The no...
this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...
the reptile's fauna of sabzevar was investigated during 10 years (2003-2013). in total 43 species belonging to 29 genera, 13families and two orders (squamata and testudines) were collected and identified. the most diverse group in the area is lizards with 23 species, followed by snakes with 18 species and the testudines with one species. the most diverse families are colubridae , lacertidae wit...
a r t i c l e i n f o Global climate models predict that ice will be deposited in tropical regions during obliquity excursions from the current mean obliquity of ~25° to ~35°, but no geological evidence for such deposits has been reported. We document the presence of very small (decameter scale) pedestal craters in the tropics of Mars (the Daedalia Planum– Tharsis region) that are superposed on...
This list of projects is not complete. You can propose your own project based on your research interests, with approval from the instructor. Many of these are programming projects, but the objective is to understand the performance and limitations of existing tools, and to use this knowledge to propose new ideas. Students who are not interested in programmming projects can talk to the instructo...
