Comparison of the “Filled” Space of Iranian Painting with the “Empty” Space of The Far East Painting
Almost a particular insight is effective on the artist’s approach in creating quality of space in his painting. In fact, the general atmosphere in any painting is a reporter of artist’s thought and insight. By examining the foundational of ontology in their approach we have found some similarities and differences between the Iranian painting and the Far East painting. The purpose of this study ...
متن کاملSTEM--but no stem.
TWO CONVERGING EVENTS TOOK PLACE ON 9 AUGUST THAT OUGHT TO HAVE THE scientific community scratching its collective head. One of these is an anniversary: On that date in 2001, President George W. Bush signed an Executive Order banning any use of federal funds to support research on stem cells (save, of course, for those 78 preexisting cell lines, only 21 of which are available). That position is...
متن کاملon the equivalence of constructed-response and multiple-choice : stem-equivalent, stem non-equivalent but content equivalent, and stem and content non-equivalent items in reading comprehension using multifaceted rasch
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
Crushing Analysis of Empty and Foam-Filled Cylindrical and Conical Corrugated Composite Tubes
In the present article, a numerical study is performed to investigate the crushing behavior of cylindrical and conical corrugated composite tubes. Different aluminum foams are applied to the proposed structures in order to offer an excellent energy absorption capacity. The crushing behavior of tubes are evaluated in terms of two parameters: SEA (specific energy absorption) and CFE (crush force ...
متن کاملParadoxical form of filled/empty optical illusion.
The filled/empty illusion (Oppel-Kundt) is one of the oldest geometrical-optical illusions, but the determinants of the illusion are not yet sufficiently understood. We studied magnitude of the illusory effect as a function of the height of vertical strokes subdividing a spatial extension of fixed length, using the psychophysical standard-variable matching paradigm. For vertical strokes shorter...
