t. ikawa obtained an ordinary differential equation for the circular helix. recently, the helix havebeen investigated by many differential geometers such as t. ikawa, h. balgetir, m. bektas, m. ergut, n.ekmekci and h. h. hacısalihoglu. in this paper, making use of this author’s methods, we obtainedcharacterizations of helix for a curve with respect to the frenet frame in 3-dimensional galilean ...

Perceived slant produced by size disparities in random-dot displays was measured by tactile matching. For a 60 deg surface, slant produced by vertical-size disparity (the induced effect) was opposite to that produced by horizontal-size disparity. Overall-size disparity produced a little slant. With small displays, effects of horizontal and vertical disparities were reduced but not those of over...

Visuomotor localization in the presence of slant was measured. Five subjects pointed at the center LED of an array of five LEDs viewed monocularly. Pointing was open-loop. The LEDs were separated by 1.5, 3.0, or 4.5 cm. The array was rotated about a vertical axis coincident with the center LED to slant the array from -50 degrees to +50 degrees. LED separation had no effect. A small linear relat...

We investigate how editorial slant—defined as the quantity and tone of a newspaper’s candidate coverage as influenced by its editorial position—shapes candidate evaluations and vote choice. We avoid various methodological pitfalls by focusing on a single Senate campaign in a single market with two competing, editorially distinct newspapers. Combining comprehensive content analyses of the papers...

hedera helix  is widely used to treat bronchial asthma for many years. however, effects of this herb on lung histopathology is still far from clear. we aimed to determine the effect of oral administration of hedera helix on lung histopathology in a murine model of chronic asthma. balb/c  mice  were  divided  into  four  groups;   i  (placebo),  ii  (hedera  helix), iii (dexamethasone) and iv (c...
