Suppose A, B, C, D, E, F are points and L is a line other than the line at infinity. This work examines cases in which a translation D′E′F ′ of DEF in the direction of L is perspective to ABC, in the sense that the lines AD′, BE′, CF ′ concur.

This study examines the psychometric properties of the Test of Gross Motor Development-2 (TGMD-2) in children with visual impairments (VI). Seventy-five children aged between 6 and 12 years with VI completed the TGMD-2 and the Movement Assessment Battery for Children (Movement ABC). The internal consistency of the TGMD-2 was found to be high (alpha = 0.71-0.72) and the interrater, intrarater, a...

acid-binding capacity (abc) of a feed is the amount of acid required to reduce the ph of feed to a special level such as 3. all poultry feed ingredients used in this study were collected from feed mills in iran. the ph and abc were determined using the standard methods in deionized and magnetized water at room and body temperatures. the ph of most feed ingredients was raised in magnetized water...

Artificial Bee Colony (ABC) algorithm was firstly proposed for unconstrained optimization problems on where that ABC algorithm showed superior performance. This paper describes a modified ABC algorithm for constrained optimization problems and compares the performance of the modified ABC algorithm against those of state-of-the-art algorithms for a set of constrained test problems. For constrain...

Falls are common in older subjects and result in loss of confidence and independence. The Falls Efficacy Scale (FES) and the Activities-specific Balance Confidence scale (ABC) were developed in North America to quantify these entities, but contain idiom unfamiliar to an older British population. Neither has been validated in the UK. The FES and the ABC were modified for use within British cultu...

background and aim: disequilibrium is a common complaint in the elderly. the activities-specific balance confidence (abc) scale is a suitable tool for assessing the level of confidence in balance whilst performing daily activities. the purpose of the study was translation, cultural adaptation and evaluation of the reliability and validity of the activities-specific balance confidence scale for ...

To the Editor: The recent review by Waters and Nelson ‘Are all nonthymidine analogue backbones appropriate for treating antiretroviral-naı̈ve patients?’ (1) states incorrectly that the rates of hypersensitivity (HSR) in the Zodiac Study were significantly higher with abacavir (ABC) once daily than with ABC twice daily (8 vs. 5%, p < 0.02). In fact, the rates of suspected ABC HSR in the Zodiac St...
