Modified Dynamometer.
RENEWED interest in ophthalmodynamometry during recent years has revealed difficulties in the actual technique which may be attributable, at least in part, to the dynamometer in common use, designed by Bailliart (1917). Many of these troubles have their origin in the lack of control over the instrument that is so frequently experienced. This is especially common when the operator is in the earl...
متن کاملNew York: The Free Press, 1994 - Henry Mintzberg
Success depends upon knowing future, assessing current abilities and managing change. Mintzberg (1994) provides one of the best--albeit cynical-views of planning in American organizations. His cynicism may be well directed, however, in that he presents ample evidence that most organizations and organizational planners enter into planning with little understanding of the definitions and various ...
متن کاملValidity of the Handheld Dynamometer Compared with an Isokinetic Dynamometer in Measuring Peak Hip Extension Strength
PURPOSE To determine whether the handheld dynamometer (HHD) is an appropriate tool to assess and quantify peak hip extension strength in prone standing position by (1) evaluating the concurrent validity of the HHD versus an isokinetic dynamometer (IKD), (2) establishing the minimal detectable change (MDC), and (3) determining the validity of single-trial versus multi-trial measures. METHOD A ...
متن کاملA new copper acetate-bis(oxazoline)-catalyzed, enantioselective Henry reaction.
A highly enantioselective, nitroaldol reaction catalyzed by a chiral Cu(II) bis(oxazoline) complex has been developed. The reaction scope includes both aromatic and aliphatic aldehydes (15 examples) affording products in good yields and enantioselectivities (87-94% ee). An X-ray structure of the catalyst has been provided along with a rationalization of the sense of asymmetric induction.
متن کاملnew semigroup compactifications via the enveloping semigroups of associated flows
this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.
