Evolution of the Monkey Crouch T. PFAU ET AL. (“MODERN RIDING STYLE IMPROVES HORSE RACING times,” Brevia, 17 July, p. 289) nicely document the effectiveness of the “monkey crouch” riding style on race times and horse-jockey biomechanics. This style produced measurable speed benefits to winning race times at the English Epsom Derby Stakes (1900–1910). The change in riding style across a decade o...

In the title compound, C2H5NO2·C8H6O4, the glycine mol-ecule exists as a zwitterion (2-aza-niumyl-ethano-ate) with a positively charged amino group and a negatively charged carboxyl-ate group. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds link the components into layers parallel to the ab plane. The central part of each layer is composed of hydrogen-bonded glycine zwitterions, while phthalic a...

background: academic success depends on curriculum planning and goals- setting, choosing suitable teaching methods, considering students' learning style and the teacher and the manner in which material is presented and effective time management. learning style is the processing of information and comprehension. if teachers present contents in a style that matches a student’s preferred learning ...

This study examines a troubling phenomenon occurring recently in several Latin American economies: a marked slowdown in bank credit to the private sector. Based on the study of five countries (Argentina, Bolivia, Colombia, Peru, and Mexico), we first document the magnitude of the problem, asking how severe and prolonged has the slowdown been and how this behavior compare with the past? Second, ...

We present MERLIN, global VLBI and VLBA observations of the high-luminosity, compact steepspectrum quasar B1524−136 at cm wavelengths. These observations reveal well-defined radio jets on both sides of the active nucleus, a situation which is almost unique amongst high-luminosity radio quasars. However, the radio jets on opposite sides are very dissimilar, and the overall radio structure appear...

The three-dimensional structure of pectate lyase E (PelE) has bee? determined by crystallographic techniques at a resolution of 2.2 A. The model includes all 355 amino acids but no solvent, and refines to a crystallographic refinement factor of 20.6%. The polypeptide backbone folds into a large right-handed cylinder, termed a parallel @ helix. loops of various sizes and conformations protrude f...

Single crystals of dizinc tellurium dibromide trioxide, Zn(2)(TeO(3))Br(2), were synthesized via a transport reaction in sealed evacuated silica tubes. The compound has a layered crystal structure in which the building units are [ZnO(4)Br] distorted square pyramids, [ZnO(2)Br(2)] distorted tetra-hedra, and [TeO(3)E] tetra-hedra (E being the 5s(2) lone pair of Te(4+)) joined through sharing of e...

objectives in this section, we studied dietary and other factors related to the effect of lifestyle in type 2 diabetes. these factors may affect the incidence of type 2 diabetes which could be corrected by lifestyle modifications. background prevalence of type 2 diabetes is increasing rapidly worldwide. recent data is reprehensive of increasing diabetes prevalence from 285 millions in 2010 (6.4...

We present and discuss observations made with MERLIN and VLBI at 1.7 and 5 GHz of the two CSS quasars 3C 43 and 3C 298. They show quite different morphologies, the former being a very distorted triple radio source, the latter a small FRII type object. Relativistic effects and structural distortions are discussed. Source ages are evaluated to be of the order of ≈105 years, therefore 3C 43 and 3C...
