05), with no further changes at V(max). Conclusions: Elite skiers control DP speed by increasing both poling frequency and cycle length; the latter is achieved by increased pole force despite reduced poling time. Adaptation to higher speeds was assisted by an increased range of motion, smaller angle minima, and higher angular velocities in the elbow, the hip,
and the knee joints.”
“A sustainability issue for the rain forest in the corridor of Fianarantsoa (Madagascar) is to preserve the forest while ensuring the development of the local population. The aim of this paper is to determine whether the current situation is sustainable or not according to different action policy selleck products possibilities. We propose a general procedure based on viability analysis: Translation of sustainability issues into constraints on the system state; elaboration of a mathematical model of system evolution rules in the form of controlled dynamical system; computations of the viability kernels according to different action policy possibilities. Among control variables, we focus on monetary transfer. Without monetary transfer, we show that the current HIF-1 pathway situation of the rain forest corridor is not sustainable in our mathematical
modeling framework. We then estimate the minimal maximal amount
per year necessary to make the current situation sustainable. (C) 2013 Elsevier Inc. All rights reserved.”
“The structure of poly((2-dimethylamino)ethyl methacrylate)/sodium dodecylsulfate complexes in TPX-0005 cost water was investigated as a function of poly((2-dimethylamino)ethyl methacrylate) concentration at a fixed sodium dodecylsulfate concentration using small angle neutron scattering. When either hydrogenated or deuterated sodium dodecylsulfate was added to poly((2-dimethylamino)ethyl methacrylate) solutions in D2O, a peak was observed in the small angle neutron scattering which was characteristic of charged micelles. This peak shifted to higher q in both cases as poly((2-dimethylamino)ethyl methacrylate) concentration increased, indicating that the size and shape of micelles changed due to favorable interactions between poly((2-dimethylamino)ethyl methacrylate) and sodium dodecylsulfate. The small angle neutron scattering intensity of the micelles in the polymer/surfactant solutions was measured at the condition where poly((2-dimethylamino)ethyl methacrylate) was contrast-matched. It was possible to obtain information about the structure of the micelles using the Hayter-Penfold model.
