We present a study of the main bulk properties (susceptibility, magnetization, resistivity and specific heat) of CePt3B1−xSix, an alloying system that crystallizes in a noncentrosymmetric lattice, and derive the magnetic phase diagram. The materials at the end point of the alloying series have previously been studied, with CePt3B established as a material with two different magnetic phases at low temperatures (antiferromagnetic below TN = 7.8 K, weakly ferromagnetic below TC ≈ 5 K), while CePt3Si is a heavy fermion superconductor (Tc = 0.75 K) coexisting with antiferromagnetism (TN = 2.2 K). From our experiments we conclude that the magnetic phase diagram is divided into two regions. In the region of low Si content (up to x ∼ 0.7) the material properties resemble those of CePt3B. Upon increasing the Si concentration further the magnetic ground state continuously transforms into that of CePt3Si. In essence, we argue that CePt3B can be understood as a low pressure variant of CePt3Si.

We compared the immediate effects of a cool-down strategy including an inverted body position (IBP: continuous 30-s alternations of supine and IBP) after a short period of an intense treadmill run with active (walking) and passive (seated) methods. Fifteen healthy subjects (22 years, 172 cm, 67 kg) completed three cool-down conditions (in a counterbalanced order) followed by a 5-min static stretch on three separate days. Heart rate, energy expenditure, blood lactate concentration, fatigue perception, and circumference of thighs and calves were recorded at pre- and post-run at 0, 5, 10, 20, and 30 min. At 5 min post-run, subjects performing the IBP condition showed (1) a 22% slower heart rate (p < 0.0001, ES = 2.52) and 14% lower energy expenditure (p = 0.01, ES = 0.48) than in the active condition, and (2) a 23% lower blood lactate than in the passive condition (p = 0.001, ES = 0.82). Fatigue perception and circumferences of thighs and calves did not differ between the conditions at any time point (F10,238 < 0.96, p < 0.99 for all tests). IBP appears to produce an effect similar to that of an active cool-down in blood lactate removal with less energy expenditure. This cool-down strategy is recommended for tournament sporting events with short breaks between matches, such as Taekwondo, Judo, and wrestling.

Carbon fibers are considered as one of the promising heating elements in various industrial applications because of their excellent thermal stability and electrical conductivity.
