Ni-Ti shape memory actuators respond to temperature changes with a shape change. Therefore, they are sensors and actuators. They combine large motion, rather high forces and small size, thus providing high work output. They usually consist of only a single piece of metal, e.g. a helical spring, and do not require sophisticated mechanical systems. They of len fit into tight spaces in given desig...

• TVJT: A puppet makes a statement about a story. A child’s task is to reward or correct the puppet based on the statement. • Previous studies: Children allow the long-distance zibun interpretation. Otsu (1990): disproportional salience of potential antecedents (zibun’s picture) Okabe (2008): failure to satisfy Condition of Plausible Dissent (Crain & Thornton 1998) Taro-wa Akira-ga zibun-ni pen...

Tsetse-borne African animal trypanosomiasis remains a serious threat to livestock production in sub-Saharan Africa. The disease limits the full potential of agricultural development in 36 endemic countries of Africa 1,2. In Ni-geria, livestock production is limited by trypanosomiasis as tsetse flies infest about 75% of the nation's land mass 3 subjecting the animal population at great risk of t...

Recently published data on the precipitation of Ni–Zn ferrite powders prepared by the hydrothermal method have been analysed in a manner consistent with Avrami theory. The results indicate that the value of the time exponent is due to the growth of spherical particles in a solution which becomes progressively depleted of reactants. The analysis also indicates that the process can be considered ...

Introduction: The 3.8 km in diameter Steinheim Basin (Baden-Württemberg, SW Germany) is a small, complex impact structure hosted by a sequence of Triassic to Upper Jurassic sandstones, marls, and limestones that build up the Swabian Alb plateau [1]. The specific alignment of the Steinheim Basin, the 24 km in diameter and 14.4 Ma Ries crater, and the Central European tektite strewn field led [2]...

[Ni(L(1))Fe((t)BuNC)4](PF6)2 is a robust Ni(II)Fe(II) complex that undergoes a reversible one-electron reduction. Spectroscopic and theoretical studies show that [Ni(L(1))Fe((t)BuNC)4](+) is an unprecedented Ni(I)Fe(II) species that reproduces the electronic configuration of the Ni-L state of the [NiFe] hydrogenases.

Background: Land and water pollution by heavy metals is a universal issue. Although the pollution affects all countries, but its range and severity vary hugely. The pollution of the marine environment by heavy metals is a worldwide problem. Marine sediments can be sensitive indicators for monitoring contaminants in aquatic environments. Methods: The concentration of 10 elements (As, Cd, Cr, Cu...

The binary A(8)B phase (prototype Pt(8)Ti) has been experimentally observed in 11 systems. A high-throughput search over all the binary transition intermetallics, however, reveals 59 occurrences of the A(8)B phase: Au(8)Zn(dagger), Cd(8)Sc(dagger), Cu(8)Ni(dagger), Cu(8)Zn(dagger), Hg(8)La, Ir(8)Os(dagger), Ir(8)Re, Ir(8)Ru(dagger), Ir(8)Tc, Ir(8)W(dagger), Nb(8)Os(dagger), Nb(8)Rh(dagger), Nb(...
