Sir, It was good to see Dr Ni Brolchain's interesting study of children with special educational needs (February Journal, p.56). They form a small but important subgroup of a practice child population. I suspect these children and their families may well have higher consultation rates than a control group without special educational needs. I trained for general practice (including nine months i...

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 ...

[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.

We study Ni 80 Fe 20-based permalloys with the relativistic spin-polarized Korringa-Kohn-Rostoker electronic structure method. Treating the compositional disorder with the coherent potential approximation, we investigate how the magnetocrys-talline anisotropy, K, and magnetostriction, λ, of Ni-rich Ni-Fe alloys vary with the addition of small amounts of non-magnetic transition metals, Cu and Mo...
