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...

The crystal structure of the title compound, [Ni(C(6)H(6)N(4)S(2))(H(2)O)(4)][Ni(C(7)H(3)NO(4))(2)]·3H(2)O, consists of Ni(II) complex cations, Ni(II) complex anions and lattice water mol-ecules. The Ni(II) ions in both the complex cation and anion assume a distorted octa-hedral coordination geometry. O-H⋯O, N-H⋯O and C-H⋯S hydrogen bonds occur in the crystal structure.

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 ...

The 3561 m Vostok ice core sample originating from the subglacial Lake Vostok accretion (frozen lake water) ice with sediment inclusions was thoroughly studied by various means to confirm the presence of the thermophile bacterium Hydrogenophilus thermoluteolus reported earlier in the 3607 m accretion ice sample. PCR and molecular-phylogenetic analyses performed in two independent laboratories w...

In this contribution, the amounts of Ni (nickel) and Al (aluminum) in tilapias (Oreochromis niloticus) were determined using square wave voltammetry (SWV) with glassy carbon working microelectrode with a mercury thin film, platinum counter electrode, and Ag/AgCl reference electrode. Ni was studied through the formation of the dimethylglyoxime-Ni (Ni-DMG) complex, while Al was studied through th...
