Readily prepared copper nanoparticles were found to catalyse the 1,3-dipolar cycloaddition of azides and alkynes up to rates comparable to those of microwave chemistry. Both the preparation of the nanoparticles and the click reaction are carried out under mild conditions,…

Study of educational experiences and needs of school nurses involved in delivering sex and realtionships education in one Primary Care Trust in England, This paper reports a study of the involvement of school nurses, in one primary care trust (PCT)…

In this paper we study the distribution of the zeros of each function G_{n}(z)≡1+2^{z}+...+n^{z}, n≥2, which approaches the Riemann zeta function for Rez<-1, and is closely related to the solutions of the functional equations f(z)+f(2z)+...+f(nz)=0. We determine the density of…

The different transitions and reactions involved in the thermal processing of ternary EVA-PE-ADC mixtures, with different concentrations of polyethylene (PE) and azodicarbonamide (ADC), used as foaming agent, have been studied by means of differential scanning calorimetry (DSC).
The effect of…

Based on the practical experiences of the authors through their work on a LEONARDO project, this paper focuses on the internationalisation process within small and medium sized enterprises and in particular, the key role of the attitudes and behaviour of…

In male high-level long-distance runners over 10,000 m, a positive association between both the front thigh and medial calf skin-fold thickness and running performance has been demonstrated. It is assumed that the thickness of skin-folds of the lower limb is…

The purpose of this study was to describe the distribution of different swimsuits models used by male swimmers during all the finals at the 13th FINA World Championships, being held at Rome in 2009. Simultaneously, it was intended to verify…

The purpose of this study was to determine the reliability of the Biodex Balance System in elderly. Forty-five subjects aged 66±5.5 years old and weight 71.6±9.8 kg were tested on the Biodex Balance System. In order to calculate the reliability,…

In this article I intend to highlight some of the main ideas in Paton’s ideology in order to understand what made him an outstanding person in the white minority during the apartheid period; it is also intended to highlight what…

Physiological abnormalities resulting from death of dopaminergic neurons of the central nervous system in Parkinson's disease also extend to the retina, resulting in impaired visual functions. In both parkinsonian patients and animal models, low levels of dopamine and loss of…
