Although radix 10 based arithmetic has been gaining renewed importance over the last few years, decimal systems are not efficient enough and techniques are still under development. In this paper, an improvement of the CORDIC (coordinate rotation digital computer) method…

The purpose of this study was of two-fold, firstly, to evaluate the anthropometric profile of Indian inter-university cricketers and, secondly, to search the correlations among the anthropometric characteristics studied (if any). To serve this purpose, twelve anthropometric characteristics were taken…

In this paper we present the theoretical analysis and experimental results of a holographic collimator made in silver halide sensitized gelatin. Diffraction efficiency up to 70% over the whole plate and wave aberration as low as 20-lambda in the maximum…

There is limited data regarding the effects of melatonin on the
activity of neuronal acetylcholine receptors (nAChRs) themselves. This study
analyzes the effects of low concentrations of melatonin on nicotine-evoked
currents from cerebellar granule neurons (CGNs) in culture. Using
electrophysiological…

Purpose – The aim of the paper is to study the reasons for the adoption and certification of quality systems and the subsequent impacts on performance. Design/methodology/approach – The methodology selected is a study based on the perceptions of two…

Background: Perpetrators’ experiences of violence during childhood are considered a risk factor for intimate partner violence (IPV). The objective of this study is to systematically review the characteristics and quality of papers which analyse the association between being battered during…

The kinetics of photosensitive polymer holographic recording materials are examined assuming a material that exhibits nonideal kinetic behavior. Previously, a linear relationship between monomer concentration and polymerization was assumed when deriving the nonlocal polymer-driven diffusion (NPDD) model. This is consistent…

Purpose – This study has a twofold purpose: to identify the competitive strategies and advantages of hotels located in the province of Alicante (Spain); and to inform hotel managers about how some key strategic variables (size, type of hotel management,…

In this paper, we propose an original method to geoposition an audio/video stream with multiple emitters that are at the same time receivers of the mixed signal. The obtained method is suitable when a list of positions within a known…

The use of numerical values for the chemical components of waters from an aquifer as input data for factor analysis is shown to be sometimes more convenient than the use of the logarithms of these figures. Factor analysis was applied…
