On the investigations of galaxy redshift periodicity

In this article we present a historical review of study of the redshift periodicity of galaxies, starting from the first works performed in the seventies of the twentieth century until the present day. We discuss the observational data and methods used, showing in which cases the discretization of redshifts was observed. We conclude that galaxy redshift periodisation is an effect which can really exist. We also discussed the redshift discretization in two different structures: the Local Group of galaxies and the Hercules Supercluster. Contrary to the previous studies we consider all galaxies which can be regarded as a structure member disregarding the accuracy of velocity measurements. We applied the power spectrum analysis using the Hann function for weighting, together with the jackknife error estimator. In both the structures we found weak effects of redshift periodisation.Comment: 10 pages, 4 figures, to be published in Part. and Nucl. Lett. 200

Management of the diabetic patient in a resource-constrained environment

A century ago diabetes was virtually unknown in Africa. Currently 10 million people are living with this disease in Africa and the number is predicted to double by 2025. Type 2 diabetes accounts for 85 to 95% of all cases in the region. The main factors responsible for the rapid increase in the prevalence of diabetes in sub-Saharan Africa are an aging population, unhealthy diet, overweight and obesity, and a sedentary lifestyle, closely related to rapid urbanisation of the population in the region
