Deficiency rickets results from a deficiency of vitamin D that is responsible for deficient calcium absorption, leading to failure of bone mineralization and cartilage bone growth, especially in children. We report the case of a 9-year-old girl who shows signs of rickets. Her family history, which includes similar malformations in several family members, led us to suggest vitamin D-resistant ri...

Hydrocele in adults is a collection of peritesticular fluid between the parietal and visceral layers of the tunica vaginalis testis. An endemic disease in Africa, its cause is either idiopathic or a reaction to filariasis. In the absence of treatment, its volume increases spontaneously. The onset of symptoms justifies treatment. In tropical zones, surgery is the most effective treatment. The te...

The spatial distribution of tropospheric and stratospheric temperature trends for 1979 to 2005 was examined, based on radiances from satellite-borne microwave sounding units that were processed with state-of-the-art retrieval algorithms. We found that relative to the global-mean trends of the respective layers, both hemispheres have experienced enhanced tropospheric warming and stratospheric co...

bovine ephemeral fever (bef) is an acute epidemic disease in cattle and water buffalo, spanning tropical and subtropical zones of asia, australia, and africa. in recent years, bef has been distributed in many provinces of iran and caused economic losses. in this study the sequence encoding the g1 epitope of bovine ephemeral fever virus (befv) g glycoprotein was amplified by pcr, ligated into th...

Solar energy is expected to be the fastest developing of Renewable Energy Sources (RES) in next years. With introduction Distributed Generation into space limited urban areas, need find new solutions that allow installations Photovoltaic (PV) systems cities has become crucial for constant and sustainable energetic development world. This study presents experimental simulation analyses implement...

Understanding the spatial dimensions of hunting and prey population dynamics is important in order to estimate the sustainability of hunting in tropical forests. We investigated how hunting offtake of vertebrates differed in mixed forest and monodominant forest (composed of Gilbertiodendron dewevrei) and over different spatial extents within the hunting catchment around the logging town of Kabo...

Climate change is a negative global externality that threatens economic growth. In our study, we firstly reviewed the transmission mechanisms of climate affecting growth based on existing literature. Secondly, respectively used fixed effect method and panel vector autoregression to test short-run long-run effects 44 countries in six climatic zones Africa, from 2000 2019. The results showed temp...

Abstract Human-induced climate change significantly alters the spatiotemporal characteristics of zones, which drives agricultural land use and ecosystem change. However, detectability shifting zones rate time changes has yet to be adequately addressed at regional-to-local scale. We mapped analyzed temperature precipitation across Kenya during past four decades, linked those shifts in geographic...
