The application of lenses combined apac1/60/1/cw with array antennas (also known as dome arrays or dome antennas) to the next generation of terrestrial and satellite communication systems brings a wide range of advantages in terms of improved radiation performance, reconfigurability in the use case, and reduction in power consumption.To facilitate
Sustainability is currently an important part of the building industry.The development of new building constructions and the use of ecological materials is a very popular topic in this area.One example of organic material are natural fibres bio-composites.Bio-composite materials are currently used in the form of laminates mainly used in the sport a
In this paper, to achievement the effect of increase number of heating components arrangement on the rate of heat transfer of natural convection, that others have been less noticed.Therefore, in each stage increase the number of heating components so much the space occupied by them remains constant.Then by calculating the amount of heat transfer in
Background: It is well documented that sub Saharan Africa bears the highest burden of both malaria and HIV.Co infection with both diseases is also well documented.Malaria parasites infecting the placenta lead to inflammation, intervillous fibrin deposition and infarction.This pathologic effect of malaria on the placental has led to the staging of p
In recent years, an important development in flood management has been the focal shift from flood protection towards flood risk management.This change greatly promoted the progress of flood control research in a multidisciplinary way.Moreover, given the growing complexity and uncertainty in many decision situations of flood risk management, traditi
