  Iris Publishers Development of a Modular and Sustainable Yam Pounding Machine Authored   by    Ibhadode Oisehoemomen Abstract This work is focused on the design and production of a yam pounding machine. This machine consists of a shaft, electric motor, stainless steel pot, yam beater or blade, pulley and the frame. Mild steel material and stainless-steel sheet were used in the design on its availability, strength, appearance, and cost and corrosion resistance. A power requirement of 1hp was needed to drive the machine. However, an improvement was made on the size, making it more portable than the existing ones and the use of dampers to minimize vibration with better reliability and working efficiency. The machine was designed, constructed, assembled and tested according to specification. The performance of the machine was evaluated to its highest level of efficiency of 96% and demonstrated by pounding 3kg of cooked yam. The designed machine is far better than...

  Iris Publishers Tendencies and Possible Application Model of the Domed  Skylights in the Construction Sector Authored     by   Egidijus Ruzgys Summary Domed skylights are the most actively used kind of skylight constructions. This article analyzes the main possibilities of domed skylights application, the latest world trends and perspectives are systemized and highlighted. The priority indicators of the efficiency are determined, a model of the possible use of domed skylights with a graphical 2D drawing after the expert survey is developed. The three-layer dome skylight model interconnects a set of characteristics and a complex of integrated technological solutions. In summary, proposals submitted for the representatives of the construction sector, i.e., businesses, building developers, designers and architects, and skylight manufacturers.
