To recover and recycle materials to be reused to build and operate a sustainable dwelling house is a new alternative using a urine-powered cell to produce hydrogen, wheat straw walls and paper plaster walls.Hydrogen from the urinepowered cell can be used as a biogas substituting conventional gas in stoves and boilers used to cook and heat water respectively.Constructing and applying wheat straw walls and paper plaster to obtain ±10°C inside the rooms in winter and summer will provide a comfortable environment inside a dwelling house without air conditioning.Residents will save money by building sustainable dwelling houses and also will stop paying high energy bills.The environment and the general population will gain by using this alternative construction and operation system.

THE IMPORTANCE OF MANUFACTURING DRAWINGS IN THE DESIGN PROCESS: A DIDACTIC CONTRIBUTION TO ENGINEERING EDUCATION Abstract uring the direct design or reverse engineering process of products and machinery, various geometric and manufacturing information is generated according to the phases or stages of development applied during a project in different subjects. Much of this information is not used or lost and students face various problems when generating manufacturing drawings. This article discusses the importance of manufacturing drawings during the direct design process and its implications for engineering education. To generate the design information, the concept of manufacturing primitive and a classification of the manufacturing drawings that follow the stages of direct design are applied. It is using a case study to show the process of generating and documenting the information. The importance of transmitting knowledge to the student is necessary for their academic and professional training. Using tools that are actually used in industrial practice within their processes. Improving the results of students in their subjects and in academic or professional stays. Currently, this acquired knowledge has also been important in academic exchanges because the same way of working is being implemented worldwide.

The Nikola Tesla Constant and Its Relation to the Circumference Inscribed in a Square
(Scientific Research Publishing, 2024) Javier Mendoza Navarrete; José Ismael Ojeda Campaña; Huetzin Perez; Gabriel Luna-Sandoval; Víctor Verdugo; Ricardo Jiménez Garcia
This research work relates the surface of a square and the area circumscribed by a circle, resulting in a value called Nikola Tesla constant. This constant starts with the calculation of the areas of the square and the inscribed circle, giving a ratio of 9/40 and from which a residual area of the area proportions of the geometric figures described is obtained. Plotting smooth curves, particularly those in round shapes, can be represented efficiently with the use of Nikola Tesla constant, reducing complex mathematical calculus.
