This article describes the feasibility of using smartphones as an alternative light source in endoscopic procedures by comparing it to conventional light sources. Therefore, we used an adapter designed and printed in 3D, combined with an iPhone 6S, ear endoscope L. 50mm diam. 4mm 0 ° and a cardboard as dark anterior. Tests have shown that the illumination is adequate and sufficient, and the results obtained are satisfactory. As a conclusion, this adapter and method finds its place in clinical emergency situations and when endoscopy tower or portable light source might not be available especially in low-and middle-income countries (LMCIs).

For the process of treating organic waste, rotary composters are frequently employed. The amount of energy used to move the organic waste is a crucial factor to consider when designing a composting machine and selecting an appropriate motor. Using a simplified model created by regression approximation from mechanical equations, the power for the movement of organic material can be expressed as a clear and specific function of the composter size, operational parameters (direction of the sun, humidity, etc.), and organic waste qualities. The effectiveness of this model is confirmed with experimental measurements on an industrial rotating composter, yielding satisfactory results and accuracy.
