The Implementation of 3D Printing in Engineering Education in the Field of Hydraulic and Pneumatic Components.

The implementation of three-dimensional (3D) printing for education in different fields brings numerous advantages that make learning easier for students. Also, it changes the model of students' participation in the teaching process so that they become active participants. This article considers the involvement of 3D printing in the teaching process in the field of hydraulic and pneumatic components by using the developed methodology.

Characteristics of Biogas Production and Synergistic Effect of Primary Sludge and Food Waste Co-Digestion.

Unlabelled: Co-digestion implementation in wastewater treatment plants enhances biogas yield, so this research investigated the optimal ratio of biodegradable waste and sewage sludge. The increase in biogas production was investigated through batch tests using basic BMP equipment, while synergistic effects were evaluated by chemical oxygen demand (COD) balance. Analyses were performed in four volume basis ratios (3/1, 1/1, 1/3, 1/0) of primary sludge and food waste with added low food waste: 3.

Integrating energy and environmental management in wood furniture industry.

As energy costs continue to rise, industrial plants (even those of energy nonintensive industries such as furniture industry) need effective way to reduce the amount of energy they consume. Besides, there are a number of economic and environmental reasons why a company should consider environmental management initiatives. This paper provides a detailed guideline for implementing joint energy and environmental management system in wood furniture industrial company.
