This study aims to create composites from millet husks, rice husks, and recycled EPS, using a manufacturing method that involves dissolving the polystyrene in a solvent followed by cold pressing. Various particle sizes and two binder dosages were investigated to assess their influence on the physico-mechanical properties of the composites. The mechanical properties obtained range from 2.54 to 4.47 MPa for the Modulus of Rupture (MOR) and from 686 to 1400 MPa for the Modulus of Elasticity in Bending (MOE). The results indicate that these composites have potential for applications in the construction sector, particularly for wood structures and interior decoration. Moreover, surface treatments could enhance their durability and mechanical properties. This research contributes to the valorization of agricultural and plastic waste as eco-friendly and economical construction materials.展开更多

The construction of characteristic towns in different regions needs to pay attention to regional differentiation. At present, the research on characteristic towns focuses on the developed the developed central and eastern regions. There are still few studies on characteristics towns in underdeveloped areas. Starting from the analysis of the concept of the characteristic town, this paper sorted out the general situation of the construction of characteristic towns in China based on the existing research literature, selected Ganzhou City for research, pointed out there were "two restrictions and two singles" in the construction of characteristic towns in Ganzhou City, and clarified that the characteristic towns of Ganzhou City should adhere to the construction path of "two characteristics and two integrations", with a view to providing a useful reference for in Ganzhou City the construction of characteristic towns, industrial transformation and upgrading, and poverty alleviation in such underdeveloped, resource-based cities.展开更多

Design: Quasi-experimental, six-month intervention with an evaluation of dietary consumption, habits, and practices and use of the school-based food garden among the 3rd to 5th grade students. Setting: Two municipal schools in a low-middle income district in Santiago de Chile;one with a school garden intervention and a control school without a garden. Subjects: 155 third to fifth grade children, 63 in the intervention school and 92 in the control school (average age 10 years old, 58% boys). Results: In the intervened school, there was a significant improvement in the children’s dietary habits, such as peeling and slicing fruit (p < 0.05), making sandwiches (p < 0.05), and increased motivation to cook (p < 0.05). Fruit purchases at the school rose from 4% to 37% (p < 0.05) by the end of the intervention. Interest in growing vegetables or fruits at home increased from 48% to 70% (p < 0.05). The school children at the intervention school significantly increased their knowledge about 16 of 21 garden crops (p < 0.05), expanding the spectrum of the vegetables they can consume. There were no significant changes in the control school. Conclusions: The school-based food garden was effective in achieving change in dietary habits and practices among the third to fifth grade children. The project should be carried out for a longer period of time, so that the changes will be reflected in the students’ food consumption and nutritional status.展开更多
