Research ArticleOpen accessEvery word in the titlePhysical and Mechanical Properties of Concrete using Recycled Clay Bricks as Coarse AggregateMohammad Yasir Abdul Hakim, Mohamed El-Zeadani, Siti Aminah OsmanRising construction waste due to demolition work, natural disasters, and development is becoming a prominent issue. To tackle this, Recycled Crushed Brick Masonry Aggregate (RCBMA) can be an ideal replacement for the limited Natural Coarse Aggregates (NCA) in the production of concrete, potentially assisting in managing construction waste and reducing the depletion of NCA. As such, this study focused on … …American Journal of Engineering and Applied Sciences, Vol. 15, Issue 1 · 4 Apr 2022 · 7,594 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhysical, Chemical, Microbiological and Parasitological Parameters in a Composting System of Vegetable Solid ResiduesFrancisco Rafael Martins Soto, Maira Oliveira Silva, Ramieri Moraes et al.This work aimed to evaluate the physical, chemical, microbiological and parasitological parameters in a composting system of Vegetable Solid Residues (VSR). The work was carried out during four months and was constituted of a compost bed of 12 m3 of volume and the proportion used for its filing was of 6:1 (VSR: Sawdust).

Di ToreMIUR enacted last year the new Guidelines of Physical Education and Sport to improve the sport activity into the school through the sport school association and gives, for this aim, only 33% of amount of economical resources that, in the past years, allocated for extra activity of physical education and sport. From a case study to compare data between 2 … …Journal of Social Sciences, Vol. 9, Issue 1 · 15 May 2013 · 7,126 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhysical Properties of Rice Residues as Affected by Variety and Climatic and Cultivation Onditions in Three ContinentsA. E. Ghaly, Bingxi Li, Yaning ZhangRice husk and straw are by-products of rice cultivation and processing industry and can be used as an energy source. Proper understanding of the physical properties of rice residues is necessary for utilizing them in thermochemical conversion processes such as gasification and combustion. The physical properties (moisture content, particle size, bulk density and porosity) of rice husks and straws obtained … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 29 Aug 2012 · 11,970 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePhysical Properties of Corn ResiduesYaning Zhang, A. E. Ghaly, Bingxi LiCorn residues (cobs, leaves and stalks) are abundantly available renewable materials that can be used as an energy source in gasification and combustion systems. Proper understanding of the physical properties of these materials is necessary for their use in thermochemical conversion processes. The physical properties (moisture content, particle size, bulk density and porosity) of corn cobs, leaves and stalks were … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 19,333 accessesView PDFCite
