Additional Criteria for Playground Impact Attenuating Sand

Falls within children’s playgrounds result in long bone and serious injuries. To lower the likelihood and severity of injury, impact attenuating surfaces (IAS) are installed within the impact area (fall zone). There are three primary IAS materials used, namely: granulated rubber products, wood fibre products, and sand. There is a deficiency with existing IAS test methods in that they do not take account of sand degradation over time. When children use the playground, sand degradation can occur when sand produces fines and smaller particles with low sphericity and angular which fill the voids between the sand particles. These fines and smaller particles tend to bind the sand and lower its impact attenuating performance. This paper proposes an additional IAS test to eliminate sands that degrade above an established threshold rate after installation due to normal usage. IAS degradation properties of fifteen IAS sands were tested including sand particle shape, sand particle distribution, percentage fines and sand particle degradation. This accelerated ageing test method is applicable only to sands and not rubber or wood fibre IAS products. The best IAS sands were sourced from quarries located on rivers that had eroded volcanic outcrops. These sands were shown to degrade the least and had little to no fines, and their particle shape was rounded to well-rounded. The most reliable source for good quality IAS sands on these rivers was on specific bends. The sand mined at these locations consistently had a tight particle size distribution.

Effect Incorporated of Oat and Corn Cob Powder on Physicochemical and Sensory Properties of Putu Piring

The growing consumer demand for healthy food products has turned the interest of industry and researcher in the development of foods enriched with fibre source. Oat and corn cob powder is one of the fibre sources that rich in insoluble fibers, such as cellulose, hemicellulose and lignin which beneficial the consumer in many ways for a healthy diet. The objective of this study was to investigate the effect of oat and corn cob powder incorporation on the sensory acceptability and physicochemical properties of putu piring at different levels of percentage ratio of oat and corn cob (control 0 percent OP: 0 percent CCP A, 0 percent OP: 100 percent CCP B, 30 percent OP:70 percent CCP C, 50 percent OP:50 percent CCP D, 70 percent OP:30 percent CCP E and 100 percent OP: 0 percent CCP F). Physical analysis showed that the colour of putu piring for L* value ranges from 74.17 to 19.76, a* value ranges from 0.23 to 1.90 and b* value ranges from 13.97 to 20.65. Sensory evaluation results showed that putu piring control (formulation A) scored the highest and no significant different (p lower than 0.05) compare followed by 30 percent OP: 70 percent CCP (formulation C) and 50 percent OP: 50 percent CCP (formulation D) in all attributes being evaluated. Proximate analysis showed that putu piring incorporated with oat and corn cob powder has significantly different (p lower than 0.05) in terms of crude fibre content. It is interesting to note that the incorporation of oat and corn cob powder yielded putu piring can improves the nutritive value of the product to become high fibre products.

Spanish Broom Fibres Properties and Extraction for Application in Composites: A Review

The development of a number of natural fibre products for textiles was attempted during the period of Italian autarchy (1935–1943) under the direct support of the Fascist regime. Among these was Spanish broom fibre, which derives from the stem of Spartium junceum, a spontaneous plant in large parts of Italy, especially in the Southern region of Calabria. The extraction of the fibre proved cumbersome though, especially for the hardness of the stem. Therefore, different retting processes were developed, mechanical, chemical and also bacterial, in the latter case through the use of Clostridium felsineum, which proved effective to a point, allowing the production of textiles. The historical events linked to the fall of the dictatorship led to some oblivion and also to the possible loss of archive materials. The objective of this review is to elicit ideas and developments concerning an effective extraction and degumming of Spanish broom fibres and evaluate the more recent applications to the field of biocomposites.

<p>The production of plant fibre products is considered a promising pathway for contributing to people’s livelihoods particularly in developing countries, where economic options might be limited. However, there are limited comparative studies across countries on plant fibre products, making it difficult to examine how local and broader biophysical, socioeconomic, cultural and policy contexts influence craft production patterns in terms of primary plant resources used, products made and contributions to livelihoods. Using household surveys for data collection, this paper presents findings from a comparative analysis of plant fibre craft production and income in three southern African countries, Eswatini, Malawi and Zimbabwe.</p>
