The development and evaluation of brake pads using groundnut shell (GS) particles as substitute material for asbestos were carried out in this study. This was with a view to harnessing the properties of GS, which is largely deposited as waste, and in replacing asbestos which is carcinogenic in nature despite its good tribological and mechanical properties. Two sets of composite material were developed using varying particle sizes of GS as filler material, with phenolic resin as binder with percentage compositions of 45% and 50% respectively. Results obtained indicate that the compressive strength and density increase as the sieve size of the filler material decreases, while water and oil absorption rates increase with an increase in sieve size of GS particle. This study also indicates that the cost of producing brake pad can be reduced by 19.14 percent if GS is use as filler material in producing brake pad. The results when compared with those of asbestos and industrial waste showed that GS particle can be used as an effective replacement for asbestos in producing automobile brake pad. Unlike asbestos, GS-based brake pads are environmental friendly, biodegradable and cost effective.

This article explores the ecological potential in Job 14:7–12. The metaphor in Job 14 praises the life-giving potential of water to revive a dead tree before presenting its transient character, similar to human life. The article investigates the question of why the author of Job finds it appropriate to use water and water-related images to contrast the potential of water to revive a dead tree with the transient mortals who disappear at death like great bodies of water in times of drought. Using elements of historical, critical, and literary approaches, as well as metaphor theory, and applying the Earth Bible Principle of intrinsic worth, this article argues that water should not be viewed as a limitlessly renewable resource, but a precious gift requiring responsible management.

Densification by greening, or what we can learn from Singapore (essay) Singapore, a city-state with a high population density, wants to give its population, its tourists and its economy a living and livable city and has developed the concept of the Garden City. Parks, nature reserves, forest, green corridors, trees, botanical gardens, horizontal and vertical greening of buildings, as well as popular participation, are all important for this vision of the city. Singapore is counting on dense construction alongside “greening” and biodiversity. Let us be prepared to learn from Singapore's example! Our land is also a non-renewable resource. To protect our ever more limited agricultural land, we should renounce any extension of building land, and free ourselves from the expanding carpets of suburban development. Let us build multiple urban neighbourhoods with mixed use and more biodiversity. Let us develop new types of communal gardens. Urban gardens in the widest sense – from private gardens to garden cooperatives, to parks and botanical gardens – are a part of our living space. The city should be our garden.
