“…This large spike in accumulation rates at RFGC_17PC_B occurred before mining began around this site in the late 1980s. The increase in accumulation rates around 30 years BP are likely from the strip mining that occurred within the watershed, there should have been a large increase in sediment loading around this site due to the large amount of mine spoil produced (Ramani 2012). This should show that the site has been net depositional, which is supported by both 137 Cs and 210 Pbex sedimentation ratios (Tables 2 and 4).…”

“…A surface is a mining category where materials are extracted from the terrain surface, or near it [117]. Minerals can be gathered from the surface or obtained digging vertical benches, which leaves structures that resemble walls in the relief.…”

Wearable device requirements currently vary from soft to hard real-time constraints. Frequently, hardware improvements are a way to speed-up the global performance of a solution. However, changing some parts or the whole hardware may increase device complexity, raising the costs and leading to development delays of products or research prototypes. This paper focuses on software improvements, presenting a tool designed to create different versions of operating systems (OSs) fitting the specifications of wearable devices projects. Authors have developed a software tool allowing the end-user to craft a new OS in just a few steps. In order to validate the generated OS, an original wearable prototype for mining environments is outlined. Resulting data presented here allows for measuring the actual impact an OS has in different variables of a solution. Finally, the analysis also allows for evaluating the performance impact associated with each hardware part. Results suggest the viability of using the proposed solution when searching for performance improvements on wearables.

“…It is safer because it doesn't involve workers going underground, lessening or eliminating the dangers of exposure to explosives, and death from mine accidents such as cave-ins. Mechanically, surface mining is easier to operate because heavy equipment and vehicles can move freely to mine and process gold; drilling, blasting, loading and hauling (Ramani 2012).…”

The article draws on the insights of political ecology to illuminate the politics shaping the enforcement of environmental regulation in the mining sector of Ghana. We argue that the Ghanaian state uses strong-arm measures against artisanal and small-scale mining (ASM) operators, particularly, the subaltern classes engaged in the industry for survival. Periodically, the state deploys the military and the police to clamp down on ASM for destroying the environment, but treats with kid gloves foreign companies engaged in large-scale mining (LSM), wreaking similar disastrous ecological effects on mining communities. The state believes that LSM by foreign companies is a source of foreign direct investment (FDI) and foreign mining companies should be incentivized to come and stay in the country. Presented in broad-brush strokes as illegal (galamsey), the Ghanaian state sees ASM as an environmental menace to be fought with all the coercive apparatuses that it can command. Disputing this claim, the article argues that mining-FDI is essentially ecological imperialism, wreaking havoc on the ecosystem of mining communities whose livelihood strategies are in conflict with the accumulation and political interests of foreign mining companies and the Ghanaian political class respectively. The article demonstrates that concerns over the harmful impacts of mining on the ecology of Ghana are neither class-neutral nor free of politics. They are rather highly imbricated in power structures and relations, in which the interest of the ruling class is supreme in the enforcement of environmental regulations in Ghana. The paradox of the biases of the Ghanaian state against ASM, particularly ASM operated by its own citizens for survival, and in favor of foreign mining companies engaged in LSM for profits, is explained with the insights of ecological imperialism.Keywords: Large-scale mining, artisanal and small-scale mining, Operation Vanguard, Ghanaian state biases, ecological imperialism
