Managing coffee processing water in Hawaii
Hawaii is the only state in the USA that grows, processes, and roasts coffee. Coffee processing, however, poses some challenges. One is the processing water, which must be treated, and should be re-used. We surveyed and collected several coffee processing water samples, both influent and effluent, from four small-scale (2-5 ha) coffee farms in Kona on Hawaii (Big Island), and from a large (1200...
متن کاملTITLE : Influence of coffee / water ratio on the final quality of Espresso Coffee . RUNNING TITLE : Coffee / water ratio on Espresso Coffee quality
Espresso Coffee is a poliphasic beverage which physicochemical and sensory characteristics obviously depend on both the selection of ground roasted coffee and the percolation process technical conditions. The aim of this work was to evaluate the influence of coffee/water ratio on the physicochemical and sensory quality of espresso coffee. Furthermore, the influence of botanical varieties (Arabi...
متن کاملFertility and acidity status of latossolos (oxisols) under pasture in the Brazilian Cerrado.
The Cerrado region, with over 50 million hectares of cultivated pasture, provides 55% of Brazilian beef production. Previous investigations have shown that about 70-80% of this pasture is affected by some kind of degradation, leading to low productivity. However, until now, few surveys have been carried out on a regional scale. The aim of the present work is both to assess the fertility and aci...
متن کاملReal-Time Erosion Using Shallow Water Simulation
We present a new real-time hydraulic erosion simulation for Computer Graphics. In our system water runs over the surface and disintegrates the underlying layer of soil. The grit is simulated as a fluid with higher viscosity and moves on the ground of the water pool. When water evaporates, or the dissolved soil exceeds a critical level, the dissolved matter is deposited back on the ground for ac...
متن کاملWater Impingement Erosion of Deep-Rolled Ti64
In this work, the Liquid Impingement Erosion (LIE) performances of deep-rolling (DR) treated and non-treated Ti64 were investigated. Various erosion stages, from the incubation to the terminal erosion stages, could be observed. A full factorial design of experiments was used to study the effect of DR process parameters (Feed Rate, Spindle Velocity, Number of Passes, Pressure) on the residual st...
