Cassava leaves, which usually contain large quantities of cyanogenic glycosides, were processed into a Zairian traditional vegetable sauce "Mpondu" by simple methods which included blanching (10 min), mashing and then boiling for 20-80 min. These methods enhanced the detoxification of the leaves, with blanching alone resulting in the loss of 57% of the free (non-glycosidic) cyanide content and ...

Since the development bloom in unconventional reservoirs in North America, total organic carbon (TOC) has become a more essential parameter, as the indicator of the efficiency of these reservoirs. In this paper, by using conventional well logs and NMR log data, the TOC content of an unconventional reservoir in West Africa is estimated. Passy’s, Issler’s, and Schmoker’s methods were used as indi...

Abstract Efficient and economical production in shale reservoirs requires specific knowledge techniques to characterize the fracture network, which consists of both large hydraulic fractures natural fractures. Current research mainly focuses on part, while characterizing is relatively rare due complexity uncertainties distribution reservoirs. This paper proposed a numerical method for this comp...

First Question: Dredging of channels to keep them open to shipping is a recurring and costly activity, especially in cases where channels have to be deepened and maintained to accommodate larger and deeper-draft vessels. There is also the concern of how to dispose of the dredge spoil. How does the Corps balance the cost of dredging and dredge spoil disposal with NEPA requirements and with the e...

Coastal seagrass habitats are at risk from a range of anthropogenic activities that modify the natural light environment, including dredging activities associated with coastal and port developments. On Australia’s east coast, the tropical seagrass Zostera muelleri ssp. capricorni dominates intertidal mudbanks in sheltered embayments which are also preferred locations for harbors and port facili...

Tight sandstone reservoirs, as typical unconventional have attracted more and attention worldwide. Compared to conventional the complex microscopic pore structures micro-fractures of tight reservoirs are developed, fluid flow in reservoir is very complicated. Therefore, studying influence fractures on rock topological structure characteristics between matrix critical development reservoirs. In ...
