In this work, the hierarchical decomposition methodology was used to conceptually design the production of fuel ethanol from sugarcane. The decomposition of the process into six levels of analysis was carried out. Several options of technological configurations were assessed in each level considering economic and environmental criteria. The most promising alternatives were chosen rejecting the ...

This study models the amount of water stored in the millable stalk as a function of the dry weight of the stalk structures and of the stored sucrose. The correlation was highly significant (r=0.98, n=30). Structural material was equated to the difference between the stalk total dry weight and sucrose. Knowing the effect of the water deficit on the water content of the cane, the deficits were co...

Varieties NCo376 and N14 are the most widely grown varieties in Zimbabwe and are used as control varieties in the selection programme. The success of NCo376 was due to its high yield potential throughout the year and its ability to maintain good yields, even in advanced ratoons. A study was done to compare the performances of N14 and NCo376 in the South-East Lowveld of Zimbabwe, using data from...

Contemporary evolution can shape ecological dynamics at population, community and ecosystem levels. Innovative new experiments with walking sticks confirm this expectation by showing that adaptation to predatory birds has large effects on walking stick population sizes, arthropod communities and herbivory.

An analyt~cal method has been developed which can be used for routine detect1011 and estiinatlon of oligosacchar~des in cane sugar products. Levels as low as 0.01% can be detected and oligosacchaiides have beell found in all m~l l and refinery products. The method IS based on giadient elutlon wlth aqueous ethanol, usiilg a carbon-celite column. Samples of about zoo mg glve good results for most...

on to a heavy wooden mill which is revolved by the bulls moving in a circle round the mill. The old man was bending over the crushing blocks to remove sugar-cane debris when his long hair got undone and was caught in the mill. The bulls continued to move round in a circle which resulted in his hair being wound into the mill. He was dragged round the mill and fruitlessly tugged to get free. His ...

Cane based enterprise is one of the most flourished business in the northeastern region of Bangladesh. The purpose of the present study is to observe the pattern of production of cane based furniture in Sylhet city, identify the prospects and problems, and recommend solutions. The study reveals that most of the cane furniture enterprises (57%) is small and 36% is medium and 7% is large in size....

Five new phenolic compounds, 4-(beta-D-glucopyranosyloxy)-3,5-dimethoxyphenyl-propanone (8), 3-[5-[(threo) 2,3-dihydro-2-(4-hydroxy-3-methoxyphenyl)-3-hydroxymethyl-7-methoxybenzofuranyl]-propanoic acid (12), 2-[4-(3-hydroxy-1-propenyl)-2,6-dimethoxyphenoxy]-3-hydroxy-3-(4-hydroxy-3,5-dimethoxyphenyl)propyl-beta-D-glucopyranoside (13), 4-[(erythro) 2,3-dihydro-3(hydroxymethyl)-5-(3-hydropropyl)...

The StepWatch activity monitor has not been validated on multiple indoor and outdoor surfaces in a population using ambulation aids. The aims of this technical report are to report on strategies to configure the StepWatch activity monitor on subjects using a cane and to report the accuracy of both leg-mounted and cane-mounted StepWatch devices on people ambulating over different surfaces while ...

Primary health cane providers should play a leading role in the medical evaluation and psychological preparation of children before surgery or other procedunes requiring anesthesia. The provider’s goal is to ensure that the child’s medical issues are clearly defined and that the physiologic impact and limitations imposed by each condition are well delineated. The primary care provider’s knowled...
