For some years, chimpanzees have been observed eating the pith of decaying palm trees of Raphia farinifera in the Budongo Forest, Uganda. The reasons for doing this have until now been unknown. An analysis of the pith for mineral content showed high levels of sodium to be present in the samples. By contrast, lower levels were found in bark of other tree species, and also in leaf and fruit sampl...

The adsorption behavior of formaldehyde has been examined using PAN based activated carbon nanofibers (PACNF). PACNF was prepared through the processes of oxidation stabilization and successive steam activation of electrospun polyacrylonitrile nanofiber (Diameter: avg.800nm, Nanotechnics, South Korea). Among simple heat treated PAN nanofibers in the temperature range of 500~800C, PAN carbon nan...

Chemical ripening of sugarcane is an important component to profitable sugar production in the United States as well as other sugarcane industries throughout the world. Harvesting of sugarcane often begins before the sugarcane reaches the desirable maturity level. This is especially true in the Louisiana sugarcane industry where the window for harvesting is limited because of the risk of freezi...

Sweet potato (Ipomoea batatas) root parenchyma and tobacco (Nicotiana tabacum) stem pith, both known to increase peroxidase activity after excision, differed from each other in their isoperoxidase patterns and in the isoperoxidase responses to injury and exogenous ethylene.In potato root sections, the injury-dependent peroxidase increase was due to an induction of two isoenzymes, as well as to ...

In-depth information on sugarcane germplasm is the basis for its conservation and utilization. Data on sugarcane molecular markers are limited for the Chinese sugarcane germplasm collections. In the present study, 20 start codon targeted (SCoT) marker primers were designed to assess the genetic diversity among 107 sugarcane accessions within a local sugarcane germplasm collection. These primers...

A CFD (Computational Fluid Dynamics) benchmark calculation for a steam blowdown test was performed for 30 seconds to develop the methodology for a numerical analysis of the thermal mixing between steam and subcooled water and to apply it to APR1400 (Advanced Power Reactor 1400MWe). In the CFD analysis, the steam condensation phenomenon by a direct contact was simulated by the so-called condensa...

Sugarcane sector has a strong impact as a wealth generator for Brazil. Several authors discuss the importance of quantifying an agro-industrial system. This article aims to analyze the development of the Brazilian sugarcane sector over the past five years and to assess whether the method of mapping and quantification of agribusiness systems (GESis) is a useful tool for analyzing the economic de...
