Variations of wood specific gravity and extractive contents from pith to bark and from base to the top of tree were investigated in a 14-year-old commercial pulpwood species Sterculia setigera Del. Growing in savanna zone in Nigeria. Tree mean specific gravity averaged 0.37; wood at the base had significant higher specific gravity than those at the top while it increased from pith to bark. For extractive content mean value was 1.20% for wood and 1.72% for bark; i[t varied significantly between trees and from base of the tree to the top and from pith to the bark. Extractive content at the butt and breast height is more than double of the value at the top of the tree. The high extractive content at the base is similar to high specific gravity observed for wood samples from the base. Extractive content of the bast was significantly higher than that of the wood. The low specific gravity show possible suitability of the species for paper making in Nigerian paper mills. The wood of Sterculia setigera showed a significant variation between- and within-trees in the two properties considered, though the wood is light with low extractive content; it is however a potential raw material for large scale pulpwood production in Nigeria. 展开更多

For that reason, the river banks have encouraged pioneers to construct their new towns. River transport has always been of vital importance for the economy of various nations. This could be done fhrough descriptive and analytic navigation in rivers and navigation at sea specially in confined waters. Vessel traffic services (VTS) system deals with managing ship traffic and suggesting best routes for vessels at busy and confined waters. Nile traffic service (NTS) as a Nile traffic monitoring system established by rivers protective authorities, can be alike to VTS maximum economic returns coming from fiver routes can be recognized with assistance of Nile traffic services which keep significant river information available for all users at all times. It also helps keep waters safer and more controlled by detecting illegal cargo activities the paper aims to re-plan River Nile for using in navigation and transportation due to its significant importance for a country like Egypt. 展开更多

The difficulties in learning Chinese faced by non-Chinese students are the subjects of concern in the education sector, especially in writing Chinese characters. We write the characters with strokes and dots, more or less strokes or dots will represent different words and different meanings. Students found these very complicated and confused, thus it leads them to lose their motivation and interest in learning Chinese language. From the beginning of the 1990s, I began using origami as one of the activities to promote the teaching of Chinese in the state school in Melbourne Australia with remarkable results. Program got widely reported by Medias. In 1995, I got the "National Excellence in Teaching Awards". After I took up the position as the curriculum development officer in University of Hong Kong in 2007, I worked closely with the teachers and students using origami as the theme base learning in Chinese. It helps to increase their understanding of the radicals and parts, so as to improve their confidence in writing Chinese characters. 展开更多

Advertising revenue is generally regarded as the lifeblood of the mass media since it largely contributes to the financial fortunes of both commercial and so-called public media houses. There is a consensus among political economy scholars that gives advertisers power over media content. It has also been argued that advertisers usually do not associate with ideological enemies. This research therefore sought to find out whether political advertisements especially, during election time, influence media content and whether political advertisers do not associate with media houses they are not ideologically compatible with. During election times, political parties also become big advertisers and newspapers together with broadcasting media compete to get advertisements from political parties so as to boost their financial fortunes. The research focused on the March 29, 2008 Zimbabwe harmonised elections with Network Guardian News a Kwekwe based privately owned community newspaper being used as a case study. This study utilised critical discourse analysis on purposively selected newspaper stories published during the period under study; while in-depth unstructured interviews with editors, reporters from the newspaper and politicians were also conducted to gather information. The findings revealed that in spite of the pro-ZANU-PF Network Guardian News newspaper carrying both MDc and ZANU-PF advertisements, its editorial stance remained hostile to the MDC-T party. 展开更多

Antimicrobial activity of extracts of local plants was evaluated, with two strain i.e E. coil and S. aurri (gram positive and gram negative) microorganisms. The in vitro anti bacterial activity was performed by agar disc diffusion method. The most active antibacterial plants were S. trifiliatus and A. mexicana. The significant antibacterial activity of active extracts was compared with the standered, antimicrobics, streptomycin (10 μg/disc). The results obtained in the present study suggest that S. trifoliatus and A. mexicana can be used in treating diseases caused by the test organism. 展开更多
