The proximate principles and mineral elements in the wet and dry tissue and peel of Dioscorea bulbifera were determined using standard methods. The proximate principles were analyzed using AOAC methods, the mineral elements namely calcium, magnesium, iron, zinc, copper, sodium and potassium by absorption and emission spectrophotometry and phosphorous by molybdovanadate method. All the parameters analyzed apart from carbohydrate and energy value showed tissue/peel ratios of less than 1.0 which was consistent with the observed significantly lower levels of the mineral elements and proximate principles in the tissue than the peel (p<0.01) excepting carbohydrate and energy value. Additionally, the about constant tissue/peel ratios observed for the mineral elements and some proximate principles such as ash, crude fibre, fat and protein for the wet and dry samples of Dioscorea bulbifera were indicative of the stability of these nutrients and in about the same proportions in the tissue and peel upon drying at 40°C. The nutritional significance of the mineral elements in the tissue and peel of Dioscorea bulbifera was also highlighted in the discussion. © Asian Network for Scientific Information, 2011. Source

With rising numbers of Facebook, Twitter and MXit users, Africa is increasingly gaining prominence in the sphere of social networking. Social media is increasingly becoming main stream; serving as important tools for facilitating interpersonal communication, business and educational activities. Qualitative analyses of relevant secondary data show that children and youths aged between 13 and 30 constitute Africa's heaviest users of social media. Media reports have revealed cases of abuse on social media by youths. Social networks have severally been used as tools for perpetuating crimes such as; cyberbullying and violence against girls and women. This study proposes a 'Culture-centered Approach' to the use of social media in a bid to minimize these cybercrimes and encourage the responsible use of social media amongst African youths. The Culture-centered Approach, which incorporates the tenets of Information Ethics, stresses the need for the respect of the dignity and rights of other online users as well the application of good cultural values and ethical behavior while on social media platforms. © 2013 Springer Science+Business Media Dordrecht.

Background & objectives: The study was aimed at determining the pattern of co-occurrence of species of microfilaraemia between onchocerciasis endemic and sporadic populations. Methods: From every consenting person of one year and above, 50 μl of day and night blood samples were collected and processed respectively with Haemotoxylin and Giemsa as vital stains. Two skin snips (one each from the waist and the shoulder) were also taken from these individuals and processed. Results: Results showed single species microfilaraemia (86.4 and 82.3%), double species microfilaraemia (12.2 and 16.9%) and triple species microfilaraemia (1.4 and 0.7%) for endemic and sporadic populations respectively. All the species had single species microfilaraemia mostly, but Mansonella perstans and Loa loa showed greatest tendency towards double and triple species microfilaraemia. The prevalence of Wuchereria bancrofti microfilaraemia among those positive for Onchocerca volvulus was significantly lower than the overall prevalence of Wuchereria bancrofti. Wuchereria bancrofti microfilaraemia was most common among those who had L. loa microfilaraemia. Wuchereria bancrofti microfilarial intensity was higher among those with M. perstans microfilaraemia than among those positive for any of the other filarial species. Similarly, the intensity of M. perstans microfilaraemia among those positive for W. bancrofti exceeded the overall intensity of M. perstans. Conclusion: It is concluded that there was no definite pattern in mf densities discernible from co-occurrence infections either in the onchocerciasis endemic or sporadic population. There could be varied outcomes of onchocerciasis infection attributable to positive or negative regulatory effects of other pathogens harbored by the victims. Source

This paper focuses on informal language usage by students of Cross River University of Technology, Calabar, Nigeria. This includes the use of slang words from primarily the substrate and superstrate language of the mother tongue (MT) and Nigerian Pidgin (NP) respectively. Participant observation was used for this work including lectures and other forums. Focus is on the speech discourse of students. The NP in particular is a contact language which has grown in stature due to factors of relevance as a common language in a pluralistic society like the Cross River State in particular, and Nigeria in general. Its use has also expanded due to urbanization. The MT has been observed to be influential through direct translation of certain expressions. Findings have shown that the informal use of language by the students has inadvertently affected their competence in standard and formal language use. © Australian International Academic Centre.

This study examined the role of gas flaring in the rapid corrosion of zinc roofs in the Niger Delta Region of Nigeria. Four experimental sites were set up where samples of galvanized iron sheet (popularly called "zinc roofs") were exposed to the atmosphere. The corrosion behaviour of galvanized iron sheet through weight loss determination under different environmental conditions was monitored. A uniform angle of inclination of 22° (which represents the mean angle of inclination of house roofs in the study area) was chosen. The results showed that corrosion was more severe (average readings of 25.89, 34.30, and 21.27 mg) in the three experimental sites that were located near pollution sources such as gas flare station or sea aerosols, than at the controlled site (2.36 mg) that was located far away from pollution sources. It is recommended that government's policy of zero gas flaring for oil companies operating in the Niger Delta by 2010 be pursued with vigour, so as to realize the deadline and subsequently reduce the economic burden currently suffered by the inhabitants of the Niger Delta through frequent replacement of house roofs and incessant illnesses. In addition, individuals and companies operating in the region should avoid bush burning, reduce the rate of fossil fuel consumption by conserving energy, and install catalytic converters in cars and industrial chimneys, so as to reduce emissions. © 2010 Springer Science+Business Media, LLC.
