An alternative method for preparing lithium hexafluorosilicate regarded as an important anode active material in lithium ion battery is proposed. The compound was obtained from lithium ion battery by washing the electrolyte mixture with ethanol and distillation in a glassware reactor. The investigation showed that there was an exchange reaction between the silicon from the glassware and phosphorus of LiPF6 in the ethanol used as the extractant. Ethanol proved suit-able for the synthesis of Li2SiF6 in glassware to enhance water requirement as a condition for the reaction. The compounds obtained from both simple plastic and glassware were character-ized using XRD. The results of the X-ray diffraction patterns confirmed that both Li2SiF6 and LiF were obtained from glassware and plastic respectively. The lattice parameter analysis has the hexagonal structure with space groups P321 and P-3M1 as well as the orthogonal structure with space groups P222 and P2221. It has been successfully shown that the electrolyte solution from the Li-ion battery can be economically and effectively used for the preparation of Li2SiF6 for immediate demand besides the virgin materials and still re-use the ethanol by distillation.

Since the turn of the new millennium, the new media has continued to alter the communication configuration in modern societies. The social media tools have been influencing the way we interact and communicate. These wireless networks have confirmed that our world has indeed become a global village by creating a superhighway for communication possibilities never witnessed in human history. While scholars have explored the roles of some of the new media platforms e.g. Facebook blogging, and twitter for private and public discourses(e.g., Taiwo, 2010; Presley, 2010, 2012), previous studies in the use of SMS in Nigeria have concentrated more on sociolinguistic, lexical, or morphosyntactic features of text messages (e.g., Awonusi, 2004; Chiluwa, 2010). The present study, however, considers aspects of the new media discourse strategies as resources in a second language setting that demonstrate users’ bilingual creativity. It adopts a discursive-semiotic approach in its analytical paradigm to examine how participants, sharing the mobile protocols, deploy linguistic and non-linguistic facilities as well as contextual resources to create relationship and to enact meaning. The approaches of Discourse Analysis (DA) and Semiotics (Schiffrin, 1994; Chandler, 2001) as well as insight from Computer-Mediated Communication (CMC), and Computer-Mediated Discourse Analysis (CMDA)(Herring 2001, 2004; O’Riley, 2005; Herring, 2007) provide the theoretical underpinning for this study. CMC and CMDA, for instance, have been used as tool kits to study and to explain how the new media technologies influence the strategies with which language users within a given virtual sphere engage a wide range of audience through the virtual protocols. The study finds that the use of text messages has opened up creative ways of deploying the resources of a non-native language (English) among bilinguals in Nigeria. The outcome of this innovative and reproduction process confirms the emergence of varieties of new media-based discursive practices in English that reflect the socio-cultural contexts of the communicative event. © Australian International Academic Centre, Australia.

By exactly diagonalizing the Hubbard model for ten electrons on ten sites in a one-Dimensional (1D) ring, we extend the study of Jafari (2008) to more than two electrons on two sites. We equally show the sparsity patterns of the Hamiltonian matrices for four- and eight-site problems and obtain the ground state energy eigenvalues for ten electrons on ten-sites. The technique we employ will be a good guide to a beginner/programmer. © Maxwell Scientific Organization, 2013.

Lymphatic filariasis caused by Wuchereria bancrofti is a serious public health problem in rural communities of Nigeria. The study assessed the prevalence of lymphatic filariasis and associated clinical morbidities in Ado-Odo Ota Local Government Area of Ogun State. Microscopic examination of thick blood smears of 500 participants of both sexes and age ranging from 1 to 79 years was conducted. Visual observations of clinical manifestations of chronic infection were also conducted. The overall prevalence and intensity of infection were 21% and 21.4 mf/mL of blood respectively. Microfilaraemic prevalence was significantly higher in males (27.1%) than in females (16%) (P < 0.001). However, intensity of infection was not gender and age dependent (P > 0.05). The overall prevalence of all clinical manifestations of infection due to W. bancrofti is 15% with hydrocele, limb and breast elephantiasis constituting 16.9%, 4.6% and 5.1% of the total population respectively. Prevalence of hydrocele and limb elephantiasis was significantly higher in the older age groups (P < 0.05). Occurrence of elephantiasis of the breast in women however was not associated with age (P > 0.05). Integrated approach through chemotherapy and vector control is therefore advocated to reduce morbidity due to infection in this study area. © 2013 Published by Elsevier Ltd.

Background & objectives: The study was aimed at elucidating the prevalence and intensity of Mansonella perstans microfilaraemia in the Emohua Local Government Area, Nigeria, and ascertaining the abundance, circadian, and the annual biting patterns of the Culicoides vector. Methods: Thick smear of 50 μl finger-prick blood stained with Giemsa was examined microscopically in a cross-sectional study. Vector landing collection on human bait was employed in a longitudinal study of the vector biting patterns, carried out between July 2005 and August 2006. Results: Of 1486 individuals examined, 11.2% of both males and females were positive for M. perstans microfilaraemia. Microfilaraemia appeared early in life. The overall geometric mean intensity among those with positive microfilaraemia was 117 mf/ml (121 mf/ml for males and 113 mf/ml for females). The differences in geometric mean intensity between different age groups were statistically significant (one-way analysis of variance; p <0.05), being highest in the oldest age group (266 mf/ml). A total of 1183 female Culicoides sp were caught from September 2005 to August 2006. The abundance of Culicoides sp was seasonal. The circadian biting activity had a broad peak between 0700 and 1200 hrs. The monthly biting rates ranged from zero bite per person per month in January 2006 to 1151 bites per person per month in June 2006. The annual biting rate was 7382 bites per person per year. Conclusion: Majority of those with positive microfilaraemia were poor socioeconomically, underscoring the need for health education and application of effective control measures against Culicoides biting midges in Emohua.
