Pitfalls in Cytodiagnosis of Pleomorphic Adenoma of the Nasal Septum - A Rare Case Report
Abhishek MG,Vijayshankar S,Amitha Krishnappa
Online Journal of Health & Allied Sciences , 2010,
Abstract: Pleomorphic adenoma is the most common benign mixed tumor of major salivary gland. Ectopic occurrence of pleomorphic adenoma are seen in minor salivary glands of pharynx, trachea, larynx and very rarely in nasal septum. We report a case of 40 year old female who presented with right sided nasal mass and mild nasal obstruction since six months. Cytologically a possibility of pleomorphic adenoma was made which was confirmed by histopathological study. We present this case due to 1) rarity in the nasal septum 2) pitfalls at cytology due to abundance (predominance) of myoepithelial cells and scanty or even absent mesenchymal component and 3) under reporting in English literature to the best of our knowledge.

Online Journal of Health & Allied Sciences , 2010,
Abstract: Primary cutaneous mucinous adenocarcinoma is a rare adnexal neoplasm, eyelid being the most common site of presentation. Clinically it is mistaken for a benign / cystic lesion. Its morphologic similarity to metastatic deposits from breast, gastrointestinal tract (GIT) or any visceral sites adds to the diagnostic difficulty mandating the role of ancillary techniques in precise diagnosis and hence planning the management. We report a case of primary cutaneous mucinous adenocarcinoma of eyelid with emphasis on pathology along with a brief review of literature.

Smart Grid and Renewable Energy (SGRE) , 2012, DOI: 10.4236/sgre.2012.33024
Abstract: Integration of unpredictable renewable power sources into the Grid is leading to the development of wide area control algorithms and smart grid. Smart meters are the first step in the building a smart consumer interface. Much more, however, would be required in building a smart grid than just smart meters. This paper explores the conceptual architecture of smart grid. It highlights the need for additional infrastructure to realize full potential of smart grid. The information presented in this paper is an attempt to uncover what the future in smart grid could be and what infrastructure would be required to tap its potential. As smart grid evolves, more functionality would be built in the constituents. The paper also proposes mathematical basis for some of the controller algorithms.

Social Networking (SN) , 2015, DOI: 10.4236/sn.2015.43007
Abstract: Data collection represents the most effort-intensive stage of any marketing research exercise, especially in cases sampling frame is unavailable. Sub-optimal bypasses in form of student surveys or surveys employing convenience sampling have become common. In modern era, where laptops and smartphones enable easy accessibility of respondents online, this study utilizes Facebook advertisement as a source of data collection to measure the construct of user experience for interactive products. Modern digital devices, like smartphones, are a source of a variety of experiences for the user. Design teams at various smartphone manufacturers are struggling every day to create products which provide complete consumer experiences. This work not only proposes a framework for describing the same with usability, social value and pleasure in use, but also tests the scales for each by empirical validation. Data collection process through Facebook, as a sample frame, is something yet to be seen in marketing literature. This work goes the distance in not only demonstrating the efficacy of using Facebook advertisement as a viable data collection tool but also developing a framework to measure consumption value. Outcomes of the study, should promote further research using this sampling frame for future research, especially in the area of marketing.

MG Taura
Bayero Journal of Pure and Applied Sciences , 2011,
Abstract: Anthropometry is a branch of anthropology that deals with the measurements of various parts of human body which are expected to grow predictably and proportionately. The aim of this work was to study some of the anthropometric parameters of the Hausa people residing in Kano, northwestern Nigeria. Anthropometric parameters measured and recorded in this study were height, weight, body mass index and blood pressure. The measurements were made according to the standard procedures. Sample size of 1113 subjects comprising of 599 (53.8%) males and 504 (46.2%) females were used for the study. The age range of the subjects was 18 to 60 years with mean age of 23.2 years. Instruments used included weighing machine, stadiometer, and blood pressure apparatus. The results showed that all values were higher in males than females except for body mass index which was higher in female subjects. Bivariate analysis showed a positive correlation between the parameters except for height and body mass index where a negative correlation was observed. The values of the anthropometric parameters in this study were similar to those of other Nigerian ethnic groups and tribes. The values also correlate with the findings from other countries. It is concluded from the findings of this study that the anthropometric parameters and blood pressure of the Hausas of northern Nigeria are within acceptable reference range.

Journal of Agricultural Extension , 2011,
Abstract: The paper examined the influence of Socio economic variables on dry season fluted pumpkin production in Njikoka Local Government Area of Anambra State, Nigeria. A multi-stage sampling technique was used to select the respondents for the study. Primary data was collected by means of structured questionnaire and 3- point liket scale. Nonparametric and parametric statistical tools including frequency distribution, percentages, means, mean ranking and multiple regression analysis were deployed for the data analysis. Majority (45%) of the farmers were aged 51-60 years and 95% were females. The result revealed that 47.50% of the respondents earned N76, 000. and above, indicating poverty level slightly above the benchmark of one U.S dollar per day. The multiple regression analysis showed that income of the farmers was significantly influenced by educational level, fertilizer application and access to credit at 5% level of significance. The paper revealed the constraints of the farmers to include insufficient land, lack of credit, high cost of labour, high cost of farm inputs among others. The result also showed a dearth in extension delivery system, especially in the dissemination of useful and technical information and procurement of improved yield increasing agricultural technologies to farmers. This suggests the need for intensified efforts of extension in the areas of seminars, workshops, meetings, conferences etc for farmers. Finally, government should subsidize improved agricultural inputs to enable the farmers compete favourably with the recent challenges in agricultural production.

Abstract: Recent changes in the social and economic conditions of many nations of the world have led to the on-going special attention being focused on the role of rural women in development. As a result of these strategies, the research was initiated to study the analysis of services provided by Village Alive Women Association (VAWA) for the rural women in Ifelodun Local Government Area of Kwara State. This study focus on demographic characteristics of the beneficiaries, services provided by VAWA, attitude of rural women towards the VAWA services, level of participation of rural women, constraints facing the rural women and the benefit derived by rural women from the VAWA services. Information required for this study was obtained through the use of interview schedule which include open and close ended questions. Four villages were selected one of which 102 respondents (10% of the whole population) were randomly chosen to form the sample for the study, the result indicated that most of the respondents are young adult women between the ages of 18 – 30 years. Most of them had no formal education. The findings using Chi-square and Correlation analysis showed that stenographic characteristics of the respondents are significant with the services of VAWA to the rural women. It was confirmed that the respondents have a favourable attitude, level of participation, constraints and benefit derived towards VAWA services and they are more willing to continue with the activities of VAWA. In view of the above, the study recommended that money and other necessary technologies should be made available to the hardworking Rural women of Nigeria by different NGOs and Voluntary organizations so that they can increase their productivity those government organs or agencies (ADP, MANR, NCAM) set up to ameliorate the hardship of rural women should realize their potentialities ad come to their aid with incentives. Further research shall be conducted to look at the analysis of each of the VAWA services and the impact of governmental and non-governmental organizations assistance to income generating activities of women in the rural areas.

Abstract: archically nanostructured hydroxyapatite: hydrothermal synthesis, morphology control, growth mechanism, and biological activity Original Research (3600) Total Article Views Authors: Ma MG Published Date April 2012 Volume 2012:7 Pages 1781 - 1791 DOI: http://dx.doi.org/10.2147/IJN.S29884 Received: 12 January 2012 Accepted: 02 February 2012 Published: 03 April 2012 Ming-Guo Ma Institute of Biomass Chemistry and Technology, College of Materials Science and Technology, Beijing Forestry University, Beijing, People's Republic of China Abstract: Hierarchically nanosized hydroxyapatite (HA) with flower-like structure assembled from nanosheets consisting of nanorod building blocks was successfully synthesized by using CaCl2, NaH2PO4, and potassium sodium tartrate via a hydrothermal method at 200°C for 24 hours. The effects of heating time and heating temperature on the products were investigated. As a chelating ligand and template molecule, the potassium sodium tartrate plays a key role in the formation of hierarchically nanostructured HA. On the basis of experimental results, a possible mechanism based on soft-template and self-assembly was proposed for the formation and growth of the hierarchically nanostructured HA. Cytotoxicity experiments indicated that the hierarchically nanostructured HA had good biocompatibility. It was shown by in-vitro experiments that mesenchymal stem cells could attach to the hierarchically nanostructured HA after being cultured for 48 hours. Objective: The purpose of this study was to develop facile and effective methods for the synthesis of novel hydroxyapatite (HA) with hierarchical nanostructures assembled from independent and discrete nanobuilding blocks. Methods: A simple hydrothermal approach was applied to synthesize HA by using CaCl2, NaH2PO4, and potassium sodium tartrate at 200°C for 24 hours. The cell cytotoxicity of the hierarchically nanostructured HA was tested by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. Results: HA displayed the flower-like structure assembled from nanosheets consisting of nanorod building blocks. The potassium sodium tartrate was used as a chelating ligand, inducing the formation and self-assembly of HA nanorods. The heating time and heating temperature influenced the aggregation and morphology of HA. The cell viability did not decrease with the increasing concentration of hierarchically nanostructured HA added. Conclusion: A novel, simple and reliable hydrothermal route had been developed for the synthesis of hierarchically nanosized HA with flower-like structure assembled from nanosheets consisting of nanorod building blocks. The HA with the hierarchical nanostructure was formed via a soft-template assisted self-assembly mechanism. The hierarchically nanostructured HA has a good biocompatibility and essentially no in-vitro cytotoxicity.
Exploring safety in township secondary schools in the Free State province

South African Journal of Education , 2011,
Abstract: Research overwhelmingly suggests that effective teaching and learning can occur only in a safe and secure school environment. However, despite the plethora of laws and acts protecting teachers and learners in South African schools, scores of them are still unsafe. This study examines the safety of teachers and learners in township secondary schools in the Free State province, South Africa. The sample of study consisted of 396 teachers who were randomly selected from 44 township secondary schools across the province. The sample completed a questionnaire based on the safety of teachers and learners in their schools. Prior to completion, the questionnaire was tested for reliability using the Cronbach alpha coefficient and it was found to have a reliability score of .885, indicating an acceptable reliability coefficient. The questionnaire was computer analysed using the Statistical Package for Social Sciences Primer Version 12. The results of the analysis revealed that both teachers and learners are not safe in their schools, either during or after school hours. The causes of a lack of safety in these schools reside within and without the schools, implying that learners are sometimes the culprits. The study concludes with recommendations on addressing the problem.
