The population of the study comprised all 48 final year students in the LIS unit of the departments of Educational Technology and Library Science, University of Uyo and the students were purposively sampled for the study. A structured questionnaire and a checklist constituted the instruments for data collection. The data obtained were analyzed using Mean and Standard Deviation to answer research questions while t-test, Analysis of Variance and Simple Regression Analysis were used to test the hypotheses at 0.05 level of significant. The result revealed that there is a significant influence of availability and functionality on the use of ICT facilities in teaching LIS courses in the University of Uyo library school and concluded that the availability and functionality of ICT facilities enhance usage for the teaching of LIS students. It also recommended proper funding of library schools. Keywords: ICT facilities, functionality, utilization, library and information science, students, uy

Awareness and Digitization of School Library Resources in Akwa Ibom State, Nigeria

This study investigates the awareness and digitization of school libraries in Akwa Ibom State. The main objective of the study was to examine the extent of awareness of librarians on digitization of school library resources in private secondary schools and the software used in digitization and to further examine if the school librarians have the necessary skills for digitization of the library resources in Akwa Ibom State. Out of about 150 private secondary schools in the state, 25 were randomly sampled for the study. This study adopts cognitive flexibility theory. The design for the study was descriptive survey. The data were analysed using percentages and charts. The result of the findings indicated that librarians in Akwa Ibom State school libraries are awareof the digitization technology; but the extent of planning for digitization is low in their libraries. It was noticed that there are inadequate facilities in the libraries for digitization. The study further revealed that the school librarians do not have the skills for the implementation of digitization in the school libraries. Among the recommendations made was that school librarians should be trained and retrained for information skills acquisitio

Survey of drug use and crime in Nigerian libraries: a study of public and academic libraries in Akwa Ibom state.

Drug use is a menacing problem currently affecting every aspect of Nigeria's national life. The clandestine nature of many drug use behaviours-may provide suitable conditions for the development of relative ethnographies, and one of such is the library environment as a secret hideout for drug abuse. Considering the seclusive nature of every library complex, the present study investigated, through a survey, the possible existence and prevalence of drug use network in selected public libraries in Akwa Ibom State, Nigeria. Participants were library users and patrons, including students, library workers and other public users. Results indicate that negligible (low) level of drug use was reported in the library with corresponding low level of related crime. There were also other indicators of drug use comparing respondents‟ reports under several demographic factors including gender, education, marital status of users, residential status of users, recent history of drug use in the library, estimated age of users, estimated financial cost of drug use as well as indices of crimes committed in the library. It was however not clear if reported crimes, which are usual day to day occurrences associated with the library, could in any way be linked to library drug use. Recommendations were made concerning the need and urgency to provide public sensitization on the dangers of drug use not only in the library but also in general, and the need to prevent its consequences through improved security measures in our academic and public facilities.

Rapid Thermal Technologies for High Efficiency Silicon Solar Cells

Presented at the 12th International Photovoltaic Science and Engineering Conference; Jeju Island, Korea; June 11-15, 2001.This paper shows that rapidly formed emitters (≤ 6 min) in a conveyor belt furnace or 3 minutes in an RTP system, in conjunction with a screen-printed (SP) RTP Al-BSF and passivating oxide formed simultaneously in 2 minutes can produce high efficiency cells with no surface texturing, point contacts, or selective emitter. It is shown for the first time that an 80 Ω/ emitter and SP Al-BSF formed in a high throughput belt furnace can produce 19% FZ cells, 18.4% MCZ cells and greater than 17% CZ cells with photolithography (PL) contacts. Using PL contacts, we also achieved 19% efficient cells on FZ, >18% on MCZ, and ~17% boron-doped CZ by emitter and SP Al-BSF formation in less than 10 minutes in a single wafer RTP system. Finally, a manufacturable process with 45 Ω/ emitter and screen-printed (SP) Al-BSF and Ag contacts formed in the conveyor belt furnace gave 17% efficient cells on FZ silicon. Compared to the photolithography cells, the SP cell gave ∼2% lower efficiency along with a decrease in Jsc and fill factor (FF). This loss in performance is attributed to a combination of the poor blue response, higher series resistance and higher contact shading in the SP devices

Ecological niche modelling of Hemipteran insects in Cameroon ; the paradox of a vector-borne transmission for Mycobacterium ulcerans, the causative agent of Buruli ulcer

Background: The mode of transmission of the emerging neglected disease Buruli ulcer is unknown. Several potential transmission pathways have been proposed, such as amoebae, or transmission through food webs. Several lines of evidence have suggested that biting aquatic insects, Naucoridae and Belostomatidae, may act as vectors, however this proposal remains controversial. Materials and methods: Herein, based on sampling in Cameroon, we construct an ecological niche model of these insects to describe their spatial distribution. We predict their distribution across West Africa, describe important environmental drivers of their abundance, and examine the correlation between their abundance and Buruli ulcer prevalence in the context of the Bradford-Hill guidelines. Results: We find a significant positive correlation between the abundance of the insects and the prevalence of Buruli ulcer. This correlation changes in space and time, it is significant in one Camerounese study region in (Akonolinga) and not other (Bankim). We discuss notable environmental differences between these regions. Conclusion: We interpret the presence of, and change in, this correlation as evidence (though not proof) that these insects may be locally important in the environmental persistence, or transmission, of Mycobacterium. ulcerans. This is consistent with the idea of M. ulcerans as a pathogen transmitted by multiple modes of infection, the importance of any one pathway changing from region to region, depending on the local environmental conditions

Relationship between age at menopause, obesity, and incident heart failure: The Atherosclerosis Risk in Communities Study

Background The mechanisms linking menopausal age and heart failure (HF) incidence are controversial. We investigated for heterogeneity by obesity on the relationship between menopausal age and HF incidence. Methods and Results Using postmenopausal women who attended the Atherosclerosis Risk in Communities Study Visit 4, we estimated hazard ratios of incident HF associated with menopausal age using Cox proportional hazards models, testing for effect modification by obesity and adjusting for HF risk factors. Women were categorized by menopausal age: \u3c45 years, 45 to 49 years, 50 to 54 years, and ≥55 years. Among 4441 postmenopausal women, aged 63.5±5.5 years, there were 903 incident HF events over a mean follow-up of 16.5 years. The attributable risk of generalized and central obesity for HF incidence was greatest among women who experienced menopause at age ≥55 years: 11.09/1000 person-years and 7.38/1000 person-years, respectively. There were significant interactions of menopausal age with body mass index and waist circumference for HF incidence
