Bibliographic Control of Publications: The Impact on African Countries

The African continent is full of oral and written culture being published and preserved by her people, not only for posterity but also for academics, students, and the larger bibliographic communities. That information is generated on the face of African continent on daily bases is not in doubt as printing and publishing have flourished the continent, thus becoming the order of the day. Libraries and information centers are expected to acquire and ensure bibliographic recording and make available on request all that is written, printed and published. Bibliographic control has become a major determinant of book accessibility and utilization and a key factor in information search, delivery and dissemination. The bibliographic control project is very important, fundamental, and indispensable in Africa. Fourie and Burger (2007) have observed that countries like South Africa have put forward efforts currently unmatchable by any African country. The fact that a book is recorded in the library, internet, or the information centre is enough to give hope to the needful potential user that it may be possible to access and use it. Information materials like books, journals, manuscripts, theses, dissertations, magazines, newspapers and a host of others are written, printed, and published on African continent. As time goes on, precise bibliographic information about these materials begin to disappear from the minds of many but on the other hand, some researchers may seek them with tears to access and utilize them; thus, the importance of bibliographic control and that of the library services become glaringly indispensable. To facilitate accessibility, the bibliographic compilation must be in a particular pertain which must be systematic to accommodate essential bibliographic elements which could enable a potential user to decide to trace it when in need. This calls for a pattern of effective recording and arrangement which result from systematic listing of the records of human communication. One current type of bibliography, according to World Book Encyclopedia (2002) presents a systematic description of books as well as listing them, summarizing what each book is about as well as its currency, binding, publisher and its value

Integrated Geologic and Geophysical Assessment of the Eileen Gas Hydrate Accumulation, North Slope, Alaska

Using detailed analysis and interpretation of 2-D and 3-D seismic data, along with modeling and correlation of specially processed log data, a viable methodology has been developed for identifying sub-permafrost gas hydrate prospects within the Gas Hydrate Stability Zone (HSZ) and associated ''sub-hydrate'' free gas prospects in the Milne Point area of northern Alaska (Figure 1). The seismic data, in conjunction with modeling results from a related study, was used to characterize the conditions under which gas hydrate prospects can be delineated using conventional seismic data, and to analyze reservoir fluid properties. Monte Carlo style gas hydrate volumetric estimates using Crystal Ball{trademark} software to estimate expected in-place reserves shows that the identified prospects have considerable potential as gas resources. Future exploratory drilling in the Milne Point area should provide answers about the producibility of these shallow gas hydrates

Robust estimation of bacterial cell count from optical density

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data
