An Assessment Of Public Library Services In North Eastern Nigeria, Adam Gambo Saleh, Fatima Ibrahim Lasisi

Library Philosophy and Practice (e-journal)

North Eastern Nigeria, formally one political state, is now made up of six autonomous states. Government efforts to coordinate library service in Nigeria as exemplified by the commissioning of two expert studies variously led by F. A. Sharr (1963) and R. L. Pearce (1968), were thwarted by the incessant political fragmentation of the Country into autonomous states, resulting in the emergence of inefficient and ineffective public libraries. With the achievement of political stability of some sort, in the last ten years as a result of the institutionalization of democracy, the question is has the situation changed? Are public libraries in …

Proceedings Of The Introduction To Neutrosophic Physics: Unmatter & Unparticle - International Conference, Florentin Smarandache

Branch Mathematics and Statistics Faculty and Staff Publications

Neutrosophic Physics.

Let A be a physical entity (i.e. concept, notion, object, space, field, idea, law, property, state, attribute, theorem, theory, etc.), antiA be the opposite of A, and neutA be their neutral (i.e. neither A nor antiA, but in between).

Neutrosophic Physics is a mixture of two or three of these entities A, antiA, and neutA that hold together.

Therefore, we can have neutrosophic fields, and neutrosophic objects, neutrosophic states, etc.

Paradoxist Physics.

Neutrosophic Physics is an extension of Paradoxist Physics, since Paradoxist Physics is a combination of physical contradictories A and antiA only that hold together, without …

Algebraic Structures Using Natural Class Of Intervals, Florentin Smarandache, W.B. Vasantha Kandasamy

Branch Mathematics and Statistics Faculty and Staff Publications

Authors in this book introduce a new class of intervals called the natural class of intervals, also known as the special class of intervals or as natural intervals. These intervals are built using increasing intervals, decreasing intervals and degenerate intervals. We say an interval [a, b] is an increasing interval if a < b for any a, b in the field of reals R. An interval [a, b] is a decreasing interval if a > b and the interval [a, b] is a degenerate interval if a = b for a, b in the field of reals R. The natural class of intervals consists of the collection of increasing intervals, decreasing intervals and the degenerate intervals. Clearly R is contained in the natural …

Interval Algebraic Bistructures, Florentin Smarandache, W.B. Vasantha Kandasamy

Branch Mathematics and Statistics Faculty and Staff Publications

Authors in this book construct interval bistructures using only interval groups, interval loops, interval semigroups and interval groupoids. Several results enjoyed by these interval bistructures are described. By this method, we obtain interval bistructures which are associative or non associative or quasi associative. The term quasi is used mainly in the interval bistructure B = B1 ∪ B2 (or in n-interval structure) if one of B1 (or B2) enjoys an algebraic property and the other does not enjoy that property (one section of interval structure satisfies an algebraic property and the remaining section does not satisfy that particular property). The …

Thermal, Electrical, And Structural Behavior Of Silver Chalcogenide Composites, Jeremy Capps

All Theses

In this thesis and the contained publications, it is demonstrated that it is not only possible to improve the dimensionless figure of merit (ZT) of silver chalcogenide composites, but it is also possible to move the maximum ZT value into a more favorable temperature range for power production. It is shown that by introducing disorder, stress, and phase competition into a system, a reduction in the material's thermal conductivity can be realized. The binaries Ag2Te and Ag2Se are re-examined in detail before moving on to examine Ag2Te1-xSex composites. The maximum ZT (ZT = 0.92) of Ag2Te0.5Se0.5 is measured at T= …

Physical Process Models As Regularization Constraints On Geophysical Imaging Problems, Rachel Grotheer

All Theses

Obtaining accurate images of solute plumes in the subsurface is important to understand site-specific subsurface flow and transport processes. Since image reconstruction is an inverse problem, its ill-posed nature makes obtaining an accurate, high-resolution image difficult. Further, current geophysical methods for plume imaging do not take into account models of the specific process being targeted for imaging.
The main objective of the research is to find a suitable basis that gives a sparse representation of the plume. In future work, we seek to use this basis as a physical constraint during the inversion so as to increase accuracy in imaging. …

Cloning, Expression Analysis, And Transformation Vector Construction Of Dam Homologs In Peach And Poplar, Yuhui Xie

All Theses

Genetic fine mapping and sequencing of the EVG locus in peach [Prunus persica (L.) Batsch] identified six tandem arrayed Dormancy-Associated MADS-box (DAM) genes as candidates for regulating growth cessation and terminal bud formation in the non-dormant evergrowing (evg) mutant. Since the mutant is lacking expression of six genes in the mapped locus, further functional analysis is needed to narrow the list of gene candidates for the non-dormant evg phenotype. Here I report three sets of experiments designed to functionally test DAM genes in peach and their homologs in a model tree, hybrid poplar.
First I constructed overexpression and knockdown vectors …

The Feasibility Of Using Bifidobacteria Bifidum (Atcc 700541) For The Production Of Prebiotic Oligosaccharides, Candice Marie Luehrs

Masters Theses

"Galactooligosaccharides (GOS) are prebiotics that are being used to influence intestinal microbiota towards health promoting, beneficial bacteria like bifidobacteria. Natural sources of GOS are not found in suitable levels to achieve the desired health effects so economically viable commercial production methods are important. Enzymatic conversion of lactose to GOS through transgalactosylation is a preferred method since the starting material is inexpensive and readily available. Enzymes used in batch production are purified from fungal or bacterial sources or remain in whole cells cultured for GOS production. Purified or unbound enzymes are single use whereas enzymes retained within whole cells can potentially …
