Non-uniqueness of Hölder continuous solutions for Inhomogeneous Incompressible Euler flows
No full textWe consider the inhomogeneous (or density dependent) incompressible Euler equations in a three-dimensional periodic domain. We construct density and velocity such that, for any , both of them are -Hölder continuous and is a weak solution to the underlying equations. The proof is based on typical convex integration techniques using Mikado flows as building blocks. As a main novelty with respect to the related literature, our result produces a Hölder continuous density.41 pages. arXiv admin note: text overlap with arXiv:2006.06482, arXiv:2101.09278 by other author

Clinicopathological study of lesions of upper gastrointestinal tract
No full textConditions affecting the upper digestive system are often seen in clinical practice and are associated with a high rate of death and disability. Histopathological confirmation is one of the foundations for good treatment planning and the definite diagnosis of illnesses of the upper gastrointestinal tract. The numerous methods employed in the diagnosis of gastrointestinal lesions have come a long way in the previous 25 years. The identification and diagnosis of gastrointestinal lesions have been substantially aided by the development of endoscopy, endoscopic biopsy, and other surgical techniques. This research aimed to examine the variety of gastrointestinal tract (GI) lesions and to draw connections between the clinical and pathological manifestations of these conditions. Materials and Methods: A two-year cross-sectional study was conducted in the Department of Pathology, from June 2018 to May 2020, which included surgical specimens of 140 cases from the upper gastrointestinal tract, of which 111 cases were biopsy, and 29 cases were resected surgical specimens. The data were analyzed using SPSS software. Furthermore, P values, sensitivity, specificity, positive predictive value, and negative predictive value were calculated. Results: This study was a two-year cross-sectional study conducted in the Department of Pathology during the period of June 2018–May 2020

Unlocking Water's Potential for Energy Storage: Abundant Materials for a Ubiquitous Problem
No full textWater is an absolute necessity for life as we know it. It provides a useful medium in which chemical reactions take place that allowed for the development of single cellular organisms. When combined with the evolutionary accident that was pho- tosynthesis, water became not only a useful medium chemical reactions, but also a ready feedstock for the storage of chemical energy.
The potential to use water as the feedstock for energy storage is not simply of interest on the cellular level. One of the earliest popular references to the use of water for energy storage was by the 19th-century science fiction writer Jules Verne
in The Mysterious Island in 1874, and ever since then idea has tantalized scientists and engineers. The benefits of a energy system based on the conversion of water into a fuel and then back to water are self-evident and as a result the topic has been the focus considerable interest over the past 144 years. In that time, however, the energy required to produce hydrogen at the scale necessary has not been available.
The technologies required to enable the actual transition from a carbon-based energy dependence to a renewable energy system are only recently coming on-line. The greatest driver in this transition is the realization that continued reliance on fossil energy has placed us at the cusp of environmental catastrophe. This, in turn, has driven the development of renewable energy generation technologies. Gains in renewable energy capacity have exposed the inherent dissonance between when renewable energy is available and when energy in general in demand, in order to bridge that gap energy storage technologies need to be developed and deployed on a truly massive scale.
The scale of the energy storage problem necessitates strategies that utilize abun- dant materials for components of an energy storage system. This allows us to fall back on some microbial wisdom and refocus on water as an energy storage feedstock. Converting water into hydrogen and oxygen and then storing the hy-
drogen for later use as a fuel can be achieved by three means: thermochemical, photoelectrochemical, and electrochemical. The most technologically feasible and widely applicable method of hydrogen generation is via electrochemical means. Of the electrochemical devices for hydrogen production, the most efficient rely on the use of platinum group metals (PGM) as catalysts, adding significant cost to their manufacture and limiting the scale at which they can be deployed. This points to the need to develop non-PGM catalysts for use in water-splitting devices.
This dissertation focuses on two main subjects. First is the synthesis and physical characterization of first-row transition metal-based materials deposited in meso- porous substrates and their electrochemical performance as catalysts in water- splitting reactions. Second is the field’s current understanding of correlation be- tween the presence of iron and catalyst efficacy with the author’s own work demonstrating the superior performance of iron based catalysts. It is the hope of the author that reader will gain knowledge of the methods of deposition in porous carbon substrates and an understanding of electrochemical characterization of catalyst performance as it applies to water-splitting reactions

Nucleolin-Mediated RNA Localization Regulates Neuron Growth and Cycling Cell Size
No full textSummaryHow can cells sense their own size to coordinate biosynthesis and metabolism with their growth needs? We recently proposed a motor-dependent bidirectional transport mechanism for axon length and cell size sensing, but the nature of the motor-transported size signals remained elusive. Here, we show that motor-dependent mRNA localization regulates neuronal growth and cycling cell size. We found that the RNA-binding protein nucleolin is associated with importin β1 mRNA in axons. Perturbation of nucleolin association with kinesins reduces its levels in axons, with a concomitant reduction in axonal importin β1 mRNA and protein levels. Strikingly, subcellular sequestration of nucleolin or importin β1 enhances axonal growth and causes a subcellular shift in protein synthesis. Similar findings were obtained in fibroblasts. Thus, subcellular mRNA localization regulates size and growth in both neurons and cycling cells
Citation Pattern of the Nigerian Journal of Horticultural Science from 1990-2005
No full textIntroduction
The essence of academic journal publishing is to report research findings and to contribute to the field of knowledge. Journals are the most current channel of dissemination of new ideas, knowledge and breakthroughs in scientific development. Academic journals play a significant role in academic scholarship (Xiao and Smith, 2006). The present study therefore is undertaken on one of the renowned subject specialized academic journals, with the aim of analyzing citations cited in the various articles published therein.
Citation analysis examines bibliographic data from journal articles, monographs, published bibliographies, theses and electronic indexes in order to understand researchers\u27 specific information needs and explain trends in library use. Citations appearing in journals of particular disciplines provide an objective measure of the contributions of other knowledge systems to the development and progress of that particular discipline (Chandy and Williams, 1994). According to Gao , Yu, and Luo ( 2009) librarians have used several different quantitative methods to identify patrons\u27 needs, including circulation and shelving data, the analysis of interlibrary loan requests, as well as citation analysis.
Edward (1999) asserts that citation analysis can be used to determine a core collection of journals critical to local users and representative of the research needs of the collection. Gooden (2001) opines that citation analysis has been used by librarians in various disciplines to eliminate costly, low used/unused journals, purchase needed materials and ascertain core journals needed for patron use, and to reveal the most active research in a particular field. Ching and Chennupati (2002) opines that citation analysis is a form of checklist approach, and basically compares a library\u27s holdings to an authoritative list for the purpose of assessing the quality of all or part of the collection.
Furthermore, Gao et al, (2009) asserts that citation analysis has advantages over the other methods in a number of ways. Firstly, citing a publication may be the best indication of its importance since the citation implies that researchers read the publication and considered it important enough to include as a reference. Secondly, managing a citation study is relatively simple — it can be conducted by a single person. Thirdly, citation studies are reliable, valid, rapid, and economical and the data may be obtained unobtrusively. Fourthly, and perhaps most valuable for an academic librarian is the fact that a citation is a component of the most important product of the academic enterprise.
The Nigerian Journal of Horticultural Science was first published in May, 1990. It is published by the Horticultural Society of Nigeria. The Journal is the primary source for inquiry on horticultural crop production and sustainability in Sub-Saharan Africa; it is the key source of information that is consulted by researchers and scholars in horticultural research. Literature Review
Zhang (2007) analyzed research behavior of US international relations scholars by selecting peer-reviewed journals\u27 citations appearing in articles from the three leading international relations journals published from 2000 to 2005. His findings revealed that books and journals are the overwhelmingly dominant reference sources (86.6%), while the other formats are relatively less utilized in international relations research (13.5%). Kelsey and Diamond (2003) analyzed core journals in the interdisciplinary field of Forestry.
Similarly, Das and Sen (2001) analyzed 1049 citations appended to 34 research articles of Journal of Biosciences; 2000. It was found that out of the total citations, journal articles comprises 85.89% and monographs 10.1%. The report of Koley and Sen (2003) which covered 457 citations from 26 research articles published in the four issues of the quarterly Indian Journal of Physiology and Allied Sciences, also revealed that 76.81% related to journal articles, 18.59% to monographs, while others were conference papers and theses. Likewise the study of Javed and Shah (2008) revealed that 49.52 % citations pertained to journal articles and rest to other resource types. This shows that journals are heavily cited and preferred source of information. Journals are more cited than other literature sources because of the following: Currency of information, high rate of turnover of production, easy accessibility, frequency of production is faster than books and other primary sources.
Haycock (2004) analyzed 4542 citations from forty-three education dissertations completed at the University of Minnesota from 2000 to 2002. His research results were used to guide journal selection, retention, and cancellation decisions and to provide a basis for conversations with the faculty. Omekwu and Atinmo (1998) examined the author and journal citation patterns of Agricultural communication theses at the University of Ibadan. The result of the bibliographical reference of 37 theses studied showed a very significant difference in the citation of Nigerian and non-Nigerian authors, (with non-Nigerian authors cited more than Nigerian authors.) Dulle, F.W, Lwehabura, M. J. F, Matovelo, D.S, and Mulimila, R.T, (2004) analyzed citation pattern of Agricultural scientists in Tanzania, The study involved the analysis of 295 MSc theses and 21 PhD theses submitted at Sokoine University of Agriculture between 1989-1999, and 309 conference proceeding articles published during the same period. The result of the publications analysed, revealed that journals were more highly consulted(44.3% of the total citations), compared to other sources of literature (books-25.1%; proceedings-10.3%; theses- 4,2;% report-5.7% and other sources-10.4%).
Gao, et al. (2009) also analysed 56 PhD theses submitted in 2005 at Wuhan University in China. The authors analyzed 10,222 citations in theses in Library and Information Science, Biology, Photogrammetry and Remote Sensing, and Stomatology and reviewed and compared the characteristics of the literature cited in the four disciplines. Their results revealed an overwhelming emphasis on citations from the journal literature. Edwards (1999) analyzed 5874 citations of doctoral dissertations and masters thesis written at the University of Akron in the area of Polymer Science and Polymer Engineering from 1990 to 1996 to determine the characteristics of the materials being cited by graduate students.
Gooden (2001) studied 30 dissertations and generated a total of 3,704 citations. It was found that Journal articles were cited more frequently than monographs: 85.8% of the citations were journal articles and 8.4% of the citations were monographs
