Both control and experimental group were administered with the Attitude Towards Mathematics Inventory (ATMI) before the pretest were given and both group showed high dislike for Mathematics. Pretest showed a 53 percent accuracy for the control group and 51 percent for the experimental group using a 15-item long multiplication test without any aid of a computing device. The experimental group were taught how to use the Trachtenberg number-keys and techniques in multiplication between October 2014 to March 2015. Post-test showed an improvement in the experimental group with 96 percent accuracy for the control group and a dismal 57 percent for the control group in long-multiplication. Post-test ATMI were administered. The control group showed a great dislike towards Mathematics, while the experimental group showed a positive attitude towards the subject. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=attitude%20towards%20mathematics" title="attitude towards mathematics">attitude towards mathematics</a>, <a href="https://publications.waset.org/abstracts/search?q=mathematical%20competency" title=" mathematical competency"> mathematical competency</a>, <a href="https://publications.waset.org/abstracts/search?q=number-keys" title=" number-keys"> number-keys</a>, <a href="https://publications.waset.org/abstracts/search?q=trachtenberg%20speed%20math" title=" trachtenberg speed math"> trachtenberg speed math</a> </p> <a href="https://publications.waset.org/abstracts/34697/the-students-mathematical-competency-and-attitude-towards-mathematics-using-the-trachtenberg-speed-math-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34697.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3</span> Research of Concentratibility of Low Quality Bauxite Raw Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nadezhda%20Nikolaeva">Nadezhda Nikolaeva</a>, <a href="https://publications.waset.org/abstracts/search?q=Tatyana%20Alexandrova"> Tatyana Alexandrova</a>, <a href="https://publications.waset.org/abstracts/search?q=Alexandr%20Alexandrov"> Alexandr Alexandrov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Processing of high-silicon bauxite on the base of the traditional clinkering method is related to high power consumption and capital investments, which makes production of alumina from those ores non-competitive in terms of basic economic showings.

It sought to determine the relationships of educational philosophy and teaching styles of the college faculty vis-脿-vis the university system鈥檚 educational philosophies and teaching style preferences. A hundred and five faculty members from the Colleges of Education, Arts and Sciences responded to the survey during the academic year 2014-2015. The Philosophy of Adult Education Inventory measured the faculty鈥檚 preferred educational philosophies. The Principles of Adult Learning Scale measured the faculty鈥檚 teaching style preference. Findings show that there is a similarity between the university system and the faculty members in using the progressive educational philosophy, however both contrasted in the preferred teaching style. Majority of the faculty held progressive educational philosophy but their preference for teacher-centered teaching style did not match. This implies that the majority are certain of having progressive educational philosophy but are not utilizing the learner-centered teaching styles; a high degree of support and commitment to practice a progressive and humanist philosophical orientation in education; and a high degree of support on teacher-centered teaching style promotion from the institution can strengthen a high degree of commitment for the faculty to enunciate their values and practice through these educational philosophies and teaching styles. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=educational%20philosophies" title="educational philosophies">educational philosophies</a>, <a href="https://publications.waset.org/abstracts/search?q=teaching%20styles" title=" teaching styles"> teaching styles</a>, <a href="https://publications.waset.org/abstracts/search?q=philosophy%20of%20adult%20education%20inventory" title=" philosophy of adult education inventory"> philosophy of adult education inventory</a>, <a href="https://publications.waset.org/abstracts/search?q=principles%20of%20adult%20learning%20scale" title=" principles of adult learning scale"> principles of adult learning scale</a> </p> <a href="https://publications.waset.org/abstracts/34458/the-educational-philosophies-and-teaching-style-preferences-of-college-faculty-at-selected-universities-in-the-south-of-metro-manila" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34458.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">367</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">1</span> Morphological Process of Villi Detachment Assessed by Computer-Assisted 3D Reconstruction of Intestinal Crypt from Serial Ultrathin Sections of Rat Duodenum Mucosa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lise%20P.%20Lab%C3%A9jof">Lise P.

It was tested a morphological method of 3d reconstruction using micrographs of serial sections of rat duodenum. We used hundreds of sections of each specimen of duodenum placed on glass slides and examined under a light microscope. Those containing the detachment, approximately a dozen, were chosen for observation under a transmission electron microscope (TEM). Each of these sections was glued on a block of epon resin and recut into a hundred of 60 nm-thick sections. Ribbons of these ultrathin sections were distributed on a series of copper grids in the same order of appearance than during the process of microstomia. They were then stained by solutions of uranyl and lead salts and observed under a TEM. The sections were pictured and the electron micrographs showing signs of cells detachment were transferred into two softwares, ImageJ to align the cellular structures and Reconstruct to realize the 3d reconstruction. It has been detected epithelial cells that exhibited all signs of programmed cell death and localized at the villus-crypt junction. Their nucleus was irregular in shape with a condensed chromatin in clumps. Their cytoplasm was darker than that of neighboring cells, containing many swollen mitochondria. In some places of the sections, we could see intercellular spaces enlarged by the presence of shrunk cells which displayed a plasma membrane with an irregular shape in thermowell as if the cell interdigitations would distant from each other. The three-dimensional reconstruction of the crypts has allowed observe gradual loss of intercellular contacts of crypt cells in the longitudinal plan of the duodenal mucosa. In the transverse direction, there was a gradual increase of the intercellular space as if these cells moved away from one another. This observation allows assume that the gradual remoteness of the cells at the villus-crypt junction is the beginning of the mucosa detachment. Thus, the shrinking of cells due to apoptosis is the way that they detach from the mucosa and progressively the villi also. These results are in agreement with our initial hypothesis and thus have demonstrated that the villi become detached from the mucosa at the villus-crypt junction by the programmed cell death process. This type of loss of entire villus helps explain the rapid denudation of the intestinal mucosa in case of irradiation. <p class="card-text"><strong>Keywords:</strong> <a
