Bicontinuous cubic liquid crystalline phase nanoparticles stabilized by softwood hemicellulose
No full textThe colloidal stability of lipid based cubosomes, aqueous dispersion of inverse bicontinuous cubic phase, can be significantly increased by a stabilizer. The most commonly used stabilizers are non-ionic tri-block copolymers, poloxamers, which adsorb at the lipid-water interface and hence sterically stabilize the dispersion. One of the challenges with these synthetic polymers is the effect on the internal structure of the cubosomes and the potential toxicity when these nanoparticles are applied as nanomedicine platforms. The natural polysaccharide, softwood hemicellulose, has been proved to be an excellent stabilizer for oil-in-water emulsions, partially due to the presence of hydrophobic lignin in the extract which to some extent is associated to hemicellulose. Herein, we reported for the first time cubosomes stabilized by two types of softwood hemicelluloses, where one is extracted through thermomechanical pulping (TMP, low lignin content) and the other obtained from sodium-based sulfite liquor (SSL, high lignin content). The effect of the two hemicellulose samples on the colloidal stability and structure of monoolein-based cubosomes have been investigated via DLS, SAXS, AFM and cryo-TEM. The data obtained suggest that both types of the hemicelluloses stabilize monoolein (GMO) based cubosomes in water without significantly affecting their size, morphology and inner structure. SSL-extracted hemicellulose yields the most stable cubosomes, likely due to the higher content of lignin in comparison to TMP-stabilized ones. In addition, the stability of these particles was tested under physiological conditions relevant to possible application as drug carriers

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Некоторые трибологические свойства Al-W-B материалов
No full textОбъектом исследования являются технологические отходы при производстве композитного материала Al-W-B, содержащего однонаправленные иглообразные боровольфрамовые волокна и алюминиевую матрицу. Потенциальные возможности применения отходов Al-W-B материала должны быть обоснованы их соответствующими свойствами.
Особый интерес представляют отходы этих материалов после их измельчения в порошок Предполагается их использование в качестве лигатуры при изготовлении некоторых сплавов. а также в качестве материалов для шлифовально – полировального инструмента. Однако пока отсутствуют данные по исследованию трибологических и абразивных свойств Al-W-B материалов. Этому направлению и посвящена данная работа
The Motivation of Academic Achievement and its Relationship With The (A-B) personality Patterns Among The Students of Al-Quds University
No full textThe study aimed to identify the motivation of academic achievement and its relationship with the two patterns of personality (A-B) among the students of Al-Quds University and to discover the motivation level of academic achievement , in addition to know the personality pattern (A-B) which is prevailing among the students of Al-Quds University, and to know the differences in the level of motivation of academic achievement and the level of the personality patterns (A-B) among the students of Al-Quds University according to the variables of ( social gender, faculty, accumulative average, place of residence, birth order). In order to achieve the aims of the study, the descriptive correlational methodology was used. The sample of the study was chosen by the random stratified way. The sample of the study consisted of (399) male and female students. The researcher used the measure of academic achievement which was prepared by (Al-Umari,2012) and the measure of personality patterns which was prepared by (Ghawanmenh,2012). The validity and reliability of the two instruments of the study were verified.
The results of the study revealed the following: There is a direct relationship between the motivation of academic achievement and the two personality patterns of (A-B) among the students of Al-Quds University. The level of motivation of academic achievement among the students of Al-Quds University came at a medium degree, also the results revealed that students from the personality pattern (A) have high motivation of academic achievement , and that students from the personality pattern (B) have medium motivation
و
of academic achievement. The prevailing personality pattern among the students of Al-Quds University is the pattern (A). There were no differences in the level of motivation of academic achievement among the students of Al-Quds University which are due to the variable of social gender, the variable of the faculty, and the variable of birth order. It was indicated that there are differences due to the variable of the place of residence in favor of the inhabitants of the camps, and to the variable of the accumulative average, in favor of those whose average is (86% and more ) . There were no differences in the level of personality pattern (B) among the students of Al -Quds University which are due to the variable of social gender, and the variable of the faculty, while there were differences among the personality pattern (B) which are due to the variable of social gender. The differences were in favor of the females. There were differences among the students having the personality pattern (A) due to the variable of the faculty. The differences were in favor of the scientific faculties. It was also indicated that there were no differences in the level of the two personality patterns (A-B) which are due to the variable of the place of residence. The results also indicated that there were no differences for the pattern (B) which are due to the variable of birth order and to the variable of the accumulative average, while there were differences for the personality pattern (A), and they were in favor of the first birth order, and to the variable of the cumulative average for the (A) pattern, and they were in favor of the averages from( 76% - 85%). In the light of these results, the researcher recommended: It is necessary that the educational institutions take interest, increase the efforts, offer psychological and social guidance to the students of the Palestinian universities, and lessen the psychological pressure to which the students are exposed. Benefiting from the students who have the (A) personality pattern in the competitive university activities
