Experimental investigations on tetrahydrofuran – methane – water system: Rapid methane gas storage in hydrates
Authors: Sai Kiran Burla , Sowjanya Kandadai , Prasad Pinnelli S.R. , Yoon Ji-Ho 
Published: January 2019

This study reports methane (CH4) gas storage capacity along with TetraHydroFuran (THF) as guest molecules in mixed hydrates. This process has been studied in two reactors of 100 and 400 mL capacity, having 4.5 and 7.5 cm internal diameter respectively, in non-stirred configuration. Experiments were conducted in each reactor at constant initial gas pressure (7.5 MPa) and by increasing the height of the solution from 1 to 8 cm, resulting in volume scale-up factor of 5. The total CH4gas uptake (moles) passes through a maximum at around 50% volume of the reactor indicating a transition from gas-rich to solution rich conditions. Observed variations in gas uptake are within ±20% of the maximum, upon different solution volume from 35% to 70% of reactor’s volume. Another set of experiments were conducted keeping the amount of the solution constant and increasing gas pressure in the range of 0.5–11.0 MPa. The gas uptake increased upon an increase in the gas pressure, but this is at least 40% less compared to the theoretical estimate. The stirring of solution or addition of promoter (Sodium Dodecyl Sulfate, SDS) is also not effective in increasing the gas consumption. Kinetics of gas uptake, in both stirred and non-stirred conditions, are quicker and 90% of gas consumption occurs in an hour after the hydrate nucleation event.

CORRUPTION AND STOCK MARKET PERFORMANCE IN NIGERIA
Authors: Omodero Cordelia Onyinyechi 
Published: January 2019

AbstractThe study examines the effect of corruption (using corruption perception index and Nigeria corruption ranking as proxies) on the stock market performance (proxied with share price index) in Nigeria. The study employed time series data spanning twenty years (1996-2016). Data availability especially on corruption indices was the major reason underlying the choice of period. The data were obtained from CBN Statistical Bulletin and Transparency International website. With the aid of SPSS version 20, the study used Multi-regression analysis and student t-test for the test of hypotheses. The study finds a significant positive correlation between corruption and stock market performance in Nigeria. The result reveals robust positive and significant relationships between Nigeria Corruption Ranking, Corruption perception index and Share price index. The result of the study explains the integration of graft into the Nigerian economic system. Therefore, adoption of a strong form of stock market efficiency by the Security and Exchange Commission (SEC) and Nigerian Stock Exchange (NSE) for actualization by all listed firms in Nigeria is hereby recommended. In addition, we recommend that the Federal and State governments should formulate more result-oriented policies and rules that could help combat corruption more effectively.

Published: January 2019

Introduction. The authors arise the question of increasing the efficiency of the municipal machine. Moreover, the influence of the clamping force of the brush body on the surface and on the brush deterioration and, as a consequence, on the quality of the roadway cleaning is highlighted in the article.Methods and materials. The results of the changing process of the brushing tool vertical coordinate in the municipal machine were presented, depending on the displacement of the hydraulic cylinder rod. The analysis of the existing types of the brushing working body suspension was carried out. As a result of such analysis, the authors established the most frequent usage of the three-point and parallelogram suspensions, the schemes of which were also presented in the article.Results. The equations of geometrical connections of the municipal machine elements, which could be used in mathematical model, are presented. In addition, the kinematic diagram of the municipal machine with the brush working body suspension is drawn up. Therefore, the presented model takes into account such parameters as the length of the levers’ arms, the linear movements of the hinges, the rod stroke, the levers’ angles and the distances between the hinges. The methods and the course of the experiment for determining the displacement dependence of the brush body from the displacement of the hydraulic cylinder rod are described. The authors also present the photographs of the experimental research fragments.Discussion and conclusions. On the basis of the obtained data, the authors construct the experimental and theoretical dependences’ graph of the brush body displacement and the actuator hydraulic cylinder rod displacement. The analysis of such graphs confirms the adequacy of the geometric constraint equations and also proves that these equations could be used in the mathematical model of the position controlling process of the brush operating body and also for determination the optimum value of the brush working element clamping force to the surface.

Respecting Human Rights: Does Treaty Ratification Lead to Compliance?
Authors: St. Pierre Daniel 
Published: January 2019

Since the nonbinding Universal Declaration of Human Rights, states have created treaties and conventions to outline what is or is not acceptable regarding the treatment of human beings, with the understanding that if a state signs and ratifies these documents then that state will comply with the principles outlined within it. Time and again however, compliance, or the lack thereof, has presented as a concern amongst many states, as well as non-state actors. The issue of compliance is a serious one because it speaks to credibility. If states do not anticipate compliance from one another it undermines the entire international system and any structure that has been created to address the anarchic nature of international relations will dissolve. In order to make analysis of this massive issue area manageable, I focus on state compliance with human rights law and more specifically, compliance with the Indigenous and Tribal Peoples Convention 1989, or C169. Both Brazil and Argentina have signed and ratified C169 and both are democratic with indigenous populations. Comparing these two states it allows us to better ascertain the circumstances under which states may comply with or defect from international human rights law. I provide an overview on what rationalist theories suggest about compliance, followed by constructivist views. I then outline my position before examining the results of the case study and assessing its’ impact as related to both theory and my arguments. Ultimately, I find that notwithstanding ratification and well-developed democratic institutions that allow for a strong civil society to participate in politics, there are still circumstances wherein a state will defect from a human rights treaty because the gain of doing so outweighs the cost of non-compliance.
Determining a Relation between X-ray Luminosity and Orbital Period of X-ray Binaries
Authors: Naffin Tyler 
Published: January 2019

The goal of this project was to examine the relationship between the average x-ray luminosity and the orbital period of x-ray binaries. Using the data gathered by the All-Sky Monitor instrument aboard the Rossi X-ray Timing Explorer, 29 sources were selected for investigation based on the intensity of the x-rays emitted from each of the sources. A literature search was then performed to gather further details on each of the sources, including orbital period, distance, hydrogen column density, and classification of each source as either low- or high-mass x-ray binaries with either neutron star or black hole companions. Sufficient data for 22 of the sources was known in order to create plots of the average luminosity versus the period, which allowed for the period-luminosity relationships for x-ray binaries to be further examined.
Giant Steps In The Interpretation Of A Musical PDP Network
Authors: Hathaway Joshua , Dawson Michael R. W. 
Published: January 2019

We first introduce the notion of chord progressions by describing a particular example (the II-V-I) that is related to the Coltrane changes. Second, we describe the Coltrane changes using a formalism derived from previous musical investigations with neural networks (Yaremchuk & Dawson, 2005, 2008). Finally, we describe how we trained a neural network to generate the Coltrane changes, how we analyzed its internal structure, and the implications of this interpretation. In particular, we discovered that a network represented transitions between chords in a fashion that could be described in terms of a new musical formalism that we had not envisioned. In short, this paper shows that the interpretation of the internal structure of a musical network can provide new formalisms for representing musical regularities, and can suggest new directions for representational research on musical cognition.

Published: January 2019

Introduction: Pregnancy is a high risk factor not only for the mother but for the fetus as well. Certain oral changes especially bleeding gums, loosening of teeth, bad breath altered taste etc occurs secondary to factors like hormonal changes, lack of oral hygiene maintenance, diet, failure to visit dentist despite of having problems. Now a day along with that some other serious issues like low birth weight, pre-term labour, pre- eclampsia and certain oral infections have also been noticed. A study was conducted to evaluate the knowledge of pregnant patients regarding their oral health status, issues and the complications reported to the fetus so that necessary measures could be taken in addition to antenatal care for the health and benefit of mother and the fetus. Objectives: Assess the general and oral health status of expectant mothers along with their knowledge regarding the associated complications to fetus. Study Design: Random cross - sectional study design. Setting: Isra University Hospital. Period: August 2017 to January 2018. Methodology: A self-administered questionnaire was used to assess the general and oral health status of expectant mothers along with their knowledge regarding the associated complications to fetus. Collected data was statistically analysed by using spss version 17. Conclusion: This study provided an invaluable awareness regarding knowledge of pregnant females. Majority of them were poorly educated, did not know even about simple methods of oral hygiene maintenance, refused to visit dentists rather of having problems and above all were completely unaware about the possible risks and hazards to their baby secondary to oral health issues. Thus it was felt deemed necessary to aware and educate expectant mothers regarding routine oral checkup during antenatal period.

The present study aims to uncover how valid and reliable the multiple-choice test items as learning device are and their effect on permanent language habit formation. In this pretest-posttest one group pre-experiment study, we observed and analyzed the English test constructed by junior high school teachers. The Pretest on constructing the test items was administered to fifteen English teachers and some weaknesses were revealed. These can be seen from the total score of 855 and the mean score was 57.00. Treatment was given by ensuring them the rules of writing the test based on a principle of habit formation. The competence of teachers in constructing appropriate test items increased to higher quality indicated by scores of 79.33. It means the treatment has significantly influenced the ability of English teachers in constructing appropriate tests. The tests were tried out to 40 students of Junior High School and the result showed that 63 test items were valid and 37 was invalid. The fifty-valid test was administered to the students of different Junior High School and the result showed that the mean score was 72.53. 21 students from 40 students passed the minimum rank and 19 students still needed improving. The highest score was 95 and the lowest one was 26. The medium was 78 and the mode was 53. After measuring the reliability level, the standard deviation ranged 0.50 – 1.00, meaning that the test was appropriate to be applied as measuring device. The valid test was then reconstructed to be raw material of software module.

Validité de la FRENCH, l’échelle de tri des urgences hospitalières élaborée par la Société française de médecine d’urgence
Authors: Taboulet P. , Vincent-Cassy C. , Squara P.-A. , Resche-Rigon M. 
Published: January 2019

Introduction : La Société française de médecine d’urgence a créé en 2016 une échelle de tri pour les infirmier( ière)s d’accueil dans une structure d’urgences. Cette échelle appelée FRENCH (FRench Emergency Nurses Classification in Hospital) classe les tris de 5 à 1 (du moins urgent au plus urgent) en fonction du pronostic et de la complexité/ sévérité des motifs de recours aux soins. Le tri 3, groupe hétérogène dans les échelles de tri internationales, a été subdivisé en deux niveaux pour prioriser les patients qui ont une comorbidité en rapport avec le motif de recours aux soins ou qui sont adressés par un médecin et qui sont prioritaires (3A) par rapport aux autres patients (3B).
Objectif : Évaluer la pertinence de la FRENCH.
Méthode : Nous avons analysé les données démographiques, les paramètres vitaux, les examens complémentaires prescrits et les durées de prise en charge de tous les patients accueillis dans un hôpital universitaire sur une période de neuf mois consécutifs. Le critère de jugement était l’existence d’une relation croissante entre le niveau de complexité/ sévérité des patients — reflétée par le taux d’hospitalisation et la prescription d’examens complémentaires—et le niveau de priorité du tri.
Résultats : L’étude a inclus 27 598 patients. La répartition des patients par niveaux de tri était : 0,4 (tri 1), 6,7 (tri 2), 13,3 (tri 3A), 29,4 (tri 3B), 43,1 (tri 4) et 7,1 % (tri 5). Le taux d’hospitalisation était croissant quand l’ordre de priorité augmentait. La relation entre les niveaux de tri et le taux d’hospitalisation mesurée par l’aire sous la courbe (0,83 : intervalle de confiance à 95 % : [0,82–0,83]) était bonne. La prescription des examens complémentaires était croissante quand l’ordre de priorité augmentait. La corrélation entre les niveaux de tri et un indice global d’examens complémentaires prescrits était modérée (K = 0,51).
Conclusion : Cette étude monocentrique valide la pertinence de l’échelle de tri FRENCH à six niveaux par sa bonne capacité à classer les patients selon leur complexité/sévérité. De nouvelles évaluations sont nécessaires dans d’autres structures d’urgences pour confirmer sa performance et favoriser son évolution.
