Development of Domestic Gas Supply Obligation Model for Efficient Gas Utilisation in Nigeria
Year: 2020

In the past government preferred to sell natural gas to international users rather than keep it for local utilisation. The possible explanation to this is that more revenue is accruable from the sale of the natural gas internationally than locally, and market instabilities further limits the choice of local supply of natural gas. This reason has led to scarcity of natural gas for local consumption leading to limited industrial progress because most industries utilise natural gas. To curb the situation, a method must be developed for proper allocation of natural gas domestically such that gas availability and assurance of local market is guaranteed. In this paper, a domestic gas supply obligation model is developed. The model was developed by determining mathematical equations relating the gas reserve, gas utilised, gas flared and gas demanded of a company. The model seeks to enhance optimum gas supply for allocation to the strategic sectors of the economy. The model is useful in mopping up gas from the gas producing multinationals and indigenous companies and redistributing it to the strategic users. The model works out the quota of gas quantities that primary producers should mandatorily supply to the national reserve. The work developed a monitory system that will persuade gas producers for compliance to the domestic gas supply obligation. The paper encouraged gas flare down management by ensuring that gases are adequately distributed and utilised locally. The model ensures that government do not lose out rightly by ensuring that each company supplies that quantity of gas it is obligated to.
Effect of Al and Cr addition on tribological behaviour of HVOF and APS nanostructured WC Co coatings
Year: 2007

Nanostructured WC Co based coatings were investigated. The main focus was given to the effect of Al and Cr addition on their tribological behaviour. These coatings were successfully deposited from engineered nanosized powders using high velocity oxy fuel (HVOF) and atmospheric plasma spraying (APS) Porosity level was <3% Crystal sizes of around 20 30 nm determined by TEM in such coatings, confirm the retention of a nanosize after thermal spraying. The nanostructured coatings were tested for their tribological characteristics and compared to industrial micrometre sized WC Co coatings and common wear resistant engineering materials. It was found that decarburisation of the coating constituents is a critical issue and has a large impact on the tribological behaviour of the coatings. Proper selection of spraying technique, spraying parameters and distribution of phases are shown to be key factors for achieving nanostructured coatings with high wear resistance.
Preliminary Validation of the Holistic Experience of Motivation Scale (HEMS) An Empirico Philosophical Approach Preliminarna validacija Skale cjelovito iskustvo motivacije: empirijsko filozofski pristup
Year: 2021

The aim of this study is to test the reliability and validity of the instrument known as Holistic Experience of Motivation Scale (HEMS) that has been used to examine the foundation of holistic experience of motivation in adolescents. Analyzing current research, theories, and practices in positive psychology, it is assumed that the need for purpose, i.e. recognition of the purpose, is a common need manifested differently in different constructs of human motivation. The HEMS is proposed after a theoretical and comparative analysis of various constructs of motivation, philosophies, and educational theories. Holistic Experience of Motivation (HEM) is measured in adolescents (age 14 15, total 50) after the intervention program (IP) in physical education that shows positive effects on intrinsic motivation, self determination, achievement of goals, flow, thriving, and mindfulness. In the preliminary validation of the instrument, reliability and validity were measured using descriptive and principal component factor analysis for the case 1:5 with the Monte Carlo method. In the final instrument of 10 variables, three preliminary factors emerged: purpose, focus and example/role model, but with the application of the Monte Carlo method only one factor emerged. The preliminary results show that the basis of the HEM can be the factor of "purpose" The purpose or meaning may be a common need that is presented through different constructs of motivation in positive psychology. Different philosophical paradigms and constructs of motivation are shown to be connected. It is shown that the purpose or meaning in question is of spiritual/religious nature and that it is manifested through satisfying the basic psychological needs of selfCroatian Journal of Education Vol.23; Sp.Ed.No.1/2021, pages: 11 30 Original research paper  May 2020  1 November 2020 https:/doi.org/10.15516/cje.v23i0.4032 Brankovic and Badric: Preliminary Validation of the Holistic Experience of Motivation Scale (HEMS) 12 determination and through the realization of motivational sparks that are markers of deep personal interests. The results show that the HEMS requires an upgrade with an additional validation on a larger sample and its correlation with other constructs in positive psychology. Also, they confirm that relationships have a significant role in motivation and recognition of personal purpose. The study presents the IP that can be used for making an environment for a holistic experience of motivation, which can also be applied in programs that aim toward the development of leadership and moral and ethical values in youth.

Wine Tasting: How Much Is the Contribution of the Olfaction?
Year: 2017

Neuromarketing predicts that multiple factors contribute to the choice of a product, among them, the perceived value, pleasantness, and emotion related to the use of it. In this framework, a particular field is constituted by luxury items, such as wine. Wine is particularly suitable to marketing effects, both extrinsic (label) and intrinsic features (volatile composition and color) lead to the constitution of the experienced value, and the analysis of the contribution of olfaction to the process of tasting is fundamental in order to study flavor perception. Scope of the present study was to investigate the reaction to the smell and the gustation of the wine, with and without the olfactory contribution, through an electroencephalographic index, assumed as an indicator of approach or withdrawal (AW) motivation, and an autonomic index (emotional index EI) deriving from the matching of heart rate and galvanic skin response activity. Results of this pilot research showed a statistically significant increase of the EI values in correspondence with wine smelling phase in comparison with the other two phases (p 0.01) and a trend of major avoidance attitude in correspondence with wine tasting with the olfactory component in comparison with the other two conditions. This result could be explained by the lack of specific subjects' expertise. Present data suggest a synergic action exerted by olfaction and gustation sensory modalities, where manipulation could be further studied so to investigate emotional and cognitive aspects of wine tasting experience.
Mathematical Critical Thinking and Creative Thinking Skills: How Does Their Relationship Influence Mathematical Achievement?
Venue: ICMSTTL 2019
Year: 2019

This paper examines the correlation of mathematical critical thinking and creative thinking skills towards students' mathematical achievements. A total of 115 eighth grade students from three schools in Sleman Regency were involved as the subject of this research. Data were obtained from the results of critical thinking skills test, the results of creative thinking skills test, and the results of mathematical achievement test on the learning material that students had studied in the previous semester. The instrument for testing critical thinking skills was the essay questions which measure the aspects of critical thinking skills, namely inference, analysis, evaluation, and interpretation, while the instrument for creative thinking skills test was also the essay questions which measure the aspects of creative thinking skills, namely originality, flexibility, and fluency. Besides, the data for the students' mathematical achievements were obtained from the report of mathematics achievement test prepared by the Mathematics Teachers' Working Group. The correlation of these variables was analyzed through multiple regression test. The analysis resulted a positive relationship between the mathematical critical thinking and creative thinking skills towards the mathematical achievement indicated by the regression coefficient R 0.721 and R2 0.52. These values showed that the influence of mathematical critical thinking and creative thinking skills on the students' mathematical achievements was 52% whereas 48% was influenced by other factors. Then, the coefficient value of creative thinking variable was b1 0.363 and the coefficient value of critical thinking variable was b2 0.477. These values indicated that if the creative thinking skill increases by one unit, the mathematical achievement increases by 0.363, on the other hand, if the critical thinking skill increases by one unit, the mathematical achievement increases by 0.477.
Poly(lactic acid)/cellulose nanocrystal composites via the Pickering emulsion approach: Rheological, thermal and mechanical properties.
Venue: International journal of biological macromolecules
Year: 2019

The use of nanocellulose is an attractive method to improve the characteristics of biodegradable polymers, but its effects are often affected by uneven dispersion. In this work, cellulose nanocrystals (CNCs) were evenly dispersed into poly(lactic acid) (PLA) via the Pickering emulsion approach. The PLA/CNC composites prepared were studied by rheological, thermal as well as mechanical measurements. Changes in the rheological characteristics of the composites showed that CNC promoted the transition of the composites from fluid to solid like behavior at high temperatures. The introduction of 5 wt% CNC improved the crystallinity of PLA considerably and increased the onset temperature of crystallization by about 10 degC. The storage modulus of the composites increased throughout the entire temperature range of testing. Flexural modulus was improved considerably. All the results indicated that the Pickering emulsion approach improves the dispersion of CNC in the PLA matrix and CNC improves efficiently most properties of PLA.
Deep Graph Library: Towards Efficient and Scalable Deep Learning on Graphs
Venue: ArXiv
Year: 2019

Accelerating research in the emerging field of deep graph learning requires new tools. Such systems should support graph as the core abstraction and take care to maintain both forward (i.e. supporting new research ideas) and backward (i.e. integration with existing components) compatibility. In this paper, we present Deep Graph Library (DGL) DGL enables arbitrary message handling and mutation operators, flexible propagation rules, and is framework agnostic so as to leverage high performance tensor, autograd operations, and other feature extraction modules already available in existing frameworks. DGL carefully handles the sparse and irregular graph structure, deals with graphs big and small which may change dynamically, fuses operations, and performs auto batching, all to take advantages of modern hardware. DGL has been tested on a variety of models, including but not limited to the popular Graph Neural Networks (GNN) and its variants, with promising speed, memory footprint and scalability.
The Role of Chest Imaging in Patient Management During the COVID 19 Pandemic
Venue: Chest
Year: 2020

With more than 900,000 confirmed cases worldwide and nearly 50,000 deaths during the first three months of 2020, the COVID 19 pandemic has emerged as an unprecedented healthcare crisis. The spread of COVID 19 has been heterogeneous, resulting in some regions having sporadic transmission and relatively few hospitalized patients with COVID 19 and others having community transmission that has led to overwhelming numbers of severe cases. For these regions, healthcare delivery has been disrupted and compromised by critical resource constraints in diagnostic testing, hospital beds, ventilators, and healthcare workers who have fallen ill to the virus exacerbated by shortages of personal protective equipment. While mild cases mimic common upper respiratory viral infections, respiratory dysfunction becomes the principal source of morbidity and mortality as the disease advances. Thoracic imaging with chest radiography (CXR) and computed tomography (CT) are key tools for pulmonary disease diagnosis and management, but their role in the management of COVID 19 has not been considered within the multivariable context of the severity of respiratory disease, pre test probability, risk factors for disease progression, and critical resource constraints. To address this deficit, a multidisciplinary panel comprised principally of radiologists and pulmonologists from 10 countries with experience managing COVID 19 patients across a spectrum of healthcare environments evaluated the utility of imaging within three scenarios representing varying risk factors, community conditions, and resource constraints. Fourteen key questions, corresponding to 11 decision points within the three scenarios and three additional clinical situations, were rated by the panel based upon the anticipated value of the information that thoracic imaging would be expected to provide. The results were aggregated, resulting in five main and three additional recommendations intended to guide medical practitioners in the use of CXR and CT in the management of COVID 19.
Use of a Mentored Creative Writing Project to Improve the Geology Education of Preservice Elementary Teachers
Year: 2006

The Earth Science Storybook Project is being conducted with Brigham Young University's (BYU) Physical Science 110B (PS 110B) class, which is introductory geology for Elementary Education majors. Under the project, preservice elementary teachers in PS 110B are mentored by university geology faculty and geology graduate students as they author children's storybooks in earth science. The storybooks are then illustrated and made available to practicing teachers for classroom use. This is done by an interdisciplinary collaborative effort between the BYU Geology Department and the BYU Visual Arts Department, which is providing senior illustration students to illustrate the storybooks at a relatively low cost. The goal is to use the mentored writing experience as a means of improving geology content knowledge for preservice elementary teachers and fostering their positive attitudes and self efficacy toward learning and teaching science. These goals are being assessed by (1) quantitative analysis of the PS 110B class exam scores of storybook authors versus a control group of PS 110B students in the same class who are not storybook authors; (2) a pre and post class Attitude Toward Science Survey; and (3) a geology teaching self efficacy instrument. The results of the project have been positive and indicate that when preservice teachers in a science class are given an opportunity to experience personal mentoring from the teaching faculty they do experience a shift toward a more positive attitude toward science.
Dynamical Systems in Neuroscience: The Geometry of Excitability and Bursting
Year: 2006

This book explains the relationship of electrophysiology, nonlinear dynamics, and the computational properties of neurons, with each concept presented in terms of both neuroscience and mathematics and illustrated using geometrical intuition. In order to model neuronal behavior or to interpret the results of modeling studies, neuroscientists must call upon methods of nonlinear dynamics. This book offers an introduction to nonlinear dynamical systems theory for researchers and graduate students in neuroscience. It also provides an overview of neuroscience for mathematicians who want to learn the basic facts of electrophysiology. "Dynamical Systems in Neuroscience" presents a systematic study of the relationship of electrophysiology, nonlinear dynamics, and computational properties of neurons. It emphasizes that information processing in the brain depends not only on the electrophysiological properties of neurons but also on their dynamical properties. The book introduces dynamical systems starting with one and two dimensional Hodgkin Huxley type models and continuing to a description of bursting systems. Each chapter proceeds from the simple to the complex, and provides sample problems at the end. The book explains all necessary mathematical concepts using geometrical intuition; it includes many figures and few equations, making it especially suitable for non mathematicians. Each concept is presented in terms of both neuroscience and mathematics, providing a link between the two disciplines. Nonlinear dynamical systems theory is at the core of computational neuroscience research, but it is not a standard part of the graduate neuroscience curriculum or taught by math or physics department in a way that is suitable for students of biology. This book offers neuroscience students and researchers a comprehensive account of concepts and methods increasingly used in computational neuroscience.
BUYER SUPPLIER COLLABORATION AND SUPPLY CHAIN RESILIENCE: A CASE STUDY IN THE PETROCHEMICAL INDUSTRY
Year: 2017

The purpose of this study was to investigate the underlying mechanisms through which buyer supplier collaboration enables resilience. A single case study method was adopted, examining a critical case within the petrochemical industry. Data was collected through semi structured interviews. The rationale for undertaking buyer supplier collaboration in the focal firm is grounded in Kraljic's procurement matrix, accounting for underlying risks of supply disruptions that are inherent in the resilience discourse. The findings suggested that collaboration between buyers and suppliers does not directly lead to supply chain resilience, but rather enables the antecedents to supply chain resilience. The study developed an understanding of the specific mechanisms through which the antecedents of resilience are enabled in the petrochemical industry.
Effect of Pulsed Light Irradiation on Bioactive, Nonvolatile Components and Antioxidant Properties of Caterpillar Medicinal Mushroom Cordyceps militaris (Ascomycetes)
Venue: International journal of medicinal mushrooms
Year: 2017

The caterpillar medicinal mushroom Cordyceps militaris contains many bioactive components, such as adenosine, cordycepin, and polysaccharides. In this study, C. militaris was exposed to 0, 3, 6, or 9 pulses of light irradiation to estimate changes in vitamin D2, bioactive compounds, nonvolatile taste components, and antioxidant properties. In addition, we compared the components and properties of C. militaris mycelia and solid waste medium that had been treated with pulsed light (PL) irradiation. Overall, PL irradiation of C. militaris increased the vitamin D2 content and increased the total amino acid levels 9 48% the antioxidant properties of the mycelia treated with 0 pulses and of the solid waste medium treated with 3 pulses all exhibited lower half maximal effective concentrations. Therefore, PL irradiation affected the amounts of bioactive compounds, but the irradiated samples still contained intense umami taste and a sufficient amount of antioxidant components.
AN INVESTIGATION OF AMERICAN OPPOSING POLITICAL CULTURES IN THE SPEECHES OF BARACK OBAMA AND JOHN MCCAIN
Year: 2016

American political discourse in line with Lakoff's (1996) interpretation of American political reality. According to Lakoff, Republican and Democratic political thought is guided by two opposing value systems. Against this background, the current study examines elements of McCain's and Obama's speeches during their presidential election campaign in 2008. The analysis explores how highly frequent lexical items characterizing the rhetoric of the Republican and the Democratic candidates can be indicative of distinctive ideologies that affirm the existence of two contending political cultures. As such, the paper proposes an investigation of political discourse across two different political cultures in the context of the US.

Year: 2020

In this paper, we build the Wong Zakai approximation for Stratonovich type stochastic differential equations driven by G Brownian motion and obtain the quasi sure convergence rate under Holder norm by a rough path argument. As a corollary, we obtain the quasi continuity of solutions of random rough differential equations driven by lifted martingales under a sequence of singular measures.
Diseno y desarrollo de una aplicacion movil educativa basada en juegos
Year: 2019

Primary education is one of the most important educational stages of life, in many cases there are not enough tools available to favor a good learning environment for children. The purpose of this project is an application development for those children who make a change of school and are faced with the need to review the destination school temary, since there is often a difference in level between same courses of different schools, which can be a serious obstacle for the student. Nowadays the solution to these situations is usually to make a review through a summer book to reach the level that is intended, but this does not always work. This application is based on the idea of game based learning and gamification, the student must always be motivated to learn and improve their level in the various subjects, which in turn favors his school performance. Everything must be done with the support of family members and teachers, who at any time can know the performance of the student with the application. In the development, the spiral model methodology is used to develop an application that is as useful as possible with the collaboration of end users.
