Published: November 2019

A carbon footprint is the number of greenhouse gases released into the atmosphere by particular human activity. Usually, a carbon footprint is calculated for a year. This study plans to evaluate the carbon footprint of the university. The Greenhouse Gas (GHG) Protocol Corporate Standard for developing a GHG inventory in a university will be used as a standard and guideline. A university has to determine its organizational boundaries in terms of the operations in identifying emissions associated with its services, categorizing them as direct and indirect emissions, and choosing the scope of accounting and reporting for indirect emissions. The primary sources of carbon footprint in the university are from goods and services, transportation, and energy production. This study will document carbon footprint assessment strategies adopted by higher education institutions in the Universiti Teknologi MARA (UiTM) Malaysia.Keywords: Carbon Footprint; Emissions; Greenhouse Gases; University; CampuseISSN: 2398-4287 © 2019.

Authors: Abd Razak Norfadzilah , Hashim Rugayah , Mohd Aminuddin Zaidi , Ismail Zuraidah
Published: November 2019

This paper aims to provide empirical evidence on the university students’ nutritional habits and peer pressure on food purchases. In addition, the motivations for the study were the media highlights on poverty among public university students that led to hunger. A survey was conducted with a sample size of 1,000 students; the response rate was 80%. The findings revealed the dietary patterns from money spent on food. Cross-tabulation between family income and the number of daily meals per day showed that students coming from a low-income background have satisfactory nutritional habits, but lack of money meant lesser meals or food insecurity. Hence, a snapfeed program for low-income student to assist with daily food intake was suggested.   Keywords: Needy students; poverty; dietary habits; food insecurity eISSN: 2398-4287 © 2019.

Patterns of Stationary Activities in the Elevated Pedestrian Networks of High-Density Asian Cities: The case of Mong Kok, Hong Kong
Authors: Villani Caterina , Talamini Gianni
Published: November 2019

Urban areas are increasingly failing to provide citizens with adequate and quality public open spaces. In this regard, Hong Kong characterises an extreme condition with 2.7-2.8 m2 of open space per capita. The burden of this scarcity falls most heavily on economically disadvantaged social groups, such as migrant domestic workers. In this context, grade separation pedestrian systems that were originally designed for mobility purposes, can provide space for sociability-oriented stationary uses. This study finds that the density of stationary activities in a typical elevated pedestrian network is as high as 1.2 person/m2.Keywords: Skywalk; Behavioural mapping; Stationary uses; Hong KongeISSN: 2398-4287 © 2019.

BACKGROUND

Traumatic brain injury (TBI) poses a significant threat to children’s health. Cognitive rehabilitation for pediatric TBI has the potential to improve the quality of life following the injury. Virtual reality (VR) can provide enriched cognitive training in a life-like but safe environment. However, existing VR applications for pediatric TBIs have primarily focused on physical rehabilitation.

OBJECTIVE

This study aims to design and develop an integrative hardware and software VR system to provide rehabilitation of executive functions (EF) for children with TBI, particularly in 3 core EF: inhibitory control, working memory, and cognitive flexibility.

METHODS

The VR training system was developed by an interdisciplinary team with expertise in best practices of VR design, developmental psychology, and pediatric TBI rehabilitation. Pilot usability testing of this novel system was conducted among 10 healthy children and 4 children with TBIs.

RESULTS

Our VR-based interactive cognitive training system was developed to provide assistive training on core EF following pediatric TBI. Pilot usability testing showed adequate user satisfaction ratings for both the hardware and software components of the VR system.

CONCLUSIONS

This project designed and tested a novel VR-based system for executive function rehabilitation that is specifically adapted to children following TBI.
Russian Contribution to the Periodic System
Authors: Baum Elena A. , Lunin Valeriy V.
Published: November 2019

For 50 years, scientists around the world have been searching for the relationship between the mass of atoms and the properties of elements, until the Russian scientist D.I. Mendeleev, having created the Periodic Table and formulated the Periodic Law, did complete this search. The discoveries of new chemical elements predicted by D.I. Mendeleev had soon followed and confirmed the fundamental importance of his Periodic law as the basic law of natural sciences. The works on the synthesis of transuranium and superheavy elements with serial numbers 113-118, been carried out by the scientists of the Joint Institute for Nuclear Research (Dubna, Russia) during the past 50 years, are the indisputable evidence of the validity of the Law of Periodicity of chemical elements and the proof of the Russian science triumph.

Published: November 2019

The 150th anniversary of the Mendeleev’s Periodic Table of elements requires scientists to rethink the outstanding role of this fundamental law in modern areas of chemistry, including such interdisciplinary and high-tech fields as nanochemistry and nanomaterials. The situation analysis shows that the most “nanotechnologically” popular elements belong to 1st, 2nd and partially to the 3rd periods, wherein a special practically important role is played by the noble metals because of their clear «specialization» in the development and implementation of new analytical techniques, in particular, the surface-enhanced Raman spectroscopy (SERS). There is an obvious need to develop and introduce fundamentally new, unique approaches and tools for the analysis of functioning living tissue structures. And SERS is precisely such a method, which implements multiplex, nonivasive spatially- and time-resolved control of chromoproteins at the extremely low concentrations in small volumes of samples of biological objects (tissues, cells, cell structures / organelles), and is an important innovative method of practical biomedical diagnostics.
Complexes of Rare- and Alkaline-Earth Elements in Catalytic Intermolecular Hydrophosphination of Multiple C—C Bonds
Authors: Lapshin Ivan V. , Kissel Alexander A. , Trifonov Alexander A.
Published: November 2019

In accordance with United Nations General Assembly resolution, the year 2019 was proclaimed the International Year of the Periodic Table of Chemical Elements. Rare-earth elements were discovered during the time of the Periodic System development. In the past few decades, their compounds have attracted great interest due to their unique reactivity. This review covers recent achievements in the field of intermolecular hydrophosphination of alkenes, dienes and alkynes, which is catalyzed by rare earth and alkaline-earth metal complexes. Catalytic hydrophosphination reaction is the addition of an P—H bond to С—С multiple bonds, and offers an efficient and elegant synthetic approach to production of the organophosphorus compounds widely used in industrial synthesis, pharmaceuticals, agrochemistry, and other areas. The high values of the ionic radii of rare earth and alkaline-earth metals in combination with the Lewis acidity provide their compounds with a pronounced tendency to complex formation and, accordingly, high coordination numbers. Due to high reactivity of M—E (E = C, H, N, P) bonds, ease of Ln—P ı-bond metathesis and multiple C—C bond insertions, these compounds offer new prospects for the catalysis of the alkenes and alkynes hydrophosphination. Therefore, complexes of non-toxic and relatively abundant in nature rare earth and alkaline earth metals can be a cheaper and more effective alternative to compounds of late transition metals in the catalysis of the C—P bond formation.

Volunteer group is one of the associations of community's political articulation in the electoral moment. By campaigning independence, non-partisan in nature, and moving in a collective way are proven able to make the volunteer group as an alternative actor and significant political force in mobilizing support and voice. Volunteer group Teman Ahok (Friends of Ahok) is a movement that openly declared itself as the political volunteer with political aims as an additional element in the winning of candidate pair Basuki Tjahaya Purnama (BTP) and Djarot Saiful Hidayat in the 2017 Jakarta gubernatorial election.  The appearance of Teman Ahok in the political arena of the 2017 Jakarta gubernatorial election is related to the BTP's populism figure. Quick changes in political escalation force Teman Ahok to change its position and political role. That fluctuation brings an important dynamic to the Teman Ahok journey. It is interesting to observe Teman Ahok activity in compile community participant and then aggregate it since it causes a public perception that is diametrically opposed at a time; supporting & not supporting. This writing will analyze the expression of Teman Ahok political voluntarism and will assess the significant benefit resulted in during the process of electoral democracy.
Cultural Tolerance, Diversity and Pluralism: The Recognition of Yogyakarta as The City of Tolerance
Authors: Kamil Muhammad
Published: November 2019

This paper intends to explore the areas of tolerance and intolerance to the diversity of the people of Yogyakarta amid cultural, racial and religious modernities. The City of Tolerance as an achievement that supports the national-ethnic tolerance of society is unable to create collective action. Structuring the meanings in the culture of the people of Yogyakarta actually gave birth to the expression of conflict and intolerance towards the minority. The pattern of conflictual relationships that sometimes involve violence has altered the structural dynamic order of a harmonious society.
Atlas narrativo de vidas na rua: experimentações éticas de uma metodologia
Authors: Pinheiro Diego Arthur Lima , Baptista Luis Antônio dos Santos
Published: November 2019

Este artigo problematiza as relações de poder que têm destituído a vida na rua de sua força de existir na atualidade, inviabilizando suas táticas de existência e deslegitimando sua presença na cidade. No intuito de investigar possíveis resistências a estes exercícios do poder, propomos a composição de um Atlas constituído por fragmentos narrativos produzidos no deslocamento pelo Centro Histórico de Vitória/ES realizado com a população de rua que ocupa esta região da cidade. O Atlas Narrativo visa explicitar a dimensão ético-política das ocupações realizadas por essa população. Ressaltamos o caráter minoritário que constitui essa experiência narrativa da cidade, atuando na constituição de pontos de passagem por onde se procurou pensar a dimensão inventiva da vida nas ruas sem abandonar-se, porém, a qualquer tipo de romantização de suas condições de vida. Concluímos no artigo como o Atlas possibilita pontos de vertigem capazes de abrir o pensamento a outra política da existência.

Published: November 2019

Benzamides are most widely used in medicinal chemistry and play a key role in biological action for treatment of various disorders such as anti-microbial, anti-malarial, anti-cancer, anti HIV, anti-viral, anti ameobic, anti-psychotic. The benzamide was used as an intermediate for synthesis of various medicinal compounds, in the present work; synthesization was carried out by using isatoic anhydride treated with various substituted anilines under acidic condition to form different substituted ortho-amino benzamide derivatives. Evaluation of the synthesized compounds were done by using the Insilico toxicity prediction methods with the aid of online software’s like OSIRIS, OCHEM, Molinspiration. These three softwares gave the drug score value of 3a, 3c, 3f, 3d and they are nearer to standard drug score value of 0.8. Toxicity prediction inferred that except 3e, other derivatives were safe to inhibit enzyme cytochrome P450 a subunit of CYP 1A2. The enzyme located in endoplasmic reticulum metabolizes the polyunsaturated fatty acids, steroidal hormones, vitamins, and also catalyzes hydroxylation reaction like hydroxyl estrogen from estrogen, 17-beta estradiols and has a major role in synthesis of all Trans retinol biosynthesis in liver. Invitro evaluation of Anti-microbial activity done by disc diffusion method, confirmed the compounds3eand3f had significant activity against Pseudomonas aeruginosa and the compounds3aand3dshowed significant activity against Bacillus subtilis, whereas the compounds 3c showed good activity against the organism Bacillus pumilus. Compound 3a showed moderate antifungal activity against Candida albicans. Thus in future benzamides can be considered as an effective intermediate for synthesis of different substituted quinoxaline derivatives.

Published: November 2019

Piezoelectric materials are widely used in electronic devices and, traditionally, various lead-based materials have been implemented in such applications. However, because of the damage caused by lead, other materials with similar characteristics that do not cause a negative impact on human health and the environment have been developed. A material with those characteristics is potassium-sodium niobite K0.5Na0.5 Nbo3. In this study, we investigate the thermogravimetric, structural, and microstructural properties of powders of such system obtained through oxide mixing with the aim of establishing the effect and efficiency of grinding (using a horizontal and a planetary ball mill grinder) on the production of the final material. It was determined that horizontal grinding and calcination at 900°C create the optimal conditions for obtaining K0.5Na0.5 Nbo3 powders, by oxide mixing, with the adequate structure and microstructure to continue the densification and/or doping processes.

This study aims to examine the achievement and improvement of the ability of mathematical connections and confidence of students through problem-based learning model. The population in this study is all students of 7th grade from one of SMP Negeri in Bandung. Samples were taken at random class. Among the eleven classes, two classes were selected as an experimental class (VII-K) and a control class (VII-B). The research instruments consist of a test instruments (math connection ability) and a non-test instruments. The instrument in the form of test is a set of test questions to measure students' mathematical connection ability. While non-test instruments in the form of a scale of students' self-confidence, and the scale of student opinions on problem-based learning. Research shows that the achievement and improvement of the ability of mathematical connections and confidence of students whose learning using problem-based learning model there is a difference with the learning using ordinary learning in terms of the initial ability level of students. There is no interaction between the problem-based learning model and the student's initial ability level to generate mathematical connections and students' self-confidence. In addition there is a correlation between the ability of mathematical connections and students' self confidence in the classroom that uses the problem-based learning model as well as in the classroom using ordinary learning.
