Authors: Euler Gallego Cartagena , Margarita Castillo RamÍrez , Walter MartÍnez Burgos 
Published: April 2017

Objective: The objective was to evaluate the effect of stressful and non-stressful conditions on the growth and production of pigments in a strain of Dunaliella salina (D. salina) isolated from the artificial saline of Manaure municipality, department of La Guajira, Colombia in laboratory conditions.Methods: Two treatments were performed, one in non-stressful growing conditions with medium J/1 to 1 M NaCl, 190-µmol. m-2. s-1, 5.0 mmol KNO3, pH 8.2 and another in stressful conditions with medium J/1 to 4.0 M NaCl, 390 µmol. m-2. s-1, 0.50 mmol KNO3, each in triplicate. Population growth was assessed by cell count, and the pigment content was performed by spectrophotometric techniques.Results: It was found that the conditions of stressful influences in the growth and the production of carotenoids of D. salina in comparison with those cultures not stressed. There was a significant difference between the average values of total carotenoids in the experiment with stressful conditions with 9.67±0.19 µg/ml and the experiment with conditions not stressful with 1.54±0.08 µg/ml at the level of significance of p<0.05.Conclusion: It was demonstrated that the stressful condition in the culture is associated with an increase in the production of lipophilic antioxidants, among these carotenoids. The knowledge of the stressful conditions for the production of carotenoids from D. salina isolated from the saline of Manaure opens a field in the use of this biotic resource with biotechnological purposes, production of new antibiotics, nutraceuticals and/or production of biofuels.

Authors: Attar Usmangani A. , Ghane Savaliram G. 
Published: April 2017

Objective: The aim of this study was to analyze phytochemicals, antioxidant potential and phenolic profiling of leaf and fruit extracts of Diplocyclos palmatus.Methods: The leaves and fruits were subjected for sequential extraction with hexane, chloroform, methanol and water. All extracts were subjected to biochemical studies such as phenols, tannins, flavonoids, terpenoids and antioxidant assays such as 1,1-diphenyl-1-picryl hydrazyl (DPPH), 2,2’ Azinobis (3-ethyl-benzothiozoline-6-sulfonic acid (ABTS), ferric reducing antioxidant property (FRAP), metal chelating and phospho- molybdenum reduction assay. Further methanolic extract was used for phenolics characterization by reversed phase-high performance liquid chromatography (RP-HPLC).Results: It was observed that methanol fruit extract showed significantly higher phenolics (9.29±0.01 mg tannic acid equivalent (TAE)/g extract), flavonoids (15.02±0.96 mg catechin equivalent (CE)/g extract) and terpenoids (276.73±0.76 mg ursolic acid equivalent (UAE)/g extract). However, chloroform extracts of leaf and fruit exhibited a high amount of tannins (22.07±0.06, 6.99±0.10 mg CE/g extract) respectively. The extracts were subjected to assess their antioxidant potential using various in vitro systems such as DPPH, ABTS, FRAP, metal chelating and phospho- molybdenum reduction. Among the various extracts, methanol fruit extract had highest DPPH radical scavenging activity (26.73±0.14 mg ascorbic acid equivalent (AAE)/g extract), metal chelating activity (0.80±0.01 mg EDTA equivalent (EE)/g extract) and phospho- molybdenum activity (291.24±2.19 mg AAE/g extract). In ABTS radical scavenging assay, aqueous leaf extract (12.11±0.07 mg trolox equivalent (TE)/g extract) showed the best response. The effective ferric reducing antioxidant property (141.54±10.12 mg Fe (II)/g extract) was exhibited by aqueous fruit extract. Overall, methanol and water were found to be the best solvents for the extraction of antioxidant compounds from fruit and leaf. In the RP-HPLC analysis, the major bioactive phenolic compounds such as catechin (CA) and hydroxybenzoic acid (HBA) were recorded in leaf as compared to fruit. In leaf, CA and chlorogenic acid (CLA) were principal compounds in leaf and fruit respectively. However, gallic acid (GA), HBA, CLA and vanillic acid (VA) were widespread in leaf and fruit. Conclusion: On the basis of the results, it was found that D. palmatus may serve as a novel and rich source of natural antioxidants and it can be further explored for pharmaceutical purposes.

Published: April 2017

In recent years engineering educators have been encouraged to blend technical and professional learning in their curricular and co-curricular programing (EC, 2009; NAE, 2004). Our paper describes a multifaceted leadership learning program developed to achieve this goal by infusing reflective, experiential learning into an otherwise technically oriented discipline. The program was designed by a collaborative team of educators and researchers with backgrounds in engineering, education, psychology, and industry and offers a range of learning experiences using diverse pedagogical strategies. The content covers four realms of leadership corresponding to four levels of analysis: self, team, organization, and society. Learning experiences include elective academic courses, co-curricular workshop programs, guest lectures in core courses, seminars, department based leadership groups, and panel discussions. In this paper, we describe the program goals, curricular and co-curricular initiatives and early research findings in order to scaffold an emerging discussion about engineering leadership education in Canada. Informal feedback from students who have participated in our program provide us with preliminary evidence that students are learning, that they value the learning opportunities afforded by our program and that our initiative is enabling significant personal growth.
Common Findings and Predictive Measures of Opioid Overdoses
Authors: Pelletier Danielle E. , Andrew Thomas A. 
Published: April 2017

Purpose This research examines autopsy findings from fatal opiate/opioid intoxications in New Hampshire for cerebral edema, pulmonary edema, and urinary bladder distension in the interest of finding predictability of such cases. Methods Autopsy reports of 150 decedents, between 20 and 40 years old, were reviewed. Subjects were divided into three groups as follows: 50 whose cause of death was opioid intoxication excluding fentanyl, 50 who died from fentanyl, and 50 who, lacking intoxication, died from cardiac issues, seizure disorders, or positional asphyxia as the control group. Autopsy reports were reviewed for cerebral edema, pulmonary edema, and urinary bladder distension. Results Pulmonary edema was present in 96% of those who died of fentanyl alone and in 94% of those who died of opioids excluding fentanyl. Cerebral edema occurred in 54% of decedents who died of opiates/opioids excluding fentanyl and 8% in those who died solely of fentanyl. Thirty-four percent of the fatal intoxications excluding fentanyl had bladder distension while only 16% of those who died of fentanyl intoxication. The control group found 30% had pulmonary edema, 2% had cerebral edema, and none had bladder distension. The triad occurred in 8% of intoxications and never in the control group. Conclusion The results validated correlation between opioid intoxication and pulmonary edema, cerebral edema, and bladder distension. Cerebral edema and bladder distension suggest opioid intoxication, but arise less frequently in fentanyl intoxication. We hypothesize that fentanyl causes death more rapidly than other opioids leading to these results. Given the variations, we do not recommend reliance on postmortem computed tomography in lieu of autopsy to evaluate potential fatal intoxications.

Authors: Dominguez Carolina , Perkins Ashley , Duque Alexandra , Bravo Viagnney 
Published: April 2017

Sudden death in infants due to primary cardiac tumors is extremely rare. Herein we describe a case of an 8-month-old male infant, without any previous medical history, who died in a hospital in the city of Medellín-Antioquia, Colombia. The family stated that approximately 15 minutes after he received a bottle, the baby became cyanotic and subsequently lost consciousness. He was taken to the hospital immediately; however, he arrived lifeless. As this was a sudden death case, the child was referred to the Institute of Legal Medicine and Forensic Sciences in the city of Medellín to clarify the cause, manner, and mechanism of death. The forensic autopsy revealed a eutrophic infant with central and peripheral cyanosis, without signs of trauma, and the internal examination found a single cardiac tumor in the anterior wall of the left ventricle. The mass was white and whorled; histological evaluation diagnosed a fibroma. The manner of death was natural due to a cardiogenic shock caused by a primary tumor.

PENGARUH ANEMON (Heteractis magnifica) TERHADAP VITALITAS IKAN BADUT (Amphiprion oscellaris) UNTUK MEMINIMALISASI PENGGUNAAN KARANG HIDUP PADA AKUARIUM LAUT BUATAN
Authors: Lubis Muhammad Zainuddin , Pujiyati Sri , Mujahid Muhammad 
Published: April 2017

Anemon laut adalah kerabat dekat dari karang. Binatang ini merupakan salah satu biota laut yang digemari oleh kalangan pecinta akuarium hias air laut. Bentuk tubuhnya menyerupai bunga karang dengan warna yang indah pada tubuhnya. Anemon laut ini merupakan hewan lunak yang tergolong dalam hewan invertebrata (hewan tak bertulang belakang). Ikan badut dan anemon laut biasa hidup dengan cara bersimbiosis, adapun simbiosis yang dilakukan adalah simbiosis mutualisme (saling menguntungkan). Namun, pada usaha budidaya ikan badut, banyak digunakan Anemon yang merupakan karang hidup. Penggunaan Anemon secara berlebih menyebabkan jumlah Anemon di ekosistem terumbu karang menjadi berkurang dan terancam menuju kepunahan. Hasil penelitian ini menunjukkan bahwa vitalitas Amphiprion oscellaris yang hidup dilingkungan akuarium buatan dengan kondisi lingkungan perairan yang ideal tidak dipengaruhi oleh simbiosis dengan Heteractis magnefica. Pemeliharaan ikan Amphiprion oscellaris di akurium tidak membutuhkan anemon laut untuk bertahan hidup, sehingga penggunaan anemon laut dapat diminimalisir dan mengganti dengan anemon buatan sebagai hiasan akuaskap.

The Leader-Engineer- Capabilities, Competencies, and Attributes
Authors: Reeve Doug , Evans Greg , Simpson Annie 
Published: April 2017

There is an urgent need for engineers to participate more fully in debate and decision-making to address the many challenges, local, national and global, that society faces. Engineering education provides graduates with technical competence but there are relatively few engineering programs that directly address development of leadership capability. At the University of Toronto, we have been developing leadership education since 2002 and presently offer wide-ranging curricular and co-curricular programming through Engineering Leaders of Tomorrow (LOT).
Leadership can be defined as “a relational and ethical process of people together attempting to accomplish positive change”. Adding leadership capability to an engineer creates a powerful combined capability. A leader-engineer has the capability to leverage and empower engineering competence with leadership competence.

A HOLISTIC, INTERDISCIPLNARY APPROACH TO THE DESIGN OF A SUSTAINABLE PERSONAL MOBIILTY SYSTEM
Authors: Buchal Ralph 
Published: April 2017

-For the past several years, undergraduate engineering students at Western University have been working on the design of a sustainable personal mobility system (SPMS). The vision of SPMS is to replace privately owned conventional cars with a sustainable mobility system built around shared lightweight electric vehicles, powered by renewable energy. In the 2011-2012 academic year, 13 undergraduate engineering students worked in five teams to further develop SPMS. They examined the economic and business feasibility of SPMS, and developed conceptual designs for the car-sharing system and vehicles. They reviewed the issues around climate change and renewable energy, and added to previous work by exploring the literature from different disciplines to learn more about car-sharing systems, electric vehicles, traffic network modeling and simulation, Monte Carlo simulation, vehicle layout and ergonomics. The students learned to take a holistic, interdisciplinary approach to the complex sociotechnical problem of sustainable personal mobility. While many students were initially uncomfortable with the ambiguity and ambitious scope of the project, they came to appreciate the many sociotechnical factors involved in designing an SPMS. An important learning outcome has been to increase student awareness and understanding of the environmental challenges facing society, as well as possible sociotechnicalsolutions.
INTEGRATING REGIONAL INDUSTRIAL THEME EXAMPLES IN PROCESS CONTROL EDUCATION
Authors: Deschenes Jean Sebastien 
Published: April 2017

A process control course was elaborated around the specific regional (industrial) context in which UQAR has an important mission of regional development. A multidisciplinary approach is used, integrating notions from various fields of engineering (electrical, mechanical, chemical and civil engineering) through theme examples such as wastewater treatment, pulp and paper making, mining and metallurgical extraction (mineral grinding). Laboratory activities on such processes are realized using a simulation software specifically designed for process control education. The small size of the groups at UQAR also allows to employ innovative strategies on how to run the activities and to evaluate the students. One laboratory on a real physical system (electrical motor) was also part of the course, to balance between the advantages of the software and the more “hands-on” laboratories. General feedback and comparative appreciation from students is then presented, followed by overall conclusions
Do Engineering – Anywhere, Anytime
Authors: Walters Mark , Luther Erik , Dinolfo Julia 
Published: April 2017

The need to create excitement about engineering has never been more critical. Our global community is faced with finding solutions to big challenges such as global warming, the energy crisis, and increasing demands on communications and urban infrastructure. To address these grand challenges, we require future engineers who are capable, innovative and equipped with practical skills in order to navigate from the design constraints to the solution. To encourage development of this practical skill, educators need to find ways to enable students to “do engineering,” anywhere, anytime. The three fundamental restrictions that prevent educators from being able to accomplish this are cost, accessibility to equipment – both in and out of the laboratory – and space and facilities. This paper discusses different ways in which educators are helping students connect with the world around them using graphical system design hardware and software technologies that are both affordable and scalable. We discuss flexible, compact, instrumentation platforms and illustrate how universities use this to enhance labs and improve practical experiences. We demonstrate how educators leverage low-cost, student-owned instrumentation hardware to teach concepts in students’ preferred environments, whether that is in the lab, library, or dorm room.
INTELLECTUAL PROPERTY (IP) FOR FUTURE ENGINEERS
Authors: Loiselle Michel , Olariu Dumitru 
Published: April 2017

The Canadian Intellectual Property Office (CIPO) is an agency of Industry Canada responsible for the administration and processing of the greater part of intellectual property (IP) in Canada. For example, during the last fiscal year, CIPO processed approximately 100,000 patents, trade-marks, copyrights and industrial designs applications. CIPO also plays a key role in supporting Canada’s innovation performance by delivering quality and timely intellectual property rights within a modern and competitive system. CIPO strives to increase Canada’s opportunities for innovation by promoting and disseminating IP rights and information to Canadian entrepreneurs, researchers and post-secondary students.In connection with the CEEA/ACEG Conference goals to enhance the competence of graduates from Canadian engineering schools through continuous improvement in engineering education and design education, CIPO has prepared a presentation to delegates on the subject of IP and the use of IP Case Studies as a means to raise the awareness of IP amongst engineering students. During this presentation, participants will leave with a better understanding of IP and will have the opportunity to exchange on the subject; as well as understand which teaching tools are available to assist engineering faculty in introducing IP in their classrooms.
Complexity Made Simple
Authors: Kruchten Philippe 
Published: April 2017

We present a simple conceptual model of what constitutes complexity and simplicity in design engineering. At the core of the model are the three concepts of 1) scale (how many things are there), 2) diversity (how many different kinds of things are there), and 3) connectivity (how many relationships are there between things). The model distinguishes essential from accidental complexity (i.e., the complexity that we, engineers, add while designing), and intrinsic versus perceived complexity. The model also articulates the complexity of the thing (or system) we design or observe versus the complexity of the community around the system: its users, designers, manufacturers, sellers, other systems, etc. This model is then used to articulate a set of heuristics to address complexity: reduce, hide, shrink, organize, explain, expose.. Finally we open the toolkits of engineers in various disciplines to identify strategies, methods, or tools that they can use to address complexity: design principles, guidelines, design methods, patterns, tactics, frameworks, etc. Approaches such as modeling, abstraction, partitioning can then be described in terms of our key concepts and heuristics; e.g., “abstraction reduces perceived complexity”. This conceptual model helps engineering students to better reflect on their practices of design, and how these practices vary across disciplines. It also provides a more systematic approach to answering the never ending question: “how can you make this simpler?”

Professors, instructors and technical staff atvarious universities often face difficult questions regarding the tools and hands-on skills taught in the curriculum during a limited laboratory time. Therefore, to complement the classroom experience, students in Electrical and Computer Engineering at the University of Manitoba have developed and delivered a number of workshops on topics that have a direct impact in the classroom and job prospects, while encouraging independent learning and experimentation to foster lifelong learning skills. This paper describes the organization and examples from organizing more than 20 workshops that reached excess of 250 undergraduate students, graduate students, high school students, high school teachers, recent graduates, industry professionals, and hobbyist.
