Semi-analytical 3D solution for assessing radial collector well pumping impacts on groundwater–surface water interaction
Authors: Ameli Ali A. , Craig James R. 
Published: April 2017

Abstract
We present a new semi-analytical flow and transport model for the simulation of 3D steady-state flow and particle movement between groundwater, a surface water body and a radial collector well in geometrically complex unconfined aquifers. This precise and grid-free Series Solution-analytic element method approach handles the irregular configurations of radial wells more efficiently than grid-based methods. This method is then used to explore how pumping well location and river shape interact and together influence (1) transit time distribution (TTD) of captured water in a radial collector well and TTD of groundwater discharged into the river and (2) the percentage of well waters captured from different sources. Results show that meandering river shape plays a significant role in controlling the aforementioned metrics and that increasing the pumping rate has different consequences in different situations. This approach can also inform the design of water remediation and groundwater protection systems (e.g., river bank filtration and well head protection area).
A BATTLE AGAINST AIDS: NEW PYRAZOLE KEY TO AN OLDER LOCK-REVERSE TRANSCRIPTASE
Authors: K. Sony Jacob , Ganguly Swastika 
Published: April 2017

Objective: The reason for the failure of most of the anti-HIV drugs are their poor pharmacokinetics, the poor risk to benefit ratio and the drug resistance. With the objective of developing newer pyrazole scaffolds for effective treatment of HIV, binding mode analysis of designing ligands with the HIV-1RT protein and prediction of key ADME and toxicity parameters of the compounds was in an area of interest.Methods: In this study, molecular docking studies and ADME-T studies were carried out in designing of some novel pyrazole analogs. The protein (PDB ID: 1RT2) was prepared using the Protein Preparation Wizard (Schrodinger Glide 5.0). ADME parameters calculated by QikProp 3.0v and toxicity of designed analogs checked by using two different online software’s namely Lazar and protox.Results: Most of the designed pyrazole analogs have good oral absorption as well as good binding affinity towards HIV-1 reverse transcriptase.Conclusion: Finally total 5 analogs (SGS-2, 3, 12, 13 and 14) from the 14 designed leads were found to be best on the basis of molecular docking and ADME-T studies.
EURYCOMA LONGIFOLIA, A MALAYSIAN MEDICINAL HERB, SIGNIFICANTLY UPREGULATES PROLIFERATION AND DIFFERENTIATION IN PRE-OSTEOBLASTS (MC3T3-E1): AN IN VITRO MODEL

Published: April 2017

Objective: Eurycoma longifolia (EL), a well-recognized Malaysian medicinal herb, has gained widespread popularity due to its ability to protect against bone calcium loss in androgen-deficient osteoporosis. Nevertheless numerous animal studies have proved the bone protective effect of EL; however, the exact mechanism is not well-explained yet. Thus, the present study was aimed to explore the in vitro basis of bone protective effects of EL by using mouse pre-osteoblast cell line (MC3T3-E1).Methods: The cytotoxicity and proliferative potential of EL were evaluated by lactate dehydrogenase (LDH) and cell counting methods. Despite cell growth, the ability of EL to promote osteogenic differentiation of bone-forming cells was assessed by quantifying collagen (early differentiation marker) and calcium (late differentiation marker) in EL-treated bone forming cells.Results: Resulting data obtained from dose optimization study revealed that EL at 5 to 50 µg/ml concentration showed marked effects in significantly promoting cell growth in MC3T3-E1 cells. As such, resulting data also demonstrated the superior potential of EL in up regulating collagen synthesis and mineralization (calcium deposition) in MC3T3-E1 cells at 25 µg/ml, in comparison to untreated (negative control) and dihydrotestosterone (5α-DHT)-treated cells (positive control).Conclusion: These pronounced effects of EL on osteoblasts provide an in vitro basis for the bone protective potential of EL and thus can be considered as an alternative regimen for the treatment of androgen-deficient male osteoporosis.
9. Clinical and Practicum Education in the Professions: The Student Voice
Authors: Ralph Edwin , Wimmer Randy , Walker Keith 
Published: April 2017

Undergraduate students in professional education programs typically rate their clinical or practicum experiences as teh most important component of their entire pre-service preparation. This essay addresses the value of students’ views regarding the effectiveness of practicum programs. We summarize the views of 546 post-practicum students from three professional disciplines (engineering, nursing, and teacher education), concerning what they considered to be the most positive and negative aspectsof their respective practicum/clinical field-experiences.Our data analysis revealed three positive themes across the disciplines: the supportive interrelationships that students experienced; their own professional achievements; and their personal contribution to the welfare of their clients/pupils. Three negative elements also emerged: individual personal/professional challenges; site-based interpersonal conflicts; and policy or procedural problems with the program. Implications are raised for practicum administrators regarding the contribution of the student voice to clinical program enhancement.
18. Teaching for Epistemological Difference: Decentring Norms in Environmental Studies
Authors: Barrett M.J. 
Published: April 2017

Many environmental educators and philosophers have identified anthropocentrism and the socially constructed separation between humans and “the more-than-human world” (Abram, 1996) as primary root causes of current ecological devastation. This separation is embedded in Western schooling content and structures and is often unintentionally reinscribed by educational content and practices. This paper describes three ways I work to disrupt this artificial separation between humans and the non-human ‘nature’ within a graduate level course: 1) attention to discourses; 2) offering counternarratives; and 3) provision of experiences that support ways of knowing and being introduced in course readings and class lectures.
2. Using Creativity and Collaboration to Develop Innovative Programs That Embrace Diversity in Higher Education
Authors: Robinson A. Helene 
Published: April 2017

This paper provides an example of an innovative solution to program development that addresses the diverse needs of teacher educators throughout various geographical locations in Florida, through a collaborative multi-university, muti-agency teacher training program funded by one collaborative grant. Innovation is driven out of need, and I will discuss how I identified the needs at my university and then utilized creativity and collaboration to network and obtain the grant, which then facilitated, developed, and taught in a new M.Ed. program in Arts and Academic Interdisciplinary Education. Program content and delivery were both planned around the diverse student population within the multi-university collaboration, with each university designing diverse programs to address the specific needs of their population but with the same concept of arts integration. Collaboration also occurred within each university: the College of Arts and Science and the College of Education. In addition, teachers were required to collaborate as coaches in their schools to train and support others in increasing arts integration in their schools.
Drug Overdose Surveillance and Information Sharing via a Public Database: The Role of the Medical Examiner/Coroner
Authors: Williams Karl E. , Freeman Michael D. , Mirigian Lynn 
Published: April 2017

The medical examiner/coroner (ME/C) death scene investigation systems of the United States play a pivotal role in the current public health crisis created by the expanding drug dependency epidemic in the United States. The first point of recognition of a drug-related death in a community is often the local ME/C agency. This circumstance places these entities in an ideal position to provide surveillance data regarding the epidemiology of drug-related deaths occurring within the jurisdiction of the agency. The ability to surveil for the distribution and determinants among drug-related deaths at the first point of contact enhances the capacity to recognize actionable trends at the local, state, and national levels, including the ability to identify secular (longer-term) trends among various drugs and population subgroups, as well as activity spikes (outbreaks) associated with high-potency formulations and drug combinations. In this article, we describe the development and implementation of an online website that provides public access to a wide array of drug-related death surveillance resources and tools. The website gives users access to a detailed dataset that includes information regarding specific drugs, demographic information pertaining to the decedent, and to investigational findings related to the circumstances of the death. A unique aspect of the database is that it is populated by ME/C agencies and accessed by the public with no intermediary agency, so that the lag time between the identification and investigation of the death as drug-related and community knowledge of the circumstances of the death is minimized. Wide dissemination of accurate drug death surveillance information in an easily accessible and customizable format promotes societal awareness of the drug death epidemic, but also provides information to public health, law enforcement, regulatory, and other community-based organizations that can benefit from the most up-to-date knowledge. We envision a national system of surveillance at the regional ME/C level that would allow for optimal information dissemination and sharing. Such a system would likely allow for more efficacious allocation of resources at the regional and national level.

What's in an Iron Ring?
Authors: Roncin Andrew 
Published: April 2017

What do you get out of an engineering education? Is it technical knowledge, a peer network, or a way of thinking? Much of our work goes into teaching the technical skills. But the real value in engineering comes from our structured thinking.
In Canada, an engineering degree means that graduates are academically qualified to be engineers. Yet it takes at least another four year of apprenticeship to become a professional engineer. Engineers Canada expects us to teach engineers the fundamentals of engineering, and the skills for them to independently acquire the knowledge required for professional practice. So what is the purpose of engineering education? Is it technical competence, a structured way of thinking, or a set of principles? Do we focus on theory, design or ethics? Each of us has a different answer to these questions.
This presentation will challenge you to think about what it means to be an engineer and how we convey our common principles to young engineers.
TEACHING ANATOMY AND PHYSIOLOGY TO ENGINEERS IN THE BIOMEDICAL ENGINEERING PROGRAM
Authors: Moussavi Zahra , Lithgow Brian 
Published: April 2017

The merger of natural sciences with engineering and creation of biomedical engineering (BME) has brought innovation to the practice of medicine that could only be dreamed about a decade ago. By many accounts, we are now at the outset of Biomedical Century, and the need for engineers, natural scientists and physicians trained in biomedicine is greater than ever. While several universities in US and Canada have started BME program at the undergraduate level, many universities, particularly in Canada, have the BME program at graduate level with some BME related courses at undergraduate level. Therefore, we must be able to teach the fundamentals of human anatomy and physiology to students with engineering background, whom may have no background in biology.While a simple solution might be to refer students to take anatomy courses in the faculty of medicine, the author of this paper believes these courses would be much more efficient if they are taught by an engineer trained in medicine. There are three main approaches in engineering design: top-down and bottom-up and a blend of the two approaches [1-3]. There are many debates as which approach is most efficient in a particular area of science and philosophy. we believe engineers often use top-bottom approach for learning new concepts; through their main discipline, engineers, in general, learn the problem solving skills, in which they try to break a complex problem into several smaller problems and narrow down logically by cause and effect analysis; in another word they follow a top-down approach. Being trained with this approach, therefore, they may feel lost in a basic anatomy or physiology course as they often have a bottom-up approach in teaching the materials. This paper discusses the top-down approach in teaching anatomy and physiology to engineering students, and offers some insights for teaching BME courses.
SELF- AND PEER-ASSESSMENTS OF TEAM-EFFECTIVENESS IN A FIRST YEAR ENGINEERING DESIGN COURSE
Authors: Sheridan Patricia Kristine , Reeve Doug , Evans Greg 
Published: April 2017

Many first-year design courses in engineering take place in large classes (100-1000 students), where a significant portion of the student’s course grade is attributed to a team project. In these large classes most students receive limited, or no, personalized assessment or feedback to guide their ongoing learning of effectiveness in teams due to resource constraints (e.g. limited interaction time with instructors or teaching assistants). As a result, students are not provided a foundation upon which to continuously improve their effectiveness as they participate in different teams throughout their degree. A web-based tool is being designed to create a safe, virtual environment in which students can learn about their team-effectiveness competencies through the use of self- and peer-assessment in their project teams [1]. Specifically, this intervention provides students with a team-effectiveness framework to create a common language by which structured feedback can be provided based on observable behaviours and competencies.A pilot study to assess the utility of this framework in facilitating useful feedback was tested in the Winter 2012 term of a 250 student cornerstone design course, Praxis II, in first year Engineering Science. The objective of the study was to assess whether students can be guided to provide useful feedback on team-effectiveness to their teammates using our team-effectiveness framework.

The Canadian Manufacturers and Exporters Discovery Program is an annual competition where teams of high school students compete to design, build, and test a remote control hovercraft. The competition exposes students to the manufacturing process, from research and development, through to the product launch. Preuniversity teams from across Manitoba compete to build the hovercraft, write a business plan, and present their work to a panel of judges from academia and industry. The winning teams receive scholarships for postsecondary studies.This paper describes the Discovery Program hovercraft competition and lessons learned from the first four years of the program.
The iPad as an alternative to conventional technology for effective teaching
Authors: Sri Ranjan Ramanathan 
Published: April 2017

The iPad connected to a data projector in the class room can effectively replace conventional technology such as computers, overhead projectors, document cameras, and white boards. A selection of apps that can mimic the tasks of the existing technology will be demonstrated. The Keynote app can be used as the main tool for presenting the course content. The NotesPlus app can be used to replace the conventional overhead projector and the whiteboard. For those who are accustomed to the polythene rolls in the overhead projector, PaperView app will mimic the polythene roll with the ability to carry it around. A few apps to annotate .pdf files will be demonstrated. The BoardCam app will be used to mimic the document camera in teaching. The focus will be on demonstrating how the different apps are used seamlessly to present the course content to the students
The Application of Support Mechanisms to Increase the Success of Aboriginal Students
Authors: Herrman Randy 
Published: April 2017

the Engineering Access Program at the University of Manitoba has been in existence since 1985. It started with the mandate to improve the recruitment and retention of Aboriginal people in the Faculty of Engineering by introducing a selection of supports to these students. In order to improve the recruitment of Aboriginal students the requirements necessary for them to enter engineering have been lowered while keeping the requirements to obtain a degree the same. In order to lower the entrance requirements upgrading (or preparatory) courses were introduced into the program. In addition to the upgrading courses Student supports in ENGAP are comprised primarily of academic support, social support, financial aid, and personal support. In addition to the support network prospective students must attend a mandatory summer orientation aimed at preparing them for University studies. ENGAP has been very successful and now boasts 85 graduates of Aboriginal descent that work throughout the western provinces in various areas.
IMPLEMENTATION OF A CHUA CIRCUIT TO DEMONSTRATE BIFURCATIONS AND STRANGE ATTRACTORS IN A CLASS
Authors: Byagowi Ahmad , Kinsner Witold 
Published: April 2017

This paper describes the design and implementation of a Chua double-scroll circuit to demonstrate chaos in dynamical systems to students in a graduate course in order to enhance their visualization and understanding of strange attractor and Feigenbaum bifurcation trees.Teaching dynamical systems (i.e., nonlinear systems that can exhibit chaos) is often considered difficult because of the mathematical modeling involved and the inclusion of the fourth strange-attractor state, in addition to the traditional point stability, cyclic stability, and toroidal stability, as found in dynamic systems. A graduate course has been offered at the University of Manitoba for many years to provide both (i) a unified theory of fractal dimensions, together with many practical implementations of algorithms to compute the fractal dimensions, including the Rényi dimension spectrum that is required for characterization of the strange attractors using multifractal analysis.Leon Chua developed a simple nonlinear circuit capable of producing a rich collection of dynamic phenomena, ranging from fixed points to cycle points, standard bifurcations (period doubling), other standard routes to chaos, and chaos itself. The reason for selecting this specific circuit as a class demonstration tool is threefold: (i) the circuit has an analytical model and can be simulated, (ii) the circuit is implementable using available commercial off-the-shelf components, and (iii) the signals in the circuit can be acquired without affecting and altering its operation significantly.This paper describes the architecture, implementation, verification, and testing of the Chua system, as well as an analysis of the data obtained during the current phase of the development. Although there are many possible implementations of Chua’s circuit, our implementation has several innovative design features to make it more applicable to enhance students’ learning in the classroom.
Software Defined Radio Provides New Opportunities for Hands-on RF Education
Authors: Luther Erik , Dinolfo Julia , Katti Sachin 
Published: April 2017

RF and communications topics are traditionally taught using a theoretical, math-focused approach where students derive formulas and build simulations. Many educators see the value of adding a lab component so students can apply the theory with prototype implementations and experiment with live signals. However, the opportunity to do so is limited by a lack of affordable, accessible, and relevant tools. This paper describes how Stanford University enabled cutting edge, hands-on RF education in an undergraduate course. We share best practices for deploying a successful and affordable hands-on RF and communications lab using NI LabVIEW software and NI USRP radios. Students rated the class 4.94/5.0 - making it one of the highest ratings among all classes in the School of Engineering at Stanford University.

This course ECE 3730 Embedded System Design was introduced into the curriculum and designed specifically to correct an imbalance between computer and electrical engineering student pre-requisites; to address students studying only for the exam problem; and to directly assess student performance particularly in the CEAB attributes of Design, Investigation, Problem Analysis, and Tools.
INTERDISCIPLINARY CAPSTONE DESIGN STREAM AT THE UNIVERSITY OF WATERLOO: IMPLEMENTATION PLAN
Authors: Pearce Cherly , Lambert Steve , Parker Wayne 
Published: April 2017

An interdisciplinary design approach is a collaborative effort involving team members from different engineering disciplines to solve a problem. An opportunity for interdisciplinary education exists in the fourth year capstone design project. Interdisciplinary capstone courses are offered at other Canadian universities but, at the University of Waterloo (UW) the co-operative undergraduate engineering program poses a logistical barrier to students interacting with students in other disciplines for capstone design projects. Currently, students can form their own interdisciplinary team but differences in course structure, project deliverables, and design terminology and method between engineering disciplines is challenging for students and instructors. An investigation into the feasibility of a new interdisciplinary capstone design course at UW is undertaken. A possible home for the interdisciplinary capstone course could be under the Chair of Design Engineering. Overall, receptivity among departments is positive but a more comprehensive analysis is required.
