INTRODUCTION: Biotechnology is a new bachelor degree in UFPA, and has been stablished with excellency in the state of Pará. However, there is the need to promote comprehension and learning in Biochemistry, as well as interdisciplinarity, that is an essential part of biotechnology. OBJECTIVES:  To increase learning and interdisciplinarity, educational games were used as tools. The students were instigated to develop educational games in different topics of energy metabolism. MATERIALS AND METHODS: The games were developed to be used in any teaching environment, since they were made with low-cost and accessible materials. This strategy was applied in three semesters in different Biochemistry classes, between 2012 and 2014. The best games in each class were used in following semesters. DISCUSSION AND RESULTS: Since the first semester, the failing rates dropped 15% compared to the previous semester, in which educational games were not used. An increase in learning (by observation) could be noticed, including comprehension of metabolic pathways and their conections. Twenty games were developed in three semesters, and four of them are still being improved and used in other classes. The participant students answered a questionnaire, in which 47% defined the games as “Relaxing and Instigating”, 33% said the games “Accomplished their didactic and educational role” and 54% said they would recommend the use of these games as a reviewing activity. At the moment, another approach is being used to teach Biochemistry – Gamification, which uses elements found in games, as conflict, cooperation, rules and fun, to improve students’ motivation and engagement. CONCLUSION: As a partial result, there was greater in-class interest and engagement, better comprehension of the course content and the activities gave the students the opportunity to work in groups, to think critically about the themes and to develop opinions based on interdisciplinar and formal knowledge.

Gene Data

AbstractGlobal oceanographic monitoring initiatives originally measured abiotic essential ocean variables but are currently incorporating biological and metagenomic sampling programs. There is, however, a large knowledge gap on how to infer bacterial functions, the information sought by biogeochemists, ecologists, and modelers, from the bacterial taxonomic information (produced by bacterial marker gene surveys). Here, we provide a correlative understanding of how a bacterial marker gene (16S rRNA) can be used to infer latitudinal trends for metabolic pathways in global monitoring campaigns. From a transect spanning 7000 km in the South Pacific Ocean we infer ten metabolic pathways from 16S rRNA gene sequences and 11 corresponding metagenome samples, which relate to metabolic processes of primary productivity, temperature-regulated thermodynamic effects, coping strategies for nutrient limitation, energy metabolism, and organic matter degradation. This study demonstrates that low-cost, high-throughput bacterial marker gene data, can be used to infer shifts in the metabolic strategies at the community scale.

Powerful Strategy

Lignocellulosic residues are low-cost abundant feedstocks that can be used for industrial applications. However, their recalcitrance currently makes lignocellulose use limited. In natural environments, microbial communities can completely deconstruct lignocellulose by synergistic action of a set of enzymes and proteins. Microbial degradation of lignin by fungi, important lignin degraders in nature, has been intensively studied. More recently, bacteria have also been described as able to break down lignin, and to have a central role in recycling this plant polymer. Nevertheless, bacterial deconstruction of lignin has not been fully elucidated yet. Direct analysis of environmental samples using metagenomics, metatranscriptomics, and metaproteomics approaches is a powerful strategy to describe/discover enzymes, metabolic pathways, and microorganisms involved in lignin breakdown. Indeed, the use of these complementary techniques leads to a better understanding of the composition, function, and dynamics of microbial communities involved in lignin deconstruction. We focus on omics approaches and their contribution to the discovery of new enzymes and reactions that impact the development of lignin-based bioprocesses.

Although digital technology has the potential to address the challenges of access, engagement, and scalability that psycho-social prevention interventions face when trying to reach families of primary school children, existing research on technology-enabled interventions for families remains limited. The aim of this qualitative pilot study was to investigate the engagement, acceptability, and initial subjective indicators of emotion regulatory effects during 1-week in-situ deployments of a low-cost, bespoke prototype, which has been designed to support children's in-the-moment emotion regulation. This prototype instantiates a novel intervention model that aims to address the existing limitations by delivering the intervention through an interactive object (a `smart toy') sent home with the child, without any prior training necessary for either the child or their carer. Ten families (altogether 11 children aged 6-10 years) were recruited from three underprivileged communities in the UK, and children were given the toy to keep at home for 7-8 days, after which we interviewed each child and their parent about their experience with the toy. Across all 10 families, participants reported that the toy was incorporated into children's emotion regulation practices and engaged with naturally in moments children wanted to relax or calm down. The data suggest acceptability of the toy from both parents and children, strong engagement and indications of emotion-regulatory effects. More broadly, our findings suggest the potential of a technology-enabled shift in how prevention interventions are designed and delivered: empowering children and parents through `child-led, situated interventions', where participants learn through actionable support directly within family life, as opposed to didactic in-person workshops and a subsequent skills application.

The e-services have introduced a significant wave of change in communication patterns around the world. Such e-services are capable of intelligent interaction and are able to discover and negotiate with each other, mediate on behalf of their users and reconfigure themselves into services that are more complex. In this chapter, the author explores the future opportunities and its applications of ambient eservice. Contrast to traditional e-business service delivery method, their proposed service focus on the bottom-up collaborative approach that enables e-business participants to cooperate with nearby users and encourage information sharing and experience co-creation. The notion of ambient e-service is defined to identify a new scope of mobile e-service, which address dynamic collective efforts between mobile users (enabled by Mobile Peer-to-Peer technology), dynamic interactions with ambient environments (envisioned by Location-Based Service), the moment of value (empowered by wireless technologies), and low cost service provision. Several ambient e-service application scenarios will be introduced in the following sections.

Most of the existing mobile services were designed based on the client/server architecture. Those mobile services neither paid much attention to mobile users’ interactions with their environments nor considered the collective efforts between the mobile users in a dynamic peer group. In this article, the notion of ambient e-service is so defined as to identify a new scope of mobile e-service, which address dynamic collective efforts between mobile users (enabled by mobile peer-to-peer technology), dynamic interactions with ambient environments (envisioned by location-based service), the moment of value (empowered by wireless technologies), and low cost service provision. The notable features of ambient e-services are the exhilarated linkage based on social context and significantly rapid growth of connections. We also present an ambient e-service framework that characterizes ambient e-services with three dimensions (value stack, environment stack, and technology stack), followed by several exemplars of ambient e-service applications. Moreover, we present the ambient e-service embracing model (ASEM) that addresses the integrated consideration of trust, reputation, and privacy required for fostering the growth of ambient e-services and steers the directions of future fruitful relevant research.

Remote Sensing using unmanned aerial vehicles (UAV) is gathering a lot of attention at the moment by researchers and developers, especially in terms of low-cost aircrafts which still maintain sufficient accuracy and performance. This paper introduces a low-cost approach to increase airworthiness by using a forward-looking camera to estimate the attitude of a UAV. It not only focuses on using machine learning to classify ground and sky, but also uses image processing and software engineering methods to make it fault-tolerant and really applicable on a miniature UAV. Additionally, it is able to interface with an autopilot framework to being used productively on flight missions.

Alignment Errors

Current heliostats cost ∼$200/m2 of reflective area and are estimated to contribute up to 50% of the total solar power tower plant costs. A drastic overall cost reduction is required in order for concentrated solar thermal power to be economically viable. The Department of Energy has set forth the SunShot initiative targeting a levelized cost of energy (LCOE) of $0.06/kWh by the year 2020. The cost of each heliostat must be brought down to an estimated $75/m2 to achieve this rigorous goal. One of the driving aspects of heliostat design and cost are the heliostat optical errors. At the moment, it is relatively unclear about the amount of error that can be present in the system while still maintaining low cost and high optical accuracy. The optical errors present on heliostat mirror surfaces directly influence the plant LCOE by causing beam spillage. This can result in an increase in the number of heliostats, an increased receiver size, and decreased thermal efficiency. Assuming a fixed heliostat cost of $75/m2, the effects of optical errors on LCOE were evaluated within the software delsol. From a probabilistic analysis, beam quality errors (i.e., slope error, alignment errors, etc.) were shown to have more importance on the LCOE than tracking errors. This determination resulted in a realization that the tracking errors and beam quality errors could be combined into a “bundled” root-sum-square (RSS) error value and produce similar results in delsol. A “bundled” error value of 2 mrad resulted in an LCOE of $0.06/kWh. This “bundled” value was the basis for a new optical error budget and is decomposed into five individual errors. These five errors can be used as design specifications for new generation heliostats.

Emptying Time

Due to the difficulty in determining polar compounds (PC) using the IUPAC method 2.507, simple and low cost devices for in situ determinations, such as Viscofrit, are commercialized for fried food processing establishments. This device is calibrated for oils but not for fats, such as beef tallow, since materials with a high melting point are rarely used worldwide. A large dispersion was observed in the measurements made with Viscofrit at 48 °C on thermoxidized beef tallow. The maximum emptying time was reached at about 6 hours of thermoxidation, at which point the fat still does not reach the maximum PC level allowed. In this test, a great dispersion in the data and a high percentage of “false values” were observed, which may be due to the presence of fatty solids at the measurement temperature, which affect the emptying time. In order to use Viscofrit for fats, such as beef tallow, it is suggested to perform a calibration at a temperature outside the range established by the manufacturer which ensures the absence of fatty solids, in this case 60 °C. Under these conditions, a maximum emptying time of 37 seconds was obtained.

The article substantiates the expediency of the implementation of the advanced learning in the process of fundamental mathematical training of bachelors in the field of electronics and telecommunications. At the moment, the field requires mandatory (deep) knowledge of the main classical sections of mathematics, it is also important to acquaint students in higher mathematics with elements of modern mathematical theories, concepts that allow learners to better understand special courses in mathematics and relevant special disciplines. materials of mathematics, which are used in the modern mathematical models of technical developments. The aim of the article is to reveal the approaches to the concept of the advanced learning in the process of fundamental mathematical training of future bachelors in the field of electronics and telecommunications.The main methods that were implemented in the study of the problem of advanced learning were the analysis and synthesis of the scientific sources on the selected problem, observation, implementation of projects and evaluation of their results. It is offered (from the first semester) to introduce generalized concepts (norm, operator, etc.) in time, to acquaint with ideas of variational calculus, functional analysis, mathematical methods of research of linear equations with variable coefficients, theory of stochastic approximation, mathematical modelling. Then the future specialist will be able to comprehend the objects, which have been already developed by mathematicians but have not been used yet. Thus, a difficult topic or concept can be considered in advance in some connection with the currently studied material. For example, during the study of a function and the construction of its graph, along with the asymptote, students can be introduced to the approximation of the function, the concepts of interpolation and approximation. It is expedient to acquaint students with these problems more deeply during performance of independent tasks (consultations, the abstract, the report at conference, etc.).

Abstract ME6101: Engineering Design is a graduate level course offered by The George W. Woodruff School of Mechanical Engineering at the Georgia Institute of Technology. The course is orchestrated to achieve three objectives, namely, to have students internalize the Pahl and Beitz design method, to help them “reinvent” the Pahl and Beitz design method to meet the challenges of the future, and most importantly, to learn how to continue learning about design. The course was given during the Fall 2000 semester to a class of nineteen students — most in their first semester of graduate school — in addition to six practicing engineers via a distance-learning program. In this paper, the techniques utilized to foster learning in ME6101 are described. Excerpts from students’ essays are presented as anecdotal evidence that the concerted use of these methods aids students both in the internalization of course content and the development of personal practices that will serve them well in and beyond their engineering careers.
