Can design documentaries disrupt design for disability?
This paper shows how design documentaries can motivate new perspectives for design and disability. We critically consider the ways in which design documentaries can foreground children's lived experiences and priorities, in cases where it is not always possible to involve children early on in the design process. By presenting a design case for supporting communication that involves children with severe speech and physical impairments and their social peers, we discuss how this narrative method can evoke designer empathy and guide new interpretations. Our findings show that design documentaries can convey to designers rich and multifaceted accounts of children's communication experiences. Although this is found to be generative, we also identify a tension with a bodily impairment understanding of disability. Drawing on reflections from our case study, we propose new methodological implications for embedding design documentaries in the design process of technologies for disability
Pegamento De Enxertos De Tomateiro Em Diferentes Solanáceas
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES)This paper aimed to assess tomato grafting on different solanaceous species through two grafting methods. Scions were cut from cultivar Santa Cruz Kada seedlings. A fully randomized experimental design was carried out with treatments in a 9 x 2 factorial scheme. As rootstocks, four accessions of mini-tomatoes (0224-53, RVTC 57, RVTC 20 and 6889-50 Solanum lycopersicum L); two species of wild tomato (Solanum habrochaites var hirsutum ‘PI-127826’ and Solanum pennellii ‘LA716’); other two tomato species [Solanum, cocona (Solanum sessiliflorum) and physalis (Physalis peruviana)] and a control with cultivar Santa Cruz Kada (auto-graft) rootstocks were used. In addition, two grafting methods were evaluated full cleft and approach graft. Fifteen days after grafting, plants were assessed for graft-take percentage; root length; plant height; leaf number; foliar area; root, stem and leaf dry matter; and ratio between shoot and root dry matter. Based on the results, we may state rootstock and grafting interaction had effect on both graft-take rate and plant development. Overall, the studied plants should be recommended as rootstock, except for 6889-50 mini-tomato (S. lycopersicum L.) and S. pennellii. Full cleft grafting was most suitable for cocona and physalis, while the approach method showed better results for the mini-tomato accessions 0224-53, RVTC 57 and RVTC 20, as well as for S. habrochaites. © 2016, Universidade Federal Rural do Semi-Arid.

Underwater energy harvesting to extend operation time of submersible sensors
A linear electromagnetic energy harvesting device for underwater applications, fabricated with a simple manufacturing process, was developed to operate with movement frequencies from 0.1 to 0.4 Hz. The generator has two coils, and the effect of the combination of the two coils was investigated. The experimental study has shown that the energy capture system was able to supply energy to several ocean sensors, producing 7.77 mJ per second with wave movements at 0.4 Hz. This study shows that this energy is enough to restore the energy used by the battery or the capacitor and continue supplying energy to the sensors used in the experimental work. For an ocean wave frequency of 0.4 Hz, the generator can supply power to 8 sensors or 48 sensors, depending on the energy consumed and its optimization.This work is co-funded by the project K2D-Knowledge and Data from the Deep to Space with reference POCI-01-0247-FEDER-045941, co-financed by European Regional Development Fund (ERDF), through the Operational Program for Competitiveness and Internationalization (COMPETE2020) and by the Portuguese Foundation for Science and Technology-FCT under MIT-Portugal Program.

A versatile capillary gel electrophoresis methodology for in-process and final product characterization of virus-based targets
The biopharmaceutical industry is approaching a turning point where new therapeutic modalities such as virus-based biopharmaceuticals are used in several applications such as vaccination, gene therapy and oncolytic therapy. However, the bioprocess of functional viruses still presents challenges, namely due to the availability of suitable analytics for downstream processing monitoring or characterization of the final product. Capillary electrophoresis (CE) is a versatile technique that enables the determination of intact or reduced particle number and the quantification of several product-related impurities, such as host cell DNA and host cell proteins. Although this f platform is commonly used for purity profiling of monoclonal antibodies in the pharmaceutical industry by ultraviolet (UV) detection, it requires a large amount of product, making it not suitable for virus-based pharmaceuticals, where total protein concentration (dose) is relatively low.
This work presents a highly sensitive CE methodology for monitoring different bioprocess steps and final product characterization of several viral vectors. A fluorescence labelling procedure using the (3-(2-furoyl) quinoline-2-carboxaldehyde dye was used, enabling the detection of the viral proteins through Sodium dodecyl sulfate-capillary gel electrophoresis (CE-SDS) method coupled to a laser-induced fluorescence (LIF) detector.

Numerical and experimental characterisation of polylactic acid (PLA) processed by additive manufacturing (AM): bending and tensile tests
In additive manufacturing (AM), one of the most popular procedures is material extrusion
(MEX). The materials and manufacturing parameters used in this process have a significant impact on
a printed product’s quality. The purpose of this work is to investigate the effects of infill percentage
and filament orientation on the mechanical properties of printed structures. For this reason, the
characterisation of polylactic acid (PLA) was done numerically using the finite element method and
experimentally through mechanical tests. The experiments involved three-point bending and tensile
tests. The results showed that mechanical performance is highly dependent on these processing
parameters mainly when the infill percentage is less than 100%. The highest elastic modulus was
exhibited for structures with filament align at 0◦ and 100% infill, while the lowest one was verified for
specimen filament aligned at 0◦ and 30% infill. The results demonstrated that the process parameters
have a significant impact on mechanical performance, particularly when the infill percentage is less
than 100%. Structures with filament aligned at 0◦ and 100% infill showed the maximum elastic
modulus, whereas specimens with filament oriented at 0◦ and 30% infill showed the lowest. The
obtained numerical agreement indicated that an inverse method based only on the load–displacement
curve can yield an accurate value for this material’s elastic modulus.National Innovation Agency (ANI) for MSc grant of Mariana Salgueiro nº POCI-01-0247-

Design Opportunities for AAC and Children with Severe Speech and Physical Impairments
Augmentative and alternative communication (AAC) technologies can support children with severe speech and physical impairments (SSPI) to express themselves. Yet, these seemingly 'enabling' technologies are often abandoned by this target group, suggesting a need to understand how they are used in communication. Little research has considered the interaction between people, interaction design and the material dimension of AAC. To address this, we report on a qualitative video study that examines the situated communication of five children using AAC in a special school. Our findings offer a new perspective on reconceptualising AAC design and use revealing four areas for future design: (1) incorporating an embodied view of communication, (2) designing to emphasise children's competence and agency, (3) regulating the presence, prominence and value of AAC, and (4) supporting a wider range of communicative functions that help address children's needs
