Degraded reality: Using VR/AR to simulate visual impairments

The effects of eye disease cannot be depicted accurately using traditional media. Consequently, public understanding of eye disease is often poor. We present a VR/AR system for simulating common visual impairments, including disability glare, spatial distortions (Metamorphopsia), the selective blurring and filling-in of information across the visual field, and color vision deficits. Unlike most existing simulators, the simulations are informed by patients' self-reported symptoms, can be quantitatively manipulated to provide custom disease profiles, and support gaze-contingent presentation (i.e., when using a VR/AR headset that contains eye-tracking technology, such as the Fove0). Such a simulator could be used as a teaching/empathy aid, or as a tool for evaluating the accessibility of new products and environments

Is the Industrial Product-Service System Really Sustainable

As the product-service system has shifted from its original concept to the Industrial PSS, its scope has expanded to include industrial products. Furthermore, the overall goal of reducing environmental impacts has been left behind. Despite the PSS's potential as a business model for a more sustainable production and consumption system, the mere addition of services to conventional products does not necessarily lead to a reduction of environmental impacts. This paper aims to discuss the concepts related to PSS, the need for considering environmental impact reduction as a critical issue for sustainability, and the role of ecodesign practices in the development of PSS

Oxygen isotope ratios of waters and respired CO2 in Amazonian forest and pasture ecosystems

Journal ArticleThe oxygen isotope ratio (d18O, SMOW) of atmospheric CO2 is a powerful indicator of large-scale CO2 exchange on land. Oxygen isotopic exchange between CO2 and water in leaves and soils controls the d18O of atmospheric CO2. Currently there is little empirical information on the spatial and temporal variation in the d18O of leaf and stem water in tropical ecosystems. We measured the seasonal dynamics of d18O in atmospheric CO2 and water in different ecosystem compartments in both primary forest and pasture ecosystems in three different regions of the Amazonian Basin of Brazil (Ji-Paraná, Manaus, and Santarém)

Sustainability index for agribusiness products considering territorial bases and life cycle thinking.

The sustainability index (SI) development for agricultural products was a Brazilian Agricultural, Livestock and Provisioning Ministry, (MAPA) demand. This work seeks by participative process, to define sustainability principles, criteria and agricultural products patterns. Theses principles have universal characters liable to expand its application to several agribusiness links by future criteria in the several territorial contexts through out the patterns to be defined to each biome monitored by satellites. The SI must have credibility and international recognition. Among their principles are: Conformity with the agreement, treaties and international conventions; Conformity with the national legislation; Localization; Integration; Monitoring and continuous improvement. The participative elaboration of the sustainability principles with the more representative agribusiness sectors, science and technology areas and the public and private institutions is allowing delineating the environment conduct, innovation and business for a future guiding to criteria formatting of the and SI patterns

Mapeamento de potenciais de impactos ambientais da queima de cana-de-açúcar no Brasil.

O artigo apresenta a distribuição espacial de alguns potenciais de impactos das emissões de monóxido de carbono (CO), metano (CH4), óxidos de nitrogênio (NOx) e óxido nitroso (N2O) causadas pela queimada de cana-de-açúcar no Brasil utilizando o SIG ArcGIS. As categorias de potenciais de impactos ambientais avaliados são: aquecimento global, formação de ozônio troposférico, acidificação e toxicidade humana
