Appropriate Aims: Setting Boundaries for Reprogenetic Technology

Not too long ago, ten fingers and ten toes defined a successful birth. Not too far from now, ten fingers and ten toes will be just the beginning. Parents always hope for a healthy baby, and medical advances continue to help secure the fulfillment of this hope. But reprogenetics, a new combination of technology and science that allows us to choose the genes, and thus the traits, of the children we create, is raising new questions about what it means to have a healthy baby

Biourbanism for a healthy city: biophilia and sustainable urban theories and practices

The paper was given via audio/slides file on 4th September 2012 in the International Convention on Innovations in Engineering and Technology for Sustainable Development, 3-5 September 2012, in Bannari Amman Institute of Technology, Erode District, Tamil Nadu, India. The paper was peer reviewed and accepted in July 2012.Vital elements in urban fabric have been often concealed for reasons of design. Recent theories, such as Biourbanism, suggest that cities risk becoming unstable and deprived of healthy social interactions. Our paper aims at exploring the reasons for which,fractal cities, for example can have beneficial impact on human fitness of body and mind. During the last few decades, modern urban fabric lost some very important elements, only because urban design and planning became stylistic patterns of fancy aerial views to show mainly iconic signature architecture. Biourbanism attempts to reestablish lost values and balance, not only in urban fabric, but also in reinforcing human-oriented design principles to be easily implemented and understood. The Lancet Commission of Healthy Cities provides an analysis of how health outcomes are part of the complexity of urban processes, highlighting the role that urban planning can, and should play in delivering health improvements through processes of reshaping the urban fabric of our cities around the globe. This paper describes how the application of Biourbanism’s principles can improve the quality of the urban environment with reference to both physical transformations of it and psychological impact upon city inhabitants. Therefore, these principles are accomplished to support urban structural sustainability.ADT and School of Technology funds

Raman spectroscopy of human teeth using integrated optical spectrometers

We have designed an arrayed-waveguide grating in silicon oxynitride technology for the detection of Raman signals from tooth enamel in the spectral region between 890 nm and 912 nm. The detected signals for both parallel and cross polarizations are used to distinguish between healthy and carious regions on the tooth surface of extracted human teeth. Our experimental results are in very good agreement with those achieved using conventional Raman spectrometers. Our results represent a step toward the realization of compact, hand-held, integrated spectrometers
