Title Light desynchronosis and health Type Journal Article
Year 2019 Publication Light & Engineering Abbreviated Journal
Volume 27 Issue 3 Pages 14-25
Keywords Human Health; Review
Abstract The review summarizes the modern knowledge of the impact of day-night, light-darkness rhythm disorders on the aging process and on the risk of development of the age-related conditions. Significant evidence has been obtained of that the constant artificial illumination and the daylight of the North has a stimulating effect on the occurrence and development of tumours in laboratory animals. It has been shown that long-term shift work, trans-meridian flights (jet-lag) and insomnia increase the risk of cardiovascular diseases, diabetes mellitus, and malignancies in humans. Particular attention is given to the studies where the relationship between light intensity, light wavelength and its ability to suppress the synthesis of melatonin produced at night in the pineal gland, are investigated. It has been established that melatonin synthesis is most effectively suppressed with blue light sources of a wavelength from 446 to 477 nm. The use of exogenous melatonin prevents premature aging of the reproductive system and the body as a whole prevents the development of immune-suppression, metabolic syndrome and tumours caused by light pollution. An urgent task is to develop recommendations for optimizing the illumination of workplaces and residential premises, of cities and towns as a prevention measure for premature aging and age-related pathology, which, ultimately, will contribute to the long-term maintaining of performance and improving the quality of life.

Title Response of conifer species from three latitudinal populations to light spectra generated by light-emitting diodes and high-pressure sodium lamps Type Journal Article
Year 2015 Publication Canadian Journal of Forest Research Abbreviated Journal Can. J. For. Res.
Volume 45 Issue 12 Pages 1711-1719
Keywords plants
Abstract Light-emitting diode (LED) technology shows promise for supplementing photosynthetically active radiation (PAR) in forest nurseries because of the potential reduction in energy consumption and an ability to supply discrete wavelengths to optimize seedling growth. Our objective was to examine the effects of light spectra supplied by LED and traditional high-pressure sodium (HPS) lamps on growth and physiology of Pseudotsuga menziesii (Douglas-fir) and Picea engelmannii (Engelmann spruce) seedlings. We used three latitudinal sources for each species: British Columbia (BC), Idaho (ID), and New Mexico (NM). Container seedlings were grown for 17 weeks in the greenhouse under an 18-h photoperiod of ambient solar light supplemented with light delivered from HPS or LED. In general, seedlings grown under LED had significantly greater growth, gas exchange rates, and chlorophyll contents than those seedlings grown under HPS. The growth and physiological responses to supplemental lighting varied greatly among species and seed sources. Generally, LED-grown seedlings from BC had the greatest growth and tissue dry matter followed by ID and NM populations. Compared with HPS, the significant increase in seedling growth and concomitant energy savings with LED (29% energy consumption relative to HPS) demonstrates the promise of using LED as PAR supplemental lighting for container seedling production.

Title Alternatives to artificial lighting: Varying patterns of bio-light in architecture Type Journal Article
Year 2020 Publication Archidoct Abbreviated Journal
Volume 8 Issue 1 Pages 80-91
Keywords Lighting
Abstract The notion of variability is identical to the phenomenon of light.The present paper examines characteristics that shape this variability, in all forms of light, both natural and artificial, as well as light that is experimentally produced in a laboratory environment, through genetic modification of plants, in line with current trend of architectural fluidity. At a time when architecture is interacting with emerging technologies by creating parametrically changing shells and environments, that are evolving as biological models and organisms, lighting is becoming a tool for highlighting forms while ensuring the functionality of spaces. It is up to the designer to manage these variables of light in an inspired way, in order to create an elegant, sustainable and environmentally friendly environment for all beings.

Title Redesigning the exterior lighting as part of the urban landscape: The role of transgenic bioluminescent plants in mediterranean urban and suburban lighting environments Type Journal Article
Year 2020 Publication Journal of Cleaner Production Abbreviated Journal Journal of Cleaner Production
Volume 242 Issue Pages 118477
Keywords Plants; Lighting
Abstract This research discusses the feasibility of replacing or supporting artificial lighting with Transgenic Bioluminescent Plants (TBP), as a means of minimizing light pollution, reducing electrical energy consumption and de-carbonizing urban and suburban outdoor environments, creating sustainable conditions and enriching the quality of life. Until now, no information is given about the light output of any TBPs and the question “Are the TBPs capable of producing the necessary lighting levels for exterior lighting?” is unanswered. For this reason, a new methodology is proposed for selecting and analyzing the lighting output potential of transgenic plants ted for specific climatic conditions. This methodology considers growth and reduction factors, as well as a formulae for estimating the plants’ luminous output by performing light measurements. Results show that transgenic plants in medium growth can emit a median luminous flux of up to 57 lm, a value that can definitely support low lighting requirements when used in large numbers of plants. From the lighting measurements and calculations performed in this research, the light output of the TBPs for a typical road with 5m width was found equal to 2lx. The amount of plants required was 40 at each side of the road for every 30m of streets with P6 road class. The results show that the use of bioluminescent plants can actually contribute to the reduction of energy consumption, concerning only the lighting criterium, thus creating an enormous opportunity for a new state-of- the-art market and research that could potentially minimize CO2 emissions and light pollution, improve urban and suburban microclimate, mitigate the effects of climate change, as well as provide an alternative means of lighting affecting both outdoor lighting design and landscape planning in suburban and urban settings. Moreover, further research should be applied considering also other possible ecological impacts before applying TBPs for exterior lighting applications.

Title Predictive mapping of the global power system using open data Type Journal Article
Year 2020 Publication Scientific Data Abbreviated Journal Sci Data
Volume 7 Issue 1 Pages 19
Keywords Remote Sensing
Abstract Limited data on global power infrastructure makes it difficult to respond to challenges in electricity access and climate change. Although high-voltage data on transmission networks are often available, medium- and low-voltage data are often non-existent or unavailable. This presents a challenge for practitioners working on the electricity access agenda, power sector resilience or climate change adaptation. Using state-of-the-art algorithms in geospatial data analysis, we create a first composite map of the global power system with an open license. We find that 97% of the global population lives within 10 km of a MV line, but with large variations between regions and income levels. We show an accuracy of 75% across our validation set of 14 countries, and we demonstrate the value of these data at both a national and regional level. The results from this study pave the way for improved efforts in electricity modelling and planning and are an important step in tackling the Sustainable Development Goals.
