Title Night light intensity and women's body weight: Evidence from Nigeria Type Journal Article
Year 2018 Publication Economics and Human Biology Abbreviated Journal Econ Hum Biol
Volume 31 Issue Pages 238-248
Keywords Remote Sensing; Human Health; Adolescent; Adult; Body Mass Index; *Body Weight; Cross-Sectional Studies; Female; Health Surveys; Humans; Lighting/*statistics & numerical data; Middle Aged; Nigeria/epidemiology; Obesity/epidemiology; Overweight/*epidemiology; Prevalence; *Urbanization; Young Adult; *Bmi; *Nigeria; *Night light; *Obesity; *Overweight; *Urbanization
Abstract The prevalence of overweight and obesity are increasing in many African countries and hence becoming regional public health challenges. We employ satellite-based night light intensity data as a proxy for urbanization to investigate the relationship between urbanization and women's body weight. We use two rounds of the Demographic and Health Survey data from Nigeria. We employ both nonparametric and parametric estimation approaches that exploit both the cross-sectional and longitudinal variations in night light intensities. Our empirical analysis reveals nonlinear relationships between night light intensity and women's body weight measures. Doubling the sample's average level of night light intensity is associated with up to a ten percentage point increase in the probability of overweight. However, despite the generally positive relationship between night light intensity and women's body weight, the strength of the relationship varies across the assorted stages of night light intensity. Early stages of night light intensity are not significantly associated with women's body weight, while higher stages of nightlight intensities are associated with higher rates of overweight and obesity. Given that night lights are strong predictors of urbanization and related economic activities, our results hint at nonlinear relationships between various stages of urbanization and women's body weight.

Title Development of Solar Power Intelligent Street Lights System Type Journal Article
Year 2019 Publication International Journal of Scientific and Research Publications Abbreviated Journal
Volume 9 Issue 6 Pages
Keywords Lighting; Energy
Abstract The lack of natural light during night time in the urban environment has always been a problem. From people not being able to see where they are going, to the greater chance of being attacked or mugged at night which as we all know is a problem that has been in existence since humans started living together. The main advantage of this system exists in the reduction of costs related to energy consumption by the street light by integrating a vehicle/human detection algorithm into the system. The introduction of this vehicle/human detection algorithm further reduces the power consumption costs. In this project, solar PV is used to supply the energy to charge the battery. The battery later powers the operation of the whole system. The 12- 17V of the solar is buck to a steady 12V for battery charging. A light sensor is connected to the microcontroller that sense the light during day time, when the presence of day light is sensed the microcontroller turns ON the mosfet of the buck converter. If the voltage of the solar PV is greater than 12V, it charges the battery and switches off the load transistor. But at dawn, when the solar PV voltage is less than 12V the microcontroller turn OFF the buck converter mosfet and switch ON the load transistor. When no vehicle or human is detected for 10mins the microcontroller dims the LED lamp. If vehicle or human is detected the microcontroller brighten the LED lamp and inform the next microcontroller to brighten its LED lamp. If the next street light did not detect a vehicle or human after 10 mins it dims the lamp but if it detects a vehicle or human the lamp remain brightened. The microcontroller uses the ultrasonic sensor to detect object and the PIR sensor to detect human. The RF module is used for communication between the microcontrollers to inform each other the presence of vehicle or human.

Title Lighting for Heritage Building: A Case Study of the Lighting Design Applied on St. George’s Church in George Town, Penang Island Type Journal Article
Year 2020 Publication Awang M., Meor M Fared M. (eds) ICACE 2019. Lecture Notes in Civil Engineering Abbreviated Journal
Volume 59 Issue Pages 113-119
Keywords Lighting
Abstract Light is one of the critical aspects of architecture, yet it is one of the understated elements in our daily lives. Light has a significant spot to form events, activities, and memories. Scientific studies have shown that appropriate and proper lighting does not only affect human health but daily human moods as well. Nowadays, lighting fixtures play essential roles in architecture and markets. A proper lighting fixture helps to highlight the structure, textures, and form of the shape of a building. However, the designers tend to focus more on the art aesthetics rather than the conservation ethics, such as the colorful design and the attractive lighting fixtures on the building, while the prime concern should be on realizing the impact of the lighting fixture toward the environment. The objectives of this study are to highlight the issues of the lighting system of the heritage building and suggest some recommendations to meet the requirements for the heritage building for better lighting design. The data for this research was collected using the quantitative method. Thus, as a result, it is found out that lighting design highlights the historical building, and therefore, attracts tourists, which benefit the economy. However, improper lighting installation leads to a negative impact on the society and human health.

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.
