Title The Heavens: An Illustrated Handbook of Popular Astronomy Type Book Whole
Year 1867 Publication Abbreviated Journal
Volume Issue Pages (up)
Keywords Skyglow
Abstract Relevant excerpt: In large towns, the thousands of gas-lamps or other lights render the observation of the Zodiacal Light very difficult, not to say impossible, at all times. On the other hand, in stations conveniently situated, it can be seen at the various epochs of the year, even in the temperate zones.

Title Effects of Light-at-Night on the Rat Liver – A Role for the Autonomic Nervous System Type Journal Article
Year 2019 Publication Frontiers in Neuroscience Abbreviated Journal Front. Neurosci.
Volume 13 Issue Pages (up)
Keywords Animals
Abstract Exposure to light at night (LAN) has been associated with serious pathologies, including obesity, diabetes and cancer. Recently we showed that 2 h of LAN impaired glucose tolerance in rats. Several studies have suggested that the autonomic nervous system (ANS) plays an important role in communicating these acute effects of LAN to the periphery. Here, we investigated the acute effects of LAN on the liver transcriptome of male Wistar rats. Expression levels of individual genes were not markedly affected by LAN, nevertheless pathway analysis revealed clustered changes in a number of endocrine pathways. Subsequently, we used selective hepatic denervations [sympathetic (Sx), parasympathetic (Px), total (Tx, i.e., Sx plus Px), sham] to investigate the involvement of the ANS in the effects observed. Surgical removal of the sympathetic or parasympathetic hepatic branches of the ANS resulted in many, but small changes in the liver transcriptome, including a pathway involved with circadian clock regulation, but it clearly separated the four denervation groups. On the other hand, analysis of the liver metabolome was not able to separate the denervation groups, and only 6 out of 78 metabolites were significantly up- or downregulated after denervations. Finally, removal of the sympathetic and parasympathetic hepatic nerves combined with LAN exposure clearly modulated the effects of LAN on the liver transcriptome, but left most endocrine pathways unaffected.

Title Impacts on Human & Environment of Night Time Light Pollution Type Journal Article
Year 2019 Publication Galore International Journal of Applied Sciences and Humanities Abbreviated Journal
Volume 3 Issue 2 Pages (up)
Keywords Human Health; Ecology; Review
Abstract Light is chief source of human life. Humans are too much depended on light. High amount of use light are causing pollution to be a growing problem, however few research studies have addressed probable effects of light pollution on wildlife& humans. Astrophysicists consider light pollution to be a growing problem on worldwide. The night-sky illumination is originated to be effected by human factors such as land utilization and population density of the observation sites, together with meteorological and/or environmental factors. The interest in light pollution has been growing in many fields of science, extending from the traditional field of astronomy to atmospheric physics, environmental sciences, natural sciences and human sciences.

Title Light Pollution at Mount Wilson: The Effects of Population Growth and Air Pollution Type Journal Article
Year 2000 Publication Memorie della Società Astronomia Italiana Abbreviated Journal
Volume 71 Issue 1 Pages (up)
Keywords Skyglow
Abstract This is the first part of a study of the historical growth of light pollution at Mount Wilson Observatory. The night sky brightness at Mount Wilson due to light pollution from Los Angeles basin was calculated for the years 1910 to 1990, neglecting changes in lighting technology, and without any air pollution ('smog'). The very large effect of population growth is shown. We made a simple extension of our night sky brightness program to include a layer of smog. Two possibilities of constant density and finite thickness. The ground level density is determined by the visibility. We assume a smog layer whose density increases from zero in 1920 to appropriate values for the years from 1950. We added this layer to out model and repeated the Mount Wilson calculations. An average smog layer reduces the visual brightness at the present time by about 6 percent.

Title Informal Economy and Remittance Estimates of India Using Nighttime Imagery Type Journal Article
Year 2010 Publication International Journal of Ecological Economics & Statistics Abbreviated Journal
Volume 17 Issue Pages (up)
Keywords Remote Sensing; Economics
Abstract Accurate estimates of the magnitude and spatial distribution of both formal and informal economic activity have many useful applications. Developing alternative methods for making estimates of these economic activities may prove to be useful when other measures are of suspect accuracy or unavailable. This research explores the potential for estimating the formal and informal economy for India using known relationships between the spatial patterns of nighttime satellite imagery and economic activity in the United States (U.S.). Regression models have been developed between spatial patterns of nighttime imagery and Adjusted Official Gross State Product (AGSP) for the states of the U.S. The slope and intercept parameters derived from the regression models of the U.S. were blindly applied to India, resulting in an underestimation of Gross State Income (GSI) for each state and Union Territory (UT) of India because of the lower level of urbanization in India in comparison to the U.S. However, a comparison of estimated GSI from the nighttime lights image and the official Gross State Product (GSP) of the states and UTs of India indicates a high correlation between them (r = 0.93). The different levels of urbanization (i.e. percent of population in urban areas) in the U.S. and India are used to adjust the Estimated Gross Domestic Income (EGDI) by multiplying by the ratio of the percentage of the population in urban areas for the two countries. This gives the Adjusted Estimated Gross Domestic Income of India (AEGDI), which is compared with the official Gross National Income (GNI) estimates of India’s states and UTs. The results suggest that the magnitude of India’s informal economy and the inflow of remittances are 150 percent larger than their existing official estimates in the GNI.
