Deciphering the Code Do-it-yourselfers can buy inexpensive code readers that connect to this standardized onboard diagnostics (OBD) port and search for the code’s meaning on Web sites such as Engine Light Help. The Check Engine light can even be turned off by some code readers, even though this action alone does not actually repair the underlying problem. In many such cases the light will simply come back on later. In the 1600s, Ole Roemer became one of the first scientists to make a measurement of the speed of light. Roemer observed the orbits of Jupiter’s nearest moon and recognized that its orbital period was observed to be approximately 22 minutes longer when measured from Earth when it was furthest from Jupiter compared to when it was closest to Jupiter. Roemer reasoned that the difference was due to the fact that it took longer for light from Jupiter to travel the extra distance when Earth’s position was on the opposite side of the Sun from Jupiter. The distance d2 is 2.98×1011 m greater than the distance d1. Determine Roemer’s estimate of the speed of light in the 1600s. Measuring the effect of sky glow on a global scale is a complex procedure. The natural atmosphere is not completely dark, even in the absence of terrestrial sources of light and illumination from the Moon. This is caused by two main sources: airglow and scattered light. The Simons Cracking the Glass collaboration held a workshop on Oct 22-26, 2017 at Royaumont Abbey outside Paris, France. The intimate, focused workshop involved PIs, affillates, postdocs and students, with a goal of synthesizing progress, highlighting new discoveries with the potential to catalyze additional collaboration within the group, and coordinating future effort. Any scarcity of urban nighttime illumination was quickly diminishing as electrification spread across North American and Europe during the twentieth century, developing alongside urbanization and the growth of transportation networks (Isenstadt, 2014 Isenstadt, S. (2014). Good night. Places Journal. Retrieved 22 October, 2014, from https://placesjournal.org/article/good-night/[Crossref] [Google Scholar]). This proliferation of nighttime illumination has been continuous to the present day, save for two major disruptions: World War Two and the energy crisis of the 1970s. However, nighttime illumination efforts quickly resumed shortly after both of these events (Neumann, 2002b Neumann, D. (2002b). Architectural illumination since World War II. In D. Neumann (Ed.), Architecture of the night: The illuminated building (pp. 78–84). New York, NY: Prestel. [Google Scholar]). Current estimates are that artificial nighttime lighting continues to increase globally by about 3–6% annually (Hölker et al., 2010 Hölker, F., Moss, T., Griefahn, B., Kloas, W., Voigt, C., Henckel, D., … Tockner, K. (2010). The dark side of light: A transdisciplinary research agenda for light pollution policy. Ecology and Society, 15(4), 13.10.5751/ES-03685-150413[Crossref], [Web of Science ®] [Google Scholar]). This has been, in many ways, the ultimate realization of values strived for since the seventeenth century. A lengthening of the day has effectively been achieved, creating unmistakably modern nights where the various facets of nightlife can occur, and where many daytime activities can continue well into the night. But this has come with unintended consequences. In his exploration of ‘the world after dark’, Dewdney (2004 Dewdney, C. (2004). Acquainted with the night: Excursions through the world after dark. Toronto: HarperCollins Publishers Ltd. [Google Scholar], p. 101) cleverly evaluates the two-sided nature of this achievement, stating, i have problem with itel 1508 screen light problem Street light replacement project – We’re investing in a £25 million capital project to update and replace thousands of street lights across the town. i have problem with itel 1508 screen light problem The effectiveness of using full cutoff roadway lights to combat light pollution has also been called into question. According to design investigations, luminaires with full cutoff distributions (as opposed to cutoff or semi cutoff, compared here[87]) have to be closer together to meet the same light level, uniformity and glare requirements specified by the IESNA. These simulations optimized the height and spacing of the lights while constraining the overall design to meet the IESNA requirements, and then compared total uplight and energy consumption of different luminaire designs and powers. Cutoff designs performed better than full cutoff designs, and semi-cutoff performed better than either cutoff or full cutoff. This indicates that, in roadway installations, over-illumination or poor uniformity produced by full cutoff fixtures may be more detrimental than direct uplight created by fewer cutoff or semi-cutoff fixtures. Therefore, the overall performance of existing systems could be improved more by reducing the number of luminaires than by switching to full cutoff designs. A street light fault is classed as an emergency if the light’s wires are exposed, if the shade is broken or hanging off or if the problem is caused by a road traffic accident.  If you think the problem is an emergency, please call Contact Warrington on 01925 443322 and the team will aim to inspect the light within two hours. Please use the form below to report the street light problem. New LED streetlights have a small box on top of each column that flash a very small red and blue light. Please do not report any streetlights found to have these on, as this is to confirm that they are connected to our central management system. So while the fascination and allure of illuminations persist, darkness is today increasingly perceived as a rare and valuable commodity. This development could be regarded as a double paradigm shift from the dark night as a forbidding everyday occurrence that could only be lit up sporadically to its devaluation as an emblem of backwardness in the face of a new abundance of artificial light in the late 19th and early 20th centuries to its present valorization as a sought-after luxury in our densely populated and highly electrified world. (Hasenöhrl, 2014 Hasenöhrl, U. (2014). Lighting conflicts from a historical perspective. In J. Meier, U. Hasenöhrl, K. Krause, & M. Pottharst (Eds.), Urban lighting, light pollution, and society (pp. 105–124). New York, NY: Taylor & Francis. [Google Scholar], p. 119) Light pollution is a topic gaining importance and acceptance in environmental discourse. This concept provides a framework for categorizing the adverse effects of nighttime lighting, which advocacy groups and regulatory efforts are increasingly utilizing. However, the ethical significance of the concept has, thus far, received little critical reflection. In this paper, I analyze the moral implications of framing issues in nighttime lighting via the concept of light pollution. First, the moral and political importance of problem framing is discussed. Next, the origins and contemporary understandings of light pollution are presented. Finally, the normative limitations and practical ambiguities of light pollution are discussed, with the aim of strengthening the framework through which decisions about urban nighttime lighting strategies are increasingly approached. Dear sir, Good evening i want to know where the backlight settings that will make the key pad light to show on my Techno phone?. Prospective observers can report their results online by comparing the number of stars seen in the night sky with a set of template images that depict the stars’ visibility in varying levels of light pollution. Participation is open to anyone, anywhere in the world, who can get outside and look skyward. Concerns have also remained regarding the inverse of proliferating nighttime lighting, namely the rapidly declining access to a natural night sky in the developed world. In recent decades attempts to quantify skyglow and its global presence have emerged, however, data is still somewhat sparse. The first attempt to map this phenomenon on a global scale was published by Cinzano et al. (2001 Cinzano, P., Falchi, F., & Elvidge, C. D. (2001). The first world Atlas of the artificial night sky brightness. Monthly Notices of the Royal Astronomical Society, 328, 689–707.10.1046/j.1365-8711.2001.04882.x[Crossref], [Web of Science ®] [Google Scholar]). A more recent study by Gallaway et al. (2010 Gallaway, T., Olsen, R., & Mitchell, D. (2010). The economics of global light pollution. Ecological Economics, 69, 658–665.10.1016/j.ecolecon.2009.10.003[Crossref], [Web of Science ®] [Google Scholar]) built on their findings and concluded that the amount of people living in areas with a ‘polluted night sky’ is extremely high: around 99% in both North America and the European Union.88. Gallaway et al. (2010 Gallaway, T., Olsen, R., & Mitchell, D. (2010). The economics of global light pollution. Ecological Economics, 69, 658–665.10.1016/j.ecolecon.2009.10.003[Crossref], [Web of Science ®] [Google Scholar]) utilize the threshold criteria established by Cinzano et al. (2001 Cinzano, P., Falchi, F., & Elvidge, C. D. (2001). The first world Atlas of the artificial night sky brightness. Monthly Notices of the Royal Astronomical Society, 328, 689–707.10.1046/j.1365-8711.2001.04882.x[Crossref], [Web of Science ®] [Google Scholar]) for considering an area ‘polluted’ by light. These criteria ‘consider the night sky polluted when the artificial brightness of the sky is greater than 10% of the natural sky brightness above 45° of elevation’ (Gallaway et al., 2010 Gallaway, T., Olsen, R., & Mitchell, D. (2010). The economics of global light pollution. Ecological Economics, 69, 658–665.10.1016/j.ecolecon.2009.10.003[Crossref], [Web of Science ®] [Google Scholar], p. 660).View all notes Furthermore, on both continents approximately 70% of the population lives in areas where brightness at night is at least three times natural levels. From a dark rural area, our unaided eyes can normally see up to 3,000 stars; people with strong eyesight can even see close to 7,000 stars. However, in many urban areas today this number is reduced to around 50, or perhaps even less (Mizon, 2012 Mizon, B. (2012). Light pollution: Responses and remedies (2nd ed.). New York, NY: Springer.10.1007/978-1-4614-3822-9[Crossref] [Google Scholar]). Researchers caution that if the current pace of increasing brightness continues, the ‘pristine night sky’ could become ‘extinct’ in the continental United States by 2025 (Fischer, 2011 Fischer, A. (2011). Starry night. Places Journal. Retrieved 22 October, 2014,. from https://placesjournal.org/article/starry-night/[Crossref] [Google Scholar]).
