Artificial night lighting inhibits feeding in moths.
One major, yet poorly studied, change in the environment is nocturnal light pollution, which strongly alters habitats of nocturnally active species. Artificial night lighting is often considered as driving force behind rapid moth population declines in severely illuminated countries. To understand these declines, the question remains whether artificial light causes only increased mortality or a...
متن کاملArtificial Lighting Interference on Free Space Photoelectric Systems
Artificial lighting is a main source of interference on free space photoelectric systems for communication applications. This work presents digital measurements and numerical analysis of the time and frequency characteristics of artificial lighting interference using Welch Power Spectral Density estimate and spectrogram with Short Time Fourier Transform. Measurements of time waveforms and spect...
متن کاملEconomic Evaluation of Artificial Lighting in Vegetable Greenhouses (Case Study: Cucumber Production in Hamadan Province)
Sunlight, as a natural resource, is an important factor in agriculture, which is supplied indefinitely and without any charge by the sun. But some phenomena such as cloudy weather or shortening the length of the day throughout the year, cause restrictions on access to this important source. This is very important for cultivation in controlled environments such as greenhouses, which usually prod...
متن کاملLighting programme and iranian schools lighting requirements
It is accepted that the visual comfort in schools depends on the quality of the whole visual environment. This leads to the concern upon the quality and quantity of lighting. Currently in Iran, in order to calculate energy transfer for public buildings a coefficient is usually used. This coefficient considers the rate of sunlight energy absorption in these kinds of buildings. To increase the ...
