The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • Model The Earth Shield From The Intense Solar Radiation

    SummaryIn this paper we will introduce the required powder to shield our earth and reducing the solar heat which will be intensified within the future. Three types of powder ‘Alumina, uranium, and Sand’ of various sizes ‘0-1000 um’ were involved in our mathematical model. Two types of shield were proposed, one around the earth and the alternative was around the sun. The Matlab program was ...


  • Non-Ionising Radiation

    Pressures on the environment may occur through chemical, physical and biological agents. The subject of this study is physical agents, where physical fields are examined. Physical fields are part of the natural environment. Depending upon their properties and the surrounding conditions, physical fields are transmitted through the spaces in which we live, potentially affecting human health and ...

  • Relating geo–meteorological parameters to global solar radiation for Egypt by Iranna–Bapat's estimation models

    Estimation of solar radiation is considered as the most important parameter for the design and development of various solar energy systems. But, the availability of the required data is very scarce and often not readily accessible. The foremost objective of the present study was to estimate the monthly average global solar radiation (GSR) at various locations for Egypt, by the generalised ...

  • Induction of thymine dimers by solar radiation in natural freshwater phytoplankton assemblages in Patagonia, Argentina

    Natural phytoplankton assemblages from a freshwater lake in Trelew (Province of Chubut, Patagonia, Argentina) were exposed to natural solar radiation at different depths in a water basin filled with fresh water rich in humic substances. Samples were taken at regular intervals for DNA extraction and subsequent analysis of DNA damage by determining the formation of thymine dimers using an ...

  • Multi-channel solar ultraviolet radiometer

    Solar ultraviolet radiation: The solar ultraviolet radiation reaching the ground is controlled by several factors, such as solar elevation, cloud cover, total ozone amount and ground reflection. A decrease in total ozone abundance is expected to lead to an increase in harmful UV radiation if all other factors are kept unchanged.  Cloudiness is among the largest sources of variance in the daily ...

  • Introduction to Solar Energy

    Solar energy refers to solar radiation energy. Since the formation of the earth, organism relies on the light and heat provide by the sun to survive. But nowadays, the application of solar energy has been widely paid attentions. In recent years, an increasing numbers of people pay more attention to it not because of its characteristics of the inexhaustible, but also ...

  • Free solar for Africa?

    The African continent is not homogeneous. The constant gap between the way we perceive the north of the continent and the harsh reality that the South is going through is often surprising. Many start to see and praise the "African miracle” progresses. However, many obstacles remain for Africa to impose its way. The sun, is a natural, free and abundant wealth in the African land, would it ...

  • Development of optimum solar irradiation energy model for Iran

    In this article, an optimal model for calculating the total solar irradiation is represented for Iran. Eight irradiation models are analysed based on the meteorology information of 22 synoptic stations. Afterwards, accuracy of these methods is compared using standard error criteria. Hence, Daneshyar and Modified Daneshyar are introduced as the most precise methods. Then, a new coefficient is ...

  • Solar Power 2011 - Solar PV Breaks Records in 2010

    Solar photovoltaic (PV) companies manufactured a record 24,000 megawatts of PV cells worldwide in 2010, more than doubling their 2009 output. Annual PV production has grown nearly 100-fold since 2000, when just 277 megawatts of cells were made.  Newly installed PV also set a record in 2010, as 16,600 megawatts were installed in more than 100 countries.  This brought the total worldwide ...

  • Solar thermal power coming to a boil

    After emerging in 2006 from 15 years of hibernation, the solar thermal power industry experienced a surge in 2007, with 100 megawatts of new capacity coming online worldwide. During the 1990s, cheap fossil fuels, combined with a loss of state and federal incentives, put a damper on solar thermal power development. However, recent increases in energy prices, escalating concerns about global ...

  • Rural electrification by photovoltaic solar energy in Algeria

    The economic and social development in Algeria in the last years has been in need of continues increasing in demand of electricity, especially in the isolated countryside. Solar energy represents a significant potential in Algeria, the country receives more than 3,000 hour of sunshine per year with a high level of radiation. The average of daily solar irradiation is from 5 to 7 kW hour m−2 the ...

  • Modelling and experimental verification of a solar reactor for photo-Fenton treatment

    In the present work, a novel design of a solar reactor is presented. This pilot plant scale reactor uses the UV-Visible and Near-Infrared solar radiation to promote the photo-Fenton treatment. A theoretical study and experimental verification were performed using formic acid as a model pollutant. The radiative transfer, thermal energy and mass balances equations were solved to compute the formic ...

  • Wastewater containing Cr(VI) treatment using solar tubular reactor

    The hexavalent chromium, Cr(VI), which is generated in the electroplating process, is toxic to most organisms and potentially harmful to human health. The method generally used for remediation of wastewater containing Cr(VI) employs chemicals with high toxicity. This work proposes an alternative technology for the treatment of these wastewaters, based on photochemical reduction of Cr(VI) by ...

  • Aplication of Solar Energy for Drying of Sludge from Pharmaceutical Industrial Waste Water and Probable Reuse

    Sludge, which is produced as a by-product of all treatment processes, has considerable potential as a fertilizer and soil conditioner. Many authorities now discharge the sludge after treatment directly to agricultural land in liquid form, while some others dewater and dry it first. In either case, with proper marketing, it is generally possible for an authority to earn revenue ...
