  • Relationship between biochars’ porosity and adsorption of three neutral herbicides from water

    The porous biochars have exhibited good adsorption to many organic pollutants, but the relationship between biochars’ porosity and their adsorption capacity is not clear at the moment. In this work, six biochars were produced from different feedstocks and under different pyrolysis conditions, and used for adsorption of three neutral herbicides from water. The results demonstrated that the ...

  • Optimization of atmospheric air plasma for degradation of organic dyes in wastewater

    This study optimises the degradation of a cocktail of the dyes methyl orange and bromothymol blue by atmospheric air plasma. Response surface methodology (RSM) was employed to investigate the efficacy of the plasma process parameters on degradation efficiency. A Box–Behnken design (BBD) was employed to optimise the degradation of dyes by air plasma discharge. A second order polynomial equation ...

  • Read about Confined Space in Construction and Atmospheric Testing Right Here!

    In 1993, 29 CFR 1910.146 went into effect as the first federal legislation governing entry into permit-required confined spaces in general industry. Because some industries, such as the construction industry, were covered by specific Occupational Safety and Health Administration (OSHA) safety regulations, they were exempt from the confined space entry requirements of the general industry rule. ...

  • Using the HydraProbe Soil Sensor for Determination of Flood Risk in the New York State Mesonet

    New York's Mesonet uses the HydraProbe and other meteorological sensors to help forecast flood hazards and climate. In January 2014, the Department of Homeland Security established the New York State Early Warning Weather Detection System. The centerpiece of the system is the New York State Mesonet, a network of 125 weather stations across the state, with at ...

  • Variability of GPS water vapor associated with warming activity in Peninsular Malaysia during the period of 2008–2011

    This study utilizes the precipitable water vapor (PWV) parameter retrieved from ground-based global positioning system (GPS) to detect warming activity in Peninsular Malaysia from 2008 to 2011. Daily average of GPS PWV and surface meteorology data taken from six selected stations over Peninsular Malaysia are analyzed. Prior to warming detection, GPS PWV results are compared with PWV obtained ...

  • Recent changes in patterns of western Canadian river flow and association with climatic drivers

    Climatic variability and change can have profound impacts on the hydrologic regime of a watershed, especially in regions that are sensitive to changes in climate, such as the northern latitudes and alpine-fed regions of western Canada. Quantifying historical spatial and temporal changes in hydrological data can provide useful information as to how water resources are affected by climatic and ...

  • Proposed Revisions to the Guideline on Air Quality Models (Appendix W)

    On July 14, 2015, the U.S. Environmental Protection Agency’s (U.S. EPA’s) Office of Air Quality Planning and Standards’ (OAQPS) Air Quality Modeling Group provided a pre-Federal Register (FR) publication of the proposed revisions to the Guideline on Air Quality Models (Appendix W to 40 CFR Part 51) (Guideline) on the U.S. EPA’s Support Center for Regulatory ...

  • Projected precipitation and air temperature over Europe using a performance-based selection method of CMIP5 GCMs

    An assessment of the plausible climate change in precipitation and surface air temperature (SAT) over the European region by the end of the 21st century is provided. The assessment is based on the results of output of the ocean–atmosphere models participating in the Coupled Model Intercomparison Project, phase 5 (CMIP5). Six climate models that best reproduce the historical behaviour of SAT ...

  • Variability of seasonal and annual rainfall in the River Nile riparian countries and possible linkages to ocean–atmosphere interactions

    Variability analyses for the rainfall over the Nile Basin have been confined mostly to sub-basins and the annual mean of the hydroclimatic variable based on observed short-term data from a few meteorological stations. In this paper, long-term country-wide rainfall over the period 1901–2011 was used to assess variability in the seasonal and annual rainfall volumes in all the River Nile ...

  • Tools for assessing sea level rise vulnerability

    Increasing sea level has the potential to place important infrastructure we rely on every day at risk, yet we lack good data to make decisions on what to do, when, and with what priority. The objectives of the research were to develop a method for estimating the time scales for various increments of sea level rise (SLR) throughout the 21st century, develop an accurate methodology for predicting ...

  • Ice Cream Freezing Using Nitrogen: How to Stay Safe while using Nitrogen

    Liquid nitrogen is a powerful and potentially dangerous form of nitrogen that freezes the water content of food and beverages within seconds. Ice cream manufacturers have developed new efficiencies in the ice cream freezing process by adopting liquid nitrogen to improve the workflow and quality of the finished product. Unfortunately, liquid nitrogen can actually be dangerous if it is not handled ...

  • Increase in mercury in Pacific yellowfin tuna

    Mercury is a toxic trace metal that can accumulate to levels that threaten human and environmental health. Models and empirical data suggest that humans are responsible for a great deal of the mercury actively cycling in the environment at present. Thus, one might predict that the concentration of mercury in fish should have increased dramatically since the Industrial Revolution. Evidence in ...
