  • Positioning activated carbon amendment technologies in a novel framework for sediment management

    Contaminated sediments can pose serious threats to human health and the environment by acting as a source of toxic chemicals. The amendment of contaminated sediments with strong sorbents like activated carbon (AC) is a rapidly developing strategy to manage contaminated sediments. To date, a great deal of attention has been paid to the technical and ecological features and implications of ...

  • Passive sampling methods for contaminated sediments: State of the science for metals

    It is generally accepted that “dissolved” concentrations of contaminants in sediment pore water (Cfree) provide a more relevant exposure metric for risk assessment than do total concentrations. Passive sampling methods (PSMs) for estimating Cfree offer the potential for cost‐efficient and accurate in situ characterization of Cfree for inorganic sediment contaminants. In contrast to the PSMs ...

  • Passive sampling methods for contaminated sediments: Practical guidance for selection, calibration, and implementation

    This manuscript provides practical guidance on the use of passive sampling methods (PSMs) that target the freely dissolved concentration (Cfree) for improved exposure assessment of hydrophobic organic chemicals in sediments. Primary considerations for selecting a PSM for a specific application include clear delineation of measurement goals for Cfree, whether laboratory‐based “ex‐situ” and/or ...

  • Requirements for successful implementation of total quality management

    This paper presents some of the key findings of a study into quality management practices of a number of Australian manufacturers with a known interest in and commitment to quality improvements. The information was derived from a detailed questionnaire completed by 52 organisations, and three in-depth case studies. Based on the analysis of the questionnaire survey and the case studies, this paper ...

  • Seropédica landfill

    The Seropédica landfill is located on the outskirts of Rio de Janeiro. Since the closure of the 130-hectare big Gramacho landfill, Seropédica now receives over 6,000 tons of waste per day. Seropédica is the most modern solid waste treatment center in Brazil and Hofstetter has been awarded the biogas treatment process, as well as the set up of a flaring system at the landfill. ...

  • How one small change could reduce your food waste

    We often don’t give much attention to the food we consume. Grabbing a bite on the go or chowing down a meal are automatic actions based largely on appealing flavors and rumbles in our stomachs. Similarly, we often don’t give much attention to the food we waste — which, annually, weighs close to 4.5 times the combined weight of every human being on the planet. When we waste food, ...

  • Magnetic Water Conditioner

    I am sure you have heard about hard water before, and also know that hard water is bad for our health. If you check the kettle for boiling water, you will see limescale which will affect the efficiency of energy. There are several solutions for water softening, especially to lower the calcium and magnesium in water. 1. The easiest way is just to boil the water, the calcium hydroxide and magnesium ...

  • Differential histone H3 Lys-9 and Lys-27 methylation profiles on the X chromosome

    Histone H3 tail modifications are among the earliest chromatin changes in the X-chromosome inactivation process. In this study we investigated the relative profiles of two important repressive marks on the X chromosome: methylation of H3 lysine 9 (K9) and 27 (K27). We found that both H3K9 dimethylation and K27 trimethylation characterize the inactive X in somatic cells and that their relative ...

  • International water sharing: examining the Montana–Alberta dispute in the context of the century-old Boundary Waters Treaty

    The Boundary Waters Treaty of 1909 set out the terms and conditions by which citizens in Canada and the United States would be permitted to access and use trans-national surface water resources. In 2003, the Governor of Montana claimed that Montanans were not receiving their collective entitlement of the boundary waters that flowed into Alberta and requested the International Joint Commission ...

  • Influence of permeation on air/water cleaning of spiral wound membrane NF/RO elements

    To improve hydraulic conditions, periodic air/water cleaning (AWC) is applied to a nanofiltration (NF) spiral wound membrane (SWM) element under permeation conditions to control biofouling and particulate fouling. A pilot study was carried out for 212 days with a vertically positioned SWM element fed by tap water enriched with a biodegradable compound (60 μg acetate-C l−1). Operational parameters ...

  • Water recovery from sewage using forward osmosis

    This research is part of the Sewer Mining project aimed at developing a new technological concept by extracting water from sewage by means of forward osmosis (FO). FO, in combination with a reconcentration system, e.g. reverse osmosis (RO) is used to recover high-quality water. Furthermore, the subsequent concentrated sewage (containing an inherent energy content) can be converted into a ...

  • Designing a constructed wetland for the detention of agricultural runoff for water quality improvement

    Received for publication December 18, 2008. The goal of this study was to construct a wetland that would detain runoff from a 162-ha watershed for the purposes of improving water quality. The volume of runoff that needed to be detained was determined to be that amount coming off the 162-ha watershed consisting of 146 ha of cultivated crop land and 16 ha of pasture that exceeded the amount that ...

  • In vitro biotransformation rates in fish liver S9: Effect of dosing techniques

    In vitro biotransformation assays are currently being explored to improve estimates of bioconcentration factors of potentially bioaccumulative organic chemicals in fish. This study compares thin‐film and solvent‐delivery dosing techniques, as well as single vs. multiple chemical dosing for measuring biotransformation rates of selected polycyclic aromatic hydrocarbons in rainbow trout ...

  • Using magnets to cater energy requirements

    It is safe to say that it is conceivable to utilize magnets for vitality? Yes, not just is it conceivable it has been utilized for a considerable length of time. In the late 1800s they were utilizing this strategy for force. It has created a ton since that time and gets to be exceptionally questionable yet yes utilizing magnets for vitality is completely ...

  • How to Safely Use Neodymium Countersunk Magnets

    Neodymium countersunk magnets are magnets shaped like rings with a hole in the middle. Their magnetic force is very strong despite the size of the magnet. They are known to be five to seven times stronger than ceramic (hard ferrite) magnets.  The countersunk neodymium magnets have many domestic and commercial uses.  They can only work with countersunk screws as they are very brittle ...

  • How Does Global Warming Affect World Hunger?

    You may have heard the argument from disillusion people that either there is nothing that can be done about global warming, or that it simply doesn’t exist. Global warming is a fact, and it is also a fact that we as humans are the cause. Not a partial or major cause, but the end all be all of reasons the earth’s temperatures are rising. You may have heard from someone that global ...
