  • Effect of sodium azide on the metabolic activity of cultured fetal cells

    Sodium azide is a highly toxic substance. However, the mechanism of its toxicity has not been fully established. In the present study, we attempted to investigate the toxicity of sodium azide in various cultured fetal cells, using changes in cellular respiration as an indicator of metabolic inhibition to elucidate tissue-specificity. The human fetal cell lines used in this study included ...

  • Green synthesis of ZnSe quantum dots using in-situ synthesised sodium selenide

    Single-step green synthesis of zinc blende ZnSe quantum dots (QDs) is performed using sodium selenide and zinc stearate. The present method is non-toxic and is considered reasonably green route where stearate ions released during the reaction act as surfactant. The size quantisation effect is revealed by blue shifted absorption bands with a band-gap energy of ~2.9 eV with respect to bulk ZnSe ...

  • Development of one-dimensional computer code DESOPT for thermal hydraulic design of sodium-heated once through steam generators

    Once-through Steam Generator (SG) is a critical component of Liquid Metal Fast Breeder Reactor (LMFBR) plant. It is a counter current heat exchanger, in which heat is transferred from the hot sodium flowing on the shell side to water/steam in tube side. High pressure subcooled water enters the SG tube from bottom, gets heated up to saturation, goes through nucleate boiling, dry out and post dry ...

  • Chemical Tank volume measurement

    In this application, Pulsar equipment replaced other ultrasonic gear which was not coping with the multiple echoes coming from a dome top tank. Level Star 110 non-contacting ultrasonic level measurement was supplied to a major chemical manufacturer, resolving a problem they had in the effective gauging of Sodium hydroxide. The Pulsar equipment replaced ultrasonic equipment previously supplied by ...

  • Chlorine Theory & Measurement

    Chlorine, dissolved in liquid is one of the most effective and economical semi-killers for the treatment of water to make it potable or safe to drink. Chlorine's powerful disinfectant qualities come from its ability to bond with and destroy the outer surfaces of bacteria and viruses. Drinking water chlorination is one of the most widely used methods to safeguard chinking water supplies. In ...

  • Conductivity Theory and Measurement

    Electrical conductivity is a measure of the ability of a solution to cany* a current. Current flow in liquids differs from mat in metal conductors in that electrons cannot flow freely, but must be carried by ions. Ions are formed when a solid such as salt is dissolved in a liquid to form electrical components having opposite electrical charges. For example, sodium chloride separates to form Na" ...

  • Measurement of TOC in High-Salt Sample

    The quantity of organic matter in seawater is important in the research and monitoring of marine pollution as an indicator of organic pollution. The salt content in seawater is typically about 3.5 %, but using the Shimadzu total organic carbon analyzer, it is possible to measure the TOC directly without dilution or other pretreatment procedures. Here, we introduce an example of measurement of ...

  • Daphne Utilities, Alabama, Enjoys More Than Seven Years of On-Site Sodium Hypochlorite Production from Process Solutions, Inc. Microclor System

    Located along the eastern shore of Mobile Bay, scenic Daphne, Alabama boasts one of the most proactive and progressive utilities in the country. Daphne Utilities which operates the gas, water and wastewater systems for the area’s roughly 20,000 inhabitants has been winning awards for excellence since its founding in 1953. In late 2007, the utility embarked on the design of a new water plant ...

  • How can I measure Salt in food?

    Sodium is a mineral required by the body for normal functions, but excessive intake can cause high blood pressure and hypertension. This has lead governments and regulatory bodies to focus on monitoring the levels of salt in foods in order to reduce the risk of these health affects. Canned foods are of particular concern as these often contain relatively high levels of salt. ...

  • Emulsion-Breaking Techniques for Accurate Oil in Water Measurements

    A White Paper discusses emulsion-breaking techniques for ensuring accurate oil in water measurements. Certain water samples, such as those containing detergent, may form an emulsion when oil in water extraction into a solvent is done. In order to ensure an accurate measurement, the emulsion must be broken. Six techniques are described that can be used for reducing an emulsion ...

  • Eutrophication of Waters, Role of Phosphates, Preventive Measures - Phosphates and Alternative Detergent Builders

    Recognition of the relationship between increasing phosphorus inputs to surface waters and the subsequent increase in eutrophication of water bodies gave rise to public concern during the 1970’s and 1980’s. This led to action by several countries including the USA, Japan and some EU member states, to reduce phosphorus loads, particularly from urban and industrial point sources. The two main areas ...
