Rivers are important as the main source of supply for drinking, agriculture and industry.However, drinking water quality in terms of qualitative parameters, is the most important variable. Studias and predicting  changes in quality parameters along a river, are one of the goals of water resources planners and managers. In this regard, many water quality models in order to maintain better water ...

Time Delay Spectrometry (TDS) is a technique used to measure both frequency and time responses of acoustic and electrical systems. TDS theory is presented in both intuitive and mathematical terms. The theoretical limitations of current TDS technology are described. A new extension to TDS theory is introduced which has the potential to signiicantly improve TDS measurements. Implementation issues...

Incineration is a widely used and well established technology for the municipal solid waste (MSW) management. Modern MSW incineration plants are equipped with improved air pollution control (APC) systems, which reduce pollutants well below the established limits. The environmental concern has, thus, moved from the air emissions to the solid residues generated from the APC systems of the inciner...

dl-Norvaline is a molecular crystal at room temperature and it undergoes a phase transition when cooled below 190 K. This phase transition is believed to be Martensitic, thus making it of particular interest for molecular machines. In this paper we investigate this phase transition by measuring its terahertz (THz) spectrum over a range of temperatures. Temperature-dependent THz time-domain spec...

Recent amendment on the Food Sanitation Act in Korea mandated the Minister of Food & Drug Safety to secure the scientific basis for management and reevaluation of standards and specifications of foods. Especially because the current food safety control is limited within the scope of 'Farm to Market' covering from production to retail in Korea, safety control at the plane of true 'Farm to Fork' ...

Abstract Desalination of seawater is a promising response to solving the lack drinkable water. The separation cations and anions carried out by inserting desalination cell in middle novel design photoelectrocatalytic (PEDC). Different parameters were evaluated optimized for increasing capability system desalt hypersaline Ultraviolet illumination (UV) was used as driving force, exciting coated t...

Optimization of the acid leaching process for Mongolian apatite-based ore containing rare-earth elements (REEs) was studied. The ore contained approximately 10% of REEs as total rare earth oxides, and the major impurities were Ca (33% as CaO) and Fe (23% as Fe2O3). Fe bearing minerals could be removed by passing the sample through a wet high-intensity magnetic separator before leaching. After m...

Tardive syndrome (TDS) is a potentially permanent and irreversible hyperkinetic movement disorder caused by exposure to dopamine receptor blocking agents. Guidelines published by the American Academy of Neurology recommend pharmacological first-line treatment for TDS with clonazepam (level B), ginkgo biloba (level B), amantadine (level C), and tetrabenazine (level C). Recently, a class II study...
