A predictive model for the formation potential of dichloroacetamide, a nitrogenous disinfection by-product formed during chlorination

Precursors of dichloroacetamide, an emerging nitrogenous DBP formed during chlorination or chloramination.

Haloacetamides (HAcAms) are an emerging class of nitrogenous disinfection byproducts (N-DBPs). However, there is a limited understanding about the precursors of HAcAms. In this study, we screened the precursors of dichloroacetamide (DCAcAm), the most commonly identified HAcAm in chlorinated or chloraminated drinking water. DCAcAm formation potential (FP) of raw water samples collected in differ...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

a study on insurer solvency by panel data model: the case of iranian insurance market

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.

Nitrogenous Disinfection By-Product Occurrence, Formation and Stability in Drinking Water

the effects of water ozonation on disinfection by-product formation

background : the aim of this study was to evaluate the performance of water ozonation on disinfection by-product formation. methods : experiments were carried out on samples taken from tajan river, mazandaran province, iran. samples of the pre-filtered raw water and from the 3.5-l water tank reservoir (wt) were analyzed for uv-254 absorbance, dissolved organic carbon (doc), hs and non-hs, chlor...
