The problem of phosphorus pollution and its resource utilization has been a source general concern. preparation green, renewable, non-secondary adsorbents become research direction. In this paper, one-step hydrothermal method Ca-modified magnetic sludge biochar (Ca-MSBC) is used for enhancing phosphate removal. results show that the adsorption rate by Ca-MSBC mainly controlled chemisorption but...

Software is an integration of numerous programming modules  (e.g., functions, procedures, legacy system, reusable components, etc.) tested and combined to build the entire module. However, some undesired faults may occur due a change in modules while performing validation verification. Retesting software costly affair terms money time. Therefore, avoid retesting of entire&...

This study presents a modified and conceptually simple step-by-step decoding algorithm for binary cyclic BCH codes. Step-by-step decoding temporarily changes one information bit value at a time and then checks weather the weight of the error pattern decreases by computing the corresponding syndrome matrix determinant. Based on the channel information, this study propose a modified step-by-step ...

in this paper wave transformation in a submerged sloped breakwater and its hydraulic performance was simulated by developing a numerical model in fortran. the code was established by combining porous flow and a two-phase model using vof method. modified navier-stokes and k-ε equations implemented to the model to simulate the flow in porous media. cut cell method was modified to simulate fluid t...

The synthesis of mesoporous CuFe2O4 spinel by several nanocasting strategies (i.e., multi-step nanocasting, one step nanocasting, modified solid-liquid), in which copper and iron nitrates are used as precursors and Pluronic P123 as surfactant, is explored. We have also checked the effect of pH, citric acid and sodium citrate in multi-step nanocasting method. The modified solid-liquid method whi...

the electrocatalytic oxidation of captopril (cap) was studied by modified carbon nanotubes paste electrode in the presence of isoproterenol (ispt) using cyclic voltammetry (cv), chronoamperometry and square wave voltammetry (swv). also, the values of catalytic rate constant (k), and electron transfer coefficient (α) for cap were calculated. the mechanism of ca electrochemical behavior at the mo...
