Taschenbuch. Condizione: Neu. Druck auf Anfrage Neuware - Printed after ordering - Research Paper (postgraduate) from the year 2016 in the subject Engineering - Chemical Engineering, grade: A, Andhra University (College of Engineering), course: Chemical Engineering, language: English, abstract: The aim of the present study is to optimize and model the removal of Two Azo and Two Anthra-Quinone Dyes from the dye effluent using Tunic of Allium cepa derived activated carbon using RSM. The relationship between dye removal efficiency and three main independent parameters including Temperature, Solution pH and Adsorbent Dosage were evaluated by applying central composite design (CCD) and Box-Behnken design (BBD).Water Has the high importance in industrial ad domestic areas, Where Industries consume a lot of water and releases highly toxic effluents which are really harmful to the environment containing the toxic metals like Cr, Cd, Pd, Ti, Zn and many harmful dyes etc. Textile effluent dyes are targeted I the present work which exist in two forms (i) True Color (ii) Apparent color. There are various dyes used in the textile industries among which majority of dye stuffs are majorly based on azodyes which are used to dye cotton fabric and anthra-quinone dyes.Azo Dyes: Determination of azo dyes are categorized by the presence of (-N=N-) azo group as chromophore. Azo dyes are generally found in synthetic dye classes. Previously azo dyes were applied to cotton which involves the reactions with chemical components which reacts to form the dye into the fiber or on the surface. Primuline red and Para red fall into this group of azo dyes introduces in 1880's.Azo dyes are mostly used in cotton fabric.Anthra- quinone dyes: Determination of anthra- quinone dyes are characterized by carbonyl group (>C=O) as chromophore. Other names of anthra- quinone are anthrachinon, dioxoanthracene and different trade names like Corbit and Hoelite. The dyes like Saffranin, indigo carmine, Alizarin, Red S, Crystal violet were chosen here from the textile effluent for the removal.The source materials used here are natural powders namely Tunic of Allium cepa and its activated carbon.…

Condizione: Hervorragend. Zustand: Hervorragend | Sprache: Französisch | Produktart: Bücher | L'algorithme d'échange de clés Diffie-Hellman (D-H) a été développé pour échanger des clés secrètes par des canaux non protégés. L'algorithme D-H a été modifié en un protocole interactif de preuve à connaissance nulle. Ce protocole a été appliqué à de nombreux protocoles de sécurité, notamment le protocole SSL (Security Sockets Layer), le protocole SSH (Secure Shell) et le protocole IP Sec.…

Condizione: Hervorragend. Zustand: Hervorragend | Sprache: Deutsch | Produktart: Bücher | Der Diffie-Hellman-Schlüsselaustauschalgorithmus (D-H) wurde entwickelt, um geheime Schlüssel über ungeschützte Kanäle auszutauschen. Der D-H-Algorithmus wurde zu einem interaktiven Zero-Knowledge-Proof-Protokoll modifiziert. Das vorgeschlagene Protokoll ist so konzipiert, dass es die Zero-Knowledge-Proof-Eigenschaften erfüllt und den bekannten Angriffen standhält. Dieses Protokoll wurde auf viele Sicherheitsprotokolle angewendet, darunter Security Sockets Layer (SSL), Secure Shell (SSH) und IP Sec.…
