The Influence Of Transition Metal Ions On The Kinetics Of Ascorbic Acid Oxidation By Methylene Blue In Strongly Acidic Media, M. Nasiruddin Khan, Anila Sarwar

Turkish Journal of Chemistry

The kinetics of the oxidation of L-ascorbic acid (H_{2} A) by methylene blue was investigated in strongly acidic media over the temperature range 22-40 ^oC. The kinetic studies were carried out as a function of different variables like concentration, pH, ionic strength and temperature. The rate was found to be a linear relation with [H_{2} A], [M.B.] and [H^{+}]. Ionic strength dependence formation indicated complex formation by monocationic and anionic species in solution. The reaction rate was greatly catalyzed by the presence of trace amounts of copper (II) ion. Possible mechanisms for the catalyzed and uncatalyzed reactions are proposed. Kinetic …

Conductimetric And Potentiometric Titration Of Some Hydroxylated Cinnamic Acids With Tetrabutylammonium Hydroxide In Non-Aqueous Media, A.Hakan Aktaş, Gülsüm Yaşar, Güleren Özkan Alsancak, Şahi̇nde Demi̇rci̇

Turkish Journal of Chemistry

In this study, four hydroxycinnamic acids, namely 3,4-dihydroxycinnamic acid, 4-hydroxycinnamic acid, 4-hydroxy --3- methoxycinnamic acid and 4-hydroxy-3,5-dimethoxycinnamic acid, were titrated conductimetrically and potentiometrically using triethylamine and tetrabutylammonium hydroxide in acetonitrile, 2-propanol, and pyridine solvents under a nitrogen atmosphere at 25 ^oC. In conductimetric titration with tetrabutylammonium hydroxide all of the compounds exhibited conventional stoichiometric titration curves in 2-propanol . As is evident from the titration curves, all these compounds gave two well-defined end points. The first end point corresponds to exactly one equivalent and the second one to the two equivalents of the base. In conductimetric titration with tetrabutylammonium hydroxide, …

New Photochemical And Electrochemical Methods For The Degradation Of Pesticides In Aqueous Media. Environmental Applications, J. J. Aaron, Mehmet A. Oturan

Turkish Journal of Chemistry

The development of new electrochemical and photochemical methods for the decontamination of natural water containing significant concentrations of aromatic pesticides is described. The electrochemical method is based on the electro-Fenton process, i.e. the simultaneous reduction of O_{2} and Fe^{3+} ions. Hydroxyl (OH^{.}) radicals are electrosynthesized in aqueous solutions, followed by complete mineralization of the initial pollutants. The photochemical methods involve either a direct photodegradation reaction of pesticides by UV light, or indirect photodegradation processes including H_{2}O_{2} photolysis or photo-Fenton reagents (H_{2}O_{2}/ Fe^{3+} ). Examples of the application of these methods to chlorophenoxy acid herbicides and four aromatic pesticides (bendiocarb, pirimiphos-methyl, …

Electronic Resources: A Wolf In Sheep’S Clothing?, Bradley L. Schaffner

Staff and Faculty Work

This article examines the impact of electronic technology on libraries and scholarship. It focuses on some of the challenges of using electronic resources in research libraries, which include the cost of acquiring electronic formats and the effect that such expenditures have on other library services and collection development practices. The article also explores how electronic resources have changed the way students and scholars conduct research. The goal of this essay is not to criticize or condemn electronic formats but, rather, to illustrate that electronic technology is simply one tool, among others, for the dissemination of information. As such, electronic resources …

Florida Commission On Mental Health & Substance Abuse Final Report, Florida Commission On Mental Health & Substance Abuse

FMHI Publications

The Florida Commission on Mental Health and Substance Abuse was created in 1999 to conduct a systematic review of the state’s mental health and substance abuse system. The Commission was asked to make recommendations in areas including planning, service strategies, funding, accountability, emergency behavioral health services, and the unique needs of older persons.

Twenty-three Commissioners from throughout Florida were appointed by the governor and the legislature to broadly represent the key constituencies in mental health and substance abuse. Four workgroups were formed to examine and report on special issues including: 1) information needs and technology; 2) children’s; 3) adults’; and …

Gender Mainstreaming In Legal And Constitutional Affairs: A Reference Manual For Governments And Other Stakeholders, Christine Chinkin

This is one of the sectoral guides that are part of the Gender Management System (GMS) resource kit, a series of publications presenting GMS. GMS is an innovative system developed by the Commonwealth Secretariat for gender mainstreaming. The system is a comprehensive network of structures, mechanisms and processes for bringing a gender perspective to bear on all government policies, plans, programmes and projects. The kit consists of a handbook which presents the GMS in detail; sectoral guides to gender mainstreaming in specific sectors; and resource documents to assist the user in gender analysis, monitoring, evaluation and other aspects of gender …

Private Philanthropy And The Economics Of Public Radio, Arthur C. Brooks

Center for Policy Research

Public radio in the United States receives both direct and indirect government funding. Direct subsidies come in the form of lump-sum and matching grants, while indirect subsidies proceed from tax revenues foregone on deductible private donations. Each of these sources of government money impacts charitable giving to public radio. This paper estimates both of these effects, using data on a national sample of public radio stations in the United States from 1990-96. I find that public funding to stations has a positive impact on private giving, but this impact rapidly decreases as the level of government subsidies increases, ultimately becoming …

Can Policy Changes Be Treated As Natural Experiments? Evidence From State Excise Taxes, Jeffrey D. Kubik, John R. Moran

Center for Policy Research

An important issue in public policy analysis is the potential endogeneity of the policies under study. If policy changes constitute responses on the part of political decision-makers to changes in a variable of interest, then standard analyses that treat policy changes as natural experiments may yield biased estimates of the impact of the policy (Besley and Case 2000). We examine the extent to which such political endogeneity biases conventional fixed effects estimates of behavioral parameters by identifying the elasticities of demand for cigarettes and beer using the timing of state legislative elections as an instrument for changes in state excise …

Numerical Simulation Of A Gas–Liquid Flow In A Fixed Bed, Ashok S. Sangani, Sangkyun Koo

Biomedical and Chemical Engineering - All Scholarship

A countercurrent gas–liquid flow through a fixed bed of spherical particles is examined numerically by solving the particle-scale equations governing the gas and liquid flows. The liquid is assumed to flow along the surface of the particles forming a thin film. The case of small gas flow rates is examined in detail first. In this limit the presence of the liquid film increases the gas pressure drop over its value for a dry bed by three mechanisms: The liquid film makes the apparent size of the particles larger, decreases the pore space for the gas flow, and, with its velocity …

Spatial And Temporal Distribution Of Tsetse Fly Trap Catches At Nguruman, Southwest Kenya, A. Odulaja, J. Baumgärtner, S. Mihok, I. M. Abu-Zinid

All Peer-Reviewed Publications

Spatial and temporal dynamics of rapidly growing populations of tsetse flies at Nguruman, southwest Kenya during 1993-1995, were investigated, following six years of intensive population suppression with traps over a c. 100 km2 area. The two tsetse species present were randomly distributed in the short rainy season, but were aggregated in the dry and long rainy seasons. Maximum temperature was the dominant weather factor associated with the degree of aggregation. Trends in catches at 20 fixed sites along an 18 km north-south axis were weakly correlated between locations, possibly representing population sub-structuring. In particular, trends in population change were poorly …
