Monitoring of sanitary landfill with volatile organic halocarbons as indicators - a case history.
Comparison of co-digestion performance of two differently collected organic fractions of municipal solid waste with sewage sludges
This paper deals with the comparison of the co-digestion performances of two digesters treating organic fractions of municipal solid wastes (MSW) and primary and secondary sewage sludges mixed at various ratios between 0 to 100% TS basis. The organic fractions treated differ in their collection procedures, which influence the chemical characteristics of the substrates and then the process performance. These differences and their influence on the anaerobic digestion process are emphasized throughout the paper so as to assist public sector managers in their choice of treatment method from the harvesting procedure to the final disposal technology of MSW
Advanced strategies for the management of biodegradable organic wastes from agro-industry: Technological aspects, energy recovery and agricultural reclamation perspectives
Si tratta di una relazione invitata nell'ambito di un evento bilaterale Italia-URSS teso ad illustrare le più recenti acquisizioni scientifico-tecnologiche in ambito italiano quale base per possibili collaborazioni con la ricerca e lo sviluppo applicativo dei processi ambientali nel contesto sovietico
Comparison between the use of volatile organic halocarbons and routine parameters in the monitoring of sanitary landfill environmental impact.

Trattamento anossico su reattore a letto fluidizzato, di reflui industriali
Vengono riportati i risultati di una sperimentazione condotta in reattore anaerobico a letto fluido, con biomassa adesa, per l'abbattimento del carico inquinante di reflui industriali
Anaerobic treatment of chemical wastes
The effluents of chemical industries, which include several organic solvents and other toxic chemicals, are generally treated by aerobic process, which is cost intensive in nature. The alternative anaerobic route to degrade the toxic effluents is attractive due to the lower cost of treatment and the generation of gas, which can supplement the energy requirements. There are few reports on the anaerobic treatment of the chemical effluents. In the present investigation, the industrial effluents from industrial productions, which utilizes several organic chemicals, have been taken to assess their applicability for anaerobic treatment
Going Beyond Counting First Authors in Author Co-citation Analysis
The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
