Environmental meso-economics in university curriculum: new master program in environmental technology and management

A new Master Program in environmental technology and management has been developed in the framework of the Swiss-Jordanian cooperation, to ensure sustainable knowledge transfer in environmental management, technology, and economics. The areas represented in this program are cleaner production, hazardous substances management, and meso-economic analysis. All of these areas are under the theme of integrated resources management. The program implementation is carried out at Princess Sumaya University for Technology PSUT through cooperation with universities and environmental organizations in Switzerland, which was started in February 2008. The need for establishing this program in Jordan emerged from the practical experience of the Swiss partners who are working in environmental management. It was found that the concept of integrated resources management and the efficient utilization of resources were under estimated by practitioners. This leads to the urge of establishing a comprehensive program to upgrade the capacity of practitioners and new graduates to be able to handle environmental resources in a sustainable manner. For this purpose, the program includes and promotes the use of a number of tools. Meso-economic analysis is introduced in the program as a suitable tool to reflect the environmental values in monetary perspective, and to fill the gap at a meso (sector level) between the traditional micro (enterprise level) and macro (country level). Thus, meso-analysis comes out with integrated picture about the whole country’s sector and its related environmental damage and remediation options.     

Investigating benefits from the implementation of Environmental Management Systems in a Greek university

Higher Education Institutions (HEIs) can contribute significantly to the achievement of environmental sustainability through teaching and research activities, and also through improvements in the environmental management of University estates. This article explores the results of implementing Environmental Management Systems (EMSs) in a HEI in Greece. Specifically, the results of two surveys, focusing on students’ perceptions in the University of the Aegean, are presented and analysed. The surveys were conducted prior and after the implementation of an EMS in the University. The survey results demonstrate several positive consequences from the implementation of EMS across the University campus. In particular, there is a positive influence on students’ environmental awareness and behaviour, accompanied by greater preference among them for more participatory environmental management initiatives.     

Industrial ecology and the rediscovery of inter-firm recycling linkages: historical evidence and policy implications

‘Industrial ecology’ is one of the most influentialperspectives to have emerged in recent years in the wider discourseon ‘sustainable development’. The vast majorityof industrial ecologists believe that past economic developmentwas characterized by a linear system of extraction, use anddisposal. One of their main goals is therefore to find waysto make modern industrial economies mimic ecosystems by transformingthe waste of one firm into the valuable input of another. Historicalevidence presented in this article, however, demonstrates thatinter-firm recycling linkages were a dominant characteristicof past economic development. If this was the case, why do mostwriters on sustainability believe otherwise? I suggest two broadcategories of explanation: a lack of research into the spontaneousformation of inter-firm recycling linkages; and the progressiveand cumulative implementation of market distortions and regulatorybarriers to resource recovery over the last century. One implicationof these findings is that the most important task facing industrialecologists is probably not the technical challenge of planningresource recovery between firms, but the development of an institutionalframework that forces firms to ‘internalize their externalities’while leaving them the necessary freedom to develop new andprofitable uses for by-products.     

Microbe-Mediated Extracellular and Intracellular Mineralization: Environmental,Industrial, and Biotechnological Applications

Microbe-mediated mineralization is ubiquitous in nature, involving bacteria, fungi, viruses, and algae. These mineralization processes comprise calcification, silicification, and iron mineralization. The mechanisms for mineral formation include extracellular and intracellular biomineralization. The mineral precipitating capability of microbes is often harnessed for green synthesis of metal nanoparticles, which are relatively less toxic compared with those synthesized through physical or chemical methods. Microbe-mediated mineralization has important applications ranging from pollutant removal and nonreactive carriers, to other industrial and biomedical applications. Herein, the different types of microbe-mediated biomineralization that occur in nature, their mechanisms, as well as their applications are elucidated to create a backdrop for future research.

Anisotropy fields and FMR linewidth in single-crystal Al,Ga and Sc substituted hexagonal ferrites with M structure

Single crystals of nominally pure and of Al, Ga and Sc substituted BaFe₁₂O₁₉ ferrites have been grown from different solvents by the top seeding and bottom growth method. Ferrimagnetic resonance (FMR) measurements were made at room temperature on polished spheres of about 0.3 mm size at frequencies between 3 GHz and 90 GHz. From these measurements values of the anisotropy field from nearly zero up to 29 KOe were found for Sc-substitution levels x ≤ 1.65 and for Al levels x ≤ 2, respectively. The observed FMR linewidth ΔH can be described by a frequency independent two-magnon scattering contribution ranging between 5 Oe and 10 Oe, and an assumed intrinsic linewidth rising linearly with frequency and being for the substitutions studied proportional to the reciprocal of the Curie temperature. A relation predicting the dependence of ΔH on frequency and substitution level is proposed. The suppression of possible ferrous iron content by addition of Mn³⁺ reduces the linewidth by several Oersteds.     

Extraction of Sc from various media with triisoamyl phosphate: 2. Extraction of Sc from aqueous perchloric and hydrochloric acid solutions

The extraction of Sc from aqueous perchloric and hydrochloric acid solutions with triisoamyl phosphate (TIAP) was studied. The stoichiometry of the extractable complexes (ScA₃ · 3TIAP, A = ClO^4/? and Cl^?) was determined by the saturation and dilution technique. The isotherms of extraction of Sc from aqueous HClO₄ and HCl solutions were obtained. The extraction of impurity metals (Zn, Fe, Mo, Zr, Th, REE) was studied over wide HClO₄ and HCl concentration ranges.
