Metal-functionalized covalent organic frameworks as precursors of supercapacitive porous N-doped graphene
2017
Covalent Organic Frameworks (COFs) based on polyimine with several metal ions (FeIII, CoII and NiII) adsorbed into their cavities have shown the ability to generate N-doped porous graphene from their pyrolysis under controlled conditions. These highly corrugated and porous graphene sheets exhibit high values of specific capacitance, which make them useful as electrode materials for supercapacitors.
The modes of supply net management: a capability view
2007
Purpose – The purpose of this paper is to identify the key capabilities required in supply net management.Design/methodology/approach – Uses the Management Capability Framework to break down supply net management into different modes and identify capabilities required in them.Findings – Reveals that the supply activity of companies increasingly takes place in intentionally developed strategic networks called supply nets. These networks pose distinctive challenges for supply chain management. Identifies four diverse but simultaneously extant modes of management in the supply net context, and discusses the key managerial capabilities in each mode.Originality/value – Provides a conceptual fram…
Real-time flaw detection on complex part: Study of SVM and hyperrectangle based method
2002
We present in this paper the study of two classifications methods used in order to control in real-time some industrials parts. We present the practical frame in which is made the operations, natures of the anomaly to be detected as well as the features extractions method. We tested two techniques of classification, with different algorithm complexities and performances. We compare the results obtained on various features spaces. We end by a combinatorial perspective of results of classification.
Equity in REDD+: Varying logics in Tanzania
2015
Equity is frequently cited as one of the key design aspects of environmental governance regimes. In the context of Reduced Emissions from Deforestation and Forest Degradation (REDD+), a forest-based climate change mitigation instrument, the manner in which ‘equity’ is understood will be of critical importance for the impacts and acceptance of REDD + policies and initiatives. Whereas the concept has been extensively studied in the academic literature, references to equity in REDD + policy debates and documents are often vague, leaving room for various interpretations and modes of implementation. In our case study of the Tanzanian national REDD + policy domain, we provide a conceptual framewo…
Information and communication technologies in rural hotels
2010
There is a consensus about the beneficial effects of the applications of information and communication technologies (ICT) in several business contexts. Rural tourism companies have embraced these technological advances that have made a positive contribution to their quick expansion in recent years. Nevertheless, some technologies have received scarce attention from rural accommodation managers. The aim of this paper is to generate a conceptual framework on ICT development in the tourism market and, in particular, in rural accommodations. Thus, we aim at providing an overview of the main technological developments applied in this sector, analysing the level of ICT implementation in Spanish r…
Smart Sustainable Development Approach and its Implementation in Engineering Organizations
2014
This paper explores the concept of sustainability in engineering systems and proposes a smart conceptual framework for engineering organization development. Sustainability is a critically complex goal for enterprise activity and development. Sustainability in the engineering area requires a comprehensive and continue approach because, a) engineering activities are ubiquitous in society, b) of the high importance of engineering applications in the development of the companies and of the world, and c) technological support becomes imminent in a dynamic economic environment and sustained in large part by technological advances. This paper aims to provide to the engineering environment a smart …
Clashing Perspectives on Sustainable Development
2019
Abstract We live in a world characterised by speed owing mainly to technology. Everything happens at a faster pace, from the way production and consumption takes place to the way the environment is degrading. Henceforth, sustainable development appeared in response to these consequences. However, considering that we are discussing the topic of sustainable development for over three decades now, it is probably time to bring it forward in another way and try to better understand it through opposing perspectives. Therefore, the present paper explores differing views on the discussed topic, and analyses sustainable development in relation to other similar terms, trying to provide a clear meanin…
Metal–organic framework technologies for water remediation: towards a sustainable ecosystem
2018
Having access to clean water is a mandatory requirement for the proper development of living beings. So, addressing the removal of contaminants from aquatic systems should be a priority research topic in order to restore ecosystem balance and secure a more sustainable future. The fascinating structures and striking physical properties of metal–organic frameworks (MOFs) have revealed them as excellent platforms for the removal of harmful species from water. In this review, we have focused our attention on critically highlighting the latest developments achieved in the adsorptive removal of inorganic – metal cations, inorganic acids, oxyanions/cations, nuclear wastes and other inorganic anion…
Complexity Theory for a New Managerial Paradigm: A Research Framework
2015
In this work, we supply a theoretical framework of how organizations can embed complexity management and sustainable development into their policies and actions. The proposed framework may lead to a new management paradigm, attempting to link the main concepts of complexity theory, change management, knowledge management, sustainable development, and cybernetics. We highlight how the processes of organizational change have occurred as a result of the move to adapt to the changes in the various global and international business environments and how this transformation has led to the shift toward the present innovation economy. We also point how organizational change needs to deal with sustai…
Closing in on the toxic domain through analysis of a variant Clostridium difficile cytotoxin B
1995
Strain 1470 is the standard typing strain for serogroup F of Clostridium difficile containing both toxin genes, toxA-1470 and toxB-1470. A polymerase chain reaction (PCR)-based approach to the sequencing of the total toxB-1470 gene identified an open reading frame (ORF) of 7104 nucleotides. In comparison with the previously sequenced toxB of C. difficile VP10463, the toxB-1470 gene has 16 additional nucleotides, 13 within the 5'-untranslated region and three within the coding region. The M(r) of ToxB-1470 is 269,262, with an isoelectric point (IP) of 4.16. The equivalent values for ToxB are M(r) 269,709 and IP 4.13. In comparison with ToxB, ToxB-1470 differs primarily in the N-terminal regi…
