    Electrochemical Sensors Based on Carbon Nanotubes

    ELECTROANALYSIS, Issue 23 2002
    Qiang Zhao
    Abstract Carbon nanotubes are attractive new materials. It has been about a decade since carbon nanotubes were discovered. Carbon nanotubes have many outstanding properties and have many practical or potential applications. In this short review we introduce recent advances in carbon nanotubes as potential material for electrochemical sensors. The advantages of carbon nanotubes as sensors are discussed along with future prospects. [source]

    Rainfall-induced landslides and debris flows

    HYDROLOGICAL PROCESSES, Issue 4 2008
    Giovanni B. Crosta
    Abstract In this preface we introduce the special issue on rainfall-induced landslides and debris flows. The topic is of high interest for many practical and scientific reasons. In fact, rainfall is the most relevant factor for the triggering of both shallow and deep-seated landslides, and rainfall analysis is the most frequently adopted approach for forecasting the occurrence of such phenomena. The six papers of the special issue cover most of the key issues relative to rainfall-induced landslides. Starting from the analysis of these contributions, we identify and discuss, in this paper, several main topics that deserve further research in the field of rainfall-induced landslide, such as the uncertainty of the data, the quality of geotechnical analysis, the validation of the models, and the applicability of results in the framework of natural hazards.

    Inducements for medical and health research: issues for the profession of nursing

    JOURNAL OF CLINICAL NURSING, Issue 7 2007
    FRCNA, Linda Shields PhD
    Aims and objectives., Inducements, incentives, reimbursements and payment to subjects for participation in research projects raise many practical, professional and philosophical issues for nurses. Nurses are enjoined, either formally as research co-participants or informally as patients' professional carers, in any research which involves their patients. This role inescapably brings significant ethical obligations, which include those of bioethical audit. Background., A review of current international guidelines on reimbursement recommendations indicates that researchers select one of several paradigms which range from the ,commercial market model' of supply and demand to that of pure un-reimbursed altruism. In this latter, volunteers not only give their bodies and emotional commitment, but also sacrifice their time and convenience. Inducement is defined as the provision of resources or rewards which exceed the ,resource neutral' compensation for legitimate expense. If potential volunteers are truly free to make an informed choice to participate in research, no ethical compromise exists if inducements are offered; but by so doing both the research team and the volunteer patients have shifted the ethos of their research from caritas and altruism to one of a simple commercial relationship. Conclusions., Inducements are inappropriate when offered to those who are ,ethically captive' in the sense that autonomy of choice may be compromised. Relevance to clinical practice., In contemporary nursing practice, research involvement is both frequent and desirable. A perspective of current debate about inducements for volunteering, including legal and ethical issues, empowers nurses to protect the patients or clients in their care. [source]

    Non-blocking decentralized control of discrete event systems based on Petri nets,

    ASIAN JOURNAL OF CONTROL, Issue 3 2010
    Feihua Lu
    Abstract The non-blocking property of discrete event systems can formulate many practical and important properties of manufacturing systems, such as deadlock freeness, liveness and reversibility. But it is difficult to guarantee non-blocking control. This paper presents a hybrid approach to decentralized control of discrete event systems. More generalized constraints are considered in this approach, which gives a graphical way of designing coordinators to keep the non-blocking property of the closed-loop system with decentralized supervisors. This approach also guarantees that the closed-loop system is maximally permissive. Copyright © 2010 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society [source]
