The current paper explores designing a web information retrieval system regarding the searching behavior of users in real and everyday life. Designing an information system that is closely linked to human behavior is equally important for providers and the end users.  From an Information Science point of view, four approaches in designing information retrieval systems were identified as system-...

High concentrations of ammonium in drinking water can cause many diseases and environmental problems such as eutrophication. Therefore, high-performance and eco-friendly methods for purification are of great importance and must be considered. Recently, bioelectrochemical systems have been successfully applied for the removal of many pollutants from water and wastewater. In the present work, amm...

This paper proposes an extended data envelopment analysis (DEA) model for deriving eco-efficiency. In order to derive eco-efficiency, the proposed model utilizes the concepts of operational efficiency and environmental efficiency. Since DEA can separately measure operational efficiency and environmental efficiency, the treatment for constructing the unified indicator is required to ultimately e...

Despite years of research and other activities in society the anthropogenic impact on nature still increase. Eco-design has a potential to reduce this impact, but yet a minority of companies practice it. The aim of this paper is to identify current challenges and trends within eco-design. In addition, the paper further aims to disclose important eco-design related research gaps. Eco-design chal...

With the increasing demand for wearable electronics (such as smartwatch equipment, health monitoring systems, and human–robot interface units), flexible energy storage systems with eco-friendly, low-cost, multifunctional characteristics, high electrochemical performances are imperative to be constructed. Nanocellulose sustainable natural abundance, superb properties, unique structures has emerg...

An intriguing alternative to traditional methods for regulating externalities is the provision of information about firms’ environmental attributes. An increasingly important example of this approach is “eco-labeling,” where a third party certifies firms’ products. Such schemes are currently are currently used in a variety of countries. This paper investigates the equilibria that may occur with...

life cycle assessment (lca) is one of the decision support systems which can be considered for assessing the different approaches of waste management. however, it only considers environmental effects and ignores other decision making options such as economic and social effects of solid waste management. in this research, we consider a combination of three decision making options including en...

A questionnaire study was conducted in order to identify relevant driver motives and assistance options for environmentally-friendly driving. Eighteen participants rated items belonging to the three factors time, environment, and consumption, and subsequently evaluated three types of driver assistance systems. Results concerning the motives showed that older drivers (above the age of 65) focuse...

PVM and other distributed computing systems have enabled the use of networks of workstations for parallel computation, but their approach of treating all networks as collections of point-to-point connections does not promote e cient communication|particularly collective communication. The E cient Collective Operations package (ECO) contains programs which solve this problem by analyzing the net...

We compared growth, leaf gas exchange characteristics, water relations, chlorophyll fluorescence, and Na(+) and Cl(-) concentration of two cultivars ('Koroneiki' and 'Picual') of olive (Olea europaea L.) trees in response to high salinity (NaCl 100mM) and elevated CO(2) (eCO(2)) concentration (700microLL(-1)). The cultivar 'Koroneiki' is considered to be more salt sensitive than the relatively ...
