Efficiency is a major concern for real-time systems. Realtime software is often written in assembly or other low level languages like C. Programmers hesitate to use newer objectoriented techniques since these are perceived as less efficient. This work explores the OO design techniques for embedded operating system, taking into account real-time goals so that the design is efficient and meets sy...

Purpose Recent OECD (2010, 2011) reports argue that eco-innovation is the key to realising growth. The purpose of this paper is to analyse the drivers of eco-innovation and to compare the impact of eco-innovation and non-eco-innovation on firm performance. The paper provides insights into the role government regulation can play in directing and stimulating eco-innovation. Design/methodology/app...

Exhaled carbon monoxide (eCO) and fractional exhaled nitric oxide (FeNO) could reflect underlying inflammatory and oxidative stresses, which play important roles in pathogenetic pathways of metabolic syndrome (MetS). However, epidemiologic evidence was limited. We conducted a study in Wuhan-Zhuhai (WHZH) cohort of 3649 community participants to investigate the association between eCO, FeNO and ...

Biogeosciences Discussions This discussion paper is/has been under review for the journal Biogeosciences (BG). Please refer to the corresponding final paper in BG if available. Abstract An automated open system for measurement of soil CO 2 efflux (R sc) was developed and calibrated against known fluxes and tested in the field, while measuring soil respiration also by the gradient method (R sg) ...

The distribution of goods in urban areas, together with private traffic flows, are among the main sources of energy consumption, air pollution and noise. As a consequence, in the 2000s, several EU cities started to implement logistical solutions for the sustainable city. In this context, this study addresses the implementation of a new eco-logistic system, which serves multiple adjacent cities ...

Previous studies discuss how regulatory, technological and market drivers increasingly challenge manufacturing industries to adopt eco-innovations. However, the understanding of the process by which eco-innovations are developed and commercialized as a result of these drivers is not yet well established, in particular because these drivers are perceived differently by the end-users and their su...

nano sio2/hyperbranched polyglycerol (hpg)/so3h catalyst was readily prepared for first time from inexpensive starting materials in aqueous media which catalyzed the synthesis of benzoic acid. ftir spectra, x-ray diffraction (xrd) and transmission electron micrographs (tem) was employed to characterize the properties of the synthesized nano sio2/hpg/so3h. high catalytic activity and ease of rec...

The article aims to investigate the presence of a correlation between eco-innovation and economic performance within industrial districts. The case analyzed in this article is based on a study concerning a sample of 54 Italian industrial clusters entitled "Eco-Districts" that has compiled a list of the most eco-efficient districts at the national level. After selecting two districts, this study...

This study presents external costs and eco-efficiency parameters associated to exhaust emissions in Las Palmas Port. Emission assessment is based on a vessel emissions inventory obtained from the full bottom-up Ship Traffic Emission Assessment Model and messages transmitted by the Automatic Identification System over 2011. External costs are estimated based on a top-down approach. Results are c...

We study an eco-epidemic model with two trophic levels in which the dynamics are determined by predator-prey interactions as well as the vulnerability of the predator to a disease. Using the concept of generalized models we show that for certain classes of eco-epidemic models quasiperiodic and chaotic dynamics are generic and likely to occur. This result is based on the existence of bifurcation...
