We briefly present a synthesis of theoretical models in eco-epidemiology which merges the fields of ecology and epidemics. In particular we discuss the role of parasites/pathogens in community assembly formation and species coexistence, as well as the potential of biological control. Recent works have revealed that the complexity in parasite-mediated interactions can alter the dynamic behavior ...
scientists call pasture a natural eco-system and range is an agricultural eco-system. in this point of view although pasture that was full of plants growing by itself and not growing by human being (pirdashti, 2007; mohgadam, 2005) and two groups of living beings such as human being, plants, domesticated, and not living being like weather, wind, gradient which are effective in making of pasture...
Eco-efficiency is a tool for sustainability analysis that indicates how to carry out economic activities effectively. This paper assesses agricultural eco-efficiency using data envelopment analysis (DEA) and the Theil index approach. Using basic data of 31 provinces in China during 2003–2013, we analyzed the agricultural eco-efficiency development level and spatial pattern in China. The results...
We have now enough background in the teaching of eco-design to make some conclusions on practices and evolutions in this area; in France these teachings are very supported by studies of APEDEC (Association of Experts for the Development of Eco-Design) that published in 2006 and 2010 the results of enquiries concerning this subject. Curricula concerning eco-design exist since 1987 but a signific...
Metastatic breast cancer is the second leading cause of cancer-related deaths among women. Triple-negative breast cancer (TNBC) is a highly aggressive subcategory of breast cancer and currently lacks well-defined molecular targets for effective targeted therapies. Disease relapse, metastasis, and drug resistance render standard chemotherapy ineffective in the treatment of TNBC. Because previous...
BACKGROUND High levels of exhaled carbon monoxide (eCO) are a marker of airway or lung inflammation. We investigated whether hypo- or hyperventilation can affect measured values. METHODS Ten healthy volunteers were trained to achieve sustained end-tidal CO2 (etCO(2)) concentrations of 30 (hyperventilation), 40 (normoventilation), and 50 mmHg (hypoventilation). As soon as target etCO(2) values...
Eco-driving is a driving style that can significantly reduce fuel consumption and CO2 emission. Current methods for eco-driving practice are inefficient or not easily accessible. Therefore, we introduce iCO2, an online multi-user three-dimensional (3D) ecodriving training space, which was developed in Unity3D and made available as a Facebook application since September 2012. In iCO2, agents are...
A friendly benign, green, rapid and facile strategy for synthesis a series of arylquinoxalines was achieved by condensation of aromatic 1,2-diamines with arylglyoxals under clay-catalyzed as an inexpensive and eco-friendly catalyst using grindstone chemistry. Significant decreases in reaction times and high yields have been observed by this green chemistry approach in comparison with previously...
Number: 007-0582 Abstract Title: A Closed-loop Supply Chain Model for Managing Overall Optimization of Eco-efficiencyTitle: A Closed-loop Supply Chain Model for Managing Overall Optimization of Eco-efficiency Authors: Name: Wei D. Solvang, Ziqiong Deng, Bjoern Solvang Organization: Department of Industrial Engineering, Narvik University College, Norway Address: Lodve Langes gate 2, pb. 385, N-8...
Ecological security is an important basis of the entire human security system, the cornerstone for human survival. Knowing the status of ecological security is crucial for making decisions to avoid ecological disaster. Existing research, both the basic research on ecological security mechanism and information service systems, is still primitive in their abilities to resolve eco-security problem...
