This paper established a system dynamics model of energy saving and emission reduction in coal mining area, as well as conducted simulation of different development plans, based on the analysis of energy saving and emission reduction factor of coal production links, of the complex structure of energy saving and emission reduction system in coal mining area, and of the dynamic feed-back mechanis...

Abstract Reducing the climate change-induced risk of uncontrollable fires in landscapes under nature management, with severe impacts on landscape and society, is particularly urgent densely-populated fragmented areas. fire such areas requires active involvement a wide diversity stakeholders. This research letter investigates stakeholders’ needs regard to reduction Veluwe area Netherlands. dense...

A recently calibrated urban runoff model, the Source Loading and Management Model (SLAMM), is used to compare the cost-effectiveness of using source area and regional stormwater treatment practices. The demonstration is done for the totally urbanized Lake Wingra watershed in Madison, Wisconsin. The goal is to retrofit practices that are able to reduce the annual total suspended solids load by 4...

abstract the oak leafroller moth , tortrix viridana l. is a destructive pest within it’s spreading area which invades the oak species, especially in west and northwest forests of iran, in recent years. some parts of west azarbayjan’s forests which are located in piranshahr and sardasht region have been affected by this pest since 1989 that oak trees vigor and survival have been gone down result...

background early postoperative edema and ecchymosis are the most common factors to complicate initial patient perceptions about rhinoplasty. the current study was conducted to determine the effects of longer steri-strip tape on patient cheek in terms of ecchymosis control and reduction. methods through a randomized controlled clinical trial, 70 patients who underwent rhinoplasty were randomly e...

one of the indicators of management and sustainability control of forest resources is the definition deforestation and degradation types. these factors hazard quantitative and qualitative of the iranian forests. in this study with integrated approach, different forms of forest degradation identified in the forest areas with a reviews of library resources and then investigation the degree of sta...

in order to study the effect of light quality and quantity on morphological and physiological characteristics of two late and early maize (zea maize l.) s.c., an experiment was conducted in greenhouse conditions, ferdowsi university of mashhad, iran, during 2008. the experiment was carried out factorial based on randomized complete block design with six treatments and three replications. differ...

A carbon black transference technique was used to determine the contact area in twenty-three dissected tibiotalar articulations, with the talus in neutral position and displaced one, two, four, and six millimeters laterally. The greatest reduction in contact area occurred during the initial one millimeter of lateral displacement, the average reduction being 42 per cent. With further lateral dis...

In this paper, we propose a powerand area-efficient architecture of Turbo decoder. In order to improve the nonfunctional performance metrics such as power consumption and area, we use the trade-off method between bit error rate (BER) performance and the two non-functional performance metrics. Our proposed architecture shows about 16.7% reduction in power consumption and about 22.5% reduction in...
