Aim There is increasing concern regarding sustainable management and restoration of planted forests, particuIarly in the Mediterranean Basin where pine species have been widely used. The aim of this study was to analyse the environmental and structural characteristics of Mediterranean planted pine forests in relation to natural pine forests. Specifically, we assessed recruitment and woody speci...

Background and Aim: The main goal of root canal treatment is to prevent or treat apical periodontitis. The aim of the present study was to assess the coronal restoration status, root canal filling quality, periapical health condition, and related factors in endodontically treated teeth at the Dental Faculty of Islamic Azad University of Medical Sciences, Tehran, Iran, in 2011-12. Materials and...

Policy to guide ecological restoration needs to aim toward minimizing the causes of ecosystem degradation; where causes cannot be eliminated or minimized, policy needs to shift toward accommodating irreversible landscape alterations brought about by climate change, nitrogen deposition, altered hydrology, degraded soil, and declining biodiversity. The degree to which lost diversity and ecosystem...

During the last years, electrical utilities began to install intelligent applications in order to assist Control Centre operators. The Verification and Validation (V&V) process intends to assure the reliability of these applications, even under incident conditions. This paper addresses the Validation and Verification of Knowledge-Based Systems (KBS) in general, focussing particularly on the V&V...

This paper introduces the problem of non-coal mine open pit waste dump in Shandong province, puts forward plant ecological restoration mode as solution, analyzes through adopting GIS and RS technology, from four aspects: elevation, slope, slope direction sensitivity design area, combines field investigation to carry out structural reinforcement on abandoned dump, design. The different species l...

Laser scanning methodology which has been used in different sectors, allow surveying an object by means of very dense and accurate point clouds acquisitions. The alignment and co-registration in a defined reference system allow generating a 3D model of the object, with the possibility to associate the radiometric information useful in many applications. In this paper, the operations in order to...

This book consists of 14 chapters covering important aspects in regards to various terrestrial ecosystems, wetlands, river systems, mine site rehabilitation, marsh ecology and heavy metals pollution. Also aims to fill some of the information gaps in ecological restoration, particularly in under-researched ecosystems around the world. Restoration ecology emerged as a separate field in ecology in...

1. In the face of continuing anthropogenic stressors to freshwater systems worldwide , the natural resilience and resistance of the freshwater ecosystems that enables them to cope with or recover rapidly from certain levels of perturbation is under significant threat. In many systems, the changes brought about through human activities have significantly altered the physical habitat and ecologic...
