A method is offered to estimate downtime (the time to restore a facility to operability, not total repair time) for second-generation performance-based earthquake engineering. It applies in cases where downtime is primarily controlled by nonstructural systems (although red-tagging and lifeline failure are addressed); restoration begins immediately after the earthquake; and components are repair...
Opportunities for dual restoration and carbon benefits from naturally regenerating woody ecosystems in agricultural landscapes have been highlighted recently. The restoration capacity of woody ecosystems depends on the magnitude and duration of ecosystem modification, i.e., the "agricultural legacy." However, this legacy may not influence carbon sequestration in the same way as restoration beca...
Ecological restoration enjoys widespread use as a technique to mitigate for environmental damage. Success of a restoration project often is evaluated on the basis of plant cover only. Recovery of a native arthropod fauna is also important to achieve conservation goals. I sampled arthropod communities by pitfall trapping in undisturbed, disturbed, and restored coastal sage scrub habitats in sout...
Restoration efforts in Florida's Everglades focus on preserving and restoring this unique wetland's natural landscape. Because most of the Everglades is a freshwater peatland, it requires surplus rainfall to remain a peatland. Restoration plans generally assume a stable climate, yet projections of altered climate over a 50-year time horizon suggest that this assumption may be inappropriate. Usi...
The amount of ecological restoration required to mitigate or compensate for environmental injury or habitat loss is often based on the goal of achieving ecological equivalence. However, few tools are available for estimating the extent of restoration required to achieve habitat services equivalent to those that were lost. This paper describes habitat equivalency analysis (HEA), a habitat-based ...
The “biological restoration” is an excellent technique for reconstruction in young traumatized teeth, which is used as intra-root reinforcement an extracted natural tooth. This article reports a case where an 11-year-old patient had his upper incisors affected by fractures from trauma. Due to the young age of the patient, the absence of the natural tooth fragment, the major structural loss and ...
peripheral nerve injuries (pni) can lead to lifetime loss of function and disfigurement. different methods such as conventional allograft procedures and using of biological tubes have problems for damaged peripheral nerves reconstruction. designed scaffolds with natural and synthetic materials are now widely used in the reconstruction of damaged tissues. utilization of absorbable and non-absorb...
Glass ionomer based materials are clinically popular in several areas of restorative dentistry, but restoration of cervical lesions has proven particularly successful. Various etiologies, conformations, locations and structural characteristics make non-carious cervical lesions more challenging to adhesive restorative procedures and marginal seal in the long run. Due to their characteristics, gl...
Death Rides the Forest: Perceptions of Fire, Land Use, and Ecological Restoration of Western Forests
Large wild fires occurring in forests, grasslands, and chaparral in the last few years have aroused much public concern. Many have described these events as “catastrophes” that must be prevented through aggressive increases in forest thinning. Yet the real catastrophes are not the fires themselves but those land uses, in concert with fire-suppression policies that have resulted in dramatic alte...
Pathology is a crucial basis in the process of restoration of historical monuments. So as just by an accurate pathology, a correct and effective restoration plan will be achieved. Amongst the various and different types of damages occurring in the historic monuments, Structural cracks in the walls are very important and considered as special issues that can endanger the stability and structural...
