a r t i c l e i n f o The ecological, economic and socio-cultural roles of forests are under threat in Ghana due to the high rate of deforestation. Efforts are being made to combat this problem through rehabilitation measures. However, the costs of deforestation and restoration benefits are not adequately estimated. This paper fills in the gap in knowledge by providing an empirical estimation o...

A matrix growth model is estimated on the basis of growth data (growth period 5 years) of 14 measurement plots of uneven-aged white pine from southern Ontario. The impact of three economic factors specific to the private forests on the sustainable management of private woodlots is evaluated and discussed, and the trade-off between environmental and economic values is examined. These three econo...

Exotic tree plantations have been considered as a management strategy for the rehabilitation of indigenous tree communities in situations that require human intervention to assure forest ecosystem rehabilitation. This study evaluated the value of pine Pinus caribaea and Pinus patula and cypress Cupressus lusitanica plantations as a means o f permitting indigenous trees to become established on ...

This group was formed to provide the opportunity for persons skilled in applied science and technology to contribute to the welfare of the physically handicapped. The purpose of the group was: "to assist the medical profession in the diagnosis...

Nacrtak Assessment of disturbance can provide forest managers with information to make appropriate decisions on site rehabilitation and monitoring. This paper evaluates the accuracy of successive estimates of site disturbance using two ground survey methods. The results from the point transect and grid point transect and grid point intercept methods were compared with the results from an intens...

Virtual rehabilitation environments may afford greater patient personalization if they could harness the patient’s affective state. Four states: anxiety, pain, engagement and tiredness (either physical or psychological), were hypothesized to be inferable from observable metrics of hand location and gripping strength -relevant for rehabilitation-. Contributions are; (a) multiresolution classifie...

Himalaya is a vast and diverse mountain system. Agro forestry land use covering (20%) of geographical area of Indian Himalayas is distributed as patches in the matrix of forest covering (52%) area. Forest based treecrop livestock integrated farming is the predominant traditional land use in central Himalayas.1 Hill agriculture appears to be key threat to soil biodiversity and ecosystem service ...
