Two water tupelo (Nyssa aquatica L.) stands in the Mobile Delta of Alabama were selected to test the hypothesis that mechanizedfelling does not reduce establishment and growth of natural water tupelo regeneration relative to traditional tree felling with chainsaws. To test the hypothesis, we established six, 2 ac treatment plots in each of two blocks on each of two sites, and randomly assigned ...

There is an increasing interest in the establishment of plantations in the Southeast region with the objective of producing biomass for energy and fuel. Establishment of these plantations will require the development of a feasible way to harvest them. These types of plantations are called Short Rotation Woody Crops (SRWC). Popular SRWC species are Eucalypt (Eucalyptus spp.), Cottonwood (Populus...

quercetin, a ubiquitous flavonol, represents a promising leading drug for development of new chemotherapeutic agents. however, its limited cytotoxicity to cancer cells hampers its clinical use. in order to obtain novel quercetin derivatives with superior cytotoxicity, seven alkylated quercetin derivatives were synthesized. solubility of these derivatives was determined by turbidimetry. cytotoxi...

| Damage detection using guided Lamb waves is an important tool in Structural health Monitoring. In this paper, we outline a method of obtaining Lamb wave modes in composite structures using two dimensional Spectral Finite Elements. Using this approach, Lamb wave dispersion curves are obtained for laminated composite structures with different fibre orientation. These propagating Lamb wave modes...

East African Blackwood is the common name for Dalbergia melanoxylon, the most valuable timber growing in the Miombo woodlands of southern Tanzania, and a potential flagship species to justify conservation of this habitat. The population density, structure and exploitation of this economically and socially important species were studied in an area of southern Tanzania. Harvestable timber was fou...

The concepts of sustainable original harvest (SOH) and sustainable disturbance harvest (SDH), and simple indices such as the ratio of successive harvests do not provide a reliable indication of the sustainability of a harvest. Some limitations of these concepts are illustrated in the context of selection harvesting of timber from natural forests. Four models are used to demonstrate that maintai...

The ongoing loss of red-listed coastal heathlands is a threat to biodiversity and cultural heritage legacies throughout the Atlantic regions Europe. It possible restore degraded afforested heathlands, but restoration interventions are often labour-intensive costly, outcome specific actions not well documented. We assess efficiency restoring through natural succession (i.e. ‘passive restoration'...

Abstract One of timber harvesting purposes is moving wood from the forest to sawmills. Road network planning requires consideration for alternatives. This paper purposed determine decision-making in selection alternative road networks with utility analysis by considering economic, ecological, and social criteria. The indicator used were length road, open area, cost construction, felling, skiddi...

Palm wine is the fermented sap of various palm trees especially Palmyra, silverdatepalm and coconut palms Palm wine can be obtained from the young inflorescence either male (or) female ones palm wine is alcoholic beverage that are made by fermenting the sugary sap from various palm plants. It is collected by tapping the top of the trunk by felling the palm tree and boring a hole into the trunk ...

Tracking&Tracing-systems have been used for years in the logistics and food industry for the monitoring, control and management of processes. In general, the usage of systems includes applications such as finding the source of recalls, proof of product quality and origin, improving logistics and production processes. The benefits of these systems in the specific environment of the wood supply c...
