Most manufacturers do not develop or support token ring technology, so in addition to the increased cost of purchasing equipment, there is the added difficulty of finding the Root pruning, an ancient Asian practice, and other controlled damaging, such as driving nails into the trunk or beating the branches and trunk, produce results that are similar to girdling. The repeaters can boost the data and data can travels in the long distance also. Ring topology is slower in performance than Ethernet network. This makes it slower than Star topology. the performance of the entire network. There is no need for an administrator computer to control the network. Consider the development of alternative resources for future rural medical care currently based on tree bark: bark from old trees, on a small scale and as part of a sustainable forest management system; from planted trees in forest rehabilitation plantings adjacent to the forest or within suitable sites within the village; and harvesting leaves and young bark from short-rotation coppice stands in suitable sites outside the forest.

The studies were not concerned with what the bark is used for, but focused on understanding the basis for better and sustainable harvesting practices and developing rural institutions through which bark harvesting could be managed in a participatory approach. In general, it would be better to cut a few selected trees, harvest all the bark up to the smaller branches, and possibly also use the wood, and then manage tree recovery through coppice management (using some cut branches to protect the coppicing shoots against browsing from livestock and antelope), or seedling regeneration. Liji practiced as a full-time consultant in obstetrics/gynecology in a private hospital for a few years following her graduation.
