Roselle (Hibiscus sabdariffa L.) from Malvaceae family is an annual crop with potential for use by many industries including food, animal feed, neutraceutical, cosmeticeutical and pharmaceutical industries. Its origin is not fully known but it is believed to be from West Africa, although the plant is found native from India to Southeast Asia. The calyxes, stems and leaves are acid in flavour. The juice is produced from the calyces, and it is claimed to be a prohealth drink due to its high contents of ascorbic acid, anthocyanins and other antioxidants.
Recently, wireless sensor network (WSN) applications have seen an increase in interest. In search and rescue, battlefield reconnaissance, and some other such applications, so that a survey of the area of interest can be made collectively, a set of mobile nodes is deployed. Keeping the network nodes connected is vital for WSNs to be effective. The provision of connectivity can be made at the time of startup and can be maintained by carefully coordinating the nodes when they move. However, if a node suddenly fails, the network could be partitioned to cause communication problems. Recently, several methods that use the relocation of nodes for connectivity restoration have been proposed. However, these methods have the tendency to not consider the potential coverage loss in some locations. This paper addresses the concerns of both connectivity and coverage in an integrated way so that this gap can be filled. A novel algorithm for simultaneous-node repositioning is introduced. In this approach, each neighbour of the failed node, one by one, moves in for a certain amount of time to take the place of the failed node, after which it returns to its original location in the network. The effectiveness of this algorithm has been verified by the simulation results.
Isolated fallopian tube torsion is an uncommon diagnosis. It is particularly rare in the paediatric and post-menopausal age groups. It lacks pathognomonic symptoms, signs and imaging findings, yet each of these diagnostic steps plays a crucial role in early diagnosis. We describe two cases of isolated fallopian tube torsion in prepubertal females.
