An ethnobotanical survey of four villages in Bokkos district, situated in Bokkos Local Government Area of Plateau State was conducted between October and November 2019. Oral interviews were conducted among traditional medical practitioners, housewives, farmers, elderly men and women. From the survey, 50 plant species distributed across 22 families were recorded with at least one medicinal, food, fodder, spiritual significance and other economic value to man and livestock. Most of the plant families recorded belonged to the family Fabaceae, which accounted for 8 species (40%) of the total plant species recorded. This was clearly followed by the family Asteraceae which had 6 species (12%), and Euphorbaceae with 4 species (8%). The families Malvaceae, Lamiaceae, Moraceae and Verbenaceae had 3 species (6%) each. Apocynaceae and Poaceae had 2 species (4%) while Rhamnaceae, Vitaceae, Annonaceae, Rubiaceae, Araliaceae, Oxalidaceae, Asparagaceae, Commelinaceae, Araceae, Asphodelaceae, Pedaleaceae, and Loranthaceae had one species each. Fifteen (15) (30%) of the fifty (50) plant species were found to be used as food, condiments and spice. Seven (7) (14%) of the plants are used as fodder and 6 (12%) of the plants are used for spiritual purposes.

High temperatures might cause heat stress in laying hens. Even in a closed housing, the temperature will be higher at the outlet than it will be near the inlet. There was a decrease in wind speed due to negative pressure at the ¼, ½ and ¾ distance of placement of laying hens [1]. The placement zone of laying hens in a closed house can affect the temperature, humidity in the cage which is thought to also affect the health of laying hens in the starter period which will be seen from the blood profile of the laying hens. The materials of this research were DOC of laying hens which were kept in a closed house. The method used was a direct experiment. The measurement of temperature and humidity in the closed house was carried out for 38 days during the research period. The hematological tests were carried out when the laying hens were.........

The integration of genetic algorithms to optimize the networks of value chains could enormously improve the performance of supply chains. For this reason, this paper describes in more detail the application of genetic algorithms in the value chains of the automotive industry. For this purpose, a theoretical model is built up to evaluate whether the application of the model can optimize the value chain. This option is described, analyzed and its restrictions are shown. Instead of looking at the entire network, individual finished goods and their bill of material are used as a basis for optimization, which greatly reduces the complexity of the original problem. The original complexity of the supply chain networks can thus be reduced and considered based on the bill of material.

Maritime relations prevail in our times and the influx of refugees, in order to arbitrate to resolve disputes arising from them. Where the parties to these relationships agree to entrust them with the status or future disputes arising from them to special arbitrators, their choice of those with proven competence and the experience they have with the competence and experience of the expert. If the maritime arbitration has arisen when the Romans, and spread to the Middle Ages, a simple and flexible as a system and a specialist to resolve maritime disputes, it has met popular and prosperous unparalleled in modern times because of the booming international trade, trade between different countries and exchange in the world as a whole east and west, north and south As this trade exchange has found its preferred method of maritime transport, despite the increasing importance of road and air transport in this era, the transportation method is transportable. And for the large volumes of cargo transported by it Compared

The ability to recognize abnormal behaviour is important for health monitoring systems in smart home. Taiwan will have at least 20 percent of the population over 65 by 2025. Smart home is one of solution used to assist elderly live independently. We designed a SVM-based learning model to classify activities of daily living and to analyze an individual's daily routines and habits, typically for the elderly who live alone. The temporal information and spatial sequences collected over time are used to generate pattern, which can be fitted to the training data and the fitted model can be used to make a prediction. One of the CASAS smart home datasets was used to train and to retest the algorithm. A non-trained dataset was also used to validate the accuracy of the algorithm. Abnormal behaviors can be detected by compared with individual's daily activity pattern as baseline. Through detecting and distinguishing the abnormal behaviors of elder's daily activities, it can provide assistances on elder's independent living and improvement of aged quality of life.

This paper deals with the development of a software for progressive collapse analysis of ship hull girder structures. The progressive collapse phenomenon of the ship structures is a design problem that requires proper analysis to ensure structural integrity, reliability and safety of the ship throughout her lifecycle. The ship structure may deteriorate in service due to several factors. An aging ship is often exposed to corrosion as its operational environment even increases the structural corrosion. Fatigue crack and corrosion-enhanced fatigue becomes eminent as the ship continues in operation. These factors have called for concern in the design cycle to develop tools that could assess the health of the ship structures at the preliminary stage of the design. To address, this issue, several methodologies were used in the development and implementation of the software application. The program was designed in a general-purpose programming language that is platform independent. In this case, Java......
