Two medicinal plant of Sundarbans mangrove forest has been tested for the evaluation of growth inhibitory and antibacterial activity. The methanol extract of Xylocarpus granatum stem bark showed potent wheat rootlet (IC50 = 0.01 µg/ml) and shoot (IC50 = 0.23 µg/ml) growth inhibitory activity in a concentration related manner. The growth inhibitory activity was markedly decreased in residual methanol extract. The methanol extract showed antibacterial activity (MIC > 3 mg/ml) against Bacillus subtilis, Staphylococcus aureous and Proteus vulgaris. The residual methanol extract did not show any antibacterial activity. The results suggest the bioactive principle(s) of Xylocarpus granatum may be relatively non polar compound(s). The methanol extract and residual methanol extract of Sarcolobus globosus stem showed poor wheat rootlet and shoot growth inhibitory activity and no antibacterial activity.

Emerging Challenges and Roles for Quantity Surveyors in the Construction Industry
Shadi Shayan,Ki Pyung Kim,Tony Ma,Rob Freda,Zhuoran Liu KINFORMS 2019 Management Review Vol.14 No.1
The current ever-changing environment of the construction industry demands Quantity Surveyors to update their knowledge and skills to cope with the changes. In order to provide insights for Quantity Surveyors to be able to manage a construction project productively and increase their ability in accordance with the current demand of the construction industry, this research conduct a questionnaire survey and interviews. As a result, the most critical challenges for Quantity Surveyors are a) Adopting new technologies such as BIM for their current practice, and b) Increasing their knowledge regarding sustainable attributes for a construction project. This research also disclosed that the expected emerging roles for Quantity Surveyors are a) Sustainable Advisory ability, and b) BIM ability for cost management. The research findings are expected to advise the current Quantity Surveyor and Quantity Surveying companies to prepare future competencies in accordance with the global trend.
