Malaysia is not entirely spared from regular water shortages although it is located in a water rich region. The authors' previous study clarified that rainwater harvesting (RWH) might be one of the possible priority measure for promotion of water conservation. In line with such recognition, it is necessary to understand the relevant stakeholder's perceptions and attitudes towards the RWH practice. Thus, a set of structured interviews and questionnaire surveys were conducted among the stakeholders. Selangor, the most developed state in Malaysia was chosen as a case study. Herein, the stakeholders consist of (i) the fostering-side, namely the policy-makers, equipment-makers and NGOs/community leaders, and (ii) the accepting-side, namely the users and expected users of RWH. It is verified that the fostering-sides are generally in the medium level of participation. They are willing to support RWH on condition that accepting-sides become more positive to cooperate for RWH adoption. The accepting-sides are commonly in the low level of awareness. They seem to show more positive response when presented with proposal of low-cost RWH. To overcome the deadlock relationship between the two parties, several approaches that can be beneficial to both parties are proposed such as income tax and import duty exemption for rainwater harvesting system installations and reward-based RWH applications.

This study was conducted to determine the Ribavirin in Environmental and Biological Samples via Optical Chemical Sensor. In this paper, a new magnetic metal-organic framework Fe O @Fe-ASB was synthesized 3 4 with nano-Fe O as metal center and a new Schiff base, which was synthesized from quinoline-2-3 4 formaldehyde and β-mercaptoethylamine, as ligand, This Fe O @Fe-ASB was characterized by FITR, SEM 3 4 and XRD. Its enzyme-like activity was characterized by the chromogenic substrate (H O and TMB) and 2 2 verified based on the Michaelis-Menten equation. The results showed that the synthesis of Fe O @Fe-ASB was successful and it exhibited excellent 3 4 enzyme-like activity. The Fe O @Fe-ASB was successfully used for the detection of ribavirin in water 3 4 samples as catalytic material. It showed good stability, accuracy and precision. This testing method features a graph, which plots concentration (c) on the x-axis and absorption A on the y-axis to create a linear ribavirin-4-1-6-1 equation. It shows a good linear relation ranging from 1×10 mol l to 1×10 mol l , with a limit detection of-7-1 2×10 mol l. The mean recovery rates for spike recovery experiments varied from 92.0 % to 109 %. A new Schiff base was synthesized from quinoline-2-formaldehyde and βmercaptoethylamine. Then, a new magnetic metal-organic framework Fe O @Fe-ASB was synthesized by 3 4 it with nano-Fe O as the metal center. The Fe O @Fe-ASB was successfully used for the detection of 3 4 3 4 ribavirin in water samples as catalytic material. It showed good stability, accuracy and precision.

“…To 70 s, in order to meet the development of large irrigation areas in China, the aqueduct has changed greatly from design to construction, the water capacity of the aqueduct by several cubic meters per second to dozens of cubic meters, single span can be more than 100 meters, structure and construction develop greatly from the original assembly type to a variety of construction methods. The double crater double curved arch aqueduct built in Gaoyao County of Guangdong Province in 1975 has a span of up to 110 m (Ji 2012, Basheer et al 2017). Guangxi Yulin Wanlong hyperbolic arch aqueduct built in 1976 span up to 126 m. The development of the prestressed technology and the successful application of the bridge have further promoted the development of the construction of the aqueduct.…”

As the water resources distribution in China is extremely uneven, inter-basin water transfer project has become an important part of China's water conservancy construction. As part of the the major hydraulic structure in water delivery network across rivers and transportation routes, the design and analysis on aqueduct is important. En Zi Tan Aqueduct is located in Shimen County of Hunan in China. Main content of this paper is about the finite element analysis of the aqueduct on operation period. En Zi Tan Aqueduct is designed flow is of 5.0m 3 /s, longitudinal slope of 1/650, a total length of 1001m. The aqueduct is simple supported beam type, main body is reinforced concrete structure, the cross section is U-shaped and groove in each section length 13m. Top of the tank unilateral laying the bridge deck and railings in order to facilitate pedestrians. The study is using general finite element software to analize, stress and deformation changes on aqueduct body in the operation process; the water load and the earthquake influence on stress and deformation of aqueduct.
