Published: July 2020

Abstract
The access of the distributed generator supply provides a supportive effect for the node voltage in the active distribution network, but at the same time also reduces the stability of the distribution network. The algorithm establishes the sensitivity matrix and analyzes the relationship between the node voltage and the reactive power output, to coordinating the output of each reactive power. Since the undervoltage and overvoltage of different nodes can be present in the network at the same time, the overvoltage and undervoltage can be adjusted, which achieve the control of the network node voltage. The simulation results show that the algorithm can realize the effective return of the node voltage and increase the stability of the distribution network voltage.

Abstract
Because of the increasing demand of modern residents for electric energy, the power supply load of electric power enterprises also increases. Under this condition, affected by the randomness of electricity consumption behavior of different residents, the electricity load generated by each resident will fluctuate greatly, which directly leads to the decline of power safety level. Under this condition, as the power manager, the power enterprise must guarantee the operation safety of the system and scheduling is the main means to achieve the goal. However, if the dispatching work is not carried out in time, it cannot completely eliminate the impact of residential power load. At this time, modern scholars put forward a super short-term forecasting technology of residential power load based on long-term and short-term memory cyclic neural network. The implementation of this technology can provide strong support for the power dispatching work, make the dispatching work more real-time, thus avoiding the negative residential power consumption the impact of the lotus. This paper mainly studies the ultra-short term forecasting of residential power load, expounds the basic concept and model building method of this method, and verifies its effectiveness through simulation and examples.

Abstract
With the development of times and technology, the iprovement of technology has promoted the progress of blueberry juicing device at the same time. However, there are still defects. The current blueberry juicing device cannot improve the yield and anthocyanin content. Therefore, it is easy to waste raw materials. So a device to improve the juice yield and anthocyanin content in blueberry juice is designed to solve this problem. The device enables the squeezed residue discharged into the distillation drum through the slag discharge tube. At the same time, citric acid and sucrose solution is added into the distillation cylinder combined with solution storage tank. Hence it enables the heating of the heating silk base and make a small amount of juice in the residue extracted and evaporated under acidic conditions. Meanwhile, it is conducive to the dissolution of anthocyanins in the residue so that the evaporated steam is discharged into the cooling tube through the distillation tube for condensation and then into the collection tube for collection. The device can improve the juice yield and anthocyanin content of blueberry juice.

Published: July 2020

Abstract
The application of distributed power in the system has changed many characteristics of the traditional distribution network. Based on the consideration of the randomness of the load and the fluctuation and randomness of the output of the distributed generation, a new reconfiguration model of the distribution network with microgrid is established in this paper. Dynamic reconstruction is not a simple superposition of reconstructions in sub-periods. The influence of the number of switching operations on the operation mode between adjacent sub-periods and the overall optimality of the objective function must also be considered. The mathematical probability models of distributed generations and load are constructed in this paper. The dynamic reconfiguration is completed on the basis of probabilistic power flow. The objective function is calculated by stochastic power flow. The optimization algorithm is applied to the reconstruction process. The simulation results verify the effectiveness of the proposed model and algorithm in dynamic reconstruction.

Published: July 2020

Abstract
The blood-brain barrier (BBB) protects the human brain from external aggression. Despite its great importance, very few in vitro models of the BBB reproducing its complex organization are available
yet. Here we fabricated such a three-dimensional (3D) self-organized in vitro model of BBB microvasculature by means of a combination of collagen microfibers (CMF) and fibrin gel. The interconnected fibers supported human brain microvascular endothelial cell migration and the formation of a capillary-like network with a lumen diameter close to in vivo values. Fibrin, a protein involved in blood vessel repair, favored the further 3D conformation of the brain microvascular endothelial cells, astrocytes and pericytes, ensured gel cohesion and avoided shrinkage. The maturation of the BBB microvasculature network was stimulated by both the CMF and the fibrin in the hydrogel. The expression of essential tight-junction proteins, carriers and transporters was validated in regards to bidimensional simple coculture. The volume of gel drops was easily tunable to fit in 96-well plates. The cytotoxicity of D-Mannitol and its impacts on the microvascular network were evaluated, as an example of the pertinence of this 3D BBB capillary model for screening applications.

Abstract
Flooding is one of the biggest natural disasters that occurs frequently around the world. It can occur without warning and the after effect of it leaves great damage to the surrounding environment and exposes life threatening to citizen. Therefore, early flood detection and monitoring system with the implementation of Internet of Things and Global Positioning System is proposed in order to reduce the risks that may cause flooding. The aim of this project is to provide the information of a current water level in a drain. When water level increases to a certain level, the system will send a warning notification to users indicating three categories of water level, which are safe, warning and critical level. This system contains an ultrasonic sensor to detect the current water level and at the same time allows users to observe the period of the water level from their phone so that users are more aware of when flooding ought to happen. Moreover, the system consists of a flooding avoidance method that requires the usage of a solenoid as a shutter valve of the drain and water pump to pump out excessive water flow to a suitable place for water release purposes.

Abstract
Artisanal gold mining (ASGM) commonly found in Indonesia, particularly in Banyumas, Central Java, which is still processing the gold ore by using mercury. The objective of this study to examine the concentration and mobility of mercury contamination on the soil in the study area and to investigate the potential use of natural zeolite for stabilization mercury in contaminated soil. The soil samples were obtained from the top layer and subsurface and then analyzed for mercury concentrations and mobility. Soil stabilization experiment was conducted by using natural zeolite from Gunungkidul, Yogyakarta and the effects of natural zeolites in the reduction of the concentration of mercury was investigated by assessed Jatropha curcas plant. The result shows that the higher mercury concentration was found in topsoil rather than the subsurface. The result of mobility analysis shows that most mercury fractions are associated with organic mercury followed by mercury element fractions. Soil stabilization experiment revealed that adding natural zeolites as soil additives will reduce the concentrations of Hg in plant material which of the important point leading to the entry of mercury into the food chain.

Published: July 2020

Abstract
Disaster Risk Index (DRI) is a tool for risk identification, risk management and risk exposure which measured at a different level of scales such as global, regional, trans-boundary or local. This paper reviews DRI and its developments at a local scale of nine countries. There are differences in the risk index components used. Some countries from the previous study such as China, Indonesia, Philippines, USA, and Brazil applied World Risk Index (WRI) concept while others use a combination of other risk components to define risk. The paper also reviews the methodologies used in terms of indicators’ weight and the purpose of DRI development. The vulnerability component, which divided into six dimensions for assessment (social, environmental, economic, institutional, physical and economic) mostly focused on the social and physical dimensions. There is a limitation for the WRI concept at the local level in terms of data availability. The indicator used does not represent the local attribute of the countries or the community. Greater focus placed on an integrated approach for the development of DRI at the local level by considering the element of climate risk as an indicator. The development of DRI should consider an integrated approach that is focused on a certain dimension for future research for contribution to Disaster Risk Reduction (DRR).

Abstract
Greenhouse effect is the serious environmental issue whereby the gaseous component involved is dangerous. One of the gases that contributed to atmosphere is carbon dioxide (CO2), in which is more than 80%, followed by methane and nitrous oxide that resulted from human activities, industrial sector and transportation. Activated carbon (AC) is the best adsorption technology due to simple design and ability to capture carbon dioxide efficiently. This paper was aimed to produce activated carbon derived from waste material, to determine adsorption rate at different pressures and temperatures and to relate adsorption kinetics and isotherms equilibrium to describe adsorption processes. Palm Kernel Shell (PKS) was selected as raw material to produce AC. Char was produced via carbonization process at 700 °C ± 20 °C for 2 h with 10 °C/min heating rate under inert gas flow. The sample is then grinded and sieved to 0.65mm to 0.8mm, followed by chemical treatment by using potassium hydroxide with ratio of 1:1 and directly undergoing microwave treatment. Adsorption rate performances were investigated by different temperatures of 25 °C and 10 °C and pressures of 5, 15 and 25 bar. The sample were characterized by thermo-gravimetric analysis, surface area analysis, and ultimate analysis. AC-PKS shows the highest surface area. As a result, increase in pressure led to increase in CO2 adsorption while decrease in temperature in CO2 adsorption. In conclusion, the findings revealed that the potential of AC-PKS to capture CO2 in order to enhance environmental sustainability and economically.
