Authors: Xie Jiemin , Zhang Jun , Xie Xuan , Bi Zhiwei , Li Zhuoheng 
Published: December 2019

Abstract
Tree based ensemble learning algorithms involve generating multiple trees that together produce a consistent prediction and often significantly improving the accuracy of the prediction. In this paper, the technique is further explored, and a dam displacement prediction model based on bootstrap aggregating (bagged) regression trees (BART) is proposed. The case study of concrete dam indicates that the performance of bagged regression trees is better than the conventional regression tree (RT) model in predicting dam displacement. Moreover, the model can also analyze the importance of each variable, which has strong practical value.

Authors: Gao Zengrong 
Published: December 2019

Abstract
The purpose of this research is based on the placement of two geographically opposed cities, but with similarities in their urban structure, Dalian and Paris. We study here the design strategies involved in the emergence of contemporary urban public spaces, in the metropolitan context, and in a globalized context of urban identity research. First, we compare the status of public space in the two different cultural and urban contexts of China and Europe. Then, we enter in the analysis of examples of two main elements of urban composition: the public square and the metropolitan axis. By the first, we put our analysis on the example of Zhongshan Square, a singular but not unique case in the Chinese city the most provided in places that is Dalian. Then, concerning the metropolitan axis, we focus our study on the Champs-Élysées, allowing us to reveal the great axis of Dalian constituted by the succession of broad streets between Qingniwa and the Donggang Center. We conclude our study of the Parisian examples of the Beaubourg plateau and Les Halles, which show both perspectives and models of conceptions of public spaces that follow and bring urban progress, in our contemporary and globalized cultural and historical context.

Published: December 2019

Abstract
The sand layer of the floodplain area near Yangtze River is thick and rich in water content. It is difficult to cut off the groundwater hydraulic connection inside and outside the pit with anti-water curtain. Hence, it is necessary to determine the depth of the pensile curtains rationally and economically. The three-dimensional motion model of groundwater can effectively simulate the dewatering and provide a basis for the selection of the depth of the pensile curtains. Reasonable dewatering-recharge arrangement is cost-saving and time-saving. Its good economic and social benefits demonstrate the feasibility in follow-up construction.

Published: December 2019

Abstract
Pudu River is the largest tributary of the Jinsha River Basin in Yunnan Province, with a runoff area of approximately 11700 km2. The upstream is Dianchi Lake, and the flood forecasting has been less studied in Yunnan Province. The purpose of this paper is to do some flood forecasting research for downstream lead plant power stations based on the data conditions and relevant theories. According to the conventional flow algorithm, corresponding water level method and synthetic flow method, the flood of the downstream lead plant power station is forecasted, and the prediction accuracy of each method is evaluated. After analysis, the flow algorithm is not suitable for forecasting the flood of the lead plant, and the accuracy of the synthetic flow law is not high. Finally, the corresponding water level method is selected as the forecast method suitable for the local river section.

Abstract
Based on the investigated data from 2000 to 2015 that related to water resources utilization in 103 units about Water Resources Fourth Sub-Region divided by Drainage Basin overlying Prefecture (abbr. WRFSRDBP) in Yunnan Province that belongs to Yunnan – Guizhou plateau, Gini coefficient, Theil coefficient and Variation coefficient were adopt to evaluated equilibration on water resources utilization of the whole province. The results shows that the Gini coefficients about water resources utilization in the province was 0.105∼ 0.763, the average value was 0.544. Water supply quantity of reservoirs and ponds increased 3.033×109 m3 in recent 15 years, resulted in the Gini coefficient decreased from 0.327 to 0.256, namely the equilibration changed better; While the Gini coefficient of water supply quantity of projects by gravity channel, pump and trans-valley increased from 0.209 to 0.266, as new reservoir was built across river upstream, thus water supply amount was transferred to water supply amount of reservoir; Water supply by wells, rain collection and wastewater reused projects in different units changed various, the Gini coefficient of water supply by wells were 0.584∼0.614, and rain collection and wastewater reused projects were 0.611∼0.641 in the last 15 years, respectively. Non-cigarette industry developed rapidly, due to the restriction policy of state’s tobacco cultivate and cigarette plant, which promoted industrial structure changed from 2000. Those was the reason that the Gini coefficient of industrial water usages decreased from 0.542 to 0.329; Synchronously, the Gini coefficient of municipal water usage also decreased from 0.463 to 0.321, and the equilibration changed better too; On the other hand, the extent of water utilization different about livelihood and livestock in countryside was broaden, the Gini coefficient increased from 0.100 to 0.321; In recent 15 years, provincial irrigated rate of Yunnan was raised from 21.8% to 29.1%, the gap among sub-regions on agriculture irrigation development was reduced gradually, the Gini coefficient of irrigated water consumption decreased from 0.294 to 0.153 consequently. Ulteriorly, local entropy spatial distribution in the sub-regions revealed degree of importance of its water supply and water usage in the province. Besides, research by Theil coefficient and Variation coefficient also proved the same results.

Published: December 2019

Abstract
While traffic congestion issues has not be solved in Bangkok, Thailand, an intervention in order to improve air quality and reduce greenhouse gas emissions is required for sustaining the continuation of this urban problematic. Greening mobility in term of “Eco- Friendly Travel” is therefore the ultimate transport challenge towards sustainability that will significantly reduce greenhouse gas emissions of existing unsolved land transport. Facing this global sustainability challenge arises the need to adopt an environmental friendly mobility culture by using participatory approach to integrate with technologies and fuel options for water transport system. This study was conducted based on a concise analysis of the current geography of canal network in Bangkok along with an introduction of “canal transit” to ask respondent of 1,200 sets from residents around the Lat Phrao canal which is one of the most potential canal in Bangkok. The results revealed its feasible option for local transport in terms of urban connectivity improvement and community-owned resources. However, it needs various improvements such as accessibility, transit services, urban activities spaces, and community activities and value-added transportation services which would be the keys to success to increase local economic competencies and sustaining water transport in Bangkok.
Environmental impact of private forest management in Central Lombok, West Nusa Tenggara
Authors: Nandini Ryke 
Published: December 2019

Abstract
Community forestry has several impacts on the environment, both physical and social economics. This study aims to determine the environmental impacts of private forest activities in Central Lombok, especially on runoff and soil erosion. The hydrological modelling approach operating Soil and Water Analysis Tools (SWAT) was used to describe the hydrological response such as runoff and soil erosion that occurs as the impacts of private forests. The results revealed that runoff and soil erosion observed in 2008-2014 had the same trend, with a polynomial pattern that increases at the beginning of the measurement and drops at the end. It means that the longer the age of the private forest, the higher runoff and soil erosion will be reduced and the better the quality of the environment. Thus, intensive private forests need to be development to improve environmental quality.
A review on the floating net cage waste management for the sustainability of Cirata Reservoir service life
Authors: Suryawan A , Sunardi  , Heru B 
Published: December 2019

Abstract
The number of Floating Net Cages (FNC) in Cirata reservoir has exploded four times more than allowed. It makes water quality problem severe because 22.260 tons/month of stools and excessive feeding threaten the benefits, functions, and service life of the reservoir. This is a review paper to explore FNC waste management methods, the potential of integrated FNC management, and the implementation strategies. Twenty-eight articles published between 2015 and 2019 abaout aquaculture technology have been discussed to improve understanding of FNC waste management. Several solutions have been recommended based on an integrated management approach. Technical ideas are proposed for water control and in situ treatment management. Management of water control reduces the concentration of pollutants by increasing water destratification. The IFCAS (Integrated Floating Cage Aquageoponics System) - PFF (Precision Fish Farming) - IMTA (Integrated Multi-Trophic Aquaculture) concept is an effort to manage FNC using both approaches. The IFCAS-IMTA concept can reduce the main concept of waste by creating the nitrification and assimilation of phosphate. The concept of PFF can improve the capacity of farmers in water quality detection and monitoring. The manager needs to modify aquaculture techniques in water and nutrition, feeding formulations, technological innovations, and the inclusiveness of scientific-based management. Management must involve FNC farmers, research and development institutions, Cirata authorities, Fisheries and Marine Service of West Java Province, and investors.

Authors: Efadeswarni  , Andriantoro  , Azizah N , Saragih G S 
Published: December 2019

Abstract
Microplastics are small plastic particles less than five millimeters in size. Microplastic is dangerous because it becomes a medium for other pollutants such as heavy metals and harmful bacteria to attach on. This study aims to determine the presence of microplastic in the digestive tracts of fishes in Jakarta Bay. The number of fish samples obtained was 25 fishes consisting of several species, namely, Siganus sp., Albula forsteri, Lutjanus sp., Parastromateus sp., Plicofollis argyropleuron, Pampus argenteus, Paraplotosus albilabris, Sardinella fimbriata, and Platycephalus indicus. The samples were grouped into three categories based on the length of their body, namely small fish with a length of 13-24 cm, medium fish 25-36 cm, and large fish 37-90 cm. The method used to identify microplastics in the fishes digestive tract is optical microscopy. Microplastics were found in 19 fish (76%), those identified as fiber is 73%, identified as films is 18%, and identified as fragment 9%. The larger the size of fish the higher the microplastic content of all types. This implies that microplastic bioaccumulation occurs through the food chain.

Authors: Syofyan Y , Andiri Y , Kartiningsih S E , Ratnaningsih D 
Published: December 2019

AbstractOrganochlorine compounds (OCs) are widely used as pesticides in the past and several of them have been prohibited. Some of these organochlorine compounds have persistent properties that can last long in the environment so that they have been included in the list of groups of persistent organic pollutants (POPs). The bioconcentration and bioaccumulation properties of organochlorine compounds increase the negative impact on the health of living organism. The purpose of this study was to measure the organochlorine compounds in the environment, including samples from agricultural soil, sediment, and river water. Sampling was collected in November and December 2018. Sample of agricultural soils were taken in Bogor and Cianjur regencies while water and sediment samples were taken from the rivers in the Jakarta and Cianjur regencies. Total of 24 organochlorine compounds were then measured using Gas Chromatography Mass Spectrophotometer (GCMS). Recovery of water samples was 72% to 82%, for the soil was 79% to 103% and for sediment was below 40%. The OCs detected in the water was in the range of 0.010 µg/L – 0.4 µg/L and in the soil was in the range of 0.4 µg/Kg – 18.55 µg/Kg. Measurement of OCs in sediments from the estuary or downstream of the river in Jakarta was done, however the result was uncertain due to the difficulties in the sample preparation of oily sediments, and hence the results were not provided here. Therefore, it was necessary to develop a testing methodology, especially the proper refining process so that good recovery data could be obtained in the future. The small amounts of organochlorine that were detected in the environment indicated that these compounds are still existing up to now. The purpose of this study is to produce the proper methodology to examine the matrix effects from sticky and oily samples.
Bird community changes across gradient of habitat quality in the urban green open space
Authors: Mardiastuti A 
Published: December 2019

AbstractBird species can be found in almost all habitat types, including urban area. The objective of this research was to investigate the changes in bird community in different habitat quality gradients of urban green open spaces and provide suggestions for indicator species. Five urban green open spaces were selected as study sites, representing gradient from low to high habitat quality: Gunung Gadung cemetery (21 bird sp.), Sentul City (34 sp.), Bogor Botanical Garden (48 sp.), Darmaga Campus (52 sp.), and Darmaga Experimental Forest (35 sp.). Species richness and Jaccard similarity indices were analyzed to discover the pattern reflecting the quality of urban habitat. Bird community in all study sites had low to medium similarity (0.33-0.51), indicating that each site had a distinct bird community. Bird richness was highest in the mid-quality habitat (garden-tree mix), but decreased in the high quality (urban mature forest). Bird that can be used for habitat indicators were babbler (low-medium quality); bulbul, pigeon, flycatchers (medium-quality); pied triller and cuckoo (medium-high quality), and barbet and nuthatch (high quality). Similar research needs to be conducted in other urban areas to reconfirm this pattern, in order to use bird community as an indicator of urban habitat quality.

Authors: Suryatmojo H , Putra G M , Satriagasa M C 
Published: December 2019

Abstract
Merawu watershed is located at Banjarnegara district and categorized as degraded watershed in the Serayu river basin. Upstream area in the Merawu watershed is a mountainous area of 1,500 m a.s.l., with steep slopes and high rainfall intensity. Upstream Merawu has an important function as recharge area, protect the downstream and water supply for the Merica reservoir. Forest conversion to intensive farming practices have produced large portion of erosion, surface runoff and water pollutant. Understanding the surface runoff changes in the forest conversion to intensive farming practices is important. Investigations of direct runoff in the intensive farming system in upstream area of Merawu watershed were observed using two small catchment experiments. Catchment for intensive farming system was compared to non-disturbed catchment of Pine forest. Surface disturbances associated with soil tillage, fertilization, pesticides and mulching during 2-3 months of planting reduced the soil capacity to control rainfall. During 1-year investigation, total direct runoff (DRO) in intensive farming catchment was 360.05 mm or 34.4% of rainfall or 1.63 times higher than that in the Pine forest catchment. Unit hydrograph analysis found the direct runoff coefficient was 9.4% or 1.7 times higher than that in the Pine forest catchment. This study found the important function of canopy interception, forest floor interception, soil management and infiltration to control the direct runoff in the catchment.

Abstract
Double perovskites, which can host two different transition metal cations at the B-sites of its perovskite derived structure, provide the possibility to explore the interplay of localized 3d transition metals and the relatively delocalized 4d or 5d transition metals within the same structure. This interplay gives rise to extraordinary magnetic properties. In this overview article, we summarize our recent computational efforts in understanding the curious properties of magnetic double perovskites with 3d and 4d/5d transition metal ions, make predictions on new functionalities in known compounds of this family, engineering functionalities via chemical modifications/doping and prediction on a new set of magnetic 3d-4d/5d double perovkite compounds, which may be synthesized to explore and expand further this interesting family.
Quasi-static compression characterization of binary nanoclay/graphene reinforced carbon/epoxy composites subjected to seawater conditioning
Authors: Ahsan Mohammad Al , Hosur Mahesh , Tareq Sarower Hossain , Hasan S M Kamrul 
Published: December 2019

Abstract
Fiber reinforced polymer composite (FRPC) materials are superior to other conventional materials because of their high strength to weight ratio, corrosion resistance, and moisture resistance. FRPC materials are preferred in many high-end applications such as marine, automobile, aerospace, and advanced sporting goods. The aim of this study was to investigate the in-plane quasi-static compressive and durability studies of nanophased FRPC materials. Composite samples were fabricated using unmodified epoxy and epoxy modified with montmorillonite nanoclay (MMT), graphene nanoplatelets (GNP), and a combination of the two as a binary reinforcement with carbon fibers. Quasi-static compression tests were conducted for mechanical property evaluation. Seawater conditioning was performed for a six-month period both at room and arctic cold temperatures. The results indicated that addition of GNP and MMT improved the compressive properties of carbon/epoxy composites compared to unmodified carbon samples. Specific compressive strength and modulus of GNP infused samples improved by 30 and 41% respectively; the samples showed a relatively higher strain to failure than the unmodified samples. Specific compressive strength and modulus increased by 32 and 47%, respectively, for carbon/epoxy samples with MMT reinforcement. Performance of hybrid carbon/glass/epoxy composites was lower compared to other FRPC materials considered in the study. The mode of failure of fractured samples investigated using scanning electron microscopy (SEM) showed a rough morphology after incorporation of nanoparticles into the polymer matrix. This is indicative of enhanced interfacial bonding between carbon/epoxy and the nanoparticles.
The Racialization of International Law after the Haitian Revolution: The Holy See and National Sovereignty
Authors: Gaffield Julia 
Published: December 2019

Abstract
The Haitian state shaped international definitions of sovereignty and national legitimacy after the Declaration of Independence in 1804. Haiti’s nineteenth century was not a period of isolation and decline; its first six decades were globally connected because the country’s leaders challenged their postcolonial inequality with diplomacy and state formation. This strategy aimed to establish Haiti’s membership in the “family of nations,” a central metaphor in European and American diplomatic, legal, and religious decision-making. In doing so, the Haitian state forced the Atlantic powers to redefine the boundaries of international relations. Haiti’s decades-long negotiations with the Catholic Church were tied to the racialization of the global hierarchy. After its Declaration of Independence, the Haitian state began clearing a theoretical path toward recognized sovereignty based on the dominant narrative that a society must be considered “civilized” on the world stage. But, as it cultivated internal policies and practices that rejected the dominant racist assumptions, these discriminatory ideologies became increasingly more explicit in international law.
Complexity measures of the mature miRNA for improving pre-miRNAs prediction
Authors: Raad Jonathan , Stegmayer Georgina , Milone Diego H 
Published: December 2019

Abstract

Motivation
The discovery of microRNA (miRNA) in the last decade has certainly changed the understanding of gene regulation in the cell. Although a large number of algorithms with different features have been proposed, they still predict an impractical amount of false positives. Most of the proposed features are based on the structure of precursors of the miRNA only, not considering the important and relevant information contained in the mature miRNA. Such new kind of features could certainly improve the performance of the predictors of new miRNAs.

Results
This paper presents three new features that are based on the sequence information contained in the mature miRNA. We will show how these new features, when used by a classical supervised machine learning approach as well as by more recent proposals based on deep learning, improve the prediction performance in a significant way. Moreover, several experimental conditions were defined and tested to evaluate the novel features impact in situations close to genome-wide analysis. The results show that the incorporation of new features based on the mature miRNA allows to improve the detection of new miRNAs independently of the classifier used.
