Science in A Black Box: Can Teachers Address Science from Socio-Scientific Issues?
Authors: Erman E , Sari D A P 
Published: December 2019

Abstract
This study aims to determine teachers’ ability to address science from socio-scientific issues (SSI) as predictors of scientific literacy that consider as a black box in schools. A total of 25 junior high school science teachers in some areas of East Java volunteered to be involved in this survey. Data collected by addressing macroscopic issues (AMI) tests and questionnaires were analyzed descriptively through content analysis and percentage. The results indicate that science teachers generally have difficulty in addressing science from SSI. The authentication worksheet shows that almost all AMI that can be addressed only reaches 50% maximum. Less than 50% of science teachers have heard of scientific literacy but have not been able to describe it. The implication, the student may not become a scientifically literate person if teachers are not scientifically literate, and SSI is not involved in the learning process.

Study on the surface ceramization of aluminum alloy
Authors: Wu Zhifu , Hu Liyun 
Published: December 2019

Abstract
Aluminum alloy has been widely used as a metal material. However, it is usually vulnerable to corrosion, so the protection of aluminum alloy surface is particularly important. At present, the commonly used methods of surface protection of aluminium alloys are anodic oxidation, plasma micro-arc oxidation, chemical oxidation and so on. In this experiment, chemical protective coatings were prepared by chemical oxidation of Aluminium 1100 and 6063 treated with H2O2 or KMnO4 solution. The results showed that the oxidation capacity of H2O2 solution from 3% concentration to 15% concentration to Al1100 was successively enhanced. Moreover, the ceramic coating produced when the concentration of H2O2 is 12%-15% has a better effect, and the structures are cauliflower, concave and convex, and hydrophobic. It is expected that the surface has lotus leaf effect.

Research of Chinese Government debt sustainability and its effect on economic growth
Authors: Li Jifan 
Published: December 2019

Abstract
This paper researches the appropriate scale of Chinese government debt from the perspective of debt sustainability and its effect on economic growth. First, we made a model based on fiscal response framework and introduced trade openness, savings ratio and so on as control variables. We use it to measure the upper limit of the sustainable debt ratio over the years. Then we did empirical research and found that government debt has a threshold effect on economic growth, with a turning point of about 33.3%. Besides, we also found that debt affects economy by affecting the formation of total society capital significantly, and excessive debt may inhibit the formation. According to our research, the government should release savings reasonably, improve its sensitivity to debt and use it more efficiently to enhance the turning point of debt impact. Government should also gradually reduce current debt ratio to optimize the relative scale of debt.

Abstract
In order to study the effect of feeding Ginkgo leaf fermentation and Chinese herbal medicine on meat duck, we added Ginkgo leaf fermentation and Chinese herbal medicine additive to the daily feed of meat ducks, and set up a control group (basic feed), a western medicine group (basic feed+150mg/kg aureomycin), an experimental group 1 (basic feed + Chinese herbal medicine 0.1%) and an experimental group 2 (basic feed + 0.1% Chinese herbal medicine + 2.5% Ginkgo leaf ferment). We fed the ducks for 45 days, and then completed the measurement of production performance and blood index. Based on the measurement method of related data, we used Excel and spss25 software for data statistics and analysis. The results showed that the diet supplemented with 0.1% Chinese herbal medicine and 2.5% Ginkgo leaf fermentation could significantly increase daily growth weight of meat ducks during the whole growth period (P<0.05), at the same time, it could reduce feed conversion ratio, and the content of total protein and albumin in serum could be significantly increased (P<0.05). The value of alkaline phosphatase in the experimental group was lower than that of the control group. The amount of immunoglobulin and complement in the serum were all higher in the experimental group than in the control group. The overall effect of Ginkgo leaf fermentation and Chinese herbal medicine in basic diet was significantly better than that of western medicine group (P<0.01).

Performance of Bundle Protocol (BP) for deep space communications with long link disruptions
Authors: Wang Ding , Yu Hongzhi 
Published: December 2019

Abstract
Near Earth missions and deep space missions will continue to be a major future space mission. A long link disruption is inevitable in space communications because of spacecraft rotation, planetary bodies and limited relay capability. A few works have been done with delay/disruption tolerant networking (DTN) technology for deep space communications and provided feasibility for its adoption in LEO- space and deep space missions. However, not much work has been done to fully evaluate the performance of DTN in such an environment, especially in the presence of custody and long link transfer. In this article, we present an experimental performance evaluation of DTN architecture and protocol stack with DTN custody transfer and long link break underneath bundle protocol (BP), in typical LEO-satellite and deep space communication infrastructures accompanied. The experiment was conducted by performing realistic file transfers over a PC-based test-bed.

Published: December 2019

Abstract
Urban form in both two- (2D) and three-dimensions (3D) has significant impacts on local and global environments. Here we developed the largest global dataset characterizing 2D and 3D urban growth for 478 cities with populations of one million or larger. Using remote sensing data from the SeaWinds scatterometer for 2001 and 2009, and the Global Human Settlement Layer for 2000 and 2014, we applied a cluster analysis and found five urban growth typologies: stabilized, outward, mature upward, budding outward, upward and outward. Budding outward is the dominant typology worldwide, per the largest total area. Cities characterized by upward and outward growth are few in number and concentrated primarily in China and South Korea, where there has been a large increase in high-rises during the study period. With the exception of East Asia, cities within a geographic region exhibit remarkably similar patterns of urban growth. Our results show that every city exhibits multiple urban growth typologies concurrently. Thus, while it is possible to describe a city by its dominant urban growth typology, a more accurate and comprehensive characterization would include some combination of the five typologies. The implications of the results for urban sustainability are multi-fold. First, the results suggest that there is considerable opportunity to shape future patterns of urbanization, given that most of the new urban growth is nascent and low magnitude outward expansion. Second, the clear geographic patterns and wide variations in the physical form of urban growth, within country and city, suggest that markets, national and subnational policies, including the absence of, can shape how cities grow. Third, the presence of different typologies within each city suggests the need for differentiated strategies for different parts of a single city. Finally, the new urban forms revealed in this analysis provide a first glimpse into the carbon lock-in of recently constructed energy-demanding infrastructure of urban settlements.
Increasing occurrence of heat waves in the terrestrial Arctic

Published: December 2019

Abstract
Heat waves in the Arctic may strongly impact environment and local communities. Recently several indices have been proposed for monitoring environmental changes in the Arctic, but heat waves have not been addressed. By applying a structured approach for evaluating occurrences of periods with exceptionally high temperatures, this study demonstrates that in the last decades there was an increase of heat wave occurrences over the terrestrial Arctic. The increase is mainly over the Canadian Arctic Archipelago and Greenland that are surrounded by ocean undergoing a sea-ice melting trend, while the Eurasian Arctic shows no significant change in heat wave occurrence. Since 2002 the probability of experiencing heat waves in the Arctic has been similar or even higher than in the middle and low latitudes and heat waves have already started to increasingly threaten local vegetation, ecology, human health and economy.
Impact of Atlantic water inflow on winter cyclone activity in the Barents Sea: insights from coupled regional climate model simulations
Authors: Akperov Mirseid , Semenov Vladimir A , Mokhov Igor I , Dorn Wolfgang , Rinke Annette 
Published: December 2019

Abstract
The impact of the Atlantic water inflow (AW inflow) into the Barents Sea on the regional cyclone activity in winter is analyzed in 10 ensemble simulations with the coupled Arctic atmosphere-ocean-sea ice model HIRHAM-NAOSIM for the 1979–2016 period. The model shows a statistically robust connection between AW inflow and climate variability in the Barents Sea. The analysis reveals that anomalously high AW inflow leads to changes in static stability and wind shear in the lower troposphere, and thus favorable conditions for cyclogenesis in the Barents/Kara Seas. The frequency of occurrence of cyclones, but particularly of intense cyclones, is increased over the Barents Sea. Furthermore, the cyclones in the Barents Sea become larger (increased radius) and stronger (increased intensity) in response to an increased AW inflow into the Barents Sea, compared to years of anomalously low AW inflow.
