ABSTRACTParacrine and endocrine roles have increasingly been ascribed to extracellular vesicles (EVs) generated by multicellular organisms. Central to the biogenesis, content, and function of EVs are their delimiting lipid bilayer membranes. To evaluate research progress on membranes and EVs, the International Society for Extracellular Vesicles (ISEV) conducted a workshop in March 2018 in Baltimore, Maryland, USA, bringing together key opinion leaders and hands‐on researchers who were selected on the basis of submitted applications. The workshop was accompanied by two scientific surveys and covered four broad topics: EV biogenesis and release; EV uptake and fusion; technologies and strategies used to study EV membranes; and EV transfer and functional assays. In this ISEV position paper, we synthesize the results of the workshop and the related surveys to outline important outstanding questions about EV membranes and describe areas of consensus. The workshop discussions and survey responses reveal that while much progress has been made in the field, there are still several concepts that divide opinion. Good consensus exists in some areas, including particular aspects of EV biogenesis, uptake and downstream signalling. Areas with little to no consensus include EV storage and stability, as well as whether and how EVs fuse with target cells. Further research is needed in these key areas, as a better understanding of membrane biology will contribute substantially towards advancing the field of extracellular vesicles.

Abstract
Aviation emissions have been found to cause 5% of global anthropogenic radiative forcing and ∼16 000 premature deaths annually due to impaired air quality. When aiming to reduce these impacts, decision makers often face trade-offs between different emission species or impacts in different times and locations. To inform rational decision-making, this study computes aviation’s marginal climate and air quality impacts per tonne of species emitted and accounts for the altitude, location, and chemical composition of emissions. Climate impacts are calculated using a reduced-order climate model, and air quality-related health impacts are quantified using marginal atmospheric sensitivities to emissions from the adjoint of the global chemistry-transport model GEOS-Chem in combination with concentration response functions and the value of statistical life. The results indicate that 90% of the global impacts per unit of fuel burn are attributable to cruise emissions, and that 64% of all damages are the result of air quality impacts. Furthermore, nitrogen oxides (NO
x
), carbon dioxide (CO2), and contrails are collectively responsible for 97% of the total impact. Applying our result metrics to an example, we find that a 20% NOx stringency scenario for new aircraft would reduce the net atmospheric impacts by 700 m USD during the first year of operation, even if the NO
x
emission reductions cause a small increase in CO2 emissions of 2%. In such a way, the damage metrics can be used to rapidly evaluate the atmospheric impacts of market growth as well as emissions trade-offs of aviation-related policies or technology improvements.

Abstract
Due to several sources of potential variability associated with exhaled breath bag sampling procedures for off-line analysis, the Respiration Collector for in vitro Analysis (ReCIVA) sampler was developed. Although designed to improve upon several pitfalls of sampling with exhaled breath bags, the ReCIVA remains a minimally studied research tool. In this manuscript, several attributes of the ReCIVA sampler are investigated among three individual tests, such as background contamination, control software version, performance of different adsorbent tubes, duplicate sample production, and comparison to exhaled breath bags. The data shows greater than a 58% reduction in background siloxanes can be achieved with submersion of ReCIVA masks in ethyl alcohol or baking the masks at a high temperature (200 °C). The results illustrate the ReCIVA control software version plays a key role in the flow rates applied to thermal desorption (TD) tubes. Using exhaled isoprene as a representative analyte, the data suggest duplicate samples among ReCIVA pump banks can be achieved using two different thermal desorption tubes, Tenax TA and Tenax/Carbograph 5TD, when using an updated control software and manually calibrating the ReCIVA pumps to uniform flow rates (Tenax p = 0.3869, 5TD p = 0.3131). Additionally, using the updated control software and manual ReCIVA flow calibration, the data suggest the ReCIVA can produce statistically similar results among TD tube types (p = 0.3824) and compared to standard exhaled breath bags (p = 0.1534). Collectively, these results establish a method for manually calibrating the flow of the ReCIVA device to allow for the most consistent results. These data support further experimentation into the use of the ReCIVA sampler for exhaled breath research.
Application of BIM Technology in Calculation of a Residential Building
Authors: Li Shenya , Yu Yingxia 
Published: November 2019

Abstract
This article summarizes some disadvantages that arise when not using BIM technology modeling to make engineering budgets. For example, traditional calculations are calculated manually by using two-dimensional maps so that the efficiency is low, repetitive modeling rates are high by using general modeling software to modeling, and the reuse rate of the built model is low, the model is not built accurately, and the model information cannot be shared. All the above disadvantages lead to inaccurate calculation of the engineering, and in the whole process of construction of the engineering, the participants of each engineering cannot contact and coordinate the work closely, resulting in serious waste of resources and seriously harming the interests of all parties so that the construction progress of the project is seriously affected. However, using the model built by BIM calculation software to solve the above problems can effectively solve the above problems, and make a great contribution to the development and innovation of engineering cost.

Abstract
The construction land changes from 1994 to 2013 in Changsha-Zhuzhou-Xiangtan are monitored by using multi-period Landsat images in the paper. The characteristics and laws of construction land expansion in Changsha-Zhuzhou-Xiangtan are analyzed by using the construction land index of expansion speed, expansion intensity index, quadrant buffer analysis, and gravity transfer model. The results show that: (1) the construction land of Changsha-Zhuzhou-Xiangtan area increased linearly in the past 20 years. The construction land expansion area is the largest and the expansion intensity is the biggest in 2009-2013. (2) The construction land area showed a trend of accelerating expansion in the 8 quadrant direction between 1994-2013 years. The expansion direction occurs mainly in the seventh, third, fourth quadrant. (3) The urban gravity center shifted southward obviously in Changsha and moved fastest in Zhuzhou and slowest in Changsha.

Authors: Xiangdong Song , Chengsong Qu 
Published: November 2019

Abstract
The excavation of pit and the dewatering during the excavation leads to evident subsidence of surrounding buildings and structures. Groundwater recharge during the construction of Heyan-road-crossing-river-passage shows a clear subsidence inhibiting effect even though the work site is only 500 meters away from Yangtze River. Totally 217 recharge wells were arranged around the pit and the average recharge rate was about 2m3 per hour. The subsidence inhibiting effect of recharge can decrease the environment risk caused by pit construction.

Authors: Wu Cuifang , Yi Haiying 
Published: November 2019

Abstract
The entropy evaluation method was used to measure the urbanization system and water resources system respectively. The supporting capacity between urbanization and water resources was measured by using the compound coordination model. The research result showed that the supporting capacity of the water resources system to the new-type urbanization development of Gansu Province was continuously increasing from 2000 to 2013. But the overall supporting capacity of water resource system to new-type urbanization of Gansu Province showed a fluctuating declining trend from 2014 to 2017, indicating that the contradiction between new-type urbanization and water resources began to appear with the acceleration of urbanization construction. The supporting capacity of water resources in all regions of Gansu Province was at a low level and the supporting capacity of most regions was undesirable. The relationship between the supporting capacity of water resources in Gansu Province and time series showed a inverted U-shape curve. The supporting capacity of the future water resources will continuously decrease, indicating that the contradiction between new-type urbanization and water resources will be further upgraded.

Authors: Liu Yi , He Lizhen 
Published: November 2019

Abstract
In this paper, it is proposed to use electric fan to actively control the indoor gas flow field to improve the ability of an air purifier to capture PM2.5 and other fine particles. For this purpose, an indoor physical model formed by a room, an air purifier and an electric fan is established and the simulation software Fluent is used to simulate the gas flow field distribution and PM2.5 particle tracking. The control method of the electric fan based on periodic rectangular wave is adopted to control and maintain the steady and conducive indoor gas flow field distribution for gathering particle pollutants into the air purifier’s inlet. The simulation results show that the active control method of gas flow field can improve the purification speed and effectiveness of air purifier, and the simulation results are verified by actual test of the purification process of PM2.5 particles in an enclosed room. It provides an economical, practical and effective method to improve indoor air quality.

Published: November 2019

Abstract
In this study, to provide basis for postharvest storage, the effect of on-tree and indoor storage on fruit quality of three pummelo (Citrus grandis Osbeck) cultivars was evaluated. We compared the fruit quality by these two storage methods. For external fruit quality, peel thickness decreased significantly with the increase of indoor storage times. The granulation index of on-tree fruits reached the maximum value of 0.63 in ‘Hungjinmiyou’ for 90 days. After 90 days for on-tree storage, three pummelo cultivars started to reveal storage taste. The remaining index such as weight per fruit, fruit shape index, segment and edible rate revealed no obvious change trends between on-tree and indoor storage methods. There were no obvious change trends in the content of total soluble solid, reaching the maximum value of 11.12%, 10.87%, and 11.17% for 60 or 90 days for on-tree storage. While for indoor storage, TSS content revealed a decrease - rise - decrease trend. Vitamin C and sugar contents decreased with the increase of on-tree storage times. The flesh chromatism of on-tree fruits turned to light red in ‘Sanhongmiyou’ and ‘Hongroumiyou’, while it kept stable with orange- yellow in ‘Huangjinmiyou’. Taking external and internal fruit quality into consideration, it is better to store for 90 days on-tree and indoor for ‘Sanhongmiyou’ and ‘Hongroumiyou’, 60 days for ‘Huangjinmiyou’, respectively. By comparison, fruits on-tree storage showed better quality than that by indoor storage.
