Renewable and sustainable energy has an evolving story as the ongoing trade war in the word is influencing crude oil prices. Moreover, the global warming is an inevitable consequence of the worldwide increasing rate of fossil fuel utilization which has persuaded the governments to invest on the clean and sustainable energy resources. In recent years, the cost of green energy has tumbled, making the price of renewables competitive to the fossil fuels. Although, the hydrogen fuel is still extremely expensive compared to the crude oil price, investigations about clean hydrogen fuel production and utilization has been developed significantly which demonstrate the importance of the hydrogen fuel in the future. This article aims to scrutinize the importance of green hydrogen fuel production from solar/wind energy.
随着全球正在进行的贸易战影响原油价格,可再生能源和可持续能源的故事也在不断发展。此外,全球变暖是世界范围内化石燃料利用率增加的必然结果,这促使各国政府投资清洁和可持续的能源资源。近年来,绿色能源的成本大幅下降,使可再生能源的价格与化石燃料具有竞争力。尽管与原油价格相比,氢燃料仍然非常昂贵,但清洁氢燃料的生产和利用研究已经取得了显著进展,这表明了氢燃料在未来的重要性。本文旨在探讨太阳能/风能绿色氢燃料生产的重要性。

This report emphasizes the non-aeronautical revenues of airports that are playing an increasingly important part in the revenues of airport. This report delves into different fields of non-aeronautical services that serve as an important revenue source as well as how to better manage these fields to bring greater profits and incomes for the airport. This report focuses on airport advertising, food and beverage and airport car parking as to their potential benefits and threats to the revenues of different airports. It shows that although these fields of non-aeronautical services can potentially bring in a lot of revenues and profits to the airports, different airports also need to adopt proactive policies and strategies to improve these fields to increase their revenues and competitiveness.

With the rapid increase of the construction volume of our country's landscape industry, the scale of the stock gardens is getting larger and larger. Later gardening maintenance technology needs to be constantly updated, and management modes and methods should be constantly innovated to meet the development needs of the maintenance market. The quality of maintenance and management in the later stage of green space construction is intuitively presented to the viewers through the quality of landscape. Therefore, improving the quality control ability of green space is the most important thing for the rapid development of garden enterprises. This paper combines the Internet with traditional maintenance quality management through Internet thinking, and achieves several important points in quality control, such as planning, traces, inspection, reporting and customer service evaluation, on the Internet management and control platform. Among them, the work plan combined with the maintenance calendar, the climate and soil and other environmental data from all parts of the country can better guide the field work; Maintenance trace record can provide data feedback through pictures, videos, etc.; Patrol function discovers green space problems in time, records data of basic problems of green space and feedback processing; And reporting function can provide customers with more convenient maintenance services. The addition of customer evaluation forms an important closed-loop for staff management and site quality from the perspective of customers. To some extent, this study solved the problems of insufficient quality standards and low efficiency under the traditional maintenance management mode, which accords with people’s service demand for greening maintenance at the present stage, and helps to enhance people’s recognition of greening personnel. With the help of Internet management and control thinking, we can better solve the pain points existing in the development of maintenance enterprises, provide new tools for the better development of maintenance industry, and lay a foundation for the growth of maintenance industry.

Hydrodynamic Effect on the Iso-octane Steam-Reforming in a Monolithic Reactor Channel 单片反应器通道内异辛烷蒸汽重整的水动力效应
Pub Date : 2019-08-30 DOI: 10.30564/jmser.v2i1.599

The production process of clean hydrogen by iso-octane steam reforming in a micro-reactor under atmospheric pressure, and the high temperature was investigated. The simulation is modeled using momentum conservation, mass conservation, and convection-diffusion equations, represented by the Navier-Stocks equations, the continuity equation, and the Steffan-Maxwell equation respectively. The resolution was performed using the COMSOL Multiphysics 3.5a software. This discretizes the differential equations into their conservative form by the finite element method using an unconditionally stable scheme. An analysis of the hydrodynamics of the flow effect shows that the hydrogen produced by iso-octane reforming is proportional to the mixed flow Reynolds number.

Public transport coverage fails to keep pace with urbanization and urban expansion, which makes the “last kilometer" problem of residents’ travel increasingly prominent”. However, the practice has proved that microcirculation public transportation plays an important role in expanding the coverage of public transportation and promoting the integration of public transportation. Therefore, this paper takes a city bus community as an example. Firstly, it analyses the bus travel demand of commuters connecting to the subway station during the early workday rush hours on basis of IC Big Data, obtains candidate stations of microcirculation bus lines through K-means clustering. Secondly, it establishes the model, the target of which is to minimize  the cost residents' travel and bus operation, under the limited condition of walking distance, passenger number, station spacing and departure frequency. Finally, the genetic algorithm is used to find the optimal solution of the model, so it’s no doubt that the most feasible circular bus route is obtained. The results have positive significance for promoting the construction and operation of public transport integration and promoting the convenience and efficiency of public transport travel. 
公共交通覆盖跟不上城市化和城市扩张的步伐,使得居民出行的“最后一公里”问题日益突出。然而,实践证明,微循环公共交通在扩大公共交通覆盖面、促进公共交通一体化方面具有重要作用。因此,本文以某城市公交社区为例。首先,以IC大数据为基础,分析工作日早高峰通勤者到地铁站的公交出行需求,通过K-means聚类得到微循环公交线路候选站点;其次,在步行距离、客流量、站距、发车频率有限的条件下,建立以居民出行和公交运营成本最小为目标的模型。最后利用遗传算法求解模型的最优解,得到最可行的环形公交路线。研究结果对于促进公共交通一体化建设和运营,促进公共交通出行的便利性和高效性具有积极意义。

The main objective of this study is to generate accurate synthetic hourly solar radiation data by using an easily accessible open source data. In this regard, a new approach is proposed for estimation of synthetic hourly global solar radiation during the day by utilizing only annual solar energy data. First time in literature, a model has been developed for prediction hourly and daily solar radiation based on annual solar energy parameter in this study. Parameters of the model were generated and tested for Turkey and one of them was presented as a case study within this paper. Long term measured hourly horizontal solar irradiance data from a network of Turkish meteorological stations was used to calibrate the model function. The predictions are compared with the solar data available in literature for Turkey. The advanced simple new model is utilized in open source computer program and has the potential to be adapted to other countries.

Surfactant/alkali flooding is one of the best chemical flooding methods to enhance oil Recovery Factor (RF). In this research, Ionic Liquid/Alkali (ILA) mixtures were chosen to address the chemical injection technique. The selected Ionic Liquids (ILs), [EMIM][Cl], [THTDPH][Cl], [EMIM][Ac], [BzMIM][Cl], [DMIM][Cl], [BzMIM][TOS], [dMIM][TOS] and [MPyr][TOS], were introduced to investigate their efficiency in improving the extraction of heavy oil (14o API) from an unconsolidated sand pack at room conditions. Second, these ILs were mixed with synthetic formation brine (3.37 wt. % salts)/alkali (Sodium Bicarbonate [NaHCO3]). Then, 1 Pore Volume (PV) of these composites were injected and flushed with 2 PV of formation brine. The study discussed the influence of cation type, anion type, the structure of the ILs, and the effect of combining ILs and alkali on the RF. The results revealed that these ILs are efficient chemicals for enhancing the RF. ILs with shorter alkyl chain and more aromatic rings are noticeably efficient in enhancing the RF. Finding the right composition ([DMIM][Cl] + NaHCO3) of the chemical slug could increase the additional RF up to 31.55 (% OOIP). The recovery factor results supported by the effects of IL types on the viscosity, Surface Tension (SFT), and Zeta Potential (ZP) supported.

The current situation of Cairo metro stations, especially terminal stations and its surrounding areas, has bad financial revenue and bad effect on environment. It is a major factor in increasing of noise, traffic jam and air pollution, in addition to, spreading of street vendors, collecting of random parking around these terminal stations. Thus, this paper proposed a methodology helping to apply multilateral investments in metro terminal stations for getting extra profits and decreasing the bad environmental effect of terminal stations and its surrounding areas. Hence, Helwan-Metro station on line 1 has been considered as a case study. Number of passengers at peak time, their ages, and their destinations, have been considered by making a field survey and a questionnaire. After collecting data and finalizing the surveying questionnaire, primary studies were done to modify and introduce a new proposal for Helwan-Metro station. The initial cost of the proposed project is predicted by using Artificial Neural Network technique using Just NN software. The investment feasibility achieved by consideration of Life Cycle Cost analysis and calculation of Net Present Value (NPV) of the proposed project.
开罗地铁车站,尤其是终点站及其周边地区的现状,不仅财政收入不佳,而且对环境的影响也很严重。这是一个主要因素,噪音增加,交通堵塞和空气污染,此外,摊贩的蔓延,收集随机停车在这些终点站周围。因此,本文提出了一种有助于在地铁终点站应用多边投资的方法,以获得额外的利润,并减少终点站及其周边地区的不良环境影响。因此,1号线赫尔湾地铁站被认为是一个案例研究。通过实地调查和问卷调查,考虑了高峰时段的乘客人数、年龄和目的地。在收集数据和完成调查问卷后,对赫尔万地铁站的新方案进行了初步研究。采用人工神经网络技术,利用Just NN软件对拟建工程的初始成本进行预测。通过对拟投资项目的全生命周期成本分析和净现值(NPV)计算,得出投资的可行性。

The prediction of formation pore pressure and fracture pressure gradients is a significant step towards the drilling plan. In this study, the formation pressures of twelve wells from NC98 field-Sirte Basin (Waha Oil Company) were calculated by employing empirical methods, Eaton’s equations, that depend on the real drilling and well-logging data. Regarding the results, the normal pore pressure in the NC98 field in Sirte basin is 0.437 Psi/ft, and it is extending from the top of the wells in the investigated area to 7,000 ft. A subnormal to normal pore pressure zone is noticed in the interval of 7,000 ft. to 9,000 ft. Then, slightly subnormal to somewhat abnormal (overpressure) region is seen from 9,000 ft. to 11,200 ft. Beyond to that depth and down to the top of the reservoir, the overpressure zone was clearly observed. Based on the results, the casing setting depth and the equivalent mud weight were simply determined for the area of study.
地层孔隙压力和裂缝压力梯度的预测是制定钻井计划的重要一步。本文以Waha石油公司NC98油田sirte盆地12口井为研究对象,根据实际钻井和测井资料,采用经验方法Eaton方程计算了地层压力。关于结果,正常NC98字段在苏尔特盆地孔隙压力是0.437 Psi /英国《金融时报》,并延长油井的顶部的调查面积7000英尺。一个低能的正常孔隙压力区发现在7000英尺至9000英尺的间隔。然后,略低于正常的有点异常(超压)地区从9000英尺到11200英尺之外,深度和储层的顶部,超压区显然是观察。在此基础上,简单确定了研究区域的套管下入深度和等效泥浆比重。

College of Geography and Environmental Science, Northwest Normal University, Lanzhou 730070, ChinaChief editors are the souls of journals, and can guarantee a journal’s success by enhancing the efficiency of the manuscript submission and publication process through promptness and speedy response rates to authors. In this study, a total of 867 international journals—indexed by Science Citation Index, Social Sciences Citation Index, and Arts & Humanities Citation Index, and 567 Chinese journals—indexed by Chinese Science Citation Database and Chinese Social Science Citation Information database, were randomly selected to explore whether significant differences in the response rate and speed exist between chief editors. 639 chief editor email addresses were obtained for the international journals, whereas 357 email addresses were gathered for the Chinese journals. However, due to mail servers, only 274 international and 330 Chinese editors were successfully contacted. All messages contained a questionnaire geared to determine the total length of time required for the manuscript submission and publication process. After two months, a 100% response rate was achieved for international chief editors, while Chinese chief editors had a significantly lower rate (p < 0.01) of 30.6%. Nevertheless, for both international and Chinese chief editors, 66% and 58% provided a response within 12 hours, respectively. Although several reasons exist for the Chinese journals’ lagging behind international journals, this study demonstrates that the response rate of chief editors to authors may also be a contributing factor. Thus, chief editors of Chinese journals should enhance their response rate to improve the current situation and further contribute to Chinese journals’ success.
主编是期刊的灵魂,通过及时、快速地回复作者,提高投稿和发表过程的效率,是期刊成功的保障。本研究随机选取《科学引文索引》、《社会科学引文索引》和《人文艺术引文索引》收录的867种国际期刊,以及《中国科学引文数据库》和《中国社会科学引文信息数据库》收录的567种中国期刊,探讨主编之间的回应率和速度是否存在显著差异。国际期刊共获得639个主编邮箱地址,国内期刊共获得357个主编邮箱地址。然而,由于邮件服务器的原因,只有274名国际编辑和330名中国编辑被成功联系上。所有信息都包含一份问卷,用于确定稿件提交和出版过程所需的总时间长度。两个月后,国际主编的回复率达到100%,而中国主编的回复率为30.6%,显著低于国际主编(p < 0.01)。然而,在国际和中国主编中,分别有66%和58%的人在12小时内给出了回复。虽然中国期刊落后于国际期刊有多种原因,但本研究表明,主编对作者的回应率可能也是一个影响因素。因此,中国期刊的主编应该提高自己的回应率,以改善现状,进一步为中国期刊的成功做出贡献。
