Authors: Hala Hussam Eddin Malandi Hala Hussam Eddin Malandi
Published: April 2022

Squares are the soul of the city; because they play an effective role in the structure, life and identity of cities and the promotion of the urban environment in them, and are characterized by being enjoyable and can be accessed by everyone for free at any time. Each public square has its own spatial, historical, environmental, social and economic characteristics. Therefore, the identity and characteristics of the public urban squares must be developed and improved to match the place in which they are and with the change in the behavior of its users over time. The problem of the research is manifested in the lack of Al-Alamji Square in the old city of Aleppo to the spirit of the place within it, which is the traditional historical fabric in terms of its surrounding facades and in terms of its urban design, which affected its social, economic and cultural role. Therefore, the research aims at evaluating the Al-Alamji Square according to characteristics deduced from a theoretical documentary study of the bases for evaluating public squares internationally approved in this field and the stages of development of the squares historically, analyzing them and intersecting them together to conclude the most important factors that hinder public squares from performing their role, and on the other hand, the factors that support the squares to be socially, economically and culturally attractive. The research also reviews the experience of rehabilitating a new square in a historical area in Melbourne, taking advantage of the steps to address its design problems that affected its effectiveness, and then moves to the case study by evaluating it according to the theoretical and the deductive study. Suggestions, through illustrative sketches, to re-design Al-Alamji Square to accommodate different activities and modify its facades so as to harmonize with the traditional fabric of the area, increase the proportion of green spaces, determine the entrances to the square, and other suggestions, in order to improve its role as one of the important public spaces created in the old city of Aleppo.

The feasibility of using glass facades for buildings in the State of Kuwait
Authors: Tariq Ibrahim Muhammad Al-Nukhailan Tariq Ibrahim Muhammad Al-Nukhailan
Published: April 2022

Recently, some press articles and opinions have come out that talk about aesthetic problems of glass facades. These problems are summed up in the excessive glare of these facades, raising the temperature in the external areas, and the effect of these facades by dust and storms that pass through the State of Kuwait, leaving a bad impact on them that loses their aesthetic value. I favored this research paper. To determine the extent to which these facades are suitable for the Kuwaiti climate, as there are towers with high-rise glass facades that occupy international ranks in terms of the elegance of the design and the aesthetics of the building. In the research, I wondered whether the process of transferring the use of these facades to our country was carried out without studying the climatic conditions of these countries. Or are there design errors in transportation, or is it a change in the climate, or are these facades suitable for the hot climate with some modifications to suit the climate? And I noticed through the research that most of the research tended to study the modern uses of facade glass in terms of providing comfort to the user and reducing energy. Through its content, the research dealt with a case study of some existing models of towers with glass facades in Kuwait, and conducting analyzes of them and studying the research related to them.

Authors: Zuhair Amer Zuhair Amer
Published: April 2022

Construction and restoration operations have developed rapidly since the beginning of this century. This development coincided with the trend of towards developing and discovering new building materials that meet the aspirations and needs of those interested across all engineering fields. One of the most important building materials currently being developed is carbon concrete, in which carbon is used for reinforcement instead of steel, which has been the material in use until today. Due to the many advantages of using carbon concrete whether in building new structures or in repairing, strengthening and consolidation of existing buildings, this innovative material will replace conventional reinforced concrete in the near future. This study aims to shed light on carbon concrete and present the latest findings of scientific research on this material and its production and use techniques, whether in modern buildings under construction or in existing buildings for the purpose of repair and rehabilitation. It also aims in its experimental part to study the effects of reinforcement using carbon concrete on the behavior of implemented concrete elements (for example, column elements) by changing many parameters. This research paper presents the characteristics and components of carbon concrete, its manufacturing methods and areas of use, in addition to the advantages and disadvantages of the new carbon concrete through a brief overview in order to introduce this creative building material in the Arab sector and encourage its use as an alternative to reinforced concrete. However, there is still an urgent need for scientific research into the details of carbon concrete. Only then can standardized and complete concepts be presented for their practical use and, above all, the code version to be followed when utilizing them.

Acetate Cellulose (CA) is a natural polymer from cellulose used mainly in the manufacture of filters, films, and plastics. Natural polymers have been mainly used in industrial and biological fields due to their safety and low production costs, and biodegradability. The study focuses on preparing acetate polymer from spinning waste by different methods with acetic acid 80% at acetylation time (15- 30) minutes and 70% acetic acid at a acetylation  time (120- 180) minutes. (Experimental values were obtained based on the speed of forming a network of cellulose acetate fibers prepared on the electrospinning apparatus). The prepared (CA) was tested with a nuclear magnetic resonance (NMR) test, the thermal behavior was determined by the DSC test. The research shows that high (DS) was obtained at concentration 70% and high acetylation time, while the (DS) was lower at 80% concentration and low acetylation time. From the DSC test, we find that both the glass transition and melting temperature decrease with increasing the (DS), while the crystallinity increases with decreasing the (DS).

Published: April 2022

People are hearing various natural and artificial sounds, but it is hard to imagine how hearing the sounds from people collectively can be effectively used in our everyday lives if those sounds become sharable. The sharing economy, which uses digital technologies to share a variety of physical resources in a peer-to-peer manner, has been attracting attention in recent years. Investigating the feasibility of sharing human hearing offers promising opportunities with which to expand the current scope of the sharing economy. In this study, we have developed a digital platform named CollectiveEars to share collective human hearing and explore the opportunities and pitfalls of sharing human physical senses on a digital platform. The first contribution of the study is to present an overview of CollectiveEars. The second contribution is that we reveal opportunities and pitfalls of CollectiveEars by extracting insights from two experiments. The third contribution is to show three examples to extend CollectiveEars.

Published: April 2022

The share of e-commerce has been rising uninterrupted for many years, but the largest share of sales is still achieved in stationary retail. Nevertheless, many retailers are forced to address the benefits that consumers have gotten used to through digital shopping experiences. Smart Retailing (SR) is seen as a possible solution for brick-and-mortar stores to answer the challenges created by the rise of e-commerce. This study aims to present the current state of research in SR and evaluate its potential to confront the challenges that have arisen in the industry. To do so, we built upon insights from previous works, in which we derived specific areas of impact that need to be considered when implementing those technologies. In this work, we substantiate our developed assessment with empirical data generated through the analysis of exploratory expert interviews. The \textit{gain of valuable data} and the \textit{personalization of the shopping experience} are confirmed among the positive impact factors. At the same time, \textit{privacy concerns} and \textit{customer acceptance risk} were the most discussed negative impact factors in the interviews. Finally, the interview findings were used to adapt the Technology Acceptance Model (TAM) to the specific context of SR. Overall, this work provides more profound insight into the essential factors that need to be considered by brick-and-mortar retailers to face the increasing pressure imposed by online competition.
Bayesian Sequential Stacking Algorithm for Concurrently Designing Molecules and Synthetic Reaction Networks
Authors: Zhang Qi , Liu Chang , Wu Stephen , Yoshida Ryo
Published: April 2022

In the last few years, de novo molecular design using machine learning has made great technical progress but its practical deployment has not been as successful. This is mostly owing to the cost and technical difficulty of synthesizing such computationally designed molecules. To overcome such barriers, various methods for synthetic route design using deep neural networks have been studied intensively in recent years. However, little progress has been made in designing molecules and their synthetic routes simultaneously. Here, we formulate the problem of simultaneously designing molecules with the desired set of properties and their synthetic routes within the framework of Bayesian inference. The design variables consist of a set of reactants in a reaction network and its network topology. The design space is extremely large because it consists of all combinations of purchasable reactants, often in the order of millions or more. In addition, the designed reaction networks can adopt any topology beyond simple multistep linear reaction routes. To solve this hard combinatorial problem, we present a powerful sequential Monte Carlo algorithm that recursively designs a synthetic reaction network by sequentially building up single-step reactions. In a case study of designing drug-like molecules based on commercially available compounds, compared with heuristic combinatorial search methods, the proposed method shows overwhelming performance in terms of computational efficiency and coverage and novelty with respect to existing compounds.

Published: April 2022

We demonstrate that the strong N2 bond can be efficiently dissociated at low pressure and ambient temperature on a Si(111)-7x7 surface. The reaction was experimentally investigated by scanning tunnelling microscopy and X-ray photoemission spectroscopy. Experimental and density functional theory results suggest that relatively low thermal energy collision of N2 with the surface can facilitate electron transfer from the Si(111)-7x7 surface to the p*-antibonding orbitals of N2 that significantly weaken the N2 bond. This facile N2 triple bond dissociation on the surface leads to the formation of a Si3N interface.

This is because rGO has a heterogeneous structure consisting of a basic plane such as graphene which has a structural defect due to the insertion of oxide into its structure. rGO material is widely used because the synthesis method is easier when compared to graphene synthesis, but rGO has a structure and properties that resemble compared to graphene. Synthesis methods for producing rGO are micromechanical peels from graphite crystals, epithaxial growth, chemical vapor deposition (CVD) and chemical synthesis by oxidizing graphite. From the results of the synthesis of rGO has superior properties namely good electrical conductivity, large surface area, good chemical stability, and high power density. However, there are problems in rGO before being modified with other materials, which have low dispersibility in ordinary organic and inorganic solvents. Therefore this article discusses the latest development of the structure, properties and performance of rGO and its composites based on a review of various articles, so that it can expand its applications such as batteries, supercapacitors, catalysts, optoelectronics, anti-corrosion materials, and membranes.Keywords: reduced graphene oxide, graphene, composite
