Published: August 2022

Abstract
The world is moving towards reuse, recycling, and low economic buildings in the AEC industry. Among these concepts, the reuse of shipping containers (SC) in architecture has seen a remarkable increase in recent times. Few studies have focused on the thermal performance of different stacking configurations using multiple SCs in hot climates to achieve the most suitable thermal performance and testing different passive design techniques. This study aims to know the most effective stacking configuration as a passive technique not tested before using SC as residential spaces in Cairo by analyzing its effect on their internal thermal performance. This paper presents a comparative analysis of four simulation models as separate residential units, including a control unit, an uninsulated SC, and three types of different configurations, three units horizontally connected, three units vertically connected, and the last model consists of three units connected both horizontally and vertically. The thermal performance of these units is tested as uninsulated SCs in the hottest and coldest days (23 August and 20 January, respectively) in the year using Design-Builder software. The paper concludes that the best configuration of SCs models that contribute to improving SC’s thermal performance in the hot climate is the vertical stacking configuration.

Abstract
This research aims to assess a compact economic housing model design proposal using walls constructed of compressed earth blocks as a nucleus for sustainable urban housing in Egypt. This research also aims to evaluate the effect of the direction of the proposed compact building on the building’s internal thermal comfort, energy consumption, and carbon dioxide emissions. According to previous studies, residential buildings represent about 50% of land uses in Egyptian cities, consume about 19% of the energy produced, and are responsible for 10% of carbon dioxide emissions. All previous environmental studies commended the thermal performance of courtyard buildings in the hot-arid climate of which Egypt is a part. As a result, the authors directed many previous studies towards new housing patterns in Egyptian cities using court-yarded clustered housing to improve thermal performance, decrease energy consumption, and reduce carbon dioxide emissions. This research compares two residential buildings using design-builder simulation. The two buildings have the same housing unit area of 90 m2 to represent the social housing unit area in Egyptian cities. The first comparative building is a conventional residential building surrounded by solar radiation from all sides and uses walls constructed of solid cement bricks (SCB). The second comparative building is a cluster open court-yarded building using walls built of Compressed Earth Blocks (CEB). Results show that both the clustered open courtyard housing model whose main axis is in the (N-S) direction and the use of CEB has improved all of the examined measures.

Abstract
Global climate change and global warming capture the attention of planners seeking more sustainable buildings to reduce dependence on fossil fuels and minimize energy consumption. Consequently, architects have developed buildings over the years and applied more sustainable strategies to cope with the environment, either in the shape of the building, the design of openings, or the use of more sustainable materials. These strategies provide more thermal comfort for long-term users. As a result, it is necessary to know the exact effect of using these strategies on thermal performance and energy consumption inside buildings. Therefore, researchers have developed many energy simulation tools and programs to provide a clear view of the nature of the building’s thermal performance and energy consumption based on data inputs about local weather situations of the building. Thus, we must know the ability of the software to model different design strategies and be sure that the results are valid. This paper aims to make an environmental simulation of an educational building in Montreal, Canada, using Design-Builder simulation and compare it with the as-built equivalent thermal zones applying different glazing materials, which is the main element of the building facade to enhance the thermal comfort with the lowest energy consumption and CO2 emissions. This paper shows that using double glass low E 6/6mm Air gap is better for the case study building in cold climate weather that increases thermal comfort for the users, reduces energy consumption by 18.63%, and also reduces CO2 emissions by 18.57% per year.

Published: August 2022

Abstract
The research was to explore the relationships between Construction Project manager skills and the performance of projects in Egypt. Specifically, this study investigated the relationship between the project manager skills (Technical Skills, Human skills, Conceptual Skills, Political and Social Skills) and the dimensions of project performance (Project Cost and Project Time). Hard skills include technological abilities, background, industry knowledge, and project experience. That define the tangible portion of a project manager’s resume as the 21st century recognition of project management. Data has been collected from 104 expert engineers who have a good realistic background in the field of construction industry; questionnaire survey is the used method. The results of analysis propose that risk management abilities have a significant association with project cost and time performance. The Egyptian construction sector may use the findings as a guideline to choosing project managers with the ‘suitable’ skills profile or focusing training and development programs on skills crucial for successful projects.

Abstract
The researcher proposes at this time an integrated framework for developing models of transition to sustainable ecological cities, and the goal is for cities to be able to adapt and be sustainable with different conditions. The contribution of this proposed model is to propose an effective scalable framework for sustainable urban transformation of communities that addresses the gaps and limitations of existing models. It takes into account the fundamental issues of urban societies including urban, environmental, social, economic and governance perspectives. The core of this framework consists of five dimensions that must be combined in order to achieve the objective of the proposed framework. It is the urban, environmental, social, economic and governance framework. Each of them has a number of main categories in addition to a number of criteria. The model contains an additional dimension, which is the dimension of information and communication technology that will be presented as an implicit dimension that will be included in all the five main dimensions, and these six frameworks have been collected in one equation in order to build the simulation model and then obtain the results of indicators and future expectation.

Published: August 2022

Abstract
Despite the remarkable evolution of the new Cairo cities and the development of the quality of life, some citizens of Old Cairo districts still lack the motivation to change their residence to the new cities. The landscape design in New Cairo cities mainly manifests large green areas with water features and contemporary building exterior design to create an ordered, calm, and comforting scene. However, the landscape design in Old Cairo districts creates a significantly opposite scene. In most Old Cairo regions, green areas of large old trees occupy tiny spaces, buildings’ exterior designs are bold and classic, and the whole scene manifests great chaos, crowd, and noise. Cairo is one of the ten least resilient cities around the world. The city is vulnerable because of its inadequate infrastructure, degrading environment, and vulnerable climate. According to the World Health Organization standards for green open spaces, Cairo’s green open spaces provide weekly liveability. This research demonstrates theoretical and practical techniques to understand the psychological effect of the different landscape designs on Cairo citizens.
Morphological changes of Cairo West power plant intake while using submerged vanes
Authors: Eizeldin Mohamed , Yasser Ahmed 
Published: August 2022

Abstract
Lateral intake structures suffer from sediment deposition and instability of flow path which may have a negative influence on the efficiency of power plants that use river intakes as a primary source for their cooling system. This study aims to experiment the usage of submerged vanes as a mitigation method and determine their effectiveness in decreasing sediment deposition. A numerical model was constructed using DELFT3D of a reach that is located in the Nile River including the intake structure. Several scenarios were tested to optimise several parameters such as the usage of one or two rows of vanes and the distance of the vanes from the lateral intake. The results generated from the model showed that using two rows of vanes provided a 30% reduction of erosion in front of the intake compared to the base case and a 33% reduction in the volume of sediment entering the intake. Moreover, a 36% reduction of sediment volume was observed compared to the base case when the vanes were placed at a distance that is equivalent to 0.3 the intake’s opening. The output of the model showed that it is more optimal to use two rows of submerged vanes at a distance that is equivalent to 0.3 the intake’s opening.

Abstract
To facilitate the water supply to the main cities in Malaysia such as Kuala Lumpur, Putrajaya and Cyberjaya, Pahang Selangor Raw Water Transfer Tunnel project is constructed in 2015. Facility tunnel of 44.6 km length with 5.2 m diameter are being constructed to transfer water from Karak to Hulu Langat. Granitic rock with dominant intrusive zones in various range of I until V were observed in the studied tunnel length. This tunnel has crossed sheared zone that categorized into fair, poor, and very poor rock classes with moderate to heavily jointed rock. At NATM-1, the discontinuities like joints that is close and far from the fault are one of the most important which caused to instability of the tunnel and reduced the performance of tunnel performance. In this paper, the joint orientation, overburden and distributions of discontinuities (joints and faults) into the tunnel were evaluated. These data were then simulated using discrete fracture networks with the direction of tunnelling excavation in the tunnel. Movement of blocks in the tunnel roof and wall is possible due to the creation of more intersection points in the critical zone. It also highlights how minor features, such as step-over joints in rock mass, can have a significant impact on instability.

Authors: Santoso Hendra , Gde Budi Indrawan I 
Published: August 2022

Abstract
Mining operations in areas with the potential for landslides require careful analysis of the risks that will occur so that the consequences of losses can be anticipated early with the approach to predicting the volume of landslide material. This study aims to evaluate and predict materials that are at risk of slope failures on the slopes of the PT. TMR mining located in Bengalon East Kutai District of East Kalimantan Province. The method used is to collect geological data, soil shear strength parameters and earthquake factors and the influence of groundwater on the body of the slope. Estimation of the predicted volume of slope failures based on the area of each slip surface is calculated using the prismoidal cross section method and multiplied by the probability of slope failures. The results show estimated volume of 122,298 m3 if the slope failure is caused by saturated slope conditions and 2,438 m3 if the slope failure is caused by a semi-saturated slope.
Morphometric Characteristic and Distribution of Hummocky Hills in Debris Avalanche Deposit of Galunggung Volcano, West Java, Indonesia
Authors: Alfin A S , Wibowo H E , Harijoko A 
Published: August 2022

Abstract
Sector collapse of a volcanic body produces topography of horseshoe-shaped caldera incisions and a widespread hummocky hill resembling debris avalanche deposit. The study of morphometry, distribution, and the alignment of the hummocky hills is necessary to understand the source and deposition process of the debris-avalanche deposit. Galunggung volcano is, one of the volcanoes in Java Island, attributed with 7 km wide of caldera opens towards the east direction (N 135° E) where hummocky hills cover an area of ~32 km2. Morphometry of the hummocky hills is 500-700,000 m2 in size, elongation ratio of 1.3-3.9. Hummocky hills are distributed 0.5 to 20 km distance from the summit of the Galunggung volcano. The elongation orientation of the hummocky hills is deviated from the main flow direction forming various angles. We divide the deviation angle into parallel (0-45°) and perpendicular orientation (45-90°). The maximum size of the hummocky hills generally decreases towards increasing distance from the summit. These hills also show changes in alignment from perpendicular to parallel, suggesting a typical free flow pattern of debris-avalanche deposits.
Reconnaissance study on the stratigraphy and characteristics of eruption products associated with basaltic caldera in Raung volcano, East Java, Indonesia
Authors: Moktikanana M L A , Harijoko A 
Published: August 2022

Abstract
As one of the most active volcanoes with significant eruptive impact in Indonesia, the Raung volcano shows a trace of the pre-historical devastating eruption as evidenced by the morphology of caldera at its summit. Our fieldwork revealed the occurrence of four pyroclastic fall deposits, two lava flows, ignimbrite, block and ash flow deposit, and lahar as the products of Raung eruption. There is evidence of Plinian phase eruption represented by layers of pumice fall without any significant time gap, which is uncommon for an andesitic-basaltic stratovolcano. Thin section observation on lava and the lithic fragment of block and ash flow deposits reveals that the composition of Raung volcanic products is mainly basalt consisting of plagioclase, clinopyroxene, olivine, and orthopyroxene as the primary crystal phases. Hornblende and biotite also compose pumice as a minor constituent. This evidence implies that Raung magmatism may potentially evolve long enough to produce such massive pumice fall deposits.

Published: August 2022

Abstract
The Sand-5 Reservoir in the Talang Akar Formation is the main oil and gas producer in the Field ‘S’, Asri Basin, Indonesia. Reservoir rock type (RRT) can be applied to optimize the performance of this reservoir. This study aims to compare the RRT methods between Hydraulic Flow Unit (HFU) and Windland R35 to find the best RRT method. Both methods utilized the porosity and permeability to classify the number of RRT, subsequently validated by the regression value (R2) of core permeability with predicted permeability. Four RRT values have been identified for both methods that are RRT-1 represent the very good reservoir quality, RRT-2 represents the good reservoir quality, RRT-3 represents the moderate reservoir quality and also RRT-4 represents the poor reservoir quality. The numbers of porosity and permeability for HFU method is 32-40% and 19.3-29.4 Darcy (RRT-1); 31-39% and 5.3-18.3 Darcy (RRT-2); 20-36% and 0.4-6.8 Darcy (RRT-3); 15-34% and 0.01-0.4 Darcy (RRT-4), while for Windland R35 method is 31-40% and 7.7-29.4 Darcy (RRT-1); 30-39% and 4-10 Darcy (RRT-2); 24-38% and 0.2-6.8 Darcy (RRT-3); 15-33% and 0.01-0.2 Darcy (RRT-4). Based on the relationship between core permeability and predicted permeability from each RRT, the result of the Winland R35 method is better than the HFU method.

Abstract
In this study, the diversity and structures assemblages of benthic communities present on artificial reefs (AR) immersed for 5 years were monitoring during a full year in 2020. The comparison of two different sites Bernières in the Bay of Seine and Cherbourg in the central part of the English Channel brings innovative results on the efficiency of such structures. Benthic fauna and macroalgae communities were studied; several biotic indices like Shannon-Wiener diversity index were calculated. Benthic fauna was classified according to their trophic group and the biomass was estimated. Our results pointed out strong differences for several indicators between sites and seasons. Benthic fauna was more abundant in the Bay of Seine and more diversified than in the Bay of Cherbourg. Primary producers’ diversity and biomass were higher in the Bay of Cherbourg and dominated by Rhodophyceae species. Primary production results showed that the Bay of Cherbourg was a more productive system than the Bay of Seine. This study highlighted the efficiency of such structures to create habitats and promote biomass and diversity of associated living communities. In comparable conditions, different systems were highlighted: a “primary producer reef” and a “primary consumer reef”.

Abstract
A main cause of biodiversity loss is artificialization of the marine environment (IPBES 2019). With 39,400 km2 of coastal and marine areas already encroached upon by human infrastructure and an increasing demand on space due to the growing global population – projected to reach 9 billion by 2050 – it is clear that humanity needs to find ways to prevent its activities from endangering biodiversity. To this end, since the 1990s ecologists have been trying to develop a win-win approach that unites ecological engineering with civil engineering. Today, civil engineers have a responsibility to incorporate eco-design processes in all construction projects underway to ensure that the latter benefit both humans and nature. Then, the new challenge of the 21st century is to develop eco-designed concretes that, in addition to their usual properties, provide improved bioreceptivity in order to enhance marine biodiversity without affecting the structure durability. The aim of this study is to master, clarify and classify the intrinsic parameters that influence the bioreceptivity (biocolonization) of cementitious materials in the marine environment. By using biofilm-culture-method (biofilm quantification), this study shows that the use of rough surface or slag cement CEM III and the surface treatment with green formwork oil enhance the biocolonization of cementitious materials in the marine environment whereas the application of curing agent (hydrophobic surface coating) has the opposite effect. Among the influent parameters, surface roughness proved to be the factor that promotes biocolonization most effectively.

Abstract
Conventional in vitro cancer models do not accurately reproduce the tumor microenvironment (TME), so three-dimensional (3D)-bioprinting represents an excellent tool to overcome their limitations. Here, two multicellular tri-layered malignant melanoma (MM) models composed by cancer stem cells (CSCs) isolated from a MM established cell line or a primary-patient derived cell line, fibroblasts, mesenchymal stem cells, and endothelial cells, embedded within an agarose-collagen type I hydrogel were bioprinted. Embedded-cells showed high proliferation and metabolic activity, and actively remodeled their TME. MM hydrogels displayed similar rheological properties that skin and were able to support an early onset of vascularization. Besides, MM hydrogels displayed different response to vemurafenib compared with cell cultures, and supported tumorigenesis in murine xenotransplant achieving more mimetic in vivo models. For the first time a tri-layered 3D-bioprinted CSC-based human MM model is developed recreating TME in vitro and in vivo and response to treatment, being useful for precision treatment regimens against MM.
