Abstract
Coastal ecosystems have the potential to contribute to disaster risk reduction and adaptation to climate change. While previous studies have estimated the value of current coastal ecosystems for reducing coastal risk, there have been relatively few studies that look at changes in ecosystem service provision, in the past and under climate change. We employ the probabilistic, event-based CLImate ADAptation platform (CLIMADA) to quantify the protection from tropical cyclones (TCs) provided by coastal ecosystems, modeling the number of beneficiaries in the past and under future climate change. We also investigate the potential of nature-based solutions (NbS), such as mangrove restoration. We find that currently, one in five (21%) of all people impacted annually by TCs in the global low-elevation coastal zone is within the protection distance of coastal ecosystems. Over the last 30 years, the share of protected people has decreased by approximately 2%, due to ecosystem loss. With climate change, the average annual number of people impacted will increase by 40%. Simultaneously, the proportion of people protected by coastal ecosystems with climate change decreases due to changes in TC distribution (−1%). The importance of current coastal protection, and the potential for increasing protection by NbS, varies widely between countries. While the number of people protected globally only increases slightly with mangrove restoration, the share of people protected in individual countries can increase by up to 39%. Our findings provide a basis for NbS planning and adaptation policy, by highlighting areas which will be crucial for coastal protection services in a world altered by climate change.

Abstract
For thousands of years, engineers have been grappling with slope instability as an issue in geotechnical and geological engineering. Earthquake loading has a great impact in slope stability. The present study is to investigate the impact of various soil properties and slope geometry on FOS in the presence as well as in the absence of seismic loading. Here, pseudo-static methods are used to analyses seismic slope stability under earthquake loading. From parametric studies, present work concluded that the FOS values start to decline drastically with earthquake impact. Moreover, various prediction models have been developed using Multiple Linear Regression (MLR) & Multiple Non-Linear Regression (MNLR) considering all the data. The input data of slope stability estimation consists of the values of soil parameter, slope parameter and earthquake loading parameters. As an output, MLR and MNLR predict FOS values as a function of these parameters. The model is then checked by comparing the results to another ten actual situations. It was found that the predicted FOS using MNLR gives satisfactory results.

Abstract
Start with the Scarcity of materials in concrete so sand has steadily gained prominence as the most frequent building material used in the construction industry. As the population increases, so does the need for residential and commercial space. The most essential resource for mankind, river sand, is being mined out of riverbeds more frequently. One ton of regular Portland (OPC) cement is produced in India for every tonne of CO2 that is released into the environment. By substituting cementitious materials like fly ash and ground-granulated blast furnace slag for ordinary cement, we can lower the number of greenhouse gases that are emitted into the atmosphere. To create sustainable concrete pavement blocks, this experimental work has been carried out with the use of cementitious elements including fly ash and ground granulated furnace slag (GGBS) as a replacement for cement, and to enhance public transportation, this research is focused on creating paver blocks that contain sea sand as fine aggregate. This experimental investigation was conducted to investigate different sustainable concrete strength properties with 0% sea sand, 50% Sea Sand and 50% M sand, and 100% sea sane used to partially replace the mix proportion. Results of mechanical parameters such as Compressive strength, water absorption, abrasion resistance, and carbonation of these sustainable concrete pavement blocks are presented also a cost analysis of paving blocks was evaluated.

Abstract
For a better sustainable progressive world, construction industry turned wider gradually. It is well known fact that cement concrete is main component of construction for our modern civilization. Now days, fly ash is used as the most potential replacement material in cement concrete, as production of cement very badly harm our environment. Reports show that one tonne cement produces one tonne carbon dioxide in our environment and responsible for global warming. After successive research work, it is proven that replacement of high volume fly ash (above 50%) which is pozzolanic in material (consists of siliceous and aluminous compounds) in cement paste helps to achieve high strength, porosity, heat of hydration, micro structure as well as very economical and eco-friendly against normal cement paste. This paper mainly highlights on the detailed study of rheological and strength properties of high volume fly ash concrete (50%-70% replacement of cement in various grades of fly ash mixed as per IS standards) in addition with various additives and melamine based admixture. In addition to this, other properties such as consistency, hardening and stiffening, workability, mechanical properties are studied. This overall study include experimental program on various concrete specimen with varied cementitious content along with admixtures.

Abstract
Safety of water tanks is very important as they are very important life living structures. Tanks shall always be functional for the access to drinking purpose as well as for the requirement of fire fighting in the area of occurrence of earthquake. The study focus on analysis of RC water tank of circular shape in accordance with IS 1893 (Part-2):2014. The analysis of tank is carried out for zones II, III, IV and V and Rocky or Hard Soil, Medium Stiff Soil and Soft Soil conditions in accordance to Indian standard. Further three different depth of water with constant diameter ratios with tank full, half-filled and tank empty condition are considered for analysis. From the analysis, it is found that tank design is governed in full tank condition. Values of seismic horizontal design coefficient in impulsive mode (Ahi) are less than those for convective mode (Ahc), for full tank condition. This is due to lower values of time period in impulsive mode. For the same soil condition, values of Ahi and Ahc increases for higher seismic zone. The values of highest shear and moment at bottom of container are found to be governing in full tank condition as compared with half-filled and empty tank condition.

Published: November 2023

Abstract
Structures made of reinforced concrete are susceptible to developing cracks when they are in the path of earthquakes, strong winds, or increased structural loading. It is therefore possible that it will be necessary to manage structural cracking in the Service Limit State to maximise the lifetime and strength of the structural components under any stress. Helical containment is superior to rectangular containment in terms of its ability to strengthen and ductile the Reinforced Concrete (RC) structural member. In the current work, six distinct beams were each subjected to a series of tests to see how they behaved in terms of cracking when subjected to bending loads. Each of these tests used a unique helical pitch space distance. The beams all measured 150 mm by 150 mm and 750 mm in length. They were designed in accordance with the criteria of Euro code 2, with the identical dimensions. Both 50 and 100 mm were used to take the measurement for the helical pitch. The findings indicate that the utilisation of helical elements does influence the cracking behaviour of the beams. The most important finding was that the measurement of the crack’s thickness was slightly reduced when the beams were restricted to a helical zone with a closer spacing between them. The fact that the theoretical crack is longer than the actual crack that was measured experimentally demonstrates that the Euro code 2 standard provides a more accurate forecast as well as a higher factor of safety. This is demonstrated by the fact that the theoretical crack is larger than the actual crack that was measured.

Abstract
In India’s main cities, high-rise reinforced concrete residential buildings with more than 15, 16, or 17 stories are widespread these days, which are aligned parallel to the Indian government’s “Pradhan Mantri Awas Yojna”. The development of an economical and eco-friendly R-C building by providing a limited area of shear walls at the diagonal corners of the structure is evaluated in STAAD-PRO and ETAB in this paper. This work also focuses on the location and minimal area of shear walls along with maximum strength, and its 3-D analysis gives conclusions. The paper concludes that the design of 20-story buildings in STAAD and ETAB with minimum shear walls gives safe results, and Horizontal forces increase the structure’s strength and stiffness requirements.

Abstract
The objective of this study is to delineate and identify the groundwater potential zone of degraded land in the Echway watershed, southwest Ethiopia, employing a combined approach that includes 2D electrical resistivity, the analytical hierarchy process (AHP), geographic information systems (GIS) and remote sensing (RS). Using a geographic information system (GIS) and remote sensing data, groundwater potential zones were identified by taking into account the soil types, drainage density, geology, lineament density, Land use and land cover, rainfall and slope. Using the AHP method, calculate the weight of thematic layers and rank of subclasses based on the effects of various thematic layers on groundwater potential. A significant weight was provided on the geology of the research region, total annual rainfall, and lineament density. Due to significant effects on groundwater potential zones, only three of the seven theme levels were assigned significant weight in this analysis. The weighted overlay analysis was used to construct the diagram of the zones with groundwater potential. 2D electrical resistivity was utilized to find the groundwater aquifer, and four major electrical layers were discovered: clayey silt, sand, moderately weathered/fractured rock, and basement parent rock. The groundwater potential zones in the study area have been classified into five categories: very low (22.97%), low (13.43%), moderate (32.50%), high (25.12%), and very high (5.98%) covered, respectively. The groundwater potential zone image was created by combining GIS, remote sensing, AHP, and an electrical survey

Abstract
Despite having several negative effects on human life and the environment, cement is the main component of concrete. Carbon dioxide is released into the atmosphere as a byproduct of cement production. As a result, cement production must be curtailed to lessen environmental impact. Therefore, it was crucial to find a material that could replace cement but wouldn’t harm people or the environment in the process. When compared to cement, burnt clay (or sarooj) is seen as more eco-friendly because of its similar properties and uses. It was investigated in this study whether sarooj could be used to replace cement in concrete at different percentages (0%, 10%, 20%, 30%, and 40%). Several tests, including a sarooj chemical test, a slump test, a water absorption test, a rebound hammer test, a compressive strength test, and a flexural strength test, were performed on the concrete to ascertain its mechanical qualities. Based on the results, 10% sarooj is the best option because it outperforms 20%, 30%, and 40% in compressive and flexural strength, respectively.

Published: November 2023

Abstract
The present study will describe the characteristics and the effects of concrete properties when fine aggregate is partially substituted by steel slag and cement partially substituted by metakaolin and glass powder at 0%, 10%, 20% and 30. Compressive, tensile, flexural strength, and durability tests were conducted on the cube and cylinder specimens. The test results were compared with conventional concrete specimens. The tests are conducted on specimens for 7days and 28days. Based on the outcomes of the study, it was concluded that replacing cement and fine aggregate with glass powder, metakaolin, and steel slag increases the strength of concrete and reduces attack at 30% replacement. Hopefully, the results have clearly demonstrated the concrete constructions can also be made from eco-friendly alternative materials which are cost-effective and sustainable for longtime.

Published: November 2023

Abstract
Planning, designing, and execution of high-raise building while taking into account the impact of lateral loads such as wind and seismic loads computation with or without shear wall technology in conventional mode is a crucial task for civil engineers. The lateral loads develop high lateral stresses and sway movement in structural members and need adequate stiffness to resist lateral forces along with sufficient strength against vertical gravity loads. In this case, civil engineers establish an effective system for construction of high raise building with the usage of shear wall system is high in-plane stiffness and torsional resistance. Present the authors are considered a G+10 storey commercial shopping mall with a central cut-out at Bhimavaram location which lies in seismic zone III as, per IS 1893(part 1): 2016. The load cases from IS 875 Part I (dead loads), Part II (imposed loads), and Part III (wind loads) are used to create the load combinations in accordance with IS 456: 2000. Two models, with and without shear wall system are taken for comparing the parameters like storey drift, storey displacement, stiffness, shear force, base shear, bending moment and center of rigidity by performing linear static seismic analysis and wind analysis for both models in ETABS software. The simulations concluded that Shear wall system is the efficient and economical way of resisting lateral loads in high rise or multistory buildings.
Study of the Effect of Installation of Stone Columns on the Stability of Soil Slopes using Finite Element Method
Authors: Goswami A , Deka S 
Published: November 2023

Abstract
There are several ways to mitigate the failure of a soil slope. The installation of stone columns for this purpose, is easy as well as economical. As their strength is greater than that of soil, they disrupt the slip surfaces. Also being more porous, they dissipate the pore pressure generated in the soil in the vicinity of the stone columns to a certain extent. This paper illustrates 2D finite element analyses carried out to simulate the behavior of stone columns in cohesive soil using the computer program PLAXIS. Parametric study was conducted to analyze the effect of number, length and diameter of the stone columns on the Factor of Safety of the soil slope. The F.O.S. of the soil slope was predicted using prediction models created using artificial neural networks (ANN) considering slope geometry like slope angle and height, material properties like cohesion and angle and internal friction of soil as well as granular material used in the columns, and the stone column parameters like the stone column’s number, length, diameter and the centre to centre (c/c) distance between two adjacent columns as input parameters. It was found that introduction of stone columns significantly improved the stability of the soil slopes. Further, it was seen that all the parameters considered in the study influenced the Factor of Safety of the soil slope.

Published: November 2023

Abstract
This study proposes a facile method for superhydrophobic and slippery-infused porous surfaces for water repellency and anti-icing purposes. Both adhesion force and time delaying were systematically investigated, showing their strong dependence on surface parameters and slipperiness. The uniform patterns of nanoscale textures inspired by rose leaf structure have been generated on silicon wafers using the plasma etching process. We believe the lower real contact area can play a dual role in the icing mechanism including reducing heat transfer and adhesion force attributed to the projected area. On the other hand, slipperiness plays an important role in reducing adhesion strength and preventing ice nucleation. The slippery superhydrophobic surface demonstrates outstanding in reducing the adhesion strength while documenting several times lower compared to bare Si, superhydrophobic Si, and slippery Si surfaces. In addition, the rational combination facilitates the efficient function after a number of test cycles, illustrating the mechanical anti-corrosion properties. The results lead to understanding the role of the icing process and designing the anti-icing structure.

Published: November 2023

Abstract
Aqueous ZnS quantum dots (QDs) were synthesised via a facile, cost-effective one-pot synthesis method in the ambient environment. To achieve most favourable ratios of thioglycolic acid (TGA):zinc (Zn):sulphide (S), the concentration optimisation by optical spectra (COOS) method was adopted. The x-ray diffraction (XRD) spectra confirmed the zinc-blende (cubic) phase of ZnS quantum dots (QDs), and Scherrer’s method determined that on average, the QDs exhibit a size of 2 nm. The Fourier-transform infrared spectroscopy (FTIR) study shows that characteristic peaks are consistent with the vibrational modes of the TGA ligands, confirming the capping. The quantum dots (QDs) synthesised displayed a significant effect of quantum confinement with blue shift in absorption peaks, compared with bulk ZnS absorption peak. Interestingly, on increasing the concentration of TGA, it resulted in red shift at the absorption edge, shifting from 300 nm to 314 nm. On the other hand, increasing the concentration of cation Zn and anion S ratio led to a blue shift, ranging from 315 to 295 nm, and a red shift, ranging from 280–320 nm, at absorption edges respectively. A prominent emission peak appeared at 428 nm. The application of Brus equation allowed estimating the size of the quantum dots (QDs) to be within the range of 2 to 2.7 nm, which correlated well with the Bohr’s radius of ZnS. This favourable property proposes the use of QDs in various optoelectronic devices.

Published: November 2023

Abstract
The photoluminescence (PL) properties of nitrogen-doped graphene quantum dots (NGQDs) are highly dependent on reaction parameters. In this study, we developed new and fast protocols to surface passivate NGQDs with polyethylene glycol (PEG) using microwave irradiation. The resulting NGQDs-PEG exhibited highly stable PL with an emission peak at 424 nm when excited at 325 nm. The PL intensity of NGQDs with PEG increased with the volume of capping agents due to the enhancing luminescence effect of the surface functional group of polyethylene glycol. The optimal PEG amount of 2 wt% was found to improve the PL effect of NGQDs. Interestingly, the surface passivation of NGQDs with PEG enabled the NGQDs to exhibit strong PL performance across varying pH environments (from acidic to alkaline), addressing the issue of quenching of quantum dots in biological environments. Our research also focused on the ultrafast synthesis of NGQDs, where process parameters such as power value, catalyst volume, and reaction time were identified as important factors affecting NGQD luminescence. Our results showed that the optimal microwave power was 640 W, lower than that used in previous synthesis methods. Increasing the volume of catalyst promoted faster NGQD formation. The optimal reaction time was found to be 5 min, catalyst volume of 5 ml resulted in the highest PL intensity of NGQDs.
