Abstract PFAS (per- and poly-fluoroalkyl substances) is a complex family of manmade highly fluorinated aliphatic organic chemicals including thousands of chemical structures identified. A research was carried out at a municipal wastewater treatment plant (MWWTP) in Northern Italy to define the inflowing load of PFAS, the main load sources and the removal efficiency of the treatment processes. Then, the 100 industrial settlements served by the MWWTP were examined, and 8 of them were selected as potential PFAS sources. The calculated loads summed up to 98.5 % of the total load entering the plant

Abstract:
Ensuring the stability of slopes is always a challenging problem for geotechnical engineers. Be the slope manmade or natural, unless it is safe under every load condition, it can inflict damage to human life and livelihood. The two basic approaches in slope stability analysis are limit equilibrium method and finite element method. This paper aims to review the effect of various magnitude earthquakes on stability of slopes of different height, slope angle and shear strength parameters using the finite element software PLAXIS. Stability of a slope is best assessed in terms of its factor of safet

These pipelines incorporate several structural and protective layers to resist different loads, and may require additional protection such as trenching, rock placement, or burial. In practice, simplifications are considered due to the complexities and uncertainties involved in the multi-layer pipe structure and the surrounding soil, compromising the pipe structure or the soil behavior. These simplifications are applied either on the pipe by assuming a rigid section o

Material science advancements have resulted in the development of high-strength concrete and steel reinforcement, allowing more efficient and stable buildings against natural and manmade disasters. Increasing security concerns and the potential threat from terrorist activities have led to the safety and resilience of structures against blast loads in modern construction. The present study investigates the performance of reinforced concrete shear walls in mitigating blast-induced vibrations.

Glacial deposits are of significant importance to geotechnical engineers and geologists in northern Europe, North America, and Northern Asia, as vast areas of these land surfaces were historically covered with ice leading to the formation of a wide variety of till deposits. The use of these areas for various engineering purposes warrants their subjection to mechanical loads (of static and cyclic forms) from manmade structures, as well as natural hazards such as earthquakes. This paper focuses on the experimental investigation of the cyclic mechanical loading behavior of two glacial tills from

Abstract Earthquake is one of the major natural disasters in the world. It considered that. The damage caused due to the collapse of buildings during the earthquake is huge. The main reason for this calamity is the extirpation of manmade structures. The structure’s lack of lateral rigidity is the first reason for its destruction during an earthquake. multi-story buildings need a seismic motion for their stability. Some endeavors have been done for finding the best method to make multi-story buildings strong and stable against earthquake forces. Provision of shear wall is one of the main option

Abstract Auxetic materials belong to a class of well-organized manmade materials that possess negative Poisson’s ratio when applied load. Typically, they consist of periodic unit cells that show low Young’s and bulk moduli due to their unique structure. Thus, most of the classical auxetic materials exhibit soft behavior. Recently, some of the works investigated auxetic materials with stiff mechanical behavior. In this paper, we review auxetic structures and design methods to design soft or stiff auxetic materials, as well as their potential applications. Generally, auxetic materials fabricated

Strain locking materials have a limit to the extent to which they can be stretched along one or more axes. The strain limit can be due to the reorientation of stiffening phases at microstructural or molecular scales along the direction of the applied load. Both natural and manmade composites can exhibit such a response when initially wavy fibers or other corrugated structures gradually straighten and limit the extensibility of the material. A new constitutive model is developed for materials that exhibit strain locking along a preferred axis. The model assumes the microstructure is composed of
