In recent years, most cities have faced great demand for electricity supply due to rapid population growth and industrialization. Supplying sufficient electrical energy, while reducing greenhouse gas emissions, is one of the major concerns policymakers scientists all over world. Saudi Arabia, local authorities are increasingly aware necessity environmental impact nonrenewable energy by exploring alternative sustainable sources improving buildings’ efficiency. Recently, building-integrated...
The problem of metal-induced toxicity is proliferating with an increase in industrialization and urbanization. buildup metals results severe environmental deterioration harmful impacts on plant growth. In this study, we investigated the potential two ornamental plants, Catharanthus roseus (L.) G.Don Celosia argentea L., to tolerate accumulate Ni, Cr, Cd, Pb, Cu. These plants were grown Hoagland’s nutrient solution containing metal loads (50 µM 100 µM) alone combination a synthetic chelator,...
The natural quality of groundwater tends to be degraded by industry, agriculture, and wastewater. There are several alternatives prevent migration the spread pollution in groundwater. Some physical such as grouting, or slurry walls. Others could hydrodynamic containment injection pumping wells. Injection wells used confine a pollutant place dilute its concentration injecting clean water into aquifer. Pumping discharge pollutants out reservoir act interceptors. In this research, hydraulic...
Abstract The current study examines the physical properties of Co 2 ZrZ compounds (Z= Pb, Bi and As) using Wien2k calculation code. Anisimov Gunnarsson approach is used to calculate Hubbard parameters for Cobalt (Co) Zirconium (Zr). results indicate that ZrBi ZrAs have metallic characteristic, however ZrPb displays semi-metallic behaviour. energy gap calculations provide values 0.328 eV (GGA) 1.102 (mBJ-GGA) in G-X-direction. valence bands are primarily influenced by Co-D-eg Co-D-t g states...
Phenolic compounds are toxic and ominously present in industrial effluents, which can end up water bodies, causing potential damage to living organisms. This study employed the dried biomass of freshwater green microalgae Chlorella vulgaris remove phenol 2-chlorophenol from an aqueous environment. C. was grown under different phosphorus- (P) starved conditions, treated with sulfuric acid. It observed that reducing P level enhanced lipid content by 7.8 times while decreasing protein 7.2...
The main objectif of this work is to examine the thermal environment's effect on free vibration double curvature shells made functionally graded materials. A new mathematical model based higher order shear deformation theory, developed incorporate influence dependent and independent stresses, which can be uniform, linear, nonlinear, or sinusoidal mechanical properties shell. Two material couples, (Si3N4/SUS304,ZrO2/Ti‐6Al‐4V), are considered as progressive materials, accounting for...
This study introduces a novel theory employing four unknowns to examine bending of double-curvature functionally graded shells experiencing both uniform and sinusoidal pressure. investigation utilizes 2D quasi-3D higher order shear deformation theories, integrating fresh model high-order displacement field. It focuses on exploring how geometric ratios, volume fraction power law index influence the behavior, specifically examining their effects normal stresses variation, along with...
The paper describes a theoretical and experimental study of the flexural torsional properties braced, thin‐walled, open sections, such as elevator core shear walls with lintel beams across openings at each floor level. model developed is based on an equivalent closed section, it consistent established open‐section closed‐section behavior two extremes bracing. For intermediate bracing, incorporates influences bending deformation continuous flow around out‐of‐plane side walls, which analyzed...
This paper presents the flexural analysis of functionally graded plates resting on elastic foundations using new two-dimensional (2D) and quasi-three-dimensional (quasi-3D) higher order shear deformation theories. The main interesting feature this theory is that it proposes a displacement field with undetermined integral variables which involves only five unknown functions, unlike other normal theories, hence making easier to use. A parabolic transverse shape function satisfying zero stress...
Structural instability becomes an important concern in the composite plate safe and reliable design. In this research, a resistance analysis is carried out on plates made of hybrid material with without elliptical cutouts using finite element method. The carbon/epoxy/aluminum laminated are arranged following ordered manner [Al/(θ/-θ)/Al]. to buckling submitted uniaxial compression highlighted. Results indicate that given structural geometry, boundary loading condition stacking sequence, such...
The repairing process of structures using bonding composite materials is an efficient and economic way increasing service life damaged structures. finite element method developed applied to assist in the design, assessment optimization proposed plans before they are implemented, therefore reducing cost time.

The significance of groundwater is largely shaped by the quality wastewater from industrial, agricultural, and municipal sources. Understanding controlling factors essential to prevent spread contamination in groundwater. These could be divided into physical defenses, such as grouting slurry walls, hydrodynamic factors, injection pumping wells. In this study, transport model (MT3D) flow (MODFLOW) were used simulate four scenarios for protection. first second involve constructing walls change...
