DISTRIBUTION, ECOLOGICAL AND HEALTH RISK ASSESSMENT OF ANIONIC SURFACTANT (LAS) AS A MOLECULAR MARKER FOR WASTEWATER DISCHARGE IN EKBATAN DAM, HAMEDAN

Background and Aim: Given the increasing use of detergents and the problems of water pollution caused by the release of wastewater containing large amounts of detergents in recent decades, this study aimed to investigate the concentration and health and ecological risk assessment of linear alkylbenzene sulfonate (LAS) as the most important detergen

Body Wash In this work, TiO2 photocatalysts were synthesized using a conventional sol-gel and hydrothermal synthesis methods with steam pressure treatment.Photocatalysts were characterized by X-ray diffraction (XRD), diffuse reflectance spectra (DRS) and N2 adsorption-desorption.The photoactivity of the samples was analyzed towards the photooxidati

Friction stir blind riveting (FSBR) is a new joining method which eliminates the need to predrill a hole for rivet insertion.A new one-sided mechanical joining process, friction stir blind riveting (FSBR) was developed to form lap-shear joints for similar and dissimilar alloy sheets in different combinations.The similar and dissimilar joints Body W

Understanding what people like about birds can help target advocacy for bird conservation.However, testing preferences for characteristics of birds is methodologically challenging, with bias difficult to avoid.In this paper we test whether preferred characteristics of birds in general are shared Bread Box by the individual bird species the same peo

Abstract Carbonate rocks undergo low-temperature, post-depositional changes, including mineral precipitation, dissolution, or recrystallisation (diagenesis).Unravelling the sequence of these events is time-consuming, expensive, and relies on destructive analytical techniques, yet such characterization is essential Default to understand their post-d
