Improving the Properties of Arthma Sand for Using In the Sand Moulding
Engineering and Technology Journal, 2005 The aim of the present research is to improve properties of Arthma sand through the addition of different materials for using it in sand casting processes. After preparing the master mixture from (Arthma sand, 5% Bentonite, 5% water), then we add different percents ranging between (2-8)% of the added maters which were phenol, phenol with Boric acid ...

Energy Science &Engineering, EarlyView.Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Optimizing germination and cultivation of edible halophytes using effluents from an IMTA system
Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND Halophytes offer nature‐based solutions to food insecurity and soil degradation, while their integration into integrated multi‐trophic aquaculture (IMTA) systems promotes circular economy practices. This study aimed to optimize the germination and cultivation of edible halophytic species, namely Limbarda crithmoides, Suaeda vera and
