Cancer Nexus, EarlyView.ABSTRACT Objective This single‐center retrospective cohort study evaluated whether, among patients with stage IV cancer who participated in a pragmatic “alkalization therapy”—defined as a low potential renal acid load diet plus oral sodium bicarbonate and/or potassium/sodium citrate—urinary pH was associated with long‐term survival.

ChemSusChem, Volume 18, Issue 6, March 15, 2025.The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Alkaline and Ultra-Alkaline Rocks, Carbonatites, and Kimberlites
, 2013 The petrology and origin of some rare rock types that have high to very high alkalis, including kimberlites to phonolites, are discussed in this chapter. Carbonatites are also included here because they are commonly associated with alkaline igneous rocks.

Deep Underground Science and Engineering, EarlyView.Joint orientation significantly affects P‐wave velocity, with the highest velocity at zero‐degree angles, decreasing to 30° as the angle increases. The velocity increases slightly from 30 to 45 degrees but sharply decreases from 45 to 90 degrees. Abstract Determination of the required parameters in different science contexts using the ultrasonic wave ...

Deep Underground Science and Engineering, EarlyView.Based on the 90 datasets, ERT and four optimization algorithms were used to build four hybrid models to predict the UCS of the backfill body. The SMA‐ERT model was the most effective model, and it can reliably guide the design of the backfill ratio parameters. Abstract This study analyzed the feasibility of using titanium (Ti) tailings as a backfilling
