After being subjected to acetone and toluene extraction, r-SS was separated from the sol content. The chemical structure of the r-SSs obtained by thermo-oxidative reclamation under different temperatures were characterized and compared with pure silica, as shown in Fig. 2.All the r-SSs exhibits C–H stretching vibration of –CH 2 – …

This study aimed to determine the suitable reclamation ways of post-mining magnesite. It was hypothesized that adding amendments and planting would decrease pH, increasing the nutrient availability and enhancing the soil microbial activity. Treatments included 200 g gypsum, 2 kg goat manure, and 200 g sulfur per square meter.

In this work, we show how to augment data structures with highly efficient range queries, without relying on garbage collection. We identify a property of epoch-based memory reclamation algorithms that makes them ideal for implementing range queries, and produce three algorithms, which use locks, transactional memory and lock-free …

Reclamation degree refers to the degree of devulcanization of vulcanized rubber, which is often characterized by sol content. Fig. 1(a) shows the effect of oil (10 phr) on the sol content of reclaimed waste tire rubber under different temperatures. The reclamation degree increased with the increase of the temperature, especially the ones …
