Figure 6.5.2. 1: Map of world mining areas. Mining is defined as the extraction, from the Earth, of valuable material for societal use. Usually, this includes solid materials (e.g. gold, iron, coal, diamond, sand, and gravel), but can also include fluid resources such as oil and natural gas. Modern mining has a long relationship with modern ...

A third group of excipients for melt extrusion can be characterized as drug release modifying agents. The mechanisms of release modification are varied and frequently linked with an alteration in the matrix properties, which can lead to an increase in the drug release rate by promoting either drug diffusion and/or carrier erosion.
Furthermore, Belwal et al. reduced the basis of support and confidence of sensitive rules without modifying directly the given database. However, alteration can indirectly be performed via newly incorporating parameters associated to database transactions and association rules. New additions include M support (modified support), …
(ii) The development of greener modifying agents still represents a major challenge that should be overcome with the purpose of preparing cheaper, non-toxic, and durable AEMs. For example, the layer-by-layer approach discussed in this work consider the subsequent addition of negatively and positively charged layers on a membrane surface. …

Over the last few decades, MS treatment patterns are evolving rapidly due to the availability of various forms of Disease-Modifying Agents (DMAs). The Food and Drug Administration (FDA) has approved several DMAs for the treatment of MS, which can be further categorized by their route of administration: oral, injectable, and infusion.

Viscosity modifying agents (VMAs) are essential ingredients for the production of flowable cement-based materials. This paper presents an overview of commonly used VMAs and attempts to shed some light on the underlying physics at the origin of their mechanisms of action.
However, to avoid the segregation of concrete, either the fine material content should be increased, or a viscosity modifying agent (VMA) should be used. In this study, the possibility of producing self-compacting concrete with a lesser amount of fine material than the conventional SCC while using a polysaccharide type VMA is investigated.
Using CaO as a modifying agent greatly optimized the microstructure and physical properties of ed ceramics that were prepared using granite scrap as a raw material and SiC as a ing agent. The results of this work show that the appropriate amount of CaO can reduce the viscosity of the melt to balance the expansion drive of the …

Regarding the impact of water retention agents on the yield stress, contradictory results have been found in the literature. Some authors confirm that cellulose derivative (CE) admixtures slightly decrease the yield stress (Patural et al., 2011, Hossain and Lachemi, 2006).Patural et al. (2012) explained this decrease in base of the steric …
The management of bone lesions from advanced solid tumors and multiple myeloma typically includes use of a bone-modifying agent to reduce the risk of skeletal-related events. Recent data demonstrate that when using zoledronic acid to reduce the risk of skeletal-related events in metastatic breast cancer, metastatic prostate cancer, and …
A study by Wang examining the difficulty of supporting unsaturated polyester resin under water-contained conditions, synthesized an effective water-resistant …
The viscosity modifying agents conventionally have a negative effect on cement hydration, because the polymers adsorb on the particle surface impeding the dissolution of mineral species in the pore solution [32]. For AAM, CMS may affect the depolymerization-polyconsensation reaction process if there is an interference between …
MLA-3 agent based on hydrophobized luminophore E-515-115-G5 is more effective for modifying the characteristics of weakly fluorescent diamonds. Mixtures of …
mining losses can lead to the overstatement of tonnage. An accurate estimation of the head grade is the more critical of the two, and the author has seen a number of new mines fail …
Modifying agents for polyolefins enhance nucleation and crystallization of the polyolefins and provide improved optical and/or physical properties.
