Deep Processing – This takes two forms. 3. Semantic processing, which happens when we encode the meaning of a word and relate it to similar words with similar meaning. Deep processing involves elaboration rehearsal which involves a more meaningful analysis (e.g. images, thinking, associations, etc.) of information and leads to …

Experimental results indicated that the microwave deep drying process exists three segments: increasing-rate, falling-rate and brief constant-rate segment. The drying time decreased and drying rate increased with microwave output power level increase, while the microwave penetration depth in lignite was affected by sample …
Coal mining - Extraction, Processing, Pollution: In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements. When this material decays under water, in the absence of oxygen, the carbon …

Deep processing is a concept in cognitive psychology that refers to a method of learning where an individual engages with information in a meaningful way, leading to better retention and recall. This approach contrasts with shallow processing, where attention to detail is minimal and understanding is surface-level. The origins of deep processing …
1. Introduction. Lignite is one of the most abundant types of coal, and its total proven reserves in the world is 195 billion tons, accounting for 22.67 % of the total coal reserves [1].Lignite has a low degree of coalification under the influence of coal formation age, with the characteristics of high moisture content (30–60 %), high ash content …
Lignite is the lowest rank of coal. It is a peat that has been transformed into a rock, and that rock is a brown-black coal. Lignite sometimes contains recognizable plant structures. By definition it has a heating value of less than 8300 British Thermal Units per pound on a mineral-matter-free basis.
A production technology has been developed for strong briquets (with high CSR and M25) based on coke derived from Kansko-Achinsk lignite.
