Infinitesimal Probability Theory with Amalgamation
We introduce the notion of operator-valued infinitesimal independence for the free, Boolean, and monotone cases. We show that operator-valued infinitesimal free (respectively Boolean, monotone) independence is equivalent to the operator-valued free (respectively Boolean, monotone) independence over …

Amalgamation in varieties of algebras
… the set. This property of groups, known as the amalgamation property was generalized to a universal-algebraic setting by R. Fralsse in 1954, and the important question as to which varieties satisfied the amalgamation property arose. While some of the answers to this question were positive (such …

Congruences and amalgamation in small lattice varieties
… many varieties of algebras do not satisfy the Amalgamation Property, George Grätzer introduced the concept of an amalgamation class of a variety . The bulk of this dissertation is concerned with the amalgamation classes of residually small lattice varieties, with an emphasis on lattice …

Congruences on lattices (with application to amalgamation)
… The last chapter (Chapter 6) characterizes the amalgamation class of a variety B generated by a B-lattice, B, as the intersection of sub direct products of B, 2-congruence extendible members of B and 2-chain limited members of B. To this end we consider 2-congruence extendibility in Chapter 4 …

The tectonic evolution of the Southern Granulite Terrane of India and its role in the amalgamation of Gondwana.
… likely linked to the final stages of Gondwana amalgamation. This study also suggest that care should be taken when regarding the regional-scale structural fabrics of the PCSS as being associated with the latest Neoproterozoic metamorphism. The Southern Granulite Terrane records two major …

A study of alternative techniques to mercury amalgamation for gold extraction in artisanal and small-scale gold mining
… particularly in developing countries. Mercury amalgamation is the method of choice to recover gold in ASGM. This method consists of contacting the gold found within an ore with mercury to form an alloy i.e., the mercury-gold amalgam and subsequently burning off mercury to recover the gold in a …

A Study Of Cyanide-Glycine Synergistic Lixiviant And The Igoli Process As Suitable Replacements For Mercury Amalgamation In Artisanal And Small-Scale Gold Mining
… free-milling ores, in a process called mercury amalgamation. This is the go-to technology in most ASGM operations owing to its availability and ease of operation. However, mercury amalgamation has low recoveries in the range of 30-33% of gold from the otherwise rich gold ores typically mined in …

Plasmonic gold nanostructures: optical properties and application in mercury detection
… ligand hybrid structures and amalgamation of single immobilised gold nanorods upon chemical and upon electrochemical reduction of Hg2+ ions. The amalgamation approach showed large potential with extraordinary shifts of the nanorods’ scattering spectra upon exposure to reduced …

Identifying strategies for effective artisanal and small-scale gold mining interventions in Kadoma-Chakari, Zimbabwe
… that as much as 90% of the mercury contained in amalgamation tailings at mills in Kadoma-Chakari is dissolved during passive vat cyanidation. Mercury traps placed after copper amalgamation plates and centrifuges could reduce the amount of mercury subjected to cyanidation, but mercury can be kept …

Methods for Computing Genus Distribution Using Double-Rooted Graphs
… of a graph obtained through the vertex amalgamation of a double-rooted graph with a single-rooted graph, and to show how these can be used to obtain recurrences for the genus distribution of iteratively growing infinite graph families. (ii) to compute the genus distribution of a graph …

Unilinear Residuated Lattices
… unilinear residuated lattices are studied and amalgamation property and strong amalgamation properties are proved or disproved, depending on if there are extra constants in the language. We give two general constructions of ⊤-unital unilinear residuated lattices, provide an axiomatization and a …

Varieties of lattices
… in the last chapter is a characterisation of the amalgamation classes of certain congruence distributive varieties and the result that there are only three lattice varieties which have the amalgamation property.
