The main idea of this research is to analyse the English modals in Obama's speech semantically. modal auxiliaries selected for analysis include (Will, Would, Can, Could, and Should). All are interpreted based on framework Coates’ (1983) semantic clusters. qualitative method applied into study. auxiliary ‘can’ signifying possibility functions evoke positive emotions connotations mind all listene...

Chiral amines are an important class of organic compounds. They ubiquitous in chemistry and often serve as fundamental building blocks, versatile synthons, efficient chiral catalysts, ligands or auxiliaries asymmetric synthesis medicinal chemistry. During the past few decades, there has been remarkable progress development methods. Accordingly, synthesis, particularly catalytic enantioselective...

German and French differ in a number of aspects. Regarding the prosody-pragmatics interface, German is said to have a direct focus-to-accent mapping, which is largely absent in French--owing to strong structural constraints. We used a semi-spontaneous dialogue setting to investigate the intonational marking of Verum Focus, a focus on the polarity of an utterance in the two languages (e.g. the c...

The Universal Stanford Dependencies (USD) subordinates function words to content words. Auxiliaries, adpositions and subordinators are positioned as dependents of full verbs and nouns, respectively. Such an approach to the syntax of natural languages is contrary to most work in theoretical syntax in the past 35 years, regardless of whether this work is constituencyor dependency-based. A substan...

Now welcome, the most inspiring book today from a very professional writer in the world, selection hiring and training of dental auxiliaries. This is the book that many people in the world waiting for to publish. After the announced of this book, the book lovers are really curious to see how this book is actually. Are you one of them? That's very proper. You may not be regret now to seek for th...

The algebra of monodromy matrices for sl(n) trigonometric R-matrix is studied. It is shown that a generic finite-dimensional polynomial irreducible representation of this algebra is equivalent to a tensor product of L-operators. Cocommutativity of representations is discussed and inter-twiners for factorizable representations are written through the Boltzmann weights of the sl(n) chiral Potts m...

Lasing in induced cholesteric liquid crystal (CLC) containing highly photosensitive azo chiral dopant (ChD) and pyrromethene laser dye was investigated. Due to the absence of excitation energy transfer from the dye molecules to the molecules of ChD in such a system, a low lasing threshold was achieved. When using violet and green light-emitting diodes, reversible frequency tuning was obtained i...
