A Theoretical Study of the Diels-Alder Reaction between 3-nitrofuran and Different Dienes Developed in Ionic Liquids
(ScienceDomain international, 2016-07)
In this study the reactivity of 3-nitrofuran acting as electrophile in their reactions with different dienes, was analyzed in theoretical form. Specifically, the mechanism of each DA reaction was explored. Moreover, ...
Interaction, Diffusion, and Fertility Transition in Costa Rica: Quantitative and Qualitative Evidence
(1999)
This chapter examines the role played by diffusion through social interaction in the Costa Rican fertility transition. The literature about the causes of fertility transition has traditionally focused on the socio-economic ...
Theoretical motivation for studying superstrings

On the Nucleophilicity of Boryllithium Compounds. A Theoretical Study
(AMER CHEMICAL SOC, 2009)
Boron compounds are widely used in synthetic chemistry. The synthesis of the compounds is relatively easy, presenting thermodynamic stability and synthetic versatility. Almost all of them show electrophilic reactivity. ...
Theoretical and experimental evaluation of the influence of the length of drill rods in the SPT-T test
(2010-01-01)
The influence of soil drill rod length on the N value in the SPT-T test has been studied extensively by Mello (1971), Schmertmann & Palacios (1979), Odebrecht et al. (2002) and Cavalcante (2002). This paper presents an ...
