The Frattini p-subalgebra of a solvable Lie p-algebra [PDF]
, 1997 In this paper we continue our study of the Frattini p-subalgebra of a Lie p-algebra L. We show first that if L is solvable then its Frattini p-subalgebra is an ideal of L. We then consider Lie p-algebras L in which L^2 is nilpotent and find necessary and

Risk of SARS-CoV-2 Infection and Hospitalisation in Immunocompromised Children: A Population-Based Cohort Study in Italy and Norway. [PDF]
Acta PaediatrABSTRACT Aim Immunocompromised children (IC) were presumed to be at higher risk of SARS‐COV‐2 infection and severe COVID‐19, but population‐based evidence is limited. We assessed infection risk, COVID‐19 hospitalisation, and severe outcomes in IC compared with children with and without other high‐risk conditions.

Is the clay "exchange capacity" concept wholly applicable to pozzolans?
Materiales de Construccion, 2004 One of the most characteristic properties of clays is their "cation exchange capacity", otherwise known as their "exchange capacity ". The research reported in this article shows that for various reasons some natural and artificial pozzolans exhibit this

Pozzolanic activity evaluation of spent bleaching earth ash strength activity index, frattini test and saturated lime test [PDF]
, 2022 The process of palm oil refining produces spent bleaching earth (SBE) as a waste by-product. In Malaysia, this waste usually ends up in landfills.

Elementary Lie Algebras and Lie A-Algebras. [PDF]
, 2007 A finite-dimensional Lie algebra L over a field F is called elementary if each of its subalgebras has trivial Frattini ideal; it is an A-algebra if every nilpotent subalgebra is abelian. The present paper is primarily concerned with the classification of

Characterization of sugar cane bagasse ash as supplementary material for Portland cement
Ingeniería e Investigación, 2014 Sugar Cane Bagasse is a by-product of the sugar agroindustry; it is partly used as fuel. However, bagasse ash (SCBA) is considered waste, which creates a disposal problem. Furthermore, if sugar cane bagasse is burned under controlled conditions, the SCBA

European Management Review, EarlyView.Abstract Corporate purpose is gaining momentum in contemporary business communities, yet it often appears shrouded in ambiguity. Although research is growing in popularity, the analysis of corporate purpose from the perspective of strategic leaders remains an unexplored domain.

Journal of Management Studies, EarlyView.Abstract In previous research, scholars have often highlighted the important role of leaders in defending and protecting a historical organizational purpose. However, adopting such a ‘backward‐looking’ perspective, researchers have devoted much less attention to understanding how an organizational purpose can be deliberately changed and leveraged to ...
