Stability of silver nanoparticles: agglomeration and oxidation in biological relevant conditions
(Springer, 2017-05)
Silver nanoparticles (Ag-NP) are the most used nanomaterial in consumer products due to the intrinsic antimicrobial capacity of silver. However, Ag-NP may be also harmful to algae, aquatic species, mammalian cells, and ...
Perfect edge domination: hard and solvable cases
(Springer, 2018-05)
Let G be an undirected graph. An edge of Gdominates itself and all edges adjacent to it. A subset E′ of edges of G is an edge dominating set of G, if every edge of the graph is dominated by some edge of E′. We say that E′ ...
b-Coloring is NP-hard on Co-bipartite Graphs and Polytime Solvable on Tree-Cographs
(Springer, 2015)
A b-coloring of a graph is a proper coloring such that every color class contains a vertex that is adjacent to all other color classes. The b-chromatic number of a graph , denoted by , is the maximum number such that admits ...
Nanopartículas de dióxido de titânio e prata imobilizadas em filmes de celulose não modificada: preparação, caracterização e aplicação na degradação de poluentes
(Universidade Federal de São Paulo, 2022-08-05)
Visando o emprego desses nanomateriais como nanocatalisadores heterogêneos em processos que envolvam a degradação de poluentes em meios aquosos, a imobilização dessas nanopartículas em filmes de celulose, o biopolímero ...
The non planar vertex deletion of C-n x C-m
(Charles Babbage Res CtrWinnipegCanadá, 2005)
PLANIFICACIÓN ÓPTIMA DISCRETA PARA PROBLEMAS NP-COMPLETOS MEDIANTE ALGORITMOS INMUNOLÓGICOS ARTIFICIALES
(2011-06-16)
The purpose of this thesis work is to present a new algorithm that helps in solving combinatorial
optimization problems of the NP-complete order which is based on the human
immune system, being its abstraction the ...
Revisiting the fundamentals of p-nitrophenol analysis for its application in the quantification of lipases activity. A graphical update
(Universidad Nacional (Costa Rica), 2020-07-31)
p-Nitrophenol (pNP) is a widely used compound for analytical determinations of several esterases (EC. 3.1.1.X), including lipases (E.C. 3.1.1.3). Most enzymatic measurements employ pNP derivatives such as ...
On neighborhood-Helly graphs
(Elsevier Science, 2017-01)
A family F of subsets of some set is intersecting when sets of F pairwise intersect. The family F is Helly when every intersecting subfamily of it contains a common element. In this paper we examine the families of vertex ...
