We introduce a metric homotopy theory, which we call moderately discontinuous homotopy, designed to capture Lipschitz properties of metric singular subanalytic germs. It matches with the moderately discontinuous homology theory recently developed by

We explore the existence of irreducible and reducible arc-sections in an irreducible hypersurface singularity germ along finite projections. In particular we provide examples of irreducible isolated hypersurface singularities for which no irreducible

On the generalized Nash problem for smooth germs and adjacencies of curve singularities

In this paper we explore the generalized Nash problem for arcs on a germ of smooth surface: given two prime divisors above its special point, to determine whether the arc space of one of them is included in the arc space of the other one. We prove th

Moderately Discontinuous Homology

Autor: José Edson Sampaio, Javier Fernández de Bobadilla, Maria Pe Pereira, Sonja Heinze

We introduce a new metric homology theory, Moderately Discontinuous Homology, which captures Lipschitz properties of metric subanalytic germs. The main novelty is to allow "moderately discontinuous" chains, which are specially advantageous for captur

Photosynthetic activity and protein overexpression found in Cr(III)-tolerant cells of the green algae Dictyosphaerium chlorelloides

Autor: Maria Pe Pereira, C.M. Bartolomé, S. Sánchez-Fortún

Publikováno v: Chemosphere. 108:274-280

Chromium is an important constituent in effluents obtained from chromium plating industries. Due to the highly toxic nature of Cr(VI), attention has been shifted to less hazardous Cr(III) electroplating processes. This study evaluated aquatic toxicit

Peracetic acid disinfectant efficacy against Pseudomonas aeruginosa biofilms on polystyrene surfaces and comparison between methods to measure it

Autor: Maria Pe Pereira, M.C. Bartolomé, A. D’ors, M.C. Martín-Espada, S. Sánchez-Fortún

Publikováno v: LWT - Food Science and Technology. 56:58-61

In food industry, biofilms are a source of recalcitrant contaminations, being possible sources of public health problems. The aims of this study were evaluate the disinfectant efficacy of peracetic acid against Pseudomonas aeruginosa biofilms grown o

Bioadsorption and bioaccumulation of chromium trivalent in Cr(III)-tolerant microalgae: A mechanisms for chromium resistance

Autor: S. Sánchez-Fortún, M.C. Bartolomé, Maria Pe Pereira

Publikováno v: Chemosphere. 93:1057-1063

Anthropogenic activity constantly releases heavy metals into the environment. The heavy metal chromium has a wide industrial use and exists in two stable oxidation states: trivalent and hexavalent. While hexavalent chromium uptake in plant cells has

Fibonacci Numbers and Self-Dual Lattice Structures for Plane Branches

Publikováno v: Bridging Algebra, Geometry, and Topology ISBN: 9783319091853

Consider a plane branch, that is, an irreducible germ of curve on a smooth complex analytic surface. We define its blow-up complexity as the number of blow-ups of points needed to achieve its minimal embedded resolution. We show that there are F 2n�

Influence of pH on the survival of Dictyosphaerium chlorelloides populations living in aquatic environments highly contaminated with chromium

Autor: M. Carmen Bartolomé, S. Sánchez-Fortún, Maria Pe Pereira

Publikováno v: Ecotoxicology and environmental safety. 98

The accommodation of photosynthetic organisms to adverse conditions, such as pH changes in the aquatic environment, and their response to aquatic pollutants is essential to develop future biosensors. The present study reports the ability of both Cr(V
