From geometric quantization to Moyal quantization
(1995-06)We show how the Moyal product of phase-space functions, and the Weyl correspondence between symbols and operator kernels, may be obtained directly using the procedures of geometric quantization, applied to the symplectic ... -
From Ideality to Simplicity: A Robust and Affordable Hydrogen Reference Electrode
(2020-02-01)In electrochemistry, the concept of a reference electrode is fundamental. Introductory courses might mention the standard hydrogen electrode (SHE), its working principle, and its theoretical design; however, chances are ... -
¿Funcionan realmente los microorganismos de montaña (MM) como estrategia de biofertilización? Un enfoque de ingeniería de biosistemas
(2017-06-29)El uso de microorganismos en aplicaciones ingenieriles, en particular desde un contexto de ingeniería de biosistemas tropicales, es útil para comprender el efecto de variables que determinan la dinámica microbiológica ... -
Function of the upper tangle in webs of young Leucauge argyra (Araneae: Tetragnathidae)
(2011)Ontogenetic changes in web structure occur in many spiders of different families, but the functional adaptation of differences in web structure is unknown for most species. We describe the ontogenetic changes in web structure ... -
Functional aspects of genital differences in Leucauge argyra and L. mariana (Araneae: Tetragnathidae)
(2013)Morphological studies have documented the tendency for male genitalia to diverge rapidly compared to other body parts in many animal groups, including spiders. But documentation of how differences in genital structures of ... -
Functional changes in web design along the ontogeny of two orb-weavers
(2017-08-01)Orb webs evolved primarily to capture prey, though they also have other functions. Recently, it has been argued that the orb web does not work as a functional unit, but instead some sections or components have presumably ... -
Una fundamentación instrumental de la Aritmética
(1990)Desde el punto de vista de la génesis histórica y psicológica del conocimiento humano, poca duda cabe que los números naturales van siendo elaborados como referente social en el proceso de conteo. En este artículo se ... -
Fundamentals of silicene
(2017-08-02)Silicene is a single atomic layer of silicon (Si) much like graphene, the first example of an elemental twodimensional (2D) nanomaterial whose study led to the 2010 Nobel Prize in Physics. Until 2010 or so, the only known ... -
Fundamentos de Química Orgánica
(1985)Este libro es una introducción a la Química Orgánica, para estudiantes de carreras médicas, Microbiología, Biología, Agricultura, Veterinaria. Llena un vacío entre textos escolares y libros de texto de la carrera de Química. -
Fungal and Bacterial Co-Bioaugmentation of a Pesticide-Degrading Biomixture: Pesticide Removal and Community Structure Variations during Different Treatments | SpringerLink
(Springer, 2021)Biopurification systems (BPS) are employed for the treatment of pesticide-containing wastewaters. In this work, a biomixture (active core of BPS) complemented by the addition of the fungus Trametes versicolor was evaluated ... -
Fungal bioaugmentation of two rice husk-based biomixtures for the removal of carbofuran in on-farm biopurification systems
(2016-02)The ligninolytic fungus Trametes versicolor was employed in the bioaugmentation of compost- (GCS) and peat-based (GTS) biomixtures for the removal of the insecticide-nematicide carbofuran (CFN). Among several lignocellulosic ... -
Fungal communities in feces of the frugivorous bat Ectophylla alba and its highly specialized Ficus colubrinae diet
(2022)Background: Bats are important long-distance dispersers of many tropical plants, yet, by consuming fruits, they may disperse not only the plant’s seeds, but also the mycobiota within those fruits. We characterized the ... -
Fungal Communities in Sediments Along a Depth Gradient in the Eastern Tropical Pacific
(2020-11-06)Deep waters represent the largest biome on Earth and the largest ecosystem of Costa Rica. Fungi play a fundamental role in global biogeochemical cycling in marine sediments, yet, they remain little explored. We studied ... -
Fungal Endophytes and Their Bioactive Compounds in Tropical Forests of Costa Rica
(2021-04-15)We present a glimpse of the diversity of endophytic fungi in the tropical forests of Costa Rica and some examples of bioactive compounds obtained from them. We include the characterization of isolates carried out mainly ... -
FungalTraits: a user-friendly traits database of fungi and fungus-like stramenopiles
(2021-01-19)The cryptic lifestyle of most fungi necessitates molecular identification of the guild in environmental studies. Over the past decades, rapid development and affordability of molecular tools have tremendously improved ... -
Fungi for the bioremediation of pharmaceutical-derived pollutants: A bioengineering approach to water treatment
(2021-07-01)The excessive amount of pharmaceutical compounds (PhCs) released into aquatic environments poses a risk to humans, wildlife, and environmental health. It is a serious problem that requires urgent attention. In this work, ... -
Fungi in aquatic ecosystems
(2019-03)Fungi are phylogenetically and functionally diverse ubiquitous components of almost all ecosystems on Earth, including aquatic environments stretching from high montane lakes down to the deep ocean. Aquatic ecosystems, ... -
Fungi increases kelp (Ecklonia radiata) remineralisation and dissolved organic carbon, alkalinity, and dimethylsulfoniopropionate (DMSP) production
(2023-09)Fungi are key players in terrestrial organic matter (OM) degradation, but little is known about their role in marine environments. Here we compared the degradation of kelp (Ecklonia radiata) in mesocosms with and without ...
