Microbial communities in full-scale woodchip bioreactors treating aquaculture effluents.

2021

Woodchip bioreactors are being successfully applied to remove nitrate from commercial land-based recirculating aquaculture system (RAS) effluents. In order to understand and optimize the overall function of these bioreactors, knowledge on the microbial communities, especially on the microbes with potential for production or mitigation of harmful substances (e.g. hydrogen sulfide; H2S) is needed. In this study, we quantified and characterized bacterial and fungal communities, including potential H2S producers and consumers, using qPCR and high throughput sequencing of 16S rRNA gene. We took water samples from bioreactors and their inlet and outlet, and sampled biofilms growing on woodchips a…

12q21 Interstitial Deletions: Seven New Syndromic Cases Detected by Array-CGH and Review of the Literature.

2022

Interstitial deletions of the long arm of chromosome 12 are rare, with a dozen patients carrying a deletion in 12q21 being reported. Recently a critical region (CR) has been delimited and could be responsible for the more commonly described clinical features, such as developmental delay/intellectual disability, congenital genitourinary and brain malformations. Other, less frequent, clinical signs do not seem to be correlated to the proposed CR. We present seven new patients harboring non-recurrent deletions ranging from 1 to 18.5 Mb differentially scattered across 12q21. Alongside more common clinical signs, some patients have rarer features such as heart defects, hearing loss, hypotonia an…

The Role of Family on Pathways to Acquiring Early Reading Skills In Lusaka’s Low-Income Communities

2014

This paper reports findings from the study that examined the role of family in children’s acquisition of early reading skills. We recruited 72 first-grade learners and their parents from low-income Zambian families for the study. In response to a home literacy questionnaire, parents reported on their reading attitudes and family literacy environment. Children’s early reading skills were assessed using two early reading tests (orthographic awareness and decoding competence), both conducted at two different points during the year. Regression analyses of pretest and gain scores revealed that parental reading attitude and family literacy environment significantly predicted early reading skills.…

¿Coinciden las expectativas escolares de la familia y del profesorado acerca del alumnado de origen inmigrante?

2014

Esta investigación pretende conocer las expectativas de futuro de familias inmigrantes y profesorado sobre los estudiantes de Educación Primaria en la Comunidad Autónoma del País Vasco. El proceso de asentamiento de la primera generación de inmigrantes transnacionales en la última década pone de manifiesto la necesidad de seguir de cerca los procesos de incorporación de sus hijos/as en el nuevo país. Se han estudiado las expectativas de 302 familias inmigrantes y del profesorado tutor de sus hijos en referencia a logros académicos y profesionales, aprendizaje de lenguas y desarrollo de las relaciones sociales del alumnado. Se manifiesta que existe una relación directa entre las expectativa…

Structural, thermal and photomagnetic properties of spin crossover [Fe(bpp)2]2+ salts bearing [Cr(L)(ox)2]- anions

2009

International audience; This paper is divided into two parts: in the first part, the influence of solvate molecules on the magnetic properties of spin crossover salts of [Fe(bpp)(2)][Cr(L)(ox)(2)]ClO(4) x nS (bpp = 2,6-bis(pyrazol-3yl)pyridine; L = 2,2'-bipyridine (bpy) or 1,10-phenanthroline (phen); ox = oxalate dianion; S = solvent) is analyzed. The second part is devoted to the photomagnetic properties of the previously reported [Fe(bpp)(2)][Cr(L)(ox)(2)](2) family of compounds. The study describes the crystal structure, differential scanning calorimetry (DSC) and magnetic properties of [Fe(bpp)(2)][Cr(bpy)(ox)(2)]ClO(4) x EtOH x 4 H(2)O (1) and [Fe(bpp)(2)][Cr(phen)(ox)(2)]ClO(4) x 1.5 …

Cultivation ofZymomonas mobilis 113 S at Different Mixing Regimes and their Influence on the Levan Formation

2001

The Zymomonas mobilis I 13 S strain was cultivated in a bioreactor with a working volume of 1.4 I at different stirring regimes in a 15% initial sucrose medium The levan obtained in the fermentation process was analyzed by gel filtration. Because the sucrose/biomass ratio in the fermentation broth decreased to below 300 g/g, the insufficient concentration of sucrose might have decreased the concentration of levan. Besides the growth characteristics of the population, the mixing intensity and flow structure were also found to influence the molecular mass of levan. At 600 rpm, the microorganisms produced levan with a molecular mass lower than at 300 rpm. The stirring of a fermentation broth w…

Chitosan films for the microbiological preservation of refrigerated sole and hake fillets

2013

The effect of chitosan films for shelf-life extension of fresh fillets of hake (Merluccius merluccius) and sole (Solea solea) was evaluated over a 15-day storage at 4 ± 1 °C. Fish fillets wrapped in a chitosan matrix were individually packaged in air (AP) and under vacuum (VP). Microbiological analyses (total aerobic mesophilic bacteria, Pseudomonas, H2S-producing bacteria, lactic acid bacteria, Enterobacteriaceae and Listeria monocytogenes were carried out during the shelf-life. The microbial species were inhibited (p < 0.05) by the presence of chitosan films, especially under VP conditions. A significant (p < 0.05) increase of the lag phase and a reduction of the final microbial populatio…

Computations on non-covalent assemblies: Supramolecular organization and transport properties

2022

The aim of this Thesis is to rationalize, from a theoretical perspective, the structural, electronic, optical and transport properties of different electroactive non-covalent assemblies of special relevance in the field of organic electronics. The ultimate goal is to establish valuable supramolecular structure-property relationships. In particular, this Thesis is focused on three types of systems: hole transporting materials (HTM), donor–acceptor supramolecular complexes and supramolecular polymers. For each system, the spotlight has been put on different relevant electronic processes. In the first part, the structural organization of several supramolecular polymers is studied. In particula…
