Electricity production in microbial fuel cell with Cu-B alloy as catalyst of anode

2015

Considering the increasing standard of living, the energy consumption increases as well, and so does waste production. However, there is a possibility to combine energy production and wastewater treatment. A device that can accomplish this task is a microbial fuel cell. In microbial fuel cells activated sludge bacteria can be used for electricity production during wastewater treatment. One of the problems with microbial fuel cells is a low current density of those energy sources. Nonetheless, it is possible to increase the current density by using the catalyst for fuel electrode (anode) – as long as a low cost catalyst can be found. The possibility of wastewater treatment using the Cu-B all…

Response of Soil Microbial Communities to Iron-Porphyrin Catalytic Amendments.

2010

Intensive agricultural practices strongly increase CO2 emission from soil. Synthetic metal-porphyrins were shown to significantly decreased CO2 emission from soil due to an in-situ catalysis of oxidative polymerization of soil organic matter. This research aimed to assess the effects of iron-porphyrin (POR) amendments on soil microbial communities in three arable soils under wheat and maize cropping located in Naples, Turin and Piacenza, characterized by different pedological and climatic conditions. Bulk-soil and rhizo-soil were sampled during 4 years and the microbial groups directly involved in organic matter (OM) mineralization and in key processes of the nitrogen cycle were examined. M…

Migración y salud: diferencias en mortalidad perinatal

2019

INTRODUCCIÓN Más de un billón de personas en el mundo migraron en 2018, 258 millones eran migrantes internacionales, el 48,4% fueron mujeres. España está entre los 10 países con mayor número de migrantes entre 1990 y 2017. Las tasas de mortalidad infantil y perinatal son marcadores del estado de salud poblacional, y clave en la evaluación de la calidad asistencial. La Comunitat Valenciana cuenta con un registro de mortalidad perinatal, con datos de muertes desde la semana 22 de gestación hasta los 28 días de vida. OBJETIVO Analizar la evolución de la mortalidad perinatal en mujeres migrantes y españolas residentes en la Comunitat Valenciana en 2006-2017, y sus causas prevenibles usando dive…

Aquaculture as a source of empirical evidence for coevolution between CRISPR-Cas and phage

2019

So far, studies on the bacterial immune system CRISPR-Cas and its ecological and evolutionary effects have been largely limited to laboratory conditions. While providing crucial information on the constituents of CRISPR-Cas, such studies may overlook fundamental components that affect bacterial immunity in natural habitats. Translating laboratory-derived predictions to nature is not a trivial task, owing partly to the instability of natural communities and difficulties in repeated sampling. To this end, we review how aquaculture, the farming of fishes and other aquatic species, may provide suitable semi-natural laboratories for examining the role of CRISPR-Cas in phage/bacterium coevolution…

Fractal-like Hierarchical CuO Nano/Microstructures for Large-Surface-to-Volume-Ratio Dip Catalysts

2022

Dip catalysts are attracting interest in both academia and industry for catalyzing important chemical reactions. These provide excellent stability, better recoverability, recyclability, and easy scale-up. Using the unique microstructures of leaf skeletons, we present a fractal-like hierarchical surface that can be used as a versatile and efficient dip catalyst. Copper oxide microcactuses with nanoscalar features were fabricated onto the Bauhinia racemosa leaf skeletons via a combination of physical vapor deposition, electroplating, and chemical oxidation methods. The coated leaf skeletons have a very high surface area, and the three-dimensional (3D) morphology allows the reactants to encoun…

How amniotic fluid shapes early odor-guided responses to colostrum and milk (and more)

2016

Revue; Among the multiple transitions that characterize mammalian development, birth certainly is the most abrupt and spectacular. It is also the most challenging for newborns when one considers their high mortality rates in any mammalian species. Although evolution has selected newborn organisms that possess the physiological and behavioral keys leading to adapt to this harsh psychobiological challenge, their capabilities cannot be considered separately from the maternal organism and the environment she creates. Mammalian females provide indeed passive (physiological) and/or active (behavioral) assistance to complement and boost their offspring’s capacities. One notable strategy of mammali…

Le carriere universitarie degli studenti negli atenei statali e non statali in Italia

2020

Negli ultimi anni si è assistito ad un incremento della competizione tra gli atenei per “accaparrarsi” gli studenti, a cui si aggiunge una sempre maggiore attività di promozione e di reclutamento degli studenti delle università non statali (telematiche e non). Le università non statali, altrimenti denominate “libere Università”, sono promosse sia da enti di diritto privato che da enti pubblici (regioni, province, comuni). Esse sono legalmente riconosciute dal Ministero dell'Istruzione dell'Università e della Ricerca, e autorizzate a rilasciare titoli accademici, relativi all’ordinamento universitario, di valore legale identico a quelli rilasciati dalle università statali. La letteratura ha …

Les actes capitulars de la Seu de Xàtiva (segle XVIII). Estudi i edició

2015

Les actes capitulars de la Seu de Xàtiva (segle XVIII). Estudi i edició, constitueix un estudi sobre la importància del llenguatge administratiu eclesiàstic dintre de l’edat moderna, un període que havia estat tradicionalment menystingut sobretot a partir de denominacions que no eren massa propícies. És de tots sabut el tractament negatiu que ha rebut la llengua catalana i la seua literatura produïda entre els segles XVI i XVIII —tant des del punt de vista dels escrits més creatius com des dels altres camps: escriptura privada, textos administratius, judicials, processals, legislatius, eclesiàstics... No fa encara massa, hom sempre emprava el terme «Decadència» per a caracteritzar aquest pe…

The Role of Fc Receptors on the Effectiveness of Therapeutic Monoclonal Antibodies.

2021

Since the approval of the first monoclonal antibody (mAb) in 1986, a huge effort has been made to guarantee safety and efficacy of therapeutic mAbs. As of July 2021, 118 mAbs are approved for the European market for a broad range of clinical indications. In order to ensure clinical efficacy and safety aspects, (pre-)clinical experimental approaches evaluate the respective modes of action (MoA). In addition to antigen-specificity including binding affinity and -avidity, MoA comprise Fc-mediated effector functions such as antibody dependent cellular cytotoxicity (ADCC) and the closely related antibody dependent cellular phagocytosis (ADCP). For this reason, a variety of cell-based assays have…
