An extension of Berwald's inequality and its relation to Zhang's inequality

In this note prove the following Berwald-type inequality, showing that for any integrable log-concave function f:Rn→[0, ∞)and any concave function h :L →[0, ∞), where L ={(x, t) ∈Rn×[0, ∞) :f(x) ≥e−t‖f‖∞}, then p→⎛⎝1Γ(1 +p)∫Le−tdtdx∫Lhp(x, t)e−tdtdx⎞⎠1p is decreasing in p ∈(−1, ∞), extending the range of pwhere the monotonicity is known to hold true.As an application of this extension, we will provide a new proof of a functional form of Zhang’s reverse Petty projection inequality, recently obtained in [2]

A boiler room in a 600-bed hospital complex: study, analysis, and implementation of energy efficiency improvements

Producción CientíficaThe aim of energy efficiency is to use less energy to provide the same service. In hospitals, energy efficiency offers a powerful and cost-effective tool to reduce greenhouse gas emissions, fuel consumption, and also running costs. Over a six-month period, the six gas-fired boilers that provide both a hospital’s heat and hot water were monitored. Analysis of the data obtained led to several actions being implemented in the hospital boiler room control system to improve the efficiency of the heat production system. Comparative studies were conducted, during similar weather periods, of the performance of the hospital’s hot water production system before and after the controls were implemented. Results indicate that the control actions applied proved to be effective. Finally; the paper offers a financial; primary energy saving and CO2 reduction analysis that points to a 3,434.00 €/week savings in natural gas consumption; and a cut in CO2 emissions of 20.3 tons/week; as compared to the reference facility

Functional architecture of Escherichia coli: new insights provided by a natural decomposition approach

The E. coli transcriptional regulatory network is shown to have a nonpyramidal architecture of independent modules governed by transcription factors, whose responses are integrated by intermodular genes

Biblioteca y empoderamiento ciudadano

The twenty-first century libraries are adapting their roles and needs to the new demands of the society in which we live. The role of libraries is expanding to remain relevant institutions in a new ecosystem is constantly changing. The information society offers great possibilities to individuals, but also increases the multiple gaps between citizens and countries. The library in this context is one of the most important strategic resources to mitigate these difficulties and encourage individuals and communities to participate fully in the possibilities offered by the so-called information technologies. Thus libraries are drawing up plans and spaces to empower their communities with innovative services that have been adapted gradually to the new situation. In line with this the role of the librarian involves expanding its capabilities as one of the key resources of the library of the future. The paper analyzes these changes and how libraries are responding positively in favor of its users and their comunidades

Bibliotecas y empoderamiento ciudadano

[ES] Las bibliotecas del siglo XXI están adaptando sus funciones y necesidades a las nuevas demandas de la sociedad en la que vivimos. El papel de las bibliotecas está ampliándose para seguir siendo instituciones relevantes en un nuevo ecosistema en constante cambio. La sociedad de la información brinda grandes posibilidades a los individuos, pero también acrecienta las múltiples brechas entre los ciudadanos y países. La biblioteca en este contexto es una de los recursos estratégicos más importantes para mitigar estas dificultades e impulsar a las personas y comunidades a participar plenamente en las posibilidades que brindan las llamadas tecnologías de la información. De este modo las bibliotecas están diseñando planes y espacios para empoderar a sus comunidades con servicios innovadores que se han ido adaptando progresivamente a esta nueva situación. En consonancia con ello el papel del bibliotecario implica la ampliación de sus capacidades como uno de los recursos clave de la biblioteca del futuro. En el documento se analizan estos cambios y como las bibliotecas están respondiendo positivamente en favor de sus usuarios y sus comunidades.

Microbenthic Net Metabolism Along Intertidal Gradients (Cadiz Bay, SW Spain): Spatio-Temporal Patterns and Environmental Factors

Microphytobenthos (MPB), the photosynthetic primary producing component of microbenthos, shows variable patterns in its biomass distribution along the intertidal gradient as a result of the interactions of factors such as light, tides, temperature, and grazing pressure. These patterns have been studied more extensively in northern European estuaries than southern European coastal systems. Even less information is available regarding temporal changes in MPB primary production rates in these systems. For this reason, we followed the seasonal changes in net production in light and dark respiration rates (determined by oxygen microelectrodes) and MPB biomass (estimated by sediment chlorophyll a) along the intertidal gradient of the inner Cadiz Bay during a year. Sediment cores were collected along two transects (five sampling stations per transect) with distinct sediment granulometry: one muddy [Puerto Real (PR)] and one muddy-sandy transect [San Fernando (SF)]. Our results show that MPB biomass and net production increased seawards reaching their maxima in winter. In contrast to what is observed in northern European systems, the higher solar irradiance and temperatures occurring in summer in southern Spain likely inhibit MPB production. In Cadiz Bay, spatial patterns of MPB biomass and net production depended on season and location due to the environmental heterogeneity observed. Environmental variables, analyzed by principal component analysis (PCA), were used to explain the variability of MPB metabolism by multiple regression. Selected principal component (PC) axes explained 60% of the net production in light and 41% of the dark respiration rates variability in PR, while they only accounted for 25% of the same rates in SF. The differences observed between transects and the variability in the environmental variables explaining them highlight the importance of considering the spatial heterogeneity of our system to estimate the contribution of MPB to the inner Cadiz Bay productivity. In our case, this contribution is significant accounting for up to 49% of the total benthic production of the inner Cadiz Bay intertidal sediments, confirming previous global estimates
