Assessing the efficiency of zeolites in BTEX adsorption: Impact of pore structure and humidity in single and multicomponent systems
Among volatile organic compounds (VOCs), benzene, toluene, ethylbenzene and o-xylene (BTEX) have attracted global attention because of their high toxicity to the environment and human health. Adsorption is considered one ...
Diversificación y diferenciación en las facultades de economía y empresa españolas
Este estudio comprueba si la adaptación al Espacio Europeo de Educación Superior (EEES) ha influido en la diversificación y diferenciación de los estudios de las Facultades de Economía y Empresa españolas (FEE), y determina ...
Pharmacological modulation of behaviour, serotonin and dopamine levels in daphnia magna exposed to the monoamine oxidase inhibitor deprenyl
This study assessed the effects of the monoamine oxidase (MAO) inhibitor deprenyl in Daphnia magna locomotor activity. The mechanisms of action of deprenyl were also determined by studying the relationship between behaviour, ...
PExM: polyplex expansion microscopy for cell trafficking studies
Nanomedicine is a field at the intersection of nanotechnology and medicine, promising due to its potential to revolutionize healthcare. Despite its long trajectory, there is still a long road ahead for its full development, ...

This article is based on a research devoloped during the academic year 2009-2010 by Carla Alexandra Ackermann, Anna Martínez Moles and Alba Vendrell Torres. The research was conducted under the supervision of Professor ...
Vostè i George Orwell: Sobre l'humanisme orwellià i la condició de l'home corrent
George Orwell és un dels escriptors més influents del segle XX, i les seves novel·les, des de 1984 fins a Homenatge a Catalunya, des de La rebel·lió dels animals fins a Dies a Birmània, ja són referents de la literatura ...
The role of carbon black surface activity and specific surface area in the vulcanization reaction
This paper reviews the work developed in studying how Carbon Black presence may affect the vulcanization process and the mechanisms by which CB and polymer interact, which has not been completely described in the studies ...
3D printed polymeric stent design: Mechanical testing and computational modeling
Polymer-based bioresorbable scaffolds (BRS) aim to reduce the long-term issues associated with metal stents. Yet, first-generation BRS designs experienced a significantly higher rate of clinical failures compared to permanent ...
Electrostatic potential as a reactivity scoring function in computer-assisted enzyme engineering
The high catalytic efficiency of enzymes is attained, in part, by their capacity to stabilize electrostatically the transition state of the chemical reaction. High-throughput protocols for measuring this electrostatic ...
Linking Personality Traits and Most Valued Aspects in a Job to Reduce the Gap between Students´ Expectations and Company Value Propositions
Minimizing the gap between students’ expectations and company value propositions is essential to improve the professional development of students, reduce turnover and foster organizational commitment, and so, career advisors ...
Audit firm tenure and independence: a comprehensive investigation of audit qualifications in Spain
The European Commission's Green Paper on Audit Policy has raised serious concerns about external auditor independence and also encouraged further research about the implications of long audit firm tenures. We examine the ...
Application of the NPK Method in the Crystallization Kinetics of High-Density Polyethylene
The Non-Parametric Kinetics (NPK) method, developed in 1998, by Serra, R., Sempere, J. and Nomen, R. has been used by them and other research groups to analyze the thermal behavior of a physical or chemical transformation ...
Brain energy metabolism: A roadmap for future research
Although we have learned much about how the brain fuels its functions over the last decades, there remains much still to discover in an organ that is so complex. This article lays out major gaps in our knowledge of ...
La mandra
L’eficiència, la recerca de la productivitat i la necessitat de competir sembla que ens condueixin a la proscripció de la mandra. Tanmateix, sense mandra i sense les altres passions desordenades no és possible viure una ...
High photostability in nonconventional coumarins with far-red/NIR emission through azetidinyl substitution
Replacement of electron-donating N,N-dialkyl groups with three- or four-membered cyclic amines (e.g., aziridine and azetidine, respectively) has been described as a promising approach to improve some of the drawbacks of ...
Nitrogen positional scanning in tetramines active against HIV-1 as potential CXCR4 inhibitors
The paradigm, derived from bicyclams and other cyclams, by which it is necessary to use the p-phenylene moiety as the central core in order to achieve high HIV-1 antiviral activities has been reexamined for the more flexible ...
Enzymatic Hydrolysis of Human Milk Oligosaccharides. The Molecular Mechanism of Bifidobacterium Bifidum Lacto-N-biosidase
Bifidobacterium bifidum lacto-N-biosidase (LnbB) is a critical enzyme for the degradation of human milk oligosaccharides in the gut microbiota of breast-fed infants. Guided by recent crystal structures, we unveil its ...
The influence of the trade-off between profitability and future increases in sales on cost stickiness
This study analyses cost stickiness under the dilemma between current profitability and future sales increase. When activity decreases firms are faced to keep profitability adjusting resources, while they should also ...
