An empirical analysis of the curvilinear relationship between slack and firm performance
(Springer Verlag, 2018-12)
This study performs an in-depth analysis of the curvilinear relationship between slack and future firm performance. Using a sample of US firms, we analyze the influence of three indicators of absorbed ...
Carminic acid linked to silica nanoparticles as pigment/antioxidant bifunctional excipient for pharmaceutical emulsions
(MDPI, 2020-04)
The incorporation of pigments and natural polyphenols into inorganic matrices, resulting in a hybrid material that improves the resistance and chemical stability of the pigments and the antioxidant ...
Análisis simultáneo de aflatoxinas y ocratoxina A en compost por HPLC-MS
(Asociación de Químicos e Ingenieros del Instituto Químico de Sarrià, 2010-03)
Las aflatoxinas y ocratoxina A son las micotoxinas más estudiadas debido a su elevada toxicidad y amplia distribución. En este trabajo se describe un método de análisis simultáneo de las aflatoxinas ...
Ball-burnishing effect on deep residual stress on AISI 1038 and AA2017-T4
(Taylor and Francis, 2017-05)
Ball-burnishing induces compressive residual stresses on treated materials by the effect of plastic deformation. The result is an increase in the fatigue life of the treated part, retarding the initiation ...
Inquiry based mathematics education and the development of learning trajectories
(University of Debrecen, 2020)
This article is based on the panel on inquiry based mathematics education and the development of learning trajectories held at the VARGA 100 Conference. After an introduction presenting the theme and ...
Zwitterionic 3D-printed non-immunogenic stealth microrobots
(Wiley, 2020-08)
Microrobots offer transformative solutions for non-invasive medical interventions due to their small size and untethered operation inside the human body. However, they must face the immune system as a ...
Octanol-water partition coefficients of highly hydrophobic photodynamic therapy drugs: a computational study
(Asociación de Químicos e Ingenieros del Instituto Químico de Sarrià, 2013-10)
Photodynamic therapy is a novel treatment for solid tumors based on the selective induction of cell death by the generation of cytotoxic reactive oxygen species within neoplastic tissues. Oxygen ...
Singlet oxygen in antimicrobial photodynamic therapy: photosensitizer-dependent production and decay in E. coli
(MDPI, 2013-02)
Several families of photosensitizers are currently being scrutinized for antimicrobial photodynamic therapy applications. Differences in physical and photochemical properties can lead to different ...
Role of amino terminal substitutions in the pharmacological, rewarding and psychostimulant profiles of novel synthetic cathinones
(Elsevier, 2021-03-15)
The emergence of new synthetic cathinones continues to be a matter of public health concern. In fact, they are quickly replaced by new structurally related alternatives. The main goal of the present ...
Reference epistemological model: what form and function in school institutions?
(Pontifícia Universidade Católica de São Paulo, 2020)
Many teaching problems are related with the lack in the school institutions of epistemological tools to design, manage and evaluate study processes. We propose to include within these tools the ...
