Multi-material fused filament fabrication: an expedited methodology to assess t...

The impact of 3D printing and how it is present in everyday life is unquestionable. Provided with almost total freedom of design and a vast list of materials, 3D printing has attracted enormous interest, being the fused filament fabrication (FFF) technique one of the main drivers. Given the vast range of compatible materials, FFF potential is being further developed towards multi-material prints. Still, one of ...

O impacto organizacional e social das tecnologias emergentes: o caso das blockc...

The results of a questionnaire that seeks to ascertain the organizational and social impact of the blockchain technology in Portugal are presented. It is structured according to the model proposed by the authors, which presents the following 3 parts: characterization of the respondents' profile, factors of knowledge and of use of the blockchain technology, and expectations and impact of this technology in Portu...

Two boson stars in equilibrium

We construct and explore the solution space of two nonspinning, miniboson stars in equilibrium, in fully nonlinear general relativity (GR), minimally coupled to a free, massive, complex scalar field. The equilibrium is due to the balance between the (long range) gravitational attraction and the (short-range) scalar mediated repulsion, the latter enabled by a π relative phase. Gravity is mandatory; it is shown n...

Effects of LED lighting on Nannochloropsis oceanica grown in outdoor raceway ponds

Growth in most microalgal mass cultivation systems is light-limited, particularly in raceway ponds (RWP) where the light path is higher. Artificial lighting can be a promising solution to diminishing dark zones and enhance microalgal productivity. Therefore, our goal was to prevent the cell shift from photosynthesis to a respiration-only stage by resorting to LED illumination. Nannochloropsis oceanica cultures ...

Dietary Acid Load: A Novel Nutritional Target in Overweight/Obese Children with...

<jats:p>Obesity has been repeatedly linked to asthma, and several potential mechanisms have been proposed in the etiologies of the obese-asthma phenotype. Considering that lungs play an important role in systemic pH and acidbase regulation, are a key organ in asthma development, and that nutritional inadequacy of several nutrients and high dietary acid load can affect airway inflammation and reactivity, we aime...
