Tear Film Mediators After Corneal Cross-Linking: Methodology Validation
Costa, Celso; Araújo, Mariana; Rosa, Andreia; Gil, João; Quadrado, Maria João; Tavares, Cristina; Costa, Esmeralda; Fernandes, Rosa; Costa, LígiaIntroduction: Currently, the gold-standard treatment of progressive keratoconus (KC) is corneal collagen cross-linking (CXL), in which riboflavin and ultraviolet-A radiation increase the corneal biomechanical rigidity, arresting progression. However, post-operatory results vary significantly among patients. Although it has been suggested that corneal thickness, cone location and patient’s age are important fact...
Admission severity of atrial-fibrillation-related acute ischemic stroke in pati...
Garcia, Catarina; Silva, Marcelo; Araújo, Mariana; Henriques, Mariana; Margarido, Marta; Vicente, Patrícia; Nzwalo, Hipólito; Macedo, AnaIn non-valvular-associated atrial fibrillation (AF), direct oral anticoagulants (DOAC) are as effective as vitamin K antagonists (VKA) for the prevention of acute ischemic stroke (AIS). DOAC are associated with decreased risk and severity of intracranial hemorrhage. It is unknown if different pre-admission anticoagulants impact the prognosis of AF related AIS (AF-AIS). We sought to analyze the literature to ass...
From identical S- and P-wave $p_\mathrm{T}$ spectra to maximally distinct polar...
Faccioli, Pietro; Lourenço, Carlos; Araújo, Mariana; Seixas, João; Krätschmer, Ilse; Knünz, ValentinA global analysis of ATLAS and CMS measurements reveals that, at mid-rapidity, the directly-produced $\chi_{c1}$, $\chi_{c2}$ and J/$\psi$ mesons have differential cross sections of seemingly identical shapes, when presented as a function of the mass-rescaled transverse momentum, $p_{\rm T}/M$. This identity of kinematic behaviours among S- and P-wave quarkonia is certainly not a natural expectation of non-rela...
Universal kinematic scaling as a probe of factorized long-distance effects in h...
Faccioli, Pietro; Lourenço, Carlos; Araújo, Mariana; Seixas, JoãoDimensional analysis reveals general kinematic scaling rules for the momentum, mass, and energy dependence of Drell–Yan and quarkonium cross sections. Their application to mid-rapidity LHC data provides strong experimental evidence supporting the validity of the factorization ansatz, a cornerstone of non-relativistic QCD, still lacking theoretical demonstration. Moreover, data-driven patterns emerge for the fac...
Desenvolvimento e comunicação estratégica de marcas de moda sustentável: um exe...
Araújo, Mariana; Ponte, Pedro; Mota-Ribeiro, Silvana; Broega, A. C.Um ponto importante para o sucesso de uma marca é a sua comunicação, é através dela que as marcas se tornam conhecidas do seu público, nomeadamente, as marcas de moda sustentável. Este artigo tem como objetivo fazer uma reflexão e planeamento sobre o desenvolvimento e a comunicação de marcas de moda sustentável, que neste caso, será aplicada a uma marca recém criada e concebida segundo os princípios da sustenta...
Quarkonium production at the LHC: A data-driven analysis of remarkably simple e...
Faccioli, Pietro; Lourenço, Carlos; Araújo, Mariana; Knünz, Valentin; Krätschmer, Ilse; Seixas, JoãoThe LHC quarkonium production measurements reveal a startling observation: the J/$\psi$, $\psi$(2S), $\chi_{c1,2}$ and $\Upsilon$(nS) $p_{\rm T}$-differential cross sections are compatible with one universal momentum scaling pattern. Considering also the absence of strong polarizations of directly and indirectly produced S-wave mesons, we are led to the conclusion that there is currently no evidence of a depend...
Improving productivity and standard time updating in an industrial company - A ...
Araújo, Mariana; Amaral, Gabriela; Varela, Maria Leonilde RochaToday’s marketplace imposes ever-tightening product pricing and quality requirements, shorter delivery times, and increasingly customized products. With increasing competition in today’s global market, companies are increasingly pressured to improve the performance of their production systems in order to be more competitive and improve market share. In order to try to satisfy these requirements several companie...
Mathematical and computational modelling in matlab for the study of an ORC sola...
Amaral, Gabriela; Araújo, Mariana; Varela, Maria Leonilde RochaThe main objective of this paper was to acquire the necessary thermodynamic knowledge in order to perform a thermodynamic and economic analysis of a solar ORC system of capacity of 10KW. For this, a model and computer program were developed in Matlab R2008a, version 7.6.0, which analyses the efficiency of the collector based on the gross solar radiation introduced and the efficiency of the ORC cycle against the...
Dietary inclusion of IMTA-cultivated Gracilaria vermiculophylla in rainbow trou...
Araújo, Mariana; Rema, Paulo; Sousa-Pinto, Isabel; Cunha, Luís M.; Peixoto, Maria João; Pires, Maria A.; Seixas, Fernanda; Brotas, VandaDietary inclusion of IMTA-cultivated Gracilaria vermiculophylla was evaluated in rainbow trout. Growth and feed efficiency were determined in fish fed 0 % (CTRL), 5 % (G5), and 10 % (G10) of the red seaweed for 91 days. Carotenoid concentration (skin and muscle), immunological parameters, and intestinal morphology were also evaluated. G10 group showed the lowest final body weight, with feed and protein efficien...

Valente, Luísa M. P.; Araújo, Mariana; Batista, Sónia; Peixoto, Maria J.; Sousa-Pinto, Isabel; Brotas, Vanda; Cunha, Luís M.; Rema, PauloIncreasing levels of a mixture of Ulva spp. (Ulva rigida and Ulva lactuca) produced in an integrated multitrophic aquaculture (IMTA) system were evaluated in Nile tilapia. A control diet (CTRL) was compared with two experimental isonitrogenous (36 %) and isoenergetic (20 kJ g−1) diets containing 5 % (U5) and 10 % (U10) of Ulva spp. meal. Duplicate groups of 18 fish (255 g initial body weight) were reared at 25 ...
