The association of dietary NaCl with arterial hypertension has led to a reduction in the levels of this salt in cheeses. For salting, KCl has been used as a partial substitute for NaCl, which cannot be completely substituted without affecting product acceptability. In this study a sensorially adequate saline solution (NaCl/KCl) was simultaneously diffused during salting of Prato cheese in brine with agitation. The simultaneous multicomponent diffusion during the process was modeled with Fick’s s...

There is a problem with keeping culture medium completely or partially free from bacteria. The use of prokaryotic metabolic inhibitors, such as antibiotics, is suggested as an alternative solution, although such substances should not harm non-target organisms. Thus, the aim of this study was to assess the effectiveness of antibiotic treatments in inhibiting free-living and biofilm bacteria and their half-life in artificial marine environment using the copepod Acartia tonsa as bioindicador of non...

Much of our knowledge of past ocean temperatures comes from the foraminifera Mg / Ca palaeothermometer. Several nonthermal controls on foraminifera Mg incorporation have been identified, of which vital effects, salinity, and secular variation in seawater Mg / Ca are the most commonly considered. Ocean carbonate chemistry is also known to influence Mg / Ca, yet this is rarely examined as a source of uncertainty, either because (1) precise pH and [CO₃²⁻] reconstructions are s...

Fundamentally, action potentials in the squid axon are consequence of the entrance of sodium ions during the depolarization of the rising phase of the spike mediated by the outflow of potassium ions during the hyperpolarization of the falling phase. Perfect metabolic efficiency with a minimum charge needed for the change in voltage during the action potential would confine sodium entry to the rising phase and potassium efflux to the falling phase. However, because sodium channels remain open to ...

The additions of artificial structures to the landscape are usually translated into habitat loss and fragmentation, since they provide homogeneous habitats less diverse in types and number of microhabitats. Moreover, the smooth surface of artificial structures increases the degree of environmental stress (e.g. desiccation) experienced by intertidal organisms. Local biodiversity can be increased with microhabitats availability by attracting or supporting species of macrofauna and seaweeds. E.g., ...

The core discussion in this paper focuses on the apprehension of the imaginary corresponding to the social reality of the Portuguese poet Fernando Pessoa (1888-1935). Our main concern lies on its descriptive effects according to an analysis of the homoerotic images that can be grasped in Ode Marítima by Álvaro de Campos, Pessoa’s most undisciplined and impetuous heteronym. Ode Marítima was first published in 1925 in Orpheu, a magazine that gave rise to Portuguese Modernism. We believe that the i...
