Robust mortality prediction on a recirculating aquaculture system.

Aquaculture presents itself as one of the most rapidly developing means of sustainable production of animal protein to feed ever-growing populations. Recirculating aquaculture systems offer higher control and fewer inconveniences than traditional systems, making them an attractive option for fish production. Although the sector's digitalization is in its early stages, its application should increase its rentability while conserving the environment.

Circular economy in plastic waste - Efficiency analysis of European countries.

The way plastics are currently produced, used and disposed does not capture the economic benefits of a more 'circular' approach and is dramatically harming the environment. It is relevant to determine which European countries can be considered more or less efficient in the end-of-life of plastic products processes, what the sources of the inefficiencies are, and how those less efficient countries could improve their performance towards a more circular economy. Although some countries have developed a variety of quantitative indicators, there is scarcity of adequate metrics for performance measurements.

On a class of N-dimensional anisotropic Sobolev inequalities.

In this paper, we study the smallest constant in the anisotropic Sobolev inequality of the form and the smallest constant in the inequality where with and . These constants are characterized by variational methods and scaling techniques. The techniques used here seem to have independent interests.

The origin of the LCST on the liquid-liquid equilibrium of thiophene with ionic liquids.

Mixtures of thiophene with two ionic liquids, namely, [C(4)C(1)im][SCN] and [C(4)C(1)im][NTf(2)], were chosen as prototypes of systems presenting lower critical solution temperature (LCST) and upper critical solution temperature (UCST) behavior, respectively. This distinct behavior is due to different interactions between the constituting species which are investigated here by means of experimental and computational studies. Experimentally, density measurements were conducted to assess the excess molar volumes and (1)H and (13)C NMR spectroscopies were used to obtain the corresponding nuclear chemical shifts with respect to those measured for the pure ionic liquids.

Comprehensive surgical and chemotherapy treatment for invasive bladder cancer.

Introduction: The treatment of transitional cell bladder cancer with muscular invasion remains difficult, due to the numerous patterns of biological behaviour of the disease. There is controversy regarding the application of systemic therapy in invasive bladder carcinoma and the ideal time for the indication of perioperative chemotherapy. This is an overview of systemic therapy in invasive bladder cancer.
