The 1918 influenza epidemic was an event of great social and health resonance, which caused high morbidity and mortality in the population. The rapidity in the development of symptoms, the extension to very large groups of the population and the lack of knowledge of the causative agent, were the factors that, added together, made the flu a major public health problem. The objective of this study was to review, through the Spanish written press, of the public health measures adopted as a consequence of the influenza epidemic of 1918.

A selection of the Spanish press was carried out through the Digital Newspaper Library of the National Library (HDBN) of Spain, from January 1, 1918 to December 31, 1920; and the concept “flu” was searched, selecting those units of analysis that made reference to the public health measures adopted during the flu epidemic of 1918.

The newspapers analyzed reported the public health measures adopted by the health authorities of the different countries in order to reduce the spread of the epidemic, such as the closure of schools and the postponement of the opening of the academic year, disinfection of premises, quarantines, isolation, suspension, popular celebrations, disinfection and hygiene, border control, suspension of communications by train, as well as the creation and use of different vaccines and serums to immunize the population.

The poor management of the epidemic could be one of the causes of the great impact of influenza in the first half of October 1918, as the decisions of the administration to promote public health measures were adopted with some delay.

This compound is found to crystallize in the U2Co3Si5-type orthorhombic structure. The low-field χ(T) shows a clear peak at T N = 41.5 K corresponding to an antiferromagnetic transition. The M(H) curve measured up to 70 kOe exhibits an H-linear behavior at 2 K with very small induced magnetic moments, while it shows upward curvature with increasing temperature, implying the possible presence of a metamagnetic transition in high-field region above 70 kOe. As the temperature decreases, ρ(T) increases slowly at T > T N and decreases rapidly at T less then T N, which can be understood based on a semiconductor-like narrow band gap model (or the c-f hybridization effect) and an antiferromagnetic spin-wave model, respectively. No evidence of heavy-fermion behavior or superconductivity transition is observed at temperatures as low as 0.4 K. The obtained experimental results are discussed by comparing with those reported for the isomorphic compound U2Ir3Si5 and the quasi-isomorphic compound U2Rh3Si5.We report a non-enzymatic facile method for the detection of L-cysteine (L-Cyst) using free-standing TiO2 nanotube (TNT) array-modified glassy carbon electrodes (GCEs). Self-organized, highly ordered, and vertically oriented TNT arrays were fabricated by anodization of titanium sheets in ethylene glycol-based electrolyte. Detailed electrochemical measurements were performed and it was found that modified GCE exhibited high current compared to the pristine counterpart. The high current of the modified electrode was attributed to the high surface area and enhanced electrocatalytic activities of the TNTs toward the L-Cyst oxidation. Under the optimum conditions, the modified electrode exhibited a high sensitivity of ∼1.68 µA mM-1 cm-2 with a low detection limit of ∼0.1 mM. The fabricated electrode was found to be sensitive to pH and electrolyte temperature. The real sample analysis of the proposed method showed a decent recovery toward L-Cyst addition in human blood serum. Furthermore, the density-funcational theory (DFT) analysis revealed that TNTs have greater affinity toward L-Cyst, having stronger binding distance after its adsorption. The higher negative E ads values suggested a stable and chemisorption nature. The density of states results show that the E gap of TNTs is significantly reduced after L-Cyst adsorption. The modified GCE showed excellent selectivity, enhanced stability, and fast response, which make TNTs a promising candidate for the enzyme-free detection of other biological analytes.A novel graphene nanoplatelets (GNP) bridge between two semiconductors (AgBr and graphitic carbon nitride) was created to boost photoelectrochemical performance. The heterojunction created makes the whole system a Z-scheme catalyst. For the construction of this catalyst, the syringe pump methodology was adopted and different analytical techniques were used for the confirmation of structure and morphology. High angle annular dark field (HAADF), dark field (DF), DF-4 and DF-2 techniques, using Z-contrast phenomena, confirmed the heterostructure (ABGCN) and its composition. The constructed structure showed an enhanced photoelectrochemical and catalytic property against ‘acute toxicity category-III (MM)’ and ‘category-IV (tetracycline hydrochloride (TH))’ organic pollutants. The constructed catalyst degraded the MM in 57 min and the TH in 35 min with degradation rates of 0.01489 min-1 and 0.02387 min-1, respectively, due to the accumulation of photogenerated electrons on the conduction band (CB) of g-C3N4 and photogenerated holes on the valence band (VB) of AgBr by the transformation of charges through the graphene bridge. learn more An ion trapping study also revealed that ·O2 and h+ were the active species which actively participated in the photocatalytic reaction.
