Global dynamics of a periodic SEIRS model with general incidence rate

We consider a family of periodic SEIRS epidemic models with a fairly general incidence rate and it is shown the basic reproduction number determines the global dynamics of the models and it is a threshold parameter for persistence. Numerical simulations are per- formed to estimate the basic reproduction number and illustrate our analytical findings, using a nonlinear incidence rate

El navío de plata de la Virgen del Rocío

El ambicioso programa de investigación del proyecto Andalucía Barroca 2007 ha implicado la restauración y preservación de gran parte del Patrimonio Artístico Andaluz de este periodo. Una de las restauraciones llevadas a cabo ha sido el barco de plata conservado en el santuario de Nuestra Señora del Rocío de Almonte. Tradicionalmente se había atribuido al orfebre francés del siglo XVII Claude Ballin, aunque, tras la restauración se ha comprobado que realmente se trataba de una obra de principios del siglo XX, realizada en el taller de platería de Ludwig Neresheimer en Hanau, Alemania

Mexican Situation

In México over 23 million people cannot afford the basket of basic goods; the wealthiest 1% of the population gets 21% of the nation’s total income. We are the country of the OECD, in which salaried workers work more hours per year, while the lowest wages are paid. Corruption is the second most important problem at the country (70%), right after insecurity (80.9%). The military presence is part of Mexico's new normality. Impunity has been the cause of the increase of all types of crimes, especially the most violent ones, only around 1 to 2 per cent of crimes, including homicides, currently lead to conviction in México. There have been more than 94,000 homicides (intentional and non-intentional) since the current administration took office from 2013, through September 2015, and the prevalence of the practice of torture and disappearances are generalized. The numbers on the discovery of clandestine graves realize a general scenario of high decomposition. 3,892 women were victims of murder by virtue of their gender only between January 2012 and December 2013. In 2013, the Federal Government received 176 recommendations at the second cycle of the Universal Periodic Review (UPR) of the UN Human Rights Council. Megaprojects affect health, feeding and security of people while the harassment of national and transnational companies supported by the government appropriate the natural resources and energy, with the lowest cost and the highest profit. Water has been privatized and commercialized in multiple ways and situations. The main source of air pollution are vehicles and industry emissions that are being thrown into the atmosphere without any or not sufficient control. During the 2006-2012 time frame, the UN High Commissioner for Human Rights (OHCHR) registered 245 attacks against HR defenders, also, during the last decade, Mexico has become one of the most dangerous countries for journalism (more than 55 journalists were killed between 2010 and 2015).ITES
