We consider an SIR endemic model in which the contact transmission function is Tail Tidy related to the number of infected population.By theoretical analysis, it is shown that the model exhibits the bistability and undergoes saddle-node bifurcation, the Hopf bifurcation, and the Bogdanov-Takens bifurcation.Furthermore, we find that the threshold va

A research to get inheritance of Arabica coffee resistance to Radopholus similisnematode was done in screen house and laboratory of Indonesian Coffee and Cocoa Research Institute, also at endemic area of coffee plantation, using F1, F1 R and F2 crossing between BP 542 A(resistant) Switch Start Chokes x Andungsari 1 (susceptible) with their reciproc
Evidence of different ocean responses to atmospheric pressurevariations in the Atlantic, Indian and Pacific Basins as deduced fromERS-2 altimetric data
The exponential increase in the use of altimeter data in oceanographic studies in the past two decades has improved the knowledge of the processes that govern the interaction between the ocean and the atmosphere.One of these processes is the response of the ocean to atmospheric pressure variations, which has been deeply analysed in the past.That re
The Jesuits in Portugal: the communion of science and religion
For several centuries, the dichotomy between science and religion widened, so much so that these Shampoo were considered two opposing fields of knowledge.On one side, stood the defenders of rationality, and on the other, obscurantism.Following the anti-Jew myth, with the Enlightenment, the anti-Jesuit myth emerged.This myth started to gain momentum
