The GE – Portuguese Journal of Gastroenterology (formerly Jornal Português de Gastrenterologia), founded in 1994, is the official publication of the Sociedade Portuguesa de Gastrenterologia (Portuguese Society of Gastroenterology), Sociedade Portuguesa de Endoscopia Digestiva (Portuguese Society of Digestive Endoscopy), and Associação Portuguesa para o Estudo do Fígado (Portuguese Association for the Study of the Liver).
The journal publishes clinical and basic research articles on gastroenterology, digestive endoscopy, hepatology, and related topics. Review articles, clinical case studies, images, letters to the editor, and other articles such as recommendations or papers on gastroenterology clinical practice are also considered. Only articles written in English are accepted.
Mathematics concerned with geoscientific problems, i.e., Geomathematics, is becoming increasingly important, as first, modern high speed computers and satellite based techniques are entering more and more all geodisciplines and secondly a growing public concern about the future of our planet exists, its climate, its environment, and about an expected shortage of natural resources . Efficient strategies of protection against threats of a changing earth and the exceptional situation of getting terrestrial, airborne as well as spaceborne data of better and better quality explain the strong need of new mathematical structures, tools, and methods.GEM – The International Journal on Geomathematics publishes peer-reviewed mathematical papers that deal with (i) modelling of the system Earth (geosphere, cryosphere, hydrosphere, atmosphere, biosphere) (ii) analytic, algebraic, and operator-theoretic methods and (iii) computational and numerical analysis methods necessary for the mathematical treatment of geoscientifically relevant problems. Book reviews are welcome.
