作者： Arzu Akbulut Waseem Razzaq Filiz Tascan Department of Mathematics Faculty of Arts and Science Bursa Uluda? University Math Center House no 87 Rahmanyia Colony Department of Mathematics and Computer Sciences Faculty of Arts and Science Eskisehir Osmangazi University

In this study, the exact solutions for the propagation of pulses in optical fibers are *** values are given in the model used, and two nonlinear differential equations are *** equations are reduced to ordinary differential equations with the help of wave transformations. Then, the obtained differential equations are solved by two different methods,namely the modified simplest equation and the modified Kudryashov procedures. The solutions are given by hyperbolic, trigonometric and rational functions and the results are useful for optics,engineering and other related areas. Finally three-dimensional, contour and two-dimensional shapes are given for some solutions. These figures are important for understanding the motion of the wave. The given methods are applied to the equations for the first time. To the best of the authors' knowledge, these results are new and have not been obtained in the literature. The results are useful for applied mathematics, physics and other related areas.

Rainfall Dynamics and Landslides in Urban Areas of Gabon: The Case of Libreville-Est (Gabon)

引用

Journal of Geoscience and Environment Protection 2024年第8期12卷 239-264页

作者： Jospin Lewis Backita Moussounda André Géraud Le Brun Bivegue-Bivegue Fern Lièle Mboumbou Makanga Jean Damien Maloba Makanga Department of Environmental and Marine Geographic Sciences Faculty of Arts and Humanities Omar Bongo University Laboratory of Spatial Analysis and Tropical Environments Libreville Gabon

Due to its abundant rainfall, the city of Libreville, which concentrates more than half of Gabon’s population, is frequently confronted with the impacts of natural disasters such as floods and landslides. This study attempts to identify the complex relationships between the dynamics of land use and the role of rainfall in the occurrence of landslides. On the one hand, it uses statistics on landslides compiled from information taken from general news bulletins and, on the other, daily rainfall data obtained from the National Meteorological Department. The study revealed that the Libreville East sector, dominated by Mount Nkol Ogoum, one of Libreville’s most prominent landforms, is affected by a land-use dynamic in which human settlement has been progressing for some thirty years, to the detriment of the original vegetation which, among other things, helped to stabilise the soil on the hillsides and the marshy areas at the foot of the slopes. The result is not only an uncontrolled occupation of the land, but also a major landslide every two years in this part of the city, causing significant loss of life and property. However, an analysis of the time series shows little rainfall variability, marked in particular by a predominance of negative anomalies, and the occurrence of a few exceptional daily rainfall peaks. Similarly, the period from 20 October to 20 November, which receives the most rainfall, also appears to be the most conducive to landslides.
