Hybrid biofilm reactor has become a technically as well as economically feasible option for treatment of industrial wastewater. This article presents a critical review of some basic mathematical biofilm models. Mainly focus on the development and the solution of these models. The aim is to find a reasonable and simple model of hybrid biofilm reactor under aerobic and anoxic conditions and to simulate the decontamination of petrochemical wastewater.

Trees are resources that provide multiple benefits, such as the conservation of fauna, both terrestrial and marine, a source of food and raw material, and offering protection in storms, which makes it practical to understand their behavior against different phenomena. Such understanding may be possible through process modeling. Studies confirm that mangrove forests can store more carbon than other forests, influencing the fight against global warming. Thus, a critical and systematic review was carried out regarding studies focusing on mangroves to collect information on the models that have been applied and the most influential variables highlighted by other authors. Applying a systematic search for the most relevant topics related to mangroves (basic as well as recent information), it is possible to group models and methods carried out by other authors to respond to certain behaviors presented by mangroves. Moreover, possible structuring of a mathematical model applied to a species of interest thanks to the analyzed references could provide justified information to the authorities on the importance of these forests and the benefits of their preservation and regeneration-recovery.

This paper is a mathematical model based upon the human influence on the predator-prey relationship between Red Panda and Snow Leopard, which are the major species in the mountain ecosystem. It explores if these species get extinct in a certain area due to imbalance in their interaction. First, simple model of the species is discussed with no interaction between the species. Interactive model is then introduced to simulate their population when they interact with each other. The human influence is then introduced to the interactive model to observe if the species get extinct. The data in this paper are approximated for a certain area based upon the population density and habitat of the two species. All the models are simulated in python programs using Euler's method.
