Effect of Polymer Crosslinking on Drug Release Kinetics
Abstract: In order to improve treatment effectiveness and minimise adverse effects, polymer-based drug delivery systems are often used to produce regulated and sustained drug release. Polymer crosslinking, which alters the structural, mechanical, and degrading characteristics of the polymer matrix, is one of the key elements affecting drug release kinetics. The porosity, swelling behaviour, and rate of degradation of the polymer are all impacted by the crosslinking process, which may be accomplished …

Assessing of Forest Structure Using Earth Observation Data: A Case Study in Munessa Forest, Oromia Region, Ethiopia
Abstract: Understanding forest structure is crucial for estimating carbon emissions associated with forests, assessing forest degradation, and evaluating the success of forest restoration efforts. However, forest structure quantification is limited to the area of interest without considering the whole forest coverage. Forest structure may be easily assessed over a wide area using data from remote sensing. Thus, by combining ground observation with satellite-based light detection and ranging (LiDAR) and Sentinel 2 …
