Targeted drug delivery systems have been wildly studied in cancer therapy due to the toxicity of most of chemotherapeutic drugs. Nanoparticles can be attached to the small molecules of the drugs and serve as drug carriers to deliver the drug molecules into the area of interest. In this research, polymeric microspheres containing biodegradable poly(D, L-lactide-co-glycolide) (PLGA), magnetic ...

Mathematical optimization can be used as a computational engine to generate the best solution for a given problem in a systematic and efficient way. In the context of monolithic converter systems, the parameter estimation problem (or inverse problem) is solved using Partial Differential Equations (PDE)-based models of the physical system coupled with an optimization algorithm. These problems are ...

Windows are the thermal weakest places in the external envelop of buildings. This is true for historic windows with original single pane glazing in historic buildings. To reduce the energy consumption and to improve thermal comfort of historic buildings, replacing these windows by modern double glazed windows affects the authentic character of these buildings too much. One way to improve the ...

Within wool textile industries, a very important role is played by the so-called finishing processes, in which the textile substrate undergoes steam treatments to achieve the desired level of stabilisation and appearance. Process parameters, namely temperature and moisture content, are known only at the beginning of the process but not in the textile material being treated, where the actual ...

Microdialysis is a technique of continuous glucose monitoring in diabetic patients. In microdialysis, a saline serum is perfused into a microdialysis probe. Glucose pass from the plasmatic fluid through the porous membrane. The glucose concentration in the dialysate obtained is measured by an external analytical device. This preliminary work aimed to obtain a model to relate glucose ...

Water adsorption in highly porous materials can be used in heat transformation processes for the efficient use of energy in heat and cold production. One technology for such a thermal heat transformation is the use of water adsorption in highly porous adsorbents like zeolite. To optimize the power density of compact thin layer adsorbent beds, a one-dimensional model of the coupled heat and mass ...

A bidimensional and pseudo homogenous model was proposed for the study of mass transfer in the bioadsorption process of chromium VI in the S-layer of immobilized Bacillus sphaericus in a packed column. The implementation of such a model in COMSOL Multiphysics will be explained in detail and the final results presented. These include chromium concentration profiles along the column and its ...

Photovoltaic systems can degrade with moisture. The addition of an edge-seal containing a desiccant can reduce the amount of water reaching the interior. This report discusses the modeling of the water transport into the system to determine the amount of edge seal and desiccant required. The moving freezing front of the Stefan heat-transport problem is used to model a moving moisture ...

When rice is subjected to intense heating, it results in rapid evaporation of liquid water to vapor. As a consequence, large pressures are generated within the kernel in a span of 15s resulting in large volume changes causing the kernel to puff rapidly. Under suitable conditions, the ratio of initial volume to volume after puffing could be as high as 10. Rice puffing process is a complex ...
