Modeling Bioclogging Effects in Constructed Wetlands for Wastewater Treatment new

R. Samso[1], N. Forquet[2], P. Molle[2], J. Garcia[1]
[1]Department of Hydraulic, Maritime and Environmental Engineering, Universitat Politècnica de Catalunya-BarcelonaTech, Barcelona, Spain
[2]IRSTEA, Freshwater Systems, Ecology and Pollution Research Unit, Villeurbanne, France

Horizontal-Flow Constructed Wetlands (HFCWs) are a particular type of biofilter, and as such they rely mostly on the activity of bacterial communities to treat wastewater. Bacterial growth in HFCWs induces dramatic changes in its hydraulic and hydrodynamic behaviour (bioclogging), which ... Read More

Fresh Produce Safety During Hydrocooling: An Engineering Model new

A. Warning[1], A. K. Datta[1]
[1]Department of Biological & Environmental Engineering, Cornell University, Ithaca, NY, USA

Hydrocooling is the process by which warm produce is chilled with water. The chilling of warm produce generates a negative pressure differential between the produce (warm) and (cold) water due to the condensation of water vapor inside the produce which forms a vacuum and can pull in ... Read More

Virtual Modeling of Thermo-Physiological Comfort in Clothing

P. Van Ransbeeck [1], R. Benoot [1], B. Van Der Smissen [1]
[1] University College Ghent, Faculty of Science and Nature, Department of Mechatronics, Belgium

This publication aims to investigate conjugate heat and mass transfer around a clothed virtual manikin. This research can be performed at different scales: (1) at material scale where a piece of textile is investigated in 1D or 2D space or (2) at system level where a clothed cylindrical ... Read More

Fluid Flow Behavior in Steady and Transient Force Medical Injection Systems

E. Gutierrez-Miravete [1], T. Langley [2],
[1] Rensselaer Polytechnic Institute - Hartford, Hartford, CT, USA
[2] Rensselaer Polytechnic Institute, Troy, NY, USA

Syringes were first conceptualized in 1650, but were invented in 1853 by Dr. Alexander Wood. As of 2011, nearly 8 billion syringes are used each year in the United States for medical purposes (not including veterinary services). These syringes are used for diseases like diabetes, ... Read More

Numerical Validation of the Efficiency of Dual-Frequency Radiofrequency Ablation

A. Candeo[1] and F. Dughiero[1]
[1]Department Electrical Engineering, University of Padova, Padova, Italy

Radiofrequency Ablation (RFA) represents a valid alternative for treating liver metastases in medically complicated patients. Conventional devices currently operate at 500 kHz, due to good conducting properties of tissues. However, the use of lower frequencies (i.e. 20 kHz) has been ... Read More

Simulation of a Magnetic Induction Method for Determining Passive Electrical Property Changes of Human Trunk Due to Vital Activities

H. Mahdavi[1], J. Rosell Ferrer[1]
[1]Universitat Politècnica de Catalunya, Barcelona, Spain

The human body consists of many different types of tissues each with specific passive electrical properties. Vital activities lead to a characteristic change of these properties and geometrical changes. Magnetic induction is a non-contact method which can be used to determine these ... Read More

Optimizing Performance of Equipment for Thermostimulation of Muscle Tissue using COMSOL Multiphysics

J. Kocbach[1], K. Folgerø[1], L. Mohn[2], O. Brix[3]
[1]Christian Michelsen Research, Bergen, Norway
[2]Luzmon Norway, Bergen, Norway
[3]Michelsen Medical, Bergen, Norway

The design challenge for thermostimulation equipment is to get a combination of high electric field strength and high temperature within the muscle tissue without causing pain or skin burns. In the present work, COMSOL Multiphysics is used to simulate the temperature distribution and ... Read More

Hemodynamic Simulations of Implanted Multilayer Flow Modulator

A.B. Boubker[1], A. Restante[1]
[1]CARDIATIS, Isnes, Belgium

Ruptured aortic aneurysm is one of the commonest cause of mortality in developed countries. To avoid it interventional repair is an effective treatment. In the recent years the development of new therapies, such as stent implantations, allows to perform this treatment more and more ... Read More

Simulations of Lateral Flow and Vertical Flow Microarray Assays for Point of Care Diagnostics new

G. E. Svedberg[1], L. Lama[1], J. Gantelius[1]
[1]Science for Life Laboratory, Stockholm, Sweden

Paper based lateral flow assays are widely used as point of care devices for disease diagnostics due to their low cost, short run time and ease of use. Binder molecules specific for certain molecular biomarkers of interest are typically deposited as dots or lines on paper strips, ... Read More

FEM Simulation of Magnetically Triggered Hydrogel Micro Particles as Advanced Drug Carriers new

O. Yassine[1], M. Kavaldzhiev[1], J. Kosel[1], Q. Li[1], A. Alfadhel[1], A. Zaher[1]
[1]Electrical Engineering Division, CEMSE Group, King Abdullah University of Science and Technology, Thuwal, Saudi Arabia

Thermally responsive microgel Poly (N-isopropylacrylamide), particles are embedded with iron oxide nanobeads creating magneto-thermally responsive microparticles (MTMs). The magnetic losses in the nanobeads activate the PNIPAM by heating it up to its lower critical solution temperature ... Read More
