Project title

Numerical modelling of bacterium contact

Time of implementation 01.06.2018 - 30.11.2018.
Involved countries and institutions
  1. Lithuania, Vilnius Gediminas Technical University.
  2. Germany, Technical University of Berlin.
Aim(s) of the project In order to understand and predict various industrial processes influenced by ultrafine particles the study of bacteria (cells) which are an important representative of ultrafine objects is the way suggested here. The benefit of the proposed investigation is the ability to use the models to be derived for description of the various processes, related to ultrafine particles. In known literature, there is only a small number of models published, which describe the mechanical behaviour of adhesive cells during their deformation and sticking process. In this work, we are seeking to develop new currently unavailable interaction models. The developed models will contribute to the development/evolution of mechanical sciences and will allow for the investigation of biological object properties/characteristic behaviour for the first time. The project is thereby following an interdisciplinary approach. In Lithuania, the proposed idea of the project is new. There are no theoretical investigations ongoing of ultrafine single particles or cell mechanical behaviour during its deformation, by applying the discrete element method (DEM). Additionally, there are no physical experiments performed for this selected topic.
Target group

Direct: 2 researchers.

In this project the main activities will be performed by:

Dr. Raimondas Jasevičius

Prof. Dr.-Ing. Harald Kruggel-Emden

Both will be directly benefiting. Additionally, researchers at the involved departments are expected to benefit as the performed research is expected to function as a nucleus to trigger further research in the area. 


On the longer perspective it is expected that the research will also be included in teaching performed at both institutions. Thereby, students will benefit as the research will find its way into the taught curriculum both at Vilnius Gediminas Technical University and Technical University of Berlin.
Main activities of the project and venue(s) where the project activities will be carried out:
  1. Main activities of the project (to write manuscript, related to manuscript, where bacterium tangential interaction will be investigated. This activity involves programming, numerical experiments, manuscript writing) will be performed at the Vilnius Gediminas Technical University.
  2. Other activities will be performed at the Technical University of Berlin.
Public events in the frame of the project

November 2018, a mini-workshop is planned at Vilnius Gediminas Technical University where the obtained results will be presented.

The main speakers:

Raimondas Jasevičius: Numerical modelling of adhesive dissipative S. Aureus tangential interaction.

Harald Kruggel-Emden: Particles/cells and their interaction with a fluid.

Some material of this project will be presented by Dr. R. Jasevičius in World Congress On Applied Microbiology​. R. Jasevičius is keynote speaker and Organizing Committee Member. Title: “Numerical analysis of the adhesive interaction of bacterium and glass surface”​. Rome, Italy,   August 13-14, 2018.
