Ziele der Lehrveranstaltung

(Bitte beachten Sie die Beschreibung in Englisch.)

Understanding the dynamics of physical, chemical and biological processes that control heat, mass and momentum transport in an organism is extremely important in physiology and bioengineering. Since transport phenomena influence both normal and pathological functions of cells and organisms, their knowledge is also fundamental to design medical devices: dialysis machines, accretion of artificial organs on scaffolds and intravenous feeding among others. In this course, the physics of biological flows for medical applications is explored. Particular attention is paid both to develop physical intuition, and to use appropriate mathematical modelling skills. The course will cover basic concepts of fluid mechanics, transport of heat, mass and momentum and biochemical interactions. [Examples and problems discussed during lectures will be solved analytically and/or numerically, see Ubung].

Exams:
3 VO exam dates each semester. Each VO exam covers the entire program of the VO lectures.

The first exam for this VO will be held on January 30th, 2018!

Structure of the exam:
-) Each exam consists of 2/3 problems
-) Each problem is divided into parts (2 or 3, typically).
A score is associated to each part (the maximum cumulative score considered to calculate the final grade is 100).
You should solve each problem by applying the correct equations and by providing the required results.

 

Scores:
Your grade will be assigned as follows:
SCORE                GRADE
<50   -> (fail)          5
51-65 -> (pass)      4
66-73 -> (pass)      3
74-85 -> (pass)      2
>86 -> (pass)         1

NOTE: Depending on the overall behavior of the class, the score ranges given above might change and shift towards lower values.
For instance, if scores are all below 85  then  ranges could be as follows:
SCORE                GRADE
<45   -> (fail)          5
46-60 -> (pass)      4
61-68 -> (pass)      3
69-80 -> (pass)      2
>81 -> (pass)         1
