Coursework ?f „Bi?physics” includes biophysics of human and elements of medical physics. In general biophysics is an interdisciplinary branch of science which develops at the border of physics, chemistry, biology and medical sciences. It employs physical methods and techniques to study phenomena taking place in living organisms at all levels of their organization, from the micro to the macro scale, from molecules to cells and whole organisms. Medical physics means application of physical phenomena and physical methods and techniques (e.g. ultrasounds, light, laser, ionizing radiation, nuclear resonance) in medical diagnosis and therapy.

Rules and regulations
Information about the course
“Bi?physics” pr?gram is realized in the first semester of first year. The coursework of Biophysics includes 30 hours of lectures and 45 hours of laboratory exercises. Laboratory exercises are realized in Student Laboratory in Biophysics Department. The labs and lectures are prepared in a week cycle. Students have to pass biophysical laboratory exercises i.e. perform nine practical laboratory exercises and pass three test (after performing each three practice exercises). Biophysics is ended with the Final Exam in writing form. Exam covers the topics of lectures and exercises.

REGULATIONS OF STUDENTS LABORATORY IN THE BIOPHYSICS DEPARTMENT
I. The aims of the laboratory.
The aim of the biophysics laboratory is to introduce students to the commonly encountered
measuring apparatus, development of a scientific understanding of biological phenomena,
logical observations and facts recollection as well as the development of a critical view on the
outcomes of measurements.
Students realize above aims by individually conducting experiments.
II. The course of classes in the laboratory.
1. The experiments in the laboratory are performed according to the course of study. 2. Classes are forerun with an introduction, during which regulations, experiment assignment,
methods of data collection and processing are discussed. Safety training is carried out. 3. Experiments curriculum, theoretical knowledge requirements and literature suggestions are on
the board of announcements in the department of biophysics.
4. A student is expected to realize 9 experiments, take a test and come up with measurement
results and write lab report.
5. Every experiment is realized by two students simultaneously.
6. To every experiment a student has to prepare theoretical knowledge. Preparation will be tested
by the tutor during the experiment.
Attention! In case of unfamiliarity with the material needed for safe and secure performance of the
given experiment, the tutor has the right to abort the undertaken experiment. 7. The student must complete and pass each exercise performed. The complete passing of an
experiment is determined by the tutor on the bases of tests, work during class and compiled
In the case of wrong experiment or errors in report, tutor inform about the need of repeat of
experiment or its part or correction of lab report. Every correction has to be realized in the
laboratory. It is not allowed to take experimental cards to home!
8. A complete experiment in the lab covers:
Entrance to the lab: a student is obliged to show his tutor a written compilation of the
theoretical part and to pick up his experimental card;
Carrying out the experiment i.e.
- a thorough familiarization with the instructions to the exercise undertaken.
- turning on the measuring devices, taking measurements and filling out a experimental card.
Results should be written in either pen or fountain pen (not in pencil!)
Preparing the elaboration of the results on an experimental card.
Finishing of work in the laboratory includes:
- Tidying up of workplace.
- Returning filled experimental card together with written compillation of the theory of
If student d?esn’t manage t? prepare the lab rep?rt during classes, he sh?uld rep?rt it and
return it unfinished. It can be finished in the appointed week. Student can also finish them
during next classes in the laboratory.
9. Student can only pass and conduct experiments acc?rding t? his gr?up’s schedule.
10. The longest acceptable late-coming is 15 minutes. After this time, student cannot participate in
11. Experiment conducted not individually is not treated as completed.
12. All the absences must be excused at the gr?up’s tut?r. Tut?r sets a new date f?r c?nducting
13. Conditions of getting pass the laboratory work are the following: passing all the tests, carrying
out indicated experiments and elaborating their results.
III. Order regulations.
1. All operations during setting the devices should be conducted individually. Turning on electricity
sources without having it controlled by the tutor is not allowed.
2. While carrying out experiments all safety rules must be obeyed permanently. 3. Students takes material responsibility for all the damages caused in the laboratory from his own
4. The workplace, after carrying out the experiments, should be left in its initial state. 5. Eating in the laboratory is forbidden.
6. Using mobile phones in the laboratory is forbidden.
“Bi?physics” ends with a written exam. Be admitted t? the exam is necessary t? pass the Laboratory. Those who do not pass Laboratory Excercises before Exam, are not admitted to exam and will receive an unsatisfactory grade
1. The Final Exam is performed in written form - 30 open questions. Questions cover topics of
lectures and exercises.
2. Students who failed the Final Exam are obliged to retake the test.
3. An excuse for absence should be submitted to the examiner the next day, or in justified
circumstances, within three days after the Final Exam.
4. The Final Exam will be assessed according to given marks:
(Fail) – less than 55%
(3) – 55%
(3,5) – 63 %
(4 ) – 70%
(4,5) – 80 %
(5) – 90%
