Általános információk

Compulsory subject 1st year 1st semester

1 hour lecture/week + 3 hours practice/week

credit: 4

Lecturer: Dr. Károly Liliom (karoly.liliom.mta@gmail.com)

Tutor: Dr. Dániel Sándor Veres (daniel.s.veres@gmail.com)

Condition for signature: participation on at least 75 % of the practices. The lab reports should be uploaded to the given website at the end of practice.

REQUIREMENTS
Participation in the practical lessons is compulsory. No more than three absences from practices are allowed for any reason, otherwise the semester will not be credited. The missed measurements should be done with another group during the 4 weeks cycle of laboratory practices if possible. (One should ask for the agreement of the teacher of own group and the other group.)

Students must write a lab. report for each measurement in excel. The file to be filled can be downloaded from the homepage of the Department.

The students should prepare for the measurement by reading the related chapter of the laboratory manual.

All the measurements (even if it was cancelled for the given group for any reasons) can be asked during the semifinal or final exam.

Rules for lab reports :

1.      Every lab report is considered as a written test, where three types of grades can be given: „Accepted” „Correction needed” or „Not accepted” .

2.      The lab. report should be done by filling the excel sheet downloaded from the homepage of the department.

3.      The processing of data can be accepted only if it is based on the data measured by the student.

4.      Only the tasks listed in the homepage are required for a certain measurement. The lab report must be uploaded during the lab.

5.      The teacher will show, what is the mistake or missing part in the lab report, but NO re-upload of the lab report is allowed.

 

A Kowledge test will be organized in Moodle, which will be done on thew 10th week of the semester (during 10-14 Nov), at the beginning of the practical. The formula collection and a calculator can be used. Questions will be from the topics of the previous 8 practicals. Additionally, a few exam-related simple calculations and evaluations of laboratory practices will be included. There is no minimum of points to achieve.

Exam discounts can be obtained based on the test result: those who score at least 75% are exempted from the written moodle test on the exam. Students who score at least 85% are exempted from the written moodle test and the two practical question, should answer only the two theoretical questions.


Exams  (ED)
The exam consists of written and oral parts. First, a Moodle test should be done. The Moodle test can be practiced with the exam dataset in Moodle system. During the oral exam, first 2 practical, then 2 theoretical questions will be drawn randomly from the topic list.

Formula collection can be used on the exams. It can be downloaded here: Formula Collection

We call the attention that we do not give permission to take  Biophysics II. without passing Biophysics I.

Every student may ask for a permission only once to take a class even if the necessary prerequisits are not satisfied.

A tantárgy feladata az orvosképzés céljainak megvalósításában

Our teaching program is evolving continuously. Focused on the general objective of meeting the requirements of the medical curriculum, the courses are also intended to provide specific medical biophysics training.
Todays students will be the physicians of the oncoming decades. In selecting and highlighting topics of study, the first viewpoint is scientific foresight: the knowledge should be conveyed which must be pertinent to ensure first-class professional competence while keeping abreast of the most recent development in the field of study. Our aim is not only the teaching of a specific body of knowledge but also the development of the exact scientific method and concrete problem-solving abilities.

Everybody should present an ID card at the exam. In the absence of ID card the exam cannot be started. We call your attention, that there is no possibility to increase the number of exam days or places during the exam period.

The exam consists of written and oral parts. First, a Moodle test should be done. The Moodle test can be practiced with the exam dataset in the Moodle system. During the oral exam, first 2 practical, then 2 theoretical questions will be drawn randomly from the topic list.
