Relative Biological Effectiveness: Review of a Model
To understand why different energy doses are necessary to bring about the same biological effect by different radiations can be considered as the crucial issue of radiation biophysics. For example, the early t...

Zusammenfassung
Der Mensch besitzt eine hochentwickelte Fähigkeit, Bewegungen im dreidimensionalen Raum optisch zu erfassen und mit dieser Information nicht nur sich selbst, sondern auch wesentlich höherdynamische Systeme (wi...

Interpreting Survival Observations Using Phenomenological Models
It is generally accepted that the dose-rate dependence of the mammalian-cell survival curve reflects the modification of initial damage by cellular biochemical processes. However, these processes have not been...

The Lethal and Potentially Lethal Model — A Review and Recent Development
The Lethal and Potentially Lethal (LPL) Model [1] is a kinetic model of cell killing based on the following basic assumptions:
-
The damage caus...

The pairwise lesion interaction model
The continued observation in many laboratories of the dependence of radiation-induced exchange-type chromosome aberration yield on temporal dose distribution and on radiation quality has repeatly encouraged bi...

Formal, Empirical and Mechanistic Equations in Cellular Radiation Biology
The great complexity of the chemical and biochemical reactions which take place in cells exposed to ionizing or 254 nm ultraviolet (UV) radiations makes it necessary to develop mathematical equations to facili...

Prelude: Why and to What End Mathematical Models in Radiation Biology
There can be little doubt that radiation biology is that branch of biological sciences which can boast with the largest number of mathematical models: During the early parts — but to a large part still today —...

Problems in Theoretical Track Structure Research for Heavy Charged Particles
Heavy charged particles play an important role in radiation research related to neutron (Fig. 1) or heavy ion radiation-therapy (ion masses up to Z = 10) (2,3) or -protection (e.g. for workers in nuclear insta...

The Role of Energy Distributions of Charged Particles in the Mutagenic Radiation Action
In addition to lethal effects, mutagenic effects of ionizing radiations are investigated in many centres. A very convenient object for these studies is Escherichia coli owing to the fact that the pathways of D...

Automatische Steuerung eines Luftkissenfahrzeugs in drei Bewegungsfreiheitsgraden durch Auswertung visueller Information
Mit der Stabilisierung eines Stab/Wagen-Systems konnte in [Meissner, 82] und, darauf aufbauend, in [Wünsche, 83b] gezeigt werden, daß der im letzten Kapitel skizzierte Ansatz zur Bewegungssteuerung durch Rechn...

Saturation in Dual Radiation Action
The development of the principles of the theory of dual radiation action is reviewed and a treatment of saturation is given. Although the relationship derived cannot be evaluated in general in closed form, app...

Cluster Theory of the Effects of Ionizing Radiations
When a single heavy ion crosses a cell nucleus, it may produce DNA strand breaks and chromatin scissions wherever the ionizing track structure overlaps chromatin structures. The multiple yield of such lesions ...

DNA Double-Strand Breaks and their Relation to Cytoxicity
In previous publications we have proposed that DNA double strand breaks were the crucial lesions leading to radiation induced cell death, chromosomal aberrations and mutations, and furthermore we have argued t...

A Repair Fixation Model Based on Classical Enzyme Kinetics
Since radiation induced damage may be repaired by cells any model attempting to describe cellular radiative action in a quantitative way has this fact take into account. There is a considerable number of sugge...

Models of Cellular Radiation Action — An Overview
The fundamental concept underlying our understanding of the effects of ionizing radiation is directly related to the quantum nature of primary physical energy transfer processes. Discreteness and random distri...
