Los métodos de producción biotecnológicos desempeñan un papel económico muy significativo en las industrias farmacéutica, química y alimenticia. El biorreactor de burbujas aquí mostrado representa una alternativa sencilla y ...
Principle
Why are there only a few different kinds of plants in a deciduous forest? Except for having trees that are all approximately of the same height, hardly any other plants grow in a deciduous forest, except for young plants of the same type of trees. This experiment shows how the ...
Aproximando una punta aguda de silicona montada en un voladizo (cantilever) para tomar una muestra de una superficie se produce una interacción a escala atómica. El resultado es que el voladizo se curva, lo cual se detecta con láser. En modo ...
Genetically determined growth processes in plants are primarily triggered or inhibited by special phytohormones. However, external factors such as light, temperature, water, oxygen and air humidity play a decisive role in these processes. With regard to temperature, there are ...
The cell membrane controls the transport of nutrients and water into the cell, and of waste products and water out of the cell. This can take place passively, e.g. on the basis of osmotic processes (differences in concentration), as well as actively.
Benefits
Catalase is an enzyme that - in humans - is found predominantly in the liver and erythrocytes. It decomposes hydrogen peroxide, which is a toxic byproduct of cellular respiration, into water and oxygen.
The principles of relaxation processes using the MR technology are demonstrated. Experiments are executed with the MRT training device giving the opportunity to investigate some small probes in the sample chamber. Device control is done with the provided software. ...
It should be demonstrated how spatial encoding does work in the MR technology. Experiments are executed with a MRT training device giving the opportunity ton investigate some small probes in the sample chamber. Device control is done with the provided software. Investigations ...
The aim of these experiments is to show how the spin echo technique can be used to generate 2D MR images of a slice of a well-defined thickness, orientation, and size (Localized Spin Echo 2D). These parameters determine the so-called "field of view" (FOV) of the MR image. ...
