Rheometric Apparatus

Golgi's apparatus

Golgi reported an " internal reticular apparatus " in neurons — a structure now known as the Golgi apparatus. Although this is by far his best-remembered work, Golgi made many other important scientific discoveries in his lifetime (1843–1926), and in 1906 shared the Nobel prize for Physiology or Medicine with Santiago Ramón y Cajal for their studies on the structure of the nervous system. As we...

Performance Evaluation of Different Rheometric Shearing Techniques to Disperse Concentrated Cement Suspension

Build-up of cement-based suspensions is a complex phenomenon affected by the mixture concentration and testing parameters as well as the shear history. Accurate measurements of build-up rely on the efficiency of the applied pre-shear regime to achieve an initial defined and dispersed structure to eliminate the shear history. This can therefore enable understanding mechanisms of build-up and qua...

Dynamics of cytochrome bf complex of photosynthesis apparatus

Photosynthesis is a process under which, the radiative energy is converted into the chemical one. Compared to the man-made devices, the photosynthesis apparatus is much more efficient. This high efficiency comes from its elaborate structure, very fast transition rates and a complex electron and proton transfer chain among the subunits of the apparatus. Its main subunits (Photosystem I (PSI), bf...

Dosimetry of Occupational Radiation around Panoramic X-ray Apparatus

Background: Panoramic imaging is one of the most common imaging methods in dentistry. Regarding the side-effects of ionizing radiation, it is necessary to survey different aspects and details of panoramic imaging. In this study, we compared the absorbed x-ray dose around two panoramic x-ray units: PM 2002 CC Proline (Planmeca, Helsinki, Finland) and Cranex Tome (Soredex, Helsinki, Finland).<br ...
