Fine Structure of Millipore Filters
Millipore filters and membranes are being used with increasing frequency in biological and chemical investigation. However, the structure of these filters, as well as some of the problems associated with histological techniques involved in their use, do not appear to be widely known. Early electron microscope studies (5) of Millipore filters were restricted to replicas of surface texture and to...
متن کاملThe Use of Millipore Filters in Ultrastructural Studies of Cell Cultures and Viruses
A technique is described for embedding tissue culture cells that have been adsorbed or grown on Millipore filters. The acetone used during the embedding process rendered the filters transparent so that specific areas or cells could be chosen with the aid of the light microscope. Lymphoblastoid cells processed on the filters possessed well-defined plasma membranes and microvilli which were rarel...
متن کاملAutomatic fine tuning of cavity filters
Cavity filters are a necessary component in base stations used for telecommunication. Without these filters it would not be possible for base stations to send and receive signals at the same time. Today these cavity filters require fine tuning by humans before they can be deployed. This thesis have designed and implemented a neural network that can tune cavity filters. Different types of design...
متن کاملComparison of the new millipore HC with conventional membrane filters for the enumeration of fecal coliform bacteria.
Fecal coliform recoveries were determined for six types of membrane filters using 65 nonchlorinated water samples. Results showed that the membranes could be ranked in order of decreasing recovery as follows: Millipore HC greater than Gelman greater than Johns-Manville approximately Sartorius greater than Millipore HA greater than Schleicher & Schuell.
متن کاملFine structure of hyperbolic
The main theme of the book Fine Structures of Hyperbolic Diffeomorphisms, by Pinto, Rand and Ferreira, is the rigidity and flexibility of two-dimensional diffeomorphisms on hyperbolic basic sets and properties of invariant measures that are related to the geometry of these invariant sets. In his remarkable article [23], Smale sets the foundations of the modern theory of dynamical systems. He de...
