  This media article sets out to inform that the Federal Government’s New Industries Development or NIDP has decided to grant 25 agribusinesses funds for their development. Warren Truss, the Federal Minister for Agriculture, Fisheries and Forestry, announced the welcome news and stated the details himself in Brisbane. read more...


• Cells and the Light Microscope
  This text aims to help the reader understand about the compound microscope and it uses. One of its many objectives is to also distinguish the different terminology regarding microscopes, such as magnification and resolution. Also, it aims to allow the reader gain a full comprehension about the structures of the plant and animal cell as read more...


• Tiny Probe Scopes Out Infections
  Technology is truly advancing as scientists develop advanced instruments to aid in the further studies of how the human body works. Other microscopes that are advanced are the petrographic microscopes which are used to study minerals. A pair of Montana State University-Bozeman researchers, Bill Costerton and David Dickensheets envisioned developing a tiny microscope so small read more...


• Polarizing Microscopy: Functions and Uses
  Although extremely valuable as an examination and investigative tool, polarizing light microscopy is still not as utilized as other types of microscopy. It has all the functions and features of standard brightfield microscopy but it offers plenty of visual details and information that some microscopy techniques can’t always provide. read more...


• Optical Mineralogy Microscopy: Instruments and Techniques
  Optical mineralogy microscopy usually utilizes polarized light microscopes and electron microscopes as tools for the study of earth materials. Theoretically, optical mineralogy microscopy is very often a means to achieve an end and is very rarely the end itself, whether it is being used for professional or educational purposes. At its epicenter, optical read more...


• History of Petrographic Microscopes
  If you look back, petrographic microscopes surely have come a long way in order for these tools to be where they are now – and that is an optical status that is acclaimed and recognized by scientists the world over. This instrument is often used in polarizing microscopy, construction and other inventions that are related read more...


• The Geological Uses of A Petrographic Microscope
  A petrographic microscope can also be used for geological purposes. It has the ability to define what kind of geological time scale the specimen is from. It can narrow down the various eons, periods, eras and epoch and specify it to the single time frame. The scientist using the petrographic microscope must be equipped with the read more...


• How to use a Petrographic Microscope
  Focusing the Microscope
  Every time you use a microscope you must adjust the focus for your eyes. A lot of people protest about eye strain using microscopes, although complaints are usually due to incorrect adjustment. The only exceptions are people with eyes that have non parallel lines of sight. If you include this condition, or if read more...


• Getting Optic Figures
  Looking for grains that yield centered optic figures
  Grains that yield centered optic figures are Isotropic as well as opaque minerals that have no optic figures. Then, for optic axis figures on uniaxial and biaxial minerals like find grains with minimum, if possible zero, and birefringence. Then, for flash figures, uniaxial and biaxial minerals are like read more...


• Rocks
  Microscopic characteristics When dealing with new types or with rocks so fine grained that their component minerals cannot be determined with the aid of a hand lens, a petrographic microscope is used. read more...


• The Petrographic Microscope
  A petrographic microscope is used to view a series of characteristics in a mineral which imitate its properties and let us to recognize it.
  The petrographic microscope is a compound microscope which is able to work with plane polarised light, meaning that it has some peculiarities.
  This is constantly done with transmitted plane polarised light, meaning that read more...


• Polarizing Microscope
  Use and History
  The polarizing microscope is a greatly an optical measuring instrument as it is an instrument for the thorough examination of specimens. In addition to standard microscope optics, there is a polarizer in the condenser and one more mounted in a slider in the tube above the objective, either in rotatable, graduated, mounts. The read more...


• Creators of Petrographic Microscope
  Documentation of the progressive evolution in microscope design for the additional prominent makers of petrographic microscopes and accessories can be found in their trade catalogs, where distinctive features can be noted for each manufacturer. Other publications record the instruments in a variety of scientific and museum collections, providing valuable details of design and construction for read more...

• Petrographic Microscopes
  Petrology is a field of geology, which focuses on the study of rocks and the conditions by which they form. There are three branches of petrology corresponding to the three types of rocks, the igneous, metamorphic and sedimentary. The word petrology comes from a Greek word meaning rock. The word lithology once approximately synonymous with read more...


• Petrographic Microscope
  Petrographic microscope, also called a polarizing microscope, is best described as a compound transmitted light microscope to which components have been added to enable the determination of the optical properties of translucent substances. The designation of the microscope as a compound microscope indicates that it has an ocular that focuses on a virtual picture of read more...
