The laboratory specialises in the analysis and identification of rock and soil material, as well as the fluids trapped in rocks. The laboratory manager must be contacted at the project planning stage if use of the laboratory facilities is envisaged. This ensures that correct sample collection procedures are chosen for the specific analytical processes required, and subsequently, the correct methods and procedures are chosen. It also allows the proper scheduling and resourcing of the work requested. The laboratory is housed in modern facilities, has a team highly skilled and educated staff trained to not only operate the latest analytical equipment but to provide interpretation of data. The quality of the data is assured by using standard operating procedures and quality control measures which enable the accuracy and precision of the data to be demonstrated.

A bridge to an age when craftsmanship was as important as functionality, a vintage microscope is a work of art as well as science. The First Microscopes In the late 16th century several Dutch lens makers designed devices that magnified objects, but in Galileo Galilei perfected the first device known as a microscope. His invention, a compound microscope, had a convex and a concave lens.

Later that century, Anton van Leeuwenhoek refined the microscope for biological research.

Leeuwenhoek Microscope – Designed around by a Dutchman, Antony van Leeuwenhoek, the microscope was a simple single lens device completely handmade including the screws and rivets with greater clarity and magnification than compound microscopes of its time.

A display of items drawn from the Scientific Instrument Collection of the Macleay Museum Accessories The compound microscope – what is normally thought of as a microscope – having an eyepiece and an objective separated by a tube and used for examining small objects was invented about A number of investigators made significant discoveries with compound microscopes in the late 17th century. It was not until the early decades of the 19th century that various technical problems were significantly diminished that the microscope became a valuable instrument of scientific research.

The problems were especially those of optics. Although achromatic lenses had been developed for telescopes in the mid 18th century, the small lenses used in microscopes presented difficulties of manufacture. The improvement of objectives, eyepieces and illumination between and brought the light microscope to the limits of resolution. In the latter years of the 19th century many of the micro-organisms responsible for infectious diseases were discovered.

These discoveries and consequent improvements to public health could not have occurred without the dramatic improvements to the microscope. This display looks at various accessories used with microscopes. Many of these were developed in the 19th century and contributed to the scientific use of microscopes. Optical Glass The lenses of microscopes and other optical instruments use special sorts of optical glass.

Individual lenses with spherically polished surfaces produce spherical and chromatic aberration. Lines of light passing through the lens at various distances from the centre come to a focus at different distances from the lens. Also a wedge of the lens is like a prism dispersing the different wavelengths of white light into the colours of the rainbow.

There are no pictures, minimal lay-out, no links or sorting and searching systems. This is not a web-site, it is a rough article for review by serious and knowledgeable Minolta collectors, from one to another. Not all minor variants have been included, though most are indicated in the details. If I can have a specific date for a variant, it will be separated.

In Ernst Leitz joined the institute and by was a full partner. Upon the death of Behltle, Leitz became the sole owner of the now renamed company, E Leitz, Wetzlar. Leitz continued to manufacture quality microscopes and telescopes.

In fact, I think this is a fitting moment to forumulate my thoughts, simply because Suchet has just started filming Curtain, thus initiating the final year of filming for the series, after which he will have done all the stories and portrayed the character on screen for no less than 25 years! I sincerely hope he will at least receive a new nomination once Curtain has been shown on television. He certainly deserves it. To me, David Suchet is one of the best character actors of our time.

His approach to his characters is so detailed and refined. Sigmund Freud and Robert Maxwell. If it is a character in a play, he goes back to the original words of the playwright e. Iago, Joe Keller and James Tyrone.

Through mounting evidence, however, the shift appears not only to have failed in accelerating discovery of new first-in-class medicines, but has also led to higher attrition rates of new lead molecules2. One of the most important and widely studied phenotypic responses is apoptosis; particularly in oncology research. Understanding apoptosis as it relates to a particular disease helps in understanding its pathogenesis, as well as how it can be treated.

In cancer, the normal course pursued by a cell towards death via specific stimuli is lost, leading to uncontrolled cell division. This represents a major causative factor in the development and progression of the disease3.

Bausch and Henry Lomb. Both men settled in Rochester, New York and began constructing eyeglasses before forming an official partnership and founding the Vulcanite Optical Instrument Company in to produce frames for glasses and magnifiers from hard rubber. By the late s, Bausch’s son Edward had joined the team and the company added microscopes to the growing product lineup.

Gundlach designed a full product line of microscopes and patented a variety of stands and accessories before leaving the company in Providing versatility through an almost unlimited number of positions, the KAJ microscope offers a modicum of comfort via paired eyepieces that may be adjusted to suit the observer. In addition, the Greenough-style microscope forms an erect, apparently three-dimensional image of the specimen. Each body tube is fitted with an achromatic objective, a Huygenian eyepiece, and a Porro prism.

Unlike more modern binocular microscope designs based on beamsplitters, these Greenough microscopes produce erect, three-dimensional images that are, however, inverted by degrees.
