As trepanning consumes less power than solid drilling, it is BEST SELLER used for drilling larger holes. This method also has an advantage when drilling a expensive material as the solid core can be used for other purposes. 2 Features and success examples Outer thread type Multiple insert grades All thread types and geometries available For STS Uniquely designed TPMX *Flange type also type insert covers wide available upon request. application area Please contact us for Patent No. 2702061 more details.

  • Abstract Drilling Away the Sprits: a Worldwide Study of Trepanation By
    Abstract Drilling Away the Sprits: A Worldwide Study of Trepanation by Lara Frame May, 2010 Director: Holly Mathews DEPARTMENT OF Anthropology Trepanation is a worldwide phenomenon that is most often studied on a case-by-case basis, with few comparisons cross-culturally or through time and with no agreement as to why it was practiced. Earlier theories have suggested ritualistic and magico-therapeutic purposes and have proposed a higher frequency of trepanations in adult males as a result of injuries sustained in warfare and gender-specific ritual practices. A compilation of case reports and information on trepanation is, therefore, vital for a bioarchaeological study of the procedure. This research catalogues and describes 297 incidences of trepanation in the extant literature in order to present a worldwide comparison of the practice and ascertain reasons for its performance. This thesis collects and reviews all of the cases of trepanation reported in the English-language scholarly literature to look for overall patterns that might lend credence to one explanation or another and to examine temporal and geographic variation. This study is of potential significance because it establishes a baseline review of all cases that others can use to draw conclusions about the reasons for this fascinating practice worldwide or in specific localities. Four questions are answered in the Discussion section. Are more men than women trepanned because men are more likely to be involved in warfare as the literature suggests? Yes, in fact more than twice the number of males than females were trepanned. Is there any evidence to support cultural explanations or is this a residual category used for when skeletal remains show no evidence of pathology? It is difficult to determine if a procedure was done for cultural reasons, especially when there are no written records.

  • Gods of the New Millenium
    VISIT… IMPORTANT FOREW0RD Around 200,000 years ago, the hominid known as Homo erectus suddenly transformed itself into Homo Sapien with a 50 per cent increase in brain size, together with language capability and a modern anatomy. How could this have happened so suddenly after 1.2 million years of no progress at all? It is anomalies such as these that have caused considerable discomfort to highly respected evolutionary scientists such as Noam Chomsky and Roger Penrose. When state-of the-art evolutionary principles are applied to Homo sapiens, the logical conclusion is that we should not be here! The religious view of Divine Creation suffers from equal scepticism. Who can take the Garden of Eden story seriously? Science and Religion are driving round in circles in a cul-de-sac. But mankind is here, and that fact needs to be explained. The evolution of mankind is only one of the many mysteries that conventional science cannot explain. In recent years, the best seller lists have featured an increasing number of popular books which have dealt with these mysteries. One of the factors behind this trend has been the series of discoveries coming out of Egypt. The discovery of a secret doorway inside the Great Pyramid and the independent dating of the Giza Pyramids and Sphinx to the era 10500-8000 BC have captured the public’s imagination. But these historical anomalies are not just confined to Egypt. All over the world we find sites such as Stonehenge, Tiwanaku, Nazca and Baalbek that do nor fit the historical paradigm. A shadowy prehistory seems to exist as a legacy in the form of stone, maps and mythology, which our twentieth century technology has only just allowed us to recognise.

  • Brain Surgery Across the Ages: Stones to Advanced Technologies
    Brain Surgery Across the Ages: Stones to Advanced Technologies Barbara Prillaman If the human brain were so simple that we could understand it, we would be so simple that we couldn’t. -Emerson M. Pugh1 Rationale Drilling holes into skulls without anesthesia, a gentleman who appears “normal” until he removes his hat to reveal half of his head missing, gravesites of skulls with missing pieces. Now, these are stories that will invoke my students’ curiosity that may be forgotten at times in our schools’ curriculum. For me, this unit addresses two weaknesses that I feel I have. First, it is developed for my College Preparatory (CP) Psychology course that I do not believe I always give the same attention to as my Advanced Placement (AP) or Dual Enrollment courses. This brings it to the forefront of my instructional planning which is very important. By using a combination of texts – written and visual, I will be better able to capture the attention of my students that struggle with reading vast amounts of materials. Second, it has made me look in- depth at the Biological Bases Unit, that, I believe to be my weakest knowledge base. Grasso’s comment, “Studying the development and role of technology in ancient times will help us better understand and contextualize the massive and unparalleled power at our fingertips today” made me conceptualize the importance of having my students understand the historical component of brain surgery – how did it all begin (which I believe will be surprising to them), and how have our technological changes affects this type of surgery.

  • THE DEVELOPMENT of DIRECT CORE MONITORING in NUCLEAR ELECTRIC Pic
    THE DEVELOPMENT OF DIRECT CORE MONITORING IN NUCLEAR ELECTRIC pic R.F. CURTIS, S. JONES XA9642905 Remote Operation Section J. REED, A.J. WICKHAM Fuel and Core Section Nuclear Electric pic, Berkeley Technology Centre, Berkeley, Gloucestershire, United Kingdom Abstract Monitoring of graphite behaviour in Nuclear Electric Magnox and AGR reactors is necessary to support operating safety cases and to ensure that reactor operation is optimised to sustain the necessary core integrity for the economic life of the reactors. The monitoring programme combines studies of pre-characterised "installed" samples with studies on samples trepanned from within the cores and also with studies of core and channel geometry using specially designed equipment. Nuclear Electric has two trepanning machines originally designed for Magnox-reactor work which have been used for a substantial programme over many years. They have recently been upgraded to improve sampling speed, safety and versatility - the last being demonstrated by their adaptation for a recently-won contract associated with decommissioning the Windscale piles. Radiological hazards perceived when the AGR trepanning system was designed resulted in very cumbersome equipment. This has worked well but has been inconvenient in operation. The development of a smaller and improved system for deploying the equipment is now reported. Channel dimension monitoring equipment is discussed in detail with examples of data recovered from both Magnox and AGR cores. A resolution of ± 2' of arc (tilt) and ± 0.01 mm change in diameter in attainable. It is also theoretically possible to establish brick stresses by measuring geometry changes which result from trepanning. Current development work on a revolving scanning laser rangefinder which will enable the measurement of diameters to a resolution of 0.001 mm will also be discussed.
