NEURONAVIGATION AND STEREOTAXY – HIGH TECH IN MODERN NEUROSURGERY

January 2006 · Jurnalul de Chirurgie

Image-guided neuronavigation utilizes the principle of stereotaxis. The brain is considered as a geometric volume, which can be divided by three imaginary intersecting spatial planes, orthogonal to each other (horizontal, frontal and sagital) based on the Cartesian coordinate system. Measuring its distance along these three intersecting planes can specify any point within the brain. ... [Show full abstract] Neuronavigation provides a precise surgical guidance by referencing this coordinate system of the brain with a parallel coordinate system of the three-dimensional image data of the patient that is displayed on the console of the computer-workstation so that the medical images become point-to-point maps of the corresponding actual locations within the brain. Neuronavigation and stereotaxy provide intraoperative orientation to the surgeon, help in planning a precise surgical approach to the targeted lesion, define the surrounding neurovascular structures and allow avoiding the eloquent areas of the brain during surgery. This article reviews the role and the current applications of neuronavigation and stereotaxy. Progressive advances in technology will improve the cost-benefit ratio and the user-friendliness of the system and in the near future it may help to realize the aim of complete cytoreductive surgery with minimal morbidity. However, at the present state of knowledge, the benefits of neuronavigation only compliment the experience and knowledge of neuroanatomy of the surgeon and cannot act as a substitute for it

J. Wienen

Multistage plunger lift can be an economical alternative to pumping units under certain conditions as an innovative application of a mature technology. It is ideal for wells in which natural depletion has fallen below critical flow rate or for wells with high accumulations of solids such as sand, salt, coal fines, paraffin, and scale. The multistage tool is placed by wireline roughly 40% to 70% ... [Show full abstract] of the way down the tubing above a plunger lift system installation, typically comprised of a bottomhole bumper spring with a plunger above it. A second plunger is set on top of the tool. The system operates like a conventional plunger lift system. During the first cycle, the lower plunger carries fluids up the tubing and delivers them to the multistage tool. During the next sales cycle, the upper plunger delivers fluids to the surface, while the lower plunger delivers more fluids to the tool. The plungers work in tandem in subsequent cycles. In this way, the multistage tool acts like an intermediary standing valve.

Cool tech tools for lower tech teachers: 20 tactics for every classroom

January 2013

Make the painless transition from low tech to tech friendly!Are you struggling to embrace technology that advances at lightning speed? Or are you just plain perplexed? With new developments announced almost on a daily basis, many teachers don't know where to start. If you're one of those teachers making the transition to tech-willingly or not-Cool Tech Tools for Lower Tech Teachers is the ... [Show full abstract] resource for you. In understandable language, it describes how exactly you can use tools like webquests, wikis, social networking apps, and podcasts to enhance your lessons and keep kids engaged.William Bender and Laura Waller put technology within your reach by: Framing each tool in the context of what you need to know; Defining the tool in easy-to-understand language; there's no tech-speak; Guiding you through implementation step by step; Providing sample lesson plans to get you started; Explaining how some tools can also be used for professional developmentWith Cool Tech Tools for Lower Tech Teachers, Bender and Waller prove that technology can be painless and productive. What's more, you'll even come to love it!“This book provides a wealth of ideas for teachers who would like to use technology but do not know where to begin. Each chapter provides a lens into specific categories of use and associated websites.”—Bena Kallick, Educational Consultant“This book is an excellent resource for both new and experienced educators looking to make the most of Web 2.0 resources for teaching and learning. It can be used individually, but I think it would be most beneficial (and fun!) to use in small groups of educators as they support and surprise one another with their explorations and discoveries.”—Chris Toy, Educational Consultant, Learning Capacity UnlimitedGraduate School Instructor, University of Southern Maine
