Dave Allen, productivity consultant and author of Getting Things Done, talks about "mind mapping"—a shift in the way we use computers that will free our mind allowing us to have ideas we've never had before. He says that just like word processing and spreadsheets once created a paradigm shift in...
INTRODUCTION In this research examines the operational effectiveness of a Ranque-Hilsch vortex tube being used to cool tool tip during machining. The Ranque-Hilsch vortex effect was discovered in the early 1930s when it caused considerable excitement, as it demonstrated that it was possible to produce hot and cold...
INTRODUCTION Recently, Photoacoustic spectroscopy PAS found important applications in research and analysis of inorganic, organic and biological solids and semisolid. It is a non-destructive technique that is applicable to almost all types of samples. It offers a minimal sample preparation and has the ability to look at opaque...
INTRODUCTION The aim of the study was to draw up as complete as possible a representation of the geologic, hydrogeological and vulnerability status of the groundwater resources associated with the site of the EUREX nuclear processing plant in Saluggia. This representation has enabled us to describe the present...
INTRODUCTION Many thousands of impressive space structures have been built all over the world for covering sport stadiums, gymnasiums, leisure centers, aircraft hangars, railway stations and many other purposes. A number of these structures have spans of well over 200m. Due to their three dimensional action, space structures...
INTRODUCTION Most urban areas nowadays experience severe traffic jams on street networks. As the traffic congestion spreads, there is a need to apply intelligent algorithms to diminish the waste of time, air pollution, and so on. Therefore, a traffic control system seeks to minimize the delay experienced by...
INTRODUCTION The energy expended to plastically deform materials in manufacturing processes such as metal-forming processes is converted almost entirely into heat. This energy increases the temperature of the formed component and the tools while some of it is dissipated to the environment. The heat transfer to the component...
INTRODUCTION Though standard DWT is a powerful tool for analysis and processing of many real-world signals and images, it suffers from three major disadvantages, Shift- sensitivity, Poor directionality and Lack of phase information. These disadvantages severely restrict its scope for certain signal and image processing applications (1). ...
INTRODUCTION The finite element method FEM has been the most frequently used numerical method in engineering during the three past decades. It has been used in most fields of applied sciences such as computational solid mechanics (1), (2), and (3) and so on. Mesh-based methods are not well...
The shotgun is deeply woven into American firearms traditions. It has often been used by civilians as a hunting and gathering device and, if required, it crossed over into a personal defense tool as well. No segment of our society has warmed up to and used the shotgun as well...
[ILLUSTRATION OMITTED] My first Colt Single Action .45 Colt was one of the first 7-1/2" 2nd Generations out of the factory. I bought a Lyman No. 310 Tool, a single cavity Lyman No. 454424 Keith bullet mold and I was in business. I cast bullets on my mother's...
From Iosso Products Cleaning an AR-15 has never been an easy task. There were no brushes that fit correctly for complete cleaning ... until now. Wrapping a patch around a brush to make it fit and using tools to scrape away the fouling is not foolproof. A new...
A camera? In a gunzine? What's this all about, then? It's about quality, something you Handgunner readers demand in your guns and accessories. And the funny thing is this is one accessory we just about all have, but know less about than even the most basic gun stuff. Right? A...
[ILLUSTRATION OMITTED] For a while there, it was quiet. Most of us had a multi-tool stashed in our glove box but forgot it was there. Our old Boy Scout and Swiss Army knives had long since been relegated to the back of a dresser drawer collecting sock lint....
Don't you hate that "tink" sound screws make when the head twists off? Then you re left trying to figure out how to get the threaded screw shaft out of the hole in the receiver so you can mount he scope for your hunt--which is at 3:00 tomorrow morning? I...
I don't know that everyone needs a semiauto handgun to defend themselves. Recently, had someone comment about me and that my use of revolvers "Was archaic, and to use one was stupid, and anyone who used one was stupid." This bright light was using a code name in a chat...
The Brownells catalog is one of my favorite books. It contains every imaginable tool and accessory for the professional gunsmith, but what really interests me are the thousands of firearms accessories and components, items to make good guns better. The Brownells people won't tolerate junk. If a product isn't high...
[ILLUSTRATION OMITTED] In keeping with the long-standing pattern among service rifles adaptable to recreational use, the AR rifles have become a mainstay among civilian shooters. Current trends in the morphology of the arms take them several steps beyond the military application into the realm of both general and...
From MTM The new Case-Card Shooting Range Box RBMC offers a great new way to transport and store rifle cleaning kits. Sporting a toolbox top and cleaning-station base, the RBMC utilizes a 2-piece design for compact transport and convenient use once you get there. The tool section offers...
INTRODUCTION With the advent of more powerful computers, now mathematical models are increasingly accepted as design and optimization tools for engine development. To accepting a mathematical tool for engine design, it is necessary to validate the model results by experimentation. Developments in engine simulation technology have...
