The Horror of Gas Chamber Poison Zyklon B

The Horror of Gas Chamber Poison Zyklon B Beginning in September 1941, Zyklon B, the brand name for hydrogen cyanide (HCN), was the poison used to kill at least a million people in gas chambers at Nazi concentration and death camps such as Auschwitz and Majdanek. Unlike the Nazis earlier methods of mass murder, Zyklon B, which was originally used as a common disinfectant and insecticide, proved to be an efficient and deadly murder weapon during the Holocaust. What Was Zyklon B? Zyklon B was an insecticide used in Germany before and during World War II to disinfect ships, barracks, clothing, warehouses, factories, granaries, and more. It was produced in crystal form, creating amethyst-blue pellets. Since these Zyklon B pellets turned into a highly poisonous gas (hydrocyanic or prussic acid) when exposed to air, they were stored and transported in hermetically-sealed, metal canisters. Early Attempts at Mass Killing By 1941, the Nazis had already decided and attempted to kill Jews on a mass scale, they just had to find the fastest way to accomplish their goal. After the Nazi invasion of the Soviet Union, Einsatzgruppen  (mobile killing squads) followed behind the army in order to round up and murder large numbers of Jews by mass shootings, such as at Babi Yar. It wasnt long before the Nazis decided that shooting was costly, slow, and took too large a mental toll on the killers. Gas vans were also tried as part of the Euthanasia Program and at the Chelmno Death Camp. This mode of killing used the carbon-monoxide exhaust fumes from trucks to murder Jews who were crammed into the enclosed back area. Stationary gas chambers were also created and had carbon monoxide piped in. These killings took about an hour to complete. The First Test Using Zyklon B Pellets Crematorium 1 at Auschwitz concentration camp. Ira Nowinski/Getty Images Rudolf Hà ¶ss, the commandant of Auschwitz, and Adolf Eichmann searched for a faster way to kill. They decided to try Zyklon B. On September 3, 1941, 600 Soviet prisoners of war and 250 Polish prisoners who were no longer able to work were forced into the basement of Block 11 at Auschwitz I, known as the death block, and Zyklon B was released inside. All died within minutes. Just days later, the Nazis transformed the large morgue room at Crematorium I in Auschwitz into a gas chamber and made 900 Soviet prisoners of war go inside for disinfection. Once the prisoners were crammed inside, Zyklon B pellets were released from a hole in the ceiling. Again, all died quickly. Zyklon B had proved to be a very effective, very efficient, and very cheap way to kill large numbers of people. The Gassing Process Aerial reconnaissance film of Auschwitz concentration camp, 1st August 1944.   Bettmann/Getty Images With the construction of Auschwitz II (Birkenau), Auschwitz became one of the largest killing centers of the Third Reich. As Jewish and other undesirables were brought into the camp via train, they underwent a Selektion on the ramp. Those deemed unfit for work were sent directly to the gas chambers. However, the Nazis kept this a secret and told the unsuspecting victims that they had to undress for a bath. Led to a well-camouflaged gas chamber with fake shower heads, the prisoners were trapped inside when a large door was sealed behind them. Then, an orderly, who wore a mask, opened a vent on the roof of the gas chamber and poured Zyklon B pellets down the shaft. He then closed the vent to seal the gas chamber. The Zyklon B pellets turned immediately into a deadly gas. In a panic and gasping for air, prisoners would push, shove, and climb over each other to reach the door. But there was no way out. Within five to 20 minutes (depending on the weather), all inside were dead from suffocation. After all were dead, the poisonous air was pumped out, a process that took about 15 minutes. Once it was safe to go inside, the door was opened and a special unit of prisoners, known as the Sonderkommando, hosed down the gas chamber and used hooked poles to pry the dead bodies apart. Rings were removed and gold plucked from teeth. Then the bodies were sent to the crematoria, where they would be turned into ash. Who Made Zyklon B for the Gas Chambers? Zyklon B was made by two German companies: Tesch and Stabenow of Hamburg and Degesch of Dessau. After the war, many blamed these companies for knowingly creating a poison that was used to murder over a million people.  The directors of both companies were brought to trial. Director Bruno Tesch and executive manager Karl Weinbacher (of Tesch and Stabenow) were found guilty and given the death sentence. Both were hung on May 16, 1946. Dr. Gerhard Peters, the director of Degesch, however, was found guilty only as an accessory to homicide and given a sentence of five years in prison. After several appeals, Peters was acquitted in 1955.

Information Technology in Healthcare - Essay Example As the paper highlights obtaining images of X-ray from Radiology Information System (RIS) a component of eHealth requires access to the site. An x-ray taken today can be shared and deliberated as soon as it is available electronically.  From this research it is clear that  to obtain x-ray image from PACS, a client of physician should have correct credentials for the search. Firstly, the client establishes network connection with PACS server. Second step involves preparing C-MOVE or C-GET request message through filling C-MOVE requisition, which should be matched with those in the server. The request is sent and a feedback is given in a list of DICOM attributes. From the feedback, the client extract images. Often takes approximately less than 10 minutes depending on the network strengths. The major errors encountered when getting images from EHR includes patient identification errors. These errors occur as a result of incorrect information is used to link an individual to an actio n. It causes a mismatch between patient and the care plan. Another error occurs during patient journey, and as a result repetition of images may occur. Lastly, the flow of patient identification mismatch occurs at the initial stage of data entry. When using PACs, the common errors is the hanging protocol display, which causes retrieving of images to take unnecessarily longer. Since the images are not organized by default, identification and processing of images may result in misalignment, which is a potential error.  

Jainism, Buddhism, and Hinduism Essay Example for Free

Jainism, Buddhism, and Hinduism Essay Jainism, Buddhism, and Hinduism, three of the world’s most dynamic and ancient religions developed in India around the same time. Though each borrowed from, evolved because of, or came into conflict with each other: Hinduism, Buddhism, and Jainism are more than religions, but cross-sections of an entire culture and time period. Jainism, Buddhism, and Hinduism have many a huge impact on eastern life as we know it. The interactions between humans and environment that these religions have had have been phenomenal. Jainism being the oldest of the three has 12-18 million followers(jaindharmonline.com). Jain migrated from India to other countries beginning with them migrating to Britain and British colonies. In the beginning, a number of â€Å"Gujarati† Jains migrated to coastal towns of East Africa and later moved inland, particularly to Kenya, to open businesses. The Jain community in India represents an affluent and influential minority of the population.Jains now mostly reside in north-east Africa. Buddhism, on the other hand, is the sixth largest religion by population. It has about 367 million followers and is7% of the worlds population(cia.gov). Buddhism spread along land routes of the Silk Road, it underwent profound change. There were great overland trade routes in those days and in later centuries too, that joined China even to the Mediterranean. Along these routes Buddhism spread to northwest India and beyond, along the east-west Silk Route. Hinnduisms origin is much more shrouded though, in terms of its religious development there are now two basic theories that attempt to explain how Hinduism first developed within India, and they both draw on the famous â€Å"ekam sat viprah bahudah vandanti verse† for their effectiveness. One suggests that at some time towards the end of the Indus Valley Civilization a group of nomadic people called the Aryans moved into northern India from the steppes of central Europe or even Asia Minor while the other theory suggests that Hinduism emerged out of India itself(Dasa). The beliefs for these three religions are mostly the same in essence, they were all founded on the beliefs of peace and prosperity. They are also known as â€Å"The Paths of Enlightenment†. Hinduism ,though believed by many to be a polytheistic religion, the basis of Hinduism is the belief in the unity of everything. This totality is called Brahman. The purpose of life is to realize that we are part of God and by doing so we can leave this plane of existence and rejoin with God. This enlightenment can only be achieved by going through cycles of birth, life and death known as samsara. Ones progress towards enlightenment is measured by his karma. This is the accumulation of all ones good and bad deeds and this determines the persons next reincarnation. Jainism has many similarities to Hinduism and Buddhism which developed in the same part of the world. They believe in karma and reincarnation as do Hindus, but they believe that enlightenment and liberation from this cycle can only be achieved through asceticism. In Buddhism, nirvana is freedom from the cycle of rebirth, when a being turns into a state of non-being, or Sunya, looses its identity and becomes nothing. These religions were all derived out of India which used the caste system for their government. The buildings made for these religions were all complex and amazing in nature. Buddhists temples were mostly built in natural environments, such as forests and tops of hills. Hindu temples were built in more urban environments and used red paints for most of their buildings and temples. And Jain temples were also built in more urban places and used beige and gold paints for their buildings and temples. These religions expanded in many different ways, they all originated in India, and started spreading throughout the world. The two that are most know today are Hinduism and Buddhism, Jainism still has about 16 million followers though. Buddhist temples were built along the Silk Road for prayer for the travelers. Hindu kept most of their temples inside of India unlike the Jainist that moved to northern Africa. It spread outside of Magadha starting in the Buddhas lifetime, and with the reign of the Buddhist Mauryan Emperor Asoka, spread across Nepal straight down to China and all the way to Japan and became one of the dominant religions in these parts of Asia(Chung).Hinduism is a religion] of the Indian subcontinent of India, with 80.5% of the population identifying themselves as Hindus. The vast majority of Hindus in India belong to Vaishnavite and Shaivite denominations(Thompson Patts) As part of the reaction against Hinduism during its early years, Buddhism rejected the caste system and other forms of social stratification and instead set up an essentially egalitarian society. There are only two religiously important social groups: the monks, who have dedicated their lives to full time pursuit of religious goals, and everyone else. The monks, as a group, are called the sangha(uwacadweb.uwyo.edu). When the Aryans moved into northwest India, they imposed a caste system to organize the new society created by their arrival. The Hindus then put together a hierarchy of four varnas, which later was expanded to include a fifth category. The caste system, which the Hindus followed, initially served to maintain rigid social boundaries between the invaders and the previous inhabitants. By 80 A. D. the Jains were divided into two sects. The Svetambara or white clad live mainly in northern India today(Sprunger). They are more liberal in their interpretation of Mahavirals teaching regarding nudity and allow their monks to wear a white garment. Women are also allowed in their religion and monasteries accepting the possibility that they may find salvation(Sprunger).

3d Printing Essay

3D PRINTING TECHNOLOGY Contents: 1. Introduction 2. History Of 3D Printing 3. Current 3D Printing Technologies 4. The Basic Process Of 3D Printing 5. 3D Printing VS Conventional Technologies 6. Applications 7. Conclusion Introduction 3Dimensions printing is a method of converting a virtual 3D model into a physical object. 3D printing is a category of rapid prototyping technology. 3D printers typically work by printing successive layers on top of the previous to build up a three dimensional object. The past decade has witnessed the emergence of new manufacturing technologies that build parts on a layer-by-layer basis. Using these technologies, manufacturing time for parts of virtually any complexity is reduced considerably. In other words, it is rapid. Rapid Prototyping Technologies and Rapid Manufacturing offer great potential for producing models and unique parts for manufacturing industry. A few years ago, to get some prototyping work done for a product or design you are working on, you are required to spend a lot of man-hours just to come up with the model. Those hours will be spent creating miniature parts of your design using wood and then gluing all those parts together painstakingly. Prototyping is, at the very least, time-consuming and extremely tedious. These days, however, you can take the tediousness and the time investment out of your prototyping tasks through rapid prototyping or 3d printing. 3D printing is a revolutionary method for creating 3D models with the use of inkjet technology. Many engineers have even dubbed 3D printing as the process of creating something out of nothing. Thus, the reliability of products can be increased; investment of time and money is less risky. Not everything that is thinkable today is already workable or available at a reasonable price, but this technology is fast evolving and  the better the challenges, the better for this developing process. The term Rapid prototyping (RP) refers to a class of technologies that can automatically construct physical models from Computer-Aided Design (CAD) data. It is a free form fabrication technique by which a total object of prescribed shape, dimension and finish can be directly generated from the CAD based geometrical model stored in a computer, with little human intervention. Rapid prototyping is an â€Å"additive† process, combining layers of paper, wax, or plastic to create a solid object. In contrast, most machining processes (milling, drilling, grinding, etc.) are â€Å"subtractive† processes that remove material from a solid block. RP’s additive nature allows it to create objects with complicated internal features that cannot be manufactured by other means. In addition to prototypes, RP techniques can also be used to make tooling (referred to as rapid tooling) and even production-quality parts (rapid manufacturing). For small production runs and complicated objects, rapid prototyping is often the best manufacturing process available. Of course, â€Å"rapid† is a relative term. Most prototypes require from three to seventy-two hours to build, depending on the size and complexity of the object. This may seem slow, but it is much faster than the weeks or months required to make a prototype by traditional means such as machining. These dramatic time savings allow manufacturers to bring products to market faster and more cheaply. 3D PRINTING: MAKING THE DIGITAL REAL Imagine a future in which a device connected to a computer can print a solid object. A future in which we can have tangible goods as well as intangible services delivered to our desktops or highstreet shops over the Internet. And a future in which the everyday â€Å"atomization† of virtual objects into hard reality has turned the mass pre-production and stock-holding of a wide range of goods and spare parts into no more than an historical legacy. Such a future may sound like it is being plucked from the worlds of Star Trek. However, whilst transporter devices that can instantaneously deliver us to remote locations may remain a fantasy, 3D printers capable of outputting physical objects have been in development for over two decades. What’s more, several 3D printers are already on the market. Available from companies including Fortus, 3D Systems, Solid Scape, ZCorp, and Desktop Factory, these amazing devices produce solid, 3D objects from computer data in roughly the  s ame way that 2D printers take our digital images and output hardcopy photos. History Of 3D Printing The technology for printing physical 3D objects from digital data was first developed by Charles Hull in 1984. He named the technique as Stereo lithography and obtained a patent for the technique in 1986.While Stereo lithography systems had become popular by the end of 1980s, other similar technologies such as Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS) were introduced.In 1993, Massachusetts Institute of Technology (MIT) patented another technology, named â€Å"3 Dimensional Printing techniques†, which is similar to the inkjet technology used in 2D Printers.In 1996, three major products, â€Å"Genisys† from Stratasys, â€Å"Actua 2100† from 3D Systems and â€Å"Z402† from Z Corporation were introduced.In 2005, Z Corp. launched a breakthrough product, named Spectrum Z510, whichwas the first high definition color 3D Printer in the market.Another breakthrough in 3D Printing occurred in 2006 with the initiation of an open source project , named Reprap, which was aimed at developing a self-replicating 3D printer. 3. Current 3D Printing Technologies Most commercially available rapid prototyping machines use one of six techniques. At present, trade restrictions severely limit the import/export of rapid prototyping machines, so this guide only covers systems available in the U.S. 3.1 Stereo lithography Patented in 1986, stereolithography started the rapid prototyping revolution. The technique builds three-dimensional models from liquid photosensitive polymers that solidify when exposed to ultraviolet light. As shown in the figure below, the model is built upon a platform situated just below the surface in a vat of liquid epoxy or acrylate resin. A low-power highly focused UV laser traces out the first layer, solidifying the model’s cross section while leaving excess areas liquid. Next, an elevator incrementally lowers the platform into the liquid polymer. A sweeper re-coats the solidified layer with liquid, and the laser traces the second layer atop the first. This process is repeated until the prototype is complete. Afterwards, the solid part is removed from the vat and rinsed clean of excess liquid.  Supports are broken off and the model is then placed in an ultraviolet oven for complete curing. Because it was the first technique, stereolithography is regarded as a bench mark by which other technologies are judged. Early stereolithography prototypes were fairly brittle and prone to curing-induced warpage and distortion, but recent modifications have largely corrected these problems. Fig 2.1:Stereo lithography 3.2 Laminated Object Manufacturing In this technique, developed by Helisys of Torrance, CA, layers of adhesive-coated sheet material are bonded together to form a prototype.. As shown in the figure below. Fig2.2: Schematic diagram of laminated object manufacturing. A feeder/collector mechanism advances the sheet over the build platform, where a base has been constructed from paper and double-sided foam tape. Next, a heated roller applies pressure to bond the paper to the base. A focused laser cuts the outline of the first layer into the paper and then cross-hatches the excess area (the negative space in the prototype). Cross-hatching breaks up the extra material, making it easier to remove during post-processing. During the build, the excess material provides excellent support for overhangs and thin-walled sections. After the first layer is cut, the platform lowers out of the way and fresh material is advanced. The platform rises to slightly below the previous height, the roller bonds the second layer to the first, and the laser cuts the second layer. This process is repeated as needed to build the part, which will have a wood-like texture. Because the models are made of paper, they m ust be sealed and finished with paint or varnish to prevent moisture damage. Helisys developed several new sheet materials, including plastic, water-repellent paper, and ceramic and metal powder tapes. The powder tapes produce a â€Å"green† part that must be sintered for maximum strength. As of 2001, Helisys is no longer in business. 3.3 Selective Laser Sintering Developed by Carl Deckard for his master’s thesis at the University of Texas, selective laser sintering was patented in 1989. The technique, shown in Fig,  uses a laser beam to selectively fuse powdered materials, such as nylon, elastomer, and metal, into a solid object. Parts are built upon a platform which sits just below the surface in a bin of the heat-fusable powder. A laser traces the pattern of the first layer, sintering it together. The platform is lowered by the height of the next layer and powder is reapplied. This process continues until the part is complete. Excess powder in each layer helps to support the part during the build. SLS machines are produced by DTM of Austin, TX. Fig 2.3: Schematic diagram of selective laser sintering. 3.4 Fused Deposition Modeling In this technique, filaments of heated thermoplastic are extruded from a tip that moves in the x-y plane. Like a baker decorating a cake, the controlled extrusion head deposits very thin beads of material onto the build platform to form the first layer. Fig2.4: schematic diagram of fused deposition modeling. The platform is maintained at a lower temperature, so that the thermoplastic quickly hardens. After the platform lowers, the extrusion head deposits a second layer upon the first. Supports are built along the way, fastened to the part either with a second, weaker material or with a perforated junction. 3.5 Solid Ground Curing Developed by Cubital, solid ground curing (SGC) is somewhat similar to stereolithography (SLA) in that both use ultraviolet light to selectively harden photosensitive polymers. Unlike SLA, SGC cures an entire layer at a time. Figure 5 depicts solid ground curing, which is also known as the solider process. First, photosensitive resin is sprayed on the build platform. Next, the machine develops a photomask (like a stencil) of the layer to be built. This photomask is printed on a glass plate above the build platform using an electrostatic process similar to that found in photocopiers. The mask is then exposed to UV light, which only passes through the transparent portions of the mask to selectively harden the shape of the current layer. Fig 2.5: Schematic diagram of solid ground curing. After the layer is cured, the machine vacuums up the excess liquid resin and sprays wax in its place to support the model during the build. The top surface is milled flat, and then the process repeats to build the next layer. When the part is complete, it must be de-waxed by immersing it in a solvent bath. SGC machines are distributed in the U.S. by Cubital America Inc. of Troy, MI. The machines are quite big and can produce large models. 3.6 3D Printing Ink-Jet Printing refers to an entire class of machines that employ ink-jet technology. The first was 3D Printing (3DP), developed at MIT and licensed to Soligen Corporation, Extrude Hone, and others. The ZCorp 3D printer, produced by Z Corporation of Burlington, MA is an example of this technology. As shown in Figure 6a, parts are built upon a platform situated in a bin full of powder material. An ink-jet printing head selectively deposits or â€Å"prints† a binder fluid to fuse the powder together in the desired areas. Unbound powder remains to support the part. The platform is lowered, more powder added and leveled, and the process repeated. When finished, the green part is then removed from the unbound powder, and excess unbound powder is blown off. Finished parts can be infiltrated with wax, CA glue, or other sealants to improve durability and surface finish. Typical layer thicknesses are on the order of 0.1 mm. This process is very fast, and produces parts with a slightly grainy surface. ZCorp uses two different materials, a starch based powder (not as strong, but can be burned out, for investment casting applications) and a ceramic powder. Machines with 4 color printing capability are available. 3D Systems’ version of the ink-jet based system is called the Thermo-Jet or Multi-Jet Printer. It uses a linear array of print heads to rapidly produce thermoplastic models (Figure 6d). If the part is narrow enough, the print head can deposit an entire layer in one pass. Otherwise, the head makes several passes. Sanders Prototype of Wilton, NH uses a different ink-jet technique in its Model Maker line of concept modelers. The machines use two ink-jets (see Figure 6c). One dispenses low-melt thermoplastic to make the model, while the other prints wax to form supports. After each layer, a cutting tool mills the top surface to uniform height. This yields extremely good accuracy, allowing the machines to be used in the jewelry industry. Ballistic particl e manufacturing, depicted in  Figure 6b, was developed by BPM Inc., which has since gone out of business. Fig 2.6: Schematic diagrams of ink-jet techniques. 4. The Basic Process of 3D Printing Although several rapid prototyping techniques exist, all employ the same basic five-step process. The steps are: 1. Create a CAD model of the design 2. Convert the CAD model to STL format 3. Slice the STL file into thin cross-sectional layers 4. Construct the model one layer atop another 5. Clean and finish the model CAD Model Creation: First, the object to be built is modeled using a Computer-Aided Design (CAD) software package. Solid modelers, such as Pro/ENGINEER, tend to represent 3-D objects more accurately than wire-frame modelers such as AutoCAD, and will therefore yield better results. The designer can use a pre-existing CAD file or may wish to create one expressly for prototyping purposes. This process is identical for all of the RP build techniques. Conversion to STL Format: The various CAD packages use a number of different algorithms to represent solid objects. To establish consistency, the STL (stereolithography, the first RP technique) format has been adopted as the standard of the rapid prototyping industry. The second step, therefore, is to convert the CAD file into STL format. This format represents a three-dimensional surface as an assembly of planar triangles, â€Å"like the facets of a cut jewel.† 6 The file contains the coordinates of the vertices and the direction of the outward normal of each triangle. Because STL files use planar elements, they cannot represent curved surfaces exactly. Increasing the number of triangles improves the approximation, but at the cost of bigger file size. Large, complicated files require more time to pre-process and build, so the designer must balance accuracy with manageability to produce a useful STL file. Since the STL format is universal, this process is identical for all of the RP build techniques. Slice the STL File: In the third step, a pre-processing program prepares the STL file to be built. Several programs are available, and most allow the user to adjust the size, location and orientation of the model. Build orientation is important for several reasons. First, properties of rapid prototypes vary from one coordinate direction to another. For example,  prototypes are usually weaker and less accurate in the z (vertical) direction than in the x-y plane. In addition, part orientation partially determines th e amount of time required to build the model. Placing the shortest dimension in the z direction reduces the number of layers, thereby shortening build time. The pre-processing software slices the STL model into a number of layers from 0.01 mm to 0.7 mm thick, depending on the build technique. The program may also generate an auxiliary structure to support the model during the build. Supports are useful for delicate features such as overhangs, internal cavities, and thin-walled sections. Each RP machine manufacturer supplies their own proprietary pre-processing software. Layer by Layer Construction: The fourth step is the actual construction of the part. Using one of several techniques (described in the next section) RP machines build one layer at a time from polymers, paper, or powdered metal. Most machines are fairly autonomous, needing little human intervention. Fig 3.2 Layer by Layer Construction Clean and Finish: The final step is post-processing. This involves removing the prototype from the machine and detaching any supports. Some photosensitive materials need to be fully cured before use. Prototypes may also require minor cleaning and surface treatment. Sanding, sealing, and/or painting the model will improve its appearance and durability. 3D printing VS Conventional Technologies 3DP does not—and will not—replace completely conventional technologies such NC and high-speed milling, or even hand-made parts. Rather, one should regard 3DP as one more option in the toolkit for manufacturing parts. Figure depicts a rough comparison between 3DP and milling regarding the costs and time of manufacturing one part as a function of part complexity10. It is assumed, evidently, that the part can be manufactured by either technology such that the material and tolerance requirements are met. Fig5.1: 3DP vs. conventional machining Application of 3D printers The concept of custom manufacturing is exciting to nearly everyone, but it always seems to be something that will happen in the â€Å"future†. Gibson was right and the following list of applications for 3D printers show the truth in the saying â€Å"The future is here. It’s just not evenly distributed yet.† The following items are all available for purchase or are being used in industry now. We are still a long way from Replicators like the ones from Star Trek: The Next Generation, but we probably won’t have to wait til the 24th century either. 1. Art 3D printing allows artists to create objects that would be incredibly difficult, costly, or time intensive using traditional processes. These sculptures by Bathsheba Grossman are exquisitely complex and manufactured using a laser sintering process. 2. Action Figures Blood Elves and band mates can both be brought to life using 3D printers. These two were created using Zcorp. machines which apply glue ink and powder in fine layers slowly creating a replica of one of your characters. Figure Prints allows you to create characters from Warcraft, Rock band and Spore printing services are coming soon. A number of other sites allow you to pull data from Second Life and your own 3D programs. 3. Jewelry Jewelry makers were some of the first to use 3D printing in their manufacturing process, however they do not use metal printers, but rather ones that use wax. In a process called â€Å"investment casting† a piece of jewelry is sculpted or printed out of wax. Plaster is then poured on either side. Molten metal is poured onto the wax which melts out leaving a metal version of your wax sculpt in its place in the plaster. This piece is then finished and polished by a jeweler. Many independent jewelers have been using high tech printers in their businesses and an innovative company called Paragon Lake has combined this process with web based design tools to offer an infinite inventory to the masses of jewelry stores. 4. Hearing Aids 3D printers can also make things more functional. In the case of hearing aids  a cast of your ear canal is made. The casting is digitized using a 3D scanner and a perfect replica of your ear is printed from that ensuring a great fit and improving the quality. 5. Prototypes Prototyping in product development is currently the biggest use of 3D printing technology. These machines allow designers and engineers to test out ideas for dimensional products cheaply before committing to expensive tooling and manufacturing processes. 6. Home Decor Home goods are structurally simple but endlessly decorative and are perfect matches for 3D printing. This service, called â€Å"Shapeways Creator† allows you to create products like this lamp with any selection of words that have relevance to you (wedding vows, a favorite poem, etc.). Another company called JuJups allows you to make a customized picture frame using intelligent design tools and a zCorp printer. 7. Models Sales folks lives get much easier when you can have models like this of your product printed up for show and tell. 8. Components/Manufacturing Many of the examples so far are somewhat gimmicky or decorative, However in some industries 3D printing is displacing traditional manufacturing entirely. In the left hand picture a surgical knee replacement implant has been designed and manufactured to fit a patient’s joint perfectly. On the right, high tolerance engine parts were printed using a process called â€Å"Electron Beam Melting† and finished with traditional machining processes. While not the norm these uses begin to suggest what is possible in medicine and industry. 9. Medicine 3D World of Warcraft characters are cool, but these tools have the power to help save lives. Surgeons are using 3d printers to print body parts for reference before complicated surgeries. Other 3D printers are used to create bone grafts for patients who have suffered traumatic injuries. Looking further in the future scientist are working on PRINTING replacement organs. Personal Fabrication indeed! 3D Printing Essay 3D Printing Today and Tomorrow I chose to do my research paper on 3D printing, were we are today and what the future looks like. While researching this project I learned that 3D printing has been around since the 80’s, and that it is also known as additive manufacturing. I chose this topic for a few reasons; first off this is a topic that has interested me fo a while now and I enjoy learning more about it. I believe this technology is going to have a huge impact on our future, like the computer, and the internet it will change the way we do things. I like that its impact is not limited to one area. I highlight in my project seven different areas that 3D printing is already being used and is reshaping those industries. One of these industries is architecture, construction, and engineering. Architects are using 3D printing to save time when putting together their scale models. In the future there will be no limitations to their designs; the reason for this being that construction companies are now experimenting with 3D printing to build parts of buildings. They have started to print using concrete and have been able to print up some wild angles and designs. These were difficult to pull off before because it was hard to make the form to pour the concrete. In the future architects and project managers will be able to work together and print sections of a building in one location, then move and assemble on sight. Just like architects, engineers are using 3D printing to print up scale models of their designs. With the advances in this technology they are able to print these items with moving and working parts. Another one of these industries is the automotive and aerospace industry. In the automotive industry, designers will be able to print up models. Auto makers have also been able to print parts, and have successfully printed a whole working car. In the future 3D printers will be more common in the average home, because of this consumers will be able to go online and print  up certain types of replacement parts. This will be nice especially when it comes to hard to find or dealer only parts. The same will go for the aerospace industry as far as being able to print models, and replacement parts. NASA will be launching a mission soon were they will be sending a 3D printer in to space, and they will test printing in zero gravity. If they are successful this will mean that they can put a 3D printer on their shuttles and print parts in space. This will cut down on the weight in the shuttles when they launch but still allow them to print supplies while in space. The Military is using this technology the same way. They have started testing 3D printing while in the field. Just like the aerospace industry, the ability to print in the field will cut down on the amount of supplies they have to carry. It will also give them the ability to print and repair vehicles and machinery while out in the field. There are a few problems when it comes to this industry, the main one being weapons. Fully functional guns have been printed, they have done this using materials other than metal. The government and DOD has made it illegal for anyone to print guns, and they have ordered all open source instructions to be removed from the internet. However officials fear that the problem will be that just like music, movies, programs, and other online files that are shared it will not keep these plans out of the hands of people who really want to get them. An exciting industry that this technology is changing is the medical and dental field. Dentist are already using this tech to print dentures using x-rays and scans to perfectly match the patience. In the medical field they have successfully printed bone fragments, more specifically part of a skull and a human jaw bone. Doctors have used these items in patents. In China they have developed a printer that uses human cells. This was made with the intent to one day print human replacement organs. The thought behind this is they would be able to print an organ using your DNA, therefore your body would not reject it, and you would not have to wait as long for a transplant. Doctors have successfully printed a working heart valve, and they expect the FDA to approve usage of these within the next year. The current method is to use heart valves from pigs, and those only have a 3year  lifespan, again by using your cells and DNA to make these parts your body will accept them and they will last longer. I was surprised to hear that this tech is being used in the fashion industry. Designers are using this to print wild looking clothes, shoes, head ware, and jewelry. As printers become more common in our households we will be able to do the same. Imagine being able to go online to a designers web site or even designing your own clothes and printing them up at home. The other nice thing would be the ability to print clothing and accessories that are a custom fit to you. I read an article were a history teacher in Europe used 3D printing to print replicas of ancient Egyptian artifacts so that he could give his class a more hands on approach to learning. I thought how awesome the possibilities will be for education, they will be able to use it for everything from printing supplies to doing what this teacher did and giving students the ability to observe items that we normally would not be able to touch. This would also open up learning opportunities to teach people how to design and use this technology. The opportunities will be endless, especially for the trade schools that deal with architecture, engineering, automotive, art & design, culinary, and many more. The culinary industry was another industry I was surprised to find this tech, however it does make sense. 3D printing is being used now to make elaborate food designs using semi liquids like chocolate and cheese. They are also able to design and print molds for gelatins, and cakes. Just like in the medical field scientist hope to be able to use bio printers to print food like meats, fruits, and veggies. I am not sure how ready we are to eat 3D printed food, but who knows in the future this may become the norm. http://en.wikipedia.org/wiki/3D_printing http://www.linkedin.com/today/post/article/20131031142926-48342529-the-future-of-3d-printing http://www.explainingthefuture.com/3dprinting.html http://techcrunch.com/2013/10/02/gartner-3d-printer-market-forecast/

Machiavelli Ruler Essay

Elizabeth’s religious and political policies displayed her cunning characteristics of being both loved. Her use of justification by force rather than law was effective and was a main reason for her success. The Queen surrounded herself with shrewd and wise advisors but also carefully questioned the motives of her closest consultants. In Machiavellian style, Elizabeth’s religious policy fluctuated between toleration and repression according to the needs of the present time. But despite the conflicts between the Catholics and Protestants, Elizabeth still pursued a middle way between the feuding religions. In the Elizabethan Settlement, Elizabeth and Parliament required conformity in the Church of England but allowed people to worship Protestantism and Catholicism privately. In the Thirty-Nine Articles, Elizabeth defined the Anglican Church as following the Protestant doctrine but keeping the Catholic hierarchy. The Queen abolished presbytery structure and other corrupt church practices but kept a centralized figure head (monarchy). Elizabeth as well showed little mercy to anyone who threatened her rule. Religious extremists such as Puritans and Catholics were given a choice to reform or be exiled in Elizabeth’s Conventicle Act. Because of these actions, Elizabeth is also considered a politique: she put political over religious matters. Another example of Elizabeth following the Machiavellian concept is her refusal of marriage to King Philip II of Spain. Elizabeth was married to her country and did not want a King to come along and change the religion and take all her power. In her foreign policy, she was systematic because it was designed to keep her in power. One example of a threat to Elizabeth’s power was Mary Queen of Scots. Many of Elizabeth’s Catholic enemies wanted to see her replaced by Mary. Because of the many threats Elizabeth received from her, Mary was executed, despite being Elizabeth’s relative. Elizabeth killed Mary for the good of England and did not let any person interfere with her ruling. Although Elizabeth dealt horribly with those who tried to overthrow her, Elizabeth’s people loved her even after her death because of her strong command of respect and loyalty. By following the Machiavellian style, Queen Elizabeth I became seen as one of the most influential ruler who led England successfully. In French history, Prince Henry of Navarre is known as being Machiavellian. Prince Henry, who although was Protestant, converted to a Catholic for the good of France. Since the Bourbon Prince was Protestant and a legal heir to the French throne, it posed a problem because of France being strongly Catholic. Although there was an attempt by Henry III to grant Huguenots almost complete freedom in the Peace of Beaulieu, it fails and Henry III seeks aid from Henry of Navarre. After Henry III dies, Prince Henry of Navarre succeeds him and becomes King Henry IV. Because Spain was intervening in other matters, Henry IV became stronger in his rule. He was widely liked by France and did what was best for the country. The King put his politics and image with the French people before his religion. He converted from Calvinism to Catholicism to please the masses of France. In the Edict of Nantes, Henry made a formal religious settlement for the Huguenots. The Huguenots received religious toleration and private worshipping outside of Paris. The Edict was considered a truce rather than religious tolerance as it gave the Huguenots protection. King Henry issued the edict in order to save the national unity of France. He saved France from religious turmoil even if it meant for him to give up his own religion. â€Å"Paris is worth the mass† is one of his famous sayings. He asserts that it is more important to secure the unity and safety of a nation than to not be stubborn and not follow the mass. King Henry IV was one of the most popular French kings, both during and after his reign. He showed great care for the welfare of his subjects and displayed an unusual religious tolerance for the time. King Henry sacrificed a great amount for the good of his country by putting political over religious matters and doing whatever it takes to reach success. Machiavelli has had enormous influence on the world’s successful rulers. People like Queen Elizabeth I and King Henry IV ruled their country with great attention. These rulers were war wise, noble, brave, strong, and kept faith in others at a minimum. Elizabeth and Henry did what was best for their country, even if it meant sacrificing religion. They used any means to stay in power. Elizabeth I and Henry IV truly displayed Machiavellian characteristics through the way they used their power.

Battle of Stony Point in the American Revolution

Battle of Stony Point in the American Revolution The Battle of Stony Point was fought July 16, 1779, during the American Revolution (1775-1783). In the summer of 1779, the leadership of the Continental Army decided to mount an assault against Stony Point, NY after the position had been occupied by the British. The assignment was given to Brigadier General Anthony Wayne and the Corps of Light Infantry. Striking at night, Waynes men conducted a daring bayonet attack that secured Stony Point and captured the British garrison. The victory provided a needed boost for American morale and Wayne received a gold medal from Congress for his leadership. Background In the wake of the Battle of Monmouth in June 1778, British forces under Lieutenant General Sir Henry Clinton largely remained idle in New York City. The British were watched by General George Washingtons army which assumed positions in New Jersey and to the north in the Hudson Highlands. As the 1779 campaigning season began, Clinton sought to lure Washington out of the mountains and into a general engagement. To accomplish this, he dispatched around 8,000 men up the Hudson. As part of this movement, the British seized Stony Point on the eastern bank of the river as well as Verplancks Point on the opposite shore. General Sir Henry Clinton. Photograph Source: Public Domain Taking possession of the two points at the end of May, the British began fortifying them against attack. The loss of these two positions deprived the Americans of using Kings Ferry, a key river crossing over the Hudson. As the main British force withdrew back to New York having failed to force a major battle, a garrison of between 600 and 700 men was left at Stony Point under the command Lieutenant Colonel Henry Johnson. Consisting of imposing heights, Stony Point was surrounded by water on three sides. On the mainland side of the point flowed a swampy steam that flooded at high tide and was crossed by one causeway. Dubbing their position a little Gibraltar, the British constructed two lines of defenses facing west (largely fleches and abatis rather than walls), each manned with around 300 men and protected by artillery. Stony Point was further protected by the armed sloop HMS Vulture (14 guns) which was operating in that part of the Hudson. Watching the British actions from atop nearby Buckberg Mountain, Washington was initially reluctant to assault the position. Utilizing an extensive intelligence network, he was able to ascertain the strength of the garrison as well as several passwords and the locations of sentries (Map). The American Plan Reconsidering, Washington decided to move forward with an attack utilizing the Continental Armys Corps of Light Infantry. Commanded by Brigadier General Anthony Wayne, 1,300 men would move against Stony Point in three columns. The first, led by Wayne and consisting of around 700 men, would make the main attack against the southern side of the point. Scouts had reported that the extreme southern end of the British defenses did not extend into the river and could be flanked by crossing a small beach at low tide. This was to be supported by an attack against the northern side by 300 men under Colonel Richard Butler. To ensure surprise, Waynes and Butlers columns would make the assault with their muskets unloaded and relying solely on the bayonet. Each column would deploy an advance force to clear obstacles with a 20-men forlorn hope to provide protection. As a diversion, Major Hardy Murfree was ordered to stage a diversionary attack against the main British defenses with around 150 men. This effort was to precede the flank attacks and serve as signal for their advance. To ensure proper identification in the darkness, Wayne ordered his men to wear pieces of white paper in their hats as a recognition device (Map). Battle of Stony Point Conflict: American Revolution (1775-1783)Dates: July 16, 1779Armies and Commanders:AmericansBrigadier General Anthony Wayne1,500 menBritishLieutenant Colonel Henry Johnson600-700 menCasualties:Americans: 15 killed, 83 woundedBritish: 20 killed, 74 wounded, 472 captured, 58 missing The Assault On the evening of July 15, Waynes men gathered at Springsteels Farm approximately two miles from Stony Point. Here the command was briefed and the columns began their advance shortly before midnight. Approaching Stony Point, the Americans benefited from heavy clouds which limited the moonlight. As Waynes men neared the southern flank they found that their line of approach was flooded with two to four feet of water. Wading through the water, they created enough noise to alert the British pickets. As the alarm was raised, Murfrees men began their attack. Pushing forward, Waynes column came ashore and began their assault. This was followed a few minutes later Butlers men who successfully cut through the abatis along the northern end of the British line. Responding to Murfrees diversion, Johnson rushed to the landward defenses with six companies from the 17th Regiment of Foot. Battling through the defenses, the flanking columns succeeded in overwhelming the British and cutting off those engaging Murfree. In the fighting, Wayne was temporarily put out of action when a spent round struck his head. Battle of Stony Point, 1779. Library of Congress Command of the southern column devolved to Colonel Christian Febiger who pushed the attack up the slopes. The first to enter the innermost British defenses was Lieutenant Colonel Francois de Fluery who cut down the British ensign from the flagstaff. With American forces swarming in his rear, Johnson was ultimately compelled to surrender after less than thirty minutes of fighting. Recovering, Wayne sent a dispatch to Washington informing him, The fort garrison with Col. Johnston are ours. Our officers men behaved like men who are determined to be free. Aftermath A stunning victory for Wayne, the fighting at Stony Point saw him lose 15 killed and 83 wounded, while British losses totaled 20 killed, 74 wounded, 472 captured, and 58 missing. In addition, a host of stores and fifteen guns were captured. Though a planned follow-on attack against Verplancks Point never materialized, the Battle of Stony Point proved a vital boost to American morale and was one of the final battles of the conflict to be fought in the North. Visiting Stony Point on July 17, Washington was extremely pleased with the result and offered lavish praise upon Wayne. Assessing the terrain, Washington ordered Stony Point abandoned the next day as he lacked the men to fully protect it. For his actions at Stony Point, Wayne was awarded a gold medal by Congress.

Reaction paper 2 parts 7 and 8 - Essay Example Given this second viewpoint, I would say that this hardly contributes to the definition of masculinity, because it informs on what women are based on what men are, but does not establish what being a man is. Recent research into masculinity has underscored this male-female polarity. In the American setting, cultural masculinity studies have dealt nearly exclusively in heterosexual masculinity behaviour and attributes (Traister, 2000, p. 274), which precludes homosexual masculinity as a seeming misnomer since it does not fit into the polar male-female model. Cultural changes are at the center of an evolving meaning given to â€Å"masculinity†, with the socio-economic developments in Europe defining the directions of Western thought in this regard. When Renaissance secular culture spread, interest in sexuality broke free of its strict regulation during the monastic period. When European monarchies embarked on overseas conquests and commerce prospered, the male role became identified with business, finance, and overall economic success. The fact that a man had more, and more expensive, possessions made him more of a man, better able to provide for his wife, their children, and his household members. The patriarchal system was further strengthened by the imperial monarchy where the power of men over women was further institutionalised (Connell, 1995, p. 248), formalising men’s domestic authority over women and enforcing the latter’s dependence upon the former’s economic property, not because the women did nothin g to contribute to it, as they often managed the running of the estate and the network of alliances among the gentry (p. 249), but because they could not legally own property. The Western image of masculinity is an ideal that was fostered upon the colonial East as a means of further strengthening the rule of the colonizers upon the conquered (Krishnaswamy, 2002, p. 292). Primary among these ideals is the image of the white, elegantly proportioned,

Relevant theories use in CESIM simulation program Essay

Relevant theories use in CESIM simulation program - Essay Example This research will begin with the statement that among the marketing theories applicable to marketing the brand of mobile phones includes the game theory, signaling, and innovation theories among many others. Just as the name suggests, game theory analyses the position and effects of competition on the success and profitability of a brand. The theory asserts that a business must strive to achieve the best and most preferred outcomes despite the competition. Marketers must, therefore, observe the behaviors and product features of their competitors in order to develop appropriate brands to counter such. Signaling just as with the game theory advises marketers to observe the actions of the competition, this way it becomes possible for the marketer to position his product strategically. Innovation theory, on the other hand, requires marketers to develop creative products in order to influence the reception of the brand in the market. Marketing a mobile phone requires marketers to conside r the theories thereby positioning the product strategically. Besides the marketing theories, marketers must employ several other strategies to enhance the positioning of the product in order to enhance productivity as the discussion below portrays. Marketing is a fundamental management function whose primary objective is to determine, anticipate, and satisfy the market demand. By doing this, the marketing team meets the current demand while influencing effective production in view of increasing its market share.
