Dolphins Essay Example for Free
Dolphins Essay Bottlenose dolphins can grow to be thirteen feet long and weigh up to 600 pounds (Bottlenose Dolphins). This makes bottlenose dolphins the largest of the beaked dolphins (Dolphin Research Center). Bottlenose dolphins have slick and rubbery skin with no sweat glands or hair. Their epidermis is ten to twenty times thicker than that of other mammals. It can be replaced every two hours, which is nine times faster than human skin. The peeling of their skin helps to reduce drag when they swim. The skin is dark gray on their backs, and fades to white or pink on their bellies. This coloring is called countershading. From above the dolphins blend in with the dark water below, and from underneath they blend in with the sunlight. Countershading helps dolphins hide from predators and prey (Bottlenose Dolphins). Bottlenose dolphins are piscivors, or fish-eaters. They have eighty-eight to one hundred small, sharp teeth for grasping slippery squid and fish (Parker and Burton) (Dolphin Research Center). When catching fish, dolphins usually herd a school of fish together and then dash through the school one at a time to feed. It has been observed where 200 bottlenose dolphins were in a single row, working together to find food. Dolphins can also use their tail flukes to toss a fish out of the water and then retrieve the shocked prey (Bottlenose Dolphins). If a dolphin catches a large fish, it will smack the fish on the ocean floor or the waterââ¬â¢s surface to break it into smaller portions (McClintock). After a dolphin catches its prey, it uses its tongue to swallow the fish and push the water out of its mouth (Dolphin Research Center). Dolphins can eat up to thirty pounds of fish in one day, so it is helpful that they have three stomach compartments, similar to that of a cow (McClintock) (Lockley 69). Bottlenose dolphins find fish by using echolocation. This is when a dolphin sends out a beam of short sonar pulses from its melon, or forehead. The beam reflects off of fish or other objects and echoes back to the lower jaw. The echoes are then sent to the ear bones where they are characterized. Using echolocation, dolphins are able to locate prey that is buried up to one and a half feet under the sand (Cahill 140-141). Bottlenose dolphins are excellent swimmers. They can jump up to sixteen feet in the air. Three to seven miles per hour is their normal swimming speed, but they can reach speeds of eighteen to twenty-two miles per hour. Dolphins also porpoise, which is when a dolphin swims fast enough to repetitively come out of the water and back under the water in one swift movement. This uses less effort than swimming fast at the oceanââ¬â¢s surface. When dolphins swim in deep open water, they often dive. They dive to 150 feet regularly, but they have been recorded diving up to 2,000 feet (Bottlenose Dolphins). When a dolphin needs to breathe, it comes to the surface, exhales, and then inhales. If a dolphin stays underwater for a very long time, it can exhale at over 100 miles per hour (Cahill 77). It only takes about 0. 3 seconds for dolphins to breathe (Bottlenose Dolphins). Dolphins exchange 80% of their lung air with each breath; when humans breathe, they exchange only 17% (Bottlenose Dolphins). They come to the surface to breathe every twenty-eight seconds when they are not diving, but they can hold their breath for up to twelve minutes (McClintock) (Bottlenose Dolphins). Before a dolphin can hold its breath for a long time, it has to slow its heart rate down to twelve beats per minute. A slow heart rate helps to conserve energy and oxygen while diving (Dolphin Research Center). In order for dolphins to be able to swim, they have to have fins. Bottlenose dolphins have three different types of fins on their bodies. The most recognizable is the dorsal fin. It is located in the center of the back and is the cause of dolphins sometimes being confused with sharks. The dorsal fin is helpful for balance but is not essential. Dolphins also have flippers on both sides of their bodies called pectoral fins that are used to steer. The bones in pectoral fins look similar to human hands because they have five digits. The two parts of a dolphinââ¬â¢s tail are called flukes. Tail flukes are made up of tough connective tissue with no bones or muscle. The tailââ¬â¢s spread is 20% of the total body length. The dolphinââ¬â¢s back muscles move the flukes up and down to push the dolphin through the water. All of the fins and flippers use the process of countercurrent heat exchange to conserve body heat. This means that the arteries in the fins are surrounded by smaller veins so that some of the heat from the blood is transferred to the blood in the veins instead of being released to the environment (Bottlenose Dolphins). Dolphins need to conserve heat to stay warm in cooler waters. The lifespan of a bottlenose dolphin is twenty to thirty years. They can reproduce every three years for their entire lives starting at the age of six (Bottlenose Dolphins) (Cahill 98). The gestation period lasts twelve months. Baby dolphins, called calves, are usually born tail-first to prevent drowning, and the umbilical cord between the mother dolphin and calf snaps during birth (Cahill 98) (McClintock). ââ¬Å"85% of all firstborn calves dieâ⬠(McClintock). Newborn calves typically weigh twenty-two to forty-four pounds and are thirty-nine to fifty-three inches long (Bottlenose Dolphins). Since dolphins are mammals, calves drink milk produced in the motherââ¬â¢s body (World Book 296). Mother dolphins have to swim constantly with their calves in their ââ¬Å"slipstreamâ⬠because newborns do not have enough blubber to easily float (Hecker). At about four months old, young start to eat fish and are entirely weaned from milk between the ages of one year and eighteen months (Lockley 169). Each dolphin develops a signature whistle at one month old. In order for calves to recognize their mothers by their whistle, mothers whistle to their calves almost constantly for several days after birth (Bottlenose Dolphins). A dolphin will stay with its mother for at least six years and some dolphins stay with their mothers for their entire lives (Bottlenose Dolphins). Bottlenose dolphins are very social animals. They travel in pods, which are groups of two to fifteen dolphins (Bottlenose Dolphins). Dolphins are very protective of each other, and they have killed sharks that were too close to their pod by repeatedly hitting them in the gills (Lockley 172). They will also try to save an injured or dead dolphin by keeping it at the surface for hours or even days (Lockley 19). Bottlenose dolphins are usually very friendly towards humans. Some wild dolphins even go into bays and interact with them (Dolphin Research Center). Dolphins also love to have fun. In captivity, they enjoy teasing each other and humans that are around their tanks (Lockley 48). In the wild, dolphins like to ride ocean waves or a boatââ¬â¢s stern or bow wake (Bottlenose Dolphins). They sometimes toss jellyfish and seaweed to one another and use plastic, seaweed, or other objects as ââ¬Å"dolphin jewelryâ⬠on their fins, beaks, and necks (Cahill 93). Bottlenose dolphins truly are intriguing and individual animals. Itââ¬â¢s hard to believe that some people actually hunt them. Beloved and admired by many, they should be protected in both captivity and the wild. Bottlenose dolphins have been entertaining people in for over eighty years, and hopefully they will continue to do so for many years to come.

Saras Secret Essay -- essays papers
Saras Secret Moving to the big city was a big step for Sara. Her parents always warned her about the dangers of city life, but she never let the warnings hinder her decision. Her dream of a fast paced life has been with her for as long as she could remember, and nothing could change her mind. Sara was brought up in a small town about 200 miles from the city. This was a town in which everyone was friends with everyone, and most of the doors where never locked. Looking at this town was like looking at a painting that would be hanging up in a museum somewhere. In fact, Sara's house looked like, it too, would have its own painting. Nothing was ever out of place, it even seemed as though each blade of grass knew that it had a particular position in which it need to stay, and the inside of their house was no different. Her parents where very protective over their only child. They always knew everything that went on in their daughterââ¬â¢s life; or so they thought. Sara kept something secret from her parents for as long as she could remember. Sara was born with something so different that she felt that if her parents ever found out, they wouldn't ever be able to accept it. After Sara graduated from high school she felt as though she needed to get out of the life she knew, and start over in a whole new environment. Convincing her parents that she should move to the city was the hardest part for her, but finally after months of constant debating, her parents finally gave in. But they never stopped telling her how they felt. Even as Sara was walking out to the moving truck with the last box, her parents told her that she was making a mistake and that only trouble is found in big cities. But Sara wasnââ¬â¢t listening, she knew that she was going to love her new life, trouble and all. Sara's apartment was on the small size but it didnââ¬â¢t seem to make a difference to her, she was finally on her own. She found a job at an accounting firm about a week after her arrival in the city. The tall building that her new job was in was a beautiful sight to her, and at that time she knew that she belonged there. Her new office was only about 6 blocks from her new home, so most of the time she walked to work. She would often stop to look up at the tall buildings, admiring how they seemed to look like those tall trees she once saw on a road trip with her parents.... ...purse back to the women, she took him by the wrists up to the street to the nearest police officer. She told the policeman what happened and then left wondering when she was going to get her reward. Sara then started to walk up the street, to catch her breath. When she reached the spot where she had heard the first women scream, the city froze, not by her doing, but by the spirit. Again, a faint light appeared from the manhole, and turned into a manââ¬â¢s face. Sara was excited that she was finally going to get what she had been working so hard for. And then the spirit started to speak, ââ¬Å"You have done well Sara, you have saved the two people you needed to, to be able to receive your prize. But the thing is, you have already received it.â⬠Sara didnââ¬â¢t quite understand, so the spirit went on, ââ¬Å"You saved not one life, but the life of many. And you have risked a lot, so a lot is returned to you. The best reward is not of material value, but the feeling of value in yourself.â⬠The spirit then vanished just like it had appeared. Sara then knew what the spirit had taught her. Sara decided to dedicate her life to saving others, and to only use her powers for the good of mankind.

Ideals and Values for 12th Century Medieval Aristocrats
Chrà ©tien de Troyesââ¬â¢ Lancelot: The Knight of the Cart, told a tale of a mighty knight. It has the air, to us, of fable. It was of fabrication as two cults of the time, courtly love and honor, dominated the story. These cults were parts of a set of medieval aristocratic ideals and values. Within this set, the cults had supportive notions of hospitality, oaths, service, and military prowess. Courtly love pushed the tale into existence when Lancelot stepped onto the cart and courtly love pushed the tale to completion with the death of Meleagant at the hands of Lancelot. Lancelot put into motion these actions. Lancelotââ¬â¢s love for Queen Guinevere bound him to honorable displays of his devotion to her.Chrà ©tienââ¬â¢s tale began with Meleagantââ¬â¢s appearance at King Arthurââ¬â¢s court at Camelot. He informed King Arthur that :ââ¬Å"â⬠¦King,If you have a single knightIn this court of yours you can trustTo take your queen to the woods,Where Iââ¬â¢ll be goi ng when Iââ¬â¢m finishedHere, then Iââ¬â¢ll agreeTo let him have those prisonersIââ¬â¢ve got in my dungeons, providedHe can defeat me in battle,It being understoodThat possession of your queen is the prizeFor victory.â⬠â⬠¦ (lines 69-80).Those at court did not immediately secure the return of the Queen. She was gone. Chrà ©tien soon related how a knight (Lancelot) jumped into a cart driven by a dwarf. Those having committed criminal or despicable acts occupied such a cart in those days. Lancelot entered the cart since the dwarf promised to later reveal the whereabouts of the Queen. Chrà ©tian noted :â⬠¦and the knightFollowed along behindFor several steps, not climbingRight up. But his hesitant shameWas wrong. â⬠¦(360-364).This delay on the part of Lancelot came back to thwart his efforts when he had gotten the release of the Queen from her captor. She said :ââ¬Å"Indeed? Didnââ¬â¢t the cartShame you the least little bit?You must have hesitated,For you lingered a good two steps.And that, you see, was my soleReason for ignoring your presence.â⬠à (4491-4496).This rigidity characterized the cult of honor as exemplified by Lancelotââ¬â¢s actions. If an affair of honor came about, then the knight must perform in the honorable way. Yet there were levels of honor as when Meleagant, described as a pitiless brave fool, subscribed to a higher honor of battling Lancelot at King Arthurââ¬â¢s court in a yearââ¬â¢s time and agreed to forgo combat at an earlier time (3886-3895).Chrà ©tien saw that honor in service to love ignored common sense and reason. Reason did not include in its realm the working of the heart. Love had its way. For loveââ¬â¢s commands, even shame endured. Deep in reflection, Lancelot had no defense against love. He did completely forget himself. An opponent challenged Lancelot three times before crossing a stream. The opponent struck Lancelot with Lancelot still in loveââ¬â¢s command. The opponent ha d unfairly struck him. Lancelot wanted to avenge this disturbance of his revery (891-893). Outside revery he was in a fair enough way but his one and only heart he entrusted to some one else such that he was constrained in a special manner (1231-1248). à He found the Queenââ¬â¢s comb. It had strands of her hair and he was ecstatic:Touching them a hundred thousandTimes, caressing with his eves,His lips, his forehead, his face.And all of it brings him happiness,Fills him with the richest delight;He presses it into his breast,Slips it between his shirtAnd his heart ââ¬â worth more than a wagon-Load of emeralds or diamonds, (1470-1478).Later, in traversing the sword bridge, the blade cut so as to maim him but the suffering was sweet since love led him on and relieved his pain (3115-3122). Still later a distraught Lancelot, thinking that the Queen is dead, attempted to kill himself by hanging himself from his saddle by means of his belt (4264-4268).Honor had its greatest demands made upon it by love but it spanned also military activity for which the knights were constantly prepared. In this preparation, a generous hospitality aided them that mostly included horses (284-289), beds (458-463), and food. For the first two, they had a choice. The mistress of a house offered Lancelot the house and the mistress of the house (938-949).Thus prepared, their military valor was a pledge, an oath, which they must uphold. A knight could be in the grip of another knight and not fight correctly; so the second knight asked to release the first knight. Then the second knight could recover his military equipment and they could then fight in the approved manner (839-852). The more honor gained in combat, the better. Accompanying a damsel involved an unspoken oath and was a very serious business since the knight was then responsible for her.A challenging knight could assault her with impunity if a challenging knight defeated the escorting knight (1304-1322). Mercy could be gr anted for the about to be vanquished but this usually entailed an oath be taken. The one who granted mercy redeemed this oath to their benefit. If one had an oath to carry out, then could not do it, there could be shame of a great dimension when another knight did the deed (4013-4019). Knights sometimes honored a pledge, for honorââ¬â¢s sake, even though it seemed not in the best interests of most of those involved as when Kay sought to have the Queen accompany him into the forest where a knight awaited :The king was upset, but his wordHad been given, and he could not revoke it,No matter how angry and sorrowfulIt made him (which was easy to see).The queen, too, was deeplyDispleased, and the whole palaceDenounced Kayââ¬â¢s pride and presumptionIn making such a demand. (179-186).Again, it could be a combatant who would not continue the fight if pledged by his lady to cease. Then the other knight must not force a continuance then and there by striking the one who no longer lifts a weapon. Meleagant, for example, struck Lancelot. à The Queen had requested Lancelot to stop fighting:à The king came hurrying downFrom the tower, to stop him. StraightTo the field of battle he went,Speaking these words to his son:ââ¬Å"Whatââ¬â¢s this? You think itââ¬â¢s fineTo go on fighting, afterHeââ¬â¢s stopped? You act like a savage!â⬠(3824-3831).The truth of the matter is that Lancelot only appeared to give up. In truth he was doing what his lady had requested of him. Later her captors said she was lying about bloodied sheets (4788-4798). This was a most grievous charge and so combat was called for. Holy relics came out and, on their knees, the parties involved did swear. Truth in other matters was another preoccupation of the aristocrats that Chrà ©tien wrote about. There were standards of truth against which the knights and others could measure their conduct. To seek death in ignorance was the action of a fool. à A fool too was one who does not truly humble oneself. A fool never lost his folly. Those nobles, not fools, did not need to seek praise to enhance their deeds and self praise did not increase oneââ¬â¢s esteem. The madness of a fool had no cure:ââ¬Å"Who do you think believes you?â⬠Said the king. ââ¬Å"All these peopleCan tell for themselves whatââ¬â¢s trueAnd False. We know youââ¬â¢re lying.â⬠(3841-3844).Far from the fool was the man as lover who was always obedient and gladly did his loverââ¬â¢s bidding in short order. He knew much about love and included in this knowledge was that honor done for love entailed no shame. Should something greatly go amiss, he would not fear death. Death desired those who were afraid of it (4283-4284).Before death there were dwarfs. Lancelot encountered two dwarfs in the tale. Neither one was up to any good. The first, described as a ââ¬Å"Low-born and disgustingâ⬠dwarf (353) did lead Lancelot astray. The dwarf lied as to knowing the Queenââ¬â¢s whereab outs but did convince Lancelot to enter the cart. The other dwarf encountered Lancelot on Lancelotââ¬â¢s approach to the water bridge. The dwarf promised to take Lancelot to a special place (5081-5084). This dwarf also lied.No one said anything about what happened to the dwarfs. Presumably, they received a suitable fate for their unbecoming behavior. Perhaps death found them soon enough without their heads. It seemed that beheading was the surefire way to ensure that the one on their way out did indeed depart. Lancelot did battle with an enemy and after having vanquished him, a woman wants the opponentââ¬â¢s head. Lancelot obliges :One swing of the sword, the headWas off, and it and the bodyFell to the ground. And the girlWas happyâ⬠¦.(2927-2930).The headless one wronged her. Lancelot had already showed mercy to the opponent. Then again the opponent had pleaded for mercy. Then too the opponent had been most impertinent with Lancelot. So the upshot of this battle was the da msel was pleased and the opponent lost his head.Another beheading occurred at the end of the tale. Meleagant reflected on how it was that Lancelot had made his way to Camelot. Meleagant had thought he had locked Lancelot in a tower from which there could be no escape. He realized that he was a victim of trickery. He was ready for something worse than great shame and humiliation (6967-6969). à In his battle with Lancelot he lost his right arm. He felt badly since he then could not strike Lancelot. Then he was smashed in the face by Lancelot. Three teeth are broken in his mouth. His state enraged him to the extent he could not speak and so did not seek mercy. Lancelot cut off his head. It was finished :And let me assure you, no oneWho was there, watching the battle,Felt the slightest pity.The king and his courtiers and ladiesWere fairly jumping for joy (7099-7103).

The Treatment Of The Transplant - 898 Words
Imagine being told you will never be able to have a child. For many women this is the case. Nearly 4500 newborn girls are born with ovaries, but no uterus. This can be very detrimental news for any women with hopes of eventually having a family. Eventually, women with this syndrome, will never have to hear that they are incapable of having a child of their own. Doctors from the Cleveland Clinic hospital in Weston, Florida are working to be the first in the United States to successfully transplant a uterus from a donor to a live women. The transplanted uterus will be taken from organ donors, as the surgery is too vigorous for a live person, though it has been done in Sweden. The uterus of a donor can survive up to eight hours outside of the body if it is kept cold. The eligible recipients of the transplant are women who are born without a uterus, had it removed or have uterine damage. The transplant recipient is only allowed up to two pregnancies with the transplanted uterus for medical reasons. After two births the recipient may choose to either have the uterus extracted or quit taking the anti-rejection drugs to let the uterus extract itself. There are many procedures that have to be done before the recipient is eligible for the transplant.

3d Printing In Construction Industry â⬠Free Samples for Students
Question: Discuss About The 3d Printing In Construction Industry? Answer: Introduction The report will discuss in detail about the concept of 3 D printing in construction industry which has been part of the industry quite some time now. The real or actual usage of the technology along with its adaptation into construction sector is now initiating to become a real thing. Contractors and architects all across the world has started building the first of its kind 3 D residential based structure which also happen to include houses as well as apartment based buildings (Laplume et al, 2016). It is also important to understand here that 3D printing is distinct from the present construction ways. The concept of this technology is actually done by using huge printers which can use a special or distinct kind of concrete as well as composed mix that is actually thicker than any other regular kind of concrete which further permits it to self supportive as it sets as per technologies like Technik (Attaran, 2017). This is why, 3 D printed elements doesnt have the similar kind of design with limitation that can actually limit the present construction methods. Moreover, there are curved as well as concrete structures as well which are developed with the help of 3 D printing can be used as hollow and using less amount of material with creation of space for building different kind of services which are internal in terms of structure based components. This will help in revolutionizing the present construction industry as well as it will be way less expensive procedure that could also impact the housing industry and make it more affordable. There are low amount of usage of material and low cost of labor that also create a way less expensive construction based methods that can create low cost options in housing (Attaran, 2017). Methodology The report will use qualitative research to understand about the topic in detail. Qualitative research shows non-quantitative side of the analysis. Qualitative research is based on collection, analysis and interpreting the data by clearly observing about the people actions and their sayings. The 3D printers are used for creating the 3D models with the small or the non-structural building components like the landscaping bricks and the decorative elements. The research is about the experimentation with the different techniques where there are ranges set under the advancement of the technology and expansion of the range with the potential applications. It includes the methods like the: The variety of the raw materials which includes the recycling of the plastics and the bioplastics concrete and the synthetic material that has been from the combination of the sand and the chemicals. The advancement of the 3D printers is also capable of handling the different materials. The fabrication methods like the printing of the wall components or handling the printing with the structural scaffolding is filled with the construction materials or the site that is for creating a full-sized wall. The fabrication that is done through the reinforcement of the concrete beams. Here, the direct printing methods are for the on-site and for the in-factory setup. One of the methods called the big delta is used for the World Advanced Saving Project where there is a production of the complete shelter to use the local materials like the mud, clay and the natural fibers. This is able to handle the areas where there is a larger supply of the emergency housing as per the requirements. The development of the 3D fabrication is called the contour crafting where the offers are for the automation and construction of the complete housing where there is electrical, plumbing and the drywall factors. Here, the emissions are for the use of the light weight with contour crafting to print the houses. Results The implications which could be analyzed by the 3D printing in the construction are: There is an onsite or the factory applications where the printed of the products is only to make use of the materials as per the requirement. There is a need to handle the few resources where less waste is generated with the reduced forms of the cost of transportation. Here, the products are printed on-site with the cost of the transportation where the printer could be expensive due to the size of the printers. The potential is mainly to create more effective and attractive designs which are for proper achieving of the shapes, where the cost of the labor is low. The reduced costs of the customized designing with the 3D printing is set to create one item with the production of the thousands. The reduced health and the safety risks are there if the 3D printing could be for the assemblies that need a proper and the specialized equipment. Ecological, economical and elaborated designs: - varied kind of business applications of 3D printing are forecasted to be more beneficial that its present set of consumer market. IT research firm like Gartner is actually estimated to be considered as compound yearly development of more than 106% and the sales should be greater than the thirteen billion US dollars by the end of 2018. With the rise in the interest in the present base for construction green by nature and the important amount of saving that it provide is compared with traditional base of building methods also suggest that more and more organizations will actually turn to 3D printing methods (Hager et al, 2016). The overall usage of the 3D printing in this industry can be treated as a huge potential and considered as an eco-friendly procedure and it also saves to the usage of new kinds of materials and solutions which is related to low level of waste production. Different construction companies like MIT and ETH are using the process of reversible concrete and also produced an additional printing procedure that helps in contesting with concrete as a solution which is temporary by nature. These companies also utilize a container kind of structure where layers are made for pebbles and are further added (Wangler et al, 2016). Those strings used here can be applied in a pattern similar to algorithmically form so that it can act as a proper binder. This further make it possible to develop almost any kind of geometrical shape that can be easily deconstructed by easily removing the binder based string. Without proper clean up that it equal to gravel and people are left without any kind of residue. In addition, almost all kind of 3D printing patterns that permits for simple kind of setup and functions with quick construction which ensures with decreased level of labor costs (Wangler et al, 2016). Reactive adaption of 3 D printers: with all the discussion about 3D kind of printing with huge printers, it is crucial to get some clarity that the products are becoming cheap by nature with tool cost remain very expensive. For the sake of technology to actually take off in the current construction sectors, with cost of tools will have to reduce significantly. In addition, there is a broader range of distinct quality material needed to make technology in 3D printing is becoming more and more popular (Wangler et al, 2016). The biggest limitations here are the construction industry but it has the tendency which can be evaluated with proven facts with a degree by different industries. Therefore, the concept of 3D printing will never bring the sudden change which can be radical by nature and further changes the industry however it rather experience a slow with increasing level of varied incorporation. Present state of the art in building printing process: after finishing the initial stage of 3D printing has become a race or competition among different architects and constructors. The current procedure utilizes a concrete based material to formulate a wall for building wall with the help of programmed level of crane. In the end, elements like plumbing, electrical lines as well as wiring must be able to print into different houses in a single level of iteration. All across the industry, there should be different kind of stories with purported achievements (Corral Walker, 2017). Space 3D printing: this technology of 3 D printing would be considered as revolutionary technology since it is meant to be used in construction and were limited to varied applications on earth. The concepts that are used by different organizations have worked well with the partners to look in all the potential with added manufacturing procedure in order to build the structure on any planet. One of the crucial and important ideas behind the concept is the regolith constructor that restricts the amount of the current mass which required to get transported into space as well. Here one of the potential ideas is based on using lunar based regolith as a main martial in construction in order to restrict the amount of mass that requires to be transported into the space (Corral Walker, 2017). An organization like foster in addition to Partners which is a London based firm work for ESA, use the material like magnesium oxide along with binding kind of salt that changes the lunar related soul i nto contracting material. Such methods or process will be utilized to construct lunar building structure along with the house for the occupants of lunar which is inflatable by nature and the modules is based on inside of such structure made from 3D printers. Discussion There are number of Chinese companies like Winsun that has claimed already to manufacture ten houses on 3D designs in a single day which happens at the cost with five thousand dollar per home. Moreover in order to make the concept of housing more reasonable and affordable, there are number of architects that hope that 3D based printing will raise the overall ability to change the buildings and homes. Earlier, the company also took this technology beyond one house and constructed a five story building and large constructed villa. The company is using a 3D printing technology that makes the parts of the building in large pieces with the help of the facility provided by the company (Strickland, 2016). The company is also assembling every piece along with on-site with added reinforcement with steel as well as insulation. According to many researches the process of 3D printing is able to save between thirty to sixty percent of waste of construction which can decrease the production by fif ty to seventy percent and further decreases the cost of labor by fifty to eighty percent. One of the research also says that the technology of 3D printers manufacture the structure scratch from basis and from layer by layer. But there is also a hope to increase the present fabrication procedure even added with crafting with contour. The concept of contour crafting and similar technologies has build a great amount of potential for bringing automation with the construction of the complete structure along with small elements. There is also a hope of a huge 3D printer that has the capacity to print the complete house in a single run which also includes that the structure and all the current conduits. The theory behind 3D printing has been in discussion around some time (Panda et al, 2016). The real usage of the 3D printer and its adaptation in the construction is now initiating and becoming the real case. Various architects as well as contractors worldwide have started to build the first draft of 3D residential structure which also includes homes along with apartments. The important question here is that the present 3D printing is unique by nature and also different from the present construction methods. The concept of 3D printing is working by utilizing the present super size printers which happen to use a special kind of concrete as well as composite mix which is actually thicker than the regular structure. This is why, 3D printer elements doesnt have the similar kind of design related limitation that can restrict the present construction methodologies. Moreover, with the help of curved as concrete structure which is created with help of 3D printing can be hollow in structure since it uses less amount materials and create a wide space for building related service that exist inside the structure related elements (Majidi, 2014). This further has revolutionized the current construction industry however the less expensive procedure that can impact the affordability of the houses. With low amount of material sue and with low labor cost can create a low cost construction ways that can in turn develop low cost housing. There are so many kinds of structure based elements that are made with the help of 3D printing and also known as crafting with the help of concrete. They use less material than the same element made by using the normal concrete that forms tools. With the help of curved concrete based structure that is actually poured into various forms that are solid and with the help of concrete crafting which is hollow by nature and permitting the space as an important service in building right inside the structure based elements of the building structure (Gross et al, 2014). It is important to understand here that the overall excitement which happens over the contour based crafting also centers and it revolves around the flexibility of the design that it provides as the architect and there is another kind of advantage that may have a greater social influence. The use of lower material along with considerable amount of low labor cost further makes it less expensive technique related to construction and there is low cost that best serve for the overall mankind in giving an inexpensive way to so many people who are presently living in low quality houses (Attaran, 2017). Conclusion This technology has been used in multiple ways by many construction companies where 3D based printing is getting involved in robotics and further embarked on a very ambitious project in order to develop the first 3D printed based bridge. Companies are also developing a computer focused robotics related arms with a tipped end that manufacture the present molten material that is rapidly setting in varied place and therefore it allows the robotic arm to develop any kind of design out of a thin air. Intelligent software can used here to function with these machines so that one can print a very complicated shape of metal with a different every time (Radenkovic et al, 2016). The main plan here for the construction companies are based on bridging the gap which consist of four kind of arms related to robotics which constantly printing the metal structure as robot is moving across it in an autonomous manner. The bridge construction is further expected to start in the month of September and wi th the help of technology it will also build different other structure with specific kind of location yet to be decided. The concept of 3D printing also evolves along with new designs that constantly developing as a creation like weapon or musical tool and even vehicles that have already been used. There is a major development that has been made in this industry and now almost more than ever with the help of introduction of infrastructure printing like bridges and many more (Radenkovic et al, 2016). The concept of 3D printing of the present infrastructure is done by utilizing large printers of infrastructure which is done by using big printers that produced a distinct concrete mix which is a thick base than any kind of standard.
