(Ed) Cheng Team: Sanjeev Gupta Abit Baral Abstract: In this article different aspects of Power Tower has been investigated. Power Tower or Heliostat power plant is one of the most promising and affordable Concentrated Solar Power technology. Different parts of the Power tower namely heliostats, central receiver, heat transfer fluid, turbine and storage tanks has been examined. Also current situation of Power Tower have been researched and compared with other Solar technology. Introduction: Power towers have a potential of being one of the lowest cost and environmental friendly solution to our power needs. Today power tower systems are often considered to be the most promising Concentrating Solar Power (CSP) technology for the future. In power tower concentrating solar power systems, numerous large, flat, suntracking mirrors, known as heliostats, focus sunlight onto a receiver at the top of a tall tower. A heattransfer fluid heated in the receiver is used to generate steam, which, in turn, is used in a conventional turbine generator to produce electricity. Some power towers use water/steam or molten salt as the heat transfer fluid. Different part of these types of power plant are analyzed in detail below. Components of CSP power tower. 1. Heliostats 2. Tower with receiver 3. Heattransfer fluid ...

...situation not only in Ireland, but all over Europe. Yeats’ special interest in the Celtic Revival Movement led him to become one of the founding members of the National Theatre of Ireland in 1904, which became the flagship for Irish playwrights and actors. In 1923 he was awarded the Nobel Prize for Literature “for his always inspired poetry, which in a highly artistic form gives expression to the spirit of a whole nation”. “Sailing to Byzantium,” written in 1926 and included in the collection The Tower, can be interpreted both as a journey taken by the speaker’s aged soul and as the process of transcendence of his own mortality by means of art. “Sailing to Byzantium,” consisting of a four eight-line stanza poem, is metered in iambic pentameter with two trios of alternating rhyme followed by a couplet. Having neither characters nor plot “Sailing to Byzantium” refers to the agony of old age and the work required to remain a vital individual. Byzantium is mainly a trading city: a center of power, knowledge and art, where “monuments of unageing intellect” (8) can be found. In the speaker’s view, Byzantium is “no country for old man” (1), but a city crowded by younger generations. Yeats thinks of aged men as “paltry thing[s]” (9) and “tattered coat[s] upon a stick” (10). However, there is still hope for old men since a journey “To the holy city of Byzantium” (16) will immerse them in a world of timeless art and spirituality. The solution to the speaker’s desire for transcendence is found...

...Looking for shelter I arrived at night, when it was raining. The street was empty; there was not a carriage or light in site. Looking for some shelter I jumped down off my pure black horse and tied it up to the nearest tree and then I started to walk towards the black and rusty gate. I heard a thunder storm heading towards me, so I opened the gate in a hurry. As I did I heard a big long creek. I continued to walk down the muddy and wet path and I saw black crows circling the towers roof tops. I got to the old rotten door and knocked; there was no answer. So I pushed the ancient and rotten door and it swung open. I stepped in side. When I stepped in and a horrible stench came roaring down towards me, I called out “hello” and the only response was the echo of my voice. I started to walk towards the dining area, but on the way I heard a loud bang in a near by corridor. It sounded like something had fallen and smashed then I knew I was not alone. The corridor was completely dark so I collected some dry wood form a near by staircase that had collapsed for a torch, I used what I learnt on the farm to light it. I started to creep towards the corridor with my torch the in my hand, the entrance was made of stone and the half open door that was barely hang on to its hinges looked like it was staring right at me, but I pushed on. As I stepped into the corridor a shiver went down my spine, something was telling me that it wasn’t a good Idea. But something else was louring me in....

...Project : Logistics Control Tower Objective: To design a Logistics Control Tower Solution for E-Commerce Companies Write-up: A control tower is a single command centre for visibility, decision-making, and action, based on real-time data. It’s a powerful cloud service providing a comprehensive unified prospective of your business; top-down to bottom-up. Cross functional team can now rely on a single product to plan, monitor and respond to all business challenges (in this case all issues occur in logistics) quickly, collaboratively enabling you to measure the impact of changes, study response scenario, recalibrate strategies and envision what’s coming down the road, allowing you to see and know it all at the same time. With the help of control tower, Company (and supply chain) will come to be recognized not as a collection of separate functions but as a system in which the flows of information, materials, manpower, capital equipment, and money setup forces that determine the basic tendencies towards growth, fluctuation, and decline. A Supply Chain Control Tower system includes a dedicated team of people responsible for monitoring the alerts of the tower and for taking action when the tower predicts an incident may happen or if an incident already happened. This designated team is delegated the authority to make real time decisions based on the alerts and recommendations reported by the Control Tower. A properly structured Control Tower must be “armed with both the ability to determine...

...I love the C.N. Tower. One reason is I am from Toronto, and I have been up it about twenty times, although it is still fun every time. I find it very cool that this famous tower is in the same city as I was born in, also it is amazing that I can go so high and see so far across my home town. Almost all of my families have been up the tower, and I find that cool because I can talk about it with them when I see them. Every time I go back to Toronto, I always have the C.N. Tower in mind. Every time I fly into Toronto and I can see what was once the world’s tallest tower, looming over the clouds, on top of the world, like it is welcoming me back, that makes me feel at home. And the day when I get to go up the tower is a remarkable experience....

The last reason making the conflict was the role of leader or CEO. He can not remember the values and mission’s company that means he ignore and did not concern the importance of organization culture. This is the result of low level of loyalty making employees had a gossip and nepotism. Moving onto the discussion of stereotype of corporate culture. There are four types that are derived from two related dimensions; task or person (high VS low formalization) and hierarchical or egalitarian (high VS low centralization)(p 238).

...expression brings something to the mind without mentioning it directly. In some of the works of those artists carry the allusion to The Tower of Babel. In Genesis 11, the story of The Tower of Babel is told. In this story the descendants of Noah are brought together to build a tower that reaches the Heavens. The reason they want to build this tower is to have power like God. So while they built the tower, God watched them and began to realize that they can someday be powerful. With that in mind, he went down with the angels to confuse the people in Shinar and separated them all over the world with different languages so they could not understand one another. That would stop them from trying to regain the possibility of having the power like God. It was called Babel because of that reason and this is how our world has come out to have many different languages. Allusions are found in many forms of art. One of the arts that hold allusions to a biblical story is literature. Ray Bradbury published one of his most famous works in 1953, Fahrenheit 451. This novel is science fiction and holds the story of a fireman named Montag in a future like city. His job is to start fires, burn books, not put them out. The setting that Montag is placed in is not allowed to get in contact with books because they hold knowledge and their government believes that it gives power. The main character lives this way too until he meets a teenager names Clarisse and an English Professor named Faber. They show...

...OUTSMARTING GOD: EGYPTIAN SLAVERY AND THE TOWER OF BABEL SHEILA TULLER KEITER The Book of Exodus begins the story of Israel's enslavement in Egypt. A new pharaoh rises to power, one who did not know Joseph (Ex. 1:8). This new pharaoh ushers in a new regime and new policies. He embarks on a national program of enslavement and subjugation. Yet these policies are not as original as one might think, for they are reminiscent of the social-political experiment of another great building society, the people who built the Tower of Babel. The Torah deliberately links these two societies and passes judgment on both. The new pharaoh begins by bringing his cause to the Egyptian people, making the following pitch: 'Look, the Israelite people are much too numerous for us. Come, let us deal shrewdly with them, so that they may not increase; otherwise, in the event of war, they may join our enemies in fighting against us and go up from the land' (Ex. 1:9-10). As presented in the text, the pharaoh's logic is hard to discern. His solution to the problem of Israel's burgeoning population is persecution and enslavement, rather than expulsion or genocide (Ex. 1:11). If they are too many, why not just kill them? Pharaoh does eventually order the killing of all the male babies born to the Hebrews, but only after his first policy prescription results in an Israelite population boom (Ex. 1:12, 16). Furthermore, if the Israelites represent a potential fifth column, why is Pharaoh afraid that they will...

...brand new built. Scott Rice is a company of just seventy-five employees. The employee body is mainly project managers, interior designers, sales man and women, financial accounting, and lead logistic heads that control the warehouse organization. Scott Rice contracts the manual labor portion of the setup, build and other issues regarding licensed individuals (plumbers, electricians, etc.). With the company employing a small staff generates great opportunities within. For example, the company’s largest customer ever is the erection of the Devon Energy Center in downtown Oklahoma City. Scott Rice has to furnish the fifty two story building. As briefed, it will take four hundred and twenty plus semi-truck trailers of furniture to stock the tower with the means to accommodate the two thousand plus staff of Devon Energy. They must work around the clock to finish the task on time. The contractors are able to unload and build three semi-truck loads a shift. This job will generate thirty eight million dollars and this company benefit is that it is a profit sharing company. With a small employee base, that is more money they will receive for their Christmas bonus. Scott Rice has been in business for decades.

...Lord of the Rings The Two Towers As we learn through the first book we come to see that the company of the “Lord of The Rings” goes through hard trials. There is much more to come through their journey though especially in the book of “The Two Towers.” In the book of “The Two Towers” Frodo baggins, and Samwise Gamgee must journey on their own to finish the task that was left for Frodo. While Aragorn II Elessar, Legolas the elf, and Gimli the dwarf search for Peregin Took and Meriadoc Brandybuck, most commonly known as Merry and pippin. It all starts with Aragorn, Legolas, and Gimli searching for Merry and Pippin. The three adventurers go off through the fields tracking down those two hobbits that have been captured by the nasty orcs. The leader of the orcs is none other than the huge appalling Ugluk. He leads his team of orcs, which are known as the Uruk-hai Scouts, to Isengard. That way Saruman could have the hobbits and find out where the ring is. Their plan taking the hobbits to Isengard ended faster than they had expected for they were attacked by Rohirrim. The orcs tried to fight valiantly, but it still ended in ruins for they could not putt up a good fight because they were being shot at by arrows, and their enemy was behind trees on horseback so they couldn’t determine where they were most of the time. While the Orcs were fighting the Rohirrims, Merry and Pippin started to sneak away from the orcs clutches. They successfully escape and begin to head into the “Forrest...

...elements of operations management are incorporated. They include service, flexibility, price and facility location. Service This incorporates the work design of the cooling tower system and the level and quality of service it is capable of offering once purchased. A comparison of the metal in relation to the plastic cooling towers shows that the level of service of the latter is better compared to the metal ones. As shown in the case study the metal cooling towers are negatively affected by water pH, sunlight, pollution, salt air, and harsh process chemicals. This causes corrosion, rust and leakage thus calling for re-welding, patching and coating. The plastic ones are not affected by water pH neither are they affected by harsh weather conditions. They carry a 15 year warranty compared to the one year warranty of the metal cooling towers. Flexibility For effective operations process a product or service should be flexible. This means that it should be able to have the ability to rapidly increase or decrease production levels and change from one product to another. This case study looks at two forms of flexibility, the cooling capacity flexibility and the design flexibility. Metal cooling towers are customized on site and require high cost of labour and materials. However the plastic cooling towers are factory assembled with a 2000 tons capacity. They are thus able to adjust to operational heat load and the outflow changes since they use an extra margin of...

...THE TOWER OF BABEL The Tower of Babel ( oil painting by Pieter Bruegel the Elder, 1563) Courtesy of the Kunsthistorisches Museum, Vienna Genesis 11:1 – 9, the Babylonians wanted to build a tower "with its top in the heavens." Angry at their presumption, God disrupted the enterprise by confusing the languages of the workers so that they could no longer understand each other. The tower was left unfinished and the people dispersed over the face of the earth. The myth may have been inspired by a tower temple located north of the Marduk temple and known as Bab-ilu ("Gate of God"). It was an edifice built after the Flood by the men of Shinar (Babylonia) in their attempt to reach heaven. All the people of the world at that time only spoke a single language. But with Babylonians’ intention to make a name and to avoid dispersal over the earth; they built and constructed a tower which would reach the heaven. However, as God was mad of their presumption, their audacity was punished by confounding their language to prevent them from communicating with one another and they were dispersed throughout the world (Gen 11:1-9). The name Babel (Babylon) derives from the Hebrew word "to confuse". It was Nimrod who led and successfully excited the Babylonians to cause such an offended act and contempt to God. Nimrod, a tyrant, was the grandson of Ham, the son of Noah, a bold man, and of great strength of hand. He persuaded the Babylonians not to ascribe to God, as if...
