In batch type-rock-N-Roll type Rotational Moulding machines, frame of the machine is turned in a primary axis while mould is rotated in secondary axis. As rotational moulding does not involve any injection pressure and high shear rates, this process offers certain basic advantages over other processes and techniques of plastic processing. a) Complex parts can be moulded without need for post-assembly.

b) Low machinery cost relative to production capacity. c) Double walled items can be produced. d) Ease of colour and material change. e) Multiple product and multi colours can be moulded at the same time f) Minimum wastages. g) High production capacity on selected parts. h) Production design freedom. These tanks keep water clean, odour free and maintain the quality of water stores intact. These tanks are economical, practical and hygienic alternative of storing potable water in single or multi storeyed residential units, industrial set-ups, commercial establishments and sites everywhere under the sun.

Apc - Present Trends and Future Development

...APC - PRESENT TRENDS AND FUTURE DEVELOPMENT INTRODUCTION The fundamental problem of managing military research and development is that uncertainty about the enemy and the costs and benefits on new technologies make it impossible to identify the single best route to innovation. Stephen P Rosen 1. Stephen Rosen’s statement identifies one of the most challenging problems facing political and military leaders today. In an era of uncertainty, which includes a diversity of potential threats and military operations, what is the “best route” in the area of military innovation to translate limited research and development resources into capabilities to deal with current or potential threats and its allies? By the time World War I ended military theorists around the world had learned from several rude surprises. First of all, horse-drawn and foot transport really wasn't good enough in the modern world. They didn't exactly get rid of the horse but horses were extremely vulnerable to fire, and the mud characteristic of trench warfare slowed them down a bit. Men were better in mud, but not much, and could not march quickly enough. The imperatives of battle were such that soldiers had to be able to move in almost all conditions, and if breakthroughs were to be exploited, they had to move fast. 2. The realities of trench warfare came as a rude shock to officers in World War I. Machine guns, barbed wire and trenches...

...was around them. The industry began investigations to discover what really took place that day in order to prevent such an event from occurring again. The Union Carbide plant produced a wide range of pesticides that were very critical to the economy of India. For the production of these products, a number of steps were required. The first step was the reaction of carbon monoxide with chlorine to produce intermediate phosgene. The second step of the process mixes monomethylamine with phosgene to yield MIC. The third step of the process causes alpha napthol to react with MIC to produce carbaryl. Each of the chemicals used in this process is hazardous and requires specific safety handling procedures (Safety 49).Union Carbide had thousands of tanks that they used to create the...

Happy Birthday, 1951

...decides to take the boy to a green and living place outside the devastated city. In addition, the man creates a cart for the boy, which the boy rather sees as a tank. On their way to the place, the boy spots an old, rusty tank, which fascinates the boy. The man becomes more and more irritated by the boy’s admiration of things connected to war, which culminates in the man becoming angry with the boy. When the elderly man wakes up after a nap, the boy is gone. The man finds him saying ”Gotcha!” while seated in the tank’s turret pointing towards him. 2: Characterization The young boy was born in the latter half of the Second World War. We can extract this piece of information because of the short story’s title (1951), and because the boy has not gotten any birthday presents in the first six years of his life, which means that the boy turns 7 years in the short story. The boy’s nationality, name and birthdate are also unknown. The boy’s mother was a refugee, who probably delivered her baby to the old man because she feared for her life. The young boy has lived his whole life in a cellar in a shattered city. Therefore he cannot remember much if anything nothing from the war. This is why he does not have the same view on soldiers and tanks as the old man, who takes care of him. The boy admires the soldiers and the tanks, like many male children do at that age, and he has examined them closely, ””Black and red is the engineers,” interrupted the boy seriously...” (p. 3, ll 88-90)...

The Somme

...and that everything was fine from living conditions to casualties. For the first time the people of Britain are witnessing the true extent of war. The camera men would take pictures of the aid posts as well as the trenches which for families and new enlists was a terrible sight and worried the nation. The photographers were wary at the time that maybe it could cause a big scene back in Britain. The generals said that the push towards the line led to so many disappointments but yet no one stopped the tactics. There was said to be the first use of tanks on the Somme which was a turning point tin the tactics and the push became easier and was the success and edge needed for no mans land. Letters and diaries from the soldiers showed the boost in moral with the tanks and how Germans were terrified of these machines of the fields and that soldiers had stepped up there fighting and German soldiers lost moral. The book also mentions the tanks were brilliant for getting across barbed wire and shell holes in the field and the protection it gave soldiers, tracks built for the worst terrain.

Case of Gm (Non-Market Environment)

...root cause is that the GM company has a unreasonable design of their gas tank on the collisions GM C/K pickups, the report shows that this pickups’ gas tank was too close with the bumper, it only 25 centimeters long. This is dangerous because that will cause explosions if there is any strike. A safety design should be place the gas tank on the top of axle or add on a shield between the gas tank and bumper. Further, the report also shows that the gas tank design was used for trucks manufactured between 1979 and 1987, and the fact is GM knows about their design problem but take no measure to fix or recall their cars because that will cause more cost. At the Moseley case happens, there are at least 130 other lawsuits involving the design of the gas tank GM need to faced. So the major issue of this case in this point is that whether the gas tank design and placement were defective and because that explosion case after their pickup was struck on the side by another vehicle. And those assumptions were proved by the GM engineer who is testified that GM company hidden the knowledge of this dangerous safety defect, but GM try to block his testimony because they had known for years and refused correct it for fear of alerting the public. Moreover, the provided videotapes of GM’s own crash tests between 1981 and 1983 showed that it’s truly dangerous when the pickup was stuck on the side by another vehicle its gas tank broke open. b.

... 1951” “Happy Birthday, 1951”, is a short story written by Kurt Vonnegut, 2008, which begins in media res. The story is about a young boy and an old man, who is not the father of the boy.

That 2000 Yard Stare Analysis

...including soldier’s heart, irritable heart, traumatic neuroses, shell shock, war hysteria, combat stress reaction, Vietnam veterans syndrome, and fright neuroses, today it is called combat post-traumatic stress disorder or PTSD. Personally, I have been diagnosed with combat PTSD and I have professionally treated other victims of combat PTSD, making it a very important subject for me. In the image, we see an expressionless soldier staring outward wide-eyed towards the viewer. His eyes are dark and glossy. He dons a dented helmet and torn cloths. His appearance gives the idea of filth and exhaustion. Behind him are three soldiers, one collapsed in a heap empty handed and in torn clothing. The other two are more remote, conversing in the back. The tank has its cannon turned and elevated a sign that it either has fired or will shortly. Behind the men, a tropical forest can be seen charred and smoking. No grass or low hanging greenery can be seen, only splintered wood and ash. Even farther back, a darkened mountain ridge comes into view; it appears barren in the distance. High above the scene two planes can be seen flying towards the mountains. The closest warfighter’s eyes are unfocused and bloodshot. The sunken orbs altogether devoid of emotion and hollow. The pupils dilated beyond what seems possible. Dark rings sit under his eyes, the reward for so many sleepless nights. His cheeks are sunken and his collarbones stick out ghoulishly. He displays no animosity, despair, or agony; yet the...
