Halting the Ocean Conveyor Belt Theory

For decades scientists have believed that Earth’s ocean currents worked like a giant conveyor belt, continuously transporting cold waters towards the equator and warmer waters towards the poles. This generally held model was driven by changes in temperature and salinity of the surface waters at high latitudes.
But in a paper in the June 18 issue of the journal Science Duke University oceanographer Susan Lozier, professor of physical oceanography and chair of the Division of Earth and Ocean Sciences at Duke University’s Nicholas School of the Environment, has suggested that it is time to rethink the conveyor belt model.
“The old model is no longer valid for the ocean’s overturning, not because it’s a gross simplification, but because it ignores crucial elements such as eddies and the wind field,” she says. “The concept of a conveyor belt for the overturning was developed decades ago, before oceanographers had measured the eddy field of the ocean and before they understood how energy from the wind impacts the overturning.”
“It is important to understand that there is clear and convincing evidence that the ocean waters overturn and that this overturning impact’s the Earth’s climate,” she adds. “Recent studies, however, have cast doubt on our ability to describe this overturning as a conveyor belt. From these studies we now understand that the overturning waters are not restricted to narrow boundary currents, that the overturning may vary from one ocean basin to the next and that the winds may create variability in the amount of water that overturns and in the pathways for the upper and lower limbs of the overturning.”
Lozier’s article in Science also looks at what we still do not know about the ocean’s overturning and how the overturning might change. Lozier will be leading a new international research program aiming to address the question of climate effects.
“Basically, our ability to refine our understanding of the ocean’s overturning stems in large part from our ever increasing ability to measure the ocean at finer and finer scales and at depths previously unmeasured,” she says. “Because the ocean waters are corrosive, at high pressure and generally inaccessible, the ocean has historically been a sparsely observed system. Recent technological advances are rapidly expanding the ocean’s observational database and with it, our understanding of ocean circulation.”

Promoting education negotiable securities: Double arrow stock reasonable value sector 23.92-28.08 Yuan

examination commentaries 　　
China becomes the global biggest  conveyor belt  production and marketing country: during 2003-2008 years the Chinese conveyor belt output compound rate of increment surpasses 20%,2008 years to amount to 230,000,000 square meters, occupies the global market about 3/1. Shifts gradually along with the European and American countries conveyor belt profession to China, in the future the Domestic enterprise will welcome the high speed development opportunity.
Corporation is the domestic high force conveyor belts  commands troops the enterprise: The double arrow stock is domestic concentrates the rubber conveyor belt research and development, the production and the sale commands troops the enterprise. The main product for each kind of high strength conveyor belt, the product widely applies in profession domains and so on steel and iron, cement, coal, electric power and harbor. Company in 2009 business income 627,000,000 Yuan, net profit 0.61 Yuan, domestic market percentage of 10.5%.
 Corporation holds the superiority in the high-end domain: The conveyor belt profession subdivides the market competition pattern to split up gradually, the company and so in the high-tech product holds the superiority in the coal mine shaft being flame-resistant conveyor belt and the tubular Oil Resistant Conveyor Belt.

the overseas market makes the breakthrough hopefully: The company product performance-to-price ratio already had the international competitiveness, along with Australian, the South America mining industry’s rapidly expand, the company is hopeful is developing the overseas new customer aspect to make the breakthrough.

 solicits throws the project to further promote the company competitive power: The double arrow stock this time plans to distribute 20,000,000, will raise the fund to use in 11,000,000 square meter high force conveyor belt items of basic construction. Will solicit throws the project to cause the company to produce can obtain the promotion, the product mix can further optimize, will promote company’s market competitiveness comprehensively.
suggestion inquiry sector 21.53-25.72 Yuan: Estimated that the company 2010-2012 years spread thin EPS are completely 1.04 Yuan, 1.47 Yuan and 1.82 Yuan. Considered company’s competitive advantage and the profession broad prospects for development, the achievement 23-27 time of market profits give the company according to 2010 the estimate value, the reasonable value sector is 23.92-28.08 Yuan.
suggestion inquiry sector 21.53-25.72 Yuan.
risk prompt: The product recession in demand brings risk, raw material price fluctuations risk, exchange rate risk

Food conveyor belt maintenance

Food Conveyor System  maintenance
Each belt has its own maintenance, food conveyor belt maintenance of the following points:
    1, food conveyor belt in the transport and storage, should be kept clean to avoid direct sunlight or rain and snow soaked pouring, to prevent acid, alkali, oils, organic solvents and Oil Resistant Conveyor Belt

 other materials in contact and one meter away from the heating device.
    2, storage warehouse, when the temperature should remain at 18-40 ℃, relative humidity should remain at 50 – 80% between.
    3, storage period, the conveyor belt to be placed into a roll, Steel Mesh Conveyor Belt not fold, place to be on a quarterly basis during the flip once.
    4, different types, specifications layers of the conveyor belt should not be together, then use the connector preferably bonding method.
   Austrian Yu improve food conveyor, acid and alkali conveyor belt, coal conveyor, conveyor belt tire maintenance methods.
