High temperature working parts

Rice is the most widely consumed staple food in India and a large part of the world's human population, especially in Asia. In this review we discussed about the Morphological and molecular mechanisms for drought tolerance in rice. Rice requires high temperature above 200C but not more than 35 to 400C. The lots of work have been done in this area to find out the cultivars, resistance to drought.

In this study, high temperature oxidation-resistant NiCr/Al duplex coatings on carbon steel substrate have been fabricated by electrical wire arc-spraying process. The oxidation resistance properties of NiCr/Al duplex coating system have been evaluated at 800 °C during retention times of 1.5, 3.0, 4.5 and 6.0 hours. The morphology and chemical composition of their cross-sectional structures were investigated using scanning electron microscopy coupled with energy dispersive spectroscopy (SEM/EDS).

The rapid increase in emissions of major greenhouse gases such as CO2 and CH4 in the last decade has seriously affected the climate change and the living environment in the world in general and in Vietnam in particular. In addition, the demand for effective use of CO2 - rich natural gas has promoted studies to find new, highly active and stable catalysts for the methane reforming process. NiO has proven to be the most suitable catalyst for industrial application of the reforming process.

Nowadays, there are many kinds of soldering irons such as: pulse soldering iron, baking soldering iron, but these machines are not stable in temperature and are not highly accurate during working time. Besides those, they cannot be controlled in temperature for different applications. To overcome the disadvantages of the old kinds of soldering irons, the soldering station, which can change the temperature and track and stabilize around the setting points, has been discovered in this paper.

As output decreased the unemployment rate increased, rising from 4.6% in 2007 to a peak of 10.1% in October 2009, and remaining only slightly below that high into 2011. The U.S. unemployment rate has not been at this level since 1982, when in the aftermath of the 1981 recession it reached 10.8%, the highest rate of the post-war period. (During the Great Depression the unemployment rate reached 25%.) This rise in the unemployment rate translates to about 7 million persons put out of work during the recession. Another 8.
