Translation jobs are undertaken by professional translators who are well versed with at least two languages.Translation can work at two levels: inter-state or regional language translation and inter-national or foreign language translation. Some forms of parent involvement with the school such as communications with school, volunteering, attending school events and parent--parent connections appeared to have little effect on student achievement, especially in high school.

Researchers at Harvard University and the California Institute of Technology say the successful effort was a proof of concept for reverse engineering a variety of muscular organs and simple life forms.A description of the research that led to the tissue-engineered jellyfish, dubbed "Medusoid," has been published in Nature Biotechnology.Jellyfish propel themselves through the water by pumping, in an action similar to the way a human heart pumps blood through the body, researchers said.\Engineering Colleges Tamil Nadu"It occurred to me in 2007 that we might have failed to understand the fundamental laws of muscular pumps," Kit Parker, a Harvard professor of bioengineering, said.Best Engineering Colleges"I started looking at marine organisms that pump to survive. Then I saw a jellyfish at the New England Aquarium and I immediately noted both similarities and differences between how the jellyfish and the human heart pump."Researchers used a sheet of cultured rat heart muscle tissue that would contract when electrically stimulated in a liquid environment to create an ersatz jellyfish.The artificial construct was placed in container of ocean-like salt water and shocked into swimming with synchronized muscle contractions that mimic those of real jellyfish.
