Explanation:
Michael E. DeBakey was an American physician, scientist, vascular and cardiac surgeon, and medical educator. He was born on the 7th of September, 1908 in Louisiana, United States of America. Dr Michael held so many high profile position in his 75 years of active service such as becoming the chancellor emeritus of Baylor College of Medicine in Houston, Texas, USA.
Denton A. Cooley was an American heart and cardiothoracic surgeon born on the 22nd of August, 1920 in Texas, United States of America. Dr Cooley was a pioneer surgeon in the field of total artificial heart implantation. He held many notable positions in Texas and as such he was famously known around the world.
In 1951, Dr Denton Cooley was hired by Dr Michael DeBakey to work at the Baylor College of Medicine and The Methodist Hospital, as an associate professor of surgery.
During this time, they both collaborated to improve the national and international healthcare standards by inventing the roller pump used in the heart-lung machine for blood transfusion during a heart surgery.
Hence, the Texas industry which was able to grow as a result of the scientific breakthroughs made by Michael DeBakey and Denton Cooley is medicine.

<h3>
What is a human intervention?</h3>
A person authorized by the Controller can intervene manually by repeatedly evaluating the characteristics, assumptions, and considerations used in the automated decision-making, issuing a different decision, or upholding the prior one. Providing information and energy, physically supporting the robot, and adapting the environment to the robot are all examples of human intervention. Such systems are capable of self-control without human involvement, carry enough fuel for their job, or can use radiant energy from their surroundings. The provision of ecosystem services is one functional necessity that drives human intervention in ecosystems, yet this action frequently has unanticipated negative effects.
