Lufenuron is the active ingredient in the veterinary flea control medication Program, and one of the two active ingredients in the flea, heartworm, and anthelmintic medicine milbemycin oxime/lufenuron (Sentinel). Lufenuron is stored in the animal's body fat and transferred to adult fleas through the host's blood when they feed.
Rutherford scattering or Coulomb scattering is the elastic scattering of charged particles by the Coulomb interaction. The paper also initiated the development of the planetary Rutherford model of the atom and eventually the Bohr model. Rutherford scattering is now exploited by the materials science community in an analytical technique called ...
The combination milbemycin oxime/lufenuron (trade names Sentinel Flavor Tabs, by Novartis Animal Health, and Program plus) is a parasite control drug in which the active ingredient, milbemycin oxime, eliminates worms, while a second active ingredient, lufenuron, arrests the development of eggs and larvae, preventing them from maturing and continuing the infestation of an animal.
Historically, the Catholic Church has been a patron of sciences. It has been prolific in the foundation and funding of schools, universities, and hospitals, and many clergy have been active in the sciences. Some historians of science such as Pierre Duhem credit medieval Catholic mathematicians and philosophers such as John Buridan, Nicole ...
The history of science during the Age of Enlightenment traces developments in science and technology during the Age of Reason, when Enlightenment ideas and ideals were being disseminated across Europe and North America. Generally, the period spans from the final days of the 16th- and 17th-century Scientific Revolution until roughly the 19th ...
Benzoylurea. Benzoylureas (BPUs) are chemical derivatives of N -benzoyl- N′ -phenylurea, which are used as insecticides. [1] They do not directly kill the insect, but disrupt moulting and egg hatch, and thus act as insect growth regulators. They act by inhibiting chitin synthase, [2] preventing the formation of chitin in the insect's body.
t. e. An experiment is a procedure carried out to support or refute a hypothesis, or determine the efficacy or likelihood of something previously untried. Experiments provide insight into cause-and-effect by demonstrating what outcome occurs when a particular factor is manipulated.
History of experiments. The history of experimental research is long and varied. Indeed, the definition of an experiment itself has changed in responses to changing norms and practices within particular fields of study. This article documents the history and development of experimental research from its origins in Galileo's study of gravity ...
