2. Lufenuron - Wikipedia

   en.wikipedia.org/wiki/Lufenuron

   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. Adult fleas ...

3. Rutherford scattering experiments - Wikipedia

   en.wikipedia.org/wiki/Rutherford_scattering...

   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 ...

4. Milbemycin oxime/lufenuron - Wikipedia

   en.wikipedia.org/wiki/Milbemycin_oxime/lufenuron

   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.

5. Benzoylurea - Wikipedia

   en.wikipedia.org/wiki/Benzoylurea

   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.

6. Magdeburg hemispheres - Wikipedia

   en.wikipedia.org/wiki/Magdeburg_hemispheres

   Small 4 in. hemispheres, 1870s. The Magdeburg hemispheres are a pair of large copper hemispheres with mating rims that were used in a famous 1654 experiment to demonstrate the power of atmospheric pressure. When the rims were sealed with grease and the air was pumped out, the sphere contained a vacuum and could not be pulled apart by teams of ...

7. Wheeler's delayed-choice experiment - Wikipedia

   en.wikipedia.org/wiki/Wheeler's_delayed-choice...

   Introduction. " Wheeler's delayed-choice experiment " refers to a series of thought experiments in quantum physics, the first being proposed by him in 1978. Another prominent version was proposed in 1983. All of these experiments try to get at the same fundamental issues in quantum physics. Many of them are discussed in Wheeler's 1978 article ...

8. Gene knockdown - Wikipedia

   en.wikipedia.org/wiki/Gene_knockdown

   Gene knockdown. Gene knockdown is an experimental technique by which the expression of one or more of an organism 's genes is reduced. The reduction can occur either through genetic modification or by treatment with a reagent such as a short DNA or RNA oligonucleotide that has a sequence complementary to either gene or an mRNA transcript.

9. Optogenetics - Wikipedia

   en.wikipedia.org/wiki/Optogenetics

   Optogenetics. Optogenetics is a biological technique to control the activity of neurons or other cell types with light. This is achieved by expression of light-sensitive ion channels, pumps or enzymes specifically in the target cells. On the level of individual cells, light-activated enzymes and transcription factors allow precise control of ...
