In the event of a radiation emergency, the first thing to figure out is if you are contaminated. If you have radioactive materials on or inside your body, you're contaminated. Contamination can quickly spread -- you'll shed external contaminants as you move about and release bodily fluids....
But before we start sending children on an intergalactic school bus ride, we must figure out new ways to accomplish everyday tasks in space, like growing food. International organizations are devoting time and resources to the development of sustaining human life beyond Earth. Some of the space ...
More about me...I've built 5 ships from scratch and used to run a small business selling supplies and building cannons for the ships. I made several design improvements to the cannon, but cost of having parts cnc'd drove the prices up to high. I sold my business to strike models http...
Figure 7 Volume-rendered close-up images (a,b) of a maleDiaphorina citrifeeding on an orange seedling tree leaf (c) in two perspective views: frontal (a) right-frontal (b). In (a) the virtual box-cut made to visualize the stylets and salivary sheaths inside the leaf and vascular bundl...
Click on the left and right arrow buttons within that box to see how the electron orbitals and sub-orbitals are filled as you step through the periodic table.] As you can see, the general order for filling the electron orbitals follows a sequence since the energy level for each orbital ...
or six electrons in its outermost orbital. You can also figure out how many electrons are in its first, second and third orbitals: The first orbital can hold a maximum of two electrons, while the second has four suborbitals and so can hold a total of eight electrons. The third shell of...
When an electron drops to a lower orbital, it needs to release some energy -- it releases the extra energy in the form of a photon. The energy level of the photon depends on how far the electron dropped between orbitals. (See this page for a detailed description of this process.) When...
Figure 3. Box plot presenting FCM cell counts of treated and untreated (control) cultures. Treated groups include cell counts of undiluted, 1:50 diluted and 1:500 diluted cultures. StT = Standard Treatment; StT+C = Standard Treatment + Chloramphenicol; StT+U = Standard Treatment + Ultrasonicati...
As single-electron wave equation with stationary binding potential leads to discrete energy eigenvalues, the atomic SCF conception reduces the multi-electron atom problem to the determination of its electronic structure—single-electron atomic orbitals (AO) and corresponding electron energy levels. Thus, ...
In silico structural models are used to simulate molecular interactions, especially with potential aggregation inhibitors. In a recent study, molecular simulations, molecular docking, and fragment molecular orbital calculations were performed to observe the interaction of tau with curcumin derivatives [89]....
