The most popular user-authentication method is the password.Many authentication systems try to enhance their security by enforcing a strong password policy, and by using the password as the first factor, something you know, with the second factor being something you have.However, a strong password policy and a multi-factor authentication system can
This paper reports on the design of fabrication and testing of a machine for cottage level production of pellets from cassava mash.The pelletizer consists of a barreled screw auger which compresses cassava mash against perforated end plate, through which the pellets are pelletized.The result derived from the calculated Bowls design parameters (shaf
Spacecraft flybys provide access to the chemical composition of the gaseous envelope of the planetary object.Typical relative encounter velocities range from km/s to tens of km/s in flybys.For speeds exceeding about 5 km/s, modern mass spectrometers analyzing the rapidly encountering gas suffer from intrinsic hypervelocity impact-induced fragmentat
Diatoms rapidly THYROID SUPPORT release extracellular oxylipins (oxygenated lipids) including polyunsaturated aldehydes in response to herbivory and other stresses.Oxylipins have several defense-related activities including inhibition of reproduction in herbivores and signaling to distant diatoms.Physiological changes in diatoms exposed to varying
