Article: Vaccines rely on immune modulation or augmentation. Vaccination either excites or reinforces the immune competence of a host to ward off infection, leading to the activation of macrophages, the production of antibodies, inflammation, and other classic immune reactions. Antibacterial vaccines have been responsible for a drastic reduction in global bacterial diseases. Vaccines made from attenuated whole cells or lysates have been replaced largely by less reactogenic, cell-free vaccines consisting of purified components, including capsular polysaccharides and their conjugates, to protein carriers, as well as inactivated toxins (toxoids) and proteins.

Question: What type of vaccines have saved millions of lives?
Ans: Antibacterial vaccines

Article: Everton have had many other nicknames over the years. When the black kit was worn Everton were nicknamed "The Black Watch", after the famous army regiment. Since going blue in 1901, Everton have been given the simple nickname "The Blues". Everton's attractive style of play led to Steve Bloomer calling the team "scientific" in 1928, which is thought to have inspired the nickname "The School of Science". The battling 1995 FA Cup winning side were known as "The Dogs of War". When David Moyes arrived as manager he proclaimed Everton as "The People's Club", which has been adopted as a semi-official club nickname.

Question: What was Everton Football Club called after winning the 1995 FA Cup?
Ans: The Dogs of War

Article: In Ancient Rome, Tyrian purple was the color of the Emperor, but red had an important religious symbolism. Romans wore togas with red stripes on holidays, and the bride at a wedding wore a red shawl, called a flammeum. Red was used to color statues and the skin of gladiators. Red was also the color associated with army; Roman soldiers wore red tunics, and officers wore a cloak called a paludamentum which, depending upon the quality of the dye, could be crimson, scarlet or purple. In Roman mythology red is associated with the god of war, Mars. The vexilloid of the Roman Empire had a red background with the letters SPQR in gold. A Roman general receiving a triumph had his entire body painted red in honor of his achievement.

Question: What color was correlated with the Army in ancient Rome?
Ans: Red

Article: This is fortunate, since antennas at lower frequencies which are not rather large (a good fraction of a wavelength in size) are inevitably inefficient (due to the small radiation resistance Rr of small antennas). Most AM broadcast radios (except for car radios) take advantage of this principle by including a small loop antenna for reception which has an extremely poor efficiency. Using such an inefficient antenna at this low frequency (5301650 kHz) thus has little effect on the receiver's net performance, but simply requires greater amplification by the receiver's electronics. Contrast this tiny component to the massive and very tall towers used at AM broadcast stations for transmitting at the very same frequency, where every percentage point of reduced antenna efficiency entails a substantial cost.

Question: What is added to to increase ability for reception?
Ans:
small loop antenna
