Student A:Passage: Texas has no laws regarding possession of any firearm regardless of age, without felony convictions; all existing restrictions in State law mirror Federal law. A person of any age, except certain Felons, can possess a firearm such as at a firing range. Texas and Federal law only regulate the ownership of all firearms to 18 years of age or older, and regulate the transfer of handguns to 21 years or older by FFL dealers. However, a private citizen may sell, gift, lease etc. a handgun to anyone over 18 who is not Felon. NFA weapons are also only subject to Federal restrictions; no State regulations exist. Municipal and county ordinances on possession and carry are generally overridden (preempted) due to the wording of the Texas Constitution, which gives the Texas Legislature (and it alone) the power to "regulate the wearing of arms, with a view to prevent crime". Penal Code Section 1.08 also prohibits local jurisdictions from enacting or enforcing any law that conflicts with State statute. Local ordinances restricting discharge of a firearm are generally allowed as State law has little or no specification thereof, but such restrictions do not preempt State law concerning justification of use of force and deadly force.

Student A:He next experimented with a high-pressure hydrogen jet by which low temperatures were realised through the Joule -- Thomson effect, and the successful results he obtained led him to build at the Royal Institution a large regenerative cooling refrigerating machine. Using this machine in 1898, liquid hydrogen was collected for the first time, solid hydrogen following in 1899. He tried to liquefy the last remaining gas, helium, which condenses into a liquid at 268.9 C, but owing to a number of factors, including a short supply of helium, Dewar was preceded by Heike Kamerlingh Onnes as the first person to produce liquid helium, in 1908. Onnes would later be awarded the Nobel Prize in Physics for his research into the properties of matter at low temperatures -- Dewar was nominated several times, but never succeeded in winning the Nobel Prize.
