Packet filters act by inspecting the ''packets'' which are transferred between computers on the Internet. If a packet does not match the packet filter's set of filtering rules, the packet filter will drop (silently discard) the packet or reject it (discard it, and send ''error responses'' to the source). Conversely, if the packet matches one or more of the programmed filters, the packet is allowed to pass. This type of packet filtering pays no attention to whether a packet is part of an existing stream of traffic (i.e. it stores no information on connection ''state''). Instead, it filters each packet based only on information contained in the packet itself (most commonly using a combination of the packet's source and destination address, its protocol, and, for TCP and UDP traffic, the port number). TCP and UDP protocols constitute most communication over the Internet, and because TCP and UDP traffic by convention uses well known ports for particular types of traffic, a ''stateless'' packet filter can distinguish between, and thus control, those types of traffic (such as web browsing, remote printing, email transmission, file transfer), unless the machines on each side of the packet filter are both using the same non-standard ports.

Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O ) at increased partial pressures. It is also known as oxygen toxicity syndrome, oxygen intoxication, and oxygen poisoning. Historically, the central nervous system condition was called the Paul Bert effect, and the pulmonary condition the Lorrain Smith effect, after the researchers who pioneered its discovery and description in the late 19th century. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs and eyes. Oxygen toxicity is a concern for underwater divers, those on high concentrations of supplemental oxygen (particularly premature babies), and those undergoing hyperbaric oxygen therapy.

can you be killed by too much oxygen?

A: yes

By March 2015, after not playing any matches, India reached their lowest FIFA ranking position of 173. A couple months prior, Stephen Constantine was re-hired as the head coach after first leading India more than a decade before. Constantine's first major assignment back as the India head coach were the 2018 FIFA World Cup qualifiers. After making it through the first round of qualifiers, India crashed out during the second round, losing seven of their eight matches and thus, once again, failed to qualify for the World Cup.

is india qualified in fifa world cup 2018?

A: no

On September 10, 2014, a third Jump Street film was confirmed. Channing Tatum has yet to sign on to the project. Tatum stated, ''I don't know if that joke works three times, so we'll see.'' On August 7, 2015, it was revealed that Lord and Miller will not direct the film, but instead write and produce. A first draft of the film's script has been completed. On December 10, 2014, it was revealed that Sony was planning a crossover between Men in Black and Jump Street. The news was leaked after Sony's system was hacked and then confirmed by the directors of the films, Chris Miller and Phil Lord, during an interview about it. James Bobin was announced as the director in January 2016. The title of the crossover was later revealed to be MIB 23, and the crossover would replace a 23 Jump Street film. By August 2016, Jonah Hill considered that MIB 23 would be hard to make, as ''They're trying to make all the deals, but it's kind of impossible with all the Men in Black stuff'', and ''it's hard to maintain that joke when it's so high stakes'' given the film would get too close to the sort of remake, sequel and reboot the previous films mocked. Still, Hill hoped to make a third Jump Street. In December 2016 it was revealed that Rodney Rothman had written a script for the film, and that Bobin is still attached as director for the movie.

is there going to be a 3rd 21 jump street?
