Nav'
The Nawie or Nawki in Polish, the Mavka (Navka, Nyavka, Zalozhnі mertsі) in Ukrainian, or simply Nav' in other Slavic languages are ghosts or the souls of persons that had met a tragic or premature death, particularly unchristened babies. In Slavic mythology, Nawie exist in the underworld called Nawia.
In Ukrainian mythology, Mavka is a type of mermaids with long flaxen hair. The name Mavka derives from Nav’ (Navka), which means "the embodiment of death." Mavky (plural) do not have a full body, have no reflection in water, do not cast shadows, and have no back, and so their insides can be seen.
The traditional view is that Mavky live in the woods of Galicia (Ukraine) and the Carpathians. Mavky symbolize the souls of children who were born dead or died unbaptized. They often appear in the form of beautiful young girls dancing and singing to lure young men into the woods where they would tickle them to death and chop their heads off.
To save a baby's soul, one had to throw up a kerchief during Trinity holidays, say a name and add "I baptize you". A rescued soul would then go to heaven. If a soul lived up to seven years and did not go to heaven, a baby would turn into a mermaid or a Mavka and would haunt people.

Nav1.7
Nav1.7 is a sodium ion channel that in humans is encoded by the SCN9A gene. It is usually expressed at high levels in two types of neurons, the nociceptive (pain) neurons at dorsal root ganglion (DRG) and trigeminal ganglion, and sympathetic ganglion neurons, which are part of the autonomic (involuntary) nervous system.
Function
Nav1.7 is a voltage-gated sodium channel and plays a critical role in the generation and conduction of action potentials and is thus important for electrical signaling by most excitable cells. Nav1.7 is present at the endings of pain-sensing nerves, the nociceptors, close to the region where the impulse is initiated. Stimulation of the nociceptor nerve endings produces "generator potentials", which are small changes in the voltage across the neuronal membranes. The Nav1.7 channel amplifies these membrane depolarizations, and when the membrane potential difference reaches a specific threshold, the neuron fires. In sensory neurons, multiple voltage-dependent sodium currents can be differentiated by their voltage dependence and by sensitivity to the voltage-gated sodium-channel blocker tetrodotoxin. The Nav1.7 channel produces a rapidly activating and inactivating current which is sensitive to the level of tetrodotoxin. Nav1.7 is important in the early phases of neuronal electrogenesis. Nav1.7 activity consists of a slow transition of the channel into an inactive state when it is depolarized, even to a minor degree. This property allows these channels to remain available for activation with even small or slowly developing depolarizations. Stimulation of the nociceptor nerve endings produces "generator potentials", small changes in the voltage across the neuronal membranes. This brings neurons to a voltage that stimulate Nav1.8, which has a more depolarized activation threshold that produces most of the transmembrane current responsible for the depolarizing phase of action potentials.
Birdy (bicycle)
The Birdy is a folding bicycle designed by Riese und Müller in Germany and produced by Pacific Cycles in Taiwan. As of 2010 over 100,000 had been sold. Three distinct models have been marketed, the third (Mk3) sold from July 2015.
First released in 1995, it was the first fully suspended folding bike. The ride is regarded by some as more sporty than the Brompton, thanks in part to a stiff single-piece aluminium frame with road bike rider geometry and no hinge. Some prefer its stiff suspended ride and rapid acceleration to that of a full-sized bike.
Specifications
Markus Riese had the basic idea for the Birdy in 1992. The first prototype was quickly welded together from two old bicycles in his parent's garage (photos and German article here). After a year, Markus Riese and Heiko Muller built a prototype out of aluminium and won the “Hessian Innovation Prize”. The prototype was shown at two trade shows, Intercycle in Cologne and Eurobike in Friedrichshafen, and caused a stir. The first Birdy bikes were sold in 1995 as a 'de luxe' folder, the first with full suspension. It had a high price tag, usually over US$1,000.
Par (score)
In golf, par is the pre-determined number of strokes that a scratch (or 0 handicap) golfer should require to complete a hole, a round (the sum of the pars of the played holes), or a tournament (the sum of the pars of each round). Pars are the central component of stroke play, the most common kind of play in professional golf tournaments. The term is also used in golf-like sports such as disc golf with the same meaning.
The length of each hole from the tee placement to the pin determines par values for each hole primarily but not exclusively. Almost invariably, holes are assigned par values between three and five strokes. For a casual player from the middle tees, a par-three hole will be 100–250 yards (90–230 m) from the tee to the pin. Par-four holes are 250–470 yards (230–430 m), although tournament players will often encounter par-four holes 500 yards (460 m) or more, as it is not uncommon for short par-five holes for normal play to be turned into par-four holes in championship play. Par-five holes are typically 470–600 yards (430–550 m), but in the modern game holes of over 600 yards are becoming more common in championship play. Other relevant factors in setting the par for the hole include the terrain and obstacles (such as trees, water hazards, hills, or buildings) that may require a golfer to take more (or fewer) shots. Some golf courses feature par-sixes and, very rarely, par-sevens, although the latter are not recognised by the United States Golf Association.
