Jason Box at the derelict DYE-2 place May 2003. Picture: M. McCallisterSix months in, we've embossed $90,000 and attached to a study cause. We’re charging up our spectrometer and collecting an ice gist recitation. We've by now engaged commercial-grade aviation and are aim to Greenland this 24 of June.From Greenland’s glide, it’s not a myopic fledge to the ice canvas southerly topographical separate at an aggrandizement of 8000 feet (2440 meters). Reacting to a financing restraint, we’ve deserted the more expensive use of a ski-equipped plane. We’ve Read more [...]
"Helmet slowdown» (Deceleration helmet) - German designer Lorenz invention Potthasta. The man, who had put on the head of this construction, we can experiment with their sense of time, watching everything in slow motion, or, conversely, an accelerated mode.Helmet device is no less interesting than his round and shiny appearance. Inside his bicycle helmet, to which are attached the front glasses with displays, and the top is a netbook, and even found a place for an external battery. Front in the helmet display to an observer can see the same as the test subject.To the device attached Read more [...]
Using sleds, under favorable conditions, can go through the plains and mountain valleys sloping distance much greater than if the pull weight on your back.
Hoping for deep powder snow, sleds have to increase the height to 30 cm (the limit), track width of this should fit the width of trails. But with such ratios size sleigh obtained unstable: they are often on the go over on its side. At these sleds need to have the goods as low as possible (thin layer). The load with the fit, the sledge has to make long - 2 meters or more.
Increase stability by reducing sleds reach Read more [...]
with a rectangular groove on the rod for bait
Two sticks stuck in the ground and keep your knots crossbar for which a rectangular groove engages vertical rod with bait (a rope attached to a shrinking). Attached to the rod and bait loop. Put the trap in the open for catching small predators and pigs.
Tents of the most common Gable tents in a "house" (Fig. 2). The most preferred of industrial - "pamirka." She often floor and roof are made of silver rubberized percale and therefore it is also called "silver." Height "pamirki" - 1.2 m, the net weight (without racks and pegs) - about 3 kg. It easily fit three people for the night, and if necessary - and four. Another suitable type of tent - "poludatka." It is slightly higher (1.5 m) and a little wider. But usually made of canvas and therefore weighs between 5 kg b. To it must be done awning Read more [...]

Chemicals or factors that increase the activity of enzymes, regardless of ions, temperature, pressure and concentration of the substrate, called enzyme activators and reducing their activity - inhibitors or inactivators. Activator can operate in one of two ways: either it increases the number of "active groups" enzyme (true activator) Or counteracts inhibitors (antiingibitor).
Activators play an important role in the treatment of enzymes. Their effect is due to the fact that they are attached to the active site of a group of apoenzyme, coenzyme, or both. This connection may be reversible Read more [...]
Fascia of the head mainly developed in the masticatory muscles.
Temporal fascia (f. temporalis) - Very solid and sturdy piece that covers the temporal muscle. Originates from the periosteum on linea temporalis superior, the bottom forks and two plates attached to the inner and outer surfaces of the zygomatic arch.
Fascia masseter muscle and parotid gland (f. parotideomasseterica) covers the same name of the muscle to form a bed for the parotid gland. Fascia extends up to the zygomatic process, in the back is attached to the mastoid process, goes to the fascia sternocleidomastoid muscle and then Read more [...]

The outer surface of the bone, except for the joint surfaces and the attachment points of tendons and ligaments, covered periosteum (periosteum), which is a thin (100-200 microns) connective plate. Periosteum is firmly attached to the bone due to the presence of connective tissue fibers, perpendicular to penetrating the compact substance bone. Periosteum consists of two layers: the outer - and inner adventitia - fiber. In the adventitia of the periosteum has a lot of collagen fibers, among which are the nerves, plexus of small arteries, veins and lymphatic vessels. Blood vessels in the periosteum Read more [...]
External and internal intercostal muscles (Mm. intercostales externi et interni) (Fig. 165). Extraocular muscles develop from the outer muscle of the plate, which covers an area from the heads of ribs to rib cartilage, and internal muscles are laid out inside the muscle plate lying between the rib and the edge angle of the sternum. Lots of intercostal spaces, with one layer of muscles, ligaments filled intercostals.
Outdoor intercostal muscles start at the bottom of the overlying rib fibers go down and down and attached to the top of the underlying ribs.
Internal intercostal muscles fibers have Read more [...]
Ossicles (Ossicula auditus) include hammer (Malleus), anvil (incus) and stirrup (stapes) (Fig. 557).557. Ossicles, right.

Subcutaneous muscle (M. platysma) lives up to its name. Represents a broad, often loosened thin muscle flap (Fig. 179) located on the anterior side of the neck. Begins in the subcutaneous tissue of the f. pectoralis et deltoidea at II-III edges and attaches to the base of the body of the mandible and f. parotideomasseterica. Part of the beams is woven into the circular muscle of the mouth.

Ectopectoralis (M. pectoralis major) is a broad irregular square plate is located on the front of the chest (Figure 166). It originates from the clavicle, sternum and aponeurosis of external oblique abdominal muscles (partes clavicularis, sternalis et abdominalis). All three parts of the muscles are connected by a shoulder bone in the tendon that attaches to the crista tuberculi majoris. Top clavicular edge of the pectoral muscle and the anterior edge of the deltoid muscle limit groove (sulcus deltoideopectoralis), which is the final part of the saphenous vein (v. cephalica) with upper extremity.

In polar waters are found grayling, trout, sturgeon, ling, chum salmon, white salmon, Kunzhi and other fish species. Only at high-latitude lakes islands usually poor fish. Fish can spear, catch nets, rods, hands or turn off rocks, sticks. The simplest form of a hook - in the form of needles - is often used to catch burbot. This hook is a wooden stick or bone, pointed at both ends, twine tied in the middle. As a bait is placed a little fish. When the fish swallows the bait along the spoke, the latter becomes the throat of fish. Of the spokes are arranged kiddle. Hooks for catching Kunzhi Read more [...]
