Vitis

Vitis (grapevines) is a genus of about 60 species of vining plants in the flowering plant family Vitaceae. The genus is made up of species predominantly from the Northern hemisphere. It is economically important as the source of grapes, both for direct consumption of the fruit and for fermentation to produce wine. The study and cultivation of grapevines is called viticulture.

All vines share the same basic, physiological features. The roots anchor the vine to the soil and serve as the conduit where nutrients and water from the soil are absorbed. Along with the trunk or "permanent wood" features, the roots also serve as storage reserve of carbohydrates which the vine can use for energy in the winter after the leaves have fallen and are no longer conducting photosynthesis. The function of photosynthesis in the grapevine is to produce glucose which can be combined with other molecules to form larger carbohydrates (such as cellulose) that can be used to create other structures in the vine, energy reserves for the plant and, for fruiting grapevines, can be concentrated in grape berries which contain the reproductive seeds of the vine and are more attractive to birds and other animals.

Grapevine (disk magazine)

Grapevine was a disk magazine for the Commodore Amiga published by the demo scene group LSD. The first eight issues each came on a single floppy disk, but as the magazine became more popular and more articles were submitted by its readers, it required two to three disks per issue after that point. The editor of Grapevine was known as Parasite, later PaZZa/LSD. The magazine was originally coded by Monty Python, and then re-coded with a mouse driven interface later in the series by Shagratt.

Grapevine existed at a time when Internet use was not widespread in its native UK or abroad, and hence editions of the magazine were hotly traded amongst the demo scene. LSD sent out hundreds of floppy disk copies on each release, and most PD libraries at the time were keen to include the latest issues as soon as they were released. As a result of this, 17Bit PD library cut a deal with PaZZa to ensure distribution at a fair price, they were "paid" a box of 50 floppy disks per issue for this, which were used by LSD for file distribution (the days before modems for many people).

Canopy (grape)

In viticulture, the canopy of a grapevine includes the parts of the vine visible aboveground - the trunk, cordon, stems, leaves, flowers, and fruit. The canopy plays a key role in light energy capture via photosynthesis, water use as regulated by transpiration, and microclimate of ripening grapes.Canopy management is an important aspect of viticulture due to its effect on grape yields, quality, vigor, and the prevention of grape diseases. Various viticulture problems, such as uneven grape ripening, sunburn, and frost damage, can be addressed by skillful canopy management. In addition to pruning and leaf trim, the canopy is often trained on trellis systems to guide its growth and assist in access for ongoing management and harvest.

Vine

The vine is the main part of the grapevine, extending from the root system in the ground up to the cordons, or arms, of the vine. When the grape is young the trunk is very pliable and must be supported by stakes as part of a vine training system. The height of the trunk varies depending on grape variety and the type of trellis system being used and can range from 4 inches (10 cm) to 30 feet (10 m). During winter dormancy, the trunk can be vulnerable to extreme freezing conditions and will be sometimes buried and insulated with soil to protect it.

Core (functional analysis)

In functional analysis, a discipline within mathematics, a core may be:

Core (anatomy)

In common parlance, the core of the body is broadly considered to be the torso. Functional movements are highly dependent on this part of the body, and lack of core muscular development can result in a predisposition to injury. The major muscles of the core reside in the area of the belly and the mid and lower back (not the shoulders), and peripherally include the hips, the shoulders and the neck.

Muscles

Major muscles included are the pelvic floor muscles, transversus abdominis, multifidus, internal and external obliques, rectus abdominis, erector spinae (sacrospinalis) especially the longissimus thoracis, and the diaphragm. Minor core muscles include the latissimus dorsi, gluteus maximus, and trapezius.

Functions of the core

The core is used to stabilize the thorax and the pelvis during dynamic movement and it also provides internal pressure to expel substances (vomit, feces, carbon-laden air, etc.).

Continence is the ability to withhold bowel movements, and urinary stress incontinence (the lack of bladder control due to pelvic floor dysfunction) can result from weak core musculature.
