Guitar picking is a group of hand and finger techniques a guitarist uses to set guitar strings in motion to produce audible notes. These techniques involve plucking, strumming, brushing, etc. Picking can be done with: A pick (plectrum) held in the hand Natural or artificial fingernails, fingertips or finger-mounted plectrums known as fingerpicks (for techniques collectively known as fingerstyle) A plectrum held between thumb and one finger, supplemented by the free fingers—called hybrid picking or sometimes "chicken pickin".Using a single thumb pick with the bare fingers is similar to hybrid picking. Another mixed technique is to play different passages with a plectrum or fingerstyle, "palming" the plectrum when not in use. This however requires the use of one or more picking hand fingers, and/or can reduce dexterity in the picking hand. Comparison of plectrum and finger picking techniques The pros of each guitar picking style are indirectly correlated to the...

Vagrancy is the condition of homelessness without regular employment or income. Vagrants (also known as bums, vagabonds, rogues, drag-worms, drag-rats, tramps or drifters) usually live in poverty and support themselves by begging, scavenging, petty theft, temporary work, or social security (where available). Historically, vagrancy in Western societies was associated with petty crime, begging and lawlessness, and punishable by law with forced labor, military service, imprisonment, or confinement to dedicated labor houses. Both vagrant and vagabond ultimately derive from the Latin word vagari, meaning "to wander". The term vagabond is derived from Latin vagabundus. In Middle English, vagabond originally denoted a person without a home or employment. Historical views Vagrants have been historically characterised as outsiders in settled, ordered communities: embodiments of otherness, objects of scorn or mistrust, or worthy recipients of help and charity. Some ancient sources show vagrants as...

Surgical mesh is a loosely woven sheet which is used as either a permanent or temporary support for organs and other tissues during surgery. Surgical mesh is created from both inorganic and biological materials and is used in a variety of surgeries. Though hernia repair surgery is the most common application, it can also be used for reconstructive work, such as in pelvic organ prolapse.Permanent meshes remain in the body, whereas temporary ones dissolve over time. One temporary mesh was shown in 2012 to fully dissolve after three years in a scientific trial on sheep. Some types of mesh combine permanent and temporary meshes which includes both resorbable vicryl, made from polyglycolic acid, and prolene, a non-resorbable polypropylene.Data of mechanical and biological behaviors of mesh in vivo may not always be reflective of conditions within the human body due to testing in non-human organisms. Most published reports experiment on mice, thus creating the likelihood of possible differences when inserted into the human body. Also, most published research reports reference meshes that are currently disallowed from the medical device market due to complications...
