A tattoo is a form of body modification where a design is made by inserting ink, dyes, and pigments, either indelible or temporary, into the dermis layer of the skin to change the pigment. The art of making tattoos is tattooing. Tattoos fall into three broad categories: purely decorative (with no specific meaning); symbolic (with a specific meaning pertinent to the wearer); and pictorial (a depiction of a specific person or item). In addition, tattoos can be used for identification such as ear tattoos on livestock as a form of branding. The word tattoo, or tattow in the 18th century, is a loanword from the Samoan word tatau, meaning "to strike". The Oxford English Dictionary gives the etymology of tattoo as "In 18th c. tattaow, tattow. From Polynesian (Samoan, Tahitian, Tongan, etc.) tatau. In Marquesan, tatu." Before the importation of the Polynesian word, the practice of tattooing had been described in the West as painting, scarring or staining. The etymology of

Unmanned aerial vehicle Abraham Karem Abraham Karem is a pioneer in innovative fixed and rotary-wing unmanned vehicles and is regarded as the founding father of UAV (drone) technology. Unmanned aerial vehicle An unmanned aerial vehicle (UAV) (or uncrewed aerial vehicle, commonly known as a drone) is an aircraft without a human pilot on board. UAVs are a component of an unmanned aircraft system (UAS); which includes a UAV, a ground-based controller, and a system of communications between the two. The flight of UAVs may operate with various degrees of autonomy: either under remote control by a human operator or autonomously by onboard computers referred to as an autopilot. Compared to crewed aircraft, UAVs were originally used for missions too "dull, dirty, or dangerous" for humans. While drones originated mostly in military applications, their use is rapidly finding many more applications including aerial photography, product deliveries, agriculture, policing and surveillanc

YOGA The ultimate goal of Yoga is Moksha although the exact form this takes depends on the philosophical or theological system with which it is conjugated. In the classical Astanga yoga system, the ultimate goal of yoga practice is to achieve the state of Samadhi and abide in that state as pure awareness. According to Jacobsen, Yoga has five principal traditional meanings A disciplined method for attaining a goal. Techniques for controlling the body and the mind. A name of a school or system of philosophy (darśana). With prefixes such as "Hatha-, mantra-, and laya-, traditions specializing in particular techniques of yoga. The goal of Yoga practice. According to David Gordon White, from the 5th century CE onward, the core principles of "yoga" were more or less in place and variations of these principles developed in various forms over time A meditative means of discovering dysfunctional perception and cognition, as well as overcoming it to release any suffering, find inn

YOGA  This article is about a group of physical, mental, and spiritual practices originating in ancient India.  There is a broad variety of yoga schools, practices, and goals in Hinduism, Buddhism, and Jainism. The term "Yoga" in the Western world often denotes a modern form of hatha yoga and yoga as exercise, consisting largely of the postures or asanas. The practice of yoga has been thought to date back to pre-Vedic Indian traditions; possibly in the Indus valley civilization around 3000 BCE. Yoga is mentioned in the Rigveda, and also referenced in the Upanishads,. Although, yoga most likely developed as a systematic study around the 5th and 6th centuries BCE, in ancient India's ascetic and Śramaṇa movements.  The chronology of earliest texts describing yoga-practices is unclear, varyingly credited to the Upanishads. The Yoga Sutras of Patanjali date from the 2nd century BCE, and gained prominence in the west in the 20th century after being first introduced by Swami Viv

PREGNANCY EXERCISE Regular aerobic exercise during pregnancy appears to improve (or maintain) physical fitness. Physical exercise during pregnancy does appear to decrease the need for C-section. Bed rest, outside of research studies, is not recommended as there is no evidence of benefit and potential harm. The Clinical Practice Obstetrics Committee of Canada recommends that "All women without contraindications should be encouraged to participate in aerobic and strength-conditioning exercises as part of a healthy lifestyle during their pregnancy". Although an upper level of safe exercise intensity has not been established, women who were regular exercisers before pregnancy and who have uncomplicated pregnancies should be able to engage in high-intensity exercise programs. In general, participation in a wide range of recreational activities appears to be safe, with the avoidance of those with a high risk of falling such as horseback riding or skiing or those that carry a risk

Bouldering Bouldering is a form of rock climbing that is performed on small rock formations or artificial rock walls without the use of ropes or harnesses.  While bouldering can be done without any equipment, most climbers use climbing shoes to help secure footholds, chalk to keep their hands dry and to provide a firmer grip, and bouldering mats to prevent injuries from falls.     Unlike free solo climbing, which is also performed without ropes, bouldering problems (the sequence of moves that a climber performs to complete the climb) are usually less than 6 meters (20 ft.) tall.  Traverses, which are a form of a boulder problem, require the climber to climb horizontally from one end to another.[1] Artificial climbing walls allow boulderers to climb indoors in areas without natural boulders. In addition, bouldering competitions take place in both indoor and outdoor settings. The sport was originally a method of training for roped climbs and mountaineering, so climbers could practice spe

Prosthesis In  medicine , a  prosthesis  from  Ancient Greek   prosthesis , or  prosthetic  implant   is an artificial device that replaces a missing body part, which may be lost through trauma, disease, or a condition present at birth ( congenital disorder ).  Prostheses are intended to restore the normal functions of the missing body part.   Amputee  rehabilitation is primarily coordinated by a  physiatrist  as part of an interdisciplinary team consisting of physiatrists, prosthetists, nurses, physical therapists, and occupational therapists.   Prostheses can be created by hand or with  computer-aided design  (CAD), a software interface that helps creators design and analyze the creation with computer-generated  2-D  and  3-D graphics  as well as analysis and optimization tools. Iron prosthetic hand believed to have been owned by Götz von Berlichingen (1480–1562) Over the years, there have been advancements in artificial limbs. New plastics and other materials, such as  carbon fiber

                   Great Wall of China The  Great Wall of China   城 ;  simplified Chinese : is a series of  fortifications  that were built across the historical northern borders of  ancient Chinese states  and  Imperial China  as protection against  various nomadic groups  from the  Eurasian Steppe .  Several walls were built from as early as the 7th century BC with selective stretches later joined together by  Qin Shi Huang  (220–206 BC), the first emperor of China. Little of the Qin wall remains. Later on, many successive dynasties have built and maintained multiple stretches of border walls. The most well-known sections of the wall were built by the  Ming dynasty  (1368–1644). Apart from defense, other purposes of the Great Wall have included  border controls , allowing the imposition of duties on goods transported along the  Silk Road , regulation or encouragement of trade, and the control of immigration and emigration.  Furthermore, the defensive characteristics of the Great Wall

                                  CONSTRUCTION SITE Construction  is a general term meaning the art and science to form objects, systems, or organizations, and comes from Latin  constructio  and Old French  construction . To construct is the verb: the act of building and the noun is construction: how something is built, the nature of its structure.             In its most widely used context, construction covers the processes involved in delivering  buildings ,  infrastructure  and industrial facilities, and associated activities through to the end of their life.               It typically starts with  planning ,  financing , and  design , and continues until the asset is built and ready for use; construction also covers repairs and maintenance work, and works to expand, extend and improve the asset, and its eventual  demolition , dismantling, or  decommissioning .                As an  industry  sector, construction accounts for more than 10% of global  GDP  (6-9% in  developed countr

Bridge A  bridge  is a  structure  built to  span  a physical obstacle, such as a  body of water ,  valley , or  road , without closing the way underneath. It is constructed for the purpose of providing passage over the obstacle, usually something that is otherwise difficult or impossible to cross. There are many different designs that each serve a particular purpose and apply to different situations. Designs of bridges vary depending on the function of the bridge, the nature of the  terrain  where the bridge is constructed and anchored, the material used to make it, and the funds available to build it. Most likely the earliest bridges were fallen trees and  stepping stones , while  Neolithic  people built  boardwalk  bridges across marshland. The  Arkadiko Bridge  dating from the 13th century BC, in the  Peloponnese , in southern Greece is one of the oldest  arch bridges  still in existence and use. The simplest type of bridge is  stepping stones , so this may have been one of the ear

Interior design Interior design  is the  art  and  science  of enhancing the interior of a  building  to achieve a healthier and more aesthetically pleasing environment for the people using the space.  An  interior designer  is someone who plans, researches, coordinates, and manages such enhancement projects. Interior design is a multifaceted profession that includes conceptual development, space planning, site inspections, programming, research, communicating with the stakeholders of a project, construction management, and execution of the design. In the past, interiors were put together instinctively as a part of the process of building. The profession of interior design has been a consequence of the development of society and the complex architecture that has resulted from the development of industrial processes. The pursuit of effective use of space, user well-being and functional design has contributed to the development of the contemporary interior design profession. The professi
