Structure of heart

The structure of the heart varies among the different branches of the animal kingdom. Cephalopods have two "gill hearts" and one "systemic heart". Fish have a two-chambered heart that pumps the blood to the gills and from there it goes on to the rest of the body. In amphibians and most reptiles, a double circulatory system is used, but the heart is not always completely separated into two pumps. Amphibians have a three-chambered heart

Surface anatomy of the heart. The heart is demarcated by:-A point 9 cm to the left of the midsternal line (apex of the heart)-The seventh right sternocostal articulation-The upper border of the third right costal cartilage 1 cm from the right sternal line-The lower border of the second left costal cartilage 2.5 cm from the left lateral sternal line.
Birds and mammals show complete separation of the heart into two pumps, for a total of four heart chambers; it is thought that the four-chambered heart of birds evolved independently from that of mammals.
In the human body, the heart is usually situated in the middle of the thorax with the largest part of the heart slightly offset to the left (although sometimes it is on the right, see dextrocardia), underneath the sternum. The heart is usually felt to be on the left side because the left heart (left ventricle) is stronger (it pumps to all body parts). The left lung is smaller than the right lung because the heart occupies more of the left hemithorax. The heart is fed by the coronary circulation and enclosed by a sac known as the pericardium and is surrounded by the lungs. The pericardium comprises two parts: the fibrous pericardium, made of dense fibrous connective tissue; and a double membrane structure (parietal and visceral pericardium) containing a serous fluid to reduce friction during heart contractions. The heart is located in the mediastinum, the central sub-division of the thoracic cavity. The mediastinum also contains other structures, such as the esophagus and trachea, and is flanked on either side by the right and left pulmonary cavities, which house the lungs.
The apex is the blunt point situated in an inferior (pointing down and left) direction. A stethoscope can be placed directly over the apex so that the beats can be counted. It is located posterior to the 5th intercostal space just medial of the left mid-clavicular line. In normal adults, the mass of the heart is 250-350 gor about twice the size of a clenched fist (it is about the size of a clenched fist in children), but extremely diseased hearts can be up to 1000 g in mass due to hypertrophy. It consists of four chambers, the two upper atria and the two lower ventricles.

Culture of Nepal

Nepalese culture is diverse, reflecting different ethnic origins of the people. The Newar community is particularly rich in cultural diversity; they celebrate many festivals, well known for their music and dance.
A typical Nepalese meal is dal-bhat-tarkari. Dal is a spicy lentil soup, served over bhat (boiled rice), served with tarkari (curried vegetables) together with achar (pickles) or chutni (spicy condiment made from fresh ingredients).. The Newar community, however, has its own unique cuisine. It consists of non-vegetarian as well as vegetarian items served with alcoholic and non-alcoholic beverages. Mustard oil is the cooking medium and a host of spices, such as cumin, coriander, black peppers, sesame seeds, turmeric, garlic, ginger, methi (fenugreek), bay leaves, cloves, cinnamon, pepper, chillies, mustard seeds, etc., are used in the cooking. The cuisine served on festivals is generally the best.

The Newari Music orchestra consists mainly of percussion instruments, though wind instruments, such as flutes and other similar instruments, are also used. String instruments are very rare. There are songs pertaining to particular seasons and festivals. Paahan chare music is probably the fastest played music whereas the Dapa the slowest. There are certain musical instruments such as Dhimay and Bhusya which are played as instrumental only and are not accompanied with songs. The dhimay music is the loudest one. In the hills, people enjoy their own kind of music, playing saarangi (a string instrument), madal and flute. They also have many popular folk songs known as lok geet and lok dohari.
The Newar dances can be broadly classified into masked dances and non-masked dances. The most representative of Newari dances is Lakhey dance. Almost all the settlements of Newaris organise Lakhey dance at least once a year, mostly in the Goonlaa month. So, they are called Goonlaa Lakhey. However, the most famous Lakhey dance is the Majipa Lakhey dance; it is performed by the Ranjitkars of Kathmandu and the celeberation continues for the entire week that contains the full moon of Yenlaa month. The Lakhey are considered to be the saviors of children.
Folklore is an integral part of Nepalese society. Traditional stories are rooted in the reality of day-to-day life, tales of love, affection and battles as well as demons and ghosts and thus reflect local lifestyles, cultures and beliefs. Many Nepalese folktales are enacted through the medium of dance and music.
The Nepali year begins in mid-April and is divided into 12 months. Saturday is the official weekly holiday. Main annual holidays include the National Day, celebrated on the birthday of the king (December 28), Prithvi Jayanti (January 11), Martyr's Day (February 18), and a mix of Hindu and Buddhist festivals such as dashain in autumn, and tihar in late autumn. During tihar, the Newar community also celebrates its New Year as per their local calendar Nepal Sambat.
Most houses in rural lowland of Nepal are made up of a tight bamboo framework and walls of a mud and cow-dung mix. These dwellings remain cool in summer and retain warmth in winter. Houses in the hills are usually made of unbaked bricks with thatch or tile roofing. At high elevations construction changes to stone masonry and slate may be used on roofs.
Nepal's flag is the only national flag in the world that is non-quadrilateral in shape, and one of only two non-rectangular flags in use (the other being the flag of the U.S. state of Ohio). According to its official description, the red in the flag stands for victory in war or courage, and is also color of the rhododendron, the national flower of Nepal. Red also stands for aggression. The flag's blue border signifies peace. The curved moon on the flag is a symbol of the peaceful and calm nature of Nepalese, while the sun represents the aggressiveness of Nepalese warriors.

Nepal

Nepal (Nepali: नेपाल officially the Federal Democratic Republic of Nepal, is a landlocked country in South Asia and is the world's youngest republic. It is bordered to the north by the People's Republic of China, and to the south, east, and west by the Republic of India. With an area of 147,181 square kilometers and a population of approximately 30 million, Nepal is the world's 93rd largest country by land mass[3] and the 41st most populous country. Kathmandu is the nation's capital and the country's largest metropolitan city.
Nepal is a country of highly diverse and rich geography, culture, and religions. The mountainous north contains eight of the world's ten highest mountains, including the highest, Mount Everest. The fertile and humid south is heavily urbanized. By some measures, Hinduism is practiced by a greater majority of people in Nepal than in any other nation. [4]. A minority faith in the country, Buddhism is linked historically with Nepal as the birthplace of Siddhartha Gautama who, as the Buddha Gautama, gave birth to the Buddhist tradition.
Nepal had been a monarchy throughout most of its history. Prithvi Narayan Shah, a Shah dynasty king, unified the many small kingdoms in 1768. Since then, the country had been ruled by a dynasty of kings. However, a decade-long People's Revolution by the Communist Party of Nepal (Maoist) along with several weeks of mass protests by all major political parties of Nepal in 2006, culminated in a peace accord and the ensuing elections for the constituent assembly voted overwhelmingly in favor of the abdication of the last Nepali monarch Gyanendra Shah and the establishment of a federal democratic republic in May 28, 2008.The first President of Nepal, Dr. Ram Baran Yadav was sworn in on 23 July, 2008

Supermarket

The supermarket typically comprises meat, fresh produce, dairy, and baked goods departments along with shelf space reserved for canned and packaged goods as well as for various nonfood items such as household cleaners, pharmacy products, and pet supplies. Most supermarkets also sell a variety of other household products that are consumed regularly, such as alcohol (where permitted), household cleaning products, medicine, clothes, and some sell a much wider range of nonfood products.
The traditional suburban supermarket occupies a large amount of floor space, usually on a single level, and is situated near a residential area in order to be convenient to consumers. Its basic appeal is the availability of a broad selection of goods under a single roof at relatively low prices. Other advantages include ease of parking and, frequently, the convenience of shopping hours that extend far into the evening or even 24 hours a day. Supermarkets usually make massive outlays of newspaper and other advertising and often present elaborate in-store displays of products. The stores often are part of a corporate chain that owns or controls (sometimes by franchise) other supermarkets located nearby — even transnationally — thus increasing opportunities for economies of scale.
In North America, supermarkets typically are supplied by the distribution centers of its parent company, such as Loblaw Companies in Canada, which operates thousands of supermarkets across the nation. Loblaw operates a distribution center in every province — usually in the largest city in the province.
Supermarkets usually offer products at low prices by reducing their economic margins. Certain products (typically staple foods such as bread, milk and sugar) are occasionally sold as loss leaders, that is, with negative profit margins. To maintain a profit, supermarkets attempt to make up for the lower margins by a higher overall volume of sales, and with the sale of higher-margin items. Customers usually shop by placing their selected merchandise into shopping carts (trolleys) or baskets (self-service) and pay for the merchandise at the check-out. At present, many supermarket chains are attempting to further reduce labor costs by shifting to self-service check-out machines, where a single employee can oversee a group of four or five machines at once, assisting multiple customers at a time.
A larger full-service supermarket combined with a department store is sometimes known as a hypermarket. Other services offered at some supermarkets may include those of banks, cafés, childcare centers/creches, photo processing, video rentals, pharmacies, and/or gas stations.
Supermarkets use stock rotation, the practice of moving products with an earlier sell-by date to the front of a shelf so they get picked up and sold first.

Forest

A forest is an area with a high density of trees. There are many definitions of a forest, based on the various criteria.These plant communities presently cover approximately 9.4% of the Earth's surface (or 30% of total land area) in many different regions and function as habitats for organisms, hydrologic flow modulators, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. Although a forest is classified primarily by trees a forest ecosystem is defined intrinsically with additional species such as fungi.A woodland, with more open space between trees, is ecologically distinct from a forest

Existence of God

Many arguments which attempt to prove or disprove the existence of God have been proposed by philosophers, theologians, and other thinkers for many centuries. In philosophical terminology, such arguments concern schools of thought on the epistemology of the ontology of God.
There are many philosophical issues concerning the existence of God. Some definitions of God are sometimes nonspecific, while other definitions can be self-contradictory. Arguments for the existence of God typically include metaphysical, empirical, inductive, and subjective types, while others revolve around holes in evolutionary theory and order and complexity in the world. Arguments against the existence of God typically include empirical, deductive, and inductive types. Conclusions reached include: "God does not exist" (strong atheism); "God almost certainly does not exist"(de facto atheism); "no one knows whether God exists" (agnosticism); "God exists, but this cannot be proven or disproven" (theism); and "God exists and this can be proven" (theism). There are numerous variations on these positions.
A recent argument for the existence of God is intelligent design,[17] which asserts that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection."[18] It is a modern form of the traditional argument from design, modified to avoid specifying the nature or identity of the designer. Its primary proponents, all of whom are associated with the Discovery Institute,[19] believe the designer to be the Abrahamic God.

Mount Everest

Mount Everest – also called Sagarmatha (Nepali: सगरमाथा), Chomolungma or Qomolangma or Zhumulangma – is the highest mountain on Earth, as measured by the height above sea level of its summit, 8,848 metres (29,029 ft). The mountain, which is part of the Himalaya range in Asia, is located on the border between Sagarmatha Zone, Nepal, and Tibet, China.
In 1856, the Great Trigonometric Survey of India established the first published height of Everest, then known as Peak XV, at 29,002 ft (8,840 m). In 1865, Everest was given its official English name by the Royal Geographical Society upon recommendation of Andrew Waugh, the British Surveyor General of India at the time. Chomolungma had been in common use by Tibetans for centuries, but Waugh was unable to propose an established local name because Nepal and Tibet were closed to foreigners.
The highest mountain in the world attracts climbers of all levels, from well experienced mountaineers to novice climbers willing to pay substantial sums to professional mountain guides to complete a successful climb. The mountain, while not posing substantial technical climbing difficulty on the standard route (other eight-thousanders such as K2 or Nanga Parbat are much more difficult), still has many inherent dangers such as altitude sickness, weather and wind. By the end of the 2008 climbing season, there had been 4,102 ascents to the summit by about 2,700 individuals. Climbers are a significant source of tourist revenue for Nepal, whose government also requires all prospective climbers to obtain an expensive permit, costing up to US$25,000 per person. Everest has claimed 210 lives, including eight who perished during a 1996 storm high on the mountain. Conditions are so difficult in the death zone that most corpses have been left where they fell. Some of them are visible from standard climbing routes.
