History of animation
Early examples of attempts to capture the phenomenon of motion drawing can be found in paleolithic cave paintings, where animals are depicted with multiple legs in superimposed positions, clearly attempting to convey the perception of motion.
A 5,000 year old earthen bowl found in Iran in Shahr-i has five images of a goat painted along the sides. This has been claimed to be an example of early animation. However, since no equipment existed to show the images in motion, such a series of images cannot be called animation in a true sense of the word.

Mordern Music
Modern history :
The modern history is a very short one. At times when big and private music companies where mushrooming the Western cities, Kathmandu got its first radio station, Radio Nepal in the year 1952. Since then Radio Nepal has expanded to become the dominant radio station all over the country, which helped in the uprising of many key figures in the field, notably Shiva Shankar, Natikaji, Narayan Gopal, Arun Thapa Magar (also known as Arun Thapa, Dharma Raj Thapa, Jhalak Man Gandarva, and in the female arena Koili Devi Mathema, Tara Devi (singer)Tara Devi, Aruna Lama.
Those music genres which have roots in Nepal can be considered as indigenous Nepalese music.

Culture of Nepal
Dance and music
Main article: Music of Nepal
Legends state that dances in the Indian subcontinent originated in the abode of Lord Shiva - the Himalayas and the Himalayan Kingdom of Nepal - where he performed the tandava dance. This indicates that dance traditions of Nepal are of very ancient origin. With altitudes and ethnicity, the dances of Nepal slightly change in style as well as in the dance costumes. Accompanying music and musical instruments also change in tune with the themes, which revolve around topics like harvesting of crops, marriage rites, war stories, a lonely girl’s yearning for her love, and several other themes and stories from everyday life in the villages.
Languages and literatures
Main article: Languages of Nepal
As per 2001 census, at least 92 different living languages are spoken in Nepal, though other studies list 123 living languages. Nepal’s linguistic heritage has evolved from three major language groups, namely, Indo-Aryan, Tibeto-Burman, and indigenous. The major languages of Nepal (percent spoken as mother tongue) are Nepali (49%), Maithili (12%), Bhojpuri (8%), Tharu (6%), Tamang (5%), Newari/Nepal Bhasa (4%), Magar (3%), Awadhi (2%), Thulung (Rai) (3%),Bantawa (2%), Limbu (1%), and Bajjika (1%). The remaining languages are each spoken as mother tongue by less than one percent of the population, for example Dura. Nepali, written in Devanagari script, is the official, national language and serves as lingua franca among Nepalese of different ethno-linguistic groups. In the southern Terai Region, (5 to 10 mile wide stretch of flat plains, which is a northward continuation of Gangetic plains of India), Hindi is also spoken. Extinct languages of Nepal include Kusunda and Waling. Among notable writers of Nepalese literature is Parijat and Jhamak Ghimire.
Religions and philosophy
Main article: Religion in Nepal
The 2001 census identified 80.6% of the population as Hindu and Buddhism was practiced by about 11% of the population (although many people labelled Hindu or Buddhist often practice a syncretic blend of Hinduism, Buddhism and/or animist traditions). About 3.2%of the population is Muslim and 3.6% of the population follows the indigenous Kirant religion. Christianity is practiced officially by less than 0.5% of the population.
Hindu and Buddhist traditions in Nepal go back to more than two millennia. In Lumbini, Buddha was born, and Pashupatinath temple, Kathamandu, is an old and famous Shiva temple of Hindus. Nepal has several other temples and Buddhist monasteries as well as places of worship of other religious groups. Traditionally, Nepalese philosophical thoughts are ingrained with the Hindu and Buddhist philosophical ethos and traditions, which include elements of Kashmir Shaivism, Nyingma school of Tibetan Buddhism, works of Karmacharyas of Bhaktapur, and a variety of tantric traditions. Tantric traditions are deep rooted in Nepal, including the practice of animal sacrifices. Five types of animals, always male, are considered acceptable for sacrifice: water buffalo, goats, sheep, chickens, and ducks.
With a multiplicity of groups, Nepal has several cults, and gods and goddesses, which co-exist with the major religions. In its long cultural history, Nepal has always remained a land of religious harmony.

nepali film industry
Nepal is a small country which is re-known by its naatural resources and scenic beauty. It does not have a very long film history but the industry has its own place in the cultural heritage of the country. Most Nepali films use Bollywood-style songs and narrative and are shot on 16-millimeter film. In film industry parlance, Kathmandu, the capital and center of the Nepali-language film industry, is called Kollywood
History
The making of Nepali films is said to have begun with D.B. Pariyar's ''[[Satya Harishchandra (1951 film)|Satya Harishchandra]]'', which was the first Nepali language film to be shot. It was produced from [[Kolkata, India]], and was released on September 14, 1951. ''Aama'' (meaning mother) was the first film produced in Nepal, and was released on October 7, 1964. It was produced by the Information Department of His Majesty's Government of Nepal (now Government of Nepal). It was directed by Hira Singh Khatri and the lead actors were Shiva Shankar and Bhuwan Thapa, who are regarded as the first actors in the history of the Nepali film industry.
The first film to be produced under a private banner was ''Maitighar'' (meaning the birth home of a girl), which was released at the end of 1966 by Sumonanjali Films Pvt. Ltd. Although it was a Nepali movie, it had many Indians contributing toward the making of the film. [[Mala Sinha]] played the lead role, along with Chidambar Prasad Lohani, whom she later married. It had special appearances of [[Sunil Dutt]] and comedian [[Rajendra Nath]]. Directed by B.S. Thapa and music scored by [[Jaidev]], a veteran music maestro, it had [[Lata Mangeshkar]], [[Asha Bhosle]], [[Usha Mangeshkar]] and [[Manna Dey]], all of whom were established Indian singers, doing the playback singing by Prem Dhoj Pradhan, C.P. Lohani and [[Aruna Lama]].
The Nepal government established the Royal Nepal Film Corporation in 1971. ''Mann Ko Bandh'' was the first film produced by the corporation. Prakesh Thapa was the director of the film. Nati Kaji and Shiva Shankar were the music composers of the songs. [[Amber Gurung]] scored the background music. The film premiered in 1973 in [[Kathmandu]]. ''Mann Ko Bandh'' was followed by ''Kumari'' (the first [[Eastman color]] Nepali film) in 1977, ''Sindoor'' in 1980, and ''Jeevan Rekha'' in a series. The success of these films opened up the avenue for private parties to enter into filmmaking as an industrial endeavor.
The movie ''Paral Ko Aago'', directed by Pratap Subba, was produced by Ceneroma in 1978. The black-and-white movie proved to be a great success due to its story and melodious music. The music director of the movie, Shanti Thatal, was the first female music director in Nepali movies. Lyrics were prepared by Manbahadur Mukhiya and Indra Thapaliya and the songs were sung by [[Aruna Lama]], Dawa Gyalmo, Pema Lama, Shankar Gurung and Deepa Gahatraj (Jha). The actors of the movie were Tanka Sharma, Basundhara Bhusal, I.K. Singh, Menuka Pradhan, etc. Pratap Subba was also the scriptwriter. The movie was based on a popular book by [[Guru Prasad Mainali]] with the same title.

History and development of schools
History and development of schools
Main article: History of education
The concept of grouping students together in a centralized location for learning has existed since Classical antiquity. Formal schools have existed at least since ancient Greece (see Academy), ancient Rome (see Education in Ancient Rome) ancient India (see Gurukul), and ancient China (see History of education in China). The Byzantine Empire had an established schooling system beginning at the primary level. According to Traditions and Encounters, the founding of the primary education system began in 425 A.D. and "... military personnel usually had at least a primary education ...". The sometimes efficient and often large government of the Empire meant that educated citizens were a must. Although Byzantium lost much of the grandeur of Roman culture and extravagance in the process of surviving, the Empire emphasized efficiency in its war manuals. The Byzantine education system continued until the empire's collapse in 1453 AD.[1]
Islam was another culture that developed a school system in the modern sense of the word. Emphasis was put on knowledge, which required a systematic way of teaching and spreading knowledge, and purpose-built structures. At first, mosques combined both religious performance and learning activities, but by the ninth century, the Madrassa was introduced, a proper school that was built independently from the mosque. They were also the first to make theMadrassa system a public domain under the control of the Caliph. The Nizamiyya madrasa is considered by consensus of scholars to be the earliest surviving school, built towards 1066 CE by Emir Nizam Al-Mulk.[citation needed]
Under the Ottomans, the towns of Bursa and Edirne became the main centers of learning. The Ottoman system of Külliye, a building complex containing a mosque, a hospital, madrassa, and public kitchen and dining areas, revolutionized the education system, making learning accessible to a wider public through its free meals, health care and sometimes free accommodation.
The nineteenth century historian, Scott holds that a remarkable correspondence exists between the procedure established by those institutions and the methods of the present day. They had their collegiate courses, their prizes for proficiency in scholarship, their oratorical and poetical contests, their commencements and their degrees. In the department of medicine, a severe and prolonged examination, conducted by the most eminent physicians of the capital, was exacted of all candidates desirous of practicing their profession, and such as were unable to stand the test were formally pronounced incompetent.[citation needed]
In Europe during the Middle Ages and much of the Early Modern period, the main purpose of schools (as opposed to universities) was to teach the Latin language. This led to the term grammar school, which in the United States informally refers to a primary school, but in the United Kingdom means a school that selects entrants based on ability or aptitude. Following this, the school curriculum has gradually broadened to include literacy in the vernacular language as well as technical, artistic, scientific and practical subjects.
Many of the earlier public schools in the United States were one-room schools where a single teacher taught seven grades of boys and girls in the same classroom. Beginning in the 1920s, one-room schools were consolidated into multiple classroom facilities with transportation increasingly provided by kid hacks and school buses.

P2P Software
The word P2P means peer-to-peer computing software or workloads among peers. They are very easy, equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes. It make's a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. Peers are both suppliers and consumers of resources, in contrast to the traditional client–server model where only servers supply , and clients consume . All these kind of software plays a vital role in work performance. The peer-to-peer application structure was popularized by file sharing systems like Napster. The concept has inspired new
structures and philosophies in many areas of human interaction. Peer-to-peer networking is not restricted to technology,
but covers also social processes with a peer-to-peer dynamic. In such context, social peer-to-peer processes are currently
emerging throughout society. P2P has two way to define.
Structured P2P and un Structured P2P .
Structured P2P networks employ a globally consistent protocol to ensure that any node can efficiently route a search to some
peer that has the desired file, even if the file is extremely rare. Such a guarantee necessitates a more structured pattern of overlay links. frostwire 4.20.9 can downloaded for P2P computing.
By far the most common type of structured P2P network is the distributed hash table (DHT), in which a variant of consistent hashing is
used to assign ownership of each file to a particular peer, in a way analogous to a traditional hash table's assignment of each key to a
particular array slot. The another one is an unstructured P2P network.
An unstructured P2P network is is formed when the overlay links are established arbitrarily. Such networks can be easily constructed as a
new peer that wants to join the network can copy existing links of another node and then form its own links over time. In an unstructured
P2P network, if a peer wants to find a desired piece of data in the network, the query has to be flooded through the network to find as
many peers as possible that share the data. The main disadvantage with such networks is that the queries may not always be resolved.
Popular content is likely to be available at several peers and any peer searching for it is likely to find the same thing. But if a peer is
looking for rare data shared by only a few other peers, then it is highly unlikely that search will be successful. Since there is no correlation
between a peer and the content managed by it, there is no guarantee that flooding will find a peer that has the desired data.
Flooding also causes a high amount of signaling traffic in the network and hence such networks typically have very poor search efficiency.
Many of the popular P2P networks are unstructured.
In pure P2P networks: Peers act as equals, merging the roles of clients and server. In such networks, there is no central server managing the network, neither is there a central router. Some examples of pure P2P Application Layer networks designed for peer-to-peer file sharing are gnutella (pre v0.4) and Freenet.
There also exist hybrid P2P systems, which distribute their clients into two groups: client nodes and overlay nodes. Typically, each client is able to act according to the momentary need of the network and can become part of the respective overlay network used to coordinate the P2P structure. This division between normal and 'better' nodes is done in order to address the scaling problems on early pure P2P networks. As examples for such networks can be named modern implementations of gnutella (after v0.4) and Gnutella2.
Another type of hybrid P2P network are networks using on the one hand central server or bootstrapping mechanisms, on the other hand P2P
for their data transfers. These networks are in general called 'centralized networks' because of their lack of ability to work without their
central server(s). An example for such a network is the eDonkey network (often also called eD2k).

smoking habit
Smoking is a practice in which a substance, most commonly tobacco or cannabis, is burned and the smoke is tasted or inhaled. This is primarily practised as a route of administration for recreational drug use, as combustion releases the active substances in drugs such as nicotine and makes them available for absorption through the lungs. It can also be done as a part of rituals, to induce trances and spiritual enlightenment.
The most common method of smoking today is through cigarettes, primarily industrially manufactured but also hand-rolled from loose tobacco and rolling paper. Other smoking implements include pipes, cigars, bidis, hookahs, vaporizers and bongs. It has been suggested that smoking-related disease kills one half of all long term smokers but these diseases may also be contracted by non-smokers. A 2007 report states that about 4.9 million people worldwide each year die as a result of smoking.

female sexual health
Menstruation (a period) is a major stage of puberty in girls; it's one of the many physical signs that a girl is turning into a woman.
And like a lot of the other changes associated with puberty, menstruation can be confusing. Some girls can't wait to start their periods, whereas others may feel afraid or anxious. Many girls (and guys!) don't have a complete understanding of a woman's reproductive system or what actually happens during the menstrual cycle, making the process seem even more mysterious.
When girls begin to go through puberty (usually starting between the ages of 8 and 13), their bodies and minds change in many ways. The hormones in their bodies stimulate new physical development, such as growth and breast development. About 2 to 2½ years after a girl's breasts begin to develop, she usually gets her first menstrual period.
