PDF/A is an ISO-standardized version of the Portable Document Format (PDF) specialized for use in the archiving and long-term preservation of electronic documents. PDF/A differs from PDF by prohibiting features unsuitable for long-term archiving, such as font linking (as opposed to font embedding) and encryption. The ISO requirements for PDF/A file viewers include color management guidelines, support for embedded fonts, and a user interface for reading embedded annotations.

PDF is a standard for encoding documents in an "as printed" form that is portable between systems. However, the suitability of a PDF file for archival preservation depends on options chosen when the PDF is created: most notably, whether to embed the necessary fonts for rendering the document; whether to use encryption; and whether to preserve additional information from the original document beyond what is needed to print it.
PDF/A was originally a new joint activity between the Association for Suppliers of Printing, Publishing and Converting Technologies (NPES) and the Association for Information and Image Management to develop an international standard defining the use of the Portable Document Format (PDF) for archiving documents. The goal was to address the growing need to electronically archive documents in a way that would ensure preservation of their contents over an extended period of time and ensure that those documents would be able to be retrieved and rendered with a consistent and predictable result in the future. This need exists in a wide variety of government, industry and academic areas worldwide, including legal systems, libraries, newspapers, and regulated industries.
The PDF/A standard does not define an archiving strategy or the goals of an archiving system. It identifies a "profile" for electronic documents that ensures the documents can be reproduced exactly the same way using various software in years to come. A key element to this reproducibility is the requirement for PDF/A documents to be 100% self-contained. All of the information necessary for displaying the document in the same manner is embedded in the file. This includes, but is not limited to, all content (text, raster images and vector graphics), fonts, and color information. A PDF/A document is not permitted to be reliant on information from external sources (e.g. font programs and data streams), but may include annotations (e.g. hypertext links) that link to external documents.
Level B conformance requires only that standards necessary for the reliable reproduction of a document's visual appearance be followed, while Level A conformance includes all Level B requirements in addition to features intended to improve a document's accessibility.
Additional Level A requirements:
Level A conformance was intended to increase the accessibility of conforming files for physically impaired users by allowing assistive software, such as screen readers, to more precisely extract and interpret a file's contents. A later standard, PDF/UA, was developed to eliminate what became considered some of PDF/A's shortcomings, replacing many of its general guidelines with more detailed technical specifications.
Part 2 of the standard, published on June 20, 2011, addresses some of the new features added with versions 1.5, 1.6 and 1.7 of the PDF Reference. PDF/A-1 files will not necessarily conform to PDF/A-2, and PDF/A-2 compliant files will not necessarily conform to PDF/A-1.
Part 2 of the PDF/A Standard is based on a PDF 1.7 (ISO 32000-1), rather than PDF 1.4 and offers a number of new features:
Part 2 defines three conformance levels. PDF/A-2a and PDF/A-2b correspond to conformance levels a and b in PDF/A-1. A new conformance level, PDF/A-2u, represents Level B conformance (PDF/A-2b) with the additional requirement that all text in the document have Unicode mapping.
Part 3 of the standard, published on October 15, 2012, differs from PDF/A-2 in only one regard: it allows embedding of arbitrary file formats (such as XML, CSV, CAD, word-processing documents, spreadsheet documents, and others) into PDF/A conforming documents.
Part 4 of the standard, based on PDF 2.0, is expected to be published in 2019.
A PDF/A document can be identified as such through PDF/A-specific metadata located in the "http://www.aiim.org/pdfa/ns/id/" namespace. This metadata represents a claim of conformance; in itself it does not ensure conformance:
Industry collaboration in the original PDF/A Competence Center led to the development of the Isartor Test Suite in 2007 and 2008. The test suite consists of 204 PDF files intentionally constructed to systematically fail each of the requirements for PDF/A-1b conformance, allowing developers to test the ability of their software to validate against the standard's most basic level of conformance. By mid-2009 the test suite had already made an appreciable difference in the general quality of PDF/A validation software.
The veraPDF consortium, led by the Open Preservation Foundation and the PDF Association, was created in response to the EU Commission's PREFORMA challenge to develop an open-source validator for the PDF/A format. The PDF Association launched the PDF Validation Technical Working Group in November 2014 to articulate a plan for developing an industry-supported PDF/A validator.
The veraPDF consortium subsequently won phase 2 of the PREFORMA contract in April 2015. Development continued throughout 2016, with Phase 2 completed on-schedule by December 2016. The Phase 3 testing and acceptance period concluded in July, 2017. veraPDF now covers all parts (1, 2 and 3) and conformance levels (a, b, u) of PDF/A.
veraPDF is available for installation on Windows, macOS, or Linux using a PDFBox-based or "Greenfields" PDF parser.
The PDF/A specification also states some requirements for a conforming PDF/A viewer, which must
When encountering a file that claims conformance with PDF/A, some PDF viewers will default to a special "PDF/A viewing mode" to fulfill conforming reader requirements. To take one example, Adobe Acrobat and Adobe Reader 9 include an alert to advise the user that PDF/A viewing mode has been activated. Some PDF viewers allow users to disable the PDF/A viewing mode or to remove the PDF/A information from a file.
A PDF/A document must embed all fonts in use; accordingly, a PDF/A file will often be larger than an equivalent PDF file that does not include embedded fonts.
The use of transparency is forbidden in PDF/A-1. The majority of PDF generation tools that allow for PDF/A document compliance, such as the PDF export in OpenOffice.org or PDF export tool in Microsoft Office 2007 suites, will also make any transparent images in a given document non-transparent. That restriction was removed in PDF/A-2.
Some archivists have voiced concerns that PDF/A-3, which allows arbitrary files to be embedded in PDF/A documents, could result in circumvention of memory institution procedures and restrictions on archived formats.
Converting a PDF (up to version 1.4) into a PDF/A-2 usually works as expected, except for problems with glyphs. According to the PDF Association, "Problems can occur before and/or during the generation of PDFs. A PDF/A file can be formally correct yet still have incorrect glyphs. Only a careful visual check can uncover this problem. Because generation problems also affect Unicode mapping, the problem attracts the attention when a visual check is carried out on the extracted text. In PDF/A, text/font usage is specified uniquely enough to ensure that it cannot be incorrect. If viewers or printers do not offer complete support for encoding systems, this can result in problems with regard to PDF/A." Meaning that for a document to be completely compliant with the standard, it will be correct internally, while the system used for viewing or printing the document may produce undesired results.
A document produced with OCR conversion into PDF/A-2 or PDF/A-3 doesn't support the notdefglyph flag. Therefore, this type of conversion can result in unrendered content.
Associazione Sportiva Roma (BIT: ASR, LSE: 0MT1; Rome Sport Association), commonly referred to as Roma [ˈroːma], is an Italian professional football club based in Rome. Founded by a merger in 1927, Roma have participated in the top-tier of Italian football for all of their existence except for 1951–52.
Roma have won Serie A three times, in 1941–42, 1982–83 and 2000–01, as well as winning nine Coppa Italia titles and two Supercoppa Italiana titles. In European competitions, Roma won the Inter-Cities Fairs Cup in 1960–61 and were runners-up in the 1983–84 European Cup and the 1990–91 UEFA Cup.
Fifteen players have won the FIFA World Cup while playing at Roma: Ferraris, Guaita and Masetti (1934); Donati, Monzeglio and Serantoni (1938); Bruno Conti (1982); Rudi Voller and Berthold (1990); Aldair (1994); Candela (1998); Cafu (2002); Daniele De Rossi, Simone Perrotta and Francesco Totti (2006).
Since 1953, Roma have played their home matches at the Stadio Olimpico, a venue they share with city rivals Lazio. With a capacity of over 72,000, it is the second-largest of its kind in Italy, with only the San Siro able to seat more. The club plan to move to a new stadium, though this is yet to start construction.
The club's home colours are Tyrian purple and gold, which gives Roma their nickname "I Giallorossi" ("The Yellow and Reds"). Their club badge features a she-wolf, an allusion to the founding myth of Rome.Atomic bombings of Hiroshima and Nagasaki
During the final stage of World War II, the United States detonated two nuclear weapons over the Japanese cities of Hiroshima and Nagasaki on August 6 and 9, 1945, respectively. The United States dropped the bombs after obtaining the consent of the United Kingdom, as required by the Quebec Agreement. The two bombings killed 129,000–226,000 people, most of whom were civilians. They remain the only use of nuclear weapons in the history of armed conflict.
In the final year of the war, the Allies prepared for what was anticipated to be a very costly invasion of the Japanese mainland. This undertaking was preceded by a conventional and firebombing campaign that devastated 67 Japanese cities. The war in Europe had concluded when Germany signed its instrument of surrender on May 8, 1945. As the Allies turned their full attention to the Pacific War, the Japanese faced the same fate. The Allies called for the unconditional surrender of the Imperial Japanese armed forces in the Potsdam Declaration on July 26, 1945—the alternative being "prompt and utter destruction". The Japanese ignored the ultimatum and the war continued.
By August 1945, the Allies' Manhattan Project had produced two types of atomic bombs, and the 509th Composite Group of the United States Army Air Forces (USAAF) was equipped with the specialized Silverplate version of the Boeing B-29 Superfortress that could deliver them from Tinian in the Mariana Islands. Orders for atomic bombs to be used on four Japanese cities were issued on July 25. On August 6, one of the modified B-29s dropped a uranium gun-type ("Little Boy") bomb on Hiroshima. Three days later, on August 9, a plutonium implosion ("Fat Man") bomb was dropped by another B-29 on Nagasaki. The bombs immediately devastated their targets. Over the next two to four months, the acute effects of the atomic bombings killed 90,000–146,000 people in Hiroshima and 39,000–80,000 people in Nagasaki; roughly half of the deaths in each city occurred on the first day. Large numbers of people continued to die from the effects of burns, radiation sickness, and other injuries, compounded by illness and malnutrition, for many months afterward. In both cities, most of the dead were civilians, although Hiroshima had a sizable military garrison.
Japan announced its surrender to the Allies on August 15, six days after the bombing of Nagasaki and the Soviet Union's declaration of war. On September 2, the Japanese government signed the instrument of surrender, effectively ending World War II. The effects of the bombings on the social and political character of subsequent world history and popular culture has been studied extensively, and the ethical and legal justification for the bombings is still debated to this day.Central Asia
Central Asia stretches from the Caspian Sea in the west to China in the east and from Afghanistan in the south to Russia in the north. The region consists of the former Soviet republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. It is also colloquially referred to as "the stans" as the countries generally considered to be within the region all have names ending with the Persian suffix "-stan", meaning "land of".Central Asia (2019) has a population of about 72 million, consisting of five republics: Kazakhstan (pop. 18 million), Kyrgyzstan (6 million), Tajikistan (9 million), Turkmenistan (6 million), and Uzbekistan (33 million). Afghanistan (pop. 35 million), which is a part of South Asia, is also sometimes included in Central Asia.Central Asia has historically been closely tied to its nomadic peoples and the Silk Road. It has acted as a crossroads for the movement of people, goods, and ideas between Europe, Western Asia, South Asia, and East Asia. The Silk Road connected Muslim lands with the people of Europe, India, and China. This crossroads position has intensified the conflict between tribalism and traditionalism and modernization.In pre-Islamic and early Islamic times, Central Asia was predominantly Iranian, populated by Eastern Iranian-speaking Bactrians, Sogdians, Chorasmians and the semi-nomadic Scythians and Dahae. After expansion by Turkic peoples, Central Asia also became the homeland for the Kazakhs, Uzbeks, Tatars, Turkmen, Kyrgyz, and Uyghurs; Turkic languages largely replaced the Iranian languages spoken in the area.
From the mid-19th century until almost the end of the 20th century, most of Central Asia was part of the Russian Empire and later the Soviet Union, both Slavic-majority countries, and the five former Soviet "-stans" are still home to about 7 million ethnic Russians and 500,000 Ukrainians.Cognac
Cognac ( KON-yak or KOHN-yak; French pronunciation: [kɔ.ɲak]) is a variety of brandy named after the town of Cognac, France. It is produced in the surrounding wine-growing region in the departments of Charente and Charente-Maritime.
Cognac production falls under French appellation d'origine contrôlée designation, with production methods and naming required to meet certain legal requirements. Among the specified grapes, Ugni blanc, known locally as Saint-Emilion, is most widely used. The brandy must be twice distilled in copper pot stills and aged at least two years in French oak barrels from Limousin or Tronçais. Cognac matures in the same way as whiskies and wines barrel age, and most cognacs spend considerably longer "on the wood" than the minimum legal requirement.Houston
Houston ( (listen) HEW-stən) is the most populous city in the U.S. state of Texas and the fourth most populous city in the United States, with a census-estimated population of 2.312 million in 2017. It is the most populous city in the Southern United States and on the Gulf Coast of the United States. Located in Southeast Texas near Galveston Bay and the Gulf of Mexico, it is the seat of Harris County and the principal city of the Greater Houston metropolitan area, which is the fifth most populous metropolitan statistical area (MSA) in the United States and the second most populous in Texas after the Dallas-Fort Worth MSA. With a total area of 627 square miles (1,620 km2), Houston is the eighth most expansive city in the United States (including consolidated city-counties). It is the largest city in the United States by total area, whose government is similarly not consolidated with that of a county or borough. Though primarily in Harris County, small portions of the city extend into Fort Bend and Montgomery counties.
Houston was founded by land speculators on August 30, 1836, at the confluence of Buffalo Bayou and White Oak Bayou (a point now known as Allen's Landing) and incorporated as a city on June 5, 1837. The city is named after former General Sam Houston, who was president of the Republic of Texas and had won Texas' independence from Mexico at the Battle of San Jacinto 25 miles (40 km) east of Allen's Landing. After briefly serving as the capital of the Texas Republic in the late 1830s, Houston grew steadily into a regional trading center for the remainder of the 19th century.The arrival of the 20th century saw a convergence of economic factors which fueled rapid growth in Houston, including a burgeoning port and railroad industry, the decline of Galveston as Texas' primary port following a devastating 1900 hurricane, the subsequent construction of the Houston Ship Channel, and the Texas oil boom. In the mid-20th century, Houston's economy diversified as it became home to the Texas Medical Center—the world's largest concentration of healthcare and research institutions—and NASA's Johnson Space Center, where the Mission Control Center is located.
Houston's economy has a broad industrial base in energy, manufacturing, aeronautics, and transportation. Leading in healthcare sectors and building oilfield equipment, Houston has the second most Fortune 500 headquarters of any U.S. municipality within its city limits (after New York City). The Port of Houston ranks first in the United States in international waterborne tonnage handled and second in total cargo tonnage handled. Nicknamed the "Space City", Houston is a global city, with strengths in culture, medicine, and research. The city has a population from various ethnic and religious backgrounds and a large and growing international community. Houston is the most diverse metropolitan area in Texas and has been described as the most racially and ethnically diverse major metropolis in the U.S. It is home to many cultural institutions and exhibits, which attract more than 7 million visitors a year to the Museum District. Houston has an active visual and performing arts scene in the Theater District and offers year-round resident companies in all major performing arts.Karnataka
Karnataka (Karnāṭaka) is a state in the south western region of India. It was formed on 1 November 1956, with the passage of the States Reorganisation Act. Originally known as the State of Mysore, it was renamed Karnataka in 1973. The state corresponds to the Carnatic region. The capital and largest city is Bangalore (Bengaluru).
Karnataka is bordered by the Arabian Sea to the west, Goa to the northwest, Maharashtra to the north, Telangana to the northeast, Andhra Pradesh to the east, Tamil Nadu to the southeast, and Kerala to the south. The state covers an area of 191,976 square kilometres (74,122 sq mi), or 5.83 percent of the total geographical area of India. It is the sixth largest Indian state by area. With 61,130,704 inhabitants at the 2011 census, Karnataka is the eighth largest state by population, comprising 30 districts. Kannada, one of the classical languages of India, is the most widely spoken and official language of the state alongside Konkani, Marathi, Tulu, Tamil, Telugu, Malayalam, Kodava and Beary. Karnataka also has the only 3 naturally Sanskrit-speaking districts in India.
The two main river systems of the state are the Krishna and its tributaries, the Bhima, Ghataprabha, Vedavathi, Malaprabha, and Tungabhadra in North Karnataka Sharavathi in Shivamogga , and the Kaveri and its tributaries, the Hemavati, Shimsha, Arkavati, Lakshmana Thirtha and Kabini, in the south. Most of these rivers flow out of Karnataka eastward, reaching the sea at the Bay of Bengal.
Though several etymologies have been suggested for the name Karnataka, the generally accepted one is that Karnataka is derived from the Kannada words karu and nādu, meaning "elevated land". Karu nadu may also be read as karu, meaning "black", and nadu, meaning "region", as a reference to the black cotton soil found in the Bayalu Seeme region of the state. The British used the word Carnatic, sometimes Karnatak, to describe both sides of peninsular India, south of the Krishna.With an antiquity that dates to the paleolithic, Karnataka has been home to some of the most powerful empires of ancient and medieval India. The philosophers and musical bards patronised by these empires launched socio-religious and literary movements which have endured to the present day. Karnataka has contributed significantly to both forms of Indian classical music, the Carnatic and Hindustani traditions.
The economy of Karnataka is the third-largest state economy in India with ₹15.88 lakh crore (US$220 billion) in gross domestic product and a per capita GDP of ₹174,000 (US$2,400).Limited company
In a limited company, the liability of members or subscribers of the company is limited to what they have invested or guaranteed to the company. Limited companies may be limited by shares or by guarantee. The former may be further divided in public companies and private companies. Who may become a member of a private limited company is restricted by law and by the company's rules. In contrast, anyone may buy shares in a public limited company.
Limited companies can be found in most countries, although the detailed rules governing them vary widely. It is also common for a distinction to be made between the publicly tradable companies of the plc type (for example, the German Aktiengesellschaft (AG), British PLC, Czech a.s., Italian S.p.A., Hungarian Zrt. and the Spanish, French, Polish, Greek and Romanian S.A.), and the "private" types of company (such as the German GmbH, Portuguese Ltda., British Ltd., Polish sp. z o.o., the Czech s.r.o., the French s.a.r.l., the Italian and Romanian s.r.l., Hungarian kft. and Slovak s.r.o.)List of PDF software
This is a list of links to articles on software used to manage Portable Document Format (PDF) documents. The distinction between the various functions is not entirely clear-cut; for example, some viewers allow adding of annotations, signatures, etc. Some software allows redaction, removing content irreversibly for security. Extracting embedded text is a common feature, but other applications perform optical character recognition (OCR) to convert imaged text to machine-readable form, sometimes by using an external OCR module.Madhya Pradesh
Madhya Pradesh (MP; , Hindi: [ˈmədʱjə pɾəˈdeːʃ] (listen); meaning "Central Province") is a state in central India. Its capital is Bhopal, and the largest city is Indore, with Jabalpur, Gwalior, Ujjain and Sagar being the other major cities. Nicknamed the "Heart of India" due to its geographical location, Madhya Pradesh is the second largest Indian state by area and the fifth largest state by population with over 75 million residents. It borders the states of Uttar Pradesh to the northeast, Chhattisgarh to the southeast, Maharashtra to the south, Gujarat to the west, and Rajasthan to the northwest. Its total area is 308,252 km2. Before 2000, when Chhattisgarh was a part of Madhya Pradesh, Madhya Pradesh was the largest state in India and the distance between the two furthest points inside the state, Singoli and Konta, was 1500 km. Konta is presently in Sukma district of Chhattisgarh state.
The area covered by the present-day Madhya Pradesh includes the area of the ancient Avanti Mahajanapada, whose capital Ujjain (also known as Avantika) arose as a major city during the second wave of Indian urbanisation in the sixth century BCE. Subsequently, the region was ruled by the major dynasties of India. By the early 18th century, the region was divided into several small kingdoms which were captured by the British and incorporated into Central Provinces and Berar and the Central India Agency. After India's independence, Madhya Pradesh state was created with Nagpur as its capital: this state included the southern parts of the present-day Madhya Pradesh and northeastern portion of today's Maharashtra. In 1956, this state was reorganised and its parts were combined with the states of Madhya Bharat, Vindhya Pradesh and Bhopal to form the new Madhya Pradesh state, the Marathi-speaking Vidarbha region was removed and merged with the then Bombay State. This state was the largest in India by area until 2000, when its southeastern Chhattisgarh region was made as a separate state.
Rich in mineral resources, MP has the largest reserves of diamond and copper in India. More than 30% of its area is under forest cover. Its tourism industry has seen considerable growth, with the state topping the National Tourism Awards in 2010–11. In recent years, the state's GDP growth has been above the national average.PDF
The Portable Document Format (PDF) is a file format developed by Adobe in the 1990s to present documents, including text formatting and images, in a manner independent of application software, hardware, and operating systems. Based on the PostScript language, each PDF file encapsulates a complete description of a fixed-layout flat document, including the text, fonts, vector graphics, raster images and other information needed to display it. PDF was standardized as an open format, ISO 32000, in 2008, and no longer requires any royalties for its implementation.Today, PDF files may contain a variety of content besides flat text and graphics including logical structuring elements, interactive elements such as annotations and form-fields, layers, rich media (including video content) and three dimensional objects using U3D or PRC, and various other data formats. The PDF specification also provides for encryption and digital signatures, file attachments and metadata to enable workflows requiring these features.Pakistan
Pakistan (Urdu: پاکِستان), officially the Islamic Republic of Pakistan (Urdu: اِسلامی
جمہوریہ پاکِستان), is a country in South Asia. It is the world’s sixth-most populous country with a population exceeding 212,742,631 people. In area, it is the 33rd-largest country, spanning 881,913 square kilometres (340,509 square miles). Pakistan has a 1,046-kilometre (650-mile) coastline along the Arabian Sea and Gulf of Oman in the south and is bordered by India to the east, Afghanistan to the west, Iran to the southwest, and China in the far northeast. It is separated narrowly from Tajikistan by Afghanistan's Wakhan Corridor in the northwest, and also shares a maritime border with Oman.
The territory that now constitutes Pakistan was the site of several ancient cultures and intertwined with the history of the broader Indian subcontinent. The ancient history involves the Neolithic site of Mehrgarh and the Bronze Age Indus Valley Civilisation, and was later home to kingdoms ruled by people of different faiths and cultures, including Hindus, Indo-Greeks, Muslims, Turco-Mongols, Afghans and Sikhs. The area has been ruled by numerous empires and dynasties, including the Persian Achaemenid Empire, Alexander III of Macedon, the Seleucid Empire, the Indian Maurya Empire, the Gupta Empire, the Arab Umayyad Caliphate, the Delhi Sultanate, the Mongol Empire, the Mughal Empire, the Afghan Durrani Empire, the Sikh Empire (partially) and, most recently, the British Empire. Pakistan is the only country to have been created in the name of Islam. It is an ethnically and linguistically diverse country, with a similarly diverse geography and wildlife. Initially a dominion, Pakistan adopted a constitution in 1956, becoming an Islamic republic. An ethnic civil war and Indian military intervention in 1971 resulted in the secession of East Pakistan as the new country of Bangladesh. In 1973, Pakistan adopted a new constitution which stipulated that all laws are to conform to the injunctions of Islam as laid down in the Quran and Sunnah.A regional and middle power, Pakistan has the sixth-largest standing armed forces in the world and is also a nuclear power as well as a declared nuclear-weapons state, the second in South Asia and the only nation in the Muslim world to have that status. Pakistan has a semi-industrialised economy with a well-integrated agriculture sector and a growing services sector. It is ranked among the emerging and growth-leading economies of the world, and is backed by one of the world's largest and fastest-growing middle class. Pakistan's political history since independence has been characterized by periods of military rule, political instability and conflicts with India. The country continues to face challenging problems, including overpopulation, terrorism, poverty, illiteracy, and corruption. Pakistan is a member of the UN, the Shanghai Cooperation Organisation, the OIC, the Commonwealth of Nations, the SAARC and the Islamic Military Counter Terrorism Coalition.Paul the Apostle
Paul the Apostle (Latin: Paulus; Greek: Παῦλος, translit. Paulos; Coptic: ⲡⲁⲩⲗⲟⲥ; c. 5 – c. 64 or 67), commonly known as Saint Paul and also known by his Jewish name Saul of Tarsus (Hebrew: שאול התרסי, translit. Sha'ūl ha-Tarsī; Greek: Σαῦλος Ταρσεύς, translit. Saũlos Tarseús), was an apostle (although not one of the Twelve Apostles) who taught the gospel of Christ to the first-century world. Paul is generally considered one of the most important figures of the Apostolic Age and in the mid-30s to the mid-50s AD he founded several churches in Asia Minor and Europe. He took advantage of his status as both a Jew and a Roman citizen to minister to both Jewish and Roman audiences.
According to writings in the New Testament and prior to his conversion, Paul was dedicated to persecuting the early disciples of Jesus in the area of Jerusalem. In the narrative of the Acts of the Apostles (often referred to simply as Acts), Paul was traveling on the road from Jerusalem to Damascus on a mission to "arrest them and bring them back to Jerusalem" when the resurrected Jesus appeared to him in a great light. He was struck blind, but after three days his sight was restored by Ananias of Damascus and Paul began to preach that Jesus of Nazareth is the Jewish Messiah and the Son of God. Approximately half of the book of Acts deals with Paul's life and works.
Thirteen of the twenty-seven books in the New Testament have traditionally been attributed to Paul. Seven of the Pauline epistles are undisputed by scholars as being authentic, with varying degrees of argument about the remainder. Pauline authorship of the Epistle to the Hebrews is not asserted in the Epistle itself and was already doubted in the 2nd and 3rd centuries. It was almost unquestioningly accepted from the 5th to the 16th centuries that Paul was the author of Hebrews, but that view is now almost universally rejected by scholars. The other six are believed by some scholars to have come from followers writing in his name, using material from Paul's surviving letters and letters written by him that no longer survive. Other scholars argue that the idea of a pseudonymous author for the disputed epistles raises many problems.Today, Paul's epistles continue to be vital roots of the theology, worship and pastoral life in the Catholic and Protestant traditions of the West, as well as the Orthodox traditions of the East. Paul's influence on Christian thought and practice has been characterized as being as "profound as it is pervasive", among that of many other apostles and missionaries involved in the spread of the Christian faith. Augustine of Hippo developed Paul's idea that salvation is based on faith and not "works of the law". Martin Luther's interpretation of Paul's writings influenced Luther's doctrine of sola fide.Pornography
Pornography (often abbreviated porn) is the portrayal of sexual subject matter for the exclusive purpose of sexual arousal. Pornography may be presented in a variety of media, including books, magazines, postcards, photographs, sculpture, drawing, painting, animation, sound recording, writing, film, video, and video games. The term applies to the depiction of the act rather than the act itself, and so does not include live exhibitions like sex shows and striptease. The primary subjects of present-day pornographic depictions are pornographic models, who pose for still photographs, and pornographic actors or "porn stars", who perform in pornographic films. If dramatic skills are not involved, a performer in pornographic media may also be called a model.
Various groups within society have considered depictions of a sexual nature immoral, addictive, and noxious, labeling them pornographic, and attempting to have them suppressed under obscenity and other laws, with varying degrees of success. Such works have also often been subject to censorship and other legal restraints to publication, display, or possession, leading in many cases to their loss. Such grounds, and even the definition of pornography, have differed in various historical, cultural, and national contexts.Social attitudes towards the discussion and presentation of sexuality have become more tolerant in Western countries, and legal definitions of obscenity have become more limited, notably beginning in 1969 with Blue Movie by Andy Warhol, the first adult erotic film depicting explicit sex to receive wide theatrical release in the United States, and the subsequent Golden Age of Porn (1969-1984), leading to an industry for the production and consumption of pornography in the latter half of the 20th century. The introduction of home video and the Internet saw a boom in the worldwide porn industry that generates billions of dollars annually. Commercialized pornography accounts for over US$2.5 billion in the United States alone, including the production of various media and associated products and services. The general porn industry is between $10-$12 billion in the U.S. In 2006, the world pornography revenue was 97 billion dollars. This industry employs thousands of performers along with support and production staff. It is also followed by dedicated industry publications and trade groups as well as the mainstream press, private organizations (watchdog groups), government agencies, and political organizations. More recently, sites such as Pornhub, RedTube, and YouPorn, in addition to much pirated porn posted by individuals, have served as repositories for home-made or semi-professional pornography, made available free by its creators (who could be called exhibitionists). They present a significant challenge to the commercial pornographic film industry.
Irrespective of the legal or social view of pornography, it has been used in a number of contexts. It is used, for example, at fertility clinics to stimulate sperm donors. Some couples use pornography at times for variety and to create a sexual interest or as part of foreplay. There is also some evidence that pornography can be used to treat voyeurism.Richard Nixon
Richard Milhous Nixon (January 9, 1913 – April 22, 1994) was the 37th president of the United States from 1969 to 1974. He had previously served as the 36th vice president of the United States from 1953 to 1961, and prior to that as both a U.S. representative and senator from California.
Nixon was born in Yorba Linda, California. After completing his undergraduate studies at Whittier College, he graduated from Duke University School of Law in 1937 and returned to California to practice law. He and his wife Pat moved to Washington in 1942 to work for the federal government. He subsequently served on active duty in the U.S. Navy Reserve during World War II. Nixon was elected to the House of Representatives in 1946 and to the Senate in 1950. His pursuit of the Hiss Case established his reputation as a leading anti-communist and elevated him to national prominence. He was the running mate of Dwight D. Eisenhower, the Republican Party presidential nominee in the 1952 election. Nixon served for eight years as Vice President, becoming the second-youngest vice president in history at age 40. He waged an unsuccessful presidential campaign in 1960, narrowly losing to John F. Kennedy, and lost a race for governor of California to Pat Brown in 1962. In 1968, he ran for the presidency again and was elected, defeating incumbent Vice President Hubert Humphrey.
Nixon ended American involvement in the war in Vietnam in 1973 and brought the American POWs home, and ended the military draft. Nixon's visit to China in 1972 eventually led to diplomatic relations between the two nations and he initiated détente and the Anti-Ballistic Missile Treaty with the Soviet Union the same year. His administration generally transferred power from Washington D.C. to the states. He imposed wage and price controls for ninety days, enforced desegregation of Southern schools, established the Environmental Protection Agency and began the War on Cancer. Nixon also presided over the Apollo 11 moon landing, which signaled the end of the moon race. He was reelected in one of the largest electoral landslides in U.S. history in 1972 when he defeated George McGovern.
In his second term, Nixon ordered an airlift to resupply Israeli losses in the Yom Kippur War, resulting in the restart of the Middle East peace process and an oil crisis at home. The Nixon administration supported a coup in Chile that ousted the government of Salvador Allende and propelled Augusto Pinochet to power. By late 1973, the Watergate scandal escalated, costing Nixon much of his political support. On August 9, 1974, he resigned in the face of almost certain impeachment and removal from office—the only time a U.S. president has done so. After his resignation, he was issued a controversial pardon by his successor, Gerald Ford. In 20 years of retirement, Nixon wrote nine books and undertook many foreign trips, helping to rehabilitate his image into that of an elder statesman. He suffered a debilitating stroke on April 18, 1994 and died four days later at the age of 81.Scientology
Scientology is a body of religious beliefs and practices launched in May 1952 by American author L. Ron Hubbard (1911–86). Hubbard initially developed a program of ideas called Dianetics, which was distributed through the Dianetics Foundation. The foundation soon entered bankruptcy, and Hubbard lost the rights to his seminal publication Dianetics: The Modern Science of Mental Health in 1952. He then recharacterized the subject as a religion and renamed it Scientology, retaining the terminology, doctrines, the E-meter, and the practice of auditing. Within a year, he regained the rights to Dianetics and retained both subjects under the umbrella of the Church of Scientology.Hubbard describes the etymology of the word "Scientology" as coming from the Latin word scio, meaning know or distinguish, and the Greek word logos, meaning "the word or outward form by which the inward thought is expressed and made known". Hubbard writes, "thus, Scientology means knowing about knowing, or science of knowledge".Hubbard's groups have encountered considerable opposition and controversy. In January 1951, the New Jersey Board of Medical Examiners brought proceedings against Dianetics Foundation on the charge of teaching medicine without a license. Hubbard's followers engaged in a program of criminal infiltration of the U.S. government.Hubbard-inspired organizations and their classification are often a point of contention. Germany classifies Scientology groups as an "anti-constitutional sect". In France, they have been classified as a dangerous cult by some parliamentary reports.Transparency (graphic)
Transparency is possible in a number of graphics file formats. The term transparency is used in various ways by different people, but at its simplest there is "full transparency" i.e. something that is completely invisible. Only part of a graphic should be fully transparent, or there would be nothing to see. More complex is "partial transparency" or "translucency" where the effect is achieved that a graphic is partially transparent in the same way as colored glass. Since ultimately a printed page or computer or television screen can only be one color at a point, partial transparency is always simulated at some level by mixing colors. There are many different ways to mix colors, so in some cases transparency is ambiguous.
In addition, transparency is often an "extra" for a graphics format, and some graphics programs will ignore the transparency.
Raster file formats that support transparency include GIF, PNG, BMP, TIFF, and JPEG 2000, through either a transparent color or an alpha channel.
Most vector formats implicitly support transparency because they simply avoid putting any objects at a given point. This includes EPS and WMF. For
vector graphics this may not strictly be seen as transparency, but it requires
much of the same careful programming as transparency in raster formats.
More complex vector formats may allow transparency combinations between the elements within the graphic, as well as that above. This includes SVG and PDF.
A suitable raster graphics editor shows transparency by a special pattern, e.g. a checkerboard pattern.Uranus
Uranus (from the Latin name "Ūranus" for the Greek god Οὐρανός) is the seventh planet from the Sun. It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn. For this reason, scientists often classify Uranus and Neptune as "ice giants" to distinguish them from the gas giants. Uranus' atmosphere is similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons. It is the coldest planetary atmosphere in the Solar System, with a minimum temperature of 49 K (−224 °C; −371 °F), and has a complex, layered cloud structure with water thought to make up the lowest clouds and methane the uppermost layer of clouds. The interior of Uranus is mainly composed of ices and rock.Like the other giant planets, Uranus has a ring system, a magnetosphere, and numerous moons. The Uranian system has a unique configuration because its axis of rotation is tilted sideways, nearly into the plane of its solar orbit. Its north and south poles, therefore, lie where most other planets have their equators. In 1986, images from Voyager 2 showed Uranus as an almost featureless planet in visible light, without the cloud bands or storms associated with the other giant planets. Observations from Earth have shown seasonal change and increased weather activity as Uranus approached its equinox in 2007. Wind speeds can reach 250 metres per second (900 km/h; 560 mph).Uranus is the only planet whose name is derived directly from a figure from Greek mythology, from the Latinised version of the Greek god of the sky Ouranos.Wales
Wales (Welsh: Cymru [ˈkəmri] (listen)) is a country that is part of the United Kingdom and the island of Great Britain. It is bordered by England to the east, the Irish Sea to the north and west, and the Bristol Channel to the south. It had a population in 2011 of 3,063,456 and has a total area of 20,779 km2 (8,023 sq mi). Wales has over 1,680 miles (2,700 km) of coastline and is largely mountainous, with its higher peaks in the north and central areas, including Snowdon (Yr Wyddfa), its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate.
Welsh national identity emerged among the Britons after the Roman withdrawal from Britain in the 5th century, and Wales is regarded as one of the modern Celtic nations. Llywelyn ap Gruffudd's death in 1282 marked the completion of Edward I of England's conquest of Wales, though Owain Glyndŵr briefly restored independence to Wales in the early 15th century. The whole of Wales was annexed by England and incorporated within the English legal system under the Laws in Wales Acts 1535 and 1542. Distinctive Welsh politics developed in the 19th century. Welsh liberalism, exemplified in the early 20th century by Lloyd George, was displaced by the growth of socialism and the Labour Party. Welsh national feeling grew over the century; Plaid Cymru was formed in 1925 and the Welsh Language Society in 1962. Established under the Government of Wales Act 1998, the National Assembly for Wales holds responsibility for a range of devolved policy matters.
At the dawn of the Industrial Revolution, development of the mining and metallurgical industries transformed the country from an agricultural society into an industrial nation; the South Wales Coalfield's exploitation caused a rapid expansion of Wales' population. Two-thirds of the population live in South Wales, including Cardiff, Swansea, Newport and the nearby valleys. Now that the country's traditional extractive and heavy industries have gone or are in decline, Wales' economy depends on the public sector, light and service industries and tourism.
Although Wales closely shares its political and social history with the rest of Great Britain, and a majority of the population in most areas speaks English as a first language, the country has retained a distinct cultural identity and is officially bilingual. Over 560,000 Welsh language speakers live in Wales, and the language is spoken by a majority of the population in parts of the north and west. From the late 19th century onwards, Wales acquired its popular image as the "land of song", in part due to the eisteddfod tradition. At many international sporting events, such as the FIFA World Cup, Rugby World Cup and the Commonwealth Games, Wales has its own national teams, though at the Olympic Games, Welsh athletes compete as part of a Great Britain team. Rugby union is seen as a symbol of Welsh identity and an expression of national consciousness.Yellowstone National Park
Yellowstone National Park is an American national park located in Wyoming, Montana, and Idaho. It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially Old Faithful geyser, one of its most popular features. It has many types of ecosystems, but the subalpine forest is the most abundant. It is part of the South Central Rockies forests ecoregion.
Native Americans have lived in the Yellowstone region for at least 11,000 years. Aside from visits by mountain men during the early-to-mid-19th century, organized exploration did not begin until the late 1860s. Management and control of the park originally fell under the jurisdiction of the Secretary of the Interior, the first being Columbus Delano. However, the U.S. Army was subsequently commissioned to oversee management of Yellowstone for a 30-year period between 1886 and 1916. In 1917, administration of the park was transferred to the National Park Service, which had been created the previous year. Hundreds of structures have been built and are protected for their architectural and historical significance, and researchers have examined more than a thousand archaeological sites.
Yellowstone National Park spans an area of 3,468.4 square miles (8,983 km2), comprising lakes, canyons, rivers and mountain ranges. Yellowstone Lake is one of the largest high-elevation lakes in North America and is centered over the Yellowstone Caldera, the largest supervolcano on the continent. The caldera is considered an active volcano. It has erupted with tremendous force several times in the last two million years. Half of the world's geysers and hydrothermal features are in Yellowstone, fueled by this ongoing volcanism. Lava flows and rocks from volcanic eruptions cover most of the land area of Yellowstone. The park is the centerpiece of the Greater Yellowstone Ecosystem, the largest remaining nearly-intact ecosystem in the Earth's northern temperate zone. In 1978, Yellowstone was named a UNESCO World Heritage Site.
Hundreds of species of mammals, birds, fish, and reptiles have been documented, including several that are either endangered or threatened. The vast forests and grasslands also include unique species of plants. Yellowstone Park is the largest and most famous megafauna location in the contiguous United States. Grizzly bears, wolves, and free-ranging herds of bison and elk live in this park. The Yellowstone Park bison herd is the oldest and largest public bison herd in the United States. Forest fires occur in the park each year; in the large forest fires of 1988, nearly one third of the park was burnt. Yellowstone has numerous recreational opportunities, including hiking, camping, boating, fishing and sightseeing. Paved roads provide close access to the major geothermal areas as well as some of the lakes and waterfalls. During the winter, visitors often access the park by way of guided tours that use either snow coaches or snowmobiles.
