74-429: The palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone . They contribute to the walls of three cavities: the floor and lateral walls of the nasal cavity, the roof of the mouth, and the floor of the orbits. They help to form the pterygopalatine and pterygoid fossae , and the inferior orbital fissures . Each palatine bone somewhat resembles

148-465: A "Public Domain Day" was initially informal; the earliest known mention was in 2004 by Wallace McLean (a Canadian public domain activist), with support for the idea echoed by Lawrence Lessig . As of 1 January 2010, there is as Public Domain Day website lists the authors whose works are entering the public domain. There are activities in countries around the world by various organizations all under

222-529: A copyright has expired depends on an examination of the copyright in its source country. In most countries that are signatories to the Berne Convention , copyright term is based on the life of the author, and extends to 50 or 70 years beyond the death of the author. (See List of copyright terms of countries .) In the United States, determining whether a work has entered the public domain or

296-529: A mobile articulation with the cranium . There are numerous variations amongst mammals, amphibians and other species. For example, the palatine bone in many amphibians such as the rough-skinned newt manifests as a distinct V-shaped structure. In the case of cat species, the horizontal and a vertical elements join at a 45-degree angle. [REDACTED] This article incorporates text in the public domain from page 166 of the 20th edition of Gray's Anatomy (1918) Nasal cavity The nasal cavity

370-457: A work may be subject to rights in one country and be in the public domain in another. Some rights depend on registrations on a country-by-country basis, and the absence of registration in a particular country, if required, gives rise to public-domain status for a work in that country. The term public domain may also be interchangeably used with other imprecise or undefined terms such as the public sphere or commons , including concepts such as

444-475: A work, as well as other forms of transformation or adaptation. Copyrighted works may not be used for derivative works without permission from the copyright owner, while public domain works can be freely used for derivative works without permission. Artworks that are public domain may also be reproduced photographically or artistically or used as the basis of new, interpretive works. Works derived from public domain works can be copyrighted. Once works enter into

518-619: Is a combination of the copyright symbol , which acts as copyright notice , with the international 'no' symbol . The Europeana databases use it, and for instance on the Wikimedia Commons in February 2016 2.9 million works (~10% of all works) are listed with the mark. The underlying idea that is expressed or manifested in the creation of a work generally cannot be the subject of copyright law (see idea–expression divide ). Mathematical formulae will therefore generally form part of

592-512: Is a film that was never under copyright, was released to public domain by its author, or whose copyright has expired. All films in the United States before January 1st, 1929 have been entered in the public domain. Pamela Samuelson has identified eight "values" that can arise from information and works in the public domain. Possible values include: Derivative works include translations , musical arrangements , and dramatizations of

666-399: Is a large, air-filled space above and behind the nose in the middle of the face . The nasal septum divides the cavity into two cavities, also known as fossae . Each cavity is the continuation of one of the two nostrils . The nasal cavity is the uppermost part of the respiratory system and provides the nasal passage for inhaled air from the nostrils to the nasopharynx and rest of

740-622: Is better known as aspirin in the United States—a generic term. In Canada, however, Aspirin , with an uppercase A, is still a trademark of the German company Bayer , while aspirin, with a lowercase "a", is not. Bayer lost the trademark in the United States, the UK and France after World War I, as part of the Treaty of Versailles . So many copycat products entered the marketplace during the war that it

814-401: Is divided into two segments: the respiratory segment and the olfactory segment. There is a rich blood supply to the nasal cavity. Blood supply comes from branches of both the internal and external carotid artery , including branches of the facial artery and maxillary artery . The named arteries of the nose are: Innervation of the nasal cavity responsible for the sense of smell is via

888-417: Is formed in its upper third to one half by the nasal bone and more inferiorly by the junctions of the upper lateral cartilage and nasal septum. Connective tissue and skin cover the bony and cartilaginous components of the nasal dorsum . The floor of the nasal cavities, which also form the roof of the mouth, is made up by the bones of the hard palate: the horizontal plate of the palatine bone posteriorly and

962-497: Is in the public domain due to an unrenewed copyright. Courts in different jurisdictions have come to different conclusions as to whether the reproduction of a public domain work gains its own rights protection, or whether it to is in the public domain. In a German 2016 case, the Reiss-Engelhorn-Museen , an art museum, sued Wikimedia Commons over photographs uploaded to the database depicting pieces of art in

1036-479: Is not possible to waive those rights, but only the rights related to the exploitation of the work. A solution to this issue (as found in the Creative Commons Zero dedication) is to interpret the license by setting "three different layers of action. First, the right holder waives any copyright and related rights that can be waived in accordance with the applicable law. Secondly, if there are rights that

1110-513: Is only registered in reference to food products (a trademark claim is made within a particular field). Such defences have failed in the United Kingdom. Public Domain Day is an observance of when copyrighted works expire and works enter into the public domain. This legal transition of copyright works into the public domain usually happens every year on 1 January based on the individual copyright laws of each country . The observance of

1184-506: Is required to grant permission (" Permission culture "). There are multiple licenses which aim to release works into the public domain. In 2000 the WTFPL was released as a public domain like software license . Creative Commons (created in 2002 by Lawrence Lessig , Hal Abelson , and Eric Eldred ) has introduced several public-domain-like licenses, called Creative Commons licenses . These give authors of works (that would qualify for copyright)

1258-411: Is still under copyright depends upon what the law or regulation was at creation, and whether new regulations have grandfathered in certain older works. Because copyright terms shifted over the course of the 20th century from a fixed-term based on first publication, with a possible renewal term , to a term extending to 50, then 70, years after the death of the author. The claim that "pre-1929 works are in

1332-718: Is the Zero Clause BSD license , released in 2006 and aimed at software. In October 2014, the Open Knowledge Foundation recommends the Creative Commons CC0 license to dedicate content to the public domain, and the Open Data Commons Public Domain Dedication and License (PDDL) for data. In most countries, the term of rights for patents is 20 years, after which the invention becomes part of

1406-422: The public sphere or commons , including concepts such as the "commons of the mind", the "intellectual commons", and the "information commons". A public-domain book is a book with no copyright, a book that was created without a license, or a book where its copyrights expired or have been forfeited. In most countries the term of protection of copyright expires on the first day of January, 70 years after

1480-528: The German Copyright Act , stating that since the photographer needed to make practical decisions about the photograph that it was protected material. In contrast, in the 1999 US case Bridgeman Art Library v. Corel Corp. , the court ruled that exact photographic copies of public domain images could not be protected by copyright in the United States because the copies lack originality . In some countries, certain works may never fully lapse into

1554-546: The Music of Mesopotamia system, was created 4,000 years ago. Guido of Arezzo introduced Latin musical notation in the 10th century. This laid the foundation for the preservation of global music in the public domain, a distinction formalized alongside copyright systems in the 17th century. Musicians copyrighted their publications of musical notation as literary writings, but performing copyrighted pieces and creating derivative works were not restricted by early copyright laws.

1628-432: The esophagus and is digested in the stomach. The nasal cavity also houses the sense of smell and contributes greatly to taste sensation through its posterior communication with the mouth via the choanae . Diseases of the nasal cavity include viral , bacterial and fungal infections, nasal cavity tumors , both benign and much more often malignant, as well as inflammations of the nasal mucosa . Many problems can affect

1702-457: The labyrinth of ethmoid and the inferior concha . The paranasal sinuses are connected to the nasal cavity through small orifices called ostia . Most of these ostia communicate with the nose through the lateral nasal wall, via a semi-lunar depression in it known as the semilunar hiatus . The hiatus is bound laterally by a projection known as the uncinate process . This region is called the ostiomeatal complex . The roof of each nasal cavity

1776-407: The lateral nasal cartilage , and posteriorly by the nasal sill. The internal nasal valve is bounded laterally by the caudal border of the lateral nasal cartilage, medially by the dorsal nasal septum , and inferiorly by the anterior border of the inferior turbinate . The internal nasal valve is the narrowest region of the nasal cavity and is the primary site of nasal resistance. The nasal cavity

1850-431: The mucous glands is carried on postganglionic parasympathetic nerve fibers originating from the facial nerve . The two nasal cavities condition the air to be received by the other areas of the respiratory tract . Owing to the large surface area provided by the nasal conchae (also known as turbinates), the air passing through the nasal cavity is warmed or cooled to within 1 degree of body temperature . In addition,

1924-401: The nostrils of the vestibule are the nasal hair , which filter dust and other matter that are breathed in. The back of the cavity blends, via the choanae , into the nasopharynx . The nasal cavity is divided in two by the vertical nasal septum . On the side of each nasal cavity are three horizontal outgrowths called nasal conchae (singular "concha") or turbinates. These turbinates disrupt

1998-417: The olfactory nerve , which sends microscopic fibers from the olfactory bulb through the cribriform plate to reach the top of the nasal cavity. General sensory innervation is by branches of the trigeminal nerve (V 1 and V 2 ): The nasal cavity is innervated by autonomic fibers. Sympathetic innervation to the blood vessels of the mucosa causes them to constrict , while the control of secretion by

2072-409: The respiratory tract . The paranasal sinuses surround and drain into the nasal cavity. The term "nasal cavity" can refer to each of the two cavities of the nose, or to the two sides combined. The lateral wall of each nasal cavity mainly consists of the maxilla . However, there is a deficiency that is compensated for by the perpendicular plate of the palatine bone , the medial pterygoid plate ,

2146-502: The "commons of the mind", the "intellectual commons", and the "information commons". Although the term domain did not come into use until the mid-18th century, the concept can be traced back to the ancient Roman law , "as a preset system included in the property right system". The Romans had a large proprietary rights system where they defined "many things that cannot be privately owned" as res nullius , res communes , res publicae and res universitatis . The term res nullius

2220-427: The "personality" of the person drawing them, are not subject to copyright protection. This is separate from the patent rights just mentioned. A trademark registration may remain in force indefinitely, or expire without specific regard to its age. For a trademark registration to remain valid, the owner must continue to use it. In some circumstances, such as disuse, failure to assert trademark rights, or common usage by

In countries where they cannot be waived they will remain into full effect in accordance to the applicable law (think of France, Spain or Italy where moral rights cannot be waived)." The same occurs in Switzerland. The Unlicense , published around 2010, has a focus on an anti-copyright message. The Unlicense offers a public domain waiver text with a fallback public domain-like license inspired by permissive licenses but without attribution. Another option

2368-482: The US, foreign-sourced works and US-sourced works are now treated differently, with foreign-sourced works remaining under copyright regardless of compliance with formalities, while domestically sourced works may be in the public domain if they failed to comply with then-existing formalities requirements—a situation described as odd by some scholars, and unfair by some US-based rightsholders. Works of various governments around

2442-565: The US, works could be easily given into the public domain by just releasing it without an explicit copyright notice . With the Berne Convention Implementation Act of 1988 (and the earlier Copyright Act of 1976 , which went into effect in 1978), all works were by default copyright protected and needed to be actively given into public domain by a waiver statement/ anti-copyright can call notice . Not all legal systems have processes for reliably donating works to

2516-464: The ability to decide which protections they would like to place on their material. As copyright is the default license for new material, Creative Commons licenses offer authors a variety of options to designate their work under whichever license they wish, as long as this does not violate standing copyright law. For example, a CC BY license allows for re-users to distribute, remix, adapt, and build upon material, while also agreeing to provide attribution to

2590-401: The air is humidified, and dust and other particulate matter is removed by nasal hair in the nostrils. The entire mucosa of the nasal cavity is covered by a blanket of mucus, which lies superficial to the microscopic cilia and also filters inspired air. The cilia of the respiratory epithelium move the secreted mucus and particulate matter posteriorly towards the pharynx where it passes into

2664-406: The airflow, directing air toward the olfactory epithelium on the surface of the turbinates and the septum. The vomeronasal organ is located at the back of the septum and has a role in pheromone detection. The nasal cavity has a nasal valve area that includes an external nasal valve and an internal nasal valve . The external nasal valve is bounded medially by the columella , laterally by

2738-603: The author in any of these cases. In 2009 the Creative Commons released the CC0 , which was created for compatibility with law domains which have no concept of dedicating into public domain . This is achieved by a public domain waiver statement and a fallback all-permissive license, in case the waiver is not possible. Unlike in the US, where author's moral rights are generally not specifically regulated, in some countries where moral rights are protected separately in law it

2812-674: The construction of the idea of "public domain" sprouted from the concepts of res communes , res publicae , and res universitatis in early Roman law. When the first early copyright law was originally established in Britain with the Statute of Anne in 1710, public domain did not appear. However, similar concepts were developed by British and French jurists in the 18th century. Instead of "public domain", they used terms such as publici juris or propriété publique to describe works that were not covered by copyright law. The phrase "fall in

2886-405: The date and location of publishing, unless explicitly released beforehand. The Musopen project records music in the public domain for the purposes of making the music available to the general public in a high-quality audio format. Online musical archives preserve collections of classical music recorded by Musopen and offer them for download/distribution as a public service. A public-domain film

2960-470: The death of the latest living author. The longest copyright term is in Mexico, which has life plus 100 years for all deaths since July 1928. A notable exception is the United States, where every book and tale published before 1929 is in the public domain; US copyrights last for 95 years for books originally published between 1929 and 1978 if the copyright was properly registered and maintained. For example:

3034-430: The floor of the nasal cavity; anteriorly, they join with the maxillae. The two horizontal plates articulate with each other at the posterior part of the median palatine suture and more anteriorly with the maxillae at the transverse palatine suture. The human palatine articulates with six bones: the sphenoid , ethmoid , maxilla , inferior nasal concha , vomer and opposite palatine. There are two important foramina in

3108-501: The former of which refers to melody, notation or lyrics created by a composer or lyricist, including sheet music, and the latter referring to a recording performed by an artist, including a CD, LP, or digital sound file. Musical compositions fall under the same general rules as other works, and anything published before 1925 is considered public domain. Sound recordings, on the other hand, are subject to different rules and are not eligible for public domain status until 2021–2067, depending on

3182-419: The launching point for transformative retellings such as Tom Stoppard 's Rosencrantz and Guildenstern Are Dead and Troma Entertainment 's Tromeo and Juliet . Marcel Duchamp's L.H.O.O.Q. is a derivative of Leonardo da Vinci's Mona Lisa , one of thousands of derivative works based on the public domain painting. The 2018 film A Star is Born is a remake of the 1937 film of the same name , which

3256-421: The lesser palatine nerve and blood vessels to the soft palate and tonsils. Both foramina are openings of the pterygopalatine canal that carries the descending palatine nerves and blood vessels from the pterygopalatine fossa to the palate. The sphenopalatine foramen is the opening between the sphenoid bone and orbital processes of the palatine bone; it opens into the nasal cavity and gives passage to branches from

3330-410: The letter L, and consists of a horizontal plate , a perpendicular plate , and three projecting processes—the pyramidal process , which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes , which surmount the vertical part, and are separated by a deep notch, the sphenopalatine notch. The two plates form the posterior part of the hard palate and

A parallel development has occurred to varying degrees in many living reptiles, reaching its greatest extent in crocodilians . In birds , the palatine bones remain separate, long the sides of the rear part of the upper jaw, and typically have

3478-480: The museum. The museum claimed that the photos were taken by their staff, and that photography within the museum by visitors was prohibited. Therefore, photos taken by the museum, even of material that itself had fallen into the public domain, were protected by copyright law and would need to be removed from the Wikimedia image repository. The court ruled that the photographs taken by the museum would be protected under

3552-637: The nose, including: Public domain The public domain ( PD ) consists of all the creative work to which no exclusive intellectual property rights apply. Those rights may have expired, been forfeited, expressly waived , or may be inapplicable. Because no one holds the exclusive rights, anyone can legally use or reference those works without permission. As examples, the works of William Shakespeare , Ludwig van Beethoven , Miguel de Cervantes , Zoroaster , Lao Zi , Confucius , Aristotle , L. Frank Baum , Leonardo da Vinci and Georges Méliès are in

3626-622: The ocean of the public domain." Copyright law differs by country, and the American legal scholar Pamela Samuelson has described the public domain as being "different sizes at different times in different countries". Definitions of the boundaries of the public domain in relation to copyright, or intellectual property more generally, regard the public domain as a negative space; that is, it consists of works that are no longer in copyright term or were never protected by copyright law. According to James Boyle this definition underlines common usage of

3700-417: The palatine bones that transmit nerves and blood vessels to this region: the greater and lesser palatine. The larger greater palatine foramen is located in the posterolateral region of each of the palatine bones, usually at the apex of the maxillary third molar. The greater palatine foramen transmits the greater palatine nerve and blood vessels. A smaller opening nearby, the lesser palatine foramen , transmits

3774-401: The palatine process of the maxilla anteriorly. The most anterior part of the nasal cavity is the nasal vestibule . The vestibule is enclosed by the nasal cartilages and lined by the same epithelium of the skin (stratified squamous, keratinized). Within the vestibule, this changes into the typical respiratory epithelium that lines the rest of the nasal cavity and respiratory tract . Inside

3848-403: The pterygopalatine ganglion and the sphenopalatine artery from the maxillary artery. In bony fish , the palatine bone consists of the perpendicular plate only, lying on the inner edge of the maxilla. The lower surface of the bone may bear several teeth, forming a second row behind those of the maxilla; in many cases, these are actually larger than the maxillary teeth. Although a similar pattern

3922-518: The public domain (see waiver ); examples include reference implementations of cryptographic algorithms, and the image-processing software ImageJ (created by the National Institutes of Health ). The term public domain is not normally applied to situations where the creator of a work retains residual rights, in which case use of the work is referred to as "under license" or "with permission". As rights vary by country and jurisdiction,

3996-419: The public domain either by virtue of their having been created before copyright existed, or by their copyright term having expired. Some works are not covered by a country's copyright laws, and are therefore in the public domain; for example, in the United States, items excluded from copyright include the formulae of Newtonian physics and cooking recipes. Other works are actively dedicated by their authors to

4070-740: The public domain should be: "it should be a place of sanctuary for individual creative expression, a sanctuary conferring affirmative protection against the forces of private appropriation that threatened such expression". Patterson and Lindberg described the public domain not as a "territory", but rather as a concept: "[T]here are certain materials – the air we breathe, sunlight, rain, space, life, creations, thoughts, feelings, ideas, words, numbers – not subject to private ownership. The materials that compose our cultural heritage must be free for all living to use no less than matter necessary for biological survival." The term public domain may also be interchangeably used with other imprecise or undefined terms such as

4144-602: The public domain" can be traced to mid-19th-century France to describe the end of copyright term . The French poet Alfred de Vigny equated the expiration of copyright with a work falling "into the sink hole of public domain" and if the public domain receives any attention from intellectual property lawyers it is still treated as little more than that which is left when intellectual property rights, such as copyright , patents , and trademarks , expire or are abandoned. In this historical context Paul Torremans describes copyright as a, "little coral reef of private right jutting up from

4218-555: The public domain" is correct only for published works; unpublished works are under federal copyright for at least the life of the author plus 70 years. Legal traditions differ on whether a work in the public domain can have its copyright restored. In the European Union, the Copyright Duration Directive was applied retroactively, restoring and extending the terms of copyright on material previously in

4292-435: The public domain, derivative works such as adaptations in book and film may increase noticeably, as happened with Frances Hodgson Burnett 's novel The Secret Garden , which became public domain in the US in 1977 and most of the rest of the world in 1995. By 1999, the plays of Shakespeare, all public domain, had been used in more than 420 feature-length films. In addition to straightforward adaptation, they have been used as

4366-416: The public domain, e.g. civil law of continental Europe . This may even "effectively prohibit any attempt by copyright owners to surrender rights automatically conferred by law, particularly moral rights ". An alternative is for copyright holders to issue a license which irrevocably grants as many rights as possible to the general public. Real public domain makes licenses unnecessary, as no owner/author

4440-468: The public domain, to the extent that their expression in the form of software is not covered by copyright. Works created before the existence of copyright and patent laws also form part of the public domain. For example, the Bible and the inventions of Archimedes are in the public domain. However, translations or new formulations of these works may be copyrighted in themselves. Determination of whether

While the copyright has expired for the Peter Pan works by J. M. Barrie (the play Peter Pan, or the Boy Who Wouldn't Grow Up and the novel Peter and Wendy ) in the United Kingdom, it was granted a special exception under the Copyright, Designs and Patents Act 1988 (Schedule 6) that requires royalties to be paid for commercial performances, publications and broadcasts of

In the United States, the contents of patents are considered valid and enforceable for 20 years from the date of filing within the United States or 20 years from the earliest date of filing if under 35 USC 120, 121, or 365(c). However, the text and any illustration within a patent, provided the illustrations are essentially line drawings and do not in any substantive way reflect

4662-541: The public domain. Term extensions by the US and Australia generally have not removed works from the public domain, but rather delayed the addition of works to it. However, the United States moved away from that tradition with the Uruguay Round Agreements Act , which removed from the public domain many foreign-sourced works that had previously not been in copyright in the US for failure to comply with US-based formalities requirements . Consequently, in

4736-400: The public without regard for its intended use, it could become generic , and therefore part of the public domain. Because trademarks are registered with governments, some countries or trademark registries may recognize a mark, while others may have determined that it is generic and not allowable as a trademark in that registry. For example, the drug acetylsalicylic acid (2-acetoxybenzoic acid)

4810-518: The right holder cannot waive under applicable law, they are licensed in a way that mirrors as closely as possible the legal effect of a waiver. And finally, if there are any rights that the right holders cannot waive or license, they affirm that they will not exercise them and they will not assert any claim with respect to the use of the work, once again within the limits of applicable law. (...) In countries where moral rights exist but where they can be waived or not asserted, they are waived if asserted (e.g.

4884-499: The state or to an authors' association. The user does not have to seek permission to copy, present or perform the work, but does have to pay the fee. Typically the royalties are directed to support of living artists. In 2010, The Creative Commons proposed the Public Domain Mark (PDM) as symbol to indicate that a work is free of known copyright restrictions and therefore in the public domain. The public domain mark

4958-401: The story of Peter Pan within the UK, as long as Great Ormond Street Hospital (to whom Barrie gave the copyright) continues to exist. In a paying public domain regime, works that have entered the public domain after their copyright has expired, or traditional knowledge and traditional cultural expressions that have never been subject to copyright, are still subject to royalties payable to

5032-461: The term public domain and equates the public domain to public property and works in copyright to private property . However, the usage of the term public domain can be more granular, including for example uses of works in copyright permitted by copyright exceptions . Such a definition regards work in copyright as private property subject to fair use rights and limitation on ownership. A conceptual definition comes from Lange, who focused on what

5106-467: The works of Jane Austen , Lewis Carroll , Machado de Assis , Olavo Bilac and Edgar Allan Poe are in the public domain worldwide as they all died over 100 years ago. Project Gutenberg , the Internet Archive and Wikisource make tens of thousands of public domain books available online as ebooks . People have been creating music for millennia. The first musical notation system,

5180-411: The world may be excluded from copyright law and may therefore be considered to be in the public domain in their respective countries. They may also be in the public domain in other countries as well. The legal scholar Melville Nimmer has written that "it is axiomatic that material in the public domain is not protected by copyright, even when incorporated into a copyrighted work". Before 1 March 1989, in

For example, Hormel , producer of the canned meat product Spam , does not object to informal use of the word "spam" in reference to unsolicited commercial email. However, it has fought attempts by other companies to register names including the word 'spam' as a trademark in relation to computer products, despite that Hormel's trademark

5328-404: Was defined as things not yet appropriated. The term res communes was defined as "things that could be commonly enjoyed by mankind, such as air, sunlight and ocean." The term res publicae referred to things that were shared by all citizens, and the term res universitatis meant things that were owned by the municipalities of Rome. When looking at it from a historical perspective, one could say

5402-404: Was present in primitive tetrapods , the palatine bone is reduced in most living amphibians , forming, in frogs and salamanders , only a narrow bar between the vomer and maxilla. Early fossil reptiles retained the arrangement seen in more primitive vertebrates, but in mammals , the lower surface of the palatine became folded over during evolution, forming the horizontal plate, and meeting in

5476-428: Was widespread, in compliance with the law, but expansions of those laws intended to benefit literary works and responding to commercial music recording technology's reproducibility have led to stricter rules. Relatively recently, a normative view that copying in music is not desirable and lazy has become popular among professional musicians. US copyright laws distinguish between musical compositions and sound recordings,
