COHERENS
COHERENS is an open-source hydrodynamic computer model for shallow waters. It was developed in the 1990s by the Royal Belgian Institute of Natural Sciences (RBINS). The name COHERENS is an acronym of COupled Hydrodynamical Ecological model for REgioNal Shelf seas. COHERENS can be used in 1D, 2D or 3D mode and can model both salt waters such as coastal and shelf seas and freshwater basins such as lakes. Applications of the model include obtaining a better understanding of shallow water systems and managing pollution.

Salakapurusa
According to the Jain cosmology, the śalākapuruṣa (Sanskrit: शलाकपुरूष) "illustrious or worthy persons" are 63 illustrious beings who appear during each half-time cycle. They are also known as the triṣaṣṭiśalākāpuruṣa (63 illustrious persons). The Jain universal or legendary history is a compilation of the deeds of these illustrious persons. Their life stories are said to be most inspiring. The śalākāpuruṣa comprise 24 Tirthankaras (Teaching Gods), twelve Chakravartin (universal monarchs, emperors of six continents), nine Balabhadras (gentle heroes), nine Narayanas (warrior heroes) and nine Prati-narayanas (anti-heroes). According to Jain cosmology, time is without beginning and eternal. The Kālacakra, the cosmic wheel of time, rotates ceaselessly. The wheel of time is divided into two half-rotations, Utsarpiṇī or ascending time cycle and Avasarpiṇī, the descending time cycle, occurring continuously after each other. Utsarpiṇī is a period of progressive prosperity and happiness where the time spans and ages are at an increasing scale while the Avasarpiṇī is a period of increasing sorrow and immorality with decline in time spans of the epochs. During each such time cycle, these 63 illustrious persons appear and establish the religion and order in society. According to Jain cosmology, since time is eternal, infinite kalacakras have elapsed and will occur in future and hence infinite sets of these 63 illustrious persons have appeared, and will appear, to establish order and religion in their respective eras.

French Republican Calendar
The French Republican calendar (French: calendrier républicain français), also commonly called the French Revolutionary calendar (calendrier révolutionnaire français), was a calendar created and implemented during the French Revolution , and used by the French government for about 12 years from late 1793 to 1805, and for 18 days by the Paris Commune in 1871. The revolutionary system was designed in part to remove all religious and royalist influences from the calendar, and was part of a larger attempt at decimalisation in France (which also included decimal time of day, decimalisation of currency, and metrication). It was used in government records in France and other areas under French rule, including Belgium, Luxembourg, and parts of the Netherlands, Germany, Switzerland, Malta, and Italy.

Cultural Eutrophication
Cultural eutrophication is when a flux of excess nutrients from human activity are added into a local run-off which in turns speeds up the natural eutrophication. This is caused by human activity. The problem became apparent once the green revolution and industrial revolution began in the last century. Phosphates and nitrates are the two main nutrients that cause cultural eutrophication as they enrich the water, allowing for aquatic plants such as algae to grow rapidly. Algae is prone to blooming into large quantities removing oxygen from the water generating anoxic conditions. This anoxic environment kills off any organisms in the water body and make it hard for terrestrial animals to gain access to the water for drinking. Increased competition for the added nutrients can cause potential disruption to entire ecosystems and food webs, as well as a loss of habitat and biodiversity of species. There are many ways in which nutrients are added through human activity, including, but not limited to: waste treatment plants, golf courses, fertilizing lawns, burning of fossil fuels and agricultural practices. Cultural eutrophication can occur in fresh water and salt water bodies, usually shallow waters are the most susceptible. In shallow lakes, sediments are frequently disturbed by wind-wave and resuspended, which result in huge nutrients release to overlying water As well the shallow areas are normally where the run-off reaches first and has less water to dilute the excess nutrients. This begins to cause many problems for the nearby wildlife as well as recreational activities for humans. Eutrophication restricts water use for fisheries, recreation, industry and drinking because of increased growth of undesirable algae and aquatic weeds and the oxygen shortages caused by their death and decomposition.

Marshall-Marchetti-Krantz
Urinary incontinence (UI), also known as involuntary urination, is any uncontrolled leakage of urine. It is a common and distressing problem, which may have a large impact on quality of life. It has been identified as an important issue in geriatric health care. The term enuresis is often used to refer to urinary incontinence primarily in children, such as nocturnal enuresis (bed wetting). UI is an example of a stigmatized medical condition, which creates barriers to successful management and makes the problem worse. People may be too embarrassed to seek medical help, and attempt to self-manage the symptom in secrecy from others. Pelvic surgery, pregnancy, childbirth, and menopause are major risk factors. Urinary incontinence is often a result of an underlying medical condition but is under-reported to medical practitioners. There are four main types of incontinence: Treatments include pelvic floor muscle training, bladder training, surgery, and electrical stimulation. Behavioral therapy generally works better than medication for stress and urge incontinence. The benefit of medications is small and long term safety is unclear. Urinary incontinence is more common in older women.

Ensembl Genomes
Ensembl Genomes is a scientific project to provide genome-scale data from non-vertebrate species. The project is run by the European Bioinformatics Institute, and was launched in 2009 using the Ensembl technology. The main objective of the Ensembl Genomes database is to complement the main Ensembl database by introducing five additional web pages to include genome data for bacteria, fungi, invertebrate metazoa, plants, and protists. For each of the domains, the Ensembl tools are available for manipulation, analysis and visualization of genome data. Most Ensembl Genomes data is stored in MySQL relational databases and can be accessed by the Ensembl Perl API, virtual machines or online. Ensembl Genomes is an open project, and most of the code, tools, and data are available to the public. Ensembl and Ensembl Genomes software uses a "permissive Apache-style open-source" license, making it free for all users.

Cognitive Neuroscience of Visual Object Recognition
Visual object recognition refers to the ability to identify the objects in view based on visual input. One important signature of visual object recognition is "object invariance", or the ability to identify objects across changes in the detailed context in which objects are viewed, including changes in illumination, object pose, and background context..
