Ampoule Thècle 01
An ampoule (also ampul and ampule) is a small sealed vial which is used to contain and preserve a sample, usually a solid or liquid. Ampoules are usually made of glass. Modern ampoules are most commonly used to contain pharmaceuticals and chemicals that must be protected from air and contaminants. They are hermetically sealed by melting the thin top with an open flame, and usually opened by snapping off the neck. The space above the chemical may be filled with an inert gas before sealing. The walls of glass ampoules are usually sufficiently strong to be brought into a glovebox without any difficulty. Glass ampoules are more expensive than bottles and other simple containers, but there are many situations where their superior imperviousness to gases and liquids and all-glass interior surface are worth the extra cost. Examples of chemicals sold in ampoules are injectable pharmaceuticals, air-sensitive reagents like tetrakis(triphenylphosphine)palladium(0), hygroscopic materials ...

Passivation (chemistry)
Passivation, in physical chemistry and engineering, refers to coating a material so it becomes "passive", that is, less readily affected or corroded by the environment. Passivation involves creation of an outer layer of shield material that is applied as a microcoating, created by chemical reaction with the base material, or allowed to build by spontaneous oxidation in the air. As a technique, passivation is the use of a light coat of a protective material, such as metal oxide, to create a shield against corrosion. Passivation of silicon is used during fabrication of microelectronic devices. In electrochemical treatment of water, passivation reduces the effectiveness of the treatment by increasing the circuit resistance, and active measures are typically used to overcome this effect, the most common being polarity reversal, which results in limited rejection of the fouling layer. When exposed to air, many metals naturally form a hard, relatively inert surface layer, usually an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anointing
Anointing is the ritual act of pouring aromatic oil over a person's head or entire body. By extension, the term is also applied to related acts of sprinkling, dousing, or smearing a person or object with any perfumed oil, milk, butter, or other fat. Scented oils are used as perfumes and sharing them is an act of hospitality. Their use to introduce a divine influence or presence is recorded from the earliest times; anointing was thus used as a form of medicine, thought to rid persons and things of dangerous spirits and demons which were believed to cause disease. In present usage, "anointing" is typically used for ceremonial blessings such as the coronation of European monarchs. This continues an earlier Hebrew practice most famously observed in the anointings of Aaron as high priest and both Saul and David by the prophet Samuel. The concept is important to the figure of the Messiah or the Christ (Hebrew and Greek for "The Anointed One") who appear prominently in Jewish a ...

Holy Ampulla
The Holy Ampulla or Holy Ampoule (''Sainte Ampoule'' in French) was a glass vial which, from its first recorded use by Pope Innocent II for the anointing of Louis VII in 1131 to the coronation of Louis XVI in 1774, held the chrism or anointing oil for the coronation of the kings of France. History The role played by the ''Sainte Ampoule'' in the ''sacre'' of the kings of France is specified in a document of ca 1260, recently republished and examined in detail. Legend of the Baptism of the Moribund Pagan There was an early legend associated with St Remigius known as the ''Legend of the Baptism of the Moribund Pagan'', according to which a dying pagan asked for baptism at the hands of St Remigius (Remi), but when it was found that there was no Oil of the Catechumens or sacred Chrism available for the proper administration of the baptismal ceremony, St Remigius ordered two empty vials be placed on an altar and as he prayed before them these two vials miraculously filled respectiv ...

Naples
Naples (; it, Napoli ; nap, Napule ), from grc, Νεάπολις, Neápolis, lit=new city. is the regional capital of Campania and the third-largest city of Italy, after Rome and Milan, with a population of 909,048 within the city's administrative limits as of 2022. Its province-level municipality is the third-most populous metropolitan city in Italy with a population of 3,115,320 residents, and its metropolitan area stretches beyond the boundaries of the city wall for approximately 20 miles. Founded by Greeks in the first millennium BC, Naples is one of the oldest continuously inhabited urban areas in the world. In the eighth century BC, a colony known as Parthenope ( grc, Παρθενόπη) was established on the Pizzofalcone hill. In the sixth century BC, it was refounded as Neápolis. The city was an important part of Magna Graecia, played a major role in the merging of Greek and Roman society, and was a significant cultural centre under the Romans. Naples served a ...

Naples Cathedral
The Naples Cathedral ( it, Duomo di Napoli; nap, Viscuvato 'e Napule), or Cathedral of the Assumption of Mary ( it, Cattedrale di Santa Maria Assunta, links=no), is a Roman Catholic cathedral, the main church of Naples, southern Italy, and the seat of the Archbishop of Naples. It is widely known as the ''Cattedrale di San Gennaro'' (Cathedral of Saint Januarius), in honour of the city's patron saint. History The present cathedral in Angevin gothic style ( it, gotico angioino) was commissioned by King Charles I of Anjou. Construction continued during the reign of his successor, Charles II (1285–1309) and was completed in the early 14th century under Robert of Anjou. It was built on the foundations of two palaeo-Christian basilicas, whose traces can still be clearly seen. Underneath the building excavations have revealed Greek and Roman artifacts. The Archbishop's Palace adjoins the cathedral. Interior and artwork The cathedral gives access to the archaeological remains ...

Benevento
Benevento (, , ; la, Beneventum) is a city and ''comune'' of Campania, Italy, capital of the province of Benevento, northeast of Naples. It is situated on a hill above sea level at the confluence of the Calore Irpino (or Beneventano) and the Sabato. In 2020, Benevento has 58,418 inhabitants. It is also the seat of a Catholic archbishop. Benevento occupies the site of the ancient Beneventum, originally Maleventum or even earlier Maloenton. The meaning of the name of the town is evidenced by its former Latin name, translating as good or fair wind. In the imperial period it was supposed to have been founded by Diomedes after the Trojan War. Due to its artistic and cultural significance, the Santa Sofia Church in Benevento was declared a UNESCO World Heritage Site in 2011, as part of a group of seven historic buildings inscribed as Longobards in Italy, Places of Power (568–774 A.D.).

Saint Januarius
Januarius ( ; la, Ianuarius; Neapolitan language, Neapolitan and it, Gennaro), also known as , was Roman Catholic Archdiocese of Benevento, Bishop of Benevento and is a Christian martyrs, martyr and saint of the Catholic Church and the Eastern Orthodox Church. While no contemporary sources on his life are preserved, later sources and Christian legend, legends claim that he died during the Great Persecution, which ended with Diocletian's retirement in 305. Januarius is the patron saint of Naples, where the faithful gather three times a year in Naples Cathedral to witness the liquefaction of what is claimed to be a sample of his blood kept in a sealed glass ampoule. Life Little is known of the life of Januarius, and what follows is mostly derived from later Christian sources, such as the ''Acta Bononensia'' (BHL 4132, not earlier than 6th century) and the ''Acta Vaticana'' (BHL 4115, 9th century), and from later folk traditions.

Blood
Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells. Blood in the circulatory system is also known as ''peripheral blood'', and the blood cells it carries, ''peripheral blood cells''. Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). The most abundant cells in vertebrate blo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martyr
A martyr (, ''mártys'', "witness", or , ''marturia'', stem , ''martyr-'') is someone who suffers persecution and death for advocating, renouncing, or refusing to renounce or advocate, a religious belief or other cause as demanded by an external party. In the martyrdom narrative of the remembering community, this refusal to comply with the presented demands results in the punishment or execution of an actor by an alleged oppressor. Accordingly, the status of the 'martyr' can be considered a posthumous title as a reward for those who are considered worthy of the concept of martyrdom by the living, regardless of any attempts by the deceased to control how they will be remembered in advance. Insofar, the martyr is a relational figure of a society's boundary work that is produced by collective memory. Originally applied only to those who suffered for their religious beliefs, the term has come to be used in connection with people killed for a political cause. Most martyrs are consid ...

Catacombs Of Rome
The Catacombs of Rome ( it, Catacombe di Roma) are ancient catacombs, underground burial places in and around Rome, of which there are at least forty, some rediscovered only in recent decades. Though most famous for Christian burials, either in separate catacombs or mixed together, Jews and also adherents of a variety of pagan Roman religions were buried in catacombs, beginning in the 2nd century AD,Toynbee: 39–40. occasioned by the ancient Roman ban on burials within a city, and also as a response to overcrowding and shortage of land. The most extensive and perhaps the best known is the Christian Catacomb of Callixtus located near the Park of the Caffarella, but there are other sites, both Christian and not, scattered around the city, some of which are now engulfed by modern urban sprawl. The Christian catacombs are extremely important for the history of Early Christian art, as they contain the great majority of examples from before about 400 AD, in fresco and sculpture, as ...
