Promession
Promession is an idea of how to dispose human remains by way of freeze drying. The concept of promession was developed by Swedish biologist Susanne Wiigh-Mäsak, who derived the name from the Italian word for "promise" (''promessa''). She founded Promessa Organic AB in 1997 to commercially pursue her idea. The company went bankrupt in 2015 without being able to produce a functioning facility. The idea of promession is questioned and not a functional method according to critics. Process The idea of promession involves five steps: # Coffin separation: the body is placed into the chamber # Cryogenic freezing: liquid nitrogen at −196 °C crystallizes the body # Vibration: the body is disintegrated into particles within minutes # Freeze drying: particles are freeze dried in a drying chamber, leaving approximately 30% of the original weight # Metal separation: any metals (e.g., tooth amalgam, artificial hips, etc.) are removed, either by magnetism or by sieving.

Natural Burial
Natural burial is the interment of the body of a dead person in the soil in a manner that does not inhibit decomposition but allows the body to be naturally recycled. It is an alternative to other contemporary Western burial methods and funerary customs. The body may be prepared without chemical preservatives or disinfectants such as embalming fluid, which might destroy the microbial decomposers that break the body down. It may be buried in a biodegradable coffin, casket, or shroud. The grave does not use a burial vault or outer burial container that would prevent the body's contact with soil. The grave should be shallow enough to allow microbial activity similar to that found in composting. Natural burials can take place both on private land (subject to regulations) and in any cemetery that will accommodate the vault-free technique. While all natural burials seek to prevent environmental damage done by conventional techniques, some go a step further by using burial fees to a ...

Alkaline Hydrolysis (death Custom)
Alkaline hydrolysis (also called biocremation, resomation, flameless cremation, aquamation or water cremation) is a process for the disposal of human and pet remains using lye and heat, and is an alternative to burial or cremation. Process The process is based on alkaline hydrolysis: the body is placed in a pressure vessel that is then filled with a mixture of water and potassium hydroxide, and heated to a temperature around , but at an elevated pressure, which prevents boiling. Instead, the body is effectively broken down into its chemical components, which takes approximately four to six hours. A lower temperature and pressure may be used, but at a longer duration (, 14 to 16 hours). At the beginning of the process, the mixture is fairly basic, with a pH level of approximately 14; pH drops to 11 by the end, but the final pH level depends on the total operation time and the amount of fat in the body. The result is a quantity of green-brown tinted liquid (containing amino a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Disposal Of Human Corpses
Disposal of human corpses, also called final disposition, is the practice and process of dealing with the remains of a deceased human being. Disposal methods may need to account for the fact that soft tissue will decompose relatively rapidly, while the skeleton will remain intact for thousands of years under certain conditions. Several methods for disposal are practiced. A funeral is a ceremony that may accompany the final disposition. Regardless, the manner of disposal is often dominated by spirituality with a desire to hold vigil for the dead and may be highly ritualized. In cases of mass death, such as war and natural disaster, or in which the means of disposal are limited, practical concerns may be of greater priority. Ancient methods of disposing of dead bodies include cremation practiced by the Romans, Greeks, Hindus, and some Mayans; burial practiced by the Chinese, Japanese, Bali, Jews, Christians, and Muslims, as well as some Mayans; mummification, a type of ...

Casket
A casket jewelry box is a container that is usually smaller than a chest, and in the past were typically decorated. Whereas cremation jewelry is a small container, usually in the shape of a pendant or bracelet, to hold a small amount of ashes. History In recent times they are mostly receptacles for trinkets and jewels, but in earlier periods, when other types of container were rarer, and the amount of documents held by the typical person far fewer, they were used for keeping important documents and many other purposes. It may take a very modest form, covered in leather and lined with satin, or it may reach the monumental proportions of the jewel cabinets which were made for Marie Antoinette, one of which is at Windsor, and another at Versailles. Both were the work of Schwerdfeger as cabinet maker, his assistants Michael Reyad, Mitchell Stevens, Christopher Visvis, Degault as miniature painter, and Thomire as chaser. Caskets are often made in precious materials, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biodegradable Waste Management
Biodegradation is the breakdown of organic matter by microorganisms, such as bacteria and fungi. It is generally assumed to be a natural process, which differentiates it from composting. Composting is a human-driven process in which biodegradation occurs under a specific set of circumstances. The process of biodegradation is threefold: first an object undergoes biodeterioration, which is the mechanical weakening of its structure; then follows biofragmentation, which is the breakdown of materials by microorganisms; and finally assimilation, which is the incorporation of the old material into new cells. In practice, almost all chemical compounds and materials are subject to biodegradation, the key element being time. Things like vegetables may degrade within days, while glass and some plastics take many millennia to decompose. A standard for biodegradability used by the European Union is that greater than 90% of the original material must be converted into , water and minerals by ...

Death Customs
This article is about death in the different cultures around the world as well as ethical issues relating to death, such as martyrdom, suicide and euthanasia. Death refers to the permanent termination of life-sustaining processes in an organism, i.e. when all biological systems of a human being cease to operate. Death and its spiritual ramifications are debated in every manner all over the world. Most civilizations dispose of their dead with rituals developed through spiritual traditions. Disposal of remains In most cultures, after the last offices have been performed and before the onset of significant decay, relations or friends arrange for ritual disposition of the body, either by destruction, or by preservation, or in a secondary use. In the US, this frequently means either cremation or interment in a tomb. There are various methods of destroying human remains, depending on religious or spiritual beliefs, and upon practical necessity. Cremation is a very old and quite comm ...

Humus
In classical soil science, humus is the dark organic matter in soil that is formed by the decomposition of plant and animal matter. It is a kind of soil organic matter. It is rich in nutrients and retains moisture in the soil. Humus is the Latin word for "earth" or "ground". In agriculture, "humus" sometimes also is used to describe mature or natural compost extracted from a woodland or other spontaneous source for use as a soil conditioner. It is also used to describe a topsoil horizon that contains organic matter (''humus type'', ''humus form'', or ''humus profile''). Humus has many nutrients that improve the health of soil, nitrogen being the most important. The ratio of carbon to nitrogen (C:N) of humus commonly ranges between eight and fifteen with the median being about twelve. It also significantly affects the bulk density of soil. Humus is amorphous and lacks the "cellular cake structure characteristic of plants, micro-organisms or animals". Description The prim ...

Soil Horizon
A soil horizon is a layer parallel to the soil surface whose physical, chemical and biological characteristics differ from the layers above and beneath. Horizons are defined in many cases by obvious physical features, mainly colour and texture. These may be described both in absolute terms (particle size distribution for texture, for instance) and in terms relative to the surrounding material, i.e. 'coarser' or 'sandier' than the horizons above and below. The identified horizons are indicated with symbols, which are mostly used in a hierarchical way. Master horizons (main horizons) are indicated by capital letters. Suffixes, in form of lowercase letters and figures, further differentiate the master horizons. There are many different systems of horizon symbols in the world. No one system is more correct—as artificial constructs, their utility lies in their ability to accurately describe local conditions in a consistent manner. Due to the different definitions of the horizon symb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Freeze Drying
Freeze drying, also known as lyophilization or cryodesiccation, is a low temperature Food drying, dehydration process that involves freezing the product and lowering pressure, removing the ice by Sublimation (phase transition), sublimation. This is in contrast to dehydration by most conventional methods that evaporate water using heat. Because of the low temperature used in processing, the rehydrated product retains much of its original qualities. When solid objects like strawberries are freeze dried the original shape of the product is maintained. If the product to be dried is a liquid, as often seen in pharmaceutical applications, the properties of the final product are optimized by the combination of excipients (i.e., inactive ingredients). Primary applications of freeze drying include biological (e.g., bacteria and yeasts), biomedical (e.g., surgical transplants), food processing (e.g., coffee) and Food preservation, preservation.

Hip Replacement
Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi (half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures. A total hip replacement (total hip arthroplasty or THA) consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is one of the most common orthopaedic operations, though patient satisfaction varies widely. Approximately 58% of total hip replacements are estimated to last 25 years. The average cost of a total hip replacement in 2012 was $40,364 in the United States, and about $7,700 to $12,000 in most European countries. Medical uses Total hip replacement is most commonly used to treat joint failure caused by osteoarthritis. Other indications include rheumatoi ...

Amalgam (dentistry)
Dental amalgam is a liquid mercury and metal alloy mixture used in dentistry to fill cavities caused by tooth decay. Low-copper amalgam commonly consists of mercury (50%), silver (~22–32%), tin (~14%), zinc (~8%) and other trace metals. Dental amalgams were first documented in a Tang Dynasty medical text written by Su Gong (苏恭) in 659, and appeared in Germany in 1528. In the 1800s, amalgam became the dental restorative material of choice due to its low cost, ease of application, strength, and durability. In July 2018 the EU prohibited amalgam for dental treatment of children under 15 years and of pregnant or breastfeeding women. History of use There are, according to Geir Bjørklund, indications that dental amalgam was used in the first part of the Tang Dynasty in China (AD 618–907), and in Germany by Strockerus in about 1528. Evidence of a dental amalgam first appears in the Tang Dynasty medical text ''Xinxiu bencao''《新修本草》 written by Su Gong (苏恭) i ...
