 Synthetic biological membrane with self organizing properties - US Patent 6537575
phase changes) that are compatible to the biological material or to the target for the biological material.
Given the colloidal nature of such membranes, wherein polar groups extend outwardly in physiologic situations, the encapsulation of proteins, organic molecules, aqueous molecules, metals and colloidal metals (such as semiconductor colloids) is facilitated with the invented material.
The material is formed by the noncovalent self-assembly of a quaternary mixture of a phospholipid, a lipopolymer, or diblock or triblock co-polymer or polymer-grafted amphiphile, and a surfactant dispersed in water.

 Patentstyret - Patents Act
Biological material, which is isolated from its natural environment or produced by means of a technical process, may be the subject of an invention even if it previously occurred in nature.
If an invention concerns or uses biological material from the human body, the patent application shall include information on whether the person from whom the material has been derived has given his/her consent to the use of the biological material, in accordance with the law of 21st February 2003 no 12 about bio banks.
An essentially biological process means, for the purpose of this legal text, a process, which consists entirely of natural phenomena such as crossing or selection.

 Biological pump - Wikipedia, the free encyclopedia
As these processes are generally slower than synthesis processes, and because the particulate material is sinking, the biological pump transports material from the surface of the ocean to its depths.
In oceanic biogeochemistry, the biological pump is the sum of a suite of biologically-mediated processes that transport carbon from the surface euphotic zone to the ocean's interior.
The biological pump has a physico-chemical counterpart known as the solubility pump.

 SwRI Fall 1998 Technology Today Article
In this application, man-made materials could be designed to mimic their biological counterparts so that they provide not only an attractive biological and biochemical environment, but, for structural tissues such as bone and cartilage, also provide the correct mechanical environment for viable tissue to grow.
At the nano-scale (one billionth of a meter) level, bone tissue is a composite material comprised of an organic phase, consisting mainly of the protein-based material collagen, and a mineral phase, consisting primarily of hydroxyapatite.
Imagine a material with the ability to sense varying loads, adapt its architecture to maintain a constant reliability level in response to those loads, repair any damage occurring as a result of everyday use, and survive tens of millions of load cycles without failure.

It is caused by neurobiological processes and is as much part of the natural biological order as any other biological features such as photosynthesis, digestion, or mitosis.I don't see how Searle can maintain that his view is some type of material monism (he strongly opposes being called a property dualist).
If the properties of the irreducible, first-person experience of consciousness are able to fit in his materialist/scientist ontology, it seems that this allows for the exact same properties one would essentially predicate of ghosts, ghouls, and God.
If these properties are supposed to be consistent with materialism, then Searle seems to be espousing a strange sort of materialism.

 Determinism - Wikipedia, the free encyclopedia
One approach to determinism is to argue that materialism does not present a correct understanding of the universe, not because it is wrong in its general picture of the determinate interactions that occur among material things, but because it ignores the souls of human beings.
Determinism is associated with, and relies upon, the ideas of Materialism and Causality.
Determinism in the West is often associated with Newtonian physics, which depicts the physical matter of the universe as operating according to a set of fixed, knowable laws.

 Encyclopedia: Biological types
Ensuring that biological types are kept in good condition and made available for examination by taxonomists are two important functions of such collections.
The various types described above are needed because many species description go back one or two centuries and type designation was not always done, types were not always well kept or preserved, or intervening events have resulted in destruction of original type material.
Included in the type description would be a discussion of similarities to and differences from closely related species and where a type specimen or specimens were sent for curation.
