Antigen/Antibody Tests for Infectious Disease Complement fixation refers to a reaction in which an antigen binds with an antibody, forming a combination that causes complement (a complex group of blood proteins) to become fixed at the same site. Detection of this complement fixation reaction leads to identification of the original antigen.

Carbon fixation Carbon fixation or сarbon assimilation refers to the conversion process of inorganic carbon (carbon dioxide) to organic compounds by living organisms.The most prominent example is photosynthesis, although chemosynthesis is another form of carbon fixation that can take place in the absence of sunlight.Organisms that grow by fixing carbon are called autotrophs.he most prominent example is photosynthesis, although chemosynthesis is another form of carbon fixation that can take place in the absence of sunlight.

Nitrogen fixation Nitrogen fixation is a process by which nitrogen in the Earth's atmosphere is converted into ammonia or other molecules available to living organisms. Atmospheric nitrogen or molecular dinitrogen is relatively inert: it does not easily react with other chemicals to form new compounds. The fixation process frees nitrogen atoms from their triply bonded diatomic form, N≡N, to be used in other ways. Nitrogen fixation is essential for some forms of life because inorganic nitrogen compounds are ...

In Journalism, what is a Fixer? A fixer is someone who offers assistance to foreign journalists who are trying to get a story. Fixers use their local experience and contacts to smooth the way for their employers, and many receive a high rate of pay, especially when compared to locally available wages.or example, when a fixer says that a location is too unsafe to visit, a journalist may seek another way to get the story, in contrast with the past, when journalists would have insisted upon making the trip anyway.

- Lesson Summary. Carbon fixation is the process by which inorganic carbon is added to an organic molecule. Carbon fixation occurs during the light independent reaction of photosynthesis and is the first step in the C3 or Calvin Cycle.n this lesson you will discover what carbon fixation means, when it occurs and what enzyme is involved. The lesson will discuss where the process of carbon fixation falls in photosynthesis as well as give a brief idea of a process by which carbon can be freed from fixation.

- (a + b) + c = a + (b + c) In programming languages, the associativity (or fixity) of an operator is a property that determines how operators of the same precedence are grouped in the absence of parentheses; i.e. in what order each operator is evaluated. This can differ between programming languages. In CPU caches, associativity is a method of optimizing performance.

- Fixation is the conversion of gaseous nitrogen to ammonia or nitrate. The most common kind of fixation is biological fixation which is carried out by a variety of organisms, including blue-green algae, the soil bacteria Azobacter, and the association of legume plants and the bacteria Rhizobium. Additionally, nitrogen can be fixed by some inorganic processes.

Fixation (population genetics) Fixation can refer to a gene in general or particular nucleotide position in the DNA chain (locus). In the process of substitution, a previously non-existent allele arises by mutation and undergoes fixation by spreading through the population by random genetic drift and/or positive selection.

Nitrogen fixation Nitrogen fixation is a process by which nitrogen in the Earth's atmosphere is converted into ammonia (NH 3) or other molecules available to living organisms. Atmospheric nitrogen or molecular dinitrogen (N 2) is relatively inert: it does not easily react with other chemicals to form new compounds.

Fixation (psychology) In Three Essays on the Theory of Sexuality (1905), Freud distinguished the fixations of the libido on an incestuous object, from a fixation upon a specific, partial aim, such as voyeurism.sychoanalytic therapy involved producing a new transference fixation in place of the old one. The new fixation-for example a father-transference onto the analyst-may be very different from the old, but will absorb its energies and enable them eventually to be released for non-fixated purposes.

- dilation is a transformation (notation) that produces an image that is the same shape as the original, but is a different size. A dilation stretches or shrinks the original figure. The description of a dilation includes the scale factor (or ratio) and the center of the dilation.The center of dilation is a fixed point in the plane about which all points are expanded or contracted. It is the only invariant point under a dilation.A dilation of scalar factor k whose center of dilation is the origin may be written: Dk (x, y) = (kx, ky). If the scale factor, k, is greater than 1, the image is an enlargement (a stretch). If the scale factor is between 0 and 1, the image is a reduction (a shrink). dilation of scalar factor k whose center of dilation is the origin may be written: Dk (x, y) = (kx, ky). If the scale factor, k, is greater than 1, the image is an enlargement (a stretch).

Geometry A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. The description of a dilation includes the scale factor (constant of dilation) and the center of the dilation. The center of a dilation is a fixed point in the plane about which all points are expanded or contracted.

Nitrogen fixation Previous (Nitrogen dioxide). Next (Nitroglycerin). Nitrogen fixation is the process by which nitrogen is taken from its relatively inert molecular form (N 2) in the atmosphere and converted into nitrogen compounds useful for other chemical processes (such as, notably, ammonia, nitrate, and nitrogen dioxide).iological Nitrogen Fixation (BNF) occurs when atmospheric nitrogen is converted to ammonia by a bacterial enzyme called nitrogenase. Microorganisms that fix nitrogen are called diazotrophs.

- Proper care of a broken bone should relieve pain and help the bone heal correctly. Your doctor has decided that external fixation is the best treatment for you. External fixation is a device worn outside the body. This device, which is also called a fixator, is connected to the bone with bone screws or pins.The pins pass through the skin and sometimes the muscles, to connect the external fixator to the bone. Two or more pins are placed on either side of the break in the bone.roper care of a broken bone should relieve pain and help the bone heal correctly.

What is JOINT FIXATION? A Quick Definition Physical stress (falls, accidents, sports injuries, repetitive use), emotional stress (job worries, family tension, fighting), and chemical stress (medications, cigarettes, environmental toxins) cause the body to shift out of balance. Once the body is subjected to these stressors, subluxation may occur.ut what’s harder to understand is that once adhesions come into the picture, any two vertebrae that make up one joint can get “glued together” and not have available their normal movement. This condition is called joint fixation.
