External Fixation An external fixator is a metal device that allows precise control of a bone. The fixator is composed or one or more metal bars and rings, which in turn connect to a child via metal pins and wires.By gradually manipulating the fixator on the outside, we can carefully control the position of the bones and joints on the inside.he fixator is composed or one or more metal bars and rings, which in turn connect to a child via metal pins and wires.

Heterophoria In contrast, fixation disparity is a very small deviation of the pointing directions of the eyes that is present while performing binocular fusion. Heterophoria is usually asymptomatic. This is when it is said to be compensated.

- Open reduction internal fixation is a method of surgically repairing a broken bone. First, to reposition the broken bones to restore their normal alignment. This is a procedure that is called 'fracture reduction.' Because the fracture is being surgically repositioned, this is considered an open reduction.

Tips about Fixation and Formalin The function of fixation is to inhibit the decay or autolysis of tissue so that samples may be preserved for future study. The quality of the fixation can greatly impact the usefulness of that tissue. Because tissue samples are valuable, several factors should be considered during the planning stages of an experiment.

What is ORIF Surgery? “Internal fixation” refers to the steel rods, screws, or plates used to keep the bone fracture stable in order to heal the right way and to help prevent infection. Open reduction internal fixation can also refer to the surgical repair of a joint, such as a hip or knee replacement. The surgical procedure is performed by a doctor who specializes in orthopedics, which is a branch of medicine concerning the musculoskeletal structure of the body.

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.n photosynthesis, energy from sunlight drives the carbon fixation pathway. Oxygenic photosynthesis is used by the primary producers —plants, algae, and cyanobacteria. They contain the pigment chlorophyll, and use the Calvin cycle to fix carbon autotrophically.

Hydrogenation Hydrogenation is a class of chemical reactions which result in an addition of hydrogen (H 2) usually to unsaturated organic compounds. The process constitutes the addition of hydrogen atoms to the double bonds of a molecule through the use of a catalyst. Hydrogen also adds to triple bonds if they are present.

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.

Nitrogen fixation Nitrogen fixation. Nitrogen fixation is the process by which nitrogen is taken from its stable gas form (N2) in air and changes into other nitrogen compounds (such as ammonia, nitrate and nitrogen dioxide) useful for other chemical processes. It is an important part of the nitrogen cycle. Nitrogen is fixed in biological and non-biological ways:

- Now, let's expand that knowledge of dilations in relation to 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. dilation is a transformation, DO,k, with center O and a scale factor of k that is not zero, that maps O to itself and any other point P to P' . The center O is a fixed point, P' is the image of P, points O, P and P' are collinear, and.
