- The [4Fe–4S] cluster is ubiquitous to a class of base excision repair enzymes in organisms ranging from bacteria to man and was first considered as a structural element, owing to its redox stability under physiological conditions.

four-factor authentication (4FA) Four-factor authentication is a newer security paradigm than two-factor or three-factor authentication. Four factor systems are sometimes used in businesses and government agencies that require extremely high security. Knowledge factors include all things a user must know in order to log in, such as a user name and password or personal identification number (PIN). 2  Possession factors include anything a user must have in their possession to log in, such as a one-time password token (OTP token) or a smartphone with an OTP app.

Computer cluster The first production system designed as a cluster was the Burroughs B5700 in the mid-1960s. This allowed up to four computers, each with either one or two processors, to be tightly coupled to a common disk storage subsystem in order to distribute the workload.hen a node in a cluster fails, strategies such as  fencing  may be employed to keep the rest of the system operational. Fencing is the process of isolating a node or protecting shared resources when a node appears to be malfunctioning.

Does your FD use ICS/NIMS? • The incident is typically contained within an hour or two after resources arrive on scene Type 4 incidents would typically include a major structure fire, a multiple vehicle crash with multiple patients, or a small hazmat spill. • Command and General Staff functions are activated only if needed • Several resources are required to mitigate the incident, possibly including Task Forces or Strike Teams • The incident is typically contained within one operation period in the control phase, usually within a few hours after resources arrive on scene

- Due to the limitations of today’s measuring devices, there is a maximum level to which we can zoom out. At that level, we see a universe made up of mainly two components. There are the threadlike structures known as filaments that are made up of isolated galaxies, groups, clusters and superclusters.And then there are vast empty bubbles of empty space called voids. You can read more about structure of the universe here in Universe Today.ue to the limitations of today’s measuring devices, there is a maximum level to which we can zoom out.

Laser Classification Explanation These lasers are Class 1M or 2M under the current Classification system. Class 3R. Radiation in this class is considered low risk, but potentially hazardous. The class limit for 3R is 5x the applicable class limit for Class 1 (for invisible radiation) or class 2 (for visible radiation).

Cluster analysis Cluster analysis or clustering is the task of grouping a set of objects in such a way that objects in the same group (called a cluster) are more similar (in some sense or another) to each other than to those in other groups (clusters). Subspace models: in Biclustering (also known as Co-clustering or two-mode-clustering), clusters are modeled with both cluster members and relevant attributes. 2  Group models: some algorithms do not provide a refined model for their results and just provide the grouping information.

- ECN 212 Four Firm Concentration Ratio. 25 points. The four firm concentration ratio is the percentage of the value of total sales accounted for by the four largest firms in an industry. In more general terms, it is the market share of the four largest firms in an industry. From a market structure standpoint, if the four firm concentration ratio is greater than 60% the market is an oligopoly. If it is less than 40% it is monopolistic competition. Often times we use things other than revenue to determine market share.

Tone cluster For instance, three adjacent piano keys (such as C, C ♯ , and D) struck simultaneously produce a tone cluster. Variants of the tone cluster include chords comprising adjacent tones separated diatonically, pentatonically, or microtonally.

Use of boudinaged rigid objects as a strain gauge: Insights from analogue and numerical models The mylonites contain boudinaged feldspar pophyroclasts in a plastically deformed quartz-rich matrix. We estimated extensional strains from boudinaged feldspar grains, and compared it with that obtained from the flattened shapes of recrystallized quartz grains. Boudinaged porphyroclasts always show a difference between boudinage strain and the actual bulk extension, as observed in physical experiments. The departure factor estimated for nearly symmetrical boudins is 0.74 when the object and the boudin aspect ratios are 1.28 and 0.66 respectively (Fig. 16a).

How C-4 Works C-4, or composition 4, is one variety of plastic explosive. The basic idea of plastic explosives, also called plastic bonded explosives (PBX), is to combine explosive chemicals with a plastic binder material. It coats the explosive material, so it's less sensitive to shock and heat.

Cluster Flies Cluster flies are capable of crawling through small openings in the walls of a structure. They hibernate in secluded parts of houses like attics and wall voids. On sunny winter days, the wall voids become warm and the cluster flies try to move toward light. Very often they find themselves in the inhabited parts of the house and the move to the windows. They cluster around the windows and they leave stains on walls and curtains if crushed. The cluster fly life cycle begins when a female lays her eggs in the soil in late summer or early fall.

- CF4 has four pairs of shared electrons between the central carbon  atom and the surrounding fluorine atoms. Because they are shared,  the bond is covalent. 1 person found this useful. Edit. …  Each florine is more electrongative than the carbon and tend to  attract electrons more than the carbom giving the florines a  negative charge. In most situations this would lead to the molecule  being polar but remember! The florines are opposite of eachother.

DNA repair glycosylases with a [4Feâ4S] cluster: A redox cofactor for DNA-mediated charge transport? Since it appeared that stable oxidation of the [4Fe–4S] cluster was not possible, nor was reduction feasible in a biological environment, the cofactor was relegated to a structural role. The [4Fe–4S] cluster was analogously assigned a structural role in MutY.
