It is all too exhausting: the unending requests to perform the role of rising Black artist; the pressure to deliver career-defining work seemingly every other month; the urgency to figure out how to get yourself and others free; the desperation to move beyond the city's histories and its continuing containments.

Passive ECCS The Automatic Depressurization System (ADS) consists of a series of valves which open to vent steam several feet under the surface of a large pool of liquid water (known as the wetwell or torus) in pressure suppression type containments (typically used in boiling water reactor designs), or directly into the primary containment structure in other types of containments, such as large-dry or ice-condenser containments (typically used in pressurized water reactor designs). The actuation of these valves depressurizes the reactor vessel and allows lower pressure coolant injection systems to function, which have very large capacities in comparison to the high pressure systems. Some depressurization systems are automatic in function, while others may require operators to manually activate them. In pressurized water reactors with large dry or ice condenser containments, the valves of the system are called Pilot operated release valves.

Vessel dished ends are mostly used in storage or pressure vessels in industry. These ends, which in upright vessels are the bottom and the top, use less space than a hemisphere (which is the ideal form for pressure containments) while requiring only a slightly thicker wall.

Early, late and open bisimilarity are distinct. The containments are proper, so \sim_o \subsetneq \sim_l \subsetneq \sim_e. In certain subcalculi such as the asynchronous pi-calculus, late, early and open bisimilarity are known to coincide. However, in this setting a more appropriate notion is that of asynchronous bisimilarity.

The comparator circuit evaluation problem can be solved in polynomial time, and so CC is contained in P ("circuit universality"). On the other hand, comparator circuits can solve directed reachability, and so CC contains NL. There is a relativized world in which CC and NC are incomparable, and so both containments are strict.

It is related to important classical complexity classes by the hierarchy P\subseteq BPP\subseteq BQP\subseteq PSPACE. Whether any of these containments is proper is still an open question. The difficulty of proving what cannot be done with classical computing is a common problem in definitively demonstrating quantum supremacy. Contrary to decision problems that require yes or no answers, sampling problems ask for samples from probability distributions.

Loose radioactive particles can be found throughout a radiological work facility. Barriers made of flexible materials help to confine the spread of this contamination and to protect workers from exposure. Barriers can be in the form of different configurations such as, sleeving, glovebags, containment tents, catch containments, bags, covers and protective clothing. Sleeving provided on rolls is often cut to length and used to cover radioactive material to prevent the spread of contamination during handling.

Differences in column shortenings are of particular concern for very tall buildings. In slender structures, creep may cause collapse due to long-time instability. The creep effects are particularly important for prestressed concrete structures (because of their slenderness and high flexibility), and are paramount in safety analysis of nuclear reactor containments and vessels. At high temperature exposure, as in fire or postulated nuclear reactor accidents, creep is very large and plays a major role.

Lead loaded gloves are often used in conjunction with tongs as they offer better dexterity and can be used in low radiation environments (such as hot cells used in hospital nuclear medicine labs). Some companies have developed tungsten loaded gloves which offer greater dexterity than lead loaded gloves, with better shielding than their counterparts. Gloves must be regularly replaced as the chemicals used for the cleaning/sterilisation process of the containments cause considerable wear and tear.

ZPP, co-RP, BPP, BQP, PP), which generalise P within PSPACE. It is unknown if any of these containments are strict. The definition of RP says that a YES answer is always right and that a NO answer might be wrong (because a question with the YES answer can be sometimes answered NO). In other words, while NO questions are always answered NO, you cannot trust the NO answer, it may be a mistaken answer to a YES question.

If the outward pressure from steam in a limiting accident is the dominant force, containments tend towards a spherical design, whereas if weight of the structure is the dominant force, designs tend towards a can design. Modern designs tend towards a combination. Containment systems for nuclear power reactors are distinguished by size, shape, materials used, and suppression systems. The kind of containment used is determined by the type of reactor, generation of the reactor, and the specific plant needs.

In 1969 Weinfled exhibited her early paintings in a one-woman show in Mabat Gallery in Tel-Aviv (Israel). The paintings explored containments of biomorphic shapes (such as flesh) within geometric boundaries. The exhibition was met with disdain by most of the local art critics. Over the next three years Weinfeld experimented with other juxtapositions of stylistic contrasts. Those were exhibited in numerous group shows, and eventually in 1972 in a one- woman show at the Bar-Kochba Gallery in Tel-Aviv.

Suppression systems are critical to safety analysis and greatly affect the size of containment. Suppression refers to condensing the steam after a major break has released it from the cooling system. Because decay heat does not go away quickly, there must be some long term method of suppression, but this may simply be heat exchange with the ambient air on the surface of containment. There are several common designs, but for safety-analysis purposes containments are categorized as either "large-dry", "sub-atmospheric", or "ice-condenser".

Evidently C_x \subseteq QC_x for all x in X. Overall we have the following containments among path components, components and quasicomponents at x: :PC_x \subseteq C_x \subseteq QC_x. If X is locally connected, then, as above, C_x is a clopen set containing x, so QC_x \subseteq C_x and thus QC_x = C_x. Since local path connectedness implies local connectedness, it follows that at all points x of a locally path connected space we have :PC_x = C_x = QC_x. Another class of spaces for which the quasicomponents agree with the components is the class of compact Hausdorff spaces.

The U-shaped pressure tubes containing the fuel were thermally isolated from the hot fuel assembly by two circular thermal baffle tubes around the fuel assembly. This allowed the pressure tubes to operate at low temperatures, essentially that of the moderator tank which was maintained about 155 degrees F and close to atmospheric pressure. The moderator tank contained heavy water which moderated the fission process during operation of the reactor. The CVTR containment design was a new concept at the time; the general design later became the prevalent design for pressurized water reactor containments in the United States.

During normal plant operations and in normal operating temperatures, the hydrogen generation is not significant. When the nuclear fuel overheats, zirconium in Zircaloy cladding used in fuel rods oxidizes in reaction with steam: :Zr + 2H2O → ZrO2 \+ 2H2 When mixed with air, hydrogen is flammable, and hydrogen detonation or deflagration may damage the reactor containment. In reactor designs with small containment volumes, such as in Mark I or II containments, the preferred method for managing hydrogen is pre-inerting with inert gas—generally nitrogen—to reduce the oxygen concentration in air below that needed for hydrogen combustion, and the use of thermal recombiners. Pre-inerting is considered impractical with larger containment volumes where thermal recombiners and deliberate ignition are used.

The MUWC and the makeup water purification and filtering (MUPF) systems were also used to try to cool the suppression pool and drywell in addition to the reactor to prevent the drywell pressure from getting too high. Operators were later able to restore the High Pressure Core Spray portion of the ECCS in unit 4 and switched emergency water injection for unit 4 from the MUWC system to the HPCS. While the water level was maintained in the three cores using emergency water injection, pressures in the containment vessel continued to rise due to lack of suppression pool cooling and the operators prepared to vent the containments making restoration of heat removal urgent. Unit 1 was prioritized as it had the highest drywell pressure.

Other practices predating Spanish conquest include galaide' canoe-making, making of the belembaotuyan (a string musical instrument made from a gourd), fashioning of slings and slingstones, tool manufacture, burial rituals, and preparation of herbal medicines by Suruhanu. Master craftsmen and women specialize in weavings, including plaited work (niyok- and åkgak-leaf baskets, mats, bags, hats, and food containments), loom-woven material (kalachucha-hibiscus and banana fiber skirts, belts and burial shrouds), and body ornamentation (bead and shell necklaces, bracelets, earrings, belts, and combs made from tortoise shells and Spondylus). While only a few masters exist to continue traditional art forms, the resurgence of interest among the Chamorros to preserve the language and culture has resulted in a growing number of young Chamorros who seek to continue the ancient ways of the Chamorro people.

Taking the size effect into account is essential for safe prediction of strength of large concrete bridges, nuclear containments, roof shells, tall buildings, tunnel linings, large load-bearing parts of aircraft, spacecraft and ships made of fiber-polymer composites, wind turbines, large geotechnical excavations, earth and rock slopes, floating sea ice carrying loads, oil platforms under ice forces, etc. Their design depends on the material properties measured on much smaller laboratory specimens. These properties must be extrapolated to sizes greater by one or two orders of magnitude. Even if an expensive full-scale failure test, for example a failure test of the rudder of a very large aircraft, can be carried out, it is financially prohibitive to repeat it thousand times to obtain the statistical distribution of load capacity.

Low risk containment was appropriate for experiments that generated novel biotypes but where the available information indicated that the recombinant DNA could not either alter appreciably the ecological behavior of the recipient species, increase significantly its pathogenicity or prevent effective treatments of any resulting infections. The moderate risk level of containment was intended for experiments in which there was a probability of generating an agent with a significant potential for pathogenicity or ecological disruption. High-risk containment was intended for experiments in which the potential for ecological disruption or pathogenicity of the modified organism could be severe and thereby pose a serious biohazard to laboratory personnel or to the public. These levels of containments, along with the previously mentioned safety measures, formed the basis for the guidelines used by investigators in future experiments that involved the construction and propagation of recombinant DNA molecules using DNA from prokaryotes, bacteriophages and other plasmids, animal viruses and eukaryotes.
