Pre-deployment

The process of rollout is divided into three phases - pre-deployment, deployment, and post-deployment - for the ease of understanding. Pre-deployment involves planning and preparation for the program rollout. Deployment involves the dehvery... [Pg.183]

The pre-deployment hazard assessment must take into account the presence of hazards across all of the different agreed possible uses of the deployed system. The assessment is divided into two parts ... [Pg.62]

The chronology of the development of nuclear reactors can be divided into several principal periods pre-1939, before fission was discovered (12) 1939—1945, the time of World War II (13—15) 1945—1963, the era of research, development, and demonstration (16—18) 1963—mid-1990s, during which reactors have been deployed in large numbers throughout the world (10,18) and extending into the twenty-first century, a time when advanced power reactors are expected to be built (19—23). Design of nuclear reactors has been based on a combination of theory, measurement of basic and derived parameters, and experiments with complete systems (24—27). [Pg.211]

Resources are not limited to human resources, as stated in Part 2 Chapter 1. You need to ensure that the design groups are equipped with the necessary design tools, equipment, and facilities with which to execute the tasks. Once you have asked each group to propose how they are to meet the requirements, you then need to ensure that they have the capability of doing so. This is less of a problem in-house as with subcontractors. Due to their remoteness and the keen competition, they may make claims they cannot fulfill. In controlling the design you need to ensure that adequate resources are deployed by the subcontractors and to do this pre-contract surveys and assessments need to be performed. This is implied in clause 4.6. [Pg.241]

The major chemical problem met in ion-exchange practice is the fouling or poisoning of the anion resins by organic matter. The various counter measures deployed include pre-flocculation, oxidation of the organic material, the use of specially developed resins, and treatment of the fouled resins by brine and/or hypochlorite. [Pg.834]

However, current forms of LOAC devices have many components external to the microfluidic chip such as valves, pumps, power supplies, electronic circuitry, and reagent/waste storage units. While these devices are a major advance on pre-existing autonomous instruments and could be deployed on a reasonable scale, they are typically too large, consume too much power and are too expensive for high-density deployment. [Pg.139]

The sequence of operations is as follows Azimuth and range to the target are determined. Hie primary fuze is set and the correct amount of propint charge is loaded into the gun to deliver the round to the area above the target. Launch setback activates the safe and arm device. As the projectile continues on its ballistic path, the pre-set primary fuze initiates when the round passes into the desired delivery area. Primary fuze initiation causes an expl pusher charge to eject the three submunitions from the aft end of the round, which continues on its trajectory. After ejection, a de-spin mechanism slows the speed to allow for parachute deployment. Once de-spin occurs, the vortex ring parachute is deployed, initiating... [Pg.233]

Electrode surface activation can be improved simply by electrochemical pretreatment. Determination of nitroaromatic compounds in water and soil spiked samples have been reported at electrochemically activated carbon-fiber microelectrodes. No interference was found from compounds such as hydrazine, phenolic compounds, carbamates, triazines or surfactants. The detection limit obtained can be approximately 0.03 iigml-1 for all the nitroaromatic compounds (Agui et al. 2005). Chen and coworkers reported an effective field-deployable tool for detecting nitroaromatic compounds with an electrochemically pre-anodized screen-printed carbon electrode (SPE) (Chen et al. 2006). [Pg.74]

Allylation reactions can be designed to effect high stereoselectivity in the case of chiral /3-alkoxy aldehydes, in which the ether oxygen provides for effective coordination with a Lewis acid. Multi-valent, oxophilic Lewis acids serve to pre-organize the aldehyde substrate in a six-membered chelation complex. As in the examples of a-chelation control, an open transition state is deployed with synchnal or antiperiplanar orientations based upon the consideration of steric interactions with placement of the small (hydrogen) vinyl substituent of the allylic stannane over the preformed metallocycle. Several examples are illustrated in Scheme 5.2.20. i... [Pg.524]
