Locations neighborhoods

A growing issue with cyber life and smartphone usage relates to geolocation tools such as Facebook Places. These services have become very popular apps, especially in the social networking environment. The apps allow users to check-in to locations (neighborhood businesses) via their mobile phone. Their location is then sent to their friends and in many cases includes a map showing their exact location. [Pg.67]

It is estimated that the earth s age is in the neighborhood of 4 to 7 billion years. These estimates are basically derived from carbon-14, potassium-40, uranium-235, and uranium-238 dating of earth rocks and meteorites. The meteorites give important data as to the age of our solar system. Geologic time is felt to be represented by the presence of rock intervals in the geologic column (layers of rock formations in vertical depth) or by the absence of equivalent rocks in correlative columns in adjacent locations [25,26]. The two basic factors that are used to determine geologic time are ... [Pg.241]

Points on the zero-flux surfaces that are saddle points in the density are passes or pales. Should the critical point be located on a path between bonded atoms along which the density is a maximum with respect to lateral displacement, it is known as a pass. Nuclei behave topologically as peaks and all of the gradient paths of the density in the neighborhood of a particular peak terminate at that peak. Thus, the peaks act as attractors in the gradient vector field of the density. Passes are located between neighboring attractors which are linked by a unique pair of trajectories associated with the passes. Cao et al. [11] pointed out that it is through the attractor behavior of nuclei that distinct atomic forms are created in the density. In the theory of molecular structure, therefore, peaks and passes play a crucial role. [Pg.127]

To obtain accurate information about the location of the impurity, two factors are important (1) one needs to probe many different, judiciously chosen positions (2) relaxation of the host lattice needs to be included. As an example, the bond center will only show up as a minimum in the total-energy surface for neutral H in Si i/(l) explicit calculations are performed for the impurity in that neighborhood and (2) relaxation of the Si atoms is allowed. Explicit results for location of hydrogen in the lattice will be given in Section III. [Pg.608]

Best Paint is a small Seattle company dedicated to producing safe paint products with a minimum of VOCs. Located in my neighborhood, this gem of a resource is owned and operated by co-founders John Pruitt and John Todd, two men who became chemically sensitive while working in the paint industry. Best Paint is advertised almost solely by word of mouth, and is carried only by a few retail outlets in Seattle special orders are shipped to environmentally ill consumers nationwide. The two owners are always busy making paint... [Pg.192]

We consider the reactive solute system with coordinate x and its associated mass p, in the neighborhood of the barrier top, located at x=xi=0, and in the presence of the solvent. We characterize the latter by the single coordinate. v, with an associated mass ps. If the solvent were equilibrated to x in the barrier passage, so that there is equilibrium solvation and s = seq(x), the potential for x is just -1/2 pcc X2, where (, , is the equilibrium barrier frequency [cf. (2.2)]. To this potential we add a locally harmonic restoring potential for the solvent coordinate to account for deviations from this equilibrium state of affairs ... [Pg.238]

By the use of suitable bifunctional reagents, the local neighborhoods of associated macromolecules can be probed. Studies of this nature do not provide the location of a given site relative to the entire structure, but rather relative to its nearest neighbors. It should also be pointed out that most probes are specific for certain side chains and groups. Where these are lacking, there is a null test for proximity even if molecules are actually in close proximity. [Pg.38]

A particularly notable chronic spill exists in the Greenpoint neighborhood, which lies along Newton Creek in Brooklyn, New York. Petroleum refining has been conducted in this area since 1866. By 1870, more than 50 refineries were located along the banks of... [Pg.802]

The cathode materials employed for the early lithium-based systems were 3.0 V class oxides or sulfides thus, the redox potential for the additive should be located in the neighborhood of 3.2—3.5 V. Accordingly, the first generation redox additive proposed by Abraham et al. was based on the iodine/ iodide couple, which could be oxidatively activated at the cathode surface at 3.20 V and then reduced at the lithium surface. " " " 2° For most of the ether-based solvents such as THF or DME that were used at the time, the oxidation potential of iodide or triiodide occurred below that of their major decompositions, while the high diffusion coefficients of both iodine and iodide in these electrolyte systems ( 3 x 10 cm s ) offered rapid kinetics to shuttle the overcharge current. Similarly, bromides were also proposed.Flowever, this class of halide-based additives were deemed impractical due to the volatility and reactivity of their oxidized forms (halogen). [Pg.134]

This incident resulted in 650 fatalities, more than 6,400 injuries, destruction of the terminal and many of the homes in the neighborhood located adjacent to the terminal. [Pg.383]

The local maxima of 7s(r), the 7s,max, reveal the locations of the most strongly bound electrons. While we have found some evidence that these may be sites reactive toward nucleophiles, this is not well-established. Since 7s,mm and 7s,max are local features, referring to specific points in space, it is quite possible to have one or more of each in the neighborhood of a given atom in a molecule this simply means that there are both tightly and loosely held electrons in different regions around the atom. Some examples wUl be seen later in this chapter. [Pg.8]

Emergency response personnel If the QRA involves consequence estimation, the team will probably need data on the emergency response procedures and capabilities. For example, how quickly could the neighborhood be evacuated, what fraction of the release would be neutralized, and can firefighters extinguish a blaze in that location Expect to commit a few staff-days of effort over the life of the project. [Pg.49]
