Objects treated

Object Treats an entire group of objects (such as a component or subsystem or corporation) as if it were a single one, characterizing its behavior with a type. How do the constituent objects (and their actions) correspond to the abstract object (and its actions) ... [Pg.242]

Glowing Auras The creature sees bright auras of color around other creatures and objects. Treat as Dazzled for game purposes. [Pg.8]

The red imported fire ant (Solenopsis invicta) is a widely distributed pest in the southern USA. There exists a queen-recognition pheromone of S. invicta, which attracts worker ants, and causes them to bring inanimated objects treated with queen extracts into their nests as if they were real queens. One of the... [Pg.143]

Sustained intraocular dexamethasone delivery has been shown to effectively treat uveitis in a rabbit model (10). Masked observers graded intraocular inflammation and retinal function was evaluated by electroretinography (ERG). Eyes that received a sustained-release dexamethasone device had significantly reduced clinical signs of intraocular inflammation when compared with control eyes that received a sham device. Objectively, treated eyes had lower protein concentrations and leukocyte counts than control eyes. Furthermore, untreated eyes had significantly depressed ERGs and more histological evidence of tissue inflammation when compared with treated eyes (Fig. 5). [Pg.208]

Reports of the first wooden object treated by freeze-drying in the mid-1950s refer to a 3-m-long 8000-year-old oak canoe from the Netherlands 12, 13), research in the Soviet Union around the same time (14), and European trials at other centers (15). Similar work was done in London (16). All of these projects used a simple system of freezing without pretreatment, followed by... [Pg.237]

Amido black is a protein stain that may be applied to fingermarks in blood to improve contrast. Blood marks, on either porous or nonporous surfaces, are treated by immersion in a methanolic solution of the stain. The surface is then washed in three destaining solutions to reveal enhanced marks that are dark blue in color. Although the technique is quite effective on nonporous objects, treated marks on porous surfaces such as paper and wood tend to show less contrast due to background staining. [Pg.1681]

The percolation models discussed so far undergo piuely geometrical transitions because the objects treated have no center of mass translational motion. They are only randomly placed either on the lattices or in the continuum space. Therefore, they don t reveal any thermodynamic singularities. If particles are moving in a space, however, the entropy associated with the translational motion may partly vanish at the percolation point since the mass center of the infinite cluster (gel) ceases to move. If its derivative with respect to the concentration across the percolation point has a discontinuity, the transition becomes a real thermodynamic one. [Pg.277]

Schawe, 2003). The transition being measured depends critically on the current state and thus history of the material, both thermal and chemical (Doumenc et al., 2008). Current measurement specifications therefore specify a heating pretreatment in order to reduce the effects of the previous history and provide a standard, reproducible, value. As a result, many of the past Tg values of bulk polymers given in the literature cannot be directly compared with currently measured values. For instance, the of PVAC has apparently risen from =24 to =32 °C in recent years without any chemical change. The importance of the history of the sample has implications for objects treated with polymers, whose properties are determined by the history and may not be comparable to the bulk properties as measured by the standard methods. This may account for the unexpected Tg values of PVAC and Paraloid B-72 cast from solvent (Hansen, 1995) and an observed of =60 °C for a 40-year-old PVAC picture varnish (Hansen, 1996). [Pg.40]

Atmospheric plasma reactor designs can vary considerably for web and 3-D object treating. However, there are several similar sub-systems ... [Pg.91]

Bronze disease necessitates immediate action to halt the process and remove the cause. For a long time, stabilization was sought by removal of the cuprous chloride by immersing the object in a solution of sodium sesquicarbonate. This process was, however, extremely time-consuming, frequentiy unsuccesshil, and often the cause of unpleasant discolorations of the patina. Objects affected by bronze disease are mostiy treated by immersion in, or surface appHcation of, 1 H-henzotriazole [95-14-7] C H N, a corrosion inhibitor for copper. A localized treatment is the excavation of cuprous chloride from the affected area until bare metal is obtained, followed by appHcation of moist, freshly precipitated silver oxide which serves to stabilize the chloride by formation of silver chloride. Subsequent storage in very dry conditions is generally recommended to prevent recurrence. [Pg.425]

Nonspecific immunosuppressive therapy in an adult patient is usually through cyclosporin (35), started intravenously at the time of transplantation, and given orally once feeding is tolerated. Typically, methylprednisone is started also at the time of transplantation, then reduced to a maintenance dose. A athioprine (31) may also be used in conjunction with the prednisone to achieve adequate immunosuppression. Whereas the objective of immunosuppression is to protect the transplant, general or excessive immunosuppression may lead to undesirable compHcations, eg, opportunistic infections and potential malignancies. These adverse effects could be avoided if selective immunosuppression could be achieved. Suspected rejection episodes are treated with intravenous corticosteroids. Steroid-resistant rejection may be treated with monoclonal antibodies (78,79) such as Muromonab-CD3, specific for the T3-receptor on human T-ceUs. Alternatively, antithymocyte globulin (ATG) may be used against both B- and T-ceUs. [Pg.42]

Although the size separation/classification methods are adequate in some cases to produce a final saleable mineral product, in a vast majority of cases these produce Httle separation of valuable minerals from gangue. Minerals can be separated from one another based on both physical and chemical properties (Fig. 8). Physical properties utilized in concentration include specific gravity, magnetic susceptibility, electrical conductivity, color, surface reflectance, and radioactivity level. Among the chemical properties, those of particle surfaces have been exploited in physico-chemical concentration methods such as flotation and flocculation. The main objective of concentration is to separate the valuable minerals into a small, concentrated mass which can be treated further to produce final mineral products. In some cases, these methods also produce a saleable product, especially in the case of industrial minerals. [Pg.401]

Raw juice is heated, treated sequentially with lime (CaO) and carbon dioxide, and filtered. This accomplishes three objectives (/) microbial activity is terminated (2) the thin juice produced is clear and only lightly colored and (J) the juice is chemically stabilized so that subsequent processing steps of evaporation and crystalliza tion do not result in uncontrolled hydrolysis of sucrose, scaling of heating surfaces, or coprecipitation of material other than sucrose. [Pg.26]

There should be sufficientiy large numbers of animals to allow a quantitative determination of the average response and the range of responses, including the demonstration of hypersensitive populations. When objective procedures are undertaken, these should be sufficient to allow vaUd statistical comparison to be made between treated and control groups. [Pg.235]

Adsorbents. Acid activated clays have been widely used to treat mineral, vegetable, and animal oils. The primary objective of such treatment is decolorization and, at least in the case of edible oil, to remove components that contribute to off-tastes. Typically the oil is filtered through a granular clay product or treated with finely ground clay and subsequendy filtered. [Pg.210]

The strength of molecular mechanics is that by treating molecules as classical objects, fliUy described by Newton s equations of motion, quite large systems can be modeled. Computations involving enzymes with thousands of atoms are done routinely. As computational capabilities have advanced, so... [Pg.91]

Vapor-phase inhibitors are volatile compounds that adsorb onto metal surfaces, and retard or prevent corrosion by a variety of mechanisms (37). Inhibitors such as dicyclohexamine nitrate [3882-06-02] can protect a variety of metals such as steel, aluminum, and tinplate. A number of vapor-phase inhibitors are commercially available as powders or tablets. However, vapor-phase inhibitors attack nonferrous metals to varying degrees, thus the manufacturers recommendations should be checked before appHcation. The system to be protected must be closed to maintain the volatile compound, but objects as large as the interior of an ocean-going tanker have been treated by this technique. [Pg.283]

Inequality Constrained Problems To solve inequality constrained problems, a strategy is needed that can decide which of the inequality constraints should be treated as equalities. Once that question is decided, a GRG type of approach can be used to solve the resulting equality constrained problem. Solving can be split into two phases phase 1, where the go is to find a point that is feasible with respec t to the inequality constraints and phase 2, where one seeks the optimum while maintaining feasibility. Phase 1 is often accomphshed by ignoring the objective function and using instead... [Pg.486]
