Entity Loads

In open fibers the fiber wall may be a permselective membrane, and uses include dialysis, ultrafiltration, reverse osmosis, Dorman exchange (dialysis), osmotic pumping, pervaporation, gaseous separation, and stream filtration. Alternatively, the fiber wall may act as a catalytic reactor and immobilization of catalyst and enzyme in the wall entity may occur. Loaded fibers are used as sorbents, and in ion exchange and controlled release. Special uses of hoUow fibers include tissue-culture growth, heat exchangers, and others. [Pg.146]

This is not a distinct clinical entity. The most frequent form of the condition is primarily associated with severe cardiac dysfunction often in combination with dysmorphy. It is confusing, however, because a paralytic attack is accompanied by extrasystoles and tachycardia. Serum may be high, low or normal. A familial form of the disorder is exacerbated by cold and high but is relieved by Na loading. It is, however, not associated with any specific changes in serum K. ... [Pg.317]

Since U and V express one and the same set of latent vectors, one can superimpose the score plot and the loading plot into a single display as shown in Fig. 31,2e. Such a display was called a biplot (Section 17.4), as it represents two entities (rows and columns of X) into a single plot [10]. The biplot plays an important role in the graphic display of the results of PCA. A fundamental property of PCA is that it obviates the need for two dual data spaces and that instead of these it produces a single space of latent variables. [Pg.108]

Synopsis of Experiment and Results. The material is irradiated during straining and relaxation. The example shows that a nanostructure which is hard to interpret from a series of scattering patterns may clearly reveal its complex domain structure after transformation to the CDF. Different structural entities are identified which respond each in a different way on mechanical load. The shape of the basic particles is identified (cylinders). The arrangement of the cylinders is determined. Thus the semi-quantitative analysis of the CDF provides the information necessary for the selection and definition of a suitable complex model which is required for a... [Pg.172]

Shape Change of Structural Entities. In many cases the growing anisotropy is not only a phenomenon of rotating structural entities, but also goes along with a deformation of the structural entities themselves. This case will be studied here. Only affine deformations shall be discussed. In practice, such processes are observed while thermoplastic elastomers are subjected to mechanical load, but also while fibers are spun. [Pg.223]

Of particular importance with the use of LC-NMR as an experimental technique is that it is suited for only a limited number of applications in reference to structure elucidation. As will be discussed in greater detail, the sensitivity issues that arise between the amount of compound one is able to load onto a particular chromatographic stationary phase, and hence elute into the flow-cell of an LC-NMR probe, limit what type of structural analysis that can be performed. It is this author s current opinion that most complete structure elucidations of unknown molecular entities are not amenable to LC-NMR. In these... [Pg.733]

New avenues could come from reacting small chemical entities with the remaining amines at the surface of the lipoplexes, to obtain completely neutralized DNA-loaded particles (57). Gain in circulation time was significant by this so-called postgrafting method. [Pg.289]

Figure 1 Schematic structures of micelle and liposome, their formation and loading with a contrast agent, (a) A micelle is formed spontaneously in aqueous media from an amphiphilic compound (1) that consists of distinct hydrophilic (2) and hydrophobic (3) moieties. Hydrophobic moieties form the micelle core (4). Contrast agent (asterisk gamma- or MR-active metal-loaded chelating group, or heavy element, such as iodine or bromine) can be directly coupled to the hydrophobic moiety within the micelle core (5), or incorporated into the micelle as an individual monomeric (6) or polymeric (7) amphiphilic unit, (b) A liposome can be prepared from individual phospholipid molecules (1) that consists of a bilayered membrane (2) and internal aqueous compartment (3). Contrast agent (asterisk) can be entrapped in the inner water space of the liposome as a soluble entity (4) or incorporated into the liposome membrane as a part of monomeric (5) or polymeric (6) amphiphilic unit (similar to that in case of micelle). Additionally, liposomes can be sterically protected by amphiphilic derivatization with PEG or PEG-like polymer (7) [1].

EntityDictionaryManager has two responsibilities provide entity dictionaries to clients and refresh the entity dictionaries from the data source periodically. The first responsibility is accomplished by its public API—the getters. The second one is accomplished by its private refresh() and load...() methods, and a background thread that wakes up every 30 minutes. [Pg.157]

The class first declares a set of static variables for holding the entity dictionaries. Its private constructor and the static getlnstance() method make it a Singleton. Its load...() methods call EntityDictinaryDao to load the entity dictionaries from the data source. Let us again use personnel dictionary as an example. The code snippet of the loadPersonnel() method is as follows ... [Pg.165]

The static block is executed when the class is loaded into the JVM. Look at what the static block does. It creates an anonymous inner class of type Thread—the refreshThread. Its run() method puts the thread into sleep for a period of time (30 minutes in our code example). When it wakes up, it calls the refresh() method of the EntityDictionaryManager. The static block starts the refresh thread, which means that the entity dictionary refresh is handled by an independent thread. The thread is in an indefinite while-loop that puts the thread into sleep after every entity dictionary refresh. The thread wakes up every 30 minutes and does the next entity dictionary refresh. [Pg.167]

The registry object, defined as an instance variable of the AbstractMapper class, caches the entity objects in a map, the primary key of the object as the key and the object as the value. The abstractFind() method performs a lookup in the registry and returns the object being searched if it is already in the cache. Otherwise it performs a database query, calls the load() method to build tlie entity object, and returns it. [Pg.195]

For such outliers, detection and assessment can actually be accomplished using some of the modeling tools themselves.1,3 In this work, the use of PCA and PLS for outlier detection is discussed. Since the PCA method only operates on the X-data, it can be used to detect X-sample and X-variable outliers. The three entities in the PCA model that are most commonly used to detect such outliers are the estimated PCA scores (T), the estimated PCA loadings (P), and the estimated PCA residuals (E), which are calculated from the estimated PCA scores and loadings ... [Pg.279]
