The direct reaction of 1-alkenes with strong sulfonating agents leads to surface-active anionic mixtures containing both alkenesulfonates and hydroxyalkane sulfonates as major products, together with small amounts of disulfonate components, unreacted material, and miscellaneous minor products (alkanes, branched or internal alkenes, secondary alcohols, sulfonate esters, and sultones). Collectively this final process mixture is called a-olefinsulfonate (AOS). The relative proportions of these components are known to be an important determinant of the physical and chemical properties of the surfactant [2]. 

Some earlier developments and applications of various implantable pH sensors or measurement systems have been reported [128, 129, 130, 131]. However, reliable pH sensors for long-term implantations are still not available, and widespread clinical usage of implantable pH sensors has not been reached. Similar to other implantable sensors, the development of implantable pH microelectrodes, either fully implanted in the body or needle type sensors applied through the skin (percutaneous), has faced serious obstacles including sensor stability deterioration, corrosion, and adverse body reactions [48, 132, 133], Among them, encapsulation to prevent corrosion represents a major challenge for the implantable sensor devices [51]. Failure of encapsulation can cause corrosion damage on internal components, substrate materials, and electrical contacts [48], The dissolution of very thin pH sensitive layers will also limit the stability and lifetime of implantable micro pH sensors.

The description of the dynamics in the intermediate time scale and the corresponding quasi-steady-state constraints involve only the large internal material flows of the column, i.e., V and R. It is easy to verify that these flows do not influence the total material holdup of the column, or the holdup of any of the components in the column and, consequently, the constraints in Equations (7.20) are not linearly independent (more specifically, the last two constraints can be expressed as a linear combination of the remaining constraints).

We start from the flux balance for the B component (core material) at the outer boundary and the flux balance for the A-component (enveloping material) at the internal boundary. Flux balance means that the product of concentration step across the boundary and the boundary velocity is equal to the difference of fluxes on both sides of this moving boundary. For the external boundary, the flux balance for B is more convenient since we know for sure that both the concentration of B and the outward flux of B are equal to zero. On the other hand, for the internal boundary, the flux balance of A is more convenient since we consider the case when the solubility of A in B can be neglected and no A goes into the void so that the corresponding concentration and flux of A at r < n are equal to zero. Thus,... 

If no protective oxide scale can be formed on the surface, or if the scale shows cracks or other types of channels for rapid gaseous transport through the scale, internal corrosion or oxidation can become possible. Besides oxidation, it is mostly internal sulfidation, nitridation, and carburization that are observed under technical conditions. Naturally, internal corrosion is not desired as it changes the optimized mechanical properties of a material. Furthermore, it may lead to grain-boundary weakening, which in time may result in the initiation of surface cracks in the case of stresses in a component. This is usually equal to the end of life of a component. Internal corrosion depends on several prerequisites (Rapp, 1965), as follows ... 

The fibers themselves can be modified significantly in the way they are processed. The emulsion of immiscible liquids which are then electrospun creates fibers with a core of one type and a surface of another type. If the internal material is dissolvable, it creates a hollow core [31]. And additives to the polymer do not have to be removed. Blends of inorganic and organic material, which can be purified [32] or heterogenous extracellular matrix components [33], can add bioactive components for interacting cells or change the material s mechanical and chemical properties. 

Piluso and Ricciuti (2008) classify the symbiotic flows as intermodal (between two firms), internal recycle (a firm reusing its recovered components), raw material (net exogenous input), product stream (net output of usable products), and the net output of waste. They show how an input-output model can be set up, based on Leontief s work (Leontief 1936) on large-scale systems. They use the input-output model to compute the total net waste production, percentage of input raw material, and the percentage of intermediate products that end up as waste. 

Am, Am, etc.). Some of these radionuclides arise from the activation of impurities which were integral with the original graphite components, other radionuclides arise from other reactor materials, which have then been activated elsewhere in the core before being carried around the circuit in the coolant gas [63,64]. The foremost-activated material may be associated with the graphite component internal porosity surfaces, which may be transported deeper into the material via the complex porosity network. Immediately after shutdown is the predominant radionuclide in terms of activity, but with a half-life of 12.3 years this decays relatively quickly and...
