The purpose of research was obtaining fire retardant coatings based on perchlorovinyl resin with improved adhesive properties to protect fiberglass plastics. The article presents the results of studies on the influence of a modifier based on the phosphorus-boron-nitrogen-containing oligomer (PEDA) and filler, which is…
The incorporation of polymeric scaffolds in tissue regeneration occurred in the early 1980s, and it continues to play a vital role in tissue engineering [1-3]. The function of a degradable scaffold is to act as a temporary support matrix for transplanted or host cells so as to restore, maintain, or improve tissue. Sca…
The following equations and formulas, established in Chapters 8 and 9 for prismatic line members are expected to give reasonably accurate values for the components of 1displacement and stress, of tapered members provided that the rate of change (dA/dx ) of 1the area of their cross sections is not very large. The error…
Scaffolds used for tissue engineering include both biologic and synthetic materials. Some common biologic materials include decellularized extracellular matrix and puri¦ed natural polymers such as collagen and ¦brin. Common synthetic materials for tissue engineering include polylactic acid, polyglycolic acid, and thei…
The understanding of the behavior of nanoparticles in electric fields requires a knowledge of not only their average electric charge but also their dipole moments. The description of the electric dipole moments of nanoparticles, including macromolecules is much more complicated than that for simple molecules. Permanen…
This chapter discusses the ways in which information is being assembled in species diversity databases and combined to build comprehensive sources of biodiversity knowledge. Much of the chapter is drawn from the author’s experiences with biodiversity data in various projects. The manual processes by which data were me…
The optical and dielectric properties of liquid crystals are generally determined by the rigid core of the molecules. The difference in optical tilt angle between the two states is considerably reduced from that in the bookshelf structure, and is typically between one half and one third of that available in the booksh…
The National Environmental Policy Act (NEPA) regulations (Regulations) were primarily written with the objective of specifying regulatory requirements governing preparation of Environmental Impact Statements (EISs). The focus was clearly on preparing EISs. Given this focus, only limited attention was devoted to descri…
Arcs are self-sustaining DC discharges, but in contrast to glow discharges they have low cathode fall voltage of about 10 eV, which corresponds to the ionization potential. Arc cathodes emit electrons by intense thermionic and field emission; these are able to provide high cathode current already close to the total di…
Since the discovery of the piezoelectric effect of crystals by Pierre and Jacques in 1880, a signifi cant progress has been made both in terms of the material itself and its applications. Piezoelectricity is an electromechanical phenomenon that involves interaction between the mechanical (elastic) and the electrical b…
Numerous pharmacological active compounds have been discovered, isolated, and synthesized in the last few decades. Many of these promising compounds did not advance beyond the laboratory bench to the clinical setting because of dif culties in nding a suitable delivery system. The colloidal drug delivery system (DDS) p…
Technological and social developments of humankind have been well supported by the discovery of new sources of energy and its proper application in day-to-day life. Since the rst installation of electricity grids by Edison, Tesla, and Westinghouse almost 130 years ago, our society has been driven by this source of en…
In his comprehensive article on the historical development of stability theory, Michel points to a number of milestones that in±uence the evolution of the theory of feedback control: Michel, A.N., Stability: The common thread in the evolution of feedback control, IEEE Control Sys. Mag., 16, 50-60, 1996.

In living cells, the lamellar-nonlamellar transitions are fundamentally important in modulating the physicochemical properties of biomembranes and consequently in regulating different biological processes (Landh, 1995; Luzzati, 1997; Patton and Carey, 1979; Simidjiev et al., 2000). In this respect, it is important to…
The union of two amino acids to form a peptide requires suppression of the reactivities of the functional groups that are not incorporated into the peptide bond (see Section 1.5). This is achieved by combining each group with another compound in a manner that allows removal of the added moieties at will. These moietie…
The functional life of the tooth is determined by the vitality of the dentin-pulp complex. The importance of maintaining the vitality of the dental pulp after pathological changes in the hard tissue of a tooth caused by mechanical trauma or chronic irritation (carious lesions) is thus well accepted. The pulp maintains…
Modern offshore structures, including ships, require high-strength structural girders/plates/tubulars/ shells and other lightweight structural components, over large portions of the structural envelope for weight reduction, better stability, increased payload, increased mobility, and survivability. During their servic…
