An optical metamaterial (MM) is an articially engineered composite with electromagnetic properties that are determined by subwavelength structuring rather than by the constituent materials. Hence, when rationally designed, metamaterials can demonstrate electromagnetic properties that are unattainable with naturally o…
A new era dawned in the history of medical diagnosis after the discovery of the x-ray by Roentgen. Since the inception of x-ray technology for medical imaging, the invention of noninvasive methodologies and the exploration of their applications in various elds such as clinical diagnosis, cellular 25.3.1.3 Contrast Age…
On 25 January 1958 the journal Nature published a group of papers by both British and American authors containing the latest results in the field of nuclear fusion. The editorial accompanying them was effusive: ‘The announcement of the successful control of the thermonuclear reaction has now been made, and all the scie…
The Sun is a huge nuclear fusion reactor that converts hydrogen to helium. The overall fusion reaction, involving four protons, 1H, and two electrons, leads to the formation of one nucleus of helium, 4He, two neutrinos, ν, and six gamma ray photons, γ. The released large amount of energy is carried mostly by gamma ray…
The aggregation of the initial nanofiller disperse particles is more or less large particles aggregates always occurs in the course of technological process of making particulatefilled polymer composites in general [1] and elastomer composites in particular [2]. The aggregation process acts on composites (nanostructur…
Abstract Processes and equipments that must operate at high temperatures require materials able to face high thermal fluxes, severe stresses, high chemical reactivity. Ultra High Temperature Ceramics (UHTC’s) represent a class of materials most promising for such applications. In particular it is often necessary, to o…
Transition metal (TM) compounds and various rare earth-based compounds have been the workhorse of the strongly correlated community over the past ve to six decades, with very interesting properties being found as a consequence of closely coupled spin, charge, orbital, and lattice degrees of freedom [1-7]. P-band mater…
For moderate to large-sized samples, satisfactory approximations to the variance can be obtained when we replace the expected value of the second partial with actual sample values; that is, 8.1.4 Hazard Plot Estimates Nelson ( 1969) proposed a simple graphical procedure based on a plot of the cumulative hazard functio…
This chapter is an overview of the current state of the science and technology of supercritical fluids. The principal objective is to acquaint the reader with the unusual properties of supercritical fluids, and with the ways some basic principles are essential in understanding the supercritical fluid extraction (SFE) tec…

Physical dimensions of electronic devices are approaching the limit of manufacturing technologies. The elements in new integrated circuitry reached the critical size of 60 nm, which is beyond the limitation of conventional photolithography. Although some methods of lithography, such as electron beam, x-ray, and scanni…
Rarely, if ever, does one radioactive disintegration give rise to one event in a typical Geiger-Müller counter. The efciency of a typical GeigerMüller counter is between 1 and 10%. Some of the factors responsible for this are shown in Figure 11.
Asphaltene deposition is a major problem both upstream and downstream in the petroleum industry.1-5 Asphaltenes can block reservoir pores in the near-well area and deposit in the production tubing and downstream pipeline and facilities.6 Many reservoirs with crudes containing asphaltenes produce without evidence of as…

Weight reduction is one of the most important objectives in the aerospace industry. Reduction in the overall weight of the aircraft contributes to fuel savings, which means a drop in total operational cost. In the aerospace industry, fuel cost amounts to about 35-40% of the total operation expense. A 30% reduction in…
The ECM of cartilage is primarily composed of aggrecan and collagen type II. Aggrecan is a huge proteoglycan consisting of over 100 polysaccharide chains, called glycosaminoglycans (GAGs), attached to a protein core (Alberts et al. 2007). The speci¦c GAG chains found in aggrecan are chondroitin sulfate and keratan sul…
Titanium belongs to the IVA group of elements and is able to form a wide range of oxides. Titanium dioxide (rutile) is the oxide phase of titanium that is thermodynamically stable within a wide range of temperatures and oxygen partial pressures. The other oxide phases of titanium include TiO, Ti2O3, Ti3O5, and the hom…
Before presenting our work, we note with pleasure the extensive work [33] performed by Professor B. M. Deb and his students on excited-state calculations for atoms by employing the Harbola-Sahni exchange potential [34,35]. We feel honored to have been invited to write a chapter in a book dedicated to Professor Deb.
India was one of the pioneers to initiate coffee cultivation and trade in the early years of the seventeenth century. The history of coffee cultivation in India appears to be a very fascinating saga and a bit of a conundrum for the present generation. According to legends, Arabica coffee was introduced into India in 1…
