  • Characterizing the nature of heavy metal release reactions, sorption mechanisms, and movement in the soil is the main topic of this book. Because soils are heterogeneous, heavy metals in soils can be involved in a series of complex chemical and biological interactions including oxidation-reduction, precipitation and dissolution, volatilization, and surface and solution phase complexation. The heterogeneous nature of the different soil constituents adds to the complexity of interactions of heavy metal species with the soil environment....

  • Producers are also avid users of social media. Historically, producers have networked within a defined geographic territory. Because people generally only buy from producers they trust, developing trust has generally meant face-to-face interaction. However, as people grow more accustomed to trusting relationships developed online, producers who excel at developing such relationships will likely pursue licenses and sales opportunities outside traditional geographic areas.

  • Since their first introduction, metallic biomaterials have always been designed to be corrosion resistant. For decades, this paradigm has become the mainframe of the biomaterials world. It has been cited in thousands of scientific papers and taught in hundreds of courses of materials for biomedical devices. It has also been followed by industries in developing millions of medical devices until today. Nowadays, with the advent of tissue engineering, biomaterials are envisaged to actively interact with the body.

  • Porous metal organic framework nanoscale carriers as a potential platform for drug delivery and imaging, In the domain of health, one important challenge is the efficient delivery of drugs in the body using non-toxic nanocarriers. Most of the existing carrier materials show poor drug loading and or rapid release of the proportion of the drug that is simply adsorbed at the external surface of the nanocarrier.

  • The dispersion equations for phonon frequencies with wave-vector components parallel to the wire are obtained. After having quantized the phonon field we derive the Frohlich Hamiltonian describing the electron–LO-phonon interaction. The influence of the thickness of the barrier layer as well as the thin metallic shell on the phonon frequencies and their interaction with electrons is studied.

  • In this work, we follow that idea to investigate the quasi onedimensional system of metallic carbon nanotubes. Due to the linear dispersion law, the non-interacting Bose and Fermi gases in metallic carbon nanotubes are equivalent. This equivalence could be applied to the gas systems of exciton photon (Bose particles) and electron hole (Fermi particles) in metallic carbon nanotubes.

  • The W-E BDEs trend in tetrylene complexes W5- NHEMe is opposite to that of the W5-EP2 complexes which decrease from the lighter to the heavier homologues. The NHEMe ligands are strong -donors and weak π-acceptors. NOCV pairs were used in a description of the chemical bond between the W(CO)5 fragment and the ligands in the transition-metal complexes and the results indicated that the NOCV pairs lead to very valuable description of the bonding situation of the fragment-ligand bond in complexes.

  • The discovery of anticancer activity in cisplatin triggered the development of novel drugs containing metals such as platinum or ruthenium. Extremely diverse structural chemistry and the interaction of metal complexes with biomolecules resulted in the exploration of novel metal complexes with drug potential.

  • Contraceptive use accounts for a substantial portion of the variation in observed fertility rates (others include age of marriage, abortion rates, post- partum amenorrhea and abstinence, and occurrence of marital separations). Although there have been dramatic increases in the use of family planning services, unmet need for family planning remains very high in low-prevalence regions.

  • At its inception, the original plan for this symposium was to emphasize the medical aspects of inorganic chemistry, rather than to go over once more new developments in bioinorganic chemistry, important as the subject is, since the latter topic has been treated many times in recent symposia reviews and monographs.

  • Under the Pharmaceutical Zero-for-Zero Initiative, which entered into force in 1995, the United States and its major trading partners eliminated tariffs on many pharmaceuticals, their derivatives, and certain chemical intermediates used to make pharmaceuticals. The U.S. list of pharmaceutical products and chemical intermediates that are eligible for duty- free treatment under the agreement is presented in the Pharmaceutical Appendix to the Harmonized Tariff Schedule of the United States.

  • As rates of deforestation and land degradation, and losses of biodiversity and ecosystem services, continue to rise globally, the international community is faced with the challenge of finding land use interventions that can mitigate or reduce the impact of these environmental issues. Agroforestry, the integration of trees in farming systems, has the potential for providing rural livelihoods and habitats for species outside formally protected lands, connecting nature reserves, and alleviating resourceuse pressure on conservation areas.

  • Why did I decide to write this book? As an undergraduate student I could not make up my mind whether I wanted to be a zoologist or a botanist, so I decided to adopt ecology, in its broadest sense, as my area of interest. This led me to think about interactions among organisms and to try to look at ecosystems from a holistic, rather than from an autecological, point of view. As someone with little formal training in mycology, my interest in fungi started during my doctoral research, especially when attending university-wide lectures by C. T. Ingold, given at the University of London.

  • In order to predict hardening stresses quantitatively, it is necessary to consider interactions among various factors. As shown in Fig. 23, these include: (1) phase transformations, (2) latent heat, (3) thermal stress, (4) transformation stress and plasticity, (5) heat generation due to deformation, and (6) mechanically induced transformation.

  • Science seeks to understand and explain our world, be that its physical composition (geology), chemical composition (chemistry), the way its composite matter interacts (physics), or the organisms that inhabit it (biology). We can only get an idea of what life is all about by piecing together information from each discipline to give us the big picture. We don’t have to look very far to realize that it is difficult, if not impossible, to separate biology from chemistry. After all, our body is a bag of chemicals.

  • Many visual devices and gadgets preceded cinema, too many to list here in detail. A widespread and well-known one was the camera obscura, first constructed in 1645, which projected views in a dark room, for painters. Around the same time Anastasius Kircher built a special room to project images with mirrors, which looked somewhat like a cinema. A specialised building with many people using specialised equipment was necessary to project the images.
