This paper is organized as follows some aspects of Alzheimer s disease are analyzed in the next section. Section 3 is devoted to non-invasive methodologies oriented to early diagnosis. The used methods and resources are described in Sect. 4. In Sect. 5, experimental results are presented. Finally, Sect. 6, is devoted to conclusions and future work. 

This chapter is subdivided into 4 main parts. The first part introduces the fundamental principles of toxicokinetics and toxicodynamics, and their importance for risk assessment, with particular emphasis on mixtures. The second part describes the state of the art in toxicokinetics, and the third part in toxicodynamics. Both later sections focus on how each aspect is dealt with in human toxicology and ecotoxicology. The differences and limitations in each field are addressed. Finally, a general discussion, conclusions, and recommendations for future research explore the application potentials of these approaches, with particular attention to cross-fertilization between human toxicology and ecotoxicology, and where they may hold some promises. 

We open with a brief report of the early discovery of the occurrence and isolation of these proteins and the elucidation of their function and homology, followed by a brief discussion of some problems in their isolation and the determination of their activity. We then consider various aspects of their three-dimensional structures and their significance. We summarize studies on the implications of their sequence similarities, and also on the binding of metal ions, especially calcium(H), and consider their implications. Then follows a brief discussion of lactose synthase, an enzyme of which a-lactalbumin and galactosyltransferase are essential components. We then examine the evidence concerning the evolution of the two proteins, about which there are conflicting views (see Section X,B). Some conclusions and predictions of future directions are made. 

Discussion How the conclusions fit in with previous literature, and what the implications are for future research. Any limitations of the study are also a legitimate (and useful) aspect of this section. 

The paper is organized as follows. In Section 2, the main aspects of the TFD/.W method applied to spherical - hard and soft - cages are presented followed by a discussion on the origin of the quantitative corrections to previous work. Also, in this Section, the treatment of hard-wall spheroidal confinement is presented and applied to the case of C and Ne. Section 3 deals with confinement by an open boundary - a plane in this case - showing sample calculations for C and Ne. Finally, in Section 4 the conclusions of this work are presented and future directions are envisaged. Atomic units are used throughout unless otherwise stated. 

This review deals with both the theoretical and practical aspects of the use of ESR spectroscopy in molecular sieve science. No attempt has been made to compile an exhaustive list of references to all the work that has been published so far. Rather, we have selected what, we feel, are the most important developments and also, where possible, we have drawn examples from our own work. In a first part, the ESR technique and its extensions such as ENDOR and ESEEM, will be highlighted with special emphasis on the principles of the techniques and the instrumental requirements. Attention will also be given to spectral simulation and to quantitative analysis. In a second part, the general features of ESR spectra of transition metal ions in molecular sieves are analyzed. In addition, some remarks will be made on paramagnetic metal clusters and on paramagnetic molecules. The chapter closes with general conclusions and an outlook into the future. For detailed explanations and discussions-in-depth, we refer to several excellent text books [1-9] and review papers [10-14]. 

Several aspects of AFM and its applications to rubbery materials were discussed and illustrated in this chapter. Despite a definite advance in this field during the last 10 years, there is plenty of room for more improvement of this method that will further broaden its use. In conclusion, we would like to mention several future capabilities. 

In conclusion, one could say that despite the lack of experimental data with which the copolymer model predictive powers could be tested, its trends when applied to the VCM/VAc system were very reasonable and in agreement with general experience from systems of this type. There are certain aspects of the model (e.g. the expression for the xc of the system) that should be refined in the near future, but at least the basic structure... 

In this chapter, we will discuss electrochemical sensors based on CNTs. First, the properties and structures of CNTs, the preparation and purification of CNTs, and the advantages of electrochemical sensors based on CNTs are described, then, the fabrication of electrochemical sensors based on CNTs, applications of electrochemical sensors based on CNTs, and the spectroscopic characterization of CNT sensors are described. In conclusion, we will look into some aspects of the future direction for CNT sensors in clinical and biomedical research. 

The article is organized as follows. The main features of the linear response theory methods at different levels of correlation are presented in Section 2. Section 3 describes the calculation of the dipole and quadmpole polarizabilities of two small diatomic molecules LiH and HF. Different computational aspects are discussed for each of them. The LiH molecule permits very accurate MCSCF studies employing large basis sets and CASs. This gives us the opportunity to benchmark the results from the other linear response methods with respect to both the shape of the polarizability radial functions and their values in the vibrational ground states. The second molecule, HF, is undoubtedly one of the most studied molecules. We use it here in order to examine the dependence of the dipole and quadmpole polarizabilities on the size of the active space in the CAS and RASSCF approaches. The conclusions of this study will be important for our future studies of dipole and quadmpole polarizabilities of heavier diatomic molecules. 

Summing up, ECL investigations seem to have a brilliant future because there are many places for the fundamental as well as applied research on this exciting border between electrochemistry and photochemistry. Exponential growth of published papers devoted to different aspects of ECL technique as observed in the past years seems to support the above conclusion.
