PECULIARITIES OF FISH OTOLITHS EPMA AS A PROMISING METHOD TO MONITOR ENVIRONMENT... 

In another promising method, based on the effective Hamiltonian theory used in quantum chemistry [19], the protein is divided into blocks that comprise one or more residues. The Hessian is then projected into the subspace defined by the rigid-body motions of these blocks. The resulting low frequency modes are then perturbed by the higher... 

The xanthate method [62] is considered as one of the most promising methods for industrial chemical modification. The principal involved in the xanthate method of grafting is that cellulosic xanthate either ferrated or in acidic conditions reacts with hydrogen peroxide to produce macroradicals. The following reaction mechanism has been proposed ... 

Another promising method for the preparation of tantalum and niobium oxide precursors involves the precipitation of peroxoniobate and peroxotantalate compounds. 

Nuclear magnetic resonance spectroscopy of the solutes in clathrates and low temperature specific heat measurements are thought to be particularly promising methods for providing more detailed information on the rotational freedom of the solute molecules and their interaction with the host lattice. The absence of electron paramagnetic resonance of the oxygen molecule in a hydroquinone clathrate has already been explained on the basis of weak orientational effects by Meyer, O Brien, and van Vleck.18... 

Impact strength also increased if the adhesion between the polymer and fiber is increased [240, 249]. The most promising method of modification of fiber-filled compositions is by pre-treating the fibers or adding to the matrix of specific depressants or modifiers with the aim of creating a chemical bond at the interphase. This improves the composition service lifetime, strength and thermal stability [250],... 

The formal document that accepts a customer order includes a delivery promise, method and time for payment, and identifies any exceptions to the terms and conditions stated on the customer s purchase order. 

In our laboratory this kind of research has been systematically carried out for a number of years. A certain progress has been made in developing new promising methods for the chemical modification of PAN and acrylonitrile (AN) copolymers, and in creating new types of fibres with technologically valuable properties.

Electric chemical polish (ECP) and electric chemical mechanical polish (ECMP) [53] have been developed as promising methods for global planarization of LSI fabrication and abrasive-free polish. 

Continuous mixing of rubber compounds is a very promising method in order to obtain a more consistent quality at very high levels (e.g., better dispersion and far better consistency). 

The biological activity of several halogenated herbicides in water is destroyed by ultraviolet irradiation (18). Irradiation seems to be a promising method for decontaminating small quantities of pesticides. The chemical similarity between the chlorinated dioxins and other chlo-rinted aromatic compounds suggested that if there were parallels in their photochemical behavior, sunlight might destroy dioxins in the environment. 

The change in the electronic properties of Ru particles upon modification with Se was investigated recently by electrochemical nuclear magnetic resonance (EC-NMR) and XPS [28]. In this work, it was established for the first time that Se, which is a p-type semiconductor in elemental form, becomes metallic when interacting with Ru, due to charge transfer from Ru to Se. On the basis of this and previous results, the authors emphasized that the combination of two or more elements to induce electronic alterations on a major catalytic component, as exemplified by Se addition on Ru, is quite a promising method to design stable and potent fuel cell electrocatalysts. 

A major drawback of this study was that we measured lipid peroxidation ex vivo, but not in vivo using the latest and most promising methods such as F2 isoprostanes (Roberts and Morrow, 2000). However, we are planning to do that soon, so hopefully future studies will bring us more detailed information about the effects of phloem on lipid peroxidation. In conclusion, our study showed that lignans are bioavailable from the wood matrix, that long-term consumption of phloem is safe and that ingestion of phloem can inhibit lipid peroxidation in humans. 

At present, the most promising methods for synthetic colorant analysis seem to be those based on separation approaches such as HPLC and capillary electrophoresis (CE). CE is the method of choice for the determination of synthetic dyes in biological materials while HPLC is generally a more suitable method for the identification and determination of hydrophobic natural pigments, having a better sensitivity and efficiency than CE. 

The measurement of change in the surface potentials of aqueous solutions of electrolytes caused hy adsorption of ionophore (e.g., crown ether) monolayers seems to he a convenient and promising method to ascertain selectivity and the effective dipole moments of the ionophore-ion complexes created at the water surface. 

Ina similarmarmerto surface-enhanced Raman scattering, surface-enhancement of hyper-Raman scattering is a promising method to study adsorbed molecules on metal surfaces [24]. Based on recent developments in plasmonics, design and fabrication of metal substrates with high enhancement activities is now becoming possible [21]. Combination of the surface enhancement with the electronic resonances would also be helpful for the practical use of hyper-Raman spectroscopy. Development of enhanced hyper-Raman spectroscopy is awaited for the study of solid/liquid interfaces. 

A very promising method, immobilized artificial membrane (IAM) chromatography, was developed by Pidgeon and co-workers [299-304,307], where silica resin was modified by covalent attachment of phospholipid-like groups to the surface. The retention parameters mimic the partitioning of drugs into phospholipid bilayers. The topic has been widely reviewed [47,298,307,309-311].
