    Abstract: Medicinal and aromatic crops (MACs) are high-value crops since the natural products obtained from them are low-volume high-value commodities that have numerous applications in various sectors such as the food, beverage, food supplement, flavor and fragrance, perfumery and cosmetics, pharmaceutical and aromatherapy industries. In addition, the plant biomass is used in the production of teas and medical applications in traditional and also modern medicines. MACs are important mainly because they contain plant secondary metabolites such as essential oils, alkaloids, glygosides, saponins, tannins, vitamins and other bioactives. Plant secondary metabolites are differentiated from plant primary metabolites of photosynthesis and respiration since they are directly involved in growth and development of plants. Some MACs are used as spices and culinary herbs since they contain mainly essential oils, and are used as tonic to the digestive system, appetite modification and other systems and may facilitate nutrient uptake and utilization from various foods. A significant amount of MACs and their natural products have also demonstrated antimicrobial, antifungal and bactericidal activity and significant antioxidant capacity. In the past, MACs and their natural products have been used as a source for various medicines, in food and beverage production and in aroma products. Essentials of Medicinal and Aromatic Crops summarizes the current knowledge on medicinal and aromatic crops, including the agronomical practices of important MACs and their products, their beneficial effects and utilization of MAP and their products. The chapters provide a comprehensive guide to the most important and used medicinal and aromatic crops and their use in functional foods, nutraceuticals and as bioactives against various ailments, providing researchers, teachers, chemists, food scientists, agronomists and agroecologists in academia, industry and government a fully up to date singular source on this important topic. .

    Abstract: Plants produce chemicals as part of their normal metabolic activities. These include primary metabolites found in all plants, such as sugars and fats, as well as secondary metabolites, which can have therapeutic effects in humans and be refined to produce drugs. Plants synthesize a bewildering variety of phytochemicals, but most are derivatives of a few biochemical motifs. Numerous herbal-derived substances have been evaluated for their therapeutic potential. These include alkaloids, coumarins, saponins, plant pigments and flavonoids. Flavonoids, carotenoids and anthocyanins are probably the best known of these substances due to their antioxidant properties. Carotenoids: Structure and Function in the Human Body presents comprehensive coverage of carotenoids. The text covers the scientific literature and clinical significance of this organic pigment, with an emphasis on its therapeutic potential. The authors approach carotenoids from a range of perspectives, from their structural and physicochemical properties to their distribution in nature, interaction with the human metabolism, and use as a coloring agent in various products. The intake, metabolism and secretion of anthocyanins in the human body are covered in-depth, as are the biosynthetic pathways through which these compounds are synthesized in the natural system. Factors affecting stability and extraction are listed, and health-related uses and biological activities are covered in great detail. Present and future trends in carotenoid research are also presented. This book provides a solid background in carotenoids for researchers and professionals in food science, food technology, nutrition, biology, chemistry and medical sciences.

    Abstract: Due to their high nutritive value and the presence of secondary metabolites, wetland plants can be consumed by humans as food and utilized as medicinal drugs. Significant numbers of ethno-botanic resources have been reported to extract useful compounds, which can be used as pharmaceuticals. Wetland plants are also very valuable as an energy source, as fuel for fish smoking and for domestic energy. These plants can be harvested as wild stock, or cultivated in flooded paddies for aquaculture, food and for livestock fodder. All parts of plants can be utilized for foodstuff, compost, mulch, medicine, and for construction. Wetland Plants: A Source of Nutrition and Ethnomedicine aims to promote public understanding of this remarkable resource, exploring not only their role in the ecosystem but also their nutritional and medicinal purposes. Based on original research, the text focuses on species identification (with original pictures of wetland plants including morphological features), nutritive value and ethno-medicinal uses. This book serves as an important and basic reference material for further research into the basic biological as well as the applied medicinal aspects of traditional medicinal wetland plants.

    Nonlinear transport processes in disordered media (1993)
    Hoboken, NJ : Wiley-Blackwell
    AIChE Journal 39 (1993), S. 369-386 
    Details
    ISSN: 0001-1541

    Notes: Nonlinear transport processes in disordered systems such as porous media and heterogeneous solids are studied, which are represented by two- or three-dimensional networks of interconnected bonds, by a Bethe network (a branching network with no closed loops) of a given coordination number, or by a continuum in which circular or spherical inclusions have been inserted at random. The bonds represent the pores of the pore space, or the conducting and insulating regions of a disordered solid, to which we assign effective properties (radii or conductances) selected at random from a probability density function. Three types of nonlinear transport processes are considered. (1) The relation between the current q and the potential gradient v is of power-law type (as in, for example, flow of power-law fluids or the electric current in doped polycrystalline semiconductors). (2) The relation between q and v is piecewise linear, characterized by a threshold (as in flow of Bingham fluids or in mechanical or dielectric breakdown of composite solids). (3) A large v is imposed on the system, so that a linear transport theory is not valid. The behavioral study of the effective transport and topological properties of the system, such as the permeability, conductivity, diffusivity, and the shape of the samplespanning cluster of conducting paths shows that in all cases the concepts of percolation theory play a prominent role, even if the system is well connected and percolation may seem not to play any role. For most cases, new effective-medium approximations (EMAs) are derived for estimating effective transport properties. Compared to the case of linear transport, new EMAs are considerably more accurate in predicting the scaling properties of the transport coefficients near a critical point such as the percolation threshold. For a power-law transport process, an exact solution is also derived for the Bethe networks. Using the concepts of percolation theory, scaling laws relating the effective properties to various regimes of transport and to topological properties of the system are also given. A relation between the volumetric flow rate of a power-law fluid in porous media and the macroscopic pressure drop is derived, which contains no adjustable parameter and is valid at any porosity. To test the accuracy of our analytical predictions, Monte Carlo simulations are carried out for several cases. In most cases, good agreement is found between the simulation results and predictions. The extension of the results to other types of nonlinearities is also discussed.

    Molecular dynamics simulation of diffusion in pillared clays (1995)
    Hoboken, NJ : Wiley-Blackwell

    Details
    ISSN: 0001-1541

    Notes: The thermodynamics and transport properties of Lennard-Jones particles in pillared catalytic clays are studied by molecular dynamics simulation. The clays are represented by parallel sheets separated by a given distance and connected by pillars of a given size. Two different spatial distributions of the pillars are studied to determine their effect on the properties of the system. Calculations did not indicate a strong dependence of the diffusivity on the spatial distribution of the pillars, except at low porosities. The solvation force increases monotonically with decreasing porosity of the clays and increasing density of the molecules. The percolation threshold ϕc of the system is estimated from the diffusivity measurements in the limit of infinitely low sorbate densities. Near ϕc the diffusivity D vanishes according to the power law, D ˜ (ϕ - ϕc)n, where ϕ is the porosity of the system, and n is a universal constant. The simulations yield n ⋍ 1.7. Since 2- percolation systems require n ⋍ 1.3 and 3-D systems n ⋍ 2.0, pillared clays behave as a system with an effective dimensionality between 2 and 3.

    Effect of long-range correlations on transport phenomena in disordered media (1995)

    Notes: Three different flow and transport phenomena considered here are hydrodynamic dispersion in heterogeneous porous media and aquifers, transport of passive particles in an oscillating flow field, and miscible displacement processes in heterogeneous reservoirs. At microscales all three phenomena are described by the classical convective-diffusion equation (CDE). The presence of long-range correlations at macroscales gives rise to a rich variety of phenomena that cannot be predicted by analyzing the CDE by classical methods. In particular, a new percolation model with long-range correlations provides a rational explanation for the hitherto unexplained field-scale experimental data for hydrodynamic dispersion in porous media and aquifers. Moreover, for transport in oscillating flow in convection cells percolation provides a novel relation between the dispersion coefficient and the Péclet number that cannot be predicted by other methods.

    Asphalt flocculation and deposition: I. The onset of precipitation (1996)

    Notes: Formation of asphalt aggregates and their deposition on the pore surfaces of a porous medium, which alter the structure of the medium and its effective properties, is a critical problem to catalytic and oil recovery and refinery processes. Extensive new experimental data for the amount of precipitated asphalt formed with crude oil and various solvents are presented. Results indicate that, contrary to the previous assumptions, asphalt formation is at best partially reversible. A thermodynamic model based on the Flory-Huggins theory of polymer solutions is used, together with the Soave equation of state, to predict the data. Critical evaluation of the model shows that its predictions do not agree well with our data. As an alternative, we propose a new model that employs a scaling equation, somewhat similar to those encountered in aggregation and gelation phenomena. The scaling function takes on a very simple form, and its predictions are in very good agreement with the data. It also predicts that the onset of precipitation may obey a simple universal equation.

    Asphalt flocculation and deposition: II. Formation and growth of fractal aggregates (1996)

    Notes: Extensive small-angle X-ray and neutron-scattering data, as well as results of precipitation measurements, are analyzed to delineate the structure of the asphalt and asphaltene aggregates that are formed when a solvent is injected into a system containing crude oil. The two types of data strongly suggest that both small and large aggregates have a fractal structure, with well-defined fractal dimensions. If the system is aged long enough at low enough temperature, large asphalt particles will have the structure of diffusion-limited cluster-cluster aggregates with a fractal dimension Df ≃ 1.8, while the small ones are similar to diffusion-limited particle aggregates with a fractal dimension df ≃ 2.5. High temperatures increase the rotational motion of the particles, disturb the structure and mechanical stability of the aggregates, and decrease their fractal dimension. Aging and concentration effects of the asphalts in the solution, and the type of the solvent on the structure of the aggregates are also investigated. Implications of these results for the structure, mechanical stability, and molecular-weight distribution of asphalts and asphaltenes are detailed. A new molecular-weight distribution for asphalt aggregates predicts the experimental data excellently.
