To promote the use of poor quality water for irrigation, a field research study was conducted in three semi-arid regions with water scarceness in Syria in order to define, under field conditions, the wheat yield response function to irrigation water salinity, the effect of soil texture and structural characteristics on the irrigation water salinity threshold, and to compare this value with the conventional threshold value. 

The results of this research study indicate that wheat tolerance for irrigation with saline water is affected by various real in-field conditions, including soil texture and structure, climate, irrigation water management and agricultural practices. 

The properties of the materials were evaluated by textural and structural techniques, while the final catalysts are compared on the basis of their N20-decomposition under simulated industrial conditions for nitric acid plants. This reaction is known to be activated by Fe-species [151, 152].

Petrologic and SEM analyses of these clay samples reveal micro-textural and structural features and mineral association suggesting that they deposited directly from the brine in the surface facilities, and are not hydrothermal alteration minerals transported from production wells.

Texture and structure are not explicitly defined terms. Structure is usually applied to macroscopic heterogeneity due to macroscopic movement such as flow structure or foliated structure, whereas texture usually refers to microscopic heterogeneity, such as holocrystalline texture, porphyritic texture, and lamellar texture due to exsolution. 

In this section, we shall analyze the factors controlling the formation of the texture and structure of polycrystalline aggregates of multiple phases seen in... 

The shells of bivalves consist of periostracum, consisting of hard protein tissue, and ostracum, consisting of CaC03, which is further divided into outer, middle, and inner shell layers. The shell structure of bivalves is classified into the following seven layers based on the textures and structures. 

We shall first examine the microscopic techniques which allowed us to study these transformations and to show the striking analogy between the images obtained by optical microscopy in polarized light and by electron microscopy with ultrathin sections, despite the difference of the absorption mechanisms of light and electrons. Once this analogy was established, we sought to use electron microscopy and electron microdiffraction to learn more about the texture and structure of the anisotropic areas.

The texture and structure of foods is very delicate, therefore experimental methods which cause no or vety little structural damage has to be applied in their investigations. Such techniques, the surface force balance and back-light scattering methods and dielectrometry will be also discussed in the chapter.

Compared to conventional white-light analysis, fluorescence microscopy reveals a greater number and variety of macerals, as well as, characteristic textures and structures. Although the spectra of fluorescent macerals are broad-peaked and, at this time, not suitable for chemical structure analysis, they are characteristic of maceral types and rank. 

Sampling. Two sets of vibracores were collected at each site. A previously collected set was used, along with other cores in each area, to determine stratigraphic and sedimentologic relationships. Color, texture, and structure were used to establish different lithofacies, which were later verified or modified using x-ray radiography. Ash and total sulfur contents were then determined for channel samples of these units. 

Changes in soil consistence are a useful surrogate measure for identifying restrictive layers because soil texture and structure are often difficult to measure consistently by inexperienced operators and because root abun-... 

Like polysaccharides, proteins impart texture and structure to foods. Protein-polysaccharide blends may assume physical, ionic, or covalent character, may be soluble or insoluble, and may sometimes exhibit synergism. The characteristics of the blend are as much a response to the reaction environment as to the properties of each ligand. 

Abstract. The transition from a variety of scientific bases of preparation of porous materials (adsorbents, catalysts, etc.) to a uniform fundamental knowledge is discussed. This transition is based on allocation of two different but general levels of porous materials science molecular (atomic) and supramolecular (textural). Fundamental relationships and laws are discussed in the application of porous materials for catalysis and adsorbents with respect to texture and structure.
