یک فضای خطی متناهی بر v نقطه با b خط یک فضا است که در آن از هر دو نقطه درست یک خط عبور می کند. در این پایان نامه ما مقالات زیر را که مربوط به فضاهای خطی ایت را بررسی می کنیم. melone, n. (1991). a structure theorem for finite linear spaces. lecture notes math, 2, 231-241. bridges, w.g. (1972). near 1-designs. j. combinatorial theory (a), 13, 116-126. varga, l.e. (1985). a note on the structu...

Knowledge of the spatial dependency of soil properties, sensitive to grazing systems, is important from an ecosystem protection point of view. In the current study, geostatistical methods and fractal concepts have been used in order to characterize the impact of long-term grazing exclusion on the spatial variability of some soil chemical parameters including organic matter, total nitrogen, avai...

High Energy Density Materials (HEDMs) are a new generation of high-energetic materials with high-performance and safety and consist of several different types with different properties. One category of this kind of HEDMs explosives are high energy metal organic frameworks (HE-MOFs) that have more appropriate performance and safety compared to conventional explosives (HEMs) and even other HEDMs....

Organic components associated with diatom cell wall silica are important for the formation, integrity, and function of the cell wall. Polysaccharides are associated with the silica, however their localization, structure, and function remain poorly understood. We used imaging and biochemical approaches to describe in detail characteristics of insoluble organic components associated with the cell...

Biological activity of drugs and other organic compounds is determined by their solubilities in water or any other solvent or solution. Several methodologies to compute the solubilities of organic compounds have been devised, however most of them are bound to aqueous solutions, and many times the methodology works for a limited number of compounds. Furthermore, those methodologies state very li...

Crystallographic data analyses indicate that  three types of prolinium cations, along with two types of hydrogen  bonding,  produce and stabilize the helical structure of  triprolinium 12-phosphomolybdate. There are similarities between this organic-inorganic compound and peptides/proteins. The stronger “conventional” hydrogen bonds and the less common C-H…O attractions play critical roles in g...
