uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
Phosphate and sulfate are essential macro-elements for plant growth and development, and deficiencies in these mineral elements alter many metabolic functions. Nutritional constraints are not restricted to macro-elements. Essential metals such as zinc and iron have their homeostasis strictly genetically controlled, and deficiency or excess of these micro-elements can generate major physiologica...
To investigate the relationship between mineral elements and plum gummosis disease, Prunus salicina Lindl. trees with four grades of were used as experimental materials. The contents N, P, K, Ca, Mg, B, Fe, Mn, Zn Cu in branches leaves measured, correlation was systemically analyzed through multiple comparisons, binary logistic regression analysis, ordinal analysis. In addition, effects prevent...
Background: Medicinal plants viz Tinospora cordifolia (Gulvel), Gymnema sylvester (Morasingi), Tricholepis glaberrima (Brahmdandi) are very important for treatment of diabetes mellitus and other various diseases. These plants have great importance due to their nutritive value and major source of medicines as they have been found through out human history Objective: Evaluation of Nutritive va...
The study of drying and wetting cycles in soils is important due to their effects on plant nutrition and soil fertility as well as environmental issues. Therefore, a laboratory experiment was set up with a completely randomized design and factorial arrangement in three replications to identify the influence of wetting and drying cycles in combination with or without application of organic acids...
while a crystalline material is heated from room temperature to around 500°c, a weak but measurable light will be emitted. this light is known as thermoluminescence (tl) and is based on storage of energy from ionizing radiation in many naturally occurring tl minerals, including quartz and feldspar. the source of radiation is the radioactive materials such as uranium, thorium, potassium and cosm...
The partitioning of reactive nitrogen compounds between the gas and the aerosol phase, as observed during the MINOS (Mediterranean INtensive Oxidant Study) campaign in Crete, Greece, in July and August 2001, has been studied with three thermodynamic gas-aerosol equilibrium models (EQMs) of different chemical complexity: ISORROPIA, which is limited to the ammonium-sulfatenitrate-sodium-chloride-...
mineral contents of camel meat were investigated during different periods of fattening. 12 camels (camelus dromedarius), at 12 months of age, were fattened with the same diet during six and nine month periods. feed compositions included 25% alfalfa, 25% straw and 50% concentrate (55% barley, 20% bran, 15% beet pulp, 8% cottonseed meal and 2% salt) were fed under the same conditions. completely ...
in this thesis, first the notion of weak mutual associativity (w.m.a.) and the necessary and sufficient condition for a $(l,gamma)$-associated hypersemigroup $(h, ast)$ derived from some family of $lesssim$-preordered semigroups to be a hypergroup, are given. second, by proving the fact that the concrete categories, semihypergroups and hypergroups have not free objects we will introduce t...
Leaf size indices of the tree species in the peatland of Agusan del Sur in Mindanao in Philippines was examined to deduce the variation of forest structure and observed forest zonation. Using raunkiaer and webb’s leaf size classification, the leaf morphometrics of seven tree species consistently found on the established sampling plots were determined. The species includes Ternstroemia phi...
