Commodity prices based on the value of goods and the supply and demand, the stock can be used as something of a similar products, it has two functions of the existence of commodity, but it is not completely equal to have the function of the goods. This kind of goods and other commodities are very different, its internal price is based on the issuance of company value rather than the value of stocks. According to the definition of goods, goods should have value and use value, and the value of the goods is by producing goods of the general labor decided there was no difference in the amount of. But stock is not like that, the basis of its value due to the exchange, not as a stock itself has value and use value, determinant is not production it takes general labor time, not because of itself as a commodity supply and demand, but it represents the value and potential of the economic entity and market investors to represent economic entity of interest and the view of future growth (use value), the value of the entity and potential may be expressed through the stock. In exchange for not stock the use value of goods itself, but the stock represented by the value of this commodity variability and the infinite space to grow up for a long time, thus has particularity. So is the price of the stock, but as a special commodity, stocks in price decision factors also has particularity. This article is from the value and supply and demand to discuss the particularity of stock pricing.

Naturally occurring radionuclides such as uranium, thorium and their decay products (226Ra, 222Rn) are present in a number of geological settings in Basrah Governorates. The uranium concentration of 78 soil samples using ICP-Mass (inductively coupled plasma mass spectrometry) was found to be ranging from 1.2 ppm in Eastern star1 to 15.75 ppm in AL-Liheise10 in soils. The results are presented and compared with other studies . The measurements of uranium concentration of soils samples measured had a uranium content of less than 100 ppm, a concentration that characterizes overburden and tailings quality, rather than minable reserves. This paper presents and evaluates the concentration of uranium in Basrah Governorates .The study further reveals that 78 surface soil samples have uranium below detection limit.

The H reservoir in W oilfield belongs to delta front deposition and it is formed by the impact of both geological forces of the rivers and waves. The reservoir is strongly transformed in the later stage. Therefore, it formed the scattered sand body, obvious heterogeneity, complex fluid distribution, causing that the original parameter interpretation method can not accurately characterize the regularity of the target area. For this problem, this paper use original data of drill core, well logging and oil testing as base, doing the research of curve standardization, principal component analysis and parameter optimization in target area, respectively established porosity interpretation model which based on muddy correction, compaction correction and sedimentary facies correction and permeability interpretation model which based on the type of sedimentary facies, summarizing the physical characteristics and the conclusion is drawn that the target area is low porosity and ultra-low permeabilite reservoir characteristics. Therefore, this paper not only provides the basis for the development of target area, but also provides an effective method for the interpretation of the physical parameters of complex reservoirs.
