This paper addresses the factors responsible for changes in crude oil prices, in real market and financial sector. In order to prepare the analytical background for further investigation, it highlights the patterns of correlations of the real oil price and the most related prices of assets, exchange rate and government bond yield. The paper reviews the statistical behavior of oil price, quantities and the global macroeconomic environment. Topics discussed include the theory of differential rent and scarcity effect ,the role of future market and speculation, strategies of energy of the major economies to investigate the prospects of oil market and the potential demand for OPEC's oil. The paper explores the interrelationship between spot and future prices using daily data , explanatory power of real effective exchange rate in addition to conventional demand and supply functions. Although, The paper finds regularities consistent with the predictions of economic theory, it concludes that the changes in real price of oil have historically tended to be difficult to predict. Further research works are recommended particularly in the areas of storage arbitrage and financial future contracts.
A local isolate Bacillus subtilis was used, which producing

Show MoreCorrosion behavior of aluminium in 0.6 mol. dm-3 NaCL solution in acidic medium ( ) was investigated in the absence and presence of different concentrations of amino acid, glutamic acid, as environmentally – friendly corrosion inhibitor over temperature range (293-308)K. The investigation involved electrochemical polarization method using potentiostatic technique and optical microscopy, the inhibition efficiency increased with an increase in inhibitor concentration but decreased with increase in temperature. Results showed that the inhibition occurs through adsorption of the inhibitor molecules on the metal surface and it was found to obey Langmuir adsorption isotherm. Some thermodynamic paramet

The aim of the present study was to investigate whether safranal, an active constituent of Crocus sativus L. stigmas, has a protective effect on the cataract in the rat's pups. The animals were randomly divided into five groups, each of which consisted of 7 rat pups. Group I served as normal control (vehicle administration). For testing cataract induction, animals of Groups II, III, and IV were administered a single subcutaneous injection of sodium selenite on postpartum day 12. After sodium selenite intoxicatio

Emitters dissipate energy of water at the end of the trickle irrigation system and provide water at emission points. The area wetted by an emitter depends upon the discharge of emitter, soil texture, initial soil water content, and soil permeability. The objectives of this research were to predict water distribution profiles through different soils for different conditions and quantify the distribution profiles in terms of main characteristics of soil and emitter. The wetting patterns were simulated at the end of each hour for a total time of application of 12 hrs, emitter disch

Hyperandrogenism is the major standard in the diagnosisof PCOS development.Eighty women diagnosed with PCOS and twenty healthy women(aged 20-40 years)were enrolled in this study which was conducted at the infertility clinic of Kamal AL-Samaraay Hospital/ Baghdad. The diagnosis of PCOS was made according to the Rotterdam criteria. Body mass index (BMI, Kg/m2)was calculated by a specific formula. History of menstrual irregularity, hirsutism, acne, and alopecia was taken. Hormone levels in serum, namely luteinizing hormone (LH), follicle stimulating hormone (FSH), and testosterone were measured in all patients and control subjects.There was a statistically si

The variation of HSP70 activation occurs as a consequence of stress that includes temperature states, toxicity, poisoning with heavy metals, and tumor-related conditions. One of the master jobs of the HSP family is the suppression of caspase-mediated apoptosis signals. A high level of the expression of HSP70 is accountable for tumorigenesis and resistance against chemotherapeutic drugs. For this reason, the detection of HSP70 may help to diagnose cancerous diseases. From the other side, targeting this chaperone might help in treatment by maintaining late caspase-dependent events. This study was conducted to detect the presenc

The prodrug Irinotecan is converted by carboxylesterase to the active metabolite SN-38, conjugated by UGT enzyme to SN-38G and then deconjugated by ?-glucoronidase produced by intestinal bacterial flora to produce SN-38. Irinotecan induces intestinal mucositis and diarrhea due to increased concentration of its active metabolite (SN-38).To evaluate the protective effect of carvone, I.P injection of (75mg/kg/day) of irinotecan for 4 days to induce intestinal mucositis, carvone administered to mice orally for 6 days starting from day 1. Results showed that carvone (50mg
