Oil or petrol is considered a conventional natural resource that must be protected from any damage, as it forms the key of the national income and the fundamental base for the Iraqi economy which is called the nerve of life & black gold. Due to the American invasion which destroyed the infrastructure in Iraq by military forces, then the second page came through terrorism which last for more than 3 years to destroy the rest of the national economy, by burning the oil wells in Qayyarah region in Nineveh province. The terrorists have set 19 oil wells on fire out of 63 in May 2016. The burning of Qayyarah area oil fields south of Mosul city caused huge gaseous emissions such as carbon dioxide, Sulfur oxides, Nitrogen oxides, Organic compounds, carbon monoxide, particulate matter, methane etc. The above operations produced negative effects on sustainable development factors; Ecologically, Economically, and Socially. Ecologically; effects on atmosphere were very obvious by means of intensive smoke, sunlight curtain, shading, acid rains, temperature raising, prevention of cloud condensation, disruption of air components, increasing toxic elements in the atmosphere by increasing the proportion of carbon dioxide and carbon monoxide, and their influence on soil elements balance status, negative effects on soil microorganisms, influence on bio-processes between the producer, consumer and decomposer in energy flow, lowering land productivity, desertification, plant death and the influence on biological and physical, and chemical traits of water resources. Toxicity and suffocation were also common in the area of burning as a result of the movement of smoke clouds. Economically, biodiversity loss, oil production stoppage, seed germination failure in the exposed lands to military operations which reduced the yield, and general effects on the agricultural and livestock sectors which caused a big loss in the national economy. Then the rehabilitation of all these damages surely will cost a lot of money and effort to get rid of these wastes. Socially, the oil wells combustion caused human troubles such as poverty, death, immigration of farmers from their land, joblessness, education stoppage, various diseases such as cancer, asthma etc.Keywords: Oil Burning, Qayyarah, Technogenic impact, Sustainable development, Nineveh, Iraq.
Secret Sharing is a robust key management method in which shares are distributed to parties and only authorized subsets of parties can reconstruct the secret. Secret sharing schemes are the tool used in cryptography and security. There are different methods of secret sharing. Threshold secret sharing is a method in which out of all the parties only predefined or certain number of parties can reconstruct the secret. In this paper we will describe a threshold secret sharing scheme, the Shamir’s secret sharing scheme and proposing an alternative approach for secret recovery instead of Lagrange interpolation over finite field. Based on this study we can use it in different applications such as secret data hiding and authentication, audio secret management, medical image security and EPR hiding, in storing credit card information securely.Keywords: Credit card, Secret sharing, Security, Shamir’s secret sharing, Threshold secret sharing.
In this study, the mass absorption coefficient (?/?), half-value thickness (HVL), one-tenth thickness (TVL), mean free path (?) values ??were calculated of some shape memory alloys at 5.9-6.1-8-11.2-25-59.543-75-112-149 keV energy. It has been observed that the obtained values ??of the calculated parameters vary depending on the photon intensity, chemical constitution and density of the alloys. Calculations were made using the WinXCOM program and the graph of the change according to the energy of the obtained results was drawn. The results of this study are thought to be beneficial in the application of various fields.Keywords: Half-value thickness, Mass absorption coefficient, Mean free path.
