Multistage hydraulic fracturing has become one of the most important techniques in the successful exploitation and development of shale or unconventional reservoirs. Most of the unconventional reservoirs like coal bed methane, shale gas, shale oil, tight gas and tight oil reservoirs rely heavily on the multistage hydraulic fracturing technique for commercial success, feasibility and viability.The ultimate goal in unconventional or shale gas reservoir is to contact as much as possible with a hydraulic fracture or a hydraulic fracture network of optimal fracture conductivity. This ultimate goal is accomplished by horizontal well drilling of appropriate length with creation of traverse multi fracture stages by hydraulic fracturing process. Shale gas reservoir contact with the horizontal well bore is optimized by defining the optimal length of horizontal well, optimal fracturing fluid volume with optimal mass of proppant, number of multi frac stages to be placed in horizontal lateral of well and fracture spacings or isolation between fracture stages. Optimal fracturing fluid volume and mass of proppant depend on the optimal fracture lengths and optimal fracture conductivities of each fracturing stage.Multistage fracturing and long length horizontal wells increase the cost of shale gas field development as compared to conventional field development. The economics of shale gas field development can be improved significantly by using global optimization algorithms to find the maximum Net Present value. In shale gas reservoirs the parameters of hydraulic fracturing like fracture half length, amount of proppant with desired fracture conductivity, fracture Patterns, number of fracturing stages and fracture spacing should be optimized in order to maximize the profit or Net Present Value.In this work, stochastic optimization is implemented in order to maximize the profit in terms of Net Present Value by optimizing hydraulic fracturing parameters and horizontal well length. In the optimizations considered here, global optimization algorithm, Differential Evolution is applied and seek to determine the optimal fracture lengths, fracture spacings, number of fracture stages, fracture conductivities and horizontal well length.Stochastic optimization successfully implemented in more realistic LGR based gas shale reservoir simulation model by coupling with global optimization algorithm. Net present value is maximized for three different cases by finding global optimum solution for the multistage hydraulic fractures parameters and horizontal well using Differential Evolution algorithm. The comparison of the automated optimization results with base case indicates that the significant profit increase observed by using coupled Differential Evolution algorithm. This work can be significant valued addition for oil and gas industry, because by using these computational algorithms, workflows and framework, they can maximize Profits in terms of Net Present value from shale gas reservoirs.

Les observations du nombre de taches solaires ssn portent sur près de trois si cles, soient 22 cycles « undecennaux ». Dans chaque cycle, l'activité solaire passe par un minimum et un maximum. L'occurrence de ces extrema est un phénomène chaotique. L'activité géomagnétique suit, à l'intérieur du cycle, l'activité solaire. La distribution sur près de deux siècles de l'indice aa de l'activité magnétique nous permet de montrer une importante corrélation entre l'état du Soleil et le champ magnétique terrestre. Cette étude basée sur l'analyse spectrale (Fourier, Ondelettes) de données synthétiques et réelles confirme d'une part l'existence de composantes harmoniques des variations du champ magnétique terrestre (T=24h, T=27jours, ... ) et montre par ailleurs la présence de singularités non déterministes. Ces variations sont étroitement couplées aux variations de l'activité solaire. Les résultats trouvés sont encourageants et méritent d'être complétés par une étude planétaire et l'apport d'autres données (valeurs moyennes minutes du champ magnétique terrestre fournis par le réseau d'observatoires INTERMAGNET, satellite SOHO, etc....) et approfondis par une meilleure compréhension du Soleil et des phénomènes physiques qui régissent son activité.

Breast cancer is the malignant tumor that forms from the uncontrolled growth of abnormal breast cells. It usually affects tissues involved in milk production (Ductal and lobular tissues). It is the most common malignancy in women and itremains one of the greatest health threats facing women around the world as we enter the 21st century. The total number of breast cancer patients involved in this study were (80) individual taken from Basrah oncology center in Basrah province, The age of patients range from 27-76 years and (80) individuals considered as control group after they were checked and confirmed to be free from any chest or any other health problems , The data of all patients were used to built a general classification model for breast cancer. The system offer an effect summary that examine each demographic factors that have an importance across multiple responses. The study showed the minimum number of breast cancer patients was found amongthe age groups 20-29 years (2.5%),followed by age group 30-39 years (12.5% ,above 40-49years (31.25%), the age group 50-59 years (32.5%) and >60 years (21.25%). P-value <0.0163.The residence of patients with breast cancer was found in central 45 (56.25%), followed by in peripheral 35 (43.75%), with P-value = 0.1008. The effects of various demographical factors effecting patients with breast cancerstarted with various marritalstatus that show the number of Singlepatients 3(3.75%), followed by married 71(88.75%) and divorced 6 (7.5), Theclinical features, that patients using surgery was 72(90.0%) and who do not the surgery 8(10.0%), Then comes the other factor the Chemotherapy, the patients with breast cancer who take the chemo therapy 77(96.25%) and who donot take chemotherapy 3 (3.75%) with P = 0.089, and the last factor metastasis the patients who have metastasis 23 (28.75%) and the patients not have 57 (71.25%). There were significant differences between BMI of patients with breast cancer (P=0.01), and show the majority of patients belong to overweight group 36 (45.0%) followed by obese patients 14(17.5%) (P-value = 0.0150). The data was recorded in stages of the breast cancer which notice the Stage of IIA was (25.00%) appeared in 22 breast cancer patient, followed by stage IIB was (23.86%), stages IA and IIIC were 2(2.27%) for each, and they are followed by stage IB 1(1.14%) , stage IIIA 19(21.59%), stage IIIB 3(3.41%) and stage IV 10 (11.36%) there were significant difference (P<0.001).The levels of interleukin IL-1βpg/ml among patients with breast cancer and control groups in various age group that show the age group (20-29) years (2.87 pg/ml) followed by (30-39) years (3.485 pg/ml) , continued with (40-49) years (4.168 pg/ml) , (50-59) years (4.733 pg/ml) and ( >60) years (5.049 pg/ml) with P-value = 0.03669 .The levels of interleukin IL-6 Pg/ml among patients with breast cancer and control groups in various age group that show the age group (20-29) years (4.69pg/ml) followed by (30-39) years (4.97 pg/ml) , continued with (40-49) years (6.30 pg/ml) , (50-59) years (6.28 pg/ml) and ( >60) years (6.65 pg/ml) with P-value = 0.01599.The levels of interleukin IL-10 pg/ml among patients with breast cancer and control groups in various age group show the age group (20-29) years recorded (2.18 pg/ml) followed by (30-39) years (22.15 pg/ml) , continued with (40-49) years (24.16 pg/ml) , (50-59) years (26.33 pg/ml) and ( >60) years (26.87 pg/ml) with P-value= 0.0042.

Patient safety is an area of healthcare that has emerged with the increasing complexity of healthcare systems and the rise of harm to patients it is about preventing and reducing risks, errors and harm to patients in the context of health care. Patient safety is first and foremost about continuous improvement, through learning from errors and adverse events. In this context, the health sector must achieve the conditions for the protection of patients throughout the duration of treatment, taking into account the situation of each patient separately. Among the conditions of protection of our patients, the writing of a good appropriate prescription which does not lead to undesirable effects. And given the presence of several factors that can give undesirable and sometimes fatal results and effects to our patients following the wrong prescription. It has become necessary to take this area seriously by improving the editorial quality of medical prescriptions.
