Abstract A comprehensive workflow was developed to support short and long-term unconventional Midland and Delaware Basin development strategy. The workflow is applied to every new pad to ensure child wells are targeting more of the virgin rock. The developed workflow considers pressure and stress changes around parent wells, landing strategy, completion optimization, frac order design, etc. A 3-D reservoir model was developed to estimate the depletion and the induced stress changes around the parent wells. Hydraulic fracture modeling is coupled with the flow simulation model to assess child wells fracture propagation under different scenarios. Different landing strategies were investigated to reduce depletion effects on Child wells. Child wells fracture and proppant fluid intensity was optimized to provide the optimum fracture interference. Certain technologies were successfully utilized to change the pressure and stress around the existing wells to properly alter child well fracture propagation towards virgin rock. Frac order was adjusted accordingly to benefit from the induced changes in reservoir pressure and stress around parent wells. The workflow was applied to areas in the Wolfcamp formation within the Midland and Delaware Basins. Results show the effectiveness of the developed workflow to maintain Basin development performance.

At Alamán’s initiative a law of 1830 established the Banco de Avío, a government-funded development bank for the spurring of industrialization, especially in the textile sector, with which his name has forever been associated. His views of industrialization as a development strategy as opposed to a renewed reliance upon silver mining are discussed, as well as the short- and long-term effects of loans made to textile entrepreneurs and the cronyism employed by Alamán both in organizing the Banco itself and in allotting its capital as loans to industrialists. The state of the textile industry in Mexico before and after the Banco is described.

In spite of the great nutritive and pharmacological potentials of buckwheat, data about the abiotic stress tolerance of this plant species are very limited. The aim of this work was to analyze the biochemical and molecular response of buckwheat plants in the middle vegetative phase against short- and long-term salt stress. Changes in relative water content, level of lipid peroxidation, content and localization of H2O2 as well as changes in antioxidative enzyme activity and expression of ubiquitin and dehydrins, were investigated. Reasons for observed buckwheat salt stress sensitivity as well as possibilities for enhancing stress tolerance are discussed.

Egypt has many new areas, most of which are found outside the boundaries of urbanization in the valley and delta. Such areas contain capabilities and ingredients with special natural and environmental features that differ from the built-up areas. As development areas have been recently created by the development policies and strategies which were put forward by the country to accommodate sustainable development processes. There is an Availability of suitable areas for development according to resources and without limitations, which amount to 24% of the total area. There are, also, suitable areas for development according to resources with the presence of some limitations, which amount to an area of 16% of the total area. Sustainable development captures the world's attention during the past 15 years, at the level of the global economic, social and environmental field. Thus, development sustainability has become a global school of thought that spreads in most of the countries of the world, All UN member states adopted the Sustainable Development Goals in 2015 as the main umbrella for balancing social, economic, and environmental sustainability by 2030. And also the plans put forward in Egypt The research discusses what are the Requirements for reaching the sustainable goals of development to plan new areas in Arab Republic of Egypt. By using qualitative methods Because these areas have a shortage of statistical data. To can reach, foundations and indicators for sustainable development, adopting a national sustainable development strategy that includes all entities, institutions, members of society and those affected by its results in the short and long term.

Objective: Approximately one out of five patients with Graves' disease (GD) undergoes a thyroidectomy after a mean period of 18 months of medical treatment. This retrospective and non-randomized study from a teaching hospital compares short- and long-term results of total (TT) and subtotal thyroidectomies (ST) for this disease. Methods: From 1987 to 1997, 94 patients were operated for GD. Thirty-three patients underwent a TT (mostly since 1993) and 61 a ST (keeping 4 to 8 grams of thyroid tissue - mean 6 g). All patients had received propylthiouracil and/or neo-mercazole and were in a euthyroid state at the time of surgery; they also took potassium iodide (lugol) for ten days before surgery. Results: There were no deaths. Transient hypocalcemia (< 3 months) occurred in 32 patients (15 TT and 17 ST) and persistent hypocalcemia in 8 having had TT. Two patients developed transient recurrent laryngeal nerve palsy after ST (< 3 months). After a median follow-up period of seven years (1-15) with five patients lost to follow-up, 41 patients having had a ST are in a hypothyroid state (73%), thirteen are euthyroid (23%), and two suffered recurrent hyperthyroidism, requiring completion of thyroidectomy. All 33 patients having had TT - with follow-ups averaging two years (0.5-8) - are receiving thyroxin substitution. Conclusions: There were no instances of persistent recurrent laryngeal nerve palsy in either group, but persistent hypoparathyroidism occurred more frequently after TT. Long after ST, hypothyroidism developed in nearly three of four cases, whereas euthyroidy was maintained in only one-fourth; recurrent hyperthyroidy was rare.
