This article presents research and development of an interoperable platform to facilitate, monitor and coordinate groundwater data sharing. This system was orchestrated by a number of services described by Open Geospatial Consortium (OGC) such as Sensor Observation Service (SOS) and other services for the use of mapping data, Web Feature Services (WFS), Web Map Service (WMS), and catalogue services (CSW). An important activity for our project was the establishment of a portal for geographic data and services. Geoportal developed for this project will promote and facilitate access to groundwater data and share theme more openly. Otherwise our system has been designed to provide a powerful tool that enhances the ability of regional staff to monitor near real-time groundwater data (i.e.?piezometric level) and as a result will help provide a more effective response to environmental upsets.

Macular edema is one of the most common visionthreatening complications of uveitis noted in one third of patients with uveitis. The release of a number of inflammatory mediators induces retinal vascular hyperpermeability leading to uveitic macular edema(UME)which most commonly is of cystoid shape. Fluorescein angiography and non-invasive spectral-domain optical coherence tomography are standard procedures for diagnosis and follow-up of UME with some innovations such as scanning laser ophthalmoscope retro-mode imaging. Effective management of UME requires thorough understanding of the individual case. Proper control of intraocular inflammation is mandatory before targeting macular edema itself. Mainstay of treatment is immunosuppressive therapy with various drug delivery routes including topical, local subconjunctival, peribulbar and sub-Tenon's, intravitreal and systemic. Clinical trials with biologics are under way to study the efficacy of these agents in suppressing intraocular inflammation and resolution of UME. Visual prognosis in UME depends on numerous factors. Younger age and better visual acuity at baseline are associated with more favorable visual outcome in most

SCC (stress corrosion cracking) is environmentally well-known as a failure caused by exposure to a corroding while under a sustained tensile stress. SCC is most often rapid, unpredictable. Failure can occur in a short time as a few hours or take years and decades to happen. Most alloys are liable to SCC in one or more environments requiring careful consideration of alloy type in component design. In aqueous chloride environments austenitic stainless steels and many nickel based alloys are common to perform poorly. SCC of austenitic stainless steels of types 316 was investigated as a function of applied stress at room temperature in sodium chloride solutions using a constant load method. The experiment uses a spring loaded fixture type and is based on ASTM G49 for experiment method, and E292 for geometry of notched specimen. The stress depends on fracture appearance and parameters of time to cracking, and cracking growth. The results explained in terms of comparison between the two concentrations of sodium chloride solutions.

Objectives: To assess the impact of heart failure diseases on stroke severity and short term (1 month mortality). Materials and Methods: Totally, 200 patients admitted to Ain Shams university specialized hospital, were diagnosed clinically to have acute ischemic stroke within 3 days. History taking about previous heart disease was taken, and full general and neurological examinations were done. Full metabolic profile, cardiac examination and investigations were done. Carotid duplex, MRI stroke protocol and lastly clinical reevaluation using NIH Stroke Scale (NIHSS) after 1 month from stroke onset were done. Results: Patients with systolic dysfunction (EF ≤ 40%) had lacunar infarction in 18.75% of cases, partial anterior circulation infarction in 62.5% of cases, posterior circulation infarction in 6.25% of cases and total anterior circulation infarction in 12.5% of cases. Leucoaraiosis was present in 87% of cases and significant intracranial vessel stenosis was showed in 87.5% who had done MRI. Their median NIHSS score at admission was 10.5 with IQR of 5 - 21 and at follow-up it was 5 with IQR of 2.5 - 10.5. At follow-up 22.7% (5 patients) were dead. Conclusion: Systolic dysfunction (EF < 40) i.e. heart failure has no significant effect on stroke severity and 1 month follow up prognosis.
