Year after year, the impacts of climate change become more destructive. Accordingly, finding the appropriate solutions to adapt with such impacts begins to be a constant concern of many cities worldwide. In this field, urban green infrastructure or (UGI) provides appropriate solutions for different climate change impacts such as floods, urban heat island, pollution, drought, water scarcity, soil erosion, energy deficit, etc. Literature review indicates a limited knowledge about UGI planning strategies as climate change adaptation (CCA) in existing cities. Accordingly, the current research seeks to extract these strategies from the real world practices of UGI. The applied methodology is known as 'learning by doing'. Many eminent practices of UGI planning in existing cities for the purposes of CCA are selected. A cross analysis is conducted between them to extract their common UGI strategies. The research's results reveal that the explored practices almost depend on similar strategies which based on injecting the natural green and blue assets into the exiting urban land usessuch as streets, parking, public buildings, etc. This strategy can be called "urban green injection". So, the opportunity to have UGI in the crowded cities depends on the innovative investment of the public land uses and converting them to vegetated or water-covered assets. Following such a strategy can ensure the alteration of the city image from the traditional natural-lacking character to a more sustainable and vibrant one. Adopting urban green injection can also ensure the maximum possible benefit of UGI employing as it was extracted from the successful outcomes of other practices.

In this paper an approach of computer design, simulation and implementation of multi switched mode power supplies (SMPS) controlled by one microprocessor is investigated. The design of three switch mode power supplies based on flyback DC-DC converters with different power 20,24 and 6 Watt and output voltages rated +5V,+12V/ and -12V are achieved. The design power stage is based on the bipolar as the main switching device with protection network used to ensure safe operation. The microprocessor and its supervisory board are used with slight software program to control the output of the multi switched mode power supplies (SMPS ) even though they have different switching frequency, output voltage, output power. The system performance is simulated and examined under many desired conditions. From the obtained result it was found that, it is efficiently and easily to use one microprocessor to control of multi switched mode power supplies reducing the complexity of the system

Water saturation is calculated by many models that developed over the years based on known physical principles or on empirically derived relationships. The accurate determination of water saturation in complex carbonate reservoirs is the most challenging aspects of well log analysis. The complex formation under study is Mishrif carbonate formation which is one of the deepest hydrocarbons bearing zone in the Nasiriya oilfield in south of Iraq. The available scanned copes of well logs are digitalized by using Neurolog software. Schlumberger charts 2005 had been used for environmental corrections. These correction charts are supplied in the Interactive Petrophysics software. Simple Archie equation, Dual water model, and Indonesia model have been used to calculate water saturation of Mishrif carbonate formations. After making the environmental corrections, the porosity interpretation shows that the logging tools have a good quality of data reading. From Indonesian model, the water saturation for Mishrif formation is ranged from 0.25 to 0.41. This study is provided water saturation values with depth that should use to calculate original oil in place and detect the perforation zones in the pay zone using Interactive Petrophysics software.

The Percentage errors in depth estimation from magnetic anomalies due to dyke-like bodies, having various depths and inclination angles, are calculated. Two methods have been used to estimate the depth of these bodies and then their percentage errors in depth estimation are compared. These methods are the well-known slope-half slope method and the method adopting procedure through using Fraser filter. The two methods have accompanied various percent errors in depth estimation for models having various magnetic parameters. The comparison between the calculated error values obtained from the two methods show that the differences between the maximum and minimum percent error with various inclination angles and depths are smaller for depths estimated by using Fraser filter procedure. Such results highlight the lesser mistakes that can be achieved if the procedure of depth estimation using Fraser filter is considered and in addition, the ease of the application of this procedure compared with slope method.
