Seizing the main contradiction of fast water-bearing rebound in western block III, analyzing reasons response to contradiction, meanwhile, by understanding mechanism polymer oil drive and combining development effect three injection gathering blocks, finding out that problem slowing down is establishment pressure system, therefore corresponding management measures at extraction ends respectively.

The AlGaInP window layers with different growth modes of Al in (AlxGa1−x)0.5In0.5P were prepared to investigate the effect on photoelectric properties red LEDs. experimental results show that forward voltage LEDs n-window layer ridge gradient content was 30 mV (x = 0.15) and 190 0.45), respectively, which are lower than without samples. Meanwhile, light output power LED is 12.3% 3.6% 0.45) high...

introduction: one of the basic problems of hospital management is lack of an effective fiscal system, which causes in loose cost control. meanwhile, accounting techniques and economic analyses may help the managers to decide better in planning programs and investing fields. then, it’s time to have a better estimate of health care services costs in our competitive situation for the hospitals, in...

In this study, we measured the level of ferrum ion and VEGF from the hematoma cavity fluid in chronic subdural hematoma (CSDH), and analyzed the relationship between these values with the CSDH diagnosis by MRI. The cranial MRI appearance of each CSDH were classified as hypodense, isodense, hyperdense, or mixed density. The concentrations of ferrum ions in serum and hematoma cavity fluid were me...
