denitrification of high- nitrate high- salinity wastewater is difficult due to plasmolysis and inactivation of denitrifiers at high salinity conditions. in this study, the effects of salinity and empty bed contact time (ebct) on simultaneous heterotrophic and sulfur based autotrophic denitrification of synthetic wastewater were evaluated in an up flow packed bed reactor .the reactor was filled ...

lysimeter tests were conducted on shallow groundwater that supplies part of the maize water requirements to determine crop yield. twenty-four 0.8 m diameter lysimeters were buried in the test field at a depth of 1.2 m. the lysimeters were filled with the field soil (silty loam) and planted with summer maize. the groundwater depth in the lysimeters was set at 0.6 m using marriotte bottles. three...

cor triatriatum is an acyanotic congenital heart disease. we present a rare case of cor triatriatum sinistrum in a 6-month-old female infant who was presented with cyanosis and failure to thrive. the 2d transthoracic echocardiography and the doppler color flow imaging showed a proximal venous chamber communicating to the distal left atrium  through restrictive opening to the low-pressure, dista...
