BACKGROUND Chemotherapy-induced neutropenia is a common adverse effect in children with cancer. Due to the high relative risk of infections and infectious complications, standard care for children with cancer and febrile neutropenia consists of routine hospitalization and parenteral administration of broad-spectrum antibiotics. However, there are less serious causes of febrile neutropenia; in a...

Background and Objectives: Discharge against medical advice (DAMA) is a significant healthcare problem posing negative impact on effectiveness of patient care and costs of the health system. In order to address this problem, first the potential influencing factor should be identifies. This study followed two major objectives: first, to evaluate the prevalence and potential causes of DAMA, and s...

Establishment of rating curves are often required by the hydrologists for flow estimates in the streams, rivers etc. Measurement of discharge in a river is a time-consuming, expensive, and difficult process and the conventional approach of regression analysis of stage-discharge relation does not provide encouraging results especially during the floods.

In this study, needle-array to plate electrode configuration was employed to generate an atmospheric air diffuse discharge using both nanosecond pulse and sine AC voltage as excitation voltage for the purpose of improving indoor air quality. Different types of voltage sources and electrode configurations are employed to optimize electrical field distribution and improve discharge stability. Dis...

Side weirs are flow diversion devices that are widely used in irrigation, drainage and urban sewage systems. The present study focuses on the investigation of the effect of oblique side weirs on the discharge coefficient of a side weir under subcritical flow condition in rectangular channels. In this study 106 laboratory tests were conducted and the results were analyzed to find out the influen...

Flow-rate measurement in rivers under different conditions is required for river management purposes including water resources planning, pollution prevention, and flood control. This study proposed a new discharge estimation method by using a mean velocity derived from a 2D velocity distribution formula based on Tsallis entropy concept. This procedure is done based on several factors which refl...
