Secondary outcome measures encompass the success of biliary drainage, quality of life, and postoperative morbidity and mortality.
The aim of this study is to compare EBD and PTBD in terms of the total number of preoperative severe drainage-related complications (primary outcome), the success of biliary drainage, quality of life, and postoperative morbidity and mortality.
To increase the drainage quality of a potting soil, add sand, grit or charcoal.
The model can be used to design denitrification beds with efficient nitrate removal which in turn leads to enhanced drainage water quality.
The results indicate that combined use of FA and SS at a rational rate of application should not cause any significant effect on drainage water quality.
The greening component of direct payments aims at supporting environmental commitments throughout the EU, by means of introducing additional payments for public goods (e.g., subtraction of CO2, soil protection, water drainage and quality).
Also under drained conditions (Sampla, Haryana, India), a close agreement was obtained between the measured data and simulated values of water table depth, drain discharge, soil salinity and drainage effluent quality.
The Chinese authors of the current paper were involved in the project, which intends to establish a daily monitoring system for the wetland park which includes specific measures such as a wetland ecological monitoring project, publicity and education, wetland drainage, water quality restoration, and wetland management.
Since the model is a recent addition to the literature, it would be appropriate that more evaluation studies are undertaken before concrete recommendations are made in regard to its applicability to simulate leaching and drainage effluent quality (salt transport) in drained lands.
As agriculture in the 21st century is faced with increasing pressure to reduce negative environmental impacts while continuing to efficiently produce food, fiber, and fuel, it becomes ever more important to reflect upon more than half a century of drainage water quality research to identify paths forward.
Variables were initially screened within major subsets: ventilation; roof and floor drainage; building quality, materials and repair; house structure; pest proofing; biosecurity; sanitation; and house size.
