Effects of Wetland Conversion to Farming on Water Quality and Sediment and Nutrient Retention in a Tropical Catchment - Abias Uwimana - Bog - Taylor &

Effects of Wetland Conversion to Farming on Water Quality and Sediment and Nutrient Retention in a Tropical Catchment - Abias Uwimana - Bog - Taylor &

The study used a combination of landscape-scale synoptic surveys (catchment, reaches) and mesocosm surveys (experimental plots) to assess the impacts of conversion of natural valley-bottom wetlands to farming land on the water quality and retention of sediment and nutrients. The results showed that temperature, pH, electrical conductivity and dissolved oxygen concentration decreased, and total suspended solids (TSS) increased with storm water increase. Nitrogen (TN) and phosphorus (TP) accumulated in the catchment during the dry season and washed into the water courses during the early stages of the higher flows, with subsequent lower concentrations at the end of the rains due to dilution. Large proportions of the annual loads of TSS, TP and TN (93%, 60% and 67%, respectively) were transported during rainfall events that occurred in 115 days. Fishponds acted as temporal traps of TSS, TN and TP at the early stages of farming, and were a source of and TN and TP at the end of the farming period, in contrast to rice farming that generated sediments and nutrients early in the farming period and trapped them at the end of the farming season. Wetlands mostly acted as sinks but sometimes as a source of sediment and nutrients.

Analysis of Grounding and Bonding Systems - Massimo Mitolo - Bog - Taylor & Francis Ltd - Plusbog.dk

Analysis of Grounding and Bonding Systems - Massimo Mitolo - Bog - Taylor & Francis Ltd - Plusbog.dk

Learn the theory behind grounding systems and bonding equipotential connections from a worldwide expert. Through mathematical analysis, comprehensive explanations, and detailed figures, Analysis of Grounding and Bonding Systems explains the theory and the reasons behind basic ground-electrodes (i.e., the sphere, the ground rod, and the horizontal ground wire), and more complex grounding systems (i.e., ground-grids), buried in uniform and non-uniform soils. Through calculations and explanatory diagrams, this comprehensive guide provides code-complying solutions for the safety against electric shock provided by equipotential bonding connections between exposed-conductive-parts, such as equipment enclosures, and metalwork. Details on the calculation of step and touch voltages in different types of system grounding (i.e., TT, TN, and IT) are provided, also with the aid of solved problems. Readers will learn how to minimize hazardous interactions between grounding systems, cathodically protected pipelines, and heat networks. The analysis of the effectiveness of bonding systems against electric shock in the case of contact with electric vehicles during charge in the event of ground-faults, which is an upcoming issue challenging our safety, is included.

Leadership in the U.S. Senate - - Bog - Taylor & Francis Ltd - Plusbog.dk

Leadership in the U.S. Senate - - Bog - Taylor & Francis Ltd - Plusbog.dk

Unlike leadership in the House of Representatives, the nature of Senate leadership continues to remain a mystery to so many. Due to the absence of an "operator’s manual," leaders have had to use their individual skills, intelligence, and personalities to lead the Senate, which means they each have had their own unique leadership style. How have Senate majority leaders advanced their agendas in this traditionally egalitarian institution, a chamber like no other legislative body, where they must balance the rights of 99 independent senators with the collective needs of their party? Featuring a foreword by Senate Majority Leader Mitch McConnell, Leadership in the U.S. Senate offers students a comprehensive and contemporary examination of three different eras in the evolution of the Senate. Collectively, contributions written by those who have served the senators offer insight into how different Senate leaders have operated, chronicle changes in Senate life over the past four decades, and describe how they have changed the institution. The chapters cover: - - How leadership styles are shaped by both individualism and party goals - - - Eight biographical perspectives from Senator Howard Baker (R-TN) to Senator Harry Reid (D-NV) - - - The political context of the Senate during which the respective majority leader served - - - Individual leadership style and performance in office - - - Contributions individuals made to the institution while serving as majority leaders - This book paves the way for political scientists and others to examine the topic of Senate leadership.
