Root-knot nematodes suppress yields of flue-cured tobacco an estimated 0.1 to 4.8% annually in the southeastern United States, even though nematode management practices have been widely adopted. Although Meloidogyne incognita races 1 and 3 have predominated, M. arenaria, M. javanica, and M. incognita races 2 and 4 are increasingly important. Seventy-five percent of the flue-cured tobacco hectar...

Understanding the speciation of mercury throughout the coal-combustion process is crucial to the design of efficient and effective mercury removal technologies. Mercury oxidation takes place through combined homogeneous (i.e., strictly in the gas phase) and heterogeneous (i.e., gas–surface interactions) pathways. Both bench-scale combustion experiments [1] and quantumchemistry-based theoretical...

Pipelines, wellbores and ground installations are permanently controlled by sensors spread across the crucial points in the whole area. One of the most popular techniques to support proper oil drive in a wellbore is a Gas Lift. In this paper we present the concept of using wireless sensor network (WSN) in the oil and gas industry installations. Assuming that Gas Lift Valves (GLVs) in a wellbore...

one of the most important practices in flue-cured tobacco farming is topping and sucker control at the right time. topping cause's development and root growth, drought tolerance, reduce deployment pests, increased synthesis of nicotine. this study was conducted in randomized complete block design (rcbd) with 10 treatments in 3 replications over two years (2008-2009) at tirtash research and educ...

the paper introducedeffects of modified pyrolysis tar on flue gas desulfurization. this experiment selected the pyrolysis tar as the raw material, researched the effects on desulfurization performance under different modification solution, concentration, solid liquid ratio of pyrolysis tar and modified solution, calcination temperature and calcination time by 16 group orthogonal experiments. th...

This paper addresses the development of pilot scale sustainable technology for microalgae capture of CO2 from power plant flue gas in alkaline solutions to produce biodiesel from algal oil. A combination of computer tools for process simulation, economic evaluation, and environmental impact allow sustainable process assessment. Laboratory scale experiments for growth and culture for algae in la...

Oxides of nitrogen (NOx) is responsible for troposphere ozone and urban smog through photochemical reactions. The rapid economic growth and unlimited consumption of fossil fuels have resulted in large emissions of NOx. Due to the adverse environmental effects, environmental regulatory agencies are compelled to enforce stringent NOx emission standards. Recently promulgated Clean Air Interstate R...

Samples of active coke, fresh and spent after cleaning flue gases from communal waste incinerators, were investigated. The outer layers of both coke particles were separately removed by comminution in a spouted bed. The samples of both active cokes were analysed by means of densities, mercury porosimetry, and adsorption technique. Remaining cores were examined to determine the degree of consump...

The aim of this work was to study the genetic diversity among flue-cured tobacco cultivars. RAPD and AFLP analyses were used to assess the genetic similarity among selected accessions of flue-cured tobacco. Seventy eight RAPD and 154 AFLP polymorphic bands were obtained and used to assess the genetic diversity among 28 tobacco accessions. The cultivar relationships were estimated through the cl...

NOx removal from an actual boiler flue gas was investigated using a commercial ozonizor for indirect NO oxidation and a scrubber using Na2SO3 . The flue gas was in the range of 470~1,480 Nm/h, the gas temperature of 327C, and NOx concentration of 40 ppm. Approximately 80% of NOx removal efficiency was achieved during 180 min of system operation by maintaining pH of 8 and oxidation reduction pot...
