background: the traditional cyclone has been developed for the removal of airborne silica particles from local exhaust ventilation (lev). the objective of this research was to evaluate the effects of velocity and particles load on efficiency of cyclone in the stone crushing units at azendarian area. methods: after the designing and installing the traditional cyclone, downstream and upstream sam...

UNLABELLED Cyclone aims at facilitating the use of BioCyc, a collection of Pathway/Genome Databases (PGDBs). Cyclone provides a fully extensible Java Object API to analyze and visualize these data. Cyclone can read and write PGDBs, and can write its own data in the CycloneML format. This format is automatically generated from the BioCyc ontology by Cyclone itself, ensuring continued compatibili...

A new theoretical method for computing travel distance, number of turns, and cyclone pressure drop has been developed and is presented in this article. The flow pattern and cyclone dimensions determine the travel distance in a cyclone. The effective number of turns was calculated based on the travel distance. Cyclone pressure drop is composed of five pressure loss components. The frictional pre...

To assess the impact on health of the cyclone and tidal wave that struck the southern coast of Bangladesh on the evening of 29 April 1991, a team of health professionals visited cyclone affected areas from 4-27 June, 1991. Team members met with health workers and officials of the Government of Bangladesh and with staff pom nongovernmental organizations, and conducted field surveys in two severe...

The 30–60-day Madden–Julian oscillation (MJO) has been documented in previous research to impact tropical cyclone (TC) activity for various tropical cyclone basins around the globe. TheMJOmodulates largescale convective activity throughout the tropics, and concomitantly modulates other fields known to impact tropical cyclone activity such as vertical wind shear, midlevelmoisture, vertical motio...

To track a cyclone using a single orbiting satellite in a continuous manner is impractical as it has limited spatial and temporal coverage. One solution is to use multiple orbiting satellites for cyclone tracking. However, data from some orbiting satellites do not provide features as useful as other satellites in identifying cyclones. Moreover, satellite data containing strong cyclone discrimin...

Four cyclone concentrators were designed and fabricated to compare their particle separation and concentration behavior, such as the major, minor, outlet, and wall deposition fractions. Two of the cyclone concentrators were the conventional type, with the minor flow tube connected to the particle outlet at the bottom of the cyclone. The others were modified cyclone concentrators with a gap betw...

The effect of adding extra inlet channels on the operation of the Stairmand Cyclone has been investigated numerically. The Reynolds stress model (RSM) and Eulerian-Lagrangian method were used to investigate the complex turbulent flow and cyclone performance. The impacts of one-way coupling and two-way coupling models on the cyclone efficiency and the calculation of cut-off size diameter were ex...

• The damage to older buildings in the areas suffering the most wind damage was very similar to the damage in the most damaged areas in the Whitsunday Islands from Cyclone Ada in January 1970, Townsville from Cyclone Althea in December 1971, and older buildings in Innisfail from Cyclone Larry in March 2006, not much greater than in the worst affected areas of Cyclone Winifred in 1986, and an or...
