This study presents the application of a set pair analysis-based similarity forecast (SPA-SF) model and wavelet denoising to forecast annual runoff. The SPA-SF model was built from identical, discrepant and contrary viewpoints. The similarity between estimated and historical data can be obtained. The weighted average of the annual runoff values characterized by the highest connection coefficien...
abstract: the potato tuberworm, phthorimaea operculella (zeller), is an important insect pest of potato (solanum tuberosum l.) in the storage and field in most parts of the world especially in tropical and subtropical regions due to its close relationship with the host, high reproductive potential and high economic losses. information on host preference, life table parameters and digestive en...
Immunofluorescence and fluorescent microscopy permit the demonstration of fixation of antibody, previously made fluorescent, on a specific antigen. A direct technic reveals the antigen to which globulins representing the antibodies of immune serum, previously conjugated with a fluorescent substance, are fixed. An indirect technic makes use of antihuman globulins developed in rabbit sera and mad...

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Records of discharge of rivers draining Alpine basins with between 0 and 70% ice cover, in the upper Aare and Rhône catchments, Switzerland, for the period 1894–2006 have been examined together with climatic data for 1866–2006, with a view to assessing the effects on runoff from glacierized basins of climatic warming coupled with glacier recession following the Little Ice Age maximum. Annual ru...
erosion plots were selected for characterizing the effects of main natural factors on runoff and soil loss in a semi-arid region. these erosion plots with an area of 40 m2 are located in the kakhk experimental watershed in gonabad county of khorasan-e razave province in the north-eastern iran. data acquired from 2008 to 2015 include slope, aspect, soil texture and land covers (canopy and litter...
