in order to obtain high yielded and tolerant to drought stress maize hybrid a breeding program was started in safiabad agricultural research center in the 1999 and a few s6 lines attained in 2005. then interactive components were created and evaluated in the preliminary and semi-finals experiment during two consecutive years. after preliminary studies, nine hybrids were selected which they were...
iron oxide minerals in soils provide valuable insights into pedogenic processes. a wealth of such information has been obtained by rock magnetic investigations on temperate soils but similar studies on tropical soils are rare. here, we report rock magnetic data on pristine soil profiles and surficial soils from five catchments in the tropical southern india and throw light on the pedogenic pro...
the plankton and semi-plankton samples examined from mizoram state of northeast india (nei) revealed speciose and diverse rotifera assemblage including a total richness (s) of 162 species belonging to 19 families and 35 genera. the reports of six species new to india, four species new to nei and 76 new records to mizoram merit biodiversity interest. the occurrence of one australasian, one orien...
gonu storm was formed in tropical basin of indian ocean early in june 2007. gonu is the strongest tropical cyclone that happened in arabian sea and north indian ocean and moved toward oman sea and persian gulf and bouncing the lands around the area. this tropical cyclone made extensive damages and human and financial causalities to countries of oman, iran, afghanistan, pakistan, and india. in t...
Part I of this two-part paper treats Tropical Rainfall Measuring Mission (TRMM) radar, passive microwave, and lightning observations in hurricanes individually. This paper (Part II) examines relationships between these parameters (and implications of the relationships). Quantitative relationships between lightning occurrence and 85-GHz brightness temperature, 37-GHz brightness temperature, and ...
Previous studies have indicated that recurving western North Pacific tropical cyclones, initially westward moving tropical cyclones that turn toward the east, often reach their maximum intensity close to the time of recurvature. Those results have often been cited in the literature and sometimes inferred to be valid in other tropical cyclone basins. This study revisits this topic in the western...
The early diverged Magnoliaceae shows a historical temperate-tropical distribution among lineages indicating divergent evolution, yet which ecophysiological traits are phylogenetically conserved, and whether these traits are involved in correlated evolution remain unclear. Integrating phylogeny and 20 ecophysiological traits of 27 species, from the four largest sections of Magnoliaceae, we test...
Remote sensing indices are used to analyze the Spatio-temporal distribution of drought conditions and to identify the severity of drought. This study, using various drought indices generated from Madis and TRMM satellite data extracted from Google Earth Engine (GEE) platform. Drought conditions in Marivan city from February to November for the years 2001 to 2017 were analyzed based on spatial a...
rutting of hot mix asphalt pavements due to increased number of heavy vehicles, especially in tropical regions, causes several performance problems. large stone asphalt mixtures have more stiffness and shear resistance and so more rutting resistance compared to conventional mixtures. hence, using these mixtures in thick layers of hot mix asphalt pavements at tropical regions could be an appropr...
introduction ophthalmomyiasis is a rare disorder that is caused by invasion of dipterous larvae to necrotic tissues. case presentation an 80-year-old woman with invasive basal cell carcinoma (bcc) presented anabnormal growth of worm in her eye. she had ophthalmomyiasis caused by lucilia sericata larva in here nucleated eye. l. sericata is common all over the temperate and tropical regions, main...
