sexual behavior in most moths is limited to a precise duration period of either the day or the night. these behaviors as well as the calling behavior are specific. information on reproductive behavior is important in the chemical ecology studies. experiments were conducted to determine the developmental biology, adult time emergence and calling behaviors of three populations of carob moth, ecto...

introduction water vapor can spread in molecular, unstable and erratic phase and can also transfer by convection and advection process. this transfer happens from the earth and ocean surfaces to the atmosphere in hot air. this type of transfer is considered as the main pattern. in the studies of the atmosphere, one of the prominent factors to be considered is the complexity of water vapor and i...

1. introduction isfahan oil refinery (isfahan, iran) is responsible for the production of huge amounts of oil waste. as the released organic compounds are highly toxic, carcinogenic, and mutagenic, they can potentially contaminate the soil and groundwater resources of the adjacent area. this is particularly important in isfahan where arid/semi-arid climate has limited the access to adequate sur...

hybrid rice varieties are potentially higher yielding than the best inbred varieties and perform better under adverse conditions of drought and salinity. one of the major impediments for seed production of hybrid rice is incomplete panicle exsertion in the cytoplasmic male sterile lines. the unexserted spikelets which are left inside the flag leaf sheath remain unfertile. this research was focu...

one of the most important atmospheric systems in the eurasian continent during the northern hemisphere winter season is the siberian high pressure. in this study, using the ncep/ncar reanalysis data for winters of 1948-2008, trend of changes in the intensity of the high system center and its effects on some meteorological fields are investigated. the results show that the 2m height mean tempera...

japan is a region of active plate tectonics, well known for its japanese trench a geological feature evolving as a result of north pacific (np) oceanic plate pushing and sub-ducting underneath the north american (na) plate. multiple plate tectonics have been continuously recorded in the region since 1979 by the network of gps stations called geonet. the network operating and monitoring more tha...

shortage of irrigation water, being a crucial problem in arid and semiarid regions, makes it necessary to use treated wastewater in agriculture. a field experiment was conducted to investigate the effect of treated municipal wastewater (tmw) on the yield and fiber quality of cotton (gossypium hirsutum l.) (mehr variety). treated municipal wastewater was supplied from shahrake ghods sewage treat...

activities of thirty bacterial strains obtained from plants rhizosphere in different areas against phytophthora drechsleri were assessed through in vitro and greenhouse experiments. dual culture and extracellular metabolites tests were used in in vitro assays. the bacterial strains inhibited growth of p. drechsleri, the highest inhibition zones was belonged to t17-4 strain with 61.904% in dual ...

in this research, moisture sorptions of sayer date were determined at 20, 30, 40 and 60°c, using the standard static gravimetric method developed by the european cooperation project cost 90. several mathematical models, namely gab, bet, iglesias & chirif and halsey were employed to fit the experimental data through non-linear regression. results indicate that equilibrium moisture content increa...

low seed germination and seedling emergence is one of the main problems in saline areas. seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stress. the objective of this research was to evaluate the effect of seed priming with gibberellin, nacl and water on seed germination and seed reserve utilization and germination...
