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...
in this study two intelligent systems, based on adaptive neuro-fuzzy inference systems (anfis) and artificial neural networks (anns) of forecasting municipal solid wastes (msw) generation has been proposed. anfis and anns as an intelligent tool compared with together was used to monthly prediction of msw generated in tehran. monthly amount of solid wastes (sw), total monthly precipitation, mont...
to compensate for some inferior properties of recycled papers, application of processing chemical aids such as chitosan can be quite effective in the wet end section of papermaking. in this study, the performance of chitosan biopolymer, individually or associated with nanobentonite was investigated as wet end additive on recycling process of white cuttings. for this purpose, the performance of ...
an investigation was conducted on the effects of vermicompost as an organic matter and a substitute for fertilizers during year 2007 in ferdowsi university of mashhad (fum). vermicompost was applied at five levels (0, 10, 25, 50, 100%) and phosphorus at two levels with 3 replications for each treatment, as a factorial based on completely randomized design for super strain b tomato cultivar. the...
introduction numerous studies have demonstrated the relationship between the amount of co2 in the atmosphere and climate change. in this respect, developed countries have an undeniable role and cause serious damage to earth environment throughout the world. ipcc’ forth evaluation report implies that adding greenhouse gases to the atmosphere during recent decades prevents the heat rays to emit w...
earthworms are an important part of food chain in soil ecosystem. in polluted soils, heavy metals are consumed by earthworms and transferred to other organisms through food chain, resulting in many adverse health impacts. due to the benefits of earthworms for soil fertility, it is important to assess the effects of soil pollution on population, biomass and functions of earthworms. to determine ...
calla lily, an ornamental bulbous plant from araceae family (consisting of seven species) is characterized by spadix inflorescence and utilized for cut flower as well as for pot plant. a greenhouse study was conducted in university college of agriculture and nature resources of tehran university, to evaluate the quantitative and qualitative characteristics of pot plant of calla lily. the type o...
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...
background: viscerotropic leishmaniasis caused by leishmania tropica poses a significant problem in the diagnosis and treatment management. since differential gene expression is more important in outcome of the infection, we employed proteomic approach to identify potential proteins involved in visceralization of l. tropica . methods: the proteomes profiling of l. tropica isolated from cutan...
