root rot disease of broad-bean caused by fusarium solani is a serious disease of this crop. due to high cost and difficulty of the disease control, interaction between root nodulating bacteria and fusarium. solani were evaluated to use for disease management. broad-bean root nodulating bacteria were isolated and their interaction with f. solani was investigated in culture medium in a completely...

a novel and ultra low cost isfet electrode and measurement system was designed for isfet application and detection of hydronium, hydrazinium and potassium ions. also, a measuring setup containing appropriate circuits, suitable analyzer (advantech board), de noise reduction elements, cooling system and pc was used for controlling the isfet electrode and various characteristic measurements. the t...

  Background and purpose: Pesticides can accumulate in the body due to chronic toxicity. This accumulation is caused by direct exposure to the chemicals or indirect exposure, i.e. foods, breathing, and skin. This study was performed to assess the levels of diazinon and malathion residues in cucumber produced in Mazandaran province, Iran. Materials and methods: In this experimental study,...

We conducted sentinel-based surveillance for norovirus in the Pudong area of Shanghai, China, during 2012-2013, by analyzing 5,324 community surveys, 408,024 medical records, and 771 laboratory-confirmed norovirus infections among 3,877 diarrhea cases. Our analysis indicated an outpatient incidence of 1.5/100 person-years and a community incidence of 8.9/100 person-years for norovirus-associate...

A series of new dispiro[fluorene-9',6,9'',12-indeno[1,2b]fluorenes] (DSF-IFs) has been synthesised. These new building blocks for blue-light-emitting devices and electroactive polymers combine indenofluorene (IF) and spirobifluorene (SBF) properties. We report here our synthetic investigations towards these new structures and their thermal, structural, photophysical and electrochemical properti...

Cucumber mosaic virus (CMV) is one of the causal agents of viral diseases that infected mint (Mentha spp.). CMV is a member of the cucumovirus genus in  Bromoviridae family. The virus is naturally transmitted by aphids in a non-persistent manner.During  growing season 2007-2008, leaf samples from plants of mint fields with symptoms of viral disease were collected in mint fieldas in Tehran provi...

The state of Oklahoma has experienced an unprecedented increase in earthquake activity since 2009, likely driven by large-scale wastewater injection operations. Statewide injection rates peaked in early 2015 and steadily decreased thereafter, approximately coinciding with collapsing oil prices and regulatory action. If seismic activity is primarily driven by fluid injection, a noticeable seismo...

We review the "critical point" concept for large earthquakes and enlarge it in the framework of so-called "finite-time singularities." The singular behavior associated with accelerated seismic release is shown to result from a positive feedback of the seismic activity on its release rate. The most important mechanisms for such positive feedback are presented. We solve analytically a simple mode...

Robert Anthony Department of Earth and Environmental Science, New Mexico Institute of Mining and Technology Abstract Since the early 1960s when Maruyama and Burridge and Knopoff convincingly demonstrated that the elastodynamic radiation patterns exhibited by shear faulting in an isotropic, elastic medium were consistent with a pair of force couples, it has become standard practice amongst seism...
