background : according to the national strategy plan on monitoring of insecticides resistance, this study was carried out to determine the base line susceptibility of the culicidae mosquitoes to the who-recommended insecticides in an endemic focus of malaria in southeastern iran. methods : larval collection was carried out by dipping method and adult collection occurred by suction tube from jan...

objective: the use of hema as a biocompatible material in dentin bonding systems and its potential for clinical applications has been well established. excess water can affect conversion of bonding resins. the aim of this study was to survey the effect of water on the degree of conversion of hema by fourier transform infra-red spectroscopy (ft-ir). materials and methods: in this experimental st...

The study of fungal antibiotics in their competitive interactions with arthropods may lead to the development novel biorational insecticides. Extracts Alternaria tenuissima MFP253011 obtained using various methods showed a wide range biological activities, including entomotoxic properties. Analysis composition and bioactivity allowed us reveal several known mycotoxins unidentified compounds tha...

The aim of this study is to investigate ionic liquids (ILs) pretreatment on kempas composition, structure and enzymatic digestibility. Ground kempas (Koompassia malaccensis) was pretreated with 1-butyl-3-methylimidazolium acetate ([Bmim][OAc]), 1-butyl-3-methylimidazolium chloride ([Bmim]Cl) and 1-butyl-3-methylimidazolium trifluoromethansulfonate ([Bmim][OTf]), at 120°C for 6 and 12 h. The cel...

Five lignin samples were fractionated with Acetone/Water mixtures and the obtained fractions were subjected to extensive structural characterization, including Fourier Transform Infrared (FT-IR), Gel permeation Chromatography (GPC) and Phosphorus-31 NMR spectroscopy (P-NMR). The results showed that for all studied lignins the solubility increases with the increment of the acetone concentration....

Arguments are presented for the odderon intercept being exactly equal to unity. A variational method is presented based on a complete system of onegluon functions. For the odderon, the highest intercept calculated by this method is 1− (3αs/π) 0.45. March 1996 hep-ph/9603218 US-FT/7-96 ∗ Visiting Professor IBERDROLA. On leave of absence from the Department of High Energy Physics, University of S...

The white grub Laniifera cyclades Druce of prickly pear cactus or nopal is a pest that limits the commercial production of Opuntia . The gregarious larvae perforate the cladodes devouring the inner part, thereby forming large galleries until reaching the central axis of the plant; during their movement through the inner part of the cactus, the larvae make orifices to the exterior to expel their...

Arabidopsis thaliana (L.) Heynh. has been described as a freezing-tolerant species based on freezing-resistance assays. Nonetheless, this type of experiment does not discriminate between freezing-tolerance and freezing-avoidance mechanisms. The purpose of this paper was to determine which of these two freezing-resistance mechanisms is responsible for freezing resistance in A. thaliana. This was...

The virulence of two products of the fungus Beauveria bassiana (LCPP and Bassianil) on adult Anastrepha ludens (Loew) (Diptera: Tephritidae) and their effect on the mating performance of infected males was evaluated in laboratory and field cage tests. The horizontal transmission capacity of the fungus during copulation or attempted copulation also was quantified using inoculated males as well a...
