a field experiment was conducted to evaluate the effect of varying doses of haloxifhope-r-methyl ester herbicide on grass weeds grown at various stages in 2011-2012 growing season in research farm of college of agriculture, shiraz university. the study was carried out as split split plot based on randomized complete block design with three replicates. treatments were haloxifhope-r-methyl ester ...
Study on Synthesis and Characterization of Unsaturated Poly (ester-amide) as Bone Fixation Materials
A new type of unsaturated poly ester-amide was prepared by melt polycondensation and characterized completely. Influence of heat treatment conditions and cross-linking content on mechanical and degradation properties of unsaturated polyester-amide were studied. Results suggested that the newly synthesized unsaturated poly(ester-amide) possessed good heat stabilization properties. Mechanical...
In order to evaluate the potential of citogate and turnip vegetable oil in increasing the performance of barnyardgrass (Echinochloa crus-galli) control by colthodim and haloxyfop-r-methyl ester herbicides, two greenhouse experiments were carried out in the Research Greenhouse of the Faculty of Agriculture, Birjand, Iran, in 2016; this study was based on a factorial arrangement as a completely r...
Poly(ester-carbonate) copolymers were synthesized through triethylborane (TEB)-activated, one-pot copolymerization of epoxides with anhydrides (AH) and CO₂. Depending upon the feeding ratio AH to epoxides, poly(ester-carbonate) random tapered ester structures could be derived due much higher reactivity toward growing oxanions compared Anhydrides like succinic anhydride (SA) phthalic (PA) when t...
background: cocaine poisoning is known for causing severe clinical effects such as tachycardia, hypertension, agitation and confusion. absence of clinical manifestations in cocaine poisoning is unusual. case report: a 26-year old man, known to be a cocaine addict, declared that he was forced by cocaine dealers to swallow many tablets of cocaine, six hours prior to admission to emergency departm...
the adducts produced in the reaction between trialkyl phosphites and acetylenic esters were trapped by hydantoins to produce highly functionalized dialkyl 2-(2,5-dioxo-4,4-diphenylimidazolidin-1-yl) succinate in good yields.
Polyvinyl ester green composites were synthesized with walnut shell powder (WSP) by in-situ polymerization technique. The green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. Sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...
subsequent to phytochemical investigation on scutellaria lateriflora (labiatae) from mazandaran provincein iran, the wax ester fraction of the leaves has been investigated. using tlc, cc glc and glc-ms, the alkyl esters of the epicuticular wax was analysed. total concentration of the esters was 35% and it was shown to be composed of a homologous series having various chain lengths in the range ...
