In this work, new coumarin based dyes for dye sensitized solar cells (DSSC) have been designed by introducing several substituent groups in different positions of the NKX-2311 structure. Two types of substitutions have been considered: the introduction of three electron-donating groups (-OH, -NH(2), and -OCH(3)) and two different substituents with steric effect: -CH(2)-CH(2)-CH(2)- and -CH(2)-H...

one hundred one cases of urban cutaneous leishmaniasis from mashad and teh ran were placed under treatment with either one or two sim ultaneous standa rd doses of cycloguanil parnoate. out of 101 patients, 96 were followed until the 120th day; 31 (31 per cent ) recovered with in 60 days, ?3 ('3 per cent) recovered utter between 60 and i70 days, and 42 (42 per cent) did not respond. a higher rec...

For a finite group $G$‎, ‎let $Cent(G)$ denote the set of centralizers of single elements of $G$‎. ‎In this note we prove that if $|G|leq frac{3}{2}|Cent(G)|$ and $G$ is 2-nilpotent‎, ‎then $Gcong S_3‎, ‎D_{10}$ or $S_3times S_3$‎. ‎This result gives a partial and positive answer to a conjecture raised by A‎. ‎R‎. ‎Ashrafi [On finite groups with a given number of centralizers‎, ‎Algebra‎ ‎Collo...

The red palm weevil (RPW) Rhynchophorus ferruginous (Olivier) was fully developed and reared on a meridic diet consisting of agar, distilled water, commercial yeast as well as laboratory produced amino and fatty acid rich brewer’s yeast (Saccharomyces cerevisiae), wheat meal, corn flour, benzoic acid, ascorbic acid, sorbic acid, vitamin mix and tetracycline hydrochloride. A group of weevils rea...
