The mosquito vector Aedes aegypti L., plays an important role in transmission of diseases including dengue, chikungunya and zika fever. In this study, citronella leaf oil extracted by hydro-distillation technique has been evaluated for its efficacy against vector. Citronella (100, 125, 150, 175 200 ppm) when tested, 150 ppm was found to be the effective larvicidal concentration 4th instar larva...

the fruit of melia azedarach l. (meliaceae) was extracted with hexane, and its fatty acids methyl ester was analyzed using gc/ms. thirteen components representing 85.1% of the total extract were identified. the major components identified were methyl palmitate (18.8%), methyl linolenate (16.1%) and methyl linoleate (9.8%). the fruits’ extract had a lc50 of 5.5 ppm against the larvae of anophles...

Interlanguage pragmatics (ILP) has witnessed a growing body of research in the past two decades. One of the under-explored domains of L2 pragmatics is the role of learning strategies specifically tailored for the development of ILP knowledge. Therefore, this investigation aimed to determine the significant interlanguage pragmatic learning strategies (IPLS) used by high vs. low L2 pragmatic achi...

to study and determine  effect of salinity on relationship between  agronomic  characteristics and grain yield, 167  of  the  seri/babax recombinant wheat inbred  lines (ril) together with two parents were evaluated using alpha latice design with two replications under two conditions (salt stress and normal), in zabol field station in 2011-12 cropping season. fourteen  traits  including: some a...

Six components used in vaginal tampons were tested for their effects on a strain of Neisseria gonorrhoeae isolated from a patient with disseminated infection. Tampon components containing carboxymethyl cellulose or its derivative prolonged the in-vitro survival of gonococci and, when injected with mucin into mice, significantly (P less than 0.0001) increased the dissemination of gonococci from ...
