objective: the current study was undertaken to examine the bactericide effects of atmospheric plasma produced by flat and comb electrodes on e.coli. materials and methods: dc (20 w) and ac (500 w) power supplies, flat and comb electrodes, insulator and oxygen gas were used to produce atmospheric plasma. bactericide effects of the atmospheric plasma were studied on e.coli on sterilized plate pla...
Distantasca Dworakowska originally established as a genus but more recently has been treated as a subgenus of Empoasca Walsh. Here we reinstate Distantasca as a valid genus and provide a revised diagnosis. New combinations created are Distantasca atika (Dworakowska), n. comb., Distantasca barawa (Dworakowska), n. comb., Distantasca bulbosa (Dworakowska), n. comb., Distantasca latava (Dworakowsk...
Cercosporoid fungi (formerly Cercospora s. lat.) represent one of the largest groups of hyphomycetes belonging to the Mycosphaerellaceae (Ascomycota). They include asexual morphs, asexual holomorphs, or species with mycosphaerella-like sexual morphs. Most of them are leaf-spotting plant pathogens with special phytopathological relevance. In the first part of a new monographic work, cercosporoid...
A new genus and species of Chamaemyiidae (Diptera: Lauxanioidea) is described and illustrated, namely Chamaeleucopis, gen. nov. (type species Chamaeleucopis trevas, sp. nov.), a predator of Ceroplastes wax scales on guava from Brazil. In addition, the previously unrecognized genus Ortalidina Blanchard 1852 (type species Ortalidina cellularis Blanchard 1852), mainly from the Neotropics, is recog...
Copy Number Variation has been associated with morphological traits, developmental defects or disease susceptibility. The autosomal dominant Pea-comb mutation in chickens is due to the massive amplification of a CNV in intron 1 of SOX5 and provides a unique opportunity to assess the effect of variation in the number of repeats on quantitative traits such as comb size and comb mass in Pea-comb c...
The bryozoan genus Scrupocellaria comprises about 80 species in the family Candidae. We propose a hypothesis for the phylogenetic relationships among species assigned to Scrupocellaria to serve as framework for a phylogenetic classification using 35 morphological characters. Our results suggest that the genus Scrupocellaria is polyphyletic. Scrupocellaria s. str. is redefined according to four ...
Rose-comb, a classical monogenic trait of chickens, is characterized by a drastically altered comb morphology compared to the single-combed wild-type. Here we show that Rose-comb is caused by a 7.4 Mb inversion on chromosome 7 and that a second Rose-comb allele arose by unequal crossing over between a Rose-comb and wild-type chromosome. The comb phenotype is caused by the relocalization of the ...
Comb method is an efficient method to calculate point multiplication in elliptic curve cryptography, but vulnerable to power-analysis attacks. Various algorithms have been proposed recently to make the comb method secure to power-analysis attacks. In this paper, we present an efficient comb method and its Simple Power Analysis (SPA)-resistant counterpart. We first present a novel comb recoding ...
a study was carried out to evaluate the secondary sexual characteristics of four strains of cocks, comprising of two (2) exotics; bovan nera black (bnb) and isa brown (isb), one (1) improved local strain, shika brown (sb) and one (1) unimproved local strain, normal feathered cock (nfc). a total of 64 birds (16 for each strain) at 36, 38, 40 and 42 weeks were used for the study. the result indic...
Accurate fossil identification has become increasingly relevant with the widespread use of phylogenetic divergence time estimation methods, which rely on fossil data to determine clade hard-minimum ages. Here we revise, diagnose and illustrate known spider wasp (Hymenoptera: Pompilidae) fossil species and place them within the latest Pompilidae phylogenetic hypothesis. Ceropalites infelix Cocke...
