Accurate palyno-analysis by S. Loboziak (from 1980 to 1983) of 28 samples from the Upper Givetian Middle Frasnian Blacourt, Beaulieu and Ferques Formations 44 Lower Famennian Hydrequent Formation are re-evaluated. Chelinospora concinna, Verrucosisporites bulliferus, Cirratriradites jekhowskyi, Lophozonotriletes media first occurrences major criteria for Frasnian, well calibrated conodonts. Cymb...

The leaves of Acacia nilotica (L.) Delile was extracted with methanol and aqueous medium and studied for in vitro antimicrobial property. The methanol extract was found to be most active against all the bacterial species tested except S.aureus. Active methanol extract was further studied for HPTLC fingerprint and by phytochemical analysis. HPTLC analysis confirmed segregation of four individual...

The adsorption technique using chemically treated powder of bark of Acacia arabica was applied for the removal of toxic heavy metals from polluted waste water. The extent of adsorption found to be dependent on the pH and the time of contact. The adsorbent is effective for the quantitative removal of various toxic metals from the contaminated aqueous sample. The method is quite feasible, economi...

The aim of the present study was to introduce an alternative way for insects control through biodegradable plants materials. The different cold water extracts dilutions of Acacia modesta and Glycyrrhiza glabra were tested against Tribolium castaneum. The extracts dilutions of both plants caused mortality of the Tribolium castaneum. ANOVA revealed that dilutions and plants were highly significan...

The southern tip of South America and Antarctica are particularly interesting due to many genera and also species currently sharing between both areas. The genus Nacella (Patellogastropoda: Nacellidae) is distributed in different regions of South America and Antarctica living preferentially on rocks and boulders and grazing on algae, diatoms and bacterial films. We described the transcriptomes ...

Three new species of Salganea Stål, 1877 are described and illustrated: S. quinquedentata sp. n., S. anisodonta sp. n. and S. flexibilis sp. n. S. taiwanensis Roth, 1979, S. guangxiensis (Feng & Woo, 1990), S. incerta (Brunner von Wattenwyl, 1893) and S. raggei Roth, 1979 are redescribed. Panesthia concinna Feng & Woo, 1990 is synonymized with S. taiwanensis Roth, 1979 and Panesthia guangxiensi...

For a survey of Coxiella burnetii, the Q fever agent, ticks infesting companion dogs were collected in Aomori, Tochigi, Gifu and Okinawa Prefectures, Japan. A total of 261 ticks were collected, and their species were identified morphologically. Five tick species were identified: Ixodes ovatus, Haemaphysalis concinna, H. flava, H. longicornis and Rhipicephalus sanguineus. Total DNA was extracted...
