Over a hundred species of aquatic birds overwinter in Central America's wetlands, providing opportunities for the transmission of influenza A viruses (IAVs). To date, limited IAV surveillance in Central America hinders our understanding of the evolution and ecology of IAVs in migratory hosts within the Western Hemisphere. To address this gap, we sequenced the genomes of 68 virus isolates obtain...

By the application of an ultra fast magnetic field sweeping (2.0 × 105 T/sec) and the zero-field magnetic resonance (ZFMR)/FID techniques, we are able to probe the dynamics at the level anti-crossing region of the photo-excited triplet states of pentacene-h14 in p-terphenyl (PHPT) and pentacene-d14 in p-terphenyl (PDPT) systems. The crossing is a non-adiabatic passage at such a high jumping rat...

The H-immobilization test of Le Minor for determining flagellar (H) antigens was evaluated and compared with tube and slide H-agglutination tests. The test proved specific and easy to perform, and titration end points were clearly discernible. The degree of serological cross-reactivity between H antigen reference strains of Serratia marcescens was low. Consequently, this test was adopted for ro...

The effects of different sources of carbon, nitrogen and some of trace elements on cultivation of Bacillus thuringiensis H14 were studied. Glucose, glycerol, sodium acetate, (NH4)2SO4, corn steep liquor, yeast extract, hydrolyzed casein, Ca2+, Mg2+ and Mn2+ were the main parameters evaluated by Plackett-Burman statistical method. All el...

Alüminyum ve alaşımları, birçok ürünün üretiminde özellikle uzay, havacılık otomotiv sektörleri başta olmak üzere farklı endüstri alanlarında yaygın olarak kullanılmaktadır. alaşımları düşük yoğunluğu, yüksek korozyon direnci sünekliği, elektrik ısı iletkenliğinin olması ayrıca kolay işlenebilirliği ile karakterize edilebilir. alaşımlarının süneklik değerlerine sahip olması, talaşlı imalatta yü...

background: the incidence of mosquito-borne diseases and the resistance of mosquitoes to conventional pesticides have recently caused a panic to the authorities in the endemic countries. this study was conducted to identify native larvicidal biopesticides against culex pipiens for utilization in the battle against mosquito-borne diseases. methods: larvicidal activities of new indigenous bacillu...
