We have isolated and characterized the cDNA and genomic DNA coding for a phenoloxidase, laccase I, previously purified from culture supernatant of the newly isolated ligninolytic basidiomycete PM1 (CECT 2971). A cDNA library from basidiomycete PM1 was constructed, and laccase-encoding cDNAs were identified by screening with antiserum raised against the purified enzyme. The lac1 gene coding for ...

Vocal behavior in tropical hummingbirds is a new area of study. Here, we present findings on the vocalizations and associated behaviors of two species: Sombre Hummingbird (Aphantochroa cirrhochloris) and Rufous-breasted Hermit (Glaucis hirsutus). These are the only hummingbirds in which the brain areas activated by singing have been demonstrated. They are also among the basal species of their r...

During August and September 1988, we collected adult mosquitoes from 14 locations in the Senegal River basin to search for evidence of Rift Valley fever (RVF) viral activity one year after the 1987 outbreak, which occurred along the Senegal-Mauritania border. More than 62,000 specimens representing 18 species in seven genera were collected with carbon dioxide-baited, solid-state Army miniature ...

In this paper, we study numerical solutions of the time-space fractional wave equation in a complex domain. The fractional time is taken in the sense of the RiemannLiouville differential operator while the fractional space is assumed in the SrivastavaOwa differential operator. Here we employ some properties of the univalent functions in the unit disk to determine the upper bound of this solutio...

Before we proceed with rigorous formulations and applications, we want to give a very informal and “easy-to-visualize” description of one of the central results of the paper. Assume that we are given an n-plane P ⊂ RN , n < N , a collection of oriented n-planes ei, i = 1, 2, . . . k, and a collection of positive reals ai, i = 1, 2, . . . k. We want to know whether there exists an oriented polyh...

Due to the emergence of antibiotic resistance in pathogenic microorganisms, it is urgent search for producers new antimicrobial metabolites. Actinomycetes are gram-positive mycelial bacteria that produce a large number antibiotics used medicine and agro-industrial complex. Currently, researchers focused on actinomycetes ecological niches such as freshwater marine reservoirs, zones with extreme ...
