Legionella pneumophila (Legionnaires disease bacterium) of serogroup 1 was isolated from an algal-bacterial mat community growing at 45 degrees C in a man-made thermal effluent. This isolate was grown in mineral salts medium at 45 degrees C in association with the blue-green alga (cyanobacterium) Fischerella sp. over a pH range of 6.9 to 7.6. L. pneumophila was apparently using algal extracellu...

The cyanobacterium Fischerella ambigua is a natural producer of polychlorinated aromatic compounds, the ambigols A–E. Here insights into biosynthesis these products are revealed.

This paper deals with the development of two symmetric encryption algorithms on basis cellular automata: a block cipher, that is based AES and uses three-dimensional automata; stream exploits hardware-software entropy generation (tracking keystrokes mouse pointer movement), as well developed hash function, “cryptographic sponge” architecture SHA-3, modified by automata transformations. The ciph...

background and aim: sinusoidal harmonic acceleration (sha) test is one of the most effective and best-tolerated methods to assess vestibular system function, especially horizontal semicircular canal in children. a prerequisite for using this test in children, is the availability of normative data. despite of the numerous studies related to the sha in adults, few researches have been documented ...

Blood-type B specific hemagglutinin (L-rham/D-gal-specific lectin) secreted by Streptomyces sp. 27S5 (SHA) was purified over 40 years ago. Despite the loss of original strain and lack genomic information, amino acid sequence its SHA recently determined based on peptides matching to a hypothetical protein S. lavendulae, differing only single acid, A108E (J Biol Chem 293:368, 2018). Recombinant (...

In the draft FIPS 180-2, NIST published SHA-2 as a new version of secure hash algorithm. SHA-2 offers four secure hash algorithms including SHA-1, SHA-256, SHA-384, and SHA-512. In other words, SHA-2 may have outputs 160, 256, 384, or 512 bits of message digest. However, SHA-2 algorithm uses fixed and predefined parameters in execution. It may be vulnerable to attacks. In this paper, we propose...

CONTEXT Gluteus medius (Gmed) weakness is associated with some lower-extremity injuries. People with Gmed weakness might compensate by activating the tensor fasciae latae (TFL). Different hip rotations in the transverse plane may affect Gmed and TFL muscle activity during isometric side-lying hip abduction (SHA). OBJECTIVES To compare Gmed and TFL muscle activity and the Gmed:TFL muscle-activ...
