Determining the magnetic field of solar spicules is vital for developing adequate models of these plasma jets, which are thought to play a key role in the thermal, dynamic, and magnetic structure of the chromosphere. Here we report on magnetic spicule properties in a very quiet region of the off-limb solar atmosphere, as inferred from new spectropolarimetric observations in the He I 10830 Å tri...

Background Sublethal parasite infections may cause mortality indirectly by exposing the host to predation. The best known example of this among birds is red grouse in which caecal nematode infection causes increased risk of predation and can even affect population dynamics [1]. Intestinal helminth parasites are common in forest grouse, capercaillie Tetrao urogallus, black grouse Tetrao tetrix a...

Staphylococci are a major health threat because of increasing resistance to antibiotics. An alternative to antibiotic treatment is preventing virulence by inhibition of bacterial cell-to-cell communication using the quorum-sensing inhibitor RNAIII-inhibiting peptide (RIP). In this work, we identified 2',5-di-O-galloyl-d-hamamelose (hamamelitannin) as a nonpeptide analog of RIP by virtual screen...

Walker, Hazel (University of Georgia, Athens), and R. G. Eagon. Lactic dehydrogenases of Pseudomonas natriegens. J. Bacteriol. 88:25-30. 1964.-Lactic dehydrogenases specific for d- and l-lactate were demonstrated in Pseudomonas natriegens. The l-lactic dehydrogenase showed considerable heat stability, and 40% of the activity remained in extracts after heating at 60 C for 10 min. An essential th...

The term, grotesque is a technique that used to unite oppositions such as comedy and horror, pleasure repulsion. Originally appearing in Renaissance art, the was also employed literature. Thomas Mann claims “the its most genuine style” (1991: 13) , because of sense loss, alienation meaninglessness caused by Great War. In terms theme alienation, two protagonists Hazel Motes from Flannery O’Conno...

Cultured callus tissue of hazel (Corylus avellana L.), which has the potency of somatic embryogenesis, was used for the study of cell ultrastructure in the course of callus growth and embryoid formation. The meristematic cells of this tissue exhibit a specific organization of rough endoplasmic reticulum (RER), stacked into extensive parallel sheets. The membranes of the aggregated RER are assoc...
