Ash layer characteristics and major element oxide content of glasses from ODP Sites 162-982 and 162-985
No full textThe Cenozoic volcanic activity on Iceland has been recorded in North Atlantic sediments drilled during several Ocean Drilling Program (ODP)/Deep Sea Drilling Project legs (Legs 104, 151, 152, 162, and 163). Leg 162 (North Atlantic-Arctic Gateways II) recovered ash layers at Sites 982, 985, and 907 (Jansen, Raymo, Blum, et al., 1996, doi:10.2973/odp.proc.ir.162.1996). The revisited Site 907 was first drilled during Leg 151, and the ash from this site has been described in detail by Lacasse et al. (1996, doi:10.2973/odp.proc.sr.151.122.1996) and Werner et al. (1996, doi:10.2973/odp.proc.sr.151.123.1996). Site 982 is located within the Hatton-Rockall Basin on the Rockall Plateau, which is situated west of the British Isles. Site 985 is located northeast of Iceland at the foot of the eastern slope of the Iceland Plateau, adjacent to the Norwegian Basin. Here we report chemical analyses of Neogene tephra layers from Holes 982A, 983B, 982C, 985A, and 985B.
The sedimentary sequence at Site 982 spans the lower Miocene-Holocene; Site 985 recovered sediments spanning the upper Oligocene-Holocene. Twenty-two distinct ash layers and ash-bearing sediments were sampled in Holes 982A-982C (Cores 162-982A-16H through 24H, 162-982B-14H through 56X, and 162-982C-15H through 27H), and 59 ash layers were sampled in Holes 985A and 985B (Cores 162-985A-11H through 59X, and 162-985B-11H through 14H). Almost 50% of the sampled ash is strongly altered (predominantly from Site 985). A cluster of altered thin layers in the lower Pliocene of Site 985 (top of Unit III) is remarkable
Grain size data from ODP Site 162-985
No full textRecords of grain size data measured on the coarse fraction of sediment samples taken during Ocean Drilling Program Site 985 from the Norwegian Sea. For the studies of the coarse fraction the samples were freeze-dried using a FINN-AQUA (lyvotac GT2). Part of the freeze-dried sample was weighed and then washed on a 63-µm sieve and further separated into 63- to 125-, 125- to 500-, 500- to 1000-, and >1000-µm fractions using an ATM-SONIC-Sifter. The 125- to 500-µm fraction was chosen for particle count procedure
A study on the cellular and cytotoxic effects of S and Se heterocycles on the myeloid leukemia cell line PLB-985
No full textThis paper describes the synthesis of several halogenated S and Se heterocycles and tests their biological activity by measuring the effects on the myeloid leukemia cell line, PLB-985 cells. We report that select compounds exhibit significant increases in mitochondria membrane potential and increased oxidative stress in PLB-985 cells. In addition, several compounds caused cytotoxicity at high cell densities. Our results contribute to the foundational knowledge of different S and Se containing compounds and their possible impacts on human cells.</p
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
