POST- NAUPLIAR STAGES OF"ACARTIA (ACARTIELLA) FAOENSIS" , KHALAF (COPEPODA : CALANOIDA ), FROM KHOR AL-ZUBAIR SOUTH OF IRAQ
No full textAcartia (Acartiella ) faoensis has been established by the author,(Khalaf, 1991) from Khor Al-Zubair and Khor Abdulla NW Arabian Gulf. It passes through six copepodite stages identical with most other copepods; the last stage is the adult. Description, illustration and measurements for every stage are presented
Extraction and identification of Carnosines from Alkhshni Fish Liza abu L. by using different techniques
No full textCarnosines were extracted from alkhshni fish Liza abu L. by using alcohol and water separation,Carnosines were identificated in several ways including spectroscopy identification using UV-visible and Fourier Transform infrared spectrophotometer technology and High Performance Liquid Chromatography (HPLC), spectral diagnostics using Ultraviolet-visible (UV) carnosines single peak showed at 215 nm wavelength and at diagnosis High Performance Liquid Chromatography (HPLC) retention time stood for standard carnosines 2.532 and author carnosines separated from 2.614 minutes alcoholic carnosines and 2.625 minutes aqueous carnosines, after undetecting the detection of toxicity assay of carnosines prepared on human blood serum and there have been no changes in its shape and appearance.
Iowa History and Culture : A Bibliography of Materials Published Between 1952 and 1986, 1989
No full textThis bibliography was compiled by two reference librarians, Patricia Dawson and David Hudson with the goal of making it easier of tracking down material on Iowa history and culture. This supplements the Iowa History Reference Guide published in 1952 by William Petersen
Marine tephrochronology: a personal perspective
No full textThis special volume on marine tephrochronology is remarkable, and timely, because it marks a concerted step towards what might be informally termed ‘phase 3’ of a revolution in Quaternary geosciences that began around 40 years ago. The 10 articles collectively represent a re-focussed examination of tephras and cryptotephras preserved in ocean sediments at various locations and the authors describe their significance for a range of subdisciplines. Eight articles provide a new understanding of the origin, distribution and ages of various tephra and cryptotephra deposits and their stratigraphic inter-relationships; how the terrestrial ages of the tephra/crypotephra deposits relate to those of enclosing sediments and inform the ongoing development of the marine radiocarbon time-scale; mechanisms for the emplacement, remobilization or bioturbation of the tephras or cryptotephras; and volcanic eruption history. Two further articles document the characterization of tephra-derived glass shards using microbeam techniques to analyse 30–40 elements from individual shards as small as 10 µm in diameter. The collection thus provides snapshots of many aspects of the latest developments and directions in tephra studies – volcanology, primary and secondary dispersal, stratigraphy, single-grain characterization, chronology – through the medium of marine sediments. My personal perspective reflects briefly on how this point was reached and identifies a few of the important milestones on the way from ‘phase 1’ to ‘phase 3’. I am privileged to write it. Marine science revolution As an undergraduate in the early-mid 1970s, I recall my first real ‘awakening’ regarding the dynamic nature of science, and of Quaternary geoscience in particular, when told about deep-sea core V28-238 from the equatorial Pacific Ocean (Shackleton & Opdyke 1973; >2650 citations, Google Scholar). Analogous to the opening notes of Beethoven's 5th Symphony, perhaps the most famous quartet of notes in history, the alpha-numerical assemblage ‘V28-
The ACER pollen and charcoal database
No full textQuaternary records provide an opportunity to examine the nature of the vegetation and fire responses to rapid past climate changes comparable in velocity and magnitude to those expected in the 21st century. The best documented examples of rapid climate change in the past are the warming events associated with the Dansgaard-Oeschger (D-O) cycles during the last glacial period, which were sufficiently large to have had a potential feedback through changes in albedo and greenhouse gas emissions on climate. Previous reconstructions of vegetation and fire changes during the D-O cycles used independently constructed age models, making it difficult to compare the changes between different sites and regions. Here we present the ACER (Abrupt Climate Changes and Environmental Responses) global database which includes 93 pollen records from the last glacial period (73-15 ka) with a temporal resolution better than 1,000 years, 32 of which also provide charcoal records. A harmonized and consistent chronology based on radiometric dating (14C, 234U/230Th, OSL, 40Ar/39Ar dated tephra layers) has been constructed for 86 of these records, although in some cases additional information was derived using common control points based on event stratigraphy. The ACER database compiles metadata including geospatial and dating information, pollen and charcoal counts and pollen percentages of the characteristic biomes, and is archived in Microsoft ACCESS(TM)
