(American Society for Microbiology, 2005-11-01)Eight anaerobic granular sludges were surveyed for Crenarchaeota using rRNA gene cloning. Microbial arrangement and substrate uptake patterns were elucidated by fluorescent in situ hybridization and beta imaging. Group 1.3 ... -
The distribution, type, popularity, size and availability of river-run gravel and crushed stone for use in land drainage systems, and their suitability for mineral soils in Ireland
(Compuscript for Teagasc (Agriculture and Food Development Authority, Ireland), 2022-06-24)The performance of land drainage systems installed in mineral soils in Ireland is highly variable, and is dependent on, amongst other factors, the quality and suitability of the aggregate used. In Ireland, aggregate for ... -
Distributions of zeros of solutions to first order delay dynamic equations
(Springer Nature, 2017-07-26)This paper is concerned with the distributions of zeros of solutions to first order delay dynamic equations on time scales. The results are obtained using iterative sequences. -
Distributive coset graphs of finite coxeter groups
(Walter de Gruyter GmbH, 2003-01-27)Let W be a finite Coxeter group, W-J a parabolic subgroup of W and X-J the set of distinguished coset representatives of W-J in W equipped with the induced weak Bruhat ordering of W. All instances when X-J is a distributive ... -
Disturbance of the re-os chronometer of molybdenites from the late-caledonian galway granite, ireland, by hydrothermal fluid circulation.
(Geochemical Society of Japan, 2001-01-01)Re-Os ages were determined for molybdenites from the late-Caledonian Galway Granite in the west of Ireland. Molybdenites from three localities within the batholith, Mace Head, Murvey, and Travore, yield respective Re-Os ... -
Disturbing effect of intra-tissue temperature sensors in pre-clinical experimental studies of radiofrequency cardiac ablation: A computer-based modeling study
(MDPI, 2023-04-11)Background: Preclinical studies on radiofrequency (RF) cardiac ablation (RFCA) use very small temperature sensors in specific positions in the tissue subjected to RF heating. Despite the sensors¿ small size, the proximity ... -

Diurnal, synoptic and seasonal variability of atmospheric co<sub>2</sub> in the paris megacity area
(Copernicus GmbH, 2018-03-07)Most of the global fossil fuel CO2 emissions arise from urbanized and industrialized areas. Bottom-up inventories quantify them but with large uncertainties. In 2010-2011, the first atmospheric in situ CO2 measurement ... -

Divergent evolution of the activity and regulation of the glutamate decarboxylase systems in listeria monocytogenes egd-e and 10403s: roles in virulence and acid tolerance
(Public Library of Science (PLoS), 2014-11-11)The glutamate decarboxylase (GAD) system has been shown to be important for the survival of Listeria monocytogenes in low pH environments. The bacterium can use this faculty to maintain pH homeostasis under acidic conditions. ... -
Divergent mechanisms of interaction of helicobacter pylori and campylobacter jejuni with mucus and mucins
(American Society for Microbiology, 2013-05-28)Helicobacter pylori and Campylobacter jejuni colonize the stomach and intestinal mucus, respectively. Using a combination of mucus-secreting cells, purified mucins, and a novel mucin microarray platform, we examined the ... -
Diverse populations of t cells with nk cell receptors accumulate in the human intestine in health and in colorectal cancer
(Wiley-Blackwell, 2004-08-01)T cells expressing INK cell receptors (NKR) display rapid MHC-unrestricted cytotoxicity and potent cytokine secretion and are thought to play roles in immunity against tumors. We have quantified and characterized NKR+ T ... -
Diversifying techniques and neutrality in genetic algorithms
(SciTePress Digital Library, 2016)This paper examines the implicit maintenance of diversity within a population through the inclusion of a layered genotype-phenotype map (GP-map) in a Genetic Algorithm (GA), based on the principal of Neutral theory. The ... -
