Hydrogen sulfide oxidation in novel Horizontal-Flow Biofilm Reactors dominated by an Acidithiobacillus and a Thiobacillus species
(Taylor & Francis, 2016-03-17)Hydrogen Sulfide (H2S) is an odourous, highly toxic gas commonly encountered in various commercial and municipal sectors. Three novel, laboratory-scale, Horizontal-Flow Biofilm Reactors (HFBRs) were tested for the removal ... -
Hydrogeophysics of coastal aquifers - geophysical applications to the assessment of groundwater properties in coastal gravel and karst aquifers
(2017-05-19)Airborne, terrestrial and marine geophysics have been employed to examine coastal zone hydrogeology in two very different aquifer types in Ireland. Modelling of regional airborne electromagnetic data informed by ground-based ... -
Hydrology and management of turloughs (temporary lakes) affect marsh fly (sciomyzidae: diptera) communities
(Wiley-Blackwell, 2009-11-01)Hydrology and management affect dipteran communities in wetlands and they, themselves, have the potential to influence prey communities. Turloughs are temporary lakes unique to Ireland. Their vegetation is ecotonal on a ... -
Hydrology in perspective

Hydrolysis, methanogenesis and bioprocess performance during low-temperature anaerobic digestion of dilute wastewater
(2015-04-28)Anaerobic digestion (AD) technologies represent sustainable and appropriate systems for the treatment of organic wastewaters. Lettinga et al (1987) stated, "A satisfactory application to raw domestic sewage would represent ... -
Hydrothermal vent fields and chemosynthetic biota on the world's deepest seafloor spreading centre
(Springer Nature, 2012-01-10)The Mid-Cayman spreading centre is an ultraslow-spreading ridge in the Caribbean Sea. Its extreme depth and geographic isolation from other mid-ocean ridges offer insights into the effects of pressure on hydrothermal ... -
Hydroxycinnamic acid amide derivatives of polyamines reverse spermine-induced CNS excitation
(Elsevier, 2015-03-28)The aim of this study was to examine the acute effect of a range of novel hydroxycinnamic acid derivatives of spermine on the development of spermine-induced CNS excitation and convulsions in female Laca mice, and to assess ... -
Hydroxymethylglutaryl-coa reductase inhibition with simvastatin in acute lung injury to reduce pulmonary dysfunction (harp-2) trial: study protocol for a randomized controlled trial
(Springer Nature, 2012-09-17)Background: Acute lung injury (ALI) is a common devastating clinical syndrome characterized by life-threatening respiratory failure requiring mechanical ventilation and multiple organ failure. There are in vitro, animal ... -
Hygroscopic and chemical characterisation of po valley aerosol
(Copernicus GmbH, 2014-02-12)Continental summer-time aerosol in the Italian Po Valley was characterised in terms of hygroscopic properties and the influence of chemical composition therein. Additionally, the ethanol affinity of particles was analysed. ... -
Hygroscopicity of marine aerosol: Closure, long term observation and cloud condensation potential
(NUI Galway, 2021-09-18)Marine aerosols have a profound impact on the global climate system by scattering solar radiation and serving as seeds for cloud formation. However, the marine aerosols in current models are still poorly represented and ... -
Hygrothermal deterioration in carbon/epoxy and glass/epoxy composite laminates aged in marine-based environment (degradation mechanism, mechanical and physicochemical properties)
(Springer, 2022-01-27)One of the major challenges in off-shore tidal and wave energy devices is the ageing of these structures in the hostile marine environment, which limits their operating life. In this research, mechanical properties of aged ... -
A hyperbolic framework for shear sound beams in nonlinear solids
(Elsevier, 2021-09-14)In soft elastic solids, directional shear waves are in general governed by coupled nonlinear KZK-type equations for the two transverse velocity components, when both quadratic nonlinearity and cubic nonlinearity are taken ... -
Hyperbranched PEGmethacrylate linear pDMAEMA block copolymer as an efficient non-viral gene delivery vector
(Elsevier, 2012-06-02)A unique hyperbranched polymeric system with a linear poly-2-dimethylaminoethyl methacrylate (pDMAEMA) block and a hyperbranched polyethylene glycol methyl ether methacrylate (PEGMEMA) and ethylene dimethacrylate (EGDMA) ... -

Hypercapnia and acidosis in sepsis
(Ovid Technologies (Wolters Kluwer Health), 2010-02-01)Acute respiratory distress syndrome is a devastating disease that causes substantial morbidity and mortality. Mechanical ventilation can worsen lung injury, whereas ventilatory strategies that reduce lung stretch, resulting ... -
Hypercapnia induces cleavage and nuclear localization of relb protein, giving insight into co2sensing and signaling
(American Society for Biochemistry & Molecular Biology (ASBMB), 2012-03-06)Carbon dioxide (CO2) is increasingly being appreciated as an intracellular signaling molecule that affects inflammatory and immune responses. Elevated arterial CO2 (hypercapnia) is encountered in a range of clinical ... -
Hypercapnic acidosis attenuates lung injury induced by established bacterial pneumonia
(Ovid Technologies (Wolters Kluwer Health), 2008-11-01)Background: Hypercapnic acidosis protects against lung injury after ischemia-reperfusion, endotoxin-induced and ventilation-induced lung injury. The effects of hypercapnic acidosis in the setting of established pulmonary ... -
Hypercapnic acidosis attenuates pulmonary epithelial wound repair by an nf- b dependent mechanism
(BMJ, 2009-07-16)Background: Hypercapnic acidosis exerts protective effects in acute lung injury but may also slow cellular repair. These effects may be mediated via inhibition of nuclear factor-kappa B (NF-kappa B), a pivotal transcriptional ... -
