Characterising the marine Natura 2000 network for the Atlantic region
(John Wiley & Sons, Ltd., 2008)1. One of the goals for Natura 2000, a key European Community programme of nature conservation, is to produce a network of protected areas. An analysis of the Natura 2000 marine sites proposed in the most recently agreed ... -
Characteristic classes of complexified bundles
(Summer School in Algebraic Topology: Sheaf theoretic methods in the theory of characteristic classes, 2007)We examine the topological characteristic cohomology classes of complexified vector bundles . In particular, all the classes coming from real vector bundles are computed. We use characteristic classes with the ax-ioms of ... -
Characteristics of black carbon aerosol during the chinese lunar year and weekdays in xi’an, china
(MDPI AG, 2015-02-05)Black carbon (BC) aerosol plays an important role in climate forcing. The net radiative effect is strongly dependent on the physical properties of BC particles. A single particle soot photometer and a carbon monoxide ... -

Characteristics of the association between the marine copepod, gastrodelphys clausii, and its fanworm host bispira volutacornis
(Springer Nature, 2005-10-08)Characteristics of the association of the marine copepod Gastrodelphys clausii with its fanworm host Bispira volutacornis were investigated from October 1997 to August 1999. Of the 982 hosts examined, 22.6% were infected, ... -
Characteristics, quality features and dynamics in formal youth mentoring relationships: The Rhodes model revisited
(Institute of Psychology in Academia, Czech Academy of Sciences, 2020-05-01)Youth mentoring interventions are based on one-to-one long-term mentoring relationships formed between a volunteer and socially disadvantaged children and young people, and operate also in the Czech Republic. The paper ... -
Characterization and intercomparison of aerosol absorption photometers: result of two intercomparison workshops
(Copernicus GmbH, 2011-02-10)Absorption photometers for real time application have been available since the 1980s, but the use of filter-based instruments to derive information on aerosol properties (absorption coefficient and black carbon, BC) is ... -
Characterization and reactivity of charcoal from high temperature pyrolysis (800–1600 °C)
(Elsevier, 2018-09-22)This study presents the effect of wood origin and heat treatment temperature on the CO2 reactivity, nanostructure and carbon chemistry of chars prepared at 800, 1200, and 1600 °C in slow pyrolysis reactors. The ... -
Characterization and reactivity of soot from fast pyrolysis of lignocellulosic compounds and monolignols
(Elsevier, 2018-02-06)This study presents the effect of lignocellulosic compounds and monolignols on the yield, nanostructure and reactivity of soot generated at 1250 C in a drop tube furnace. The structure of soot was characterized by electron ... -
Characterization and seasonal variations of levoglucosan in fine particulate matter in xi’an, china
(Informa UK Limited, 2014-10-20)PM2.5 (particulate matter with an aerodynamic diameter <2.5 mu m) samples (n = 58) collected every sixth day in Xi'an, China, from 5 July 2008 to 27 June 2009 are analyzed for levoglucosan (1,6-anhydro-beta-d-glucopyranose) ... -
Characterization of a Crustal Transition Zone in Northern Tibet using Magnetotelluric Modelling
