Plant growth and leaf-spot severity on eucalypt at different CO2concentrations in the air

The objective of this work was to evaluate the effects of increased air-CO2 concentration on plant growth and on leaf-spot caused by Cylindrocladium candelabrumin Eucalyptus urophylla. Seedlings were cultivated for 30 days at 451, 645, 904, and 1,147 µmol mol-1 CO2 ; then, they were inoculated with the pathogen and kept under the same conditions for seven days. Increased CO2concentration increased plant height and shoot dry matter mass, and decreased disease incidence and severity. Stem diameter was not affected by the treatments. Increased concentrations of atmospheric CO2 favorably affect eucalypt growth and reduce leaf-spot severity.

A segmentation analysis and segments profile of budget air travelers

Many Spanish destinations are now considering low cost airlines (LCA) important for attracting tourists. However, there is little evidence on the characteristics travelers using low cost airlines and their flight preferences. Typical segmentation of air travelers are business versus leisure travelers and business versus tourist fares. The aim of this paper is to obtain a deeper understanding of the demand of LCA through a segmentation analysis, based on 808 foreign travelers who used Girona airport, that focuses on low cost travelers’ valuations of different flight attributes and trip related characteristics

Endovascular treatment of symptomatic intracranial arterial stenosis: six-year experience in a single-center series of 42 consecutive patients with acute and mid-term results.

BACKGROUND: The limitations of the medical management of symptomatic intracranial arterial stenosis encourage the development of new therapeutic strategies such as intracranial stenting. OBJECTIVE: To report and analyze the results of a series of 42 patients treated with 3 different endovascular techniques: isolated angioplasty, balloon-expandable coronary stents, and the Wingspan self-expandable intracranial stent system. METHODS: Forty-two patients presenting with symptomatic intracranial arterial stenosis were treated with one of these techniques. Computed tomography angiography was performed 6 months after the procedure, and the clinical neurological statuses were categorized using the modified Rankin Scale and the National Institutes of Health Stroke Scale. RESULTS: A total of 42 lesions were treated: 9 with isolated angioplasty, 14 with balloon-expandable coronary stents, and 19 with Wingspan self-expandable intracranial stents. The mean patient age was 62.9 years, and the mean arterial diameter stenosis was 73.9%. Technical success was achieved in 97.6% of the patients. The overall incidence of procedural complications was 21.4%, and the postoperative permanent morbidity/mortality rate was 7.1%. There were 3 cases of in-stent thrombosis (1 fatal) and 5 cases of asymptomatic restenosis (11.9%), 3 in the isolated angioplasty group and 2 in the Wingspan self-expandable intracranial stent group (mean follow-up 20.4 months). The rate of restenosis was higher in the angioplasty group (33%) than in the coronary (0%) and Wingspan stent (10.5%) groups. CONCLUSION: Endovascular treatment of symptomatic intracranial stenosis has significant overall morbidity and mortality rates. Nevertheless, the very critical natural history of severe refractory lesions and the relatively favorable postoperative evolution suggest that it should be considered the first alternative strategy in cases in which medical therapy has failed.

Graphitized carbon black in quartz tubes for the sampling of indoor air nicotine and analysis by microwave thermal desorption-capillary gas chromatography

Nicotine in a smoky indoor air environment can be determined using graphitized carbon black as a solid sorbent in quartz tubes. The temperature stability, high purity, and heat absorption characteristics of the sorbent, as well as the permeability of the quartz tubes to microwaves, enable the thermal desorption by means of microwaves after active sampling. Permeation and dynamic dilution procedures for the generation of nicotine in the vapor phase at low and high concentrations are used to evaluate the performances of the sampler. Tube preparation is described and the microwave desorption temperature is measured. Breakthrough volume is determined to allow sampling at 0.1-1 L/min for definite periods of time. The procedure is tested for the determination of gas and paticulate phase nicotine in sidestream smoke produced in an experimental chamber.

Lämmönlähteiden aiheuttamien konvektiovirtausten vaikutus vastakkaiseen tuloilmasuihkuun

Huoneen sisäisten lämpölähteiden aiheuttamilla konvektiovirtauksilla eli pluumeilla on huomattava vaikutus ilmastointipalkkijärjestelmäntoimintaan. Tätä vaikutusta ei ole tutkittu kovin paljon. Tässä työssä tutkittiin huoneen päätyseinässä olevan sähkölämmityspatterin vaikutusta aktiivisen ilmastointipalkin toimintaan. Tutkimus kohdistui vastakkaisten suihkujen törmäykseen. Suihkuina olivat pluumit ja tuloilmavirtaus. Tutkimukseen kuului sekä teoreettinen että kokeellinen osio. Teoreettisessa tarkastelussa käytiin läpi ilmastointipalkin teoriaa sekä konvektiovirtausten muodostumisen teoriaa. Lisäksi esitettiin, kuinka suihkuista lasketaan liikemäärävirta. Kokeellisessa osiossa mitattiin huoneen sisäisten lämpölähteiden aiheuttamia pluumeja. Lämpölähteet oli sijoitettuina tutkimushuoneen päätyseinän viereen. Mittauksissa keskityttiin tarkemmin sähkölämmityspatteriin ja sitä mallinnettiin eri tehoilla. Lisäksi mitattiin ilmastointipalkin tuloilmavirtausta eri ilmamäärillä. Pluumien ja tuloilmavirtauksen törmäyskäyttäytymistä selvitettiin savukuvauksella. Analyysiosiossa sähkölämmityspatterin aiheuttaman pluumin ja palkin tuloilmavirtauksen törmäyskäyttäytymiselle kehitettiin malli. Mallissa huomioitiin vastaikkaisten törmäävien suihkujen liikemäärät ja esitettiin kohdat tutkimushuoneen pituussuunnassa, jossa tuloilmavirtaus kääntyy oleskeluvyöhykkeelle. Ilmastointipalkkijärjestelmässä tuloilmavirtauksen tulisi kääntyä oleskeluvyöhykkeelle vasta huoneen seinustalla. Tutkimuksen perusteella näin käy, jos pluumin liikemäärä on noin 10% tai vähemmän tuloilman liikemäärästä. Muulloin palkin tuloilmavirtaus kääntyy oleskeluvyöhykkeelle liian aikaisin ja aiheuttaa mahdollisestivedontunnetta.

Settlement evolution, field systems and sedimentary processes in a Mediterranean mid-mountain (Montseny Massif, Catalunya)

This paper presents the first results of a current research project about human – environmental interactions in the Montseny Massif. Our work sets out to integrate two research lines in the studied area: - Archaeological and archaeo-morphological surveys in a lower part of the mountains in order to characterize the evolution of the settlements and field systems. - The geological and geomorphological characterization of the slope and terrace deposits in relation with field systems and archaeological data. First results point out the intensive occupation of these inland areas during the Iberian and the Roman periods. Post-Roman sediments show different processes of erosion.

Practical applications of a systematic approach to the chemical abatement of pollutants in water and air

The present dissertation is devoted to the systematic approach to the development of organic toxic and refractory pollutants abatement by chemical decomposition methods in aqueous and gaseous phases. The systematic approach outlines the basic scenario of chemical decomposition process applications with a step-by-step approximation to the most effective result with a predictable outcome for the full-scale application, confirmed by successful experience. The strategy includes the following steps: chemistry studies, reaction kinetic studies in interaction with the mass transfer processes under conditions of different control parameters, contact equipment design and studies, mathematical description of the process for its modelling and simulation, processes integration into treatment technology and its optimisation, and the treatment plant design. The main idea of the systematic approach for oxidation process introduction consists of a search for the most effective combination between the chemical reaction and the treatment device, in which the reaction is supposed to take place. Under this strategy,a knowledge of the reaction pathways, its products, stoichiometry and kinetics is fundamental and, unfortunately, often unavailable from the preliminary knowledge. Therefore, research made in chemistry on novel treatment methods, comprisesnowadays a substantial part of the efforts. Chemical decomposition methods in the aqueous phase include oxidation by ozonation, ozone-associated methods (O3/H2O2, O3/UV, O3/TiO2), Fenton reagent (H2O2/Fe2+/3+) and photocatalytic oxidation (PCO). In the gaseous phase, PCO and catalytic hydrolysis over zero valent ironsare developed. The experimental studies within the described methodology involve aqueous phase oxidation of natural organic matter (NOM) of potable water, phenolic and aromatic amino compounds, ethylene glycol and its derivatives as de-icing agents, and oxygenated motor fuel additives ¿ methyl tert-butyl ether (MTBE) ¿ in leachates and polluted groundwater. Gas-phase chemical decomposition includes PCO of volatile organic compounds and dechlorination of chlorinated methane derivatives. The results of the research summarised here are presented in fifteenattachments (publications and papers submitted for publication and under preparation).
