Recycled asphalt mixtures produced with high percentage of different waste materials

The use of sustainable solutions in construction is not just an option, but is increasingly becoming a need of the Society. Thus, nowadays the recycling of waste materials is a growing technology that needs to be continuously improved, namely by researching new solutions for waste valorisation and by increasing the amount of wastes reused. In the paving industry, the reuse of reclaimed asphalt (RA) is becoming common practice, but needs further research work. Thus, this study aims to increase the incorporation of RA and other waste materials in the production of recycled asphalt mixtures in order to improve their mechanical, environmental and economic performance. Recycled mixtures with 50% RA were analysed in this study, including: i) RA selection, preparation and characterization; ii) incorporation of other waste materials as binder additives or modifiers, like used motor oil (UMO) and waste high density polyethylene (HDPE); iii) production of different mixtures (without additives; with UMO; with UMO and HDPE) and comparison of their performance in order to assess the main advantages of each solution. With this study it was concluded that up to 7.5 % of UMO and 4.0 % of HDPE can be used in a new modified binder for asphalt mixtures with 50 % of RA, which have excellent properties concerning the rutting with WTS = 0.02 mm/103 cycles, the fatigue resistance with ε6 = 160.4, and water sensitivity with an ITSR of 81.9 %.

Green furniture: sustainable design guidelines for the Irish furniture and wood products industry.

This thesis presents the research and development of sustainable design guidelines for the furniture and wood products industry, suitable for sustainably enhancing design, manufacturing and associated activities. This sustainable guideline is based on secondary research conducted on subject areas such as ‘eco’ design, ‘green’ branding and ‘green’ consumerism, as well as an examination of existing certifications and sustainable tools techniques and methodologies, national and international drivers for sustainable development and an overview of sustainability in the Irish furniture manufacturing context. The guideline was further developed through primary research. This consisted of a focus group attended by leading Irish designers, manufacturers and academics in the area of furniture and wood products. This group explored the question of ‘green branding’ saturation in the market and the viability of investing in sustainability just yet. Participants stated that they felt the market for ‘green’ products is evolving very slowly and that there is no metric or legal framework present to audit whether or not companies are producing products that really embody sustainability. All the participants believed that developing and introducing a new certification process to incorporate a sustainable design process was a viable and necessary solution to protecting Irish furniture and wood manufacturers going forward. For the purposes of the case study, the author investigated a ‘sustainable’ design process for Team woodcraft, Ltd., through the design and development of a ‘sustainable’ children’s furniture range. The case study followed a typical design and development process; detailing customer design specifications, concept development and refinement and cumulating in final prototype, as well as associated engineering drawings. Based on this primary and secondary research, seven fundamental core principles for this sustainable guideline have been identified by the author. The author then used these core principles to expand into guidelines for the basis of proposed new Irish sustainable design guidelines for the furniture and wood products industry, the concept of which the author has named ‘Green Dot’. The author suggests that the ‘Green Dot’ brand or logo could be used to market an umbrella network of Irish furniture designers and manufactures who implement the recommended sustainable techniques.

Subgroup analyses in randomised controlled trials: cohort study on trial protocols and journal publications

OBJECTIVE: To investigate the planning of subgroup analyses in protocols of randomised controlled trials and the agreement with corresponding full journal publications. DESIGN: Cohort of protocols of randomised controlled trial and subsequent full journal publications. SETTING: Six research ethics committees in Switzerland, Germany, and Canada. DATA SOURCES: 894 protocols of randomised controlled trial involving patients approved by participating research ethics committees between 2000 and 2003 and 515 subsequent full journal publications. RESULTS: Of 894 protocols of randomised controlled trials, 252 (28.2%) included one or more planned subgroup analyses. Of those, 17 (6.7%) provided a clear hypothesis for at least one subgroup analysis, 10 (4.0%) anticipated the direction of a subgroup effect, and 87 (34.5%) planned a statistical test for interaction. Industry sponsored trials more often planned subgroup analyses compared with investigator sponsored trials (195/551 (35.4%) v 57/343 (16.6%), P<0.001). Of 515 identified journal publications, 246 (47.8%) reported at least one subgroup analysis. In 81 (32.9%) of the 246 publications reporting subgroup analyses, authors stated that subgroup analyses were prespecified, but this was not supported by 28 (34.6%) corresponding protocols. In 86 publications, authors claimed a subgroup effect, but only 36 (41.9%) corresponding protocols reported a planned subgroup analysis. CONCLUSIONS: Subgroup analyses are insufficiently described in the protocols of randomised controlled trials submitted to research ethics committees, and investigators rarely specify the anticipated direction of subgroup effects. More than one third of statements in publications of randomised controlled trials about subgroup prespecification had no documentation in the corresponding protocols. Definitive judgments regarding credibility of claimed subgroup effects are not possible without access to protocols and analysis plans of randomised controlled trials.

Introduction d'un questionnaire de dépistage de l'Etat de stress post traumatique (ESPT) : quel impact sur le diagnostic dans une unité d'urgence psychiatrique ambulatoire ?

Contexte: Impression clinique que l'Etat de Stress Post-traumatique (ESPT) est sous-diagnostiqué dans la prise en charge des patients qui sont évalués dans le cadre d'une urgence psychiatrique. Objectifs: (i) identifier la prévalence de l'ESPT dans une unité d'urgence psychiatrique au moyen d'un instrument diagnostic et la comparer avec le diagnostic clinique retenu dans un échantillon historique (ii) évaluer la perception des cliniciens quant à l'utilisation systématique d'un instrument diagnostic Méthodes: la prévalence de l'ESPT a été évaluée chez des patients consécutifs (N = 403) qui ont bénéficié d'une consultation par des psychiatres de l'Unité urgence-crise du Service de Psychiatrie de Liaison (PLI) du CHUV, en utilisant le module J du Mini Mental Neuropsychologic Interview (MINI 5.0.0, version CIM-10). Ce résultat a été comparé avec la prévalence de l'ESPT mentionné comme diagnostic dans les dossiers (N = 350) d'un échantillon historique. La perception des médecins-assistants de psychiatrie quant au dépistage systématique de l'ESPT avec un instrument a été étudiée en se basant sur la conduite d'un focus group d'assistants travaillant dans l'Unité urgence-crise du PLI. Résultats: Parmi les patients (N = 316) évalués à l'aide de l'instrument diagnostic, 20,3% (n = 64) réunissaient les critères de l'ESPT. Cela constitue un taux de prévalence significativement plus élevé que la prévalence d'ESPT documentée dans les dossiers de l'échantillon historique (0,57%). Par ailleurs, la prévalence de l'ESPT est significativement plus élevée parmi les groupes socio- économiques précarisés, tels que réfugiés et sans papiers (50%), patients venant d'un pays à histoire de guerre récente (47,1%), patients avec quatre (44,4%) ou trois comorbidités psychiatriques (35,3%), migrants (29,8%) et patients sans revenus professionnels (25%). Le focus groupe composé de 8 médecins-assistants a révélé que l'utilisation systématique d'un outil- diagnostic ne convenait pas dans le setting d'urgence psychiatrique, notamment parce que l'instrument a été considéré comme non adapté à une première consultation ou jugé avoir un impact négatif sur l'entretien clinique. Toutefois, après la fin de l'étude, les médecins-assistants estimaient qu'il était important de rechercher activement l'ESPT et continuaient à intégrer les éléments principaux du questionnaire dans leur travail clinique. Conclusion et perspectives: cette étude confirme que l'ESPT est largement sous-diagnostiqué dans le contexte des urgences psychiatriques, mais que l'usage systématique d'un outil diagnostic dans ce cadre ne satisfait pas les praticiens concernés. Pour améliorer la situation et au vu du fait qu'un instrument diagnostic est considéré comme non-adapté dans ce setting, il serait peut-être bénéfique d'envisager un dépistage ciblé et/ou de mettre en place une stratégie de formation institutionnelle.

Origins of production errors and significance of employee empowerment in reducing production error amount in sheet metal fabricating industry

The market place of the twenty-first century will demand that manufacturing assumes a crucial role in a new competitive field. Two potential resources in the area of manufacturing are advanced manufacturing technology (AMT) and empowered employees. Surveys in Finland have shown the need to invest in the new AMT in the Finnish sheet metal industry in the 1990's. In this run the focus has been on hard technology and less attention is paid to the utilization of human resources. In manymanufacturing companies an appreciable portion of the profit within reach is wasted due to poor quality of planning and workmanship. The production flow production error distribution of the sheet metal part based constructions is inspectedin this thesis. The objective of the thesis is to analyze the origins of production errors in the production flow of sheet metal based constructions. Also the employee empowerment is investigated in theory and the meaning of the employee empowerment in reducing the overall production error amount is discussed in this thesis. This study is most relevant to the sheet metal part fabricating industrywhich produces sheet metal part based constructions for electronics and telecommunication industry. This study concentrates on the manufacturing function of a company and is based on a field study carried out in five Finnish case factories. In each studied case factory the most delicate work phases for production errors were detected. It can be assumed that most of the production errors are caused in manually operated work phases and in mass production work phases. However, no common theme in collected production error data for production error distribution in the production flow can be found. Most important finding was still that most of the production errors in each case factory studied belong to the 'human activity based errors-category'. This result indicates that most of the problemsin the production flow are related to employees or work organization. Development activities must therefore be focused to the development of employee skills orto the development of work organization. Employee empowerment gives the right tools and methods to achieve this.

Vesi-metanolitislauskolonnin ikääntyminen ja siihen vaikuttavat tekijät

Tässä työssä tutkittiin Fortum Oyj:n MTBE -yksikön vesi metanolitislauskolonnin käyttö- ja tarkastushistoriaa sekä yleisestä syöpymisestä aiheutunutta seinämän ohenemaa. Oheneminen oli kiihtynyt viimeisten käyttövuosien aikana. Kolonni poistettiin käytöstä vuonna 2002. Kirjallisuusosassa käsitellään MTBE -prosessia, metallien korroosiota eri olosuhteissa sekä korroosiotutkimusmenetelmiä. Eri korroosiotutkimusmenetelmistä käsitellään sähkökemiallinen kohina -menetelmää, vastuslankamittausta sekä upotuskokeita. Kokeellisessa osassa käsitellään tuloksia käyttö- ja tarkastushistoriaselvityksistä ja korroosiokokeista, jotka tehtiin kirjallisuusosassa esitettyjen menetelmien mukaisesti. Koekappaleet olivat hiiliterästä, joka oli vastaavaa materiaalia kuin metanolin tislauskolonni. Korroosiokokeiden tuloksista havaittiin, että hiiliteräs syöpyy nopeammin vesimetanoliliuoksessa, jossa on 60 - 80 metanolia. Syöpymisnopeus kasvoi liuoksen pH:n laskiessa ja oli suurinta kun pH oli alle 4,0.

Degradação eletroquímica da vinhaça usando eletrodo de diamante dopado com boro

The degradation of vinasses in aqueous solution from ethanol industry has been investigated by electrochemical oxidation using a boron doped diamond electrode (BDD). Samples of vinasses were electrolyzed in medium of (0.1 mol L-1) Na2SO4 solutions at controlled potentials of +2.4, +3.0 and +4.0 V (vs. Ag/AgCl) and exhibited considerable reduction of total organic carbon. The cyclic voltammetry studies indicate that the vinasses are oxidized irreversibly over the BDD at 2.0 V (vs. Ag/AgCl) in diffusion controlled process. From the experimental results it is clear that the BDD electrode can be a valuable tool to the electrochemical degradation of vinasses in practical applications

AVALIAÇÃO DO RADICAL N,N-DIETIL-1,4-FENILENODIAMINO (DEPD•+) COMO SONDA ESPECTROFOTOMÉTRICA PARA DETERMINAÇÃO DA CAPACIDADE ANTIOXIDANTE EM BEBIDAS

AbstractMany well-established methods for determining the antioxidant capacities in several samples have been described in literature. However, DPPH (2,2-diphenyl-1-picrylhydrazyl) and ABTS (2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid)) are the main two methods that utilize radicals as spectrophotometric probes for analysis. Nevertheless, these methods have certain limitations because of their slower kinetics, solvent polarity effects, the hydrophilicity and lipophilicity of the compounds, chemical costs, etc. In this study, a spectrophotometric method for determining the antioxidant capacity in beverages was developed based on an exploration of the cation radical derived from DEPD. This method was based on the oxidation of aromatic amines with Fe(III) ions at pH 4.0, which leads to their corresponding purple cation radicals (DEPD•+) with λmax values at 500 and 540 nm. The addition of an antioxidant after the formation of the radical leads to a reduction in color intensity that is proportional to the antioxidant concentration in the medium. Results obtained using this method were compared with the Folin-Ciocalteau, ABTS and DPPH methods in terms of applications in wines, teas, and infusions samples. Linear correlation analysis at a 95% confidence level was employed to compare the results, which were in good agreement with a correlation coefficient of r > 0.9000. Thus, the developed method was simple, accurate, and consistent with other assays for the determination of the total amount of phenolic compounds and antioxidant capacity.

Efeito de subdoses de 2,4-D na produtividade do algodão e suscetibilidade da cultura em função de seu estádio de desenvolvimento

O objetivo deste trabalho foi avaliar o efeito de subdoses de 2,4-D no desenvolvimento e produtividade da cultura do algodoeiro. Dois experimentos foram conduzidos utilizando-se da variedade IAPAR-95 e o sistema de avaliação por meio de testemunhas duplas. No primeiro experimento, as aplicações foram realizadas no estádio F1 (início do florescimento), aplicando-se dosagens de 0,84; 1,68; 3,36; 6,72; 13,44 e 26,88 g de equivalente ácido (e.a.) por hectare, equivalentes a derivas de 0,125; 0,25; 0,5; 1,0; 2,0 e 4,0% da dose de 670 g e.a. ha-1. No segundo experimento, os tratamentos foram constituídos pela combinação em esquema fatorial de duas doses (6,72 e 13,44 g e.a. ha-1) e três épocas de aplicação (C1, C3/C4 e C6), visando a avaliar a variação da sensibilidade do algodão ao 2,4-D em função de seu estádio de desenvolvimento. Os resultados evidenciaram que doses maiores que 3,36 g e.a. ha-1 (0,50%) aplicadas na fase de florescimento afetaram de forma significativa a produtividade, que a queda dos botões florais foi o sintoma mais importante para a redução da produtividade. No segundo experimento, observou-se que a sensibilidade do algodão caiu drasticamente em função do estádio de desenvolvimento. O único tratamento que provocou queda significativa de produtividade foi a dose de 13,44 g e.a. ha-1 (2,0%) aplicada no estádio C1. Dessa forma, a partir do momento em que as maçãs começam a se formar, a sensibilidade da cultura cai substancialmente.
