Resilience of green roofs to climate change

The successful management of cities growth rely in part on the maximization of the benefits delivered by the built environment while minimizing the environmental degradation. Circular and resourceful cites are the mainstream for climate change resilience. Green roofs, as a nature-based solution, contribute to climate change adaptation and mitigation through the provision of several ecosystem services. Value of green roofs can be achieved at the level of environmental (e.g., air quality enhancement, carbon sequestration, biodiversity promotion stormwater management, acoustic insulation, and noise reduction), social (e.g., esthetic integration, well-being and life quality, rooftop gardens), and economic (e.g., life span extension, energetic efficiency, energy production, real-state valorization, business development) spheres. Buildup green roof resilience maybe underpinned by the selection of efficient and sustainable components for its installation. This chapter aims at giving an overview on the role of green roofs resilience to climate change, highlighting the provision of services and the mitigation and adaption capacity.info:eu-repo/semantics/acceptedVersio

Ensaio sobre a eficácia de um produto biológico no tratamento da varroose

Este estudo teve como objectivo avaliar a eficácia de um produto biológico "Gavarra", formulado à base de extractos de plantas (Eucaliptos globulus e Thymus vu/garis}, no tratamento da Varroase. Foi utilizado um produto químico como tratamento de controlo (Apistan®), que permitiu conhecer o grau inicial de infestação das colónias e, posteriormente foram efectuadas várias contagens do número médio de ácaros mortos, após cada aplicação do produto biológico. Para identificar diferenças estatisticamente significativas entre alguns parâmetros, efectuaram-se análises de variância segundo o teste de BONFERRONIIDUNN (DUNN, 1961 ). O número médio de ácaros mortos entre o tratamento de controlo e o primeiro tratamento com o produto biológico foi igual (P>0,05), diminuindo gradualmente nas consecutivas aplicações. Porém, apenas a média de ácaros caídos por colmeia com o tratamento biológico na 6a e 7a aplicação diferiu de uma forma estatisticamente significativa (P:s;0,001) dos encontrados com a aplicação do produto de controlo. Aparentemente, o produto biológico "Gavarra" mostrou ter uma eficácia idêntica à do produto de controlo no tratamento desta doença

Anadenanthera colubrina vell brenan : anti-candida and antibiofilm activities, toxicity and therapeutical action

We evaluated the antifungal and antibiofilm potential of the hydroalcoholic extract of bark from Anadenanthera colubrina (vell.) Brenan, known as Angico, against Candida spp. Antifungal activity was evaluated using the microdilution technique through the Minimum Inhibitory and Fungicide Concentrations (MIC and MFC). The antibiofilm potential was tested in mature biofilms formed by Candida species and analyzed through the counting of CFU/mL and scanning electron micrograph (SEM). In vivo toxicity and therapeutic action was evaluated in the Galleria mellonella model. The treatment with the extract, in low doses, was able to reduce the growth of planktonic cells of Candida species. MIC values range between 19.5 and 39 µg/mL and MFC values range between 79 and 625 µg/mL. In addition was able to reduce the number of CFU/mL in biofilms and to cause structural alteration and cellular destruction, observed via SEM. A. colubrina showed low toxicity in the in vivo assay, having not affected the viability of the larvae at doses below 100mg/kg and high potential in the treatment of C. albicans infection. Considering its high antifungal potential, its low toxicity and potential to treatment of infections in in vivo model, A. colubrina extract is a strong candidate for development of a new agent for the treatment of oral candidiasis33CONSELHO NACIONAL DE DESENVOLVIMENTO CIENTÍFICO E TECNOLÓGICO - CNPQ552562/2011-

Energy Expenditure In Vocalizations Of Pigs Under Stresses

Modern swine production faces many challenges nowadays, among which are productivity growth, meat quality improvement, decrease of environmental damage and reduction of cost production. Pigs spend energy to vocalizing, especially when they undergo stress. The waste of energy can increase the cost of production and lead to greater environmental damage. The goal of this study was to estimate the energy spent by pigs under the stress of castration and its effect on the animals' weight gain. Two groups of ten animals each were castrated, being one group with local anesthetic and the other without anesthetic. The piglets' vocalizations were recorded during different stages of the neutering process and then estimated of the amount of energy emitted during each vocalization. Afterwards, this energy was associated with the animals' weight gain. There was no difference in the total energy spent in both groups, since the energy used during the application of anesthetic was similar to the energy spent during the castration of the animals without anesthetic. There was also no correlation between energy spent and the animals' weight gain. It was possible to estimate the amount of energy emitted through vocalization. This energy spent by piglets in pain was greater than in other handling situations (contention, weighting and realease).335896901Cordeiro, A.F.S., Pereira, E.M., Nääs, I.A., Silva, W.T., Moura, D.J., Medida de Vocalização de Suínos (Sus scrofa) como um Indicador de Gasto Energético (2009), p. 2. , Brazilian Journal of Biosystems Engineering, CampinasCosta, A.N., Produção e bem-estar animal aspectos técnicos e éticos da produção intensiva de suínos (2008) Ciência Veterinária nos Trópicos, Recife 11, 1, pp. 43-48Costa, O.A.D., Ludke, J.V., Costa, M.J.R.P., Faucitano, L., Peloso, J.V., Roza, D.D., Modelo de carroceria e seu impacto sobre o bem-estar e a qualidade da carne dos suínos (2007) Ciência Rural, Santa Maria, 37 (5), pp. 1418-1422Dallanora, D., Machado, G.S., Biondo, N., Impacto da qualidade dos leitões desmamados sobre o desempenho posterior nas creches terminações (2010) Acta Scientiae Veterinariae, Porto Alegre, 37, pp. 171-180Hötzel, M.J., Machado Filho, L.C.P., (2013), pp. 34-38. , http://www.freewebs.com/hotzel/PorWorld2004.pdf, Comportamento e bem-estar dos leitões em relação ao desmame.

Induction of radiata pine somatic embryogenesis at high temperatures provokes a long-term decrease in dna methylation/hydroxymethylation and differential expression of stress-related genes

Based on the hypothesis that embryo development is a crucial stage for the formation of stable epigenetic marks that could modulate the behaviour of the resulting plants, in this study, radiata pine somatic embryogenesis was induced at high temperatures (23¿ C, eight weeks, control; 40¿ C, 4 h; 60¿ C, 5 min) and the global methylation and hydroxymethylation levels of emerging embryonal masses and somatic plants were analysed using LC-ESI-MS/ MS-MRM. In this context, the expression pattern of six genes previously described as stress-mediators was studied throughout the embryogenic process until plant level to assess whether the observed epigenetic changes could have provoked a sustained alteration of the transcriptome. Results indicated that the highest temperatures led to hypomethylation of both embryonal masses and somatic plants. Moreover, we detected for the first time in a pine species the presence of 5-hydroxymethylcytosine, and revealed its tissue specificity and potential involvement in heat-stress responses. Additionally, a heat shock protein-coding gene showed a down-regulation tendency along the process, with a special emphasis given to embryonal masses at first subculture and ex vitro somatic plants. Likewise, the transcripts of several proteins related with translation, oxidative stress response, and drought resilience were differentially expressed

Surface and electronic structure of MOCVD-grown Ga(0.92)In(0.08)N investigated by UV and X-ray photoelectron spectroscopies

The surface and electronic structure of MOCVD-grown layers of Ga(0.92)In(0.08)N have been investigated by means of photoemission. An additional feature at the valence band edge, which can be ascribed to the presence of In in the layer, has been revealed. A clean (0001)-(1x1) surface was prepared by argon ion sputtering and annealing. Stability of chemical composition of the investigated surface subjected to similar ion etching was proven by means of X-ray photoemission spectroscopy.Comment: 13 pages, 6 figure

Volumetric Capnography For The Evaluation Of Chronic Airways Diseases

Background: Obstructive lung diseases of different etiologies present with progressive peripheral airway involvement. The peripheral airways, known as the silent lung zone, are not adequately evaluated with conventional function tests. The principle of gas washout has been used to detect pulmonary ventilation inhomogeneity and to estimate the location of the underlying disease process. Volumetric capnography (VC) analyzes the pattern of CO2elimination as a function of expired volume.Objective: To measure normalized phase 3 slopes with VC in patients with non-cystic fibrosis bronchiectasis (NCB) and in bronchitic patients with chronic obstructive pulmonary disease (COPD) in order to compare the slopes obtained for the groups.Methods: NCB and severe COPD were enrolled sequentially from an outpatient clinic (Hospital of the State University of Campinas). A control group was established for the NCB group, paired by sex and age. All subjects performed spirometry, VC, and the 6-Minute Walk Test (6MWT). Two comparisons were made: NCB group versus its control group, and NCB group versus COPD group. The project was approved by the ethical committee of the institution. Statistical tests used were Wilcoxon or Student’s t-test; P,0.05 was considered to be a statistically significant difference.Results: Concerning the NCB group (N=20) versus the control group (N=20), significant differences were found in body mass index and in several functional variables (spirometric, VC, 6MWT) with worse results observed in the NCB group. In the comparison between the COPD group (N=20) versus the NCB group, although patients with COPD had worse spirometric and 6MWT values, the capnographic variables mean phase 2 slope (Slp2), mean phase 3 slope normalized by the mean expiratory volume, or mean phase 3 slope normalized by the end-tidal CO2concentration were similar.Conclusion: These findings may indicate that the gas elimination curves are not sensitive enough to monitor the severity of structural abnormalities. The role of normalized phase 3 slope may be worth exploring as a more sensitive index of small airway disease, even though it may not be equally sensitive in discriminating the severity of the alterations.9983989Robinson, P.D., Goldman, M.D., Gustafsson, P.M., Inert gas washout: Theoretical background and clinical utility in respiratory disease (2009) Respiration, 78 (3), pp. 339-355Ribeiro, M., Silva, M.T., Ribeiro, J.D., Volumetric capnography as a tool to detect early peripheric lung obstruction in cystic fibrosis patients (2012) J Pediatr (Rio J), 88 (6), pp. 509-517Almeida, C.C., Almeida-Júnior, A.A., Ribeiro, M.A., Nolasco-Silva, M.T., Ribeiro, J.D., Volumetric capnography to detect ventilation inhomogeneity in children and adolescents with controlled persistent asthma (2011) J Pediatr (Rio J), 87 (2), pp. 163-168Veronez, L., Moreira, M.M., Soares, S.T., Volumetric capnography for the evaluation of pulmonary disease in adult patients with cystic fibrosis and noncystic fibrosis bronchiectasis (2010) Lung, 188 (3), pp. 263-268Moreira, M.M., Terzi, R.G., Carvalho, C.H., de Oliveira Neto, A.F., Pereira, M.C., Paschoal, I.A., Alveolar dead space and capnographic variables before and after thrombolysis in patients with acute pulmonary embolism (2009) Vasc Health Risk Manag, 5 (1), pp. 9-12Moreira, M.M., Terzi, R.G., Paschoal, I.A., Martins, L.C., Oliveira, E.P., Falcão, A.L., Thrombolysis in massive pulmonary embolism based on the volumetric capnography (2010) Arq Bras Cardiol, 95 (4), pp. e97-e99Pereira, D.J., Moreira, M.M., Paschoal, I.A., Martins, L.C., Metze, K., Moreno Junior, H., Near-fatal pulmonary embolism in an experimental model: Hemodynamic, gasometric and capnographic variables (2011) Rev Bras Cir Cardiovasc, 26 (3), pp. 462-468Schwardt, J.D., Gobran, S.R., Neufeld, G.R., Aukburg, S.J., Scherer, P.W., Sensitivity of CO2 washout to changes in acinar structure in a single-path model of lung airways (1991) Ann Biomed Eng, 19 (6), pp. 679-697Schreiner, M.S., Leksell, L.G., Gobran, S.R., Hoffman, E.A., Scherer, P.W., Neufeld, G.R., Microemboli reduce phase III slopes of CO2 and invert phase III slopes of infused SF6 (1993) Respir Physiol, 91 (2-3), pp. 137-154Vestbo, J., Hurd, S.S., Agustí, A.G., Global strategy for the diagnosis, management, and prevention of chronic obstructive pulmonary disease: GOLD executive summary (2013) Am J Respir Crit Care Med, 187 (4), pp. 347-365ATS statement: Guidelines for the six-minute walk test (2002) Am J Respir Crit Care Med, 166 (1), pp. 111-117. , ATS Committee on Proficiency Standards for Clinical Pulmonary Function LaboratoriesPréfaut, C., Durand, F., Mucci, P., Caillaud, C., Exercise-induced arterial hypoxaemia in athletes: A review (2000) Sports Med, 30 (1), pp. 47-61Pereira, C.A., Sato, T., Rodrigues, S.C., New reference values for forced spirometry in white adults in Brazil (2007) J Bras Pneumol, 33 (4), pp. 397-406Cosio, M., Ghezzo, H., Hogg, J.C., The relations between structural changes in small airways and pulmonary-function tests (1978) N Engl J Med, 298 (23), pp. 1277-1281Stănescu, D.C., Rodenstein, D.O., Hoeven, C., Robert A. “Sensitive tests” are poor predictors of the decline in forced expiratory volume in one second in middle-aged smokers (1987) Am Rev Respir Dis, 135 (3), pp. 585-590Buist, A.S., Vollmer, W.M., Johnson, L.R., McCamant, L.E., Does the single-breath N2 test identify the smoker who will develop chronic airflow limitation?
