title: Dynamic metrics influence on the assessment of daylighting potential use at tropic climate

description: Abstract This paper aims to discuss the dynamic metrics Maximum Daylight Autonomy (DAmax) and Useful Daylight Illuminance (UDI) in daylight performance analysi in a tropical climate. Due to the high luminosity in the tropics, the results of these metrics may not provide adequate indications of uniformity and daylight availability in the room. Dynamic simulations were performed in Daysim software of a multipurpose room with a shaded fenestration system. The models combined visible sky factor (VSF high, medium and low) and window-to-wall ratio (WWR 20%, 40%, 60% and 90%), and were analyzed for three situations of minimum illuminance: 100 lux, 300 lux e 500 lux. Spreadsheets were used to customize the UDI and DAmax criteria. DAmax metrics for 100 lux, 300 lux, 500 lux, and three UDI intervals (100-2000 lux, 300-3.000 lux and 500-5.000 lux) were considered, comparing the conventional results with DAmax and UDI proposed by the spreadsheet. The results showed that conventional UDI and DAmax disregard significant occurrences of useful daylight in situations of high luminosity. The study contributes with proposed intervals of UDI and DAmax that showed more coherence in the analysis of luminous performance in the tropics.

title: Identifying occupant behaviour profiles for multifamily residential buildings with natural ventilation in Florianópolis

description: Abstract Interactions between occupant and built environment define the occupant behaviour. This set of information is essential for improving results obtained from computer simulations, since occupant behaviour influences building thermal and energetic performance. In this study, the influence of the occupant behaviour on the thermal performance of a building was analysed through computer simulations implemented with data of occupancy, window and blind control. Occupant behaviour profiles were identified by means of cluster analysis based on data obtained from monitoring naturally-ventilated multifamily residential buildings in Florianópolis. Different occupant behaviours were responsible for up to 130% of variations on results of degree hours for cooling and degree hours for heating. In general, occupancy was the aspect of occupant behaviour with more influence on the thermal performance due to the increase in internal thermal load and its association with control of building elements, determining a time dependence (routine).

title: PHOTODYNAMIC ACTIVITY AND CONCEPTS: A DEMONSTRATIVE EXPERIMENT

description: A simple and low cost experiment is proposed to chemistry students associating the Photodynamic Activity involving Chemical and Biochemical concepts. The inclusion of this experiment in undergraduate courses in Chemistry promotes interdisciplinarity and contextualization, combining current and relevant topics to the teaching of program content. The experiment used the Methylene Blue and Erythrosine B as dyes to demonstrate the photodynamic action of these photosensitizers in the inhibition of microbial growth. Both dyes presented satisfactory results against environmental microorganisms. The growth inhibition was caused exclusively by the photochemical processes undergone by the dye/light/oxygen, with LED light exposure.

title: Correlational study between daylighting configurations and light and thermal perception in a climate chamber

description: Abstract Human interactions in the built environment are mediated by physiological and psychological stimuli, which may interfere in the perception of environmental comfort variables. In this context, the degree of correlation between different ambient lighting configurations in terms of subjective thermal and light perception was evaluated. Tests were carried out in a rotating climatic chamber, located in Karlsruhe, Germany (49ºN, 8,5ºE). 16 subjects remained under controlled thermal conditions (PMV ± 0.5) over 5 h (8:00 a.m. to 1:00 p.m. local time) during three seasons in 2015, totalizing nine days of collection per individual, with 36 experimental sessions in total. Objective variables were assessed with spectroradiometers and comfort meters. Subjective perception of lighting characteristics and thermal comfort was obtained from questionnaires. Illuminance (E-lux), apparent color temperature (TCC-K), dominant wavelength (DWl-nm), and circadian action factor (acv) were correlated statistically (Spearman, rs) with objective environmental data: for the whole sample and for the group of individuals with indifferent chronotype (n = 11). Significant correlations were observed only between temperature perception and environmental variables in situations with less available natural light (winter, non equatorial façade) for the two groups evaluated, and the correlations were higher for the indifferent chronotype group.

title: Increase in pea productivity associated with irrigation management

description: ABSTRACT Proper irrigation management is crucial to obtain high yields of pea, since its cultivation is recommended in cold and dry seasons. Taking into account the great genetic diversity, we considered necessary to evaluate cultivars which best adapt to the intrinsic conditions of Cerrado Region, as it presents low fertility soil, long dry period in the winter, drought periods (veranicos) in rainy season, mainly in January and February (summer). Thus, the aim of this study was to evaluate adaptability of green-pea cultivars under different irrigation depths in Northeast Region of state of Mato Grosso do Sul. The experiment was installed in a split plot scheme, with four irrigation depths [50, 75, 100 and 125% of crop evapotranspiration (ETc)] and at subplots, four pea cultivars (Forró, Frevo, Pagode and Samba) in a randomized block design with three replications. Pod length, number and mass of grains per pod, number of pods per plant, plant length, productivity and efficiency of water use were evaluated. Excess water supply (water stress) or shortage (water deficit) can cause decrease in the productivity of pea crop for green grains, considering replacement of 114.81% of Etc, the most recommended for the crop. Cultivar Forró, showed the best productive performance in relation to other cultivars, in the climatic conditions of Southern Cerrado (Mato Grosso do Sul, Brazil).

title: Reaction of Capsicum peppers commercialized in the Federal District to bacterial wilt

description: ABSTRACT In Brazil, the bacterial pathogens Ralstonia solanacearum and R. pseudosolanacearum cause substantial losses by inducing bacterial wilt on several solanaceous crops; R. pseudosolanacearum is the main species associated with peppers (Capsicum sp.). To verify the bacterial wilt reaction on Capsicum peppers commercialized in the Federal District (DF), fruits of several genotypes within this genus were collected from six different fairs distributed in the satellite cities of Gama, Sobradinho and Guará. Seedlings with four true leaves derived from seeds extracted from such fruits were root inoculated with 108 CFU/mL with a representative isolate of R. pseudosolanacearum (race 1, biovar 3, phylotype I, sequevar 18). The evaluated species were: Capsicum frutescens (‘pimenta-malagueta’), Capsicum baccatum var. pendulum (‘pimenta-dedo-de-moça’) and C. chinense (‘pimenta-de-bode’ red and yellow, ‘pimenta-cumarí-do-Pará’, ‘pimenta-biquinho’, ‘pimenta-habanero’ and ‘pimenta-de-cheiro’). Not all species were found in all six fairs. The reaction to bacterial wilt was variable and species-dependent. From 26 evaluated genotypes, none presented an immune-like response, 10 were considered resistant and 16 susceptible based on wilt incidence (Scott-Knott, 5%). Four Capsicum baccatum accesses were positioned in the resistant group, whereas 14 out of 18 of C. chinense were susceptible. Capsicum frutescens showed variable reactions. These results contribute to indicate cultivation of specific groups of pepper according to the presence of the pathogen in the soil.

title: Selection of processing tomato genotypes resistant to two spotted spider mite

description: ABSTRACT One of the major problems in cultivation of tomato is the occurrence of pests and diseases. The objective of the research was to select genotypes from the second generation of the first backcross (F2BC1) between the tomato cultivar for processing S. lycopersicum (cv. Redenção) and the wild access S. habrochaites var. hirsutum (PI-127826), with high levels of zingiberene (ZGB), resistant to the twospotted spider mite Tetranychus urticae (Acari: Tetranychidae). From the F2BC1 population. The ZGB content was quantified and five plants with high zingiberene selected (RVTZ 2011-079-117, RVTZ 2011-079-185, RVTZ 2011-079-335, RVTZ 2011-079-345 and RVTZ 2011-079-503) and four with low zingiberene content (RVTZ 2011-079-417, RVTZ 2011-331-460, RVTZ 2011-079-538 and RVTZ 2011-079-548) were selected. Genotypes selected for high and low ZGB content and the parentals S. habrochaites var. hirsutum access PI-127826 and ‘Redenção’ were evaluated for repellency to the twospotted spider mite. There was a significant and inverse correlation between ZGB content and average distances travelled by mites on tomato leaflets. The genotypes of the F2BC1 generation with high zingiberene levels RVTZ 2011-079-117, RVTZ 2011-079-185, RVTZ 2011-079-335, RVTZ 2011-079-345 and RVTZ 2011-079-503 are promising for progress in achieving resistant lines to arthropod pests. Among them RVTZ 2011-079-117 stands out for resistance to twospotted spider mite.

title: Study of the chemical interaction between a high-viscosity glass ionomer cement and dentin

description: Abstract Objective To investigate the chemical interactions between a high-viscosity glass ionomer cement (GIC) (KetacTM Molar Easymix, 3M ESPE, Seefeld, Bavaria, Germany) and human dentin. It was also analyzed the dynamics of GIC setting mechanism based on the time intervals required for the GIC and the GIC mixed with dentin to achieve stability. Material and Methods Each constituent of GIC – powder (P) and liquid (L) – and powdered dentin (D), as well as the associations P+L, D+L, and P+L+D in the concentrations of 29%, 50%, 65%, 78%, 82%, and 92% of GIC were analyzed with Fourier transform infrared (FTIR) and Raman spectroscopy. Results New optical absorption bands and/or Raman bands, which were not present in P, L, or D, were observed in the associations. The concentrations of 29% and 50% of GIC showed higher interaction, revealing that the amount of dentin influences the formation of new optical absorption or scattering bands. FTIR bands showed that the setting time to achieve bond stability was longer for the high-viscosity GIC (38±7 min) than for the sample with 29% of GIC (28±4 min). Conclusions The analysis revealed the formation of new compounds or molecular rearrangements resulting from the chemical interactions between GIC and dentin. Moreover, this study provides an effective method to evaluate the dynamics of the setting mechanism of GICs.

title: Effects of diode laser application on inflammation and mpo in periodontal tissues in a rat model

description: Abstract Objective In this study, we aimed to histologically and immunologically evaluate the effect of diode laser treatment when applied adjunctive to scaling and root planing (SRP) in an experimental periodontitis model. Materials and methods We used Wistar-Albino rats (n=60) with average weight of 230 g. Experimental periodontitis was induced by ligature at the right and left first mandibular molar teeth in all rats. After 11 days, the ligature was removed and rats were divided into two groups. The control group (n=30) received only SRP treatment, while the laser group (n=30) received a diode laser (GaAlAs, 810 nm, 1 W, 10 J, 20 s) treatment adjunctive to SRP. Ten rats in each group were sacrificed after 7, 15, and 30 days. Histopathological examination was performed in the left mandible of rats. Myeloperoxidase (MPO) was evaluated by western blot in the gingival specimens from the right mandible. Results MPO levels in the laser group were statistically significantly lower compared with the control group (p≤0.05). There was no statistically significance at any time between MPO levels in the control group (p&gt;0.05). MPO levels in the laser group at the 7th day were statistically significantly higher compared to the 15th (p≤0.05) and the 30th day (p≤0.05). Inflammatory cell infiltration decreased over time in both groups and was statistically significantly lower in the laser group than in the control group at all times (p≤0.01). Conclusions Within the limits of this study, we suggest that diode laser application is an adjunctive treatment because it reduced inflammation and MPO when applied in addition to SRP. On the other hand, more studies are needed for the assessment of the effects of diode laser application to periodontal tissues.
