Full textSurface moisture plays an important role in thedeterioration of building surfaces. The extent and duration ofsurface moisture is generally impossible to predictfrommeteorological data and consequently direct measurement ofthis quantity is essential,e.g. using the WETCORR method. Thismethod has been developed in Scandinaviaduring the past 25years. From the beginning it was intended for measurementsofinstantaneous atmospheric corrosion rates and TOW (time ofwetness) using corrodingelectrolytic cells. Over the past 15years the method has been extended tomeasurements of surfacemoisture and TOW on building materials in general. To thatend amodified measuring concept has gradually been developed,including an inertelectrolytic cell with electrodes of gold(Au). More recently, the method has also been applied tomeasurements of moisture content (MC) in various materialsusingmodifications of the traditional pin-type electrodes.
This thesis summarises various measurement projects thathave involved theWETCORR method during the past 10 years. Someprojects are entirely focused on the method as such, some aremore concerned with the interaction between themoisture sensorand the environment. In some cases attempts are made tocorrelate TOW with corrosion.
The limitations of the ISO 9223 standard for estimating TOW(RH>80%, T>0°C) isclearly illustrated. Theshortcomings of the ISO standard become evident in climateswith sub-zero temperatures, in environments with significantdeposition of pollutantsand salt, and in situations where theexchange of radiation between building surfaces and thesurrounding environment creates large temperature differenceswhich in turnmay either promote or inhibit condensation.
A generalised definition of TOW based on the conductivity ofthe surface electrolyterather than the thickness of themoisture film is proposed. The modified TOW is called time ofconduction or time of corrosion, (TOC). Strict measurement ofTOC requiresthe use of an inert electrolytic sensor andexcitation by AC or pulsed DC withreversing of the polarity.This is different from the present WETCORR technique.Theadoption of the TOC concept opens up the possibility ofdividing time into "wet" and"dry" periods. This is believed tofacilitate for the development of dose-responsefunctions basedon the real physical/chemical processes occurring on materialsurfacesrather than on a parametric approach.
The WETCORR technique has proven to be very useful also formeasurements of MCin wood, a measurement concept called INWOOD.The general principles andtheoretical considerations for woodmoisture measurements are reviewed, includingthe derivation ofsemi-empirical relationships describing the dependence ofresistivity on MC, temperature and dry density of wood. Thesame technique should be possible to use with almost any porousbuilding material.

Full textThe objective of this work was to evaluate the influence of white polyethylene as a greenhouse cover and its association with different shading screens (thermal screen and black screen) on the following environmental elements: incoming solar radiation (Qg), photosynthetically active radiation (PAR), temperature (T), relative humidity (RH) and evapotranspiration (ET) and also to evaluate the effects of the different microclimatic conditions on the growth, development and quality of Gerbera Jamesonii. The experiment was carried out between late Autumn and Winter of 2002 at the experimental area of the Exact Sciences Departament, Agricultural College "Luiz de Queiroz", at the University of São Paulo, in Piracicaba, State of São Paulo, Brazil. A greenhouse was installed, sub-divided into three parts. One of them was covered just with white polyethylene (T1), while the others had, yet, shading screens, that were installed within the greenhouse, being one covered with a thermal screen (Alumitela) (T2) and the other one with a black screen (T3), both with 50% of shading, manufactured by Solpack Ltda. The meteorological sensors were installed in the center of each sub-division of the greenhouse and an automatic weather station was located at 100m from the experimental area, to collect external meteorological data. The covers in the greenhouse affected the microclimate, decreasing Qg, PAR, RH and ET and increasing T. The average transmission of solar radiation by the covers (white polyethylene, white polyethylene + thermal screen and white polyethylene + black screen) were, respectively, 23, 11 and 7%. The mean daily air temperatures within the greenhouse were about 6 o C higher in the white polyethylene and 3 o C higher in the environments covered by white polyethylene associated with the shading screens in comparison to the external temperatures. The types of covers, forming different microclimates, affected the growth and development of Gerbera plants. The growth was faster under the white polyethylene and slower under the white polyethylene associated with black screen. The plants cultivated under the greenhouse covered with white polyethylene and with white polyethylene associated with thermal screen filled the requirements in relation to the number of flower buttons. However, the same was not observed in the environment covered with white polyethylene associated with black screen. About the stem size, all the cultivated plants under all environmental conditions not presented the minimum required value (10 cm). In general, the microclimate influenced by the different covers offered adequated conditions for the cultivation of Gerbera, during autumn and winter periods. However, it is not possible to be sure that these conditions are representative for the whole year stations, being recommended forward studies comparing different cover materials on different periods of the year, searching for a better comprehension of the microclimate influence on the commercial production of Gerbera.

With the consolidation of Fortaleza as a major urban center in the ninth century and XX, and with the creation of its metropolitan region in the 1970s, is observed intensification in urban density and therefore a disclosure of city environmental problems, including those related to urban climate . In this perspective it was proposed to investigate, following the methodology of the Urban Climate System of Monteiro (1976, 2003), the climate in intra-urban areas of Fortaleza, specifically the green spaces and surroundings, aiming to analyze the thermal contrasts these areas with the gifted environments of construction. Samples were collected on representative days of contrasting seasonal periods, as follows: Autumn (on 25 and 26 April 2013), winter (27 and 28 August 2013), and the dry season with intense winds and Finally, in days (21 and 22 November 2013). Through the methodology proposed by Bargos, 2010, categorizing, spatial in Public Areas Green and potentially public. The description of each green area of the city were also held. Consideration was also the green area per inhabitant Index (IAV), as territorial scale opted for Regional later cauculando She administered the distribution of green areas in the city as a whole. As a result, Fortaleza has somo result of Green Areas Mapping the total of 13.34 m² / h (Public green areas) and 1.88 m² / h (Green Area Public Potentially). We observed the variation in temperature significantly intra-urban environment in general. The inner points thermal amplitudes were lower than the external points, the latter being more warm in the four sample areas analyzed.

Full textThe main purpose of this research is the effects of vegetation in urban microclimate conditions, under the premise that the presence of vegetation influences the microclimate and its surroundings. Considering different forms of green space distribution and using native species, it could quantify the intensity and spatial distribution for the microclimate effects by a vegetated area. The modifications of air temperature and the surface temperature at the level of the pedestrians were analyzed based on energy balance and computer models. Parametric simulations on ENVI-met were done to investigate the effect of green areas distribution (linear forms, large mass of vegetation and small groups of trees) and were compared with on-site measurement data. The simulation results showed the impact of urban vegetation for climatic aspects. The outputs indicated that the vegetation effect is local and do not have a significant influence beyond the limits of the green area. Regarding to the intensity of vegetation effect, the average difference between air temperature under the trees and above the streets is 1.5ºC. While the shadowing of a dense tree (LAI=10) showed an average difference of 23ºC for superficial temperatures between green spaces and the street. This result pointed out that green area is an important strategy to mitigate the heat island effect in city centers, as it can prevent asphalt and concrete from heating and releasing long wave radiation during night time.

Full textFrom the Brazilian biomes, the Cerrado has been the most widely and rapidly converted to agribusiness in recent years. The expansion of agricultural frontier over the Cerrado domain resulted in thousands of small fragments embedded in matrices of low similarity, causing a series of negative impacts on the natural ecosystem. Habitat fragmentation is considered one of the most serious threats to the conservation of biodiversity and ecological consequences vary, being intensified in the range of transition between matrix and fragment. The edge effects are caused by biotic and physical changes in marginal areas of the islands of natural vegetation, promoting changes in microclimatic characteristics, which leads to a series of important changes in the ecosystems. The aim of this study was to investigate the existence of edge effect and their consequences on the plant community of Cerrado sensu stricto. The study was conducted in Cerrado fragment with an area of 980.8 ha, located in the municipality of Iaras, SP, whose surrounding area was occupied by pasture for about a century. Structure and floristic composition of distinct vegetation layers was assessed at different distances from the edge (0, 10, 20, 40 and 80 m). Climatic data were collected in two seasons (dry and wet), at the same distances withing the fragment and also in the matrix (10 m away from the edge). The existence of a gradient of vegetation composition or structure and the microclimatic variables related to distance from the edge was investigated. No changes in microclimate and structure or composition of the wood layers related to distance from the edge was observed. Although independent of the microclimate and therefore different from classic edge effects, invasion by the African grass Urochloa decumbens (braquiária) was detected as the only consequence of exposure of the periphery of the cerrado sensu stricto to the pressures of the matrix, causing the exclusion of native grasses and inhibiting the development of small woody plants. The absence of edge effect on other components of the vegetation suggests, at first, that this is not a major threat to the conservation of the Cerrado. However, the biological invasion by the African grass is relatively recent (it was locally introduced about three decades ago) and its consequences have not been adequately assessed. It is possible that their impacts on the upper strata of the vegetation may be observed in future, when the inhibition of regeneration of shrub and tree species jeopardize the dynamics of plant community and the replacement of adults in the populations of these species. In addition, at present the invasion has significant impacts only over 0-20 m from the edge, but it is impossible to predict whether the invasive grass will expand or not into the core area of the fragment in the future.

Full textThe objective of this work is to quantify the impact of vegetation on urban microclimates, under the canopy, due to soil-vegetation-atmosphere interactions. It considers the following effects: 1) the canopy itself, expressed by the variable leaf area index - LAI and the geometric openness distribution in the canopy (gap fraction); 2) the soil coverage, expressed by soil composition, soil temperature and soil humidity, and 3) the local microclimatic variables (air temperature, humidity, solar radiation, mean radiant temperature, surface temperature, wind direction and wind speed). Considering the impact of vegetation on urban microclimates as a function of soil-vegetation-atmosphere, and based on the outcomes of preview studies, this work starts from the hypothesis that for São Paulo climate and as a result of evapotranspiration and shadowing process, the reduction of air temperature under the canopy will be between 1°C to 2°C and for surface temperature, it will be around 20°C, both in relation to an area without tree shadowing. These effects are restricted to the borders of the park, especially under the conditions of low wind speed, approximately 1m/s. The methods are: 1) inductive, based on field measurements in summer and winter at Tenente Siqueira Campos Park (Trianon Park), in the city of São Paulo, registering microclimatic data and collecting information for canopy and soil; and 2) deductive, with the calibration of measured and simulated data by ENVI-met 3.1 Beta 5 and the simulation for different scenarios varying the canopy characteristics. To estimate the average leaf density for trees canopy two no-destructive indirect methods were applied: measurement of LAI using the equipment LAI-2000 (LI-COR) and the analysis of hemispheric photographs, using a software application Can-Eye. According to the simulation results, for different characteristics for canopy, it could be verified a maximum reduction of 1ºC in air temperature and 19°C for surface temperature, when comparing the obtained value under a dense canopy (elliptical form and LAI of 5m2/m2) to the conditions on the street. The maximum extension of these effects were up to 5m from the limits of the park, considering 1m/s for wind speed and 40% for soil humidity in the upper layer (0-20cm). The thermal index TEP calculated and it could be seen that the reduction of 1°C for air temperature can represent from 3°C to 5°C in terms of thermal comfort of people. By these results, the initial hypothesis has proven to be correct and showed not only the importance of the type of vegetation selected (canopy form, LAI values and geometric distribution of canopy openness) but also the characteristics of the surrounding environment (microclimatic and soil conditions). Furthermore, it will contribute to formulate public politics aiming to mitigate urban warming effect, mainly during daytime, in tropical cities.

Simulation models play an important role in the design, analysis, and optimization of modern energy and environmental systems at building or urban scale. However, due to the extreme complexity of built environments and the sheer number of interacting parameters, it is difficult to obtain an accurate representation of real-world systems. Thus, model calibration and uncertainty analysis hold a particular interest, and it is necessary to evaluate to what degree simulation models are imperfect before implementing them during the decision-making process. In contrast to the extensive literature on the calibration of building performance models, little has been reported on how to automatically calibrate physics-based urban microclimate models. This thesis illustrates a general methodology for automatic model calibration and, for the first time, applies it to an urban microclimate system. The study builds upon the previously reported and updated Urban Weather Generator (UWG) to present a deep look into an existing urban district area in downtown Abu Dhabi (UAE) during 2017. Based on 30 candidate inputs covering the meteorological factors, urban characteristics, vegetation variables, and building systems, we performed global sensitivity analysis, Monte Carlo filtering, and optimization-aided calibration on the UWG model. In particular, an online hyper-heuristic evolutionary algorithm (EA) is proposed and developed to accelerate the calibration process. The UWG is a fairly robust simulator to approximate the urban thermal behavior for dierent seasons. The validation results show that, in single-objective optimization, the online hyper-heuristics can robustly help EA produce quality solutions with smaller uncertainties at much less computational cost. Finally, the resulting calibrated solutions are able to capture weekly-average and hourly diurnal profiles of the urban outdoor air temperature similar to the measurements for certain periods of the year.

Full textThree separate contemporary climate controlled greenhouse rooms in the Sears Plant Growth Facility located at the University of Missouri, Columbia, MO, USA were selected for microclimate analysis. Temperature, relative humidity, and incoming solar radiation data were logged hourly between 5/9/12 and 9/5/12 to test the efficacy of current management practices and to improve understanding of the spatial and temporal climate variability inside the greenhouse rooms. The average horizontal temperature gradient was 0.08 °C×m -1 and the maximum horizontal temperature gradient was 0.83 ºC×m -1. The average vertical temperature gradient was 2.27 °C×m -1 and the maximum lapse rate was 11.65 °C×m-1. Vapor pressure deficit (VPD) calculations were made using data as a proxy to assess plant physiological response to internal conditions. The average horizontal VPD gradient was 0.025 kPam-1 and the maximum VPD gradient was 0.350 kPa×m-1. Collectively, results indicate a heterogenous distribution of temperature and vapor pressure deficit created primarily by the active cooling system. Several recommendations are supplied to improve the homogeneity of the internal greenhouse climate, which will lead to increased productivity and profits for greenhouse managers.

Full textAt the reproductive stage, rice spikelets are sensitive to cold and to heat which can lead to spikelet sterility. However, it is not the air temperature but the temperature of the sensitive organ itself during some specific sensitive stages that is involved. There are three different strategies to cope with thermal stress: 1) physiological tolerance of a particular variety; 2) temporal escape of the stress thanks to phenology and time of day of anthesis (TOA) adjustments; 3) stress avoidance through microclimate generated by crop architecture and transpiration. This PhD aims to characterize the effect of environment on 2) and 3) and to attain this goal, the same experiment was conducted with four rice varieties irrigated and grown in four different climatic environments (Philippines, Senegal two seasons, France). Even though few varietal differences were observed within a site, a great variability of TOA and difference of temperature (TD) between panicle (Tp) and air (Tair) exists in response to the environment. Anthesis duration is stable and limited to 2 hours per day, whereas time of onset of anthesis varied between 3.4 to 6.75 hours after sunrise. During anthesis, observed TD varied between +2.5 and -9.5°C. TOA and TD are mostly explained with Tair and VPD (Vapour Pressure Deficit) observed before (TOA) or during (TD) anthesis. A significant correlation between spikelet sterility (due to cold or heat) and Tp at sensitive stages was established across sites and varieties. Those results showed that for irrigated rice, humid and moderately hot environments are more subject to heat stress sterility than very hot but dry environments, because panicle and canopy transpiration are favored by high VPD. Ultimately, RIDEV V.2 crop model (predicting spikelet sterility) was developed to integrate the previous results and Tp simulations were compared to another Tp model (IM2PACT) simulations, developed independently with a different approach in Japan. Those two models are robust and future collaborations will lead to complete model validations and maybe integration in a new modeling tool to answer the need in evaluating the impact of different climate change scenarios and the adaptation of crop response to those changes.In a short term, the results of this study will enable to 1) help breeders providing them new interest traits for thermal tolerance, and 2) define geographic zoning for high heat stress risk for irrigated rice, for present and future climate change scenarios. Complementary studies are needed to apply this approach to non irrigated system

Full textAgroforestry, and more specifically sylvo-arable systems, are poorly studied systems with agronomic and environmental interests in temperate systems. They could provide a favorable microclimate for vegetable crops grown in organic agriculture in Mediterranean pedoclimatic context. However, there are still few scientific references on the subject, and the outcome of the interactions between trees and cultures are still unknown. The microclimate generated by old trees is likely to alter the relations between crops, pests and generalist predators, which can condition the performance of an agroforestry system.This thesis had two main objectives:• To evaluate the impact of canopy openness on ground beetle diversity and activity-density• Identify how the microclimate can influence natural regulation processes.Agroforestry systems develop over long periods (pluriannual): the study focused on a system already having 20-year-old trees to study the impact on microclimate and soil fauna. To modulate this microclimate, a canopy opening gradient has been realized. The ambient air temperature, the hygrometry and the percentage of canopy aperture were then measured.First, the soil fauna was sampled for 2 years and the structure of the Carabidae communities was analyzed from a taxonomic and functional point of view, using 5 ecological traits. The results show that the taxonomic structure is poorly affected, but that both species specific activity-density and functional traits are modified by the canopy openness, which favored species with affinity for closed and moist environments.The diel activity of two abundant predators was characterized in a hot summer period (July), and cooler (September). The results show that both the season and the opening of the canopy can modify the daily rhythms of the most abundant Arachnidae and Carabidae (Pardosa hortensis, Pseudoophonus rufipes).Thirdly, the work focused on the predation potential of predators of soil fauna, using sentinel preys method at two periods, (June and August). The results show that for at least one period, the predation potential on Lepidoptera larvae (Cydia pomonella) was different between treatments. These differences are probably correlated with differences in activity-density and microclimatic differences induced by the differences in canopy treatmentLastly, the study focused on lettuce crops and the damage caused by slugs in the different treatments, on the visible leaves. More damage under the trees was observed, despite a similar activity- density of Arion lusitanicus and Deroceras reticulatum compared to control in June, where the damage increased significantly. The methods used (boards, neutral traps and attractive traps) presented different efficiencies, whose respective interest is discussed

he different environmental conditions promoted by geomorphological changes, make the recovery of forest ecosystems of the Atlantic Forest challenging. In the southern state of Rio de Janeiro, where there are the semideciduous seasonal forests, degradation promoted during the coffee cycle and the current urban sprawl, restricted the seasonal forests to small fragments, responsible for ground cover, water harvesting, shelter for native fauna and representation of regional floristic diversity. Such fragments occur on geomorphological landforms variations called concave and convex, able to determine the behavior of surface water and influence the ecological dynamics of plant communities occurring. Studies to date do not allow to determine specific environmental standards between landforms, as only relate the soil variations catenary gradient and its influence on the distribution of species. Thus, it is necessary to formulate a replicable design, able to identify edaphic and microclimatic standards specific to the concave and convex landforms, and determine its influence on the distribution of species. To this end, we selected three concave landforms and three convex to perform the study, and installed 54 plots of 100m2 each landform. In each plot were collected for the phytosociological study, the diameter and height of tree species with DAP?5cm. The phytosociological parameters were calculated diversity indices, floristic similarity the sample sufficiency and compared the structural means by 5% Levene test. In each plot, soil samples were collected at depths of 0-5, 5-10 and 10-20 cm, totaling 108 samples composed of five single samples, used for grain size analysis and chemical soil fertility. The pattern of distribution of species was correlated with soil and microclimate variables of each landform simultaneously with the aid of multivariate analysis reductional (Multivariate Factor Analysis, PCA), ordenativas (Canonical Correlation Analysis and Canonical Correspondence) and agglomerative (Hierarchical Cluster). The results indicate subtle differences between soil conditions and a specific microclimate between landforms, capable of influencing the distribution of specific groups of species, however, without characterizing the formation of different plant communities. Considering the specific environmental conditions of each landform, the main variables that coordinate and species related to these conditions, it was possible to offer technical support for recupara??o of degraded and disturbed areas, as well as the enrichment of Forest ecosystems fragments of Atlantic Forest
As diferentes condi??es ambientais promovidas por varia??es geomorfol?gicas, tornam a recupera??o de ecossistemas florestais da Floresta Atl?ntica um grande desafio. Na regi?o Sul do Estado do Rio de Janeiro, onde ocorrem as Florestas Estacionais Semideciduais, a degrada??o promovida durante o ciclo do caf? e o atual crescimento urbano desordenado, restringiram as Florestas Estacionais a pequenos fragmentos, respons?veis pela cobertura do solo, capta??o de ?gua, abrigo para fauna nativa e representa??o da diversidade flor?stica regional. Tais fragmentos ocorrem sobre varia??es geomorfol?gicas denominadas pedoformas c?ncavas e convexas, capazes de determinar o comportamento das ?guas superficiais e influenciar a din?mica ecol?gica das comunidades vegetais ocorrentes. Estudos realizados at? o momento n?o permitem determinar padr?es ambientais espec?ficos entre pedoformas, pois relacionam apenas as varia??es ed?ficas ao gradiente caten?rio e sua influ?ncia sobre a distribui??o das esp?cies. Desta forma, faz-se necess?ria a formula??o de um delineamento replic?vel, capaz de identificar padr?es ed?ficos e microclim?ticos espec?ficos para as pedoformas c?ncavas e convexas, al?m de determinar sua influ?ncia sobre a distribui??o das esp?cies. Para tal, foram selecionadas tr?s pedoformas c?ncavas e tr?s convexas para realiza??o do estudo, sendo instaladas 54 parcelas de 100m2 em cada pedoforma. Em cada parcela foram coletados, para o estudo fitossociol?gico, o di?metro e altura das esp?cies arb?reas com DAP?5cm. Foram calculados os par?metros fitossociol?gicos, ?ndices de diversidade, similaridade flor?stica, a sufici?ncia amostral e comparadas as m?dias estruturais pelo teste de Levene a 5%. Em cada parcela foram coletadas amostras de solo nas profundidades de 0-5, 5-10 e 10-20 cm, totalizando 108 amostras compostas por cinco amostras simples, utilizadas para as an?lises granulom?tricas e da fertilidade qu?mica do solo. O padr?o de distribui??o das esp?cies foi correlacionado com as vari?veis ed?ficas e microclim?ticas de cada pedoforma simultaneamente, com auxilio de an?lises multivariadas reducionais (An?lise Fatorial Multivariada, PCA), ordenativas (An?lise de Correla??o Can?nica e Correspond?ncia Can?nica) e aglomerativas (Cluster Hier?rquico). Os resultados indicam diferen?as sutis entre as condi??es ed?ficas e um microclima espec?fico entre pedoformas, capaz de influenciar a distribui??o de grupos espec?ficos de esp?cies, por?m, sem caracterizar a forma??o de comunidades vegetais distintas. Considerando a condi??o ambiental espec?fica de cada pedoforma, as principais vari?veis que as coordenam e as esp?cies relacionadas a tais condi??es, foi poss?vel oferece subs?dios t?cnicos para recupara??o de ?reas degradas e perturbadas, bem como o enriquecimento de fragmentos de ecossistemas Florestais da Floresta Atl?ntica

Full textBiologically, the mangrove ecosystems are among the most productive and important in the world, providing resources and services exclusive to societies and coastal systems. Its functions include the stabilization of the shoreline and reduction the impact of extreme weather events such as in cases of storms and hurricane. However, this ecosystem have been presenting significant changes arising from anthropogenic influence on the environment, modifying the vegetation and that, in turn, influence the entire ecosystem, including the microclimatic interactions. The research aims to assess the relation between controls (vegetation structure, tide variations and atmospheric systems) and climatic attributes (air temperature, absolute humidity, solar radiation, wind and rainfall) in the mangrove on the bar the Ribeira-Iguape/SP. To this end, was installed one microclimatic tower containing two weather stations to obtain an analysis of climatic attribute variations above and below the canopy of mangrove. Moreover, was analyzed the structural features of the mangrove vegetation. It was found an increase in transmissivity of solar radiation in the mangrove canopy, a reduction in albedo and a decrease in vegetable interception. These changes are associated with the degradation of the forest, who do not have new individuals who thrive in the environment, there is no renewal of the ecosystem as a result of the presence of macrophytes in the study area. It was proven the important role of tidal in mangrove areas, contributing with input and output power, favoring the cooling / heating relative on the environment. It was concluded that, from the microclimatic point of view, there are significant differences above and below the mangrove canopy. In the case of the maximum temperature, the differences were greater than 5 ° C and exceed 10 ° C between the air and soil temperature. It is noticeable in this scalar level, the coupling between the upper climatic scales with the microclimate level. Was observed how the climatic attributes are connected and how the differences between the climatic attributes are evident in inferior temporal scales.

Based on the fact that the sugar-alcohol sector is a growing activity, driven by investments in production technology, the State of Pernambuco has excelled in this scenario, as the use of technique of in vitro propagation. Accordingly, this work sought to analyze the microclimate and evaluate the growth and development of sugarcane seedlings in acclimatization under two types of roofs in protected environment. The survey was conducted by the experimental area of Usina São José, in the municipality of Igarassú-PE, latitude of 7° 48' 37.32 "S, longitude 34° 59' 49.23"O and height of 34 m. The protected environment was covered with milky plastic and divided into two environments, an associated shading mesh termorreflective (TA) and the other associated with black shading mesh (TB). The variables studied were: meteorological variables (solar radiation, air temperature, relative humidity) and crop variables (stem length, diameter of the stem, leaf length, number of leaves, plant height and leaf area). 12 trays with 108 tubes each, were employed both for TA and TB, being randomly chosen for the biometric monitoring 4 tubes. The experimental design used was entirely casualized (DIC) and Tukey test (p<0.05) for comparing the averages. The production environment under TA provided the best biometric results of development of seedlings from sugarcane, as a result of the greater availability of solar radiation in the production environment.
Baseado no fato de que o setor sucroalcooleiro é uma atividade em pleno crescimento, impulsionado por investimentos em tecnologia de produção, o Estado de Pernambuco tem-se destacado nesse cenário, como a utilização de técnica de propagação in vitro. Nesse sentido, objetivou-se com este trabalho analisar o microclima e avaliar o crescimento e desenvolvimento de mudas de cana-de-açúcar em aclimatização sob dois tipos de coberturas em ambiente protegido. A pesquisa foi conduzida junto à área experimental da Usina São José, situada no município de Igarassú - PE, latitude de 7°48’37,32” S, longitude de 34°59’49,23” O e altitude de 34 m. O ambiente protegido foi coberto com plástico leitoso e dividido em dois ambientes, um associado a malha de sombreamento termorrefletora (TA) e outro associado a malha de sombreamento preta (TB). As variáveis estudadas foram: variáveis meteorológicas (radiação solar, temperatura do ar, umidade relativa do ar) e variáveis de cultura (comprimento do colmo, diâmetro do colmo, comprimento da folha, número de folhas, altura da planta e área foliar). Utilizou-se 12 bandejas com 108 tubetes cada, tanto para TA quanto para TB, sendo escolhidos aleatoriamente 4 tubetes para o acompanhamento biométrico. O delineamento experimental utilizado foi Inteiramente casualizado (DIC) e o teste de Tukey (p<0,05) para comparação entre as médias. O ambiente de produção sob TA proporcionou os melhores resultados biométricos de desenvolvimento das mudas de cana-de-açúcar, em decorrência da maior disponibilidade de radiação solar neste ambiente de produção.

The application of using Unmanned Aerial Vehicles (UAVs) to locate thermal updraft currentsis a relatively new topic. It was first proposed in 1998 by John Wharington, and, subsequently, several researchers have developed algorithms to search and exploit thermals. However, few people have physically implemented a system and performed field testing. The aim of this project was to develop a low cost system to be carried on a glider to detect thermals effectively. A system was developed from the ground up and consisted of custom hardware and software that was developed specifically for aircraft. Data fusion was performed to estimate the attitude of the aircraft; this was done using a direction cosine (DCM) based method. Altitude and airspeed data were fused by estimating potential and kinetic energy respectively; thus determining the aircraft’s total energy. This data was then interpreted to locate thermal activity. The system comprised an Inertial Measurement Unit (IMU), airspeed sensor, barometric altitude sensor, Global Positioning System (GPS), temperature sensor, SD card and a realtime telemetry link. These features allowed the system to determine aircraft position, height, airspeed and air temperature in realtime. A custom-designed radio controlled (RC) glider was constructed from composite materials in addition to a second 3.6 m production glider that was used during flight testing. Sensor calibration was done using a wind tunnel with custom designed apparatus that allowed a complete wing with its pitot tube to be tested in one operation. Flight testing was conducted in the field at several different locations over the course of six months. A total of 25 recorded flights were made during this period. Both thermal soaring and ridge soaring were performed to test the system under varying weather conditions. A telemetry link was developed to transfer data in realtime from the aircraft to a custom ground station. The recorded results were post-processed using Matlab and showed that the system was able to detect thermal updrafts. The sensors used in the system were shown to provide acceptable performance once some calibration had been performed. Sensor noise proved to be problematic, and time was spent alleviating its effects.

Full textAgrivoltaic systems, combining solar panels and crops on the same land were proposed in the early 1980’s as a solution to solve land use conflict. Introduced in 2010 in Montpellier, the concept has proven itself associating fixed panels to multiple food crops. Total land productivity was improved, thanks to plant acclimation to shade. In this thesis, fixed panels were replaced with mobile panels, adjustable along the day. The aim of this work was to optimize solar panel orientations to maximise total land productivity without threatening the crop culture. Growth and development of lettuces were analysed in controlled conditions and in the field under several shading conditions by fixed or mobile panels. Total land productivity was improved with mobile panels in comparison with fixed panels, maintaining lettuce yield under certain conditions. Through an ecophysiological approach based on plant development and its ability to intercept and convert light into biomass, the different shading conditions were shown to have a small impact in the plant leaf area dynamic despite large differences in accumulated dry mass associated with transmitted radiation at the plant level. This was due to differences in leaf development resulted in higher use of the transmitted radiation when it was reduced. This study proposed a modelling approach of the incidence of panel orientations on lettuce dry mass at harvest. The model allows an optimisation of solar panels controlling as a function of climate scenario and crop and electricity production objectives

Studies of thermal comfort in climatic chambers have the limitation of disregarding the user's adaptation to the environmental conditions. In order to overcome limitations of currentelly thermal comfort models, new investigations has been conducted to identify the thermal comfort in open spaces or free running buildings. Inserted in this context, this study has as general objective to evaluate the thermal sensation of the visitors of an urban park (Bica) in João Pessoa-PB, a city of hot and humid weather climate in Northeastern Brazil. As methodology, we used microclimatic monitoring of the variables: air temperature, globe temperature, humidity, wind speed and solar radiation. Questionnaires were also applied to visitors to assess the feeling of thermal comfort within the park. The microclimatic data were collected with the aid of a portable meteorological station DAVIS and a thermal stress meter - TGD300. To carry out the statistical analyzes was used the STATISTIC 7.0 program. Through statistical analysis it was possible to identify a comfort range between 23-31°C. The logistic regression model showed that three climate variables (air temperature, wind speed and mean radiant temperature) have significant effect on the thermal sensation vote felt by respondents. When the thermal sensation vote was compared to the PMV/PPD index, it was verified in loco was always in a lower category to the PMV. The results found in this research can help in planning the city in the search for a more banlanced urban environmrt, rspecially with regard to thermal confort.
Estudos de conforto térmico em câmara climatizada apresentam a limitação de desconsiderar a adaptação do indivíduo às condições ambientais. Com objetivo de superar limitações dos modelos atuais de conforto térmico, pesquisas têm sido realizadas para identificar os limites de conforto em ambientes sem climatização e em condições naturais, dentre elas, destacam-se os estudos de conforto em espaços abertos. Inserido nesse contexto este estudo tem como objetivo geral avaliar a sensação térmica dos visitantes de um parque urbano (Bica) em João Pessoa-PB, uma cidade de clima quente e úmido no nordeste do Brasil. Como metodologia utilizou-se de monitoramento microclimático das variáveis: temperatura do ar, temperatura do globo, umidade, velocidade do vento e radiação solar. Também foram aplicados questionários aos visitantes a fim de avaliar a sensação de conforto térmico dentro do parque. Os dados microclimáticos foram coletados com auxilio de uma mine estação meteorológica portátil DAVIS e um medidor de stress térmico- TGD300. Para realizar as análises estatísticas foi utilizado o programa STATISTIC 7.0. Através da análise estatística foi possível identificar um intervalo de conforto de 23° a 31°C, o modelo de regressão logística mostrou que três variáveis climáticas (temperatura do ar, velocidade do vento, temperatura radiante média) têm influência sobre o voto de sensação térmica dos entrevistados. Quando o voto de sensação térmica foi comparado com o índice de conforto PMV/PPD observaram-se diferenças significativas entre as duas variáveis, a sensação térmica verificada in loco esteve sempre em uma categoria inferior ao PMV. Os resultados encontrados nesta pesquisa podem auxiliar ao planejamento da cidade na busca por um ambiente urbano mais equilibrado especialmente no que se refere ao conforto térmico.
