For total ozone, the O3-CCI approach consists of minimizing sources of bias and systematic uncertainties by applying a common retrieval algorithm to all level 1 data sets, in order to enhance the consistency between the level 2 data sets from individual sensors. Measurements from the three sensors span more than 16 years, from to In particular, we investigate possible dependencies in these new GODFIT v3 total ozone data sets with respect to latitude, season, solar zenith angle, and different cloud parameters, using the most adequate type of ground-based instrument.
We show that these three O3-CCI total ozone data products behave very similarly and are less sensitive to instrumental degradation, mainly as a result of the new reflectance soft-calibration scheme. The mean bias to the ground-based observations is found to be within the 1 plus or minus 1 percent level for all three sensors while the near-zero decadal stability of the total ozone columns TOCs provided by the three European instruments falls well within the percent requirement of the European Space.
Observing lowermost tropospheric ozone pollution with a new multispectral synergic approach of IASI infrared and GOME -2 ultraviolet satellite measurements. Tropospheric ozone is currently one of the air pollutants posing greatest threats to human health and ecosystems. Monitoring ozone pollution at the regional, continental and global scale is a crucial societal issue. Only spaceborne remote sensing is capable of observing tropospheric ozone at such scales.
The spatio-temporal coverage of new satellite-based instruments, such as IASI or GOME -2, offer a great potential for monitoring air quality by synergism with regional chemistry-transport models, for both inter-validation and full data assimilation. However, current spaceborne observations using single-band either UV or IR measurements show limited sensitivity to ozone in the atmospheric boundary layer, which is the major concern for air quality.
This unique multispectral approach has allowed the observation of ozone plumes in the lowermost troposphere LMT, below 3 km of altitude over Europe, for the first time from space. Our first analyses are focused on typical ozone pollution events during the summer of over Europe. During these events, LMT ozone plumes at different regions are produced photo-chemically in the boundary layer, transported upwards to the free troposphere and also downwards from the stratosphere. Chlorophyll induced fluorescence retrieved from GOME 2 for improving gross primary productivity estimates of vegetation.
Mapping terrestrial chlorophyll fluorescence is a crucial activity to obtain information on the functional status of vegetation and to improve estimates of light-use efficiency LUE and global primary productivity GPP. GPP quantifies carbon fixation by plant ecosystems and is therefore an important parameter for budgeting terrestrial carbon cycles. Satellite remote sensing offers an excellent tool for investigating GPP in a spatially explicit fashion across different scales of observation.
The GPP estimates, however, still remain largely uncertain due to biotic and abiotic factors that influence plant production. Sun-induced fluorescence has the ability to enhance our knowledge on how environmentally induced changes affect the LUE. This can be linked to optical derived remote sensing parameters thereby reducing the uncertainty in GPP estimates.
Satellite measurements provide a relatively new perspective on global sun-induced fluorescence, enabling us to quantify spatial distributions and changes over time. Techniques have recently been developed to retrieve fluorescence emissions from hyperspectral satellite measurements. The spectral signatures of three basic components atmospheric: An empirically based principal component analysis PCA approach is applied similar to that of Joiner et al.
Here we show our first global maps of the GOME 2 retrievals of chlorophyll fluorescence. In view of optimizing the fluorescence retrieval, we will show the effect of the references. H2O is also involved in many important reaction cycles of atmospheric chemistry, e. Thus, long time series of global H2O data are highly required.
In contrast to existing H2O retrieval algorithms it does not depend on additional information like e. It includes an internal cloud-, aerosol-, and albedo correction which is based on simultaneous observations of the oxygen dimer O4. For measurements over partly cloud covered ground pixels, however, the true atmospheric H2O VCD might be in general systematically underestimated. The correlation of the GOME observations and the model data yield the following results: Theys, N. Measurements from the GOME -2 satellite instrument have been analyzed for tropospheric BrO using a residual technique that combines measured BrO columns and estimates of the stratospheric BrO content from a climatological approach driven by O3 and NO2 observations.
We show that the adopted technique enables to separate the stratospheric and tropospheric fractions of the measured total BrO columns and allows studying the BrO plumes in polar region in more detail. While several satellite BrO plumes can largely be explained by an influence of stratospheric descending air, we show that numerous tropospheric BrO hotspots are associated to regions with low tropopause heights as well.
Elaborating on simulations using the p-TOMCAT tropospheric chemical transport model, this finding is found to be consistent with the mechanism of bromine release through sea salt aerosols production during blowing snow events. We show that the adopted technique enables separation of stratospheric and tropospheric fractions of the measured total BrO columns and allows quantitative study of the BrO plumes in polar regions.
While some satellite observed plumes of enhanced BrO can be explained by stratospheric descending air, we show that most BrO hotspots are of tropospheric origin, although they are often associated to regions with low tropopause heights as well. Elaborating on simulations using the p-TOMCAT tropospheric chemical transport model, this result is found to be consistent with the mechanism of bromine release through sea salt aerosols production during blowing snow events. No definitive conclusion can be drawn however on the importance of blowing snow sources in comparison to other bromine release mechanisms.

The temporal and spatial variations of SO 2 columns over China were analyzed for the time period — Beijing and Chongqing showed a high concentration in the SO 2 columns, attributable to the use of coal for power generation in China and the characteristic of terrain and meteorology. The reduction of SO 2 columns over Beijing and surrounding provinces in was observed by OMI, which confirms the effectiveness of strict controls on pollutant emissions and motor vehicle traffic before and during Olympic and Paralympic Games. Noije, van T. We present a systematic comparison of tropospheric NO2 from 17 global atmospheric chemistry models with three state-of-the-art retrievals from the Global Ozone Monitoring Experiment GOME for the year Validation against Brewer measurements at the Iberian Peninsula.
In this analysis, spatially colocated, daily averaged ground-based observations performed by five well-calibrated Brewer spectrophotometers at the Iberian Peninsula are used. The period of study runs from January to December The agreement between satellite and ground-based TOC data is excellent R2 higher than 0. Nevertheless, the TOC data derived from both satellite instruments underestimate the ground-based data. On average, this underestimation is 1. The satellite-Brewer TOC differences for the two satellite instruments show a clear and similar dependence on the viewing zenith angle under cloudy conditions.
In this paper we present the first contiguous high-resolution spectra of the Earth's polarisation observed by a satellite instrument. The spectral resolution of these PMD RAW polarisation measurements varies from 3 nm in the ultraviolet UV to 35 nm in the near-infrared wavelength range. We first compare measurements of the polarisation from cloud-free scenes with radiative transfer calculations for a number of cases. We find good agreement but also a spectral discrepancy at nm, which we attribute to remaining imperfections in the calibration key data.
The GOME -2 polarisation spectra indeed show this behaviour and confirm the existence of the small discrepancy found earlier. Thirdly, we study the Earth polarisation for a variety of scenes.

Starting from the global monitoring of atmospheric nitrogen dioxide is carried out by the measurements of nadir-viewing GOME spectrometer aboard ERS-2 satellite. Continuous validation of that data by means of comparisons with well-controlled ground-based measurements is important to ensure the quality of GOME data products and improve related retrieval algorithms.
At the station of Issyk-Kul Kyrgyzstan the ground-based spectroscopic observations of NO2 vertical column have been started since The station is located on the northern shore of Issyk-Kul lake, meters above the sea level The site is equipped with grating spectrometer for the twilight measurements of zenith-scattered solar radiation in the visible range, and applies the DOAS technique to retrieve NO2 vertical column. It is included in the list of NDSC stations as a complementary one.

In particular cases, NO2 vertical profiles retrieved from the twilight ground-based measurements at Issuk-Kul were also included into comparison. This work was supported by International Association.

Characterization of nutrient deficiency in Hancornia speciosa Gomes seedlings by omitting micronutrients from the nutrient solution. The production of seedlings of this species is limited by a lack of technical and nutritional expertise. To address this deficiency, this study aimed to characterize the visual symptoms of micronutrient deficiency and to assess growth and leaf nutrient accumulation in H.
The treatments consisted of a group receiving complete nutrient solution and groups treated with a nutrient solution lacking one of the following micronutrients: The visual symptoms of nutrient deficiency were generally easy to characterize. Dry matter production was affected by the omission of micronutrients, and the treatment lacking Fe most limited the stem length, stem diameter, root length, and number of leaves in H.

Satellite measurements are sometimes the only information available on SO2 concentrations from volcanic eruption events. The detection of SO2 can furthermore serve as a proxy for the presence of volcanic ash that poses a possible hazard to air traffic. In that respect, knowledge of both the total vertical column amount and the effective altitude of the volcanic SO2 plume is valuable information to air traffic control. We present results from our algorithm for the simultaneous retrieval of total vertical columns of O3 and SO2 and effective SO2 plume height from GOME -2 backscattered radiance measurements.
The algorithm uses parameterized vertical SO2 profiles which allow for the derivation of the peak height of the SO2 plume, along with the trace gas total column amounts. To illustrate the applicability of the method, we present three case studies on recent volcanic eruptions: We find that the effective plume height can be obtained with a precision as fine as 1 km for moderate and strong volcanic events. Since this is valuable information for air traffic, we aim at incorporating the plume height information in the SACS system.
Lightning provides a natural source of nitrogen oxides, dominating the production in the tropical upper troposphere, with strong impact on tropospheric ozone and the atmosphere's oxidizing capacity. Recent estimates of lightning produced NOx LNOx are of the order of 5 Tg 3330 per year with still high uncertainties in the range of one order of magnitude. Simultaneously, cloud-to-ground CG flashes are counted by the U.
The enhancements can not be explained by transport of anthropogenic NOx and must be due to fresh production of LNOx. If simply extrapolated, this corresponds to a global LNOx production of 1. Both oxygenated Volatile Organic Compounds, OVOC, are key intermediate species produced during the oxidation of precursor hydrocarbons. Their short lifetime of a few hours in the lower troposphere links them to emission sources and makes them useful tracers of photochemical activity.
The highest column amounts of these OVOCs are recorded over regions with enhance biogenic emissions e. Enhanced OVOC values are also present over areas of anthropogenic activity and biomass burning e. America, Europe and Australia. The ratio of CHO. R GF s below 0. This decreasing tendency of R GF with increasing NO 2 is also observed when analyzing data for individual large cities, indicating that it is a common feature.
This is explained by the excellent correlation of the global retrieved column amounts of CHO. Full Text Available This work aimed to study the behavior of the species Schizolobium parahyba var.

We present the first directly retrieved global distribution of tropospheric column ozone from Global Ozone Monitoring Experiment GOME ultraviolet measurements during December to November The retrievals clearly show signals due to convection, biomass burning, stratospheric influence, pollution, and transport.
They are capable of capturing the spatiotemporal evolution of tropospheric column ozone in response to regional or short time-scale events such as the El Nino event and a DU change within a few days. The global distribution of tropospheric column ozone displays the well-known wave-1 pattern in the tropics, nearly zonal bands of enhanced tropospheric column ozone of DU at 20degSdegS during the austral spring and at 25degNdegN during the boreal spring and summer, low tropospheric column ozone of 33 DU at some northern high-latitudes during the spring.
Simulation from a chemical transport model corroborates most of the above structures, with small biases of GOME with monthly-averaged Measurement of Ozone and Water Vapor by Airbus in-service Aircraft MOZAIC tropospheric column ozone for these regions usually shows good consistency within 1 a standard deviations and retrieval uncertainties. Some biases can be accounted for by inadequate sensitivity to lower tropospheric ozone, the different spatiotemporal sampling and the spatiotemporal variations in tropospheric column ozone.
Observing atmospheric formaldehyde HCHO from space: Full Text Available Formaldehyde HCHO column data from satellites are widely used as a proxy for emissions of volatile organic compounds VOCs, but validation of the data has been extremely limited. All retrievals feature a HCHO maximum over Arkansas and Louisiana, consistent with the aircraft observations and reflecting high emissions of biogenic isoprene. Our results support the use of satellite HCHO data as a quantitative proxy for isoprene emission after correction of the low mean bias. There is no evident pattern in the bias, suggesting that a uniform correction factor may be applied to the data until better understanding is achieved.
It is shown that such reports can be interpreted as a criticism of the social relations of the slave era by issuing some warnings to the landowners who failed to look after the health of their slaves. Global satellite measurements of solar-induced fluorescence SIF from chlorophyll over land and ocean have proven useful for a number of different applications related to physiology, phenology, and productivity of plants and phytoplankton.
Terrestrial chlorophyll fluorescence is emitted throughout the red and far-red spectrum, producing two broad peaks near and nm. From ocean surfaces, phytoplankton fluorescence emissions are entirely from the red region nm peak. Studies using satellite-derived SIF over land have focused almost exclusively on measurements in the far red wavelengths greater than nm , since those are the most easily obtained with existing instrumentation.
Here, we examine new ways to use existing hyperspectral satellite data sets to retrieve red SIF wavelengths less than nm over both land and ocean. Red SIF is thought to provide complementary information to that from the far red for terrestrial vegetation. The satellite instruments that we use were designed to make atmospheric trace-gas measurements and are therefore not optimal for observing SIF; they have coarse spatial resolution and only moderate spectral resolution 0. Terrestrial SIF has been estimated with ground-, aircraft-, or satellite-based instruments by measuring the filling-in of atmospheric andor solar absorption spectral features by SIF.
Our approach makes use of the oxygen O2 gamma band that is not affected by SIF. In the tropical Pacific a significant seasonal variation is detected. Tropospheric excess ozone is enhanced during the biomass burning season from September to November due to outflow from the continents. Samoa Backtrajectory calculations show that none of the airmasses arriving over the three locations experienced anthropogenic pollution e. Consequently other sources of ozone have to be considered. One possible process leading to an increase of tropospheric ozone is stratosphere-troposphere-exchange.
An analysis of the potential vorticity along trajectories arriving above each of the locations reveals that airmasses at Tahiti are subject to enhanced stratospheric influence, compared to Am. Samoa and Fiji. As a result this study shows clear incidents of transport of airmasses from the stratosphere into the troposphere.

For model output evaluation we primarily employ WV total column data from the Global Ozone Monitoring Experiment GOME on ERS-2, which is the only instrument capable measuring WV on a global scale and over all surface types with a substantial data record from to the present. We conclude that deficiencies in model parameters shared by MATCH and NRA, like in the surface evaporation rates and regional transport patterns, are likely to lead to the observed differences.

Monthly average regional differences between MATCH modelled WV columns and the observations can be as large as 2 cm, based on the analysis of three years. Differences in the global mean WV values are, however, below 0. We find that MATCH has problems in modelling the WV content in regions of strong upward convection like, for example, along the Inter Tropical Convergence Zone, where it appears to be generally too dry as compared to the observations.
Volcanic SO2 fluxes derived from satellite data: Full Text Available Sulphur dioxide SO2 fluxes of active degassing volcanoes are routinely measured with ground-based equipment to characterize and monitor volcanic activity. SO2 of unmonitored volcanoes or from explosive volcanic eruptions, can be measured with satellites. However, remote-sensing methods based on absorption spectroscopy generally provide integrated amounts of already dispersed plumes of SO2 and satellite derived flux estimates are rarely reported.
Here we review a number of different techniques to derive volcanic SO2 fluxes using satellite measurements of plumes of SO2 and investigate the temporal evolution of the total emissions of SO2 for three very different volcanic events in We show that satellite data can provide fluxes with a sampling of a day or less few hours in the best case. Generally the flux results from the different methods are consistent, and we discuss the advantages and weaknesses of each technique. Although the primary objective of this study is the calculation of SO2 fluxes, it also enables us to assess the consistency of the SO2 products from the different sensors used.

Full Text Available Hancornia speciosa Gomes Apocynaceae is a fruit tree, popularly known as mangabeira, and it is widely distributed throughout Brazil.
Several parts of the plant are used in folk medicine, and the leaf and bark extracts have anti-inflammatory, antihypertensive, antidiabetic, and antimicrobial properties. In this study, we investigated the chemical composition of the ethanolic extract of Hancornia speciosa leaves EEHS and its antioxidant, antimicrobial, and cytotoxic activities as well as the mechanisms involved in cell death. The antioxidant activity of the EEHS was investigated using the method that involves the scavenging of 2,2-diphenylpicrylhydrazyl free radicals as well as the inhibition of oxidative hemolysis and lipid peroxidation induced by 2,2'-azobis 2-amidinopropane in human erythrocytes.
The antimicrobial activity was determined by calculating the minimum inhibitory concentration, minimum bactericidal concentration, minimum fungicidal concentration, and zone of inhibition. Kasumi-1 leukemic cells were used to assess the cytotoxic activity and mechanisms involved in cell death promoted by the EEHS. The chemical compounds identified were quinic acid, chlorogenic acid, catechin, rutin, isoquercitrin, kaempferol-rutinoside, and catechin-pentoside.
The EEHS demonstrated antioxidant activity via the sequestration of free radicals, inhibition of hemolysis, and inhibition of lipid peroxidation in human erythrocytes incubated with an oxidizing agent. The antimicrobial activity was observed against American Type Culture Collection ATCC and hospital strains of bacteria and fungi, filamentous fungi and dermatophytes.
The cytotoxic activity of the EEHS was induced by apoptosis, reduction of the mitochondrial membrane potential, and activation of cathepsins. Together, these results indicate the presence of phenolic compounds and flavonoids. Joiner, J. Globally mapped terrestrial chlorophyll fluorescence retrievals are of high interest because they can provide information on the functional status of vegetation including light-use efficiency and global primary productivity that can be used for global carbon cycle modeling and agricultural applications.
Previous satellite retrievals of fluorescence have relied solely upon the filling-in of solar Fraunhofer lines that are not significantly affected by atmospheric absorption. Although these measurements provide near-global coverage on a monthly basis, they suffer from relatively low precision and sparse spatial sampling.
Here, we describe a new methodology to retrieve global far-red fluorescence information; we use hyperspectral data with a simplified radiative transfer model to disentangle the spectral signatures of three basic components: An empirically based principal component analysis approach is employed, primarily using cloudy data over ocean, to model and solve for the atmospheric absorption. Through detailed simulations, we demonstrate the feasibility of the approach and show that moderate-spectral-resolution measurements with a relatively high signal-to-noise ratio can be used to retrieve far-red fluorescence information with good precision and accuracy.
Near-global coverage is provided within a few days. We are able to show clearly for the first time physically plausible variations in fluorescence over the course of a single month at a spatial resolution of 0. Global monitoring of terrestrial chlorophyll fluorescence from moderate-spectral-resolution near-infrared satellite measurements: Full Text Available Globally mapped terrestrial chlorophyll fluorescence retrievals are of high interest because they can provide information on the functional status of vegetation including light-use efficiency and global primary productivity that can be used for global carbon cycle modeling and agricultural applications.
During the dry monsoon season between January and March , local measurements were carried out from ground based platforms and were compared with satellite based data. The objective of this study was to characterise stratospheric and tropospheric trace gas amounts in the equatorial region, and to investigate the impact of air pollution at this remote site.
The measurements were conducted using two different observation modes off-axis and zenith-sky. This technique allows the separation of the tropospheric and stratospheric columns for different trace gases like O3 and NO2. In addition, the analysis of the O3-sonde measurements allowed the determination of the tropospheric O3 amount. The comparison shows that the results of all three measurement systems agree within their error limits. During the INDOEX campaign, mainly background conditions were observed, but in a single case an increase of tropospheric NO2 during a short pollution event was observed from the ground and the impact on the vertical columns was calculated.
GOME measurements showed evidence for small tropospheric contributions to the BrO budget, probably located in the free troposphere and.

The objective of this research was the evaluation of the genetic diversity and genetic structure of H. The genetic variability was assessed using 11 allozyme loci with a sample of individuals distributed in six natural populations located in the States of Pernambuco and Alagoas, Northeastern Brazil. The estimated gene flow m was high, ranging from 2. The high genetic diversity index in these populations indicates potential for in situ genetic conservation.
We compare the results to those from an established NO2 retrieval in the visible vis spectral range from the same instrument and investigate how differences between the two are linked to the NO2 vertical profile shape in the troposphere. As expected, radiative transfer calculations for satellite geometries show that the sensitivity close to the ground is higher in the vis than in the UV spectral range. Therefore, these differences in NO2 SCDs between the two spectral ranges contain information on the vertical distribution of NO2 in the troposphere.
We combine these results with radiative transfer calculations and simulated NO2 fields from the TM5-MP chemistry transport model to evaluate the simulated NO2 vertical distribution. We investigate regions representative of both anthropogenic and biomass burning NO2 pollution. Biomass burning NO2 in contrast is often uplifted into elevated layers above the boundary layer. In tropical Africa north of the Equator, however, the biomass burning NO2 is located closer to the ground, reducing its visibility in the UV.
While not enabling a full retrieval of the vertical NO2 profile shape in the troposphere, our results can help to constrain the vertical. Opera, Imagination and Society.

My starting points are the bonds that tied Mexico, Brazil and Italy during the nineteenth century in the field of opera. The rivalry between these two musicians made us bring together and relate two rarely compared histories, two pasts, and two historiographies. High pollution events were observed during this campaign. The increase of pollution in that region leads to severe air quality degradation with regional and global implications. Reconstructed Solar-Induced Fluorescence: Solar-induced fluorescence SIF observations from space have resulted in major advancements in estimating gross primary productivity GPP.
However, current SIF observations remain spatially coarse, infrequent, and noisy. The resulting product is a proxy for ecosystem photosynthetically active radiation absorbed by chlorophyll fAPARCh. RSIF also reproduces intense productivity regions such as the U. Corn Belt contrary to typical vegetation indices and similarly to SIF.

Zazoui Glyoxal is mostly formed in our atmosphere as an intermediate product in the oxidation of non-methane volatile organic compounds NMVOC. To a lesser extent, it is also directly emitted from biomass burning events and from fossil- and bio-fuel combustion processes. Several studies have estimated its atmospheric lifetime to hours, which makes of glyoxal a good indicator for short-lived NMVOC emissions.
Glyoxal is also known to be a precursor for secondary organic aerosols and could help to reduce the gap between observations and models for organic aerosol abundances. The three absorption bands of glyoxal in the visible region allow applying the DOAS Differential Optical Absorption Spectroscopy technique to retrieve its vertical column densities from the nadir backscattered light measurements performed by the GOME -2 satellite sensor. This instrument has been launched in October on board of the METOP-A platform and is characterized by a spatial resolution of 80 km x 40 km and by a large scan-width km leading to a global coverage reached in 1.
The GOME -2 glyoxal retrieval algorithm developed at BIRA-IASB accounts for the liquid water absorption and provides geophysically sound column measurements not only over lands but also over oceanic regions where spectral interferences between glyoxal and liquid water have been shown to be significant. The a-priori glyoxal vertical distribution required for the slant to vertical column conversion is provided by the global chemical transport model IMAGESv2.
The highest glyoxal vertical column densities are mainly observed in continental tropical regions, while the mid-latitude columns strongly depend on the season with maximum values during warm months. An anthropogenic signature is also observed in highly populated regions of Asia.
Comparisons with glyoxal columns simulated with IMAGESv2 in different regions of the world generally point to a missing glyoxal source in current models. As already reported from.

Genetic diversity of Schizolobium parahyba var. Ducke Barneby , in a forest area in Brazil. Schizolobium parahyba var. It is used on a commercial scale in the timber sector, pulp and paper production, reclamation projects in degraded and landscaped areas. In this sense, the present study aimed to characterize the genetic diversity in a population of S.
The polymorphic information content performed for the ISSR markers revealed a mean of 0. One of the groups was formed with the majority of the individuals genotypes and the second with the minority 18 genotypes. The results revealed high genetic diversity in the population of S. At 7 and 21 days after the application of the herbicide, the photosynthesis, transpiration, stomatal conductance and leaf temperature were measured. The visual intoxication degree and the growth of the shoot and the root of the plants were evaluated 21 days after the application.
The photosynthesis decrease promoted by an indirect action of glyphosate represents the main reduction on the growth of plants. The decrease on the stomatal conductance, which was the most sensitive physiological variable to glyphosate, resulted in lower transpiration rates, which, consequently, caused increases on the leaf temperature. To evaluate aqueous and ethanol extract of Cassia didymobotrya leaves against immature stages of Culex quinquefasciatus.
The mortality rate of immature mosquitoes was tested in wide and narrow range concentration of the plant extract based on WHO standard protocol. The results clearly indicate that the rate of mortality was based dose of the plant extract and stage of the mosquitoes. From this study it is confirmed and concluded that Cassia didymobotrya is having active principle which is responsible for controlling Culex quinquefasciatus. The isolation of bioactive molecules and development of simple formulation technique is important for large scale implementation.
Polymorphism, genetic diversity and structure parameters were determined to characterize the differences between plants. Results show a quantitative genetic diversity value of 0. Using cluster analysis it was possible to indentify five groups. Three individuals also stand out since they presented significant divergence from the groups. The PCoA formed four groups, with three of the groups isolated from the others. This investigation showed that genetic diversity was relatively large among these individuals. In addition, the results demonstrated that RAPD markers are a useful tool for evaluating the genetic diversity and relationships among mangaba.
Accelerator, superplasticiter and silica gome by wet shotcrete; Hormigon Proyectado por Via Humeda. This project has been carried out by Geocontrol during the period September november The main target of this project was to establish a better knowledgement about the influence of the accelerator, silica fume, steel fibres and super plasticizer on the wet shotcrete properties. This project has been developed in three phases focused in three specifical targets: Effect of the accelerator, superplasticizer and silica fume dosages on shotcrete strength. Influence of steel fibres and silica fume on shotcrete characteristics.
Steel fibres dosages and type effect of shotcrete absorbed energy. The main conclusions obtained from this research are the following. Accelerators free of alkalis have a very little influence on the shotcrete strength reduction. The best results with silica fume are obtained when this product is added as a separate product, instead to be missed with other additive as superplasticizer.
Steel fibres addition improves dramatically the shotcrete post-failure characteristics. A shotcrete without steel fibres and with a strength ranged between 25 and 40 MPa absorbers Joules and another one with a steel mesh of xx6 mm absorbers Joules. Steel fibres shotcrete can reach the same energy absorption that another one reinforced with wire mesh. This research project allows to improve the knowledgement os shotcreting technique in order to use it with more efficiency than in the past.

Schoenocrambe suffrutescens Shrubby reed Diet-morphology relationship in the stream-dwelling characid Deuterodon stigmaturus Gomes , Characiformes: Characidae is partially conditioned by ontogenetic development. Full Text Available ABSTRACT We tested whether interindividual variations in diet composition within a population of Deuterodon stigmaturus can be explained by morphological differences between individuals, and whether diet-morphology relationships are dependent on the ontogenetic development.
We analyzed diet of 75 specimens sampled in a coastal stream of Southern Brazil. The most consumed food items by D. The LMMs showed that SL was positively related to consumption of terrestrial plants, whereas IL independent of SL was negatively related to aquatic invertebrates and positively related to filamentous algae.
When body sized was held constant, ML was not related to diet variation. Interindividual diet differences conditioned to body size suggest that individuals shift their trophic niche and function in the ecosystem along the ontogenetic development. Relationships between intestine length and diet composition suggest interindividual differences in foraging ability and digestibility of distinct food items.

A satellite view of riverine turbidity plumes on the NE-E Brazilian coastal zone. The analysis of the satellite image data set revealed that each river system exhibits a distinct turbidity plume dispersal pattern. The plume has lost its typical unimodal seasonal pattern of material dispersion and its turbidity has decreased due to the regulation of river flow by the dams and TSS retainance by the reservoirs.
The Caravelas Coastal System river plume is restricted to near shore shallow waters dominated by resuspension processes. During austral spring and summer when NE-E winds prevail, all plumes generally disperse southward. Short-term northward reversals may occur in winter with the passage of atmospheric cold fronts.

We examine the life, work, and legacy of Clara Haber, nee Immerwahr, who became the first woman to earn a doctorate from the University of Breslau, in In she married the chemist Fritz Haber. With no employment available for female scientists, Clara freelanced as an instructor in the continued education of women, mainly housewives, while struggling not to become a housewife herself. Her duties as a designated head of a posh household hardly brought fulfillment to her life.
The outbreak of WWI further exacerbated the situation, as Fritz Haber applied himself in extraordinary ways to aid the German war effort. The night that he celebrated the "success" of the first chlorine cloud attack, Clara committed suicide. We found little evidence to support claims that Clara was an outspoken pacifist who took her life because of her disapproval of Fritz Haber's involvement in chemical warfare.
We conclude by examining "the myth of Clara Immerwahr" that took root in the s from the perspective offered by the available scholarly sources, including some untapped ones.

Full Text Available The germination response of Ocotea pulchella Nees Mez seeds to light, temperature, water level and pulp presence is introduced. The seeds do not exhibit dormancy, they are non photoblastic, and a loss of viability in dry stored seeds can be related to a decrease in water content of the seed. The presence of the pulp and the flooded substratum influenced negatively the germination of O.
Otherwise, light and temperature probably are not limiting factors of the germination of O. The isotherms exhibited a sigmoidal pattern well described by the Weibull model in the sub-optimal temperature range. The germinability of O. Germination was not affected by fluctuations in soil moisture content in the understorey environment, whereas in gaps, germination was higher in wet soils.
Thus, the germination of this species involves the interaction of two or more factors and it cannot be explained by a single factor. The germination response of Ocotea pulchella Nees Mez seeds to light, temperature, water level and pulp presence is introduced. The optimum temperature range for germination of Ocotea pulchella seeds was 20 to 32 degrees C, the minimum or base temperature estimated was 11 degrees C and the maximum ranged between 33 and 42 degrees C. Wetlands are considered one of the most productive and ecologically valuable ecosystems on earth. We investigated the multi-temporal linkages of net ecosystem exchange NEE with the relevant climatic and ecohydrological drivers for a Florida Everglades short-hydroperiod freshwater wetland.
Hourly NEE observations and the associated driving variables during were collected from the AmeriFlux and EDEN databases, and then averaged for the four temporal scales 1-day, 8-day, day, and day. Pearson correlation and factor analysis were employed to identify the interrelations and grouping patterns among the participatory variables for each time scale. The climatic and ecohydrological linkages of NEE were then reliably estimated using bootstrapped iterations partial least squares regressions by resolving multicollinearity.
The analytics identified four bio-physical components exhibiting relatively robust interrelations and grouping patterns with NEE across the temporal scales. Further, RE and TH had a decreasing trend with the increasing time scales days. In contrast, the linkages of AD and AC components increased from 1-day to 8-day scales, and then remained relatively invariable at the longer scales of aggregation.
The estimated linkages provide insights into the dominant biophysical process components and drivers of ecosystem carbon in the Everglades. The invariant linking pattern and linkages would help to develop low-dimensional models to reliably predict CO2 fluxes from the tidal freshwater wetlands.

Brown, Jr. These densely instrumented geotechnical and structural engineering field sites continuously record both acceleration and pore pressure, with accelerometers located on the surface and at various depths below the surface, and pore pressure transducers installed at depth within the liquefiable layers.
Permanently instrumented structures for examining soil-foundation-structure interaction and a permanent cross-hole array at the sites have transformed these sites into multi-disciplinary earthquake engineering research facilities. Over the last decade, local and regional seismic activity, including multiple extremely active earthquake swarms, have produced a valuable new data set providing a unique opportunity to observe site response and the evolution of pore pressure generation with time throughout the liquefiable layer at an unprecedented level of detail.
In addition to the earthquakes provided by nature, active testing experiments using the mobile shakers from NEES UTexas and NEES UCLA have produced an equally valuable data set on both site characterization studies and soil-foundation-structure interaction. The new observations of pore pressure and acceleration with depth are providing in situ empirical evidence documenting the range of ground motion levels at which the onset of nonlinear behavior and excess pore pressure begins, augmenting previous case history data, and laboratory data from cyclic tri-axial and centrifuge testing.
The largest static pore pressure increases observed in the ' NEES ' decade of monitoring were generated by four events at the WLA site, ranging in magnitude from 4. The largest peak horizontal.

Nees extract and diterpenoids on the CYP isoforms' activities, a review of possible herb-drug interaction risks. Nees is a popular medicinal plant and its components are used in various traditional product preparations. However, its herb-drug interactions risks remain unclear. This review specifically discusses the various published studies carried out to evaluate the effects of Andrographis paniculata Burm. Nees plant extracts and diterpenoids on the CYP metabolic enzyme and if the plant components pose a possible herb-drug interaction risk.
A complete CYP inhibition assay utilizing human liver microsomes and the derivation of relevant parameters to predict herb-drug interaction risks may be necessary for these isoforms. However, based on the current studies, none of the extracts and diterpenoids exhibited CYP induction activity in human hepatocytes or human-derived cell lines.
It is crucial that a well-defined experimental design is needed to make a meaningful herb-drug interaction prediction. Long-term impacts of peatland restoration on the net ecosystem exchange NEE of blanket bogs in Northern Scotland. Unmanaged peatlands represent an important long-term C sink and thus play an important part of the global C cycle. The Flow Country of Northern Scotland is the largest area of contiguous blanket bog in the UK, and one of the biggest in Europe, covering an area in excess of km2 and plays a key role in mediating regional atmospheric exchanges of greenhouse gases GHGs such as carbon dioxide CO2 , and water vapour H2O.
However, these peatlands underwent significant afforestation in the s, when over km2 of blanket bog were drained and planted with Sitka spruce Picea sitchensis and Lodgepole pine Pinus contorta. This resulted in modifications to hydrology, micro-topography, vegetation and soil properties all of which are known to influence the production, emission and sequestration of key GHGs. Since the late s restoration work has been carried out to remove forest plantations and raise water tables, by drain blocking, to encourage the recolonisation of Sphagnum species and restore ecosystem functioning.
Here, we report findings of NEE and its constituent fluxes, GPP and Reco, from a study investigating the impacts of restoration on C dynamics over a chronosequence of restored peatlands. The research explored the role of environmental variables and microtopography in modulating land-atmosphere exchanges, using a multi-scale sampling approach that incorporated eddy covariance measurements with dynamic flux chambers.
Key age classes sampled included an undrained peatland; an older restored peatland 17 years old ; and a more recently restored site 12 years old. The oldest restored site showed the strongest uptake of C, with an annual assimilation rate of g C m-2 yr-1 compared to assimilation rates of g C m-2 yr-1 and g C m-2 yr-1 from the younger restored site and.

Andrographolides, the diterpene lactones, are major bioactive phytochemicals which could be found in different parts of the medicinal herb Andrographis paniculata.
A number of such compounds namely andrographolide AG , neoandrographolide NAG , and deoxy,didehydroandrographolide DDAG have already attracted a great deal of attention due to their potential therapeutic effects in hard-to-treat diseases such as cancers and HIV. Recently, they have also been considered as substrates for the discovery of novel pharmaceutical compounds.
Nevertheless, there is still a huge gap in knowledge on the genetic pattern of the biosynthesis of these bioactive compounds. Hence, the present study aimed to investigate the genetic mechanisms controlling the biosynthesis of these phytochemicals using a diallel analysis. The high performance liquid chromatography analysis of the three andrographolides in F1 progenies confirmed that the biosynthesis of these andrographolides was considerably increased via intraspecific hybridization. Furthermore, the preponderance of non-additive gene actions was affirmed in the enhancement of the three andrographolides contents.
The consequence of this type of gene action was the occurrence of high broad-sense and low narrow-sense heritabilities for the above mentioned andrographolides. The prevalence of non-additive gene action suggests the suitability of heterosis breeding and hybrid seed production as a preferred option to produce new plant varieties with higher andrographolide contents using the wild accessions of A. Moreover, from an evolutionary point of view, the occurrence of population bottlenecks in the Malaysian accessions of A.
