    Every part of the world is characterized by his own climatological peculiarities, and sometimes some restricted areas can be influenced by local, singular, characteristical metereological phenomena. Trieste, capital of the region Friuli Venezia Giulia, and the Karst ( northeastern Italy) are included in this category. Since the old age it has been narrated the "raids" caused by the Bora, strong dry and cold north eastern wind that, with one of his most northern branch, which born in the karstic inland near Postumia (Slovenia), affects the Karst plateau and the Gulf of Trieste. In literature we can find how on September 5th, 394 a.C. the "miraculous wind" Bora has been decisive for the defeat of Arbogaste (West Roman Empire) in the Vipavska valley; he was with his army against the wind in the battle whereas the troops of the Catholic Emperor Teodosio (East Roman Empire) has been able to through their darts further thank to the wind. The fairy tales about "Bora" and "Borino" are part of the local literature since many centuries, whereas in the XX Century we can find images, postcards and books concerning the tempestuous wind of Trieste. When television born, developed a new way to communicate the deeds of Bora thanks to some extreme events occurred among 30s and 50s which contributes to increase his mith. The goal of this work is to retrace the history of Bora in the words of the common people rather than the science in order to understand how his legend has grown during the ages. Now, in the age of internet, a new way of telling the Bora adventures is born.

    Ethnographic evidence indicates that bora (initiation) ceremonial sites in southeast Australia, which typically comprise a pair of circles connected by a pathway, are symbolically reflected in the Milky Way as the 'Sky Bora'. This evidence also indicates that the position of the Sky Bora signifies the time of the year when initiation ceremonies are held. We use archaeological data to test the hypothesis that southeast Australian bora grounds have a preferred orientation to the position of the Milky Way in the night sky in August, when the plane of the galaxy from Crux to Sagittarius is roughly vertical in the evening sky to the south-southwest. We accomplish this by measuring the orientations of 68 bora grounds using a combination of data from the archaeological literature and site cards in the New South Wales Aboriginal Heritage Information Management System database. We find that bora grounds have a preferred orientation to the south and southwest, consistent with the Sky Bora hypothesis. Monte Carlo statis...

    The Bora wind field is characterised by strong vorticity and divergence. Several numerical experiments, in which an oceanographic model was forced with northeasterly winds having climatological alongshore variability, were performed in order to study the influence of spatial variability in the bora wind field on the surface currents in the northern Adriatic. Numerical model results showed that during bora episodes with lower speeds and fast offshore decay surface currents along transect Rovinj - Po River are predominantly in the downwind direction. On the other hand, during bora episodes with strong intensity and slow offshore decay, a cyclonic gyre due to the pronounced bora alongshore variability is formed in the northernmost part of the Adriatic Sea and the studied transect is influenced by the counter currents. Moreover, bora having a high speed and a short offshore range produces the same effect in the eastern part of the Rovinj - Po River transect as low-speed bora characterised by slow offshore decay. Eulerian current measurements performed in the northern Adriatic during bora episodes characterised by different synoptic conditions supported the numerical model findings. Surface currents during the bora episode of 8-11 February 1984 were directed downwind, whereas during the episode of 12-19 February 1984 they were directed upwind. The first episode was characterised by a deep bora layer with cyclonic activity over the western Mediterranean and Genoa Bay, whereas the second one was accompanied by temperature inversion and a southwesterly tropospheric wind above a shallow bora layer. According to the hydraulic theory developed by Smith (1985), an observed descent of isentropes during the second bora episode led to the stronger acceleration in the bora layer and its larger offshore extent. Different offshore bora decays during studied events were confirmed by a comparison of the wind data originating from the meteorological stations positioned on the opposite

    This paper deals with the bora wind effect on the Adriatic Sea circulation as simulated by a 3-D numerical code (the DieCAST model). The main result of this forcing is the formation of intense upwelling along the eastern coast in agreement with previous theoretical studies and observations. Different numerical experiments are discussed for various boundary and initial conditions to evaluate their influence on both circulation and upwelling patterns.

    The Vipava valley in Slovenia is well known for the appearance of strong, gusty North-East Bora winds, which occur as a result of air flows over an adjacent orographic barrier. There are three prevailing wind directions within the valley which were found to give rise to specific types of atmospheric structures. These structures were investigated using a Mie scattering lidar operating at 1064 nm, which provided high temporal and spatial resolution backscatter data on aerosols, which were used as tracers for atmospheric flows. Wind properties were monitored at the bottom of the valley and at the rim of the barrier using two ultrasonic anemometers. Twelve time periods between February and April 2015 were selected when lidar data was available. The periods were classified according to the wind speed and direction and investigated in terms of appearance of atmospheric structures. In two periods with strong or moderate Bora, periodic atmospheric structures in the lidar data were observed at heights above the mountain barrier and are believed to be Kelvin-Helmholtz waves, induced by wind shear. No temporal correlation was found between these structures and wind gusts at the ground level. The influence of the wind on the height of the planetary boundary layer was studied as well. In periods with low wind speeds, the vertical evolution of the planetary boundary layer was found to be governed by solar radiation and clouds. In periods with strong or moderate Bora wind, convection within the planetary boundary layer was found to be much weaker due to strong turbulence close to the ground, which inhibited mixing through the entire layer.

    The synthesis and degradation of hBora is important for the regulation of mitotic entry and exist. In G 2 phase, hBora can complex with Aurora A to activate Plk1 and control mitotic entry. However, whether the post-translational modification of hBora is relevant to the mitotic entry still unclear. Here, we used the LC-MS/MS phosphopeptide mapping assay to identify 13 in vivo hBora phosphorylation sites and characterized that GSK3β can interact with hBora and phosphorylate hBora at Ser274 and Ser278. Pharmacological inhibitors of GSK3β reduced the retarded migrating band of hBora in cells and diminished the phosphorylation of hBora by in vitro kinase assay. Moreover, as well as in GSK3β activity-inhibited cells, specific knockdown of GSK3β by shRNA and S274A/S278 hBora mutant-expressing cells also exhibited the reduced Plk1 activation and a delay in mitotic entry. It suggests that GSK3β activity is required for hBora-mediated mitotic entry through Ser274 and Ser278 phosphorylation.

    Bora wind is a phenomenon observed on the lee side of mountain chains, where the cold air-masses flowing over the barrier cause strong downslope winds. The relief profile of the SW Slovenia, which within 30 km of the coastal line first rises to a Karst plateau (300 m above sea level), then falls into the Vipava valley (100 m a.s.l.) and rises again to a mountainous barrier with maximum altitudes of about 1500 m a.s.l., creates an ideal setting for the occurrence of downslope winds in the Vipava valley. The occurrence of strong winds is correlated to the presence of cold NE air-flows in the higher, stably stratified layer, flowing over the SW-oriented orographic barrier, and warmer air on the lee side of the mountain range. These conditions lead to the flow of cold air from behind the barrier sinking into the valley bellow, generating very gusty and strong winds. Our data sample includes wind and gust speed measurements in the period from 27 January to 24 April 2012, which was selected due to strong Bora wind outbursts at that time. Wind speeds were measured using 15 wind sensors, out of which 5 were dedicated cup anemometers, positioned 4 meters above the ground and arranged in a two lines perpendicular to the barrier, line A consisting of 3 and line B of 2 instruments. The remaining wind sensors were ultrasonic, positioned at various heights above the ground at 10 different locations along the Vipava valley. The obtained gust speed measurements were analyzed in order to evaluate the frequency distribution of the wind gusts. In order to eliminate longer time intervals with light- or no wind, which can not be characterized as Bora and do not add any information to the gust frequency analysis, Fourier transform of the data was made for short time periods, taking into account single Bora wind outbursts only. Wind speed measurements were studied separately for each instrument line. In the line A, the first instrument was positioned in an elevated up-wind location on

  14. Bora and Aurora-A continue to activate Plk1 in mitosis.

    Polo-like kinase-1 (Plk1) is required for proper cell division. Activation of Plk1 requires phosphorylation on a conserved threonine in the T-loop of the kinase domain (T210). Plk1 is first phosphorylated on T210 in G2 phase by the kinase Aurora-A, in concert with its cofactor Bora. However, Bora was shown to be degraded prior to entry into mitosis, and it is currently unclear how Plk1 activity is sustained in mitosis. Here we show that the Bora-Aurora-A complex remains the major activator of Plk1 in mitosis. We show that a small amount of Aurora-A activity is sufficient to phosphorylate and activate Plk1 in mitosis. In addition, a fraction of Bora is retained in mitosis, which is essential for continued Aurora-A-dependent T210 phosphorylation of Plk1. We find that once Plk1 is activated, minimal amounts of the Bora-Aurora-A complex are sufficient to sustain Plk1 activity. Thus, the activation of Plk1 by Aurora-A may function as a bistable switch; highly sensitive to inhibition of Aurora-A in its initial activation, but refractory to fluctuations in Aurora-A activity once Plk1 is fully activated. This provides a cell with robust Plk1 activity once it has committed to mitosis.

    Investigations of major accidents show that technical, human, operational, as well as organisational factors influence the accident sequences. In spite of these facts, quantitative risk analyses of offshore oil and gas production platforms have focused on technical safety systems. This paper presents a method (called BORA-Release) for qualitative and quantitative risk analysis of the platform specific hydrocarbon release frequency. By using BORA-Release it is possible to analyse the effect of safety barriers introduced to prevent hydrocarbon releases, and how platform specific conditions of technical, human, operational, and organisational risk influencing factors influence the barrier performance. BORA-Release comprises the following main steps: (1) development of a basic risk model including release scenarios, (2) modelling the performance of safety barriers, (3) assignment of industry average probabilities/frequencies and risk quantification based on these probabilities/frequencies, (4) development of risk influence diagrams, (5) scoring of risk influencing factors, (6) weighting of risk influencing factors, (7) adjustment of industry average probabilities/frequencies, and (8) recalculation of the risk in order to determine the platform specific risk related to hydrocarbon release. The various steps in BORA-Release are presented and discussed. Part II of the paper presents results from a case study where BORA-Release is applied.

    This paper presents results from a case study carried out on an offshore oil and gas production platform with the purpose to apply and test BORA-Release, a method for barrier and operational risk analysis of hydrocarbon releases. A description of the BORA-Release method is given in Part I of the paper. BORA-Release is applied to express the platform specific hydrocarbon release frequencies for three release scenarios for selected systems and activities on the platform. The case study demonstrated that the BORA-Release method is a useful tool for analysing the effect on the release frequency of safety barriers introduced to prevent hydrocarbon releases, and to study the effect on the barrier performance of platform specific conditions of technical, human, operational, and organisational risk influencing factors (RIFs). BORA-Release may also be used to analyse the effect on the release frequency of risk reducing measures.

    On the basis of two-month measurements of the bora wind at Senj, Croatia, with a 1 s temporal resolution, properties of the bora turbulence are inspected using the records of three bora episodes. The spectrum is divided into two parts: high-frequency turbulence (periods less than 1 min) and the low-frequency part (periods between 1 and 10 min) where pulsations appear. We have found that the high-frequency turbulence is generated locally by surface roughness and local wind shear. On the other hand, the low-frequency turbulence, i.e. the pulsations, seems to be independent of the local properties and can therefore be treated as an organized non-local effect. This is in accordance with the studies of the pulsations in the Boulder downslope windstorm. (orig.)

    Mesoscale meteorological phenomena, such as Novaya Zemlya bora and polar cyclones, have been studied based on the respective signatures in synthetic aperture radar (SAR) images of the sea surface using remote sensing methods. The local bora covers both coastal and open-sea zones of the Barents Sea to the west of Novaya Zemlya and can lead to catastrophic consequences in coastal waters of the archipelago. Another interesting and hardly predictable phenomenon is polar cyclones. The development of especially intensive and catastrophic polar cyclones can be traced using multisensor and multispectral imagery. It has been shown that the application of spaceborne SARs and optical sensors enables real time detection, forecast, and monitoring of Novaya Zemlya bora and polar cyclones in the Barents Sea, giving ground for their detail research.

  1. Cdk1 Phosphorylates SPAT-1/Bora to Promote Plk1 Activation in C. elegans and Human Cells

    Full Text Available The conserved Bora protein is a Plk1 activator, essential for checkpoint recovery after DNA damage in human cells. Here, we show that Bora interacts with Cyclin B and is phosphorylated by Cyclin B/Cdk1 at several sites. The first 225 amino acids of Bora, which contain two Cyclin binding sites and three conserved phosphorylated residues, are sufficient to promote Plk1 phosphorylation by Aurora A in vitro. Mutating the Cyclin binding sites or the three conserved phosphorylation sites abrogates the ability of the N terminus of Bora to promote Plk1 activation. In human cells, Bora-carrying mutations of the three conserved phosphorylation sites cannot sustain mitotic entry after DNA damage. In C. elegans embryos, mutation of the three conserved phosphorylation sites in SPAT-1, the Bora ortholog, results in a severe mitotic entry delay. Our results reveal a crucial and conserved role of phosphorylation of the N terminus of Bora for Plk1 activation and mitotic entry.

    The dynamics, structure and temporal evolution of a severe Adriatic bora, which occurred during 14 and 15 November 2004 was inspected. Numerical simulation of the investigated episode was performed by the mesoscale model MM5. The model was validated against radiosonde data and wind data from one automatic meteorological station and three ultrasonic anemometers. Two anemometers where located in the region extremely favorable for the bora occurrence (Senj and Vratnik Pass), while the third one was placed in the mainland (Zagreb-Horvatovac). The model reproduced well the onset and the strength of the investigated bora, as well as the establishment of bora-induced potential vorticity (PV) banners. On the other hand, surface turbulent kinetic energy (TKE) was poorly predicted. Inspection of gap wind characteristics indicated the absence of strong dissipation in the flow through a mountain pass, which gives rise to a horizontally elongated jet. Appearance of wave breaking in the lee of a mountain peak leads to the creation of a mountain wake. Shear lines between individual jets and wakes created in this way are then responsible for the generation of PV banners. Also, the ability of the model to predict hourly wind gusts was validated using a recently developed method. (orig.)

    Aurora-A kinases are highly conserved mitotic kinases required for cell division. The regulation of Aurora-A activity is less highly conserved and currently poorly understood. Work by Knoblich and coworkers in this issue of Developmental Cell identifies the conserved protein, Aurora Borealis (Bora), as a key regulator of Aurora-A activity during mitosis.

    Full Text Available Purpose: The purpose of this research was to established new polysaccharide for the colon targeted drug delivery system, its formulation and in vitro and in vivo evaluation. Methods: Microspheres containing pectin and bora rice were prepared by ionotropic gelation technique using zinc acetate as cross linking agent and model drug used was glipizide. A 32 full factorial design was employed to study the effect of independent variables, polymer to drug ratio (A, and concentration of cross linking agent (B on dependent variables, particle size, swelling index, drug entrapment efficiency and percentage drug release. Results: Results of trial batches indicated that polymer to drug ratio and concentration of cross linking agent affects characteristics of beads. Beads were discrete, spherical and free flowing. Beads exhibited small particle size and showed higher percentage of drug entrapment efficiency. The optimized batch P2 exhibited satisfactory drug entrapment efficiency 68% and drug release was also controlled for more than 24 hours. The polymer to drug ratio had a more significant effect on the dependent variables. In vivo gamma scintigraphy study of optimized pectin-bora rice beads demonstrated degradation of beads whenever they reached to the colon. Conclusion: Bora rice is potential polysaccharide for colon targeted drug delivery system.

    Mitosis is orchestrated by several protein kinases including Cdks, Plks and Aurora kinases. Despite considerable progress toward understanding the individual function of these protein kinases, how their activity is coordinated in space and time during mitosis is less well understood. In a recent article published in the Journal of Cell Biology, we show that CDK-1 regulates PLK-1 activity during mitosis in C. elegans embryos through multisite phosphorylation of the PLK-1 activator SPAT-1 (Aurora Borealis, Bora in human). SPAT-1 variants mutated on CDK-1 phosphorylation sites results in severe delays in mitotic entry, mimicking embryos lacking spat-1 or plk-1 function. We further show that SPAT-1 phosphorylation by CDK-1 promotes its binding to PLK-1 and stimulates PLK-1 phosphorylation on its activator T-loop by Aurora A kinase in vitro. Likewise, we find that phosphorylation of Bora by Cdk1 promotes phosphorylation of human Plk1 by Aurora A suggesting that this mechanism is conserved in humans. These results indicate that Cdk1 regulates Plk1 by boosting its kinase activity. Here we discuss these recent findings and open questions regarding the regulation of Plk1/PLK-1 by Cdk1/CDK-1 and Bora/SPAT-1.

    A COAMPS (TM) nonhydrostatic numerical model with a higher order turbulence closure scheme is used to study the effect of the sea-surface temperature (SST) on the idealized nonlinear flow over an idealized mountain in the presence of rotation. The low-level jet (LLJ) that develops at both flanks of the mountain is intensified by the Coriolis effect on the northern flank for a westerly flow. Shooting flow develops down the slope ending over the sea while resembling a hydraulic jump. This is considered as bora (bura) like flow. The front is related to the abrupt slowdown of the shooting flow through the hydraulic jump. Seven different idealized cases are addressed, the control run, nearly linear case with Fr = 1.2, and the cases with the SST 10 K colder, and 2.5 K, 5 K, 7.5 K and 10 K warmer than the control run. The maximum wind speeds in the shooting flow and the LLJs are around two times higher than the background wind speeds. The interplay of SST effects and the effects of the asymmetric lee-side vortices modify the location and the shape of the bora front which is found not to be parallel with the shoreline. The front is not stationary in time but exhibits vibrations which are more pronounced at the southern flank associated with the weaker LLJ. (orig.)

  9. The onset of a severe summer bora episode near Oštarijska Vrata Pass in the Northern Adriatic

    A severe bora episode which lasted from 22 to 25 July 2012 has been selected for the 3D numerical model analysis of the start of the bora near the Oštarijska Pass in the Northern Adriatic of Croatia. The 10-m wind analysis shows that the gap flow turns and rotates in the central part of the Vir Sea at the start of bora. The MM5 model validation shows that the modelled wind matches well the automatic stations measurements and the validation of the vertical profiles shows that the model adequately captured the basic thermodynamic and flow structure during the bora episode. The vertical cross sections show the turning of the horizontal wind in the first 500-800 m over a relatively small area over the Vir Sea. The analysis implies that the wind turning can be attributed to the impact of the Etesian windflow, the frontal passage and the positions of the outer islands and coastal area. The analysis of the horizontal vorticity of the surface wind shows vorticity banners downwind of the gap with high vorticity values, up to 4 × 10-5 s-1, in the central part of the Vir Sea. A secondary northeastern vorticity maximum is developed due to the orography of the coastal area and the rotational windflow.

  10. Combined observations of a Bora event in the Adriatic Sea by means of ETA model and SAR data

    The Bora is a cold, strong, low level wind which blows from the northeast along the Adriatic coast (Ivančan-Picek and Tutiš, 1996, Lazić and Tošić, 1998, Morelli and Berni, 2002). Bora wind is known to have multiple surface wind jets linked to the orography of the Dinaric Alps and alters significantly the sea status (Cesini et al, 2004). A recent version of the Eta model (Mesinger et al, 2012), which is a three-dimensional, primitive equation, grid-point model, was used to represent the low level wind field corresponding to the Bora event occurred at the beginning of February 2012. Numerical simulations, initialized by ECMWF data, were performed with different horizontal resolutions (approximately 20 km and 4 km) and domain extent. The numerical simulations describe the atmospheric conditions of the period and reveal the spatial structure of the wind, in good agreement with the understanding as well as the observational knowledge of the bora. In addition, the wind speed and direction was estimated on the ASAR images. Wind directions were obtained by exploiting a novel technique based on the use of 2D continuous wavelets (Zecchetto and De Biasio, 2001, 2008). Then, the retrieved wind directions were used to estimate the wind speed from the ASAR NRCS by inverting the semi-empirical backscatter model CMOD-5 (Hersbach, 2005). The ASAR observed morphology, wake patterns and, where present, dual-jet structure of the Bora wind were analysed for 2 and 5 February at the two different Eta resolution scales. Results of the comparisons between Eta prediction and ASAR data will be shown.

  11. A new model evaluating Holocene sediment dynamics: Insights from a mixed carbonate-siliciclastic lagoon (Bora Bora, Society Islands, French Polynesia, South Pacific)

    Mixed carbonate-siliciclastic lagoons of barrier reefs provide great potential as sedimentary archives focusing on paleoenvironmental and paleoclimatic changes as well as on event deposition. Sediment sources include lagoonal carbonate production, the marginal reef and the volcanic hinterland. Mixed carbonate-siliciclastic continent-attached coastal lagoons have been intensively studied, however, their isolated oceanic counterparts have been widely disregarded. Here, we present a new model of Holocene sediment dynamics in the barrier-reef lagoon of Bora Bora based on sedimentological, paleontological, geochronological and geochemical data. The lagoonal succession started with a Pleistocene soil representing the Lowstand Systems Tract. As the rising Holocene sea inundated the carbonate platform, peat accumulated locally 10,650-9400 years BP. Mixed carbonate-siliciclastic sedimentation started ca. 8700-5500 years BP and represents the Transgressive Systems Tract. During that time, sediments were characterized by relatively coarse grain size and contained high amounts of terrestrial material from the volcanic hinterland as well as carbonate sediments mainly produced within the lagoon. Siliciclastic content decreases throughout the Holocene. After the rising sea had reached its modern level, sand aprons formed between reef crest and lagoon creating transport pathways for reef-derived material leading to carbonate-dominated sedimentation ca. 6000-3000 years BP during the Highstand Systems Tract. However, mainly fine material was transported and accumulated in the lagoon while coarser grains were retained on the prograding sand apron. From ca. 4500-500 years BP, significant variations in grain-size, total organic carbon as indicator for primary productivity, Ca and Cl element intensities as qualitative indicators for carbonate availability and lagoonal salinity are seen. Such patterns could indicate event (re-)deposition and correlate with contemporaneous event deposits

    The effects of repeated cycled crystallization on the digestibility and molecular structure of glutinous Bora rice starch were investigated. Temperature cycle 4/45°C; cycle duration 5d; time interval of cycles 24h; and starch to water ratio 1:2 were found to be optimum for SDS (slow digestible starch) product development. The SDS content increased from 18.01±2.11% to 82.81±2.34%. An increase in the resistance to digestion, crystallinity, molecular weight, polydispersity and molecular order was observed in the optimal SDS product. Notably, the FT-IR peak at 947cm(-1) and XRD peaks at 2θ≈13° and 20° in the optimal SDS product indicated the formation of V-type complexes even without the presence of co-polymers. Birefringence studies showed a loss of typical Maltese cross in the SDS product and revealed a reorientation of crystalline structures within starch granules, suggestive of imperfect crystallite development.

    In this paper we describe the design of the re-configurable front-end boards (BORA boards) for the 82944 channel RICH-1 (Ring Imaging CHerenkov) of the Compass Collaboration (NA58). The front-end electronics controls the sample-and-hold operation after the arrival of an event trigger, acquires the analog voltages from the pre-amp VLSI and converts them into 10 bits at a rate of 20 Ms/s per analog channel. The digitized analogue values are then written into FIFOs. A subsequent operation compares the readings of each and every channel with corresponding programmable thresholds, and transmits those values larger than the threshold, together with the channel number, through an optical fiber to subsequent processing stages of the acquisition system. The overall operation of the board is controlled and supervised by a fast DSP. The availability of local intelligence allows the board to present innovative features such as to be part of a computer network that connects several similar boards of the detector with a PC...

    Full Text Available Cinco caracteres morfoagronômicos, avaliados em sete linhagens de abóbora (Cucurbita moschata, foram submetidos à estimação de parâmetros genéticos e à análise de correlações simples e canônicas. As características foram avaliadas em um experimento em blocos ao acaso, com três repetições e parcelas de seis plantas. Os caracteres peso médio de fruto e comprimento longitudinal externo apresentaram herdabilidade superiores a 80% e índice de variação superior à unidade, demonstrando que a aplicação de métodos simples de melhoramento como, por exemplo, a seleção massal, poderão resultar em bons ganhos de seleção. Com relação às correlações simples, para a maioria dos pares de características (80% as correlações genotípicas foram maiores que as fenotípicas e de ambiente. As correlações simples e canônicas demonstraram que o aumento no peso médio de frutos foi acompanhado de aumento na espessura da polpa e nos comprimentos longitudinal e transversal. Por outro lado, aumento no número médio de frutos apresentou correlação significativa com redução no comprimento longitudinal e na espessura de polpa e com incremento do comprimento transversal. Na população em estudo, genótipos de interesse comercial, contendo fruto de menor tamanho e polpa espessa, poderão ser obtidos com o emprego da técnica do índice de seleção, por sobrepujar o sentido das correlações.Five morphological and agronomic characteristics were evaluated in seven squash lines. The experiment was carried out in completely randomized blocks, with three replications, and six-plant plots. Genetic parameters, as well as simple and canonic correlations were estimated. Heritability for average fruit weight and external longitudinal length were higher than 80%, with a variation index higher than one. Thus, application of simple breeding methods, such as mass selection, will result in good selection gains. Concerning simple correlations, most

    Full Text Available The tip pruning stimulates the emission of lateral shoots, thus can produce higher number of flowers, fruits and seeds. This work aimed to evaluate the effect of apex pruning on fruit and seed production in pumpkin. The treatments consisted of plants without pruning, with pruning in the sixth, eighth and tenth node of main stem. The experimental design was a randomized block, with six replications. It was studied a line of pumpkin of the Germplasm Bank of the Universidade Estadual Paulista/Faculdade de Ciências Agronômicas. The characteristics evaluated were: number of branches per plant and fruit position in branches of the plant production (number and weight of fruits per plant, fruit yield, fruit average weight, fruit length and diameter, seed weight per fruit, seed yield and quality (germination test, first count, thousand seed weight, emergence, speed of emergence and accelerated aging. There was a significant difference only for number of secondary branches per plant and thousand seed weight, with larger values for plants that have not been pruned. It was obtained high average of germination (94% and good fruit (16.9 t ha-1 and seed (148 kg ha-1 yield. The apex pruning does not influence the production of fruits and seeds, as well as the physiological seed quality in pumpkin =A poda apical estimula a emissão de brotos laterais, com isso pode haver maior formação de flores e frutos e, consequentemente, maior número de sementes.

Assim, apesar de haver variabilidade genética dentro dos acessos, a maior proporção da variabilidade em C. pepo encontra-se distribuída entre as diferentes variedades crioulas. A variação dentro dos acessos é explicada pela alogamia da espécie, pelo intercâmbio de sementes das variedades crioulas entre os agricultores e também pelos mesmos cultivarem mais de uma variedade de Cucurbita na mesma área.Among the five cultivated species of pumpkins, Cucurbita pepo has the highest variability for fruit characteristics, such as color, shape and size.

Apesar de não ter havido efeito estatístico sobre a produtividade, houve redução linear para a maioria das características do fruto (comprimento, diâmetro e massa com o aumento da idade das mudas. Assim, observou-se que mudas mais velhas, com a parte aérea mais desenvolvida e as preferidas por alguns produtores por seu sistema radicular compacto e a maior facilidade para serem transplantadas, podem reduzir a qualidade de abóbora.The purpose of this research was to study the effect of tray type and seedling age in the production of squash, hybrid Atlas. Two tray types (72 and 128 cells and four seedling ages (19, 24, 29 and 34 days after sowing were evaluated in randomized blocks design, with six replication and five plants per plot. Fruit yield, average fruit weight and fruit dimensions (total length, neck and seed cavity length and diameter were evaluated. Besides absence of significant statistical difference in fruit yield, for most of fruit characteristics (average weight, length and diameter a linear reduction was observed in aging seedling. Therefore, older seedlings with more developed shoots, and which are preferred by some producers due to their compact radicular system and easiness to transplant, may present lower squash quality.

Foram utilizadas as seguintes coberturas: cera de carnaúba Fruit Wax H2 (18%, emulsão de resinas Fruit Wax M-AC (18% e cera de carnaúba Megh Wax ECF-124 (18%; tomates sem cera serviram de controle. Foram utilizados 40 frutos por tratamento em delineamento inteiramente casualizado. Após a limpeza e aplicação das ceras, os frutos foram armazenados a 12,5°C e 25°C e 90% de umidade relativa. Análises para perda de massa fresca (%, coloração e qualidade foram realizadas durante quinze dias. No final do período de armazenagem, os frutos foram avaliados quanto à firmeza, pH, concentração de sólidos solúveis, vitamina C e acidez. Foi realizada também análise sensorial para frutos armazenados nas duas diferentes temperaturas. O tratamento com Megh Wax ECF-124 proporcionou menor perda de massa e frutos mais firmes em ambas as temperaturas. Tomates tratados com Fruit Wax M-AC e Megh Wax ECF-124 apresentaram maior porcentagem de frutos apropriados ao consumo. Não houve diferença significativa entre os tratamentos quanto à coloração e análises químicas, exceto para os frutos cobertos com Fruit Wax M-AC, que apresentaram menor teor de vitamina C em ambas as temperaturas e maior pH a 25°C. As ceras Fruit Wax M-AC e Megh Wax ECF-124 não interferiram no sabor e no odor dos frutos. A aplicação de cera contribui para uma diminuição na perda de massa e decréscimo no número de frutos descartados devido a danos físicos e podridões, sendo que Megh Wax ECF-124 é mais eficiente na manutenção da qualidade de tomates de mesa.This study aimed at evaluating the effect of edible coatings on tomato cv.

    Full Text Available A abertura de flores femininas na abóbora híbrida 'Tetsukabuto' concentra-se num período de três a quatro semanas. Este curto período de florescimento indica que uma polinização deficiente pode ocasionar grande comprometimento da produção de frutos. Este trabalho foi conduzido com o objetivo de avaliar o efeito de concentrações do fitorregulador alfa-naftalenoacetato de sódio (ANA-Na, pulverizado em flores abertas femininas, na frutificação e crescimento de frutos da abóbora 'Tetsukabuto'. O experimento foi conduzido em Lages, SC, na safra 1992/1993, seguindo o delineamento em blocos casualizados, com três repetições. A parcela foi constituída de cinco covas de 'Tetsukabuto' e uma da polinizadora Cucurbita maxima, em espaçamento de 3 x 1 m, com duas plantas/cova. Os tratamentos utilizados foram testemunha (polinização natural e 150, 300, 450, 600 e 750 mg·L-1 de ANA-Na. Nos tratamentos com ANA-Na, evitou-se a polinização natural isolando-se as flores com sacos de papel. Avaliou-se percentagem de frutificação, peso, comprimento e diâmetro dos frutos e peso, espessura, rendimento e sólidos totais da polpa. Apenas a dose de 750 mg·L-1 do hormônio reduziu a percentagem de frutificação. Os frutos obtidos por tratamento com ANA-Na apresentaram crescimento similar ao dos frutos obtidos por polinização.Anthesis of female flowers of 'Tetsukabuto' squash occurs within three to four weeks. A deficient pollination during this short flowering period may reduce the yield. The sodium salt of alfa-naphthaleneacetic acid (Na-NAA can be used to improve fruit set when pollination is deficient.

    Full Text Available A abóbora é uma hortaliça que apresenta grande importância na agricultura familiar no nordeste brasileiro. Muitas comunidades têm encontrado dificuldades na comercialização de todos os frutos produzidos, em função da grande variabilidade fenotípica, que nem sempre atende às exigências do mercado. O estudo de parâmetros genéticos é importante para fornecer informações na implantação e condução de um programa de melhoramento. Desta forma, o objetivo do trabalho foi estimar parâmetros genéticos, fenotípicos e ambientais para caracteres morfológicos e agronômicos em abóbora. Foram estudados sete genótipos de abóbora para os anos agrícolas de 2008 e 2009, considerando como aleatório o efeito dos anos e fixo o efeito dos genótipos. As variáveis analisadas foram comprimento e largura do fruto, espessura da polpa na região do pedúnculo, do meio e da parte inferior do fruto, altura e largura da cavidade interna do fruto, rendimento de frutos, número de sementes por fruto e massa de 100 sementes. A variável que apresentou os maiores coeficientes de variação genética (25,10 e 41,32 nos dois anos agrícolas, respectivamente foi a espessura da polpa no pedúnculo. A herdabilidade foi acima de 90% para as variáveis comprimento dos frutos (98 e 97%, largura dos frutos (98 e 95%, espessura da polpa na região do pedúnculo (98 e 96%, e altura da cavidade interna do fruto (99 e 97%, nos dois anos agrícolas avaliados. Para a relação CVg/CVe, foram encontrados valores maiores que 1,0 para os caracteres comprimento e largura do fruto, espessura da polpa na região do pedúnculo e do meio, largura e altura da cavidade interna dos frutos, rendimento de frutos, número de sementes por fruto e massa fresca de 100 sementes.

    Full Text Available A baixa produção de sementes híbridas de abóbora obtida em nossas condições deve-se provavelmente aos métodos de produção pouco eficientes. A quantidade de pólen transferido naturalmente ou artificialmente entre os parentais pode afetar não só a produção como também a qualidade das sementes híbridas. Neste estudo, utilizou-se a polinização manual, a qual constou de cinco tratamentos relacionados com a quantidade de pólen do progenitor masculino para polinizar uma única flor feminina: um quarto da quantidade de pólen de uma flor; metade da quantidade de pólen de uma flor; a quantidade de pólen de uma flor; a quantidade de pólen de duas flores, e a quantidade de pólen de quatro flores masculinas. O delineamento experimental adotado foi em blocos ao acaso, com três repetições e dezoito plantas por parcela. O aumento da quantidade de pólen aplicada aumentou a produção de sementes por fruto e consequentemente a produção de sementes por área. A qualidade fisiológica das sementes praticamente não foi afetada entre os tratamentos, embora foi observada uma menor germinação das sementes obtidas em frutos provenientes de flores polinizadas com 1/4 de pólen.The low production of squash hybrid seeds obtained in our conditions is probably due to the inefficient production methods. The amount of pollen transferred naturally or artificially between the two parents may affect not only the hybrid seed production but also the seed quality of squash. In this study, flowers were manually pollinated using five amounts of pollen to pollinate one female flower: 1/4 of pollen from one flower; half of the amount of pollen from one flower; pollen of one flower; pollen of two flowers and pollen of four flowers. The randomized complete block design was adopted, with three replications and eighteen plants per plot. The increasing pollen amount affected significantly seed yield per fruit and seed yield per area, but did not influence

    Specific boronic acids are generally powerful tetrahedral intermediate/transition state analogue inhibitors of serine amidohydrolases. This group of enzymes includes bacterial β-lactamases and DD-peptidases where there has been considerable development of boronic acid inhibitors. This paper describes the synthesis, determination of the inhibitory activity, and analysis of the results from two α-(2-thiazolidinyl) boronic acids that are closer analogues of particular tetrahedral intermediates involved in β-lactamase and DD-peptidase catalysis than those previously described. One of them, 2-[1-(dihydroxyboranyl)(2-phenylacetamido)methyl]-5,5-dimethyl-1,3-thiazolidine-4-carboxylic acid, is a direct analogue of the deacylation tetrahedral intermediates of these enzymes. These compounds are micromolar inhibitors of class C β-lactamases but, very unexpectedly, not inhibitors of class A β-lactamases. We rationalize the latter result on the basis of a new mechanism of boronic acid inhibition of the class A enzymes. A stable inhibitory complex is not accessible because of the instability of an intermediate on its pathway of formation. The new boronic acids also do not inhibit bacterial DD-peptidases (penicillin-binding proteins). This result strongly supports a central feature of a previously proposed mechanism of action of β-lactam antibiotics, where deacylation of β-lactam-derived acyl-enzymes is not possible because of unfavorable steric interactions.

  14. A numerical analysis of a deep Mediterranean lee cyclone: sensitivity to mesoscale potential vorticity anomalies

    Science.gov (United States)

    Horvath, K.; Ivančan-Picek, B.

    2009-03-01

    A 12-15 November 2004 cyclone on the lee side of the Atlas Mountains and the related occurrence of severe bora along the eastern Adriatic coast are numerically analyzed using the MM5 mesoscale model. Motivated by the fact that sub-synoptic scales are more sensitive to initialization errors and dominate forecast error growth, this study is designed in order to assess the sensitivity of the mesoscale forecast to the intensity of mesoscale potential vorticity (PV) anomalies. Five sensitivity simulations are performed after subtracting the selected anomalies from the initial conditions, allowing for the analysis of the cyclone intensity and track, and additionally, the associated severe bora in the Adriatic. The results of the ensemble show that the cyclone is highly sensitive to the exact details of the upper-level dynamic forcing. The spread of cyclone intensities is the greatest in the mature phase of the cyclone lifecycle, due to different cyclone advection speeds towards the Mediterranean. However, the cyclone tracks diffluence appears to be the greatest during the cyclone movement out of the Atlas lee, prior to the mature stage of cyclone development, most likely due to the predominant upper-level steering control and its influence on the thermal anomaly creation in the mountain lee. Furthermore, it is quantitatively shown that the southern Adriatic bora is more sensitive to cyclone presence in the Mediterranean then bora in the northern Adriatic, due to unequal influence of the cyclone on the cross-mountain pressure gradient formation. The orographically induced pressure perturbation is strongly correlated with bora in the northern and to a lesser extent in the southern Adriatic, implying the existence of additional controlling mechanisms to bora in the southern part of the basin. In addition, it is shown that the bora intensity in the southern Adriatic is highly sensitive to the precise sub-synoptic pressure distribution in the cyclone itself, indicating a

    Full Text Available Hončova Hůrka hill in Skotnice near Příbor is important mineralogical locality. It is formed by rocks of the te­schenite association. It was opened as relatively small picrite quarry with further enlargement due to gravel mi­ning up to present status. Quarries in general possess wide range of habitats. Moreover, teschenite rock association with its high calcium content is favourable environment for land snails. Altogether, 27 land snail species were found in Hončova Hůrka hill, of which four are concerned as near threatened (Ena montana, Vertigo pygmaea, Daudebardia rufa and Pupilla muscorum. This site thus has a potential as local refugium for endangered species and deserves our attention.

  7. Modulation of the spectroscopic property of Bodipy derivates through tuning the molecular configuration.

    A series of six Bodipy derivatives, namely 4,4-difluoro-8-(4-amidophenyl)-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene (1), 4,4-difluoro-8-(4-methylphenyl)-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene (2), 4,4-difluoro-8-(4-nitrylphenyl)-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene (3), 4,4-difluoro-8-(4-amidophenyl)-3,5-dimethyl-4-bora-3a,4a-diaza-s-indacene (4), 4,4-difluoro-8-(4-methylphenyl)-3,5-dimethyl-4-bora-3a,4a-diaza-s-indacene (5), and 4,4-difluoro-8-(4-nitrylphenyl)-3,5-dimethyl-4-bora-3a,4a-diaza-s-indacene (6) were structurally characterized by single crystal X-ray diffraction analysis. Two methyl substituents attached at C-1 and C-7 positions of boron-dipyrromethene (Bodipy) moiety in compounds 1-3 were revealed to prevent the free rotation of the benzene moiety, resulting in a molecular configuration with an almost orthogonal dihedral angle between the Bodipy and benzene moieties with the dihedral angle in the range of 81.14-88.56°. This is obviously different from that for 4-6 with a free-rotating benzene moiety relative to the Bodipy core due to the lack of two methyl substituents in the latter series of compounds, leading to an enhanced interaction between the Bodipy and benzene moieties for 4-6 in comparison with 1-3. The resulting larger HOMO-LUMO gap for 1-3 than 4-6 results in a blue-shifted absorption band for 1-3 relative to that for 4-6. Comparative studies over their fluorescence properties also disclose the blue-shifted fluorescence emission band and corresponding higher fluorescence quantum yield for 1-3 relative to those of 4-6, revealing the effect of molecular configuration on the spectroscopic properties of Bodipy derivatives. Comparison of the redox behaviors of these two series of Bodipy compounds provides additional support for this point. In addition, the electron-donating/withdrawing property of the para substituent of the benzene moiety was shown to exhibit a slight influence on the electronic absorption and

    Ceraesignum maximum (G.B. Sowerby I, 1825), formerly Dendropoma maximum, was subject to a sudden, massive die-off in the Society Islands, French Polynesia, in 2015. On Mo'orea, where we have detailed documentation of the die-off, these gastropods were previously found in densities up to 165 m-2. In July 2015, we surveyed shallow back reefs of Mo'orea before, during and after the die-off, documenting their swift decline. All censused populations incurred 100% mortality. Additional surveys and observations from Mo'orea, Tahiti, Bora Bora, and Huahine (but not Taha'a) suggested a similar, and approximately simultaneous, die-off. The cause(s) of this cataclysmic mass mortality are currently unknown. Given the previously documented negative effects of C. maximum on corals, we expect the die-off will have cascading effects on the reef community.

    2003-01-01

    This paper describes the reconfigurable read-out system for the 82944 RICH-1 channels of the COMPASS experiment (NA58) at CERN. The system is based on 192 identical large front-end boards (BORA board). BORA was designed for acquiring, digitizing, threshold subtracting and transmitting event data. The overall operation of the board is controlled and supervised by a DSP tightly interacting with an FPGA that acts as a parallel co-processor. The DSP allows characterizing each analog channel by locally calculating noise and pedestal. Each BORA communicates with the outside world through two optical fibers and through a dedicated DSP network. One optical fiber is used to receive event triggers, and the other one is used to transmit event data to subsequent processing stages of the acquisition system. The DSP network allows reconfiguring and reprogramming the DSPs and FPGAs as well as acquiring sample events to visualize the overall operation of the system. The whole RICH has eight DSP networks working in parallel. ...

Salah satu kelebihan teknologi bahan bakar bola adalah menawarkan terobosan teknologi pengisian bahan bakar tanpa harus menghentikan produksi listrik. Selain itu, partikel bahan bakar pebble dengan kernel uranium oksida (UO2 atau uranium oksikarbida (UCO yang dibalut TRISO dan pelapisan silikon karbida (SiC dianggap sebagai opsi utama dengan pertimbangan performa tinggi pada burn-up bahan bakar dan temperatur tinggi. Makalah ini mendiskusikan pemodelan dan perhitungan transport Monte Carlo dalam teras HTR pebble bed. HTR pebble bed adalah reaktor berpendingin gas temperatur tinggi dan bermoderator grafit dengan kemampuan kogenerasi. Perhitungan dikerjakan dengan program MCNP5 pada temperatur 1200 K. Pustaka data nuklir energi kontinu ENDF/B-V dan ENDF/B-VI dimanfaatkan untuk melengkapi analisis. Hasil perhitungan secara keseluruhan menunjukkan konsistensi dengan nilai keff yang hampir sama untuk pustaka data nuklir yang digunakan. Pustaka ENDF/B-VI (66c selalu memproduksi keff lebih besar dibandingkan ENDF/B-V (50c maupun ENDF/B-VI (60c dengan bias kurang dari 0,25%. Kisi BCC memprediksi keff hampir selalu lebih kecil daripada kisi lainnya, khususnya FCC. Nilai keff kisi BCC lebih dekat dengan kisi FCC dengan bias kurang dari 0,19% sedangkan dengan kisi SH bias perhitungannya kurang dari 0,22%. Fraksi packing yang sedikit berbeda (BCC= 61%, SH= 60,459% tidak membuat bias perhitungan menjadi berbeda jauh. Estimasi keff ketiga model kisi menyimpulkan bahwa model BCC lebih bisa diadopsi dalam perhitungan HTR pebble bed dibandingkan model FCC dan SH.

    The main objective of the PhD project has been to develop concepts and methods that can be used to define, illustrate, analyse, and improve safety barriers in the operational phase of offshore oil and gas production platforms. The main contributions of this thesis are; Clarification of the term safety barrier with respect to definitions, classification, and relevant attributes for analysis of barrier performance Development and discussion of a representative set of hydrocarbon release scenarios Development and testing of a new method, BORA-Release, for qualitative and quantitative risk analysis of hydrocarbon releases Safety barriers are defined as physical and/or non-physical means planned to prevent, control, or mitigate undesired events or accidents. The means may range from a single technical unit or human actions, to a complex socio-technical system. It is useful to distinguish between barrier functions and barrier systems. Barrier functions describe the purpose of safety barriers or what the safety barriers shall do in order to prevent, control, or mitigate undesired events or accidents. Barrier systems describe how a barrier function is realized or executed. If the barrier system is functioning, the barrier function is performed. If a barrier function is performed successfully, it should have a direct and significant effect on the occurrence and/or consequences of an undesired event or accident. It is recommended to address the following attributes to characterize the performance of safety barriers; a) functionality/effectiveness, b) reliability/ availability, c) response time, d) robustness, and e) triggering event or condition. For some types of barriers, not all the attributes are relevant or necessary in order to describe the barrier performance. The presented hydrocarbon release scenarios include initiating events, barrier functions introduced to prevent hydrocarbon releases, and barrier systems realizing the barrier functions.

    Search games for a mobile or immobile hider traditionally have the hider permanently confined to a compact ‘search region’ making eventual capture inevitable. Hence the payoff can be taken as time until capture. However in many real life search problems it is possible for the hider to escape an area in which he was known to be located (e.g. Bin Laden from Tora Bora) or for a prey animal to escape a predator’s hunting territory. We model and solve such continuous time problems with escape wher...

U metalurškoj praksi već se dulji niz godina primjenjuju spektrometrijske metode analize i to najčešće optička emisijska spektrometrija s izravnim očitanjem. Međutim koncentracija pojedinih legirnih elemenata u suvremenim metalnim materijalima vrlo je niska, često niža od granice detekcije optičkih emisijskih spektrometara s izravnim očitanjem. U ovom radu određivana je koncentracija bora u nodularnom lijevu primjenom optičke emisijske spektrometrije s izravnim očitanjem (OES, optičke emisijske spektrometrije s induktivno spregnutom plazmom (ICP-OES te atomske apsorpcijske spektrometrije s grafitnom tehnikom (AAS-GF.

    Full Text Available Autobiography is a personal literary genre. There are not only real facts from the life of an individual, but also fantasy. This paper analyses the existence of aesthetics, historic, autobiographical and publishing style at the novel “One night and two daysprings” and “Interview with himself ” from Petro Marko. The aim of this paper is to point out the similarities of these two works in several areas and to show the talent of Petro Marko in using autobiographical data that show his creative consciousness. He uses several elements like: narrative, the game with calendar time, etc., to create the link between real and imaginary facts. His novel bears conflicts, political issues, social and vital such as fascism and anti-fascist forces, imprisonment, poverty etc. “One night and two daysprings”/”Night of Ustika”, proved these facts not only for Albanians but for all peoples of Europe and the world. His realistic characters embody certain social psychology and characteristics of Albanian mentality.

  16. Spatial separation of Plk1 phosphorylation and activity

    Directory of Open Access Journals (Sweden)

    Full Text Available Polo-like kinase 1 (Plk1 is one of the major kinases controlling mitosis and cell division. Plk1 is first recruited to the centrosome in S phase, then appears on the kinetochores in late G2 and at the end of mitosis it translocates to the central spindle. Activation of Plk1 requires phosphorylation of T210 by Aurora A, an event that critically depends on the co-factor Bora. However, conflicting reports exist as to where Plk1 is first activated. Phosphorylation of T210 is first observed at the centrosomes, but kinase activity seems to be restricted to the nucleus in the earlier phases of G2. Here we demonstrate that Plk1 activity manifests itself first in the nucleus using a nuclear FRET-based biosensor for Plk1 activity. However, we find that Bora is restricted to the cytoplasm and that Plk1 is phosphorylated on T210 at the centrosomes. Our data demonstrate that while Plk1 activation occurs on centrosomes, downstream target phosphorylation by Plk1 first occurs in the nucleus. We discuss several explanations for this surprising separation of activation and function.

  17. Polo-like kinase-1 controls Aurora A destruction by activating APC/C-Cdh1.

    Renske van Leuken

    Full Text Available Polo-like kinase-1 (Plk1 is activated before mitosis by Aurora A and its cofactor Bora. In mitosis, Bora is degraded in a manner dependent on Plk1 kinase activity and the E3 ubiquitin ligase SCF-betaTrCP. Here, we show that Plk1 is also required for the timely destruction of its activator Aurora A in late anaphase. It has been shown that Aurora A destruction is controlled by the auxiliary subunit Cdh1 of the Anaphase-Promoting Complex/Cyclosome (APC/C. Remarkably, we found that Plk1-depletion prevented the efficient dephosphorylation of Cdh1 during mitotic exit. Plk1 mediated its effect on Cdh1, at least in part, through direct phosphorylation of the human phosphatase Cdc14A, controlling the phosphorylation state of Cdh1. We conclude that Plk1 facilitates efficient Aurora A degradation through APC/C-Cdh1 activation after mitosis, with a potential role for hCdc14A.

  1. Assessment of current effect on waves in a semi-enclosed basin

    2012-04-01

    The wave-current interaction process in the semi-enclosed Adriatic Sea is studied using the Coupled Ocean-Atmosphere-Wave-Sediment Transport (COAWST) modeling system, which is used to exchange data fields between the ocean model ROMS (Regional Ocean Modeling System) and the wave model SWAN (Simulating WAves Nearshore). The 2-way data transfer between circulation and wave models is synchronous with ROMS providing current fields, free surface elevation, and bathymetry to SWAN. In particular, the 3-D current profiles are averaged using a formulation that integrates the near-surface velocity over a depth controlled by the spectral mean wave number. This coupling procedure is carried out up to coastal areas by means of an offline grid nesting. The parent grid covers the whole Adriatic Sea and has a horizontal resolution of 2.0 km, whereas the child grid resolution increases to 0.5 km but it is limited to the northern Adriatic Sea (Gulf of Venice), where the current effect on waves is investigated. The most frequent winds blowing on the Adriatic Sea are the so-called Bora and Sirocco which cause high waves in the Adriatic Sea, although Bora waves are generally fetch-limited. In fact, Bora winds blow orthogonal to the main basin axis (approximately aligned with the NW-SE direction), while Sirocco has large spatial scale being a southeasterly wind. For the numerical simulations, the meteorological forcings are provided by the operational meteorological model COSMO-I7, which is the Italian version of the COSMO Model, a mesoscale model developed in the framework of the COSMO Consortium. During the analysis period, the simulated wind, current and wave are compared with observations at the ISMAR oceanographic tower located off the Venice littoral. Wave heights and sea surface winds are also compared with satellite-derived data. To account for the variability of sea states during a storm, the expected maximum individual wave height in a sea storm with a given history is also

    Located between the Trnovski gozd (1500 m a.s.l.) barrier and Karst (500 m a.s.l.) plateau, Vipava valley (100 m a.s.l.) is a natural laboratory for studies of strong, gusty North-East Bora winds. Being just 30 km away from the coastal line, the weather in the valley is affected by both the sub-mediterranean and sub-alpine climate, leading to abrupt weather changes within the valley. Due to its orography, there are only three prevailing wind directions (North-East, South-East and South-West), which were found to give rise to specific types of atmospheric structures, presented in this contribution. Atmospheric properties were measured at the floor of the Vipava valley, using twelve ultrasonic anemometers, two GPS ionospheric monitors, two meteorological stations and an infra-red Mie-scattering lidar operating at 1064 nm at Ajdovščina. These devices yielded continuous data on wind speed and direction, average absolute humidity within the valley, relative humidity, pressure and temperature. Lidar provided high temporal and spatial resolution backscatter data on aerosols, which were used as tracers for atmospheric flows. Selected time periods in 2015, when lidar data was available, were classified according to wind speed and direction in the valley and investigated in detail, in particular in term of appearance of atmospheric structures. In periods with low wind speeds (predominantly from South-West), vertical evolution of the planetary boundary layer (PBL) was found to be governed by solar radiation and clouds. In such conditions typical daily variations in PBL height with vertical mixing due to convection were observed. Periods with strong or moderate wind mainly correspond to Bora. Due to the airflow over the Trnovski gozd barrier in Bora cases, convection within the PBL was found to be much weaker due to strong turbulence close to the ground, which inhibited the mixing through the entire PBL. Above the PBL, gravity waves were observed. Periods with moderate South

    Over the past 4 years, the African Health Profession Regulatory Collaborative for nurses and midwives has supported 12 countries establish national continuing and professional development frameworks and programs, linking continuing education to nursing and midwifery re-licensure through technical assistance and improvement grants. However, lack of electronic media and rural practice sites, differences in priority content, and varying legal frameworks make providing accessible, certifiable, and up-to-date online continuing education content for the more than 300,000 nurses and midwives in the 17 member countries of the East, Central, and Southern Africa College of Nursing a major challenge. We report here on how the East, Central, and Southern Africa College of Nursing, with technical assistance from an Afya Bora Fellow, developed an online continuing professional development library hosted on their Web site using data collected in a survey of nursing and midwifery leaders in the region.

    Nucleophilic substitution on 3-bromo/3,5-dibromo-4,4'-difluoro-8-(aryl)-4-bora-3a,4a-diaza-sindacene (BODIPY), substituted with anisyl or thienyl at meso positions, with neat pyrrole afforded the mono and di-pyrrole substituted BODIPYs 1–4 in good yields. Large bathochromic shifts, upto ∼180 nm in absorption maxima (581–682 nm), and fluorescence maxima (606–695 nm) were observed for these BODIPYs. Absorption and fluorescence properties were studied in different solvents to compare the effect of mono and di substitution on BODIPY. The Lippert-Mataga equations were used which predict strong polarization of monosubstituted BODIPYs. Electrochemical studies were carried out to find the oxidation potential and HOMO energy levels were calculated. Theoretical studies of 1–4 provide the insight on the electron density distribution in 1–4. Theoretical and experimental photo-physical studies in different solvents were correlated to findthe substituent effects on BODIPY.

    Full Text Available Numerical simulations of the winter circulation in and around the Gulf of Trieste are presented. The model, based on the architecture of the Princeton Ocean Model, gave reasonable results for circulation in the Gulf during the winter period, when the dominant bora wind is blowing. Three model runs with different initial and surface boundary conditions show that there is an outflow along the shallow northern coastline of the Gulf and over the surface of the major part of the area, and an inflow at depth in the central and southern parts of the Gulf. However, the variability of the temperature and salinity fields when vertical fluxes of heat and salinity are present cause a weak outflow in an area near the southern part of the Gulf, and make the general circulation pattern more complex.

    The paper describes formation and spreading of dense shelf waters in the Adriatic Sea (North Adriatic Dense Water, NAdDW) during the winter of 2012 as a consequence of an intense and long cold air outbreak of northeasterly Bora winds. As a result, during February 2012 northern Adriatic Sea water temperature dropped to about 6 °C and density exceeded 1030 kg/m3, most likely the maximum value since 1929. NAdDW dynamics has been investigated by means of a 3-D ocean-wave coupled model running on a high resolution and eddy-permitting grid. The numerical experiments have relied on the Coupled-Ocean-Atmosphere-Wave-Sediment-Transport (COAWST) system forced one-way with atmospheric forcings provided by the model COSMO-I7. A suite of observational data has been used to characterize the Bora event and evaluate numerical model performance. At sub-basin scales, the newly formed waters flowing southerly have produced a water renewal of the northern Adriatic, as more than 50% of water volumes have left the basin. Dense waters volume transports, evaluated through different Adriatic cross-sections, have been modulated by tides (damped for the densest water masses) and reached about 1 Sv. The contribution of wave-induced forcings has been quantified and examined, indicating that these represent a major driving mechanism during NAdDW production and spreading phases. This work provides evidence that NAdDW is spread accordingly with two different mechanisms: at early stages of its formation, the wind-driven ocean circulation pushes newly formed waters to leave the northern basin with relatively high speeds (about 0.30 m/s). Later on, remaining NAdDW leaks slowly out (0.09 m/s as average) from the production site. Residence times of dense waters in the north, middle, and south Adriatic Sea are also documented.

    The design, synthesis, photochemical properties, and biological evaluation of a novel photoactivatable bichromophoric conjugate are reported. The compound 1, [4-(4,4-difluoro-2,6-diiodo-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacen-8-yl)-N-(3-((4-nitro-3-(trifluoromethyl)phenyl)amino)propyl)butanamide] combines a 2,6-diiodo-1,3,5,7-tetramethyl BODIPY derivative as singlet oxygen ((1) O2 ) photosensitizer and 4-nitro-3-(trifluoromethyl)aniline (NOPD) as nitric oxide (NO) photodonor, joined by an alkyl spacer. These two chromogenic units absorb in distinct regions of the visible spectrum, and their individual photochemical properties are conserved in the molecular conjugate. Irradiation of the bichromophoric conjugate with green light afforded (1) O2 in high quantum yields, whereas (1) O2 production was negligible with the use of blue light; under this latter condition, NO was released. Photogeneration of NO and cytotoxic (1) O2 can therefore be regulated by appropriately tuning the excitation light wavelength and intensity. Tested on melanoma cancer cells, this resulted in amplified photomortality relative to that of a structurally correlated model compound 2 [4-(4,4-difluoro-2,6-diiodo-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacen-8-yl)-N-(3-(p-tolylamino)propyl)butanamide] deprived of the NO-release capacity. The cellular uptake of 1, evaluated by confocal fluorescence microscopy, showed that the product is localized in the cytoplasm.

    Two new boron-dipyrromethenes decorated with 8-hydroxyquinoline-naphthoate moiety, namely 4,4-difluoro-8-(5-(8-hydroxyquinoline-naphthoate))-3,5-dimethyl-4-bora-3a,4a-diaza-s-indacene (8-HQ-N-DMe-Bodipy) (1) and 4,4-difluoro-8-(5-(8-hydroxyquinoline-naphthoate))-1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene (8-HQ-N-TMe-Bodipy) (2) have been synthesized. Single crystal X-ray diffraction analysis discloses the very much similar steric arrangement of 8-hydroxyquinoline-naphthoate moiety in these two compounds as revealed by the close torsion angle of C-C-O-C bridge, 174.15 and 171.81° for 1 and 2, respectively, despite the different dihedral angle between quinoline moiety and Bodipy fluorophore for 1 (73.46°) and 2 (82.26°) due to the steric hindrance originated from the C-1/C-7 methyl substituents on Bodipy core for the latter species. Systemic optical studies unravel the red-shifted absorption and fluorescence emission together with slightly lower quantum yield for 1 relative to that of 2, indicating the configuration effect on their spectroscopic properties. However, the binding of Cu(2+) with hydroxyquinoline-naphthoate receptor in both 1 and 2 leads to similar fluorescent quenching characteristic due to the photo-induced electron transfer process on the basis of density functional theory calculations, suggesting their high sensitively fluorescent ON-OFF sensing potential to Cu(2+) almost unaffected by molecular configuration.

    Shelf dense water formation (DWF) events may be taking place during winter time on the broad, shallow shelf in the northern region of the Adriatic basin exposed to the Bora winds, bringing cold, dry air from the north-east down the Dinaric Alps. Indeed, the resulting intense evaporation and cooling of the shelf waters may produce North Adriatic Dense Water (NAdDW), which then tends to sink and ''cascade'' all the way to the southern basin. During these rather episodic formation processes, more frequent during winter time, the main controlling factors are intense cold wind out- breaks, the ambient water density, preconditioned during late autumn, and also other factors, e.g. river discharges. When such processes of buoyancy extraction happen, several isopycnic surfaces outcrop and very often the whole water column (20-25 m deep) may be ventilated. However, the general process of northern water masses flowing to the southern part of the Adriatic basin is complex and far from being completely understood. In order to understand and model these processes, it is mandatory to utilize high resolution meteorological forcing fields and circulation models, at least to model particular events in Adriatic marine circulation, if not its longer term (e.g., seasonal) characteristics. The use of low resolution winds in fact necessarily implies a calibration factor to better match surface fluxes and to reproduce wind-driven circulation. This is particularly evident in the case of the cross-basin Bora pattern, because the complexity and small scale of Adriatic orography is often poorly reproduced in atmospheric models, while Bora flow is composed of an alternation of high and low wind speed 'strips' crossing the Adriatic in correspondence of the fine scale (10-100 km) Balkanic orographic gaps. Within the framework of activities of the Italian flagship Project "RITMARE" and of the FIRB "DECALOGO", we focused on the current meteorological modeling capabilities to describe an event of

    Full Text Available A new sediment transport model, considering currents, tides and waves is presented for the Adriatic Sea basin. The simulations concentrate on the winter of 2002–2003 because of field data availability and interesting intermittent processes occurrence. A process oriented analysis is performed to investigate the impact that Sirocco and Bora wind regimes have on sediment transport. The comparisons of the simulations with the observed data show that the model is capable to capture the main dynamics of sediment transport along the Italian coasts and the sediment concentration within the water column. This latter can reach values up to several g L−1, especially within the first centimetres above the bottom. The sediments are transported mainly southwards along the Italian coasts, consistently with the known literature results, except during Sirocco wind events, which can be responsible for reversing the coastal circulation in the northern area of the basin, and consequently the sediment transport. The resuspension of sediments is also related to the specific wave regimes induced by Bora and Sirocco, the former inducing resuspension events near the coasts while the latter causing a more diffused resuspension regime in the Northern Adriatic basin. Beside the realistic representation of short timescales resuspension/deposition events due to storms, the model was also used to investigate persistent erosion or deposition areas in the Adriatic Sea. Two main depocenters were identified: one, very pronounced, in the surroundings of the Po river delta, and another one a few kilometres off the coast in front of the Ancona promontory. A third region of accumulation, even if less intense, was found to be offshore the southernmost limit of the Gargano region. On the contrary the whole western coast within a distance of a few kilometres from the shore was found to be subject to prevailing erosion. The comparison with observed accumulation and erosion data shows

    Recent studies of sediment dynamics and clinoform development in the northern Adriatic Sea focused on winter 2002-2003 and provided the data and motivation for development of a detailed sediment-transport model for the area near the Po River delta. We used both idealized test cases and more realistic simulations to improve our understanding of seasonal sediment dynamics there. We also investigated the relationship between physical processes and the observed depositional products; e.g. the accumulation of sediment very near the Po River distributary mouths. Sediment transport near the Po River was evaluated using a three-dimensional ocean model coupled to sediment-transport calculations that included wave- and current-induced resuspension, suspended-sediment transport, multiple grain classes, and fluvial input from the Po River. High-resolution estimates from available meteorological and wave models were used to specify wind, wave, and meteorological forcing. Model results indicated that more than half of the discharged sediment remained within 15??km of the Po River distributary mouths, even after two months of intensive reworking by winter storms. During floods of the Po River, transport in the middle to upper water column dominated sediment fluxes. Otherwise, sediment fluxes from the subaqueous portion of the delta were confined to the bottom few meters of the water column, and correlated with increases in current speed and wave energy. Spatial and temporal variation in wind velocities determined depositional patterns and the directions of sediment transport. Northeasterly Bora winds produced relatively more eastward transport, while southwesterly Sirocco winds generated fluxes towards both the north and the south. Eastward transport accounted for the majority of the sediment exported from the subaqueous delta, most likely due to the frequent occurrence of Bora conditions. Progradation of the Po River delta into the Adriatic Sea may restrict the formation of the

    In the Guadeloupe and Saint Martin islands, Aedes aegypti mosquitoes are the only recognized vectors of dengue, chikungunya, and Zika viruses. For around 40 years, malathion was used as a mosquito adulticide and temephos as a larvicide. Since the European Union banned the use of these two insecticide molecules in the first decade of the 21st century, deltamethrin and Bacillus thuringiensis var. israelensis are the remaining adulticide and larvicide, respectively, used in Guadeloupe. In order to improve the management of vector control activities in Guadeloupe and Saint Martin, we investigated Ae. aegypti resistance to and mechanisms associated with deltamethrin, malathion, and temephos. Ae. aegypti mosquitoes were collected from six different localities of Guadeloupe and Saint Martin. Larvae were used for malathion and temephos bioassays, and adult mosquitoes for deltamethrin bioassays, following World Health Organization recommendations. Knockdown resistance (Kdr) genotyping for V1016I and F1534C mutations, and expression levels of eight enzymes involved in detoxification mechanisms were examined in comparison with the susceptible reference Bora Bora strain. Resistance ratios (RR50) calculated for Ae. aegypti larvae showed high resistance levels to temephos (from 8.9 to 33.1-fold) and low resistance levels to malathion (from 1.7 to 4.4-fold). Adult females displayed moderate resistance levels to deltamethrin regarding the time necessary to affect 50% of individuals, varying from 8.0 to 28.1-fold. Molecular investigations on adult mosquitoes showed high resistant allele frequencies for V1016I and F1534C (from 85 to 96% and from 90 to 98%, respectively), as well as an overexpression of the glutathione S-transferase gene, GSTe2, the carboxylesterase CCEae3a, and the cytochrome genes 014614, CYP6BB2, CYP6M11, and CYP9J23. Ae. aegypti populations from Guadeloupe and Saint Martin exhibit multiple resistance to organophosphates (temephos and malathion), and pyrethroids

    This study aims to document the effects of imposing different river runoff forcing and tidal forcing to the dense water formation (DWF) rates and dynamics in a semi-enclosed sea. An extreme DWF episode that occurred in the winter of 2012 in the shallow northern Adriatic Sea during a prolonged cold bora wind outbreak event has been reproduced using a one-way coupled atmosphere-ocean modelling system comprised of the atmospheric Aladin/HR mesoscale model and ocean ROMS model. Three different river runoff forcing and tides/no tides scenarios were imposed on the model. The introduction of tides and river climatology instead of real rivers did not substantially change the modelled DWF transports and volumes, whereas the simulation using the old Raicich climatology resulted in a substantial freshening of the entire Adriatic that reduced or prevented the DWF at sites in the northern and northeastern Adriatic. The necessity of using an up-to-date river runoff climatology to properly reproduce the DWF in semi-enclosed seas is emphasised.

    Full Text Available ABSTRACT: Lippia rotundifolia is a specie native to the Brazilian Cerrado, endemic to the Cadeia do Espinhaço mountain range. Due to the limited information about the species, the present study aimed to characterize the ecogeography, climate conditions and physical and chemical characteristics of the soil of Lippia rotundifolia in the state of Minas Gerais, Brazil. Thirteen sites were ecogeographically characterized: Parque Estadual Veredas do Peruaçu; Gigante; Rio do Peixe; AEP of Olhos D’água; Joaquim Felício; Parque Estadual do Rio Preto; São Gonçalo do Rio das Pedras; Rio Tigre; RPPN Brumas do Espinhaço; Lapinha; Poço Bonito; Abóboras; and Parque Estadual de Serra Nova. Environments belonged to Cerrado and Caatinga biomes, specifically in rocky and altitude fields. The species occurs at altitudes between 691-1311m, with precipitation between 700 to 1600mm and average temperature between 14.5 to 24°C. In these vegetation types, the soils were sandy, hyper dystrophic and highly toxic with a low cation exchange capacity. These characteristics make the species undemanding with regard to edaphoclimatic and ecogeographic factors.

    Full Text Available Carla Vaz Ferreira, Débora Rodrigues Siqueira, Lucieli Ceolin, Ana Luiza MaiaThyroid Section, Endocrine Division, Hospital de Clínicas de Porto Alegre, Porto Alegre, BrazilAbstract: Medullary thyroid carcinoma (MTC is a rare malignant tumor originating from thyroid parafollicular C cells. This tumor accounts for 3%–4% of thyroid gland neoplasias. MTC may occur sporadically or be inherited. Hereditary MTC appears as part of the multiple endocrine neoplasia syndrome type 2A or 2B, or familial medullary thyroid cancer. Germ-line mutations of the RET proto-oncogene cause hereditary forms of cancer, whereas somatic mutations can be present in sporadic forms of the disease. The RET gene encodes a receptor tyrosine kinase involved in the activation of intracellular signaling pathways leading to proliferation, growth, differentiation, migration, and survival. Nowadays, early diagnosis of MTC followed by total thyroidectomy offers the only possibility of cure. Based on the knowledge of the pathogenic mechanisms of MTC, new drugs have been developed in an attempt to control metastatic disease. Of these, small-molecule tyrosine kinase inhibitors represent one of the most promising agents for MTC treatment, and clinical trials have shown encouraging results. Hopefully, the cumulative knowledge about the targets of action of these drugs and about the tyrosine kinase inhibitor-associated side effects will help in choosing the best therapeutic approach to enhance their benefits.Keywords: medullary thyroid carcinoma, proto-oncogene RET, tyrosine kinase inhibitors

    Full Text Available A case of snow fall in the plains of the Northern Italian region Veneto is presented from a forecasters' perspective. Contrasting forecast guidance came from the ECMWF global model and the limited area model LAMI. The former showed a marked warm-moist Sirocco flow coming from the Adriatic Sea onto the coast at all levels, the latter discerned a distinct cold air flow from the north-east along the foothills of the Alps. The integrated observing network of the Centro Meteorologico di Teolo ARPA Veneto revealed this cold-air structure and helped the forecaster in the choice of the forecast and underpin the snowfall alert to the road authorities. It is argued that this feature is a crucial element for the occurrence of snowfall over the Veneto plains, and that the high-resolution numerical weather prediction model was essential in describing this mesoscale feature. The nature of the north-easterly flow is thought to be a combination of a Bora like flow and a barrier jet induced by flow blocking by the Alps.

    Full Text Available This paper presents some morphosyntactic features of Ocaina, a seriously endangered, underdescribed language of the Colombian-Peruvian Amazon region. Ocaina has an extensive nominal classification system and number markers—dual  and plural—suffixed to both nouns and person markers on verbs. Grammatical relations follow a nominative-accusative pattern and are coded by a relatively rigid constituent order SOV (Subject-Object-Verb; by verbal prefixes (o-s-V and enclitics (o-V=s, with just one prefix for objects of monotransitive and ditransitive verbs; and by the marking of oblique objects of certain verbs by case suffixes and postpositions. Most of the Ocaina features described are shared with Uitoto of the Witotoan family; many are also shared with Bora (Boran family, whose genetic link to the Witotoan family is still hypothetical. All these languages share certain features with neighboring languages, such as those of the Vaupés region, e.g. nominal classification and nominative-accusative alignment. We suggest that some aspects of Ocaina morphosyntax are probably inherited from the Witotoan family while others are better explained by areal diffusion.

Yet, the evaluation of electronic learning services is intrinsically linked to improving the performance of documentation services. In this paper, I describe my perspectives on the design, use and evaluation of an electronic learning platform using a lens of a practitioner from a third world country. I further delineate the challenges and constraints I encountered as a student learning about e-learning platforms and using e-learning platform services at an institution of higher learning in Sweden. In particular, the Ping Pong system at the University of Boras, Sweden, and the electronic print in the Library and Information Science (E-LIS, one of the services from the bulletin board for libraries (BUBL Link information gateway, will be evaluated. It is anticipated that this experiential evaluation will provide designers of e-learning platforms with insights and strategies for refining the e-learning platform to facilitate teaching activities and promote students’ learning efficiency and satisfaction.

    In recent years, wave reanalyses have become popular as a powerful source of information for wave climate research and engineering applications. These wave reanalyses provide continuous time series of offshore wave parameters; nevertheless, in coastal areas or shallow water, waves are poorly described because spatial resolution is not detailed. By means of wave downscaling, it is possible to increase spatial resolution in high temporal coverage simulations, using forcing from wind and offshore wave databases. Meanwhile, the reanalysis wave databases are enough to describe the wave climate at the limit of simulations; wind reanalyses at an adequate spatial resolution to describe the wind structure near the coast are not frequently available. Remote sensing synthetic aperture radar (SAR) has the ability to detect sea surface signatures and estimate wind fields at high resolution (up to 300 m) and high frequency. In this work a wave downscaling is done on the northern Adriatic Sea, using a hybrid methodology and global wave and wind reanalysis as forcing. The wave fields produced were compared to wave fields produced with SAR winds that represent the two dominant wind regimes in the area: the bora (ENE direction) and sirocco (SE direction). Results show a good correlation between the waves forced with reanalysis wind and SAR wind. In addition, a validation of reanalysis is shown. This research demonstrates how Earth observation products, such as SAR wind fields, can be successfully up-taken into oceanographic modeling, producing similar downscaled wave fields when compared to waves forced with reanalysis wind.

    Large areas in South East Europe offer perfect conditions for the Utilisation of Wind Energy. Local wind systems like ''Bora'', which occurs along the Adriatic Sea, or ''Koshava'', which flows between the ridge of the Carpathian Mountains and the Balkan Mountains from Romania over to Serbia, are generated through differences in pressure and temperature between the adjacent regions. Those wind systems therefore can be described as 'home made' and have very individual characteristics. Despite the excellent wind conditions of those locations, the mainly cliffy and complex terrain and the extreme wind conditions with turbulences and strong gusts make great demands on the design and operation of the wind turbines. Exactly those problems the European Commission asked to be investigated and therefore defined 'Complex terrain and local wind systems' as one of the research topics in the last call of the 6th Framework Programme. Under the lead management of Verein Energiewerkstatt, a consortium of ten partners from seven middle- and southeast European countries took part in this call for proposals and received acceptance for the submitted Project ''SEEWIND - South-East European Wind Energy Exploitation''.

    Full Text Available The isolation of lipid-rich autochthonous strains of microalgae is a crucial stage for the development of a microalgae-based biofuel production plant, as these microalgae already have the necessary adaptations to withstand competition, predation and the temperatures observed at each production site. This is particularly important in extreme climates such as in Saudi Arabia. Resorting to fluorescence activated cell sorting (FACS we screened for and isolated several microalgal strains from samples collected from the Red Sea. Relying on the fluorescence of BODIPY 505/515 (4,4-difluoro-1,3,5,7-tetramethyl-4-bora-3a,4a-diazasindacene and growth performance, four promising candidates were identified and the total lipid content and fatty acid profile was assessed for biofuels production. Selected isolates were classified as chlorophytes, belonging to three different genera: Picochlorum, Nannochloris and Desmochloris. The lipid contents were assessed microscopically by means of BODIPY 505/515-associated fluorescence to detect intracellular lipid bodies, which revealed several lipid drops in all selected strains. This result was confirmed by lipid gravimetric determination, which demonstrated that all strains under study presented inner cell lipid contents ranging from 20% to 25% of the biomass dry weight. Furthermore, the fatty acid methyl esters profile of all strains seems ideal for biodiesel production due to a low degree of polyunsaturated fatty acid methyl esters and high amount of palmitic and oleic acids.

    The synthesis and single-molecule imaging of two inherently fluorescent nanocars equipped with adamantane wheels is reported. The nanocars were imaged using 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) as the chromophore, which was rigidly incorporated into the nanocar chassis via Sonogashira cross-coupling chemistry that permitted the synthesis of nanocars having different geometries. In particular, studied here were four- and three-wheeled nanocars with adamantane wheels. It was found that, for the four-wheeled nanocar, the percentage of moving nanocars and the diffusion constant show a significant improvement over p-carborane-wheeled nanocars with the same chassis. The three-wheeled nanocar showed only limited mobility due to its geometry. These results are consistent with a requisite wheel-like rolling motion. We furthermore developed a model that relates the percentage of moving nanocars in single-molecule experiments with the diffusion constant. The excellent agreement between the model and the new results presented here as well as previous single-molecule studies of fluorescent nanocars yields an improved understanding of motion in these molecular machines.

    Optical highlighters are photoactivatable fluorescent molecules that exhibit pronounced changes in their spectral properties in response to irradiation with light of a specific wavelength and intensity. Here, we present a novel design strategy for a new class of caged BODIPY (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene) fluorophores, based on the use of photoremovable protecting groups (PRPGs) with high reduction potentials that serve as both a photosensitive unit and a fluorescence quencher via photoinduced electron transfer (PeT). 2,6-Dinitrobenzyl (DNB)-caged BODIPY was efficiently photoactivated, with activation ratios exceeding 600-fold in aqueous solutions. We then combined this photoactivatable fluorophore with a SNAP (mutant of O(6)-alkylguanine DNA alkyltransferase) ligand to obtain a small-molecule-based optical highlighter for visualization of protein dynamics, using the well-established SNAP tag technology. As proof of concept, we demonstrate spatiotemporal imaging of the fusion protein of epidermal growth factor receptor (EGFR) with SNAP tag in living cells. We also demonstrate highlighting of cells of interest in live zebrafish embryos, using the fusion protein of histone 2A with SNAP tag.

    A Bodipy (4,4-difluoro-4-bora-3a,4a-diaza-s-indacene) derivative has been conceived and synthesized starting from l-aspartic acid, as a selective turn-off sensor of Cu(2+) ions. Its acid-base properties were determined to study the formation of metal/sensor complex species by titration of solutions each containing a different metal ion, such as Cu(2+), Ca(2+), Zn(2+), Pb(2+) and Hg(2+) and different metal/sensor ratios. The speciation models allowed us to simulate the distribution of the metal/sensor complex species at the normal concentrations of the corresponding metals present in biological fluids. The distribution diagrams, obtained by varying the concentration of sensor 1, clearly indicate that sensor 1 responds selectively to Cu(2+) at micromolar concentrations, even in the presence of other more abundant metal cations Ca(2+). Finally, we analyzed the cellular uptake of sensor 1 on human erythrocytes and its ability to chelate Cu(2+) in the cellular environment. Results indicate that it crosses the plasmatic membrane and colors the cells of a bright fluorescent red. Exposing the fluorescent cells to Cu(2+) results in a complete cellular photobleaching of the red fluorescence, indicating that sensor 1 is able to detect metal changes in the cytosolic environment.

    The generation of 1,2-azaborine (4), the BN-analogue of ortho-benzyne, was recently achieved by elimination of tert-butyldimethylchlorosilane under the conditions of flash vacuum pyrolysis. The present investigation identifies by computational means pathways for the thermal isomerization and fragmentation of 1,2-azaborine. The computations were performed using single reference (hybrid/density functional, second order Møller-Plesset perturbation, and coupled cluster theories) as well as multiconfiguration methods (complete active space SCF based second order perturbation theory, multireference configuration interaction, and multiconfiguration coupled electron pair approximation) with basis sets up to polarized triple-ζ quality. The 1,2-azaborine is, despite the distortion of its molecular structure, the most stable C4H4BN isomer investigated. The formation of BN-endiyne isomers is highly unfavorable as the identified pathways involve barriers close to 80 kcal mol(-1). The concerted fragmentation to ethyne and 2-aza-3-bora-butadiyne even has a barrier close to 120 kcal mol(-1). The fragmentation of BN-enediynes has energetic requirements similar to enediynes. © 2015 Wiley Periodicals, Inc.

Embora o crítico estado nutricional da população-alvo possa fazer qualquer questionamento técnico ou ético parecer por demais filosófico, uma série de considerações nutricionais, toxicológicas e até de viabilidade prática sugerem que a posição adotada pelo Inan deveria ser revista. A solução da multimistura, talvez válida para situações transitórias de extrema pobreza, carece de universalidade para ser utilizada, independentemente de faixa etária, estado nutricional e período de duração da intervenção.

    Highlights: • BODIPY was synthesized, and then attached to magnetic nanoparticles. • Ni(II) ions were chelated on prepared material. • The binding of cytochrome c to obtained material was studied. - Abstract: In this study, 3,5-{Bis[4,4-difluoro, 8-(2,6-diethyl, 1,3,5,7-tetramethyl-4-bora-3a,4a-diaza-s-indacene)]}benzoylchloride (BODIPY) was synthesized for the improving of a new immobilized metal affinity supporting material. Firstly, the synthesized BODIPY was immobilized on iron oxide superparamagnetic nanoparticles (SPIONs) and then, Ni(II) ions were chelated with the active terminals of BODIPY on nanoparticles surfaces to prepare an immobilized metal affinity (IMA) adsorbent for protein adsorption. The amount of BODIPY coated on SPIONs was about 29.7 μM at 10 mg nanoparticles. 738 μmol of Ni(II) ions were loaded to 10 mg of the SPIONs/BODIPY. The binding amount of cytochrome c was found to be 170 μg to the SPIONs/BODIPY/Ni at pH 7.4. The binding amount of the molecules on SPIONs was analyzed by using UV–vis, fluorescence and atomic absorption spectroscopy. The characterization of the prepared surfaces was performed by FT-IR, SEM and TEM.

    Review of the first comprehensive meta-analysis of VBM (voxel-based morphometry) studies in schizophrenia indicates asymmetrical reductions of anterior cingulate gyrus to the right, and medial temporal lobe (including the uncus) and para-hippocampal gyrus to the left. In subsequent meta-analyses of schizophrenia and bipolar disorder change in these limbic structures is systematically related to change in the insula. Deficits in insula (and para-hippocampal gyrus) to the left, and dorsal anterior cingulate gyrus to the right are greater in schizophrenic psychoses whereas deficits in anterior cingulate to the left and insula to the right are greater in bipolar illness. Thus (1) brain structures implicated in schizophrenia include those implicated in bipolar disorder, (2) the variation that separates the prototypical psychoses may be a subset of that relating to the structural asymmetry (the "torque") characteristic of the human brain, and (3) the meta-analysis of Bora et al. (2012) indicates that laterality of involvement of the insula and cingulate gyrus across the spectrum of bipolar and schizophrenic psychoses is critically dependent upon the sex ratio. Thus structural change underlying the continuum of psychosis relates to the interaction of laterality and sex.

    Full Text Available Among several alternative agricultural systems have been developed, organic agriculture has deserved increasing interest from. The objective of this paper was comparing both organic (OS and conventional (CS tomato cropping systems for varieties Débora and Santa Clara, through an interdisciplinary study. The experiment was set up in a randomized blocks design with six replicates, in a dystrophic Ultisol plots measuring 25 ´ 17 m. Cropping procedures followed by either local conventional or organic growers practices recommendations. Fertilization in the OS was done with organic compost, single superphosphate, dolomitic limes (5L, 60 g, and 60 g per pit, and sprayed twice a week with biofertilizer. Fertilization in the CS was done with 200 g 4-14-8 (NPK per pit and, after planting, 30 g N, 33 g K and 10.5 g P per pit; from 52 days after planting forth, plants were sprayed once a week with foliar fertilizer. In the CS, a blend of insecticides, fungicides and miticides was sprayed twice a week, after planting. In the OS, extracts of black pepper, garlic, and Eucalyptus; Bordeaux mixture, and biofertilizer, were applied twice a week to control diseases and pests. Tomato spotted wilt was the most important disease in the OS, resulting in smaller plant development, number of flower clusters and yield. In the CS, the disease was kept under control, and the population of thrips, the virus vector, occurred at lower levels than in the OS. Variety Santa Clara presented greater incidence of the viral disease, and for this reason had a poorer performance than 'Débora', especially in the OS. Occurrence of Liriomyza spp. was significantly smaller in the OS, possibly because of the greater frequency of Chrysoperla. The CS had smaller incidence of leaf spots caused by Septoria lycopersici and Xanthomonas vesicatoria. However, early blight and fruit rot caused by Alternaria solani occurred in larger numbers. No differences were observed with regard to the

As mercadorias são destinadas aos atacadistas, que podem também ser produtores rurais ou apenas intermediários. O tomate possui grande representatividade de comercialização dentro dessas centrais de abastecimento. A partir de questionários, identificou-se o perfil dos comerciantes de tomate de mesa na CEAGESP. Constatou-se que 45,8% dos entrevistados possuem um volume médio de tomate comercializado durante o ano maior que 10.000 toneladas, sendo que, desses, 70,8% possuem produção própria de tomate. As cultivares Carmen e Débora foram as líderes de comercialização no período avaliado. Os resultados apontaram que os atacadistas comercializam com mais de um tipo de comprador, sendo os principais feirantes e supermercados, com ampla utilização da embalagem de madeira, caixa K, seguindo com 20,8% em caixas plásticas e 16,7% com caixas de papelão.

    Full Text Available It is an important period as a nearly total breaking with the way the cartoon story is understood happens; this kind of publications will not be devoted any more to the leisure and the education of the children and the young readers. The echos of the authored comic slowly came to Spain, there are some shy national authors along with works published in France, Argentina and Italy which are translated. As it is considered as a narrative expression form and grapically complex, it also stimulates the research on this media through different publications and exhibitions or even through semiological studies made at the university. In the late franquismo some magazines, fascicles and books, are published and show that this media had become “adult”. In one hand there are some experiments done related to genres like fantasy, adventures or horror and in the other hand, the underground comic appears as a countercultural autoctonous experience. Magazines such as Totem, Blue Jeans or Bumerang fixed from 1977 the guidelines that marked the following revolution of the Spanish industry. The very first disembarkation, compact and real, of the comic for adults, happens in 1978 with the publishing of a comic called 1984, then some new magazines such as El Víbora, Cimoc or Cairo got published too. The evolution of the comic devoted to children and young people is studied too. Considered in a certain way as an industrial process, this ended in 1986 with the closing of the Bruguera Publishing House.

    Full Text Available Tomato plants are susceptible to bacterial wilting, which causes production losses varying from 10 to 100 %. A method for controlling this disease is the use of grafting on resistant rootstocks. This work had the objective of evaluating tomato genotypes for the resistance to Ralstonia solanacearum and the grafting technique as an alternative for the bacterial wilt control in the region of Recôncavo Baiano, Brazil. To evaluate the resistance to R. solanacearum, four local genotypes, collected in different regions of Bahia, the cv. Santa Clara as a susceptible treatment, and the Hawaii 7996 (H7996, as a resistant treatment were studied. For the evaluation of grafting method for control of bacterial wilt, the H7996 was used as rootstock, and the cvs. Santa Clara, Santa Cruz Kada, and Débora Plus were used as the scion plants. Both experiments were evaluated in an area infested with R. solanacearum, for a period of 65 days for the selection of the rootstocks and 45 days for the evaluation of the grafting method. Only the H7996 can be recommended as a R. solanacearum resistant rootstock. The other genotypes showed susceptibility to the pathogen. The grafting on the H7996 did not show incompatibility with the scion tomato cultivars tested and reached 100 % control of the bacterial wilt disease, for all treatments, suggesting that this method can be used as an alternative for the bacterial wilt control, allowing the production of susceptible tomato cultivars in areas infested with R. solanacearum A suscetibilidade do tomateiro à murcha bacteriana (Ralstonia solanacearum causa perdas que vão de 10 a 100 % na produção e uma das alternativas de controle que vem sendo utilizada é a enxertia com porta-enxerto resistente.

    2013-01-01

    In recent research on country of origin, some scholars believe that consumers are not clear about product or brand origins. Taking TV brands in China as study object, this paper questions the assumption, and builds a new conceptual model of Brand Origin Recognition Accuracy (BORA) through incorporating a new factor purchase experience. Additionally the paper reveals that: Chinese urban consumers have higher BORA on high involvement products BORAHI; BORAHI is positively correlated with the consumers' education level; male consumers have significantly higher BORAhi than females; BORAHI on foreign brands is negatively correlated with their Ethnocentric Tendencies; consumers' purchase experience is positively correlated with BORAm on local brands; BORAHI on local brands is not significantly affected by consumers' international experience; consumers' educational and income levels are respectively positively correlated with their international experience; and their age is negatively correlated with their international experience.%在近期有关原产地的国际研究中,一些学者认为消费者不清楚产品或品牌的原产地,甚至有人认为全世界都如此.针对此提出质疑,在中国以电视机为产品对象进行了品牌原产地识别准确度(BORA)的测量,并提出了一个新的影响品牌原产地识别准确度的因素——购买经验.因此得出以下结论:中国城市消费者对高介入度产品的品牌原产地识别准确度(BORA高)比较高,BORA高与教育程度呈正相关;男性消费者的BORA高比女性消费者更高;消费者的民族中心主义观念与其外国品牌的BORA高呈负相关;消费者的购买经历与其中国品牌的BORA高呈正相关关系;消费者的国际经历与其中国品牌的BORA高不相关;消费者的受教育程度及经济收入分别与其国际经历呈正相关关系,而消费者的年龄与其国际经历呈负相关关系.本研究结论对于国际营销学者关于

Treatment 1 consisted of free growth plants; treatment 2 (standard of disprouted plants; treatment 3, young curved fruits (<5 cm removed; treatments 4, 5 and 6, plants removing 25%, 50% and 75% of their leaves, respectively. There were no differences in plant height, but plants of treatments 5 and 6 had greater number of nodes per plant, although they were smaller and less vigorous, presenting a smaller number of sproutings. Despite having plants with higher total yield, in treatment 1, most of them were curved and the harvest was more difficult. Plants of treatment 3 had a greater commercial yield, because all the young curved fruits were removed and the plants compensated their yield, producing other fruits with better quality and plants had better sprouting. The higher the defoliation level the greater was the yield reduction.

    2002-12-15

    In a Volkswagen BORA a power train has been realized, which includes a fuel cell system consisting of 6 stacks of 8 kW electrical power output each, an electrical storage device made of 282 supercap cells storing 360 Wh of electrical energy, a DC/DC converter and an electric motor which delivers up to 75 kW. The power distribution between supercaps and fuel cell is managed by an energy management device, which optimizes the distribution taking the actual operation points into account. The fuel cell system operates in a wide range with an efficiency higher than 40%. The power train has been integrated in a five seat car. This car named HY.POWER{sup R}, realized as technology platform, drove over the Simplon pass (elevation 2000 m over sea level) on 16 January 2002. This test drive proved the maturity of this concept to drive using this technology on public roads and that also severe operating conditions can be handled successfully. The key aspects of that concepts are the new manufacturing process of the bipolar plates for the fuel cells, the system configuration of the fuel cell system and the enhanced energy density of the supercap cells. The combination of a fuel cell system and of a supercap storage device, together with the integration of the DC/DC converter lead to a new power train concept. The consumption in the NEDC is equal to the energy of 5-6 l gasoline, which is quite impressive if it is remembered that the car has an empty mass of nearly 2000 kg. The HY.POWER{sup R} has been used heavily for the communication of the new technology to the public. The first event was the test drive across the Simplon pass. The main other events was the international auto motor show in Geneva in March 2002 and the presentation of the vehicle at the Earth Summit in Johannesburg in September 2002. (author)

However, emerging evidence indicates that the beneficial effects of simvastatin extend to the central nervous system. The effects of simvastatin combined with fluoxetine provide an exciting and potential paradigm to decreased anxiety and depression. Thus, the present paper investigates the possibility of synergistic interactions between simvastatin and fluoxetine in models of anxiety and depression. We investigated the effects of subchronically administered simvastatin (1 or 10 mg/kg/day combined with fluoxetine (2 or 10 mg/kg at 24, 5, and 1 hour on adult rats before conducting behavioral tests. The results indicate that simvastatin and/or fluoxetine treatment reduces anxiety-like behaviors in the elevated plus-maze and open-field tests. Our results showed that simvastatin and/or fluoxetine induced a significant increase in the swimming activity during the forced swimming test (antidepressant effect, with a concomitant increase in climbing time in simvastatin-treated animals only (noradrenergic activation. We hypothesize that anxiolytic and antidepressant effects of simvastatin and/or fluoxetine produce their behavioral effects through similar mechanisms and provide

  16. Tip shift in the zero inertia powertrain

    For any transmission type the vehicle's responsiveness during large and/or fast engine speed shifts may appear reluctant or even counteractive. This is caused by unwanted inertial torques stemming from accelerating or decelerating the rotating elements within the engine and transmission. Reminiscent of comparable behaviour seen in aircraft jet-propulsion, this phenomenon is also referred to as 'jet-start'. To overcome this behaviour, a CVT powertrain is augmented with a powersplitting planetary gear stage and compact steel flywheel. The new transmission-coded zero inertia (ZI) powertrain-seamlessly combines two contradictive features: the driveability in terms of the pedal-to-wheel response is greatly improved and a large leap towards optimal fuel economy can be made. The latter is achieved by cruising the vehicle at extremely low engine speeds owing to the large ratio-coverage of the CVT. As for the driveability, the flywheel acts as a peak shaver. During engine speed shifts it delivers power at (semi-) pedal kick down (downshift) and absorbs kinetic energy of the engine sided powertrain elements at pedal back-out (upshift). In this paper, the behaviour of the ZI system is evaluated in 'tip-shift' mode. In field experiments the tip-shift in a VW Bora test vehicle with ZI powertrain is compared with a commercially available Mini One with CVT. A test panel of 10 people drove the vehicles, executed predefined tasks and evaluated their findings. The results of these experiments are also reported in this paper. (orig.)

  17. Efficient Förster resonance energy transfer in 1,2,3-triazole linked BODIPY-Zn(II) meso-tetraphenylporphyrin donor-acceptor arrays.

    Cu(I) catalyzed azide-alkyne cycloaddition (CuAAC) reactivity was successfully employed to synthesize three donor-acceptor energy transfer (EnT) arrays that contain one (Dyad), three (Tetrad) and four (Pentad) 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) donors connected to a Zn-tetraphenylporphyrin acceptor via 1,2,3-triazole linkages. The photophysical properties of the three arrays, along with individual donor and acceptor chromophores, were investigated by UV-vis absorption and emission spectroscopy, fluorescence lifetimes, and density functional theory (DFT) electronic structure modeling. Comparison of the UV-vis absorption spectra and frontier molecular orbitals from DFT calculations of the three arrays with ZnTPP, ZnTTrzlP, and Trzl-BODIPY shows that the electronic structure of the chromophores is essentially unperturbed by the 1,2,3-triazole linkage. Time-dependent DFT (TDDFT) calculations on the Dyad reproduce the absorption spectra in THF and show no evidence of excited state mixing of the donor and acceptor. The BODIPY singlet excited state emission is significantly quenched in all three arrays, consistent with EnT to the porphyrin core, with efficiencies of 95.8, 97.5, and 97.2% for the Dyad, Tetrad, and Pentad, respectively. Fluorescence excitation spectra of the three arrays, measured at the porphyrin emission, mirror the absorption profile of both the porphyrin and BODIPY chromophores and are consistent with the Förster resonance energy transfer (FRET) mechanism. Applying Förster theory to the spectroscopic data of the chromophores gives EnT efficiency estimates that are in close agreement with experimental values, suggesting that the through-space mechanism plays a dominant role in the three arrays.

  18. Seasonal Short-Lived Radium Activity in the Venice Lagoon: The Role of Residence Time

    Radium is considered to be an excellent tracer of submarine groundwater discharge (SGD) and, therefore, has been used in many studies of this process in the past decade. Comprehensive surveys of excess 223,224Ra activity were completed in the surface waters of the Venice Lagoon over 6 seasons in order to quantify seasonal variation of SGD into the lagoon. The mass balance of radium found that SGD was 5-26 times greater than total river discharge (35.5 m3 s-1), and that total SGD could differ by almost an order of magnitude pending season. Several possible parameters, which may cause the seasonal variation, were tested. These included precipitation events, average tidal elevation, average tidal excursion, wind speed and direction, yet none provided a satisfactory explanation for the difference. Residence time based on a hydrodynamic model, however, was very strongly correlated with the observed variation. When the average residence time in the lagoon was low (5 days) the SGD was calculated to be 930 m3 s-1 and when the average residence time was high (9 days) the SGD was quantified as 160 m3 s-1. Radioactive decay is already accounted for in the mass balance model and therefore this correlation must be explained by another process. The Venice Lagoon is characterized by low residence time during periods of spring tides and bora or northerly winds, both of which create exceptionally strong currents in the Venice Lagoon. The currents as well as the large tidal excursion which occurs at spring tides drive a recirculation of seawater through the surface sediments, which greatly increases short-lived Ra activity in the surface waters. This evidence suggests, therefore, that short-lived Ra mass balance studies, which are based on a single survey, may under or overestimate the mean annual SGD pending the hydrodynamics of the investigated location.

    Full Text Available The coordinated activities at centromeres of two key cell cycle kinases, Polo and Aurora B, are critical for ensuring that the two sister kinetochores of each chromosome are attached to microtubules from opposite spindle poles prior to chromosome segregation at anaphase. Initial attachments of chromosomes to the spindle involve random interactions between kinetochores and dynamic microtubules, and errors occur frequently during early stages of the process. The balance between microtubule binding and error correction (e.g., release of bound microtubules requires the activities of Polo and Aurora B kinases, with Polo promoting stable attachments and Aurora B promoting detachment. Our study concerns the coordination of the activities of these two kinases in vivo. We show that INCENP, a key scaffolding subunit of the chromosomal passenger complex (CPC, which consists of Aurora B kinase, INCENP, Survivin, and Borealin/Dasra B, also interacts with Polo kinase in Drosophila cells. It was known that Aurora A/Bora activates Polo at centrosomes during late G2. However, the kinase that activates Polo on chromosomes for its critical functions at kinetochores was not known. We show here that Aurora B kinase phosphorylates Polo on its activation loop at the centromere in early mitosis. This phosphorylation requires both INCENP and Aurora B activity (but not Aurora A activity and is critical for Polo function at kinetochores. Our results demonstrate clearly that Polo kinase is regulated differently at centrosomes and centromeres and suggest that INCENP acts as a platform for kinase crosstalk at the centromere. This crosstalk may enable Polo and Aurora B to achieve a balance wherein microtubule mis-attachments are corrected, but proper attachments are stabilized allowing proper chromosome segregation.

    Full Text Available The high temperature of growth environment can affect the postharvest quality of tomato fruits. In this situation, an alternative for the farmers is the use of hybrid cultivars that produce long shelf life fruit with longer postharvest shelf life when compared to normal varieties of fruits. The objective of this research was to compare the postharvest conservation of fruits of structural long shelf life tomato hybrids and with the mutant rin. The fruits evaluated were from fifteen tomato genotypes produced under the edaphoclimatic conditions of the southern State of Tocantins, being four of them long shelf life type hybrids (with rin allele which were: Tyler, Rebeca, Carmem and AF 13527; nine of them structural long shelf life hybrids: Lumi, Débora Max, Michelli, Tammy, AF 12525, AF 11097, AF 13363, AF 13364 and AF 13525; and two normal fruit cultivars: Santa Clara and Drica. The fruits were harvested at the breaker stage and stored in a controlled environment (20 °C and relative humidity of 60%. The half-life firmness of fruits of genotypes with a structural genotypic long shelf life background ranged from 6.25 to 13.44 days for the genotypes Tammy and AF13525, respectively, not differing from the long shelf life genotypes with rin allele. Despite the fact that daytime temperatures are higher than those recommended for the tomatoes crops, it was observed that if the fruits are stored in appropriate conditions (20 °C and relative humidity of 60%, the color and firmness of the fruits with a long shelf life genotypes with rin allele and structural genotypic background evolve more slowly than the fruits of normal genotypes. Under these conditions, it took the fruits 7 to 8 days to acquire a red color on more than 80% of the surface after being harvested.

    Biochemical analysis was performed on field caught Aedes (Stegomyia) aegypti and Aedes (Stegomyia) albopictus (Diptera: Culicidae) mosquitoes to determine activities of enzymes including mixed function oxidases (MFO), nonspecific esterases (alpha- and beta-), glutathione-S-transferases (GST), and insensitive acetylcholinesterase (AChE). Biochemical tests were performed on F1 generation of Ae. aegypti field caught mosquitoes, while in Ae. albopictus F2 progenies were used. Twenty-six samples of Ae. aegypti mosquito were collected from areas across different parts of Thailand including Bangkok (central), and the provinces of Chiang Rai (north), Nakhon Sawan (north-central), Nakhon Ratchasrima (northeast), Chonburi (east), Chanthaburi (east), and Songkhla (south). Eight wild caught samples of Ae. albopictus were from Songkhla, Nakhon Sawan, Nakhon Ratchasrima and Kanchanaburi (west) provinces. The susceptibility to pyrethroids (deltamethrin, permethrin), organophosphate (fenitrothion) and carbamate (propoxur) insecticides were revealed in these samples. The biochemical test results were compared with those of the susceptible Bora (French Polynesia) strain. There was significant enhancement of MFO in pyrethroid resistant Ae. aegypti samples, except those from Songkhla and Hauykwang district in Bangkok. Biochemical assay results suggested that nonspecific esterases conferred fenitrothion resistance in Ae. aegypti in Nakhon Sawan, while insensitive AChE and/or nonspecific esterases could play role in fenitrothion resistance in Nakhon Ratchasrima. There was no consistent association of GST with pyrethroid resistance in Ae. aegypti. Low enzyme activities found in Ae. aegypti in Songkhla and in Ae. albopictus corresponded to their insecticide susceptibility status. The increased enzyme activity in field samples reflecting local history of insecticide employment was discussed.

    Zinc α2 glycoprotein (ZAG) is an adipokine with a class I MHC protein fold and is associated with obesity and diabetes. Although its intrinsic ligand remains unknown, ZAG binds the dansylated C11 fatty acid 11-(dansylamino)undecanoic acid (DAUDA) in the groove between the α1 and α2 domains. The surface of ZAG has approximately 15 weak zinc-binding sites deemed responsible for precipitation from human plasma. In the present study the functional significance of these metal sites was investigated. Analytical ultracentrifugation (AUC) and CD showed that zinc, but not other divalent metals, causes ZAG to oligomerize in solution. Thus ZAG dimers and trimers were observed in the presence of 1 and 2 mM zinc. Molecular modelling of X-ray scattering curves and sedimentation coefficients indicated a progressive stacking of ZAG monomers, suggesting that the ZAG groove may be occluded in these. Using fluorescence-detected sedimentation velocity, these ZAG-zinc oligomers were again observed in the presence of the fluorescent boron dipyrromethene fatty acid C16-BODIPY (4,4-difluoro-5,7-dimethyl-4-bora-3a,4a-diaza-s-indacene-3-hexadecanoic acid). Fluorescence spectroscopy confirmed that ZAG binds C16-BODIPY. ZAG binding to C16-BODIPY, but not to DAUDA, was reduced by increased zinc concentrations. We conclude that the lipid-binding groove in ZAG contains at least two distinct fatty acid-binding sites for DAUDA and C16-BODIPY, similar to the multiple lipid binding seen in the structurally related immune protein CD1c. In addition, because high concentrations of zinc occur in the pancreas, the perturbation of these multiple lipid-binding sites by zinc may be significant in Type 2 diabetes where dysregulation of ZAG and zinc homoeostasis occurs.

With modification of the standard cetyltrimethylammonium bro-mide(CTAB)method by adding boras(disodium tetraborate decahydrate) andβ-mercaptoethanol to eliminate the interfer-ence of polyphenol and polysaccharides, an effective protocol was developed. This modified protocol could extract high quantities of RNA is of high quality. The RNA quality was confirmed by Northern blotting analysis and reverse tran-scription polymerase chain reaction(RT-PCR).The modified protocol could be successfully extended to other plants con-taining secondary metabolites.%由于苏铁(Cycas revoluta)叶片中含有大量的多糖多酚等次生代谢物,常规RNt提取方法很难获得优质的RNA.在常规的CTAB法中加入了硼砂和β-巯基乙醇来消除多酚和多糖的干扰,得到了一个从苏铁叶片中有效提取RNA的方法,每克鲜叶片可获得约930 ug RNA.A260/280和A260/230的纳米波长的吸收比值都约为2,表明RNA的质量较好.获得的RNA可用于Northern blot和反转录PCR等分析,也说明RNA的质量比较好.此外,改进的提取方法也适合于含有次生代谢产物的其它植物,同样可以获得优质RNA.

    For the study of CO{sub 2} absorption and fixation in the marine ecosystem, studies of coral reefs by RITE (Research Institute of Innovative Technology for the Earth) were subjected to discussion at the above-named workshops. It is after the elapse of a long geological time on the earth that CO2 in the atmosphere has arrived at the current level of concentration thanks to fixation and calcification by living organisms and to dissolution into the seawater. In the formation of CaCO{sub 3} that constitutes the coral skeleton, 1 mol Ca combines with 2 mol bicarbonates for the production of 1 mol CaCO{sub 3} and 1 mol CO{sub 2}. The reaction may suggests a consequential increase of CO2 in the atmosphere but such CO{sub 2} is in reality consumed by being converted into organic substances in a photosynthetic process performed by symbiotic algae. Calculation was made for the whole of Bora Bay, Miyakojima Island, and the result was that 700kg-C/day comes to be stored in the form of organic matters in the community of coral reef organisms. In a coral reef, even when it emits CO2 into the atmosphere, there is organic matter production which exceeds the lost CO{sub 2}. Coral reefs fix carbon out of the seawater at the rate of 0.42Gt-C/year, which is the aggregate of 0.3Gt organic matters and 0.12Gt CaCO{sub 3}. (NEDO)

A control group was prepared with a flowable composite at room temperature. DC was determined using a Fourier transform infrared spectrometer, KHN was measured with a Knoop indenter, P was evaluated by percentage reduction of hardness after 24 h of ethanol storage, and DP was obtained by bottom/top ratio. Data were statistically analyzed by analysis of variance and Tukey’s test (α = 0.05.Results: Regardless of light-curing, the highest preheating temperature increased DC compared to room temperature on bottom surface. LED showed a higher DC compared to QTH. Overall, DC was higher on top surface than bottom. KHN, P, and DP were not affected by curing mode and temperature, and flowable composite showed similar KHN, and lower DC and P, compared to bulk fill.Conclusion: Composite preheating increased the polymerization degree of 4-mm-increment bulk fill, but it led to a higher plasticization compared to the conventional flowable composite evaluated.

Composite resin specimens were randomly prepared and assigned to nine experimental groups (n = 5: considering three light-curing units (conventional quartz tungsten halogen [QTH]: 550 mW/cm2 – 20 s; high irradiance QTH: 1160 mW/cm2 – 10 s; and light-emitting diode [LED]: 360 mW/cm2 – 40 s and three sample thicknesses (0.5 mm, 1 mm, and 2 mm. All samples were polymerized with the light tip 8 mm away from the specimen. Knoop microhardness was then measured on the top and bottom surfaces of each sample. The top surfaces, with some exceptions, were almost similar; however, in relation to the bottom surfaces, statistical differences were found between curing units and thicknesses. In all experimental groups, the 0.5-mm-thick increments showed microhardness values statistically higher than those observed for 1- and -2-mm increments. The conventional and LED units showed higher hardness mean values and were statistically different from the high irradiance unit. In all experimental groups, microhardness mean values obtained for the top surface were higher than those observed for the bottom surface. In conclusion, higher levels of irradiance or thinner increments would help improve hybrid composite resin polymerization.Keywords: photo-polymerization, light-curing distance, light-curing units, composite resin, composite thickness, microhardness

All MEs displayed nanometric size (32.3–40.7 nm and slight positive zeta potential (+4.1 mV to +6.8 mV. Skin penetration of paclitaxel from the MEs was assessed for 1–12 hours using porcine skin and Franz diffusion cells. Among the PTD-containing formulations, paclitaxel skin (stratum corneum + epidermis and dermis penetration at 12 hours was maximized with ME-T, whereas ME-TAT provided the lowest penetration (1.6-fold less. This is consistent with the stronger ability of ME-T to increase transepidermal water loss (2.4-fold compared to water and tissue permeability. The influence of PTD addition on the ME irritation potential was assessed by measuring interleukin-1α expression and viability of bioengineered skin equivalents. A 1.5- to 1.8-fold increase in interleukin-1α expression was induced by ME-T compared to the other formulations, but this effect was less pronounced (5.8-fold than that mediated by the moderate irritant Triton. Because ME-T maximized paclitaxel cutaneous localization while being safer than Triton, its efficacy was assessed against basal cell carcinoma cells and a bioengineered three-dimensional melanoma model.

    The seasonal variability of the carbonate system in the waters of the Gulf of Trieste (GoT) was studied at PALOMA station from 2008 to 2009, in order to highlight the effects of biological processes, meteorological forcings and river loads on the dynamics of pHT, CO2 partial pressure (pCO2), dissolved inorganic carbon (DIC), carbonate ion concentration (CO3=), aragonite saturation state (ΩAr) and total alkalinity (AT). During winter, low seawater temperature (9.0 ± 0.4 °C) and a weak biological activity (-10.7 trends were observed in the bottom waters. In August 2008, during a hypoxic event (dissolved oxygen DO = 86.9 μmol O2 kg-1), the intense remineralisation of organic carbon caused the rise of pCO2 (1043 μatm) and the decreases of pHT and ΩAr values down to 7.732 and 1.79 respectively. On an annual basis, surface pCO2 was mainly regulated by the pronounced seasonal cycle of seawater temperature. In winter, surface waters in the GoT were under-saturated with respect to atmospheric CO2, thus acting as a sink of CO2, in particular when strong-wind events enhanced air-sea gas exchange (FCO2 up to -11.9 mmol m-2 d-1). During summer, the temperature-driven increase of pCO2 was dampened by biological CO2 uptake, as consequence a slight over-saturation (pCO2 = 409 μatm) turned out. River plumes were generally associated to higher AT and pCO2 values (up to 2859 μmol kg-1 and 606 μatm respectively), but their effect was highly variable in space and time. During winter, the ambient conditions that favour the formation of dense waters on this continental shelf, also favour a high absorption of CO2 in seawater and its consequent acidification (pHT decrease of -0.006 units during a 7-day Bora wind event). This finding indicates a high vulnerability of North Adriatic Dense Water to atmospheric CO2 increase and ocean acidification process.

The 1-methylimidazole (1-MeIm) complex 3 was prepared as a control and for structural characterization by X-ray crystallography. Complexes 1 and 2 showed strong visible absorption bands at 500 nm (ε = 2.7 × 10(4) M(-1) cm(-1)) and 540 nm (1.4 × 10(4) M(-1) cm(-1)). Complex 1 is emissive with a band at 510 nm (ΦF = 0.09) in 1% dimethyl sulfoxide/Dulbecco's Modified Eagle's Medium (pH 7.2). Singlet oxygen generation upon photoirradiation with visible light (400-700 nm) was evidenced from 1,3-diphenylisobenzofuran titration experiments showing significant photosensitizing ability of the BODIPY complexes. Both 1 and 2 were remarkably photocytotoxic in visible light (400-700 nm, 10 J cm(-2)) in skin keratinocyte HaCaT and breast cancer MCF-7 cells giving IC50 values in nanomolar concentration. The complexes were, however, essentially nontoxic to the cells in the dark (IC50 > 80 μM). Complex 2 having a diiodo-BODIPY unit is nonemissive but an efficient photosensitizer with high singlet oxygen generation ability in visible light (400-700 nm). Confocal microscopy using the emissive complex 1 showed significant mitochondrial localization of the complex. Cell death via apoptotic pathway was observed from the Annexin-V-FITC/PI assay. The formation of Pt-DNA adducts was evidenced from the binding experiments of the complexes 1 and 2 with 9-ethylguanine as a model nucleobase from (1)H NMR and mass spectral studies.

Elevated activation of the system from, for example, biomaterials or medical devices can result in both local and systemic adverse effects and eventually loss of function or rejection of the biomaterial. Here, the researchers have studied the effect of surface nanotopography on the activation of the IC system. By a simple nonlithographic process, gold nanoparticles with an average size of 58 nm were immobilized on a smooth gold substrate, creating surfaces where a nanostructure is introduced without changing the surface chemistry. The activation of the IC on smooth and nanostructured surfaces was viewed with fluorescence microscopy and quantified with quartz crystal microbalance with dissipation monitoring in human serum. Additionally, the ability of pre-adsorbed human immunoglobulin G (IgG (a potent activator of the IC to activate the IC after a change in surface hydrophobicity was studied. It was found that the activation of the IC was significantly attenuated on nanostructured surfaces with nearly a 50% reduction, even after pre-adsorption with IgG. An increase in surface hydrophobicity blunted this effect. The possible role of the curvature of the nanoparticles for the orientation of adsorbed IgG molecules, and how this can affect the subsequent activation of the IC, are discussed. The present findings are important for further understanding of how surface nanotopography affects complex protein

    Hypoxanthine phosphoribosyl transferase (HPRT) deficiency results in Lesch-Nyhan disease (LND). The link between the HPRT defect and the self-injurious behavior in LND is still unknown. HPRT-deficient rat B103 neuroblastoma cells serve as a model system for LND. In B103 cell membranes, HPRT deficiency is associated with a decrease of basal and guanosine triphosphate-stimulated adenylyl cyclase (AC) activity (Pinto and Seifert, J Neurochem 96:454-459, 2006). Since recombinant AC2 possesses a high basal activity, we tested the hypothesis that AC2 function and expression is impaired in HPRT deficiency. We examined AC regulation in B103 cell membranes, cAMP accumulation in intact B103 cells, AC isoform expression, and performed morphological studies. As most important pharmacological tool, we used 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene forskolin (BODIPY-FS) that inhibits recombinant AC2 but activates ACs 1 and 5 (Erdorf et al., Biochem Pharmacol 82:1673-1681, 2011). In B103 control membranes, BODIPY-FS reduced catalysis, but in HPRT(-) membranes, BODIPY-FS was rather stimulatory. 2'(3')-O-(N-methylanthraniloyl) (MANT)-nucleoside 5'-[γ-thio]triphosphates inhibit recombinant ACs 1 and 5 more potently than AC2. In B103 control membranes, MANT-guanosine 5'-[γ-thio]triphosphate inhibited catalysis in control membranes less potently than in HPRT(-) membranes. Quantitative real-time PCR revealed that in HPRT deficiency, AC2 was virtually absent. In contrast, AC5 was up-regulated. Forskolin (FS) and BODIPY-FS induced cell clustering and rounding and neurite extension in B103 cells. The effects of FS and BODIPY-FS were much more prominent in control than in HPRT(-) cells, indicative for a differentiation defect in HPRT deficiency. Neither FS nor BODIPY-FS significantly changed cAMP concentrations in intact B103 cells. Collectively, our data show that HPRT deficiency in B103 cells is associated with impaired AC2 function and expression and reduced sensitivity to

    Full Text Available O objetivo deste trabalho foi detectar uma possível especificidade alimentar de duas espécies crípticas de cochonilhas do gênero Planococcus, refletida em seu desenvolvimento em frutos de cacaueiro, cafeeiro e citros. A cochonilha Planococcus minor (Maskell, obtida de frutos de cacau (Theobroma cacao L. cv. Comum, e Planococcus citri (Risso, de lavoura de café (Coffea arabica L. cv. Mundo Novo e de mudas de citros (Citrus sinensis L. Osbeck cv. Bahia, foram criadas em abóboras (Cucurbita maxima L., em laboratório. Rosetas com frutos de café foram mantidas sobre uma lâmina de 5 mm de ágar-água em placas de Petri, vedadas com filme plástico de polietileno. Em frutos de citros e cacau foram utilizadas gaiolas plásticas cilíndricas (1,5 cm x 3,0 cm, vedadas com voile na parte superior, as quais foram fixadas nos frutos por meio de um elástico. Os bioensaios foram conduzidos em câmaras climatizadas a 25 ± 1ºC, 70 ± 10% UR e 12 horas de fotofase, utilizando-se de 30 repetições. Para as cochonilhas provenientes de cafeeiro, o substrato café proporcionou o maior período ninfal de fêmeas (20,8 dias e maior longevidade (31,7 dias. Para fêmeas oriundas de cacau, o substrato cacau promoveu o menor período ninfal (21,1 dias e maior longevidade (25,0 dias. Para aquelas oriundas de citros, o substrato cacau promoveu o menor período ninfal (18,4 dias, e o substrato citros, a maior longevidade (32,0 dias. As maiores porcentagens de mortalidade (50% foram obtidas das ninfas oriundas de frutos de cacau e citros, criadas em café e cacau, e as menores foram das ninfas oriundas de frutos de café, independentemente do substrato em que foram criadas. A cochonilha P. minor mostra uma associação mais estreita com o cacau e, eventualmente, café, em relação ao citros, o que explicaria sua maior ocorrência em cacau. No entanto, P. citri não evidencia nenhuma especificidade para os três substratos testados.

    The effects of different physical and biogeochemical drivers on the carbonate system were investigated in a semi-enclosed coastal area characterized by high alkalinity riverine discharge (Gulf of Trieste, Northern Adriatic Sea, Mediterranean Sea). Our 2-year time-series showed that a large part of the seasonal carbonate chemistry variation was controlled by the large seasonal change of seawater temperature, though air-sea CO2 exchange, biological activity (primary production-respiration), and riverine inputs also exerted a significant influence. With the exception of summer, the Gulf of Trieste was a sink of atmospheric carbon dioxide, showing a very strong CO2 fluxes from atmosphere into the sea (-16.10 mmol m-2 day-1) during high wind speed event of north easterly Bora wind. The CO2 influx was particularly evident in winter, when the biological activity was at minimum and the low seawater temperature enhanced CO2 solubility. During spring, the drawdown of CO2 by primary production overwhelmed the CO2 physical pump, driving a significant decrease of dissolved inorganic carbon (DIC), [CO2], and increase of pHT25 °C. In summer the primary production in surface waters occurred with the same intensity as respiration in the bottom layer, so the net biological effect on the carbonate system was very low and the further reduction of seawater CO2 concentration observed was mainly due to carbon dioxide degassing induced by high seawater temperature. Finally, during autumn the respiration was the predominant process, which determined an overall increase of DIC, [CO2], and decrease of pHT25 °C. This was particularly evident when the breakdown of summer stratification occurred and a large amount of CO2, generated by respiration and segregated below the pycnocline, was released back to the whole water column. Local rivers also significantly affected the carbonate system by direct input of total alkalinity (AT) coming from the chemical weathering of carbonate rocks, which

    On the basis of a new classification of seismically induced landslides we outline particular effects related to the delayed and distant triggering of landslides. Those cannot be predicted by state-of-the-art methods. First, for about a dozen events the 'predicted' extension of the affected area is clearly underestimated. The most problematic cases are those for which far-distant triggering of landslides had been reported, such as for the 1988 Saguenay earthquake. In Central Asia reports for such cases are known for areas marked by a thick cover of loess. One possible contributing effect could be a low-frequency resonance of the thick soils induced by distant earthquakes, especially those in the Pamir - Hindu Kush seismic region. Such deep focal and high magnitude (>>7) earthquakes are also found in Europe, first of all in the Vrancea region (Romania). For this area and others in Central Asia we computed landslide event sizes related to scenario earthquakes with M>7.5. The second particular and challenging type of triggering is the one delayed with respect to the main earthquake event: case histories have been reported for the Racha earthquake in 1991 when several larger landslides only started moving 2 or 3 days after the main shock. Similar observations were also made after other earthquake events in the U.S., such as after the 1906 San Francisco, the 1949 Tacoma, the 1959 Hebgen Lake and the 1983 Bora Peak earthquakes. Here, we will present a series of detailed examples of (partly monitored) mass movements in Central Asia that mainly developed after earthquakes, some even several weeks after the main shock: e.g. the Tektonik and Kainama landslides triggered in 1992 and 2004, respectively. We believe that the development of the massive failures is a consequence of the opening of tension cracks during the seismic shaking and their filling up with water during precipitations that followed the earthquakes. The third particular aspect analysed here is the use of large

    Full Text Available RESUMOOs artrópodes considerados vetores de viroses são pragas iniciais na cultura do tomateiro e possuem capacidade de causar danos diretos e indiretos, principalmente quando ocorrem falhas no manejo. O objetivo deste estudo foi estudar a incidência e infestação de vetores de viroses em dois sistemas de manejo de pragas em plantios de tomateiro estaqueado. O experimento foi conduzido em plantio de tomateiro da variedade 'Débora Mix', grupo Santa Clara, com espaçamento de 1,0 x 0,5 m (linhas x plantas, em condução com duas hastes (Tutoramento vertical. Os sistemas avaliados foram: Manejo Ecológico de Pragas (MEP - monitoramento das pragas e tomada de decisão para a aplicação de inseticidas com base no nível de infestação e Convencionalcalendário de aplicações que iniciaram sete dias após o transplantio e seguiram sendo realizadas duas vezes por semana. A maior incidência de B. tabaci ocorreu no sistema MEP, enquanto que a maior incidência de Liriomyza sp. e diferentes espécies de pulgões ocorreu no sistema convencional, mas para F. schultzei não houve diferença na incidência entre os manejos. Houve infestação dos vetores de viroses durante todo o período de condução da cultura e, no geral, considerando todos os insetospraga, a redução no número de aplicações foi de 88,14% no MEP. O sistema de manejo adotado não interfere na incidência e infestação de vetores de viroses na cultura, mas a implantação do sistema MEP viabiliza a utilização criteriosa dos defensivos agrícolas, permitindo redução do número de pulverizações com consequente redução dos custos de produção.

    Full Text Available O Instituto Nacional de Alimentação e Nutrição (Inan está propondo o uso, em nível nacional, de fórmula de alimentação alternativa, denominada "Multimistura", à base de farelos de arroz, e/ou trigo, sementes de gergelim e abóbora, folhas de mandioca, beterraba, cenoura, verduras nativas e pó de casca de ovo, como solução para combater a fome da população carente. Embora o crítico estado nutricional da população-alvo possa fazer qualquer questionamento técnico ou ético parecer por demais filosófico, uma série de considerações nutricionais, toxicológicas e até de viabilidade prática sugerem que a posição adotada pelo Inan deveria ser revista. A solução da multimistura, talvez válida para situações transitórias de extrema pobreza, carece de universalidade para ser utilizada, independentemente de faixa etária, estado nutricional e período de duração da intervenção.The nationwide use of a "Multimixture," a formula based on alternative foods such as rice and/or wheat bran, sesame and squash seeds, cassava, beet and carrot leaves, several indigenous leafy vegetables, and ground egg shells has been proposed by the National Institute of Food and Nutrition (INAN as an official solution to fight hunger among poor Brazilians. The fragile nutritional state of the target population may make technical or ethical questions appear purely academic, yet nutritional, toxicological, and practical feasibility considerations appear to warrant a revision of the INAN proposal. While the Multimixture approach may prove valid as a temporary solution in cases of extreme poverty, it is not universally applicable for the intended use, failing to take into account the age and nutritional status of the subjects or duration of the intervention.

    Full Text Available A maioria dos estudos relacionados à agregação do solo associa o efeito de manejos ou tipos de uso da terra ao teor de matéria orgânica. No entanto, a avaliação de microrganismos e seus processos, feita diretamente em estruturas indeformadas do solo, permite maior entendimento do real efeito de diferentes tipos de manejos exercidos sobre esse. Assim, o objetivo deste trabalho foi avaliar modificações impostas por diferentes tipos de uso da terra (pastagem, mata de eucalipto, mata com araucária, plantio convencional com cenoura e plantio convencional com abóbora em atributos químicos (pH, Ca, Mg, Al, P, K, S e matéria orgânica e físicos (diâmetro médio geométrico - DMG, diâmetro médio ponderado - DMP, densidade do solo e densidade de partículas e na qualidade microbiana (atividade e carbono microbianos, micélio extrarradicular total de fungos micorrízicos arbusculares e quociente metabólico - qCO2 de classes de tamanho de agregados (I- 4,00 a 2,36 mm; II- 2,36 a 1,18 mm; III- 1,18 a 0,60 mm; IV- 0,60 a 0,30 mm; e V- 0,30 a 0,15 mm de um Latossolo Vermelho-Amarelo, no sul de Minas Gerais. Os resultados evidenciaram que os tipos de uso da terra interferem na formação, no tamanho e na qualidade microbiana dos agregados. Em agregados menores (classes IV e V, há redução de micélio extrarradicular de fungos e biomassa microbiana e aumento da atividade e do quociente metabólico, independentemente do tipo de uso da terra. A qualidade microbiana de agregados maiores do solo sob mata de araucária, com tamanho entre 0,60 e 4,00 mm (I, II e III, é semelhante a todas as classes de tamanho de agregados do solo sob mata de eucalipto, enquanto a de agregados menores de 0,60 mm (IV e V é semelhante a todas de tamanho de agregados da pastagem. Agregados do cultivo convencional, diferentemente dos demais tipos de uso da terra, apresentam baixa qualidade microbiana e relação com a fertilidade do solo.

    Full Text Available Due to the growing number of immigrants in the United States, made up principally of Latinos, Asians and Africans, there has been a growing demand for products that are popular in their countries of origin. In order to meet this demand, there has been a tremendous increase in imports of agricultural products to the United States. Cassava is a good example. Imports of cassava to the US have increased 370% in the last six years. The University of Massachusetts began to evaluate vegetable crops popular among Puerto Ricans and Dominicans in 1996, and in 2002 began to evaluate crops popular among the large and growing Brazilian population in the state and region. This paper summarizes results of research on crops popular with Brazilian immigrants in the US, in addition to the evaluation of the marketing chain and impact of media outlets to promote and sell these crops. Surveys of Brazilian customers in target markets demonstrated that the majority of Brazilian immigrants in the Northeastern United States are from the state of Minas Gerais. Due to this fact, the crops chosen for research in Massachusetts were ones that were popular in this state: jiló, maxixe, taioba, abóbora and okra. In order to successfully introduce these crops into the marketplace it is critical to devote resources to promotion and marketing. In spite of their popularity among Brazilians, these vegetable crops are not normally found in the market so it is necessary to let the community know that they are available and in what locations. The most effective media outlet evaluated in this work to reach Brazilians was the television station Rede Globo International, available in the United States; however, other avenues evaluated to promote this project to Brazilians, such as Brazilian newspapers and radio programs, were also effective and less expensive. The opportunity to export agricultural products to the United States is a growing opportunity for farmers in Brazil. In order to

O objetivo deste trabalho foi estudar os efeitos da aplicação de lâminas de água e da injeção de dióxido de carbono (CO2 no sistema de irrigação sobre a cultura de tomate, cultivar Débora-Plus. Para isso foi conduzido um experimento em Piracicaba, de março a outubro de 1999 sob duas estufas, utilizando seis lâminas de água (40; 60; 80; 100; 120% e 140% da lâmina requerida pela cultura e dois níveis de dióxido de carbono (C0 = 0 g de CO2.L-1 de água e C1 = 7,73 g.L-1 de CO2 aplicados via água. O delineamento experimental para o efeito das lâminas de irrigação foi o de blocos ao acaso com quatro repetições. Os tratamentos de CO2 foram aplicados em estufas separadas. A irrigação foi realizada utilizando sistema de irrigação por gotejamento, com manejo controlado por tanques evaporimétricos reduzidos e tensiômetros. A aplicação do CO2 foi realizada por intermédio de um cilindro comercial e injetor tipo Venturi, durante o tempo necessário à aplicação da lâmina mínima de água. A aplicação de CO2 via água de irrigação proporcionou aumentos de 8,2%; 13% e 8,5% respectivamente na produtividade, peso de frutos de tamanho pequeno e conteúdo de matéria seca de frutos. Entretanto não foram verificados efeitos significativos sobre o número de frutos e o peso de frutos de tamanho médio. Análises da solução do solo indicaram que o uso do CO2 possivelmente contribui para a melhoria das condições nutricionais do tomateiro. Verificou-se também a viabilidade econômica da aplicação deste gás. As lâminas de irrigação não proporcionaram efeitos significativos sobre a produtividade, o número total, o peso médio e o conteúdo de matéria seca de frutos.

    Las serpientes pertenecen a la clase reptiles, orden escamados y suborden ofidios. Surgieron durante el periodo cretáceo hace aproximadamente 120 millones de años. La evolución de las formas venenosas es un poco más reciente, posiblemente hace unos 30 millones de años. Actualmente se conocen unas 3200 especies de serpientes de las cuales unas 1300 son venenosas, agrupadas en cuatro familias: Colubridae (cazadoras opistoglifas, Elapidae (corales, Hydrophiidae (serpientes marinas y Viperidae (víboras subfamilia Crotalinae (de fosa. La víbora Bothriechis schlegelii, es una serpiente arborícola que se distribuye desde Centroamérica hasta Suramérica (Venezuela, Ecuador y Colombia. En Colombia la especie se encuentra en las 3 cordilleras, en los valles interandinos y en las llanuras del Caribe y del Pacífico hasta los 2.640 metros sobre el nivel del mar. Su talla máxima es de 83 cm y el accidente por ella ocupa el primer lugar en las zonas cafeteras y en el norte de Antioquia. Además a esta especie se le ha demostrado variación en el patrón de coloración en las regiones del Suroeste y norte de Antioquia.

    Variabilidad del Veneno: Los estudios de variabilidad en los venenos de las serpientes han comprendido el análisis con respecto a la zona geográfica, a la ontogenia, al régimen alimenticio y a la época del año, tanto de manera intraespecie como interespecie. Se ha observado que algunas especies aisladas reproductivamente por barreras naturales, presentan variaciones en la composición del veneno. En la especie Daboia russelli se reportó variabilidad geográfica en el veneno, hallazgo importante para el tratamiento, ya que el antiveneno producido con especimenes continentales, no es efectivo para

'Débora Max', THX-01, THX-02 e THX-04 foram semelhantes entre si quanto ao teor de licopeno e superaram 'Giuliana', 'Sahel', THX-03 e THX-06.The management of the tomato plant under greenhouse, with emphasis on fruit thinning, contributes significantly to the production of fruits of superior quality, expressing the potential of each cultivar. We determined the effect of fruit thinning on yield and its components in tomato hybrids of the Santa Cruz and Italian types of indeterminate growth, and we performed the qualitative characterization of the fruits, aiming in natura market. Twelve fresh-market tomato genotypes (six experimental hybrids and six commercial cultivars and two training methods (with and without manual fruit thinning were evaluated. A randomized complete block design was used in this trial, with split-plots and three replications. The plots were represented by genotypes and the subplots were constitued by training methods. Number of fruits per plant, yield of marketable and not marketable fruits, average fruit weight, fruit length and fruit width were measured. For quantitative characterization, pH, soluble solids concentration (SS, tritratable acidity (AT, ascorbic acid content, SS and AT ratio and lycopene content were measured. The fruit thinning increased marketable yield, average weight, length and width for the Santa Cruz hybrids THX-02 and THX-03 and for THX-04, THX-05 and Netuno, classified as Italian type. The fruit thinning did not provide benefits for yield and its components for the other evaluated characteristics and genotypes. Giuliana and Sahel genotypes presented higher marketable yield and average fruit weight. Without fruit thinning, 'Netuno' reached the highest number of fruits per plant, but the hybrid Sahel showed higher marketable yield and average fruit weight. Thinning did not affect the organoleptic quality of the genotypes. 'Avalon' showed higher ascorbic acid content than 'Netuno' and 'Sahel', and 'Débora Max', 'THX-01

Prah je deponovan sa plazma pištoljem F4 na odstojanju substrata od 340 mm. Glavni cilj rada bio je da se na smanjenom pritisku inertnog gasa Ar eliminiše razgradnja primarnog karbida Cr3C2 u karbid Cr23C6 koji bitno umanjuje mikrotvrdoću i mehaničke karakteristike prevlake. Prevlaka je deponovana debljine od 100 do 120 µm na čeličnom substratu. Mikrotvrdoća prevlake ispitana je metodom HV0.3. Vrednosti mikrotvrdoće bile su u rasponu od 1248 do 1342 HV0.3. Čvrstoća spoja prevlake ispitana je metodom na zatezanje. Utvrđeno je da čvrstoća spoja između substrata i prevlake ima vrednost 89 MPa. Mikrostruktura prevlake ispitana je tehnikom svetlosne mikroskopije. Struktura prevlake sastoji se od osnove NiCr legure sa dominantnom primarnom karbidnom fazom Cr3C2. Pored Cr3C2 faze prisutna je i faza Cr7C3. Nagrizanje prevlake urađeno je reagensom 1HNO3: 4HCl: 4H2O koji prvenstveno rastvara Ni da bi se videla raspodela karbidne faze u prevlaci. Nagrizanjem prevlake reagensom utvrđeno je da je u slojevima prevlake u velikom udelu prisutna primarna nerazgrađena karbidna faza Cr3C2 koja prevlaci daje visoke vrednosti mikrotvrdoće. / This paper analyzes vacuum plasma spray VPS - Cr3C2 - 25(Ni20Cr coatings. Commercial powder marked Sulzer Metco Woka 7205 is used. The powder is deposited with a plasma gun F4 at a distance of 340 mm from the substrate. The main objective of the study was to eliminate, at the reduced pressure of inert gas Ar, the degradation of primary Cr3C2 carbide into Cr23C6 carbide which significantly reduces the microhardness and mechanical properties of the coating. The coating is deposited with a thickness of 100 - 120 µm on a steel substrate. The microhardness of the coating was tested by HV0.3. The microhardness values were in the range of 1248 - 1342 HV0.3.

    The semi enclosed Adriatic Sea is a sub basin of the Mediterranean Sea located in its northeastern part; it has a shallow northern part (average depth of 40 m) and a deep Southern Adriatic Pit (SAP) that reaches 1200m. The presence of a wide continental shelf exposed to strong heat and momentum fluxes during winter months makes the Northern Adriatic a formation site of dense waters, generally referred to as Northern Adriatic Dense Water (NAdDW). Once produced, it moves south as a quasi-geostrophically adjusted vein , flowing along the Italian coast and enters the SAP giving origin to descent and cascading dense shelf water bringing into the deep layers oxygen, nutrients and organic compound. In February 2012 a long and intense cold air outbreak, with strong Bora winds, interested the northern part of the Adriatic sea causing a drop in water temperature to less than 6 °C and an increase in density to values as high as 1030.2 kg/m3 (likely the maximum values since 1929). This resulted in a massive production of NAdDW. In order to study the behavior of the NAdDW vein, a rapid response 2 legs cruise (ODW2012) was organized in the southern Adriatic. During the cruise, along with physical and chemical measurements, water and phytoplankton samples were collected at different depths. Usual abundance and distribution with a general decrease in phytoplankton abundance from the surface to the bottom were found in all stations with one exception. The bottom sample of a station located roughly 40 km at 120 m depth in front of Gargano showed a significantly high dominance (40%) of the small diatom Skeletonema sp whose flowering is typical in the surface waters of the northern Adriatic in late winter. The physical parameters of the water column showed signs of the passage of the dense water vein (lower temperature and higher dissolved oxygen concentrations) hence it was hypothesized that those diatoms were actively transported by the NAdDW near-bottom stream.

    Full Text Available The intense cultivation of the melons in greenhouses has caused the rise of serious problems involved with soil pathogens, making it necessary to use grafting as an alternative in crop management in this environment. The objective of the present study was to determine the ideal morphophysiological stage of melon plants ‘Bonus No. 2’ for grafting by the closed cleft method, utilizing as rootstock the pumpkin hybrid ‘Shelper’, and to see if it affects take rate and productivity and quality of the fruits. A completely randomized block design was used with five treatments and five repetitions, where each plot comprised eight plants. The treatments consisted of four different stages of development of the seedlings of net melon (scion: developed cotyledonary leaves; first leaf in development; second leaf in development; and two developed leaves. Non-grafted plants served as the control. The non-grafted plants showed better values for rind netting, rind thickness and soluble solids. When compared to the graft treatments, there was no significant difference regarding the characteristics evaluated. If there is a need for grafting because of soil pathogens and salinity, the utilization of scions with the first leaf in development is recommended since they show better values for rind yield and soluble solids at an early morphophysiological stage. O cultivo intensivo do meloeiro em ambiente protegido tem causado o surgimento de sérios problemas relacionados à patógenos de solo, tornando necessário o emprego da enxertia como alternativa de manejo nesse ambiente. O objetivo com o presente trabalho foi a determinação do estádio morfofisiológico do meloeiro ‘Bônus n° 2’ ideal para a realização da enxertia pelo método da fenda cheia utilizando como porta-enxerto o hibrido de abóbora ‘Shelper’, e sua influência sobre o pegamento, produtividade e qualidade dos frutos.

    Full Text Available Diversos episódios e evoluções recentes mostram a adesão de setores tradicionais e novos das elites brasileiras ao predomínio das finanças e de suas razões na sociedade brasileira. A partir da análise do engendramento e da difusão da governança corporativa e dos fundos de private equities na acepção que elas vêm ganhando no Brasil, podemos mesmo falar de convergência das elites em torno dos mecanismos criados para a medição financeira, ainda que o resultado ocorra por meio de um alargamento de sua polissemia. Esses mecanismos, para cá trazidos no intuito explícito de acelerar e facilitar a integração das empresas brasileiras ao espaço e à lógica que impera nos mercados financeiros, avançam rapidamente, mas acabam recebendo um significado menos hardcore do que os financistas esperam. Ainda que deploráveis para os financistas ortodoxos, esses resultados dificilmente surpreenderiam um cientista social treinado. É por intermédio da polissemia que as abóboras se ajeitam na carroça da sociedade em movimento. A análise desse diálogo social produzido em torno das questões financeiras se torna assim uma excelente janela para a compreensão não só das disputas econômicas, mas também das disputas políticas que sacodem a sociedade brasileira contemporânea.Various recent episodes and evolutions demonstrate how both traditional and new sectors of the Brazilian elite have embraced the dominance of finance and its logic in Brazilian society. An analysis of the creation and diffusion of corporate governance and private equity funds - in the sense these have acquired in Brazil - allows us to identify a convergence of the country's elite sectors in terms of the mechanisms created for financial measurement, although this outcome stems from a broadening of their polysemy.

    Full Text Available A tomaticultura de mesa vem se modernizando nos últimos anos, com a implantação de unidades de beneficiamento e classificação que limpam, selecionam e classificam os produtos. Apesar destas mudanças, as perdas pós-colheitas ainda são altas, principalmente pela incidência de danos físicos, que ocorrem em pontos de transferência nos equipamentos e durante o processo de embalagem. Este trabalho teve como objetivo avaliar a qualidade dos frutos de tomate de mesa, cv "Débora", quando submetidos à queda após a etapa de limpeza em protótipo desenvolvido em laboratório para simular este sistema, relacionando alterações na qualidade com a magnitude de impacto encontrada (G, m/s2. Para tanto tomates foram beneficiados em rotações de 100 rpm e submetidos à queda em três diferentes alturas (10, 20 e 30 cm e três diferentes superfícies receptoras (espuma, caixa plástica e metálica. A magnitude dos impactos (G, m/s2 foi mensurada através da utilização da esfera instrumentada de 70 mm (Techmark, Inc., Lansing, EUA. A qualidade dos frutos após serem submetidos ao impacto foi avaliada por meio da perda de massa (%, injúria interna e de análises químicas. Os resultados obtidos com a esfera instrumentada mostraram que a superfície de espuma reduziu a aceleração máxima (G, m/s2 em aproximadamente 70%, para as alturas de queda de 10 e 20 cm e de 47% para a queda de 30 cm, quando comparada à superfície metálica. Nos ensaios com os tomates, observou-se que frutos submetidos à queda de 30 cm em superfície metálica apresentaram um aumento de 31% nos danos internos quando comparados aos frutos submetidos à queda desta mesma altura em superfície de espuma. A perda de massa foi maior (3,46% nos frutos submetidos à queda de 30 cm na superfície caixa plástica. Para as análises químicas não foi observada diferença estatística entre as três superfícies receptoras e as três alturas de queda. Por meio dos resultados obtidos

    connections in the nervous system, these synaptic transistors can mimic synaptic stimulation response and short-term synaptic plasticity. The idea of harnessing paper electronics for display applications seems a natural update on the familiar traditional uses of paper to host text and images. Jong-Man Kim and Bora Yoon at Hanyang University in Korea screen print a flexible paper-based display for representing the digits 0-9 [5]. The device exploits the electrochromothermic properties of five different polydiacetylenes to allow a range of activation temperatures and operational voltages for the display. A number of other applications also feature in the special issue, including two different supramolecular recognition architectures for DNA hybridization in sensing applications [6] and all-solid flexible micro-supercapacitors with excellent cycling stability [7]. The demonstrated potential in the alternative energy industry seems particularly fitting given the environmental recommendations of paper electronics. Despite the promising outlook demonstrated for fabricating on paper by screen or ink-jet printing, as Henrik A Andersson and colleagues point out, it may be some time before devices can be printed with the functionality of even the most inexpensive microcontroller or other integrated circuit [8]. In their report they consider different methods to mount and contact standard surface mount device components to ink-jet printed conductive tracks on paper substrates. 'If paper is used as a substrate for printed hybrid electronics, it opens the possibility of integrating low-cost electronic functions directly on packages, even possibly directly in the production line', they add. A blank sheet of paper can be considered useful for making notes, convenient for slipping in a purse or pocket and enormously inspiring for the infinity of ideas not yet written on it. As this special issue demonstrates [2-14] all three attributes are at least as valid when using paper for electronics

Além disso, atraíram imigrantes dos países vizinhos e de outras regiões do país em busca de trabalho ou de oportunidades de enriquecimento, o que garantiu a subsistência dessas cidades e conferiu a região um traço cultural característico. Essa capacidade relacional, desenvolvida de forma tácita através da atuação de agentes nas escalas sub-nacional e supranacional, contribuiu para diferenciar o subespaço Tabatinga-Letícia de seu entorno imediato. O conhecimento das inúmeras transações formais e informais realizadas entre as cidades de fronteira poderá incrementar a cooperação transfronteiriça e gerar alternativas econômicas para esses espaços que tem sido constantemente utilizados por redes de tráfico de drogas e contrabando.
