Nuclear tracks in the Angra dos Reis and Moore County meteorites

International Nuclear Information System (INIS)

Carver, E.A.; Anders, E.

1976-01-01

Charged particle tracks were studied in the Angra dos Reis and Moore County meteorites, both of which contain an unexplained excess of He 4 . A selective annealing method was used to resolve cosmic-ray tracks from fission tracks. It gave the following cosmic-ray and fission-track densities, in units of 10 6 cm -2 : Angra dos Reis 1.3 to 4.4 and 7.8; Moore Co. feldspar 1.9 to 3.0 and 0.51; Moore Co. pigeonite 2.0 to 2.9 and 0.078 to 0.35. The fission-track densities are 10 to 100 times higher than expected from U 238 ; the excess is probably due to extinct Pu 244 . The Pu 244 /U 238 ratios at the start of track retention were 0.003 for Angra dos Reis and 0.002 to 0.03 got Moore Co. No evidence was found for fission tracks attributable to the unknown progenitor of excess He 4 in these meteorites; the fission branch of this progenitor comprises less than 10 -5 the α-branch. A search for pleochroic halos also gave negative results. The preatmospheric radii of the two meteorites are >= 13 and >= 7 cm. According to meteor theory, this implies geocentric velocities of >19 and >= 6 km/sec. The etching behaviour of Angra dos Reis augite is highly anomalous, giving rise to spurious angular anisotropies and skewed length distributions. This confirms similar observation by Fleischer et al (Proc. Apollo II Lunar Sci. Conf. Geochem. Cosmochim. Acta Suppl.; 1:2103 (1970)) on lunar augite. (author)

Norton, M.I.; Frost, J.H.; Ariely, D.

2011-01-01

Reis, Maniaci, Caprariello, Eastwick, and Finkel (2011) conducted 2 studies that demonstrate that in certain cases, familiarity can lead to liking-in seeming contrast to the results of our earlier article (Norton, Frost, & Ariely, 2007). We believe that Reis et al.

Ge Hu; Qing She; Lei Guo

2012-01-01

In this paper, we synthesize three Re(I) complexes of Re(CO) 3 (PPO)Br, Re(CO) 3 (PTO)Br, and Re(CO) 3 (PBI)Br, where PPO=2-phenyl-5-(pyridin-2-yl)-1,3,4-oxadiazole, PTO=2-(pyridin-2-yl)-5-p-tolyl-1,3,4-oxadiazole, PBI=2-(pyridin-2-yl)-1H-benzo[d]imidazole. Their single crystals and photophysical properties are measured and discussed in detail. The correlation between ligand structure and corresponding PL characteristics of Re(I) complex has been investigated. It is found that a ligand with strong electron-donor can efficiently increase both absorption and emissive energy of Re(I) complex. In addition, electron-rich ligand can increase the electron density of the complex and thus enhance the oscillator strength of electronic transition, improving the photoluminescence performance. - Highlights: ► Three novel phosphorescent Re(I) complexes are synthesized. ► Molecular structures, photophysical, and electronic properties are studied. ► Strong electron-donor can increase emissive energy. ► Electron-rich ligand can enhance the oscillator strength of electronic transition.

Granular corneal dystrophy Groenouw type I (GrI) and Reis-Bücklers' corneal dystrophy (R-B). One entity?

Science.gov (United States)

Møller, H U

1989-12-01

This paper maintains that Reis-Bücklers' corneal dystrophy and granular corneal dystrophy Groenouw type I are one and the same disease. Included are some of the technically best photographs of Reis-Bücklers' dystrophy found in the literature, and these are compared with photographs from patients with granular corneal dystrophy examined by the author. It is argued that most of the histological and ultrastructural findings on Reis Bücklers' dystrophy described in the literature are either congruent with what is found in granular corneal dystrophy or unspecific.

Study of the dispersion of radionuclides in the Ilha Grande Bay - RJ

International Nuclear Information System (INIS)

Gomes, Franciane Martins de Carvalho

2010-01-01

The present work aimed the study of the dispersion profiles of radionuclides released in liquid radioactive effluents from the Central Nuclear Almirante Alvaro Alberto (CNAAA), in the Ilha Grande Bay, located in Angra dos Reis, RJ. Taking the overall activity released by liquid effluents discharge from the CNAAA in the Piraquara de Fora Bay as a reference parameter to the dilution rates scanning, the accordance level between the achieved 3 H results (1 :16) and those reported by Franklin (1 :20) can be seen as relevant. The post-1965 137 Cs concentration raise can be regarded as a consequence of the operational start up in the CNAAA, being the Ribeira Bay considered its preferential uptake, from the plume displacement high tide, as well as its retention, due to local deposition favourable trends. The evaluation of the prevailing mechanism on long half-life radio isotopes dispersion pointed out its dependence on meteorological condition parameters, during the sampling procedures. If diffusion prevailingness occurs, both 223 Ra and 224 Ra distribution pathways result in diffusion coefficients ranging from 20,12 ± 3,81 - 21,07 ± 3,91 km 2 .d -1 to a 228 Ra offshore flux and time of residence of, respectively, 3,18 ± 1,01 x 108 Bq.d-1 and 25,35 ± 0,45 days. On the other hand, an uppermost advection process provided 228 Ra offshore flux and time of residence of, respectively, 2,26 ± 0,424 x 10 8 Bq.d -1 and 13,08 ± 0,21 days. (author)

Extreme-value limit of the convolution of exponential and multivariate normal distributions: Link to the Hüsler–Reiß distribution

KAUST Repository

Krupskii, Pavel

2017-11-02

The multivariate Hüsler–Reiß copula is obtained as a direct extreme-value limit from the convolution of a multivariate normal random vector and an exponential random variable multiplied by a vector of constants. It is shown how the set of Hüsler–Reiß parameters can be mapped to the parameters of this convolution model. Assuming there are no singular components in the Hüsler–Reiß copula, the convolution model leads to exact and approximate simulation methods. An application of simulation is to check if the Hüsler–Reiß copula with different parsimonious dependence structures provides adequate fit to some data consisting of multivariate extremes.

PCR-based karyotyping of Anopheles gambiae inversion 2Rj identifies the BAMAKO chromosomal form

Directory of Open Access Journals (Sweden)

Conway David J

2007-10-01

Full Text Available Abstract Background The malaria vector Anopheles gambiae is polymorphic for chromosomal inversions on the right arm of chromosome 2 that segregate nonrandomly between assortatively mating populations in West Africa. One such inversion, 2Rj, is associated with the BAMAKO chromosomal form endemic to southern Mali and northern Guinea Conakry near the Niger River. Although it exploits a unique ecology and both molecular and chromosomal data suggest reduced gene flow between BAMAKO and other A. gambiae populations, no molecular markers exist to identify this form. Methods To facilitate study of the BAMAKO form, a PCR assay for molecular karyotyping of 2Rj was developed based on sequences at the breakpoint junctions. The assay was extensively validated using more than 700 field specimens whose karyotypes were determined in parallel by cytogenetic and molecular methods. As inversion 2Rj also occurs in SAVANNA populations outside the geographic range of BAMAKO, samples were tested from Senegal, Cameroon and western Guinea Conakry as well as from Mali. Results In southern Mali, where 2Rj polymorphism in SAVANNA populations was very low and most of the 2Rj homozygotes were found in BAMAKO karyotypes, the molecular and cytogenetic methods were almost perfectly congruent. Elsewhere agreement between the methods was much poorer, as the molecular assay frequently misclassified 2Rj heterozygotes as 2R+j standard homozygotes. Conclusion Molecular karyotyping of 2Rj is robust and accurate on 2R+j standard and 2Rj inverted homozygotes. Therefore, the proposed approach overcomes the lack of a rapid tool for identifying the BAMAKO form across developmental stages and sexes, and opens new perspectives for the study of BAMAKO ecology and behaviour. On the other hand, the method should not be applied for molecular karyotyping of j-carriers within the SAVANNA chromosomal form.

2016-01-01

The Hadron Physics series of workshops, which started in 1988, take place every two or three years. They have the format of an advanced school, consisting of didactic courses, thematic seminars and the presentation of posters on frontier topics in the physics of strong interactions. It is characterized by the active participation of graduate students and postdocs, and also promotes collaboration between reserach groups in Latin America and others distributed worldwide. The XIII International Workshop on Hadron Physics - XIII Hadron Physics - was held from 22-27 March 2015, in Hotel do Bosque, Mambucaba, near the city of Angra dos Reis, Rio de Janeiro state. With good weather, a beach and splendid natural beauty, the surroundings offered all the conditions for a fruitful and pleasant meeting. The scientific program of the XIII Hadron Physics workshop was composed of courses, seminars and contributed papers. The courses consisted of four sets of lectures of three hours each, which are all reproduced in the present volume, thanks to the kind efforts of the lecturers, for the use and appreciation of a wider public. These courses provided a pedagogical and updated account of recent developments that gave support to the discussion of frontier problems in the physics of strong interactions. Organizers and participants are aware that the lecturers bore primary responsibility for the success of the workshop and are especially grateful to them. The seminars reviewed recent developments in theory, computational techniques and experimentations investigating QCD in nonperturbative and high density regimes. Most of these seminars are reproduced in this volume. The Organizing Committee is thankful to the invited speakers for the quality of the presentations, which contributed to the success of the workshop. The contributed papers, mainly representing the scientific activity of young physicists, were exhibited as posters all throughout the event in the breakout area, and are also

Eukaryotic ribosome biogenesis depends on several hundred assembly factors to produce functional 40S and 60S ribosomal subunits. The final phase of 60S subunit biogenesis is cytoplasmic maturation, which includes the proofreading of functional centers of the 60S subunit and the release of several ribosome biogenesis factors. We report the cryo-electron microscopy (cryo-EM) structure of the yeast 60S subunit in complex with the biogenesis factors Rei1, Arx1, and Alb1 at 3.4 Å resolution. In addition to the network of interactions formed by Alb1, the structure reveals a mechanism for ensuring the integrity of the ribosomal polypeptide exit tunnel. Arx1 probes the entire set of inner-ring proteins surrounding the tunnel exit, and the C terminus of Rei1 is deeply inserted into the ribosomal tunnel, where it forms specific contacts along almost its entire length. We provide genetic and biochemical evidence that failure to insert the C terminus of Rei1 precludes subsequent steps of 60S maturation. Copyright © 2016 Elsevier Inc. All rights reserved.

This work was conducted in the city of Campos dos Goytacazes/RJ, in which four residual soils collected in the region were technologically characterized. We sought to determine their properties, such as analysis of the colors after firing, aiming at its use in ceramic art. To this end the tests were conducted in the laboratories of the Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF) and that are granulometry (by sieving and sedimentation), specific mass of grains, chemical analysis by X-ray fluorescence, diffraction mineralogical identification X-ray, differential thermal analysis and thermogravimetry. The soils were analyzed before drying at 110 deg C and after burning the different temperatures (500 deg C 750 deg C and 950 deg C). The analyzed results showed the physical composition, chemical and mineralogical of raw material. After burning was possible to observe several color variations. (author)

Full Text Available Reis Lake is located in the municipality of Caracaraí, state of Roraima (Brazil and is subject to fluctuations in water level. The aim of this study was to analyze the structure of the phytoplankton community on the nictemeral and seasonal scales and determined the influence of limnological variables. Sampling was performed in the rainy season (June/2006 and dry season (November/2006, considering two nictemeral cycles. The phytoplankton community was assessed with regard to composition and density, abiotic variables were analyzed simultaneously. The lake had low concentrations of oxygen, clinograde profile and water stratified during the day and homogenous at night, with low concentrations of nutrients and waters ranging from slightly acidic to alkaline. The phytoplankton was represented by 43 taxa, 35 species in the dry season and 29 species in the rainy season. Low densities of phytoplankton occurred in both nictemeral cycles, with accentuated vertical gradient. The highest densities were recorded in the dry season. Reis Lake exhibits characteristics that classify it as a polymythic and oligotrophic environment. The variability in the data was more important seasonally than on the nictemeral scale, supporting the hypothesis of the influence of the hydrological cycle on the dynamics of phytoplankton communities in floodplain lakes.O lago dos Reis está localizado no município de Caracaraí, no estado de Roraima (Brasil e está sujeito a flutuações no nível da água.

As amostragens foram realizadas nos periodos chuvoso e seco, considerando dois ciclos nictemeral. A comunidade fitoplanctônica foi avaliada no que diz respeito à composição e densidade, simultaneamente, variáveis abióticas foram analisadas. O lago apresentou baixas concentrações de oxig

Comparative analysis of three atmospheric dispersion coefficient systems at the Angra dos Reis, RJ, region

Biagio, Rosa Maria de Souza

1982-01-01

A comparative analysis was made in this work among Pasquill-Gifford (PG) atmospheric dispersion coefficients and those determined at the Juelich and Karlsruhe sites with the purpose of suggesting which one would be the most applicable to the Angra site. Each one of the three systems was determined by different experiments, carried out over sites with diversified features. The systems of Juelich and Karlsruhe were obtained over sites with high surface roughness and from stacks (elevated releases), while the PG system was obtained over sites with a small surface roughness and from ground level releases. The results of the application of these systems at a complex site like Angra,which has a highly diversified structure encompassing sea, vegetation, predominance of light winds and stable stability classes, show that the PG system, the most used in the world, is still the best choice.

A new resonance-frequency based electronic impedance spectroscopy (REIS) system with multi-probes, including one central probe and six external probes that are designed to contact the breast skin in a circular form with a radius of 60 millimeters to the central ("nipple") probe, has been assembled and installed in our breast imaging facility. We are conducting a prospective clinical study to test the performance of this REIS system in identifying younger women (detection of a highly suspicious breast lesion and 50 were determined negative during mammography screening. REIS output signal sweeps that we used to compute an initial feature included both amplitude and phase information representing differences between corresponding (matched) EIS signal values acquired from the left and right breasts. A genetic algorithm was applied to reduce the feature set and optimize a support vector machine (SVM) to classify the REIS examinations into "biopsy recommended" and "non-biopsy" recommended groups. Using the leave-one-case-out testing method, the classification performance as measured by the area under the receiver operating characteristic (ROC) curve was 0.816 +/- 0.042. This pilot analysis suggests that the new multi-probe-based REIS system could potentially be used as a risk stratification tool to identify pre-screened young women who are at higher risk of having or developing breast cancer.

The mineral contents in the samples were determined by atomic absorption spectrophotometry and values obtained were compared with clinical signs found. Low values of P and Na were confirmed and although the lack of Ca and Mg is uncommon, some samples showed low rates. We found high values of Fe with possible interference in the absorption of Cu, the main clinical deficiency identified in the region, and high values of Al, Zn and Mn. The results indicate that most mineral deficiencies diagnosed in those herds is due to antagonistic effects of minerals that are not deficient.

A preliminary evaluation was done of the potential environmental consequences derived from the emission from the condenser cooling of the nuclear power plants at the Angra dos Reis site. The calculation of the temperature field starting from the point of emission of the coolant discharge was done using the model of Stolzenbach for three dimensional heated surface discharge. Considerations were made of the potential environmental damage to the marine life based on the calculated temperature increase. Special atention was given to the potential damage to the necton's life, by estimating the probability of occurance of higher than lethal temperature for the known species living at the site. These species were given in the Safety Analysis Report of the Unity I of the nuclear station. (Author) [pt

Fassaitic pyroxene from the Angra dos Reis meteorite has striking spectral properties. The /sup 57/Fe Moessbauer spectra show no Fe/sup 3 +/, and thus the absorption is thought to originate from a complex charge-transfer process. Intense absorption at 480 nm dominates the spectrum of the meteorite and may be important in the interpretation of telescope spectra of objects in space.

The release of {sup 137}Cs and {sup 60}Co in the liquid effluents from the Angra dos Reis power plants could radiologically impact the Saco de Piraquara de Fora (SPF) inlet. The mobility and trend of the radionuclides in the water-sediment compartment were investigated by studies of thermodynamic and sorption-desorption. The values of distribution coefficients (Kd) were around 500 L. kg{sup -1} for {sup 60}Co and 400 L. kg{sup -1} for {sup 137}Cs that are lower than the literature values. The predominance of kaolinite in the clay fraction may have played a major role in the low observed Kd values. For both radionuclides, the sorption was higher for the sediment with higher cation exchange capacity, and the equilibrium conditions were reached only after the third day. Despite the relatively low Kd values and low sorption rates, both can considerably be accumulated in sediments, and the sorption reactions are partially irreversible. {sup 60}Co and {sup 137}Cs accumulate in orders of magnitude of 1010 and 109 Bq g{sup -1} sediment, respectively, which shows the ability of the sediments to remove and retain much of the {sup 137}Cs and {sup 60}Co released by the power plants. Considering the range of temperature of the SPF water, both sorption and desorption of the two metals increase with temperature. However, in general, the retention rates of the radionuclides in sediments remain constant. The sorption sites are heterogeneous since the sorption data can be adjusted by the Langmuir and Freündlich isotherms. The sorption of Co and Cs are endothermic processes, which are spontaneous at low temperature. (author)

A comparative analysis was made in this work among Pasquill-Gifford (PG) atmospheric dispersion coefficients and those determined at the Juelich and Karlsruhe sites with the purpose of suggesting which one would be the most applicable to the Angra site. Each one of the three systems was determined by different experiments, carried out over sites with diversified features. The systems of Juelich and Karlsruhe were obtained over sites with high surface roughness and from stacks (elevated releases), while the PG system was obtained over sites with a small surface roughness and from ground level releases. The results of the application of these systems at a complex site like Angra,which has a highly diversified structure encompassing sea, vegetation, predominance of light winds and stable stability classes, show that the PG system, the most used in the world, is still the best choice.

Does familiarity breed contempt or liking? Comment on Reis, Maniaci, Caprariello, Eastwick, and Finkel (2011).

2011-09-01

Reis, Maniaci, Caprariello, Eastwick, and Finkel (see record 2011-04644-001) conducted 2 studies that demonstrate that in certain cases, familiarity can lead to liking--in seeming contrast to the results of our earlier article (see record 2006-23056-008). We believe that Reis et al. (a) utilized paradigms far removed from spontaneous, everyday social interactions that were particularly likely to demonstrate a positive link between familiarity and liking and (b) failed to include and incorporate other sources of data-both academic and real-world-showing that familiarity breeds contempt. We call for further research exploring when and why familiarity is likely to lead to contempt or liking, and we suggest several factors that are likely to inform this debate.

Anthropogenic impact on the sedimentation in coastal regions: an example in Saco do Bracui - Ribeira Bay, Angra dos Reis, Brazil

International Nuclear Information System (INIS)

Barbosa, Alayde Alfaia

2001-01-01

The Saco do Bracui, located in the littoral zone of the Brazilian southeast, receives run off from the region of Angra dos Reis. Anthropological intervention in this area has modified local morphology during the last 40 years. These modifications include an intense deforestation of mangrove regions, construction of the Bracui Boat Yard, the dredging of part of the draining basin and development of the coastal plain. Results from seismic surveys identify three different stratigraphic units separated by two reflectors as well as Holocenic paleodeltas and paleochannels of the Bracui and Gratau rivers. Results from this study and previous work indicate an age of 6800 years for the top of the superior unit. Areal photographs from the years 1964, 1965, 1978 and 1991 reveal the principal modifications occurring during the last 40 years in the area. Field observations from this study as well as bathymetric profiles based on the nautical maps of 1980 and 1944 reveal shoaling and erosion areas in the Saco do Bracui. Sedimentation rates, using lead-210 profiles, are between 0,17 - 1,90 cm/year and lead-210 inventory values are between 16-6-dpm/cm 2 /year. The results for sedimentation rate and inventory show a high accumulation around Bracui, Gratau and Frade mouth rivers and agree with results from the bathymetric profiles with respect to the site of erosion and shoaling in the Saco do Bracui. The results for grain size and lead-210 analyses support the idea that the Saco do Bracui is suffering shoaling processes in specific sites and erosion in others. Comparison between long term sedimentation rates obtained by seismic results and short term rates obtained by lead-210 shows an increase of the sedimentary discharge in the 1960's, when the intense anthropological intervention in the area began.

In order to respond to a major radiological emergency at the Almirante Alvaro Alberto Nuclear Power Plant, located in Angra dos Reis, Rio de Janeiro, the Emergency Response Team of the Institute for Radiation Protection and Dosimetry (IRD/CNEN) established a program of environmental monitoring. The purpose of this program is to define a monitoring trend to assess the off-site radiological conditions and give support to decision making for implementing protective measures in case of a radiological accident, taking into account atmospheric diffusion, population conglomerates and their habits, water and land use, contemplating the entire Emergency Planning Zone of 15 km radius. This program has been reevaluated recently, aiming to optimize it and keep it up to date to assure adequacy of environmental surveillance data in support to a prompt response in case of an emergency situation in the nuclear power plant. It has been organized in the form of a handbook to facilitate handling by field teams. Future revisions will be necessary to incorporate additional pertinent information and keep the handbook up to date, since Angra dos Reis is a summer resort region, subject to constant changes. This paper discusses the structure of the environmental monitoring program and describes the content and preparation of this handbook. (author)

Durante seu auge, no século IX, a cidade foi governada por um rei chamado Kukulcán, que foi responsável pela maioria das construções arquitetônicas da cidade. Tal governo foi marcado por uma eficiente propaganda política que foi planejada segundo um processo cognitivo de representação imagética do governante, cuja principal manifestação deu-se em forma de uma serpente emplumada.

Concurrent validity of the Wheeler signs of homosexuality in the Rorschach: P (Ci/Rj).

Science.gov (United States)

Stone, N M; Schneider, R E

1975-12-01

The Rorschach protocols of 43 males consecutively admitted to a university outpatient clinic were scored for frequency of the 20 Wheeler signs of homosexuality. Based on case history data, patients were assigned to homosexual, sex-role disturbed, or normal-control groups. In addition to the traditional group comparison the results were analyzed to yield P (Ci/Rj); that is, the probability of criterion group membership given test indicator. Both the homosexual and sex-role disturbed group displayed significantly more Wheeler signs than normals. Furthermore, given a Wheeler sign score of 15%, .75 of the predicted-homosexual group would be correctly classified compared to a .21 baserate prediction. It was suggested that expressing results as P (Ci/Rj) provides information more relevant to the clinician than is provided by the traditional practice of reporting significant differences between groups.

Persistency of atmospheric diffusion conditions in Angra dos Reis - Brazil

International Nuclear Information System (INIS)

Nicolli, D.

1981-12-01

Based on a 2 year observation period, the diffusion conditions at the Almirante Alvaro Alberto N.P.P. site, in Angra dos Reis, are analized with respect to persistency as a function of the wind direction, the Pasquill stability class and the time of the day. The Pasquill stability class relates to the bulk vertical temperature gradient measured between 2m and 50m in the atmosphere; the wind direction is measured at 50m height. The persistency is defined in this report as the probability that the wind direction will remain longer than a given time in a sector without change in the diffusion category by more than a certain stage. During the day the persistency is mostly affected by the sea breeze with predominance of the unstable and neutral categories. At night the stable categories dominate. The alternating sea and land breezes disturb daily the trade wind field resulting in low persistency of the diffusion conditions. (Author) [pt

2015-10-29

The structural, electronic, and optical properties of the all-trans and five cis conformers of [Re(CO)3(bpy)(ret-pyr-CN)](+) (bpy = 2,2'-bipyridine; ret-pyr-CN = pyridyl-CN-3,7-dimethyl-9-(2,6,6-trimethylcyclohex-2-n)-none-(2,4,6,8-tetraen) were studied in solvent by means of density functional theory (DFT) and time-dependent DFT. The isolated retinal-like chromophore ret-pyr-CN was investigated as well for comparison. By coordination to the complex the two lowest intraligand (IL) states localized on the retinal group are slightly red-shifted from 627 to 690 nm and from 415 to 450 nm, respectively. Several isomerization pathways are open upon irradiation of the Re(I) complex by visible light (400-450 nm), especially to two cis conformers corresponding to the isomerization of the two double bonds of the retinal-like ligand close to the pyridyl group linked to the Re(I) fragment. The metal-to-ligand charge transfer states localized either on the retinal group or on the bpy ligand should play a minor role in the isomerization process itself but could improve its efficiency via ultra-fast intersystem crossing.

Olhos de inferno: a morte no Rei Édipo de Sófocles

Directory of Open Access Journals (Sweden)

Ortep J. Trindade-Serra

1995-12-01

Full Text Available Os derradeiros versos do "Rei Édipo", de Sófocles, versos que se referem a um tópos consagrado, ocasionaram, através de uma paráfrase de Frínico, a criação do "mito" de Sófocles, cuja vida feliz a tradição consagrou como uma antítese do destino de seu personagem. O paradoxo desses versos, todavia, merece consideração mais profunda. Com efeito, em toda a tragédia a morte é representada de maneira paradoxal. Édipo faz a experiência de uma situação liminar em que morte e vida, cegueira e visão se confundem. Uma evidência disso é simbolicamente dada no verso 987 de Oedipus Rex.

Full Text Available A circulação geostrófica e as condições hidrográficas, na borda da plataforma continental adjacente ao Cabo Frio (RJ, são analisadas ao longo de duas secções verticais realizadas em julho de 1968. A principal característica resultante dessa análise é a ocorrência de movimentos para leste e oeste, com velocidades estimadas atingindo valores de até ± 2 cm.s-1 e -49 cm.s-1, respectivamente. Os movimentos para leste apresentam um fluxo de volume de 0,52 Sv (0,40 Sv e as maiores velocidades são atingidas abaixo da picnoclina e na região adjacente a borda da plataforma continental. O principal movimento para oeste, tem as maiores velocidades na camada de superfície, e os pequenos valores do transporte de volume, de -2,24 Sv (-2,68 Sv, sugerem que as observações hidrográficas foram realizadas na região de cisalhamento ciclonico da Corrente do Brasil. Detalhes da distribuição do fluxo de volume são apresentados sobre o diagrama T-S, em correspondência com classes delimitadas por intervalos de variação da anomalia termostérica e da temperatura.The geostrophic circulation and the hydrographic conditions on the edge of the continental shelf off Cabo Frio (RJ were investigated along two vertical sections sampled on July 1968.

Full Text Available A ficotoxina ácido ocadaico (AO é produzida por um grupo de microalgas conhecidas como dinoflagelados. Os mexilhões, ao se alimentarem dessas microalgas, acumulam a toxina em sua glândula digestiva, desencadeando a Síndrome ou Envenenamento Diarreico por Moluscos (EDM no ser humano. Os sintomas se apresentam em torno de 30 minutos após o consumo do molusco contaminado, variando entre náuseas, dores abdominais, vômitos e diarreia. Quando a ingestão da toxina acontece em quantidades inferiores a 48µg g-1, os sintomas não se desenvolvem, porém seu consumo continuado favorece o surgimento de tumores no trato gastrointestinal em razão do poder carcinogênico do AO. Este estudo pretendeu detectar e quantificar a toxina diarreica AO em mexilhões Perna perna coletados entre os meses de maio e outubro de 2006. A detecção do AO nos mexilhões foi realizada por Cromatografia Líquida de Alta Eficiência com Detecção Fluorimétrica (CLAE-DF. Os resultados cromatográficos indicaram a presença da toxina AO em baixas concentrações, em todas as amostras de mexilhões obtidas de maio a outubro de 2006. Os resultados indicam a necessidade da elaboração e aplicação efetiva de um programa de controle higiênico-sanitário dos moluscos, assim como o monitoramento do ambiente aquático, objetivando, acima de tudo, a segurança da saúde pública.Okadaic acid (OA is a phycotoxin produced by a group of microalgae known as Dino-flagellates. When mussels feed themselves from this micro seaweed the toxin accumulates in their hepatopancreas, triggering the Syndrome or Diarrhetic Shellfish Poisoning (DSP in the human being. The symptoms appear around 30 minutes after the consumption of contaminated mussels and include abdominal nauseas, pains, vomits and diarrhea. When the toxin ingestion happens in amounts lower than 48µg g-1, the above described symptoms do not develop. However, the continued consumption favors the emergence of tumors in the gastrointestinal tract because of the high carcinogenic power of OA. This study aimed to detect and quantify the diarrheic toxin OA in Perna perna mussels collected between May and October 2006. The detection of OA in the mussels was carried out through High Performance Liquid Chromatography with Fluorimetric Detection (HPLC-FD. The chromatographic results indicate the presence of OA toxin in low concentrations in all the mussel samples gathered from May until October 2006. The results suggest the necessity of elaboration and effective application of a hygienic-sanitary mussel control program as well as environment monitoring, with the main aim of enhancing public health safety.

Gamma radiation in a set of rooms of the sector D of the Cardeal Leme Building in the Pontifica Universidade Catolica of Rio de Janeiro, and also in some outdoors ares at the PUC/RJ campus, are examined using well established experimental techniques. The exposures were obtained by using CaSO 4 :Dy thermoluminescent dosimeters and one NaI(Tl) crystal associated with a multichannel pulse height analyser to store the gamma ray spectra of the locations chosen for the measurements. Outdoors, the average of the actual readings of exposures rates obtained at PUC/RJ campus remained around 2,5x10 -2 mC/Kg.y (98 mR/year), while indoors the average exposure rates were in some cases three times higher than the equivalent average obtained outdoors. Some of potential causes to the fact that exposure to gamma radiation is, in general, higher indoors than outdoors are examined and discussed. (author) [pt

The improvement gap in energy intensity: Analysis of China's thirty provincial regions using the improved DEA (data envelopment analysis) model

International Nuclear Information System (INIS)

Li, Ke; Lin, Boqiang

2015-01-01

Enacting a reduction target for energy intensity in provinces has become an important issue for the central and local governments in China. But the energy intensity index has provided little information about energy efficiency improvement potential. This study re-estimates the TFEE (total-factor energy efficiency) using an improved DEA (data envelopment analysis) model, which combines the super-efficiency and sequential DEA models to avoid “discriminating power problem” and “technical regress”, and then used it to calculated the TEI (target for energy intensity). The REI (improvement potential in energy intensity) is calculated by the difference between TEI and the actual level of energy intensity. In application, we calculate the REIs for different provinces under the metafrontier and group-frontier respectively, and their ratios are the technology gaps for energy use. The main result shows that China's REIs fluctuate around 21%, 7.5% and 12% for Eastern, Central and Western China respectively; and Eastern China has the highest level of energy technology. These findings reveal that energy intensities of China's provinces do not converge to the optimal level. Therefore, the target of energy-saving policy for regions should be enhancing the energy efficiency of the inefficient ones, and thereby reduce the gap for improvement in energy intensity across regions. - Highlights: • We present an improved DEA model to calculate the TFEE (total-factor energy efficiency). • The improved TFEE combines with a meta-frontier analysis. • We estabilish a new indicator for improvement gap in energy intensity. • Improvement in energy intensity of regions in China is analysed

Magmatism and cenozoic tectonism in the Cabo Frio region, RJ, Brazil

International Nuclear Information System (INIS)

Mohriak, W.U.; Barros, A.Z.N. de; Fujita, A.

1990-01-01

The western portion of the Campos Basin is limited by a hinge line that bounds the deposition of pre-Aptian sediments in the offshore region. The Cabo Frio arch corresponds to a platform with smaller relative subsidence, where Tertiary sediments are deposited directly on shallow basement rocks. Towards the continental slope of the Cabo Frio region, tectonic activity is also observed in the post-Aptian sequence, particularly in the region between the Santos and Campos basins, where a very large graben trends parallel to the pre-Aptian limit of the basin, and is controlled by faults that-affect Upper Miocene rocks. Eastwards of this region, an array of antithetic faults trends in a NE direction. These faults, apparently detaching an the Aptian salt, show unique geometric patterns. The rupturing of Pangea in the Lower Cretaceous is marked by widespread outpouring of mafic magmas in Campos and Santos basins. Radiometric age determinations for this volcanism show a mean of about 139 M.a. After the rift phase, another volcanic episode is observed in the Cabo Frio region, with K/Ar radiometric dating of about 50 M.a. Volcanic mounds are observed within the Eocene sedimentary sequence. An Eocene volcanic episode is characterized by the presence of volcaniclassic rocks, including autoclastic, hydroclastic, epiclastic and pyroclastic sediments. This tectonic episode is also identified within other stratigraphic intervals in the sedimentary column. (author)

Watertightness in anti-flotation slabs: MIS-RJ case

C. Britez

Full Text Available It is common in coastal cities as Rio de Janeiro, that buildings located close to the shoreline have their basements below water table level. In most cases, the engineering solution for these buildings is to design a massive anti-flotation slab to satisfy, principally, the issues related to structural dimensioning and calculation hypothesis. On the other hand, the execution of this solution imply in significant construction problems related to reinforced concrete watertightness and durability. This paper presents a case study about challenges and solutions devised to execute an anti-flotation, 1m thick, 1200m³ reinforced concrete slab for the new Museu de Imagem e Som (MIS - Sound and Image Museum, located at 50m from the seashore, at Copacabana in Rio de Janeiro, RJ. The results show that concrete proportions, concreting plan and pouring method adopted were decisive in obtaining a watertight structure, avoiding thus the employment of traditional waterproofing alternatives.

Full Text Available Trinta e nove touros provenientes de propriedades de pecuária leiteira (n=9 e de pecuária de corte (n=30, situadas na região do Médio Paraíba, Rio de Janeiro (RJ, foram investigados para a presença de Campylobacter fetus e Tritrichomonas foetus. Para a pesquisa de Campylobacter, amostras de esmegma foram coletadas e submetidas à técnica de cultivo e isolamento e amostras de lavado prepucial ao teste de Imunofluorescência Direta (IFD. Para a pesquisa de Tritrichomonas, foi utilizada a técnica de exame direto a partir de lavado prepucial. Foi observada a presença de C. fetus em 14 amostras (35,9 %, por meio da IFD, e o isolamento de C. fetus, subespécie venerealis, foi obtido a partir de quatro amostras (10,3%. T. foetus não foi identificado nas amostras investigadas. A alta freqüência de C. fetus observada nos animais investigados sugere a presença da campilobacteriose na região do Médio Paraíba, em rebanhos com problemas reprodutivos.Thirty nine breeding bulls from dairy farms (n=9 and beef farms (n=30 located in Médio Paraíba region at Rio de Janeiro - Brazil state were investigated for the presence of Campylobacter fetus and Tritrichomonas foetus. For Campylobacter investigation, smegma samples were examined by culture and prepucial washings were examined by direct immunofluorescence technique (DIF. The prepucial washings were also examined for Tritrichomonas foetus presence by direct examination. C. fetus was identified in 14 samples (35.9 % by DIF technique and C. fetus subspecies venerealis was isolated from four samples (10.3%. T. foetus was not detected in bull samples. The high frequency of C. fetus observed in bull samples suggests the occurrence of Campylobacteriosis among herds which have reproductive problems at the Médio Paraíba region.

Full Text Available O artigo analisa aspectos econômicos da elite colonial mineira a partir de meados do século XVIII, mediante a investigação empírica da sociedade de São João Del Rei. O comércio em São João assumiu um papel central na liquidez da economia regional, permitindo a formação de grupos hegemônicos no século XIX. Mas há ainda muitas dúvidas sobre quem era essa elite no século XVIII. Com base em pesquisa prosopográfica que reconstrói os caminhos dos homens arrolados por Domingos Nunes Vieira como os mais ricos da capitania de Minas Gerais no ano de 1756, percebemos que a elite mineira que se formou no século XVIII diferia dos padrões mais gerais para a caracterização de grupos hegemônicos em outras regiões do Brasil, no mesmo período

Periods of high intensity rainfall and the safety of the Angra dos Reis nuclear power plant

International Nuclear Information System (INIS)

Nicolli, D.

1993-01-01

The high precipitation rates aggravate the consequences of hypothetical accidental releases of radioactive material from the Angra dos Reis Nuclear Power Plant (NPP), as determined by probabilistic risk assessment. A 30-year rainfall series was analysed, aiming at calculating the probability of occurring a given amount q of precipitation during a certain period of n days. The nine highest precipitation amounts have also been determined. The results show there was a rainier climate in the '50 s and '60 s than in the '70 s and '80 s. The risk of catastrophic landslide has been enhanced as an environmental impact of the construction of the Rio-Santos highway and NPP which have not yet gone through an abnormal rainfall period. It has been suggested that criteria should be established to reduce the nuclear power and shut down the reactor when the precipitation accumulates to a dangerous limit. (author)

Few data are available regarding viral hepatitis perception among the general global population. The present study aims to estimate the perception of viral hepatitis in a cohort of individuals living in two geographical regions of Brazil: North (Manaus city (MA)) and Southeast (Rio de Janeiro city (RJ)). A cross-sectional, descriptive study was carried out among 287 subjects recruited in MA (134) and RJ (153). All individuals answered a questionnaire assessing socio-demographic characteristics and viral hepatitis awareness. Participants’ responses were scored and divided using interquartile values. Associations between socio-demographic characteristics and knowledge were also evaluated. Interquartile analysis scored 0–21 correct answers as “Very Weak”; 22–27 as “Weak”; 28–31 as “Intermediate”; and 32–47 as “Desirable”. Mean ± standard deviations (SD) of correct responses were weak in both MA (24.1 ± 7.0) and RJ (26.3 ± 7.3). Bivariate analysis showed an association between viral hepatitis awareness and both education level (p < 0.001) and family income (p < 0.01). Desirable scores were more common in female participants (61%), those aged between 21–30 years (40%), those with a secondary education (51.7%), those who received high income (31.6%), and those from RJ (70.0%). Health education campaigns in these cities are recommended to increase knowledge and reduce the transmission of these viruses. PMID:29364166

Wind induced upwelling events are frequently observed in the area during summer, becoming rare during winter. By the summer cruise a bloom of phytoplankton was observed in surface, close to the coast, with chlorophyll concentrations reaching 25.55 mg Chl-a m-3, uncoupled from the cold, nutrient rich waters of South Atlantic Central Water (SACW, found below 40 m depth. During the winter cruise, the SACW raised at the surface waters in front of Cabo Frio depicting an upwelling event. However, in spite of high surface nitrate concentrations (up to 7.7 f.1M chlorophyll-a were lower than 2 mg Chl-a m-3. The phytoplankton biomass, meteorological and hydrological data suggest a probable upwelling event immediately before the summer cruise, and an ongoing one during winter time.

Full Text Available No Brasil atual, o turbulento contexto político, econômico e social tem sido terra fértil para o exame das práticas de gestão. Assim, o presente artigo tem por propósito investigar a realidade socioeconômica no município de Quissamã (RJ em conexão com a expansão dos recursos financeiros advindos do petróleo, que abasteceram os cofres públicos a partir de 1997. Para tanto, fez-se revisão bibliográfica e análise quantitativa de dados, fruto de pesquisa a documentos públicos da prefeitura. Nesta etapa, foram identificados os mecanismos de gestão e aplicação dos recursos originados no petróleo, como principais promotores do desenvolvimento local. Adicionalmente, foi estabelecida análise comparada entre Quissamã (RJ e o município vizinho Conceição de Macabu (RJ, visto que estes mantêm características territoriais e demográficas semelhantes. A despeito de Conceição não receber recursos do petróleo nos patamares de Quissamã, apresentou melhores índices de desenvolvimento. De resultado, verificou-se aumento da concentração de renda e a constatação de que os recursos públicos não geraram benefícios mais estruturantes para a população. Acredita-se que o debate proposto possa contribuir para o aperfeiçoamento das ações governamentais, restando salientar a necessidade de se aprofundar o que ora se discute, estabelecendo-se novos caminhos, num processo de melhoria da gestão de recursos públicos.

E-mail: jairopinheirodasilva@gmail.com Toxoplasma gondii is a protozoan parasite that infects up to a third of the world's population. Infection is mainly acquired by ingestion of food or water that is contaminated with oocysts shed by cats or by eating undercooked or raw meat containing tissue cysts and by blood transfusion or organ transplantation. Primary infection is usually subclinical but in some patients cervical lymphadenopathy or ocular disease can be present. Infection acquired during pregnancy may cause severe damage to the fetus. In immunocompromised patients, reactivation of latent disease can cause life-threatening encephalitis. Diagnosis of toxoplasmosis can be established by direct detection of the parasite or by serological techniques. The aim of the present study was verify the seroprevalence of toxoplasmosis in cornea donors of Rio de Janeiro, Brazil. IgM and IgG anti- T. gondii antibodies were investigated in 426 sera of corneal donors by using the indirect fluorescent antibody test (IFAT and immunoenzymatic assay (ELISA techniques.

This paper aimed to characterize the anatomical structure of the wood of specimens of Mollinedia glabra (Spreng.) Perkins growing in two contiguous formations of restinga vegetation at Praia Virgem, in the municipality of Rio das Ostras, RJ. Both the Open Palmae (OPS) and the Sandy Strip Closed Shrub (SSCS) formations are found in coastal regions that receive between 1,100 and 1,300 mm of rainfall per year. Sapwood samples were collected in both formations. Typical anatomical features for this species include: solitary vessels, radial multiples or clusters elements, that are circular to angular in outline, 5-15 barred scalariform perforation plates, wood parenchyma scanty, septate fiber-tracheids, and wide multiseriate rays with prismatic crystals. Statistical analyses indicated a significant increase in the frequency of vessel elements and an increase in fiber-tracheid diameters in OPS individuals. These characteristics are considered structural adaptations to increased water needs caused by a greater exposure to sunlight. Continuous pruning may be responsible for the tyloses observed in OPS plants. The greater lengths and higher frequencies of the rays in SSCS trees may be due to the greater diameters of their branches. Our results suggest that M. glabra develops structural adaptations to the restinga micro-environmental variations during its development.

Full Text Available This text analyses João Mário Grilo’s film: O Processo do Rei (The King’s Trial (1989. Based on the trial of Afonso VI, the director was able to remain faithful to the seventeenth century historical setting, but at the same time give it a contemporary feel, while exploring eternal and recurrent aspects of the story itself. Cinema, in this film, works as a stage where the story reveals the scenography that history books habitually conceal. In order to thoroughly examine the issues raised by this text, the article discusses the relationship between cinema and theatre starting with the concept of mise en scéne. What joins and separates these two artistic forms? How has cinema built its own mise en scéne throughout its history while resorting mostly to editing?En este texto analizaré la película O Processo do Rei (1989, de João Mário Grilo. Basado en el proceso contra D. Afonso VI, el realizador consiguió ser fiel al tiempo histórico –siglo XVII-, pero también profundamente contemporáneo, explorando aspectos eternos y cíclicos de la propia Historia. El cine, en esta película, funciona como un escenario donde la Historia revela la escenografía que los libros de Historia acostumbran a ocultar. Para profundizar en esta cuestión comienzo por discutir las relaciones entre el cine y el teatro a partir do concepto de mise en scéne. ¿Qué aproxima, y qué distancia, a estas dos formas artísticas? ¿De qué manera el cine, a lo largo de su historia, construyó su propia puesta en escena recurriendo, sobre todo, al montaje?

"And they told two friends...and so on": RJ Reynolds' viral marketing of Eclipse and its potential to mislead the public.

Science.gov (United States)

Anderson, S J; Ling, P M

2008-08-01

To explore viral marketing strategies for Eclipse cigarettes used by the RJ Reynolds Company (Winston-Salem, North Carolina, USA). Analysis of previously secret tobacco industry documents and multimedia materials. The failure of RJ Reynolds' (RJR) 1988 "smokeless" cigarette, Premier, was in part due to widespread bad word of mouth about the product's flavour, quality and difficulty of use. In 1994 RJR introduced an updated version of Premier, the ostensibly "reduced risk" Eclipse cigarette. RJR developed viral marketing channels to promote Eclipse using (1) exploratory interviews to motivate consumers to spread the word about Eclipse prior to market release, (2) promotional videos featuring positive feedback from test group participants to portray majority consensus among triers, (3) "Tupperware"-like parties for Eclipse where participants received samples to pass around in their social circles and (4) the Eclipse website's bulletin board as a forum for potential users to discuss the brand in their own words. These strategies targeted the brand's likeliest adopters, recruited informal and credible representatives of the product unaffiliated with RJR, and controlled the information spread about the product. Viral marketing techniques may be particularly useful to promote new tobacco products such as Eclipse that have limited appeal and need a highly motivated audience of early adopters and acceptors. Such techniques help evade the mass rejection that could follow mass promotion, circumvent marketing restrictions, and allow tobacco companies to benefit from health claims made by consumers. Cigarette manufacturers must be held accountable for perceived health benefits encouraged by all promotional activities including viral marketing.

This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models to simulation of tritium dispersion caused by an accident in a Candu reactor located in the ongoing Angra 3 site. The Candu reactor is one that uses heavy water (D 2 O) as moderator and coolant of the core. It was postulated, then, the LOCA accident (without fusion), where was lost 66 m3 of soda almost instantaneously. This inventory contained 35 P Bq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios (plant stopped or operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1 MBq/m 3 ) during the first 14 days after the accident.

Medijuotoji komunikacija vis labiau tampa dominuojančia socializacijos forma, ji išstumia gyvąją komunikaciją: kuo toliau, tuo labiau šis reiškinys nusako ne tik jaunimo, bet ir brandaus amžiaus žmonių šiandienį bendravimo būdą. Tad akivaizdu, kad XXI a. žmogus vis labiau pasineria į įvairių medijų tinklus, apraizgančius jo gyvenimą ir tampančius pagrindine socialios ir visavertės eg zistencijos sąlyga. Tokios socialinės institucijos, kaip menas, televizija, politika, religija, šeima ir daugelis kitų, nūdien jau nebėra tokios savarankiškos, kaip, tarkime, prieš dešimt, dvidešimt ar daugiau metų. Jų suverenitetą daugiausia transformuoja būtent medijos, šioms institucijoms diktuojančios savas sąlygas ir primetančios savas taisykles. Kitaip tariant, medijos tampa tokios galingos, kad ima steigti savuosius dėsnius, kuriems vis labiau paklūsta tradicinė gyvosios socializacijos aplinka. Taip kyla daugybė diskutuotinų ir ginčytinų klausimų, paliečiančių socialinių institucijų apibrėžties, autonomijos ir suvereniteto aspektus. Šiuos aspektus iš įvairių perspektyvų gvildena ir šio numerio autoriai.

Cities with production clusters have differentiated development in relation to other cities. This development has a direct influence on the location / installation and management of companies. This factor allows the organization gain a competitive advantage due to proximity to their suppliers and direct contact with the local population. With supplier companies increase the mobility of its supply chain and benefit from the existence of quality equipment in the network. This study aims to analyze, evaluate and classify the productive clusters of cities in the State of Rio de Janeiro, particularly in the municipalities of Angra dos Reis, Campos and Petropolis, to achieve balanced local development that benefits all stakeholders by product / city services. Productive clusters must necessarily contribute to improving the level of service offered to the customer. The methodology adopted was proposed by the Suzigan et al (2003 and Britto and Albuquerque (2002, to assess, analyze and classify the clusters in addition to bibliographic survey to support the study. The results show that depending on the importance of economic activity for the city, the production clusters greatly contribute to local development and increase the range of options for the local consumer.

On the 20th of March 2007 a large rock avalanche fell on Morsárjökull, one of the outlet glaciers from the southern part of the Vatnajökull ice cap, in south Iceland. This is considered to be one of the largest rock avalanches which have occurred in Iceland during the last decades. It is believed that it fell in two separate stages, the main part fell on the 20th of March and the second and smaller one, on the 17th of April 2007. The Morsárjökull outlet glacier is about 4 km long and surrounded by up to 1000 m high valley slopes. The outlet glacier is fed by two ice falls which are partly disconnected to the main ice cap of Vatnajökull, which indicates that the glacier is mainly fed by ice avalanches. The rock avalanche fell on the eastern side of the uppermost part of the Morsárjökull outlet glacier and covered about 1/5 of the glacier surface, an area of about 720,000 m2. The scar of the rock avalanche is located on the north face of the headwall above the uppermost part of the glacier. It is around 330 m high, reaching from about 620 m up to 950 m, showing that the main part of the slope collapsed. It is estimated that about 4 million m3 of rock debris fell on the glacier, or about 10 million tons. The accumulation lobe is up to 1.6 km long, reaching from 520 m a.s.l., to about 350 m a.s.l. Its width is from 125 m to 650 m, or on average 480 m. The total area which the lobe covers is around 720.000 m2 and its mean thickness 5.5 m. The surface of the lobe shows longitudinal ridges and grooves and narrow flow-like lobes, indicating that the debris mass evolved down glacier as a mixture of a slide and debris flow. The debris mass is coarse grained and boulder rich. Blocks over 5 to 8 m in diameter are common on the edges of the lobe up to 1.6 km from the source. No indication was observed of any deformation of the glacier surface under the debris mass. The first glaciological measurements of Morsárjökull outlet glacier were carried out in the year 1896

Once non-biodegradable, microplastics remain on the environment absorbing toxic hydrophobic compounds making them a risk to biodiversity when ingested or filtered by organisms and entering in the food chain. To evaluate the potential of the contamination by microplastics in mussels cultivated in Jurujuba Cove, Niterói, RJ, waters of three stations were collected during a rain and dry seasons using a plankton net and later filtered. Microplastics were quantified and characterized morphologically and chemically. The results showed a high concentration of microplastics in both seasons with diversity of colors, types and sizes. Synthetic polymers were present in all samples. The presence of microplastics was probably due to a high and constant load of effluent that this area receives and to the mussel farming activity that use many plastic materials. Areas with high concentrations of microplastics could not be used for mussel cultivation due to the risk of contamination to consumers. Copyright © 2016 Elsevier Ltd. All rights reserved.

“And they told two friends…and so on”: RJ Reynolds’ viral marketing of Eclipse and its potential to mislead the public

Anderson, S J; Ling, P M

Objective To explore viral marketing strategies for Eclipse cigarettes used by the RJ Reynolds Company (Winston-Salem, North Carolina, USA). Methods Analysis of previously secret tobacco industry documents and multimedia materials. Results The failure of RJ Reynolds’ (RJR) 1988 “smokeless” cigarette, Premier, was in part due to widespread bad word of mouth about the product’s flavour, quality and difficulty of use. In 1994 RJR introduced an updated version of Premier, the ostensibly “reduced risk” Eclipse cigarette. RJR developed viral marketing channels to promote Eclipse using (1) exploratory interviews to motivate consumers to spread the word about Eclipse prior to market release, (2) promotional videos featuring positive feedback from test group participants to portray majority consensus among triers, (3) “Tupperware”-like parties for Eclipse where participants received samples to pass around in their social circles and (4) the Eclipse website’s bulletin board as a forum for potential users to discuss the brand in their own words. These strategies targeted the brand’s likeliest adopters, recruited informal and credible representatives of the product unaffiliated with RJR, and controlled the information spread about the product. Conclusions Viral marketing techniques may be particularly useful to promote new tobacco products such as Eclipse that have limited appeal and need a highly motivated audience of early adopters and acceptors. Such techniques help evade the mass rejection that could follow mass promotion, circumvent marketing restrictions, and allow tobacco companies to benefit from health claims made by consumers. Cigarette manufacturers must be held accountable for perceived health benefits encouraged by all promotional activities including viral marketing. PMID:18332064

Full Text Available This paper aimed to characterize the anatomical structure of the wood of specimens of Mollinedia glabra (Spreng. Perkins growing in two contiguous formations of restinga vegetation at Praia Virgem, in the municipality of Rio das Ostras, RJ. Both the Open Palmae (OPS and the Sandy Strip Closed Shrub (SSCS formations are found in coastal regions that receive between 1,100 and 1,300 mm of rainfall per year. Sapwood samples were collected in both formations. Typical anatomical features for this species include: solitary vessels, radial multiples or clusters elements, that are circular to angular in outline, 5-15 barred scalarifor perforation plates, ood parenchya scanty, septate fiber-tracheids, and wide multiseriate rays with prismatic crystals. Statistical analyses indicated a significant increase in the frequency of vessel elements and an increase in fiber-tracheid diameters in OPS individuals. These characteristics are considered structural adaptations to increased water needs caused by a greater exposure to sunlight. Continuous pruning may be responsible for the tyloses observed in OPS plants. The greater lengths and higher frequencies of the rays in SSCS trees ay be due to the greater diaeters of their branches. ur results suggest that . glabra develops structural adaptations to the restinga micro-environmental variations during its development.Este trabalho objetiva caracterizar a estrutura anatômica do lenho de Mollinedia glabra, ocorrente em duas formações vegetais contíguas na restinga da Praia Virgem, município de Rio das Ostras, RJ.

Full Text Available The purpose of this study was analyze the biometry of the mangrove crab, Ucides cordatus (L., 1763, captured commercially in the Gargaú Mangrove (RJ, comparing common practices with the demands of Law no 52/2003 of IBAM A – Brazilian Agency of Environment and Natural Resources – and making inferences about the fishing community’s perception of the species. From April 2002 to March 2003, 571 specimens were analyzed and the highest frequency of males and females was registered in a carapace width of 6,0 6,5cm. The exploration of the mangrove crab is conducted all year round and the gear known as “redinha” is used in its capture, disrespecting the abovementioned law. However, the capture excludes ovigerous females and small-sized specimens, which reflects the fishing community’s concerns about this resource. The exploitation of this crab population probably interferes in its growth pattern, and managerial action needs to be implemented, considering not only the recommendations of scientific studies, but also the local fishermen’s knowledge of the species.

This study has the aim to assess the impact of accidental release of radionuclides postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models of hydrodynamic circulation and transport for the simulation of tritium dispersion caused by an accidental release in Ilha Grande Bay from the site of the future third plant in two circulation scenarios. The main difference between the scenarios is based on the enhancement of dilution of the highest concentrations in the last one. This dilution enhancement resulting in decreasing concentrations was observed only during the first two weeks, when they ranged from 1 x 10 9 to 5 x 10 5 Bq/m³ close to the Itaorna beach spreading just to Sandri Island. After 180 days, the plume could not be detected anymore in the bay, because their activities would be lower than the minimum detectable value (< 11 kBq/m³). (author)

An empirical model of the high-energy electron environment at Jupiter

Soria-Santacruz, M.; Garrett, H. B.; Evans, R. W.; Jun, I.; Kim, W.; Paranicas, C.; Drozdov, A.

We present an empirical model of the energetic electron environment in Jupiter's magnetosphere that we have named the Galileo Interim Radiation Electron Model version-2 (GIRE2) since it is based on Galileo data from the Energetic Particle Detector (EPD). Inside 8RJ, GIRE2 adopts the previously existing model of Divine and Garrett because this region was well sampled by the Pioneer and Voyager spacecraft but poorly covered by Galileo. Outside of 8RJ, the model is based on 10 min averages of Galileo EPD data as well as on measurements from the Geiger Tube Telescope on board the Pioneer spacecraft. In the inner magnetosphere the field configuration is dipolar, while in the outer magnetosphere it presents a disk-like structure. The gradual transition between these two behaviors is centered at about 17RJ. GIRE2 distinguishes between the two different regions characterized by these two magnetic field topologies. Specifically, GIRE2 consists of an inner trapped omnidirectional model between 8 to 17RJ that smoothly joins onto the original Divine and Garrett model inside 8RJ and onto a GIRE2 plasma sheet model at large radial distances. The model provides a complete picture of the high-energy electron environment in the Jovian magnetosphere from ˜1 to 50RJ. The present manuscript describes in great detail the data sets, formulation, and fittings used in the model and provides a discussion of the predicted high-energy electron fluxes as a function of energy and radial distance from the planet.

Full Text Available Royal jelly (RJ is popular among consumers around the world due to its perceived health benefits. The purpose of this study was to assess the levels of free and total amino acid profile as well as protein content in order to characterize Bulgarian RJ samples. A total of 17 fresh and commercial RJ samples from different regions of Bulgaria were analyzed. The results obtained show that proline (Pro, lysine (Lys, methionine (Met, aspartic acid (Asp, cysteine (Cys, histidine (His were major free amino acids (FAAs in RJ. The average content of Pro was 2.3 mg/g. The FAA content ranged from 5.5 to 6.2 mg/g of RJ. The most abundant total amino acids (TAAs were aspartic acid (Asp, glutamic acid (Glu, lysine (Lys, leucine (Leu, serine (Ser and proline (Pro. The average TAA content in fresh and commercial RJ were 129±10 and 114±8 mg/g, respectively. The results obtained for TAA content were used to establish a range for amino acid composition of Bulgarian RJ. The content of proteins was higher in fresh RJ than in commercial samples and this difference was significant (p<0.05. The following ranges were observed for fresh and commercial samples 14.7–17.3 and 12.5–14.9 mg/g, respectively. DOI: http://dx.doi.org/10.4314/bcse.v29i3.16

This solid reagent serves both as a source of carbon monoxide and a reducing agent for technetium. It was also used by Schibli and coworkers for the preparation of the corresponding {sup 188}Re precursor complex (“Schibili’s kit”).{sup 9} This approach involved the reduction of [{sup 188}Re]perrhenate eluate (1 ml) in neutral solution with 3 mg K{sub 2}[BH{sub 3}CO{sub 2}] and 5 mg BH3≅NH3 by incubation at 60 °C for 15 min. The amounts of reducing agents and acid (concentrated phosphoric acid) were carefully balanced not only to avoid fast hydrolysis of the boranes, but also to maintain a sufficiently low pH to stabilize reduced rhenium intermediates. The preparations resulted in yields >85 % of the desired precursor complex. In addition, perrhenate (7±3 %), colloidal {sup 188}ReO{sub 2} (<5 %), and a byproduct of unknown composition were also detected. To increase the yields even further, we evaluated the recently described borohydride exchange resin (BER) as an additional reducing agent and an anion scavengers.

We investigated the diet and foraging of the endemic teiid lizard Cnemidophorus littoralis in a restinga habitat in Jurubatiba, Macaé - RJ. The stomach contents were removed, analyzed and identified to the Order level. There was no relationship between C. littoralis morphological variables and number, length or volume of preys. Termites (48.7%) and larvae (35.5%) were the most important prey items which occurred in the examined lizards' stomachs. The diet did not differ between males and females. Cnemidophorus littoralis is an active forager and predominantly consumes relatively sedentary prey or prey that is aggregated in the environment. We also found an intact and undigested hatchling of the crepuscular/nocturnal gekkonid lizard Hemidactylus mabouia in the stomach of an adult male of C. littoralis, which indicates that C. littoralis is a potential source of mortality for individuals of H. mabouia in the restinga de Jurubatiba.

Full Text Available Este artigo analisou a desigualdade ambiental em Rio das Ostras-RJ por meio do mapeamento das condições adequadas de habitação, baseada nos índices de abastecimento de água, de esgotamento sanitário, de alfabetização, de renda, de disposição do lixo e de presença de vegetação, oriundos do Censo IBGE de 2010 e de imagens de satélite Cbers-2b e Landsat-5, de 2008. Os índices foram ponderados pelo método Analitic Hierarchy Process e agregados no software ArcGis 10.0, construindo o índice de desigualdade ambiental. O município de Rio das Ostras foi selecionado por apresentar um elevado crescimento populacional entre 2000 e 2010, seguido de um significativo crescimento econômico derivado da exploração de petróleo e gás na Bacia de Campos. Nesse sentido, tornou-se importante verificar se o crescimento populacional e econômico vinha acompanhando de condições de habitação adequadas para toda a população. O resultado expôs a presença de desigualdade ambiental em Rio das Ostras, afetando principalmente a população de menor renda, com maiores porcentagens de analfabetos e localizados no limite da área urbanizada e na área rural, cujas áreas apresentaram deficiência na oferta de serviços e infraestrutura. Concluiu-se que a distribuição condições adequadas de habitação avaliada por este trabalho não é homogênea e segue a lógica de valorização da terra urbana para o processo de especulação imobiliária em Rio das Ostras. A presença da desigualdade ambiental também representa dificuldades na garantia da sustentabilidade urbana, com diversas áreas desprovidas de condições de habitação em que, por isso, acabam por impactar o meio ambiente.

This work is part of PRODETAB/EMBRAPA - 39th Project – and was developed in Goura Vrindávna Farm, Paraty - RJ. 28 multipurpose arboreal species were cultivated in three agroforestry treatments, Minimum SAFRA (simplified system of the banana culture enrichment, Absolute SAFRA (dense and diversified system and Modified SAFRA (the same composition of the latter SAFRA plus soil fertilization. For evaluating nutrients deposition through litter fifteen months after planting, samples of three Safra and two control treatments, banana culture and area in fallow, were collected with 625cm2 collectors. Macro and micronutrients determinations were done in the samples. The Minimum SAFRA was the system that deposited the greatest weight in litter (32.4 t.ha-1 and the greatest content of micro and macronutrients. Excepting C and H, N was the one which presented greatest content in the five treatments, and Fe was the micronutrients of major deposition. The vegetation pruning in the SAFRA benefited the nutrients cycling and contributed to its content elevation in litter. Considering the nutrients deposition through litter, the SAFRAs were the most promissory systems in the re-establishing of these ecological functions, when compared to area in fallow and banana monoculture.

Full Text Available RESUMO Este trabalho apresenta um modelo para determinar a fragilidade ambiental em bacias hidrográficas. O estudo foi realizado na Bacia do Rio Aldeia Velha, RJ, localizada na zona de contato e transição entre a baixada litorânea e o relevo montanhoso da Serra do Mar. Fatores que influenciam a ocorrência de processos erosivos foram integrados por algoritmos em um SIG para construção de classes de fragilidade. A análise multicriterial considerou o modelo numérico de terreno, dados oficiais sobre variáveis ambientais, imagem orbital de alta resolução e a opinião de especialistas. Através de informações secundárias sobre pedologia, intensidade das chuvas e declividade do terreno gerou-se o Mapa de Fragilidade Potencial (MFP. Através da combinação desse mapa com informações sobre uso e cobertura da terra obteve-se o Mapa da Fragilidade Emergente (MFE. Os resultados mostram que mais de 70% da área da bacia possui fragilidade ambiental considerada alta ou muito alta, tanto potencial como emergente. Os Processos Erosivos Aparentes (PEA relacionaram-se positivamente com as áreas de alta fragilidade nos produtos cartográficos finais, destacando regiões mais propensas à intensificação de movimentos de massa e prioritárias para prevenção contra perda de solo. Os modelos geraram informações importantes para o planejamento territorial, possibilitando um zoneamento acessível e de fácil atualização para as prefeituras municipais e organizações da sociedade civil, inclusive para o monitoramento das áreas de alta fragilidade ambiental.

Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally 232 Tb, derived from the MCW site. The survey typically includes direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this site, 31 Schlosser Drive, Rochelle Park, New Jersey (RJ003), was conducted on July 14, 1991. Results of the survey demonstrated no radionuclide concentrations in excess of the DOE Formerly Utilized Sites Remedial Action Program criteria.

Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook.

Full Text Available The present article is characterized by the analysis of the insertion of engineer José de Oliveira Reis in a specific moment (not the only one of the continued construction process of the municipal administrative instances in charge of urban planning and urban plans in Rio de Janeiro. From 1956 through 1960, José de Oliveira Reis reassumes, for the last time, the Department of Urban Planning of Distrito Federal City Hall, actively taking part in the ascribed institutional construction-creationimprovement process of municipal organs responsible for the planning, financing and execution of public urban works. In this case, for the creation of the Superintendency of Urban Planning and Sanitation (SURSAN of the Special Fund for Public Works, and for the implementation of the Execution Plan issued in deliberations in Law no. 899, of November 28th 1957. The understanding of the national context – in the scope of the Brazilian Municipalist Movement – of this whole process of the creation of municipal instances in the urban planning sector, during the 1950s, is also fundamental for comprehending engineer José de Oliveira Reis’s positions as the director of the Department. Centered in the basic precepts of political and financial autonomy, Brazilian Municipalism preconizes an important set of deliberations resulting from National Congresses of Brazilian Municipalities – especially from the four first ones - , among which the need for the implementation of mechanisms and instruments for increasing municipal budgets in the execution of works, that is, “financing for urbanizing”.

CFD Rocha

Full Text Available The gekkonid lizard Hemidactylus mabouia is an exotic species in Brazil and is found in different ecosystems. This species was recorded at Ilha Grande, RJ, one of the largest insular remains of the Atlantic Rainforest in Brazil. In this study, the occurrence of H. mabouia was determined throughout the island, including the rain forest, restinga and anthropic environments. We used the active search method in points along 19 trails that surround Ilha Grande. At each regular interval of 100 m, we searched for the presence of H. mabouia. The species was recorded in a total of 100 points among the 719 sampled and, in all cases, the occurrence of the lizard corresponded to points located in anthropic or perianthropic areas. As most of Ilha Grande is covered by dense tropical rain forest, we believe this has restricted the invasion of H. mabouia in natural environments within the island.

The geochemistry dispersion of the metals in aquatic environment is related to the physical chemistry proprieties of these elements as to their interaction by sorption on and desorption from solid particles. These interaction must be understood within the environmental dynamic, with its hydrological, sedimentological, chemical, physical and biological processes that may take the toxic elements (stables metals and radionuclides) to the bio alimentary chain. It was observed at the Ribeira Bay, its hydrodynamic behaviour through the suspension material and particulate organic carbon dispersion. And, through the textural, mineralogical and chemical parameters it was observed the behaviour of the geochemistry processes of the sedimentary materials and the influence that they may submit to the metals dispersion.

Full Text Available Summary Background Dengue, a mosquito-borne viral infection caused by one of the four dengue virus (DENV serotypes (DENV-1 to 4, replicate alternately on the mosquito vector and human host and are responsible for infections throughout tropical and subtropical regions of the world. In Brazil, the disease has become a major public health problem and the introduction of DENV-3 in 2000 in Rio de Janeiro (RJ was associated with severe dengue epidemics. The potential emergence of strains associated with severe disease highlights the need for the surveillance of DENV in human host and vectors. Methods Aiming to contribute for DENV phylogenetic and vector-virus-human host studies, we sequenced the entire genome of one DENV-3 isolated from naturally infected Aedes aegypti from RJ in 2001 and characterized the 3’ UTR from strains isolated from mosquitoes and humans. Mosquitoes were pooled and submitted to virus isolation in Ae. albopictus C6/36 cells and the infecting serotype was identified by immunofluorescence using type-specific monoclonal antibody. Sequence analysis was performed using BioEdit software, the multiple alignments were performed using CLUSTAL W and the phylogenetic analysis by MEGA 5, using the Neighbor-joining method. Secondary structure prediction was performed by using the MFOLD program. Results Exclusive substitutions and a substitution leading to a stop codon on the NS5 gene were observed in the DENV-3 isolated from a naturally infected Ae. aegypti and fully sequenced. As an 8- nucleotides deletion was observed within the 11- nucleotides (nts insertion on the variable region (VR from the 3′UTR in this isolate, we further sequenced other DENV-3 from both mosquitoes and humans. The majority of DENV-3 from RJ analyzed were characterized by the 11-nts insertion in the VR of the 3′UTR, despite the observation of strains carrying the 8-nts deletion. The latter presented similar secondary structures, however not all strains

Full Text Available Diazepam suppositories are widely used by children and elderly, and require close attention to quality control because it is a controlled prescription drug. The objective of the study was to analyze diazepam suppositories manipulated in Campos dos Goytacazes, RJ, to verify if they are within the required quality standards, and offer safety and efficiency to patients. We analyzed samples of 5mg diazepam suppositories acquired in five randomly selected pharmacies, identified as Pharmacy A, Pharmacy B, Pharmacy C, Pharmacy D, and Pharmacy E. We ran tests on average weight, organoleptic control, hardness, melting point, and dissolution. Data was analyzed and compared with the requirements of the Brazilian Pharmacopoeia. This analysis was made over a table in Excel. We conclude that only C Pharmacy was approved in all tests, and this is the only laboratory that has analyzed the quality of the product warranty. Laboratories A, B, D and E have been approved in some tests, and failed one or more tests. To ensure quality control, suppositories needed to pass in all tests, which was not the case of these labs. Therefore, we recommended the following procedures to the investigated laboratories: changes in packaging, greater precision in handling, quality control prior to dispensing the product, and efficient pharmaceutical care service.

We present the draft genome for the Rickettsia endosymbiont of Ixodes scapularis (REIS), a symbiont of the deer tick vector of Lyme disease in North America. Among Rickettsia species (Alphaproteobacteria: Rickettsiales), REIS has the largest genome sequenced to date (>2 Mb) and contains 2,309 genes across the chromosome and four plasmids (pREIS1 to pREIS4). The most remarkable finding within the REIS genome is the extraordinary proliferation of mobile genetic elements (MGEs), which contributes to a limited synteny with other Rickettsia genomes. In particular, an integrative conjugative element named RAGE (for Rickettsiales amplified genetic element), previously identified in scrub typhus rickettsiae (Orientia tsutsugamushi) genomes, is present on both the REIS chromosome and plasmids. Unlike the pseudogene-laden RAGEs of O. tsutsugamushi, REIS encodes nine conserved RAGEs that include F-like type IV secretion systems similar to that of the tra genes encoded in the Rickettsia bellii and R. massiliae genomes. An unparalleled abundance of encoded transposases (>650) relative to genome size, together with the RAGEs and other MGEs, comprise ∼35% of the total genome, making REIS one of the most plastic and repetitive bacterial genomes sequenced to date. We present evidence that conserved rickettsial genes associated with an intracellular lifestyle were acquired via MGEs, especially the RAGE, through a continuum of genomic invasions. Robust phylogeny estimation suggests REIS is ancestral to the virulent spotted fever group of rickettsiae. As REIS is not known to invade vertebrate cells and has no known pathogenic effects on I. scapularis, its genome sequence provides insight on the origin of mechanisms of rickettsial pathogenicity.

To identify and rate reproductive endocrinology and infertility (REI) mobile applications (apps) targeted toward REI providers. A list of REI apps was found in both the Apple iTunes and Google Play stores using the following seven MeSH terms: reproductive endocrinology, REI, infertility, fertility, In Vitro Fertilization, IVF, and embryology. Patient-centered apps were excluded. The remaining apps were then evaluated for accuracy using reliable references. Mobile technology. None. Accurate apps were evaluated for comprehensiveness (the extent of the ability to aid in clinical decision-making) and rated with objective and subjective components using the APPLICATIONS scoring system. Using the seven REI-related MeSH terms, 985 apps and 1,194 apps were identified in the Apple iTunes and Google Play stores, respectively. Of these unique apps, only 20 remained after excluding patient-centered apps. Upon further review for applicability to REI specifically and content accuracy, only seven apps remained. These seven apps were then rated using the APPLICATIONS scoring system. Only 0.32% of 2,179 apps reviewed for this study were useful to REI providers. There is potential for further mobile resource development in the area of REI, given the limited number and varying comprehensiveness and quality of available apps.

As a step towards development of a high-resolution ion mobility mass spectrometer using the orbitrap mass analyzer platform, we describe herein a novel reverse-entry ion source (REIS) coupled to the higher-energy C-trap dissociation (HCD) cell of an orbitrap mass spectrometer with extended mass range. Development of the REIS is a first step in the development of a drift tube ion mobility-orbitrap MS. The REIS approach retains the functionality of the commercial instrument ion source which permits the uninterrupted use of the instrument during development as well as performance comparisons between the two ion sources. Ubiquitin (8.5 kDa) and lipid binding to the ammonia transport channel (AmtB, 126 kDa) protein complex were used as model soluble and membrane proteins, respectively, to evaluate the performance of the REIS instrument. Mass resolution obtained with the REIS is comparable to that obtained using the commercial ion source. The charge state distributions for ubiquitin and AmtB obtained on the REIS are in agreement with previous studies which suggests that the REIS-orbitrap EMR retains native structure in the gas phase.

Full Text Available Within the period so called renovatio, many principles contained in the Roman legal sources have been explained in a new and innovative way, influencing the history of juridical thought and contributing to the development of the European legal experience. In fact, the principle "Rei publice interest it crimina remaneant impunita" (mentioned in two decretals of Innocent III: i.e. the Inauditum in 1199 and i.e. the Ut famae in 1203 has an essential role in the development of the conceptual system of modern criminal law. The content of this study will be, on the one hand, the detailed study of historical iter by which this principle has been consolidated and has been embraced by canonical experience and, more generally, in the Western one; on the other hand, it will analyse both from a technical and a metagiuridico point of view the origin of such formula and on the contribution that Christian theology might have given by clarifying and specifying its meaning. Therefore, it’s clear the importance of this principle in the development of the European legal system and, broadly, in the Western legal experience.

In many areas of the world, studies of marine debris are conducted with an emphasis on analyzing their composition, quantification and distribution on sandy beaches. However, in Brazil, studies are still restricted to some areas of the coast, and the quantities and the spatial and temporal patterns are unknown. To enhance the marine debris information in these areas, we selected the Itaipu and Itacoatiara beaches in Niterói, RJ, to collect, quantify and qualify the solid residues present in their sands. We collected 12 samples and recorded 118.39 kg of residues in Itaipu and 62.94 kg in Itacoatiara. At both beaches, the largest portion of debris was located on the upper part of the beach. Several debris items were related to food and drink consumption on the beaches, which indicated the contribution of beach users to pollution. Most of the debris was plastic. The greatest amount of debris was found at Itaipu in January and February and at Itacoatiara in January and March, months related to both the holiday season and abundant rainfall. The results demonstrated the necessity to implement an Environmental Education project for these areas to reduce its degradation. Copyright © 2015 Elsevier Ltd. All rights reserved.

Traditional ratio measures of efficiency, including feed conversion ratio (FCR), gross milk efficiency (GME), gross energy efficiency (GEE) and net energy efficiency (NEE) may have some statistical problems including high correlations with milk yield. Residual energy intake (REI) or residual feed intake (RFI) is another criterion, proposed to overcome the problems attributed to the traditional ratio criteria, but it does not account for production or intake levels. For example, the same REI value could be considerable for low producing and negligible for high producing cows. The aim of this study was to propose a new measure of efficiency to overcome the problems attributed to the previous criteria. A total of 1478 monthly records of 268 lactating Holstein cows were used for this study. In addition to FCR, GME, GEE, NEE and REI, a new criterion called proportional residual energy intake (PREI) was calculated as REI to net energy intake ratio and defined as proportion of net energy intake lost as REI. The PREI had an average of -0·02 and range of -0·36 to 0·27, meaning that the least efficient cow lost 0·27 of her net energy intake as REI, while the most efficient animal saved 0·36 of her net energy intake as less REI. Traditional ratio criteria (FCR, GME, GEE and NEE) had high correlations with milk and fat corrected milk yields (absolute values from 0·469 to 0·816), while the REI and PREI had low correlations (0·000 to 0·069) with milk production. The results showed that the traditional ratio criteria (FCR, GME, GEE and NEE) are highly influenced by production traits, while the REI and PREI are independent of production level. Moreover, the PREI adjusts the REI magnitude for intake level. It seems that the PREI could be considered as a worthwhile measure of efficiency for future studies.

This work aimed to assessing Strongyluris sp. cysts distribution pattern in the several inner organs from pallial system of Achatina fulica Bowdich, 1822. Also we verified if there is a relationship between the mollusk size and the number of specimens from parasites collected from two touristic villages in Ilha Grande (Angra dos Reis, Rio de Janeiro state): Vila Dois Rios (VDR) and Vila do Abraão (ABR). The samples were obtained through a field work conducted bimonthly during 2007, 2008, 2010, and 2011, at both locations. Height and width were measured from shells collected, and the all specimens were classified in different classes: class 1 - biomass and a larger area of the pallial system, allowing an efficient parasite colonization. Other possible explanation could be the long exposure of the molluscs of class 3 to the parasites, which allowed a longer time to the larvae to allocate themselves.

Full Text Available Sanitation actions are rare in the communities of Manguinhos, so evaluation of the sanitary conditions of the river waters and the peridomestic soils of the communities allows the diagnosis of the risk of contamination. This study evaluated coliform levels (total coliforms and Escherichia coli by the filter membrane method, and parasitological (by adapted Lutz and Baermann-Moraes methods in the waters and soils of the Faria-Timbó, Jacaré and Canal do Cunha Rivers that pass through the communities of the Territory of Manguinhos, RJ, according to the standards established in Brazilian legislation. In all points of the rivers, the water was unfit, with an average level of Escherichia coli 3,800 times higher than that standardized in CONAMA Resolution No. 274/2000. Larvae, helminths eggs and protozoan oocysts were observed. Soil samples were also unfit, with mean total coliform level 77,000 times higher than that considered acceptable by SMAC Resolution 468/2010. The Escherichia coli average level was 53,000 times higher than that permitted by the legislation. However, helminths eggs were found in only one soil sample. It was concluded that the lack of sanitation in this locality results in the high coliform and parasitological levels of the river waters and in the peridomestic soils, and that immediate modifications are needed to the Brazilian environmental paradigm, which uses its water bodies as sewage disposal ditches.

Royal jelly promotes DAF-16-mediated proteostasis to tolerate β-amyloid toxicity in C. elegans model of Alzheimer's disease.

Numerous studies have demonstrated that dietary intervention may promote health and help prevent Alzheimer's disease (AD). We recently reported that bee products of royal jelly (RJ) and enzyme-treated royal jelly (eRJ) were potent to promote healthy aging in C. elegans. Here, we examined whether RJ/eRJ consumption may benefit to mitigate the AD symptom in the disease model of C. elegans. Our results showed that RJ/eRJ supplementation significantly delayed the body paralysis in AD worms, suggesting the β-amyloid (Aβ) toxicity attenuation effects of RJ/eRJ. Genetic analyses suggested that RJ/eRJ-mediated alleviation of Aβ toxicity in AD worms required DAF-16, rather than HSF-1 and SKN-1, in an insulin/IGF signaling dependent manner. Moreover, RJ/eRJ modulated the transactivity of DAF-16 and dramatically improved the protein solubility in aged worms. Given protein solubility is a hallmark of healthy proteostasis, our findings demonstrated that RJ/eRJ supplementation improved proteostasis, and this promotion depended on the transactivity of DAF-16. Collectively, the present study not only elucidated the possible anti-AD mechanism of RJ/eRJ, but also provided evidence from a practical point of view to shed light on the extensive correlation of proteostasis and the prevention of neurodegenerative disorders.

Genetic counselors believe fertility preservation and preimplantation genetic diagnosis (PGD) discussions to be a part of their role when counseling BRCA1/2 mutation-positive patients. This study is the first to explore reproductive endocrinologists' (REI) practices and attitudes regarding involvement of genetic counselors in the care of BRCA1/2 mutation carriers seeking fertility preservation and PGD. A survey was mailed to 1000 REIs from Reproductive Endocrinology & Infertility (SREI), an American Society for Reproductive Medicine (ASRM) affiliate group. A 14.5 % response rate was achieved; data was analyzed using SPSS software. The majority of participating REIs were found to recommend genetic counseling to cancer patients considering fertility preservation (82 %) and consult with a genetic counselor regarding PGD for hereditary cancer syndromes (92 %). Additionally, REIs consult genetic counselors regarding PGD patient counseling (88 %), genetic testing (78 %), and general genetics questions (66 %). Two areas genetic counselors may further aid REIs are: elicitation of family history, which is useful to determine fertility preservation and PGD intervention timing (32 % of REIs utilize a cancer family history to determine intervention timing); and, interpretation of variants of uncertain significance (VOUS) as cancer panel genetic testing becomes more common (36 % of REIs are unfamiliar with VOUS). Given our findings, the Oncofertility Consortium® created an online resource for genetic counselors focused on fertility preservation education and communication strategies.

Jun, I.; Garrett, H. B.; Ratliff, J. M.

2003-04-01

Measurements of the high energy, omni-directional electron environment by the Galileo spacecraft Energetic Particle Detector (EPD) were used to study the high energy electron environment in the Jovian magnetosphere, especially in the region between 8 to 18 Rj (1 Rj = 1 Jovian radius = 71,400 km). 10-minute averages of the EPD data collected between Jupiter orbit insertion (JOI) in 1995 and the orbit number 33 (I33) in 2002 form an extensive dataset, which has been extremely useful to observe temporal and spatial variability of the Jovian high energy electron environment. The count rates of the EPD electron channels (0.174, 0.304, 0.527, 1.5, 2.0, and 11 MeV) were grouped into 0.5 Rj or 0.5 L bins and analyzed statistically. The results indicate that: (1) a log-normal Gaussian distribution well describes the statistics of the high energy electron environment (for example, electron differential fluxes) in the Jovian magnetosphere, in the region studied here; (2) the high energy electron environments inferred by the Galileo EPD measurements are in a close agreement with the data obtained using the Divine model, which was developed more than 30 years ago from Pioneer 10, 11 and Voyager 1, 2 data; (3) the data are better organized when plotted against magnetic radial parameter L than Rj; (4) the standard deviations of the 0.174, 0.304, 0.527 MeV channel count rates are larger than those of the 1.5, 2.0, 11 MeV count rates in 12 Rj. These observations are very helpful to understand short- and long-term, and local variability of the Jovian high energy electron environment, and are discussed in detail.

Full Text Available The aim of this study was to describe and compare the succession of intertidal benthic communities in two areas at Guanabara Bay, RJ, Brazil: Urca, an area submitted to moderated organic pollution and Catalão, an extremely polluted area. Three transects in each area were scraped one month before the beginning of this study in order to evaluate the recruitment (recruitment-treatments. Three other transects were monitored without manipulation (monitoring treatments. Species composition and relative abundance were evaluated monthly between September and December, 2000. A total of 26 species was found at Urca and 13 at Catalão. The percent cover of the most abundant organisms was not similar between treatments at Urca after four months, while in Catalão, the similarity was 72% in the second month. The faster community development and recovery at the most polluted area was probably related to the existence of simple and resilient communities in more impacted areas.O objetivo deste estudo foi descrever e comparar a sucessão das comunidades bentônicas da região entre-marés, em duas áreas na Baía de Guanabara, RJ, Brasil: Urca, uma área sujeita a moderado nível de poluição orgânica, e Catalão, uma área extremamente poluída.

Degree of threat to the biological diversity in the Ilha Grande State Park (RJ) and guidelines for conservation.

The State Park of Ilha Grande is only a part (5,594 hectares) of the entire island (19,300 hectares) which is located off the south coast of Rio de Janeiro state, between the cities of Mangaratiba and Angra dos Reis. Approximately half of the Park area (47%) is covered by dense Atlantic forest. The secondary forest growth is in a process of ecological succession close to attaining maturity (43%) and the remaining part (10%) is composed of human-altered areas (1%), rocky outcrops with herbaceous vegetation (7%), mangroves and beaches (2%). The fauna is well represented but already shows signs of degradation with introduced species. The analysis of the degree of threat has shown that the dense forest habitat has a relatively stable status of conservation while the secondary forest, the mangrove and the herbaceous vegetation on rocky outcrops (and their fauna) are categorized as vulnerable. The area altered by human occupation is considered threatened. Since the coastal area where Ilha Grande is located is well known for its beautiful scenery (known as the green coast, because of the contrast between the ocean and the Atlantic forest covering the Serra do Mar mountain chain). There is a strong possibility for tourism to become the means in which to achieve economic sustainability for conservation. Contradictorily, tourism is also the major threat to local biodiversity and its landscape units. Because tourism is not organized and controlled, during high season the numbers grow above local capacity, giving rise to a proliferation of hotels, guesthouses and camping grounds. The resulting untreated open sewage, random garbage disposal and other harmful activities form the major threats to biodiversity.

It was postulated, in the cooling system of the core, a LOCA, where 431 m 3 of soda almost instantaneously was lost. This inventory contained 1.87x10 10 Bq/m 3 of tritium, 2.22x10 7 Bq/m 3 of cobalt,3.48x10 8 Bq/m 3 of cesium and 3.44x10 10 Bq/m 3 of iodine and was released in liquid form near the Itaorna cove, Angra dos Reis - RJ. Applying the model in the proposed scenario (Angra 1 and 2 in operation and Angra 3 progressively reducing the capture and discharge after the accident), the simulated dilution of the specific activity of radionuclide spots, reached values much lower than report levels for seawater (1,1x10 6 Bq/m 3 , 1,11x10 4 Bq/m 3 and 1,85x10 3 Bq/m 3 ) after 22 hours, respectively for 3 H, 60 Co, 131 I and 137 Cs. From the standpoint of public exposure to radionuclide dispersion, the results of activity concentration obtained by the model suggest that the observed radiological impact is negligible. Based on these findings, we conclude that there would be no radiological impact related to a further release of controlled effluent discharges into Itaorna cove. (author)

Mapping of the environmental radioactivity of the Ilha Grande, Rio de Janeiro State - preliminary results

2000-01-01

The study of the environmental radioactivity and its correlation with geological parameters is of great relevance, due to the fact that natural radiation is the main exposure source for the humanity. The analysis of the environmental radiation constituted by natural and antropogenics radioactive elements, and its monitoring along the time is of great importance to evaluate the impact of the human activities on the environment. These results may be useful as a parameter for the monitoring of the activities developed in the nuclear compound of Angra dos Reis, RJ. The characterization of the environmental radiation is done using an ionization chamber that measures the exposure rate one meter of distance from the ground. A GPS and local maps are being used on the mapping of the analyzed points. The obtained results are between 6 μ R h -1 and 28 μ R h -1 . The highest exposure rates can be associated to the concentrations of minerals, for example, Monazite and Zircon. Some areas are in the mouths of some rivers, located in geological fractures, that regulate the geomorphology and the formation of the drainage nets of the area. Those parameters can contribute to the dispersion and re-concentration of those minerals in several specific points of the island. (author)

The use of nuclear power plants for electricity supply is presently considered as an important factor to be considered in any energy matrix to ensure the diversification and availability criteria. Currently several countries resumed or started programs for the construction of nuclear power plants of new projects, with extremely improved security levels. Additionally, events and accidents in nuclear power plants have contributed substantially to the occurrence of design modifications and/or update the regulatory requirements to further enhance operational safety of these plants. Nowadays, one of the regulatory requirements necessary for the selection of a site for construction and operation of nuclear installations is the public hearing and discussion. The city of Angra dos Reis has two nuclear power plants in operation and a third one under construction. There are also, plans for the construction of more nuclear power plants in the country, to meet the growing demand for electricity. The first nuclear power plant in Brazil went into operation in 1983 and the second in 2000. The selection of the site for construction of these plants was due to political, economic and strategic factors, present in Brazil, in the decade of 70. The licensing process in de 70's decade did not involve an extensive participation of the society as a whole and of the local population, such as the occurrence of public hearings and the wide possibility for discussion and debate about the acceptance of the location of the plant. In the initial years of operation of the Angra 1 nuclear power plant, the level of knowledge of the local population was practically null, occurring mainly in local clarifications, made through seminars and lectures on special occasions, such as at the time of the annual exercises of the external emergency plan, specific information Programs or technical visits of educational institutions and the Government to Angra dos Reis Nuclear power plant.

Full Text Available Previous research on the Rational-Experiential Inventory (REI; Epstein, Pacini, Denes-Raj and Heier, 1996 has produced inconsistent results concerning its predictive validity with specific reasoning tasks. To evaluate the predictive capacity of the REI in greater detail we used ten tasks requiring different types of reasoning (e.g., deductive and probabilistic. The latest version of the REI (Pacini and Epstein, 1999 was adapted to Spanish and answered by 120 participants. Findings suggest that thinking styles of processing as measured by the REI reflect the existence of individual differences, but that its predictive capacity is limited to some particular reasoning tasks. Some explanations for these limitations are discussed within the context of dual-reasoning theories

It is surrounded by high relieves, which form a peculiar environment called riá, with little river input and limited water exchange with the Atlantic Ocean. These features make the Saco do Mamangua an ideal environment to study sedimentary carbon cycling under well-constrained boundary conditions in order to investigate if tropical coastal environments serve dominantly as potential carbon sinks or sources. In this work we integrate geochemical data from marine sediments and pore waters in the Saco do Mamangua with mapping of benthic microbial communities, in order to unravel the biogeochemical carbon cycling linked to the production of biogenic methane. Our results reveal that carbon cycling occurs in two parallel pathways. The Saco do Mamangua receives organic carbon both by surface runoff and by primary production in the water column. A large part of this organic carbon is buried within the sediment resulting in the production of biogenic methane, which gives rise to methane seepages at the sea floor. These methane seeps sustain methanotrophic microbial communities in the sediment pore water, but also escapes into the atmosphere by ebullition. Consequently, the sediments of Saco do Mamangua acts simultaneously as carbon sink and carbon source. Future work will allow us to accurately quantify the actual carbon fluxes and calculate the net carbon balance in the local environment.

Dosimetric pens are direct reading personal dosemeters that are used in the practices of radiation protection in industries, hospitals, universities, and research institutes in the country. Quality control of measurements made with these instruments must include their periodical calibration in one of the laboratories of the Calibration Laboratory Network for Ionizing Radiation with the aim to compare the behavior of the measurements made in dosimetric pens of different models and manufacturers, submitted for calibration in the LNMRI/IRD/CNEN (Brazilian Lab for Metrology of Ionizing Radiations of the Institute for Radioprotection and Dosimetry of the Brazilian Nuclear Energy Commission), RJ or national reference laboratory and a member of the Network, in the years of 2000 to 2002. The parameters considered for the purpose of this work were: accuracy and linearity of response and measurement uncertainty evaluated. The results show that among the analyzed models there are changes in behavior

Full Text Available One of the most important challenges in the study of aging is to discover compounds with longevity-promoting activities and to unravel their underlying mechanisms. Royal jelly (RJ has been reported to possess diverse beneficial properties. Furthermore, protease-treated RJ (pRJ has additional pharmacological activities. Exactly how RJ and pRJ exert these effects and which of their components are responsible for these effects are largely unknown. The evolutionarily conserved mechanisms that control longevity have been indicated. The purpose of the present study was to determine whether RJ and its related substances exert a lifespan-extending function in the nematode Caenorhabditis elegans and to gain insights into the active agents in RJ and their mechanism of action.We found that both RJ and pRJ extended the lifespan of C. elegans. The lifespan-extending activity of pRJ was enhanced by Octadecyl-silica column chromatography (pRJ-Fraction 5. pRJ-Fr.5 increased the animals' lifespan in part by acting through the FOXO transcription factor DAF-16, the activation of which is known to promote longevity in C. elegans by reducing insulin/IGF-1 signaling (IIS. pRJ-Fr.5 reduced the expression of ins-9, one of the insulin-like peptide genes. Moreover, pRJ-Fr.5 and reduced IIS shared some common features in terms of their effects on gene expression, such as the up-regulation of dod-3 and the down-regulation of dod-19, dao-4 and fkb-4. 10-Hydroxy-2-decenoic acid (10-HDA, which was present at high concentrations in pRJ-Fr.5, increased lifespan independently of DAF-16 activity.These results demonstrate that RJ and its related substances extend lifespan in C. elegans, suggesting that RJ may contain longevity-promoting factors. Further analysis and characterization of the lifespan-extending agents in RJ and pRJ may broaden our understanding of the gene network involved in longevity regulation in diverse species and may lead to the development of nutraceutical

The U-Pb dating in zircon based on air-abrasion method, whole rock Rb-Sr one, and K-Ar ones in biotite and amphibole of the samples collected from the Cabo Frio Region, Ribeira Orogenic Belt, have been carried out. The concordia diagram of the U-Pb dating indicates 2 different ages: 1981 ± 18 Ma for the upper intersect corresponding to the Transamazonic Cycle, and 488 ± 55 Ma for the lower one, Brazilian Cycle. The former is interpreted as age of zircon formation and the latter, as the time elapsed since epsodic lead loss. The whole rock Rb-Sr dating also shows Transamazonic age: 1799 ± 62 Ma, IR=0.706, and MSWD+0.570. The K-Ar age in amphibole is 571 ± 44 Ma and that in biotite is 474 ± 6 Ma. These data lead to the conclusion that the rocks of this region was formed in the Trasamazonic Cycle and remetamorphosed in the Brazilian Cycle. (author)

Full Text Available Royal jelly (RJ has been used worldwide for many years as medical products, health foods and cosmetics. Since RJ contains testosterone and has steroid hormone-type activities, we hypothesized that it may have beneficial effects on osteoporosis. We used both an ovariectomized rat model and a tissue culture model. Rats were divided into eight groups as follows: sham-operated (Sham, ovariectomized (OVX, OVX given 0.5% (w/w raw RJ, OVX given 2.0% (w/w RJ, OVX given 0.5% (w/w protease-treated RJ (pRJ, OVX given 2.0% (w/w pRJ, OVX given 17β-estradiol and OVX given its vehicle, respectively. The Ovariectomy decreased tibial bone mineral density (BMD by 24%. Administration of 17β-estradiol to OVX rats recovered the tibial BMD decrease by 100%. Administration of 2.0% (w/w RJ and 0.5–2.0% (w/w pRJ to OVX rats recovered it by 85% or more. These results indicate that both RJ and pRJ are almost as effective as 17β-estradiol in preventing the development of bone loss induced by ovariectomy in rats. In tissue culture models, both RJ and pRJ increased calcium contents in femoral-diaphyseal and femoral-metaphyseal tissue cultures obtained from normal male rats. However, in a mouse marrow culture model, they neither inhibited the parathyroid hormone (PTH-induced calcium loss nor affected the formation of osteoclast-like cells induced by PTH in mouse marrow culture system. Therefore, our results suggest that both RJ and pRJ may prevent osteoporosis by enhancing intestinal calcium absorption, but not by directly antagonizing the action of PTH.

Recent studies suggest that royal jelly (RJ) and its related substances may have antiaging properties. However, the molecular mechanisms underlying the beneficial effects remain elusive. We report that the effects of RJ and enzyme-treated RJ (eRJ) on life span and health span in Caenorhabditis elegans (C elegans) are modulated by the sophisticated interplays of DAF-16, SIR-2.1, HCF-1, and 14-3-3 proteins. Dietary supplementation with RJ or eRJ increased C. elegans life span in a dose-dependent manner. The RJ and eRJ consumption increased the tolerance of C elegans to oxidative stress, ultraviolet irradiation, and heat shock stress. Our genetic analyses showed that RJ/eRJ-mediated life-span extension requires insulin/IGF-1 signaling and the activities of DAF-16, SIR-2.1, HCF-1, and FTT-2, a 14-3-3 protein. Earlier studies reported that DAF-16/FOXO, SIR-2.1/SIRT1, FTT-2, and HCF-1 have extensive interplays in worms and mammals. Our present findings suggest that RJ/eRJ-mediated promotion of longevity and stress resistance in C elegans is dependent on these conserved interplays. From an evolutionary point of view, this study not only provides new insights into the molecular mechanisms of RJ's action on health span promotion in C elegans, but also has imperative implications in using RJ/eRJ as nutraceuticals to delay aging and age-related disorders. © The Author 2014.

Full Text Available The aim of this study were investigate the reproductive biology of the fish Leporinus copelandii, a specie at risk of extinction in the lower Paraíba do Sul River basin. During a period of 14 months, a total of 143 females of red-piau were captured, between Itaocara and Campos dos Goytacazes cities (RJ, Brazil. A histological study shows four stages of the oocyte development (I, II, III and IV and five stages of the reproductive cycle of females: rest (1, initial maturation (2A, intermediary (2B, advanced (2C and spawned (4 were identified. The pattern of L. copelandii oocyte development suggests development type synchronous in two groups, characterizing total spawning. Spawned females were captured in November, two months after the peak of frequency of competent females for reproduction. Histologically, a little occurrence of empty follicles was observed in spawned females. The medium diameter of the type IV oocyte of the spawned females (1475.1 ± 884.3mm was significantly larger (Tukey, P <0.001; VC = 41.73%; n = 259 than advanced maturation females (1202.6 ± 245.3mm, what allows suggesting that the study place probably doesn't represent the reproductive area of L. copelandii.

on regions and tends to increase when earthquakes occurred outward the network. Depth differences for 70 percent of events are less than 20km and original time differences for 48 percent within one second. In addition to JMA magnitude (MJMA), which is estimated from moment magnitude, REIS estimates a new scaling parameter called intensity magnitude (MI), which is defined from observed P wave seismic intensity (Yamamoto et al., 2008). Our statistical results show that these two kinds of magnitudes are reasonably determined. Either MJMA or MI by REIS for 94 percent of events has differences less than 1.0 compared with reported JMA catalog. However, the difference increases with values of the magnitude. There is an apparent underestimation of MJMA for large earthquakes because the first report is issued when the rupture is still undergoing. Moreover, there are cases when most of Hi-net seismograms close to epicenter are clipped, but still these data are used for the determination of the lower limit of magnitude. We are making an EEWS using real-time strong motion network data for the better estimate of earthquake magnitude and seismic intensity.

Efficacy of independence sampling in replica exchange simulations of ordered and disordered proteins.

Recasting temperature replica exchange (T-RE) as a special case of Gibbs sampling has led to a simple and efficient scheme for enhanced mixing (Chodera and Shirts, J. Chem. Phys., 2011, 135, 194110). To critically examine if T-RE with independence sampling (T-REis) improves conformational sampling, we performed T-RE and T-REis simulations of ordered and disordered proteins using coarse-grained and atomistic models. The results demonstrate that T-REis effectively increase the replica mobility in temperatures space with minimal computational overhead, especially for folded proteins. However, enhanced mixing does not translate well into improved conformational sampling. The convergences of thermodynamic properties interested are similar, with slight improvements for T-REis of ordered systems. The study re-affirms the efficiency of T-RE does not appear to be limited by temperature diffusion, but by the inherent rates of spontaneous large-scale conformational re-arrangements. Due to its simplicity and efficacy of enhanced mixing, T-REis is expected to be more effective when incorporated with various Hamiltonian-RE protocols. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

Resident physicians' scores on the REI section of the CREOG exam are traditionally low, and nearly 40% of house staff nation-wide perceive their REI knowledge to be poor. We aimed to assess whether an interactive case-based group-learning curriculum would narrow the REI knowledge gap by improving understanding and retention of core REI concepts under the time constraints affecting residents. A three-hour case-based workshop was developed to address four primary CREOG objectives. A multiple-choice test was administered immediately before and after the intervention and 7 weeks post-workshop, to evaluate both knowledge and confidence. Following the intervention, residents self-reported increased confidence with counseling and treatment of PCOS, ovulation induction cycle monitoring, counseling and treatment of POI, and breaking bad news related to infertility (p < 0.05). The multiple-choice exam was re-administered 7 weeks post-intervention, and scores remained significantly improved compared to pre-workshop scores (p < 0.05). At that time, all residents either strongly agreed (91.7%) or agreed (8.3%) that the case-based interactive format was preferable to traditional lecture-based teaching. In conclusion, a nontraditional curriculum aimed at teaching core REI concepts to residents through interactive case-based learning can be successfully integrated into a residency curriculum, and significantly improves knowledge and confidence of critical concepts in REI.

Full Text Available The basic sanitation comprises several services that are essential to the maintenance of people's health and well-being. The populations that have an appropriate water supply, sewage collection and treatment, proper garbage disposal, among other services, are protected from diseases and have access to a minimum comfort to live in a safe way. In spite of the importance of these services, to the extent to be characterized as “basic”, several populations, national or worldwide, suffer for the lack or the complete privation of sanitation, live without access to quality water, their waste is thrown under open air and their garbage is disposed in inappropriate sites, what causes health and environmental impacts. This work is being accomplished in a community called Santa Cruz, located in Campos dos Goytacazes, RJ, and aims to carry out a survey about the local sanitary reality, especially about the quality of the water supplied to the population. 100 inhabitants of that community were interviewed and answered a questionnaire. Among the results, 22% of the interviewees consume the water that comes to their homes without any type of treatment, 47% consider the supply water as being of poor quality and 7% don't own home water tanks. After the interviews, bacteriological and physicochemical water analyses were performed in fifteen samples collected in the community. The test results indicated that the collected water was out of the drinking water standards, and therefore, inappropriate for human consumption.

Exercise stress (Ex) and redistribution (RD) myocardial tomography with Tl-201 has been widely used for evaluating myocardial viability. But recent studies have demonstrated that reinjection (ReI) study following RD study is necessary for detecting reversible ischemic myocardium. On the other hand, decreased myocardial washout of Tl-201 after Ex is an indicator of myocardial ischemia. So we have studied the usefulness of myocardial Tl-201 washout rate (WOR) for the evaluation of myocardial viability by comparing it with ReI images. Ex and RD myocardial tomographies were obtained immediately after Ex and 3 hours later. After RD study a small amount of Tl-201 was injected and ReI imaging was repeated. We studied 64 myocardial segments (in 58 patients with coronary artery disease) in which Ex-induced perfusion defects persisted in RD images. According to the changes of perfusion defects between Ex, RD and ReI images, they were classified into 3 types: Type I; perfusion defect on the RD image was identical to ReI image (75%). Type I was divided into 2 subgroups whether perfusion defect at Ex was unchanged (Ia, 42%) or improved (Ib, 33%) on the RD image. Type II; perfusion defect at Ex was reduced on the RD image and it improved furthermore at ReI image (17%). Type III; perfusion defect was the same at Ex and RD but it was reduced on the ReI image (8%). WOR less than 30% was defined as abnormal when Ex heart rate exceeded 120 bpm and lung-myocardial Tl-201 uptake ratio was less than 0.45. The differentiation between Type Ia and Type III is of great importance. History of myocardial infarction, effort angina and Ex induced ST depression could not differentiate these 2 groups. WOR abnormality was observed in all of Type III, but WOR was normal in Type Ia. In conclusion, WOR abnormality in Ex-RD myocardial imaging is useful for evaluating myocardial viability. ReI imaging is necessary for the precise evaluation of viable muscle mass and for inadequate Ex. (author)

Full Text Available Restraint and cold stress increase both corticosterone and glycemia, which lead to oxidative damages in hepatic tissue. This study assessed the effect of royal jelly (RJ supplementation on the corticosterone level, glycemia, plasma enzymes and hepatic antioxidant system in restraint and cold stressed rats. Wistar rats were allocated into no-stress, stress, no-stress supplemented with RJ and stress supplemented with RJ groups. Initially, RJ (200mg/Kg was administered for fourteen days and stressed groups were submitted to chronic stress from the seventh day. The results showed that RJ supplementation decreases corticosterone levels and improves glycemia control after stress induction. RJ supplementation also decreased the body weight, AST, ALP and GGT. Moreover, RJ improved total antioxidant capacity, SOD activity and reduced GSH, GR and lipoperoxidation in the liver. Thus, RJ supplementation reestablished the corticosterone levels and the hepatic antioxidant system in stressed rats, indicating an adaptogenic and hepatoprotective potential of RJ.

Royal jelly (RJ) is a honeybee product containing proteins, carbohydrates, fats, free amino acids, vitamins, and minerals. As its principal unsaturated fatty acid, RJ contains 10-hydroxy-2-decenoic acid (10-HDA), which may have antitumor and antibacterial activity and a capacity to stimulate collagen production. RJ has attracted interest in various parts of the world for its pharmacological properties. However, the effects of RJ on ultraviolet (UV)-induced photoaging of the skin have not been reported. In this study we measured the 10-HDA content of RJ by high-performance liquid chromatography and tested the effects of RJ on UVB-induced skin photoaging in normal human dermal fibroblasts. The effects of RJ and 10-HDA on UVB-induced photoaging were tested by measuring procollagen type I, transforming growth factor (TGF)-β1, and matrix metalloproteinase (MMP)-1 after UVB irradiation. The RJ contained about 0.211% 10-HDA. The UVB-irradiated human skin fibroblasts treated with RJ and 10-HDA had increased procollagen type I and TGF-β1 productions, but the level of MMP-1 was not changed. Thus RJ may potentially protect the skin from UVB-induced photoaging by enhancing collagen production.

Reproductive endocrinology and infertility (REI) is one of the original officially recognized subspecialties in obstetrics and gynecology and among the earlier subspecialties in medicine. Recognized by the American Board of Obstetrics and Gynecology in 1972, fellowship programs are now 3 years in length following an obstetrics and gynecology residency. Originally focused on endocrine problems related to reproductive function, the assisted reproductive technologies (ART) have recently become the larger part of training during REI fellowships. It is likely that the subspecialty of REI strengthens the specialty of obstetrics and gynecology and enhances the educational experience of residents in the field. The value of training and certification in REI is most evident in the remarkable and consistent improvement in the success of ART procedures, particularly in vitro fertilization. The requirement for documented research activity during REI fellowships is likely to stimulate a more rapid adoption (translation) of newer research findings into clinical care after training. Although mandatory reporting of outcomes has been proposed as a reason for this improvement the rapid translation of reproductive research into clinical practice is likely to be a major cause. Looking forward, REI training should emphasize and strengthen education and research into the endocrine, environmental, and genetic aspects of female and male reproduction to improve the reproductive health and fertility of all women.

Full Text Available Jabuticaba (Myrciariasp is a fruit native to the Atlantic Forest, belonging to the Myrtaceae family, and commonly found in Brazil. It presents considerable economic potential because it can be consumed as raw fruit or processed food. In Varre-Sai, RJ, jabuticaba is strongly used in the industrialization of alcoholic beverages. The production of fermented alcoholic alternative is used to avoid waste, and make the most of the considerable nutritional value of the fruit. The content of anthocyanins in jabuticaba ranges from 310 and 315mg/100g, relatively high value compared to other fruits considered rich in antioxidants. Therefore, sensory analyses of jabuticaba alcoholic beverages produced in Varre-Sai can improve the quality of the product and potential sales. Given that the part of jabuticaba rich in phenolic compounds is the bark, the whole use of the fruit is the best alternative to take advantage of its benefits. Sensory analysis evaluated the acceptance of fermented alcoholic of Jabuticaba, in relation to its overall rating attributes, color, flavor and aroma, based on a 9-point hedonic scale, with ends named strongly disliked (1 and strongly liked (9; as well as purchase intention of tasters by a 5-point hedonic scale, with anchor points would certainly buy (5 and would not certainly buy (1. The results showed that the products had good acceptance and the fermented Sweet Tinto was rated best in all attributes, obtaining 90.18% frequency in the acceptance of hedonic scale, with respect to global acceptance. Even in the hypothetical situation of purchase, it received 74.5% of the votes in the good range of the scale. This shows that the alcoholic fermented beverages may be an alternative for the consumption of antioxidants, and that their production can improve the income of farmers as well as help avoid fruit wasting.

Este trabalho objetivou avaliar a riqueza e abundância da fauna edáfica, bem como sua distribuição vertical, em área de restinga periodicamente inundada na Ilha da Marambaia, RJ, em duas épocas distintas, verão (chuvosa e inverno (seca. Foram coletadas 10 amostras de serapilheira e de solo na profundidade de 0-5 cm, em que foram feitas extrações da fauna por meio de extratores do tipo Berlese-Tüllgren. Observou-se aumento da abundância da fauna edáfica do período seco para o chuvoso, enquanto a riqueza de grupos taxonômicos não foi modificada. Em ambas as épocas, os grupos de maior ocorrência foram Formicidae e Collembola. Quanto à distribuição vertical, verificou-se a preferência dos organismos pelo compartimento serapilheira, no período chuvoso, e pelo solo, no período seco. A microfagia e a saprofagia representaram as principais formas de utilização dos recursos alimentares, seguidos da predação, sugerindo melhor estruturação do habitat no ecossistema. Além disso, a ocorrência de grupos que só são percebidos em ambientes não perturbados indica que o ecossistema de restinga da Ilha da Marambaia, no momento em que foi avaliado, ano de 2002, encontrava-se pouco ou nada degradado e em bom estado de conservação.

Para isso, gerou-se inicialmente o Modelo Digital de Elevação Hidrologicamente Consistente (MDEHC a partir de cartas topográficas do IBGE, na escala 1:50.000, utilizando o sistema de informações geográficas, através dos softwares ArcVIEW e Arc/INFO. A partir do MDEHC, foram calculados alguns parâmetros morfométricos para o estudo do comportamento hidrológico da bacia. A área de drenagem encontrada foi de 9,9156 km² e o perímetro, de 17,684 km. A bacia hidrográfica do rio Debossan tem formato alongado, coeficiente de compacidade de 1,5842, fator de forma de 0,3285 e índice de circularidade de 0,3985. A densidade de drenagem obtida para a bacia foi de 2,3579 km/km². A forma mais alongada da bacia hidrográfica indica que a precipitação pluviométrica sobre ela se concentra em diferentes pontos, concorrendo para amenizar a influência da intensidade de chuvas, as quais poderiam causar maiores variações da vazão do curso d'água.The objective of this work was to perform a morphometric characterization based on some physical parameters. In order to do so, a Hydrologically Consistent Digital Elevation Model (HCDEM was generated from IBGE topographical maps, scale 1:50.000, using as database and analysis the system of geographic information, by means of the ArcVIEW and Arc/INFO version 8.3 systems. From this, some morphometric parameters of a previous study on the hydrologic behavior of the watershed were calculated. The drainage area was 9,9156 Km² and 17,684 km in perimeter. The Debossan river watershed was proven not easily subject to floods as the compacity coefficient was far from the unit (1.5842 and its shape factor presented a low value (0.3285. Such fact can still be proven by the circularity index value (0.3985. The drainage density was 2,3579 Km

Impact of aerosols on ice crystal size

Directory of Open Access Journals (Sweden)

B. Zhao

2018-01-01

Full Text Available The interactions between aerosols and ice clouds represent one of the largest uncertainties in global radiative forcing from pre-industrial time to the present. In particular, the impact of aerosols on ice crystal effective radius (Rei, which is a key parameter determining ice clouds' net radiative effect, is highly uncertain due to limited and conflicting observational evidence. Here we investigate the effects of aerosols on Rei under different meteorological conditions using 9-year satellite observations. We find that the responses of Rei to aerosol loadings are modulated by water vapor amount in conjunction with several other meteorological parameters. While there is a significant negative correlation between Rei and aerosol loading in moist conditions, consistent with the "Twomey effect" for liquid clouds, a strong positive correlation between the two occurs in dry conditions. Simulations based on a cloud parcel model suggest that water vapor modulates the relative importance of different ice nucleation modes, leading to the opposite aerosol impacts between moist and dry conditions. When ice clouds are decomposed into those generated from deep convection and formed in situ, the water vapor modulation remains in effect for both ice cloud types, although the sensitivities of Rei to aerosols differ noticeably between them due to distinct formation mechanisms. The water vapor modulation can largely explain the difference in the responses of Rei to aerosol loadings in various seasons. A proper representation of the water vapor modulation is essential for an accurate estimate of aerosol–cloud radiative forcing produced by ice clouds.

Objective. To determine if student pharmacists' preferences towards experiential and rational thinking are associated with performance on advanced pharmacy practice experiences (APPEs) and whether thinking style preference changes following APPEs. Methods. The Rational Experiential Inventory (REI), a validated survey of thinking style, was administered to student pharmacists before starting APPEs and re-administered after completing APPEs. APPE grades were compared to initial REI scores. Results. Rational Experiential Inventory scores remained consistent before and after APPEs. Overall, APPE grades were independent of REI scores. In a regression model, the REI experiential score was a significant negative predictor of hospital APPE grades. Conclusion. These findings suggest that overall APPE performance is independent of decision-making preference, and decision-making style does not change following immersion into APPEs. Instead of targeting teaching strategies towards a specific decision-making style, preceptors may use pedagogical approaches that promote sound clinical decision-making skills through critical thinking and reflection.

To analyze the use of Spanish language translation on the websites of reproductive endocrinology and infertility (REI) practices in the context of evidence of underuse of infertility services by minority populations. Cross-sectional survey of websites from REI practices. Not applicable. None. None. Assessment of the relationship between having a Spanish-translated website and REI practice characteristics. Variables included concurrent use of social media, size of the practice, Spanish-speaking practitioner in the practice, being a private or a university-based practice, being in a mandated insurance state, and being in an area with different levels of percentage of Hispanic population, adjusted for annual income levels of the population. Of the 376 REI practice websites analyzed, 101 (27%) offered at least some information in Spanish. We identified 97 Spanish-speaking practitioners at 71 REI practices. Having a Spanish-translated website was significantly associated with the practice's use of social media, having an international/out-of-town web page, and having a Spanish-speaking physician in the practice. The size of the practice, as measured in number of cycles reported per year, was not associated with having a translated website. In practices located in the top 60 metropolitan areas by Hispanic population, the odds of having a Spanish-translated website were only related to the percentage of Hispanic population after adjusting for state-mandated insurance and average annual income level of the Hispanic population. Sixty-six of the websites with Spanish-translated content had been automatically translated. An additional eight websites were partially translated automatically. REI practices in metropolitan areas with a higher percentage of Hispanics were more likely to reach out to this minority population by translating their website content into Spanish. These practices were also more likely to use social media. Future studies are needed to determine whether

Maywood Chemical Works (MCW) of Maywood, New Jersey, generated process wastes and residues associated with the production and refining of thorium and thorium compounds from monazite ores from 1916 to 1956. MCW supplied rare earth metals and thorium compounds to the Atomic Energy Commission and various other government agencies from the late 1940s to the mid-1950s. Area residents used the sandlike waste from this thorium extraction process mixed with tea and cocoa leaves as mulch in their yards. Some of these contaminated wastes were also eroded from the site into Lodi Brook. At the request of the US Department of Energy (DOE), a group from Oak Ridge National Laboratory conducts investigative radiological surveys of properties in the vicinity of MCW to determine whether a property is contaminated with radioactive residues, principally 232 Th, derived from the MCW site. The surveys typically include direct measurement of gamma radiation levels and soil sampling for radionuclide analyses. The survey of this commercial property at Route 17(S) and Becker Avenue, Rochelle Park, New Jersey (RJ001), was conducted in 1986. Measurements taken at the commercial property located at Route 17(S) and Becker Avenue indicate slightly elevated gamma exposure rates in three areas of the parking lot. Although results of analysis of the asphalt disclosed radionuclide concentrations in excess of the applicable criterion, their presence is due to naturally radioactive substances in asphalt patching materials and is not associated with material from the MCW site. Therefore, it is recommended that this site be eliminated from consideration for inclusion in the DOE remedial action program. 5 refs., 2 figs., 3 tabs

Full Text Available Análise do comportamento empreendedor de Irineu Evangelista de Sousa, observado no filme "Mauá - O Imperador e o Rei". Procurou-se usar como base argumentativa o trabalho de Louis Jacques Filion (2004, 2000, 1993, 1991 sobre características empreendedoras básicas - inovação, aprendizagem, rede de relações e visão. A escolha do tema deveu-se ao pouco conhecimento dos alunos de graduação e pós-graduação em administração - detectado em uma pesquisa exploratória informal - sobre os empreendedores brasileiros e seu papel na evolução econômica do país, sendo relevante este resgate histórico. Após cinco exibições coletivas e algumas exibições individuais do filme, foi realizado um estudo observacional, tipo de observação de "segunda mão", indireta e não participante, com produtivas discussões em equipe. Na revisão bibliográfica buscou-se contextualizar, de maneira sucinta, as características do comportamento empreendedor da ótica de Filion (1991. Pode-se concluir que as características empreendedoras propostas na tipologia do autor apresentam-se com vigor no comportamento do Barão de Mauá, um homem à frente de seu tempo e que procurou contribuir na construção de um novo projeto para o Brasil, possibilitando a transição de um modelo econômico agrário exportador e escravocrata para uma economia de mercado baseada na industrialização, no trabalho assalariado e na livre iniciativa, sendo esse conhecimento essencial para o desenvolvimento do senso crítico e analítico do aluno.

Pooled semen were diluted with soybean lecithin-based extender without RJ (control) or supplemented with different concentrations (0.25, 0.5 and 0.75%) of RJ (RJ0.25, RJ0.5, RJ0.75 respectively), at a final concentration of 150 × 10 6 spermatozoon/mL. Semen samples were assessed for sperm motility, plasma membrane integrity using hypoosmotic swelling test (HOST) damaged acrosome using FITC-Pisum sativum agglutinin (PSA-FITC) and DNA integrity using terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling (TUNEL). The addition of RJ (0.5%, 0.75%) led to higher percentages of subjective motilities (55.33 ± 2.29%, 57.67 ± 2.58%) compared to control and RJ0.25 groups (49.00 ± 2,80%, 51.67 ± 3.09%) (P  0.05). In the end of incubation, motility and HOST rates of RJ0.5 (14.00 ± 3.87%, 31.20 ± 3.70%) and RJ0.75 (15.00 ± 3.27%, 29.20 ± 2.59%) groups were higher than control (8.00 ± 2.54%, 18.20 ± 3.11%) and RJ0.25 (9.00 ± 2.07%, 20.60 ± 2.88%) groups (P < 0.05). Also defected acrosome and DNA fragmation rates of RJ0.5 (32.20 ± 1.30%, 5.4 ± 0.55%) and RJ0.75 (29.20 ± 1.30%, 5.80 ± 0.45%) groups were significantly lower than control (38.80 ± 0.84%, 7.40 ± 1.34%) and RJ0.25 (39.80 ± 2.05%, 7.00 ± 1.58) groups. This study shows that RJ supplemented extenders have beneficial effect on goat sperm parameters at 0 h and 6 h of incubation. Copyright © 2016 Elsevier Inc. All rights reserved.

Full Text Available Leishmania RNA virus (LRV has been shown to be a symbiotic component of Leishmania parasites in South America. Nested retro-transcription polymerase chain reaction was employed to investigate LRV1 presence in leishmaniasis lesions from Brazil. In endemic areas of Rio de Janeiro (RJ, no LRV1 infection was observed even with mucosal involvement. LRV1 was only detected in Leishmania (V. guyanensis cutaneous lesions from the northern region, which were obtained from patients presenting with disease reactivation after clinical cure of their primary lesions. Our results indicated that the severity of leishmaniasis in some areas of RJ, where Leishmania (V. brazi-liensis is the primary etiological agent, was not associated with Leishmania LRV1 infection.

Full Text Available This article presents a case study about the Polo Universitário de Volta Redonda (PUVR-UFF, a new campus of Federal Fluminense University (UFF, located in the Médio Paraíba Fluminense Region (RMP-RJ. The aim is to identify the limits and possibilities of contribution of a public university for innovation and regional development. The theoretical framework is based on the concept of entrepreneurial university. We conducted a qualitative study with 5 managers of the central structure of UFF (UFF-Sede and 14 managers and researchers of PUVR-UFF. The mains results indicate that are incipient efforts undertaken by PUVR-UFF to stimulate innovative activities among its faculty, as well as actions that stimulate regional development. Interviewees perceived that the major barriers of PUVR-UFF are related to the improvement of bureaucratic processes of the university, the expanding the work with the society and the establishment of mechanisms to encourage the transformation of basic research in technology and innovation. The survey data also indicate the importance of academic leaders capable of mobilizing the university in conducting activities of interaction with society, encouraging an entrepreneurial university.

Potential bird dispersers of Psychotria in a area of Atlantic forest on Ilha Grande, RJ, Southeastern Brazil: a biochemical analysis of the fruits

Directory of Open Access Journals (Sweden)

E. M. Almeida

Full Text Available The present study assessed the fruiting pattern, bird foraging behavior, and sugar content of ripe fruits of two sympatric species of Rubiaceae (Psychotria brasiliensis and P. nuda. This study was carried out in an Atlantic forest area on Ilha Grande, RJ, between August 1998 and July 1999. Fruit production occurred year round, with a peak of mature P. brasiliensis fruits in December 1998 and another of P. nuda in February of 1999. Lipaugus lanioides (Cotingidae, Baryphtengus ruficapillus (Momotidae and Saltator similis (Emberizidae made the most frequent foraging visits to fruiting P. brasiliensis, so that L. lanioides and B. ruficapillus removed the fruits with sallying maneuvers while S. similis gleaned the fruits. Lipaugus lanioides was by far the most important consumer, and potentially the main disperser of P. brasiliensis. Birds of this genus are heavy frugivores in the tropical forests and are widely assumed to be important seed dispersers. The fruits were analyzed quantitatively and qualitatively in relation to the amounts of sucrose and starch. Psychotria brasiliensis (the visited species showed the smallest quantity of sucrose and the highest amount of starch. These findings suggest that what may influence the birds' choice of fruit is the proportion of starch in the Psychotria species studied here rather than the carbohydrate composition.

Full Text Available O objetivo deste trabalho foi caracterizar o comportamento hidrológico, o volume de entrada e saída de água da bacia hidrográfica do rio Debossan, onde se localiza uma importante estação de captação de água, administrada pela Concessionária de Águas e Esgotos de Nova Friburgo LTDA. (CAENF, inserida na Reserva Ecológica de Macaé de Cima, Município de Nova Friburgo, Rio de Janeiro. Para isso, foram obtidos dados de vazão e precipitação diários do período de janeiro de 2002 a dezembro de 2004. A partir desses dados, foram calculados alguns parâmetros hidrológicos, como vazão específica e deflúvio. A precipitação média observada nos três anos foi de 2.163 mm, sendo que os meses de dezembro/2002 e janeiro/2003 apresentaram os máximos valores. A vazão média anual no período foi de 0,86 m³/s, apresentando o mês de dezembro de 2002 com maior índice e setembro de 2004 com o menor. O balanço hídrico, em termos médios anuais nos três anos de medições, apresentou uma evapotranspiração de 1.923,04 mm, equivalendo a 88% da precipitação convencional. Pode-se dizer que o ecossistema florestal exerce efeito tamponante sobre a quantidade de água da bacia hidrográfica, mantendo uma grande vazão nos meses de menor pluviosidade. Ao analisar a relação entre a entrada de água na bacia, o uso atual do solo e a quantidade de água produzida, concluiu-se que uma bacia hidrográfica bem preservada tem fundamental importância na manutenção constante da vazão ao longo do ano, além da visível participação na qualidade da água.The objective of this work was to characterize the hydrological behavior and the volume of water entering and leaving the Debossan river watershed, where an important water captation plant is situated, managed by the Nova Friburgo Water and Sewage Treatment Company LTDA (CAENF, within the 'Macaé de Cima' Ecological Reserve, Nova Friburgo-RJ.

Our goal is to contribute to future modeling of local trophic dynamics. Subsurface water samples were taken weekly during the year 2000 at two sites: Urca (close to the entrance, more saline, eutrophic and Ramos (inner area, less saline, hypertrophic. Microscopic analysis was done by epifluorescence and cell density was converted to biomass through cell biovolume. Total nanoplankton was about 10(8 cells.l-1 in most samples (>57%, and total filamentous bacteria densities varied from 10(5 to 10(8 fil.l-1. Autotroph density was one order of magnitude higher at Ramos, both for nanoplankton (Md: 10(8cells.l-1 at Ramos and 10(7cells.l-1 at Urca and for filamentous bacteria (Md: 10(6 fil.l-1 at Ramos and 10(5 fil.l-1 at Urca.

Full Text Available Resilience, as a property of social-ecological systems, is related to the ability of such systems to adapt and deal with perturbations. This study examined the characteristics in a community of artisanal fishermen, using some of the resilience indicators (flexibility, capacity to organize and capacity to learn. The flexibility indicator represents the economic dependence on the natural resource; the capacity to organize indicator informs about participation in decision-making and in community organizations; and the capacity to learn indicator refers to the perception of environmental alterations in relation to human activity. Together, these indicators can inform about the adaptive capacity of the community and its relationship with resource management. Semi structured interviews were conducted in the months of January, April, July and August of 2012 in the community of Praia Grande and surroundings (Paraty/RJ (n=22. As to the flexibility indicator, 59.1% of the fishermen interviewed have another source of income, being tourism the main activity among them (36.4%. Most of the fishermen (77.2% use more than one type of fishing technique which may either reduce pressure on the fishing resource or have an opposite effect, if it is the case of the use of more intensive techniques, such as trawling. Regarding the fishermen’s capacity to organize, it was found and discussed the low participation on decision-making regarding fishing, especially because the area of the study is situated in a context of social-environmental conflicts with conservation areas. As for the capacity to learn, the results indicate that the fishermen perceive the human activity as an agent responsible for the perturbations in the natural environment, and they suggest different solutions in face of the decrease of each target species. Through the use of the resilience indicators it was possible to identify the attributes that allow the adaptation of the community to

Experiments on radionuclide accumulation by fishes from the Angra Dos Reis region of Brazil

To follow the bioaccumulation and tissue distribution of 137 Cs and 60 Co in fish from tropical waters near the Angra nuclear power station in Brazil, juvenile grouper (Epinephelus sp.) were exposed under laboratory conditions to Angra sea water containing the two radionuclides initially added in chloride form. During the 4-month exposure period, the sea water was not changed and the fish received regular rations of non-radioactive food. Following uptake, the fish were dissected and composite tissue samples monitored for radioactivity. 137 Cs concentration factors (CFs) were 3 and 5 in whole fish and muscle, respectively. The highest concentration of 137 Cs was found in the muscle which accounted for 66% of the total body burden. In contrast, the highest concentration and greatest fraction (19%) of 60 Co was located in the liver. Whole body and muscle CFs for 60 Co, 0.2 and 0.08 respectively, were much lower than those for 137 Cs. Compared with published data, only very small amounts of both radionuclides were taken up by bone in the present study. This observation and the fact that much higher 137 Cs CFs have been reported in fish from field studies suggests that uptake through the food chain is the principal pathway for bioaccumulation in nature. Elution of freshly-prepared and previously-used radioactive sea water through chelating resins indicated that 60 Co added in the cationic form was almost totally converted to neutral or anionic forms after four months. Additional experiments carried out with the previously-used experimental media demonstrated that the possibly ligand-bound 60 Co was approximately 2.5 times more available for uptake by grouper than the cationic forms initially present. It is concluded that the uptake of 60 Co by fish exposed to radioactive effluents would be a function of the different forms of 60 Co present. 20 refs, 2 figs, 2 tabs

Full Text Available The alternative use of natural products, like royal jelly (RJ, may be an important tool for the treatment of infections caused by antibiotic-resistant bacteria. RJ presents a large number of bioactive substances, including antimicrobial compounds. In this study, we carried out the chemical characterization of fresh and lyophilized RJ and investigated their antibacterial effects with the purpose of evaluating if the lyophilization process maintains the chemical and antibacterial properties of RJ. Furthermore, we evaluated the antibacterial efficacy of the main fatty acid found in RJ, the 10-hydroxy-2-decenoic acid (10H2DA. Chromatographic profile of the RJ samples showed similar fingerprints and the presence of 10H2DA in both samples. Furthermore, fresh and lyophilized RJ were effective against all bacteria evaluated; that is, the lyophilization process maintains the antibacterial activity of RJ and the chemical field of 10H2DA. The fatty acid 10H2DA exhibited a good antibacterial activity against Streptococcus pneumoniae. Therefore, it may be used as an alternative and complementary treatment for infections caused by antibiotic-resistant S. pneumoniae.

The paullon chalcone derivative KuRei300 is active against Leishmania donovani, the protozoans causing visceral leishmaniasis. The aim of this study was the development of a parenteral formulation of the virtually water insoluble compound in order to enable future studies in mice. Mixed lecithin/bile salt micelles, liposomes, supercooled smectic cholesterol myristate nanoparticles, cubic phase nanoparticles and a triglyceride emulsion were screened for their solubilizing properties. Due to the limited available amount of KuRei300 a passive loading approach with pre-formulated carriers that were incubated with drug substance deposited onto the walls of glass vials was used. The loading capacities of the nanocarriers, the influence of the solid state properties of the drug and its deposits on the loading results and chemical stability aspects of KuRei300 were investigated. Employed methods included HPLC, UV spectroscopy, (1)H NMR, XRPD, and DSC. All nanocarriers substantially improved the solubility of KuRei300; the mixed micelles exhibited the highest drug load. Related to the lipid matrix, however, the smectic nanoparticles solubilized the significantly highest amount of drug. Loading from physically altered drug deposits improved the obtainable concentration to the threefold compared with untreated drug powder. Formulations with KuRei300 must be stored excluded from light under a nitrogen atmosphere as the substance is susceptible to photoisomerization and decomposition. Copyright © 2013 Elsevier B.V.

We have merged a set of physics-based and empirical models to investigate the energy and spatial distributions of Jupiter's electron and proton populations in the inner and middle magnetospheric regions. Beyond the main source of plasma (> 5 Rj) where interchange instability is believed to drive the radial transport of charged particles, the method originally developed by Divine and Garrett [J. Geophys. Res., 88, 6889-6903, 1983] has been adapted. Closer to the planet where field fluctuations control the radial transport, a diffusion theory approach is used. Our results for the equatorial and mid-latitude regions are compared with Pioneer and Galileo Probe measurements. Data collected along Juno's polar orbit allow us to examine the features of Jupiter's radiation environment near the inner boundary of trapping regions. Significant discrepancies between Juno (JEDI keV energy particles and high energy radiation environment measurements made by Juno's SRU and ASC star cameras and the JIRAM infrared imager) and Galileo Probe data sets and models are observed close to the planet. Our simulations of Juno MWR observations of Jupiter's electron-belt emission confirm the limitation of our model to realistically depict the energy and spatial distributions of the ultra-energetic electrons. In this paper, we present our modeling approach, the data sets and resulting data-model comparisons for Juno's first science orbits. We describe our effort to improve our models of electron and proton belts. To gain a physical understanding of the dissimilarities with observations, we revisit the magnetic environment and the mechanisms of loss and source in our models.

1988-01-01

A broard research program on radionuclides became necessary due to the construction of the Nuclear Power Plant at Angra dos Reis. As part of this program the research developped by the Marine Biology Departament, UFRJ, aimed at estimating the radiation doses to wich the population of the region might be exposed and to determine biological indicators to radioactive contamination. Up to the present moment, the bioacumulation factors (BFs) of 60 Co, 137 Cs and 131 I by ''clam'' (Anomalocardia brasiliana) and the biological half-life of cobalt and cesium in this animal were determined, as well as the B.F. of 85 Sr by ''snail'' (Strombus pugilis) and by ''barnacle'' (Megabalanus tintinnabulum). The remobilization of 60 Co by microbiological activity in marine sediment was also studied. These studies were made using the standard methodology for bioaccumulation and elimination in closed water systems. The results showed an important microbiological activity in the remobilization of elements in the sediment. Due to the low bioaccumulation factors obtained the studied organisms were not considered ideal biological indicators for radioactive pollution. However, their importance as edible animals in the Angra dos Reis region recommends their radiometry for routine radiological monitoring. Studies on other organisms and/or radionuclides are now in progress at the Marine Biology Departament (UFRJ). (author) [pt

Influence of the solar wind and IMF on Jupiter's magnetosphere: Results from global MHD simulations

Science.gov (United States)

Sarkango, Y.; Jia, X.; Toth, G.; Hansen, K. C.

2017-12-01

Due to its large size, rapid rotation and presence of substantial internal plasma sources, Jupiter's magnetosphere is fundamentally different from that of the Earth. How and to what extent do the external factors, such as the solar wind and interplanetary magnetic field (IMF), influence the internally-driven magnetosphere is an open question. In this work, we solve the 3D semi-relativistic magnetohydrodynamic (MHD) equations using a well-established code, BATSRUS, to model the Jovian magnetosphere and study its interaction with the solar wind. Our global model adopts a non-uniform mesh covering the region from 200 RJ upstream to 1800 RJ downstream with the inner boundary placed at a radial distance of 2.5 RJ. The Io plasma torus centered around 6 RJ is generated in our model through appropriate mass-loading terms added to the set of MHD equations. We perform systematic numerical experiments in which we vary the upstream solar wind properties to investigate the impact of solar wind events, such as interplanetary shock and IMF rotation, on the global magnetosphere. From our simulations, we extract the location of the magnetopause boundary, the bow shock and the open-closed field line boundary (OCB), and determine their dependence on the solar wind properties and the IMF orientation. For validation, we compare our simulation results, such as density, temperature and magnetic field, to published empirical models based on in-situ measurements.

Full Text Available Within the scope of the MAR-14 Project, part of the Brazil-Germany Bilateral Agreement in Marine Sciences, an oceanographic survey aboard the R/V Victor Hensen was carried out in Brazilian coastal waters between Santos (23º56'S and Rio de Janeiro (22º54'S, from January 15 to January 22,1991. In this article we report results of preliminary analyses of the hydrographic data collected with CTD, STD, Nansen bottles and XBT's. These preliminary results show intense stratification in the first 200 m depth, and the penetration of the Brazil Current deep into the continental shelf region. Two eddy-like features were detected. The first one, anticyclonic, was located in the northern part of the domain and confined to the uppermost 200 m. The second, a cyclonic vortex, was found a little to the southwest below 200 m and extending downwards to about 800 m depth. Water mass analyses based on T-S diagrams suggest that the interface between the South Atlantic Central Water (SACW and the Antarctic Intermediate Water (AIW is located at about 500 m depth. One important aspect of this study is that this was the first time a high resolution survey with a CTD probe was realized along the eastern Brasilian Coast, south of Cabo Frio.Como parte do projeto MAR-14, componente do Acordo Bilateral Brasil-Alemanha em Ciências Marinhas, uma campanha oceanógrafica a bordo do R/V Victor Hensen foi realizada em águas costeiras do Brasil entre Santos (23º56'S, de 15 a 22 de janeiro de 991.

2017-01-01

The first goal of this study was to validate the Rational-Experiential Inventory ( REI ) and the Cognitive Reflection Test ( CRT ) through checking their relation to the transitivity axiom. The second goal was to test the relation between decision strategies and cognitive style as well as the relation between decision strategies and the transitivity of preferences. The following characteristics of strategies were investigated: requirements for trade-offs, maximization vs. satisficing and option-wise vs. attribute-wise information processing. Respondents were given choices between two multi-attribute options. The options were designed so that the choice indicated which strategy was applied. Both the REI-R and the CRT were found to be good predictors of the transitivity of preferences. Respondents who applied compensatory strategies and the maximization criterion scored highly on the REI-R and in the CRT , whereas those who applied the satisficing rule scored highly on the REI-R but not in the CRT . Attribute-wise information processing was related to low scores in both measurements. Option-wise information processing led to a high transitivity of preferences.

Polonium-210 ( 210 Po), a short-lived member from the uranium series, is broadly distributed in Nature being among all alpha-emitters the major contributor to the internal dose in man. Studies of diets have shown that marine foods are important sources of this radionuclide. The levels of 210 Po have been determined in three highly consumed marine species, the fishes Sardinella brasiliensis (sardine) and Thunnus atlanticus (tuna), and the shrimp Litopenaeus brasiliensis, purchased from the Niteroi (RJ, Brazil) fish market, and caught along the coast of the state of Rio de Janeiro. Doses of 210 Po were determined for the entire organisms and for some tissues and organs, such as eyes, heart, gills, muscle, stomach liver, intestine and pyloric caecal (fishes) or eyes, head content, exoskeleton, muscle, hepatopancreas and pleopods. 210 Po is not uniformly distributed within these species, the highest levels being observed for sardine in the intestine (1634.6 mBq g-1), tuna in pyloric caecal (4656.1 mBq g-1) and shrimp in the hepatopancreas (1460.5 mBq g-1). The 210 Po activities in sardine, tuna and shrimp, calculated on a mean whole-organism basis, were 64.6, 34.5 and 39.5 Bq kg-1 (dry weight) respectively, with corresponding concentration factors of 7.2 x104, 3.8 x104 and 4.4 x104. Considering body distribution, almost 60% of the total activity is concentrated in the pyloric caecal of both fishes and in the hepatopancreas of the shrimp. In turn, the edible parts concentrate much less activity. (author)

Full Text Available Abstract Background: Phenylhydrazine (PHZ as a strong oxidant agent causes variety of toxic effects including alterations in the biochemical and cardiac tissue. The aim of the present study was to investigate the effects of royal jelly (RJ and vitamin C (vit C against PHZ-induced cardiotoxicity in mice. Materials and Methods: Adult male mice were randomly assigned to eight groups of eight mice each. PHZ was administered to four groups of mice at a dose of 60 mg/kg per 48 hours intraperitoneally for 35 days. Three of these groups received vit C (250 mg/kg per day intraperitoneally, RJ (100 mg/kg per day orally and vit C+RJ with same doses four hours before PHZ administration, respectively. A vehicle-treated control group and vit C, RJ and vit C+RJ control groups were also included. Results: RJ and vit C significantly decreased (p< 0.05 the serum level of malondialdehyde and creatine kinase (CK-BM that had been increased by PHZ. Also, RJ and vit C increased the total antioxidant capacity and supraxoid dismutase serum that had been decreased by induced PHZ. Moreover, RJ and vit C could improve the tissue damages induced by PHZ such as diffused edema, hemorrhage, congestion, hyaline exudates, necrosis and also fibrosis tissue in heart tissue. Conclusion: It seems that Vit C and RJ can minimize PHZ-induced cardiotoxicity in mouse through oxidative reactions inhibition.

Queens consume royal jelly (RJ as the main food throughout their life, including as adults, but workers only eat worker jelly when they are larvae less than 3 days old. In order to explore the effect of RJ and the components affecting longevity of worker honey bees, we first determined the optimal dose for prolonging longevity of workers as 4% RJ in 50% sucrose solution, and developed a method of obtaining long lived workers. We then compared the effects of longevity extension by RJ 4% with bee-collected pollen from rapeseed (Brassica napus. Lastly, we determined that a water soluble RJ protein obtained by precipitation with 60% ammonium sulfate (RJP60 contained the main component for longevity extension after comparing the effects of RJ crude protein extract (RJCP, RJP30 (obtained by precipitation with 30% ammonium sulfate, and RJ ethanol extract (RJEE. Understanding what regulates worker longevity has potential to help increase colony productivity and improve crop pollination efficiency.

The Effects of Royal Jelly on Fitness Traits and Gene Expression in Drosophila melanogaster.

Directory of Open Access Journals (Sweden)

John R Shorter

Full Text Available Royal Jelly (RJ is a product made by honey bee workers and is required for queen differentiation and accompanying changes in queen body size, development time, lifespan and reproductive output relative to workers. Previous studies have reported similar changes in Drosophila melanogaster in response to RJ. Here, we quantified viability, development time, body size, productivity, lifespan and genome wide transcript abundance of D. melanogaster reared on standard culture medium supplemented with increasing concentrations of RJ. We found that lower concentrations of RJ do induce significant differences in body size in both sexes; higher concentrations reduce size, increase mortality, shorten lifespan and reduce productivity. Increased concentrations of RJ also consistently lengthened development time in both sexes. RJ is associated with changes in expression of 1,581 probe sets assessed using Affymetrix Drosophila 2.0 microarrays, which were enriched for genes associated with metabolism and amino acid degradation. The transcriptional changes are consistent with alterations in cellular processes to cope with excess nutrients provided by RJ, including biosynthesis and detoxification, which might contribute to accelerated senescence and reduced lifespan.

Terrestrial Magnetism in Ottoman Empire: Documents and Measurements

Ozcep, Ferhat

2016-04-01

In the modern sense, geophysics started with geomagnetic works in the 1600s in Ottoman geography. The period between 1600 and 1800 includes the measurement of magnetic declination, inclination and magnetic field strength. Before these years, there is a little information, such as how to use a compass, in the Kitab-i Bahriye (the Book of Navigation) of Piri Reis, who is one of the most important mariners of the Ottoman Empire. However, this may not mean that magnetic declination was generally understood. The first Turkish scientific book relating to terrestrial magnetism is the book of Fuyuzat-i Miknatissiye that was translated by Ibrahim Müteferrika and printed in 1731. The subject of this book is earth's magnetism. Magnetic compass was mentioned in several books. These areMuhammed al Awfi's "Jami al- Hikayat" (translated into Turkish by Ibn Arabşah); Piri Reis's Kitab-I Bahriye (The Book of "Navigation" or "Seafaring" or "Sea"); Seydi Ali Reis's "Risale-i Mirat-I Kainat min Alat-I Irtifa" (The Treatise called the Mirror of Universe according to the instrument for measuring Altitude) and Kitab Al-"Muhit" Fi˙Ilm'al-Eflak Va'l Abhur (Book of the Regional Seas and the Science of Astronomy and Navigation). There are two original magnetic declination determinations in Istanbul in 1727 and 1893 by Ottoman Turks. Also, many geomagnetic measurements between 1600 and 1917 were carried out during international campaigns in Ottoman geography.This study was carried out in History and Philosophy of Science, University of Cambridge and supported by Istanbul University Reseach Project Unite (project Numbver: IRP-49162).

Asian Americans (AA) are the fastest growing minority population in the United States. Leading AA scholars have highlighted the unmet service needs and the necessity to investigate subgroup variations in the mental health of AAs. This study addressed a research gap of whether racial and ethnic identity (REI) in three AA subgroups (Chinese, Filipino, and Vietnamese) consistently protects against major depressive disorder (MDD), counteracting the deleterious role of discrimination. Using the National Latino and Asian American Study (NLAAS), we explored the varying and incremental predictive values of REI, above and beyond the effects of known demographic and acculturation predictors, alongside other potentially protective factors. In three sets of two-step logistic regressions, REI had an inverse relationship with MDD in the Filipino subgroup only but a positive association in the Chinese subgroup. The damaging role of negative REI moderated the effect of discrimination. The longest stay in the United States and discrimination predicted a higher likelihood of a MDD diagnosis in the Filipino subgroup. Social support contributed to the lower odds of MDD in Chinese and Vietnamese subgroups, had lower odds of having MDD, and religious attendance may act as a protective factor in the Vietnamese subgroup. Our findings do not reinforce uniform protection of REI but lend partial support for two underlying rationales. Based on cultural psychologists' framework, inconsistent findings are interpreted within the sociocultural contexts of the 3 subgroups. © 2015 Wiley Periodicals, Inc.

Full Text Available This experiment was conducted in 1994 at Ames, Iowa, US to test whether cytoplasmic male-sterility can be used to decrease barrenness and to increase grain yield of maize at two plant populations. Four genotypes were tested: a hybrid (NK 6330 and an inbred, wifh sterile and fertile counterparts. Each genotype owas evaluated at plant populations equivalent to 25,000 and 75,000 pl. ha-1. Hybrids produced higher grain yield than inbreds at both plant populations. Gram yield was higher at 75,000 than at 25,000 pl. ha-1. No difference in gram yield, number of ears per plant, number of grains per ear, tassel length, and tassel number of branches was found between sterile and fertile counterparts of the inbred and hybrid, regardiess of plant population. Fertile genotypes bore heavier tassels at anthesis than their sterile counterparts. Adequate precipitation distribution and high fertility level in the soil probably decreased competition between tassel and ears, mitigating potential yield benefits of suppressing genetically pollen production.Este experimento foi conduzido em Ames, Iowa, US durante o ano agrícola de 1994, tendo como objetivo avaliar se a macho-esterelidade genético-citoplasmática pode ser utilizada para aumentar o rendimento de grãos de milho em diferentes populações de planta.

The redox cycling of manganese has pronounced effects on the adsorption of trace elements onto oxide surfaces is leaving these unavailable for the biota. Specific constants for the kinetics oxidation reaction of Mn in mangrove ecosystems have been measured. Water samples with different characteristics were collected in a tidal creek in a mangrove forest growth at Itacuruca, RJ. The methodology used to study the kinetics was, incubation of the water, in laboratory, with Mn-54. The oxides precipitates were filtered at constant intervals of time. The Mn-54 decay on the filters and filtrates were counted, for 600 s, in HPGe and associated electronics ORTEC. Ln A x t diagram showed an autocatalytic kinetic behavior. Temperature, pH, O{sub 2} dissolved, salinity, Mn (II) and Mn (IV) were appraised. The rate constant k{sup '}{sub 1}1 varied from 1,0 x 10{sup -5} to 4,0 x 10{sup -5} s{sup -1}. The k{sup '}{sub 2} rate constant had a larger variation, according to the other kinetic model that shows more of a heterogeneous affect, or catalysis via bacteria. We found a mean half life for Mn(II) of 12 h for the homogeneous kinetics in the mangrove. Rate constants increased with the pH, temperature, O{sub 2} dissolved, tide height, and decrease with salinity. (author)

Cyber stalking victimisation of women: Evaluating the effectiveness of current laws in India from restorative justice and therapeutic jurisprudential perspectives

Directory of Open Access Journals (Sweden)

Halder Debarati

2015-01-01

Full Text Available Victimisation of women through cyber stalking is one of the most serious crimes against women. Many countries including India have developed laws regulating cyber stalking. This article argues that since both, restorative justice (RJ and therapeutic jurisprudence (TJ are victim oriented, the issue of cyber stalking of women may be dealt with by RJ process and the laws in this regard must be analysed by the legal actors with a background in RJ and TJ philosophy. India had earlier taken up therapeutic punishment policy to enforce rights of the accused. But the modern principles of TJ have still not been considered in the RJ background in cyber stalking cases. This article therefore examines whether RJ and TJ principles can replace retributive principles for cyber stalking victimisation. It also examines the Indian cyber stalking law from RJ and TJ perspectives to assess its effectiveness for victims.

In 2011, the mountainous region of the State of Rio de Janeiro (Brazil) suffered enormous social and economic losses due to thousands of landslides caused by an extreme rainfall event. The mapping of the scars of these landslides in an area of 421 km2 in the municipality of Nova Friburgo, RJ - Brazil resulted in a total of 3622, and 89% of these scars were located in areas covered by grasses and forests. Despite the unexpected result (64% of scars in forest areas), field evidence has shown that most of the forest fragments in the municipality are in the initial stages of succession and in different states of degradation, evidencing the need for a better understanding of the role of these forests in the detonation and propagation of landslides. Two slope forest areas with different ages (20 and 50 years) were evaluated in relation to the vegetative aspects that influence the stability of the slopes in each area. Hydrological monitoring, including precipitation, interception by manual and automatic method, soil moisture and subsurface flows were performed in two different areas: forest and grass. Soil moisture was monitored by granular matrix sensors and flows by collecting troughs in trenches at depths of 0 cm, 20 cm, 50 cm, 100 cm, 150 cm and 220 cm, which were also analyzed for biomass and length of thick roots (> 2 mm diameter) and thin roots (particle size, aggregate stability, porosity and hydraulic conductivity in situ). In the grass area, the lower soil structure in relation to the forest areas makes it difficult to transmit the water through the soil matrix. During the monitoring period, that area preserved the moisture in depths of 100 cm, 150 cm and 220 cm. The fasciculate root system of the grasses increased the infiltration of water at the top of the soil, favouring the formation of more superficial saturation zones in the heavy rains, due to the hydraulic discontinuities. In forest areas, infiltration by preferential paths allows the concentration of

Dangerous liaisons?: A feminist and restorative approach to sexual assault

Directory of Open Access Journals (Sweden)

Pali Brunilda

2011-01-01

Full Text Available The appropriateness of restorative justice (RJ for gendered violence offences such as domestic violence and sexual assault has always been and still is highly contested. This paper focuses on the appropriateness of RJ measures in addressing sexual assault, primarily with reference to experience of restorative dialogues as practiced at the Centre for Victims of Sexual Assault in Copenhagen, and it takes a feminist approach to the application of RJ measures to sexual assault. Within this framework, the paper tackles two issues in particular: the privacy element of RJ versus the public aspect of the criminal justice system (CJS, and the intersection of the CJS and RJ in cases of sexual assault. In relation to the relationship between CJS and RJ, the authors argue that RJ could be used for victims of sexual assault, not primarily as part of diversion programmes, but when offered apart from and/or parallel to the CJS. In relation to the private/public debate, the authors argue that while RJ encounters, by taking place in highly confidential settings, might have a negative impact on efforts by women’s movements to move violence against women out of the private and into the public realm, creating high standard alternatives for individual women who are in need of support and constantly generating public debate about gendered violence is a good feminist response to this complex issue.

Applying the model in the proposed scenario (Angra 1 and 2 in operation and Angra 3 progressively reducing the capture and discharge after the accident), the simulated dilution of the specific activity of radionuclide spots, reached values much lower than report levels for seawater (1,1x10{sup 6} Bq/m{sup 3}, 1,11x10{sup 4} Bq/m{sup 3} and 1,85x10{sup 3} Bq/m{sup 3}) after 22 hours, respectively for {sup 3}H, {sup 60}Co, {sup 131}I and {sup 137}Cs. From the standpoint of public exposure to radionuclide dispersion, the results of activity concentration obtained by the model suggest that the observed radiological impact is negligible. Based on these findings, we conclude that there would be no radiological impact related to a further release of controlled effluent discharges into Itaorna cove. (author)

Upwelling systems contain a high diversity of pelagic microorganisms and their composition and activity are defined by factors like temperature and nutrient concentration. Denaturing gradient gel electrophoresis (DGGE) technique was used to verify the spatial and temporal genetic variability of Bacteria and Archaea in two stations of the Arraial do Cabo coastal region, one under upwelling pressure and another under anthropogenic pressure. In addition, biotic and abiotic variables were measured in surface and deep waters from three other stations between these stations. Six samplings were done during a year and adequately represented the degrees of upwelling and anthropogenic pressures to the system. Principal Component Analysis (PCA) showed negative correlations between the concentrations of ammonia and phosphorous with prokaryotic secondary production and the total heterotrophic bacteria. PCA also showed negative correlation between temperature and the abundance of prokaryotic cells. Bacterial and archaeal compositions were changeable as were the oceanographic conditions, and upwelling had a regional pressure while anthropogenic pressure was punctual. We suggest that the measurement of prokaryotic secondary production was associated with both Bacteria and Archaea activities, and that substrate availability and temperature determine nutrients cycling.

To examine the rational (systematic and rule-based) and experiential (fast and intuitive) decision-making preferences of student pharmacists, and to compare these preferences to the preferences of other health professionals and student populations. The Rational-Experiential Inventory (REI-40), a validated psychometric tool, was administered electronically to 114 third-year (P3) student pharmacists. Student demographics and preadmission data were collected. The REI-40 results were compared with student demographics and admissions data to identify possible correlations between these factors. Mean REI-40 rational scores were higher than experiential scores. Rational scores for younger students were significantly higher than students aged 30 years and older (prational decision making over experiential decision making, which was similar to results of studies done of other health professions.

Studies of diets have shown that marine foods are important sources of this radionuclide. The levels of {sup 210}Po have been determined in three highly consumed marine species, the fishes Sardinella brasiliensis (sardine) and Thunnus atlanticus (tuna), and the shrimp Litopenaeus brasiliensis, purchased from the Niteroi (RJ, Brazil) fish market, and caught along the coast of the state of Rio de Janeiro. Doses of {sup 210}Po were determined for the entire organisms and for some tissues and organs, such as eyes, heart, gills, muscle, stomach liver, intestine and pyloric caecal (fishes) or eyes, head content, exoskeleton, muscle, hepatopancreas and pleopods. {sup 210}Po is not uniformly distributed within these species, the highest levels being observed for sardine in the intestine (1634.6 mBq g-1), tuna in pyloric caecal (4656.1 mBq g-1) and shrimp in the hepatopancreas (1460.5 mBq g-1). The {sup 210}Po activities in sardine, tuna and shrimp, calculated on a mean whole-organism basis, were 64.6, 34.5 and 39.5 Bq kg-1 (dry weight) respectively, with corresponding concentration factors of 7.2 x104, 3.8 x104 and 4.4 x104. Considering body distribution, almost 60% of the total activity is concentrated in the pyloric caecal of both fishes and in the hepatopancreas of the shrimp. In turn, the edible parts concentrate much less activity. (author)

Full Text Available A região noroeste fluminense conta com um importante arranjo produtivo local no setor de beneficiamento de rochas ornamentais e de revestimento. Essa atividade é responsável por boa parte da renda local, empregando muitas pessoas. O principal produtor da região é o município de Santo Antônio de Pádua/RJ, que possui 154 empresas (78 pedreiras e 76 serrarias. A grande atividade de extração e beneficiamento das rochas vem causando na região problemas ambientais, pois durante as etapas de produção muito se perde devido a técnicas rudimentares e a deficiência no tratamento dos efluentes, o que acaba gerando impactos ao Rio Pomba, onde estes são lançados. O objetivo deste trabalho de pesquisa foi realizar um diagnóstico do uso da água no processo produtivo e a partir daí avaliar as diferentes alternativas para se ter um consumo otimizado e um tratamento dos efluentes a fim de minimizar os danos ambientais. Foram realizados alguns estudos de casos de caráter exploratório, pesquisas bibliográficas, entrevistas com proprietários, funcionários e profissionais ligadas ao setor de rochas e visitas técnicas a empresas da região. Os resultados apontam para uma falta de preparo e conhecimento técnico dos empresários e funcionários ao uso de novas tecnologias aliadas às questões ambientais no que se refere ao tratamento e consumo de água, principalmente para as pequenas empresas.

Full Text Available Cisplatin (CDDP is one of the most active cytotoxic agents in the treatment of cancer and has adverse side effects such as nephrotoxicity and hepatotoxicity. The present study was designed to determine the effects of royal jelly (RJ against oxidative stress caused by CDDP injury of the kidneys and liver, by measuring tissue biochemical and antioxidant parameters and investigating apoptosis immunohistochemically. Twenty-four Sprague Dawley rats were divided into four groups, group C: control group received 0.9% saline; group CDDP: injected i.p. with cisplatin (CDDP, 7 mg kg-1 body weight i.p., single dose; group RJ: treated for 15 consecutive days by gavage with RJ (300 mg/kg/day; group RJ + CDDP: treated by gavage with RJ 15 days following a single injection of CDDP. Malondialdehyde (MDA and glutathione (GSH levels, glutathione S-transferase (GST, glutathione peroxidase (GSH-Px, and superoxide dismutase (SOD activities were determined in liver and kidney homogenates, and the liver and kidney were also histologically examined. RJ elicited a significant protective effect towards liver and kidney by decreasing the level of lipid peroxidation (MDA, elevating the level of GSH, and increasing the activities of GST, GSH-Px, and SOD. In the immunohistochemical examinations were observed significantly enhanced apoptotic cell numbers and degenerative changes by cisplatin, but these histological changes were lower in the liver and kidney tissues of RJ + CDDP group. Besides, treatment with RJ lead to an increase in antiapoptotic activity hepatocytes and tubular epithelium. In conclusion, RJ may be used in combination with cisplatin in chemotherapy to improve cisplatin-induced oxidative stress parameters and apoptotic activity.

Existing variation in energy efficiency and its relationship with milk yield and milk composition, body weight and body condition, feed intake, and energy status was studied in primiparous Nordic Red dairy cattle with data including 3,752 weekly records from 145 cows. Energy efficiency was defined as energy conversion efficiency (ECE) and as residual energy intake (REI) estimated based on Finnish feeding standards (REI₁) or from the current data (REI₂). The results indicated true phenotypic variation in energy efficiency of the cows. The proportion of total variance due to the animal was 0.35 for REI₁, 0.30 for REI₂, and 0.50 for ECE. The high efficiency based on ECE was associated with increased mobilization of body reserves (r = -0.50) and decreased dry matter intake (r = -0.51). With REI as an energy efficiency measure, the increased efficiency was associated with a large decrease in feed intake (REI₁: r = 0.60; REI2: r = 0.74) without any effect on body weight change (REI₁: r = 0.13; REI2: r = 0.00). Increased efficiency based on ECE and REI₁ was associated with increased milk yield (ECE: r = 0.58; REI₁: r = -0.41). A clear effect of stage of lactation on REI was found, which could be caused by true differences in utilization of metabolizable energy during lactation. However, it might also be related, in part, to the lack of knowledge of the composition of body weight change in the beginning of lactation. Copyright © 2012 American Dairy Science Association.

Full Text Available Background: Royal jelly has been shown to have antioxidant and antidiabetic effects. The objective of this study was to evaluate the protective effect of RJ against kidney damage in streptozotocin induced diabetic rats. Methods: Thirty two male Wistar rats were divided randomly into four groups (n=8 per group. Normal control and diabetic control groups received 1cc/day distilled water, normal RJ-treated and diabetic RJ-treated groups received 100mg RJ/kg body weight daily. Diabetes was induced by intraperitoneal injection of streptozotocin. At the end of the experiment, urine and kidney samples were collected for biochemical and histopathological analysis. Results: The results showed that diabetes could increase levels of urine urea, total protein and albumin significantly, and could decrease the levels of creatinine and uric acid in urine. In the kidney tissue homogenates, catalase activity and antioxidant power were significantly lower, whereas malondialdehyde levels were significantly higher in diabetic group when compared with control group. Diabetic rats showed severe histological changes in kidney tissues. Treatment of diabetic rats with RJ improved significantly all of these parameters. Conclusion: The present study revealed that treatment with RJ resulted in significant improvement in histopathological alterations in kidney tissue and urine parameters of diabetic rats. This could be due to its antioxidant activity and the ability of RJ for scavenging the free radicals released in diabetes. These findings suggest that RJ has protective effects on kidneys affected by diabetes mellitus.

The content of 10-hydroxy-trans-2-decenoic acid (10-HDA), a marker compound in royal jelly (RJ), is the most important criterion in grading RJ for commercial trade and varies with its origin. To identify the effect of geographical origin on 10-HDA content in RJ, 138 samples were collected from 19 provinces of China (divided into three groups) produced by either Apis mellifera ligustica Spinola, 1806 or a hybrid of A. m. ligustica and Apis mellifera carnica Pollman, 1879 and analyzed for moisture, sugar, crude protein, ash, acid, and 10-HDA concentration. The results show that RJ from western China has a significantly higher 10-HDA level (2.01 +/- 0.05%) than those from northeastern (1.87 +/- 0.05%) and eastern (1.75 +/- 0.03%) China. RJ secreted by hybrid bees contained more 10-HDA (1.89 +/- 0.03%) than that secreted by A. m. ligustica (1.78 +/- 0.03%). The 10-HDA content of RJ produced during flowering of rape (Brassica campestris L.), lime (Tilia amurensis Ruprecht), and vitex (Vitex negundo L. variety heterophylla (Franch.) Rehder) was 1.92, 1.80, and 1.68%, respectively. The results would be helpful during the process of price determination of RJ by providing some basis of geographical, bee strain, and botanical information for commercial trade.

Due to the populations' susceptibility, DENV-4 introduction in 2010 led to the occurrence of explosive epidemics in the following years in Brazil. In 2011, DENV-4 was identified in Rio de Janeiro (RJ) and it was prevalent in 2012 and 2013. Here, we aimed to characterize clinical, epidemiological and laboratorial aspects of DENV-4 cases after this serotype introduction in an endemic scenario. Dengue suspected cases (n = 3727) were received and analyzed from January 2011 to December 2013, during outbreaks occurred in RJ, Brazil. Samples were submitted to virological, serological and molecular methods for case confirmation. DENV-4 cases (n = 705) were characterized according to the type of infection, disease severity and, viremia levels and NS1 antigenemia were accessed. Representative strains were partial sequenced for genotyping. DENV-4 was identified in 44.2% (705/1593) of dengue positive cases, virus isolated in 48.7% of the cases. Anti-DENV IgM was detected in 39.4% of the cases, however an increased detection was observed in cases with ≥4 days of symptoms (57.0%). NS1 antigen was identified in 41.5% of DENV-4 cases however, after immune complexes dissociation, the detection significantly increased (87.6%). Females were more affected than males, so did children aged 11-15 years old. Primary cases were more frequently observed than secondary ones and most of them were classified as dengue. No differences on NS1 antigenemia and viraemia within the groups were observed. Despite the higher frequency of severe disease on individuals >65 years old, no differences were observed among the groups and type of infection. However, DENV-4 fatal cases were more frequent on secondary infections (57.1%). DENV-4 Genotype II was identified with a probable origin from Venezuela and Colombia. It has been shown that laboratorial diagnosis is still a reliable tool for the disease surveillance, detecting and confirming emerging epidemics. Despite the occurrence of secondary

Royal jelly (RJ), secreted by honeybee workers, plays diverse roles as nutrients and defense agents for honeybee biology and human health. Despite being reported to be glycoproteins, the glycosylation characterization and functionality of RJ proteins in different honeybee species are largely unknown. An in-depth N-glycoproteome analysis and functional assay of RJ produced by Apis mellifera lingustica (Aml) and Apis cerana cerana (Acc) were conducted. RJ produced by Aml yielded 80 nonredundant N-glycoproteins carrying 190 glycosites, of which 23 novel proteins harboring 35 glycosites were identified. For Acc, all 43 proteins glycosylated at 138 glycosites were reported for the first time. Proteins with distinct N-glycoproteomic characteristics in terms of glycoprotein species, number of N-glycosylated sites, glycosylation motif, abundance level of glycoproteins, and N-glycosites were observed in this two RJ samples. The fact that the low inhibitory efficiency of N-glycosylated major royal jelly protein 2 (MRJP2) against Paenibacillus larvae (P. larvae) and the absence of antibacterial related glycosylated apidaecin, hymenoptaecin, and peritrophic matrix in the Aml RJ compared to Acc reveal the mechanism for why the Aml larvae are susceptible to P. larvae, the causative agent of a fatal brood disease (American foulbrood, AFB). The observed antihypertension activity of N-glycosylated MRJP1 in two RJ samples and a stronger activity found in Acc than in Aml reveal that specific RJ protein and modification are potentially useful for the treatment of hypertensive disease for humans. Our data gain novel understanding that the western and eastern bees have evolved species-specific strategies of glycosylation to fine-tune protein activity for optimizing molecular function as nutrients and immune agents for the good of honeybee and influence on the health promoting activity for human as well. This serves as a valuable resource for the targeted probing of the biological

Royal Jelly Reduces Cholesterol Levels, Ameliorates Aβ Pathology and Enhances Neuronal Metabolic Activities in a Rabbit Model of Alzheimer’s Disease

Full Text Available Alzheimer’s disease (AD is the most common form of dementia characterized by aggregation of amyloid β (Aβ and neuronal loss. One of the risk factors for AD is high cholesterol levels, which are known to promote Aβ deposition. Previous studies have shown that royal jelly (RJ, a product of worker bees, has potential neuroprotective effects and can attenuate Aβ toxicity. However, little is known about how RJ regulates Aβ formation and its effects on cholesterol levels and neuronal metabolic activities. Here, we investigated whether RJ can reduce cholesterol levels, regulate Aβ levels and enhance neuronal metabolic activities in an AD rabbit model induced by 2% cholesterol diet plus copper drinking water. Our results suggest that RJ significantly reduced the levels of plasma total cholesterol (TC and low density lipoprotein-cholesterol (LDL-C, and decreased the level of Aβ in rabbit brains. RJ was also shown to markedly ameliorate amyloid deposition in AD rabbits from Aβ immunohistochemistry and thioflavin-T staining. Furthermore, our study suggests that RJ can reduce the expression levels of β-site APP cleaving enzyme-1 (BACE1 and receptor for advanced glycation end products (RAGE, and increase the expression levels of low density lipoprotein receptor-related protein 1 (LRP-1 and insulin degrading enzyme (IDE. In addition, we found that RJ remarkably increased the number of neurons, enhanced antioxidant capacities, inhibited activated-capase-3 protein expression, and enhanced neuronal metabolic activities by increasing N-acetyl aspartate (NAA and glutamate and by reducing choline and myo-inositol in AD rabbits. Taken together, our data demonstrated that RJ could reduce cholesterol levels, regulate Aβ levels and enhance neuronal metabolic activities in AD rabbits, providing preclinical evidence that RJ treatment has the potential to protect neurons and prevent AD.

Bucks in the 1st, 2nd, 3rd, and 4th group were supplemented with 0, 50, 100 or 150 mg of Chinese royal jelly (RJ/kg twice per week, respectively, over a 20-wk period. Semen quality and blood biochemical constituents were evaluated. RJ at any dose exhibited a significant increase (P<0.05 in rabbits’ sperm concentration, total sperm output, sperm motility, live sperm and normal sperm compared to the untreated controls. Plasma total protein, albumin, globulin, glucose and high density lipids (HDL concentrations were significantly (P<0.05 boosted in the RJ groups compared to the controls. In contrast, RJ treatment resulted in a significant (P<0.05 reduction in plasma total lipids, triglycerides, cholesterol and low density lipids (LDL concentrations. Treatment with RJ significantly boosted (P<0.05 testosterone concentration in the RJ groups to reach 110, 120 and 128%, respectively, of the control group. Improved kidney and liver functions were observed in the RJ bucks groups where plasma creatinine, urea concentrations, aspartate aminotransferase and alanine aminotransferase enzyme activities were significantly (P<0.05 decreased by RJ treatments. Treating bucks subjected to heat stress by different RJ doses increased (P<0.05 total antioxidant capacity to 106, 111 and 115% of basal, but significantly reduced (P<0.05 malondialdehyde and thiobarbituric acid reactive substances compared to the untreated. It was concluded that Chinese royal jelly supplementation for heat-stressed male rabbits can counteract summer infertility and improve their physiological status.

Full Text Available Background: An adverse effect of oxymetholone (OXM, an anabolic-androgenic steroid used as energetic medicine, is reproductive toxicity. Royal jelly (RJ is an efficient antioxidant that has been used to treat reproductive problems. In this study, we investigated the effects of RJ on OXM-induced oxidative injuries in mouse testes. Methods: Male mice were divided into four groups. Two groups of mice were administered OXM (5 mg/kg/day, p.o. for 28 days. One of these groups received RJ (100 mg/kg/day, p.o. concurrently. A vehicle-treated control group and a RJ control group were also included. Results: The OXM-treated group showed a significant decrease in the serum testosterone concentration and spermatogenic activities, along with many histological alterations. OXM treatment also caused a significant decrease in catalase activity with an increase in lipid peroxidation in the mouse testes. The above-noted parameters were restored to near normal levels by RJ co-administration. Conclusion: The results demonstrate that RJ protects against OXM-induced reproductive toxicities.

Full Text Available The Western honey bee (Apis mellifera is a social insect characterized by caste differentiation in which the queen bee and worker bees display marked differences in morphology, behavior, reproduction, and longevity despite their identical genomes. The main causative factor in caste differentiation is the food fed to queen larvae, termed royal jelly (RJ. Alternative splicing (AS is an important RNA-mediated post-transcriptional process in eukaryotes. Here we report AS changes in A. mellifera after being fed either A. mellifera RJ or A. cerana RJ. The results demonstrated that the RJ type affected 4 types of AS in adult A. mellifera: exon skipping, intron retention, alternative 5’ splice sites, and alternative 3’splice sites. After feeding with A. cerana RJ, AS occurred in many genes in adult A. mellifera that encode proteins involved in development, growth, the tricarboxylic acid cycle, and substance metabolism. This study provides the first evidence that heterospecific RJ can influence the AS of many genes related to honey bee development and growth.

Considerando o ambiente similar em termos da vegetação original e o uso agrícola, as mudanças no carbono do solo e nas frações húmicas podem refletir as interações com os componentes minerais e processos pedogenéticos, influenciados pelo material de origem e o relevo.

Full Text Available Este trabalho objetiva investigar a dinâmica geomorfológica glacial das áreas livres de gelo na Península Potter, Ilha Rei George, Antártica, em resposta à recente retração da geleira Polar Club. O mapeamento geomorfológico e a interpretação da evolução dos sistemas lacustres entre 2006 e 2011 das áreas livres de gelo na Península Potter foi realizado através da interpretação visual em uma imagem Quickbird (RGB432, em imagens COSMO-SkyMed polarizações VV e HH em modo spotlight processadas com filtros espaciais e perfis topográficos. Também foram considerados os aspectos morfométricos da península, interpretados através da geração de mapas de hipsometria, declividade, curvas de nível e sombreamento. A variação frontal da geleira Polar Club entre os anos de 1981 a 2015 foi obtida pela análise temporal de imagens Landsat. O mapeamento geomorfológico da Península Potter evidenciou os processos geomorfológicos proglaciais e o padrão de disposição espacial das feições lineares marginais ao gelo, como cordões morâinicos e feições glaciofluviais (relacionadas ao aporte da fusão sazonal da neve e do gelo, bem como terraços marinhos, ravinas e afloramentos rochosos. O modelo de evolução da variação frontal da geleira Polar Club indica que condição de último avanço glacial registrado pela geomorfologia proglacial pode estar relacionado à Pequena Idade do Gelo e que houve um contínuo processo de retração desde então. Entre 1981-2015 evidenciou-se a redução de área de 2,95km² para a geleira Polar Club (perda de área total de 9,4%. Este processo pode estar relacionado com a tendência de aumento das temperaturas médias do ar, a tendência de aumento de dias com precipitação líquida no verão e o número de dias em que a temperatura média ultrapassou os 0°C na região nas últimas décadas. O recuo da geleira Polar Club é pouco expressivo quando comparado a outras geleiras da Ilha Rei George

The Phenotypic Effects of Royal Jelly on Wild-Type D. melanogaster Are Strain-Specific.

Directory of Open Access Journals (Sweden)

Full Text Available The role for royal jelly (RJ in promoting caste differentiation of honeybee larvae into queens rather than workers is well characterized. A recent study demonstrated that this poorly understood complex nutrition drives strikingly similar phenotypic effects in Drosophila melanogaster, such as increased body size and reduced developmental time, making possible the use of D. melanogaster as a model system for the genetic analysis of the cellular mechanisms underlying RJ and caste differentiation. We demonstrate here that RJ increases the body size of some wild-type strains of D. melanogaster but not others, and report significant delays in developmental time in all flies reared on RJ. These findings suggest that cryptic genetic variation may be a factor in the D. melanogaster response to RJ, and should be considered when attempting to elucidate response mechanisms to environmental changes in non-honeybee species.

Full Text Available O trabalho discute temas relacionados à distribuição de sedimentos costeiros, parâmetros granulométricos e modelos bidimensionais de transporte de sedimentos. Parte-se da hipótese de que a disposição dos materiais na superfície de fundo das enseadas permite o diagnóstico de processos associados à hidrodinâmica marinha e sua participação no controle do transporte e distribuição dos sedimentos costeiros. O objetivo central é então caracterizar a textura superficial do depósito costeiro e apresentar correlações entre os parâmetros estatísticos que permitam o diagnóstico de processos relacionados à distribuição e ao transporte dos sedimentos no sistema praia-antepraia. Como área de pesquisa, foram selecionadas três enseadas no município de Arraial do Cabo (RJ. As etapas metodológicas partiram da definição de uma malha amostral, coleta de 96 amostras de sedimentos em profundidades entre 1 e 23 metros, seguido por análises granulométricas em laboratório, determinação de parâmetros estatísticos e cálculo do modelo de tendências de transporte de sedimentos (GSTA. Os resultados apontam a ocorrência majoritária de areias finas (41,6% e médias (17,7% moderadamente bem selecionadas como o principal depósito nas enseadas, no entanto, além dos depósitos palimpsestos, núcleos de deposição de areias grossas (14,6% e muito grossas (8,3% e, por outro lado, areias muito finas (5,2% e siltes (6,2% também foram identificados e discutidos à luz de sua significância ambiental. Quanto ao modelo de transporte, o melhor ajuste (65% foi feito com o padrão FB, que indica sedimentos mais finos e mais bem selecionados na direção do transporte. Conclui-se que os depósitos palimpsestos são responsáveis pelo abastecimento da praia emersa e que os esforços de interpretação dos parâmetros estatísticos e a geração de resultados de transporte de sedimentos a partir de modelos não hidrodinâmicos geram informa

Abstract. This study evaluated the pupa-productivity of the entomologic surveillance according methodology used by the official Program for Dengue Control in Brazil (PDCB for Aedes aegypti (Linnaeus and Aedes albopictus (Skuse in Parati, RJ, Brazil. The highest number of A. aegypti pupae were found in drains (31%, bottles and cans (23%; and the highest number of A. albopictus pupae were found in bottles and cans (24%, and plant vases (21%. Of the total pupae identified 84.3% and 79.3% of A. aegypti and A. albopictus respectively were collected in small receptacles: bottles, plants vase, tires, bromeliads and tree holes. These productivities are not supported by literature and can be explained by the restrictions of access for the bigger receptacles and lack of training of the agents. The study points out the importance which the small receptacles can have on vector densities in urban environment despite of their productivity and conclude that the entomology surveillance methodology for dengue used in PDCB has no efficacy to identify the bigger and more productive receptacles. This conclusion suggests that this inefficacy can be an important factor for the failures on dengue vector control in Brazil.

Full Text Available Introduction: Studies have proposed that royal jelly(RJ has various biological activities in different cells and tissues. Since it has been demonstrated that RJ contains compounds having desirable effects on central neurons system and neural functions, the present study aimed to investigate the effect of royal jelly on learning and memory in rats. Methods: Male wistar rats were divided into two groups, the royal jelly and the control. In the RJ group, the rats received a food that contained 3% RJ instead of regular food for 10 days. Then learning and memory were investigated in these animals through both passive avoidance learning test(1 day and 1 week after receiving electrical shock and Morris water maze test(1 day and 1 week after a 4-day learning period. Results: The study results indicated that the food containing RJ in the RJ group significantly increased the time of the first entrance to the dark room one week after the electrical shock in passive avoidance learning test. In other words, the findings suggest an improvement of learning and memory in RJ group. In the acquisition phase of Morris water maze test, rats receiving RJ found the underwater escape plate during less time and distance comparing with the control group. Furthermore, one week after the acquisition phase, in the retention phase, rats spent more time in the quadrant in which the escape plate was previously located. Conclusion: The present study findings propose that Royal Jelly can improve cognitive processes through positive effects on neural functions and probably has a significant influence on prevention and therapy of some neuronal disorders.

Juno's 53-day polar orbits cut through the equatorial plane when inbound to perijove. The JADE instrument has been observing thermal ions (0.01-50 keV/q) and electrons (0.1-100 keV/q) in these regions since Orbit 05. Even at distances greater than 70 RJ, magnetodisk crossings are clear with high count rates measured before returning to rarified plasma conditions outside the disk. However JADE's detectors observes regions of slightly greater ion counts that last for about an hour. The ion counts are too low to analyze at the typical 30s or 60s low rate instrument cadence, but by summing to 10-minute resolution the features become analyzable. We find these regions are populated with protons with higher density than those typically observed outside the magnetodisk, and that they are colder than the ambient plasma. Reanalysis of Voyager data (DOI: 10.1002/2017JA024053) also showed cold dense blobs of plasma in the inner to middle magnetosphere, however these were of heavier ion species, short lived (several minutes) and within 40 RJ of Jupiter. This presentation will investigate the JADE identified cold blobs observed to date and compare with those observed with Voyager.

A new CZE method was developed and compared with HPLC for the determination of (E)-10-hydroxy-2-decenoic acid (10-HDA) in royal jelly (RJ) samples of different geographical origin. The results obtained with the CZE method were highly correlated with those of HPLC (p HDA/mL), a good sensitivity (LOD and LOQ were 0.002 and 0.004 mg/mL, respectively) and a satisfactory instrumental repeatability with respect to migration time and peak area (RSD% less than 1.0 and 2.0% on migration time for intra- and interday assay, respectively and less than 2.0 and for 4.0% on peak area for intra- and interday assay, respectively). The 10-HDA content in RJ ranged from 0.8 to 3.2 g/100 g of RJ and a significant difference (p < 0.05) was found between the Italian and extra-European average values: 2.5 and 1.6 g/100 g of RJ, respectively, according to the CZE data. The possibility of application of CZE for routine analyses on RJ and RJ based products to verify their authenticity is highlighted here.

Symbiosis between legumes and rhizobia leads to the formation of N2-fixing root nodules. In soybean, several host genes, referred to as Rj genes, control nodulation. Soybean cultivars carrying the Rj4 gene restrict nodulation by specific rhizobia such as Bradyrhizobium elkanii We previously reported that the restriction of nodulation was caused by B. elkanii possessing a functional type III secretion system (T3SS), which is known for its delivery of virulence factors by pathogenic bacteria. In the present study, we investigated the molecular basis for the T3SS-dependent nodulation restriction in Rj4 soybean. Inoculation tests revealed that soybean cultivar BARC-2 (Rj4/Rj4) restricted nodulation by B. elkanii USDA61, whereas its nearly isogenic line BARC-3 (rj4/rj4) formed nitrogen-fixing nodules with the same strain. Root-hair curling and infection threads were not observed in the roots of BARC-2 inoculated with USDA61, indicating that Rj4 blocked B. elkanii infection in the early stages. Accumulation of H2O2 and salicylic acid (SA) was observed in the roots of BARC-2 inoculated with USDA61. Transcriptome analyses revealed that inoculation of USDA61, but not its T3SS mutant in BARC-2, induced defense-related genes, including those coding for hypersensitive-induced responsive protein, which act in effector-triggered immunity (ETI) in Arabidopsis. These findings suggest that B. elkanii T3SS triggers the SA-mediated ETI-type response in Rj4 soybean, which consequently blocks symbiotic interactions. This study revealed a common molecular mechanism underlying both plant-pathogen and plant-symbiont interactions, and suggests that establishment of a root nodule symbiosis requires the evasion or suppression of plant immune responses triggered by rhizobial effectors. © The Author 2016.

Full Text Available Este trabalho avalia a viabilidade técnica e econômica de se implantar um sistema de coleta de águas pluviais em uma instituição de ensino e uma residência, ambas localizadas no município de Campos dos Goytacazes, RJ. A pluviometria da cidade, área de captação e a estimativa do consumo de água não potável foi estimada para a Universidade Candido Mendes e uma residência dimensionada para cinco moradores. O custo de implantação, manutenção e valor da água tratada foi usado para calcular a viabilidade econômica do sistema. A precipitação na década de 2000 é significativamente maior do que na década de 1990. Os quatro primeiros e os dois últimos meses do ano são os mais chuvosos, enquanto que junho a agosto são mais secos. Apesar da água coletada atender a 100% da demanda, o projeto não é economicamente viável na residência. Na universidade, a coleta atenderia a 27% da demanda anual, no entanto, seria economicamente viável. O armazenamento e uso de água pluvial em áreas urbanas colaboram para a preservação do meio ambiente, é uma ferramenta de educação ambiental, evita enchentes, escassez e traz benefícios econômicos devido a redução do consumo de água tratada. Sua implantação em residência poderia ser incentivada com atos governamentais, como a redução de impostos. Para as empresas, além de redução de custos, é um sistema que pode compor o marketing verde, um seguimento de mercado em ascensão.

Full Text Available Estudos fenológicos podem servir de subsídio para ações de colheita de sementes e recuperação de áreas degradadas, contribuindo para a conservação das espécies florestais. Este trabalho teve como objetivo conhecer a época de floração e frutificação de 21 espécies arbóreas nativas em área fragmentada de Mata Atlântica em Itaboraí, RJ. Foram acompanhadas mensalmente 91 matrizes, no período de janeiro a dezembro de 2011. A maior parte das espécies floresceu no final da estação seca e início da chuvosa, tendo sido observada correlação moderada e negativa entre floração e fotoperíodo. Observaram-se dois picos de frutificação: de março a abril para as espécies zoocóricas, e de setembro a outubro para espécies não zoocóricas, com correlação positiva entre precipitação e frutificação de espécies zoocóricas. Foi alta a incidência de patógenos nos frutos, comprometendo a produção de sementes de Machaerium hirtum, Melanoxylon brauna, Machaerium brasiliense e Psidium guineense. Outras espécies apresentaram baixa produção de frutos, como Andira sp., Swartzia oblata, Guarea guidonea e Enterolobium glaziovii. A sincronia de floração e frutificação entre as matrizes foi baixa para a maioria das espécies. A falta de trabalhos de fenologia para a maioria das espécies estudadas (52% reforça a necessidade de pesquisa para a região de estudo.

2008-10-01

In Study 1 (N= 203) the factor structure of a Swedish translation of Pacini and Epstein's Rational-Experiential Inventory (REI-40) was investigated using confirmatory factor analysis. The hypothesized model with rationality and experientiality as orthogonal factors had satisfactory fit to the data, significantly better than alternative models (with two correlated factors or a single factor). Inclusion of "ability" and "favorability" subscales for rationality and experientiality increased fit further. It was concluded that the structural validity of the REI is adequate. In Study 2 (N= 72) the REI-factors were shown to have theoretically meaningful correlations to other personality traits, indicating convergent and discriminant validity. Finally, scores on the rationality scale were negatively related to risky choice framing effects in Kahneman and Tversky's Asian disease task, indicating concurrent validity. On the basis of these findings it was concluded that the test has satisfactory psychometric properties.

Mega-thrust earthquakes are anticipated to occur in the Nankai Trough in southwest Japan. In the source areas, we have deployed seafloor seismic network, DONET (Dense Ocean-floor Network System for Earthquake and Tsunamis), in 2010 in order to monitor seismicity, crustal deformations, and tsunamis. DONET system consists of totally 20 stations, which is composed of six kinds of sensors, including strong-motion seismometers　and quartz pressure gauges. Those stations are densely distributed with an average spatial interval of 15-20 km and cover near the trench axis to coastal areas. Observed data are transferred to a land station through a fiber-optical cable and then to JAMSTEC (Japan Agency for Marine-Earth Science and Technology) data management center through a private network in real time. After 2011 off the Pacific coast of Tohoku Earthquake, each local government close to Nankai Trough try to plan disaster prevention scheme. JAMSTEC will disseminate DONET data combined with research accomplishment so that they will be widely recognized as important earthquake information. In order to open DONET data observed for research to local government, we have developed a web application system, REIS　(Real-time Earthquake Information System). REIS is providing seismic waveform data to some local governments close to Nankai Trough as a pilot study. As soon as operation of DONET is ready, REIS will start full-scale operation. REIS can display seismic waveform data of DONET in real-time, users can select strong motion and pressure data, and configure the options of trace view arrangement, time scale, and amplitude. In addition to real-time monitoring, REIS can display past seismic waveform data and show earthquake epicenters on the map. In this presentation, we briefly introduce DONET system and then show our web　application system. We also discuss our future plans for further developments of REIS.

This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models of hydrodynamics and transport for the simulation of tritium dispersion caused by an accident in a CANDU reactor located in the ongoing Angra 3 site. It was postulated, then, the LOCA - Loss of Coolant Accident -, accident in the emergency cooling system of the nucleus ( without fusion), where was lost 66m 3 of soda almost instantaneously. This inventory contained 35 PBq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios ( plant stopped or operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1MBq/m 3 ), during the first 14 days after the accident. The main difference between the scenario without and with seawater recirculation (pumping and discharge) is based on the enhancement of dilution of the highest concentrations in the last one. This dilution enhancement resulting in decreasing concentrations was observed only during the first two weeks, when they ranged from 1x10 9 to 5x10 5 Bq/m 3 close to the Itaorna beach spreading just to Sandri Island. After 180 days, the plume could not be detected anymore in the bay, because their activities would be lower than the minimum detectable value ( 3 ). (author)

Full Text Available Background: Diabetes is the most common endocrine disease. It has adverse effects on male reproductive function. Royal Jelly (RJ has antioxidant and anti-diabetic effects and show protective effects against diabetes. Objective: This study was conducted to evaluate the effect of RJ on histopathological alterations of the testicular tissue in streptozotocin (STZ-induced diabetic rats. Materials and Methods: In this experimental study, 28 adult Wistar rats were randomly divided into control (C, royal jelly (R, diabetic (D and RJ-treated diabetic (D+R groups. Diabetes was induced by a single intraperitoneal injection of STZ at 50 mg/kg body weight (BW. The rats from the R and D+R groups received daily RJ (100 mg/kg BW for 6 wks orally. Hematoxylin-Eosin staining was used to analyze histopathological changes including: tunica albuginea thickness (TAT, seminiferous tubules diameter (STsD, Johnsen’s score, tubular differentiation index (TDI, spermiogenesis index (SPI, Sertoli cell index (SCI, meiotic index (MI, and mononuclear immune cells (MICs in testes. The antioxidant status was examined by evaluating testicular levels of ferric reducing antioxidant power (FRAP and catalase (CAT activity. Results: Histological results of the testis from diabetic rats showed significant decrease in STsD, Johnsen’s score, TDI, SPI, SCI and MI, and significant increase in TAT and MICs, while administration of RJ significantly reverted these changes (p<0.05. RJ treatment markedly increased activity of CAT and FRAP. There were significant differences in FRAP levels among C (13.0±0.5, RJ (13.4±0.3, D (7.8±0.6 and D+R (12.4±0.7 groups (p<0.05. Conclusion: RJ improved diabetes-induced impairment in testis, probably through its antioxidant property.

Full Text Available Introduction & Objective: Wound healing is the process of repairing following injury to the skin and other soft tissues. Following injury, inflammatory response occurs and the cells below the dermis begin to increase collagen production, later on, the epithelial tissue is regenerated. Royal jelly (RJ is a bee product. There are many reports on pharmacological activity of RJ on experimented animals. The purpose of this study was to investigate the effect of RJ on the induction of wound healing of sterile incision in Balb/C mice. Materials & Methods: In this experimental study which was conducted at Shahr-e-kord University of Medical Sciences in 60 female Balb/C mice (8 weeks old were selected. The mice were anesthetized with ether. The dorsal fur of the animals was shaved and sterilized with alcohol, and then a longitudinal para vertebral full thickness incision of 10mm long was made. The animals were then divided into six equal groups. In group one (negative control, nothing was applied to the wound. Group 2 (positive control was treated with nitrofurazon ointment, group 3 was treated with RJ 200 mg/kg daily, group 4 was treated with RJ 200 mg/kg every two days, group 5 was treated with RJ 300 mg/kg daily, group 6 treated with RJ 300 mg/kg every two days. Royal jelly was topically used on the wounds. The wound length was measured with vernier capilar every two days until the complete healing was occurred. The data were analyzed with SPSS version 11.5 using Kruscal Walis tests. Results: There was a significant difference between groups 1, 2 with the other groups (p0.015. Conclusion: The results of this study indicated that daily application of RJ possesses betters wound healing effects than nitrofurazon.

Stapf, Suázi (Digitaria swazilandensis Stent and Tifton 85 (Cynodon spp. cv Tifton 85 cultivated in hill relief. Soil samples were collected at 0-10 and 10 -30 cm depth in two times; dry period (August of 2004, May of 2005 and August of 2005 and in the rainy period (December of 2004 in different sections: at the hillside shoulder (TS, backslope (TM and footslope (TI positions. In the samples soil chemical and physical analyses were accomplished. Were evaluated the soil aggregate stability; the bulk density (BD and the total volume of pores (TVP, total organic carbon (TOC and soil fertility. To study the multidimensional effect of soil attributes the Principal Component Analysis (PCA was applied. The pastures areas showed a good aggregation levels, in the different times and depths evaluated. The grasses Tifton 85 and Braquiária propitiated a higher TOC contribution in the depth of 0-10 cm and also larger aggregate weight in the class> 2,0mm, in the dry period. Higher values of BD were observed in the TI. In the rainy period it was observed a BD reduction and TVP increase, mainly for the Suázi areas. In a general way, the positions of the hillside TS and TM were the ones that showed the higher values for the physical and chemical attributes indicating a better soil quality in these areas. In the TI area the lowest levels of soil quality were observed, possibly for the accentuated steepness of this last position of the slope in relation to the other positions. The PCA separated the areas in function of seasonal variation. The dry season presented the higher correlation values with soil quality attributes such as the aggregation indexes and TOC. The aggregate weight distribution in function of the size classes, especially > 2,0 mm, MGD, MWD and TOC were a indicative

Full Text Available Purpose. One of the common side effects experienced by head and neck cancer patients on chemoradiotherapy is mucositis. Severe mucositis may be controllable by limiting cancer therapy, but it has resulted in decreasing the completion rate of chemoradiotherapy. The efficacy of royal jelly (RJ as prophylaxis against chemoradiotherapy-induced mucositis was evaluated through clinical scoring of oral and pharyngeal mucositis. Methods. In this randomized, single-blind (physician-blind, clinical trial, 13 patients with head and neck cancer requiring chemoradiation were randomly assigned to two groups. Seven patients assigned to the study group received RJ, and 6 patients were assigned to the control group. RJ group patients took RJ three times per day during treatment. The patients in both groups were evaluated twice a week for the development of mucositis using Common Terminology Criteria for Adverse Events version 3.0. Results. A significant reduction in mucositis was seen among RJ-treated patients compared with controls (P<0.001. Conclusion. This study demonstrated that prophylactic use of RJ was effective in reducing mucositis induced by chemoradiotherapy in head and neck cancer patients. However, further studies are needed because of the small sample size and the absence of double blinding.

Dry eye is a multifactorial disease characterized by ocular discomfort and visual impairment. Lacrimal gland function has been shown to decrease with aging, a known potent risk factor for dry eye. We have previously found that orally administrated royal jelly (RJ) restored tear secretion in a rat model of dry eye. We examined the effects of RJ oral administration on dry eye in this prospective, randomized, double-blind, placebo-controlled study. Forty-three Japanese patients aged 20-60 years with subjective dry eye symptoms were randomized to an RJ group (1200 mg/tablet, six tablets daily) or a placebo group for 8 weeks. Keratoconjunctival epithelial damage, tear film break-up time, tear secretion volume, meibum grade, biochemical data, and subjective dry eye symptoms based on a questionnaire were investigated at baseline, and at 4 and 8 weeks after intervention. Adverse events were reported via medical interviews. In the RJ group, tear volume significantly increased after intervention (p = 0.0009). In particular, patients with a baseline Schirmer value of ≤10 mm showed a significant increase compared with baseline volume (p = 0.0005) and volume in the placebo group (p = 0.0051). No adverse events were reported. We also investigated the effect of RJ (300 mg/kg per day) administration using a mouse model of dry eye. Orally repeated administration of RJ preserved tear secretion, potentially through direct activation of the secretory function of the lacrimal glands. Our results suggest that RJ improves tear volume in patients with dry eye. Registered NO. the University Hospital Medical Information Network in Japan (UMIN000014446).

Full Text Available OBJETIVO: Analisar diferenças socioculturais e percepções sobre a consulta ginecológica por adolescentes. MÉTODOS: Estudo transversal com 418 alunas do ensino médio de três escolas de diferentes perfis, localizadas na cidade do Rio de Janeiro, RJ, em 2010. Aplicou-se questionário estruturado, abordando características sociodemográficas, comportamento sexual e avaliação da consulta ginecológica. Utilizou-se o teste de Qui-quadrado (Yates e o t de Student, adotando-se p < 0,05. RESULTADOS: Alunas dos colégios privado e público apresentaram perfis semelhantes e diferiram daquelas da rede pública estadual que tiveram nível socioeconômico mais baixo, menor escolaridade dos responsáveis, predominância da raça negra, maior número de parceiros, gestações e histórico de violência sexual. As médias de idades da menarca e sexarca foram semelhantes entre as estudantes e a primeira consulta ginecológica foi significativamente mais tardia nas alunas da rede estadual. A maioria referiu conhecimento sobre anticoncepção e doenças sexualmente transmissíveis, porém pequena parte obteve essas orientações na consulta. As estudantes manifestaram desejo de que o profissional investisse mais tempo, paciência e disponibilidade no atendimento. CONCLUSÕES: O atendimento ginecológico na adolescência é insatisfatório segundo a avaliação das adolescentes estudadas. As usuárias dos serviços privados submetem-se à consulta ginecológica em idade mais precoce do que aquelas que têm acesso apenas à rede pública. É necessário criar mecanismos que facilitem o acesso e a adesão desse grupo etário à rotina preventiva ginecológica.

A partir de um questionário contendo sete perguntas, foram analisados 2585 discentes vinculados a 1ª e 3ª série de doze escolas da cidade. Na análise dos dados foram usadas média, erro padrão, teste t de student e análise de variância. Na opinião dos discentes a EA não é abordada com frequência nas disciplinas, apesar de considerarem que seus professores são, na maioria dos casos, aptos para ensinar o tema. Os alunos das escolas privadas obtiveram as melhores notas (75% de acertos e um avanço significativo de conhecimento em EA entre a 1ª e a 3ª série. O mesmo não ocorre nas escolas públicas, demonstrando uma estagnação de conhecimento nesta área ao longo do ensino médio. Os alunos das escolas estaduais acertaram, em média, 73% das questões, enquanto que na rede federal de ensino estes acertaram 67%. O avanço no conhecimento ambiental ao longo da permanência do discente no ensino médio deveria ser melhorado nas escolas, principalmente nas públicas, considerando o aspecto genérico das perguntas do questionário. O fato preocupante foi observar que nas escolas públicas não há avanço de conhecimento nesta área entre a 1ª e a 3ª série. Portanto, é necessária uma abordagem mais efetiva nas práticas desenvolvidas no ambiente escolar relativas as questões ambientais.

Full Text Available A Região Oceânica do município de Niterói (RJ tem sido objeto de intensa especulação imobiliária nas últimas décadas, associando o ideário de paisagens naturais e qualidade de vida a um modelo de habitações predominantemente voltado para população de alto padrão aquisitivo. Neste sentido, este trabalho objetiva analisar a expansão tanto do perímetro urbano como da densidade de domicílios da região no período entre 1976 e 2010, associando ainda a situação atual com o zoneamento urbano-ambiental vigente. A análise histórica, a geoestatística e um conjunto variado de geotecnologias foram as principais ferramentas utilizadas para produção e análise de dados. Em conjunto com estas ferramentas, é proposta uma metodologia alternativa de tratamento de dados censitários e avaliação de densidades de domicílios por unidade de área. Os resultados demonstram o crescimento de 112% da área urbanizada da Região Oceânica, enquanto o número de domicílios cresceu na ordem de 600%, remontando ao processo interligado de avanço tanto via expansão em área quanto via aumento de densidade. Em comparação com o zoneamento, há esgotamento para incorporação de novas áreas perimetrais, o que aponta para um aprofundamento ainda maior do aumento de densidades demográficas nas próximas décadas assim como da pressão sobre os geossistemas costeiros.

Full Text Available Propolis and royal jelly (RJ, two important honeybee products, have been used commonly all over the World as traditional and ethnopharmacological nutrients since ancient times. Both of them have a lot of active ingredients, which are known to be effective for several medical conditions. In this article, medical databases were searched for the usage of RJ and propolis in upper respiratory tract infections (URTI and as a dietary supplementation, together and separately. 10-hydroxy-2-decenoic acid (10-HDA is the most prominent active compound showing antimicrobial effect within RJ. Caffeic acid phenethyl ester (CAPE is the most famous one that shows antimicrobial and anti-inflammatory effect within propolis. When compared with propolis, RJ was found to have richer content for all three main nutrients; proteins, carbohydrates, and lipids. More clinical, experimental, and basic studies are needed to find out the best-standardized mixture to cope with URTI in which RJ and propolis will be main ingredients in addition to the other secondary compounds that have health-beneficial effects.

The protective effect of Royal Jelly (RJ) against the hemopoietic dysfunction in whole body X-irradiated C57BL/6 mice was investigated. When RJ (1.0 g/kg, po or 0.5 g/kg, ip) was administered every day beginning two weeks before X-irradiation (10 Gy), a significant increase in the number of leukocytes and erythrocytes was observed in mice treated with RJ, as compared with X-irradiated control. In addition, the number of colony forming units in culture (CFU-C) of bone marrow cells or splenocytes was significantly increased in mice treated with RJ. Therefore, when granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3) in peripheral blood was measured by ELISA kit, a significant increase in the amount of GM-CSF and IL-3 was observed. These results suggest that the protective effect of RJ against hemopoietic dysfunction could be expressed through an increase in the number of hemopoietic stem cells by the induction of hemopoietic factor such as GM-CSF and IL-3.

Dr. Victor Reis delivered the keynote talk at the closing session of the conference. The talk was forward looking and focused on the importance of advanced computing for large-scale nuclear energy goals such as Global Nuclear Energy Partnership (GNEP). Dr. Reis discussed the important connections of GNEP to the Scientific Discovery through Advanced Computing (SciDAC) program and the SciDAC research portfolio. In the context of GNEP, Dr. Reis talked about possible fuel leasing configurations, strategies for their implementation, and typical fuel cycle flow sheets. A major portion of the talk addressed lessons learnt from ‘Science Based Stockpile Stewardship’ and the Accelerated Strategic Computing Initiative (ASCI) initiative and how they can provide guidance for advancing GNEP and SciDAC goals. Dr. Reis’s colorful and informative presentation included international proverbs, quotes and comments, in tune with the international flavor that is part of the GNEP philosophy and plan. He concluded with a positive and motivating outlook for peaceful nuclear energy and its potential to solve global problems. An interview with Dr. Reis, addressing some of the above issues, is the cover story of Issue 2 of the SciDAC Review and available at http://www.scidacreview.org This summary of Dr. Reis’s PowerPoint presentation was prepared by Institute of Physics Publishing, the complete PowerPoint version of Dr. Reis’s talk at SciDAC 2006 is given as a multimedia attachment to this summary.

To design and evaluate an ET simulator to train Reproductive Endocrinology and Infertility (REI) fellows' techniques of ET. Simulation model development and retrospective cohort analysis. Not applicable. Patients undergoing IVF. Simulation model evaluation and implementation of ET simulation training. Pregnancy rates. The REI fellow and faculty evaluation responses (n = 19/21 [90%]) of the model demonstrated realistic characteristics, with evaluators concluding the model was suitable for training in almost all evaluated areas. A total of 12 REI fellows who performed ET were analyzed: 6 before ET trainer and 6 after ET trainer. Pregnancy rates were 31% in the initial 10 ETs per fellow before simulator vs. 46% after simulator. One of six pre-ET trainer fellows (17%) had pregnancy rates ≥40% in their first 10 ETs; whereas four of six post-ET trainer fellows had pregnancy rates ≥40% in their first 10 ETs. The average number of ETs to obtain >40% pregnancy efficiency was 27 ETs before trainer vs. 15 ETs after trainer. Pregnancy rates were similar in the two groups after 20 ETs, and collective terminal pregnancy rates were >50% after 40 ETs. Embryo transfer simulation improved REI fellow pregnancy rates in their first 10 transfers and led to a more rapid ET proficiency. These data suggest potential value in adopting ET simulation, even in programs with a robust history of live ET in fellowship training. Published by Elsevier Inc.

To compare rates of clinical pregnancy (CPR) and live birth (LBR) following embryo transfer (ET) performed by reproductive endocrinology and infertility (REI) fellows before and after a prolonged lapse in clinical training due to an 18-month research rotation. Retrospective cohort study. Not applicable. All women undergoing in vitro fertilization (IVF) and IVF-intracytoplasmic sperm injection (ICSI) cycles with ET performed by REI fellows from August 2003 to July 2012. Eighteen-month lapse in clinical training of REI fellows. CPR and LBR before and after the lapse in clinical training were calculated and compared per fellow and as a composite group. Alternating logistic regression models were used to calculate the odds of clinical pregnancy and live birth following transfers performed before and after the lapse in training. Unadjusted odds of clinical pregnancy and live birth were similar between the two time periods both for individual fellows and for the composite group. Alternate logistic regression analysis revealed no significant difference in CPR (odds ratio [OR] 0.94, 95% confidence interval [CI] 0.83-1.07) or LBR (OR 1.05, 95% CI 0.94-1.18) after the lapse in training compared with before. A research rotation is common in REI fellowship training programs. This prolonged departure from clinical training does not appear to negatively affect pregnancy outcome following fellow ET.

In the Western honey bee, Apis mellifera, queens and workers have different longevity although they share the same genome. Queens consume royal jelly (RJ) as the main food throughout their life, including as adults, but workers only eat worker jelly when they are larvae less than 3 days old. In order to explore the effect of RJ and the components affecting longevity of worker honey bees, we first determined the optimal dose for prolonging longevity of workers as 4% RJ in 50% sucrose solution,...

Full Text Available Este estudo disponibiliza um levantamento dos dados demográficos do município de Campos dos Goytacazes/RJ, fator imprescindível para o desenvolvimento de estratégias para a pedagogia do envelhecimento. Atualmente, segundo dados do Censo do IBGE (2010,  existem 463.731 pessoas, sendo que o índice de envelhecimento corresponde a 12% da população total. Este segmento etário está aumentando e configura um desenho demográfico que refletirá nos próximos anos em uma maior população idosa. A investigação partiu de uma pesquisa bibliográfica sobre a questão principal que é o envelhecimento populacional. A pesquisa caracteriza-se como de natureza quantitativa. Levando em consideração o objetivo proposto, tem caráter descritivo e exploratório, na qual foram utilizados dados obtidos dos Censos Demográficos e dos Indicadores Sociais do IBGE, do período de 1991 a 2015. Como resultado, pode-se perceber que o crescimento e o envelhecimento demográfico da população indicam  um fenômeno relevante que vem modificando a perspectiva de vida dos indivíduos. O grande desafio que se coloca para a sociedade contemporânea envolve o reconhecimento do ser enquanto sujeito de direitos, dos princípios de independência, participação, dignidade, assistência e autorrealização estabelecidos pela ONU. Nesse sentido, constata-se, principalmente, a relevância da educação, para além de um direito social, mas como possibilidade de mudança de visão em relação ao envelhecimento. Uma pedagogia do envelhecer que envolva uma dinâmica de co-educação(parcerias que proporcione ao idoso a inserção social, o reconhecimento das condições de sobrevivência e garantias de melhor qualidade de vida, dignidade e cidadania.

The objective was to compare the effects of royal jelly (RJ) and eCG treatments on reproductive performance of ewes synchronized using intravaginal progesterone-releasing devices. Forty-two cycling Awassi ewes were treated intramuscularly (i.m.) with 15 mg PGF2alpha. On the following day, all ewes were administered with CIDR-G for 12 days and were randomly allocated to three (RJ, eCG and control) groups of 14 ewes each. Ewes in the RJ-treated group received daily i.m. treatments of 400mg RJ during the period of CIDR-treatment. Each ewe in the eCG-treated group received an i.m. treatment of 500 IU eCG at the time of CIDR-G removal (day 0) and no further treatment was given to ewes in the control group. Ewes were exposed to four fertile rams for 72 h, from the time of CIDR-G removal, and checked for breeding marks at 6-h intervals. Blood samples were collected from day -13 until day 0 and thereafter until day 19 for progesterone analysis. Royal jelly treatment resulted in a greater rate of decline and lower (Pprogesterone concentrations between days -10 and 0 than eCG-treated and control ewes. Expression of estrus was similar among the three groups and intervals to onset of estrus were shorter (P<0.01) in RJ-treated (31.3h) and eCG-treated (29.8h) than control (41.3h) ewes. First-cycle pregnancy and lambing rates were greater (P<0.05) in RJ-treated (71.4 and 71.4%) and eCG-treated (85.7 and 78.6%) than in control (42.9 and 35.7%) ewes, respectively. Results demonstrate that the treatments of RJ and eCG in conjunction with CIDR-G were similarly effective in induction of estrus and improvement of pregnancy and lambing rates.

Histosols in an Upper Montane Environment in the Itatiaia Plateau

Paula Fernanda Chaves Soares

Full Text Available ABSTRACT: Highland environments favor accumulation and preservation of soil organic matter (SOM due to low temperatures, leading to the formation of Histosols. The Itatiaia National Park (INP, Rio de Janeiro, Brazil, offers conditions for preservation of SOM deposited over time, which has led to the formation of these soils. The objective of this study was to characterize Histosols in this environment, with the premise that it may provide evidence of changes in vegetation. Organossolos (Histosols were sampled, characterized, described, and analyzed for their properties, stable isotopes of 12C and 13 14 15 14 C, N and N, and dating of organic matter through C. The soils were classified in the Brazilian Soil Classification System as Organossolo Háplico Hêmico típico - RJ-01 (Haplohemists and Organossolo Fólico Sáprico cambissólico - RJ-02 (Udifolists. The morphological properties, degree of transformation, and chemical fractioning of SOM were consistent with hemic and sapric materials. The δ13C and δ15N isotopic analyses showed a difference in the contribution of plant materials. In RJ-01, there was previous influence of algae, due to poor drainage, and depletion of δ13C, suggesting a mix of C3 and C4 plants. RJ-02 showed influence of C3 type plants. The 14C dating for RJ-01 was 3280±80 years, and for RJ-02, 2005±5 years (modern age.

Full Text Available Abstract Background Vascular endothelial growth factor (VEGF is a key regulator of pathogenic angiogenesis in diseases such as cancer and diabetic retinopathy. Bee products [royal jelly (RJ, bee pollen, and Chinese red propolis] from the honeybee, Apis mellifera, have been used as traditional health foods for centuries. The aim of this study was to investigate the anti-angiogenic effects of bee products using human umbilical vein endothelial cells (HUVECs. Methods In an in vitro tube formation assay, HUVECs and fibroblast cells were incubated for 14 days with VEGF and various concentrations of bee products [RJ, ethanol extract of bee pollen, ethanol extract of Chinese red propolis and its constituent, caffeic acid phenethyl ester (CAPE]. To clarify the mechanism of in vitro angiogenesis, HUVEC proliferation and migration were induced by VEGF with or without various concentrations of RJ, bee pollen, Chinese red propolis, and CAPE. Results RJ, bee pollen, Chinese red propolis, and CAPE significantly suppressed VEGF-induced in vitro tube formation in the descending order: CAPE > Chinese red propolis >> bee pollen > RJ. RJ and Chinese red propolis suppressed both VEGF-induced HUVEC proliferation and migration. In contrast, bee pollen and CAPE suppressed only the proliferation. Conclusion Among the bee products, Chinese red propolis and CAPE in particular showed strong suppressive effects against VEGF-induced angiogenesis. These findings indicate that Chinese red propolis and CAPE may have potential as preventive and therapeutic agents against angiogenesis-related human diseases.

Full Text Available The objective of the present study was to investigate selected trace and mineral elements in Royal Jelly (RJ from Bulgaria. A total of 30 RJ samples were included in the study. The analytical procedure consisted of the microwave digestion of the RJ samples with nitric acid followed by instrumental measurement. Concentrations of Al, Ba, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, P, Sr and Zn were determined using inductively coupled plasma optical emission spectroscopy (ICP-OES, while As, Cd, Co, Ni and Pb were determined by electrothermal atomic absorption spectrometry (ETAAS. Our results showed that elements K, Mg, Ca represented 96% from the total mineral content of the RJ samples from Bulgaria, while the most abundant trace element was Na, followed by Zn. The elements Ba, Cr, Cu, Fe, Mn and Sr were found in trace concentration levels and elements As, Pb, Cd, Co and Ni in microconcentration levels. Selected mineral and trace elements were found in relatively constant concentration levels in all of the analyzed RJ samples. It was concluded that chemical element content did not depend on geographical origin and was under homeostatic adjustment in RJs.

2015-07-01

Standardized, high-quality training in reproductive endocrinology, infertility, and assisted reproductive technologies (REI-ART) faces challenges owing to the high-tech nature of ART and the important country-to-country differences in clinical practice and regulations overseeing training. Moreover, while the training capacity of the classical by-fellowship training platforms is shrinking, an increasing demand for REI-ART specialists is coming from emerging countries. To meet this expanding need for REI-ART specialists, we propose a novel by-network model linking a reference training center to satellite practical training sites. Simulation should be used more extensively to achieve competency before initiating live clinical experience, analogous to the highly effective training systems that have been used in aviation for decades. Large ART databases that exist because of obligations to report ART activity and results constitute unique yet so far untapped sources for developing by-scenario simulation training models. Online training materials incorporating these state-of-the-art information technology tools could be developed as a means of fulfilling training needs worldwide. Copyright © 2015.

Full Text Available Os problemas de inundações no município de São Gonçalo (RJ são cada vez mais comuns. Esta realidade é favorecida pelas condições geográficas do município somadas à intensa ocupação urbana. O agravamento das inundações também pode estar relacionado ao nível de percepção e compreensão da população em relação ao funcionamento de rios e bacias hidrográficas. O desconhecimento da dinâmica ambiental atinge também as escolas, onde o conceito de bacia hidrográfica não está sendo devidamente repassado e discutido dentro de ações de Educação Ambiental. Diante deste quadro, o presente trabalho se propôs a investigar a percepção ambiental em relação aos rios e bacias hidrográficas urbanizadas, de alunos do Ensino Básico de escolas públicas situadas em duas bacias hidrográficas que apresentam intensa degradação e descaracterização de seus rios. Para tanto, 80 estudantes foram entrevistados, percebendo-se que os mesmos não possuem conhecimento sistematizado acerca das bacias hidrográficas, o que contribui para o pouco compromisso com a preservação ambiental. A execução dessa proposta de pesquisa permitiu uma reflexão sobre as formas de abordagem do conteúdo escolar sobre rios e bacias hidrográficas.

Full Text Available The aim of this study was to evaluate litter input and decomposition and root biomass of three forest fragments at different successional stages (advanced, medium and initial in Pinheiral Municipality, in the state of RJ, Brazil. To evaluate litter input, 10 conic collectors were installed in each fragment. The root biomass was quantified by monolith method in two periods (wet and dry at depths of 0-10, 10-20 and 20- 30 cm, and 10 samples were collected in each area. To evaluate the decomposition rate in each area, 12 litter bags were distributed. No significant differences were observed for litter input between the areas, but there was a tendency to increase litter input with successional evolution. No significant differences were observed for seasonal litter input between areas during the year, but there was a small increase in the months of July and August. At the advanced stage, litter input could be grouped into two periods: February to July, with lower values; and August to January, with higher values. The leaf fractions and reproductive material input were reduced, while branch and other fractions increased with succession. For litter decomposition, the intermediate stage showed the lowest decomposition constant (k (0.0038 g g -1day-1 and the highest half life time (182 days , followed by the initial (0044 g g -1day-1 and 154 days and advanced (0.0064 g g -1day-1 and 108 days stages. The root biomass in different areas and depths for both two periods studied showed higher values in the advanced stage, followed by the intermediate stage and the lowest values were found in the initial stage. The seasonal root biomass difference occurred mainly in the intermediate stage, with higher values in June.

Full Text Available The traditional onion (Allium cepa hybrid production requires the development of maintainer and male sterile lines and also a pollinator line with good specific combination ability. We report the identification of maintainer and male-sterile onion lines within the Brazilian 'Baia Periforme' derived population, 'Alfa São Francisco', associating random field pairing of male-fertile plants with selected male-sterile plants and PCR-based marker system monitoring S, T and N-cytoplasms. Male-sterile plants produced flowers with light green anthers which were easily detected in the field. A frequency of 2.0% of male-sterile plants was estimated in the 'Alfa São Francisco' sampled population. Male-sterile plants produced the 5'cob-marker 180-bp and the orfA501-marker 473-bp fragments, suggesting the T-cytoplasm type, while the maintainer line produced only the 5'cob-marker 180-bp. These identified lines will be important to develop tropical onion hybrids well-adapted to Brazilian low latitudes and to future comparative studies with other onion cytoplasmic genic male sterility systems.A produção tradicional de híbrido de cebola (Allium cepa requer o desenvolvimento de linhas mantenedoras e linhas macho estéreis, bem como uma linha polinizadora de boa capacidade específica de combinação.

The aim of this study was to investigate the immediate effects of trunk stabilization exercise (SE) and conventional trunk exercise (CE) programs on jump performance. 13 adolescent male soccer players performed 2 kinds of jump testing before and immediate after 3 experimental conditions: SE, CE, and non-exercise (NE). The SE program consisted of the elbow-toe, hand-knee, and back bridge, and the CE program consisted of the sit-up, sit-up with trunk rotation and back extension. Testing of a countermovement jump (CMJ) and rebound jump (RJ) were performed to assess jump performance. Jump height of the CMJ and RJ-index, contact time, and jump height of the RJ were analyzed. The RJ index was improved significantly only after SE (p=0.017). However, contact time and jump height did not improve significantly in the SE condition. Moreover, no significant interaction or main effects of time or group were observed in the CMJ. Consequently, this study showed the different immediate effect on the RJ between the SE and CE, and suggested the possibility that the SE used in this study is useful as a warm-up program to improve the explosive movements. © Georg Thieme Verlag KG Stuttgart · New York.

To illustrate, through internal industry documents, how RJ Reynolds exploited the concerns of the Japanese society about cleanliness to market the concept of cleaner, implicitly healthier cigarettes in Japan. Systematic keyword and opportunistic website searches of formerly private internal industry documents. Industry documents show that RJ Reynolds developed marketing plans based upon their cultural assumptions of Japanese people as fastidious about hygiene and manners, and with relatively high penchants to try new products. RJ Reynolds found there was also a growing concern for health, the environment, and smokers were conscious about annoying others. Deodorised consumer products were one of Japan's biggest trends. These characteristics presented RJ Reynolds with a profitable formula for marketing Salem Pianissimo, a clean cigarette with less smell and smoke. Salem Pianissimo, a 100 mm cigarette claiming to contain 1 mg tar and 0.1 mg nicotine, targeted women since menthol cigarettes were popular among 18-24 year old female smokers, although Japan's law prohibited those below 20 years to smoke and the tobacco industry had a voluntary code disallowing advertising to women and youth. RJ Reynolds successfully launched its clean cigarette, Salem Pianissimo, in Japan aiming to exploit perceived cultural characteristics such as a penchant for cleanliness, an eagerness to try new products, and social harmony.

Bergseth, Kathleen J; Bouffard, Jeffrey A

2013-09-01

Restorative justice (RJ) programs have become widespread in the United States and in other countries. These programs are often seen as a viable alternative to traditional retributive processing, especially for minor, and sometimes more serious, forms of delinquency and adult criminality. The programs hold promise for achieving several goals, including increased community and victim involvement, greater satisfaction with the case outcomes, improved offender compliance, increased perceptions of fairness, and even recidivism reduction. Meta-analyses have demonstrated varying degrees of program success in recidivism reduction, which may in part reflect differential effectiveness of the RJ approach for various kinds of offenders. This study examined whether an RJ program for juvenile offenders had differential impacts on recidivism across various offender characteristics (including age, gender, racial group, offending history, and current offense). Results generally support the effectiveness of the program for many types of offenders. Implications for future research and potential improvements to the RJ model are discussed.

Occupational safety and health practices among flower greenhouses workers from Alto Tietê region (Brazil)

International Nuclear Information System (INIS)

Ribeiro, Marcela G.; Colasso, Camilla G.; Monteiro, Paula P.; Filho, Walter R. Pedreira; Yonamine, Maurício

2012-01-01

In this preliminary study the occupational safety and health practices among flower greenhouses workers were evaluated. The study was carried out in the alto Tietê region, located at the Sao Paulo State, Brazil. Inadequate welfare facilities; poor pesticide storage, use and disposal conditions; use of highly toxic pesticides; lack of adequate data regarding pesticide use; and incorrect use and maintenance of PPE were observed in most of the visited greenhouses. These results suggest that, in greenhouses, workers may be at higher risk of pesticide exposure, due to many factors that can intensify the exposure such as the lack of control on reentry intervals after pesticide application. Specific regulations are needed to ensure better OSH practices on pesticide use and to improve working conditions in greenhouses, in order to deal with the peculiarities of greenhouse working environment. Some of the special requirements for greenhouses workers' protection are the establishment of ventilation criteria for restricted entry interval; clear reentry restrictions; and EPI for workers other than applicators that need to enter the greenhouse before expiring REI interval. Another important way to improve OSH practices among workers includes the distribution of simple guidelines on the dos and don'ts regarding OSH practices in greenhouses and extensively training interventions to change the perception of hazards and the behavior towards risk. - Highlights: ► Occupational safety and health practices among flower greenhouses workers were evaluated. ► Lack of clear reentry restrictions can intensify the exposure in greenhouses. ► Specific regulations dealing with the peculiarities of greenhouse working environment are needed. ► Distribution of simple guidelines relying on greenhouse working can improve OSH practices. ► Training interventions are important to change the workers' perception of hazards and behavior towards risk.

The present study was undertaken to investigate the protective effect of royal jelly (RJ) against toxicity induced by a synthetic pyrethroid insecticide, lambda-cyhalothrin (LCT), in Swiss albino mice. Animals were randomly divided into six groups of six animals each. The control group received distilled water alone, whereas mice in the treatment groups received RJ alone (100 or 250 mg/kg of body weight), LCT alone (668 ppm), or RJ+LCT for 21 days. All mice (100%) survived until the end of experiment and were sacrificed at the end of 24 hours. Blood, bone marrow, and liver and kidney tissues were analyzed for aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), creatinine, malondialdehyde (MDA), and reduced glutathione (GSH) levels and micronucleus (MN) frequency, chromosomal aberrations (CAs), and pathological damages. Serum AST, ALT, BUN, and creatinine levels were elevated in mice treated with LCT alone compared with the other tested groups (P<.05). LCT-induced oxidative damage caused a significant decrease in GSH levels and a significant rise in MDA levels of liver and kidney tissues. LCT alone-treated mice presented higher frequencies (P<.05) of MNs, CAs, and abnormal metaphases compared with the controls; moreover, the mitotic index was lower than in controls (P<.05). Oral treatment with RJ significantly ameliorated the indices of hepatotoxicity, nephrotoxicity, lipid peroxidation, and genotoxicity induced by LCT. Both doses of RJ tested provided significant protection against LCT-induced toxicity, and its strongest effect was observed at the dose level of 250 mg/kg of body weight. In vivo results suggest that RJ is a potent antioxidant against LCT-induced toxicity, and its protective effect is dose dependent.

Among royal jelly's (RJ) various biological activities, its possible antitumour activity deserves particular attention. The purpose of this study was to investigate the influence of RJ, its bioactive component 10-hydroxy-2-decenoic acid (10- HDA), and human interferon-alpha (HuIFN-αN3) on the proliferation of human colorectal adenocarcinoma cells (CaCo- 2), and ascertain their effect on intracellular glutathione (GSH) level and lipid peroxidation. We studied the antiproliferative (AP) activity of RJ [(0.1 g/10 mL phosphate buffer saline (PBS)], HuIFN-αN3 (1000 I.U. mL⁻¹), 10-HDA at 100.0 μmol L⁻¹, and their different combinations, in the ratio 1:1, 1:2, and 2:1 on CaCo-2 cells. The GSH level was measured by glutathione assay. The lipid peroxidation was measured by malondialdehyde (MDA) assay. Single RJ had a low AP activity: 2.0 (0.5 mg mL⁻¹). HuIFN-αN3 had an AP activity of 2.5 (208.33 I.U. mL⁻¹), while 10-HDA had an AP activity of 1.5 (37.5 μmol mL⁻¹). The highest AP activity of 3.8 was obtained when RJ and HuIFN-αN3 were applied at the ratio 2:1. In that combination the level of GSH was 24.9±2.4 nmol g⁻³ of proteins (vs. 70.2±3.2 nmol g⁻³ in the control) and the level of MDA was 72.3±3.1 nmol g⁻³ (vs. 23.6±9.1 nmol g⁻³ in the control). It is generally assumed that 10-HDA, an important constituent of RJ, together with HuIFN-αN3, is responsible for the inhibition of CaCo-2 cells proliferation in vitro. In our study, however, RJ and HuIFN-αN3 applied at 2:1 decreased the level of GSH the most and significantly increased lipid peroxidation via MDA in CaCo-2 cells. Future studies should show whether these GSH- and MDA-related activities of RJ, HuIFN-αN3, 10-HDA, and their combinations may decrease the tumorigenicity index and tumorigenic potential of various tumour cells in vitro.

Methods: This was a retrospective study of patients diagnosed with retinoblastoma in Hospital São João, between 1978 and 2012. Results: Fifty patients with retinoblastoma were evaluated in our institution between 1978 and 2012. Four patients were excluded due to loss of follow-up. Among the 46 retinoblastoma cases, 33 (71.7% were unilateral and 13 (28.3% bilateral, with a mean age at diagnosis of 22.19 months and 6.92 months, respectively (P<0.001. Leukocoria was the most common presenting sign (36.9%, followed by strabismus (19.6%, a combination of leukocoria and strabismus (8.7%, and buphthalmia (2.2%. Between 1978 and 1992, nine retinoblastoma cases were referred to our hospital, all of them unilateral, and, in each case, enucleation was performed, with or without salvage therapy. Between 1993 and 2012, 18 eyes with retinoblastoma were successfully managed with conservative treatment. Conclusion: Demographic results were generally coincident with previous reports. It is crucial to screen leukocoria in pediatric practice, even in asymptomatic children. The outcome of retinoblastoma treatment in our hospital is similar to other series in developed countries.

We measure basic network parameters of silvernanowire (AgNW) networks commonly used as transparent conductingelectrodes in organic optoelectronic devices. By means of four point probing with nanoprobes, the wire-to-wire junction resistance and the resistance of single nanowires are measured. The resistanceRNW of a single nanowire shows a value of RNW=(4.96±0.18) Ω/μm. The junction resistanceRJ differs for annealed and non-annealed NW networks, exhibiting values of RJ=(25.2±1.9) Ω (annealed) and RJ=(529±239) Ω (non-annealed), respectively. Our simulation achieves a good agreement between the measured network parameters and the sheet resistanceRS of the entire network. Extrapolating RJ to zero, our study show that we are close to the electrical limit of the conductivity of our AgNW system: We obtain a possible RS reduction by only ≈20% (common RS≈10 Ω/sq). Therefore, we expect further performance improvements in AgNW systems mainly by increasing NW length or by utilizing novel network geometries.

Antidepressant-Like Activity of 10-Hydroxy-Trans-2-Decenoic Acid, a Unique Unsaturated Fatty Acid of Royal Jelly, in Stress-Inducible Depression-Like Mouse Model

Full Text Available Symptoms of depression and anxiety appeared in mice after they had been subjected to a combination of forced swimming for 15 min followed by being kept in cages that were sequentially subjected to leaning, drenching, and rotation within 1-2 days for a total of 3 weeks. The animals were then evaluated by the tail-suspension test, elevated plus-maze test, and open-field test at 1 day after the end of stress exposure. Using these experimental systems, we found that 10-hydroxy-trans-2-decenoic acid (HDEA, an unsaturated fatty acid unique to royal jelly (RJ, protected against the depression and anxiety when intraperitoneally administered once a day for 3 weeks simultaneously with the stress loading. Intraperitoneally administered RJ, a rich source of HDEA, was also protective against the depression, but RJ given by the oral route was less effective. Our present results demonstrate that HDEA and RJ, a natural source of it, were effective in ameliorating the stress-inducible symptoms of depression and anxiety.

Resistance to the mainlandization of criminal justice practices: a barrier to the development of restorative justice in Hong Kong.

Science.gov (United States)

Lo, T Wing

2012-06-01

This article examines the political and legal barriers to introducing restorative justice (RJ) in Hong Kong. It argues that the processes involved in RJ may be in conflict with the rule of law, which is regarded by the citizens of Hong Kong as sacrosanct in their resistance to the "mainlandization" of criminal justice practices after China resumed sovereignty of Hong Kong. It is argued that, because it could admit such potentially harmful Chinese criminal justice concepts as "rule by the people," "absence of the presumption of innocence," "leniency for self-confession and severity for resistance," and "toeing the party line," RJ would be devoid of any restorative substance and could breach the principles of due process.

Specific Full Scope Simulators are an essential tool for training NPP control room operators, in the formation phase as well as for maintaining their qualifications. In the last years availability of a Plant specific simulator has also become a Regulator requirement for Nuclear Power Plant operation. By providing real-time practical training for the operators, the use of a simulator allows improving the operator's performance, reducing the number of unplanned shutdowns and more effective response to abnormal and emergency operating conditions. It can also be used, among other uses, to validate procedures, test proposed plant modifications, perform engineering studies and to provide operation training for the technical support staff of the plant. The NPP site, in Angra dos Reis-RJ, Brazil, comprises the two units in operation, Unit 1, 640 MWe, Westinghouse PWR and Unit 2, 1350 MWe, KWU/Areva PWR and one unit in construction, Unit 3, 1405 MWe, KWU/Areva PWR, of the same design of Angra 2. Angra 2 has had its full scope simulator from the beginning, however this was not the case of Angra 1, that had to train its operators abroad, due to lack of a specific simulator. Eletronuclear participated in all the phases of the project, from data supply to commissioning and validation. The Angra 1 full scope simulator encompasses more than 80 systems of the plant including the Primary system, reactor core and associated auxiliary systems, the secondary system and turbo generator as well as all the Plant operational and safety I and C.

2010-01-01

This study has the aim to assess the impact of accidental release of tritium postulate from a nuclear power reactor through environmental modeling of aquatic resources. In order to do that it was used computational models of hydrodynamics and transport for the simulation of tritium dispersion caused by an accident in a CANDU reactor located in the ongoing Angra 3 site. This exercise was accomplished with the aid of a code system (SisBAHIA) developed in the Rio de Janeiro Federal University (COPPE/UFRJ). The CANDU reactor is one that uses heavy water (D 2 O) as moderator and coolant of the core. It was postulated, then, the LOCA (Loss of Coolant Accident) accident in the emergency cooling system of the nucleus (without fusion), where was lost 66 m 3 of soda almost instantaneously. This inventory contained 35 PBq and was released a load of 9.7 TBq/s in liquid form near the Itaorna beach, Angra dos Reis - RJ. The models mentioned above were applied in two scenarios (plant stopped and operating) and showed a tritium plume with specific activities larger than the reference level for seawater (1.1 MBq/m 3 ) during the first 14 days after the accident. The main difference between the scenario without and with seawater recirculation (pumping and discharge) is based on the enhancement of dilution of the highest concentrations in the last one. This dilution enhancement resulting in decreasing concentrations was observed only during the first two weeks, when they ranged from 1x10 9 to 5x10 5 Bq/m 3 close to the Itaorna beach spreading just to Sandri Island. After 180 days, the plume could not be detected anymore in the bay, because their activities would be lower than the minimum detectable value ( 3 ). (author)

2011-03-01

We have developed a multi-probe resonance-frequency electrical impedance spectroscope (REIS) system to detect breast abnormalities. Based on assessing asymmetry in REIS signals acquired between left and right breasts, we developed several machine learning classifiers to classify younger women (i.e., under 50YO) into two groups of having high and low risk for developing breast cancer. In this study, we investigated a new method to optimize performance based on the area under a selected partial receiver operating characteristic (ROC) curve when optimizing an artificial neural network (ANN), and tested whether it could improve classification performance. From an ongoing prospective study, we selected a dataset of 174 cases for whom we have both REIS signals and diagnostic status verification. The dataset includes 66 "positive" cases recommended for biopsy due to detection of highly suspicious breast lesions and 108 "negative" cases determined by imaging based examinations. A set of REIS-based feature differences, extracted from the two breasts using a mirror-matched approach, was computed and constituted an initial feature pool. Using a leave-one-case-out cross-validation method, we applied a genetic algorithm (GA) to train the ANN with an optimal subset of features. Two optimization criteria were separately used in GA optimization, namely the area under the entire ROC curve (AUC) and the partial area under the ROC curve, up to a predetermined threshold (i.e., 90% specificity). The results showed that although the ANN optimized using the entire AUC yielded higher overall performance (AUC = 0.83 versus 0.76), the ANN optimized using the partial ROC area criterion achieved substantially higher operational performance (i.e., increasing sensitivity level from 28% to 48% at 95% specificity and/ or from 48% to 58% at 90% specificity).

Full Text Available Epilepsy is one of the most common neurological diseases affecting at least 50 million people worldwide. Valproic acid (VPA is a widely used antiepileptic medication for both generalized and partial seizures of epilepsy. The objective of the study was to investigate the anti-mutagenic and anti-histopathologic effects of royal jelly (RJ on VPA-induced genotoxicity and nephrotoxicity in male albino mice (Mus musculus. 80 Mice were used for 21 days; they were divided into eight groups, (G1 served as normal control group, G2 received VPA (100 mg/kg and (G3–G5 received RJ at doses 50, 100 and 200 mg/kg respectively. While (G6–G8 were administrated RJ simultaneously with VPA. In RJ treated mice at doses of 50 and 100 mg/kg, the kidney sections showed normal histological structure with non significant changes in chromosomal aberrations (CA and mitotic index (MI, while RJ at dose of 200 mg/kg showed mild inflammatory cells infiltration and hyperemic glomeruli but not highly significant changes in CA and MI. The cortex of VPA treated mice revealed congested glomeruli with inflammatory cells infiltration, and marked degeneration of almost structures of the glomeruli including some vacuoles in mesangial cells with dark mesangial substances on the ultrastructure level. Some proximal tubules showed degeneration of microvilli on the apical parts of some cells. Cells of the distal tubules attained obliterated lumen and vacuolated lining epithelium. The results also revealed that valproic acid induced a high frequency of CA in bone marrow cells of mice and MI was significantly decreased indicating bone marrow cytotoxicity. The treatment of mice with RJ at doses 50, 100 and 200 mg/kg for 21 days simultaneously with VPA resulted in abating the histological alterations in renal tissues with significant reduction in chromosomal aberrations, for doses of 50 and 100 mg/kg, and elevation in mitotic index (P < 0.05.

Studies around the management and disposal of radioactive waste have been conducted for decades. In Brazil, the National Nuclear Energy Commission (CNEN) is responsible for Intermediate Radioactive Waste deposits, located in Fundao Island, Rio de Janeiro (RJ). According to CNEN 8.01 norm, it is necessary to characterize and to study the location area around the deposit. Within this context, the objective of this study was to characterize the Canal Cunha Basin, the western of Guanabara Bay and study the Environmental Impact, with determination of heavy metals (Pb, Cu, Cd, Zn and Ni) in said river basin and bay. The work involves collecting water and sediment samples in five georeferenced points. The sediment samples was collected using the EPA Method 3051 and the reading of the concentrations of heavy metals in water and sediment was performed by ICP-OES. Maps were generated for characterization and spatial distribution of these metals on Canal Cunha Basin. The Canal Cunha's drainage composes a territory with 62.85 km 2 (approximated area) and 37.01 km of perimeter The high occupancy rates in the urban area that decrease the rate of infiltration and changes in physiography caused by construction of embankments because a reverse behavior expected, which increases the runoff coefficient of 0.74. The results show that in periods of high river discharge, there is a drift of large amounts of Pb, Cu and Cd to the waters of the Canal Cunha and Guanabara Bay. Zn and Ni presented higher concentrations in the dry season. The Pb, Cu, Cd, Zn and Ni concentrations are smaller than the concentrations found in the sediment. This probably happens because Cunha Canal Basin and western of Guanabara Bay receive high organic load, and also because of the high percentage of fine sediment in this, thus promoting the adsorption of metals, not contaminating the water and thus not reaching the food chain.

Full Text Available Background and Objectives: Phenylhydrazine (PHZ, as a known hemolytic agent, causes toxicity in different tissues at various levels. The aim of the current study was to examine the possible protective effects of royal jelly (RJ against PHZ-induced histological injuries of small intestine in mice.   Methods: In this experimental study, adult male mice were randomly divided into four groups of 8 mice each. PHZ was administered intraperitoneally to two groups of mice (at a dose of 60mg/kg every 48 hours for 35 days. One of the groups received RJ (100mg/kg orally 4 hours before PHZ administration. The third group only received RJ, and the forth group was considered as control. Twenty-four hours after the last treatment, different segments of small intestine were dissected out, then histological sections were prepared and quantitative morphometric assessments were performed. To compare the groups, one-way ANOVA and multiple comparative Tukey tests were used. The significance level was considered to be p<0.05.   Results: In this study, PHZ caused significant decreases in depth of duodenal crypts, distribution rate of the goblet cells in ileal villi, width of duodenal and jejunal villi, and height of villi in all three segments of small intestine. Co-administration of RJ partially improved the changes in the above parameters.   Conclusion: From results of this study, it seems that RJ as a free radical scavenger could reduce PHZ-induced intestinal toxicity in mouse.

Full Text Available Royal jelly (RJ is used as a revitalizing tonic. In order to avoid rejection to its acid taste, it is added to honey. There are regulations for honey and for royal jelly separately but not for the mixture. The objective of this work is, therefore, to verify if the same methods used for pure honey quality control can be used for honey mixed with royal jelly and also the presence of RJ through 10-HDA determination. The methods used were: moisture, reducing sugars, apparent sucrose, ash, hydroxymethylfurfural, insoluble solids, diastase activity, acidity and 10-HDA. Samples were prepared by adding 0-100% of RJ in honey. The results showed that the ash method was the only suitable one to all the samples. The acidity analysis (direct titration was suitable to 0-30%RJ samples; the reducing sugar analysis was suitable to 0-20% RJ samples. Concerning moisture analysis the refractometric method is suitable to 0-10% RJ and the Infra Red method is suggested to be used for samples with more than 10% RJ. The methods for diastase activity, HMF, apparent sucrose and insoluble solids were inadequate for all samples with RJ. The presence of RJ in the samples was confirmed by the 10-HDA analyses.A geléia real (GR é utilizada como produto revitalizante com sabor ácido e adstringente. Para evitar rejeição a este sabor, existem misturas de mel com GR. Existe legislação específica para o mel e para a GR separadamente, mas não para a mistura. Os objetivos do trabalho são: verificar se os métodos usados para o controle de qualidade do mel puro podem ser utilizados no controle do mel com GR e verificar a presença de GR pela determinação do 10-HDA. As análises incluíram: umidade, açúcares redutores, sacarose aparente, cinzas, hydroxymethylfurfural, sólidos insolúveis, atividade diastásica, acidez e 10-HDA. As amostras foram preparadas com 0-100% de GR no mel. Os resultados obtidos sugerem que dos métodos citados na legislação do mel somente o de

2013-07-01

Full Text Available A prática de utilizar elementos da natureza com finalidade de auxiliar o homem já é bastante antiga. Desde os tempos primitivos, plantas, animais e elementos químicos fazem parte dos “medicamentos” que o homem utiliza. Com o passar do tempo, baseado no conhecimento do homem, surgiram pesquisas a fim de verificar o potencial de certas plantas, a partir daí surgiram os fármacos compostos de matéria prima vegetal, pois surgiram do isolamento de alguns extratos vegetais. O objetivo deste trabalho é fazer um levantamento de dados a fim de obtermos informações sobre a prescrição de tratamentos à base de plantas medicinais e fitoterápicos por médicos do SUS (Sistema Único de Saúde, do município de Teresópolis, RJ. Foram entrevistados 18 médicos de diferentes especialidades, do ambulatório do UNIFESO. Do total de entrevistados, 83,3%, afirmou acreditar no potencial dos medicamentos à base de plantas medicinais e apoia o uso destes medicamentos, mas a maioria, 94,4%, diz não conhecer o programa, que é exatamente o que regulamenta o uso de plantas medicinais, e possui um “banco de dados” das plantas que tem sua “confiabilidade” verificada. O fato de a maioria dos médicos não terem conhecimento sobre o programa nacional de plantas medicinais, é algo preocupante, pois foi possível perceber na realização desta pesquisa, que alguns consideram o uso de plantas, ou de medicamentos à base de plantas medicinais uma forma de tratamento com menos efeitos colaterais, porém esta falta de informação sobre o programa não garante uma relação risco-benefício favorável. Assim, é de total importância que médicos formados e acadêmicos conheçam o programa nacional de plantas medicinais para uma possível implantação de programas que incentivem o de tratamentos à base de plantas medicinais pelo SUS como uma alternativa mais viável.

Privilegiamos a fala e o ponto de vista dos próprios trabalhadores sobre o movimento, com base no enfoque dos estudos qualitativos e da investigação participativa. Sob a égide do método da educação popular, realizamos reuniões de grupo pautadas na colaboração entre trabalhadores e pesquisadores, o que se mostrou uma estratégia pedagógica facilitadora da reconstrução dos vínculos de solidariedade e da promoção da saúde. Desenvolvemos o argumento de que as práticas de educação em saúde, relativas ao mundo do trabalho, exigem socialização das informações e do conhecimento científico, aliadas a uma ação política integrada que potencialize transformações a favor de uma cidadania plena no trabalho. Outrossim, sustentamos o caráter imprescindível de alguns elementos para a concretização, a contento, de uma práxis educativa em saúde dos trabalhadores, a saber: participação, diálogo, solidariedade e aliança entre trabalhadores e pesquisadores. Por fim, enfatizamos o valor das redes - nas esferas nacional e internacional - de apoio aos trabalhadores no fortalecimento do movimento de banimento do amianto, como também o fato de o próprio trabalho ser um importante ativador da organização de luta pela saúde.In this article we analyze the movement of a solidarity action group named Brazilian Association of the Exposed to Asbestos of Rio de Janeiro (ABREA/RJ.

Full Text Available Trans-10-hydroxy-2-decenoic acid (10-H2DA, 10-hydroxydecanoic acid (10-HDAA, and sebacic acid (SEA are the three major fatty acids in royal jelly (RJ. Previous studies have revealed several pharmacological activities of 10-H2DA and 10-HDAA, although the anti-inflammatory effects and underlying mechanisms by which SEA acts are poorly understood. In the present study, we evaluated and compared the in vitro anti-inflammatory effects of these RJ fatty acids in lipopolysaccharide-stimulated RAW 264.7 macrophages. The results showed that 10-H2DA, 10-HDAA, and SEA had potent, dose-dependent inhibitory effects on the release of the major inflammatory-mediators, nitric oxide, and interleukin-10, and only SEA decreased TNF-α production. Several key inflammatory genes have also been modulated by these RJ fatty acids, with 10-H2DA showing distinct modulating effects as compared to the other two FAs. Furthermore, we found that these three FAs regulated several proteins involved in MAPK and NF-κB signaling pathways. Taken together, these findings provide additional references for using RJ against inflammatory diseases.

Full Text Available The State Park of Ilha Grande is only a part (5,594 hectares of the entire island (19,300 hectares which is located off the south coast of Rio de Janeiro state, between the cities of Mangaratiba and Angra dos Reis. Approximately half of the Park area (47% is covered by dense Atlantic forest. The secondary forest growth is in a process of ecological succession close to attaining maturity (43% and the remaining part (10% is composed of human-altered areas (1%, rocky outcrops with herbaceous vegetation (7%, mangroves and beaches (2%. The fauna is well represented but already shows signs of degradation with introduced species. The analysis of the degree of threat has shown that the dense forest habitat has a relatively stable status of conservation while the secondary forest, the mangrove and the herbaceous vegetation on rocky outcrops (and their fauna are categorized as vulnerable. The area altered by human occupation is considered threatened. Since the coastal area where Ilha Grande is located is well known for its beautiful scenery (known as the green coast, because of the contrast between the ocean and the Atlantic forest covering the Serra do Mar mountain chain. There is a strong possibility for tourism to become the means in which to achieve economic sustainability for conservation. Contradictorily, tourism is also the major threat to local biodiversity and its landscape units. Because tourism is not organized and controlled, during high season the numbers grow above local capacity, giving rise to a proliferation of hotels, guesthouses and camping grounds. The resulting untreated open sewage, random garbage disposal and other harmful activities form the major threats to biodiversity.O Parque Estadual da Ilha Grande é somente uma parte (5.594 hectares de toda a ilha (19.300 hectares localizada na costa sul do Estado do Rio de Janeiro, entre as cidades de Mangaratiba e Angra dos Reis.

it was investigated the transport of the series natural radionuclides and the earth rare light elements in a coastal lagoon system, located in a monazite rich region, in the coast north region of Rio de Janeiro state. The lagoon water showed off abnormal concentrations of radium isotopes and of the earth rare light elements (ERLEs). The longitudinal gradient of the Ra, of the ERLEs and of the major ion concentration's, whose data were obtained during two and half years of the research at the place, and the statistical analysis pointed to two mainly source as responsible for the water lagoon composition - the marine and the underground waters. The underground water supplies the radionuclides and ERLEs, possibly originated by monazite lixiviation. Based on the water speciation modeling, the results of laboratory adsorption on sediment experiments and the sediment characterization, the behavior of the radio isotopes, the ERLEs, U, Th e Pb-210, along of the lagoon, are discussed. It is also discussed the role of the aquatic macrophyte Typha dominguesis Pers in the nuclide uptake and the following liberation. (author)

Guimaraes, J.R.; Penna-Franca, E.

1985-01-01

As part of a broad research program on the behaviour of critical radionuclides to be discharged into the sea by the first Brazilian nuclear power plant, the uptake, accumulation and loss of 137 Cs, 60 Co and 125 I by locally abundant seaweed species was studied. Uptake in static 12 liter aquarium experiments reached apparent steady-state in 2 to 7 days ( 60 Co and 125 I), or 2 to 3 weeks ( 137 Cs). Elimination followed a reverse pattern, being comparatively fast for 137 Cs and slow for 60 Co and 125 I. Dry weight bioaccumulation factors (BFs) were variable, falling in the 10 1 range for 137 Cs, 10 3 for 125 I and 10 3 to 10 4 for 60 Co. Various short-term experiments, performed over a 16 month period, showed marked temporal variations of 60 Co BFs for all species. The results demonstrated that the studied species may play an important role in the transfer of the critical radionuclides through local food webs and can be employed as useful monitors for routine or accidental radionuclide releases.

Foram incluídas 18 gestantes e oito puérperas (n=26, sendo sete adolescentes e 19 adultas; primíparas e multíparas. Para as mulheres, comer e assistir à televisão, comer fora de casa e comer com parentes e amigos no fim de semana eram formas de associar lazer à comida, aumentando o prazer por ela. A renda foi apontada como a principal barreira para o consumo de alimentos saudáveis, que era prioridade das crianças. Por esses motivos, leite, verduras, legumes e frutas eram pouco consumidos. A dieta era composta basicamente por arroz, feijão e frango. Houve preferência por "besteiras". As mulheres estavam submetidas a uma alimentação monótona. Ressalta-se a importância da compreensão e valorização das questões socioculturais e econômicas que influenciam as práticas alimentares, a fim de que a orientação alimentar e nutricional, visando à alimentação saudável, possa ser negociada e ajustada às necessidades e à subjetividade das mulheres grávidas.This study aimed to analyze the self-reported eating practices of pregnant and postpartum women living in a group of slum communities in the city of Rio de Janeiro, RJ, Brazil.

The environmental pollution by human activity has been one of the most concerns in the last years, principally due to rapid urban growth in the cities and the industrialization process. The air pollution can be increased due to several different kinds of emissions: urban traffic, industrial activities, burning fuel, civil industry of construction/demolition, fires and natural phenomena. Many of these emissions move from long distances due to convections currents and finally tend to deposit mainly in the plants leaves and in the soil. Thus, the plants leaves works as a natural sampler by the emissions deposit in these ones. In this study Nerium oleander leaves were used to measure the environmental pollutions levels in different sampling urban regions in the city of Rio de Janeiro/RJ: Andarai, Benfica, Bonsucesso, Caju, Engenho de Dentro, Engenho Novo, Estacio, Grajau, Inhauma, Lins, Maracana, Maria da Graca, Meier, Praca da Bandeira, Riachuelo, Rio Comprido, Sao Cristovao, Tijuca, Vila Isabel and city Center. The control samples were collected in Campo Grande near of Parque Nacional da Pedra Branca/RJ (National Park of Pedra Branca/RJ). The leaves were collected from adult plants and after the collection the samples were cleaned and placed in the greenhouse for drying, then were mashed and pressed into tablets forms. The analyses were performed using the energy dispersion X-ray fluorescence (EDXRF), developed on the own laboratory and based in a SiPIN detector and a mini X ray tube. It was possible to detect 16 elements in the analyzed samples: K, Ca, Cr, Mn, Fe, Cu, Zn, Br, Rb, Sr, Ba and Pb. The results shows that, in the studied areas, the analysis of the Nerium oleander plant shows a low-cost option and with a substantial efficiency as an environmental pollution biomonitor. (author)

The environmental pollution by human activity has been one of the most concerns in the last years, principally due to rapid urban growth in the cities and the industrialization process. The air pollution can be increased due to several different kinds of emissions: urban traffic, industrial activities, burning fuel, civil industry of construction/demolition, fires and natural phenomena. Many of these emissions move from long distances due to convections currents and finally tend to deposit mainly in the plants leaves and in the soil. Thus, the plants leaves works as a natural sampler by the emissions deposit in these ones. In this study Nerium oleander leaves were used to measure the environmental pollutions levels in different sampling urban regions in the city of Rio de Janeiro/RJ: Andarai, Benfica, Bonsucesso, Caju, Engenho de Dentro, Engenho Novo, Estacio, Grajau, Inhauma, Lins, Maracana, Maria da Graca, Meier, Praca da Bandeira, Riachuelo, Rio Comprido, Sao Cristovao, Tijuca, Vila Isabel and city Center. The control samples were collected in Campo Grande near of Parque Nacional da Pedra Branca/RJ (National Park of Pedra Branca/RJ). The leaves were collected from adult plants and after the collection the samples were cleaned and placed in the greenhouse for drying, then were mashed and pressed into tablets forms. The analyses were performed using the energy dispersion X-ray fluorescence (EDXRF), developed on the own laboratory and based in a SiPIN detector and a mini X ray tube. It was possible to detect 16 elements in the analyzed samples: K, Ca, Cr, Mn, Fe, Cu, Zn, Br, Rb, Sr, Ba and Pb. The results shows that, in the studied areas, the analysis of the Nerium oleander plant shows a low-cost option and with a substantial efficiency as an environmental pollution biomonitor. (author)

The interactions between aerosols and ice clouds (consisting only of ice) represent one of the largest uncertainties in global radiative forcing from pre-industrial time to the present. The observational evidence for the aerosol impact on ice cloud properties has been quite limited and showed conflicting results, partly because previous observational studies did not consider the distinct features of different ice cloud and aerosol types. Using 9-year satellite observations, we find that, for ice clouds generated from deep convection, cloud thickness, cloud optical thickness (COT), and ice cloud fraction increase and decrease with small-to-moderate and high aerosol loadings, respectively. For in-situ formed ice clouds, however, the preceding cloud properties increase monotonically and more sharply with aerosol loadings. The case is more complicated for ice crystal effective radius (Rei). For both convection-generated and in-situ ice clouds, the responses of Rei to aerosol loadings are modulated by water vapor amount in conjunction with several other meteorological parameters, but the sensitivities of Rei to aerosols under the same water vapor amount differ remarkably between the two ice cloud types. As a result, overall Rei slightly increases with aerosol loading for convection-generated ice clouds, but decreases for in-situ ice clouds. When aerosols are decomposed into different types, an increase in the loading of smoke aerosols generally leads to a decrease in COT of convection-generated ice clouds, while the reverse is true for dust and anthropogenic pollution. In contrast, an increase in the loading of any aerosol type can significantly enhance COT of in-situ ice clouds. The modulation of the aerosol impacts by cloud/aerosol types is demonstrated and reproduced by simulations using the Weather Research and Forecasting (WRF) model. Adequate and accurate representations of the impact of different cloud/aerosol types in climate models are crucial for reducing the

E-mail: monicafloriao@hotmail.com Coccidiosis or bovine eimeriosis is an intestinal disease caused by species of the genus Eimeria Schneider, 1875. It is responsible for gastrointestinal disorders and in some cases, animals died, especially the young animals. The proposed organic management for the system was relevant in establishing the health of the studied herd. Only some of the animals had clinical signs of acute eimeriosis. In nursing calves clinical signs appeared at 30 days old, during the first period of the study (2013-2014, occurring shortly after abrupt change in management, when the amount of milk supplied to animals of this extract was reduced. The other two cases occurred during the second period of the study (2014-2015, after fire in the area of pastures, causing the batch of weaned calves come into pasture destined to cows, with such abrupt change in management developed clinical signs of acute eimeriosis. The most frequent species was E. zuernii in both extracts, followed by E. cylindrica in nursing calves, and E. bovis and E. bukidnonensis in the weaned calves. The recovery of the animals was performed with the return to the proposed organic management associated with use of homeopathic medication. In addition, the animals recovered their body weight gains established for Gir breed (zebu dairy cattle and its cross breeds.

Epigenetic modification of gene expression in honey bees by heterospecific gland secretions.

Yuan Yuan Shi

Full Text Available In the honey bee (Apis mellifera, queen and workers have different behavior and reproductive capacity despite possessing the same genome. The primary substance that leads to this differentiation is royal jelly (RJ, which contains a range of proteins, amino acids, vitamins and nucleic acids. MicroRNA (miRNA has been found to play an important role in regulating the expression of protein-coding genes and cell biology. In this study, we characterized the miRNAs in RJ from two honey bee sister species and determined their possible effect on transcriptome in one species.We sequenced the miRNAs in RJ either from A. mellifera (RJM or A. cerana (RJC. We then determined the global transcriptomes of adult A. mellifera developed from larvae fed either with RJM (mRJM or RJC (mRJC. Finally we analyzed the target genes of those miRNA that are species specific or differentially expressed in the two honey bee species. We show that there were differences in miRNA between RJM and RJC, and that transcriptomes of adult A. mellifera were affected by the two types of RJ. A high proportion (23.3% of the affected genes were target genes of differential miRNAs.We show for the first time that there are differences in miRNAs in RJ between A. mellifera and A. cerana. Further, the differences in transcriptomes of bees reared from these two RJs might be related to miRNA differences of the two species. This study provides the first evidence that heterospecific royal jelly can modify gene expression in honey bees through an epigenetic mechanism.

Full Text Available The present work was designed to assess the radioprotective effect of royal jelly (RJ against radiation-induced apoptosis in human peripheral blood leukocytes. In this study, peripheral blood samples were obtained on days 0, 4, 7, and 14 of the study from six healthy male volunteers taking a 1000 mg RJ capsule orally per day for 14 consecutive days. On each sampling day, all collected whole blood samples were divided into control and irradiated groups which were then exposed to the selected dose of 4 Gy X-ray. Percentage of apoptotic cells (Ap % was evaluated for all samples immediately after irradiation (Ap0 and also after a 24 h postirradiation incubation at 37°C in 5% CO2 (Ap24 by the use of neutral comet assay. Concerning Ap0, collected data demonstrated that the percentage of apoptotic cells in both control and irradiated groups did not significantly change during the study period. However, with respect to Ap24, the percentage of apoptotic cells in irradiated groups gradually reduced during the experiment, according to which a significant decrease was found after 14 days RJ consumption (P = 0.002. In conclusion, the present study revealed the protective role of 14 days RJ consumption against radiation-induced apoptosis in human peripheral blood leukocytes.

Wedding, Jason L.; Harris, Hugh H.; Bader, Christie A.; Plush, Sally E.; Mak, Rachel

2016-01-01

Optical fluorescence microscopy was used in conjunction with X-ray fluorescence microscopy to monitor the stability and intracellular distribution of the luminescent rhenium(I) complex fac-[Re(CO) 3 (phen)L], where phen = 1,10-phenathroline and L = 5-(4-iodophenyl)tetrazolato, in 22Rv1 cells. The rhenium complex showed no signs of ancillary ligand dissociation, a conclusion based on data obtained via X-ray fluorescence imaging aligning iodine and rhenium distributions. A diffuse reticular localisation was detected for the complex, in the nuclear/perinuclear region of cells, by either optical or X-ray fluorescence techniques. Furthermore, X-ray fluorescence also showed that the Re-I complex disrupted the homeostasis of some biologically relevant elements, such as chlorine, potassium and zinc.

Full Text Available Os estudos iniciais sobre a soroprevalência de anticorpos anti-VIH-1 (Ac-VIH em unidades de hemodiálise no Estado do Rio de Janeiro (RJ foram feitos em 1985. Os números alarmantes, próximos a 14%, foram atribuídos à má qualidade do sangue obtido de "doadores profissionais" em troca de comida ou dinheiro. Recentemente uma série de medidas foram adotadas na tentativa de reduzir o tráfico de sangue. Nossa investigação objetivou avaliar o impacto destas na soroprevalência de Ac-VIH em duas unidades satélites no RJ. A Clínica Segumed foi uma das unidades estudadas em 1985. Em 1987 realizamos um segundo levantamento no mesmo grupo estudado previamente. A Casa de Saúde Grajaú, inaugurada em 1986 com a maioria dos pacientes novos em diálise, foi estudada em 1988. O teste ELISA HIV-1 foi utilizado como rastreamento. Os resultados positivos foram confirmados com Western blot. Os resultados na Segumed mostraram uma grande diferença entre os dois levantamentos (14,4% vs 3,6%. Os dois casos positivos em 1987 estavam entre os identificados em 1985. Nenhum paciente se infectou entre os dois levantamentos apesar de não se utilizarem medidas de isolamento para os portadores de VIH e do uso de transfusões ter aumentado no período. Na CS Grajaú apenas dois casos foram encontrados (soroprevalência 2,4% embora um já fosse conhecido desde 1985 quando vivia com um transplante. Uma revisão de estudos semelhantes no RJ e São Paulo parece revelar uma tendência à diminuição das taxas nos últimos anos. Nós concluímos que a chance de contaminação com VIH é atualmente reduzida nos centros estudados e pode estar caindo globalmente no RJ. É possível que a maior vigilância, e até fechamento de bancos de sangue, tenha resultado na melhora da qualidade do sangue no RJ.The initial surveys on the seroprevalence of anti-HIV-1 antibodies (HIV-Ab in hemodialysis units in the State of Rio de Janeiro (RJ were done in 1985.

Full Text Available A morte de Bourdieu, que todos consideravam o maior sociólogo da língua francesa, deixou um grande vazio intelectual, difícil de ser preenchido. Neste artigo, em um primeiro momento, a autora situa, para fins analíticos, os processos pelos quais a transmissão de sua herança tem sido feita, na esfera institucional, e as posições intelectuais, de seus principais seguidores, nela presentes. As oportunidades de aspirar a esta herança parecem estar divididas entre três candidatos: Bernard Lahere, Jean-Claude Kaufmann e Gisèle Sapiro, autores que estão em diferentes etapas de suas carreiras e os únicos a oferecer uma crítica respeitosa da teoria de Bourdieu e a propor sua extensão. Os primeiros dois autores partem do conceito de habitus e a última de campo. Conclui comentando como o desdobramento do pensamento de Bourdieu sobre a educação pode contribuir para o debate acadêmico brasileiro nessa área.

Full Text Available The article analyzes four Brazilian documentaries inspired by the community studies method and structured on a collage of interviews as the final discourse. These narratives are problematic, even in terms of the interviews and the testimonies themselves. Far from being a dialogue set on stage, they reflect an attempt at transparency on the part of the filmmaker. In our opinion, this leads to serious ethical infractions, primarily because it reveals, without intermediation, the intimacy of those being interviewed. For example, it would free a couple taking advantage of the documentary, and its limited reception, of any inhibitions about expressing their disagreements.

Identification of Bradyrhizobium elkanii Genes Involved in Incompatibility with Vigna radiata

Directory of Open Access Journals (Sweden)

Hien P. Nguyen

2017-12-01

Full Text Available The establishment of a root nodule symbiosis between a leguminous plant and a rhizobium requires complex molecular interactions between the two partners. Compatible interactions lead to the formation of nitrogen-fixing nodules, however, some legumes exhibit incompatibility with specific rhizobial strains and restrict nodulation by the strains. Bradyrhizobium elkanii USDA61 is incompatible with mung bean (Vigna radiata cv. KPS1 and soybean cultivars carrying the Rj4 allele. Here, we explored genetic loci in USDA61 that determine incompatibility with V. radiata KPS1. We identified five novel B. elkanii genes that contribute to this incompatibility. Four of these genes also control incompatibility with soybean cultivars carrying the Rj4 allele, suggesting that a common mechanism underlies nodulation restriction in both legumes. The fifth gene encodes a hypothetical protein that contains a tts box in its promoter region. The tts box is conserved in genes encoding the type III secretion system (T3SS, which is known for its delivery of virulence effectors by pathogenic bacteria. These findings revealed both common and unique genes that are involved in the incompatibility of B. elkanii with mung bean and soybean. Of particular interest is the novel T3SS-related gene, which causes incompatibility specifically with mung bean cv. KPS1.

10-Hydroxy-2-Decenoic Acid in Royal Jelly Extract Induced Both Filaggrin and Amino Acid in a Cultured Human Three-Dimensional Epidermis Model

Full Text Available Royal jelly (RJ is a natural product which the honeybee secretes as a special diet for a queen bee. It is one of the natural products in which various functionalities, such as antibacterial effects, immunomodulating properties, and estrogen-like action, were reported. We investigated the effect of the RJ extract on the moisturizing effect by topical application in humans. The stratum corneum moisture was increased significantly after four weeks by using the RJ extract lotion compared to placebo lotion. RJ extract contained a characteristic ingredient, 10-hydroxy-2-decenoic acid (10H2DA and 10-hydroxydecanoic acid (10HDAA, etc. However, the mechanism of stratum corneum moisture and its contributing ingredient have not yet been elucidated. We have investigated the effects of 10H2DA and 10HDAA on the free amino acids content in the stratum corneum using a cultured human three-dimensional epidermis model. Additionally, the effect of 10H2DA and 10HDAA on the amounts of filaggrin (FLG and aquaporin 3 (AQP3 were investigated at the mRNA level and by immunohistochemistry using a cultured human epidermis model. It was determined that 10H2DA increases the free amino acids in the stratum corneum of the cultured human epidermis model, and that it increased FLG on both the mRNA and protein levels. On the other hand, these actions are not observed by treatment of 10HDAA. The mRNA and protein level of AQP3 did not increase with 10H2DA or 10HDAA use. It was thought that the increase in the amount of FLG and the increase in the free amino acids of the epidermis and the stratum corneum, respectively, by 10H2DA were participating in the moisturizing function of the stratum corneum by the continuous use of RJ extract lotion.

This study is aimed to evaluate the possible neurotoxic effect of tartrazine (T), an extensively used synthetic azo dye, as well as to determine the potential modulatory role of cod liver oil (CLO) or royal jelly (RJ) against such effects. For this purpose, thirty-six male rat pups were allocated into six groups. The 1st group received distilled water (control group), the 2nd group was given 300 mg RJ/kg bw (RJ group), the 3rd group was given 0.4 ml CLO/kg bw (CLO group), the 4th was given 500 mg T/kg bw (T group). The 5th group was given T concurrently with RJ (TRJ group) and the 6th group was given T concurrently with CLO (TCLO group), at the same doses as the former groups. All treatments were given orally for 30 consecutive days. The concentrations of different brain neurotransmitters, gamma amino butyric acid (GABA), dopamine (DA) and serotonin (5HT) as well as the antioxidant and oxidative stress biomarkers were measured in the brain homogenates. An immunohistochemical staining of the cerebral cortex was applied with the anti-ssDNA antibody (an apoptotic cell marker) to reveal the changes in brain structure. The T group revealed a significant decrease in the concentration of the brain neurotransmitters, a sharp shortage in the level of antioxidant biomarkers (super oxide dismutase, catalase and the reduced glutathione), a marked increase in malondialdehyde levels, and numerous apoptotic cells in the brain cortex compared with the other groups. Interestingly, all the previously mentioned parameters were almost retrieved in both the TRJ and TCLO groups compared to the T group. These results conclusively demonstrate that RJ and CLO administration provides sufficient protection against the ruinous effects of T on rat pups brain tissue function and structure.

Exergo-economic analysis of finned tube for waste heat recovery including phase change heat transfer

International Nuclear Information System (INIS)

Wu, Shuang Ying; Jiu, Jing Rui; Xiao, Lan; Li, You Rong; Liu, Chao; Xu, Jin Liang

2013-01-01

In this paper, an exergo-economic criterion, i.e. the net profit per unit transferred heat load, is established from the perspective of exergy recovery to evaluate the performance of finned tube used in waste heat recovery. Also, the dimensionless exergy change number is introduced to investigate the effect of the flow (mechanical) exergy loss rate on the recovered thermal exergy. Selecting R245fa as a working fluid and exhaust flue gas as a heat source, the effects of the internal Reynolds number Re_i, the external Reynolds number Re_o , the unit cost of thermal exergy ε_q , the geometric parameter of finned tube η_oβ and the phase change temperature T_v etc. on the performance of finned tube are discussed in detail. The results show that the higher T_v and η_oβ, and lower Re_i may lead to the negligible flow(mechanical) exergy loss rate. There exists an optimal value of Re_i where the net profit per unit transferred heat load peaks, while the variations of Re_o, ε_q and T_v cause monotonic change of the net profit per unit transferred heat load. The phase change temperature exerts relatively greater influence on the exergo-economic performance of finned tube in comparison with other parameters. And there exists a critical phase change temperature, where the net profit per unit transferred heat load is equal to zero.

Full Text Available Bogs are ecosystems found mainly in lower zones that separates inner and outer sandy terraces, and rivers and streams from valleys. These environments are always flooded or suffer seasonal flooding or can stay dry in a extended dry season. Its shallow waters increase the role of the sediment in the maintenance of such ecosystem. The Brejo do Espinho (22º56’ S and 42º14’W is a coastal body of water located 108 km from Rio de Janeiro city where are observed the development of thick microbial mats (about 2-4 cm in thickness. Aiming the characterization of the microbial mats, was made monthly collections in five collects in stations located in the bog borders. Microbial mats samples were taken using a spatula, deposited into plastics vials and later fixed with 4% formaldeid solution. For identification of the cyanobacterias, fresh and permanent slides were made. Smooth layered microbial mats present in subtidal and intertida regions are composed by thin layers with different colors: green, red and brown, who show also distinct cyanobacterialcomposition. These structures show stratus of cohesive lamina with low lithification. Analysis revealed 27 species of cyanobacterias. Chroococcaceae Nägeli 1849 family was the main family found with 37% of the total frequency followed by Phormidiaceae Anagnostidis & Komárek 1988 family with 18,5%, Synechococcaceae Komárek & Anagnostidis 1995 family with 11,1%, Pseudanabaenaceae Anagnostidis & Komárek 1988 family with 11,1%, Entophysalidaceae Geitler1925 family with 7,4%, Schizothricaceae Elenkin 1934 family with 7,4% and Oscillatoriaceae Gomont 1892 family with 7,4%. The domain of cyanobacterias in the Brejo do Espinho reflects its general plasticity that allows them to adapt to hostile conditions of the environment.

Full Text Available Large extensions of the coastal sandy soils (restinga vegetation of the northern region of Rio de Janeiro had been eliminated since the colonization, with replacement of the native vegetation by sugarcane cultivation followed by agricultural expansion. The Açu Lagoon State Park (PELAG was created with the goal of preserve part of the remaining ecosystem, sandbanks, swamps, marshes and coastal lagoons, reminiscent of ecosystems that existed in the region before its degradation. In order to have a better characterization of the area delimited for its implantation, the present work has the objective of mapping the land use in the Park. The classification was performed through supervised classification with visual interpretation pixel by pixel and applying the maximum likelihood, where the following categories were considered: water, wet soils, vegetation, exposed soils and pastures. The results obtained were consistent with the reality observed in the field. It was observed that the highest percentage of soil cover is composed of pasture (27.8%, followed by wetlands (25.74% and wet soil (22.22%. Approximately 16.0% of the area of the park is covered by vegetation, characterized mainly by coastal sandy soils (restinga. A large part of the park area is devoid of vegetation cover, and it is necessary to recompose it, mainly that from the permanent preservation areas.

Royal jelly (RJ) produced by honeybees has been reported to possess diverse health-beneficial properties and has been implicated to have a function in longevity across diverse species as well as honeybees. 10-Hydroxy-2-decenoic acid (10-HDA), the major lipid component of RJ produced by honeybees, was previously shown to increase the lifespan of Caenorhabditis elegans. The objective of this study is to elucidate signaling pathways that are involved in the lifespan extension by 10-HDA. 10-HDA f...

Full Text Available A experiência de Ouvidoria Coletiva desenvolvida na região da Leopoldina, na cidade do Rio de Janeiro, amplia a visão tradicional de vigilância em saúde e objetiva organizar um sistema de vigilância capaz de identificar os problemas de saúde da população e os recursos utilizados na tentativa de superá-los. Profissionais de saúde, líderes comunitários e religiosos se reuniram em fóruns mensais para apresentar e discutir as condições de vida percebidas nas comunidades em que atuam. A partir do olhar das dimensões sociais envolvidas nos processos de saúde-doença, este trabalho visa discutir de que forma a pobreza compromete a saúde das classes populares, especialmente no que se refere à saúde mental e ao "sofrimento difuso". A metodologia permitiu organizar, de modo sistemático, a escuta e favoreceu o reconhecimento do saber local, construído a partir das experiências de vida das pessoas que lidam com o sofrimento, a doença e seus determinantes nas condições de vida da população. A situação de pobreza absoluta de uma parcela significativa da população foi percebida como geradora de impasses para a resolução de problemas de saúde. Os resultados confirmam a importância de se compreenderem as estratégias de enfrentamento da população e as propostas para possíveis ações no campo da saúdeThe experience of Collective Ombudsman developed in the Leopoldina region, city of Rio de Janeiro, enlarges the traditional vision of health vigilance and consists in organizing a system of qualitative evaluation of the sanitary vigilance able to identify the health problems of the population and the methods utilized in the attempt to overcome these problems. Health professionals, religious and community leaders congregated in monthly forums to present and discuss living conditions perceived in the communities in which they carry on their activities.

Full Text Available ABSTRAK Penelitian ini mengunkap tentang persepsi masyarakat terhadap Penerapan Upaya Pengelolaan Lingkungan dan Upaya Pemantauan Lingkungan di Sub-Distrito Cristo Rei, Distrito Dili. Tujuan penelitian ini untuk mengetahui faktor yang mempengaruhi persepsi masyarakat terhadap penerapan Upaya Pengelolaan Lingkungan dan Upaya Pemantauan Lingkungan di Sub-Distrito Cristo Rei, Distrito Dili dan persepsi terhadap dampak lingkungan yang akan timbul akibat oleh kegiatan bidang pariwisata. Pengumpulan data penelitian menggunakan metode survai dengan menggunakan kuesioner sebagai alat penelitian.  Jumlah Kepala Keluarga (KK yang tinggal di Desa (Suco Meti Aut, Sub-Distrito Cristo Rei yaitu sebanyak 376 (KK dari total jumlah penduduk sebayak 1.501 jiwa. Dari jumlah tersebut diambil 88 KK sebagai sampel responden dengan menggunakan teknik acak sederhana (simple random sampling. Cara penilaian dilakukan dengan memberikan skor pada tiap pertanyaan di kuesioner, kemudian dianalisis menggunakan uji Chi Square serta korelasi stastistik. Hasil penelitian menunjukkan bahwa faktor sosial ekonomi (tingkat pendidikan, jenis pekerjaan dan tingkat pendapatan memiliki pengaruh yang kuat terhadap persepsi masyarakat tentang penerapan Upaya Pengelolaan Lingkungan dan Upaya Pemantauan Lingkungan pada pembangunan bidang pariwisata. Semakin baik tingkat pengetahuan responden, maka semakin baik pengaruhnya terhadap persepsi penerapan UKL-UPL pada pembagunan bidang pariwisata. Sementara jumlah anggota keluarga tidak memiliki pengaruh yang kuat terhadap persepsi penerapan UKL-UPL. Semakin banyak jumlah tanggungan keluarga, persepsi terhadap penerapan Upaya Pengelolaan Lingkungan dan Upaya Pemantauan Lingkungan semakin buruk. Hal yang sama juga didapatkan untuk persepsi dampak lingkungan. Pemahaman dan kesadaran akan pentingnya lingkungan hidup sebagian masyarakat masih lemah hal ini sangat mengharapkan pemerintah untuk meningkatkan sosialisasi peraturan dan kebijakan

This paper presents simple and relatively efficient methods to estimate some physical and chemical properties of polycyclic alkanes. These properties are melting point, normal boiling point, standard enthalpy of vaporization at 298 K, standard enthalpy of formation at 298 K, standard enthalpy of combustion at 298 K, density (specific gravity) and flash point. These methods are validated, despite the scarcity of experimental data, with several tens of polycyclic alkanes. Then the methods are used to estimate properties of some polycyclic alkanes, which are currently in use as missile fuels: JP-10, RJ-4 and RJ-5. Estimates and experimental data are found in good agreement for these fuels. This methodology is then used to evaluate missile fuel candidates to be used pure or as additive to JP-10 or to blends such as RJ-6. Several compounds are probably of interest for this task and their advantages and drawbacks are discussed. (Abstract Copyright [2006], Wiley Periodicals, Inc.)

In this study, the proteins contained in royal jelly (RJ) produced by Africanized honeybees and European honeybees (Apis mellifera) haven been analyzed in detail and compared using two-dimensional gel electrophoresis, and the N-terminal amino acid sequence of each spot has been determined. Most spots were assigned to major royal jelly proteins (MRJPs). Remarkable differences were found in the heterogeneity of the MRJPs, in particular MRJP3, in terms of molecular weights and isoelectric points between the two species of RJ. Furthermore, during the determination of the N-terminal amino acid sequence of each spot, for the first time, MRJP4 protein has been identified, the existence of which had been only implied by cloning of its cDNA sequence. The presence of heterogeneous bands of glucose oxidase was also identified. Thus, the results suggest that two-dimensional gel electrophoresis provides a suitable method for the qualitative analysis of the proteins contained in RJ derived from different honeybee species.

Economic polarization is a process that is present at global, national and regional level. Economic activity is extremely spatially concentrated. Cities and developed regions use the agglomeration effect to attract labor and capital, thus achieving more favorable economic conditions than the agrarian region. Scientific research and European experiences over the past decades have contributed to the discrepancy among theorists about the causes and consequences of regional inequalities. Regional...

Fish resources management in Brazil and overview of artisanal fisheries in Macaé, RJ

Full Text Available The aim of this review is to highlight the sociocultural and environmental importance of artisanal fisheries for the city of Macaé, Rio de Janeiro, Brazil, providing information about the main artisanal fisheries methods applied by the fishers, a brief history of public policy for fishing in Brazil, and an overview of the economy working relations and fish marketing in that city. Once the definitions of artisanal and industrial fishing are modified according to the State or region, we are consider artisanal fishing, for the purpose of this work, as that practiced by professional fisherman directly, independently, or as family economy, with production means of their own, or through partnership contract, landed, allowing the use of small ships. Five main artisanal fishing methods were detected in Macaé: (i the line method, (ii the method of surface longline; (iii the driftnet method; (iv the drag; and (v the method of network seines, or pair. In this analysis, we focused on four major public policy processes which led to setting up a model of fishery management, in which crisis is evident, with an overcoming not yet fully delineated. Since the fishing activity is important for the region, the development of studies able to define the supply chain structuring programs, expansion of investments, creation of a framework for its own staff and, especially aimed at management concepts that can coordinate all activity from production, through processing to marketing, are significant steps to strengthen the fisheries policy in the city of Macaé.
