One of the ways to preserve the beans, and at the same time keep its nutritional characteristics, is the use of gamma radiation. This study aimed to evaluate the effects of different doses of gamma radiation on the physical and chemical properties of the carioca variety of common beans subject to cooking of soaked and unsoaked beans.

Portions of raw beans were used as control and the other was subject to ionizing radiation at doses of 1, 5 and 10 kGy. Following irradiation, a portion of the samples control and irradiated were soaked and the other was not, then all beans were cooked. The cooked samples were lyophilized, milled and then accommodated in pots and stored at deg C temperatures. The analysis of chemical composition, determination of protein digestibility, condensed tannin and phytic acid content were performed using the milled samples.

Using whole grains, were performed analysis of expansion capability and hydration, cooking time and instrumental color. Irradiation did not alter the chemical composition of soaked and unsoaked samples. The condensed tannin levels did not reduce according to increased doses. The phytic acid concentrations were reduced at the doses of 5 and 10 kGy for soaked samples, whereas for the not soaked beans, gamma irradiation did not influence the phytate content. The protein digestibility decreased on soaked samples, at doses of 1 kGy and in the other doses, the reduction was not significant.

As for not soaked beans, increases in digestibility were observed at dose of 10 kGy. As the doses increased, reduction in cooking time on soaked and unsoaked beans was noted. At a dose of 10 kGy, the bean expansion capability increased. The samples' color did not change significantly, as the doses increased.

Therefore, it is concluded that ionizing radiation has no effect on the chemical composition and tannin content. Irradiation influenced the phytates when applied in higher doses, but only in soaked samples, as well as mitigate protein digestibility on soaked beans. It reduces cooking time, raises bean expansion capability at a 10 kGy dose, but it does not change the bean color as doses increase.

Se describen dos circuitos de almacenamiento de respuesta lineal dentro de una amplia gama de amplitudes de las senales de salida. En uno de los circuitos la senal de error se mide con un amplificador diferencial. Gracias al elevado factor de amplificacion, el aparato funciona con caracteristicas sensiblemente lineales. El otro circuito esta disenado para trabajar con impulsos de una duracion del orden del nanosegundo.

Los impulsos de entrada de anchura normal cierran el circuito de un pentodo en cuyo anodo se halla el condensador que actua como ''memoria''. Como el condensador se carga desde el anodo por medio de un generador, la intensidad de corriente de carga permanece casi constante aunque la tension del condensador varie durante la medicion. El pentodo tiene una gran resistencia interna, de modo que al terminar el impulso de entrada, la corriente que atraviesa el pentodo tiene casi la misma intensidad que al principio, quedando asi almacenada la carga acumulada por el condensador.

Para prolongar la duracion de la ''memoria'' se puede colocar un diodo delante del condensador.

Las fuentes geotermicas no tradicionales incluyen las partes profundas y los limites de los reservorios hidrotermales tradicionales, los sistemas en roca seca o humeda caliente, los yacimientos geopresurizados del Golfo de Mexico y los sistemas submarinos hidrotermales observados principalmente en la costa norte mexicana del Oceano Pacifico. La energia geotermica submarina surge por la existencia de rupturas profundas en el fondo marino, a lo largo de los centros de dispersion oceanicos entre las placas tectonicas. Estos sistemas tienen una longitud total aproximada de 65, Km.

Hay dos tipos basicos de sistemas marinos existentes en el Golfo de California: El calor submarino poco profundo tambien se relaciona con fallas y fracturas en el fondo del mar cerca de algunas costas. El potencial preliminar de la energia contenida en tales reservorios se estima, en promedio, en MWt por cada km3 de roca submarina. Las caracteristicas quimicas especificas de las aguas hidrotermales encontradas en esos sistemas oceanicos indican que las interacciones agua-roca, ocurren bajo condiciones de presion y temperatura altas.

La energia geotermica submarina soporta ricas variedades de comunidades biologicas a profundidades donde las plantas no tienen acceso a la luz solar para realizar la fotosintesis. Hay indicios de que las posibles condiciones para la sintesis de sustancias y elementos quimicos necesaria para el origen de la vida primitiva, pudieron ser los sistemas hidrotermales submarinos.

Los generadores de calentamiento por induccion son puentes inversores con carga resonante, cuya mision es basicamente crear una corriente sinusoidal de gran amplitud sobre la "bobina de caldeo", que forma parte del tanque resonante. En el interior de esta bobina se introduce la pieza que se desea calentar. EI campo magnetico creado induce corrientes superficiales corrientes de Foucault sobre la pieza, que producen su calentamiento. Los tanques resonantes tambien llamados osciladores utilizados en la actualidad son el resonante serie y el resonante paralelo.

Aunque ya desde hace algun tiempo se vienen construyendo generadores de alta potencia basados en estos dos osciladores, el exito nunca ha. Tal y como se explica en la introduccion de esta memoria, los puentes inversores utilizados deben operar sobre una carga inductiva corriente retrasada para evitar el fenomeno de la recuperacion inversa de sus diodos y la consiguiente ruptura de los transistores. De la restriccion topologica anterior se deduce que el generador paralelo debe conmutar a frecuencias inferiores a la resonancia, y el serie a frecuencias superiores.

A esta restriccion topologica hay que unir otra que es exclusiva del calentamiento por induccion: La corriente por la bobina de caldeo debe ser sinusoidal. De no ser asi, resultaria imposible disponer toda la potencia de calentamiento sobre la pieza en el espesor requerido por la aplicacion.

La conjuncion de las dos restricciones anteriores obligan al inversor paralelo a funcionar a la frecuencia de resonancia del oscilador. Esto imposibilita un control por variacion de frecuencia, regulandose la potencia desde la. Full Text Available S. O ecologismo dos pobres. O Jardim dos Sonhos.

Influence of coprecipitation and mechanical mixture methods on the characteristics of nickel oxide-alumina composites; Influencia dos metodos de coprecipitacao e mistura mecanica nas caracteristicas de compositos oxido de niquel-alumina. Centro de Ciencia e Tecnologia de Materiais. Alumina-supported nickel catalysts are currently used in the reforming process due to low cost and high activity for hydrogen production from alcohols. In this work, the effect of preparation methods on nickel oxide-alumina based materials has been investigated.

Ceramic powders were obtained by coprecipitation in ammonia medium and mechanical mixture. Coprecipitated materials were calcined in air at deg C to obtain the corresponding oxides. Materials obtained by mechanical mixture were prepared by wet milling of nickel oxide and alumina powders, both synthesized by precipitation and calcination in air at and deg C, respectively.

Powders were characterized by X-ray diffraction, nitrogen gas sorption by applying the BET method, laser diffraction, scanning electron microscopy, electrophoretic mobility measurements for zeta potential determination and infrared spectroscopy. Methodology for determination of the operational limits in a atmospheric oven as a function of the load characteristics; Metodologia para determinacao dos limites operacionais de um forno atmosferico em funcao das caracteristicas da carga. The necessity of increasing the crude processing with operation periods even greater, are resulting in Atmospheric Distillation Units in severe conditions, requiring even more rigorous operational procedures.

The crude fired heaters are the critical equipment in this context, because they are the most susceptible to failures, if some determined limits are exceeded. During this analysis, it was verified that the operational limit of a fired heater cannot be determined only by its design thermal duty, it must be also taken into account the influence of the crude composition. This will determine, due to its film coefficient, the region of the radiation zone of the fired heater where it will begin the crude vaporization and will occur the greater temperatures.

The work conclusions resulted on the revision of the Unit operational procedures and definition of new crude processing limits. The fired heater operates with no problems since then. DOS cones along atomic chains. Variations of the local density of states DOS along the chain are investigated. They are crucial in scanning tunnelling experiments and give important insight into the electron transport mechanism and charge distribution inside chains.

It is found that depending on the chain parity the local DOS at the Fermi level can form cone-like structures DOS cones along the chain. The general condition for the local DOS oscillations is obtained and the linear behaviour of the local density function is confirmed analytically. DOS cones are characterized by a linear decay towards the chain which is in contrast to the propagation properties of charge density waves, end states and Friedel oscillations in one-dimensional systems.

We find that DOS cones can appear due to non-resonant electron transport, the spin-orbit scattering or for chains fabricated on a substrate with localized electrons. It is also shown that for imperfect chains e. We find that DOS cones can appear due to non-resonant electron transport, the spin—orbit scattering or for chains fabricated on a substrate with localized electrons. Dos chalets, en Suecia.

Mineralogical and micro-thermometric features of the Los Humeros geothermal reservoir, Pue.

Studies on many topics have been undertaken during the exploratory and exploitation stages of the development of Los Humeros geothermal field. Unlike what usually occurs in lizards, where the body length strongly predicts egg production, in C. Observed differences revealed variation in the weight-size of the egg within an individual clutch.

Therefore, there is not an optimization of the egg in the studied population of Ctenosaura , as usually occurs in small lizards. This variation associated with reproduction takes place in the middle of the dry season, and may be interpreted as an adaptation to facilitate the adjustment of different phenotypes in environments with extreme drought. La masa relativa de la nidada estuvo relacionada positivamente con el peso promedio de los huevos pero no con el volumen promedio del huevo.

Analysis preliminary phytochemical raw extract of leaves Nephrolepis pectinata. Full Text Available The Nephrolepis pectinata popularly known as paulista fern, ladder-heaven, cat tail, belongs to the family Davalliaceae. For the beauty of the arrangements of their leaves ferns are quite commercialized in Brazil, however, have not been described in the literature studies on their pharmacological potential.

Thus, the objective of this research was to analyze the phytochemical properties of the crude extract of the leaves of Nephrolepis pectinata.

Throughout one year, a total of 10 line transects were situated and recorded in the study area to determine relative abundance and density, and habitat type use dry forest, Nanchal, grassland, riparian veget We investigated the relationships between predator avoidance behavior and predation risk by comparing the wariness of iguanas Ctenosaura hemilopha belonging to an island population with few predators with that of iguanas belonging to a mainland population under high predation pressure. We predicted that island iguanas would be less wary than mainland ones.

Island iguanas allowed the closer approach of potential predators before their first reaction and fleeing. The responses of both sexes d Full Text Available Prairie cordgrass Spartina pectinata , a perennial C4 grass native to the North American prairie, has several distinctive characteristics that potentially make it a model crop for production in stressful environments. However, little is known about the transcriptome dynamics of prairie cordgrass despite its unique freezing stress tolerance. We used a RNA-sequencing method to assemble the S.

Six differentially expressed gene DEG groups were categorized from the profiling. In addition, two major consecutive orders of gene expression were observed in response to freezing; the first being the acute up-regulation of genes involved in plasma membrane modification, calcium-mediated signaling, proteasome-related proteins, and transcription regulators e.

The follow-up and second response was of genes involved in encoding the putative anti-freezing protein and the previously known DNA and cell-damage-repair proteins. Moreover, we identified the genes involved in epigenetic regulation and circadian-clock expression. Our results indicate that freezing response in S. Parasitism by a Digenea in Lucina pectinata Mollusca: Full Text Available Abstract Lucina pectinata is an important economic resource in the Brazilian coast. This study reports parasitism caused by a Digenea in this species.

The tissues were examined using an optical microscope. The mean length of L. Microscopic analysis showed sporocysts containing both germ balls as cercariae of an unidentified Digenea Platyhelminthes, these in various stages of development. The prevalence was 1. In a parasitized specimen was macroscopic evidence of tissue densification of gills. There were no other parasites found, which is probably related to inaccessibility and chemical conditions in which lives L.

There was a significant increase in monthly L. Never judge an iguana by its spines: Systematics of the Yucatan spiny tailed iguana, Ctenosaura defensor Cope, Spiny tailed iguanas are highly diverse clade of lizards in Mesoamerica, ranging from northern Mexico through Panama.

Utilizing 2 regions of mitochondrial DNA bp and 4 nuclear loci bp we explored the relationships between these species and the phylogeographic history of the major clades. We discovered that the lineage endemic to the Yucatan Peninsula renders the genus Ctenosaura paraphyletic. To resolve this non-monophyly, we resurrect the taxon Cachryx Cope, , and provide a new diagnosis for the genus. We also find that small body-size and highly spinose tails in the species previously referred to the subgenus Enyaliosaurus, have evolved independently 3 times.

Cachryx were recovered as sister to the lineage of iguanines endemic to the Galapagos Islands, and we discuss biogeographic scenarios to explain this relationship as well as those among the primary clades of Ctenosaura in Mesoamerica. Identification of a novel splicing form of amelogenin gene in a reptile, Ctenosaura similis. Full Text Available Amelogenin, the major enamel matrix protein in tooth development, has been demonstrated to play a significant role in tooth enamel formation. Previous studies have identified the alternative splicing of amelogenin in many mammalian vertebrates as one mechanism for amelogenin heterogeneous expression in teeth.

While amelogenin and its splicing forms in mammalian vertebrates have been cloned and sequenced, the amelogenin gene, especially its splicing forms in non-mammalian species, remains largely unknown. To better understand the mechanism underlying amelogenin evolution, we previously cloned and characterized an amelogenin gene sequence from a squamate, the green iguana. In this study, we employed RT-PCR to amplify the amelogenin gene from the black spiny-tailed iguana Ctenosaura similis teeth, and discovered a novel splicing form of the amelogenin gene.

The transcript of the newly identified iguana amelogenin gene named C. Similis-T2L is nucleotides long encoding an expected polypeptide of amino acids. Similis-T2L contains a unique exon denominated exon X, which is located between exon 5 and exon 6. Similis-T2L contains 7 exons including exon 1, 2, 3, 5, X, 6, and 7. Analysis of the secondary and tertiary structures of T2L amelogenin protein demonstrated that exon X has a dramatic effect on the amelogenin structures.

This is the first report to provide definitive evidence for the amelogenin alternative splicing in non-mammalian vertebrates, revealing a unique exon X and the splicing form of the amelogenin gene transcript in Ctenosaura similis. Throughout one year, a total of 10 line transects were situated and recorded in the study area to determine relative abundance and density, and habitat type use dry forest, Nanchal, grassland, riparian vegetation, and mangrove by the species.

This study reports a new C. Although this species has a very restricted distribution and is in danger of extinction, C. A total of individuals were recorded throughout the study. Results between seasons were similar. The Oaxacan Spiny tailed Iguana preferred first the dry forest, and then Nanchal, while avoided grassland, riparian vegetation, and mangroves. There was no difference in habitat use between males and females.

Mean perch heights were 1. Species observed as refuge and perch were B. Live trees hollows and branches were used by species. Main threats to the species are excessive hunting and habitat loss. Furthermore, grassland fires are still common in the study area.

One alternative approach to increase the content of bioactive compounds is fermentation. Poit is a plant that can be found in tropical area and potentially as anticancer, anti-inflammatory, insect repellant, antiviral and antioxidant.

In this research, efforts have been made to increase bioactive plant capacity of Hyptis pectinata L. Poit through submerged fermentation using Aspergillus niger. The study was performed by adding methanol extract of Hyptis pectinata L. Poit on two conditions, that was added at the beginning of fermentation and while entering a phase of death. Aspergillus niger growth rate in both conditions was observed by determining the dry weight of cells every 24 hours.

The transformation profil of extract was observed after 24 hours of extract addition in early death phase by the TLC method. The results show that the addition of Hyptis pectinata L. Poit extract at log phase triggers the cells to growth faster, whereas the addition at the early death phase precisely accelerates cell death. TLC profile shows the emergence of new compounds suspected as the products of transformation of Hyptis pectinata L.

Poit extract on day 8 after addition of extract. Aegiphila integrifolia, Cantinoa carpinifolia, C. Acetaminophen and zinc phosphide for lethal management of invasive lizards Ctenosaura similis. Full Text Available Reducing populations of invasive lizards through trapping and shooting is feasible in many cases but effective integrated management relies on a variety of tools, including toxicants. In Florida, using wild-caught non-native black spiny-tailed iguanas Ctenosaura similis, we screened acetaminophen and zinc phosphide to determine their suitability for effective population management of this prolific invasive species.

Of the animals that received acetaminophen, none died except at the highest test dose, mg per lizard, which is not practical for field use. We conclude that zinc phosphide has potential as a useful tool for reducing populations of invasive lizards such as the black spiny-tailed iguana provided target-selective delivery methods are developed [Current Zoology 57 5: Chemical composition and antimicrobial activity of the essential oil of Hyptis pectinata l. Chemical analysis showed that there was a predominance of sesquiterpenes, of which b-caryophyllene Twenty-one compounds were identified, and calamusenone was isolated using preparative thin layer chromatography with a silica gel plate 60 PF The minimal inhibitory concentration MIC and minimal microbicidal concentration MMC were determined for various pathogenic microorganisms.

The native range of Ctenosaura similis extends from southern Mexico through Panama. From an initial introduction of 3 animals in , the species now numbers in the thousands on Gasparilla Island in southwest Florida. In response to complaints of property damage from residents and threats to native species, local officials and the US Department of Agriculture Wildlife Services began a removal program in Through , trappers removed ctenosaurs. We necropsied ctenosaurs to document aspects of their natural history. We found oviducal eggs in females from early Apr to early Jun, approximately 2 months later than C.

We trapped hatchlings from late Jul to early Oct coincident with the summer rainy season. Clutch size increased with female body size, with 62 being the largest clutch size recorded. In general, the biology of the invasive population on Gasparilla Island resembles native C. We suggest that shorter day length and colder temperatures create environmental conditions that are suboptimal for individual growth compared to those in the native range.

A 2-year microplot experiment with the tested grasses growing on metal-contaminated soil was carried out. Simulated soil contamination with Cu, Ni, and Zn was introduced in the following doses in mg kg The phytoremediation potential of grasses was evaluated using a tolerance index TI , bioaccumulation factor BF , bioconcentration factor BCF , and translocation factor TF. The suitability of both grasses for Zn phytoextraction depended on the age of the plants. Both grasses were not suitable for Cu and Ni phytoextraction.

The research showed that one-season studies were not valuable for fully assessing the phytoremediation potential of perennial plants. Population genetic structure and demographic history of Atrina pectinata based on mitochondrial DNA and microsatellite markers. Information on its population genetic structure is crucial for the conservation of A. Considering its long pelagic larval duration and iteroparity with high fecundity, the genetic structure for A. However, the unusual oceanography in the coasts of China and Korea suggests potential for restricted dispersal of pelagic larvae and geographical differentiation.

In addition, environmental changes associated with Pleistocene sea level fluctuations on the East China Sea continental shelf may also have strongly influenced historical population demography and genetic diversity of marine organisms. Here, partial sequences of the mitochondrial Cytochrome c oxidase subunit I COI gene and seven microsatellite loci were used to estimate population genetic structure and demographic history of seven samples from Northern China coast and one sample from North Korea coast.

Despite high levels of genetic diversity within samples, there was no genetic differentiation among samples from Northern China coast and low but significant genetic differentiation between some of the Chinese samples and the North Korean sample. A late Pleistocene population expansion, probably after the Last Glacial Maximum, was also demonstrated for A. No recent genetic bottleneck was detected in any of the eight samples.

We concluded that both historical recolonization through population range expansion and demographic expansion in the late Pleistocene and current gene flow through larval dispersal were responsible for the weak level of genetic structure detected in A. Alberto Carvalho; Alves, Pericles B.

In this study, we established the first comprehensive transcript dataset of A. Biological and ecological characteristics of Pterocuma pectinata Malacostraca, Cumacea in Sasyk Reservoir. In — Sasyk was separated from the sea by a dam, connected by a canal with the Danube and transformed into a reservoir.

The fauna of Sasyk underwent significant changes and continues to adapt to the new conditions. This process is of great theoretical and practical interest. Cumacea — a small order, numbering about species; is represented in the Black Sea-Azov basin by 23 species, 11 of them belong to the Caspian complex. Due to their high quantity indicators, they play a significant role in the diet of many species of fish.

Pterocuma pectinata Sowinski, is the most abundant species of cumacean not only in the Sasyk Reservoir, but also in many bodies of water in the region. However, the biology and ecology of this group of animals has been very inadequately studied. The material for these studies was provided by benthic samples collected from 41 stations in the Sasyk Reservoir in the vegetation period — In this study we also used the material collected by means of H.

Hungerford underwater light traps. In total 4, specimens of cumaceans were processed. This article shows the results of the studyof the post-embryonic development, fertility and size-mass characteristic of P. For both sexes for age stages have been distinguished and described for cumaceans: Between breeding cycles, females live through one more preparatory intermediate stage; the males die.

This article provides a detailed morphological and morphometric description of all the stages of the ontogeny of cumaceans. The ratio of number of cumaceans at different stages of ontogeny varies considerably with the seasons. In the summer sexual development of cumacean occurs earlier than in the less warm seasons. A directly proportional relationship was found between body length. For species at risk of extinction, any parasites they have would be expected to face a similar fate.

In such cases, time is running out for efforts to identify and study their parasitic fauna before they are gone. We surveyed the hemoparasite fauna of 50 black-chested, spiny-tailed iguanas Ctenosaura melanosterna , a critically-endangered species, on an island off the coast of Honduras. Blood samples from captured animals were tested for hemoparasites by thin blood smear and molecular analyses. Based on microscopy, two parasites were identified, a Plasmodium sp. Efforts to amplify the Hepatozoon parasite using PCR were not successful. Additional surveys and studies of this host-parasite system would be valuable, both to science and to the management of this endangered animal.

The clam Lucina pectinata lives in sulfide-rich muds and houses intracellular symbiotic bacteria that need to be supplied with hydrogen sulfide and oxygen.

This clam possesses three hemoglobins: We characterized the complete gene sequence and promoter regions for the oxygen reactive hemoglobins and the partial structure and promoters of the HbI gene from Lucina pectinata. The gene expression levels of the clam Hbs, from sulfide-rich and sulfide-poor environments showed a significant decrease of expression in the symbiont-containing tissue for those clams in a sulfide-poor environment, suggesting that the sulfide concentration may be involved in the regulation of these proteins.

Gene expression evaluation of the two HbI mRNA variants indicated that the longer variant is expressed at higher levels than the shorter variant in both environments.

The continuity of the reproductive cycle of the specimens found in both studied periods could demonstrate a possible continuous reproduction of the species and a size for exploitation above Allopatric divergence of Stuckenia filiformis Potamogetonaceae on the Qinghai-Tibet Plateau and its comparative phylogeography with S. In the aquatic genus Stuckenia, the wide geographic range of S.

Using nuclear ITS sequence and ten chloroplast sequences, we conducted comparative phylogeographical analyses to investigate their distribution regions and hybrid zones in China, and compare their phylogeographical patterns and demographical histories. These two species were allopatric in China. These two species formed hybrid zones on the northeastern edge of QTP.

Most of the genetic variance of S. The geographical isolations caused by the Nyenchen Tanglha Mountains and the Tanggula Mountains promoted intraspecific diversification of alpine plants on the QTP. This study revealed the lack of phylogeographic structure in S. The ecological niche modeling showed that the distribution ranges of these two herbaceous species did not contract too much during the glacial period.

Remarkable difference in paralytic shellfish poisoning toxin distribution in tissues of pen shell atrina pectinata exposed to toxic red tide bloom. Pen shell atrina pectinata is one of the commercially important bivalves in Western Pacific region. In the Philippines, it is marketed as a whole meat or processed by shellfish harvesters to separate the abductor muscle as an export commodity.

During blooms of toxic dinoflagellate pyrodinium bahamense var. Toxic blooms directly affect the shellfish industry which includes A. In this study, samples of A. Bioaccumulation and distribution of PSP toxins were determined in different tissues namely, abductor muscle, mantle, gills, gonads, siphon, stomach and intestine using High Performance Liquid Chromatography post column derivatization method with fluorescence detection. Likewise, green mussels Perna viridis being the sentinel species for PSP monitoring in the Philippines were also collected in the same area and served as control.

Interestingly, results showed that the abductor muscle accumulates minimal level of PSP toxins and is several folds lower than the Philippine and international regulatory limits in contrast with the results obtained from P. Mantle parts showed toxicity values exceeding local regulatory limit and near to go beyond the international regulatory limit. Conversely, the remaining parts showed high toxicity values surpassing both regulation limits. Standard mouse bioassay regulatory used in PSP monitoring in the Philippines was also performed and revealed that the abductor muscle had non-detectable level of toxins.

Also, toxicity values from different. Full Text Available The article addresses the dilemma black children deal with as they construct and expose their blackness.

Full Text Available Single nucleotide polymorphisms SNPs are one of the most abundant DNA variants found in plant genomes and are highly efficient when comparing genome and transcriptome sequences. SNP marker analysis can be used to analyze genetic diversity, create genetic maps, and utilize marker-assisted selection breeding in many crop species. In order to utilize these technologies, one must first identify and validate putative SNPs.

Fifty-nine SNPs were validated using a core collection of 38 natural populations and a phylogenetic tree was created with one main clade. Samples from the same population tended to cluster in the same location on the tree. Polymorphisms were identified within Twelve selected SNP markers were used to assess the fidelity of tetraploid crosses of prairie cordgrass and their resulting F2 population.

These markers were able to distinguish true crosses and selfs. This study provides insight into the genomic structure of prairie cordgrass, but further analysis must be done on other cytotypes to fully understand the structure of this species. This study validates putative SNPs and confirms the potential usefulness of SNP marker technology in future breeding programs of this species.

The active shield-volcano Sierra Negra is part of the Galapagos hotspot. Sierra Negra is the largest shield volcano of Isabela Island, hosting a 10 km diameter caldera. Ten historic eruptions have occurred and some involved a frequently visited east caldera rim fissure zone called Volcan Chico.

Product description

The last volcanic event occurred in October and lasted for about a week, covering approximately twenty percent of the eastern caldera floor. Sierra Negra volcano has experienced some significant changes in the chemical composition of its volcanic gas discharges after the eruption. This volcanic event produced an important SO2 degassing that depleted the magmatic content of this gas. Not significant changes in the MORB and plume-type helium contribution were observed after the eruption, with a In a visible and diffuse gas emission study was performed at the summit of Sierra Negra volcano, Galapagos, to evaluate degassing rate from this volcanic system.

Mistletoe lectin is not the only cytotoxic component in fermented preparations of Viscum album from white fir Abies pectinata.

Full Text Available Abstract Background Preparations of mistletoe Viscum album are the form of cancer treatment that is most frequently used in the complementary medicine. Previous work has shown that these preparations are able to exert cytotoxic effects on carcinoma cells, the extent of which might be influenced by the host tree species and by the content of mistletoe lectin.

Methods Using colorimetric assays, we have now compared the cytotoxic effects of Viscum album preparations VAPs obtained from mistletoe growing on oak Quercus robur and Q. Results Each of the VAPs inhibited cell growth, but the extent of this inhibition differed with the preparation and with the cell line. Higher concentrations of VAP-P were required to obtain a comparable effect.

Bladder carcinoma cells were in most cases more sensitive to VAPs treatment than breast carcinoma cells. As to be expected from the low content of mistletoe lectin, VAP-P led to relatively weak cytotoxic effects. Most remarkably, however, the lectin-poor VAP-A revealed a cytotoxic effect comparable to, or even stronger. The occurence of radioactive minerals such as apatite and pyrochlore, in the alkaline chimneys of Serra Negra and Salitre Minas Gerais, Brazil , is discussed.

Also mentioned are other minerals of interest associated with the alkaline magma such as columbite, fluorite, monazite, zircon, baddeleyite, etc, which in favourable conditions may occur in deposits of great economical value, and which may present high contents of rare earths, thorium and uranium.

The voices of the excluded groups from Literature use it as social way and function to complain and present the themes that reveal the prejudices, fights, yearnings and difficulties of those who are putted aside of the established orders.

Measurements of visible and diffuse gas emission were conducted in at the summit of Sierra Negra volcano, Galapagos, with the aim to better characterize degassing after the eruption. The diffuse-to-plume CO2 emission ratio was about 1. Mina Azufral fumaroles released gasses containing Cavalcante, Maria de Jesus B.

The case of the Nahuas from the Sierra Negra allows us to establish a set of similarities and differences between these three major categories and to distinguish the features that can potentially guide their study in other cultural contexts. In this article, I use bibliographical sources and testimonies to analyse the reception of Fanon by the Brazilian intellectual milieu, as well as his influence upon the formation of black identities. As I observe a lukewarm reception I argue it was due to three factors: First, the specificity of the Latin American left in the 's; second, a national and racial makeup totally opposed to racial conflicts; and third the small number of black professors and researchers at Brazilian universities who focus on the formation of black identity or the affirmation of racially oppressed subjects.

Ele costuma diferenciar a cor preta da cor negra. Eduardo Sued transforms the black pigment of his physical palette in color fields on his paintings. He usually distinguishes black from "darkblack". He says black goes to "dark black" as darkness and intensity take hold of it. For him, the black works only on its surface, while "darkblack" is deep. The Rio Santiago in the Cordillera Negra of Peru is severely contaminated by acid mine drainage in its headwaters. ABSTRACT The objective is to highlight the possibilities of participation in the construction of political debates about the instrumentalities that the Internet offers.

It was sought to understand how black women boost their participation through the website of downloading digital videos Youtube. With the technological advances and greater purchasing power of the people, the cybernetic sphere has increasingly become a space for exposure and formation of opinions, which are often not only on-line, and can lead to advances in the construction and deconstruction of Guidelines. Methodologically, we did bibliographic review, observation and follow-up, with registration, of two channels of black women. We have shown that the empowerment and discussion of political issues about black women on Youtube were initially based on themes related to black aesthetics.

Recordar para re contar: Two-step counterdiffusion protocol for the crystallization of haemoglobin II from Lucina pectinata in the pH range 4—9. The composition of the haem pocket at the distal site includes TyrB10 and GlnE7, which are very common in other haem proteins.

Obtaining crystals of oxyHbII at various pH values is required in order to elucidate the changes in the conformations of TyrB10 and GlnE7 and structural scenarios induced by changes in pH. Here, the growth of crystals of oxyHbII using the capillary counterdiffusion CCD technique at various pH values using a two-step protocol is reported. In the first step, a mini-screen was used to validate sodium formate as the best precipitating reagent for the growth of oxyHbII crystals. The second step, a pH screen typically used for optimization, was used to produce crystals in the pH range 4—9.

Very well faceted prismatic ruby-red crystals were obtained at all pH values. X-ray data sets were acquired using synchrotron radiation of wavelength 0. All of the crystals were isomorphous and belonged to space group P4 2 2 1 2.

Fifty birds per treatment were housed in captivity and weighed individually once every two weeks. At nine weeks they were infected with pathogenic oocysts of Eimeria tenella, E. Biosorption is one of those processes that use biomass mostly inanimate for elimination of various chemical substances e. Until now algae have been studied as bio-sorbents in most cases, but we can also take advantage of wood pulp or sawdust that is normal waste material resulting in large amounts from various productions.

Considering the fact that bio-sorbent can be taken as natural ion exchanger containing slightly acidic or basic functional groups 2,3,4 , it is necessary to suppose that part of functional groups is filled by various metals before starting the measurements. Substituting these bound metallic cations by protonization we can gain biomass in given condition and some important information about the content of cations bound to bio-sorbent through ion exchange. The material used for biosorption observation was sawdust of Pinus negra Arnold.

For measurements we used the part which passed through the 0. By dehydrating at the C for the time of 24 hours we gained the water part that was 5.

The purpose of this study was to identify the presence of rickettsia and hantavirus in wild rodents and arthropods in response to an outbreak of acute unidentified febrile illness among Indians in the Halataikwa Indian Reserve, northwest of the Mato Grosso state, in the Brazilian Amazon. Where previously surveillance data showed serologic evidence of rickettsia and hantavirus human infection.

The arthropods were collected from the healthy Indian population and by flagging vegetation in grassland or woodland along the peridomestic environment of the Indian reserve. Wild rodents were live-trapped in an area bordering the reserve limits, due the impossibility of capturing wild animals in the Indian reserve. The wild rodents were identified based on external and cranial morphology and karyotype. DNA was extracted from spleen or liver samples of rodents and from invertebrate tick and louse pools, and the molecular characterization of the rickettsia was through PCR and DNA sequencing of fragments of two rickettsial genes gltA and ompA.

The amplification of the complete S segment was performed. A total of wild rodents, louse, and 36 tick specimens were collected in Laguna Negra hantavirus was identified in Calomys callidus rodents and Rickettsia bellii, Rickettsia amblyommii were identified in Amblyomma cajennense ticks. Zoonotic diseases such as HCPS and spotted fever rickettsiosis are a public health threat and should be considered in outbreaks and acute febrile illnesses among Indian populations.

The presence of the genome of rickettsias and hantavirus in animals in this Indian reserve reinforces the need to include these infectious agents in outbreak investigations of febrile cases in Indian populations. Foram estudados sistemas de cultivo simples e consorciado de Eucalyptus saligna Smith e Acacia mearnsii De Wild. We analyze trends of wage inequality of the Brazilian female labor force, by race, during the s and s. Increasing returns to skills and increasing demand for skilled labor result in a divergence of wages growth between high and low skilled workers.

This increasing gap results in an increase of wage inequality by race. In order to interpret trends, we take into account race differences in marriage patterns, fertility, household arrangements, educational levels, labor market participation, skill levels, occupational location and earnings, distinguishing between period and cohort measures. We use Brazilian Household Sample Surveys data to examine the importance of within- and between-cohort changes for black and white women.

Earnings functions are estimated from the pooled time-series of these cross-section data, using OLS and quantile regressions. Summary This article addressed the news related to black communities, mainly regarding racial discrimination and racism in the "Cartagena" section, based chronologically on two years: The "Cartagena" section is the second largest in the newspaper El Universal, where the main problems of the city are collected.

Se identifican cinco instituciones gubernamentales de relevancia para las mujeres: Full Text Available Stromatolites are organo-sedimentary structures that represent some of the oldest records of the early biosphere on Earth.

Cyanobacteria are considered as a main component of the microbial mats that are supposed to produce stromatolite-like structures. Understanding the role of cyanobacteria and associated microorganisms on the mineralization processes is critical to better understand what can be preserved in the laminated structure of stromatolites. Laguna Negra Catamarca, Argentina, a high-altitude hypersaline lake where stromatolites are currently formed, is considered as an analog environment of early Earth. This study aimed at characterizing carbonate precipitation within microbial mats and associated oncoids in Laguna Negra.

In particular, we focused on carbonated black pustular mats. It occurred via organo-mineralization processes within a large EPS matrix excreted by the diverse microbial consortium associated with Rivularia where diatoms and anoxygenic phototrophic bacteria were particularly abundant. By structuring a large microbial consortium, Rivularia should then favor the formation of organic-rich laminations of carbonates that can be preserved in stromatolites. By using Fourier Transform Infrared spectroscopy and Synchrotron-based deep UV fluorescence imaging, we compared laminations rich in structures resembling Rivularia to putatively chemically-precipitated laminations in oncoids associated with the mats.

We showed that they presented a different mineralogy jointly with a higher content in organic remnants, hence providing some criteria of biogenicity to be searched. This article aims to make a reading of the social role ofthe slave in Brazil regency period, highlighting the feminist aspects of the black women fight against captivity and for the maintenance of the family unit formed in the colony. She is pointed by feminist scholars as the one that did the History of Brazil homework, contrary to the myth propagated by Gilberto Freire work that there was a harmonius relationship between the big house and the slave quarters, which fed the possibility of social mobilitiy to the Brazilian slaves.
