Abstract:
We interpret borehole geophysical logs in conjunction with lithology developed from continuous core to produce high-resolution hydro- and geo-stratigraphic profiles for the drillhole CR-622 (Strat 8) in the Atlantic Coastal Plain of North Carolina. The resulting hydrologic and stratigraphic columns show a generalized relation between hydrologic and geologic units. Fresh-water aquifers encountered are the surficial,Yorktown, Pungo River and Castle Hayne.Geologic units present are of the middle and upper Tertiary and Quaternary periods, these are the Castle Hayne (Eocene), Pungo River (Miocene), Yorktown (Pliocene), James City and Flanner Beach (Pleistocene), and the topsoil (Holocene). The River Bend Formation (Oligocene) is missing as a distinct unit between the Pungo River Formation and the Castle Hayne Formation. The confining unit underlying the Yorktown Aquifer corresponds to the Yorktown Geologic Unit. The remaining hydrologic units and geologic units are hydrologically transitional and non-coincident. The lower Pungo River Formation serves as the confining unit for the Castle Hayne Aquifer, rather than the River Bend Aquifer, and separates the Pungo RiverAquifer from the upperCastle Hayne Aquifer. All geologic formations were bound by unconformities. All aquifers were confined by the anticipated hydrologic units. We conclude that CR-622 (Strat 8) represents a normal sequence in the Atlantic Coastal Plain.

Abstract:
Despite the diligent efforts of archivists, there are a number of fifteenth-century composers for whom are lacking most or all of their biographical details. Not all of these are minor figures. Caron, Hayne van Ghizeghem and Loyset Compère were all active composers who achieved a large degree of contemporary esteem, evidenced not only by the number of concordances but even by direct references. Yet Caron has become so obscure that not even his forename is certain. Hayne van Ghizeghem disappears from Burgundian records while still a relatively young man. There are no records at all for Compère's early years, and his later career is plagued by gaps. At this point, it is not likely that much more documentation will be found to shed light on any of these individuals.

Abstract:
Hymenaea martiana Hayne belongs to the family Fabaceae (Leguminosae) and presents the popular name of jatobá. It is a tree that demonstrates medicinal purposes and represents a food source in Brazil. The potential contribution of each species to recommended nutrient intakes (DRI) and Brazilian Health Surveillance Agency (ANVISA) for children and adults were calculated. A comparison between the quantified contents of micro- and macronutrients Al, Ca, Cr, Cu, Fe, K, Mg, Mn, Na, Ni, P, S, and Zn in leaves tea and tea of the bark of this plant was made with the recommendation of FDA and ANVISA. General safety regarding metal content (Na, K, Ca, Fe, Zn, and Ni) and nonmetal (P) was assured as none of them exceed the safety limit of the daily intake. However, the content of Mn observed in the teas of H. martiana Hayne is above the UL for tolerable intake level for children aged 1-6 years. There are no limits established for the UL of Cr and S for children and adults. The data on quantification of mineral concentration in the species Hymenaea martiana Hayne obtained can serve as a tool to decide the dosage of preparations from this plant used for medicinal purposes.

Copaifera multijuga Hayne is a large plant species, popularly known as copaiba, native to Latin America and Africa. They are widely used in Amazonian folk medicine, due to the properties of oleoresin extracted from the trunk of their trees, mainly used as: diuretic, laxative, anti-tetanic, anti-inflammatory, antitussive, healing and anti-tumor. Therefore, it is of great importance for research aimed at identifying in plants substances with potential medical and biotechnological purposes. Therefore, this work aimed to search for the transcriptome of C. multijuga Hayne, which was sequenced using the Roche 454 platform, obtaining a total of 638,576 reads, assembled using the de novo methodology using the MIRA and TRINITY platforms. Being generated, from the assembly by TRINITY 53.319 contigs and 62.839 by assembly MIRA. The transcriptome annotation was performed using BLASTx (NCBI) and the functional annotation through the Gene Ontology (GO) bank. The results were categorized according to GO, where the contigs were grouped in the categories: "Cell Component" with 6.249 contigs involved in this category, "Molecular Function" with a total of 17.208 contigs and "Biological Process" with 9,499 contigs. In the three categories the contigs evidenced are involved in the primary plant metabolism. A total of 184 unigenes were detected in 22 clusters, mainly involved in responses to plant oxidative stress, terpenes, important metabolites involved in the formation of copaiba oleoresin, diterpenes (resinous portion of oleoresin) and sesquiterpenes (volatile components of oil) and unigenes related to vegetal pigmentation such as: flavonoids, carotenoids and anthocyanins. In phylogenetic analysis, evolutionary comparisons of terpene synthase enzymes, copaiba oil formation components, with enzymes from the NCBI database were made. C. multijuga TPS4-2 unigene had similarity to other Copaifera TPS4-2 terpene sequences available from the bank. Thus, in this work the transcriptome of C. multijuga was carried out with new assembly and annotation, which leads to the perspective of studies with the unigenes encoding enzymes components of the oleoresin evidenced in this work, aiming with this future research for biotechnological purposes.

A anotação do transcriptoma foi realizada utilizando BLASTx (NCBI) e a anotação funcional através do banco Gene Ontology (GO). Os resultados obtidos foram categorizados de acordo com GO, onde os unigenes foram agrupados nas categorias: “Componente Celular” com 6.249 contigs envolvidos nesta categoria, “Função Molecular” com total 17.208 contigs e “Processo Biológico” com 9.499 contigs. Nas três categorias os contigs evidenciados estão envolvidos no metabolismo primário vegetal. Já do metabolismo secundário foram detectados 184 unigenes, sendo organizados em 22 clusters, envolvidos principalmente em respostas ao estresse oxidativo vegetal, compostos terpenos, importantes metabólitos envolvidos na formação do óleo-resina de copaíba, diterpenos (porção resinosa do óleo-resina) e sesquiterpenos (componentes voláteis do óleo) e unigenes relacionados com a pigmentação vegetal tais como: flavonóides, carotenóides e antocianinas. Na análise filogenética foram feitas comparações evolutivas de enzimas de terpenos sintases, componentes de formação do óleo de copaíba, com enzimas do banco de dados NCBI. O unigene de TPS4-2 de C. multijuga mostrou-se mais próximo a outras sequências de terpenos TPS4-2 de Copaifera disponíveis no banco. Com isto, neste trabalho realizou-se o transcriptoma de C. multijuga com a montagem de novo e anotação o que leva a perspectiva de estudos com os unigenes codificadores de enzimas componentes do óleo-resina evidenciados neste trabalho, visando com isto futuras pesquisas para fins biotecnológicos.

Abstract:
Dabar Lietuvoje yra žinomos dvi linlapio genties rūšys: plikažiedis linlapis (Thesium ebracteatum Hayne) ir melsvasis linlapis (Thesium linophyllon L.). Abi šios rūšys Lietuvoje saugomos (T. ebracteatum saugomas nuo 2003 metų, o T. linophyllon – nuo 2007 metų) ir priskiriamos pažeidžiamų rūšių kategorijai 2(V). Plikažiedis linlapis įtrauktas į Europos Sąjungos buveinių direktyvos II priedą. Linlapio (Thesium) genties populiaciniai tyrimai vygdyti 2003 ir 2006 m. birželio–liepos mėn. Tirtos 5 plikažiedžio linlapio cenopopuliacijos. Darbo tikslas buvo atlikti plikažiedžio linlapio (T. ebracteatum) populiacijų tyrimus ir nustatyti augalų būklės priklausomybę nuo buveinės sąlygų. Nustatyta, kad gausios ir geros būklės T. ebracteatum cenopopuliacijos auga atvirose, gerai apšviestose buveinėse. Čia augalai būna vešlesni ir gausiau žydi, o pievoms ir šlaitams užžėlus medžiais ir krūmais, susidarius pavėsiui augalai beveik nežydi, liaujasi daugintis sėklomis, išaugina tik vegetatyvinius ūglius. Labai neigiamai plikažiedžio linlapio cenopopuliacijas veikia susikaupiančios ir dirvožemio paviršių uždengiančios nuokritos (lapai, spygliai, sausos žolės, šakelės) ir stora samanų danga. Atlikti tyrimai parodė, kad didžiausias ir statistiškai patikimas koreliacinis ryšys T. ebracteatum sieja su Medicago falcata ir Knautia arvensis. Taigi šios rūšys gali būti laikomos potencialiais T. ebracteatum šeimininkais. Apsaugoti plikažiedžio linlapio populiacijas ir išlaikyti arba pagerinti jų būklę... [toliau žr. visą tekstą]
The genus Thesium in Lithuania is represented by 2 species: Thesium ebracteatum Hayne and T. linophyllon L.. Both these species are included into the Red Data Book of Lithuania (T. ebracteatum under protection is since 2003 and T. linophyllon – is protected since 2007). Both Thesium species are ascribed to the group of vulnerable species. Furthermore, T. ebracteatum is included in to the Annex II of the EU Habitat Directive. Investigations on cenopopulations of T. ebracteatum were performed in 2003 and 2006 during June–July. Five cenopopulations were investigated. The aim of this study was to investigate populations of T. ebracteatum and to reveal dependence of population state upon habitat conditions. The study revealed that abundant and viable cenopopulations of T. ebracteatum usually occur in open, well-illuminated sites. Individuals of this species, as a rule, are well developed, with higher number of flowers. When meadows and slopes overgrow with shrubs and trees, because of law illumination T. ebracteatum flowers poorly, does not reproduce by seeds and occurs as vegetative shoots only. Accumulation of dead herb and leaf litter as well as dense and thick moss cover influence coenopopuliations of T. ebracteatum especially negatively. Results of this investigation revealed strong positive correlation between abundance of Medicago falcata and Knautia arvensis in the habitat. These species are, probably, important host plants for Thesium ebracteatum. In order to sustain or... [to full text]

Comumente chamada de “copaíba”, a Copaifera multijuga Hayne (CmH) é uma planta do gênero Copaifera (Leguminosae-Caesalpinoideae) que ocorre na Amazônia brasileira. Extraído do tronco das árvores, o óleo-resina de Copaifera spp. é amplamente utilizado por povos indígenas da região amazônica na medicina popular e tem alto potencial associado a aplicações biotecnológicas como agente antimicrobiano, anti-inflamatório, antitumoral, antinociceptivo, antileishmanial e cicatrizante. O óleo-resina de Copaifera spp. é composto por ácidos resinosos e compostos voláteis, principalmente sesquiterpenos e diterpenos Neste trabalho, sesquiterpenos do óleo-resina da CmH, cenários biológicos para sua biossíntese e seus mecanismos químicos foram coletados de vários estudos. Com base nessa coleta de dados, em dados de um transcritoma da CmH e em métodos e ferramentas computacionais, foi reconstruída in silico uma rede metabólica de sesquiterpenos de Copaifera multijuga Hayne (CmH). Esta rede metabólica é uma compilação de reações enzimáticas cobrindo mecanismos de ciclização, compostos preditos e cenários biológicos para a biossíntese. Os resultados foram convenientemente armazenados em um banco de dados em grafos projetado especificamente para esta finalidade, tornando-se localizáveis, acessíveis, interoperáveis e reutilizáveis. O workflow utilizado para a reconstrução in silico funciona para múltiplos organismos, bem como pode ser adaptado para diferentes tipos de mecanismos químicos alterando o conjunto de regras de gramática de grafos.
Ordinarily named “copaiba”, the Copaifera multijuga Hayne (CmH) is a plant of Copaifera genus (Leguminosae-Caesalpinoideae) occurring in the Brazilian Amazon. Exuded from the trunk of trees, the oil-resin of Copaifera spp. is widely used by indigenous people from the Amazon region for healing and in folk medicine, and it has high associated potential biotechnological applications, such as antimicrobial, anti-inflammatory, antitumor, antinociceptive, antileishmanial and healing. The oil-resin of Copaifera spp. is composed of resinous acids and volatile compounds, mainly sesquiterpenes and diterpenes In this study, a range of CmH oil-resin sesquiterpenes, biological scenarios for their biosynthesis, and its chemical mechanisms were collected from several studies. Based on this data collection, on CmH transcriptome data, and on computational methods and tools, an in silico sesquiterpene metabolic network of Copaifera multijuga Hayne (CmH) was reconstructed. The resulting sesquiterpene metabolic network of CmH is a compilation of reactions covering cyclization mechanisms, predicted compounds, and biological scenarios for the biosynthesis. These results were suitably stored in a graph database designed for it, and they became findable, accessible, interoperable, and reusable. The workflow for the in silico reconstruction can be used for multiple organisms as well as graph grammar rules can be added or removed to achieve different types of chemical mechanisms.

As árvores do gênero Copaifera (Leguminosae), conhecidas popularmente como copaibeiras, exsudam um óleo-resina extensamente utilizado na medicina popular e por indústrias farmacêuticas e de cosméticos, devido às suas atividades cicatrizante e anti-inflamatória. Quimicamente, esses óleos se caracterizam pela presença de hidrocarbonetos sesquiterpênicos, sesquiterpenos oxigenados e ácidos diterpênicos. No entanto, a composição química desses óleos-resina é variável e ainda não se tem conhecimento dos fatores que as determinam, embora vários fatores bióticos e abióticos sejam considerados fontes dessa variação. Essa variação dificulta a padronização da composição química desses óleos, comprometendo seu controle de qualidade e consequentemente a qualidade dos produtos a que darão origem, fato que tem causado um grande entrave à sua maior aplicação e comercialização. Essa variabilidade em sua composição química já é bastante conhecida e relatada na literatura, mas a maioria dos estudos realizados têm se restringido a caracterizar quimicamente o óleo-resina e poucos tem se preocupado em estudar as causas dessas variações. O objetivo deste trabalho foi padronizar a composição química dos óleos de copaíba por meio de técnicas de cromatografia em fase gasosa acoplada à detectores de ionização de chama (CG-DIC) e espectrometria de massas (CG-EM) e cromatografia em fase gasosa bidimensional abrangente (CGXCG); analisar estatisticamente a influência de fatores abióticos como sazonalidade, tipo de solo e diâmetro à altura do peito (DAP), além da infestação por cupins, sobre a composição química desses óleos. Além disso, foram comparados 5 métodos de esterificação dos ácidos diterpênicos presentes nos óleos de copaíba envolvendo catálise ácida, que utilizam BF3/MeOH, H2SO4/MeOH e HCl/MeOH, levando-se em consideração suas eficiências e frequências analíticas, além do consumo e toxicidade dos reagentes utilizados, relação custo benefício e, principalmente, a possibilidade de alteração/degradação da estrutura dos constituintes quando aplicados em óleos de copaíba. Para isso foram obtidos óleos de copaíba de 3 coletas: em novembro de 2004 e novembro de 2005 (épocas consideradas secas) e em maio de 2005 (época considerada chuvosa). No total, 43 amostras de óleo-resina de copaíba foram coletadas na Reserva Ducke (Manaus-AM), de 33 espécimes diferentes, que possuíam diferentes DAP s e se encontravam em diferentes tipos de solo. As análises por CG-DIC e CG-EM permitiram a identificação de 35 constituintes: sendo 22 hidrocarbonetos sesquiterpênicos, 9 sesquiterpenos oxigenados e 4 ácidos diterpênicos. Enquanto a análise por CGxCG permitiu a identificação de outros 13 sesquiterpenos, além de 7 monoterpenos, inéditos em óleos-resina de copaíba. O β-cariofileno e seu óxido foram os constituintes majoritários em 29 e 11 amostras, respectivamente. As análises hierárquica por agrupamento (HCA) e de componentes principais (PCA) evidenciaram a existência de dois grupos distintos com diferentes perfis cromatográficos, em que foi comprovada apenas a influência do tipo de solo, sobre a composição química desses óleos. Outros fatores analisados como sazonalidade, DAP e infestação por cupins, não tiveram influência sobre a composição química dos óleos-resina de copaíba. Quanto aos métodos de esterificação, as análises das 5 metodologias testadas, apesar de terem sido reprodutíveis, não se mostraram eficientes, ao passo que não permitiram a identificação dos constituintes formados e levaram à formação de artefatos.

Abstract:
As copaíbas, pertencentes à família Leguminosae, subfamília Caesalpinioideae, são conhecidas pela produção de uma óleo-resina com propriedades antiinflamatórias, utilizada na medicina popular e pela indústria farmacêutica. A substância é retirada do tronco da árvore, através do uso de um trado que perfura o caule até que a óleo-resina escorra. Esta óleo-resina parece ser produzida, armazenada e secretada por dois tipos de estruturas secretoras, os canais e as cavidades secretores. Embora muitos trabalhos tratem das análises químicas e das atividades biológicas da óleo-resina de espécies de Copaifera, poucos são os que tratam dos mecanismos subcelulares da produção, do armazenamento e da secreção da óleo-resina. Assim, o objetivo deste trabalho foi estudar comparativamente a distribuição, a morfologia, o desenvolvimento e o conteúdo secretor dos canais e/ou cavidades secretores de óleo-resina no caule e na folha de Copaifera trapezifolia Hayne, única dentre as 35 espécies do gênero que ocorre na Floresta Atlântica. Foi testado se os canais e/ou cavidades secretores produzem óleo-resina na folha, assim como relatado para o caule, a fim de propor alternativas para a utilização do tronco da árvore como fonte da secreção. Como a natureza química da secreção já é conhecida para o caule, o estudo ultraestrutural visa relacionar as populações de organelas às substâncias produzidas, ampliando o conhecimento sobre os mecanismos de produção e secreção de óleo-resina pelas células epiteliais secretoras dos canais e/ou cavidades. Para tal, gemas axilares contendo primórdios foliares e caulinares e folíolos medianos completamente expandidos foram coletados de três indivíduos no Jardim Botânico do Rio de Janeiro, e processados para estudos anatômicos, de histolocalização de óleo-resina, ultra-estruturais e de diafanização de folhas inteiras. Os dados indicam que estruturas com forma isodiamétrica, denominadas cavidades secretoras, ocorrem na folha e no caule em estrutura primária e secundária. Na lâmina foliar, estão localizadas entre os parênquimas paliçádico e lacunoso e na face abaxial da nervura central; no pecíolo as cavidades ocorrem no córtex; no caule ocorrem imersas nos parênquimas cortical e medular. Originam-se de células do meristema fundamental, a partir de uma divisão periclinal seguida de duas anticlinais; o lúmen é originado por esquizogenia. O conteúdo das cavidades tanto do caule como da folha contém óleo e resina, conforme consta na literatura para o gênero. Isto permite inferir que a extração da óleo-resina seria menos prejudicial para a planta se extraída da folha. A presença de um epitélio bisseriado na folha e no caule, assim como o que foi encontrado em C. langsdorffii, constitui um dado inédito para Leguminosae e, provavelmente, representa a reposição das células epiteliais que já secretaram. As células epiteliais, no início da produção dos metabólitos, são polarizadas: núcleo próximo à parede periclinal interna e citoplasma próximo à parede periclinal externa. O citoplasma é rico em mitocôndrias e retículos endoplasmáticos liso e rugoso, associados a vesículas (folha) ou plastídeos (caule). Vesículas de conteúdo distinto (elétron-denso e elétron-opaco) são produzidas nos retículos, transportadas por entre as microfibrilas das paredes anticlinal e periclinal interna e liberadas para o lúmen. Produção e secreção de metabólitos para o lúmen não são sincronizadas nas células epiteliais de uma mesma cavidade. Sugere-se que o componente resinoso seja produzido nos retículos rugosos e plastídeos, e o oleoso nos retículos lisos. A comparação entre C. langsdorffii e C. trapezifolia utilizando caracteres com valor diagnóstico representa um resultado pioneiro se considerado o grande número de espécies e morfo-espécies do gênero. No entanto, a inclusão de um maior número de espécies nos estudos de estruturas secretoras de Copaifera permitiriam auxiliar a delimitação infragenérica do grupo.
Copaíbas (Leguminosae, Caesalpinioideae) are best known for the production of an oilresin with anti-inflammatory properties, used in the folk medicine and pharmaceutical industry. The substance is usually taken from the stem, through the use of an auger to drill the stem until the oilresin drips. This oilresin seems to be produced, stored and secreted by two types of secretory structures, canals and secretory cavities. Although many studies address the chemical analysis and the biological activity of the oilresin in species of Copaifera, the cellular mechanisms of production, storage and secretion have rarely been exploited. The objective of this study was to compare the distribution, morphology, development and secretion biology of oilresin-secreting canals and/or cavities, in the stem and in the leaf of Copaifera trapezifolia Hayne, unique among the 35 species of the genus that occurs in the Atlantic Rain Forest. The study tested wheather canals and/or cavities produce oilresin in the leaf, as reported to the stem, in order to propose alternatives to the use of the trunk of the tree as a source of secretion. Considering that the chemical nature of the secretion is already known to the stem, the ultrastructural study of canal/cavity in several stages of development aim at to associate subcellular components with substances produced and secreted. Data obtained can increase the knowledge on the production and secretion mechanisms of within epithelial cells of secretory canals and/or cavities. Materials include axillary buds containing leaf and stem primordial, besides mature middle leaflets and portions of stem in primary and secondary growth. They were collected from three individuals in the Botanic Garden of Rio de Janeiro and prepared to be employed in anatomy, histolocalization of oilresin, ultrastructure and clearing of whole leaves. Secretory cavities were observed in the leaf and the stem (primary and secondary growth), between the palisade and spongy mesophyll, petiole cortex, and shoot cortex and pith. Cavities originate from ground meristem cells by a periclinal division followed by two anticlinals; the lumen is formed by esquizogenous process. The content of the cavities of both the stem and leaf contains oil and resin, as shown in the literature for the genus. This suggests that the extraction of the oleoresin would be less harmful for the plant if extracted from the leaf. The presence of a biseriate epithelium in foliar and shoot cavities, as similarly found in C. langsdorffii, is a novelty for Leguminosae, and probably represents the replacement of epithelial cells that have secreted. In the beginning of substance production epithelial cells are polarized: nucleus near the inner periclinal wall and cytoplasm near the outer periclinal wall. The cytoplasm is rich in mitochondria, and smooth and rough endoplasmic reticulum associated to vesicles (leaf) or plastids (stem). There is a greater amount of smooth endoplasmic reticulum in cells of the leaf cavities and rough endoplasmic reticulum in cells of the stem cavities. Vesicles with different content (electron-dense and electron-opaque) are produced by the reticulum, transported through microfibrils of anticlinals and inner periclinal walls and released into the lumen. Production and secretion of metabolites are not synchronized in epithelial cells of the same cavity. It is suggested that the resin component is produced in the rough reticulum and plastids, and the oily component in the smooth reticulum. The comparison between C. langsdorffii and C. trapezifolia using characters with diagnostic value represents a pioneer result if considered the number of species and morpho-species of the genus. However, the inclusion of a greater number of species in studies of secretory structures of Copaifera would certainly help the complex infrageneric division of this group.

O óleo de copaíba é usado pela população sendo encontrado em farmácias e outros estabelecimentos. É extraído de espécies de Copaifera (Fabacea), sendo a mais utilizada no Brasil a Copaifera multijuga Hayne. Em sua constituição encontram-se sesquiterpênicos e ác. palmítico. A literatura o atribui ação antiinflamatória, antinociceptiva, antibacteriana e antitumoral. São escassos trabalhos relacionados à sua toxicidade, nesse sentido, procurou-se avaliar a segurança pré-clínica do óleo de C. multijuga (Cm). Para tal, inicialmente confirmou-se a atividade antiinflamatória e antinociceptiva por via oral do óleo nos modelos de peritonite (Cm 200 mg/kg) e de contorções abdominais (Cm 50 a 200 mg/kg), posteriormente foi realizado o teste de toxicidade aguda (DL50) em ratos e finalmente os ensaios por via oral de toxicidade de dose repetida por 4 e 8 semanas em ratos Wistar e 4 semanas em coelhos Nova Zelândia, seguindo os critérios norteadores da ANVISA. Os resultados mostram que o óleo (200 mg/kg) reduziu em 28% o número de leucócitos circulantes, após estímulo com carragenina e que todas as doses (50 – 200 mg/kg) inibiram as contorções abdominais por ác. acético. Na toxicidade aguda não houve morte até a dose de 4,0 g/kg o que revela baixa toxicidade por via oral. Em ratas, a administração do óleo (Cm 200, 500 e 2500 mg/kg) por via oral não produziu mortes ou alteração comportamental, entretanto, houve aumento do ganho de massa, para Cm 200 mg/kg e redução para Cm 2500 mg/kg. O consumo de água aumentou para Cm 2500 mg/kg ao final de 8 semanas. Nos ratos, não houve mortes ou alteração comportamental, mas Cm 2500 mg/kg reduziu a massa corporal na 5ª e 6ª semana e aumentou o consumo de água já na 3ª semana de administração. Os parâmetros hematológicos em ratos de ambos os sexos não foram alterados. Enquanto que nos parâmetros bioquímicos em ratas, avaliados na 4ª semana registrou-se que Cm 2500 mg/kg aumentou os níveis séricos de creatininia (creat), col. VLDL, triglicerídeos (trig), fosfatase alcalina (FA), bilirrubinas T e D (BT e BD), albumina e amilase (amil) e a dose de 500 mg/kg aumentou os níveis de amilase. Ao final da 8ª semana, Cm 2500 mg/kg aumentou creat, col. VLDL, trig, BT e BD, enquanto Cm 500 mg/kg elevou col. VLDL e trig. Nos machos, ao final da 4a semana, Cm 2500 mg/kg aumentou creat, FA, BT e BD e prot. total e nas doses de 500 e 200 mg/kg aumentou creat. Na 8ª semana, Cm 2500 mg/kg aumentou ureia, creat, col. HDL, FA, BT e BD, albumina, amilase e lactato desidrogenase (LDH), Cm 500 mg/kg, aumentou BD e LDH e Cm 200 mg/kg aumentou BD. Em coelhos de ambos os sexos, Cm 2500 mg/kg aumentou creat, col. total e LDL e BT e BD. Na morfologia de ratos, observaram-se alterações pontuais nas massas absolutas ou relativas no fígado, estômago e adrenal, contudo a análise microscópica dos tecidos não revelou nenhuma alteração. Na toxicidade reprodutiva, o óleo em todas as doses reduziu a massa corporal das mães durante o período de gestação e a massa absoluta dos fetos. Houve também aumento do consumo de água no 14º e 20º dia. Na performace reprodutiva dos machos, o óleo não alterou os parâmetros reprodutivos, assim como, não foram constatadas alterações nos indicadores comportamentais da prole. E finalmente observou-se alteração nos parâmetros globais de avaliação renal em ratos tratados por quatro semanas. Desta forma conclui-se que o óleo possui baixa toxicidade, contudo, merece destaque o possível efeito tóxico materno durante a gestação e sobre a função renal que requerem estudos mais detalhados.

Abstract:
The Castle Hayne Limestone (Middle Eocene, North Carolina), noted for its diverse macro-invertebrate fossils, was sampled to assess if early Cenozoic brachiopods from eastern North America record any traces of biotic interactions. Systematic surveys of two North Carolina quarries yielded 494 brachiopods, dominated by one species: Plicatoria wilmingtonensis (Lyell and Sowerby, 1845). Despite subtle variations in taphonomy, taxonomy, and drilling patterns, the two sampled quarries are remarkably similar in terms of quantitative and qualitative paleoecological and taphonomic patterns. Ninety-two brachiopod shells (18.6% specimens) contained a single circular hole. Majority of drillholes were singular, perpendicular to shell surface, and drilled from the outside. In addition, ventral valves were drilled slightly more frequently than dorsal ones and larger brachiopods contained more drillholes than smaller ones. However, the size of drillholes did not correlate with the size of brachiopods. The drillholes record â live-liveâ biotic interactions, which may represent either predatory attacks or parasitic infestations or combination of those two types of interactions. A notable fraction of specimens bears multiple drillholes, which is consistent with either parasitic nature of interactions or frequent failed predatory events. Drilling frequency was high in both quarries (24.5%); this high frequency reinforces other recent reports (from other continents and Cenozoic epochs) that drilling organisms may be a frequent predator or parasite of brachiopod prey or hosts. The number of case studies reporting high frequencies of drilling in brachiopods is still limited and thus insufficient to draw reliable generalizations regarding the causes and consequences of these occasionally intense ecological interactions.

Abstract:
A participação da tecnologia na sociedade tornou-se cada vez mais presente, seja ela no âmbito social ou econômico. Conforme Hayne; Wyse (2018), em pleno século XXI vive-se um processo de globalização, onde a quebra de barreiras econômicas é marcada pela flexibilidade de recursos, sendo esse cenário responsável pelo avanço da tecnologia de automação e ponta. O que tem culminado com o nascimento de muitas empresas nesse setor. De acordo com estudo publicado pela KPMG (2021), no ranking setorial de transações, acumulado de 2001 a 2020, o setor de tecnologia da informação lidera os números de fusões e aquisições no mercado brasileiro, com 1.638 transações, seguida pelo setor de empresas de internet, com 1.246. Ao analisar os números ao longo dos últimos cinco anos do estudo, o setor de TI figurou em segundo colocado no ranking, sempre atrás do setor de empresas de internet, com exceção a 2016, onde houve a inversão.

Full text
Abstract:
HAYNES 230 and 617 alloys are competing for use on Generation IV, high temperature gas cooled reactor components because of their good high temperature creep strength in the temperature range of 760°C and 982°C and resistance to attack in the gas cooled reactor environment. A review of the metallurgy affecting the properties in each alloy is provided. It is shown that the grain size and carbide precipitation developed during manufacture affect short term and long term ductility, fatigue life, and creep strength. For example, 230 alloy has a finer grained structure which promotes fatigue strength with a slight sacrifice in creep strength. The 617 alloy has a coarser grain structure which provides slightly higher creep resistance while sacrificing some fatigue strength. Thermal aging also introduces gamma prime precipitation to 617 alloy in addition to grain boundary carbides. This, along with grain boundary oxidation, reduces the low cycle fatigue strength of 617 alloy compared to 230 alloy. Independent studies have shown that 230 alloy possesses higher resistance to thermal fatigue than 617 alloy. However, welds of both base metals with similar weld composition have about the same thermal fatigue life. Cooling rates from solution annealing temperatures during processing affect the ductility and creep strength of these alloys with the highest cooling rates preferred for retention of ductility and creep strength. Slow cooling rates promote carbide precipitation in the grain boundaries which reduces ductility and creep strength.

Abstract Prior to utilizing new advanced materials in coal power plants, a large number of experimental testing is required. Test procedures are needed in specialized high temperature laboratories with state of the art facilities and precise, accurate analytical equipment capable of performing tests at a variety of temperatures and environments. In this study, the results of a unique technique involving salt spray testing at high temperatures are presented. The Haynes 282 gamma – prime (γ’) strengthened alloy fabricated by means of three different manufacturing processes: HAYNES 282 WROUGHT alloy, Haynes 282-SINT alloy, and finally Haynes 282-CAST alloy have been tested. The materials have been exposed to a salt spray corrosion atmosphere using 1% NaCl - 1% Na2SO4. Post exposure investigations have included SEM, EDS and XRD examinations. The test using salt spray of 1% NaCl - 1% Na2SO4 water solution at 550 °C for 500 hours indicted no influence on the corrosion products formation, where Cr2O3 has been developed in all three alloys, whereas NiO has been found only in Haynes 282-CAST material. On the other hand, it has been found that the fabrication process of HAYNES 282 alloy strongly influences the corrosion products formation under the high temperature exposures.

Abstract:
Abstract Haynes 188 is a cobalt-based superalloy used in hot section gas turbine components due to its excellent oxidation resistance and elevated temperature stability. Parts made from Haynes 188 are traditionally manufactured from wrought or forged material. Additive manufacturing (AM) may be a less time consuming and more cost-effective alternative, particularly for replacement parts. Additionally, necessary design changes can be quickly introduced into service using additive manufacturing. It is important to understand the effect of long-term thermal exposure on additively manufactured parts before they are put into demanding high temperature applications. Data on the effect of long-term thermal exposure on wrought Haynes 188 is readily available in the open literature. However, such data for additively manufactured Haynes 188 is scarce. This paper discusses an experimental study that investigated the microstructural evolution in wrought and AM Haynes 188 under long-term thermal exposure. Optical metallography and scanning electron microscopy (SEM) were performed on wrought and AM Haynes 188 in the virgin and long-term thermally exposed conditions. Mechanical test samples from the coupons were then extracted and tested in both conditions. Lastly, the fracture surfaces of the mechanical test specimens were evaluated by SEM fractography and metallography of sections through the fracture surfaces. The findings help to understand how long-term thermal exposure affects the microstructure and mechanical properties of wrought and AM Haynes 188. Most importantly, it illustrates a significant difference in microstructural response of the two materials to long term thermal exposure and its effect on mechanical properties.

Abstract:
The purpose of this study was to optimize and compare several different mathematical models using the experimentally determined PVTx density data of Haynes, et al. (1976), Haynes and Hiza (1976), Hiza, et al. (1976), and Hiza (1976). These data are for the liquid phase of methane, ethane, propane, normal butane, isobutane and nitrogen, and various mixtures thereof. The temperature range of the correlations was limited (95-150 K) and the pressures to those of saturation, the range of which was about 0 to 20 atmospheres. The goals of the study were to produce one or more computer models which would predict a density of LNG (liquefied natural gas) to within 0.1% of the true value when the temperature, pressure, and composition of the LNG are specified.

Abstract:
Hanne Darboven’s (1941-2009) Opus 17a is a composition for solo double bass that is rarely performed due to the physical and mental challenges involved in its performance. It is one of four opuses from the composers monumental 1008 page Wünschkonzert (1984), and was composed during her period of making “mathematical music” based on mathematical systems where numbers were assigned to certain notes and translated to musical scores. It can be described as large-scale minimalism and it is highly repetitive, but even though the same notes and intervals keep repeating, the patterns slightly change throughout the piece. This is an attempt to unfold the many challenges of both interpreting, preparing and performing this 70 minute long solo piece for double bass consisting of a continuous stream of eight notes. It is largely based on my own experiences of preparing, rehearsing and performing Opus 17a, but also on interviews I have conducted with fellow bass players Robert Black and Tom Peters, who have both made recordings of this piece as well as having performed it live. One is met with few instrumental technical challenges such as fingering, string crossing and bowing when performing Opus 17a, but because of its long duration what one normally would take for granted could possibly prove to be challenging.
