Generally, synthetic astaxanthin is used to maintain and enhance the skin color of ornamental fish. However, it is expensive and cause increasing cost production of aquaculture because of feed cost. ...Therefore, it should be looked for alternative ingredient for skin coloration to replace high price of synthetic astaxanthin with cheaper and locally available product. The objective of this study was to evaluate the influence of different dosage of red dragon fruit peel meal as an alternative pigment source on the skin coloration of ornamental koi carp fish (Cyprinus carpió). Three experimental diets were formulated with three different dosages of red dragon fruit by product meal (RDFM), namely 5% (Diet A), 10% (Diet B) and 15% (Diet C) of RDFM in the diet and one of commercial diet (Diet D) as a control diet. A total of 60 koi carp (initial weight: 1.43±0.14 g) were distributed in 12 glass tanks (5 fish/tank) size: 20x20x35 cm. The fish were fed diet in two times a day (08.00 a.m. and 04.00 p.m.) and till satisfied for 42 days of feeding trial. Variables observed were weight gain, skin color brightness and survival rate. The skin color brightness was determined by using Toca Colour Finder methods. After six weeks of feeding, there were significant differences (p<0.05) in skin coloration in orange. The fish fed with the diet containing 15% of RDFM has a more intense orange color (3.5 of 4 value) and black color (4.3 of 5 value), respectively. This study concluded that supplementation of 10% RDFM in the diet could be added into the diet to enhance skin coloration of koi carp.
The 404.5m deep SDJ1 borehole is located in the Jongeis mining sector of the Santa Susana Basin (SSB), and has been palynostratigraphically studied. The SSB is a Carboniferous coal-bearing basin ...developed along the suture contact between the Ossa Morena Zone (OMZ) and the South Portuguese Zone (SPZ).
The recovered palynologic assemblages are assigned to the NM Miospore Biozone of mid Visean age, with the lowermost 6.8m of the borehole yielding an in situ miospore assemblage assigned to the SL Miospore Biozone of mid Moscovian age. All of the studied samples contained more than 90% of reworked palynomorphs ranging in age from the middle Cambrian to the early Tournaisian (0–397.7m depth), with the first 6.8 m (397.7–404.5m depth) yielding reworked palynomorphs from the middle Cambrian to the mid Moscovian. This particular palynologic signature provides further evidence for the interpretation of the reworked palynomorphs in the Toca da Moura Complex (TMC) and its importance in the geodynamic evolution of the OMZ, regarding the probable provenance areas of the reworked palynomorphs within the OMZ and SPZ. Six reworked sub-assemblages were discriminated: i. middle to (?)upper Cambrian; ii. Lower to Middle Ordovician; iii. middle to upper Silurian; iv. Lower Devonian; v. Upper Devonian and vi. lower Carboniferous.
From the study of the palynomorph assemblages (both in situ and reworked) recovered from the SDJ1 borehole samples, new inferences are made regarding the recognition of the subsurface extension of the Toca da Moura Complex and its structural relationship to the Pennsylvanian continental coal-bearing SSB. These new data, together with the palynologic study of a control sample (STS15) from the Jongeis old coal mine, housed in the LNEG Geological Museum, in Lisbon, makes possible new interpretations concerning the evolution of the SSB.
•Visean and Moscovian miospores recovered from SDJ1 borehole (Ossa Morena Zone).•Reworked miospores make the bulk of the palynomorphs.•Six reworked sub-assemblages of Cambrian to Lower Carboniferous were identified.•Source of reworked assemblages can be traced in Ossa Morena and South Portuguese Zone.•Reworked signature allows new interpretations of variscan geodynamic evolution.
The Mississippian volcano-sedimentary complex in the Toca da Moura – Cabrela areas represents remnants of intra-volcanic marine sedimentary basins, formed during the collision between the Ossa Morena ...Zone with the South Portuguese Zone. These rock units are unconformably overlain by the Pennsylvanian intramontane coal-bearing Santa Susana Basin. Vitrinite reflectance determinations from rocks of these two basins indicate two episodes of thermal maturation. During the first episode, the Toca da Moura – Cabrela volcano-sedimentary complexes attained high maturation levels, equivalent to anthracite coal rank (3.0–3.5% Roran
), which pre-dates the middle Moscovian Santa Susana Basin. The Santa Susana Basin attained moderate maturation levels equivalent to bituminous coal rank (1.35–1.5% Roran
) recording a second episode of thermal maturation. Here, peak thermal conditions did not overprint the first maturation episode. The observed effects of magmatic intrusion on the thermal maturity and the lack of any increase in vitrinite reflectance with depth through c. 400 m of section in borehole SDJ-1 indicate high geothermal gradients during the first maturation episode. A contemporaneous magmatic event associated with the c. 335–320 Ma Cuba-Alvito Gabbros/Diorites of the Beja Massif was the possible cause for the high geothermal gradients postulated for the first maturation episode. Burial under a post-upper Moscovian sedimentary cover was the most likely process to account for the maturation levels determined for the Santa Susana Basin and for the second episode of thermal maturation.
O presente estudo busca compreender a aderência de jovens a um instituto católico – Toca de Assis – que se caracteriza por adotar um estilo de vida configurado por radical pobreza, renúncia a bens e ...estudos formais, e dependência exclusiva da providência divina, além de desenvolvimento de trabalho com pessoas em situação de rua. Busca entender a opção juvenil por um estilo de vida religiosa rigoroso a partir de propostas de vida contrastivas com a sociedade contemporânea e, de certo modo, com a própria Igreja, visando identidades alternativas e fortes. Assim, o artigo desenvolve o tema Juventude; Toca de Assis, renúncia, pobreza; tem como objetivo verificar as relações entre juventude, comportamento e adesão a estilos de vida radicais; usa, principalmente, da metodologia das ciências sociais; tem por conclusão provisória a compreensão de que os jovens que aderem à Toca de Assis, ao renunciar a bens materiais, estudo, e ao assumirem uma vida de pobreza e solidariedade com os pobres, estão em um movimento de contrastividade e contestação social motivadas por uma identificação com o Cristo sofredor. Palavras-chave: Toca de Assis. Renúncia. Pobreza. Jovens. Abstract: The present study aims to understand the adherence of youth people to a Catholic institute called Toca de Assis. This group adopts a lifestyle of radical poverty, wich calls for renunciation of material goods and also to formal studies. Participants in this group also claim rely solely on state of divine providence for their material survival. Young people in this group perform a work of assistance to people marginalized by society and to those who live at risk on the streets. The article seeks to understand the reasons for the choice of young people for a religious lifestyle so strict that contrasts with the lifestyle of contemporary society and in a sense, the Church itself, aiming at the formation of alternate identities. Thus, the article develops the theme “youth”, “Toca de Assis”, “resignation”, and “poverty”. The study aims, in short, to examine relationships between youth behavior and adherence to radical lifestyles; For this purpose, a methodology of social science is used. As in interim conclusion, this discussion indicates the following: youth people who adhere to Toca de Assis, renouncing material possessions, study, and assuming a life of poverty and solidarity with the poor, are in a movement of social protest and are motivated by an identification with the suffering Christ. Keywords: Toca de Assis. Renunciation. Poverty. Youth.
This work reports the dating of a fossil human tooth and shell found at the archaeological site Toca do Enoque located in Serra das Confusões National Park (Piauí, Brazil). Many prehistoric paintings ...have been found at this site. An archaeological excavation unearthed three sepulchers with human skeletons and some shells. Two Brazilian laboratories, in Ribeirão Preto (USP) and Recife (UFPE), independently performed Electron Spin Resonance (ESR) measurements to date the tooth and the shell and obtain the equivalent dose received by each sample. The laboratories determined similar ages for the tooth and the shell (~4.8 kyBP). The results agreed with C-14 dating of the shell and other samples (charcoal) collected in the same sepulcher. Therefore, this work provides a valid inter-comparison of results by two independent ESR-dating laboratories and between two dating methods; i.e., C-14 and ESR, showing the validity of ESR dating for this range of ages.

The age and depositional history of Dominican amber-bearing deposits have not been well constrained. Resinites of different ages exist in Hispaniola, but all of the main amberiferous deposits in the ...Dominican Republic (including those famous for yielding biological inclusions) were formed in a single sedimentary basin during the late Early Miocene through early Middle Miocene (15 to 20 million years ago), according to available biostratigraphic and paleogeographic data. There is little evidence for extensive reworking or redeposition, in either time or space. The brevity of the depositional interval (less than 5 million years) provides a temporal benchmark that can be used to calibrate rates of molecular evolution in amber taxa.
This study compared 5 scoring methods in terms of their statistical assumptions. They were then used to score the Teacher Observation of Classroom Adaptation Checklist, a measure consisting of 3 ...subscales and 21 Likert-type items. The 5 methods used were (a) sum/average scores of items, (b) latent factor scores with continuous indicators, (c) latent factor scores with ordered categorical indicators using the mean- and variance-adjusted weighted least squares estimation method, (d) latent factor scores with ordered categorical indicators using the full information maximum likelihood estimation method, and (e) multidimensional graded response model using the Bock-Aitkin expectation-maximization estimation procedure. Measurement invariance between gender groups and between free/reduced-price lunch status groups was evaluated with the second, third, fourth, and fifth methods. Group mean differences based on the 5 methods were calculated and compared.

The earliest agglutinated pectinariid-like tube with a modern appearance is described from the Late Cretaceous (Santonian, ∼84 My) of Colombia. The rare agglutinated fossil tube is composed of sorted ...skeletal material, quartz sand, and unidentified carbonaceous fragments. It's solitary and non–encrusting life mode, the straight conical shape, and the agglutinated tube wall composed of sand-sized grains, supports affinity with the tube-building Family Pectinariidae. This finding suggests that Pectinariidae might have first appeared in the Neotropics at least by the late Mesozoic.
► Earliest modern agglutinated pectinariid-like tube from the Late Cretaceous. ► Rare agglutinated fossil tube is composed of sand grains. ► Pectinariidae originated at latest in the Mesozoic.
Esta pesquisa objetivou estudar as práticas funerárias realizadas nos nove enterramentos evidenciados no sítio Toca da Baixa dos Caboclos/PI. Fundamentada em uma perspectiva conservadora, este estudo ...defendeu a hipótese de que a manutenção do sítio como espaço funerário poderia apontar a manutenção das próprias práticas funerárias dispensadas aos enterramentos nele evidenciados. Buscando validar esta hipótese, este trabalho se utilizou de uma metodologia ordenada e sistemática que permitiu reconstituir o Perfil Funerário do Sítio Toca da Baixa dos Caboclos, a partir da reconstituição dos seus respectivos Perfis das Unidades Funerárias. Segundo esta metodologia foi possível tecer considerações sobre as práticas funerárias dispensadas particularmente a cada enterramento e, ao mesmo tempo, entre todos os enterramentos estudados. Concomitantemente, o estudo da distribuição crono-espacial dos enterramentos possibilitou inferências acerca do aproveitamento do espaço interno do sítio, em distintos momentos cronológicos. Como resultado, foram identi&cadas recorrências relacionadas às práticas funerárias e também ao próprio agenciamento do espaço funerário. ABSTRACT This research aimed to study the funerary practices realized in nine burials evidenced in the archaeological site Toca da Baixa dos Caboclos/PI. Based on a conservative perspective, this study supported the hypothesis that maintaining the site as a burial space could point to maintenance of their own funerary practices. Trying to validate this hypothesis, this study used a methodology systematic and ordered to reconstruct the Funerary Profile of site Toca da Baixa dos Caboclos, from the reconstitution of their respective Profiles of Funerary Units. According to this approach it was possible to comment on the funerary practices dispensed to every burial and at the same time, among all burials studied. At the same time, the study of chrono-spatial distribution of burials allowed inferences about the use of internal space of the site at di0erent moments chronological. As a result, recurrences identi&ed were related to funerary practices and also in their own funerary use of internal space of the archeological site. Key words: Prehistory; Funerary practices; Funerary Profile; Toca da Baixa dos Caboclos-PI.
