Efeito do probiótico Bacillus subtilis no crescimento, sobrevivência e fisiologia de rãs-touro (Rana catesbeiana)

The probiotics are live microorganisms, in latency state, that benefices the development of the animals. The objective of this work was to evaluate the effect of the Bacillus subtilis in different doses about the growing, survival and immunological and hematological analyses in the Bullfrog (Rana catesbeiana) froglets. The test was developed in Experimental Frog farm of Agriculture Department, Pindamonhangaba, SP. Three doses of probiotics were tested (T1 - 2.5 g/Kg, T2 - 5 g/Kg and T3 - 10 g/Kg of food). The test was carried out with three simultaneous replicates, plus control group. The products were added to froglet's diet and mixed to the meal. The animals were previously feed with this diet for a period of 14 days and accompanied for about 42 days after metamorphose. Biometrics were performed every 7 days. It was evaluated the final weight, the survival, phagocytic capacity, phagocytic index and hematological analyses as hematocrit, hemoglobin level, erythrocyte number, absolute indices hematimetrycs (MCV and MCHC), differential counting of leucocytes and total counting of leucocytes and trombocytes. The results had shown that the doses of the probiotics had produced none effect on the final weight and survival. The immunological analyses had shown that the probiotics have presented immunostimulator effect, but haven't influenced the hematological parameters of the animals.

Balanço energético comparativo para rotas de escoamento de soja

O presente trabalho objetivou analisar o fluxo energético no escoamento de soja da região Centro-Oeste do Brasil, considerando as rotas atualmente existentes, mais precisamente, do município de Rio Verde -GO até o porto de Santos - SP, visto que este é um grande polo exportador de granéis sólidos. Foram selecionadas duas rotas para a análise, uma contemplando a multimodalidade, ou seja, os modais rodoviário, ferroviário e hidroviário, e outra, uma única modalidade, o modal rodoviário. A conversão dos fatores físicos e operacionais em unidades energéticas foi realizada por meio de coeficientes energéticos levantados junto à literatura. Os resultados obtidos indicaram, pela rota 1 multimodal, um gasto energético específico maior para o modal rodoviário (0,50 MJ km-1 t-1), seguido pelo modal ferroviário (0,42 MJ km-1 t-1) e, em terceiro, o modal hidroviário (0,22 MJ km-1 t-1). Pela rota 2, unimodal rodoviário, o resultado indicou 0,50 MJ km-1 t-1. Nas participações de energia apresentadas, comparando as rotas 1 e 2, a que apresentou maior gasto energético específico total foi a rota 2 (0,50 MJ km-1 t-1), seguida pela rota 1 (0,34 MJ km-1 t-1).

Reguladores vegetais no desenvolvimento e produtividade da cana-de-açúcar

O objetivo deste trabalho foi avaliar o desenvolvimento e a produtividade de colmos de cana-de-açúcar, resultantes da aplicação de reguladores vegetais no iníco da safra. Ostratamentos consistiram na aplicação de três reguladores vegetais inibidores de crescimento - sulfometuron metil, glifosato e compostos de radicais carboxílicos orgânicos + glifosato - e na maturação natural como testemunha, em delineamento experimental em blocos ao acaso, com cinco repetições. Os maturadores retardam o processo de crescimento em altura das plantas, sem afetar o número e o diâmetro de colmos na colheita, e influenciam de forma e intensidade distintas a ocorrência do florescimento e chochamento. O glifosato proporciona elevados índices de brotação lateral e prejudica a rebrota da soqueira. Os maturadores induzem o aumento do teor de açúcares redutores totais, o que contribui para a melhoria da qualidade tecnológica da cana-de-açúcar.

Desenvolvimento e produtividade da cana-de-açúcar após aplicação de reguladores vegetais em meio de safra

The supply of technological quality raw material for providing economical return is the most important necessity of sugar and alcohol industry. The objective of this work was to evaluate the development and productivity of sugarcane stalks due to plant regulators application at half crop. The experiment was carried out in a randomized block design with five replications. The treatments consisted of four plant regulators of the class of the growth retainers (Ethephon, Ehyl-trinexapac, Potassium nitrate, Potassium nitrate + Boron) application and a control (natural ripening). Ethyl-trinexapac and Ethephon treatments were efficient to hold up growth process regarding height of plants, but had no effect on diameter of stalks. The maintenance of bud top integrity made possible the increase in diameter of stalks, without interrupting the growth process regarding height of plants. According to application time the ripeners provided improvement on technological quality of raw material. The ripeners did not affect the number of plants per meter at harvest and did not cause quantitative alterations in the mass of stalks per hectare. The ripeners did not affect the regrowth of the ratoon cane.

A Transposição Didádica dos Gêneros do domínio do discursivo publicitários nos livros didáticos

Advertising text has been a subject of many investigations, because of its multimodal universe. Embodied by a linguistic and discursive materiality laying on scene persuasion, argumentation and power imagery of multissemiotics elements, the advertising text acts as an instrument of power, creating and destroying, promising and denying (CARVALHO, 2007). Advertising not only invites us to act for it, but directs us to look at it. It was under this moving look - of charm and interrogations - that discussions raised in this research were born. Investigations are directed to the school environment, in special, for the discursive advertising domain in Portuguese Language Textbook. It is from this environment that was born our research whose main objective is to analyze how does the didactic transposition of textual genres, described by Marcuschi (2008) as belonging to the "advertising" discourse domain (focusing on advertising genre) in didactic books teaching Portuguese Language before and after the advent of the PCN. Textbooks taken as reference for the study are historically situated in the 90s of the twentieth century and 10 century. Such books refer to elected 7th and 8th grades, currently corresponding to the 8th and 9th grades of elementary school. The choice is justified by the fact that in these Textbook teaching series the presence of advertising domain is recurrent and "didactized". In addition, we are also concerned in analyzing books that circulated around us and our regional reality. Hence, we elected books that were used by two public high schools: Municipal School Clementina Ana da Conceição in Jaçanã city in the Rio Grande do Norte state, State School for Elementary and High school Carlota Barreira in Areia city, Paraíba state. In our research the following categories of analysis were highlighted: (1) presence of advertising in DB, (2) fluctuation terminology: concepts and classifications; (3) The complexity of concepts facilitation, (4) what they propagate, and from which nature are the explored advertisements. From our analysis, we observe how the treatment of textual "advertising" genres have been inserted into Textbooks, and how occurs, in general, their didactic transposition. Focusing on the issue of fluctuating terminology, we noted the difficulty in drawing boundaries between the genres of advertising domain in the Textbooks. However, this also would result in the complexity - in the field of scientific knowledge - of delimiting genres of the same domain. To accomplish our studies, it was required a thorough and systematic dialogue with theories regarding the concept of "Didactic Transposition", due to the theoretical Chevallard Yves (1991), research on the textual genres - Bezerra (2005), Marcuschi (2008), Bazerman (2005), Swales (2004), among others - and studies involving the field of "Advertising" - Sandmann (2002), Carvalho (2007) and others

Letramento no trânsito: eventos e práticas na formação de condutores de veículos

In the contemporary society, the language is presented in all social spaces and assumes many different purposes in order to meet the needs that emerge from each of these sphere. In traffic, this reality is not different. To guide vehicles, it is necessary to know, by means of reading artifacts, what the legislation establishes in what concerns the way to act in this domain. Thus, this works aims at describing the practices of literacy held in events of driver trainings and know the expectations generated by drivers/learners from this training. In theoretical terms, it anchors in Literacy Studies, comprehended here as social practices (BARTON; HAMILTON, 1998; KLEIMAN, 1995, 2008; MORTATTI, 2004; STREET, 1984; OLIVEIRA, 2008, 2010; ROJO, 2009; PAZ, 2008). Genre Theory (BRONCKART, 2004, 1999; OLIVEIRA, 2010) and in your multimodal instance (KRESS; VAN LEEUWEN, 1996; DIONÍSIO, 2006). In terms of methodology, it follows the bias of qualitative research, because of its ethnographic nature (BOGDAN; BIKLEN, 1994; MINAYO, 2010; CANÇADO, 1994; CHIZZOTTI, 2005). The research corpus was generated by reading the Brazilian Traffic Code, by observing the literacy events held in Drivers Training Centers of Natal, analysis of course books used in these events, plus questionnaires with open and closed questions and semistructured interviews. The collaborators are constituted of drivers in training, and instructors who work in this field. The analyses show significant contributions regarding the placement more committed of future drivers with the welfare and safety of those who use the public roads, from the practice or reading done during the traffic training. The contribution of this work lies in the possibility to expand the discussion about the language practice uses regarding the training for the traffic, more specifically, the training of drivers of vehicles

O desenvolvimento da interlíngua na aprendizagem da escrita em inglês em uma escola bilíngue: um estudo exploratório

The aim of this study is to investigate the development of written Interlanguage in English as an Additional Language (AL) by students in the 2nd grade of Ensino Fundamental I in a bilingual school in the city of Natal-RN. For this purpose two research questions guided this study: (a) which hypotheses could be inferred from the writing development of the bilingual learners of English as AL? and, (b) what is the impact of the type of input monomodal or multimodal in the Interlanguage development in the AL of bilingual learners? The 38 learners were divided into a control group, with 21 learners exposed to monomodal input, and an experimental group, with 17 learners exposed to multimodal input, and pre and post-tests were applied to both groups. A mixed methods research design was conducted (DÖRNYEI, 2007) to involve both qualitative and quantitative data collection and analysis. The qualitative aspect comprehended descriptive characteristics that interpreted the central cognitive processes in the acquisition of writing in AL by the learners. Through these interpretations, it was possible to understand the constitution of written Interlanguage (SELINKER, 1972) according to the data generated by the learners. The quantitative data were presented as the results generated from the experimental design. Thus, they narrowed the relations between the dependent variable the writing development, that is, how close it is to the target form which was modified throughout the process by the independent variable the quality of input (VAN PATTEN, 2002, GASS, 1997, SCHMIDT, 1986, PARADIS, 2009; 2010, ELLIS, 1995), which, being monomodal or multimodal, its function was possibly to alter the route of acquisition. The quantitative results pointed towards significant gains by the experimental group, which had multimodality present, suggesting that the learners in this group seem to have been more able to cognitively register (SCHIMDT, 1990) aspects of learning than the learners in the control group

O ensaio jornalístico na revista Veja: uma análise multidimensional

This work has as objective generality to make a multidimensional analysis in the genre journalistic assay, communicative genre that, beyond complex and multimodal, presents hybrid characteristics. Specifically, with the intention to propose defining criteria of the cited genre, this research looks for to establish differences and similarities between the assay and other genres of the same sphere, from the description and interpretation of used multimodal resources. The analysis of the formal, schematical and rhetorical resources identified in the formatting of the journalistic assay sample that the analyses are supported in the socio-semiotic and socio-rhetorical approaches. In the formal dimension, we contemplate elements that constitute design of the text, including the forms of representation from the typography, the colors, images, as well as the aspects communicative-linguistics: the modalization indices, the communicative operators and the category time; in the schematical dimension, we present the organizational structure, considering the rhetorical movements postulates for Swales (1990) and in the rhetorical dimension we observe the categories: who writes, for who it writes, on what it writes and where writes. The adopted methodologicals postulates are of qualitative nature and the procedure is documentary, data that in we are valid them written texts of this genre as analysis object. Corpus it is constituted by a composed sample for 14 extracted texts of a set of 173 propagated journalistic assays weekly for the magazine Veja, in the period between August of 2004 and January of 2008. The analysis of the data showed that the journalistic assay, object of this study, materializes through multiple symbolic representations and multiple subjects that turn since a small episode of the daily facts of great social relevance in the present time, of historical and cultural nature, nationwide or international. Used for the first time by Montaigne in 1580, to assign, in saying of the proper author, written fast on its life and historical events, which could nor be remembered later , the term `assay' was enriched with other specifications, of form to enclose the one that if they call scientific assay today, academic assay, journalistic assay and other types of specific assays. These denominations have to see with the enrollment of the members of diverse of practices communities, in virtue of the multiplicity of activities carried through in these spheres. The conclusions the one that we arrive had been the following ones: 1. the discursive genre is not a pure entity, in virtue of the multiplicity of situations where the sorts if insert in the social actions; 2. the institutions define the configuration of one definitive genre, also its proper assignment, since for backwards of all discursive genre a voice exists to discipline - institutional voice, and in the case of the assays for analyzed us, the institutional voice if it presents, really, as a defining trace; 3. the journalistic assay, for its multiple symbolic representations, multiple subjects and for passing explicit or implicit opinions of its author, resembles it other genres, being able, therefore, to be inserted in a colony of opinionatives genres

Post-operative analgesic effects of butorphanol or firocoxib administered to dogs undergoing elective ovariohysterectomy

ObjectiveTo compare the post-operative analgesic effects of butorphanol or firocoxib in dogs undergoing ovariohysterectomy.Study designProspective, randomized, blinded, clinical trial.AnimalsTwenty-five dogs > 1 year of age.MethodsDogs received acepromazine intramuscularly (IM), 0.05 mg kg-1 and either butorphanol IM, 0.2 mg kg-1 (BG, n = 12) or firocoxib orally (PO), 5 mg kg-1 (FG, n = 13), approximately 30 minutes before induction of anesthesia with propofol. Anesthesia was maintained with isoflurane. Ovariohysterectomy was performed by the same surgeon. Pain scores using the dynamic and interactive visual analog scale (DIVAS) were performed before and at 1, 2, 3, 4, 6, 8 and 20 hours after the end of surgery by one observer, blinded to the treatment. Rescue analgesia was provided with morphine (0.5 mg kg-1) IM and firocoxib, 5 mg kg-1 (BG only) PO if DIVAS > 50. Groups were compared using paired t-tests and Fisher's exact test (p < 0.05). Data are presented as mean +/- SD.ResultsThe BG required significantly less propofol (BG: 2.6 +/- 0.59 mg kg-1; FG: 5.39 +/- 0.7 mg kg-1) (p < 0.05) but the anesthesia time was longer (BG: 14 +/- 6, FG: 10 +/- 4 minutes). There were no differences for body weight (BG: 7.9 +/- 5.0, FG: 11.5 +/- 4.6 kg), sedation scores, and surgery and extubation times (BG: 10 +/- 2, 8 +/- 5 minutes; FG: 9 +/- 3, 8 +/- 4 minutes, respectively) (p > 0.05). The FG had significantly lower pain scores than the BG at 1, 2 and 3 hours following surgery (p < 0.05). Rescue analgesia was administered to 11/12 (92%) and 2/13 (15%) dogs in the BG and FG, respectively (p < 0.05).Conclusion and clinical relevanceFirocoxib produced better post-operative analgesia than butorphanol. Firocoxib may be used as part of a multimodal analgesia protocol but may not be effective as a sole analgesic.

Analgesic efficacy of perioperative use of vedaprofen, tramadol or their combination in cats undergoing ovariohysterectomy

The analgesic efficacy of tramadol and/or vedaprofen was evaluated in cats submitted for elective ovariohysterectomy, using a randomised double blind placebo controlled design. Forty adult female cats (3.0 +/- 0.32 kg; 1.8 +/- 0.7 years) were distributed into four groups. Vedaprofen PO (0.5 mg/kg), tramadol SC (2 mg/kg), both, or placebo was administered 1 h before surgery and every 24 and 8 h, respectively, for 72 h after surgery. Pain score evaluated by interactive visual analogue and composite pain score and hyperalgesia by the von Frey filament test were recorded at 1, 2, 4, 6, 8, 12, 24, 28, 32, 48, 52, 56, 72, 96 h and on the 7th day after surgery. Animals treated with combined vedaprofen and tramadol treatment did not need rescue analgesia, did not develop hyperalgesia, and their serum cortisol concentrations and pain scores were lower than placebo until 24 and 72 h after surgery, respectively. Combined vedaprofen and tramadol treatment provided more effective postoperative analgesia and prevented hyperalgesia than when used on their own. Multimodal technique is a superior method of treating pain after feline ovariohysterectomy. This work also provides evidence for the benefits of analgesia for up to 3 days following ovariohysterectomy. (C) 2008 ESFM and AAFP. Published by Elsevier Ltd. All rights reserved.

Tests of proportional hazards and proportional odds models for grouped survival data

In this paper, we derive score test statistics to discriminate between proportional hazards and proportional odds models for grouped survival data. These models are embedded within a power family transformation in order to obtain the score tests. In simple cases, some small-sample results are obtained for the score statistics using Monte Carlo simulations. Score statistics have distributions well approximated by the chi-squared distribution. Real examples illustrate the proposed tests.

Biology and shell relationship in Clibanarius vittatus (Bosc, 1802) (Crustacea, Diogenidae) from Sao Vicente, SP, Brasil.

This study aimed to characterize the populational structure of Clibanarius vittatus (Bosc, 1802), as well as to determine the morphometric relations between the animal's size and the variables: length of their chelar propodus and the size of the shell opening. C. vittatus is a relatively abundant pagurid on the west Atlantic coast, it occurs in the intertidal region from 38 degrees N to 28 degrees S. The animals in this study were randomly sampled every month on the Paranapu (a) over tilde Beach (46 degrees 23' S e 23 degrees 59' W), S (a) over tilde $ o Vicente (SP), Brazil. The biometrics data were adjusted to the power equation (y = ax(b)), by means of the minimum square method. A total of 427 individuals were collected. The size of the cephalothoraxic shield ranged from 2.5 to 12.7 mm, evidencing a representative sample of the population. The of most commonly genus of Gastropoda shells occupied by the hermits was Thais (97,26%). In relation to the morphometric analyses performed, it was observed a positive correlation between the animal size and the variables length of the chelar propodus and the size of the shells.
