ABSTRACT Pregnancy toxemia has a high mortality rate and few cases with effective treatment are reported, especially when associated with secondary diseases. Therefore, the present work reports the case of a sheep, which was referred to the veterinary hospital of UFMG, in the last month of pregnancy, presenting apathy, hyporexia and sternal recumbency. After the diagnosis of pregnancy toxemia, the fetuses were removed while still alive, but did not survive. Monitoring was started with blood gas analysis, blood glucose assessments and laboratory tests. The results were consistent with liver damage, which was justified by the condition of lipolysis. Treatment consisted of electrolyte replacement plus 50% glucose and potassium chloride, along with administration of antibiotics (ceftiofur, 5mg/kg/SID/IM/7 days), flunixim meglumine (2.2mg/kg/SID/IM first day and 1.1mg/kg/SID/IM on the second and third days) and omeprazole (4mg/kg/SID/oral). The patient had secondarily clinical laminitis, which was treated with cryotherapy and anti-inflammatory drugs, in addition to mastitis, using a single dose of intramammary antibiotics. The work demonstrated the effectiveness of the treatment of pregnancy toxemia, when performed early and intensively, associated with daily clinical and laboratory monitoring of the animal.

RESUMO A toxemia da prenhez possui alto índice de mortalidade, e poucos casos com tratamento eficaz são relatados, principalmente quando associados a doenças secundárias. Diante disso, o presente trabalho relata o caso de uma ovelha, que foi encaminhada ao hospital veterinário da UFMG, no último mês de gestação, apresentando apatia, hiporexia e decúbito esternal. Após o diagnóstico de toxemia da prenhez, os fetos foram retirados ainda vivos, porém não sobreviveram. Iniciou-se um monitoramento com análises hemogasométricas, avaliações de glicemia e exames laboratoriais. Os resultados foram condizentes com lesão hepática, a qual foi justificada pelo quadro de lipólise. O tratamento consistiu em reposição hidroeletrolítica associada à glicose 50% e a cloreto de potássio, juntamente com administração de antibióticos (ceftiofur, 5mg/kg/SID/IM/7 dias), flunixim meglumine (2,2mg/kg/SID/IM no primeiro dia e 1,1mg/kg/SID/IM no segundo e terceiro dias) e omeprazol (4mg/kg/SID/oral). A paciente apresentou secundariamente laminite clínica, a qual foi tratada com crioterapia e antinflamatórios, além de um quadro de mastite, sendo utilizado antibiótico intramamário em dose única. O trabalho demonstrou a eficácia do tratamento da toxemia da prenhez, quando realizado de forma precoce e intensiva, associado a um monitoramento clínico e laboratorial diário do animal.

Abstract The study was carried out on an agroecological property located in Cologne São Manoel, 8th district of Pelotas, RS, Brazil. Anochetus neglectus Emery, 1894 was collected in an area of peach orchard that has been under an agroecological system for 18 years. This record expands the area of occurrence and distribution of this rare species in the Neotropical Region.

ABSTRACT The objective of this study was to evaluate changes in the biochemical parameters of feedlot lambs fed with high concentrations of crude glycerin (GC). Forty crossbred lambs (Dorper × Santa Inês), non-castrated, weighing 21.7±2.7kg and 90 days old, were randomly assigned to four treatments (0, 10, 20, and 30% GC in the diet). To evaluate the biochemical parameters, blood samples (pre-prandial and 4 h after morning feeding) were collected on the first day and the day before slaughter, in each treatment. The high-density lipoprotein was linearly decreased (P<0.0001) when GC concentrations were increased in the diet. Alkaline phosphatase was quadratically affected by treatments (P=0.05), with greater values observed in blood from animals fed intermediate concentrations of CG, and gamma-glutamyl transferase was linearly increased (P=0.008). The blood urea was quadratically affected by treatments with lower values observed in blood from animals fed intermediate concentrations of CG. In conclusion, the replacement of up to 30% (based on dry matter) of corn grain by crude glycerin, in diets for feedlot finishing lambs, does not compromise the health status of these animals.

RESUMO O objetivo deste estudo foi avaliar as alterações nos parâmetros bioquímicos de cordeiros confinados, alimentados com elevadas concentrações de glicerina bruta (GC). Quarenta cordeiros mestiços (Dorper × Santa Inês), não castrados, com 21,7±2,7kg de peso e 90 dias de idade, foram distribuídos aleatoriamente em quatro tratamentos (0, 10, 20 e 30% de GC na dieta). Para avaliar os parâmetros bioquímicos, amostras de sangue (pré-prandial e 4h após a alimentação matinal) foram coletadas no primeiro dia e no dia anterior ao abate, em cada tratamento. A lipoproteína de alta densidade no sangue diminuiu linearmente (P<0,0001) quando as concentrações de GC foram aumentadas. A fosfatase alcalina foi afetada quadraticamente pelos tratamentos (P=0,05), com valores maiores observados no sangue de animais alimentados com concentrações intermediárias de GC, e a gamaglutamiltransferase aumentou linearmente (P=0,008). A ureia sanguínea foi afetada de forma quadrática pelos tratamentos, com valores menores observados no sangue de animais alimentados com concentrações intermediárias de GC. Em conclusão, a substituição de até 30% (com base na matéria seca) do grão de milho por glicerina bruta, em dietas para cordeiros em terminação em confinamento, não compromete o estado de saúde desses animais.

RESUMO Objetivou-se, com este estudo, encontrar níveis adequados de inclusão de butirato de sódio em ração pós-eclosão e pré-inicial, buscando minimizar os efeitos negativos do jejum de pintos de corte. Os animais foram distribuídos em delineamento inteiramente ao acaso, com cinco tratamentos e cinco repetições de 10 aves cada. Foram utilizadas cinco suplementações de butirato de sódio (controle; 0,05; 0,075; 0,100 e 0,200%) na ração pré-inicial, fornecidas aos pintos na caixa de transporte e durante a fase pré-inicial. Após 24 horas de acesso ao alimento e aos sete dias de idade, foram avaliados desempenho, retração do saco vitelino, concentração de glicose plasmática, peso e histomorfometria do intestino delgado. De sete a 10 dias de idade, realizou-se ensaio de metabolizabilidade. A suplementação de 0,10% de butirato de sódio aumentou o desenvolvimento das vilosidades intestinais dos pintos de corte aos sete dias de idade, mas não foi capaz de melhorar o desempenho na fase pré-inicial. A suplementação com butirato de sódio em dieta oferecida na caixa de transporte não melhora o desempenho dos frangos na fase pré-inicial. Recomenda-se suplementação de até 0,16%, a fim de melhorar a metabolizabilidade do extrato etéreo para frangos de corte aos sete dias de idade.

ABSTRACT This study was designed to determine adequate levels for sodium butyrate inclusion in pre-hatching and pre-starter feed in order to minimize the negative effects of post-hatch delayed placement on broiler chicks. Newly-hatched chicks were allotted in a completely randomized design, with five treatments, each comprising five replicates of ten birds each. Five dietetic levels of sodium butyrate (control, 0.050, 0.075, 0.100 and 0.200%) were used in the pre-starter feed offered to the chicks in the transporting box and during the pre-starter phase. Performance, yolk sac retraction, plasma glucose concentration, weight and histomorphometry of the small intestine were evaluated after 24 hours of feed access and at 7 days of age. A metabolic trial was performed when the chicks were seven to ten days of age. Supplementation of 0.1% sodium butyrate increased the development of broiler chicks’ intestinal villi at seven days of age but was not able to improve performance in the pre-starter phase. Supplementation with sodium butyrate in a diet offered in the transportation box does not improve broiler performance in the pre-starter phase. Supplementation of up to 0.16% is recommended, in order to improve the metabolizability of the ether extract for broilers at seven days of age.

Abstract The objective of the study was to compare the richness and diversity of ant assemblages in an agroecological system under peach orchard, conventional system under peach orchard cultivation and native vegetation in rural properties located in a Pampa Biome. The study was conducted in four samplings in 2017: 1st and 09th March (summer); 24th and 31st July (winter); and four samplings in 2018: 23rd and 30th January (summer); 31st July and 07th August (winter). Pitfall traps were used. The assemblages were characterized and compared using richness, number of occurrences of ants, Shannon diversity (H’), equitability, rarefaction analysis and Chao 1. The association of the species with the samples was evaluated by a Principal Component Analysis (PCA). The agroecological system had the highest number of occurrences, while the conventional orchard the lowest number. Richness and abundance were greatest during the summer. The conventional peach orchard obtained the lowest H’ for both seasons when compared to the agroecological orchard and native vegetation. The PCA explained 77.40% of the occurrence of ants in the environments and in the seasons. The results found demonstrated that conservationist systems tend to harbor greater wealth and diversity of ant assemblages, as well as occurring in native áreas.

RESUMO O uso de anestésicos em pisciculturas é indispensável para reduzir o estresse durante o manejo. O presente trabalho propôs avaliar o efeito do eugenol como anestésico para manejo do curimatã (Prochilodus nigricans). Foram utilizados 50 espécimes (221,34±9,0 g; 25,8 ±1,1 cm), submetidos a cinco tratamentos com concentrações de 0, 25, 50, 100 e 200 mg L−1 de eugenol em exposição de 10 minutos. Foram registrados os tempos necessários para atingir cada estágio anestésico e a recuperação de cada peixe. Para verificação dos níveis de glicose sanguínea, foram realizadas coletas individuais de sangue dos peixes antes da imersão e após os 10 minutos de exposição ao anestésico. A avaliação do efeito do anestésico sobre as brânquias foi realizada por meio de análises histopatológicas. A concentração de 50 mg L−1 ficou dentro do limite ideal de três minutos preconizado para indução à anestesia cirúrgica e não elevou significativamente os níveis de glicose quando comparada ao grupo controle (35,7±19,4 mg dL−1), além de não provocar lesões branquiais. Nessa concentração, os peixes apresentaram níveis de glicose sanguínea controlada, dentro dos teores basais, além de não correrem o risco de apresentarem problemas posteriores em relação à mortalidade, pois essa concentração garante a boa saúde das brânquias e uma boa recuperação dos animais.

ABSTRACT The use of anesthetics in fish farming is essential to reduce stress during management. The present study proposes to evaluate the effect of eugenol as an anesthetic for the management of curimatã (Prochilodus nigricans). Fifty specimens were used (221.34±9.0 g; 25.8 ±1.1 cm), submitted to five treatments with concentrations of 0, 25, 50, 100 and 200 mgL−1 eugenol for 10 min. The times required to reach each anesthetic stage and the recovery of each fish were recorded. To check bloodglucose levels individual blood samples were taken from the fish before immersion and after ten minutes of anesthetic exposure. Evaluation of the anesthetic effect ongills was performed by histopathological analysis. The concentration of 50 mgL−1 was within the ideal limit of three minutes recommended for surgical anesthesia induction and did not significantly increase glucose levels when compared to the control group (35.7±19.4 mg dL−1), besides not causing gill injuries. At this concentration the fish presented controlled blood glucose levels within the basal levels, besides not taking the risk to have later problems concernig mortality, because this concentration ensures the good health of the gills and good recovery of the animals.

RESUMO Devido à ausência de estudos sobre capivaras na região Nordeste do Brasil, o objetivo deste estudo foi avaliar a sanidade desses roedores de vida livre em três áreas dos biomas Mata Atlântica (2) e Caatinga (1) do estado de Pernambuco, por meio da determinação de parâmetros da hematologia e bioquímica sérica. De novembro de 2016 a dezembro de 2017, foram capturados 21 animais, dos quais foram coletadas amostras de sangue para avaliação hematológica (eritrograma, leucograma e plaquetometria) e bioquímica sérica (atividade enzimática, perfil proteico, energético e mineral). A maioria dos parâmetros esteve dentro dos valores de normalidade para a espécie, embora alguns apresentassem diferenças estatisticamente significativas de acordo com a área de estudo (hemoglobina, hematócrito, VCM, CHCM, eosinófilos, fosfatase alcalina, proteína total, albumina, ácido úrico, creatinina, lactato, sódio e magnésio) e o sexo dos animais (ácido úrico). Os parâmetros obtidos são apresentados como referência e atestam a sanidade e o bom estado nutricional de populações de capivaras nos biomas Mata Atlântica e Caatinga da região Nordeste do Brasil. As informações aportadas neste estudo pioneiro na região Nordeste contribuem para aumentar o conhecimento sobre a ecofisiologia e a conservação in situ de capivaras.

ABSTRACT Due to the lack of studies about capybaras in the northeast region of Brazil, the objective of this study was to evaluate the health status of free-ranging capybaras in three areas of Atlantic Forest (2) and Caatinga (1) biomes in Pernambuco state, through the determination of hematological and serum biochemical parameters. From November 2016 to December 2017, 21 animals were captured and blood samples were collected for the hematological (erythrogram, leukogram and platelet counts) and serum biochemistry (enzymatic activity, protein, energy and mineral profile) evaluation. Hematological and serum biochemical parameters were within the normal range for the species, but some presented statistically significant variations according to the study area (hemoglobin, hematocrit, MCV, MCHC, eosinophils count, alkaline phosphatase, total proteins, albumin, uric acid, creatinine, lactate, sodium and magnesium) and sex of the animals (uric acid). The parameters obtained are presented as reference and attest to the health and good nutritional status of populations of capybaras in the Atlantic Forest and Caatinga biomes of northeastern Brazil. The information provided in this pioneering study in the northeast region contributes to increased knowledge about the ecophysiology and in situ conservation of capybaras.

RESUMO São descritos casos de síndrome de compressão medular, associada a granulomas pós-vacinais, em bovinos Nelore, provenientes de uma propriedade em Minas Gerais. Esses bovinos apresentavam ataxia e paresia bilateral dos membros pélvicos, que evoluiu para paralisia e decúbito esternal. Na necropsia, áreas focalmente extensas da musculatura na região torácica dorsal (músculo longissimus dorsi) eram substituídas por numerosos piogranulomas, separados por tecido brancacento e firme (tecido conjuntivo fibroso). Ao corte, alguns nódulos continham material amarelado e viscoso (exsudato purulento) ou material esbranquiçado e fluido (sugestivo de adjuvante de vacina). No canal medular das vértebras subjacentes, havia granulomas idênticos aos observados no tecido muscular. Histologicamente, os piogranulomas continham, no centro, vacúolo, bem delimitado e arredondado (consistente com o espaço deixado pela gotícula de lipídio do adjuvante), circundado por variável quantidade de neutrófilos degenerados e íntegros e, mais externamente, por numerosos macrófagos epitelioides e algumas células gigantes multinucleadas. Nas áreas da medula espinhal, circundadas pelos granulomas, numerosos vacúolos, bem definidos, eram observados na substância branca (degeneração walleriana). A associação do histórico clínico e de achados patológicos permitiu o diagnóstico de mielopatia compressiva associada à reação granulomatosa ao adjuvante oleoso da vacina contra febre aftosa, no caso, induzida pela aplicação inadequada da vacina.

ABSTRACT Cases of compressive myelopathy syndrome associated with post vaccinal pyogranulomas were diagnosed post mortem in three cows from a farm in Minas Gerais state, Brazil. These cows presented ataxia and bilateral paresis of the pelvic limbs, which evolved to paralysis, and sternal recumbence. On necropsy, locally extensive areas of the longissimus dorsi muscle were replaced by pyogranulomas supported by moderate amounts of fibrous connective tissue. On the cut surface, some nodules contained yellowish and viscous fluid (purulent exudate) or whitish fluid (interpreted as the oily adjuvant of a vaccine). In the spinal canal of the subjacent vertebrae, compressing the spinal cord, were pyogranulomas identical to those described in the skeletal muscle. Histologically, the pyogranulomas were composed of a central clear vacuole (consistent with the space left by the oil adjuvant droplets), surrounded by neutrophils and, more externally, by large numbers of epithelioid macrophages and fewer multinucleated giant cells. In the white matter of the spinal cord were numerous well-defined, clear vacuoles (Wallerian degeneration). The association of the clinical history and pathological findings allowed the diagnosis of compressive myelopathy associated with pyogranulomatous reaction to the oily adjuvant of the foot-and-mouth disease vaccine, in this case, due to its inadequate application.

Abstract Natural products are a major source of drugs for the treatment of cancer. The species Alpinia zerumbet (Pers.) B.L. Burtt & R.M. Sm, Zingiberaceae, is widely distributed in Brazil where it is known as “colônia”. The leaves are commonly used in the treatment of hypertension and dyspepsia, however, the effects of A. zerumbet extracts and isolated substances on human cancer cells remain to be elucidated. This study was designed to identify the chemical constituents of hydroalcoholic and dichloromethane extracts from A. zerumbet leaves and to investigate their in vitro antiproliferative activity. The isolated phytochemicals included kaempferol, dihydro-5,6-dehydrokavain, 5,6-dehydrokavain, and pinostrobin. The hydroalcoholic extract inhibited cellular proliferation only at high concentrations, while the dichloromethane extract showed a moderate antiproliferative effect against leukemia and lung tumor cell lines. 5,6-Dehydrokavain showed potent cytostatic activity against glioblastoma cells and a moderate effect on all other tumor cell lines. Pinostrobin showed potent activity against leukemia and breast tumor cell lines and moderate cytostatic effect against ovarian cell. Furthermore, this is the first report on the isolation of kaempferol and pinostrobin from A. zerumbet leaves. Moreover, the purification process described in this study was effective. These results suggest that A. zerumbet leaves are a promising source of anticancer compounds.

RESUMO O período de transição é uma fase de grandes desafios para vacas leiteiras, e desequilíbrios minerais são frequentes. O objetivo ao desenvolver este trabalho foi de entender melhor o perfil mineral de vacas leiteiras F1 Holandês x Gir e suas performances sob as diferentes condições de verão e inverno. Para isso, foram mensurados cálcio, magnésio e fósforo sanguíneo. As coletas de sangue foram realizadas durante os períodos de verão e inverno, e utilizaram-se, respectivamente, 15 e 13 vacas leiteiras pluríparas, todas F1 Holandês x Gir. As coletas de sangue começaram quatro semanas antes da data prevista do parto até 30 dias pós-parto. As concentrações médias e o padrão de variação dos três minerais foram distintos em cada estação do ano, representando a interação tempo de coleta x estação do ano. A concentração de cálcio foi menor no inverno, período em que todos os animais apresentaram hipocalcemia subclínica, enquanto no verão 38,46% apresentaram essa condição. A concentração de magnésio foi maior no verão e nenhum animal teve hipomagnesemia, enquanto no inverno 46,67% dos animais apresentaram hipomagnesemia subclínica, contribuindo para a maior frequência de hipocalcemia observada no inverno. Uma alta proporção de animais teve hiperfosfatemia, o que pode representar um problema ambiental. A alta frequência de animais com hipocalcemia subclínica é alarmante principalmente devido às consequências geradas por essa condição.

ABSTRACT The transition period is often a great challenge for dairy cows and mineral imbalances are frequent. With the aim to better understand the mineral profile of F1 Holstein x Gyr dairy cows and their performances under the different conditions of summer and winter, we collected blood samples to measure calcium, magnesium and phosphorus. Samplings were performed during summer and winter, on 15 and 13 pluriparous F1 Holstein x Gyr dairy cows, respectively. Blood sampling started 4 weeks prior to the expected calving date until 30 days postpartum. The mean concentrations of all three minerals had a different pattern during the transition period in each season, representing the interaction time x season. Calcium concentration was lower in winter and more animals suffered from subclinical hypocalcemia (100%) then in summer (38.46%). Magnesium concentration was also lower in winter and 46.67% of animals had hypomagnesemia, contributing for the higher hypocalcemia frequency observed in the same season. A high proportion of animals had hyperphosphatemia what can represent an environmental problem and more attention should be given to it. The high frequency of animals with subclinical hypocalcemia is alarming once that can lead to greater consequences.

Abstract Purpose: To investigate the cellular response to injury, analyzing histopathologic changes associated with increased cellularity, degeneration and disorganization of collagen fibers. Methods: Thirty wistar rats were divided in two groups after partial Achilles tenotomy: the right hind paw were treated with the essential oil of Alpinia zerumbet (EOAz), diluted to 33% (0.3 mL kg-1), and the left hind paw received sunflower oil for 3, 14, 30 and 90 days. Statistical significance was determined using a Chi-square and Pearson Correlation qualitative variables test. Moreover, Mann-Whitney U-test test for comparison between different groups of the same cell, one-way ANOVA, and Tukey’s test of quantitative measurement. Results: A decrease hyperemia (p < 0.001) was observed in the acute phase of inflammatory cell number (p < 0.001), whereas sub-acute phase was marked by significant correlation with macrophages in fibroblasts (r = 0.17, p = 0.03), with probable induction a dense and modeled tissue. At chronic phase, it was found an increase in the number of fibroblasts and a higher percentage of type I collagen fibers (78%) compared with control collagen fibers (55%). Conclusion: Oil of Alpinia zerumbet stimulated the process of maturation, organization and tissue repair which gave it greater resistance.

RESUMO Objetivou-se com este trabalho relatar os achados histopatológicos em pulmões de Eretmochelys imbricata provenientes dos litorais dos estados do Espírito Santo e do Rio de Janeiro, Brasil. Amostras de pulmões de 29 E. imbricata foram coletadas, durante os anos de 2010 a 2014, em necropsias de espécimes encalhadas mortas ou que vieram a óbito durante o tratamento, nos litorais dos estados do Espírito Santo e do Rio de Janeiro, fixadas em formalina tamponada neutra a 10%, submetidas ao processamento histológico de rotina e classificadas histomorfologicamente. Os dados dos animais mostraram que 37,93% dos animais apresentaram lesões pulmonares. Destes, 90,91% foram encontrados vivos e 9,09% morto, 63,63% eram fêmeas e 36,37% machos. O peso médio foi de 5,44kg, e o comprimento médio de 39cm, o que caracterizou animais juvenis. Os animais eram provenientes de São Francisco de Itabapoana - RJ, Aracruz - ES, São Mateus - ES, Guarapari - ES, Linhares - ES, Itapemirim - ES e Anchieta - - ES. Á macroscopia, observou-se: presença de espuma, hiperemia, nódulos no parênquima, cisto e cáseo. Ao exame microscópico, foram encontrados broncopneumonia heterofílica, pneumonia granulomatosa parasitária, causadas por espirorquídeos, pneumonia granulomatosa bacteriana, pneumonia granulomatosa fúngica e congestão. Conclui-se que exemplares juvenis de Eretmochelys imbricata, fêmeas e machos, provenientes dos estados do Espírito Santo e do Rio de Janeiro e encalhados tanto vivos quanto mortos, apresentam lesões pulmonares importantes, principalmente as de origem inflamatória, associadas ou não a agentes infecciosos.

ABSTRACT The present work aimed to report the histopathological findings verified in lungs of hawksbill turtles (Eretmochelys imbricata) retrieved from the coasts of the states of Espírito Santo and Rio de Janeiro, Brazil. Between the years 2010 and 2014, 29 E. imbricata individuals were found stranded on the coasts, already dead or dying during treatment. Lung samples of all specimens were collected during necropsies, fixed in 10% neutral buffered formalin, subjected to routine histological processing and classified histomorphologically. The findings revealed that 37.93% of the specimens presented lung lesions. Of these, 90.91% were rescued alive and 9.09% were found dead; 63.63% were females and 36.37% were males. The mean weight was 5.44 Kg and the mean length 39 cm, characterizing young individuals. The animals originated from São Francisco de Itabapoana - RJ, Aracruz - ES, São Mateus - ES, Guarapari - ES, Linhares - ES, Itapemirim - ES, and Anchieta - ES. Macroscopic analysis revealed presence of foam, hyperemia, nodules in the parenchyma, cyst and caseous material. Microscopic examination evidenced heterophilic bronchopneumonia, parasitic granulomatous pneumonia caused by spirorchiids, bacterial granulomatous pneumonia, fungal granulomatous pneumonia, and congestion. It was concluded that juvenile specimens of Eretmochelys imbricata, females and males, originated from the states of Espírito Santo and Rio de Janeiro and found stranded both alive or dead, have significant lung lesions, mainly inflammatory ones, associated or not with infectious agents.

The first part of this article argues that descriptivism as proposed by Moritz Schlick does not correctly understand the function of moral judgements. The second part argues that emotivism does not provide an adequate explanation of the role of reason in ethics. Finally, the article shows how the universal prescriptivism proposed by R. M. Hare furthers the solution of the problems of emotivism, since it extends the role of reason in ethics and in the resolution of the problems of descriptivism, given that it understands the function of moral judgements in ordinary language.

Na primeira parte, argumento que o descritivismo proposto por Moritz Schlick não compreende adequadamente a função dos juízos morais. Na segunda parte, argumento que o emotivismo não apresenta uma explicação adequada para o papel da razão na ética. Na terceira parte, argumento que o prescritivismo universal proposto por R. M. Hare avança na solução dos problemas do emotivismo, porque amplia o papel da razão na ética, e na solução dos problemas do descritivismo, porque compreende a função dos juízos morais na linguagem ordinária.

Cellular production is usually seen as a hybrid approach between job-shop and flow-line paradigms, reducing the major disadvantages of these two paradigms: the low productivity of job-shops and the low flexibility (in terms of products' variety) of the flow-lines. This paper describes the implementation of a production cell in a production unit of wood-framed pictures and mirrors, which was originally configured as a traditional job-shop, without losing the necessary flexibility to face market demand and simultaneously increasing the production unit's performance. By implementing a highly flexible cell, very significant improvements were expected for the system's overall performance and the quality of the products. These expectations were met, and the implementation was successful, as demonstrated by the results presented.

Sellulêre produksie word gewoonlik gesien as 'n kombinasie van werkswinkel en vloeilyn benaderings en in die proses word die groot nadele van beide die benaderings, naamlik die lae produktiwiteit van werkswinkels en die lae aanpasbaarheid (in terme van produk variëteit) van vloeilyne, verminder. Die implementering van 'n produksie sel in 'n houtraamvervaardigingsaanleg, wat aanvanklik as 'n tradisionele werkswinkel uitgelê is, word beskryf. Hierdie implementering vind plaas sonder om die aanleg se aanpasbaarheid te beïnvloed terwyl die produktiwiteit verhoog word. Deur 'n hoogs aanpasbare produksie sel te implementeer word noemenswaardige verbeteringe in die sisteem se algehele verrigting en gehalte verwag. Hierdie verwagtinge is inderdaad bereik en die implementering is dus as suksesvol beskou.

Objetivou-se neste trabalho avaliar o efeito de diferentes formulações à base de glyphosate sobre a colonização micorrízica e nodulação no cultivar de soja RR TMG 125. Os experimentos foram desenvolvidos em condições de campo, em Latossolo Vermelho-Amarelo, durante os anos agrícolas 2010/2011 e 2011/2012. Os tratamentos constaram da aplicação da dose de 720 g e.a. ha-1 das seguintes formulações de glyphosate: Trop®, Roundup Original®, Roundup Ultra®, Roundup WG®, Roundup Transorb R® e Zapp Qi®, além de duas testemunhas (capinada e não capinada). Utilizou-se o delineamento em blocos casualizados com quatro repetições. A matéria seca da parte aérea, nodulação e produtividade de soja não foram influenciadas pelas diferentes formulações de glyphosate. Para a colonização micorrízica, observou-se efeito positivo da formulação Roundup Original®, em relação à testemunha capinada; no entanto, esse efeito não foi contínuo nos dois anos de experimento. A variável número de nódulos foi mais afetada pelas formulações de glyphosate testadas.

The aim of this study was to evaluate the effect of different glyphosate-based formulations on mycorrhizal colonization and nodulation in soybean cultivar RR TMG 125. The experiments were conducted under field conditions in Red-Yellow Latosol, during 2010/2011 and 2011/2012. The formulations Trop®, Roundup Original®, Roundup Ultra®, Roundup WG®, Roundup Transorb R® and ZappQi® were used at a glyphosate dose of 720 g a.e. ha-1. The experiment was arranged in a randomized block design with four replications and two controls (hoed control and non-hoed control). The variables shoot, nodule dry matter, and soybean yield were not influenced by the different formulations of glyphosate. For mycorrhizal colonization, it was verified that a positive effect of the herbicide Roundup Original® regarding the hoed control was not continuous in the two years of the experiment. The variable number of nodules was the most affected by the glyphosate formulations tested.
