Estabelecimento e multiplicação in vitro de brotos no processo de micropropagação de cultivares de bananeira (Musa spp.)

A banana (Musa spp.) é uma das frutas mais consumidas no mundo, e amplamente cultivada no Brasil, porém doenças como as sigatokas, negra e amarela, vêm reduzindo a sua produção. A disponibilização imediata de novas cultivares resistentes às principais doenças é limitada pela propagação convencional. A micropropagação é uma alternativa para a produção de mudas com qualidade fitossanitária e vegetativa, mas apresenta fatores que dificultam sua aplicação como a contaminação por fungos e bactérias, associada à oxidação dos explantes. O objetivo desse trabalho foi adaptar e/ou otimizar as etapas do processo de micropropagação para diferentes cultivares de bananeira, por meio do controle de oxidação, contaminação, e multiplicação de brotos, sendo utilizadas as cultivares Caipira (AAA), BRS Caprichosa (AAAB), Pacovan Ken (AAAB), Preciosa (AAAB), PV 03-76 (AAAB), Thap Maeo (AAB). No estudo foram utilizados o antibiótico sulfato de estreptomicina e o fungicida Opera® (BASF) visando reduzir a contaminação in vitro provocada por bactérias e fungos, além do anti-oxidante PVP (polivinilpirrolidona) para controlar a oxidação. Houve redução da contaminação com uso do sulfato de estreptomicina à concentração de 100 mg L-1 e da oxidação com PVP a 4 g L-1. Na fase de multiplicação de brotos, as cultivares apresentaram médias que variaram de 1,90 a 4,75 brotos/explante. A cultivar caipira (AAA) destacou-se das demais com a maior taxa de multiplicação de brotos após três subcultivos, média de 41,50 brotos por rizoma.

Use of nitrification inhibitor DMPP to improve nitrogen recovery in irrigated wheat on a calcareous soil

The 3,4-dimethyilpyirazole phosphate (DMPP), commercialized as Entec, is a nitrification inhibitor developed by BASF (Germany) that may help to minimize N losses and to obtain a higher profit from N fertilizers. A two-year field trial was established in 2001 in the Northeast of Spain to assess the effects of DMPP on N use efficiency (NUE) and to determine the economic returns. Seven treatments have been carried out comparing the effect of DMPP on pig slurry and on mineral fertilizers. The application of DMPP resulted in better efficiency indexes on mineral fertilizers. An apparent nitrogen recovery of 0.465 kg kg-1, on average, was obtained for the Entec treatment. A net benefit of € 809 ha-1, on average, was obtained for the Entec treatment compared with € 607 ha-1 for the control treatment. The results of this study suggest that the nitrification inhibitor could improve farmer profit in irrigated wheat on a calcareous soil.

Use of new silica fillers as additives for polymers used in packaging of fruit

The objective of this work was to synthesize nanosilicas with different degree of hydrophobicity by the sol-gel method, using tetraethyl orthosilicate as a precursor. For this purpose, 3-aminopropyl triethoxysilane (APS) and 1,1,1,3,3,3 - hexamethyldisilazane (HMDS), were added during synthesis as modifiers. A commercial biopolymer (Hexamoll Dinch, BASF) intended for packaging of apples, was added to the new nanosilicas. The materials obtained were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, potentiometric titration, porosity, specific surface area and hydrophobicity/hydrophilicity by wetting test. Colorimetry was used to evaluate change in apple pulp color after contact with the different silicas.

Interestingly, BASF, Chevron Industries, and the Universidade Federal do Rio Grande do Sul (UFRGS) were discovered as higher patent applicant assignees. Differences in the patent application areas were also observed between these applicants, with new solvents and petrochemical applications as the areas of focus for the industrial applications (BASF and Chevron Industries), and energy production, catalysis, and chemical reaction media as the focus for the university applications.

Optimization of NMP extraction in 1, 3-butadiene production line

N-methylpyrrolidone is a powerful solvent for variety of chemical processes due to its vast chemical properties. It has been used in manufacturing processes of polymers, detergents, pharmaceuticals rubber and many more chemical substances. However, it creates large amount of residue in some of these processes which has to be dealt with. Many well known methods such as BASF in rubber producing units have tried to regenerate the solvent at the end of each run, however, there is still discarding of large amount of residue containing NMP, which over time, could cause environmental concerns. In this study, we have tried to optimize regeneration of the NMP extraction from butadiene production. It is shown that at higher temperatures NMP is separated from the residue with close to 90% efficiency, and the solvent residue proved to be the most effective with a 6: 1 ratio.

Desarrollo de un estado de la cuestión acerca de las interacciones entre el control de gestión y el aprendizaje organizacional.

Las organizaciones en la actualidad deben encontrar diferentes maneras de sobrevivir en un tiempo de rápida transformación. Uno de los mecanismos usados por las empresas para adaptarse a los cambios organizacionales son los sistemas de control de gestión, que a su vez permiten a las organizaciones hacer un seguimiento a sus procesos, para que la adaptabilidad sea efectiva. Otra variable importante para la adaptación es el aprendizaje organizacional siendo el proceso mediante el cual las organizaciones se adaptan a los cambios del entorno, tanto interno como externo de la compañía. Dado lo anterior, este proyecto se basa en la extracción de documentación soporte valido, que permita explorar las interacciones entre estos dos campos, los sistemas de control de gestión y el aprendizaje organizacional, además, analizar el impacto de estas interacciones en la perdurabilidad organizacional. ​

alpha-tocopherol affects androgen metabolism in male rat

The Alpha-Tocopherol Beta-Carotene Cancer Prevention Study has provided the first evidence implicating vitamin E in hormone synthesis. The effect of vitamin E on stereoidogenesis in testes and adrenal glands was assessed in growing rats using Affymetrix gene-chip technology. Dietary supplementation of rats with vitamin E (60 mg/kg feed) for a period of 429 days caused a significant repression of genes encoding for proteins centrally involved in the uptake (low-density lipoprotein receptor) and de novo synthesis (for example, 7-dehydrocholesterol reductase, 3-hydroxy-3-methylglutaryl coenzyme A synthase, 3-hydroxy-3-methylglutaryl-coenzyme A reductase, isopentenyl-diphosphate delta-isomerase, and farnesyl pyrophosphate synthetase) of cholesterol, the precursor of all steroid hormones. The present investigation indicates that dietary vitamin E may induce changes in stereoidogenesis by affecting cholesterol homeostasis.

Seletividade de herbicidas aplicados em pré-emergência sobre cultivares de batata

O presente trabalho foi realizado na Estação Experimental Agrícola da BASF S.A., situada na rodovia SP 310, km 144, no município de Santo Antonio da Posse-(SP), em área de Latossolo Vermelho distrófico com textura média. Quatro experimentos foram desenvolvidos com o objetivo de avaliar a seletividade dos herbicidas dimethenamid, metribuzin e linuron, aplicados em diferentes doses, na condição de pré-emergência, sobre as características de produção e qualidade dos tubérculos de quatro cultivares de batata (Solanum tuberosum L.). Utilizou-se, em todos os experimentos, o delineamento experimental de blocos ao acaso, com cinco repetições e parcelas de 21 m² (3 x 7 m). Os tratamentos utilizados foram: testemunha capinada, dimethenamid nas doses de 0,75, 1,50 e 3,00 kg ha-1, metribuzin a 0,48 e 0,72 kg ha-1 e linuron a 1,50 e 2,00 kg ha-1. Foram realizadas três avaliações visuais de fitotoxicidade aos 24, 31, e 42 dias após a aplicação (DAA). A severidade das injúrias visuais verificadas nas plantas das diferentes cultivares de batata foi dependente do herbicida, da dose aplicada e da cultivar utilizada. O herbicida dimethenamid, na dose de 3,00 kg ha-1, foi o tratamento que proporcionou as maiores porcentagens visuais de área foliar injuriada, no entanto tais sintomas desapareceram completamente aos 42 DAA. Nenhum tratamento com herbicida interferiu negativamente na produção de tubérculos, na massa seca dos tubérculos e no tamanho final dos tubérculos colhidos.

Influence of natural polymer derived from starch as a sensory modifier in sunscreen formulations

Background: Nowadays, there has been increased incidence of skin cancer, which is mainly related to increased sun exposure. Although sunscreen products may prevent the appearing of this disease, consumers may not use them due to some factors, including the sensory properties. The Aluminum Starch Octenylsuccinate (Dry-Flo® Pure, Akzo Nobel), an aluminum salt produced by the reaction of anhydride octenylsuccinic with starch, is able to improve the spreadability on the skin and reduce the oiliness of the formulation. Objective: To verify volunteers' acceptance for sunscreen formulation with natural polymer, compared with a control formulation (without polymer). Methods: To carry out the sensory analysis a formulation with or without 2. 0% Aluminum Starch Octenylsuccinate was prepared. Formulations had FPS 15, with critical wavelength of 353 nm, determined by testing in silico using the BASF® Sunscreen Simulator. Sensory analysis was performed on 60 students of both sexes, aged between 18 and 25 years, regular users of sunscreen products. Results: The results suggested that the polymer was able to promote a very soft and velvety feel on the skin when used in a sunscreen formulation, and it was able to mitigate and noticeably reduce the oiliness of the skin. Of the 60 volunteers who participated in the study, 45 volunteers (75%) considered that the polymer formulation provides little brightness or did not notice the difference in brightness of the skin after application. Conclusions: It was able to improve the sensory of the product, contributing to greater volunteers' acceptance.
