The use of visible and near infrared reflectance spectroscopy to predict beef M. longissimus thoracis et lumborum quality attributes

Visible and near infrared reflectance spectroscopy was used to predict pH at 24 h (pH24) post-mortem, sarcomere length (SL), cooking loss (CL), Warner–Bratzler Shear Force (WBSF) and colour parameters (L*, a*, b*) in beef cattle samples. Samples from M. longissimus thoracis et lumborum from 30 bulls were aged at 4 C for 1, 3, 7 and 14 days and analysed for pH, SL, CL, WBSF and colour. NIRS calibrations for pH24, luminosity at 0 (L*t0) and 60 min (L*t60) showed good predictability (R2 = 0.97, 0.85 and 0.82; SECV = 0.10, 1.16, 1.36, respectively), whereas those related to the rest of the parameters were poore

Suplementacao alimentar de bovinos com misturas multiplas em pastagens de brachiaria brizantha cv. Marandu na seca.

Este trabalho foi realizado pela Embrapa Cerrados em uma fazenda particular, objetivando desenvolver estrategias de suplementacao alimentar de bovinos com Misturas Multiplas. Utilizou-se a ureia como substituto da proteina natural e o milho, como fonte de energia, em B. brizantha cv. Marandu, estabelecida em um Latossolo Vermelho-Escuro, textura argilosa. O experimento foi conduzido durante a seca de 1997 e durou 84 dias. Empregou-se 160 novilho Nelore, com peso medio de 175 kg arranjados em sistemas de pastejo continuo em quatro pastos, em delineamento experimental completamente casualizado, com quatro tratamentos: 1- Sal mineralizado com 38% de superfosfato triplo (Testemunha); 2- Milho triturado 30%, farelo de soja 15%, ureia 10%, sal mineralizado 35%, sal comum 10%; 3- Milho triturado 36,4%, farelo de soja 7,5%, ureia 11,1%, sal mineralizado 35%, sal comum 10%; 4- Milho triturado 42,7%, ureia 12,3%, sal mineralizado 35%, sal comum 10%. A disponibilidade de forragem, nos pastos durante o experimento, permaneceu acima 4500 kg de MS/ha. A pressao de pastejo variou de 7% a 8%, e a taxa de lotacao media foi de 1.0 UA/ha. O conteudo de proteina bruta baixou para menos de 6% em agosto, mas elevou-se acima desse valor nos demais meses. A menor digestibilidade (DIVMS) ocorreu em agosto, e a fibra em detergente neutro variou de 60% em junho e 72% em agosto. Os animais, suplementados com a mistura multipla da Embrapa Cerrados, ganharam peso semelhante aos que consumiram as outras misturas e superior aquelas que receberam apenas sal mineralizado. A suplementacao com Mistura Multipla da Embrapa Cerrados aumentou o lucro liquido por animal em 46%, com retorno de US$ 3.59 por dolar aplicado.bitstream/CPAC-2010/23742/1/bolpd-10.pd

Riding the (brain) waves! Using neural oscillations to inform bilingualism research

The study of the brains’ oscillatory activity has been a standard technique to gain insights into human neurocognition for a relatively long time. However, as a complementary analysis to ERPs, only very recently has it been utilized to study bilingualism and its neural underpinnings. Here, we provide a theoretical and methodological starter for scientists in the (psycho)linguistics and neurocognition of bilingualism field(s) to understand the bases and applications of this analytical tool. Towards this goal, we provide a description of the characteristics of the human neural (and its oscillatory) signal, followed by an in-depth description of various types of EEG oscillatory analyses, supplemented by figures and relevant examples. We then utilize the scant, yet emergent, literature on neural oscillations and bilingualism to highlight the potential of how analyzing neural oscillations can advance our understanding of the (psycho)linguistic and neurocognitive understanding of bilingualism

Holonomy corrected Schwarzschild black hole lensing

In the present work, we theoretically investigate gravitational lensing in the spacetime of a holonomy corrected Schwarzschild black hole. Analytical expressions for the light deflection angle are obtained in both the weak field limit and the strong field limit. Furthermore, we analyze observables, such as relativistic images and magnifications, and compare the results with those expected in a Schwarzschild spacetime. We discuss the possibilities and difficulties of investigating such a solution in practice

Magnetic carbon composites as recycling electron shuttles on anaerobic biotransformations

Book of Abstracts of CEB Annual Meeting 2017[Excerpt] The unique properties of magnetic nanoparticles (MNP), such as high surface area, magnetic, sorption and catalytic characteristics, make them very versatile for many applications in different areas including environmental remediation, as catalysts, adsorbents, immobilising agents for microorganisms and enzymes, and as supports for biofilm growth and water disinfectants. In order to improve their stability and to introduce additional surface properties and functionalities, MNP can be coated with carbon materials (CM) due to their chemical stability, biocompatibility and possibility of tailoring their textural and surface chemical properties for specific applications [1]. We have previously proved that various CM, including activated carbon, carbon xerogels and carbon nanotubes (CNT), can be used as redox mediators (RM) in anaerobic biotransformation, accelerating the electron transfer and, consequently, the reduction rates of organic compounds [1,2]. The combination of CM with MNP offers the possibility of creating magnetic carbon composites with synergistic properties: the adsorptive and catalytic properties of both and the magnetic character of MNP, improving the material performance and rendering it easier to be retained and recovered, by applying a magnetic field.
