          Differential Expression of Genes Associated with Endomembrane Transport and Cell Wall Metabolism during Ripening of ‘Chimarrita’ and ‘Granada’ Peach

          Camila Pegoraro,Roberta Manica-Berto,F?bio Clasen Chaves,Carolina Terra Borges,Jader Job Franco,Cesar Valmor Rombaldi,Jorge Adolfo Silva 한국원예학회 2010 Horticulture, Environment, and Biotechnology Vol.51 No.3

          Expression of genes involved in endomembrane transport and cell wall metabolism, particularly in synthesis and degradation of cell wall macromolecules were compared during the ripening of a white melting flesh cultivar, Chimarrita and a yellow non-melting flesh cultivar, Granada in order to evaluate their association with fruit softening. In both, most genes were up-regulated as ripening evolved. In ‘Chimarrita’, overall higher transcript accumulation occurred at 95 days after anthesis, while in ‘Granada’ higher relative transcription was detected at 115 days after anthesis. Although transcript accumulation was correlated with fruit softening, the process does not seem to be totally dependent on the set of studied genes, since the peak of RNA abundance occurred when flesh firmness had already decreased.

          Application the mechanism-based strain gradient plasticity theory to model the hot deformation behavior of functionally graded steels

          Salavati, Hadi,Alizadeh, Yoness,Berto, Filippo Techno-Press 2014 Structural Engineering and Mechanics, An Int'l Jou Vol.51 No.4

          Functionally graded steels (FGSs) are a family of functionally graded materials (FGMs) consisting of ferrite (${\alpha}$), austenite (${\gamma}$), bainite (${\beta}$) and martensite (M) phases placed on each other in different configurations and produced via electroslag remelting (ESR). In this research, the flow stress of dual layer austenitic-martensitic functionally graded steels under hot deformation loading has been modeled considering the constitutive equations which describe the continuous effect of temperature and strain rate on the flow stress. The mechanism-based strain gradient plasticity theory is used here to determine the position of each layer considering the relationship between the hardness of the layer and the composite dislocation density profile. Then, the released energy of each layer under a specified loading condition (temperature and strain rate) is related to the dislocation density utilizing the mechanism-based strain gradient plasticity theory. The flow stress of the considered FGS is obtained by using the appropriate coefficients in the constitutive equations of each layer. Finally, the theoretical model is compared with the experimental results measured in the temperature range $1000-1200^{\circ}C$ and strain rate 0.01-1 s-1 and a sound agreement is found.

          Effect of Glutamine, Glutamic Acid and Nucleotides on the Turnover of Carbon (δ<sup>13</sup>C) in Organs of Weaned Piglets

          Amorim, Alessandro Borges,Berto, Dirlei Antonio,Saleh, Mayra Anton Dib,Telles, Filipe Garcia,Denadai, Juliana Celia,Sartori, Maria Marcia Pereira,Luiggi, Fabiana Golin,Santos, Luan Sousa,Ducatti, Carl Asian Australasian Association of Animal Productio 2016 Animal Bioscience Vol.29 No.8

          Morphological and physiological alterations occur in the digestive system of weanling piglets, compromising the performance in subsequent phases. This experiment aimed at verifying the influence of glutamine, glutamate and nucleotides on the carbon turnover in the pancreas and liver of piglets weaned at 21 days of age. Four diets were evaluated: glutamine, glutamic acid or nucleotides-free diet (CD); containing 1% glutamine (GD); containing 1% glutamic acid (GAD) and containing 1% nucleotides (ND). One hundred and twenty-three piglets were utilized with three pigs slaughtered at day zero (weaning day) and three at each one of the experimental days (1, 2, 4, 5, 7, 9, 13, 20, 27, and 49 post-weaning), in order to collect organ samples, which were analyzed for the ${\delta}^{13}C$ isotopic composition and compared by means of time. No differences were found (p>0.05) among treatments for the turnover of the $^{13}C$ in the pancreas ($T_{50%}$ = 13.91, 14.37, 11.07, and 9.34 days; $T_{95%}$ = 46.22, 47.73, 36.79, and 31.04 days for CD, GD, GAD, and ND, respectively). In the liver, the ND presented accelerated values of carbon turnover ($T_{50%}=7.36$ and $T_{95%}=24.47days$) in relation to the values obtained for the GD ($T_{50%}=10.15$ and $T_{95%}=33.74days$). However, the values obtained for the CD ($T_{50%}=9.12$ and $T_{95%}=30.31days$) and GAD ($T_{50%}=7.83$ and $T_{95%}=26.03days$) had no differences (p>0.05) among other diets. The technique of $^{13}C$ isotopic dilution demonstrated trophic action of nucleotides in the liver.

          Mixed mode fracture assessment of U-notched graphite Brazilian disk specimens by means of the local energy

          Torabi, A.R.,Berto, F. Techno-Press 2014 Structural Engineering and Mechanics, An Int'l Jou Vol.50 No.6

          A fracture criterion based on the strain energy density (SED) over a control volume, which embraces the notch edge, is employed in the present paper to assess the fracture loads of some U-notched Brazilian disk (UNBD) specimens. The specimens are made of commercial graphite and have been tested under pure mode I, pure mode II and mixed mode I/II loading. The results show that the SED criterion allows to successfully assess the fracture loads of graphite specimens for different notch tip radii and various mode mixity conditions with discrepancies that fall inside the scatter band of ${\pm}20%$.

          Averaged strain energy density to assess mixed mode I/III fracture of U-notched GPPS samples

          Saboori, Behnam,Torabi, A.R.,Berto, F.,Razavi, S.M.J. Techno-Press 2018 Structural Engineering and Mechanics, An Int'l Jou Vol.65 No.6

          In the present contribution, fracture resistance of U-notched GPPS members under mixed mode I/III loading conditions is assessed by using the Averaged Strain Energy Density (ASED) criterion. This criterion has been founded based on the ASED parameter averaged over a well-defined control volume embracing the notch edge. The validation of the theoretical criterion predictions is evaluated through comparing with the results of a series of mixed mode I/III fracture tests conducted on rectangular-shaped GPPS specimens weakened by a single edge U-notch. A recently developed apparatus for mixed mode I/III fracture experiments is employed for measuring the fracture loads of the specimens. The test samples are fabricated with different notch tip radii with the aim of evaluating the influence of this major feature of the U-notched components on the mixed mode I/III fracture behavior. It is shown that the onset of brittle fracture in U-notched GPPS specimens under various combinations of tension and out-of-plane shear can well be predicted by means of the ASED criterion.

          Functionally graded steels (FGSs) are a family of functionally graded materials (FGMs) consisting of ferrite (α), austenite (γ), bainite (β) and martensite (M) phases placed on each other in different configurations and produced via electroslag remelting (ESR).

          Structural response of corroded RC beams: a comprehensive damage approach

          Irene Barbara Nina Finozzi,Luisa Berto,Anna Saetta 사단법인 한국계산역학회 2015 Computers and Concrete, An International Journal Vol.15 No.3

          In this work, a comprehensive approach to model the structural behaviour of Reinforced Concrete (RC) beams subjected to reinforcement corrosion is proposed. The coupled environmental – mechanical damage model developed by some of the authors is enhanced for considering the main effects of corrosion on concrete, on composite interaction between reinforcement bars and concrete and on steel reinforcement. This approach is adopted for reproducing a set of experimental tests on RC beams with different corrosion degrees. After the simulation of the sound beams, the main parameters involved in the relationships characterizing the effects of corrosion are calibrated and tested, referring to one degraded beam. Then, in order to validate the proposed approach and to assess its ability to predict the structural response of deteriorated elements, several corroded beams are analyzed. The numerical results show a good agreement with the experimental ones: in particular, the proposed model properly predicts the structural response in terms of both failure mode and load-deflection curves, with increasing corrosion level.

        • Communication between CAN Bus Control Devices and Virtual Machines

          Richard Gagne,Vincent Remillard,Luca Berto,Lionel Pierreton 유공압건설기계학회 2017 유공압건설기계학회 학술대회논문집 Vol.2017 No.5

          The fluid power industry has seen significant changes in the last decade, following the electrification of hydraulic technologies. By adding intelligence to hydraulic and pneumatic manufacturers’ components, designing and testing new fluid power applications require the additional expertise of control specialists. Since fluid power and control specialists use different CAE tools to create and virtually test their respective design, there is a need to create an integrated test environment to better communicate, understand and specify requirements of electro-hydraulic systems. In this paper, we will demonstrate how virtual components up to a complete machine developed on simulation software can be controlled by physical control devices (joystick, controllers…) using CAN bus communication. Examples of this will be illustrated for virtual systems built according to manufacturers’ specifications in Automation Studio™ and communicating with the physical controllers: a hydraulic simulation model (ex.: Eaton CMA valves) communicating with a programmable controller and multiple devices as well as Eaton HFX Controller, Danfoss PLUS+1<SUP>®</SUP> microcontroller or HydraForce CoreTek controller.
