Abstract This study aimed to evaluate the use of 1 Hz pulsed magnetic field (PMF) in preservation fresh ground beef during aerobic refrigerated storage. Supraspinatus muscle from Angus cattle was and aerobically packaged into 21 portions. These portions were divided three treatment groups: not exposed PMF (control); for 2 h (PMF‐2h) 12 days (PMF‐12d). Packages all groups stored dark at 4°C. One package each group used microbiological assays analyses pH, instrumental color, myoglobin lipid...
This research presents a noninvasive method for the acquisition of brain electrical signal in rat. Was used an electroencephalography (EEG) system developed bovine and adapted to rats. The bipolar electrode (needle electrodes) was glued on surface head animal without surgical procedures other tail, as ground. EEG activity sampled at 120Hz hour. accuracy precision measurement performed using Fourier analysis energy. For this, digital divided into sections successive 3 seconds decomposed four...
Complexity measurement using Lempel and Ziv algorithm (LZ) has been used to analyze physiological data. This work shows that the complexity of EEG signals wavelets transforms is independent electrode position dependent on cognitive tasks brain activity. database with 122 subjects from public dataset was in this study. have spontaneous evoked potential (EP) data a 64-multielectrode array under variety conditions collected at several centers United States, sponsored by National Institute...
Tryptophan is an essential amino acid precursor of neurotransmitter serotonin and triptamine. During its metabolism, indole-3-acetic (IAA) generated; this substance presents both antioxidant prooxidant effects in different biological systems addition to hipoglicemic effects. To date, electroencephalography (EEG) has been used evaluate the temporal effect several substances neurotransmission. The goal study was characterize IAA brain by analysing EEG signal oxidative status means biochemical...
The article aims to present a methodology determine the positioning of pigs in stall or barn, using value receiver signal strength indicator (RSSI), measured between mobile device carried by pig and three fixed devices. RSSI data were processed neural network artificial multilayer perceptron (PMC), responsible for interpreting signals correlate them with Cartesian coordinates X Y location pig. An experiment was conducted collect at Faculty Animal Science Food Engineering (FZEA / USP) an area...

Para probar aplicabilidad las redes sensores inalámbricos campo, se construyó una...
Modelos experimentais e teóricos do fluxo de pedestres em lugares alta concentração pessoas situações pânico têm mostrado que a presença determinados obstáculos perto das portas pode paradoxalmente aumentar velocidade evacuação. Experiências análogas, com grãos vidro escoam um silo retangular bidimensional, indicaram posição disco circular (obstáculo) consideravelmente saída dos grãos. Neste artigo foi desenvolvida uma versão tridimensional problema anterior. Um sistema experimental...
Electroencephalography (EEG) is the most common method to access brain information. Techniques monitor and extract signal characteristics in farm animals are not as developed those for humans laboratory animals. The objective of this study was develop a noninvasive monitoring signals cattle, allowing move freely, characterize these signals. Brain from six Holstein heifers that could freely paddock compartment were acquired. control group consisted same number bovines, contained climatic...

Anteriormente estudamos a vazão de grãos arroz um silo cilíndrico, em que os dentro do cilindro eram separados por uma barreira vertical duas partes iguais. Neste artigo retomamos experimentos arroz, mas agora com "obstruções" forma esferas e cones. Na maior parte das configurações testadas as cones não constituem obstrução para saída dos grãos. Pelo contrário, eles se transformam facilitadores. O valor máximo da velocidade média parece depender muito tipo específico "obstrução". A...
O fluxo de materiais granulares é pouco discutido nos livros física básica, apesar que sistemas grãos estão muito presentes na vida cotidiana. Este trabalho mostra o desenvolvimento um sistema experimental relativamente simples para estudar a vazão arroz e açúcar. aparelho constituído por silo cilíndrico com uma abertura circular no fundo balança. A balança conectada computador monitorar massa como função do tempo dos saem silo. Foram realizadas medidas diferentes diâmetros da saída alturas...
