Diante da perspectiva ambiental, há a necessidade de substituição tubetes polietileno por biodegradáveis. Alguns estudos relatam que propostas biodegradáveis não suportavam as condições ambientais nos viveiros ou favoreciam necessárias ao crescimento das mudas, implicando parâmetros morfológicos necessários atingir qualidade padrão ir à campo. O objetivo deste estudo foi avaliar os mudas jenipa...

From analysis of the DIRBE weekly averaged sky maps, we have detected substantial flux in the 60μm and 100μm channels in excess of expected zodiacal and Galactic emission. Two methods are used to separate zodiacal light from more distant emission. Method I makes use of the time-dependence of the North-South annual variation observed at the ecliptic poles. This method is robust against errors in...

BACKGROUND Adenosine analogs have been shown to produce antinociception after intrathecal administration. To determine the adenosine receptor subtype involved in spinal antinociception, the effects of selective agonists and an antagonist on the evoked potentials recorded from a neonatal rat spinal cord were studied. The measured potentials are a slow ventral root potential (slow VRP), which is ...

A dosimetry system based on Al2O3:C radioluminescence (RL), and RADPOS, a novel 4D dosimetry system using microMOSFETs, were used to measure total scatter factors, (S(c,p))(f(clin))(det), for the CyberKnife robotic radiosugery system. New Monte Carlo calculated correction factors are presented and applied for the RL detector response for the 5, 7.5 and 10 mm collimators in order to correct for ...

The risks involved in nighttime driving include drowsy drivers and dangerous vehicles. Prominent among the more dangerous vehicles around at night are the larger vehicles which are usually moving faster at night on a highway. In addition, the risk level of driving around larger vehicles rises significantly when the driver's attention becomes distracted, even for a short period of time. For the ...

Video captioning automatically generates short descriptions of the video content, usually in form a single sentence. Many methods have been proposed for solving this task. A large dataset called MSR to Text (MSR-VTT) is often used as benchmark testing performance methods. However, we found that human annotations, i.e., contents are quite noisy, e.g., there many duplicate captions and contain gr...

A magnetically shielded room (MSR) equipped with an automatic door is designed and developed to improve a convenience of operation. The MSR for biomagnetic measurements (e.g., magneto-encephalography), it required that such has high shielding performance because biomagnetism extremely smaller than environmental magnetic noises. In particular, we devise the laminar structure shield plates preven...

For a magnetically suspended control moment gyro (MSCMG), the high-speed rotor is actively by magnetic bearings of 5-DOF, but nonlinearity suspension force one main reasons for poor accuracy radial translation (MSR). To solve this problem, here, characteristics are analyzed, and nonlinear dynamic model MSR established. A sliding mode (SMC) based on neural network presented, basis function (RBF)...
