The hydraulic bulge test (HBT) method is proposed to determine material tensile strengths. The basic idea of HBT is similar to the small punch test (SPT), but inspired by the manufacturing process of rupture discs-high-pressure hydraulic oil is used instead of punch to cause specimen deformation. Compared with SPT method, the HBT method can avoid some of influence factors, such as punch dimensi...

Vasoactive drugs are normally utilized to elevate mean artery pressure and maintain adequate organ perfusion in clinical treatment. During the injection, morphological changes and the subsequent oxygen supply alteration in the brain, e.g., possible hypoxia, are prone to introduce serious damage and even dysfunction to the brain. Therefore, multiparameter monitoring of cerebral microvasculature ...

Our understanding of perfusion-based human brain mapping techniques relies on a detailed knowledge of the relationship between neuronal activity and cerebrovascular hemodynamics. We performed optical imaging of intrinsic signals at wavelengths sensitive to total hemoglobin (Hbt; which correlate with cerebral blood volume (CBV)) and deoxygenated hemoglobin (Hbr) directly in humans during neurosu...

Laccase-mediator systems (LMS) have been widely studied for their capacity to oxidize the nonphenolic subunits of lignin (70-90% of the polymer). The phenolic subunits (10-30% of the polymer), which can also be oxidized without mediators, have received considerably less attention. Consequently, it remains unclear to what extent the presence of a mediator influences the reactions of the phenolic...

With the exception of barley and rice, little is known about the existence of hemoglobins (Hbs) in cereals. This work reports the cloning and analysis of hb genes from maize (Zea mays ssp. mays) and teosinte (Zea mays ssp. parviglumis). Coding sequences of maize and teosinte hb genes (hbm and hbt, respectively) are highly similar to each other and are interrupted by three introns located at ide...

Understanding particle emission in relativistic nuclear collision is crucial in order to determine whether a phase transition to quark-gluon plasma has occurred. Particle interferometry was invented by Hanbury-Brown & Twiss (HBT) for stellar size determination [1] and is now employed in nuclear collisions [2–8]. It is a very powerful method to determine the 3-dimensional source sizes, lifetimes...

The objective of this study was to evaluate if transrectal optical tomography implemented at three wavelength bands for spectral detection could monitor changes of the hemoglobin oxygen saturation (StO2) in addition to those of the total hemoglobin concentration ([HbT]) in lesions of a canine prostate, including an induced tumor modeling canine prostate cancer. Near-infrared (NIR) optical tomog...

SiGe technology is sincerely challenging III/V and II/VI technologies in the realm of high frequency electronics applications, for example optical fibre and mobile communications. In this paper a model of SiGe HBT with uniform impurity doping in the base for high frequency application is studied. The high frequency parameters are extracted with the help of simulated Zand Yparameters of two port...

Patients with beta-thalassemia trait have been reported to present lower plasma concentrations of low-density lipoprotein (LDL) and lower frequencies of acute myocardial infarction than normal subjects. In this study, the metabolism of LDL was tested in 12 patients with heterozygous beta-thalassemia trait (HBT) and 13 healthy subjects without the disease by determining the plasma kinetics of an...
