Seeds of plants from Ipomoea genera contain numerous ergot alkaloids, including psychoactive ergine and ergometrine, and are often abused as so-called "legal highs." In this work, an analytical method for determination of ergine and ergometrine, and identification of other alkaloids was developed, optimized, and validated. Three extraction techniques, ultrasound-assisted extraction in bath, or ...

The impregnation of continuous carbon fibre roving with thermoplastic melt is a challenging task due to the high viscosity and surface tension melt. A new technique under development utilizing ultrasonic oscillations within which encloses roving, achieve impregnation. Despite processing being very efficient, specific conditions created in have never been studied before. This study investigated ...

S16 ENDOSCOPIC ULTRASOUND / VOLUME 6 / SUPPLEMENT 1 / AUGUST 2017 for cases which require immunohistochemistry, for example, neuroendocrine tumor, lymphoma, and mediastinal tumors. (3) EUS is the most important tool for pancreatic cystic lesions. (4) EUS is an important tool for diagnosis of CBD and gallbladder masses. EUS gives accurate diagnosis in gastric submucosal lesions, infiltrative gas...

The aim of this study was to investigate the influence thermal treatment and ultrasound on activity β-glucosidase lipoxygenase, enzymes that determine phenolic composition sensory profile virgin olive oil. Enzyme determined spectrophotometrically in model systems consisting commercial their substrates. Thermal performed by tempering substrates at temperatures between 15 40 °C. measured 1 min af...

In this paper, we explore the potentialities of using ultrasound waves as a post-irradiation treatment after proton beam writing (PBW) patterning PTFE. To that end, 2-mm-thick foils PTFE were irradiated with 2.2 MeV protons an average current 50 pA. Straight line structures patterned on polymer 3.5 × μm2 focused beam. Post-irradiation polymers placed in heat bath at 60 °C and immersed either di...

The aim of this study was to explore the feasibility and clinical value of ultrasound combined with a warm bath test in assessing the differences in reactivity of toe microcirculation between healthy adults and patients with type 2 diabetes mellitus (T2DM).A total of 56 T2DM patients were recruited as case group, whereas 50 healthy volunteers were enrolled as control group.Fasting blood glucose...

We study the coherence trapping of a qubit correlated initially with a non-Markovian bath in a pure dephasing channel. By considering the initial qubit-bath correlation and the bath spectral density, we find that the initial qubit-bath correlation can lead to a more efficient coherence trapping than that of the initially separable qubit-bath state. The stationary coherence in the long time limi...

In this study, a rapid fabrication method was developed to prepare hydrogel structures with high mechanical strength and low attenuation coefficient for ultrasound scanning. Poly acrylic acid (PAA) first prepared via free radical polymerization approach. To shorten the process time (~ 30 min in water bath), microwave heating applied facilitate reaction reduce down 80 s. The produced hydrogels s...

Drawing lessons from the development of cities at home and abroad success and lost experience, through practice research, this paper systemically analysis the evolution of urban economy space. In the scope of global industrial supply chain’s recomposing, it is discusses that modern city’s function structure characteristic, focusing “integrative logistics management service”. According to Dalian...
