The Mulberry leaves extract acts as both reducing agent and stabilizing agent. The UV-Vis spectrum shows peak at 430 nm. The TEM image of synthesized AgNPs sample shows spherical shaped particles whose size range from 15 to 20 nm. TEM image of nano silver solution sample synthesized by microwave assisted method shows nearly spherical particles with an average particle size of 10 nm. The absorption UV-vis spectrum of silver nanoparticles synthesized by microwave assisted method (AgNPsmw) shows a sharp absorption band around 415 nm. After two month storage of AgNPsmw, the absorption spectrum of AgNPsmw was taken again. The UV-Vis spectrum shows negligible peak changes of silver nanoparticles have occurred after two months of storage. The synthesized AgNPs material could be used as an antimic...

In most cases of MHL, the α fetoprotein (AFP) level is within the normal limits, only in a few cases, increased AFP has been described which usually causes misdiagnosis of hepatoblastoma. We report a case of a 3-month-old paediatric patient who was incidentally detected with a very high level of AFP, at 6388.4 ng ml−1. Ultrasound revealed a right liver tumour, segment VI, measuring at 56 × 53 mm. According to images of ultrasound and MRI, the diagnosis was mesenchymal hepatic sarcoma. The paediatric patient had surgery to remove the entire liver segment containing the tumour. Micropathological examination showed that the tumour was a MHL. The serum AFP level fell rapidly to near normal following the surgery. The MHL benign liver tumour with an atypical presentation caused a very high AFP level. This was a rare clinical case, and it was difficult to diagnose.

There are some optimization methods for gaslift well in Vietnam, nearly all uses analytical mathematic method with solutions finding the extrema for multivariable function. This paper presents an optimization method for group of gaslift well to increase the oil rate for Dai Hung field, Nam Con Son Basin, offshore Vietnam.

X-ray diffraction patterns confirmed a tetragonal crystalline structure. The luminescent spectra of CAS: Ce3+, Dy3+ phosphors consist a board band with peaking at 420 nm corresponding to the luminescence of Ce3+ ions and narrow lines of Dy3+ ions. The energy transfer from Ce3+ ion to Dy3+ ion is presented and discussed

In this study, the authors aim to measure customer satisfaction towards online shopping process and home delivery service, and seek to empirically establish a practical online service model for shopping malls selling electronics devices in Vietnam. The theoretical framework is drawn out, and questionnaire items are designed based on the factors chosen. The data are carried out by using multiple statistical analyses, including exploratory factor analysis, reliability analysis, mean point value, and multiple linear regressions. The regression analysis results show that the most significant factors affecting customer satisfaction towards online shopping activities are product feature satisfaction, tangibility, empathy, effectiveness and understandability. This study provides significant suggestions for Vietnamese mall owners to relieve consumers' security concerns about online shopping and to raise their belief in the trustworthiness of e-service provided.
