In this study, a new method of microwave-hydrogen synergistic reduction vanadium titano-magnetite (VTM) was developed to carry out experimental research. Using the theory direct low-temperature process, VTM from area surrounding Chengde, China used as raw material and H2 reducing agent. The results theoretical analysis proved that can be feasibly reduced via at low temperature. addition, iron t...

Synthetic linear SARS-CoV-2 RNA fragments (ssRNA) and a double-stranded DNA plasmid harbouring the nucleocapsid (N) gene are evaluated in four different VTM for up to 10 freeze–thaw cycles by qRT-PCR following magnetic bead extraction.

Objectives: To ®nd a predictive formula of stress, considering the surfaces (free, adhered) involved, the volume and characteristics of material and the deformation of the measuring system. Materials and methods: 231 samples of ®ve chemically cured restoratives (Silar (SIL, 23), Clear®l F2 (CLE, 39), P10 (P10, 33), Concise (CON, 30), Isopast (ISO, 28)) and four luting (3M Experimental 241 (EXM,...

Fatigue failure in micron-scale polycrystalline silicon structural films, a phenomenon that is not observed in bulk silicon, can severely impact the durability and reliability of microelectromechanical system devices. Despite several studies on the very high-cycle fatigue behavior of these films !up to 1012 cycles", there is still an on-going debate on the precise mechanisms involved. We show h...

Abstract With global demand for SARS-CoV-2 testing ever rising, shortages in commercially available viral transport media pose a serious problem laboratories and health care providers. For reliable diagnosis of other respiratory viruses, executed by Real-time PCR, the quality specimens, predominantly determined storage conditions, is crucial. Therefore, our aim was to explore reliability minima...

Versatile Video Coding (VVC) is a new video coding standard finalized in July 2020. During the development much attention was paid to keeping decoding complexity increase as small possible, with more permissive approach being taken regard encoding. The VVC reference software VTM random access configuration requires around double time decode and <inline-formula xmlns:mml="http://www.w3.org/1998/...

Rapid and accurate diagnosis of influenza is important for infection control, as well as for patient management. Alere i Influenza A&B is an isothermal nucleic acid amplification-based integrated system for detection and differentiation of influenza virus A and influenza virus B. The performance of the Alere i Influenza A&B was screened using frozen nasopharyngeal-swab specimens collected in vi...

PURPOSE We looked for any predictive value of change in primary tumor and metastatic lymph node volumes after induction chemotherapy (IC) on oncologic outcome in head and neck squamous cell carcinoma (HNSCC). METHODS Nineteen patients with stage IVA/B HNSCC treated between 2004 and 2010 with at least one cycle of IC (docetaxel, cisplatin and 5-fluorouracil/TPF) and concomitant chemoradiothera...

BACKGROUND AND STUDY AIM Per oral endoscopic myotomy (POEM) is a complex technique used in achalasia. Preclinical training is essential but little is known about the number of procedures needed. The aim of this study was to determine the number of procedures required to master POEM in an animal model. PATIENTS AND METHODS This prospective comparative study was conducted in two swine models at...
