B vitamins are essential for human life and their disorders can cause a variety of diseases. Solid-phase extraction (SPE) coupled to LC-MS/MS is preferred technique determining multiple vitamins, however, complexity in real biological matrices makes it hard achieve satisfactory recovery accuracy when simultaneous detection. In this study, novel automated multi-cycle magnetic SPE (MSPE) the method was established using mixed-mode anion exchange adsorbent six functional including methylmalonic...
Permanent magnet motors are widely used in the driving system of electric vehicles because their high power density and small size. However, permanent motor is prone to demagnetization due complex operating environment characteristics motors. To ensure normal operation vehicles, fault diagnosis magnets should develop. In this study, thermal behavior a under local discussed. Results show that has significant effect on temperature motor; thus, added into input signals diagnosis. The healthy...
Background. Exercise is one of the recommended interventions for polycystic ovary syndrome (PCOS), and current evidence has shown that Tai chi may have favorable effects. The objective this randomized controlled pilot trial was to study feasibility potential effects overweight/obese adolescents young women with PCOS, so a future definitive (RCT) can be well designed implemented. Materials Methods. This recruited 50 patients who were randomly assigned two groups (Tai self-monitored exercise)...
For line start permanent magnet synchronous machines (LSPMSMs), the eddy current loss in rotor, which has of significant effects on rotor working temperature, may cause thermal demagnetization to magnet. Therefore, this paper addresses an investigation temperature distribution LSPMSM based a 6 kV, 315 kW prototype with solid starting cage bar. Firstly, distributions, obtained from 2-D transient electromagnetic field calculation, are determined as distributed heat source analyses. Then,...
The structure of a permanent magnet synchronous motor (PMSM), more precisely, its shape and dimension the stator slot can change magnetic field distribution tooth yoke. In addition, it also affects in air‐gap electrical loss rotor. As result, there is an effect on motor's internal temperature distribution. This study aims at investigating influence performance motor. To this extent, field‐circuit coupled model combining vector control strategy with finite element proposed. Based model,...
In this study, we developed and validated a simple, fast sensitive LC-MS/MS method for the measurement of tetrodotoxin (TTX) in human plasma. Three HILIC-type solid phase extraction (SPE) carriers (PSA, silica, Siphila i HILIX) with different stationary functional groups were compared. The HILIX SPE plate containing multi-carboxyl was finally selected due to obviously better recovery TTX (about 80% from plasma samples) than other two no significant matrix effects observed, which speculated...
Approximately 5%-20% of reproductive women suffer from polycystic ovary syndrome (PCOS). Auricular points acupressure (AA) may serve as alternative management for PCOS its benefits in both physical and psychological well-being. However, the effects AA insulin resistance (IR) overweight/obese have not been confirmed. The present study is designed a randomised, placebo-controlled pilot trial to evaluate effectiveness safety treating IR with PCOS. A total 60 eligible subjects will be randomised...
Normally, three-phase linear Hall sensor-based embedded magnetic encoder (EME) are used in permanent magnet synchronous motors (PMSMs) to detect the rotor angle, which prefilters suppress harmonic disturbance. However, due employment of prefilters, this EME system shows large estimated angle error at low-speed regions and weak dynamic response performance. In letter, a dual is proposed with help vector space decomposition (VSD) method. It can effectively eliminate interference without...
The rotor eddy current loss of high-speed permanent magnet motor has an important influence on the temperature distribution magnet. In traditional method, unbalanced in is ignored, and applied to calculation field form average heat density, which makes a certain error motors. This study proposes 50 kW 30,000 rpm prototype segmentation model considered this model, divided into different regions. According losses regions are obtained, then density motor. application proposed simple convenient,...
Accurate measurement of serum folate is essential for the diagnosis and management various disorders. This study aims to investigate between-method differences four immunoassays a rapid isotope-dilution liquid chromatography-tandem mass spectrometry (ID-LC-MS/MS) method.Roche Cobas (USA), Abbott Alinity i2000 Beckman Coulter Access Mindray CL-6000i (China), ID-LC-MS/MS method were compared using 46 human samples. The results analysed by Passing-Bablok regressions Bland-Altman plots. A bias...
Current evidence concerning the association between persistent organic pollutants (POPs) and polycystic ovary syndrome (PCOS) is inconsistent. The aim of present systematic review meta-analysis to evaluate role POPs in PCOS.Databases including PubMed, Embase, Web Science, CNKI will be searched identify qualified studies. All studies regarding PCOS included. primary outcome study levels serum subjects. Pooled analysis with corresponding 95% confidence intervals performed.The comprehensive...
The design and processing of conventional permanent magnet synchronous motors (PMSM) already have mature technology which reflect in the conformity product expectations. But problem inconsistency is serious mass production high-speed (HPMSM), performance often deviates from plan. In order to reduce influence these tolerances achieve purpose fine modeling accurate calculation, this paper study on assembly relationship between magnets (PMs) rotor core physical field. Taking 50 kW-30,000 rpm...
