Slowly digestible starch is the starch fraction that is digested at a slow rate in the body, meaning it is broken down by the digestive enzyme in human body during 20 to 120 min. after eating. Recently, slowly digestible starch (SDS) and resistant starch (RS) are widely studied worldwide because of their various positive health effects: releasing glucose at a slow rate, thereby maintaining sufficient blood glucose, glycemic index and insulin levels, reducing the risk of Type II diabetes, etc...

Centrifugal concrete products are manufactured using specific technology that changes the concrete proportion during consolidation. The bleeding of water reduces the water-to-cement ratio and increases the compressive strength of concrete. This affects the strength of the concrete determined on conventional casted cylinders, centrifuged hollow cylinders, and drilled cores from piles.

Accordingly, there is a negative relationship between TA and student achievement. Academic under-achievement has been more prevalent among high-test anxiety students. Therefore, understanding test anxiety from students’ perspective would contribute to reducing negative TA and enhancing positive performance. This study aims to investigate TA among English-major students at Thuyloi University on the basis of worry, emotionality, interference, and lack of confidence.

In this study, we propose a novel approach using the oscillation characteristics of the RMS current as the input to machine learning models, combined with the confident learning technique. Using the oscillation characteristics obtained by taking a discrete Fourier transform (DFT) of the RMS current as model input, we aim to reduce the computational requirements of the machine learning models.

This paper proposes a low-voltage ridethrough (LVRT) capability for a doubly-fed induction generator (DFIG) wind turbine (WT) system. With the proposed method, series grid-side converter (SGSC) in which its DC-side connected at the DC bus of the back-toback converters and its AC-side connected in series with line through transformer have been applied, enables to compensate a voltage response of the system during the grid faults and to reduce the capital cost.
