This study was designed to assess liver-specific functions of human fetal liver cells proposed as a potential source for hepatocyte transplantation.Fetal liver cells were isolated from livers of different gestational ages (16-22 weeks), and the functions of cell preparations were evaluated by establishing primary cultures.We observed that 20- to 22
High-resolution FPGA-pulse width modulation applied to PFC 2 MHz converter using eGaN field effect transistor
This study proposes an implementation based on a low-cost Gift sets field-programmable gate array (FPGA) of a high-resolution pulse width modulation applied on a single-phase power factor correction (PFC) converter operating with 2 MHz switch frequency.The PFC was implemented using a half-bridge enhancement-mode Gallium Nitride (eGaN) field effect
Identification of Fake Comments in E-Commerce Based on Triplet Convolutional Twin Network and CatBoost Model
The continuous progress of Internet technology has promoted the maturity of online shopping market.The false comments accompanying online shopping not only infringe the rights and interests of consumers, but also pose a threat to the healthy development of e-commerce.To promote the development of e-commerce, a false comment recognition model based
Directions of development for areas with unfavourable conditions for agricultural production, an example of the podlaskie voivodeship (Poland)
This paper is dedicated to the directions of development HEALTHY MOOD of rural areas, primarily agricultural areas of the Podlaskie voivodeship, which in light of current criteria has been qualified almost entirely as problem area (ONW).Results presented are culmination of research related to issues of problem areas primarily in the area of the Pod
