Does ultrafiltration have a lasting effect on the physico-chemical properties of the casein micelles?
The objective of this work was to determine if concentration of milk using ultrafiltration (in the absence of diafiltration) affects the physico-chemical properties of the casein micelles. The milk, once concentrated, was brought back to its original concentration and the physico-chemical properties as well as its susceptibility to rennet induced gelation were assessed. Although much is underst...
متن کاملAn Improved Neural Segmentation Method Based on U-NET
摘要:局部麻醉技术作为现代社会最为常见的麻醉技 术,具有安全性高,副作用小等优势。通过分析超声 图像,分割图像中的神经区域,有助于提升局部麻醉 手术的成功率。卷积神经网络作为目前最为高效的图 像处理方法之一,具有准确性高,预处理少等优势。 通过卷积神经网络来对超声图像中的神经区域进行分 割,速度更快,准确性更高。目前已有的图像分割网 络结构主要有U-NET[1],SegNet[2]。U-NET网络训练 时间短,训练参数较少,但深度略有不足。SegNet 网 络层次较深,训练时间过长,但对训练样本需求较多 由于医学样本数量有限,会对模型训练产生一定影响。 本文我们将采用一种改进后的 U-NET 网络结构来对超 声图像中的神经区域进行分割,改进后的 U-NET 网络 结构加入的残差网络(residual network)[3],并对每一层 结果进行规范化(batch normalizat...
متن کاملContinuous raw skim milk processing by pulsed electric field at non-lethal temperature: effect on microbial inactivation and functional properties
Pulsed electric field (PEF) is an emerging non-thermal processing technology used to inactivate microorganisms in liquid foods such as milk. The objective of this research was to study the effectiveness of continuous PEF equipment (square wave pulses) on total microorganisms of raw skim milk and on Salmonella enteritidis inactivation under moderate temperatures (T < 50 °C). Processing parameter...
متن کاملStudies of casein micelle structure: the past and the present
At the heart of the milk system are the colloidal casein-calcium-transport complexes termed the casein micelles. The application of physical chemical techniques such as light, neutron, and X-ray scattering, and Electron Microscopy (EM) has yielded a wealth of experimental detail concerning the structure of the casein micelle. From these experimental data bases have arisen two conflicting models...
متن کاملUsing Argumentative Zones for Extractive Summarization of Scientific Articles
Information structure, i.e the way speakers construct sentences to present new information in the context of old, can capture rich linguistic information about the discourse structure of scientific documents. Information structure has been found useful for important Natural Language Processing (NLP) tasks, such as information retrieval and extraction. Since scientific articles typically follow ...
