Research Progress on the Effect of Oil Preparation Technology on Lipid Concomitants in Rapeseed Oil [PDF]
, 2023 The major route of rapeseed utilization is by the preparation of rapeseed oil. Different oil preparation technologies have a significant influence on lipid concomitants (including polyphenols, phytosterols, tocopherols, and β-carotene) in rapeseed oil ...

Overreliance on Orthographic Similarity in L2‐Japanese Conceptual Processing by L1‐Chinese Learners
International Journal of Applied Linguistics, EarlyView.ABSTRACT Orthographic and phonological similarities between first (L1) and second (L2) languages can facilitate L2 processing. Particularly, L1‐Chinese learners of L2‐Japanese can benefit from the shared morphosyllabic Chinese characters (Japanese kanji/Chinese hanzi) because of their similar orthographies.

Genomic responses to increased temperature and pollinator selection in Brassica rapa L.
New Phytologist, EarlyView.Summary Rapid environmental change reshapes both abiotic stress and biotic interactions, yet it remains unclear how these combined forces structure plants' genomic adaptation. In particular, the joint influence of temperature and pollinator identity, two ecological axes undergoing simultaneous global shifts, has rarely been quantified at genomic ...

The Preliminary Study of Function of Arabidopsis Gene SAV7 [PDF]
, 2016 光和温度都是保障植物正常生长的极其重要的因素。植物为适应各种复杂多变的外界环境，已经进化出一套能够感应光和温度变化，并由此激发一系列的适应性反应机制。当植物种植过于密集而造成遮荫时，喜阳植物拟南芥会感应到光强以及红光：远红光的比例（R:FR）的下降，表现叶柄和下胚轴的快速生长，叶片偏下性生长的增强，以及叶绿素含量降低等变化，称为避荫综合症(ShadeAvoidanceSyndrome，SAS)，使其逃离遮荫环境来竞争有限的光资源。同样，当环境温度升高时候（29℃），拟南芥也能感受到这样细微的变化 ...

菜籽油中内源性香兰素的形成及含量研究Formation and content of endogenous vanillin in rapeseed oil
Zhongguo youzhi为探究菜籽油中是否存在内源性香兰素,对不同产地、加工工段、炒制温度的油菜籽及菜籽油中香兰素、甲基香兰素和乙基香兰素进行了检测。结果表明：所有样本中均未检出甲基香兰素和乙基香兰素；不同产地油菜籽中香兰素含量差异较大，含量范围为123.55～1 669.25 μg/kg；加工过程中，炒制油菜籽中香兰素含量较炒制前大幅增加，且其压榨菜籽饼中的香兰素含量高于压榨菜籽原油中的；随着炒制温度的上升，炒制油菜籽、压榨菜籽原油、压榨菜籽饼中香兰素含量增加，含量范围为189.93～5 080.00 μg/kg。综上 ...

油菜籽微波预处理的干燥动力学及模型研究Drying kinetics and model of rapeseed by microwave pretreatment
Zhongguo youzhi, 2022 为了探明油菜籽微波预处理过程中的水分变化情况，建立油菜籽微波预处理干燥模型，对油菜籽在料层厚度12 mm、不同微波功率（1.0、1.5、2.0 kW）以及微波功率1.5 kW、不同料层厚度（6、12、18 mm）下预处理后的含水率、水分比和失水速率的变化情况进行了研究，并以常用的3种干燥模型指数模型、单项扩散模型和Page模型进行了数据拟合。结果表明:微波功率越高、料层越薄，油菜籽水分流失越快，微波预处理时间越短；微波预处理过程中油菜籽水分变化情况与Page模型拟合度最好。 In order to ...

Eyes on nature: Embedded vision cameras for terrestrial biodiversity monitoring
Methods in Ecology and Evolution, Volume 15, Issue 12, Page 2262-2275, December 2024.Abstract We need comprehensive information to manage and protect biodiversity in the face of global environmental challenges, and artificial intelligence is required to generate that information from vast amounts of biodiversity data. Currently, vision‐based monitoring methods are heterogenous; they poorly cover spatial and temporal dimensions, overly ...
