The present article provides an overview of the various techniques used in the past, and being developed in the present, to separate sexes. It also describes and critically assesses the strength and limitations of current attempts to improve existing methods and to develop novel trans- genic ...
Separation and purification of active components from algae are great significant to the development of algal natural products and new drugs.The recent advance on the extraction,separation and purification techniques for the algae active components are summarized and reviewed in this paper.Especially,the...
TECHNIQUES FOR FABRICATING WAVEGUIDE FACETS AND DIE SEPARATIONA fabrication method includes arranging a plurality of dice on a substrate and performing a first etching process that etches a first layer of the substrate at a boundary between adjacent dice on the substrate. The etching forms facets of...
Spectral separation techniques can be categorized into holographic and diffractive filters, thin-film interference filters, and selective absorbers [57], as shown in Fig. 5. The working principles, advantages/disadvantages, and applications of these three technologies will be introduced in the following...
For the purposes of this description, when we refer to the principles of chromatography or chromatographic separations generally, we intend to denote those separation techniques which involve selective retention on the active material of the column of a particular component of a mixture or the retardat...
Sperm selection in assisted reproductive techniques The application of assisted techniques (ART) has provided help to many men seeking to father a child, although the current success rates of these procedure... U Paasch,S Grunewald,HJ Glander - 《Society of Reproduction & Fertility Supplement》 被...
at least one of which is selectively sorbed by contact with solid sorbent particles such as zeolite, utilizing a simulated countercurrent flow system as hereinafter illustrated in detail, the improvement relating to discovery of process techniques which enables the separation of the selectively sorbed co...
In the gravity stage, heavy medium separation techniques are used for discarding coarse dolomite [8,9]. The typical heavy medium separation equipment used in Yichang phosphate ore is heavy medium cyclone. The gravity concentrate is then subjected to double reverse flotation for further discarding of...
depending on the process scale and the desired specifications. These bi-phasic techniques are based on intrinsic interactions between metal ions and organic molecules dissolved in an organic diluent (liquid-liquid extraction) or grafted onto a solid matrix (chromatography). Ideally, these organic molecu...
This raises critical questions about the applicability of the current definition of 𝑇(𝜑,𝑑)T(φ,d) for agglomeration-based separation techniques, as 𝑇(𝜑,𝑑)T(φ,d) shifts and changes depending on the initial state 𝑛(𝐱,0)n(x,0) it is applied to. However, if a ...
