Self-production

Modem planar chromatography is suitable not only for qualitative and quantitative analysis but also for preparative purposes. The separation efficiency of a thin-layer chromatographic system is independent of this intended purpose and is mainly determined by the quahty of the stationary phase, that is to say, by the applied coated layer. Therefore, progress in modem planar chromatography can be attributed not only to the development of the efficiency of the instmments but also to a large extent to the availability of high-quahty precoated layers. And today, as in the past, bulk sorbents for self production, especially of preparative layer chromatography (PLC) layers, are widely used. 

John von Neumann constructed several models (originally known as kinematic models ) with the goal of incorporating the logical core of self-production into the system. Others studied von Neumann s model and modified it, for example, Walter Fontana, who devised the AlChemy (Algorithmic Chemistry) system. This can be described as artificial chemistry, an evolution reactor in which the objects which react are not molecules but mathematical functions. 

The molecules DNA and RNA are considered in autopoiesis only as participants in the cell s self-production and not for their ability to self-reproduce and/or evolve. Varela and Maturana often emphasize that before one can talk about the properties of life, one has to have a place to host them. The container and the logic must be there first. Likewise, in describing a car, before talking about the nature of the fuel,...

When the regenerative pathway from acetate to oxaloacetate is included, the rTCA cycle develops the possibility of self-production, increasing the density of catalytic oxaloacetate molecules and hence the bulk rate of acetate synthesis from CO2. The gain in this cycle enables an exponentially growing relaxation process to... 

Since the sequence of dimensional terms in the covariance does not affect the results, that is, cov(x,y) = cov(y,x), the covariance matrix is a symmetric one. The main diagonal shows the self-products and, thus, the variances for the dimension.

The mechanical performance of electrospun nanofibers concerning nanocomposites can be discussed at different levels such as mechanical properties of single nanofibers, nano-fibrous self-products, and nanofiber reinforced composites as well. When designing composites it is crucial to know the mechanical parameters, behavior and damage process of the nanofibrous materials. 

BPj, borosilicate, SiO, ZrSiO, and ZrO, at various temperature ranges, and a self-production protective film are finally formed. Oxygen permeates through a protective layer with much reduced diffusion coefficient.
