In addition, these factors are still not much understood, which leads to studies being done more on understanding these factors rather than remedying the laboratory testing procedure in the past several years (
FCM attains the segmentation by an iterative procedure [6,8,22–27] which minimizes the objective function: (1)J=∑k=1n∑i=1cuikxk−vi2m where uik defines the membership of the pixel xk in the ith cluster, vi is the ith cluster center, n is the number of pixels, m is the fuzz...
1a). Embryos were collected in 1 h period on a grape juice plate (diameter 63 mm) smeared with yeast paste. The first-hour collection served as an egg cleanup procedure for the female flies and these eggs were abandoned. Disturbance of flies was minimized during embryo collection. Grape...
The microscope was then turned on to monitor the fluid flow in the micromodel. Water was then injected through the inlet port of the micromodel. The whole procedure was also videotaped. (4) The microscope was used to observe distribution of oil and water in glass etching model. When the ...
All of these methods require expensive instruments and sample cleanup procedure. To overcome the deficiency of traditional methods, QuEChERS procedure was developed to extract pesticides from fruits and vegetables. In the present research work, original QuEChERS extraction approach was modified for investiga...
Figure 4 represents the differentiation procedure, which lasted a maximum of 30 days. First, immature neurons were derived for 7–10 days in the presence of neurotrophic factors NGFβ and BDNF (basic neuronal medium). Second, dopaminergic phenotype was induced by additional Shh and FGF8b ...
3 Experiment 2: Prince implemented in a multi-task experiment Experiment 2 contrasts with Experiment 1 in showing how Prince can be used when there are many measurements, even though Prince implements only one choice for real. 3.1 General procedure N = 80 subjects (41.2% female) recruited...
The samples of stele and cortex tissue were re-analysed together with their corresponding blanks, using the optimised procedure (Figs. 2 and 3). In particular the Mn-signals had been significantly reduced from > 120,000 counts on the PEN membranes (Additional file 1) to a couple of hun...
In that case, the identification of material parameters with the VFM is based on an iterative procedure that consists in minimising the gap to equilibrium, which is achieved when the PVW is fulfilled. Some studies have demonstrated that elastoplastic behaviour models with non-linear isotropic ...
In more detail, the a) part includes the following actions: Subsequently, part b) consists of the following analyses: All the method steps are described in the following sub-sections. 2.1. Spectral measurements - instrumentation and procedure – Step a.1 Measurements of spectral irradiance were ...
