In this work, the NdFeB permanent magnets, with chemical compositions as followed (at %): Nd: 6.7-14, Fe: 66-80, B: 6-14, Al: <1-4, Pr: <1-3, Dy: <1-8, Tb: <0.5-3, has excellent magnetic properties [14, 15], and the maximum energy products (BH), intrinsic coercivity (Hci), remanence (Br), and coercivity (Hc) of the magnets were 278-318 KJ·m-3, 870-2500 KA·m-1, 1.1-1.4 T, 840-2390 KA·m-1, respectively.
The EDX analysis indicated that the formed a weak contrast Nd-rich phase, marked as point ‘‘1’’, ‘‘3’’, ‘‘5’’, ‘‘6’’, ‘‘8’’, was rich in Fe, Nd, Pr, and Al.

According to the findings of Bank et al. [8], the design of connections is the most crucial factor in the overall design process.

Some of the researchers that studied the problems under the assumption that the release dates are all zero include: Chen et al. [7] considered the problem of scheduling n jobs with different due dates on a single machine in order to minimize the weighted sum of earliness and tardiness.
Also, the following researchers studied the problem under the common due date assumption: Panwalker et al. [13] considered the scheduling problem of minimizing total penalty on a single machine with a common (but unknown) due date.
Lin et al. [16] studied a class of single-machine scheduling problems with a common due date where the objective is to minimize the total earliness–tardiness penalty for the jobs.
(2) also the earliness of each job is defined as: Ei = max {(di - Ci ), 0} (3) and the tardiness of each job is defined as Ti = max {( Ci - di ), 0} (4) The total earliness is defined as (5) The total tardiness is defined as (6) Therefore, using the notations of Graham et al. [18], the problem being considered is represented as Thus the linear composite objective function is defined as (7) α + β = 1 (8) Where α = relative weight of the total earliness criterion and β = relative weight of the total tardiness It is assumed that pre-emption is not allowed and that the problem is static and deterministic, i.e. number of jobs, their processing times, and ready times and due dates are all known and fixed.

The first example for the preparation of regularly spaced nano channels in a glassy polymer matrix had been reported by Hashimoto et al [24].
Fig. 7: Silicates with: (A) spherical pores of cubic order; (B) hexagonally ordered cylindrical pores; (C) lamellar pores, prepared from lyotropic phases of block copolymers [5, 8] Liu and et al [26] used a triblock copolymer polyisopren-blockpoly (2-cinnamoylethyl methacrylate) -block-poly (tert-butylacrylate) (ABC) to produce a membrane with ordered nano-channels by.
Hillmyer et al. had found that polystyren-block-polylactide (PSt-b-PL) copolymers can form hexagonally packed nanocylinders of PL in PSt which can then be converted into pores by selective hydrolysis of the PL (Figure 8 [27], [28]).
Mayes et al showed a promising example for such a transfer of microphase-separated morphologies of well-defined block copolymers into a ‘real-world’ separation membrane [34].

The sequencing was performed following the method of Sanger et al. [9],
using an ABI PRISM 310 Genetic Analyzer.
The purified band appears with higher molecular weight than the expected, a phenomenon observed previously by McPherson et al. [24].
Reguera et al. [20] demonstrated that there is a linear decrease in Tt versus the salt concentration (NaCl), which is in agreement with our data.
This fact provides an answer to the increasing values of enthalpy (Table 2) as the NaCl concentration raises and was previously observed by Reguera et al. [20].

After the distillation process, a heavier product is obtained, known as bitumen (Antunes et al., 2015).
When crude oil is heavier, bitumen yields tend to be higher (Porto et al., 2019).
For example, a study found that Polyphosphoric acid (PPA) was defined to be a means of stabilizing PMBs in their formulations (Giavarini et al., 1996).
Silicon tetrachloride is pyrolyzed in a flame, or quartz sand is vaporized in a 3000°C electric arc to produce fumed silica (Gagne et al. 2005).

The nucleic acid separation process was conducted using magnetic beads in the RT-PCR system developed by Comman et al. [8].
Setyawan et al found that superparamagnetic properties of magnetic bead of 20 emu/g were improved by adding silica as its coating material [14].
