The delay time of the maximal intensity of the electric fields, zonal flows, and turbulence with respect to the sawtooth crashes is estimated as ∼ 1 ms and comparable to that of the sawtooth-triggered I-phases. Not only the zonal flows but also the radial electric fields lag behind the turbulence. Furthermore, the intensities lắp mạng viettel tại tphcm of both the zonal flows and electric field nearly linearly increase/decrease with the increase/decrease of the turbulence intensity. A double source predator-prey model analysis suggests that a relatively strong turbulence source may contribute to the dominant zonal flow formation during sawtooth cycles.
We report a new methodology in bulk MgB2 ring production for use in small-scale magnetic shielding or bench-top NMR systems. This process is a modified field-assisted sintering technique which enables direct formation of the rings without the need for machining or additives into the precursor powder. The shielding and trapped field capabilities of three mFAST MgB2 rings were determined using zero-field- and field-cooled magnetic experiments. Individual bulks trap magnetic fields up to 1.24T at 20K comparable to the highest published data for a ring sample. It is anticipated that for many applications, multiple rings will be stacked to form the required experimental structure. We find for the three ring stack a trapped field of 2.04T and a maximum shielded field of 1.74T at 20K.
The goal is not to create an “A-Z” map in which each value driver can be fully traced. This work can help you clarify why certain decisions were made, where traceability gets tenuous, and spotlight when leaders are making educated guesses on the promise of digital investments. When asked on the challenges leaders face in framing tech value, the inability to link tech investment to growth, an over-index on ROI over long-term value measures, and fragmented reporting across business and technology groups, rose to the top.
With an annual pomelo production of 800,000 tons, the isolation of naringin from the pomelo peel is an interest attracting research. Besides ripe ponelo peel, very immature pomelo discarded during the cultivation can also be considered as a potential source of raw materials for the isolation of naringin from peels because naringin exhibits diverse biological activities. The results of RP-HPLC-UV analysis on naringin, isolated from the peel of pomelo, showed that the naringin content in the pomelo peel, the isolation yield, and the chemical purity decreased with the maturity of pomelo. Particularly, the study found that the chemical purity (% naringin) of very immature pomelo peels (from 7-15 days old) possessed naringin products containing up to 92.3%, while % naringin products isolated from ripe pomelo peels contained only 53.3%.
MgB2 is a promising material for intermediate temperature applications where conventional low temperature superconductors cannot be used, especially if the range of magnetic fields over which is has acceptable current carrying performance can be expanded. However, its applicability is limited by poor properties at elevated magnetic fields. Carbon-based dopants can be timesofworld used to dramatically improve the high-field performance of MgB2, but at the cost of a reduction in the superconducting transition temperature that limits the operation temperature to 20 K or below. Here we report an enhancement of superconducting performance of MgB2 with the addition of cubic and hexagonal boron nitride , without any significant reduction in Tc.

Petunia seeds were obtained from flower seeds grown in natural conditions at Da Lat city. Petunia seed samples were irradiated at doses of 1, 2, 3, 4, 5, 6 or 7 Gy to evaluate the ability to stimulate the germination and as well as at the high doses of tool kéo mem telegram 100, 200, 300, 400 or 500 Gy to determine the LD50 value. The results showed that at the dose of 2 Gy, the germination rate reached more than 80% of the seeds, approximately 4 times higher than that of the control sample and the LD50 value was 126 Gy.
Human uterine tissue fragments were collected and mechanically damaged for in vitro modeling. The fibrin scaffolds were fabricated and combined with, respectively, human adipose tissue stem cells and human bone marrow stem cells to be treated in an established injured model in conditions with or without estrogen. Histological assessments were performed to compare and confirm the regenerative effect of the treatments after 14 days of investigation.
HTS CCs are characterized by an extremely large width-to-thickness ratio of the superconducting layer, normally up to 1000 ∼ 6000, which in general leads to a very large number of degrees of freedom. The magnetic vector potential A is used to calculate the magnetic field distribution in all simulated domains. The current vector potential T is used to calculate the current density in the superconducting layer, which is a material simulated with a highly nonlinear power-law resistivity. Then, the literature on the implementation of T-A formulation for simulating applications ranging from simple tape assemblies to high field magnets is reviewed.
Because more than 86% of the arguments in the biomedical domain significantly differed from those in the general domain, this proposed corpus was labeled on top of 317 labeled sentences from PASBio, the argument frameset specifically designed for the Biomedical domain. From these sentences, the proposed từ thiện, gây quỹ semi-automatic solution additionally generated 87 sentences which were manually annotated by our experts. More instances were further generated by using the virtual example method, a powerful and flexible data augmentation technique that has been successfully applied in a wide range of tasks.
Many traditional methods have been used to increase the germination such as selecting the optimal conditions of the medium such as temperature, pressure, humidity, or chemical treatment. Nowadays, the X-ray irradiation is used to the germinating stimulation and mutation studies. Some advantages of using a X-ray generator tra cứu luật as the source irradiation are easily changing the emitted energy, the dose and dose rate as well as when not in use it is not neccesary to shield the the apparatus. In this study, a X-ray generator MBR-1618R-BE was used with the emission energy of 160 keV and the irradiated dose would be changed from 1 Gy to 1500 Gy.
