During the composition of a piece of music, composers often focus on the crafting of melody and harmonic lines rather than a percussive track that may accompany them. For amateur composers, creating a drum track by hand can be both tedious and frustrating, due to their lack of skill and experience with the task. In recent years, computer software tools have been created to help automate the cre...
Sampling of platelets for trace-element analysis poses special problems: obtaining adequate sample material, achieving a sufficient cell purity, preserving viability (integrity), correcting for trapped plasma, and controlling contamination. We used a blood-cell separator for the primary isolation of platelets from blood, and differential centrifugation in natural plasma to further isolate them....
The concept of hyperbolic flux tubes (HFTs) is a generalization of the concept of separator field lines for coronal magnetic fields with a trivial magnetic topology. An effective mechanism of a current layer formation in HFTs is proposed. This mechanism is called magnetic pinching and it is caused by large-scale shearing motions applied to the photospheric feet of HFTs in a way as if trying to ...
We have studied the hybridization of target DNA in solution with probe DNA on magnetic beads immobilized on the channel sidewalls in a magnetic bead separator. The hybridization is carried out under a liquid flow and is diffusion limited. Two systems are compared: one with a straight microfluidic channel and one with an integrated staggered herringbone mixer. Fluorescence microscopy studies sho...
A sustainable, heat-resistant and flame-retardant cellulose-based composite nonwoven has been successfully fabricated and explored its potential application for promising separator of high-performance lithium ion battery. It was demonstrated that this flame-retardant cellulose-based composite separator possessed good flame retardancy, superior heat tolerance and proper mechanical strength. As c...
This work aims to study the possibility of using an electrostatic drum-type separator prepare a powder with narrow size distribution curve for usage in additive manufacturing. The distributions uncoated commercial aluminum powders ASP-30, ASP-22, and ASP-5 were analyzed. It was shown that ASP-30 ASP-22 have similar asymmetric SPAN 1.480 1.756, respectively. powder, turn, has 0.869. chosen furth...
The X-ray corona is richly structured with individual plasma loops. A model is presented explaining these loops as the sites of magnetic energy storage and sporadic release. Energy is stored as coronal currents driven inductively by motions at the photosphere. These currents occur at internal boundaries in the coronal eld called separator. A method is described for completely characterizing the...
Lake Qinghai is the largest lake in China and situated in an important climate-sensitive zone on the northeastern margin of the Tibetan Plateau, making it an ideal place to study the environmental evolution of the northwest China as well as the interplay between the Asian monsoon and the westerlies in the late Quaternary. In this study, detailed rock magnetic measurements were carried out on th...
