Dust-Lower-Hybrid Surface Waves in Classical and Degenerate Plasmas

Communications in Theoretical Physics 2013年第11期60卷 623-629页

The dispersion relation for general dust low frequency electrostatic surface waves propagating on an interface between a magnetized dusty plasma region and a vacuum is derived by using specular reflection boundary conditions both in classical and quantum regimes. The frequency limit ω ≤ωei ≤ ωce is considered and the dispersion relation for the Dust-Lower-Hybrid Surface Waves （DLHSW＇s） is derived for both classical and quantum plasma half-space and analyzed numerically. It is shown that the wave behavior changes as the quantum nature of the problem is considered.

High-throughput Three-dimensional Gel Electrophoresis for Versatile Utilities: A Stacked Slice-gel System for Separation and Reactions (4SR)

A novel high-throughput system, called the stacked slice-gel system for separation and reactions （4SR）, was developed for the analysis of DNA/RNA and protein/peptide. The system provides a novel three-dimensional gel electrophoresis approach that exploits the property of stacked slice gels. It allows multiple samples simultaneously to react as well as to be separated, offering a two-dimensional （m×n） sample loading system. For this purpose, high-throughput multi-micro vessels （mmVs） containing variable numbers of wells （100 wells in this paper） have been used, which are made of 25 mm square-size polyacrylamide gels. Furthermore, after electrophoretic separation, a slice gel containing a desired sample can be easily removed and proceeded to the next step. Different biological reactions as well as successive separation of products were effectively carried out dealing with DNA/RNA and protein/peptide. It shows that this system has a diversity of potentials to be developed.

Background: Posterior urethral injury usually occurs in male patients with pelvic fractures. Posterior urethral injuries are associated with considerable morbidity including urinary incontinence, erectile dysfunction and urethral stricture. Objective: To compare the outcomes between early primary endoscopic realignment and delayed reconstruction in the management of male patients of posterior urethral injury. methodology: This prospective study was conducted in the department of urology and department of casualty, Dhaka medical College Hospital, Dhaka, Bangladesh from July 2015 to June 2017 among 50 male patients with posterior urethral injury. Fifty patients were randomly allocated into two groups;the group A consisted of 24 patients underwent early primary endoscopic realignment within 10 days after posterior urethral injury and the group B consisted of 26 patients underwent delayed reconstruction in form of anastomotic urethroplasty after 3 months. All patients were followed up at 3rd, 6th and 9th month after the procedure. Outcome variables were post-operative urethral stricture, urinary incontinence and erectile dysfunction. Data were analyzed and compared by statistical tests. Results: The mean (±SD) age of the study patients was almost similar between the groups (28.8 ± 8.4 vs. 27.4 ± 7.2 years, p = 0.486). In group A, 83.33% patients developed postoperative urethral stricture, none of them developed urinary incontinence and 20.83% developed erectile dysfunction;On the other hand, in group B, these rates were 38.46%, 23.07% and 38.46% respectively. Postoperative urethral stricture formation was significantly higher in Group A (p = 0.0012) but urinary incontinence and erectile dysfunction rates were significantly higher in Group B (p = 0.018 and p = 0.042 respectively). Conclusion: Early primary endoscopic realignment is better than delayed reconstruction in the management of male patients with posterior urethral injury. It provides less postoperative complica
