Analysis of the air gap magnetic field in cylindrical magnetic couplings based on mathematical and finite element approach.

The air gap magnetic field of a magnetic coupling plays a crucial role in the examination of its static torque and eddy current losses. Precise characterization of the air gap magnetic field is essential for ensuring the accuracy of performance assessments of the magnetic coupling. This study focuses on the cylindrical magnetic coupling as the subject of investigation, employing mathematical analysis and finite element methods to evaluate and quantify the magnetic field properties.

Comparative study on ignition delay time and burning rate of modified double-base propellant and fuel-rich propellant.

With the higher requirements of various tactical and technical indicators of the weapon systems, the current research on the ignition and combustion characteristics of different types of solid propellants is not comprehensive. In more complex and harsh environmental conditions, the pressure affects the ignition and combustion characteristics. Therefore, the paper studies the ignition and combustion characteristics of the modified double-base propellants (MDB propellants) and fuel-rich propellants (FR propellants) under low-pressure environment.

[Electroacupuncture at "Zusanli"(ST36) and "Xuanzhong"(GB39) improves inflammatory reactions and reduces levels of serum MMP-3 and MMP-9 in adjuvant arthritis rats].

Objective: To observe the effect of electroacupuncture (EA) at "Zusanli" (ST36) and "Xuanzhong" (GB39) on joint inflammatory reactions and serum matrix metalloproteinase-3 (MMP-3) and MMP-9 contents in rats with adjuvant arthritis (AA), so as to explore its mechanism underlying improvement of AA.

Methods: Forty male SD rats were randomly divided into control, model, acupoint and non-acupoint groups (=10 in each group). The arthritis model was established by hypodermic injection of complete Freund's adjuvant (0.

[Effects of Electroacupuncture on Joint Function in Rheumatoid Arthritis Patients of Liver- and Kidney- Deficiency Type].

Objective: To compare the effects between electroacupuncture (EA) plus western medicine and simple western medicine in improving clinical symptoms and local joint function of rheumatoid arthritis (RA) patients with deficiency of Liver and Kidney.

Methods: A total of 68 RA patients of deficiency of Liver and Kidney were equally randomized into EA+medication group and medication group (=34 in each group). Both groups were given once-a-week methotrexate (7.

Electroacupuncture attenuates collagen-induced arthritis in rats through vasoactive intestinal peptide signalling-dependent re-establishment of the regulatory T cell/T-helper 17 cell balance.

Objective: Imbalance between T-helper 17 (Th17) cells and regulatory T (Treg) cells is causally linked to the development of rheumatoid arthritis (RA). In this study, we tested the hypothesis that electroacupuncture (EA) confers therapeutic benefits in RA through activation of vasoactive intestinal peptide (VIP)-dependent signalling and restoration of the Th17/Treg cell balance.

Materials And Methods: A collagen-induced arthritis (CIA) model was induced in Sprague-Dawley rats by injection of bovine type II collagen in incomplete Freund's adjuvant on day 0 and day 7.

Electroacupuncture inhibits inflammation reaction by upregulating vasoactive intestinal Peptide in rats with adjuvant-induced arthritis.

Acupuncture is emerging as an alternative therapy for rheumatoid arthritis (RA). However, the molecular mechanism underlying this beneficial effect of acupuncture has not been fully understood. Here, we demonstrated that electroacupuncture at acupoints Zusanli (ST36), Xuanzhong (GB39); and Shenshu (BL23) markedly decreased the paw swelling and the histologic scores of inflammation in the synovial tissue, and reduced the body weight loss in an adjuvant-induced arthritis rat model.

[Effects of acupuncture on the number and degranulation ratio of mast cells and expression of tryptase in synovium of rats with adjuvant arthritis].

Objective: To observe the effects of acupuncture on synovial pathology, synovial mast cell degranulation and tryptase expression and to investigate the relationship between the functions of mast cells and effects of acupuncture on early adjuvant arthritis in rats.

Methods: Forty-six male Wistar rats were randomly divided into normal control group (n=16), untreated group (n=15) and acupuncture group (n=15). Adjuvant arthritis was induced by injection of 0.
