Study of Stability and Vibration Reduction in Multi-Tool Ultrasonic Machining under Simultaneous Primary and Internal Resonance

引用

Applied Mathematics 2012年第1期3卷 1-11页

作者： Yaser Salah Hamed Mohamed syed abd Elkader Hamdi Mahmoud Genedi 不详

The main object of this paper is the mathematical study of the vibration behavior in ultrasonic machining (USM) described by non-linear differential equations. The ultrasonic machining (USM) consists of the tool holder and the absor-bers representing the tools. This leads to four-degree-of-freedom system subject to multi-external excitation forces. The aim of this project is the reduction of the vibrations in the tool holder and have reasonable amplitudes for the tools represented by the multi-absorbers. Multiple scale perturbation method is applied to obtain the solution up to the second order approximation and to study the stability of the steady state solution near different simultaneous resonance cases. The resulting different resonance cases are reported and studied numerically. The stability of the steady state solution near the selected resonance cases is studied applying both frequency response equations and phase-plane technique. The effects of the different parameters of the system and the absorbers on the system behavior are studied numerically. Optimum working conditions for the tools were obtained. Comparison with the available published work is reported.

Assessment of Sub-Endometrial Junction Zone by 3-Dimensional Transvaginal Ultrasound in Unexplained Recurrent Implantation Failure and Its Effect on ICSI Outcomes

引用

Open Journal of Obstetrics and Gynecology 2019年第1期9卷 54-61页

BACKGROUND: Sub-endometrial junction zone (JZ) plays an important role in most of reproductive functions. OBJECTIVE: To find out the effect of the sub-endometrial JZ thickness assessment by 3-D trans-vaginal ultrasound (TVUS) on intracytoplasmic sperm injection (ICSI) outcomes in patients with unexplained recurrent implantation failure (RIF). SETTING: ART Unit of Obstetrics and Gynecology Department, Faculty of Medicine, South Valley University, Qena, Egypt. DURATION: From April 2016 to October 2018. STUDY DESIGN: A prospective observational study. METHDS: Fifty couples with history of unexplained RIF in previous ICSI cycles and prepared for another ICSI cycle (group I) and fifty couples with unexplained infertility prepared for ICSI for the first time (group II) had been included in this study. At time of ovum pick up, 3-DTVUS was done for all cases in both groups for assessment of sub endometrial junction zone thickness and correlated with ICSI outcome. RESULTS: There were statistically significant differences between group I and group II in JZ thickness in the 3 uterine regions (fundus, anterior and posterior walls) with p 0.001, but there were mildly statistically significant differences between both groups in chemical and clinical pregnancy rates with p < 0.01. CONCLUSIONS: The thickness of JZ in patients with history of unexplained RIF was higher than those with unexplained infertility scheduled for ICSI. The JZ thickness was inversely correlated with increased embryo implantation rates in ICSI procedures, the thinner the JZ thickness was associated with higher pregnancy rates (both chemical and clinical pregnancy rates).

Numbers of 300 day-old broiler chickens through a CRD design with 5 treatments, 3 replicates and 20 chicks in each pen were used to evaluate the effect of thyme (T), licorice (L), thyme + licorice (TL), and enzyme supplemented (E) diets on performance, immune and carcass characteristics. According to the results, performance traits, immune indices, and carcass traits in herbal medicine and enzyme supplemented diets were improved significantly than control diet (P abdominal fat and liver weight as indicators of lipogenesis rate were decreased in T, L, and TL diets than control or E diet significantly (P < 0.05). Immune organs such as burse and spleen weight as indicators of immune situation were increased in TL diet than other treatments significantly (P < 0.05). These findings indicated that thyme and licorice singly or in combination as organic herbal medicine can affect performance, carcass and immune characteristics. Also an improved immune organ such as burse or spleen in this study indicates that this herbal medicine can promote the immune situation and efficacy of health and livability.
