引用

Open Journal of Obstetrics and Gynecology 2018年第11期8卷 1071-1083页

作者： waleed m. Khalaf mohamed Elmandouh mohamed Ibrahim Sarah Safwat Department of Obstetrics and Gynecology Faculty of Medicine Ain Shams University Cairo Egypt

Background: Cesarean section (CS), one of the most common major operative procedures, performed all over the world. Incisional infiltration with local anesthetics is a simple, cheap and effective mean of providing good analgesia for surgical operations without any major side effects & allowing early patients’ mobilization & postoperative recovery, so the purpose of study is to compare between the effect of wound infiltration with bupivacaine versus pethidine for post cesarean section pain relief. Patients and methods: A randomized controlled trial (RCT) was conducted in Ain Shams University maternity hospital in the period from August 2016 and January 2017. 100 full term pregnant females randomized into two groups: Group A (50 patients) Bupivacaine group: Subcutaneous and subrectal infiltration with 10 ml 0.25% Bupivacaine (2.5 mg/ml) diluted in 10 ml normal saline before closure of the wound was done;Group B (50 patients) Pethidine group: Subcutaneous and subrectal infiltration with 1 ml pethidine (50 mg/ml) diluted in 19 ml normal saline before closure of the wound was done. all patients had cesarean section under spinal anesthesia. Study outcome measures post-operative pain scores using visual analogue scale, post-operative analgesia requirement time to first rescue analgesia, onset of mobilization, side effect of local anesthetic, wound infection (after one week). It was registered on clinical *** with ID: NCT03652116. Results: Visual analogue scale values differ significantly between pethidine group and that of bupivacaine at rest and on coughing at 4, 8, 12, 24 hours & analgesic consumption (P value st time request analgesia per minute comparing group A to group B (P value 0.001). There is no significant difference between bupivacaine and pethidine regarding time of ambulation, side effects or complications. Conclusion: Infiltration of the wound of cesarean section with pethidine gives effective analgesia for several hours as compared to Bupivacaine.

Study on friction performance and mechanism of slipper pair under different paired materials in high-pressure axial piston pump

引用

Friction 2020年第5期8卷 957-969页

作者： Huaichao WU Limei ZHAO Siliang ni Yongyong HE School of mechanical Engineering Guizhou UniversityGuiyang 550025China State Key Laboratory of Tribology Tsinghua UniversityBeijing 100084China

High-pressure axial piston pumps operate in high-speed and high-pressure environments. The contact state of the slipper against the swashplate can easily change from an oil film lubrication to a mixed oil film/asperity contact, or even dry friction. To improve the dry friction performance of slipper pairs and to avoid their potentially rapid failure, this study examined the effects of material matching on the dry friction performance of the slipper pair for high-pressure axial piston pumps. A FAIAX6 friction and wear tester was developed, and the dry friction coefficients of the slipper pairs matched with different materials were studied using this tester. Based on the thermo-mechanical coupling of the slipper pair with the working process, the contact surface temperatures of the slipper pairs matched with different materials were calculated and analyzed for the same working conditions. Following this, the effects of the material properties on the temperature increase at the slipper sliding contact surfaces were revealed. The reliabilities of the temperature calculations and analysis results were verified through orthogonal tests of slipper pairs matched with different materials. The results indicate that the influence of the material density on the friction coefficient is greater than that of the Poisson's ratio or the elastic modulus, and that the slipper material chosen should have a high thermal conductivity, low density, and low specific heat, whereas the swashplate material should be high in specific heat, density, and thermal conductivity;in addition, the slipper pair should be a type of hard material to match the type of soft material applied;that is, the hardness of the swashplate material should be greater than that of the slipper material.

World Journal of Diabetes 2017年第4期8卷 165-171页

作者： Thomas T H Wan Amanda Terry Bobbie mcKee waleed Kattan College of Health and Public Affairs University of Central Florida Florida Hospital Creation Health Research Center

AIm To review impacts of interventions involving self-management education, health coaching, and motivational interviewing for type 2 diabetes. mETHODS A thorough review of the scientific literature on diabetes care and management was executed by a research team. RESULTS This article summarizes important findings in regard to the validity of developing a comprehensive behavioral system as a framework for empirical investigation. The behavioral system framework consists of patients' knowledge(K), motivation(m), attitude(A), and practice(P) as predictor variables for diabetes care outcomes(O). Care management strategies or health education programs serve as the intervention variable that directly influences K, m, A, and P and then indirectly affects the variability in patient care outcomes of patients with type 2 diabetes. CONCLUSION This review contributes to the understanding of the KmAP-O framework and how it can guide the care management of patients with type 2 diabetes. It will allow the tailoring of interventions to be more effective through knowledge enhancement, increased motivation, attitudinal changes, and improved preventive practice to reduce the progression of type 2 diabetes and comorbidities. Furthermore, the use of health information technology for enhancing changes in KmAP and communications is advocated in health promotion and development.

Application of Nanocrystalline Lani_5-type Hydrogen Absorbing alloys in ni-mH_x Batteries

引用

Journal of Rare Earths 2004年第5期22卷 596-599页

作者： Jurczyk m Nowak m Institute of materials Science and Engineering Poznan University of Technology 60-965 Poznan PolandInstitute of Materials Science and Engineering Poznan University of Technology 60-965 Poznan Poland

The structure and electrochemical properties of nanocrystalline Lani_5-type alloys were studied. These materials were prepared by mechanical alloying (mA) followed by annealing. The properties of hydrogen host materials can be modified substantially by alloying to obtain the desired storage characteristics. It was found that the partial substitution of ni by al or mn in Lani_(5-x)m_x alloy leads to an increase in discharge capacity. The alloying elements such as al, mn and Co greatly improved the cycle life of Lani_5 material. For example, in the nanocrystalline Lani_(3.75)mn_(0.75)al_(0.25)Co_(0.25) powder, discharge capacity up to 258 mAh·g^(-1) was measured (at 40 mA·g^(-1) discharge current). Furthermore, the effect of the graphite coating on the structure of some nanocrystalline alloys and the electrodes characteristics were investigated. The mechanical coating with graphite effectively reduced the degradation rate of the studied electrode materials. The combination of a nanocrystalline Lani_5-type hydride electrodes and a nickel positive electrode to form a ni-mH battery, was successful.

In this study, concentrations of Cr, mn, ni, Cu, Zn, Cd and Pb were determined in road dusts collected from different locations in Dhaka to assess source, contamination status and health risk. Energy-dispersive X-ray fluorescence spectroscopy and energy-dispersive X-ray spectroscopy were used to determine Cr, mn, ni, Cu, Zn, Cd and Pb and their mean concentrations were 162.27 ± 29.46, 721.18 ± 180.14, 35.65 ± 12.55, 104.56 ± 128.33, 515.32 ± 321.90,BDL, and 342.82 ± 591.20 mg/kg, respectively. Among the heavy metals, highest concentrations of Cu, Zn and Pb were found at urban sites-7(municipal waste dumping) and 8(medical waste incineration). Highest concentration of Cr followed by Cu and Zn was found at site-5(Tejgaon, urban). Principal component analysis revealed that anthropogenic activities are the potential sources for Cr, ni, Cu, Zn and Pb while earth crust for mn. Pollution index and pollution load index results suggested that all the sites were contaminated and/or degraded by Cr, Cu, Zn and Pb except sites-9(urban), 10(sub-urban), 11(rural) while sites-7 and 8(urban) were extremely degraded. For noncarcinogenic health risk, hazard quotient values for dermal were higher compared to that of inhalation/ingestion. Though hazard index values were less than 1 at all the sites, these were at least one order of magnitude higher for children group than that of adult group, thus the children group may face more noncarcinogenic health risk at sites -7 and 8. Values of incremental lifetime cancer risk were from 10to 10showed no carcinogenic health risk by road dusts contaminated with the heavy metals.
