A female presented to the office with a chief complaint concerning the esthetics of the porcelain-fused-to-metal (PFM) crowns on her maxillary lateral incisors. The objective was to use contemporary materials and techniques to have them blend better with her natural dentition. The PFM crowns had been completed at different times during her life. She said they did not match each other or her adj...

Polar tweed was discovered in mechanically stressed LaAlO3. Local patches of strained material (diameter ca. 5 μm) form interwoven patterns seen in birefringence images, Piezo-Force Microscopy (PFM) and Resonant Piezoelectric Spectroscopy (RPS). PFM and RPS observations prove unequivocally that electrical polarity exists inside the tweed patterns of LaAlO3. The local piezoelectric effect varies...

‘Identifying the conditions that favour successful PFM reform is a good start, but we need to understand the possibilities when not all of these conditions are present.’ Following more than a decade of intensive activity, the debate on public financial management (PFM) reform in developing and transition countries seems settled. The main elements of technical good practice are clear and the cri...

An atlcmpl was made for an cx:pcrimcntal test on PFM. Some results of the experimental test show that almost distortion free information recovery, from the frequency modulated pulse train, is possible by low-pass ...

Hypothesis / aims of study Studies report that whole-body vibration (WBV) recruits about 95-97% of the muscle fibers, due to the oscillations generated by the vibrating platform, which can enable both surface and deep muscles. Lauper (2009) reports that the active vibration the muscles of the pelvic floor (PFM) which may improve your reflex stimulation and synergistic [1,2]. The objective of th...

In a modern power system, to realize the safe operation of units and maintain frequency stability network, various means modulation can be adopted. However, there are some deficiencies in real-time monitoring assessment management primary (PFM). To solve these problems, PFM online method based on “master–sub” control station model wide area measurement system (WAMS) is proposed as strategy supp...

Complementary Metal-Oxide Semiconductor (CMOS) image sensor is the dominant electronic imaging device in many application fields, including the mobile or portable devices, teleconference cameras, surveillance and medical imaging sensors. Wide dynamic range (WDR) imaging is of interest particular, demonstrating a large-contrast imaging range of the sensor. As of today, different approaches have ...

BACKGROUND Current measurement tools have difficulty identifying the automatic physiologic processes maintaining continence, and many questions still remain about pelvic floor muscle (PFM) function during automatic events. OBJECTIVE To perform a feasibility study to characterise the displacement, velocity, and acceleration of the PFM and the urethra during a cough. DESIGN, SETTING, AND PART...

A new configuration of the passive fluxmeter (PFM) is presented that provides for simultaneous measurements of both the magnitude and the direction of ambient groundwater specific discharge qo and Cr(VI) mass flux J(Cr). The PFM is configured as a cylindrical unit with an interior divided into a center section and three outer sectors, each packed with a granular anion exchange resin having high...

OBJECTIVES The aim of this study is to evaluate the usefulness of Magnetic Resonance Imaging (MRI) at 20° of knee flexion in patients with patellofemoral pain syndrome (PFPS) caused by suspected patellofemoral malalignment (PFM). MATERIAL AND METHOD Fifty MRIs were performed on 25 patients with PFPS secondary to suspected PFM based on clinical examination, and on 25 patients without PFPS (con...
