During the perimenopausal and early postmenopausal periods, women experience several systemic psychological changes. They mainly concern genitourinary, central nervous, musculoskeletal, cardiovascular systems. Changes related to aging process of skin also play an important role. The aim study was evaluate influence age, selected anthropometric data (such as body weight, height, mass index (BMI)...
We describe an algorithm for the numerical solution of a phase-field model (PFM) of microstructure evolution in polycrystalline materials. The PFM system of equations includes a local order parameter, a quaternion representation of local orientation and a species composition parameter. The algorithm is based on the implicit integration of a semidiscretization of the PFM system using a backward ...
The relationship between protein sequence and structure arises entirely from amino acid physical properties. An alternative method is therefore proposed to identify homologs in which residue equivalence is based exclusively on the pairwise physical property similarities of sequences. This approach, the property factor method (PFM), is entirely different from those in current use. A comparison i...
Abstract When used as trapped field magnets (TFMs), single grain, bulk high-temperature superconducting (HTS) rings are promising candidates for the generation of strong, uniform magnetic fields nuclear resonance. The pulsed magnetisation (PFM) technique provides a low cost, compact and portable method to magnetise these samples TFMs; however it has proven difficult achieve high in HTS using PF...
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...
