BACKGROUND The measurements of body mass index (BMI) and percentage of body fat are used in many clinical situations. However, special tools are required to measure body fat. Many formulas are proposed for estimation but these use constant coefficients of age. Age spectrum might affect the predicted value of the body composition due to body component alterations, and the coefficient of age for ...

statement of problem: recent clinical results for zirconia all-ceramic restorations have revealed that the fracture rate 6-15% of the zirconia framework is so low and the core of zirconia has high stability. however, chipping-off fractures of porcelain are the most common reason for failures of zirconia in the fixed partial dentures. objectives: the purpose of this study was to compare the shea...

In this clinical report, we discuss the length of service and subsequent replacement of a maxillary anterior 2-unit cantilever fixed partial denture (FPD). The FPD provided 53 years of service to the patient and was finally replaced with a 2-unit porcelain-fused-to-metal (PFM) FPD. The original prosthesis replaced a missing maxillary lateral incisor using a partial coverage metal retainer, wher...

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...

LLC resonant DC-DC converter has been widely used in high power density and efficiency applications. Pulse frequency modulation (PFM) is commonly applied due to its wide soft-switching range. In some special cases, phase shift (PSM) widen voltage regulation range, improve light-load efficiency, or implement a soft start-up process. Because with 2 control degrees of freedom (2DOFs), switching du...

Panicum coloratum var. is a subtropical grass for potentially increasing forage production in lowly productive environments where cattle-raising activities have been relocated. Heritability was estimated characters related to salinity tolerance under saline and non-saline conditions explore the possibility of improving by selection. From base germplasm collected very harsh environment, heritabi...
