INTRODUCTION: High-intensity focused electromagnetic field treatment (HIFEM) uses low-frequency waves to induce supramaximal muscle contractions, causing hypertrophy and reducing fat. OBJECTIVE: To evaluate the effects of a HIFEM for improvement cellulite on buttocks. METHODS: Thirty patients were divided into two groups that received eight or 12 sessions buttocks six weeks. We assessed in butto...

a new approach for analyzing cracked problems in 2d orthotropic materials using the well-known element free galerkin method and orthotropic enrichment functions is proposed. the element free galerkin method is a meshfree method which enables discontinuous problems to be modeled efficiently. in this study, element free galerkin is extrinsically enriched by the recently developed crack-tip orthot...

background: small photon fields are increasingly used in modern radiotherapy especially in intensity modulated radiation therapy (imrt) and stereotactic radiosurgery (srs) treatments. accurate beam profile and central axis depth doses measurements of such beams are complicated due to the electron disequilibrium. hence the ebt2 (external beam therapy) gafchromic film was used for dosimetry of sm...

Magnetic resonance (MR) is based on the principle that nuclei of elements with an odd number of protons and neutrons spin and behave as magnets. When they are placed in a strong magnetic field, these nuclei align themselves in relation to the field. Ifradiowaves with a frequency specific to the nucleus and strength of the magnetic field (resonant frequency) is applied, some of the nuclei will a...

DOR: 98.1000/2383-1251.1397.5.33.9.1.1578.1610 Extended abstract Introduction: Niger with the scientific name of Guizotia abyssinica (L.F.) Cass. belongs to the Asteraceae family. Niger seed contains 50-75 percentage of oil which is used in the treatment of rheumatism and burns, and as a substitute for olive oil. Its meal is also used for animal feeding. Environmental crises sustained by ...

BACKGROUND Slow crack growth can be described in a v (crack velocity) versus KI (stress intensity factor) diagram. Slow crack growth in ceramics is attributed to corrosion assisted stress at the crack tip or at any pre-existing defect in the ceramic. The combined effect of high stresses at the crack tip and the presence of water or body fluid molecules (reducing surface energy at the crack tip)...
