Introduction: Angle and internal position of lateral pterygoid muscle leads to contraction over two half of the mandible in maximum opening and protrusion position so it can affects impression prosthetic procedures. The aim of this study was to evaluate the mandibular flexure in two transverse and antro-posterior dimensions. Methods: Seventy edentulous patients at Mashhad Faculty of Dentistry a...

in this work, new biodegradable abcba type pentablock copolymers with different mole ratio of l-lactide and ppdo-b-peg-b-ppdo triblock copolymer were synthesized and characterized. in the first step, ppdo-b-peg-b-ppdo triblock copolymer was synthesized via a ring-opening polymerization of p-dioxanone (pdo) monomer with poly (ethylene glycol) (peg) using stannous octoate (sn(oct)2) as the cataly...

Tujuan penelitian ini adalah untuk mengetahui pengaruh bukaan (web opening) terhadap perilaku struktur, konfigurasi penulangan, dan mekanik pada balok tinggi menggunakan Metode Strut-and-Tie. Model yang digunakan berperletakan sederhana dengan panjang 6 m 2 m. Variasi pemodelan diterapkan posisi yaitu daerah geser lentur. Hasil dari penelitiaan menunjukan menyebabkan peningkatan struktur cukup ...

Arthropods include a high diversity of lineages adapted for silk production. Several species microscopic phytophagous mites the hyperdiverse superfamily Eriophyoidea spin web; however, origin their is unknown. We described new web-spinning mite, Aberoptus schotiae n. sp., collected from leaves Schotia brachypetala (Fabaceae) in South Africa and showed that it has complex life cycle, including t...

• A finite element model of composite cellular beams with PCHCS was developed. parametric study carried out by geometrical non-linear analyses. Symmetric and asymmetric section were considered. The predominant failure mode the web post buckling. strength not limited only beam. This paper aims to predict ultimate behavior steel–concrete using precast hollow core slabs. is developed analysis. out...

In this research, effect of opening on the buckling of FMLs (Fiber Metal Laminate) is studied. Samples are made of a laminate, epoxy resin reinforced with four layers of woven basalt fibers, inserted between two Al plates. Different samples are prepared, tested and studied; one group without opening and the other two groups with circular openings of radii 10 and 20 mm. In all samples buckling i...

introduction: temporomandibular disorders (tmd) lead to masticatory muscle pain, jaw movement disability and limitation in mouth opening. pain is the chief complaint in 90% of the tmd patients which leads to disability and severe socioeconomic costs. the purpose of this study was to evaluate the therapeutic effects of low level laser therapy (lllt) compared to pharmacotherapy with nsaids (napro...
