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...

A detailed account of mouse neurulation is given based mostly on SEM analysis over 20 hr of development. Many observations and measurements were made on staged living embryos and on embryos prepared for scanning and light microscopy to help deduce what mechanisms may contribute to neural tube formation. Each lateral half of the early cephalic neural plate makes a convex bulge, opposite to the w...

We conducted microstructural and microchemical analyses of deformation bands in a forearc fold belt consisting the Eocene Urahoro Group located northern Japan. In study area, there was one flexure (or monocline) developed where pervasively occurred arkosic sandstone intercalated with mudstone coal layers. Deformation formed at maximum burial depth c. 1.5–2.5 km; this inferred from both thicknes...

purpose: to report a young patient with microphthalmos associated with bilateral papillomacular fold and severe hyperopia case report: in this observational case report, a sixteen-year-old young man was referred with high hyperopia to al-zahra eye hospital, zahedan university of medicalf sciences, zahedan, iran, for check up. spherical error in right eye (re) was +14.75 d and in the left eye (l...

The contents of the small intestine are fluid in character, travel rapidly through the 22 feet of its length, and begin to issue through the ileo-csecal valve within four to five hours of a meal. They travel through the large intestine far more slowly, reaching the hepatic flexure in six and a half hours, the splenic flexure in nine hours, and the pelvic colon in about eighteen hours?in a semi-...

This paper describes the design of a small-scale three degree-of-freedom compliant-mechanismbased manipulator with an approximately 2cm x 2cm x 2cm cubic workspace. The manipulator exhibits a significantly larger range of motion and better spatial structural properties than a conventional compliant mechanism, due primarily to a unique flexure joint developed by the authors. A brief description ...

This paper presents a controller design to compensate the effects of time delay in a flexure-based piezoelectric stack driven nanopositioner. The effects of the time delay in flexure nanopositioners is illustrated and identified by means of experimentally obtaining the frequency response of the system. Moreover, a theoretical model which takes into account the dependence between the sampling ti...

The evidence is accumulating that dinucleotide steps other than AA/TT affect DNA flexure of AnTm (m + n greater than = 4) containing fragments. However, it is not clear whether macroscopic DNA flexure without AA/TT steps might occur. In this paper we demonstrate the anomaly in electrophoretic mobility of non AA/TT repetitive DNA sequences which is a function of sequence phasing. Therefore, our ...

Si3N4/BN fibrous monoliths were prepared with 4 wt% Y2O3 added as a sintering aid to the Si3N4. Residual carbon, present in the billet before hot-pressing, was shown to influence the final microstructure. The sintering aid glass, known to migrate into the BN cell boundaries during hotpressing, was not sufficient in quantity to prevent premature shear failure when samples were tested in flexure....
