Comparative features of the dorsal tongue epithelia in musk shrews, mongooses and rats were described. The shapes filiform papillae different each species. distribution pattern was similar both shrews mongoose, that form changed gradually from lingual apex to posterior part body. By contrast, types distributed on definite areas surface rat. Microridges interpapillar shrew mongoose presented a clear outline, but those rat not so distinct. In all species, upper did show any distinct microridges.

Abstract Light and electron microscopic examination of the dorsal lingual epithelium beagle dogs ( Canis domesticus ) revealed three different regions: that anterior to filiform papillae, posterior an interpapillary region. Whereas basal suprabasal cells are similar throughout, differences characterize intermediate surface layers. Keratohyalin granules common in layers regions, tonofibrils prominent region, no keratohyalin occur. The layer region is not keratinized, shows soft...

Connective tissue papillae underlying epithelial cell layers of the lingual newborn mongrel dogs were exposed by long term hydrochloric acid treatment and observed scanning electron microscopy.Each filiform ovoid shape (100-130μm in diameter) contained a connective papilla representing smaller elliptical protrusion (90-100μm length, 70-80μm width). Its overview showed horse-shoe shape, opening anteriorly. posterior curvature projected conical node with rounded apex.Each fungiform (150μm...

Abstract The present study investigated a novel milling method for producing amorphous rice starch without adding water. A new type of machine was developed (termed the shear and heat (SHMM)), which is capable applying mechanical during process. SHMM consisted pair mortars attached to servomotor ring heater. heater installed on upper mortar; temperature mortar monitored controlled by thermal controller. Wide‐angle X‐ray diffraction (WAXD) analysis used determine crystallinities in flour...

It is known that conventional crystalline rice batter without gluten does not keep high void fraction after fermentation. In this study, the with amorphous flour provided a higher than flour. The of increased increasing content uniaxial elongational property did show strain hardening. On other hand, addition caused hardening behavior in measurement. When exceeded 60 wt%, we observed for batter.

The aim of the present study is to investigate local strain band behavior in conjunction with texture NiTi thin sheets under mechanical loading. Firstly, we evaluate transformation temperature by differential scanning calorimetry (DSC) and internal structure transmission electron microscopy (TEM) for sheets. Next, x-ray diffraction method two different textures. Then, measure distribution arising uniaxial tensile Finally, discuss 'mechanism angle, nucleation propagation band' 'relationship...

The fine structures of the lingual dorsal epithelium in musk shrew were observed by light and transmission electron microscopy. results showed that revealed three different cell lines microscopy, is, anterior posterior filiform papillae an interpapillar line. In line papillae, keratohyaline granules not observed. Instead, tonofibrils present cells deep intermediate layer hard keratinized shallow surface layers. found layer. Cells filled with numerous fibrous structures. Both soft apparent

The high-speed melt spinning of poly(ethylene 2,6-naphthalene dicarboxylate) (PEN) was performed up to the take-up velocity ultra-high-speed region, 9 km/min. From investigations structure and physical properties as-spun fibers, PEN divided into three regions in terms mechanism fiber formation. first region is 2.5 km/min birefringence 0.08 where only a slight increase molecular orientation attained. At 2.5–4.5 0.08–0.25, although some experimental evidences indicated that orientation-induced...

Heat sealing properties are optimized by controlling temperature, pressure and dwell time, while film strength depends on the drawn ratio molecular orientation of film. However, heat seal polymer films with high shows lower peel strength, because adhesion needs a higher energy for relaxation at sealing. In present study, polypropylene 1.0×, 1.5×, 2.5× sealed using technique. The condition is set to time 1.0 s, 0.2 MPa, temperature 145°C. effect stabilization PP investigated T-Peel test, DSC,...

Bread can be prepared using only rice flour if the viscoelastic properties of batter are appropriate. These depend on line due to differences in amylose content and architecture amylopectin between lines; consequently, rheology changed by made from various lines. In present study, we used three mutant lines, namely, Nipponbare, e1, #4019, which have different architectures contents. The baking qualities breads these lines were characterized expansion ratio bubble size. Cross-sectional images...

Heat generation caused by high-amplitude ultrasonic vibrations at the interface has long been believed to be most dominant factor for mechanism of plastic joining. However, authors have not found any conspicuous thermal effects in experiments joining thin very low density polyethylene (VLDPE) films using torsional vibrations. In process joining, temperature two VLDPE 0.1 mm thickness increased up 73 °C only and no trace melting material observed this under a polarizing microscope....
