Abstract The relationships between friction coefficients and 3D spatial roughness parameters, such as Sci (surface core fluid retention index), Svi valley index) Sbi bearing have been investigated for the laser-induced periodic surface structures (LIPSS) on TiN coatings. Two types of (cross-like parallel ones) with different levels were obtained using a fs-laser. It has shown that proposed para...

In this investigation the denture retention was measured and the influence of denture -retention on ima'sticatory efficiency was examined. The investigation was iperf armed on 36 comiplete denture wearers. The test of masticatory efficiency wals used according to Ni'kšić (1965). The meaisuriinig of denture retention was made by specially constructed mechanical scale, which wa's designed so that...

A quantitative structure-property relationship (QSPR) study based on multiple linear regression (MLR) and artificial neural network (ANN) techniques is carried out to investigate the retention time behavior of some pesticides on the DB-5ms fused-silica column in gas chromatography. Five descriptors selected in the MLR model are: first component WHIM index (E1v), highest eigenvalue n.7 of burden...

The expression of intron-containing messages has been shown to occur in a variety of diseases including lactic acidosis, Cowden Syndrome, and several cancers. However, it is unknown whether these intron-containing messages result in protein production in vivo. Indeed, intron-containing RNAs are typically retained in the nucleus, targeted for degradation, or are repressed translationally. Here, ...

Microcystic meningiomas are rare but benign brain tumors. Previous reports have shown that Thallium-201 single-photon emission computed tomography ((201)Tl SPECT) demonstrated a higher late-phase accumulation of (201)Tl in malignant or recurrent meningiomas than in nonaggressive meningiomas. No study has reported (201)Tl SPECT findings in microcystic meningiomas. We here describe a case of a mi...

BACKGROUND We tested the hypothesis that ventilatory drive in hypoxia and hypercapnia is inversely correlated with the number of hypopneas and obstructive apneas per hour of sleep (obstructive apnea hypopnea index, OAHI) in children. METHODS Fifty children, 6 to 12 years of age were studied. Participants had an in-home unattended polysomnogram to compute the OAHI. We subsequently estimated ve...

The main purpose of this study is to evaluate the effect of staffs' customer orientation on customer satisfaction, commitment and retention. For this aim, the model of customer orientation of service staff, offered by Thurau was combined with customer orientation model of Donavan and Hoctt and a new model was devised for Mellat Banks of North West of Iran. The trend of this research is applied,...

BACKGROUND Transverse nasal crease is an uncommonly reported entity. It likely represents an embryologic fault line. Transverse nasal milia have also been reported in the same location, both as an isolated finding and in a transverse nasal crease. This observation suggests they are variants of the same entity. OBSERVATIONS Two cases, one of transverse nasal crease with milia and one of transv...
