Recently we need to manage statistical process controls to maintain product quality based on the sensor technology such as small thermometers and displacement sensors, which can give as vast information on production parameters. In bag-making process, the strength of bags is very difficult to estimate without any distraction of products, and it sometimes needs a large sample size. In place of t...

There is strong evidence that pinnipeds maintain a lipid-based, aerobic metabolism during diving. However, the few fiber-typing studies performed on pinniped skeletal muscles are not consistent with an aerobic physiological profile. The objective of this study was to reexamine the fiber type distribution throughout the primary locomotory muscles of the harbor seal Phoca vitulina. Results from i...

objectives: this study aimed to evaluate the effect of chlorhexidine (chx) application protocol on durability of marginal seal of class v composite restorations. materials and methods: class v cavities (4×2×1.5mm) were prepared in the buccal surfaces of 160 human third molars. the teeth were randomly divided into five groups (n=32) of (g1) chx+rinse+etching, (g2) chx+etching, (g3) etching+chx+r...

the sealness of wilayah is one of the most important and challenging issues discussed by muslim mystics, and has been discussed by the likes of ibn ‘arabi. like other mystics, ibn ‘arabi divides wilayah into two types: absolute and limited. however, his ideas with regards to instances of absolute wilayah and limited wilayah diverge from the norm. sometimes this divergence is so extreme that acc...

The primary objectives of this study were to validate a canine relaxin RIA for use in otariids and phocids and consider practical applications. For 6 captive Northern fur seal females, serum samples were grouped and examined according to pregnancy (n=13), post-partum (n=8) and non-pregnancy (n=6), and, for 2 captive Northern fur seal males, serum samples were grouped and examined together regar...

Patch clamping depends on a tight seal between the cell membrane and the glass of the pipet. Why does the seal have such high electric resistance? Why does the patch adhere so strongly to the glass? Even under the action of strong hydrostatic, adhesion, and electrical forces, it creeps at a very low velocity. To explore possible explanations, we examined two physical models for the structure of...

OBJECTIVE To compare a seal-in liner with the common suction socket with regards to patient satisfaction and problems experienced with the prosthesis. DESIGN Retrospective survey. SETTING A medical and engineering research center and a department of biomechanical engineering. PARTICIPANTS Men (N=90) with traumatic transfemoral amputation who used both suspension systems participated in th...

When a marine stern shaft is bent with shafting misalignment and stern bearing wear factors, etc., the sealing properties of a plane mechanical seal is declined with the increase of both contact pressure and temperature of sealing surface, so a spherical mechanical seal which can automatically adjust the contact state of sealing surfaces is proposed to replace the plane mechanical seal in order...

We present new and revised data for the phocine distemper virus (PDV) epidemics that resulted in the deaths of more than 23 000 harbour seals Phoca vitulina in 1988 and 30,000 in 2002. On both occasions the epidemics started at the Danish island of Anholt in central Kattegat, and subsequently spread to adjacent colonies in a stepwise fashion. However, this pattern was not maintained throughout ...

Seals with beaded whiskers-the majority of true seals (Phocids)-are able to trace even minute disturbance caused by prey fish in the ambient flow using only sensory input from their whiskers. The unique three-dimensional undulating morphology of seal whiskers has been associated with their capability of suppressing vortex-induced vibration and reducing drag. The exceptional hydrodynamic traits ...
