This paper investigated the effects of combining fibers with self-consolidating concrete (SCC). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (PPS) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. All plans were subjected to fresh concrete tests. For mechanical behavior of...

The present study investigated whether intrinsic fatigability of the muscle fibers is reduced in patients with post-polio syndrome (PPS). This may contribute to the muscle fatigue complaints reported by patients with PPS. For this purpose, we assessed contractile properties and fatigue resistance of the knee extensor muscles using repeated isometric electrically evoked contractions in 38 patien...

in the current study an experimental/statistical approach addressing key mechanical properties (compressive, tensile and flexural strength) and impact resistance of such new fibers with inclusion of different volume of polyphenylene sulfide (pps) fibers has been carried out on 288 specimens. results from this study revealed that compressive, tensile and flexural strength exhibit a good fit with...

Immunohistochemical study of perivascular plaques (PPs) in 7 patients with Alzheimer's disease (AD) and 4 with cerebral amyloid angiopathy (CAA)(CAA with dementia in 3 patients and CAA with massive cerebral hemorrhage in 1 patient) demonstrated that PPs were also a common form of amyloid P (AP) deposits, like SPs and CAAs, in both AD and CAA, and that they had similar immunostaining characteris...

This work consists in investigating the influence of structural changes induced by annealing, such as presence a rigid amorphous fraction (RAF) and crosslinking, on mechanical properties polyphenylene sulfide (PPS) fracture behavior (particularly tenacity) Carbon/PPS laminated composite. The first part study aimed at obtaining PPS samples with different amounts RAF, determining conditions poten...

We examined the role of hippocampal galanin in an animal model of status epilepticus (SE). Control rats showed abundant galanin-immunoreactive (Gal-IR) fibers in the dentate hilus, whereas no Gal-IR neurons were observed. Three hours after the onset of self-sustaining SE (SSSE), induced either by intermittent stimulation of the perforant path for 30 min (PPS) or by injection of lithium and pilo...

The colon has a circular and longitudinal muscle layers and possesses an electric activity. The current study investigated the spread of this electric activity in the colonic musculature. The tests were performed in 16 patients (mean age 40.6 +/- 10.8 SD years, 10 men, 6 women) during operative correction of their incisional hernias in the anterior abdominal wall. Three electrodes were applied ...

In this research, the performance of ultrasonic pulse velocity (UPV) in concrete is examined as a nondestructive experiment in order to estimate mechanical (compressive and tensile strength) and durability (water absorption) properties of fiber-reinforced self-compacted concrete For this purpose 11 mixture designs containing 3 types of fibers (steel: 0.1, 0.2, 0.3 and 0.4 percent by volume, Pol...
