BACKGROUND Traditionally, inlay casting waxes have been used to fabricate patterns for castings. Newer resin pattern materials offer greater rigidity and strength, allowing easier laboratory and intraoral adjustment without the fear of pattern damage. They also claim to possess a greater dimensional stability when compared to inlay wax. AIMS This study attempted to determine and compare the m...

Microfluidic paper-based analytical devices (μPADs) have emerged as viable multiplexable platforms with the potential to transcend existing analytical techniques in resource-limited settings. μPADs are fabricated by patterning hydrophobic materials on hydrophilic paper. Reproducibility in fabrication is essential in a myriad of applications and particularly, in the development of point-of-care ...

Chloride-induced corrosion has been one of the main causes reinforced concrete deterioration. One most used methods in assessing chloride penetration resistance is rapid migration test (RCMT). This an expeditious and simple method but may not be representative transport behaviour real environment. Other methods, like immersion (IT) wetting–drying tests (WDT), allow for a more accurate approach ...

BACKGROUND Dental esthetics, chewing and speech should be preserved in a dentition denominated functional and are closely related to satisfaction with oral health (SOH), impacts caused by oral problems and have a possible association with Oral Health-Related Quality of Life. Thus, the purpose of the present study was to investigate the influence of different concepts of functional dentition (FD...

Disorders of water balance are well recognized after traumatic brain injury (TBI), but there are no reliable data on their true prevalence in post-TBI patients. We aimed to evaluate the prevalence of posterior pituitary dysfunction in a large cohort of survivors of TBI. One hundred two consecutive patients (85 males) who suffered severe or moderate TBI were evaluated for diabetes insipidus (DI)...

Polyaniline and polyamide (nylon 6,6) nanocomposites with Silva were prepared by in-situ oxidativepolymerization of aniline monomers in the presence of Ag salt Nano particles of silver (NPs) were symthesieedby controlled reduction of Ag+ ions kith sodium borohydride at room temperature. Nylon 6,6 wax loaded withAg nanoparfieles by erdrapment of Ag+ ions into the polymer network, followed by red...

Crude oil plays an important role in providing the energy supply of the world, and pipelines have long been recognized as the safest and most efficient means of transporting oil and its products. However, the transportation process also faces the challenges of asphaltene-paraffin structural interactions, pipeline pressure losses and energy consumption. In order to determine the role of drag-red...

As the investigation indexes of low-temperature viscoelastic properties polymer-modified asphalt (PMA) are unclear at present, in this paper, creep stiffness (S), rate (m), continuous classification temperature (TC), ΔTC, m/S, relaxation time (λ), and dissipation energy ratio (Wdt/Wst) were taken as a comparison sequence. The maximum flexural tensile strain (εB) porous mixture (PAM) bending tes...
