A 7-year-old male was brought to our emergency department with a sensation of a persistent lump in his throat after drinking an unsealed carbonated beverage. Flexible nasopharyngoscopy revealed a black ant in the right hypopharynx. Despite repeatedly drinking water, the ant could not be swallowed, and it had firmly attached to the posterior pharyngeal wall (Figure 1). After discussion with his ...

Transcranial direct current stimulation (tDCS) is a neuromodulation scheme where a small current is delivered to the brain via two electrodes attached to the scalp. The electrode design is an important topic, not only as regards efficacy, but also from a safety perspective, as tDCS may be related to skin lesions that are sometimes observed after stimulation. Previous computational models of tDC...

The filter cake layer, which is essential to reduce the fluid invasion drilled formation, has been reported be composed mainly of weighting materials. complete removal this layer recommended restore rock permeability. Hematite one material that used create cake. However, cleanup hematite-based not studied thoroughly. objective work presented in paper investigate hematite water-based using hydro...

Abstract Injection of imbibition fluids or CO2 during hydraulic fracturing is an effective stimulation method for tight oil reservoirs. Selecting appropriate agents significant to optimize the integrated scheme and production in In this study, a series lab experiments, including spontaneous imbibition, dynamic huff puff, were carried out using real cores, water absorption apparatus, core floodi...

Distillers dried grains with solubles (DDGS) is the main co-product from grain-based ethanol production. The objective of this research was to compare the adhesive performance of three types of sorghum proteins: acetic acid-extracted sorghum protein from DDGS (PI), aqueous ethanol-extracted sorghum protein from DDGS (PII) and acetic acid-extracted sorghum protein from sorghum flour (PF). Physic...

Bioretention, also known as rain garden, allows stormwater to soak into the ground through a soil-based medium, leading to removal of particulate and dissolved pollutants and reduced peak flows. Although soil organic matter (SOM) is efficient at sorbing many pollutants, amending the bioretention medium with highly effective adsorbents has been proposed to optimize pollutant removal and extend b...

The present investigation attempted to assess the impact of seed pre-treatments on the germination of Crotalaria persica (Burm. f.) Merr and Tephrosia apollinea (L) Pers. Equally important was our investigation to quantitatively compare different germination parameters used for seed germination studies. The results showed that the final germination was highest for both species under chipping (C...

The coefficient of thermal expansion of core and veneer porcelains for all ceramic crowns must be compatible to prevent formation of stresses during the firing cycles. The purpose of this study was to use a thermal shock test to evaluate the crazing resistance of six all-ceramic crown systems. The systems tested were: Vita In-Ceram, Vita Hi-Ceram, Dicor veneered with Vitadur N, magnesia core ve...

Introduction: Infectious mouth diseases are caused by microorganisms such as Staphylococcus aureus and Streptococcus mutans. Sentul fruit peel extract contains several phytochemical compounds, flavonoid saponins tannins aromatic hydroxyl groups that act antibacterial so they can be used a treatment for infections of the mouth. This study aimed to determine inhibitory ability (Sandoricum koetjap...
