Keratitis is an inflammation of the cornea (the clear, front part of the eye) and is often caused by bacteria, viruses, amoeba, fungi. There are two types of keratitis infectious ulcerative keratitis (IUK), caused by infectious pathogens and noninfectious ulcerative keratitis (NIUK), which has a clinical presentation similar to that of IUK but no known infectious cause and is a diverse disease ...

Geopolymer concrete mixes were cast using fly ash, kaolin, sodium hydroxide, potassium hydroxide, sodium silicate and aggregates. Portland cement concrete (M30) was used as a reference sample. The effect of silica fume, temperature (40 °C, 60 °C, 80 °C, 100 °C and 120 °C), sodium and potassium hydroxides and different superplasticizers on the compressive strength are reported [1]. Maximum stren...

IMPORTANCE Onychomycosis is the most common disease of the nail in adults. International guidelines urge health care professionals to perform confirmatory diagnostic testing before initiating systemic therapy. This approach was determined to be cost-effective in studies from the late 1990s but has not been evaluated more recently. The effect of testing on the costs of efinaconazole, 10%, topica...

BACKGROUND Plane wart is a common dermatological disease that is caused by human papilloma virus; although the rate of spontaneous recovery is high, it usually takes a long time to occur. Many modalities of treatments have been used but none of them proved to be uniformly effective. Potassium hydroxide (KOH) solution is a well-known keratolytic agent with many dermatological uses. OBJECTIVE T...

In this work, chemically treated microcrystalline cellulose (MCC-C) was extracted from coconut husk fiber. order to extract hemicellulose, the sieved fiber with sodium hydroxide (NaOH) for dewaxing and acidified using chlorite (NaClO2) residual lignin (bleaching process). The obtained lignin-free then potassium (KOH). characterizations used equate MCC-C commercial grade (MCC) are solubility tes...

Abstract The use of geopolymers as a full replacement for cement in oil well cementing applications requires the development not only environmentally friendly but also user-friendly cementitious materials. This study aims to investigate early-age mechanical and chemical properties synthesized one-part geopolymers, which are heat-cured rock-based products. These were from granite-based precursor...

The present work deals with the preparation and characterization of activated carbons from bark asparagus palm (Laccosperma robustum) by chemical activation phosphoric acid potassium hydroxide. process was optimized on basis analysis iodine number, methylene blue number yield as a function parameters (concentration activating agents pyrolysis temperature). It emerges that temperature concentrat...

One-part or “just add water” alkali activated materials (AAMs) have attracted a lot of attention thanks to the use solid alkaline activators that makes these more suitable commercialization compared conventional AAMs (two-part). This is mainly because large quantities caustic solutions should be handled for producing AAMs. So, one-part great potential in-situ applications. However, heat curing ...

There is a desperate demand for efficient energy storage systems to fulfill future demands. Herein, we exemplify facile solvothermal approach followed by heat treatment synthesize NiO/g-C3N4 nanocomposites enhanced supercapacitor applications. The molar ratio of g-C3N4 varied achieve numerous nanostructures like nanoparticles and nanorods with optimum specific capacitance. Further, all as-prepa...
