Corrosion Behavior of Welded Austenitic Stainless Steel in Different Environments
Abstract: Corrosion behavior of welded austenitic stainless steel in 0.5 M hydrochloric acid and wet-steam corrosive media has been studied. The immersion time in the corrosive media was 30 days to simulate the effect on stainless steel structures/equipment in offshore and food processing applications. Annealing heat treatment was carried out on the samples. The gravimetric technique was used for the corrosion tests. Seawater sample has highest weight loss of 4.0 mg …

Synthesis of Polyorthanisidine by Interfacial Polymerization
Abstract: AbstractPolyorthoanisidine has been synthesized by interfacial polymerization method. O-anisidine has been used as a monomer, hydrochloric acid is used as a dopant and ammonium persulphate as an oxidiser. The solvent used for the study is chloroform, isopropanol, hexane and xylene. The polyorthoanisidine obtained is characterized for particle size analysis. It is observed as with xylene as a solvent the least particle size has been observed with Z average value of …

Steel corrosion about application of inhibitors
Abstract: In chronology of prevention of irreversible degradation of metals, inhibitors to corrosion have studied to inhibit use of toxic inhibitors. Prevention of toxic inhibitors has further studied to explore non-toxic inhibitors prepared from biological origins, e.g. plant originated or underwater organisms or expired drugs. Toxic organic inhibitors are further studied to select those in which toxicity is removed by dilution of processing chemical. If water pipelines are considered use of …

Ru(III)-Catalyzed Oxidative Cleavage of Ritodrine Hydrochloride: A Kinetic and Mechanistic Study
Abstract: A systematic kinetic and mechanistic study of the oxidation of ritodrine hydrochloride (RTH) with chloramine-T (CAT) in both HClO4 and NaOH media has been carried out at 303 K. In acid medium, the reaction rate is very sluggish to be measured kinetically. Ruthenium (III) chloride ([Ru(III)]) was found to be an efficient catalyst. The reaction rate exhibits a first-order dependence on [CAT]0 in both media. It shows a fractional-order on …

Effective Homoeopathic Management of Allergic Rhinitis: A Case Series Utilizing Hepar Sulph 30 and Histamine 30 with Dietary Modifications
Abstract: Background: Allergic rhinitis (AR), means our immune system intruded by some allergens which is typically a harmless substance. These allergens are found in the air we breathe, in the food we eat, in the water and fluids we drink. These allergens are attacking on our immune system and the immune system responds to the allergens by releasing histamine and chemical mediators that cause symptoms in the nose, throat, eyes, ears, …

The Function of Diuretics in Current Medical Practice and Prospective Advancements
Abstract: Diuretics have a rich history that spans several centuries, and this review aims to highlight their progression and clinical uses. We start by exploring kidney physiology, followed by a description of how diuretics function through symporters in the renal tubules. Different categories of diuretics are outlined, along with details of their specific actions. Next, we investigate the clinical use of diuretics in conditions, such as congestive heart failure and hypertension, …

Innovative Antifungal strategies: Terbinafine hydrochloride in Niosomal carriers
Abstract: Onychomycosis, an infection caused by fungi that affects fingernails or toenails, causes the nails to grow, separate from the nail bed, and become discoloured. While anybody can get, those with weakened immune systems, children and the elderly are especially susceptible. Present study was related to formulate an effective nail lacquer that would treat onychomycosis by utilizing Terbinafine hydrochloride. In this study, niosomes of a medication called terbinafine hydrochloride, an antifungal …

Simple, Direct and Stability-Indicating UV Spectrophotometric Assay of Pioglitazone Hydrochloride in Pharmaceuticals
Abstract: Pioglitazone hydrochloride (PGH) is an antihyperglycemic agent used in the treatment of type-2 diabetes mellitus. A simple and straight forward UV-spectrophotometric method is presented for the determination of PGH in bulk drug and tablets by measuring the absorbance of drug solution in 0.1M H2SO4 at 269 nm. A plot of absorbance versus concentration obeyed Beer’s law over 2–36 µg ml-1 concentration range (r = 0.9981) with a molar absorptivity of …

Stability-Indicating Rp-Hplc Development and Validation for the Estimation of Lercanidipine Hydrochloride Content in Tablet Dosage Form
Abstract: A sensitive, stability-revealing, and easy reverse-phase high-performance liquid chromatographic (RP-HPLC) technique was developed and rationalized to be in a position to determine Lercanidipine hydrochloride in ingested dosing preparations. It was separated by chromatography on a C 18 column using a mobile phase containing 10 mM potassium dihydrogen phosphate buffer and methanol (20:80, v/v; pH 4.0) at a flow rate of 1.0 mL/min and UV detected at 258 nm. The retention …
