A two-dimensional heat transfer model for transient simulation and control of a continuous steel slab caster is described. Slab thermal and solidification conditions are computed by the model as a function of time-varying casting speed, secondary spray cooling water flow rates and temperature, slab thickness, steel chemistry, and pouring and ambient temperatures. A solidification model that inc...
Fuel-flexible aircraft propulsion systems using compression ignition engines will require novel strategies for reducing the delay of low-reactivity fuels to feasible timescales. Hot surface fuel sprays has been implemented in some practical situations, but complex nature flame formation within spray structure poses significant challenges. In order design next-generation devices, capacity hot he...
In order to improve local therapeutic techniques for the massively burnt patients and to minimize the pain associated with dressing change, the concept of topical film was utilized to formulate a topical antimicrobial spray. The commonly used topical antimicrobial silver sulfadiazine spray was formulated as a new drug delivery system. The release of therapeutic agents in vitro from medicated sp...
One of the solutions to reduce pollutants and increase engine power is to use water spray in internal combustion engines. In this type of engine, fuel and water sprays play an important role in engine performance. In this regard, the purpose of this study is to accurately simulate fuel and water sprays and provide optimal coefficients to achieve the best simulation results. For this purpose, th...
OBJECTIVE Fear of pain during intrauterine device (IUD) insertion can be a barrier to widespread use of this safe and highly effective contraceptive method. Our objective was to determine the effectiveness of topical 10% lidocaine spray for pain control during IUD insertion. METHODS A total of 200 subjects with the request for IUD insertion were included in the study. The patients were random...
Heat transfer rate at the skin-air interface is of critical importance for the benefits of cryogen spray cooling in combination with laser therapy of shallow subsurface skin lesions, such as port -wine stain birthmarks. With some cryogen spray devices, a layer of liquid cryogen builds up on the skin surface during the spurt, which may impair heat transfer across the skin surface due to relative...
Spray drying is a promising method for the stabilization of vaccines, which are usually formulated as liquids. Usually, vaccine stability is improved by spray drying in the presence of a range of excipients. Unlike freeze drying, there is no freezing step involved, thus the damage related to this step is avoided. The edge of spray drying resides in its ability for particles to be engineered to ...
The effect of various humidities on process yields and degrees of crystallinity for spray-dried powders from spray drying of lactose with humid air in a straight-through system have been studied. It has been suggested by Williams–Landel–Ferry kinetics (WLF) that a higher particle temperature and lower glass-transition temperature would increase the crystallization rate of the particles during t...
OBJECTIVE A new nicotine mouth spray was shown to be an effective stop-smoking treatment. This study was set up to examine the speed with which it relieves urges to smoke, and how it compares with nicotine lozenge in this respect. DESIGN Randomised, cross-over trial that compared nicotine mouth spray 2 mg versus nicotine lozenge 2 or 4 mg. SETTING Clinical pharmacology research unit. PART...
The aim of this article was to study the trans-epithelial absorption to reach the blood and to target the brain by axonal transport using nasal formulations with nanonized meloxicam (nano MEL spray) and its salt form known as meloxicam potassium monohydrate (MELP spray). The physicochemical properties and the mucoadhesivity of nasal formulations were controlled. In vitro and in vivo studies wer...
