Semi-buried structures are most commonly used at first line of defense along the border between two countries. This demands investigation of their dynamic behaviour under blast loading. Herein, a semi-buried structure with foam sandwiched walls and buttresses to reduce the effect of blast is analysed. The effect of provision of different configurations of buttresses and foam core between two la...

Milk-based espresso coffee is one of the most popular beverages. Foam is an essential quality characteristic for this beverage. Foam formation and stability is mainly related to the milk composition. In this study the influence of three different concentrations of Xanthan gum (0.05, 0.1 and 0.2 g dm-3) and three different temperatures (50, 60 and 70 °C) on foam stability were examined and exper...

Foam-enhanced oil recovery (EOR) is poised to become one of the most promising tertiary techniques keep up with continuously increasing global energy demands. Due their low sensitivity gravity and permeability heterogeneities that improve sweep efficiency, foams are preferred injection fluids over water or gas. Although foam has been used in field control gas mobility, its success still hindere...

BACKGROUND Foam sclerotherapy is an increasingly popular modality in varicose vein treatment. Our previous work showed that the half-life of room air foam varied according to the percentage and type of sclerosant solution. MATERIALS AND METHODS A plastic connector was used to create foam made from a combination of 0.25%, 0.50%, and 1% sodium tetradecyl sulfate (STS) and room air, carbon dioxi...

Nitrogen-doped flexible carbon foam was used to fabricate a lithium sulfur battery. The stability and rate performance of the battery were evaluated. The battery with carbon foam calcined at 800 °C displayed superior stability compared with other tested batteries. Battery performance was closely related to the foam structure and component. However, good rate performance was achieved with the fo...

A study was conducted to determine the effect of foam extract on sperm motility in the male Japanese quail (Coturnix coturnix japonica). Adult male quails (<12 weeks) of heavy body weight strain were housed in individual cages and divided into 5 groups according to the size of their cloacal glands. The data indicated that the size of the cloacal gland was positively correlated with the frequenc...

A model aqueous film-forming foam (AFFF) comprising a fluorocarbon surfactant (6:2 FTSaB), hydrocarbon surfactant, solvent, and water was deployed on heptane fire with the gravimetrically-drained solution collected at regular time intervals analysed for concentration. Foam drainage behaviour within system non-linear both control (no exposure) fire-exposed tests, as would be expected. However, c...

Abstract Gas, which is trapped in either solid or liquid pockets, results foam formation. Foam formation common many industries, i.e., detergents, food and beverage, cosmetics, fire-fighting. excess causes biotechnology fermentation instabilities, including material loss the danger of contaminating environment. Many foam-controlling measures have been reported, thermal, enzymatic, mechanical, u...

Wet granulation using foaming binder solution is a new approach of liquid delivery to create granules. This study compares wet granulation via foamed binder addition method and sprayed binder addition method by studying the kinetics of foam and drop penetrations into loosely packed powder beds. Foam and drop nucleation kinetics were compared by examining specific penetration time (penetration t...
