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...

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...
