aluminum foams are a novel branch of advanced materials with superior properties. sandwich structures with aluminum foam core are good energy absorbers. in this paper, mechanical properties and energy absorption of aluminum foam sandwich panels subjected to quasi-static perforation tests with conical-nosed indenter were investigated experimentally. for this purpose sandwich panels consisting of...

Milk protein concentrate (MPC) is one of the major ingredients in foods due to its nutritional and functional properties including solubility, water binding, foaming, and emulsification. The foaming ability of milk proteins could potentially allow them to replace egg white protein; however, there is a lack of research on foaming properties of MPC. The goal of this study was to investigate the e...

The remarkable stability of particle-stabilized foams and the opportunity to use them for production of novel porous materials have been attracting the researchers' attention in the recent years. The major aim of the current study is to clarify the factors, controlling the foamability and stability of foams, formed from concentrated silica suspensions in the presence of the amphoteric surfactan...

the brass tubes with foam cores of alsi7sic3, alsi7sic3fe1 and alsi7sic3fe3 were produced as the crush-boxes with circle and square cross-section. then axial compressive behavior and energy absorption capability of the foam-filled tubes were investigated during the quasi-static progressive plastic buckling. the uniaxial compressive stress–strain curves of the foam-filled brass tubes exhibited t...

ii Egg yolk contamination of egg whites continues to be a serious problem in the egg industry. The ability of egg whites to form stable and voluminous foams is greatly inhibited by accidental yolk contamination, even at extremely small levels. Experiments were conducted to determine if lipase can regenerate the functional properties of yolkcontaminated egg whites. Treatments included control, 0...

physical exercise would improve postural stability, which is an essential factor in preventing accidental fall among the elderly population. the aim of this study is to examine the effectiveness of treadmill walking on balance improvement among the elderly people. a total of 30 community dwelling older adults with a berg balance scale score of 36-48 and the ability to walk without aid were cons...

OBJECTIVE The scavenger receptors SR-A and CD36 have been implicated in macrophage foam cell formation during atherogenesis and in the regulation of inflammatory signaling pathways, including those leading to lesional macrophage apoptosis and plaque necrosis. To test the impact of deleting these receptors, we generated Apoe(-/-) mice lacking both SR-A and CD36 and fed them a Western diet for 12...

We describe a protocol for preparing very stable air-in-oil foams starting with a one-phase oil solution of a fatty acid (myristic acid) in high oleic sunflower oil at high temperature. Upon cooling below the solubility limit, a two-phase mixture consisting of fatty acid crystals (length around 50 mm) dispersed in an oil solution at its solubility is formed which, after whipping, coat air bubbl...

In the present study, we have studied advantages of using black rice husk ash nanoparticles as a foam stabilizer. It was shown that can potentially improve stability; therefore, allows one to reduce surfactant or polymer concentration needed control gas mobility in reservoir. previously published studies, authors reported results for this particular application. The study aims foam-forming abil...

AIMS Accumulation of foam cells in the intima is a hallmark of early-stage atherosclerotic lesions. Ginkgo biloba extract (EGb761) has been reported to exert anti-oxidative and anti-inflammatory properties in atherosclerosis, yet the significance and the molecular mechanisms of action of EGb761 in the formation of macrophage foam cells are not fully understood. METHODS AND RESULTS Treatment w...
