Dynamic balance has frequently been evaluated by using center of pressure (COP) during stepping movement. COP sway may be greater during stepping on foam rubber, which is a kind of external load. This study aimed to examine the effect of leg-joint angles and COP sway during stepping on a spot in 13 young male adults (mean age 25.6 ± 4.8 years, mean height 170.6 ± 5.2 cm, mean mass 69.1 ± 8.2 kg...

The history of sclerotherapy of varicose veins of lower extremities dates back to 1840's. The use of stronger sclerosants thereafter led to serious complications, and the use of sclerotherapy decreased for varicose veins. However, sclerotherapy again became popular after introduction of safer sclerosant and compression sclerotherapy. After introduction of sclerosing foam in mid 1990's, many phl...

FOAM is ‘free open-access med(ical ed)ucation’. As such, FOAM is a dynamic collection of resources and tools for lifelong learning in medicine, as well as a community and an ethos. FOAM is continually evolving and growing rapidly, and from anarchic beginnings is increasingly attracting interest from practicing clinicians, trainees, educators, researchers and publishers alike. This article defin...

This work reports a novel thick-foam ferroelectret which is designed and engineered for energy harvesting applications. We fabricated this ferroelectret foam by mixing a chemical blowing agent with a polymer solution, then used heat treatment to activate the agent and create voids in the polymer foam. The dimensions of the foam, the density and size of voids can be well controlled in the fabric...

We present experimental results on the Stokes experiment performed in a 3D dry liquid foam. The system is used as a rheometric tool: from the force exerted on a 1 cm glass bead, plunged at controlled velocity in the foam in a quasi-static regime, local foam properties are probed around the sphere. With this original and simple technique, we show the possibility of measuring the foam shear modul...

BACKGROUND AND AIMS Mucosal healing is an important therapeutic goal for ulcerative colitis. Once-daily administration of budesonide 2-mg foam is widely used for inducing clinical remission. No study has assessed the usefulness of twice-daily budesonide 2mg foam on mucosal healing in ulcerative colitis patients. We explored the efficacy for mucosal healing of once- or twice-daily budesonide foa...

We have developed a new class of bistable Pickering foams, which can remain intact for weeks at room temperature but can be destroyed rapidly and on-demand with the use of a magnetic field. Such responsive foam systems can find application in various industrial and environmental processes that require controlled defoaming. These foams are stabilized by particles of hypromellose phthalate (HP-55...

Let G be the group of projectivities stabilizing a unital U in PG(2, q2). In this paper, we prove that U is a classical unital if and only if there are two points in U such that the stabilizer of these two points in G has order q2 − 1.

Liquid foams are used in areas such as mineral separation, oil recovery, food and beverage production, sanitation and fire fighting. To improve the quality of products and the efficiency of processes in these areas, foam scientists wish to understand and control foam behaviour. To this end, foam scientists have used foam simulations to model foam behaviour; however, analysing these simulations ...
