Spray application of polyurethane foam for thermal insulation of buildings represents the polyurethane application with the highest potential worker exposure to MDI. This paper reviews the existing work done to characterize the MDI exposures of the sprayed polyurethane foam workers as well as identifying several elements of an effective industrial hygiene program suggested by the existing work....

The foam generated by the mixture of air and water has a much higher viscosity and lower mobility than those of pure water or gas that constitutes the air-water foam. The possibility of using the air-water foam as a flow barrier for the purpose of groundwater and soil remediation is explored in this paper. A nanoparticle-stabilized air-water foam was fabricated by vigorously stirring the nano-f...

Three heat resistant cross-linked PVC foam plastics were prepared and their performances were compared with universal cross-linked PVC structural foam. The results show that these three heat resistant foams have higher glass transition temperatures (close to 100 °C) than universal structural foam (83.2 °C). Compared with the universal structural foam, the three heat resistant foams show much hi...

Objective: The present study was aimed to correlate the clinical tests with the laboratory measures under dual task conditions in Parkinson's disease (PD). Materials and Methods: Eleven people with idiopathic PD (Modified Hoehn and Yahr scores 1-3) were selected by simple non-probability sampling. Center of pressure (COP) data obtained by force platform was used to calculate mean total velocity...

In this article, the results of a study on energy absorption characteristics of foam-filled thin-walled structures with finite element analysis have been presented. Four specimens of thin walled structures have been filled with uniform foam and three specimens have been filled with linear four-layered foam. Also, eight layers HLH (High-Low-High) and eight layers LHL (Low-High-Low) have been sim...

BACKGROUND Pillows are intended to support the head and neck in a neutral position to minimize biomechanical stresses on cervical structures whilst sleeping. Biomechanical stresses are associated with waking cervical symptoms. This paper adds to the scant body of research investigating whether different pillow types produce different types and frequencies of waking symptoms in asymptomatic subj...

The present study was carried out to examine the changes in functional properties of cholesterol-removed compound whipping cream made by β-CD treated cream and palm oil. Six different ratios of cream to palm oil (10:0 as control, 9:1, 8:2, 7:3, 6:4, and 5:5, v/v) were tested. The overrun percentage increased with an increased amount of palm oil. When the ratio of cream to palm oil was 10:0 (con...

In staphylococci, quorum sensing regulates both biofilm formation and toxin production, moreover it has been demonstrated to be inhibited by RNAIII inhibiting peptide (RIP). Aim our study was to evaluate the in vitro activity and its in vivo efficacy of the combined administration of FS10, a novel RIP derivative, and tigecycline in an animal model of methicillin-resistant (MR) and methicillin-s...

Aluminum foam has received considerable attention in various fields and is expected to be used as an engineering material owing to its high energy absorption properties and light weight. To improve the mechanical properties of aluminum foam, combining it with dense tubes, such as aluminum foam-filled tubes, was considered necessary. In this study, an aluminum foam-filled steel tube, which consi...

BACKGROUND The introduction of sclerotherapy using foam sclerosants has revitalized interest in this method of treating varicose veins. Foam is made from detergent-type sclerosants already established as safe and effective in conventional liquid sclerotherapy. OBJECTIVE European experts in foam sclerotherapy were invited to exchange their opinions and to work on consensus statements and recom...
