OBJECTIVES To determine whether autogenous tissue-engineered cartilage grafts can be synthesized in predetermined shapes, to compare tissue-engineered cartilage with native cartilage with respect to histological characteristics and biomechanical properties, and to demonstrate how multiple transplantations affect tissue-engineered cartilage. DESIGN Controlled, prospective animal study. SUBJE...

This paper attempts to find out the best available alternative material handling system (MHS), an integral component of warehouse operations. Analytic Hierarchy Process (AHP), a flexible decision making tool for complex, multi-criteria problems and useful to provide management weightage, has been used in this study to develop performance model. The proposed algorithm, used to select the proper ...

In order to optimize product designs it is necessary to quickly evaluate many candidate materials in terms of performance and processing costs. Evaluation using physical prototypes yields concrete results but is time intensive and costly when dealing with multiple optimization objectives. As an alternative, computer aided simulation is a reliable means of material evaluation and selection, is i...

For security, boards containing lead are commonly used to partition off rooms adjacent to radiation facilities. From the viewpoints of environmental safety and of material recycling during the process of remodeling or repair, however, the trend is toward avoiding the use of lead-containing radiation-protection board. Consequently, we developed a lead-free board(W 910xH 1820xD 12.5 mm)composed o...

Enamel demineralization is an undesirable but common complication of orthodontic fixed appliances therapy. The purpose of this study was to test long-term benefits of resin-modified glass ionomer cement (GC Fuji OrthoTM LC) for the prevention of demineralization in patients receiving orthodontic treatment with fixed bonded appliances. 90 healthy extracted premolars without any clinical signs of...

and spread during the summer to widely separated locations. In addition to white perch (Roccus americanus), striped bass (R. saxatilis) were involved to a lesser degree. Carefully selected moribund specimens were collected and delivered to the laboratory. Microscopy disclosed an abundance of polarly staining gram-negative rods in blood and organs of diseased fish. First isolations of these bact...

The article presents a hybrid monitoring technique for the measurement of the deformation field. The goal is to obtain information about crack propagation in existing structures, for the purpose of monitoring their state of health. The measurement technique is based on the capture and analysis of a digital image set. Special markers were used on the surface of the structures that can be removed...

Nano-TiO2 is widely applied in the automobile exhaust hose reels as a catalyst to reduce oxynitride emissions, including nitric oxide (NO). In the biomedicine field, NO plays an important role in vasodilation and edema formation in human bodies. However, the deswelling activity of nano-TiO2 has not been reported. Here, we demonstrated that nano-TiO2 can significantly degrade the production of N...

An alternative broiler litter to pine shavings may be switchgrass, a high yielding forage crop (8-12 tons per acre) that can grow across the Southeastern U.S. A study was conducted to determine the efficacy of chopped switchgrass as a litter material for broiler chickens. Pine Shavings (PS) and Switchgrass (SG) were used as litter treatments with 10 replications each. Body weight, body weight g...
