Commercial bamboo chips were evaluated as raw material for dissolving pulp production. The chips were auto-hydrolyzed (AH) and subsequently cooked by the NaOH/AQ process and bleached to full brightness with the O-CCE-D-(EP)-D-P sequence. The term CCE designates a cold caustic extraction stage. The bamboo chip chemistry (22.4% lignin, 19.5% xylans, 49.3% cellulose, 16.8% total extractives, and 1...

OBJECTIVES The aim was to evaluate the shelf life and the dissolving and antibacterial properties of a neutralized 2.5% NaOCl solution. STUDY DESIGN The loss of available chlorine and the pH of the neutralized 2.5% NaOCl solution were recorded to determine its shelf life. The dissolving action on bovine dental pulp was assessed measuring weight loss, pH variation, and decrease in available ch...

conclusions based on our findings, we conclude that the separation and reproduction of adipose tissue cells is an appropriate method for purification of mscs in animal studies. regarding the histomorphometric and flow cytometry analysis results, we demonstrated the differentiation ability of mscs in normal medium and hope to employ these cells for the regeneration of damaged bone tissues in the...

I study a market where agents with unit demand jointly own heterogeneous goods. In this market, the existence of an efficient, incentive compatible, individually rational, and budget balanced mechanism depends on the shares of the agents. I characterize the set of shares for which having such a mechanism is possible. This set includes the symmetric allocation and excludes the allocation in whic...

In this paper we present our approach to dissolving the learning boundaries that make it hard for IT students to adopt learn about user-focussed design and development. Traditional approaches to IT teaching minimise collaboration and reuse, favouring inflexible, sequential, heavyweight development methods that view user value as having secondary importance at best. In contrast, we use a studio-...

In financial disputes arising from divorce, inheritance, or the dissolution of a partnership, frequently the need arises to assign ownership of an indivisible item to one member of a group. This paper introduces and analyzes a dynamic auction for simply and e¢ciently allocating an item when participants are privately informed of their values. In the auction, the price rises continuously. A bidd...
