“Resol resin composites reinforced with alkali-treated bamboo strips were fabricated

with a hand-lay-up technique. This study was aimed at the evaluation of the influence of the caustic concentration on the mechanical properties of bamboo-strip-rein forced resol composites with a constant 50% loading of the reinforcement. The treatment of bamboo fiber in a Solution of sodium hydroxide with increasing concentration percentages resulted in more and more rigid composites; as a result, the strength and modulus values GM6001 supplier exhibited improvements. The maximum improvement in the properties was possibly achieved with 20% caustic treated reinforcements. An infrared study indicated the formation of aryl alkyl ether with -OH groups of cellulose and methylol groups Of resol. Beyond 20%, there was degradation in all the strength properties due to the failure of the

mechanical properties of the reinforcement itself. A correlation was found to exist between the mechanical properties and the morphology that developed. Another set of composites with variable loadings of 20% alkali treated fiber (40, 50, and 60%) was fabricated, and a 60% fiber loading showed the best mechanical properties. 0 2009 Wiley Periodicals, Inc.

“We studied the reversal properties of perpendicular anisotropy (Co/Pd) multilayers with different crystallographic textures. In case of continuous films, an increase in the GS-7977 coercivity and reduction

in the switching field distribution (SFD) were observed as the growth is improved. From magnetic force microscopy, a stripe-type domain configuration was observed in films deposited at low gas pressure while a bubble-type domain was observed in high pressure deposited films. In patterned films, the SFD did not vary significantly for samples with different textures although a 2 kOe increase in the switching field was measured. In patterned structures, the controllability of SFD may not be related to the improvement of film crystallographic growth as was observed for unpatterned films. The results from this study indicate that local variation Apoptosis Compound Library nmr in the intrinsic film properties plays a major role in the SFD. (C) 2009 American Institute of Physics.

“Background The functional gastrointestinal disorders (FGIDs) are a heterogenous group of chronic conditions which cause troubling gastrointestinal symptoms. Though common and sometimes disabling, causing considerable social and economic burden, there is little recent literature on presentation or impact of FGIDs in Ireland.

Aim To describe the characteristics of patients with FGIDs at a tertiary referral clinic in Ireland.

Methods A retrospective review of those attending a university hospital gastroenterology clinic with a special interest in FGIDs between January 1999 and July 2008 was performed.
