failure in timber structures occurs mainly in crucial points such as joints areas. therefore, the idea of using composite sheets in timber joints has been intro-duced as a method in order to increase the strength and ductility behaviour of timber joints. this research aims to study the behaviour of bolted joints in poplar and pine woods, which are reinforced by two types of gfrp sheets. a singl...

PURPOSE Preferences of both Alzheimer patients and their spouse caregivers are related to a willingness-to-pay (WTP) measure which is used to test for the presence of mutual (rather than conventional unilateral) altruism. METHODOLOGY Contingent valuation experiments were conducted in 2000-2002, involving 126 Alzheimer patients and their caregiving spouses living in the Zurich metropolitan are...

We describe a 16 year old patient who developed Still's disease with evidence of myocarditis. A rise in the mumps 'V' antigen indicated that the disease was associated with recent mumps infection.

The Maximum Density Sill-Life Problem is to fill an n × n board of cells with the maximum number of live cells so that the board is stable under the rules of Conway’s Game of Life. We reformulate the problem into one of minimising “wastage” rather than maximising the number of live cells. This reformulation allows us to compute strong upper bounds on the number of live cells. By combining this ...

BACKGROUND Primary jejunal gastrinomas are exceedingly rare, and data for long-term follow-up is limited. Until now, only six cases of gastrinomas arising from the jejunum have been reported in the English literature. CASE PRESENTATION Presented is a case of a primary gastrinoma located in the proximal jejunum. After surgical resection of the tumor, eugastrinemia was quickly achieved and afte...

Most of the laboratory tests investigated the flexural performance of un-preloaded or undamaged RC beams strengthened with CFRP composites. However, in engineering applications, the structural member must carry a certain load or damage. There is a lack of systematical investigations on the effects of preload or damage level on the flexural load-carrying capacity of CFRP-strengthened RC beams. T...

The use of near-surface mounted (NSM) fibre-reinforced polymer (FRP) bars is an interesting method for increasing the shear and flexural strength of existing timber members. This article examines the behaviour of carbon FRP (CFRP) bars in timber under direct pull-out conditions. The objective of this experimental program is to investigate the bond strength between composite bars and timber: bar...

in order to investigate the flexural behaviors of rc beams after freeze-thaw cycles, compressive strength test of concrete cubes after 0, 50, 100, 125 freeze-thaw cycles were made, and static flexural experiment of 48 rc beams after 0, 50, 100, 125 freeze-thaw cycles were made. the relationships of relative compressive strength, mass loss rate, relative dynamic elastic modulus and numbers of fr...

To the editor: The recent report by Muscat et al., on the 2009 to 2011 measles outbreak in Bulgaria, emphasised that this infectious disease still represents a health issue of concern that can re-emerge with a substantial magnitude in Europe [1]. Indeed, this epidemiological analysis recorded 24,364 cases in Bulgaria between April 2009 and December 2011 and, importantly, around 73% of those inf...

The relationship between diet and the development of chronic disease still remains a controversial area. One major difficulty is to obtain a valid estimate of habitual pattern and level of food consumption for each individual. There is, in fact, a voluminous and largely negative literature on the validity of dietary assessment methods. In the present paper the utility of the most frequently use...
