This study considered the practicality of groundnut shell ash (GSA) on laterite stabilized with lime for civil structures. Three site locations lateritic soil named specimen I, II and III were assembled from Ifewara, Atakunmosa West Local Government Area, Ilesa East Government, all situated in Osun State, Nigeria. Preliminary tests wrapped up specimens their characteristic states when optimum l...

background and aims. the aim of the present study was to compare the effect of surface treatment with er; cr:yssg, nd:yag, and co2 lasers on repair shear bond strength of a silorane-based composite resin. materials and methods. sixty eight cylindrical samples of a silorane-based composite resin (filtek silorane) were prepared and randomly divided into 4 groups as follows: group 1: without surfa...

bonding brackets to the enamel surface has gained much popularity today. new adhesive systems have been introduced and marketed and a considerable increase in research regarding bond strength has been published. a considerable amount of these studies deal with shear bond strength of adhesives designed for orthodontic purpose. previous studies have used variety of test designs. this diversity in...

objective: this study evaluated the effect of saliva contamination during bonding procedures without removing saliva on shear dentin bond strength of three adhesive generations when rubber dam isolation is not feasible. materials and methods: flat superficial dentin surfaces of seventy-two extracted human molars were randomly divided into three groups (a: scotch bond mp plus (sbmp), b: single b...

objective: considering the use of triple antibiotic paste (tap) for root canal treatment of open apex teeth, this study aimed to assess the effect of tap and calcium hydroxide (ch) on bond strength of composite to dentin.   methods: this in-vitro study was conducted on 32 extracted human premolar teeth. after disinfection with 2% thymol solution, the enamel on the buccal surface of specimens wa...

Unbound aggregates are the most common type of materials used for construction of the base layer of flexible pavements in Iran and worldwide. Due to the lack of binder, the performance of the compacted unbound aggregates is highly dependent on the properties of the gravel (particles remaining on sieve 4.75mm, sand (particles passing sieve 4.75mm and remaining on sieve 0....

ECCBR 2008 is the 9th European Conference on Case-Based Reasoning (CBR) following a series of successful European conferences and workshops. This four-day conference will be held at the University of Trier in Germany from 1–4 September 2008. The conference programme will include invited talks, oral and poster presentations as well as workshops (see separate calls) on both fundamental and applie...

Geosynthetics (GSN) are polymeric products used in Geotechnical Engineering for the purpose of improving properties insitu soil. In this project, experimental work was carried out to determine influence presence fines within granular soil on CBR strength reinforced with different GSN (Woven geotextile, Non-woven Geogrid and Geonet). Two types disturbed state containing varying percentage were s...
