An assessment of the material properties of three types of touch and close fasteners (Velcro) in general orthopaedic usage is presented. The materials were tested under various loading regimes using an Instron testing machine. The force-extension curves were analyzed and values determined for both the stiffness and strength of the various attachments. Particular reference was made to the altera...

Friction measurement is one of important and interesting problems in the study of handle properties of fabrics. Different methods have been developed for measuring friction, such as sliding, KES and cyclic testing method. In this research, considering the possibilities of varying conditions in measuring friction, a new instrument by which the bottom surface of fabric can be moved and the top sl...

Nowadays acoustic emission (AE) testing based on the Kaiser Effect (KE) is increasingly used to estimate the in-situ stress in laboratories. In this work, this effect is assessed on cylindrical specimens in numerical simulations of the cyclic loadings including loading, unloading, and re-loading cycles using a 3D code called the particle flow code (PFC) based upon the distinct element method. T...

Cyclic compression fatigue properties of concrete are studied with the ultrasonic testing method cycling frequency 19 kHz and compared to servo-hydraulic tests performed at 60 Hz. Ultrasonic was found applicable for rapid generation very high cycle (VHCF) data concrete. Fatigue cracks can be initiated, however specimens do not rupture, since cyclic stresses decrease increase compliance in displ...

mixed clayey soils occur as mixtures of sand (or gravel) and clay in widely varying proportions. their engineering behavior has not been comprehensively studied yet. an experimental program, comprising monotonic, cyclic, and post-cyclic triaxial tests was undertaken on compacted clay-granular material mixtures, having different proportions of clay and sand or gravel. this paper presents the res...

Earthquake performance of wood-frame shear walls was evaluated by comparing fully and partially anchored walls under monotonic, cyclic, and earthquake loads and comparing with code measures. Suitability of monotonic and cyclic testing to predict seismic performance was examined. Earthquake tests were conducted on 2440-mm-square walls with Douglas-fir studs. Two oriented strandboard panels were ...

Protein-protein and protein-peptide interactions are responsible for the vast majority of biological functions in vivo, but targeting these interactions with small molecules has historically been difficult. What is required are efficient combined computational and experimental screening methods to choose among a number of potential protein interfaces worthy of targeting lead macrocyclic compoun...

The aim of this randomised, controlled in vivo study in an ovine model was to investigate the effect of cyclic pneumatic pressure on fracture healing. We performed a transverse osteotomy of the right radius in 37 sheep. They were randomised to a control group or a treatment group where they received cyclic loading of the osteotomy by the application of a pressure cuff around the muscles of the ...

Almwct--Two new computationally efficient afgorithms are developed for fmdiug tke exact burst-comxtiug limit of a cyclic code. The first algorithm is based on testing tbe culumn rank of certain submatrices of the parity& matrix of the code. Aa auxiliary result is a proof that every cyclic (n,k) code, with a min immu distauce of at least three, CorrecQ at least all bursts of length L(n-2k+l)/2J ...

Recent advances in computational methods allow the Characteristic and Acyclic Polynomials of a Chemical Graph to be calculated easily. A consequence of this is that checking for a zero-value remainder after computer assisted polynomial division is sometimes the simplest way of testing suspected factors of a chemical graph. The technique is simple enough to apply on a routine basis when characte...
