We demonstrate that catalytic micromotors can be trapped in microfluidic chips containing chevron and heart-shaped structures. Despite the challenge presented by the reduced size of the traps, microfluidic chips with different trapping geometries can be fabricated via replica moulding. We prove that these microfluidic chips can capture micromotors without the need for any external mechanism to ...

In this study, highly accurate measurements of density and dynamic viscosities a recombined live oil its mixture with additional CO 2 were performed. The experiments carried out under pressure temperature gradients found in Brazilian Pre-salt reservoirs, that is, the range from (27.6 to 68.9) MPa at (333.15 353.15) K. assumption volume change on mixing is evaluated experimental results, influen...

Quantitative description of how proteins fold under experimental conditions remains a challenging problem. Experiments often use urea and guanidinium chloride to study folding whereas the natural variable in simulations is temperature. To bridge the gap, we use the molecular transfer model that combines measured denaturant-dependent transfer free energies for the peptide group and amino acid re...

Introduction The complex organization of collageneous fiber network in joint cartilage and its load conditioned behaviour determines the biomechanical properties of this tissue. It has been shown that the state of health of the cartilage has an influence on the deformation mechanisms of the collagen network under compressive load [1, 2]. Thus, the compression tests could be a successful tool to...

Abstract A computational study was conducted to examine the seismic performance of steel moment‐resisting frames (MRFs) provided with chevron concentric braces. Such systems are widely used for buildings in Japan. Nonlinear finite‐element‐method models were validated against data and observations from previously tested chevron‐braced MRF specimens. The conduct a parametric understand how cyclic...

Seismic excitation can cause significant energy to be released within structures. By using special devices, this consumed and dissipated without deforming structural members significantly. Due this, damage is minimized, casualties are prevented during earthquakes, structures extended in their useful life. Over the past five decades, it has been widely acknowledged that steel yielding dampers am...

background: abnormal angulation of the lunate can be an indication of intercarpal pathology. on magnetic resonance images (mris) the lunate often looks dorsally angulated, even in healthy wrists. the tilt on individual slices can also be different and might be misinterpreted as pathological, contributing to inaccurate diagnoses and unnecessary surgery. the primary aim of this study was to deter...

conclusions although some of the orthopedic surgeons are not interested to manage these fractures surgically and most of them treat these cases conservatively (casting, etc.), in most displaced intra-articular calcaneal fractures, surgical treatment is the method of choice. moreover, in non-surgical treatment the prevalence of these complications among the patients is more and as a result, inev...
