PCI JOURNAL This paper presents the results of nonlinear fi nite element analyses conducted to model the behavior of L-shaped, precast, prestressed concrete spandrels constructed with open web reinforcement. The fi nite element model was calibrated using experimental results from recent tests of slender, L-shaped, precast, prestressed concrete spandrels. Detailed correlative studies between ana...

The more than 4,000 living species of mammal have infiltrated almost every habitat in the world. From alpine mountaintops to plains grasslands, from aerial heights to the depths of the ocean, from slender forest branches to narrow subterranean burrows, mammals occupy an extraordinary variety of substrates. Some are capable of running, swimming, or swinging at great speeds, while others creep sl...

We report on a girl with a partial duplication of the proximal part of the long arm of chromosome 10, confirmed by chromosome painting. The phenotypic findings are compared to those found in six other published cases with the same karyotype. Recognition of a specific partial proximal trisomy 10q syndrome seems to be possible, consisting of mild to moderate developmental delay, postnatal growth ...

This study explores the elastohydrodynamic lubrication (EHL) between contacting tooth flanks of a worm gear with nonconjugate meshing action. The contact is characterized by slender-like elliptical shape and high sliding. geometry conditions for considered were obtained using analysis. Based on that, complete area was analyzed validated numerical EHL model considering non-Newtonian, thermal, tr...

Excessive deformations and chatter vibrations are two main obstacles frequently encountered in turning of long slender workpieces. So far, there is seldom reported research using optimization techniques to cope with those difficulties. This paper introduces a new method for optimizing the machining parameters and the sequence of cutting passes in turning of a slender rod to control the deformat...

This paper deals with the study of the behaviour of a slender beam introduced in a cylindrical tube and subjected to an axial compressive force. The beam is very long compared to its transversal dimensions and therefore it will buckle to a very small axial force. The post-buckling behaviour is examined. The study has important applications in the petroleum industry, for coiled tubing in the cas...

African sleeping sickness is a disease caused by Trypanosoma brucei. T. brucei proliferate rapidly in the mammalian bloodstream as long, slender forms, but at higher population densities they transform into nondividing, short, stumpy forms. This is thought to be a mechanism adopted by T. brucei to establish a stable host-parasite relationship and to allow a transition into the insect stage of i...

Jacketing of reinforced concrete columns is a common and useful strengthening method. This method substantially improves mechanical properties of the column, such as flexural strength as well as shear and ductility. In this paper, the behavior of confined reinforced concrete columns are investigated. The results indicate that the method is more effective for slender columns in the region of the...

We report two cases of successful percutaneous coronary intervention (PCI) using a 4-in-3 "Slender Mother and Child" PCI technique. In both cases, coronary angiography revealed severe stenosis of the right coronary artery (RCA). In both cases, 5-Fr sheathless guiding catheters were inserted into the RCA (virtual 3-Fr PCI) but stents could not pass through because of stents previously implanted ...

Due to the lack of continuous flows that would wash unwanted specifies and impurities off from a target location, droplet microfluidics commonly employs a long serial dilution process to purify target species. In this work, we achieve high-purity separation for the case of electrowetting-on-dielectric (EWOD) based droplet microfluidics by introducing a "fluidic conduit" between a sample droplet...
