In cooking, food gels, such as agar-agar or alginate, are often prepared and presented in the form of spheres spaghetti. While experimenting our kitchen, we realized that it is quite difficult to make more advanced shapes. this study, sought develop new methods obtain complex Our first challenge was helices. The best method selected deposit solutions before their gelation a thread. robustness t...

We propose a vena cava filter in which helical flow is created in the filter's working zone to minimize filter blockage by trapped clots and facilitate the lysis of trapped clots. To validate this new design, we compared five helical flow inducers with different thread pitches in terms of blood flow patterns in the filter. The vena cava was reconstructed based on computed tomography images. Bot...

The aim of this study was to evaluate the effect of pitch distance on the primary stability (PS) of orthodontic mini-implants (MIs) in artificial bone. Twenty experimental MIs were allocated to two groups, according to their geometric design: G1 (30o X 0.6 mm) and G2 (45o X 0.8 mm), and inserted into artificial bone of different densities: D1 (0.32 g/cm3) and D2 (0.64 g/cm3). The maximum insert...

The purpose of this study was to determine the influence of gender, screw design, and the approach on maximal screw length in scaphoid fracture fixation. Measurements were performed on 3D reconstructions of 20 CT scans of normal scaphoids. A comparison was made between 15 different available screw designs and between volar and dorsal screw placement. The length of the scaphoid along its central...

We present the design and implementation of Arachne, a threads system that can be interfaced with a communications library for multi-threaded distributed computations. In particular, Arachne supports thread migration between heterogeneous platforms, with dynamic stack size management and recursive thread functions. Arachne is eecient, exible and portable | it is based entirely on C and C++. To ...
