Abstract In this paper, multi-objective optimization (MOO) of Al2O3-water nanofluid flow in microchannel heat sinks (MCHS) with triangular ribs is performed using Computational Fluid Dynamics (CFD) techniques and Non-dominated Sorting Genetic Algorithms (NSGA II). At first, nanofluid flow is solved numerically in various MCHS with triangular ribs using CFD techniques. Finally, the CFD data will...

The diaphragm acting alone causes a cranial displacement of the lower ribs and a caudal displacement of the upper ribs. The respiratory effect of the lower rib displacement, however, is uncertain. In the present study, two sets of experiments were performed in dogs to assess this effect. In the first, all the inspiratory intercostal muscles were severed, so that the diaphragm was the only muscl...

Introduction The thoracic cage is made up of twelve vertebrae, sternum and twelve pairs of ribs. The ribs articulate with the vertebrae posteriorly and with the sternum through the corresponding costal cartilages anteriorly. The spaces between the adjacent ribs are called intercostal spaces. There are 11 intercostal spaces on each side. The intercostal spaces are filled with three layers of int...

The purpose of this case study was to present the effectiveness physiotherapeutic treatment based on manual orthopedic techniques in an amateur athlete with costochondritis due physical strenuous exercise. A 31 years old experienced, well-trained, endurance presented chest pain suggesting after and kinetic examination. Patient reported effort last two weeks (combination mountain biking, route c...

Examined bones were obtained from eight adult African giant rats, Cricetomys gambianus Waterhouse. Animals used had an average body mass of 730.00 ± 41.91 gm and body length of 67.20 ± 0.05 cm. The vertebral formula was found to be C7, T13, L6, S4, Ca31-36. The lowest and highest points of the cervicothoracic curvature were at C5 and T2, respectively. The spinous process of the axis was the lar...

Cryptocleidoid plesiosaurs from the Upper Jurassic are well known from the Oxford Clay (Callovian) of the United Kingdom. The plesiosaurs of the nearly coeval Sundance Formation (Oxfordian) of North America are poorly known, but are thought to include two cryptocleidoid taxa: Pantosaurus striatus and Tatenectes laramiensis. Here we present two specimens recently recovered from the Bighorn Basin...

the effects of ethanolic and aqueous extracts of rheum ribs l. (rr) of the family polygonaceae was studied on serum cholesterol concentration in rabbits. to induce hypercholesterolemia, 0.5 g/kg/day of pure cholesterol powder was given orally to each rabbit for two weeks then cholesterol was halved and each group of animals was treated with a different regimen for another two weeks. both the et...

BACKGROUND The Late Cretaceous titanosauriform sauropod Huabeisaurus allocotus Pang and Cheng is known from teeth and much of the postcranial skeleton. Its completeness makes it an important taxon for integrating and interpreting anatomical observations from more fragmentary Cretaceous East Asian sauropods and for understanding titanosauriform evolution in general. METHODOLOGY/PRINCIPAL FINDI...
