Synovial joints are the lubricated connections between the bones of our body that are commonly affected in arthritis. It is assumed that synovial joints first evolved as vertebrates came to land, with ray-finned fishes lacking lubricated joints. Here, we examine the expression and function of a critical lubricating protein of mammalian synovial joints, Prg4/Lubricin, in diverse ray-finned fishe...

This paper outlines a mathematical modelling approach to predict the steady-state behaviour of finned-coil evaporators. The model was built taking three domains into account: (i) refrigerant flow inside the coil; (ii) heat transfer through the walls; and (iii) air flow through the finned-coil array. The equations were obtained from the mass, momentum and energy conservation principles, mathemat...

S. Gil, J. Ochman, W. Bialik, Faculty of Materials Engineering and Metallurgy, Silesian University of Technology, Katowice, Poland This paper provides results of thermal investigations on pipes with outer transverse fins produced by placing a strip, being a form of helical spring which functions as a radiator, on the basis pipe. The investigations were carried out at the facility that enables m...

The efficiency of PV (photovoltaic) modules is highly dependent on the operating temperature. objective this work to enhance performance by passive cooling using aluminum fins that have been nanocoated (like those an automobile radiator). A rise in cell temperature module leads a decrease its performance. As result, effective mechanism required. In work, has improved natural convection, which w...

Increased concerns about climate change and day by day increment in energy cost has created the importance of Refrigeration & Air Conditioning system with high COP. COP of a Vapour Compression Refrigeration system is mainly influenced by the effectiveness of the Heat Exchanger being Employed. Optimization in the design of Heat Exchanger is highly desirable to improve their effectiveness and red...

Abstract Ray-finned fishes comprise nearly half of extant vertebrate species and include several ancient lineages with fossil records that stretch over 200 Myr in time. One these old clades, the sturgeons paddlefishes, is distributed across Northern Hemisphere includes some largest known freshwater fishes. Yet, record this lineage (Acipenseriformes) poor compared to similarly ray-finned fish cl...

This paper presents how the thermal performance of an existing finned-tube heat exchanger is determined experimentally. In the experiment, heat is transferred from an exhaust gas stream to a thermal oil. The experimental setup is discussed including the thermal fluid selection process, the components, instrumentation and resultant measurement uncertainty. The heat transfer is calculated individ...

A long-finned pilot whale with morbilliviral disease was stranded in New Jersey. An immunohistochemical stain demonstrated morbilliviral antigen. Reverse transcriptase-polymerase chain reaction for morbillivirus P and N genes was positive. Novel sequences most closely related to, but distinct from, those of dolphin and porpoise morbilliviruses suggest that this virus may represent a third membe...
