During the brazing of aluminum-based heat exchangers, the flux dry-off temperature plays a crucial role to get sound joints with maximum strength. In the present study, the NOCOLOK® flux consists of two phases of K2AlF5.H2O and KAlF4 with a melting point around 580 °C was used for brazing AA3003 as base metal with a clad-coating of AA4343 as filler metal. The slurry was applied on the joints an...

fracture mapping of late permian-early triassic flat-lying sedimentary rocks in the sydney basin,new south wales, australia, shows that joints developed originally in extension were faulted in subsequentevents. joints with a regional distribution fall into two (early and late) formed groups. group i joints propagatedhorizontally and never interfered with each other. these joints were subsequent...
Objective (s):Rheumatoid arthritis (RA) is a chronic systemic inflammatory disorder, primarily targeting the synovium and articular cartilage that leads to joint damage. Recent reports have suggested the role of adipocytokines in mediating joint damage; however it still is a matter of debate. The purpose of this study was to evaluate the association between serum values of adiopocytokines (lept...
A 44-year-old diabetic man with isolated septic arthritis of the left acromioclavicular joint (A-C) caused by Staphylococcus aureus is described. He was admitted to the Department of Rheumatology with clinical symptoms of left shoulder arthritis and fever. Laboratory findings showed leukocytosis, elevated levels of erythrocyte sedimentation rate and C-reactive protein, all indicating septic art...
In this study, corrosion behavior of Ti-6Al-4V titanium alloy joint by friction stir welding with a rotational speed of 375 rpm and a travel speed of 100 mm/min was investigated. The welding procedure was carried out under β-transus temperature that was consisted of equiaxed grains in the stir zone. The corrosion behavior of the welded joint was investigated in 3.5% NaCl solution at temperature...

In this paper, the discussion concerning the joint use of unit root and stationarity tests is extended to the case of cointegration. Critical values for testing the joint confirmation hypothesis of no cointegration are computed and a small Monte Carlo experiment evaluates the relative performance of this approach.
introduction: there are some internal and external factors in the development and supporty of joint. the role of movement on foint development could be study in three methods. in vitro limb buds culture limb bud graft to coelomic membrance. neuromuscular function block. the development of the fourth metatarsophalyngeal joint of swiss mice was studied in normal circumstances and the absence of m...
