Corrosion inhibitors play a major role in the cost effective control of corrosion. Because of the toxic nature and high cost of chemicals plant extracts are currently used as inhibitors. In the current study, efforts are taken to study the role of seed extracts of Phaseolus aureus on corrosion of mild steel in 1M HCl by weight loss method and potentiodynamic polarization technique. The Potentio...

ABSTRACT The reproductive biology of thresher shark species the Ecuadorian Pacific was analysed based on 1236 specimens Alopias pelagicus (711 females and 525 males) 354 A. superciliosus (164 190 landed in “Playita Mía”, from January to December 2019. length ranged between 67.2 184 cm PCL (precaudal length) males 69.0 178.4 PCL, registered a minimum maximum size 76.0 202.2 for 94.0 204.8 males....

A dedicated in-vacuum X-ray detector based on the hybrid pixel PILATUS 1M detector has been installed at the four-crystal monochromator beamline of the PTB at the electron storage ring BESSY II in Berlin, Germany. Owing to its windowless operation, the detector can be used in the entire photon energy range of the beamline from 10 keV down to 1.75 keV for small-angle X-ray scattering (SAXS) expe...

The goals of this study were to determine whether the long-term training regimens experienced by competitive collegiate swimmers would result in altered levels of total and free serum insulin-like growth factor I (IGF-I) as well as IGF-binding proteins (BP) IGFBP-1 and -3. Two male (Teams 1M and 2M) and one female (Team 2F) teams were studied at the start of training, after 2 mo of training, af...

This study investigates the impact of pressure overload on vascular changes after myocardial infarction (MI) in rats. To evaluate the effect of pressure overload, MI was induced in three groups: 1) left coronary artery ligation for 1 mo (MI-1m), 2) ischemia 30 min/reperfusion for 1 mo (I/R-1m), and 3) ischemia-reperfusion (I/R) was performed after pressure overload induced by aortic banding for...

Osteoporosis and periodontal disease (PD) are frequently associated in the elderly, both concurring to the loss of jaw alveolar bone and finally of teeth. Bisphosphonates improve alveolar bone loss but have also been associated with osteonecrosis of the jaw (ONJ), particularly using oncological doses of zoledronate. The effects and therapeutic margin of zoledronate on jaw bone therefore remain ...
