We revisit the theory of Kondo effect observed by a scanning-tunneling microscope (STM) for transition-metal atoms (TMAs) on noble-metal surfaces, including $d$ and $s$ orbitals TMA, surface bulk conduction states metal, their hopping to tip STM. Fitting experimentally STM differential conductance Co Cu(111) both feature near Fermi energy resonance below band, we conclude that senses mainly orb...

noise induced hearing loss (nihl) is one of the most important occupational disease worldwide. nihl has been found potentiate by simultaneous carbon monoxide (co) exposure. free radicals have been implicated in cochlear damage resulted from the exposure to noise and due to the co hypoxia. this study examined whether α-tocopherol administration, as a free radical scavenger, causes the attenuatio...

The mechanism of the self-reaction of HCO radicals is investigated by using high-level quantum-chemical methods including M05-2X, CCSD, CCSD(T) and CRCC(2,3). Next, the rate coefficients for several product channels as a function of pressure and temperature are computed by employing statistical rate theories. Four important product channels are predicted to be CO + CO + H2, HCOH + OH, cis-(HCO)...

Ultramafic rocks of the ophiolitic complexes are prone to alteration and degradation, and therefore, ease of mobility of heavy metals such as nickel (Ni), chromium (Cr), cobalt (Co), lead (Pb), and vanadium (V), resulting in environmental hazards. The ultramafic rocks of the ophiolitic realm of Kurdistan province, west of Iran, show field and compositional evidence for such hazardous conditions...

Older people constitute the majority of high-risk surgical patients. Despite this, they are often excluded from patient and public involvement engagement (PPIE) research in perioperative setting. Comprehensive Geriatric Assessment (CGA)-based services demonstrate clinical cost effectiveness for older patients but not delivered at all hospitals. Scaling up such across NHS requires PPIE...

carbon monoxide (co) poisoning is still a health problem all over the world. informing users about symptoms and suggesting annual inspection of co producing devices will result in co poisoning reduction. the goal of this study was to evaluate awareness about co poisoning symptoms and its prevention ways in iranian population. in this study, a total of 700 patients' family members attended imam ...
