Acrylonitrile process enhancement through waste minimization: Effect of reaction conditions and degree of backmixing
( MDPI AG , 2021 , Article)Waste minimization in reactor design is an effective approach for pollution control, when compared to the traditional practice of the end-of-pipe treatment. Reactor degree of backmixing and operating conditions are important ... -
Action recognition in poor-quality spectator crowd videos using head distribution-based person segmentation
( Springer Verlag , 2019 , Article)Despite a big volume of research on action recognition, little attention has been given to individual action recognition in poor-quality spectator crowd scenes. It is an important scenario, because most of the surveillance ... -
Action Recognition in Spectator Crowds
( Hamad bin Khalifa University Press (HBKU Press) , 2016 , Conference Paper)Action Recognition in Spectator Crowds During the Football Association competitions held in 2013 in UK, 2,273 people were arrested due to the events of lawlessness and disorder, according to the statistics collected by ... -
Activated carbon-doped polystyrene fibers for direct contact membrane desalination
( Springer Nature , 2020 , Article)Membranes for direct contact membrane distillation were produced from electrospun polystyrene microfibers doped with activated carbon. The addition of activated carbon reduced the hydrophobicity of the fibers. Therefore, ... -
Activation and Contraction of Human “Vascular” Smooth Muscle Cells Grown From Circulating Blood Progenitors
( Frontiers Media , 2021 , Article)Blood outgrowth smooth muscle cells (BO-SMCs) offer the means to study vascular cells without the requirement for surgery providing opportunities for drug discovery, tissue engineering, and personalized medicine. However, ... -
Activation and stabilization of gallium arsenide anode in an aqueous photoelectrochemical cell
( Elsevier B.V. , 2003 , Article)The formation of a porous layer on the surface of gallium arsenide anode, n-GaAs, increases photogenerated currents significantly. This layer was formed as a result of an anodic polarization of illuminated n-GaAs in acidified ... -

Activation Dynamics and Immunoglobulin Evolution of Pre-existing and Newly Generated Human Memory B cell Responses to Influenza Hemagglutinin.
( Elsevier , 2019 , Article)Vaccine-induced memory B cell responses to evolving viruses like influenza A involve activation of pre-existing immunity and generation of new responses. To define the contribution of these two types of responses, we ... -
Activation of K7 channels with the anticonvulsant retigabine alleviates neuropathic pain behaviour in the streptozotocin rat model of diabetic neuropathy.
( Taylor & Francis (Routledge) , 2019 , Article)Diabetic peripheral neuropathy (DPN) is the most incapacitating complication of diabetes mellitus. Up to 50% of patients with DPN develop peripheral neuropathic pain (PNP). The underlying ionic and molecular mechanisms of ... -
Activation of kaolin with minimum solvent consumption by microwave heating
( Mineralogical Society , 2014 , Article)A kaolin clay was activated with 1.0 M H2SO4 solution at minimum liquid to solid ratio (L/S) using microwave heating. The optimum experimental conditions for activation were L/S ratio 3.0 mL 1 M H2SO4 per gram kaolin, ... -
Activation of pruritogenic TGR5, MRGPRA3, and MRGPRC11 on colon-innervating afferents induces visceral hypersensitivity
( American Society for Clinical Investigation , 2019 , Article)Itch induces scratching that removes irritants from the skin, whereas pain initiates withdrawal or avoidance of tissue damage. While pain arises from both the skin and viscera, we investigated whether pruritogenic irritant ... -
