Swelling performance of sodium polyacrylate and poly(acrylamide-co-acrylic acid) potassium salt
Abstract The application of superabsorbent polymer hydrogels is gaining much research attention. Industrial applications include agriculture, environmental engineering, biomedical and tissue engineering, oilfield, construction and electrical
They were interviewed using a pretested validated questionnaire, and data were collected through direct face-to-face interviews using the incidental sampling method. It was found that physical appearance and mental alertness were the most
Polymers | Free Full-Text | A New Empirical Model for Viscosity of Sulfonated Polyacrylamide Polymers | HTML
Copolymers of acrylamide with the sodium salt of 2-acrylamido-2-methylpropane sulfonic acid—known as sulfonated polyacrylamide polymers—had been shown to produce very promising results in the enhancement of oil recovery,
a large volume of water allowing them to efficiently maintain smooth sliding interfaces while under high compressive loads. For hydrogels to be viable candidates to replace osteoarthritic cartilage, a study of their robust long-term use and
Bahraini uprising of 2011
Bahrain Tamarod. The Bahraini uprising of 2011 was a series of anti-government protests in Bahrain led by the Shia -dominant and some Sunni minority Bahraini opposition from 2011 until 2014. The protests were inspired by the unrest of the 2011
Benefits of using the method A schematic of a Dynamic Vapor Sorption (DVS) automated gravimetric sorption system is shown in Figure 1. The Surface Measurement Systems DVS instrument, now in use by many companies and research laboratories
BDNF reverses aging-related microglial activation | Journal of Neuroinflammation | Full Text
Interestingly, aging-related microglial activation could be reversed by chronic, subcutaneous perfusion of BDNF. Peripheral lipopolysaccharide (LPS) injection-induced microglial activation could be reduced by local supplement of BDNF, while
Most aging time of mineral plates is shorter than one week, while core plugs are often aged at least one week. Aging temperature of mineral plates and core plugs are distributed in 20–90 C and 44–100 C, respectively. A common practice has been
Intracellular Oxidant Activity, Antioxidant Enzyme Defense System, and Cell Senescence in Fibroblasts with Trisomy 21 - Hindawi
Another method of cell aging assessment in vitro was carried out using senescence-associated β-galactosidase activity (Figure 9(a)). SA- β -Gal-positive cells were counted (minimum 5 random fields and 50–100 cells/field) and the proportions of
Aims:Amid no current estimates or correlates of geriatric depression in Bahrain and support WHO campaign 2017 ‘Depression–let’s talk’, we aimed to assess the magnitude of

A method to evaluate the clot capture efficiency and capture location in inferior vena cava filters using synthetic polyacrylamide hydrogel clots, which were intended to simulate actual blood
Using the same research design, we reported that soleus muscle mass decreased with aging by 16% between young (8 months) and middle-aged (20 months) rats (5). CR reduced body weight in both young and middle-aged rats by 32%.
