Oftentimes, knowledge about the background of authors can lead to a deeper and more thorough understanding of their work. Erin L. McCullough is a Postdoctoral Research Fellow at the Centre for Evolutionary Biology at the University of Western Australia (cite- https://www.researchgate.net/profile/Erin_Mccullough2). She was a PhD student at the University of Montana and has a recently updated blog in which her most recent papers and publications can be found (https://erinlouisamccullough.wordpress…

ABSTRACT The reactivity of acid base cements forming hydroxyapatite (HA) such as, β-tricalcium phosphate (β-TCP) and dicalcium phosphate dehydrate (DCPD). Amorphous calcium phosphates, prepared by precipitation from supersaturated solutions, can also react to form apatitic cements since they are thermodynamic unstable with respect to HA and have a setting reaction more independent of particle size. Calcium phosphate cement containing an antibiotic can be used for filling bone defects and to…

concentration of metal precursor, contact time and solution pH on the formation of AuNPs was evaluated to determine the optimum conditions for synthesis. As synthesized AuNPs were characterized by UV-Vis spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), energy dispersive X-ray analysis…

Your brain is permeated by a vast network of tiny little blood vessels, or capillaries as they are called. These are extremely small and thin so that blood cells can pass through them in a single file line. There are so many capillaries in one brain that you could lay them out and fill an average sized living room full of them. These capillaries that are located in the brain are surrounded by a single layer of cells. The layer of cells forms a type of barrier separating the capillaries and the…

[9]. The yield of microparticle was calculated by: Percentage yield =( Total wt.of formulation (g))/( Total wt.of drug +Total wt.of excipient) X100 Surface Morphology [10]: The morphology of the microparticle was determined with the aid of Scanning Electron…

Machining of GFRP laminate materials is difficult due to their anisotropic and non homogeneity in nature which consist of distinctly different phases, their response to machining. Machining of composite materials is rarely avoided in view of losing the strength of components due to interlayer fracture and delamination damage. In specific situations where metal inserts are inevitable in case of joining or affixing with other mating part, in this situation milling and drilling operations can’t be…

[53]. The direct band gap energy (Eg) of Tb3+: SA crystals grown by SEST and SR methods are found to be 4.20 eV, 4.10 eV respectively, which is in good accordance with the reported values [54]. The value of band gap of Sulfamic acid was found to decrease with increase in impurity concentration and it is found between 4 and 5 [54, 55]. Fig(7).

1. Introduction Silicified wood is normally formed close to the surface due to the infiltration of buried wood with mineral-rich water and the associated deposition of minerals (Kim et al., 2009). Two typical geological environments have been reported, 1) trees transported by streams and rivers then buried in the fluvial sediments (e.g., Weibel, 1996; Fielding and Alexander, 2001; Parrish and Falcon-Lang, 2007; Hartmann et al., 2010), and 2) ash from volcanic eruptions buries trees while felled…

Asthma and chronic obstructive pulmonary disease (COPD) are among the most common and prevalent diseases in the world (Raadhika and Shanthi, 2012; Rao and Kulkarni , 2012). Salbutamol sulphate (SS) is a short-acting β2-adrenergic receptor agonist used for the relief of bronchospasm (Sharma et al., 2015). Salbutamol sulphate is readily absorbed from the gastro intestinal tract following oral administration, and it undergoes the first pass metabolism in the liver. It requires multiple dosing a day…

“With increasing degree of calcification, the concentration of NaOH increases. The relationship between the concentration of NaOH and the factors in the calcified red mud liquor is given by three Equations (16–18): N_NaOH=1.29(N_1 m_1-N_2 (m_2-N_NaOH/1.29) (16) m2 = m1+m1N3 (17) r = 1000/m2…
