The reliability of load-bearing structures is normally secured through codes, a competent structural design and proper execution inspection. Alternatively, the can be obtained via skilled test loading, which feasible technique both in construction new verification existing ones. Although current codes lack instructions for they are, however, used special cases; example, when doubtful due to def...

This paper investigates the effect of loading level and loading rate on the damage development and strength on the asphalt mixtures tested at three low temperatures. The current AASHTO specification for asphalt mixture low-temperature characterization consists of two tests: the indirect tensile creep (ITC) test and the indirect tensile strength (ITS). In the ITC, the load was applied until the ...

Metallic Magnesium (Mg) and its alloys are highly suitable for medical applications as biocompatible and biodegradable implant materials. Magnesium has mechanical properties similar to bone, stimulates bone regeneration, is an essential non-toxic element for the human body and degrades completely within the body environment. In consequence, magnesium is a promising candidate as implant material...

Magnesium has recently been explored as important mineral for the health of CF patients. The aim was detect the rates of hypomagnesaemia and to compare the serum magnesium of the CF patients treated in a reference center for CF. Methods: It was a retrospective study, survey of patients’ records treated in a reference center for CF. It was included the first dosage of serum magnesium collected f...

We demonstrated similar plasma concentrations and urinary losses but lower erythrocyte magnesium concentrations (2.18 +/- 0.04 vs 1.86 +/- 0.03 mmol/L, P less than 0.01) in twelve aged (77.8 +/- 2.1 y) vs 25 young (36.1 +/- 0.4 y), nonobese subjects. Subsequently, aged subjects were enrolled in a double-blind, randomized, crossover study in which placebo (for 4 wk) and chronic magnesium adminis...

Hypocalcemia and resistance to exogenous parathyroid hormone have been reported in several clinical states associated with magnesium deficiency. On the basis of such observations, it has been suggested that magnesium depletion per se may result in impaired responsiveness of the adenyl cyclase-adenosine 3',5'-monophosphate (3',5'-AMP) system. To test this hypothesis, 4 wk old male parathyroidect...

The advancement of the biological production of nanoparticles using herbal extracts performs a significant role in nanotechnology discipline as it is green and does not engage harsh chemicals. The objective of the present investigation was to extract flavonoids in the mode of apple extract and synthesize its silver nanoparticles and ultimately nanoparticles loading into hydrogels. The presence ...
