Graphene and its magnetite derivative were used as adsorbents for removal of emulsified oil from produced water. The experimental parameters for maximum emulsified oil removal efficiency and effective regeneration of these adsorbents were determined. The best parameters in terms of dosage, contact time, pH, salinity and temperature were 3.00 g/L, 60.0 min, 10.0, 1500 ppm and 25.0 °C for graphene nanoplatelets, and 4.00 g/L, 30.0 min, 3.5, 1000 ppm and 25.0 °C, for graphene magnetite, respectively. ...

For pt. I see abstr. A43970 of 1973. The solution of the integral equation which arises in the self-consistent theory of localization has been explored for a Cauchy distribution of site energies, for a uniform distribution, and for a binary alloy, with particular attention to the behaviour of the localization edge in the case of weak disorder, when it is close to the unperturbed band edge. The solution could be calculated because an exact solution is found in the limit of zero disorder, and because ...

A new basis has been found for the theory of localization of electrons in disordered systems. The method is based on a selfconsistent solution of the equation for the self energy in second order perturbation theory, whose solution may be purely real almost everywhere (localized states) or complex everywhere (nonlocalized states). The equations used are exact for a Bethe lattice. The selfconsistency condition gives a nonlinear integral equation in two variables for the probability distribution of the ...

The diagnosis of thyroidal hemiagenesis was established through the administration of thyroid stimulating hormone and a thyroid scintiscan. T3 thyrotoxicosis is a previously unreported clinical presentation of thyroid hemiagenesis.

Obese patients are characterised by several neuroendocrine abnormalities, including characteristically a decrease in growth hormone responsiveness to GH-releasing hormone. In normal subjects, the GH response to GHRH is enhanced by the acetylcholinesterase inhibitor, pyridostigmine. We have studied the effect of this drug on GH secretion in gross obesity. Twelve obese patients were studied (mean weight 156% of ideal) and compared with a group of 8 normal volunteers. Each subject was initially studied ...

This study aimed to estimate the prevalence of inadequate glycaemic control and its correlates in a large multicentre survey of Brazilian patients with diabetes. A cross-sectional study was conducted in a consecutive sample of patients aged 18 years or older with either type 1 or type 2 diabetes, attending health centres located in ten large cities in Brazil (response rate = 84%).

There is a significant association between insulin resistance and low cardiorespiratory fitness in nondiabetic subjects. In a population with risk factors for type 2 diabetes (T2DM), before they are insulin resistant, we investigated low exercise capacity (VO2max) as an early marker of impaired insulin sensitivity in order to determine earlier interventions to prevent development of insulin resistance syndrome (IRS) and T2DM. Cross-sectional analyses of data on 369 (78 men and 291 women) people at risk ...

During hypoxia, active substances released by the endothelium play a key role in the cardiovascular and respiratory responses elicited to optimize oxygen delivery. As hypercholesterolemia is a major cause of endothelial dysfunction, it may interfere with these responses.We studied cardiovascular and ventilatory responses to acute systemic hypoxia in 14 patients with hypercholesterolemia (HC) and 13 control (CO) subjects. Oxygen saturation decreased similarly in both groups. Diastolic blood pressure ...
