“…Here, the quantities on the left-hand-side of Eqs. (18)(19)(20) are surface weighted average of the corresponding nuclear matter quantities with local density approximation, which have been determined within the method of Brueckner et. al., [50,51].…”

Starting from light to superheavy nuclei, we have calculated the effective surface properties such as the symmetry energy, neutron pressure, and symmetry energy curvature using the coherent density fluctuation model. The isotopic chains of O, Ca, Ni, Zr, Sn, Pb, and Z = 120 are considered in the present analysis, which cover nuclei over the whole nuclear chart. The matter density distributions of these nuclei along with the ground state bulk properties are calculated within the spherically symmetric effective field theory motivated relativistic mean field model by using the recently developed IOPB-I, FSUGarnet, and G3 parameter sets. The calculated results are compared with the predictions of the widely used NL3 parameter set and found in good agreement. We observe a few signature of shell and/or sub-shell structure in the isotopic chains of nuclei. The present investigations are quite relevant for the synthesis of exotic nuclei with high isospin asymmetry including superheavy and also to constrain an equation of state of nuclear matter.

“…The nuclear symmetry energy is a quantity of crucial importance in different areas of nuclear physics, including structure of ground-state nuclei [1][2][3], dynamics of heavy-ion reactions [4][5][6], physics of giant collective excitations [7] and physics of neutron stars [8][9][10]. Recently, the interest in the symmetry energy has been stirred up by novel astrophysical observations and by the availability of exotic beams in accelerators that provide additional information to the standard nuclear asymmetry studies based on stable nuclei.…”

We study the correlation between the thickness of the neutron skin in finite nuclei and the nuclear symmetry energy for isotopic chains of even-even Ni, Sn, and Pb nuclei in the framework of the deformed self-consistent mean-field Skyrme HF+BCS method. The symmetry energy, the neutron pressure and the asymmetric compressibility in finite nuclei are calculated within the coherent density fluctuation model using the symmetry energy as a function of density within the Brueckner energy-density functional. The mass dependence of the nuclear symmetry energy and the neutron skin thickness are also studied together with the role of the neutron-proton asymmetry. A correlation between the parameters of the equation of state (symmetry energy and its density slope) and the neutron skin is suggested in the isotopic chains of Ni, Sn, and Pb nuclei.

“…This energy range also provides an opportunity to explore the transition from quasi-fission to multi-fragmentation. Recent theory [3][4][5][6][7] has suggested interesting reaction dynamics via deformations of the reaction system and few body breaking of the deformed, primary reaction partners.…”

Hypertension presenting with metabolic alkalosis with hypokalemia is not uncommon. In this analysis, we present the management of such a scenario in white and black patients. Six patients (white¼4 [1 females, 2 males, age¼24-62]; blacks¼2 [1male, 1 female, age¼32, 40]) with hypokalemia (2.9-3.3 mEq/L), metabolic alkalosis (28-32 mm Eq/L) and hypertension (155-180/90-105 mmHg) were seen in hypertension clinic. All had a BMI of >32 and metabolic syndrome. None had clinical evidence of sleep apnea. All had been on adequate dosage of at least three BP meds (calcium channel blocker, ACE-I/ARB, metoprolol/carvedilol). All had a negative Doppler ultrasound for renal artery stenosis. Their serum aldosterone to renin ratio was 15-18 (normal¼less than 20). Urinary aldosterone in the six patients ranged from 10-12 ng/l (reference abnormal¼>14 ng/dl). Because of normal aldosterone to renin ration, CT scan was not obtained in these patients. Nonetheless, considering obesity and aldosterone production by adipocytes (high normal urinary aldosterone), treatment with spironolactone/eplerenone was initiated with normalization of blood pressure in 3/4 whites (<140/90 mmHg). The non-responder (white female age 62) was treated with amiloride with subsequent control of BP to <140/90 mmHg. Two black patients also responded better to amiloride compared to spironolactone/eplerenone bring them to the goal (<140/90 mmHg). While aldosterone is an important mediator of hypertension in obese individuals, over-activity of sodium channel in the distal tubule (ENaC) must be considered in the management uncontrolled hypertension with hypokalemic metabolic alkalosis, particularly in blacks. It has been suggested before that amiloride provides better BP control in resistance hypertension in blacks compared to white patients providing validity to ENaC over-activity. Genetic testing was not performed in our cohort to investigate the presence of Liddle's syndrome.
