Basic Arkansas Intestate Succession, Rights of Surviving Spouses, and Related Curative Techniques for Lawyers and Landmen

Mineral interests may lay dormant for decades before becoming productive. In the interim, however, the owners of these interests do not lay dormant. They live long lives, marry, have children, and eventually, they die. Some of these persons have well-laid estate plans, know the nature and extent of their property, and upon their departure to the hereafter, leave their affairs in meticulous order with no question of who is entitled to what and where. Others depart this life leaving little more than a treasure map and their descendants. Generations and many lines of persons descended from one severed mineral owner repeat the cycle of life—marriage, children, and death with or without consideration for what happens to their property upon their passing. Over many generations with such variations in the handling of final affairs among members of a family, the ownership of the original mineral owner’s interest today can resemble a bowl of spaghetti

Serum parathyroid hormone levels and renal handling of phosphorus in patients with chronic renal disease

In eight patients with advanced renal insufficiency (inulin clearance 1.4-9.1 ml/min), concentrations of serum calcium (S[Ca]) and phosphorus (S[P]) were maintained normal (S[Ca] > 9.0 mg/100 ml, (S[P] < 3.5 mg/100 ml) for at least 20 consecutive days with phosphate binding antacids and oral calcium carbonate. The initial serum levels of immunoreactive parathyroid hormone (S-PTH) were elevated in three (426-9230 pg/ml), normal in four (one after subtotal parathyroidectomy), and not available in one. The initial fractional excretion of filtered phosphorus was high in all and ranged from 0.45-1.05. Following sustained normo-calcemia and normo-phosphatemia, S-PTH was reduced below control levels in all patients; being normal in six and elevated in two. decreased below control levels in all patients; it remained high in six (of which five had normal S-PTH) and was normal in two (of which one had elevated S-PTH). The observed relationship between S-PTH and could either reflect the inability of the radioimmunoassay for PTH employed to measure a circulating molecular species of PTH which was present in which case the actual levels of S-PTH were higher than those measured, and/or it could be indicative of the presence of additional important factor(s) (other than S-PTH) which inhibit tubular reabsorption of phosphorus in advanced chronic renal failure. © 1972 by The Endocrine Society

Acute effect of prednisolone on renal handling of sodium.

The effect of prednisolone on renal handling of sodium (Na) was studied in rats under three experimental conditions: 1) hydropenia, 2) water diuresis, and 3) distal tubular blockade (DTB). Prednisolone, 0.25 mg/100 g per hr, was infused directly into left renal artery and urine was collected separately from each kidney. Predominantly unilateral increases in urine flow (V) and Na excretion were noticed in all experiments during prednisolone infusion. In the hydropenic rats the maximal increments on the infused side were, for V (mean ± SD), from 9.3 ± 1.5 to 21.4 ± 0.8 μl/min (P < 0.001); for C(Na)/C(In), from 0.28 ± 0.11 to 2.97 ± 0.71 % (P < 0.005); and for [Formula: see text] , from 2.93 ± 2.26 to 5.32 ± 1.92% (P < 0.05). In the rats with water diuresis, the maximal increases were, for V/C(In), from 5.87 ± 1.97 to 10.1 ± 6.0% (P < 0.005); for C(H(2)O)/C(In), from 4.09 ± 0.68 to 6.00 ± 0.44% (P < 0.0005); and for C(Na)/C(In), from 0.22 ± 0.07 to 0.70 ± 0.38% (P < 0.01). In DTB-rats the maximal increases were for V from 48.6 ± 9.0 to 72.7 ± 14.1 μl/min (P < 0.0005) and for C(Na)/C(In) from 9.42 ± 2.97 to 20.23 ± 7.34% (P < 0.005). In the contralateral kidney these changes were less pronounced. These observations suggest that prednisolone depresses directly Na reabsorption. The association of natriuresis with augmented [Formula: see text] and C(H(2)O)/C(In) during hydropenia and water diuresis, respectively, and the increases in V and C(Na)/C(In) during DTB, all are consistent with inhibition of Na reabsorption in the proximal tubule

Apportioning Liability in Maryland Tort Cases: Time to End Contributory Negligence and Joint and Several Liability

The Article presents a comprehensive proposal for assigning liability in tort cases according to the parties’ respective degrees of fault. The authors criticize the Court of Appeals of Maryland’s recent decision in Coleman v. Soccer Association of Columbia declining to abrogate contributory negligence, particularly the court’s notion that it should not act because of the legislature’s repeated failure to do so. The Article provides a comprehensive analysis of the advantages and disadvantages of comparative fault, including its effect on administrative costs, claims frequency, claims severity, insurance premiums, and economic performance. The authors propose the legislative enactment of comparative fault and debate the respective advantages of its pure and modified forms. The Article then provides a comprehensive roadmap for the implementation of a comparative fault system and addresses the handling of multiple and absent tortfeasors and how the implementation of comparative fault should affect the law governing last clear chance, assumption of risk, and intentional wrongdoing. Because the authors’ approach is one of apportioning liability according to fault, they then recommend abrogating other Maryland doctrines that refuse to apportion liability, including joint and several liability and the state’s statute that declares evidence of seat belt nonuse inadmissible

Cost benefit analysis of space communications technology: Volume 1: Executive summary

The questions of (1) whether or not NASA should support the further development of space communications technology, and, if so, (2) which technology's support should be given the highest priority are addressed. Insofar as the issues deal principally with resource allocation, an economics perspective is adopted. The resultant cost benefit methodology utilizes the net present value concept in three distinct analysis stages to evaluate and rank those technologies which pass a qualification test based upon probable (private sector) market failure. User-preference and technology state-of-the-art surveys were conducted (in 1975) to form a data base for the technology evaluation. The program encompassed near-future technologies in space communications earth stations and satellites, including the noncommunication subsystems of the satellite (station keeping, electrical power system, etc.). Results of the research program include confirmation of the applicability of the methodology as well as a list of space communications technologies ranked according to the estimated net present value of their support (development) by NASA
