Contributory Negligence of a Minor As a Matter of Law in Missouri

With respect to the degree of care which must be exercised by a child, for purposes of determining whether lie is guilty of negligence or contributory negligence, the general rule is stated that he must conform to that standard of conduct to be expected of a child of similar age, experience and intelligence. While it may be said that the courts of Missouri are generally in accord with this rule, the cases have varied widely in the application thereof. As a matter of fact, it has been admitted by the Supreme Court of Missouri that the Missouri cases involving the issue of contributory negligence of a minor as a matter of law are in irreconcilable conflict.” With this in mind, the maxim that each case must be decided upon its own facts seems particularly appropriate to the determination of whether a minor has, in a given case, been contributorily negligent as a matter of law. However, to facilitate analysis of the Missouri cases, they should be classified at least according to the general types of factual situations involved therein. This Article will attempt to make such an analysis, and, to that end, will be based upon a classification involving the following four general categories: (1) Cases involving minors who were injured in rail crossing accidents; (2) Attractive nuisance cases; (3) Cases in which minors were injured as a result of their employment, usually while operating machinery; and (4) Cases where minors and adults were injured while in the attempt to alight from public carriers

Construction of the Saturn Launch Facilities

IN THE RACE for the moon, the Saturn rocket system is carrying the colors of our country. This rocket system is composed of parts that come from localities spread throughout the United States; however, the payoff window is at Cape Canaveral. It is there that all the various systems, scientists, astronauts, engineers, and dollars combine to work together to launch, first experimental probes, then orbital missions and unmanned surveys of the moon and other planets followed by the culmination for this decade-manned lunar landing and return to earth. A vital part of the entire complicated, far reaching program is the construction work required to produce the exotic facilities that are used by the NASA scientists and engineers to launch these giant rockets. This construction work is made up of the simple and commonplace, such as clearing the palmettos with bulldozers to the difficult and complex, such as fabricating a 6000 pound test pipe line made of a new type of bimetalic pipe to carry nitrogen or helium gas

Structural Defects in Poly(vinyl chloride) and the Mechanism of Vinyl Chloride Polymerization: Comments on Recent Studies

Investigations in the title areas within the past ten years are summarized and critiqued. The polymerizations studied were performed by conventional free-radical methods. A new mechanism, not yet confirmed, is suggested to explain a reported enhancement in the chloromethyl branch concentration of poly(vinyl chloride) (PVC) prepared at high conversions of monomer. This mechanism involves an intramolecular 1,5 hydrogen shift in a 1,3,5,6-tetrachlorohexyl radical. Evidence showing that most of the internal double bonds in PVC are not formed via intermolecular H abstraction from internal monomer units is tentatively rationalized, in part, by hydrogen transfer via at least one cyclic transition state containing more than eight members. The absence of free chlorine atoms from polymerizations of vinyl chloride (VC) is reaffirmed, and the copolymerization of VC with the chloroallylic chain ends of PVC is argued to be insignificant. New information in the literature does not invalidate the currently accepted mechanism of vinyl chloride polymerization. (c) 2012 Published by Elsevier Ltd

Neutrophil Reverse Migration Becomes Transparent with Zebrafish

The precise control of neutrophil-mediated inflammation is critical for both host defense and the prevention of immunopathology. In vivo imaging studies in zebrafish, and more recently in mice, have made the novel observation that neutrophils leave a site of inflammation through a process called neutrophil reverse migration. The application of advanced imaging techniques to the genetically tractable, optically transparent zebrafish larvae was critical for these advances. Still, the mechanisms underlying neutrophil reverse migration and its effects on the resolution or priming of immune responses remain unclear. Here, we review the current knowledge of neutrophil reverse migration, its potential roles in host immunity, and the live imaging tools that make zebrafish a valuable model for increasing our knowledge of neutrophil behavior in vivo

The Effects of Selected Work Intervals of Eccentric Exercise During a Strength Training Program

The purpose of this study was to compare the effects of six- and twelve-second time intervals of eccentric strength training among college males. Thirty-eight students were used in two experimental groups and one control group. Subjects in the two experimental groups trained three days a week for seven consecutive weeks and were required to perform two sets -of eccentric exercise with three repetitions in each set for either six- or twelve-second intervals, depending upon the experimental group assignment. Results indicated that there was a significant differ ence between the experimental groups' mean strength gain and that of the control group. There was no significant difference between the two experimental groups
