National Transonic Facility status

The National Transonic Facility (NTF) was operational in a combined checkout and test mode for about 3 years. During this time there were many challenges associated with movement of mechanical components, operation of instrumentation systems, and drying of insulation in the cryogenic environment. Most of these challenges were met to date along with completion of a basic flow calibration and aerodynamic tests of a number of configurations. Some of the major challenges resulting from cryogenic environment are reviewed with regard to hardware systems and data quality. Reynolds number effects on several configurations are also discussed

Pupil participation in Scottish schools: how far have we come?

The United Nations Convention on the Rights of the Child (UN, 1989), which applies to all children under the age of 18, established the overarching principles guiding pupil participation. In most European states, signatories to the Convention have enacted policies to promote the voice of the child or young person in decisions that affect them. In education systems strategies to enhance the pupil participation are an increasing feature of deliberation on education for citizenship, curriculum flexibility, pedagogical approaches and assessment for learning. Despite the positive policy context and professional commitment to principles of inclusion, translating policy intentions so that the spirit of the legislation is played out in the day-to-day experiences of pupils is a constant challenge. This article reports on research that examines how pupil participation is understood and enacted in Scottish schools. It considers how the over-laying of diverse policies presents mixed messages to practitioners

Low-Value &(and) Predictably Small: When Should Class-Arbitration Waivers be Invalidated as Unconscionable

In Muhammad v. County Bank of Rehoboth Beach, the New Jersey Supreme Court chose the interests of consumers over liberally construed Federal Arbitration Act (FAA) policies in deciding that a no class-arbitration provision contained within a payday loan contract was unconscionable. The court used state law contract principles to invalidate the clause, finding that the clause violated several state public policies. Particularly important to the court was the fact that individual claims for damages would be nominal, and thus individual vindication of statutory rights would prove too costly to be practical. In making this distinction, the court suggested a preference for protecting individuals who have entered into contracts of adhesion with little or no chance of protecting themselves outside of the availability of the class mechanism. The court\u27s decision may serve as a guidepost for other jurisdictions attempting to shape the law in the undefined arena of class-arbitration waivers. The court signals that freedom to contract under the FAA is important, but not at the expense of protecting individual claimants and the statutory rights of consumers

Environmental measurements in swine confinement housing

In this study, air quality measurements were made in swine production confinement facilities to monitor the internal environment. Two buildings were monitored throughout most of this study. The two buildings were identical except for the use of a pit ventilation system in one of the buildings (Bam B). The main focus of the monitoring system used in this study consisted of electrochemical gas sensors to continuously measure gas concentration levels (ppm) at human level (2 m). The gases measured were Oxygen, Carbon Monoxide, and Ammonia and Hydrogen Sulfide, which are the major gases of concern. Other measurements included that of environmental conditions, such as temperature, relative humidity, and solar radiation, and other key factors affecting gas levels, including monitoring the building\u27s ventilation system. Data were averaged over each 30-minute period and recorded by a data logger. These data were then transmitted by the use of a cellular communication/modem system to the department at the university, which was located more than 300 miles away from the research site. Results obtained from this study found the major manure gases, ammonia and hydrogen sulfide, to be consistently lower in the pit ventilated building (Bam B) when compared to the non-pit ventilated building (Bam A). Gas levels were monitored over two successive winters, when ventilation levels were at their lowest due to environmental conditions. Significant differences (p \u3c 0.05) were found between gas levels taken in the two buildings and levels were found to change, most of the time, inversely proportional to that of temperature. Gas levels were found to be directly affected by ventilation levels during cold weather, as found when monitoring the ventilation operating frequency. As ventilation levels were decreased in response to cold weather, gas levels increased due to accumulations of levels within the closed unit and vice/versa. Measurements were also taken at the pit exhaust and inside the pit ventilated Bam B. As expected, levels of ammonia and hydrogen sulfide were found to be significantly higher (p \u3c 0.05) at the pit exhaust area when compared to levels taken inside. These measurements were taken during the warm summer months, when ventilation rates were high; and gas levels were found to be directly proportional to temperature. Measurements were also taken at animal level to see if there were differences in gas concentrations between animal and human (2 m) level. Slight differences were found between the two areas of measurement, but reliable conclusions cannot be made about why differences occurred between high and low measurements because of the inconsistent data collected. Overall, the environments within the swine confinement units were found to be very cyclical and dependent upon environmental conditions and changes in ventilation. The use of a pit ventilation system was found to be beneficial in the control of manure gases, especially during periods of cold weather, when ventilation rates were low

Canard-wing lift interference related to maneuvering aircraft at subsonic speeds

An investigation was conducted at Mach numbers of 0.7 and 0.9 to determine the lift interference effect of canard location on wing planforms typical of maneuvering fighter configurations. The canard had an exposed area of 16.0 percent of the wing reference area and was located in the plane of the wing or in a position 18.5 percent of the wing mean geometric chord above the wing plane. In addition, the canard could be located at two longitudinal stations. Two different wing planforms were tested: one with a leading-edge sweep angle of 60 deg and the other with a leading-edge sweep angle of 44 deg. The results indicated that although downwash from the canard reduced the wing lift at angles of attack up to approximately 16 deg, the total lift was substantially greater with the canard on than with the canard off. At angles of attack above 16 deg, the canard delayed the wing stall. Changing canard deflection had essentially no effect on the total lift, since the additional lift generated by the canard deflection was lost on the wing due to an increased downwash at the wing from the canard

Prolonged QT Syndrome and Seizure Secondary to Alkaline Earth Metal Deficiency: A Case Report

Introduction. Alkaline earth metal deficiency is recognized as a cause of both seizure and long QT syndrome. Their deficiency can have significant repercussions on the function of cells, tissues, and organs of the body. An understanding of the role of electrolytes allows an appreciation of the significance of depleted levels on cell function. Case Report. A 65-year-old lady was admitted with symptoms of chest discomfort, vomiting, increased stoma output, and dizziness. Two days following admission she suffered a tonic-clonic seizure. ECG review demonstrated a prolonged QTc interval, raising the possibility of an underlying Torsades de Pointes as the precipitant. This was attributed to electrolyte disturbance arising as a result of multiple aetiologies. Discussion. This paper highlights the multisystem effects of electrolyte disturbance, with emphasis upon its role in precipitating cardiac arrhythmia and neurological symptoms
