Orbiter thermal pressure drop characteristics for shuttle orbiter thermal protection system components: High density tile, low density tile, densified low density tile, and strain isolation pad

Pressure drop tests were conducted on available samples of low and high density tile, densified low density tile, and strain isolation pads. The results are presented in terms of pressure drop, material thickness and volume flow rate. Although the test apparatus was only capable of a small part of the range of conditions to be encountered in a Shuttle Orbiter flight, the data serve to determine the type of flow characteristics to be expected for each material type tested; the measured quantities also should serve as input for initial venting and flow through analysis

Are the Response Latencies of the Achilles and Patellar Reflex Responses as Recorded by the Action Current and Muscles Thickening Techniques Comparable?

Two techniques for the measurement of the latent times of the Achilles and the patellar tendon reflexes have become more or less standardized in recent years. These are: (1) the recording of the currents of action from the executant muscle; and (2) the recording of the thickening of the muscle itself

A Space Weather and Terrestrial Hazards Experiment for the MSTI Program

This paper discusses the instrumentation being built under BMDO auspices to construct a small, lightweight, low-cost satellite that provides measurements of local hazards affecting satellites in low-Earth orbit. In the following, we describe the objectives of the mission, the instrumentation being built and the mission profile for acquisition and utilization of the data products

Effect of a new antenatal care programme on the attitudes of pregnant women and midwives towards antenatal care in Harare

A clinical study on the importance of women participation and co-operation,them being a key stakeholder of any Antenatal Care (ANC) programme that may be introduced in Zimbabwe's health delivery system.Health providers have 'only recently been paying attention to the attitudes of women towards antenatal care programmes. Previously, the benefits of antenatal care (ANC) were considered so self evident that the consumers could not question how the services were delivered. However, the success of any ANC programme depends to a greater or lesser degree on the co-operation of the women. One of the aims of increased satisfaction with ANC is to achieve better compliance with the advice given, which may lead to improved pregnancy outcome. Satisfaction with the services, rather than the mere improvement of pregnancy outcome is also: now considered a goal in its own right

Value of Ascitic Lipids in the Differentiation between Cirrhotic and Malignant Ascites

Ascitic fluid concentrations of cholesterol, triglycerides and phospholipids, were compared with ascitic fluid total protein in 40 patients with chronic liver disease, 51patients with various neoplasms and 1 patient with cardiac failure. Seven patients withboth chronic liver disease and malignancy were considered separately. The first 54 patients (23 cirrhotic and 31 with malignancy) were used to determine median values and ranges and to define the most suitable cutoff concentrations between both groups. Median values for cholesterol (75 mg per dl), phospholipids (0.79 mmole per liter), triglycerides (75 mg per dl) and protein (3.8 gm per dl)were higher in malignant ascites compared to ascitic fluid concentrations of cholesterol (20 mg per dl), phospholipids (0.33 mmole per liter), triglycerides (51 mg per dl) and protein (1.9 gm per dl) in patients withcirrhosis. The best discrimination values were 48 mg per dl for cholesterol, 0.6 mmole per liter for phospholipids, 65 mg per dl for triglycerides and 2.5 gm per dl for protein. Application of these cutoff points to 38 subsequent patients (17 cirrhotic, 1 with cardiac failure and 20 with malignancy) revealed an efficiency of 86.8% for cholesterol, 86.8% for phospholipids, 68.4% for triglycerides and 79.0% for protein. From the data of all 92 patients, an efficiency of 92.3% forcholesterol, 79.4% for phospholipids, 72.8% for triglycerides and 79.4% for protein was calculated. We conclude that ascitic fluid cholesterol determination offers an excellent, cost-effective discrimination of ascites due to cirrhosis vs. ascites caused by malignancies

“Remarkable Influence”: The Unexpected Importance of Justice Scalia’s Deceptively Unanimous and Contested Majority Opinions

What constitutes judicial influence and how should it be measured? Curious about the broader role that rhetoric plays in judicial influence over time, we undertook a rhetorical-computational analysis of the 282 majority opinions that Justice Scalia wrote during his 30 years on the Supreme Court. Our analysis is the first to examine the full majority opinion output of a Supreme Court justice using a unique “medium data” approach that combines rhetorical coding with quantitative analysis relying on Shepard’s Citations and LexisNexis headnotes. The resulting study casts doubt on the ability of judicial authors, including Justice Scalia, to control the extent of their influence on later courts.One important finding from our study is that relying on only the vote counts of the Justices obscures the actual failures of unanimity that may generate long-lasting uncertainty. When there are concurring opinions in decisions whose vote counts are unanimous—opinions we reclassified as “deceptively unanimous”—later courts may continue to debate one or more issues over a long period of time, and that may result in a “long tail” of more frequent citations, not because of the majority opinion’s influence but because of the continuing conversation. If later courts diverge about the meaning or application of the rules established in the majority opinion, they may rely on a concurring opinion that gains or loses adherents over time. In these circumstances, both the original majority opinion and the concurring opinion will continue to be cited. And more frequent citations—to both the majority and the concurrence or concurrences—will extend long after the debate is settled as still-later cases recount the history of the dispute.A second finding emerging from our analysis is that Justice Scalia’s rhetorical statements appearedto be more or less attractive to later courts depending on the particular rhetorical context of the later judicial author. Although this finding may seem obvious, our analysis provided specific details. The federal courts of appeals, for example, were more likely to “cite” than to “follow” Justice Scalia’s precedential rules. Perhaps reflecting both their institutional role and their greater resources, the federal courts of appeals tended to more extensively discuss both the arguments made and the rules established in Justice Scalia’s majority opinions while the federal district courts and the state courts were somewhat more likely to simply follow the rules.Finally, our analysis illuminates how difficult and complex it is to discern and describe the effects of rhetorical structures, argument frames, and word choices on judicial decisionmaking and opinion writing. For example, we suspect that Justice Scalia’s stated preferences for constructing particular kinds of rhetorical rule statements—bright lines, broad categories, strict limits—may in fact have resulted in more frequent citations, which some observers might translate into an inference of greater influence. Our analysis, however, indicates that these more frequent citations over time often were the result of Scalia rule statements that either created or contributed to lingering disputes
