Cartographic mapping study

The errors associated with planimetric mapping of the United States using satellite remote sensing techniques are analyzed. Assumptions concerning the state of the art achievable for satellite mapping systems and platforms in the 1995 time frame are made. An analysis of these performance parameters is made using an interactive cartographic satellite computer model, after first validating the model using LANDSAT 1 through 3 performance parameters. An investigation of current large scale (1:24,000) US National mapping techniques is made. Using the results of this investigation, and current national mapping accuracy standards, the 1995 satellite mapping system is evaluated for its ability to meet US mapping standards for planimetric and topographic mapping at scales of 1:24,000 and smaller

Utilization of the Critical Care Mobility Guideline in the Medical Intensive Care Unit

Utilization of the Critical Care Mobility Guideline in the Medical Intensive Care Unit Michele L. Dye, MS, RN, CCRN, CCNS, ANP-BC Introduction: The Critical Care Mobility Guideline was implemented in the medical intensive care units (MICU) in a large Midwestern medical center in June 2008. Objective: To determine if MICU patients are received mobility interventions as directed by the Critical Care Mobility Guideline on days 3, 5, & 7 of their stay. Design: A quantitative descriptive research design using retrospective medical record review was used to examine the utilization of mobility measures as recommended in the Mobility Guideline. Sample: All MICU patients (n=207 on day 3) during September-November 2010 and who met inclusion criteria. Outcome measurement: The number of patients who received at least one mobility intervention on days 3, 5, & 7. Other data collected included: type of mobility intervention; time of day of the mobility intervention; SAPS II score, BMI. Conclusions: The number of patients who received mobility interventions varied and increased as the medical ICU length of stay increased. The percentage of eligible patients on day 3 who received mobility was 29.75%, and increased to 43.5% on day 7. The most common mobility intervention was out of bed to the bedside chair in the morning. Most common exclusion criterion was hemodynamic instability. The SAPS II score showed negative, non-significant correlation to mobility interventions. The utilization of the mobility guideline in MICU patients is not widespread with less than 50% of the patients without exclusion criteria received mobility interventions. Factors such as day of ICU stay, BMI did not affect whether or not a patient received mobility.A three-year embargo was granted for this item

Children's computation of complex linguistic forms: a study of frequency and imageability effects.

This study investigates the storage vs. composition of inflected forms in typically-developing children. Children aged 8-12 were tested on the production of regular and irregular past-tense forms. Storage (vs. composition) was examined by probing for past-tense frequency effects and imageability effects--both of which are diagnostic tests for storage--while controlling for a number of confounding factors. We also examined sex as a factor. Irregular inflected forms, which must depend on stored representations, always showed evidence of storage (frequency and/or imageability effects), not only across all children, but also separately in both sexes. In contrast, for regular forms, which could be either stored or composed, only girls showed evidence of storage. This pattern is similar to that found in previously-acquired adult data from the same task, with the notable exception that development affects which factors influence the storage of regulars in females: imageability plays a larger role in girls, and frequency in women. Overall, the results suggest that irregular inflected forms are always stored (in children and adults, and in both sexes), whereas regulars can be either composed or stored, with their storage a function of various item- and subject-level factors

The Effects of Magnesium Supplementation on Subjective Anxiety and Stress—A Systematic Review

Background: Anxiety related conditions are the most common affective disorders present in the general population with a lifetime prevalence of over 15%. Magnesium (Mg) status is associated with subjective anxiety, leading to the proposition that Mg supplementation may attenuate anxiety symptoms. This systematic review examines the available evidence for the efficacy of Mg supplementation in the alleviation of subjective measures of anxiety and stress. Methods: A systematic search of interventions with Mg alone or in combination (up to 5 additional ingredients) was performed in May 2016. Ovid Medline, PsychInfo, Embase, CINAHL and Cochrane databases were searched using equivalent search terms. A grey literature review of relevant sources was also undertaken. Results: 18 studies were included in the review. All reviewed studies recruited samples based upon an existing vulnerability to anxiety: mildly anxious, premenstrual syndrome (PMS), postpartum status, and hypertension. Four/eight studies in anxious samples, four/seven studies in PMS samples, and one/two studies in hypertensive samples reported positive effects of Mg on subjective anxiety outcomes. Mg had no effect on postpartum anxiety. No study administered a validated measure of subjective stress as an outcome. Conclusions: Existing evidence is suggestive of a beneficial effect of Mg on subjective anxiety in anxiety vulnerable samples. However, the quality of the existing evidence is poor. Well-designed randomised controlled trials are required to further confirm the efficacy of Mg supplementation. View Full-Tex

Corn Silage Diets for Finishing Cattle When Supplemented With Soybean Meal or Urea and DES Fed at 10 mg., 20 mg. Daily or Implanted

Corn silage properly supplemented with protein, minerals and vitamin A forms a simple and efficient diet for growing and finishing cattle. Rate of gain will be less than for high-concentrate diets, especially during late stages of finishing. However, gain per acre of corn will be greater when fed as silage than as grain

Cassiopeia A: dust factory revealed via submillimetre polarimetry

If Type-II supernovae - the evolutionary end points of short-lived, massive stars - produce a significant quantity of dust (>0.1 M_sun) then they can explain the rest-frame far-infrared emission seen in galaxies and quasars in the first Gyr of the Universe. Submillimetre observations of the Galactic supernova remnant, Cas A, provided the first observational evidence for the formation of significant quantities of dust in Type-II supernovae. In this paper we present new data which show that the submm emission from Cas A is polarised at a level significantly higher than that of its synchrotron emission. The orientation is consistent with that of the magnetic field in Cas A, implying that the polarised submm emission is associated with the remnant. No known mechanism would vary the synchrotron polarisation in this way and so we attribute the excess polarised submm flux to cold dust within the remnant, providing fresh evidence that cosmic dust can form rapidly. This is supported by the presence of both polarised and unpolarised dust emission in the north of the remnant, where there is no contamination from foreground molecular clouds. The inferred dust polarisation fraction is unprecedented (f_pol ~ 30%) which, coupled with the brief timescale available for grain alignment (<300 yr), suggests that supernova dust differs from that seen in other Galactic sources (where f_pol=2-7%), or that a highly efficient grain alignment process must operate in the environment of a supernova remnant.Comment: In press at MNRAS, 10 pages, print in colou
