The Use of Bifocal Soft Contact Lenses in the Fort Rucker Aviation Environment.

Abstract : There are problems with the compatibility of spectacles and certain helmet mounted electro-optical visual display systems. The incompatibility has been partially resolved with single vision contact lenses. However, these contact lenses have not helped senior aviators, who must wear bifocal glasses due to their presbyopia. The purpose of this study was to compare the performance of bifocal soft contact lenses with that of bifocal spectacle lenses to determine if contact lenses are an option for helping older aviators meet the visual requirements needed to fly military aircraft. Seventeen volunteer presbyopic aviators from Fort Rucker were fitted with five bifocal soft contact lens combinations and bifocal glasses. A four-phase investigation was conducted: a clinical phase involving the fitting of the bifocal contact lenses; a laboratory phase involving measurements of visual functions; a simulator phase involving measures of visual performance in simulated flight conditions; and an operational phase consisting of subjective responses regarding in-flight use of bifocal contact lenses. In general, vision in the best performing bifocal contact lenses typically was slightly reduced from vision in bifocal spectacles. The amount of the reduction, and whether it was clinically significant, depended on the refractive error of the subject (myopes generally performed better), the add group of the subject (low add group subjects performed better), and the type of bifocal contact lens. Aviators performed flight simulation maneuvers better in bifocal contact lenses than in bifocal glasses, and they evaluated their own ease of vision while performing aviation duties to be much easier in bifocal contact lenses than in bifocal glasses. In actual flight operations, each aviator preferred bifocal contact lenses over bifocal spectacles. Bifocal soft contact lenses are an acceptable
The Marketing System of Exchange Between Regulatory and Political Entrepreneurs Engaging in Arbitrage

After receiving cease and desist letters in 2018, Bird strategically developed hospitable relationships with politicians that allowed the scooter-sharing firm to continue operating. Bird acts as a regulatory entrepreneur in seeking unfair legal treatment and the politicians brokering the legal deal as political entrepreneurs. The business models for unfairly changing or applying law represents entrepreneurial arbitrage. A mixed methods approach examines the structure of relationships between regulatory and political entrepreneurs through the Bootleggers and Baptists conceptual lens. Like Bird solving traffic and pollution problems for city leaders, Baptists served as a moral cover for illegal liquor vendors. Guided by a general systems theory, it is found that the micro-level, relational exchanges both assign value to as well as uses intellectual commodities to establish expectations guiding ongoing exchanges. Therefore, a marketing system is uncovered. This research also finds relationships structured by favors in sharp contrast to political markets governed by threats.

NON-LINEAR DYNAMIC ANALYSIS OF CONCRETE PAVEMENTS

The conventional analysis method for rigid pavement is usually based on a closed-form solution for an infinitely long pavement subjected to static loads. The fact that rigid pavements have finite slab dimensions and are subjected to moving loads make the predicted pavement response under the closed-form assumptions inappropriate. Finite element methods (FEM) can be better used to model concrete pavements. Even though a number of studies of concrete pavements have been conducted using FEM, most of these assume that the concrete slab is a thin or thick plate resting on a Winkler dense liquid or elastic solid foundation. Static loading conditions are also assumed. This paper describes a study conducted at Purdue University that evaluated the damage effect of overloaded trucks on the Indiana highway network. A 3D dynamic FEM (3D-DFEM) was used to analyze both asphalt and concrete pavements. The concrete pavement was modeled as 3-D slabs resting on a layered foundation. The linear and non-linear material properties of the different layers--concrete slab, subbase, and subgrade--were represented. Truck loads moving at varying speeds were applied, and the pavement elastic and plastic responses were predicted. The pavement static response predicted by the 3D-DFEM was compared with that predicted using Westergaard's equations for similar conditions and no significant difference was found. A comparison was also made between the 3D-DFEM predictions and actual pavement deflections measured under moving trucks. The predicted pavement deflections were found to agree with the measured deflections. These static and dynamic verification studies demonstrate that the 3D-DFEM can be confidently used to predict actual pavement response from moving loads.
The pros and cons of long distance commuting: Comments from South Australian mining and resource workers

Long Distance Commuting (LDC), also referred to as fly-in-fly-out (FIFO), involves a cycle of working for extended periods away from the family home. The experiences of LDC workers were examined through a study of 104 minerals and resources industry workers and partners in South Australia. SA workers comment that LDC is satisfying and has positive personal, lifestyle, career and family benefits. Stressors include shift work, long rosters, separation from friends and family, missing family events, isolation, and fatigue. Feelings of anxiety or reports of depression which commonly feature in other literature were not a feature of this study. Short rosters, a high standard on-site services and amenities coupled with training and career opportunities, local management and peer support, a family friendly organisational culture and regular communication with family, are key factors contributing to sustainability of this workforce model.
High Level Waste Demonstration of the Caustic-Side Solvent Extraction Process with Optimized Solvent in the 2-CM Centrifugal Contactor Apparatus Using Tank 37H/44F Supernate

This report summarizes the results of tests at Savannah River Technology Center with radioactively spiked simulated Tank 37H/44F waste and actual Tank 37H/44F supernate composite waste. The spiked simulant tests demonstrated that stable hydraulic conditions could be maintained with the new solvent formulation and the radioactive feed could be decontaminated to background levels. The 24 hour actual Tank 37H/44F waste test demonstrated similar hydraulic stability and higher decontamination factors.
Factors Influencing the Severity of Damage in Bus Accidents in 2002 in Turkey: An Application of Ordered Response Models

This paper presents the use of ordered logit and probit models to bring light on the most significance factors that considerably change the severity of vehicle damages in bus accidents in 2002 in Turkey. Data recorded by The Department of Traffic Training and Research of General Directorate of Security Affairs of Turkey is used in this study and the severity of damages is classified according to four levels: no damage, little damage, damage of middling quality and high damage. With reference to the ordinality of the dependent variable determined as the severity of vehicle damages in bus accidents, the commonly used estimation techniques known as ordered response models are chosen to reveal the major risk factors.The results suggest that, all variables indicating the place of the accident, having an accident at night and all weather conditions increase the severity of damages. Traveling in the same direction in two-vehicle accidents occurring as bumping from one side of another vehicle, accidents occurring other than bumping rear-end, from one side, to a stationary material, to a stable vehicle and rollover, and high school-graduated drivers lead to low damages.
ACIDIFICATION OF PHYTASE TREATED DIET IMPROVES THE BODY COMPOSITION AND BONE MINERALIZATION OF JUVENILE ROHU (Labeo rohita)

A 3×3 factorial feeding experimental was performed to find out the role of citric acid and phytase supplementations and interaction in improving body chemical composition and bone mineralization by adding them in plant based diet of rohu (Labeo rohita) juveniles. At first, the basal diet having citric acid at three different levels was supplemented i.e. 0%, 1.5% and 3%, and then three different phytase levels (0 FTU kgˉ1, 750 FTU kgˉ1 and 1000 FTU kgˉ1) were supplemented further with each level of citric acid. Hence, total 9 experimental diets were formulated in this feeding trial. The results revealed that the concentration of total ash, crude protein and dry matter content significantly increased (p≤0.05), when treated with citric acid and phytase. However, contents of crude fat showed a reduced level in the carcass of juveniles by feeding both additives. The supplementation of citric acid and phytase both significantly (p≤0.05) affected the bone mineralization of fish. An increasing trend was observed for the body proximate analysis and bone mineral concentrations with an increase of supplements level in the diet. Conclusively, the results of this experiment showed that the supplementation of citric acid and phytase in the diet of L. rohita improved body composition and bone mineralization.
OVERREPORTING AND MEASURED EFFECTIVENESS OF SEAT BELTS IN MOTOR VEHICLE CRASHES IN UTAH

Motor vehicle crashes are a leading cause of injury and mortality in the United States. The effectiveness of seat belt use has been difficult to study because of the unavailability of population-based crash data bases that include all noninjured occupants. The 1991 Utah Crash Outcome Data Evaluation System data base was developed to determine seat belt effectiveness. It includes occupants of all police-reported motor vehicle crashes. Seat belt effectiveness may be overestimated, however, because of self-reporting of seat belt use when crash occupants are questioned by police. The effect of misclassification of seat belt use on the calculated odds ratio associated with seat belt use was studied by using logistic regression models of four levels of injury. The odds ratio associated with seat belt use for any degree of injury was 0.448 [95% confidence interval (CI) 0.425-0.473]; the odds ratios associated with seat belt use for injuries requiring outpatient emergency care, hospitalization, or fatalities were 0.476 (95% CI 0.449-0.504), 0.203 (95% CI 0.170-0.241), and 0.148 (95% CI 0.097-0.226), respectively. Adjustment of the fraction of correct classification of seat belt use among reported belt users decreased the protective effect associated with seat belt use for all four levels of injury. This is consistent with overestimation of seat belt effectiveness associated with nondifferential misclassification. Based on the assumption that the 1991 observational use rate applies to the 1991 crash population, odds ratios were corrected for seat belt self reporting bias. The corrected odds ratio associated with protection from any degree of injury was 0.723 (95% CI 0.685-0.763); the corrected odds ratios associated with seat belt use and injuries requiring outpatient emergency care, hospitalization, or fatalities were 0.747 (95% CI 0.705-0.791), 0.505 (95% CI 0.421-0.606), and 0.455 (95% CI 0.296-0.697), respectively. The study results confirm the protective effect of seat belts in motor vehicle crashes and provide a methodology for correcting seat belt effectiveness estimates.
Preparation and Evaluation of Hydrogel Nanoparticles as Drug Delivery System

Hydrogel nanoparticles (NPs) can be used for colon drug delivery, utilizing Methotrexate (MTX) as a model drug. MTX loaded hydrogel NPs were prepared using Poly-acrylamide-grafted- gum ghatti (PAAm-g-Gg), which is pH sensitive. PAAm-g-Gg was synthesized by free radical polymerization. MTX loaded hydrogel NPs was prepared from PAAm-g-Gg by using nanoemulsification polymer crosslinking method. FT-IR and DSC studies of the prepared NPs indicated no chemical change of MTX in the hydrogel NPs. The prepared hydrogel NPs showed mean diameters in the range of 238 ± 0.57 nm to 1064 ± 0.99 nm. The encapsulation efficiency of the drug was found to be 39.11% to 48.84%. The suitability of the polyacrylamide grafted gum ghatti hydrogel NPs for the release of Methotrexate was studied by in vitro release at pH 1.2 and 7.4. It was observed that, there was no significant amount of drug release in gastric pH and 97.28% of drug release at pH 7.4 for formulation F6 at the end of 12 hrs. Based on result formulation F6 was considered as the best formulation and further evaluated for stability studies and characterized for surface morphology using SEM. SEM photographs have shown that the hydrogel NPs are spherical in shape and the stability study data indicated no significant change in the drug content.

Investigations into the effects of secondary-frequency additions on slender rotating structures

Title of Document: INVESTIGATIONS INTO THE EFFECTS OF SECONDARY-FREQUENCY ADDITIONS ON SLENDER ROTATING STRUCTURES Gregory William Meyer, Master of Science, 2014 Directed By: Professor Balakumar Balachandran Department of Mechanical Engineering Drill strings are slender structures used extensively in drilling and mining operations. In this thesis work, secondary-frequency input additions to the drive speed input are considered and the resulting influence on system dynamics is examined. Experimental studies are conducted with a laboratory scale drill-string arrangement, and high-frequency and low-frequency additions are considered for cases in which the drive speed frequency is close to either a bending mode or torsion mode natural frequency. It is found that carefully chosen secondary-frequency additions can be used to attenuate undesirable system dynamics, especially, for rotary systems. To complement the experiments, numerical studies are conducted with a reduced-order model of the drill-string system. The obtained numerical results are found to be in reasonable agreement with the experimental results. Preliminary numerical results obtained in the presence of rotor-stator interactions are also included. In addition, areas in which the model construction will need further development are also discussed. The findings of this work can be useful for considering secondary-frequency addition based schemes for controlling bending and torsional motions of drill-string systems.
The use of virtual reality in studying prejudice and its reduction: A systematic review

This systematic review provides an up-to-date analysis of existing literature about Virtual Reality (VR) and prejudice. How has VR been used in studying intergroup attitudes, bias and prejudice, are VR interventions effective at reducing prejudice, and what methodological advantages and limitations does VR provide compared to traditional methods are the questions we aim to answer. The included studies had to use VR to create an interaction with one or more avatars belonging to an outgroup, and/or embodiment in an outgroup member; furthermore, they had to be quantitative and peer-reviewed. The review of the 64 included studies shows the potential of VR contact to improve intergroup relations. Nevertheless, the results suggest that under certain circumstances VR contact can increase prejudice as well. We discuss these results in relation to the intergroup perspective (i.e., minority or majority) and target minority groups used in the studies. An analysis of potential mediators and moderators is also carried out. We then identify and address the most pressing theoretical and methodological issues concerning VR as a method to reduce prejudice.
Advanced fibre circuitry for all-optical signal processing

This thesis presents results of new types of fibre lasers and oscillators as well as a new all-fibre nonlinear modulator with nearly instantaneous response time. The development of a simple and stable, passively mode-locked source of picosecond pulses is described in chapter 2. Here the mode locking of the laser was obtained by using the combined effect of frequency-shifted feedback and a nonlinear amplifying loop mirror. The new cavity configuration allowed tuning of the laser continuously over 25 nm of the erbium gain bandwidth by using a bulk diffraction grating. The shortest reported pulse width (1.2 ps) from this type of laser has been demonstrated. A complete characterisation of the laser, including its mode locking build-up time, is presented. Cascaded nonlinearity in quadratic nonlinear materials is the basis in realising nonlinearity free optical amplifiers. Experimental results on cascaded nonlinearity in a periodically poled lithium niobate sample are presented in chapter 3. A nonlinear phase shift of more than 1.5p was obtained from only a 4 mm long sample due to its large effective nonlinear refractive index coefficient (~1 x 10-13 cm2/W). Experiments on the nonlinear phase shift compensation in an optical fibre and amplifier are presented in chapter 4. Phase shift compensation of more than 1.5p has been successfully demonstrated. Chapter 5 presents theoretical investigations on the modulation of optical signals using the stimulated Raman scattering (SRS) process in silica fibre. Numerical results reveal that to modulate signals in this scheme it is necessary to consider other competing nonlinear effects such as cascaded SRS, modulation instability etc. actively. Signal modulation as fast as 250 - 300 GHz can be realised using this intensity modulator. Chapter 6 describes the experimental results on the modulation of optical signal using SRS in optical fibre. With this Raman intensity modulator, bit-by-bit modulation of 10 Gbit/s simulated data stream has been demonstrated. An extinction ratio (modulation depth) of more than 15 dB was realised. The proposed intensity modulator can also be used as a time domain scalpel and can create a dark pulse in a bright background.
Targeted Temperature Management in Postcardiac Arrest Syndrome: A Single-Center Experience with 47 Patients

Our aim in this study is to retrospectively analyze the results of Targeted Temperature Management (TTM) treatment in our intensive care unit. Following the ethics committee's approval, the demographic data, cardiac arrest history, the follow-up process, and the final status of patients who were applied TTM in Sakarya University Training and Research Hospital Anesthesia Intensive Care Unit between January 2017 and December 2019 were recorded. Then, the effect of these parameters on mortality was evaluated using regression analysis. Data of 47 patients who met the study criteria were analyzed. The mean age of the patients was 50 ± 16 and 14 (29.8%) patients were female. The duration of cardiopulmonary resuscitation (CPR) was 22.35 ± 16.08 minutes, 35 (74.5%) patients had a witness to arrest, 25 (53.2%) patients were arrested in the hospital, and 13 (27.7%) patients had shockable rhythm. It was determined that 60% of the patients died, 20% of them were care patients with poor neurological outcomes and 20% of them were discharged outpatient with good neurological outcomes. Age, development of acute renal failure, requiring vasopressor, high APACHE scores, and length of hospital stay were found to be independent risk factors for mortality.
STUDY OF NEBULIZED FUROSEMIDE AND SALBUTAMOL IN PEDIATRIC HEART FAILURE DUE TO CONGENITAL HEART DISEASES

Background: One of the most serious complications of congenital heart diseases (CHD) is heart failure. Salbutamol is used as a front line in the treatment. Nebulized furosemide have been reported to be have good benefits of the clinical outcome. Aim of the study: This work was done to detect the value of nebulized furosemide in pediatric heart failure patients with congenital heart disease and to compare its effectiveness to nebulized salbutamol. Patients and methods: This were a randomized controlled trial included 60 patients who met the inclusion criteria and were divided into three groups: First group we used nebulized furosemide alone, second group we used nebulized salbutamol alone. The third group we used nebulized furosemide with bronchodilator salbutamol. Patients were assessed clinically, laboratory investigations including arterial blood gases, and radiologically assessed by chest x ray, echocardiography. Severity of heart failure was assessed by modified Ross classification and assessment of respiratory distress assessed by Down's score. Results: In Comparison between Furosemide group, Salbutamol group and Combination group regarding ejection fraction EF (%) and fractional shortening FS (%) for systolic function estimation, it showed significant statistically significant difference. Cases subjected to nebulized furosemide showed more improvement in EF (%) and FS (%) after one day of using nebulization than Salbutamol group and Combination group. The mean value of Heart Rate (HR) was statistically lower among Furosemide group than Salbutamol group alone, and Combination group. Among Furosemide group, the mean value of RR, HR, SBB, DBP were statistically lower among after nebulization than before. The mean value of O2 saturation (%) was statistically higher among after than before nebulization. The Mean value of RR was statistically lower among after than before nebulization. While Mean value of O2 saturation. (%) was statistically higher among after than before regarding Combination group. Conclusion: Nebulized furosemide is more effective than salbutamol in improving EF, FS relieving respiratory distress, improving oxygen saturation in heart failure cases with congenital heart defect.
