Analysis of the Correlation between the Level of Contact Degradation and the Dynamic Resistance Curve in Circuit Breakers

: The DRM (dynamic contact resistance measurement) in high voltage circuit breakers is a manner of evaluating the internal ageing condition of the chamber. DRM is similar to static contact resistance measurement testing, but instead of measuring a single value when the breaker contacts are closed (static value), the ohmic resistance is measured at various contact positions, from the beginning of the contact opening until a complete separation of the contacts. The relationship between the contact resistances of the new circuit breaker and the ageing circuit breaker in operation provides subsidy for the evaluation of both the main and arcing contact conditions. This research aims to analyze the correlation between the various levels of degradation of the contacts and the configuration of the DRM curve. This work considers curve samples from new breaker chamber contacts and different levels of degradation by acceleration tests.
Optimal propulsion system design for a micro quad rotor

Title of Thesis: OPTIMAL PROPULSION SYSTEM DESIGN FOR A MICRO QUAD ROTOR Aaron M. Harrington, Masters of Science 2011 Thesis directed by: Professor Inderjit Chopra Department of Aerospace Engineering Currently a 50 gram micro quad rotor vehicle is being developed in collaboration with Daedalus Flight Systems. Optimization of the design at this scale requires a systematic study to be carried out to investigate the factors that affect the vehicles performance. Endurance of hovering vehicles at this scale is severely limited by the low efficiencies of their propulsion systems and rotor design and optimization has been performed in the past in an attempt to increase endurance, but proper coupling of the rotor with the motor has been lacking. The current study chose to investigate the factors that had the greatest effect on the vehicle's endurance through analysis of the propulsion system. Therefore, a coupled aerodynamic and structural analysis was carried out that incorporated low Reynolds number airfoil table lookup in order to predict micro rotor performance. A parametric study on rotor design was performed further determine the effect of different rotor designs on hover performance. The experiments performed showed that airfoil camber had the biggest impact on rotor efficiency and other factors such as leading edge shape, number of blades, max camber location, and blade planform taper only had negligible influence on performance. Systematic studies of the interactions between micro rotor blades operating in close proximity to each other were performed in order to determine the changes in rotor efficiency that might occur in a compact quad rotor design. Tests done on the effect of rotor separation demonstrated that there is a negligible interaction between rotors operating near each other. Brushless motors were also tested systematically and characterized by their torque, rpm, and efficiency. It was found that the maximum efficiency of the motors tested was only 60%, which has significant effects on the efficiency of the coupled system. A method for rotor and motor coupling was also established that utilized the motor efficiency curves and the known torque and rotational speed of the rotors at their operating thrust. Through this, it was found that propulsion system efficiency could be increased by 10% by simply using the proper motor and rotor combination. Further, coupled design would have additional benefits and could increase vehicle efficiency further. OPTIMAL PROPULSION SYSTEM DESIGN FOR A MICRO QUAD ROTOR
Accessibility and Auto Use in a Motorized Metropolis

This study uses data from the South Coast metropolitan area in Southern California to examine the effects of automobile and transit accessibility on vehicle holding, vehicle type choice and vehicle use. Household-based models are developed for the total number of vehicles available to the household, the number of vehicles per household member and per driver in the household, the choice of vehicle type for the most recently acquired vehicle and its use in terms of annual mileage. In each model, indicators of accessibility by auto and that by transit are introduced along with residential density and other indicators of residence area, and household attributes. The objective is to use statistical analysis of survey data to assess whether transit accessibility affects auto ownership, vehicle type choice or use in an automobile-dominated area.
Incidence and clinical profiles of COVID-19 in patients with gynecological surgery: A single center descriptive study from Spain.

Background: The inflammatory reaction after a surgical intervention could exacerbate the course of the COVID-19. We aim to determine the rate of COVID-19 and its complications among gynecological surgeries in the context of different measures taken during the pandemic period in our department. Methods: A retrospective longitudinal observational study was conducted. Clinical records of patients who underwent gynecological surgery from March 1 st to April 10 th , 2020 were reviewed. During this period, three different approachs were made: first phase, without any screening or surgical restrictions; second phase, with presurgical epidemiological screening using a specific questionnaire; and third phase, also with presurgical SARS-COV-19 RT-PCR. During the second and third phases the surgical activity and complexity were restricted, and different workflows were established for patient with suspected/confirmed infection. After hospital discharge, telephone follow-up was performed and screening for COVID-19 was carried out. Complications from the disease were analyzed. Results : Of the 118 patients that underwent gynecological surgeries, 10 (8.5%) were perioperatively diagnosed with COVID-19. Of these patients, 8 (80%) were not pre-surgical screened for SARS-CoV-2 infection, neither clinical nor with RT-PCR. The other 2 (20%) were preoperative screened with RT-PCR, one of them with a positive test result. Screening false negative rate was 0.8%. No postoperative complications derived from COVID-19 were observed. Conclusions: The establishment of different surgical workflows, the reduction of surgical complexity, and the use of a pre-surgical screening to detect patient at SARS-CoV-2 infection risk, could reduce the postoperative complications derived from that infection and improve surgical outcomes.
Trace Elements Adsorption from Solutions and Acid Mine Drainage Using Agricultural By-products

ABSTRACT To mitigate the trace elements (TE) dispersion in acid mine drainage (AMD), laboratory experiments were carried out comparing nine agricultural by-products. Five adsorbent materials were selected for adsorption batch experiments. Then, the biosorbents were tested to remove TE from AMD collected from oxidized tailings heaps, using equilibrium experiments. The As adsorption on carbonatite was high (15.4 g kg−1); Cd (4.1 g kg−1) on cow manure; Cu (17.9 g kg−1) on carbonatite; Pb (14.1 g kg−1), and Zn (16.4 g kg−1) on rabbit manure. The Zn adsorption on oat straw and carbonatite was well fit by Freundlich isotherm. The Langmuir equation mimics well Zn and Cd adsorption by peat moss and caw manure; Cu adsorption on peat moss and vermicompost. Except for vermicompost and carbonatite, the adsorption improved as the buffer capacity of the biosorbents increased, following a second-order equation. The FTIR analysis showed that the carboxylic, aromatic, and aliphatic aldehyde groups were involved in TE adsorption. Soluble-As, -Cd, -Cu, and -Zn from AMD were removed (90%) by the addition of 4 and 8% (m/v) of sheep manure, cow manure, rabbit manure, vermicompost, and carbonatite. Lead concentration in AMD was increased due to the addition of the biosorbents.
Study of Fingerprints in Relation to Dental Caries

Fingerprints of 40 individuals of age group 4-18 years were sampled from Agyaram Kherbari L.P. School, D. L. P School and J.N. M. E school (Dhubri District) to study the pattern of fingerprints and their relation with dental caries as they may be associated with the disease and serve as a predictor for early detection of it. Analysis was carried out in the affected individuals and it was found that the per centage of ulnar loop is highest (23.75%) in females and also in males (19.7%) and per centage of lateral loop is lowest (1.25% and 1.24%), whereas the control had more per centage of ulnar loop in both males and females. The study shows an association of dermatoglyphic pattern of fingerprints and prevalence of dental caries.
Gray matter abnormalities in pediatric focal and generalized epilepsy: A voxel-based morphometry study with MRI at 3.0 T

Background : Our aims were to explore gray matter volume (GMV) abnormalities in focal and generalized epilepsy children compared to healthy group using a voxel-based morphometry (VBM) methodology, and to determine whether the regions of any observed structural changes are correlated with clinical characteristics. Methods: Thirty-two epilepsy children ( 18 with focal epilepsy, 14 with generalized epilepsy) and 18 control subjects were recruited. All participants were imaged structural MRI scans with a 3.0 T MR system. VBM analysis using statistical parametric mapping 8 (SPM8) was first performed to detect gray matter reduction in focal and generalized epilepsy children compared to controls. Then we analyzed the correlations between GMV changes and clinical features of epilepsy patients. Results: In the patient-control group comparison of VBM, the left hippocampus, left thalamus, left paraHippocampal and bilateral putamen exhibited a significantly GMV decreased. In stratified analysis, the focal epilepsy children showed GMV reductions in left thalamus, left hippocampus and bilateral putamen relative to controls; the GMV exhibited extensive reductions in left parahippocampal, left putamen, and right supplementary motor area in generalized epilepsy children compared to controls. No significant difference was found in regions of GMV abnormalities correlated with disease durationand age of onset in both the focal and generalized epilepsy groups. Conclusions: By performing VBM to detect GMV changes in children, our study demonstrates the GMV reductions exist in different regions in focal and generalized epilepsy patients. Our study further provides structural neuroimaging evidence on the pathophysiology of focal and generalized epilepsy children.
Nucleotide sequencing of specific genes in nuclear and plastid genomes of good performance hybrids derived from interspecific hybridization in the genus Jatropha

Biodiesel, produced from plant oil, has emerged as an attractive renewable energy source. Physic nut ( Jatropha curcas L.) has gained widespread attention from both biodiesel producers and the research community due to its advantages of high biodiesel production, rapid growth, tolerance and convenient propagation. The current study used interspecific hybridization between J. curcas and Jatropha species and good performance hybrids DNA to study the relationship. Standardized DNA in the organism was used for DNA sequencing of the good performance hybrids as well as other Jatropha species. Sequencing was performed at four gene regions of the rbc L and trn H– psb A intergenic spacers in the plastid genome and the internal transcribed spacer of rDNA and stearoyl-acyl carrier protein desaturase ( SAD ) in the nuclear genome. Alignment of the SAD gene sequence showed high polymorphism among the five Jatropha species and hybrids. Phylogenetic trees based on the nucleotide sequences of regions could show that J. integerrima was closely related to J. curcas better than either gene .

Power controlled microwave reactor for the removal of NOx and SOx from the exhaust of marine diesel engine

Microwave energy in combination with AC corona initiated non-thermal plasma is a promising method for removing of NOx and SOx from the exhaust of diesel engine. Recently experimental work shows that a microwave oven (1.8 kW) can be used as an experimental system to research this subject. However, microwave ovens are often based on cyclic mode operation for controlling the power. This type of control is not suitable for the purpose of continuously cleaning the exhaust gas. This study investigates the use of phase control circuit as a regulator for controlling the power in the microwave reactor. The system was tested and its performance was evaluated. It was observed that phase-controlled power regulator could be successfully used for quasi-continuous (fast-switching) power regulation with the maximization of power efficiency. The developed system is used to reduce the emission gases from a marine diesel engine. Different power settings were used to investigate the effect of the power on the reduction efficiency. The same controlled microwave source based non-thermal plasma reactor will be used to investigate the pollutant removal efficiency of the exhaust gas emitted from a 40 kW marine Diesel engine.

Testing in support of on-site storage of residues in the Pipe Overpack Container

The disposition of the large back-log of plutonium residues at the Rocky Flats Environmental Technology Site (Rocky Flats) will require interim storage and subsequent shipment to a waste repository. Current plans call for disposal at the Waste Isolation Pilot Plant (WIPP) and the transportation to WIPP in the TRUPACT-II. The transportation phase will require the residues to be packaged in a container that is more robust than a standard 55-gallon waste drum. Rocky Flats has designed the Pipe Overpack Container to meet this need. It is desirable to use this same waste packaging for interim on-site storage in non-hardened buildings. To meet the safety concerns for this storage the Pipe Overpack Container has been subjected to a series of tests at Sandia National Laboratories in Albuquerque, New Mexico. In addition to the tests required to qualify the Pipe Overpack Container as a waste container for shipment in the TRUPACT-II several tests were performed solely for the purpose of qualifying the container for interim storage. This report will describe these tests and the packages response to the tests. 12 figs., 3 tabs.
Accounting for Dispersion Effects in DFT Framework of Electrocatalysis: A Case Study of Solvent Mediated Oxygen Reduction Reaction

Density functional theory (DFT) is a pivotal tool in the field of computational electrocatalysis. Dispersion effects, which are not incorporated in the regular DFT framework, play a significant role in improving the accuracy of DFT-based catalytic simulations. We perform a calibration study for addressing the effect of different dispersion corrected DFT methods in determining the electrocatalytic properties by conducting a case study of oxygen reduction reaction (ORR). The distinct trends of these methods towards determining the structural, energetic, and electronic properties of catalysis are scrutinized. By systematically incorporating an upgraded solvation model, the importance of the inclusion of dispersion effects for the accurate prediction of chemical and physical properties governing the catalytic activity is illustrated. The combined thermodynamic and kinetic analysis predicts a uniform ORR activity trend, with semi-empirical dispersion corrected DFT methods emerging as optimal choices with comparable or higher accuracy than advanced van der Waal’s methods.
Impeding And Facilitating Factors In The Implementation Of Lean Enterprise Methodology

Leonard, Brian Scott, M.S., Purdue University, December 2007. Impeding and Facilitating Factors in the Implementation of Lean Enterprise Methodology. Major Advisors: Rodney Vandeveer and Linda Naimi. The field of lean enterprise has continued to grow since being introduced by the Toyota Corporation after World War II. In academia lean strategies are being introduced in order to prepare students for this new era in operating procedures. Currently, the majority of research in business and academia is focused on processes and methodology, but leadership strategies are yet to be fully examined. According to Hamilton (2006) there are insufficient resources and research that contribute to understanding successful implementation strategies. Hamilton (2006) expresses concern of the lack of focus on leadership strategies and employee development in lean enterprise. This qualitative study explores factors that impede and facilitate implementation of lean processes in business and industry. Business leaders whose organizations are implementing lean processes were interviewed. Furthermore, interviews were conducted with consultants in the field of lean enterprise. Other data was collected from document review, site visits, and observations, where feasible. Grounded theory and open coding techniques were used to sort the data according to major categories and themes. Factors were then subjected to specific statistical tests to determine the degree of relationship
Efficiency wages, public service motivation and effort in Malaysia: An empirical case study of Universiti Sains Malaysia

Until now, the bulk of the studies conducted on the relationships between efficiency wages, public service motivation (PSM), and effort focused exclusively on developed and advanced countries. Very little has been written about these relationships on developing countries. Finding additional knowledge on the experiences of the developing countries would not only be helpful in improving the efficiency of public employees in developing countries, but would also help to enrich and expand this field of knowledge. Perhaps of more importance is that this study were provides some rare glimpses into the dynamics of the relationship between public sector employers and employees in achieving their prescribed outcomes from a developing world perspective. Malaysia is taken as a case study to explore and highlight some common problems shared by many developing countries in improving the efficiency of their public employees. As far as the author could judge (after an extensive review of the literature), this is the first attempt to analyse the relationships between efficiency wages, PSM, and effort on Malaysia. The relationships between efficiency wage, PSM, and effort were analysed and tested on the Malaysian public sector using Universiti Sains Malaysia (USM) as a case study. This study found employees’ effort levels in USM during the survey period were driven more so by PSM rather than by efficiency wages. This study also highlighted a few policy recommendations based on findings of this study.
Exponential Manipulative Chips In Learning Integral Exponentt

This study attempted to determine the student’s performance level in learning integral exponent of grade 8 students. The descriptive research method was used in this study where a total population of 70 respondents was obtained using cluster random sampling. The research instrument was validated and tested using Cronbach’s Alpha. The descriptive analysis, mean, and paired t-test were utilized for statistical analysis. The main purpose of the study was to determine if there is a significant difference between the student’s performance in the pre-test and post-test assessment in learning integral exponents with the aid of exponential manipulative chips. The mean and paired t-test was used as the statistical treatment to determine if there is a significant difference in their performance in the pre-test and post-test. The gathered data undergo statistical analysis with the use of appropriate statistical tools and arrived with result that there is a significant difference between the student’s performance in learning integral exponent in the pre-test and post-test, with a pvalue of 0.007 less than the 0.05 alpha. Students also find the use of manipulatives very useful having an overall rating mean on their perception of 4.4 interpreted as very useful, thus an exponential manipulative chip is an effective instructional tool in learning integral exponents.
