Basic MOSFET Fabrication

The MOSFET, or metal-oxide-semiconductor field-effect transistor, are the sole entities responsible for processing in microchips of everyday electronics, yet they have become extremely small. How can one manufacture such a small, powerful product? By using the simple process of pushing ions away with a nearby electric charge, a switch can be compressed down to unimaginable sizes

HI-deficient galaxies in intermediate density environments

Observations show that spiral galaxies in galaxy clusters tend to have on average less neutral hydrogen (HI) than galaxies of the same type and size in the field. There is accumulating evidence that such HI-deficient galaxies are also relatively frequent in galaxy groups. An important question is, which mechanisms are responsible for the gas deficiency in galaxy groups. To gain a better understanding of how environment affects the gas content of galaxies, we identified a sample of six HI-deficient galaxies from the HI Parkes All Sky Survey (HIPASS) using HI-optical scaling relations. One of the galaxies is located in the outskirts of the Fornax cluster, four are in loose galaxy groups and one is in a galaxy triplet. We present new high resolution HI observations with the Australia Telescope Compact Array (ATCA) of these galaxies. We discuss the possible cause of HI-deficiency in these galaxies based on HI observations and various multi-wavelength data. We find that the galaxies have truncated HI disks, lopsided gas distribution and some show asymmetries in their stellar disks. We conclude that both ram pressure stripping and tidal interactions are important gas removal mechanisms in low density environments.Comment: Accepted to MNRAS, 17 pages, 10 figures, 7 table

Practice Characteristics of Graduates of East Tennessee State University Quillen College of Medicine: Factors Related to Career Choices in Primary Care

The nation is facing a physician shortage, specifically in relation to primary care and in rural underserved areas. The most basic function of a medical school is to educate physicians to care for the national population. The purpose of this study was to examine the physician practicing characteristics of the graduates of East Tennessee State University Quillen College of Medicine including factors that influence graduates’ specialty choices and practice locations, especially those related to primary care. Secondary data for this study were collected from the college’s student database system and the American Medical Association Physician Masterfile. The study population included all living graduates with Doctor of Medicine (MD) degrees who graduated from 1998 through 2009 (n=678). Statistical procedures included Pearson Chi-square, logistic regression, independent t tests, ANOVA, and multiple linear regression. Data analyses revealed that the majority of graduates were between 24 and 29 years of age, male, white, non-Hispanic, and from metropolitan hometowns. Most had completed the generalist track and initially entered a primary care residency training program. The majority passed USMLE Step 1 and Step 2 on the first attempt. The USMLE Step 2-CK average was 212.50. The average cumulative GPA was 3.44. Graduates were nearly evenly divided between primary care and nonprimary care practice, with the majority practicing in metropolitan areas. Graduates who initially entered primary care residency training were more likely to practice primary care medicine than those who entered nonprimary care programs; however, fewer graduates were practicing primary care than had entered primary care residency training. Graduates who attended internal medicine residency training were less likely to be practicing primary care medicine than those who attended family medicine, pediatrics, or OB/GYN programs. Women and Rural Primary Care Track graduates were significantly more likely to practice primary care than were men and generalist track graduates, respectively. Nonprimary care physicians had significantly higher USMLE Step 2-CK scores than did primary care physicians (PCPs). PCPs practiced in more rural locales than non-PCPs. Family physician graduates tended to practice in more rural locales than OB/GYNs or pediatricians. Hometown location predicted practice location over and above medical school track

Gender Differences in Working Memory in Humans Tested on a Virtual Morris Water Maze.

A computerized virtual version of the Morris water maze (vMWM) was used to assess human gender differences in spatial working memory. In Experiment 1, the release point and platform location was changed on every other trial for 20 trials. Men had significantly reduced acquisition latencies and more accurate heading errors on the first daily trial compared to women. In Experiment 2, the release point and platform location was changed every fourth trial for 20 trials. Men had significantly shorter acquisition latencies and path lengths than women. Experiment 3 was identical to Experiment 2, except that environmental cues were changed throughout testing. Men had significantly shorter acquisition latencies and path lengths than did the women. These studies are the first to demonstrate significant gender differences in a spatial working memory version of the vMWM

Dynamic Characterization of DuroProtect, a Fiber-Reinforced Ballistics Composite

Dynamic characterization of materials has become increasingly common, as it is important to understand how materials behave under sudden loads. Understanding these properties can aid in material selection for novel designs. DuroProtect, a fiber-reinforced ballistics composite developed by Rӧchling, was tested for its dynamic properties at high strain-rates. The Split Hopkinson Pressure Bar (SHPB) test was used to obtain dynamic properties at high strain-rates under compressive loading conditions. Tests were initially conducted to validate force equilibriums for each sample. The data measured from the strain gages mounted on the incident and transmission bars and the elastic wave propagation theories yields the stress-strain curves. DuroProtect Level 1 and Level 2 samples were tested at strain rate ranges between ~800/s to ~1900/s and ~1300/s to ~2000/s, respectively. Differences between Level 1 and Level 2 samples were attributed by the number of fiber layers and thickness of the manufactured panels. Results showed no conclusive evidence for strain-rate sensitivity within the strain-rates tested for Level 1 or Level 2, as initially hypothesized. A comparison study between the two thicknesses revealed that Level 1 had the greatest ultimate compressive strength at a range of 547-595 MPa. Level 2, however, had the greatest specific energy of 25-44 kJ. The Level 1 and Level 2 stress-strain measurements for the DuroProtect composite were consistent with the properties expected for fiber-reinforced composites, although there is no conclusive evidence of strain-rate sensitive behaviors within the tested ranges of strain-rates

The Impact of Labor Constraints on the Farm Performance

Stricter immigration policies that affect an estimated 12 million unauthorized immigrants, 40% of whom are hired as farm workers, can potentially leave the highly labor-dependent organic farms more economically vulnerable. The displacement of unauthorized immigrants will expectedly create labor shortages. This study analyzes the impact of hiring constraints and changes in farm labor market conditions (due to stricter immigration policies) on the technical efficiency and financial performance of organic and conventional farms. A production function approach is used to analyze survey data that has a mix of organic and conventional farms in the Southeast region. Adjustment strategies to deal with labor shortage and providing workers with nonwage incentives have been determined to be an important determinant of farm income. Among the strategies, adjustment of wage and nonwage benefits were found to be the most effective but a combination of strategies is the most preferred approach to deal with labor shortage. Furthermore, we found productivity difference between farmers with labor shortage adjustment strategies and those who do not.Agricultural Finance, Production Economics, Productivity Analysis,

Linking Interactional Justice to Work-to-Family Conflict: The Mediating Role of Emotional Exhaustion

This study examined the effect of interactional justice on work– to-family conflict and whether emotional exhaustion was a mediator of this relationship. Field survey data were obtained from 141 employees from various organizations and occupations. The findings suggest that perceptions of interactional justice are related to work-to-family conflict and, as predicted, emotional exhaustion mediated the relationship between interactional justice and work-to-family conflict. Theoretical and practical implications are discussed
