A Full Uterus: Hematometra from Cervical Scarring

A 29-year-old female presented with abdominal pain, nausea, and vomiting. She reported no menstrual period for one year. She did report monthly episodes of severe cramping. A loop electrosurgical excision procedure was performed approximately 10 months prior. On pelvic exam, a smooth cervix with scarring over the os was visualized with no evidence of cervical opening. A pelvic ultrasound showed an enlarged uterus with contents within the endometrial cavity likely representing hemorrhage of different ages and ongoing bleeding. Gynecology was consulted and performed an incisional opening of the cervix. The patient was diagnosed with hematometra from scarred cervical os

Telescope Bibliographies: an Essential Component of Archival Data Management and Operations

Assessing the impact of astronomical facilities rests upon an evaluation of the scientific discoveries which their data have enabled. Telescope bibliographies, which link data products with the literature, provide a way to use bibliometrics as an impact measure for the underlying data. In this paper we argue that the creation and maintenance of telescope bibliographies should be considered an integral part of an observatory's operations. We review the existing tools, services, and workflows which support these curation activities, giving an estimate of the effort and expertise required to maintain an archive-based telescope bibliography.Comment: 10 pages, 3 figures, to appear in SPIE Astronomical Telescopes and Instrumentation, SPIE Conference Series 844

CDA and Continuing Dental Education on Company Time

As a Certified Dental Assistant (CDA), the obligation to obtain Continuing Dental Education (CDE) credits to maintain one’s certification is an annual occurrence. Through the Dental Assisting National Board (DANB), annual renewals for CDAs consist of a fee, CPR certification, and one’s CDE acquisition. Working for a nonprofit community health center, Terry Reilly Health Services, I find it crucial to be able to share with my colleagues resources on finding CDE opportunities. Thus this led to the creation of my CDA quickstart guidebook to ensure staff have the correct resources for pursuing or maintaining a CDA certification. It is a compilation of crucial courses that satisfy DANB requirements. I’m hoping that my work acts as a cushion for how stressful it can be to obtain CDE credits alone

Music in the landscape : ban amphitheater and outdoor exhibit space for the Rock and Roll Hall of Fame

Information is flowing around us constantly passing through the air; transmitting information, phone calls and Emails. Our interaction with digital media is becoming increasingly prevalent in our day-to-day lives and continues to permeate our offices, homes and play spaces. Yet few designs begin to interface with media and the processing or transmittal of information between the user and the surfaces, which define our world. This study proposes to create an outdoor digital landscape, which is part of a larger performance area. This space utilizes digital media to allow speakers, musical groups, and other performers another dimension to express their material. The performance space and digital presentation area should be viewed as an entire experience away from that of reality. The goal of the project is to continue to blur the lines between information and form, and to play with what we conceive of as reality. The project will provide an outlet for digital artists as well as a chance to experiment with form, space and information and our ability as humans to influence process and transmit information between surfaces.Music will be the ignition for this process; extracting bits of data and information from musical pieces and applying that to the design of this space. Music is a part of our daily lives and provides another dimension that can be implemented in the design process. Information will be extracted from musical pieces and implemented as abstracts within the final design. In addition to the experimental design and artistic expression, an educational component may be realized. In an educational environment, patron’s opinions and views of what music is and can be, would be expanded, and an additional respect for the music that drives design and serves as a soundtrack for our world.Thesis (B.L.A.)College of Architecture and Plannin

Design, Fabrication, and Measurement of a Multiple-Input Multiple-Output (MIMO) Antenna for Mobile Communication

This thesis presents the design, fabrication and characterization of a multiband uniplanar MIMO antenna for hand-held mobile communication devices on LTE, WLAN, and WMAN networks. The antenna design methodology combined a variety of broadbanding techniques that resulted in a single-layer hybrid monopole antenna coupled to a meander line element and parasitic structures. The 115×55×1.54 mm antenna was fabricated using an FR4 composite material and occupies only a fractional volume within the size of an average cellular phone allowing ample space to integrate with existing hardware. Characterization of the MIMO antenna included input impedance, scattering parameters and radiation pattern cross sections that were all measured from 500-6500 MHz inside an anechoic chamber. The measurement results indicated four main operating regions of the multiband antenna centered at 875 MHz, 2300 MHz, 3500 MHz, and 5700 MHz with bandwidths of 240 MHz, 740 MHz, 190 MHz, and 370 MHz respectively. Scattering parameter measurements demonstrated excellent coverage of the desired communication spectrum, being able to operate on 30 of the 42 defined LTE bands, as well as common WLAN and WMAN bands. The radiation pattern cross sections in each of the operating regions showed non-directional behavior that is desirable for mobile communication devices. Additionally the envelope correlation coefficient calculated from the measured complex scattering parameters verified that the MIMO antenna achieved good system diversity. Overall, this work resulted in a multiband uniplanar MIMO antenna system suitable for hand-held mobile communication devices. Utilizing cost effective materials and simple geometries allowed fabrication using common methods. The novel antenna can support the high capacity required from evolving communication systems and represents a practical option for use within future generations of mobile devices
