Arabia Terra is an ancient and large terrain which is located north of the Martian equator. Due to its ancient nature, it is heavily cratered, and these craters hold evidence of geologic processes during Mars’ history. During periods of high obliquity (>35°) it has been suggested that polar ice migration can occur at the lower latitudes. By investigating the impact craters within a localized area in the equatorial region of Arabia Terra, it can be determined how far this migration once occurred. This study aimed to investigate craters ≥1 km in diameter within the 0°N–10°N, 340°E–350°E area of Arabia Terra and determine the frequency of glacial and fluvial morphologies within this region. We divided the search area into two sections, 0°N–5°N, 340°E–350°E and 5°N–10°N, 340°E–350°E, to help identify any latitudinal variations between the glacial and fluvial morphologies.

Disaster literature has experienced a rapid evolution from hackneyed tales of death and destruction wrapped in florid story lines into a diverse scholarly palette redolent with social, political, economic, and cultural meaning. Disasters offer great explanatory power and a useful lens to examine American culture. The great Mississippi flood of 1927 was one of the most destructive river floods in U.S. history and has been extensively studied in popular and scholarly texts. In The Flood Year 1927, Susan Scott Parrish, a professor of English and literature at the University of Michigan, eschews a pat retelling of the 1927 flood in favor of a multidisciplinary approach examining “how this disaster took on form and meaning … across multiple media platforms” (p. 3). The shape and style this disaster took, according to Parrish, were unique to the modern age and mediated in the pages of local and national press, the broadcasts of radio programs, vaudevillian performances, literature, blues lyrics, and political cartoons.

A standard technique for laparoscopic ventral hernioplasty (peritoneal onlay using an expanded polytetrafluoroethylene [ePTFE] patch for hernias >/=4 cm2) is being used in a prospective, multicenter, long-term study. Demographic, operative, and postoperative data were collected and analyzed. Follow-up clinical evaluations were conducted 7-10 days, 4 weeks, 6 months, 1 year, and then annually after surgery in all patients. In the first 2 years of the study, 144 patients were enrolled; nine were lost to follow-up. The mean operating time was 120 min. The mean follow-up was 222 days (range 5-731). Postoperative complications were five infections, three cases of prolonged ileus, one bowel obstruction, 23 seromas (15 resolved without intervention), and six hernia recurrences. Hospital discharge occurred a mean of 2.3 days after surgery and return to normal activity a mean of 15 days postoperatively. Laparoscopic prosthetic ventral hernioplasty avoids the large wound required in open repairs, with attendant complications and recurrences, and appears safe, especially if an ePTFE mesh is used. Compared with conventional open ventral hernioplasty, the laparoscopic technique may also allow shorter hospitalization and a quicker return to normal activities after surgery.

The authors provide a basis for understanding BIT related and MMW (millimeter wave) system attributes which offer potential for transportability of current RF/microwave BIT concepts. A comparison of MMW and microwave technology provides a basis for identifying areas where there may be opportunity for the transfer of microwave BIT technology and testability techniques to MMW as well as areas where there is need for new MMW BIT technology development. The authors also describe the current status of device technology, design tools, and implementation techniques applicable to MMW BIT. It is noted that the advent of total MMW systems fabricated on a single monolithic substrate greatly increases the importance of testability and BIT.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
