Introduction. Deuteronilus Mensae is a ~1000 km wide area along the highland/lowland dichotomy boundary in the northern mid-latitudes of Mars. In this region, features diagnostic of Martian 'fretted' terrain are observed, including lobate debris aprons, lineated valley fill, and concentric crater fill [1-5]. South of Deuteronilus Mensae are the rugged cratered highlands of Arabia Terra and nort...

Viscous flow features, including lobate debris aprons and lineated valley fill, are common ice-related features found across the mid-latitudes of Mars. These commonly along dichotomy boundary around massifs where snow ice can accumulate to topographic lows during periods higher obliquity. We have identified mapped glacial-related reminiscent fill in lower Arcadia Planitia based on morphology, a...

In order to comply with the requirements established by healthcare organization accrediting agencies, radiation protective equipment (e.g., lead aprons, gloves, and collars) utilized by x-ray workers must be periodically evaluated for damage. The objective of such evaluations is to identify and remove from service equipment bearing large holes, tears, etc., that could compromise the safety of i...

Undesired radiation exposure to caregivers is an important problem in radioiodine therapy in thyroid carcinoma patients, especially when patient is non-ambulatory. Special precautions are needed to keep the exposure to caregivers low when higher dose of radioiodine is necessary. Here we present a case-report of a 74-year old male patient with papillary thyroid carcinoma with local invasion and...

OBJECTIVE To assess the availability, practices and knowledge of radiation safety measures among invasive cardiologists in a tertiary care hospital. METHOD A cross sectional survey of invasive cardiologists working in academic institutions was conducted using a questionnaire. RESULTS A total of 28 cardiologists completed the questionnaire with a mean working experience of 10.5 + 7.6 years. ...

BACKGROUND With increasing use of medical radiologic procedures, wearing proper protector should be emphasized to reduce occupational radiation exposures. This research describes the rates of lead apron wearing for radiation protection and assessed occupational factors related to wearing rates for various types of healthcare professionals. METHODS We conducted a self-administered questionnair...
