For decades detection and monitoring of forest and other wildland fires has relied heavily on aircraft (and satellites). Technical advances and improved affordability of both sensors and sensor platforms promise to revolutionize the way aircraft detect, monitor and help suppress wildfires. Sensor systems like hyperspectral cameras, image intensifiers and thermal cameras that have previously bee...

Two main causes of postoperative total hip arthroplasty (THA) dislocation are malposition of the acetabular component within the prosthesis and soft tissue imbalances.1 The direct anterior approach for THA is viewed as advantageous compared with other approaches because, in addition to preserving many of the inherent restraints within the hip joint,2 it allows C-arm fluoroscopy image intensifie...

We found that ethyl gallate purified from a dried pod of tara (Caesalpinia spinosa) intensified beta-lactam susceptibility in methicillin-resistant and methicillin-sensitive strains of Staphylococcus aureus (MRSA and MSSA strains, respectively). This compound and several known alkyl gallates were tested with MRSA and MSSA strains to gain new insights into their structural functions in relation ...

Diagnostic Catheter Procedures In 1958, Mason Sones and his colleagues developed selective coronary angiography and published it as an abstract in Circulation.2 As a cardiologist at the Cleveland Clinic, he performed angiography of the aortic root in a patient with valvular heart disease. Looking directly into the x-ray beam, as was customary in the era before image intensifiers coupled to tele...

Military night vision goggles (NVGs) are image intensifiers normally used when the human operator's visual capabilities are unimpaired by oxygen deprivation. However, mountain search team members and aviators sometimes operate with NVG augmentation at altitudes where hypoxic visual decrement is documented. The objective of this research was to investigate the effects of mild hypoxia on monocula...

Beam monitors using cameras have evolved from qualitative beam observation to precision measurements. After a description of the two main TV standards, the various sensors: TV tubes (Vidicon), solid state sensors (Interline and Frame Transfer CCDs, CMOS and CID X-Y matrices), and Fast Shutter/Intensifiers of the MCP type are reviewed. Comparative resolution measurements for the various sensors ...

This study tested the effects of linguistic qualifiers and intensifiers on the number and types of replies elicited per argument and per challenge posted in online debates. To facilitate collaborative argumentation, thirty-two students (22 females, 10 males) enrolled in a graduatelevel online course classified and labeled their messages as arguments, challenges, supporting evidence, or explanat...

A standard operating microscope was modified with a bandpass infrared filter in the light path and infrared image intensifiers for each of the 2 eyepieces. We evaluated this system for subretinal injections in normal control dogs and those with a mutation in the rhodopsin gene. Rhodopsin-mutant dogs are a model for human autosomal dominant retinitis pigmentosa, and their retinas degenerate fast...
