Allergic bronchopulmonary aspergillosis (ABPA) is a complex hypersensitivity reaction observed in asthma as well as cystic fibrosis (CF) patients due to the colonization of the airways by Aspergillus fumigatus. While ABPA is most commonly observed in CF patients (2-9%), it is seen at a rate of 1-2% in patients diagnosed with asthma. ABPA is mostly seen in steroid dependent adult asthma patients and has rarely been reported in pediatric asthma patients.

Mortality rate of the crush victims in the Marmara earthquake of August 1999 was compared with the conclusions arrived after making thermodynamic assessment of the data acquired in the previous earthquakes. Entropic age concept was found very helpful while assessing the data. Mortality rate in the age group of 0-9 years old crush victims was 0 because the basal metabolic rate (BMR) of these children was low.

Millijoule-scale pulses of multicycle terahertz radiation (MC-THz) are increasingly being pursued as drivers for applications requiring high-fields and high spectral brightness. An attractive approach for generating high peak-power MC-THz pulses is nonlinear optical down-conversion of laser pulses in periodically-poled crystals. A principal limitation to the yield, however, is the small (sub-centimeter) apertures of commercially-available crystals which restrict the amount of laser energy that can be used.
