Britain and other European governments have been accused of underestimating the health risks from shipping pollution following research which shows that one giant container ship can emit almost the same amount of cancer and asthma-causing chemicals as 50m cars.
Polysomnography (PSG), a type of sleep study, is a multi-parametric test used in the study of sleep and as a diagnostic tool in sleep medicine. The test result is called a polysomnogram, also abbreviated PSG. The name is derived from Greek and Latin roots: the Greek ÏÎ¿Î»ÏÏ (polus for many, much, indicating many channels), the Latin somnus (sleep), and the Greek Î³ÏÎ¬ÏÎµÎ¹Î½ (graphein, to write).
Since the Spring of 2001, Plant SuperGroup (PSG) has provided a forum for informal presentation and discussion by grad students, post-docs and faculty working in experimental plant biology at CSU and in the Front range of the Rockies. PSG is also a place for plant biologists to mingle informally and make contacts. Meetings are twice per semester, on Friday afternoons and are attended by most plant researchers at CSU. Each meeting has two or three 25-30 min talks. Lively but friendly discussions usually follow in which students and post docs are especially invited to take part. Each meeting has drinks and food items, which are provided by a faculty member. All attendees are encouraged to mingle and meet before and between the talks.
