OBJECTIVES To determine the off-shift sleep strategies of bi-ethnic night-shift nurses, the relationship between these sleep strategies and adaptation to shift work, and identify the participant-level characteristics associated with a given sleep strategy. METHODS African-American and non-Hispanic White female, night-shift nurses from an academic hospital were recruited to complete a survey o...

In Krylov's analytical prediction model, the free field vibration response during the passage of a train is written as the superposition of the effect of all sleeper forces, using Lamb's approximate solution for the Green's function of a halfspace. When this formulation is extended with the Green's functions of a layered soil, considerable computational effort is required if these Green's funct...

In a previous communication, Sheets et al. (1954) have shown that three phenol-resistant organisms, a sporeforming rod, a coccus and a short rod, belonging to the genera Bacillus, Micrococcus and Pseudomonas respectively, were isolated from a trickling filter, operated continuously at 54 C for the treatment of phenolic wastes. The Pseudomonas-like rod predominated over the other two types. A pu...

Rail is one of the most energy efficient and economical modes transportation amongst many. Regular inspection railway track health essential for ensuring robust secure train operations. Investigations delayed discovery pose a serious risk to safe functioning rail transportation. The traditional method manually examining using cart both inefficient susceptible mistakes bias. It imperative automa...

Herein, we use genetic data from 277 sleeper sharks to perform coalescent-based modeling to test the hypothesis of early Quaternary emergence of the Greenland shark (Somniosus microcephalus) from ancestral sleeper sharks in the Canadian Arctic-Subarctic region. Our results show that morphologically cryptic somniosids S. microcephalus and Somniosus pacificus can be genetically distinguished usin...

ONE OF THE GREAT PUZZLES OF SLEEP IS THE EXTENT TO WHICH THE SLEEPER IS AWARE OF EVENTS IN THEIR EXTERNAL ENVIRONMENT. Information processing capabilities at sleep onset and across various depths of sleep are of interest to a general audience, including psychologists, philosophers, and those in the medical field (particularly anesthesiologists). Awareness during sleep is relevant for studies of...

• Increased consumer focus on sleep by education, regulation and patient selfawareness.7 Sleep medicine is a relatively new field that was officially recognized in the 1960s. Today, an estimated 50 million to 70 million Americans suffer from sleep-related problems.1 The first sleep disorder clinic was opened in 19702 at Stanford University by William Dement, MD. Today more than 2,000 sleep cent...
