By a sleeping bag for a baby snake in d dimensions we mean a subset of Rd which can cover, by rotation and translation, every curve of unit length. We construct sleeping bags which are smaller than any previously known in dimensions 3 and higher. In particular, we construct a three-dimensional sleeping bag of volume approximately 0.075803. For large d we construct d-dimensional sleeping bags wi...

BACKGROUND About one-third of U.S. children are overweight or obese and the number is even higher among Hispanics children (41%). In this regards, the time spent in sedentary behaviours is higher among Hispanic children versus non-Hispanic white children. But whether the home environment contributes to the obesity disparity among Hispanic children through the promotion of sedentary behaviours a...

In this work we prove a shape theorem for a growing set of Simple Random Walks (SRWs) on Z d , known as frog model. The dynamics of this process is described as follows: There are active particles, which perform independent SRWs, and sleeping particles, which do not move. When a sleeping particle is hit by an active particle, it becomes active too. At time 0 all particles are sleeping, except f...

objective: insomnia is accompanied by several health complications and the currently used soporific drugs can induce several side effects such as psychomotor impairment, amnesia, and tolerance. the present study was planned to investigate the sleep prolonging effect of pinus eldarica. materials and methods: hydroalcoholic extract (hae) of p. eldarica, its water fraction (wf), ethyl acetate frac...

background insomnia or sleeplessness is a disorder characterized by a personal incapability to falling or staying asleep for a desirable period of time, therefore disturb in quality of life. objectives the present study was carried out to investigate the effect of hydro-alcoholic extract of nepeta glomerulosa and its fractions on sleep-prolonging. materials and methods the extract and its fract...

The petroleum ether (PE), chloroform (CH), ethanol (ETH) and water extracts of E. arvense stems were evaluated for anti-anxiety activity in mice using elevated plus maze model. Ketamine induced hypnosis and actophotometer was used to evaluate sedative effect with various extracts in mice. The results were compared with standard drug diazepam. The ethanolic extract of E. arvense (50 and 100 mg/k...
