the anxiolytic effect of the flower of echium. amoenum was shown in several experimental studies in mice. the present study was aimed to determine whether tolerance develops to anxiolytic action of e. amoenum in mice. nmri male mice were injected intraperitoneal with hydroalcoholic extract (12.5, 25 and 50 mg/kg) or saline once each day (8 am) for period of 7 days and then tested on light/dark ...

In this paper, a prototype for automatically measuring the atmospheric visibility using a digital camera is described. The dark object approach is used on the images obtained by the camera. In this method, two dark objects must first be identified in the images so that visibility can be derived using the modified Koschmieder formula. Due to inherent camera positioning shifts, the images are not...

tsimpli and dimitrakopoulou (2007) observed that uninterpretable features are unavailable in second language (l2) acquisition after the critical period. in this paper, we verify this claim by providing evidence from persian speaking learners of english as an l2 on the status of resumptive pronouns (rps) as uniterpretable features. unlike english which does not allow rps, persian shows various b...

We present a general description of the scalar field dark matter (SFDM) hypothesis in the cosmological context. The scenario of structure formation under such a hypothesis is based on Jeans instabilities of fluctuations of the scalar field. It is shown that it is possible to form stable long lived objects consisting of a wide range of typical galactic masses around 1012M⊙ once the parameters of...

In this paper we use a generalized version of a method originally proposed by Holz and Wald [1] to investigate the effects from gravitational lensing on Type Ia supernovae measurements. We find that results for different mass distributions in smooth dark matter halos are very similar, making lensing effects predictable for a broad range of density profiles. Also, a sample of 100 supernovae at z...

Saccades during object-related everyday tasks select visual information to guide hand movements. Nevertheless, humans can perform such a task in the dark provided it was automatized beforehand. It is largely unknown whether and how saccades are executed in this case. Recently, a long-term memory (LTM)-based direct control mode of attention during the execution of well-learned sensorimotor tasks...
