Endogenous opioid system agonists exert amnestic effects in different models of memory. It has been suggested that these amnestic effects may be linked indirectly to state-dependent learning. Accordingly pre-training administration of morphine can impair the retrieval of learned tasks in a state dependent manner, which is reversible by pre test morphine administration. In this study, state depe...

time-dependent schrödinger equation for a 1-d model of hydrogen molecular ion h2+ in intenselaser field linearly polarized along the molecular axis is solved. ionization rates are calculated for differentinitial states. the evolution of electronic wavefunction at fixed inter-nuclear separations are simulated andanalyzed. the results obtained for the ground state of this 1-d model of h2+ show ap...

one of the most important economic factors is potential output. in macroeconomic models and structural studies, the estimation of potential output is necessary for projections and analyzing policy performances. there exist several methods for estimating potential output. meanwhile, its estimation is a difficult and complicated matter. empirical studies and researches show that using various tec...

This study investigated the extent to which the experience of daily stressors was related to women’s age and daily health symptomology, such as flu and cold symptoms. Respondents were 562 women (aged 25–74) who were a part of the National Study of Daily Experiences (NSDE), a telephone diary study examining daily stressful events. The respondents were interviewed by telephone on eight consecutiv...

The importance of forest products to the households who live in or close to the forests has been increasingly recognised over the past ten years. The numbers of people who in some way rely on the forest for survival or livelihood inputs is difficult to assess, and estimates vary widely. The authors of this paper argue that these are not the most appropriate measures of the importance of forests...

This paper describes an approach to crystal engineering based on designing and analyzing hierarchical levels of crystal l ine architecture. The system under study consists of 1:1 co-crystals of melamines and barbituric acids that selfassemble into crystallographically infinite hydrogen-bonded tapes. The formation of structural elements can be rat ional ized and control led using famil iar molec...

Software engineering processes depend on the context they are applied in. Thus, it is risky to determine the best processes for a given project context without empirical data from this context. This report summarizes important issues on the state of the art in empirical studies in order to provide researchers with the background to conduct their own empirical studies and for practitioners to cl...
