based on the extensive application of peganum harmala (p.h) seeds in the asian traditional medicine, we tried to investigate its possible anxiety effect. method: the effect of p.h. extract inhalation was evaluated in adult male rats using elevated plus-maze apparatus. the humidity of prepared ethanol extract was 37%. animals in different groups (n=6) received 2, 4, 6, 12 or 18 gr/ml doses of th...

introduction: this study aimed to examine the effects of induced inflammatory tooth pain on anxiety level in adult male rats. methods: the mandibular incisors of 56 adult male rats were cut off and prefabricated crowns were fixed on the teeth. formalin and capsaicin were injected intradentally to induce inflammatory tooth pain. diazepam treated group received diazepam 30 minutes before intraden...

This paper surveys some common state space models used in macroeconomics and finance and shows how to specify and estimate these models using the SsfPack algorithms implemented in the S-PLUS module S+FinMetrics. Examples include recursive regression models, time varying parameter models, exact ARMA models and calculation of the Beveridge-Nelson decomposition, unobserved components models, stoch...

Now welcome, the most inspiring book today from a very professional writer in the world, statistical computing an introduction to data analysis using s plus. This is the book that many people in the world waiting for to publish. After the announced of this book, the book lovers are really curious to see how this book is actually. Are you one of them? That's very proper. You may not be regret no...

We describe extensions to the nonlinear modeling facilities in release 3 of S and Splus. These extensions provide classesand methods for fitting and analyzing nonlinear mixed effects models with the two-stage estimation method described by Lindstrom and Bates (1990). They are implemented in a combination of S and C code and complement the classes and methods for the linear mixed effects model t...

Analyses of National Highway Traffic Safety Administration’s Fatality Analysis Reporting System (FARS) and National Automotive Sampling System (NASS)/General Estimates System (GES) data from 2002 – 2006 revealed specific performance errors and combinations of driver, vehicle, and roadway/environmental characteristics associated with older drivers’ crashes at intersections. For subsets of the tw...

The supersymmetric flavor, CP and Polonyi problems are hints that the fundamental scale of the soft supersymmetry breaking parameters may be above a TeV, in apparent conflict with naturalness. We consider the possibility that multi-TeV scalar masses are generated by Planckor unification-scale physics, and find the conditions under which the masses of scalars with large Yukawa couplings are driv...

This paper analyzes the welfare use of Turkish immigrants and natives in Germany. After a brief description of the system of minimum income protection and its recent reform we use data from the German Socio-Economic Panel Study to investigate the correlates of transfer receipt for the two subsamples. Immigrants of Turkish origin have a higher propensity to use welfare benefits than natives. Aft...
