A long-standing debate in Pleistocene archaeology concerns the sources of variation in the technology of colonizing hunter-gatherers. One prominent example of this debate is Clovis technology (13,350-12,500 calendar years before present), which represents the earliest widespread and currently recognizable remains of hunter-gatherers in North America. Clovis projectile points appear to have been...

BACKGROUND Our aim was to assess the differences in intraregional prevalence of asthma in adolescents in Split-Dalmatia County to determine asthma risk factors in our population and estimate the specificity and sensitivity of the questionnaire used. MATERIAL/METHODS We conducted the study using the European Community Respiratory Health Survey II short questionnaire supplemented by some questi...

In this paper a new approach to the problem of edge preserving smoothing is proposed and evaluated. The new algorithm is based on the combined forward and backward anisotropic diffusion with incorporated time dependent cooling process. This method is able to efficiently remove image noise while preserving and enhancing image edges, lines and corners. The new method has been applied for the deno...

Water turbidity and suspended sediment concentration (SSC) are commonly used as part of marine monitoring and water quality plans. Current management plans utilise threshold SSC values derived from mean-annual turbidity concentrations. Little published work documents typical ranges of turbidity for reefs within open coastal waters. Here, time-series turbidity measurements from 61 sites in the G...

A multiregion dynamic computable general equilibrium model is constructed to analyze effects of the Southern Common Market (MERCOSUR) on the member countries as well as third-party nonmember countries. The model is based on intertemporal optimization behaviors of consumers and firms with eight endogenously specified regions. By taking into account dynamic general equilibrium adjustments, we obs...
