global warming has brought about changes in meteorological variable time series. these changes, accompanied with serious human intervention in nature, has resulted in hydrological changes. so the effects can be tracked down by the trend of the time series. the purpose of this study is to analyze and compare the monthly and annual trends of temperature, precipitation as well as stream flow time ...

BACKGROUND Traction has been suggested to be an effective treatment for symptoms of neck disorder in patients with no contraindications. However, according to previous researches, the effectiveness of traction is controversial, particularly compared to other conservative treatments. This trial was conducted to evaluate the effect of sustained traction, using an over-the-door home cervical tract...

This paper revisits the conclusion instability problem identified by Kitchenham, Foss, Myrtveit et.al.; i.e. conclusions regarding which software effort estimation method is “best” is highly contingent on (1) the evaluation criteria and (2) the subset of the data used in the evaluation. Using non-parametric methods (the Mann-Whitney U test), we show how to avoid conclusion instability. This pap...

Regression analysis is known as statistical methods applied to model and analyze the relationship between variables. method can be examined parametric, non-parametric semiparametric regression methods.
 The parametric assumes that dependent variable in a linear with independent variables shape of known. If these assumptions are not met, applied. However, cause difficulties especially inter...

Introduction: Nowadays, the main focus of dental studies is on adhesive dental materials; since clinical long-term success of bonded restorations depended more on marginal microleakage minimization. So, the aim of this study was Evaluation of Diode laser irradiation effect on microleakage in class V composite restoration before and after adhesive application. Materials and methods: In this in v...

The paper considers methods of parametric optimization a dynamical system, which is described by system differential equations. gradient the functional in form Boltz found, basis such as descent. Another method based on application sensitivity function.

Among worldwide tropical forest ecosystems, the Atlantic of Brazil stands out as a highly fragile area and biodiversity hotspot, with high degree endemism. The Caparaó National Park is an important conservation for this biome, where recent studies have found new species animals plants, including endemic vulnerable ones. We analyzed interannual seasonal trends in vegetation its buffer zone, usin...
