Research in programming has focused in the study of stimuli that affect sensitive periods of development such as prenatal and neonatal stage. We previously showed that exposure to estradiol valerate to female rats during ...

The objective of this paper is to develop and test a model of cost estimating for the shell and tube heat exchangers in the early design phase via the application of artificial neural networks (ANN). An ANN model can help ...

Set Covering Problem and Set Partitioning Problem are models for many important industrial applications. In this paper, we solve some Operational Research benchmarks with Ant Colony Optimization using a new transition rule. ...

The interaction of the ethyl xanthate (EX) anion with a copper electrode in a borate buffer solution, pH 9.2, has been investigated by cyclic voltammetry (CV), electrochemical quartz crystal microbalance (EQCM), electrochemical ...

In this paper, a new type of mathematical model to represent certain processes with impulsive dynamic behavior is introduced. The main assumption is that the next impulse time is determined by three fundamental elements: ...

The Birnbaum-Saunders (BS) model is a life distribution with interesting properties and applications in several fields. This has transformed the BS model in an important research focus in recent decades. However, the sum ...

The synthesis, characterization, X-ray crystal structure, and study of the reactivity of the novel cyretrenyl ligand [{(μ5-C 5H4-2-C5H4N) }Re(CO) 3 (1) with Pd(OAc) 2 or [MCl2(DMSO) 2] (M = Pd, Pt) are reported. These ...

A new record of Pseudocarcharias kamoharai off northern Chile is reported. Data on selected measurement are provided. This record confirms the southern limit distribution of this species in the Southeastern Pacific Ocean. ...
