This paper presents aspects of the coordination chemistry of mono- and divalent manganese complexes supported by the anionic tris(phosphino)borate ligand, [PhBP(i)(Pr)3] (where [PhBP(i)(Pr)3] = [PhB(CH(2)P(i)Pr2)3]-). The Mn(II) halide complexes, [PhBP(i)(Pr)3]MnCl (1) and [PhBP(i)(Pr)3]MnI (2), have been characterized by X-ray diffraction, SQUID magnetometry, and EPR spectroscopy. Compound 2 s...

Orthovanadate is a small toxic molecule that competes with the biologically important oxyanion orthophosphate. Orthovanadate resistance arises spontaneously in Saccharomyces cerevisiae haploid cells by mutation in a number of genes. Mutations selected at 3 nM sodium orthovanadate have different degrees of vanadate resistance, hygromycin sensitivity, detergent sensitivity and sporulation defects...

The objective of this study was to analyze the behavior of autonomic modulation before, during and after the Modified Wingate Test (WanMT), through the analysis of Heart Rate Variability (HRV). Six volunteers between the ages of 40 and 70, post-revascularization procedures (angioplasty and/or surgery, mean duration 10 months), were submitted to supervised training for at least 10 to 14 months. ...

We have investigated cyanide-based metal complexes, which were synthesized by combining [M(CN)4]2- (M = Pt, Pd, Ni) or [MN(CN)4]2- Mn, Re) with complex cations, ions, and organic focusing on their dynamic structures such as thermal expansion (TE) phase transition. For example, FePd(CN)4 is a three dimensional framework consisting of four-coordinate iron(II) nodes. This cyanide demonstrates larg...

Over the last decades or so, artificial neural networks (ANNs) have become one of the most promising tools for modelling hydrological processes such as rainfall-runoff processes. In most studies, ANNs have been demonstrated to show superior result compared to the traditional modelling approaches. They are able to map underlying relationships between input and output data without detailed knowle...

Sampling permutations from Sn is a fundamental problem from probability theory. The nearest neighbor transposition chain Mnn is known to converge in time Θ(n log n) in the uniform case [18] and time Θ(n) in the constant bias case, in which we put adjacent elements in order with probability p 6= 1/2 and out of order with probability 1− p [2]. Here we consider the variable bias case where the pro...

As special depositional environments which are adjacent to the seas, deltas have provided a field for human habitat establishment. Geomorphic features of deltas are in constant transformation due to their dynamic features. Constructing dams on rivers can intensify these changes and cause either negative or positive consequences. Minab delta in Hormozgan Province of Iran is a round or crescent-s...

Lithium-ion batteries are commonly used in electric vehicles, mobile phones, and laptops because of their environmentally friendly nature, high energy density, long lifespan. Despite these advantages, lithium-ion may experience overcharging or discharging if they not continuously monitored, leading to fire explosion risks, cases overcharging, decreased capacity lifespan, overdischarging. Anothe...
