GESTÃO DE RELAÇÕES ESTRATÉGICAS INTERPESSOAIS NAS ALIANÇAS CORPORATIVAS (GRE): SINERGIA DE VALOR NA GESTÃO INTEGRADA DE RH

Este trabalho pretende apresentar e compreender o papel da gestão estratégica de pessoas, dentro de uma visão que contempla as relações interorganizacionais fora dos limites tradicionais de seu escopo nas empresas e expandidas além das dimensões formais e fronteiras que permeiam uma organização. Este estudo estabelece a importância e sistemáticas da gestão de atividades de RH, compartilhadas com a cadeia de valor externa, analisando-as nas práticas com os canais de distribuição junto aos clientes. Esta área organizacional é denominada pelo autor de GRE - Gestão das Relações Estratégicas. Baseando-se em uma pesquisa exploratória em 26 empresas, organizada a partir de cinco empresas nodais e seus canais de distribuição, utilizou-se a aplicação de um questionário de pesquisa com escala Likert e entrevistas pessoais semi-estruturadas junto aos gestores e profissionais de diversas áreas, bem como o tratamento estatístico dos dados com o programa SPSS, indicando a confirmação das questões de pesquisa relativas a GRE como sendo uma proposta de expansão das atividades do RH, focando em como se pode e devem entregar valor para a organização, para os aliados estratégicos, os investidores e fundamentalmente para os clientes.(AU)

Elettrodeposizione di catalizzatori a base di Rh su schiume e fibre metalliche di FeCrAlloy per la produzione di syngas

The preparation of structured catalysts active in the catalytic partial oxidation of methane to syngas, was performed by electrosynthesis of hydroxides on FeCrAlloy foams and fibers. Rh/Mg/Al hydrotalcite-type compounds were prepared by co-precipitation of metallic cations on the support and successive calcination. Electrochemical reactions have been studied during the electrodeposition by linear sweep voltammetry. The experiments were performed at supports immersed in KNO3, KCl, Mg2+ and Al3+ aqueous solutions, starting by different precursors (nitrate and chlorides salts) and modifying the Mg/A ratio. Rh/Mg/Al hydrotalcite-type compounds were deposited on metal foams by applying a -1.2V vs SCE potential for 2000s with a nitrate solution of 0.06M total metal concentration. Firstly it was studied the effect of Mg on the coating propierties, modifying the Rh/Mg/Al atomic ratio (5/70/25, 5/50/45, 5/25/70 e 5/0/95). Then the effect of the amount of Rh was later investigated in the sample with the largest Mg content (Rh/Mg/Al = 5/70/25 and 2/70/28).The results showed that magnesium allowed obtaining the most homogeneous and well adherent coatings, wherein rhodium was well dispersed. The sample with the Rh/Mg /Al ratio equal to5/70/25 showed the best catalytic performances. Decreasing the Rh content, the properties of the coating were not modified, but the catalytic activity was lower, due to a not enough number of active sites to convert the methane. The work on metal fibers focused on the effect of precursor concentration, keeping constant composition, potential and synthesis time at the values of Rh/Mg/Al =5/70/25, -1.2V vs SCE and 1000s. However fibers geometry did not allow to obtain a high quality coating, even if results were quite promising.

Sn@Pt and Rh@Pt core–shell nanoparticles synthesis for glycerol oxidation

The development and optimization of electrocatalysts for application in fuel cell systems have been the focus of a variety of studies where core–shell structures have been considered as a promising alternative among the materials studied. We synthesized core–shell nanoparticles of Sn x @Pt y and Rh x @Pt y (Sn@Pt, Sn@Pt2, Sn@Pt3, Rh@Pt, Rh@Pt2, and Rh@Pt3) through a reduction methodology using sodium borohydride. These nanoparticles were electrochemically characterized by cyclic voltammetry and further analyzed by cyclic voltammetry studying their catalytic activity toward glycerol electro-oxidation; chronoamperometry and potentiostatic polarization experiments were also carried out. The physical characterization was carried out by X-ray diffraction, energy-dispersive X-ray spectroscopy, X-ray photoelectron spectroscopy, and transmission electron microscopy. The onset potential for glycerol oxidation was shifted in 130 and 120 mV on the Sn@Pt3/C and Rh@Pt3/C catalysts, respectively, compared to commercial Pt/C, while the stationary pseudo-current density, taken at 600 mV, increased 2-fold and 5-fold for these catalysts related to Pt/C, respectively. Thus, the catalysts synthesized by the developed methodology have enhanced catalytic activity toward the electro-oxidation of glycerol, representing an interesting alternative for fuel cell systems.

A novel method to determine new potent angiotensin inhibitor, azilsartan, in human plasma via micelle-enhanced spectrofluorimetry using cremophor RH 40

Purpose: To develop a micelle-enhanced spectrofluorimetric method for the assay of azilsartan (AZL) in bulk form and spiked human plasma without the need for derivatization procedure. Method: The proposed method was based on studying the fluorescence behavior of AZL in Cremophor RH 40 (Cr RH 40) micellar system. The fluorescence intensity was measured at 371 nm after excitation at 264 nm. The proposed procedure was validated according to International Council on Harmonization (ICH) guidelines. Results: In aqueous solution, the fluorescence intensity of AZL was greatly enhanced by more than 3- fold in the presence of Cr RH 40. The fluorescence –concentration plot was linear over the range of 10 – 500 ng.mL-1, with a limit of detection of 3.287 ngmL-1. The proposed method was successfully applied to the determination of AZL in pure powder form and spiked human plasma. The mean recovery of AZL in spiked human plasma using the proposed method was 90.54 ± 1.17 %. Conclusion: The suggested method is highly sensitive and simple, and can easily be applied for the quantification of AZL in pure powder form as well as in biological fluids such as plasma.

Studio della reattività di cluster carbonilici di Rh con sali di Au(I)

Il progetto di tesi si è focalizzato sullo studio della reattività del cluster carbonilico [Rh7(CO)16]3- in presenza del sale Au(Et2S)Cl. Ogni reazione investigata è stata svolta in atmosfera controllata di CO, modificando i rapporti stechiometrici tra il precursore e il sale di Au(I) in diversi solventi. Inizialmente si è tentato di riprodurre la sintesi del cluster bimetallico [Rh20Au7(CO)45]5- già noto, utilizzando Au(Et2S)Cl. Si è poi amplificato lo studio con l’obiettivo principale di sintetizzare nuovi cluster bimetallici ad alta nuclearità. È stato ottenuto un composto nuovo analizzato tramite diffrattometria ai raggi X a cristallo singolo: [Rh22Au3(CO)x]n-. Tramite i dati cristallografici è stato possibile definirne la sola struttura metallica, e nonostante i diversi tentativi, il composto non ha prodotto cristalli migliori per una completa caratterizzazione. Viste le quantità significative di sottoprodotti a bassa nuclearità ottenute nelle reazioni studiate, parallelamente sono state condotte prove di recupero del rodio in quanto metallo prezioso. Infine, è stato ottimizzato un metodo per separare due specie già note con carica negativa simile, [Rh10Au(CO)26]3- e [Rh16Au6(CO)36]4-. Tutti i composti sono stati caratterizzati tramite spettroscopia IR, mentre sul nuovo cluster è stata effettuata anche un’analisi alla spettrometria di massa.

A Doença Hemolítica Perinatal (DHP) caracteriza-se pela hemólise fetal, com suas múltiplas e graves repercussões sobre a vitalidade do feto. É imprescindível que o diagnóstico se antecipe à Doença Hemolítica Perinatal (DHP). É importante avaliar se houve alguma das principais formas de exposição materna ao sangue fetal,para que intervenções e medidas de prevenção sejam realizadas.

Taurine Supplementation Increases K(atp) Channel Protein Content, Improving Ca2+ Handling And Insulin Secretion In Islets From Malnourished Mice Fed On A High-fat Diet.

Pancreatic β-cells are highly sensitive to suboptimal or excess nutrients, as occurs in protein-malnutrition and obesity. Taurine (Tau) improves insulin secretion in response to nutrients and depolarizing agents. Here, we assessed the expression and function of Cav and KATP channels in islets from malnourished mice fed on a high-fat diet (HFD) and supplemented with Tau. Weaned mice received a normal (C) or a low-protein diet (R) for 6 weeks. Half of each group were fed a HFD for 8 weeks without (CH, RH) or with 5% Tau since weaning (CHT, RHT). Isolated islets from R mice showed lower insulin release with glucose and depolarizing stimuli. In CH islets, insulin secretion was increased and this was associated with enhanced KATP inhibition and Cav activity. RH islets secreted less insulin at high K(+) concentration and showed enhanced KATP activity. Tau supplementation normalized K(+)-induced secretion and enhanced glucose-induced Ca(2+) influx in RHT islets. R islets presented lower Ca(2+) influx in response to tolbutamide, and higher protein content and activity of the Kir6.2 subunit of the KATP. Tau increased the protein content of the α1.2 subunit of the Cav channels and the SNARE proteins SNAP-25 and Synt-1 in CHT islets, whereas in RHT, Kir6.2 and Synt-1 proteins were increased. In conclusion, impaired islet function in R islets is related to higher content and activity of the KATP channels. Tau treatment enhanced RHT islet secretory capacity by improving the protein expression and inhibition of the KATP channels and enhancing Synt-1 islet content.

Adipokines: Novel Players In Resistant Hypertension.

Resistant hypertension (RH) is a multifactorial disease, frequently associated with obesity and characterized by blood pressure above goal (140/90 mm Hg) despite the concurrent use of ≥3 antihypertensive drugs of different classes. The mechanisms of obesity-related hypertension include, among others, aldosterone excess and inflammatory adipokines, which have demonstrated a significant role in the pathogenesis of metabolic syndrome and RH. This review aims to summarize recent studies on the role of the adipokines leptin, resistin, and adiponectin in the pathophysiology of RH and target-organ damage associated with this condition. The deregulation of adipokine levels has been associated with clinical characteristics frequently recognized in RH such as diabetes, hyperactivity of sympathetic and renin-angiotensin-aldosterone systems, and vascular and renal damage. Strategies to regulate adipokines may be promising for the management of RH and some clinical implications must be considered when managing controlled and uncontrolled patients with RH.
