Coordination properties of vic-isonitrosoimines in their copper (II) and palladium (II) complexes

Preparation and structural characterization of palladium (II) complexes of ligands III-V and copper (II) complexes of III are reported. The elemental analyses of the complexes show that the metal: ligand ratio is 1 : 2. The electrical conductance in acetone shows the non-electrolytic nature of the complexes. The diamagnetic character suggests a gross square-planar geometry for the palladium (II) complexes. Copper (II) complexes are paramagnetic with/~eff.~l'90 B.M. Spectral data suggest that in all the complexes the ligand coordinates to the metal (II) symmetrically through isonitroso-nitrogen and imine-nitrogen, forming a ¡ membered chelate ring. Amine-exchange reactions of the complexes are discussed and compared on the basis of their structures.

La Reforma Catòlica a la muntanya catalana a través de les visites pastorals: els bisbats de Girona i Vic (1587-1800)

La present tesi vol explicar la implantació de la Reforma Catòlica en una sèrie de parròquies rurals dels bisbats de Girona (valls de Ridaura, Bas, Hostoles i Amer) i Vic (El Collsacabra i les valls de Susqueda i Sau), entre 1587 i 1800, des dels bisbes posttrentins Jaume Caçador i Pedro Jaime als il·lustrats Tomàs de Lorenzana i Francisco de Veyan. La documentació principal són les sèries de les visites pastorals conservades a l'Arxiu Diocesà de Girona i l'Arxiu Episcopal de Vic; paral·lelament, s'ha reforçat amb documentació parroquial (llibres sagramentals, consuetes, llibres d'obra i confraries), protocols notarials (notaries de Rupit, Sant Feliu de Pallerols, El Mallol i Amer) i impresos episcopals. Els manaments de les visites pastorals s'han contrastat, amb semblances i diferències, amb els decrets del concili de Trento, de les constitucions provincials tarraconenses i les sinodals gironines i vigatanes, i amb les evidències artístiques, arquitectòniques i arqueològiques. Tots ells han servit per demostrar la lentitud en la implantació del programa tridentí, que s'assoleix, de fet, amb força retard (ben entrat el segle XVIII).

Intramolecular hydrogen bond: Can it be part of the basis set of valence internal coordinates in normal mode analysis?

It has been shown earlier1] that the relaxed force constants (RFCs) could be used as a measure of bond strength only when the bonds form a part of the complete valence internal coordinates (VIC) basis. However, if the bond is not a part of the complete VIC basis, its RFC is not necessarily a measure of bond strength. Sometimes, it is possible to have a complete VIC basis that does not contain the intramolecular hydrogen bond (IMHB) as part of the basis. This means the RFC of IMHB is not necessarily a measure of bond strength. However, we know that IMHB is a weak bond and hence its RFC has to be a measure of bond strength. We resolve this problem of IMHB not being part of the complete basis by postulating `equivalent' basis sets where IMHB is part of the basis at least in one of the equivalent sets of VIC. As long as a given IMHB appears in one of the equivalent complete VIC basis sets, its RFC could be used as a measure of bond strength parameter.

Effect of vacuum-induced coherence on lasing without inversion in an equispaced three-level ladder system

The effects of vacuum-induced coherence (VIC) on the properties of the absorption and gain of the probe field in an equispaced three-level ladder atomic system are investigated. It is found that lasing without inversion (LWI) is remarkably enhanced due to the effect of VIC in the case of the small incoherent pump rate.

Història social de l'escola a la Catalunya central. Vic 1830-1900

En aquesta tesi es valora l'impacte social que comporta per a la ciutat de Vic el bastiment d'un nou sistema educatiu implantat per l'estat liberal en el transcurs del segle XIX. L'estudi s'estructura a partir de: l'anàlisi del discurs i de les accions de les elits locals; de les actituds de les famílies; del sorgiment i consolidació dels i les mestres; i de l'escola com a espai educatiu: Vic esdevé un cas molt particular perquè és capital de bisbat però no de província; perquè exerceix una notable influència sobre el territori i perquè és zona de frontera entre el liberalisme i el carlisme. La tesi valora fins a quin punt tots els agents implicats en la qüestió educativa s'interconecten i com des de l'àmbit local es viuen les transformacions del segle XIX.

Mechanical strain induces the production of spheroid mineralized microparticles in the aortic valve through a RhoA/ROCK-dependent mechanism

Calcific aortic valve disease (CAVD) is a chronic disorder characterized by an abnormal mineralization of the leaflets, which is accelerated in bicuspid aortic valve (BAV). It is suspected that mechanical strain may promote/enhance mineralization of the aortic valve. However, the effect of mechanical strain and the involved pathways during mineralization of the aortic valve remains largely unknown. Valve interstitial cells (VICs) were isolated and studied under strain conditions. Human bicuspid aortic valves were examined as a model relevant to increase mechanical strain. Cyclic strain increased mineralization of VICs by several-fold. Scanning electron microscope (SEM) and energy dispersive X-ray (EDX) analyses revealed that mechanical strain promoted the formation of mineralized spheroid microparticles, which coalesced into larger structure at the surface of apoptotic VICs. Apoptosis and mineralization were closely associated with expression of ENPP1. Inhibition of ENPP1 greatly reduced mineralization of VIC cultures. Through several lines of evidence we showed that mechanical strain promoted the export of ENPP1-containing vesicles to the plasma membrane through a RhoA/ROCK pathway. Studies conducted in human BAV revealed the presence of spheroid mineralized structures along with the expression of ENPP1 in areas of high mechanical strain. Mechanical strain promotes the production and accumulation of spheroid mineralized microparticles by VICs, which may represent one important underlying mechanism involved in aortic valve mineralization. RhoA/ROCK-mediated export of ENPP1 to the plasma membrane promotes strain-induced mineralization of VICs.

Evaluating the usefulness of soil moisture (forecasts) in streamflow prediction for central Texas

The past decade has brought significant advancements in seasonal climate forecasting. However, water resources decision support and management continues to be based almost entirely on historical observations and does not take advantage of climate forecasts. This study builds on previous work that conditioned streamflow ensemble forecasts on observable climate indicators, such as the El Niño-Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) for use in a decision support model for the Highland Lakes multi-reservoir system in central Texas operated by the Lower Colorado River Authority (LCRA). In the current study, seasonal soil moisture is explored as a climate indicator and predictor of annual streamflow for the LCRA region. The main purpose of this study is to evaluate the correlation of fractional soil moisture with streamflow using the 1950-2000 Variable Infiltration Capacity (VIC) Retrospective Land Surface Data Set over the LCRA region. Correlations were determined by examining different annual and seasonal combinations of VIC modeled fractional soil moisture and observed streamflow. The applicability of the VIC Retrospective Land Surface Data Set as a data source for this study is tested along with establishing and analyzing patterns of climatology for the watershed study area using the selected data source (VIC model) and historical data. Correlation results showed potential for the use of soil moisture as a predictor of streamflow over the LCRA region. This was evident by the good correlations found between seasonal soil moisture and seasonal streamflow during coincident seasons as well as between seasonal and annual soil moisture with annual streamflow during coincident years. With the findings of good correlation between seasonal soil moisture from the VIC Retrospective Land Surface Data Set with observed annual streamflow presented in this study, future research would evaluate the application of NOAA Climate Prediction Center (CPC) forecasts of soil moisture in predicting annual streamflow for use in the decision support model for the LCRA.

Visita interprofissional da cardiologia: uma estratégia de educação interprofissional na área da saúde na Universidade Federal do Rio Grande do Norte

The interprofessional education still represents a great challenge for the health education. This paper aims at implementing the Interprofessional Cardiology Visit (VIC, acronym in Portuguese) as a teaching strategy for the interprofessional education in the undergraduate and graduate courses of UFRN (Federal University of Rio Grande do Norte, acronym in Portuguese). It is a prospective and exploratory study held from March 2013 to November 2014, in the cardiology department of HUOL (Portuguese acronym for Onofre Lopes University Hospital), including health professionals from the mentioned hospital (doctor, psycologist, physiotherapist, dentist, social assistant, nutritionist, pharmacist and nurse), undergraduate and graduate students from the health courses of UFRN. The study happened in three parts: interprofessional activity planning; Implementation of the activity “Interprofessional Cardiology Visit (VIC)”; and Activity evaluation, this last one was made through focus groups. The process of planning and implementation of the VIC was described during the implementation phase: 60 meetings in which 1324 participants discussed one specific patient per meeting. After each case presentation, an interprofessional discussion was held, pointing out each professional’s specific point of view towards improving the overall care of that discussed patient. From the focus group analysis, five categories emerged: Recognition of previous participations in interprofessional activities; Conceptual vision of interprofessional activities; Impacts of the VIC to the patient’s care; Contributions of VIC to the professional training; and Challenges of VIC continuation. The making and planning of VIC process has reached its goals, despite of some health professional’s participation not being systematic due to work overload, such as the nurses’ case, as well as schedule difficulties. The VIC was praised as a successful experience and considered an initiative with positive impact for improving the care of patients with heart diseases. It is clear, from analyzing the discourses, that the VIC is a strategy which positively impacts both the care and the teaching. However, some difficulties remain, such as the lack of human resources and the challenge of making it systematic.

RAN-Vic : renal access nurses of Victoria unite.

The Renal Access Nurse has recently become an integral member of the renal health care team in Australia. Research has shown that the introduction of a Renal Access Nurse into dialysis units enhances the referral process for new access, improves survival rates, and success of access creation. Australia has been relatively slow in the introduction of the role of the Renal Access Nurse. The USA, UK and Europe have been utilising Renal Access Nurses in renal units for many years and their roles are firmly entrenched.

The first Renal Access Nurse was introduced in Victoria in 2003, increasing to 7 in 2007. It was evident in 2006 that a networking system for Renal Access Nurses was needed in Victoria, so RAN-Vic was born.

RAN-Vic consists of 6 Renal Access Nurses from the major hubs in Melbourne and Geelong, thus covering a large part of the Victorian dialysis community through satellite units throughout the state.

The group meet quarterly, with the main goals being to network, share ideas, support each other with challenges arising from the new role, benchmark, undertake quality initiatives and education of renal nursing staff. By doing this, we hope to improve outcomes for patients, improve work practices pertaining to renal access, and further redefine the new role.

RAN-Vic is the first of its kind in Australia, providing care for renal access for the dialysis population throughout Victoria. We recommend for all states in Australia to consider forming a Renal Access Group to help improve renal access outcomes.

A way through the dark and thorny thickets? The adjudication of ‘serious injury’ under the narrative tests in the Transport Accident Act 1986 (Vic) and the Workplace Injury Rehabilitation and Compensation Act 2013 (Vic)

The so-called narrative test provides the means by which injured persons who satisfy the statutory and common law definition of serious injury may bring proceedings for common law damages under s 93 of the Transport Accident Act 1986 (Vic) and s 134AB of the Accident Compensation Act 1985 (Vic) (or, for injuries after 1 July 2014, under ss 324-347 of the Workplace Injury Rehabilitation and Compensation Act 2013 (Vic)). These are among the most litigated provisions in Australia. This article outlines the legislative and political background to these provisions, the provisions themselves, and an account of the statutory and common law requirements needed to satisfy the provisions.
