Capital Flows to Latin America and the Caribbean: 2014 Overview

Divergence in macro trends and in monetary policy in advanced economies was a dominant driver of rates and currencies in emerging markets in 2014. Diverging macroeconomic developments were reflected in different monetary policy actions in 2014, with the European Central Bank (ECB) and the Bank of Japan (BOJ) moving in the opposite direction of the U.S. Federal Reserve. The unwinding of the U.S. monetary stimulus, while the ECB and the BOJ step up their monetary stimulus, has underpinned an appreciation by the U.S. dollar, in which most commodities are priced. Latin American markets, which started the year under pressure from fears of the U.S. Federal Reserve tapering off its quantitative easing program and concerns over stability, ended 2014 under pressure from a stronger U.S. dollar. However, there are many signs that a slowdown in LAC financial markets – particularly debt markets, which have been breaking records in debt issuance for the past six years – is under way. The region’s growth prospects look somewhat brighter in 2015 relative to 2014, but a strengthening U.S. dollar, uneven global growth and weakness in commodity prices are skewing the risk toward the downside for the 2015 forecasts across the region.

Capital Flows to Latin America and the Caribbean: Recent Developments

This document, prepared by the Economic Commission for Latin America and the Caribbean (ECLAC) Washington Office, presents and analyzes the most recent developments (third quarter of 2015) concerning capital flows to Latin America and the Caribbean.

Capital Flows to Latin America and the Caribbean. 2015 Overview

This report provides an overview of Latin America and Caribbean’s access to the cross-border debt markets in 2015. The main developments of the year are described through charts and tables, revealing the lowest annual issuance since 2009, higher spreads than in the previous year and a trend towards lower credit ratings.

Capital Flows to Latin America and the Caribbean. Q1 2016

Market sentiment and portfolio flows to Latin America and the Caribbean (LAC) ended the first quarter of 2016 on a more optimistic note than it started. There was a large rally in LAC assets in March, but its intensity was also a function of the very challenging start of the year, when credit and equity investors were deeply concerned about the risk of further slowdown in China’s GDP and the possibility of further devaluation.

Generalized integral transform solution for hydrodynamically developing non-Newtonian flows in circular tubes

ABSTRACT: The Generalized Integral Transform Technique (GITT) is applied to the solution of the momentum equations in a hydrodynamically developing laminar flow of a non-Newtonian power-law fluid inside a circular duct. A primitive variables formulation is adopted in order to avoid the singularity of the auxiliary eigenvalue problem in terms of Bessel functions at the centerline of the duct when the GITT approach is applied. Results for the velocity field and friction factor-Reynolds number product are computed for different power-law indices, which are tabulated and graphically presented as functions of the dimensionless coordinates. Critical comparisons with previous results in the literature are also performed, in order to validate the numerical codes developed in the present work and to demonstrate the consistency of the final results.

A Law of the Wall Formulation for Recirculating Flows

ABSTRACT: This work presents a new law of the wall formulation for recirculating turbulent flows. An alternative expression for the internal length which can be applied in the separated region is also presented. The formulation is implemented in a numerical code which solves the k-e model through a finite volume method. The theoretical results are compared with the experimental data of Vogel and Eaton (J. of Heat Transfer, Transactions of ASME, vol.107, pp. 922-929, 1985). The paper shows that the present formulation furnishes better results than the standard k-e formulation.

Law of large numbers for certain cylinder flows

We construct new examples of cylinder flows, given by skew product extensions of irrational rotations on the circle, that are ergodic and rationally ergodic along a subsequence of iterates. In particular, they exhibit a law of large numbers. This is accomplished by explicitly calculating, for a subsequence of iterates, the number of visits to zero, and it is shown that such number has a Gaussian distribution.

A Reynolds stress model for turbulent flows of viscoelastic fluids

A second-order closure is developed for predicting turbulent flows of viscoelastic fluids described by a modified generalised Newtonian fluid model incorporating a nonlinear viscosity that depends on a strain-hardening Trouton ratio as a means to handle some of the effects of viscoelasticity upon turbulent flows. Its performance is assessed by comparing its predictions for fully developed turbulent pipe flow with experimental data for four different dilute polymeric solutions and also with two sets of direct numerical simulation data for fluids theoretically described by the finitely extensible nonlinear elastic - Peterlin model. The model is based on a Newtonian Reynolds stress closure to predict Newtonian fluid flows, which incorporates low Reynolds number damping functions to properly deal with wall effects and to provide the capability to handle fluid viscoelasticity more effectively. This new turbulence model was able to capture well the drag reduction of various viscoelastic fluids over a wide range of Reynolds numbers and performed better than previously developed models for the same type of constitutive equation, even if the streamwise and wall-normal turbulence intensities were underpredicted.

Erosion Protection by Calcium Lactate/Sodium Fluoride Rinses under Different Salivary Flows in vitro

This study investigated the effect of a calcium lactate pre-rinse on sodium fluoride protection in an in vitro erosion-remineralization model simulating two different salivary flow rates. Enamel and dentin specimens were randomly assigned to 6 groups (n = 8), according to the combination between rinse treatments - deionized water (DIW), 12 mm NaF (NaF) or 150 mm calcium lactate followed by NaF (CaL + NaF) and unstimulated salivary flow rates - 0.5 or 0.05 ml/min simulating normal and low salivary flow rates, respectively. The specimens were placed into custom-made devices, creating a sealed chamber on the specimen surface connected to a peristaltic pump. Citric acid was injected into the chamber for 2 min, followed by artificial saliva (0.5 or 0.05 ml/min) for 60 min. This cycle was repeated 4x/day for 3 days. Rinse treatments were performed daily 30 min after the 1st and 4th erosive challenges, for 1 min each time. Surface loss was determined by optical profilometry. KOH-soluble fluoride and structurally bound fluoride were determined in specimens at the end of the experiment. Data were analyzed by 2-way ANOVA and Tukey tests (alpha = 0.05). NaF and CaL + NaF exhibited significantly lower enamel and dentin loss than DIW, with no difference between them for normal flow conditions. The low salivary flow rate increased enamel and dentin loss, except for CaL + NaF, which presented overall higher KOH-soluble and structurally bound fluoride levels. The results suggest that the NaF rinse was able to reduce erosion progression. Although the CaL prerinse considerably increased F availability, it enhanced NaF protection against dentin erosion only under hyposalivatory conditions. (C) 2014 S. Karger AG, Basel
