Correlation Between Vinyl Content of Recycled HDPE and Polymer Degradation: An NMR Approach
Journal of Applied Polymer Science, EarlyView.The degradation behavior of high‐density polyethylene (HDPE) during recycling depends on its vinyl group content. This study shows that 1H NMR spectroscopy enables accurate assessment of vinyl groups unlike FTIR. Changes in melt flow and molecular weight with multiple processing are linked to vinyl content which could enable tailor‐made re‐additivation

Shocks and Government Beliefs: The Rise and Fall of American Inflation [PDF]
We use a Bayesian Markov Chain Monte Carlo algorithm to estimate a model that allows temporary gaps between a true expectational Phillips curve and the monetary authority's approximating non-expectational Phillips curve.

Gadjah Mada International Journal of Business, 2010 A series of relatively high inflation characterize Indonesian economy, especially during the economic crisis. Economists generally agree that high inflation is one of the major economic problems, and that economic authorities need to cope with such a ...

The early history of the Phillips curve [PDF]
The Phillips Curve depicts a relationship between inflation and unemployment in graphical or equation form. In a previous article (see the March /April issue of this Review), Thomas Humphrey catalogued the various formulations of the relationship that ...

Procedia Economics and Finance, 2016 AbstractThis paper aims to analyse the cointegration and causality relationships between inflation, GDP and unemployment by using Markov Switching –VAR and Markov Switching Causality tests for the period from 1957(2) to 2014(3) in USA. This study complements previous empirical papers.

Polyethylene Melt Rupture and Slip in Simple Shear: A Visual and Mechanistic Study
Journal of Applied Polymer Science, EarlyView.Slip velocity transient curve (left) with images of the specimen at different times during a simple shear experiment. On the right, schematics illustrate the sample and its side view before and after simple shear. ABSTRACT Melt rupture of a bimodal molecular weight distribution polyethylene is studied under simple shear via flow visualization ...

From Phillips curve to wage curve [PDF]
In most traditional macro-economic models of the Netherlands the wage equation is specified by a Phillips curve, in which wage growth is negatively related to the unemployment rate.

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola
The Anatomical Record, EarlyView.Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Inside and Outside Bounds: Threshold Estimates of the Phillips Curve [PDF]
There have been several instances over the past 40 years when large movements in the unemployment rate have elicited little response in the inflation rate. Such instances, while casting doubt on the tradeoff implied by the linear Phillips curve, are also

The Estimation of Traditional Phillips Curve
Ekonomika, 2023 This article presents theoretical foundations for original Phillips curve formulation and an empirical investigation, where the structure of the theoretical model serves as a template for the creation of the empirical model.For a couple of decades the majority of empirical Phillips curve type assessments are performed using the New Keynesian Phillips ...
