The Impact of COVID-19 on the Global and Intra-Commonwealth Trade in Goods

This paper employs the gravity model of international trade to examine the effect of the COVID- 19 pandemic on global and intra-Commonwealth trade flows. It uses bilateral monthly exports data at the HS6 level and the number of COVID-19 cases and deaths, as well as the stringency of measures taken to contain the virus, to estimate the effect of the pandemic on Commonwealth countries’ trade. The study finds that the incidence of COVID-19 in both exporting and importing countries has impacted on Commonwealth trade flows and that the extent of the effect varies with the development level of trading partners. High numbers of COVID-19 cases, including deaths, in low-income importing countries led to a reduction in Commonwealth exports, while a high inci- dence of COVID-19 in high-income importing countries led to with an increase in their exports. The incidence of COVID-19 in an exporting country was also found to impact on trade among a global sample of countries. Restrictions aiming to contain COVID-19 in high-income countries were associated with an increase in Commonwealth countries’ trade. Short-term projections of trade trends point towards a negative change in both exports and imports of Commonwealth countries. The study also proposes a set of policy options and recommendations targeting sustain- able recovery and building resilience in Commonwealth economies

Efectos de la existencia de capa elástica en los sistemas de césped artificial de tercera generación y la velocidad de carrera sobre la respuesta biomecánica de atenuación de impactos en jugadores de fútbol

Accésit Congreso SIBB 2015El objetivo del estudio fue comparar la influencia de la capa elástica con otros componentes estructurales sobre la magnitud y atenuación de impactos en diferentes sistemas de césped artificial (SCA) de tercera generación. Para ello, 12 participantes fueron evaluados sobre cuatro SCA, con características estructurales diferentes, mediante un test lineal de carrera a tres velocidades distintas (V1: 3,33 m/s, V2: 4 m/s y V3: velocidad máxima) con dos acelerómetros triaxiales situados en tibia y cabeza. El pico de aceleración en tibia fue significativamente menor en SCA4 (sub-base de terreno natural, mayor longitud de fibra y cantidad de relleno) a V3 y menor que SCA1 (fibra de menor longitud y menor cantidad de relleno) y SCA3 (mayor longitud de la fibra, mayor cantidad de relleno y sub-base asfáltica) a V1 y V2. Mientras SCA3, presentó una mayor atenuación con respecto a SCA1 y SCA2 (características estructurales similares a SCA1 y con capa elástica) a V1 y con SCA2 a V2. La capa elástica puede tener una influencia menor que la longitud de la fibra, la cantidad de relleno y la sub-base en la magnitud de los picos de impacto a velocidades máximas y en su capacidad de atenuación a velocidades lentas y moderadas.Peer ReviewedAward-winnin

Implementation of an End-to-End Standards-based Patient Monitoring Solution

A proof-of-concept design of a patient monitoring solution for intensive care unit environments has been presented. It is end-to-end standard-based, using ISO/IEEE 11073 (X73) in the bedside environment and EN13606 to communicate the information to an electronic healthcare record (EHR) server. At the bedside end, the system is a plug-and-play sensor network communicating with a gateway that collects medical information and sends the data to a monitoring server. The monitoring server transforms this information into an EN13606 extract to be stored on the EHR server. The system has been implemented to comply with the last X73 and EN13606 available versions and tested in a laboratory environment to demonstrate the feasibility of an end-to-end standard-based solution

Elastic scattering with weakly bound projectiles

Possible effects of the break-up channel on the elastic scattering threshold anomaly has been investigated. We used the weakly bound 6,7Li nuclei, which is known to undergo break-up, as projectiles in order to study the elastic scattering on a 27Al target. In this contribution we present preliminary results of these experiments, which were analyzed in terms of the Optical Model and compared with other elastic scattering data using weakly bound nuclei as projectile. © 2007 American Institute of Physics.Fil:Figueira, J.M.

Planck intermediate results. VIII. Filaments between interacting clusters

About half of the baryons of the Universe are expected to be in the form of filaments of hot and low density intergalactic medium. Most of these baryons remain undetected even by the most advanced X-ray observatories which are limited in sensitivity to the diffuse low density medium. The Planck satellite has provided hundreds of detections of the hot gas in clusters of galaxies via the thermal Sunyaev-Zel'dovich (tSZ) effect and is an ideal instrument for studying extended low density media through the tSZ effect. In this paper we use the Planck data to search for signatures of a fraction of these missing baryons between pairs of galaxy clusters. Cluster pairs are good candidates for searching for the hotter and denser phase of the intergalactic medium (which is more easily observed through the SZ effect). Using an X-ray catalogue of clusters and the Planck data, we select physical pairs of clusters as candidates. Using the Planck data we construct a local map of the tSZ effect centered on each pair of galaxy clusters. ROSAT data is used to construct X-ray maps of these pairs. After having modelled and subtracted the tSZ effect and X-ray emission for each cluster in the pair we study the residuals on both the SZ and X-ray maps. For the merging cluster pair A399-A401 we observe a significant tSZ effect signal in the intercluster region beyond the virial radii of the clusters. A joint X-ray SZ analysis allows us to constrain the temperature and density of this intercluster medium. We obtain a temperature of kT = 7.1 +- 0.9, keV (consistent with previous estimates) and a baryon density of (3.7 +- 0.2)x10^-4, cm^-3. The Planck satellite mission has provided the first SZ detection of the hot and diffuse intercluster gas.Comment: Accepted by A&
