La historia de las montañas contada por sus rocas

El Centro de Monitoreo de la Conservación del Ambiente, del Programa de las Naciones Unidas para el Medio Ambiente, declara a Colombia como un país megadiverso. Y esto se debe, en gran parte, a los miles de millones de años de procesos geológicos que han dado lugar a cordilleras, valles, sistemas de fallas y condiciones climáticas que propician que esta sea una de las 17 naciones que albergan el 70 por ciento de la biodiversidad del planeta. Por eso, Colombia no solo es un país megadiverso, también es geodiverso. El estudio de rocas de las cordilleras Occidental y Central permite a investigadores de EAFIT reconstruir la evolución de los Andes del norte, en Antioquia, desde hace millones de años hasta el último medio siglo. Entender su desarrollo y comportamiento es útil para temas de gestión del riesgo, amenaza sísmica y geoturismo

La Casa que Habla

La Casa que Habla es un museo transmedia que parte de un metaverso y talleres presenciales para resguardar la memoria de los objetos que poseemos a partir del diseño sostenible. Involucra a la comunidad en la consciencia sobre el impacto ambiental de sus hábitos de consumo y la disposición de los residuos sólidos voluminosos, generando cuidado del medio ambiente desde la preservación y reúso de muebles de madera y otros materiales factibles de reúso que han pasado de generación en generación en las familias. El proyecto se enmarca en una de las aristas de la sostenibilidad: el diseño sostenible, iniciativa que también ha venido tomando fuerza en el contexto de las economías circulares o verdes. El punto de partida es el modelo de negocio de Lurdes, Grupo MLP S.A.S, propiedad de la familia Merino Palacio, y en sus más de 30 años de experiencia en los temas de reúso y restauración de muebles. En este texto podrá encontrar el punto de partida e investigaciones con usuario desde un proyecto transmedia para generar consciencia ambiental.The Talking House is a transmedia museum that starts from a metaverse and face-to-face workshops to safeguard the memory of the objects we own based on sustainable design. It involves the community in raising awareness of the environmental impact of their consumption habits and disposal of bulky solid waste, generating care for the environment from the conservation and reuse of wooden furniture and other feasible reuse materials that have gone from generation to generation in families. The project is part of one of the pillars of sustainability: sustainable design, an initiative that has also been gaining strength in the context of circular or green economies. The starting point is the business model of Lurdes, Grupo MLP S.A.S, owned by the Merino Palacio family, and its more than 30 years of experience in the areas of furniture reuse and restoration. In this text you can find the starting point and user research for a transmedia project to generate environmental awareness

Juxtaposing BTE and ATE – on the role of the European insurance industry in funding civil litigation

One of the ways in which legal services are financed, and indeed shaped, is through private insurance arrangement. Two contrasting types of legal expenses insurance contracts (LEI) seem to dominate in Europe: before the event (BTE) and after the event (ATE) legal expenses insurance. Notwithstanding institutional differences between different legal systems, BTE and ATE insurance arrangements may be instrumental if government policy is geared towards strengthening a market-oriented system of financing access to justice for individuals and business. At the same time, emphasizing the role of a private industry as a keeper of the gates to justice raises issues of accountability and transparency, not readily reconcilable with demands of competition. Moreover, multiple actors (clients, lawyers, courts, insurers) are involved, causing behavioural dynamics which are not easily predicted or influenced. Against this background, this paper looks into BTE and ATE arrangements by analysing the particularities of BTE and ATE arrangements currently available in some European jurisdictions and by painting a picture of their respective markets and legal contexts. This allows for some reflection on the performance of BTE and ATE providers as both financiers and keepers. Two issues emerge from the analysis that are worthy of some further reflection. Firstly, there is the problematic long-term sustainability of some ATE products. Secondly, the challenges faced by policymakers that would like to nudge consumers into voluntarily taking out BTE LEI

Search for stop and higgsino production using diphoton Higgs boson decays

Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Impacts of the Tropical Pacific/Indian Oceans on the Seasonal Cycle of the West African Monsoon

The current consensus is that drought has developed in the Sahel during the second half of the twentieth century as a result of remote effects of oceanic anomalies amplified by local land–atmosphere interactions. This paper focuses on the impacts of oceanic anomalies upon West African climate and specifically aims to identify those from SST anomalies in the Pacific/Indian Oceans during spring and summer seasons, when they were significant. Idealized sensitivity experiments are performed with four atmospheric general circulation models (AGCMs). The prescribed SST patterns used in the AGCMs are based on the leading mode of covariability between SST anomalies over the Pacific/Indian Oceans and summer rainfall over West Africa. The results show that such oceanic anomalies in the Pacific/Indian Ocean lead to a northward shift of an anomalous dry belt from the Gulf of Guinea to the Sahel as the season advances. In the Sahel, the magnitude of rainfall anomalies is comparable to that obtained by other authors using SST anomalies confined to the proximity of the Atlantic Ocean. The mechanism connecting the Pacific/Indian SST anomalies with West African rainfall has a strong seasonal cycle. In spring (May and June), anomalous subsidence develops over both the Maritime Continent and the equatorial Atlantic in response to the enhanced equatorial heating. Precipitation increases over continental West Africa in association with stronger zonal convergence of moisture. In addition, precipitation decreases over the Gulf of Guinea. During the monsoon peak (July and August), the SST anomalies move westward over the equatorial Pacific and the two regions where subsidence occurred earlier in the seasons merge over West Africa. The monsoon weakens and rainfall decreases over the Sahel, especially in August.Peer reviewe
