The Copernicus Climate Change Service (C3S) provides open and free access to state-of-the-art climate data and tools for use by governments, public authorities, and private entities around the world. It is fully funded by the European Union and implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF) together with public and private entities in Europe and elsewhere. With over 120,000 registered users worldwide, C3S has rapidly become an authoritative climate service in Europe and beyond, delivering quality-assured climate data and information based on the latest science. Established in 2014, C3S became fully operational in 2018 with the launch of its Climate Data Store, a powerful cloud-based infrastructure providing access to a vast range of global and regional information, including climate data records derived from observations, the latest ECMWF reanalyses, seasonal forecast data from multiple providers, and a large collection of climate projections. The system has been designed to be accessible to nonspecialists, offering a uniform interface to all data and documentation as well as a Python-based toolbox that can be used to process and use the data online. C3S publishes European State of the Climate reports annually for policy-makers, as well as monthly and annual summaries that are widely disseminated in the international press. Together with users, C3S develops customized indicators of climate impacts in economic sectors such as energy, water management, agriculture, insurance, health, and urban planning. C3S works closely with national climate service providers, satellite agencies, and other stakeholders on the improvement of its data and services.

The Copernicus Atmosphere Monitoring Service (CAMS), part of the European Union’s Earth observation program Copernicus, entered operations in July 2015. Implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF) as a truly European effort with over 23,500 direct data users and well over 200 million end users worldwide as of March 2022, CAMS delivers numerous global and regional information products about air quality, inventory-based emissions and observation-based surface fluxes of greenhouse gases and from biomass burning, solar energy, ozone and UV radiation, and climate forcings. Access to CAMS products is open and free of charge via the Atmosphere Data Store. The CAMS global atmospheric composition analyses, forecasts, and reanalyses build on ECMWF’s Integrated Forecasting System (IFS) and exploit over 90 different satellite data streams. The global products are complemented by coherent higher-resolution regional air quality products over Europe derived from multisystem analyses and forecasts. CAMS information products also include policy support such as quantitative impact assessment of short- and long-term pollutant-emission mitigation scenarios, source apportionment information, and annual European air quality assessment reports. Relevant CAMS products are cited and used for instance in IPCC Assessment Reports. Providing dedicated support for users operating smartphone applications, websites, or TV bulletins in Europe and worldwide is also integral to the service. This paper presents key achievements of the CAMS initial phase (2014–21) and outlines some of its new components for the second phase (2021–28), e.g., the new Copernicus anthropogenic CO2 emissions Monitoring and Verification Support capacity that will monitor global anthropogenic emissions of key greenhouse gases.

Este título es alegórico. No me voy a referir exclusivamente a lo que han visto mis ojos, también hablaré de lo que he leído o me han contado, cómo era el Ecuador y el mundo cuando yo nací.El Ecuador era un país cacaotero con una población de 2.700.000 habitantes y una superficie de 300.000 kilómetros cuadrados, más grande de lo que es en la actualidad; un país laico, sin religión oficial, en el que se respetaba todas las creencias políticas y religiosas, las escuelas y colegios estatales eran laicos, aunque también había escuelas y colegios particulares, casi todos confesionales. Las cuatro universidades del Ecuador eran estatales.

Background Intravascular leiomyomatosis (IVL) is a histologically benign smooth muscle tumor arising from the uterus that can spread through the pelvic veins and can extend as far as the heart via the inferior vena cava. IVL is an extremely rare phenomenon, especially when the heart is involved. However, despite its benign characteristics, it can behave like a malignant tumor leading to significant morbidity and even mortality if left untreated. Case presentation The patient is a 42-year-old woman with a past medical history of uterine leiomyomas. Recently she developed heavy bleeding and frequent spotting; therefore consulted with her gynecologist. After further evaluation, a mass within the uterus that expanded into the pelvic veins, inferior vena cava, and right atrium was discovered. After the complete removal of the mass, the patient underwent full recovery. IVL with cardiac extension was the final diagnosis. Conclusion Although IVL is rare, it must be considered in women who underwent previous hysterectomies or myomectomies and presented with pelvic masses or symptoms of right heart failure. The ideal treatment will require the joint efforts of a complete multidisciplinary team, the patient's symptoms, previous operative history, the tumor's extension, and resectability.

Copper nanoparticles (NPs) and ZrO2-supported copper NPs (Cu NPs/ZrO2) were synthesized via a chemical reduction method applying different pH (4, 7 and 9) and evaluated in a glycerol dehydration reaction. Copper NPs were characterized with transmission electron microscopy (TEM) and UV–vis spectroscopy. Transmission electron microcopy (TEM) results revealed a homogeneous distribution of copper NPs. A hypsochromic shift was identified with UV–vis spectroscopy as the pH of the synthesis increased from pH = 4 to pH = 9. Zirconia-supported copper NPs catalysts were characterized using N2 physisorption, X-ray diffraction (XRD), TEM, X-ray photoelectron spectroscopy (XPS), temperature-programmed reduction (TPR), temperature-programmed desorption of ammonia (NH3-TPD) and N2O chemisorption. The presence of ZrO2 in the chemical reduction method confirmed the dispersion of the copper nanoparticles. X-ray diffraction indicated only the presence of tetragonal zirconia patterns in the catalysts. XPS identified the Cu/Zr surface atomic ratio of the catalysts. TPR patterns showed two main peaks for the Cu NPS/ZrO2 pH = 9 catalyst, the first peak between 125 and 180 °C (region I) was ascribed to more dispersed copper species, and the second one between 180 and 250 °C (region II) was assigned to bulk CuO. The catalysts prepared at pH = 4 and pH = 7 only revealed reduction at lower temperatures (region I). Copper dispersion was determined by N2O chemisorption. With NH3-TPD it was found that Cu NPs/ZrO2 pH = 9 exhibited the highest total quantity of acidic sites and the highest apparent kinetic constant, with a value of 0.004 min−1. The different pH applied to the synthesis media of the copper nanoparticles determined the resultant copper dispersion on the ZrO2 support, providing active domains for glycerol conversion.

The main purpose of this research is to discuss the use of passive systems and strategies applicable to buildings and which have a direct impact on public spaces, focusing on methods for the modification of interior comfort, as well as on energy optimization. An additional major goal is for the outcomes of the technical-architectural analysis to help in the development of a projection and design language. Specifically, the aim is preparing a design strategy report with which to set a precedent for a formal optimized design in new or modified works.

We present the discovery of 32 new double periodic variables (DPVs) located toward the Galactic bulge. We found these objects among the nearly half a million binary stars published by the Optical Gravitational Lensing Experiment project. With this discovery, we increase the number of known DPVs in the Milky Way by a factor of 2. The new set of DPVs contains 31 eclipsing binaries and one ellipsoidal variable star. The orbital periods cover the range from 1.6 to 26 days, while long periods are detected between 47 and 1144 days. Our analysis confirms a known correlation between orbital and long periods that is also observed in similar systems in the Magellanic Clouds., Comment: 8 pages, 7 figures

Congenital anomalies of the inferior vena cava (IVC) are caused by an abnormal persistence or regression of embryonic precursor veins; they are usually incidental findings on imaging studies. These rare conditions have a 0.6% prevalence in individuals with congenital heart diseases and 0.3% in healthy patients. The purpose of this paper was to report two cases of interruption of IVC with hemiazygos continuation and its implications during surgery, highlighting that after recognizing this anomalous drainage the surgeon should be prepared to change the surgical strategies, especially in cardiovascular surgery, in order to obtain adequate circulatory flows or surgical exposure where venous cannulation could be difficult. We have also reported two cases of healthy patients with the same isolated IVC anomaly with no clinical repercussions, which can develop in the future.

El Hotel Samarina está ubicado frente al mar, en la cota +12 m s.n.m., en el cantón La Libertad, Provincia de Santa Elena. Fue construido al final de la década de los 50. El hotel Samarina terminado en un 70%, se compone de planta baja y tres pisos altos y estructuras de hormigón armado. La superficie total del mencionado hotel es de 2638 m2. Actualmente, se conoce que en el Ecuador y principalmente en la Provincia de Santa Elena, presenta una alta sismicidad por estar ubicada cercana a la zona de subducción de la placa de nazca y la placa sudamericana. A través de una evaluación y diagnóstico estructural, conforme a las normas ecuatorianas NEC 2011 o códigos uniformes de edificación UBC 97 la actual edificación no cumple el diseño sismoresistente, y de acuerdo al conocimiento actual se elaboró un diseño moderno donde se mejoró su nivel de desempeño o comportamiento sismo resistente ante la acción de un sismo moderado, y con la aplicación de un software libre denominado ETAB's se implementó un modelo con sistema de reforzamiento, compuesto de disipadores de energía colocados en las caras laterales y reforzamiento de columnas en los cuatro niveles que componen el edificio. ABSTRACTThe Samarina Hotel is located close to the sea, at 12 m s.n.m., at La Libertad, Province of Santa Elena. It was constructed at the end of the decade of the 50. The hotel has a ground floor and three high floors and it has reinforced concrete structures with surface of 26382. In the Ecuador and principally at Province of Santa Elena, has a high seismicity conditions because of it are located near to the zone of subduction of the Nazca South plates. An evaluation and structural diagnosis was performed, according to NEC 2011 proceeding, and also with the uniform codes of building UBC97. It is important to indicate that the actual building does not fulfill the design seismic resistant requirements. To improve the level resistant earthquake was performed. A system of reinforcement, spendthrifts' compound of energy placed in the lateral faces and columns reinforcement in four levels that compose the building was implemented with the software free ETAB's.

The cutting stock problem has been studied in the context of different industrial applications inducing NP-hard problems in most instances. However, the application in sawmill has not received the same attention. In this paper, we deal with the problem of determining the number of logs to cut over a period of several days and the geometry of sawmill patterns in order to satisfy the demand while minimizing the loss of material. First, the problem is formulated as an integer programming problem of the form of a constrained set covering problem where the knowledge of a priori cutting patterns is necessary to generate its columns. In our implementation, these patterns are obtained using a genetic algorithm (GA) or a simulated annealing method (SA). Then, two different approaches are introduced to solve the problem. The first approach includes two methods that combine a metaheuristic to generate the number of logs and a constructive heuristic to generate the cutting patterns for each of the logs. In the second approach, we use an exact procedure CPLEX to solve the integer programming model where the cutting patterns are generated with the GA method (GA+CPLEX) or the SA method (SA+CPLEX). These four methods are compared numerically on 11 semi-randomly generated problems similar to those found in real life. The best results for the loss are obtained with the two-stage GA+CPLEX approach that finds the best values for 7 problems.

The Septuagint (LXX) is in many ways a remarkable collection of texts. It represents the first known attempt to translate the Hebrew Bible into an Indo-European language, namely Hellenistic Greek. Historians of the beginnings of Christian philology should readily appreciate the influence of medium and technology on the construction of knowledge about the LXX. The files available at Center of Computer Analysis of Texts (CCAT)'s gopher are simple text documents featuring the text of Alfred Rahlfs' 1935 hand edition of the Septuagint. Research on the LXX lexis has been shaped by the dialectics between two ostensibly antithetical paradigms, each departing from a different yet plausible insight. Corpus linguistics is one of the fastest growing approaches in linguistics and is particularly relevant for LXX lexicography. Having the aforementioned rich network of resources openly available at the disposal of the LXX scholar would be a great achievement in itself.
